Technical Field

The present invention relates to a production line for enabling to produce both a plasterboard and a low-density building block which has a gypsum-based foam core and surfaces of which are coated with a cardboard or gauze-like material and also a cement-based board on the same production line.

Background of the Invention

Among the most frequently used construction elements, wall materials are particularly the most commonly used ones today.

Wall materials can be divided into two groups in terms of their dry and wet application properties. Wet-applied wall materials essentially consist of prismatic building blocks which are interconnected by means of a mortar. The most frequently used ones are solid or hollow bricks which are obtained by firing clay, briquettes obtained from cement and sand/aggregate mixture, or pumice (bims) block by mixture of pozzolanic aggregates such as pumice in order to be lighter. Bricks and pumice blocks are classified as heavy construction elements because their densities are heavier than 1.000 kg/m ³ and they are not preferred in general because of seismic concerns. A gas (aerated) concrete with a plenty of air space is a wet-applied building block which is obtained by autoclave curing after blow moulding by adding gas-generating aluminium cake together with cement, lime and silica sand. Whereas dry-applied construction elements are boards in the form of a layer being usually thinner than 20 mm which are definitely fixed on a wooden or metal carrier construction for example by means of screws. The most commonly used ones are plasterboards both sides of which consist of a cardboard-coated gypsum core, and are cement-based boards mixed with aggregate which are reinforced from surface by net or gauze or from core by various fiber.

The fact that a gypsum blend wherein water is mixed by means of a suitable mixer can harden in a very short time after being laid between two cardboards on the belt is the reason why plasterboards -which are obtained by continuous production on the belt- are relatively cost efficient. The said short time implies that the gypsum mortar hardens before 5 minutes, preferably even before 3 minutes, and it can be brought to a consistency hardness cuttable in a desired size. Relatively early setting (hardening) characteristic of gypsum is the reason why plasterboard is the most produced construction element in the world.

A production process carried out in plasterboard production facilities essentially enables to produce a plasterboard continuously on a continuous belt at first and thereafter on a roller conveyor being arranged successively at frequent intervals, until it reaches a self-bearing hardness after a gypsum blend is shaped in dimensions to have 60 - 125 cm width and less than 20 mm thickness in general upon it is mixed in a suitable mixer continually and then taken between two cardboards. Then, the continuous board passing through saws placed on a double drum is broken off in a desired length by triggering the drums operating in tandem. The wet board brought to a desired length is taken into a drying oven in order that the high water contained within its structure is received upon being evaporated. Plasterboard drying ovens being used in the state of the art are multi-layer ovens. Hot air is blown to boards which move on the rollers being arranged successively, from both top and bottom. The said hot air is approximately 260°C at the first parts of the oven and it decreases to approximately 100°C at the ends of the oven. The rollers inside the oven are moved by means of a chain. Plasterboards are relatively low-weight because they have a thickness less than 20 mm, and they are usually embedded by carbon bearings due to their high-temperature resistance characteristic so that the rolls can rotate.

Angle roller conveyors, one head of which is fixed with a joint assembly and the other end thereof can move to each layer level, are used in order to feed the boards to each layer of the oven. The boards received from each layer by a similar angle conveyor at the exit of the oven are put down to a single line again. The plasterboards allow being directed downwards or upwards by a relatively specific angular bending while moving on the line, by means of two cardboards they have and thickness less than 20 mm.

The plasterboards leaving the drying oven are provided for consumption in a commercial size and quantity after being taken to a cutting unit which is suitable for bringing them into a final size and then to a bundling and/or palletizing/packaging unit.

Due to the fact that cement hardens in a quite long time compared to gypsum (more than 12 hours), it was started to produce cement-based construction elements (boards) in industrial size almost a century later than gypsum-based building elements (boards). Upon improvement of recipes which are also able to set under relatively 10 minutes in cement-based blends, it was started to produce cement- based boards reinforced with alkali-resistant glass fiber mesh since the 1980s. However, no drying process is included in cement-based board production lines. Curing is performed in humid cabins or tunnels instead of drying units.

Beginning of production of cement-based boards reinforced with alkali-resistant glass fiber mesh is as in the case of plasterboards. Here, glass fiber gauze is used at the bottom whereas glass fiber gauze or glass fiber mesh is used on the top instead of upper/lower cardboard.

A production process carried out in cement-based board production facilities essentially enables to produce boards continuously on a continuous belt at first and thereafter on a roller conveyor being arranged successively at frequent intervals, until they reach a self-bearing hardness after a cement and filling material blend is shaped in dimensions to have 60 - 125 cm width and less than 20 mm thickness in general as in the case of plasterboards upon it is mixed in a suitable mixer continually. Then, the continuous board passing through the saws placed on the double drum is broken off in a desired length by triggering the drums. The wet cement-based board brought into a desired length is kept in a suitable cabin or tunnel until it reaches a self-bearing hardness entirely by being maintained under high humidity for a certain period of time by means of the water contained within its structure. This process is also known as damp curing process. The curing units are multi-layer units consisting of roller conveyors just like the plasterboard ovens. Hot pulverized water is occasionally sprayed to the cement-based boards which move on the rollers being arranged successively, from both top and bottom. The said temperature is approximately 90°C in the first parts of the oven whereas it decreases to approximately 50°C at the ends of it. The rollers inside the curing unit are moved by means of a chain as in the case of the plasterboard ovens. Cement- based boards are relatively low-weight because they thinner than 15mm and they are usually embedded by bronze bearings so that the rolls can rotate.

Cement-based boards do not have bending characteristic when they are wet, like plasterboards. Because cement bonds of the boards, final setting of which still continue, are being dissolved in angular change movements; the board should not be bended in any way at this stage. The cement board cut is taken onto a conveyor belt or a roller conveyor and the cement board is kept immobile by stopping the conveyor. The said conveyor is located on a lift system. The conveyor, which is take to a desired layer level by the lift system, is operated again and the wet cement board thereof is transferred to the desired layer of the curing unit. Similarly, the cured cement board received from the layers of the curing unit by means of a similar lift conveyor system is put down onto a single line.

The cement-based boards leaving the curing unit are then kept in a store until they acquire their final strengths and thereafter, as in the case of production of plasterboard, they are provided for consumption in a commercial size and quantity after being taken into a cutting unit which is suitable for bringing them into a final size and then into a bundling and/or palletizing/packaging unit.

Production of a low-density building block, which has a gypsum-based foam core and surfaces of which are coated with a cardboard or gauze-like material, is disclosed in Turkish patent document no. TR2019/06279 pertaining to the same applicant in detail.

Production of the said gypsum-based building block begins like production of the plasterboard. The gypsum blend is shaped on a belt in the form of a slab with 50 or 60 cm width and up to 50 to 250 mm thickness in general upon it is mixed in a suitable mixer continually and then taken between two cardboards. After shaping, it is produced continuously on a continuous belt at first and thereafter on a roller conveyor being arranged successively at frequent intervals, until it reaches a self- bearing hardness. Then, it is cut into a desired length by means of a wire saw operating on a moving assembly synchronous to the belt speed. Drying ovens are used for the process of receiving the high water contained within the structure of the wet gypsum block slab being cut into the desired length, by being evaporated. Just like plasterboard drying ovens, gypsum block ovens are multi-layer ovens as well. Hot air is blown to the gypsum block slabs which move on the rollers being arranged successively, from both bottom and top. The said hot air is approximately 260°C in the first parts of the oven and it decreases to approximately 100°C at the ends of the oven, as in the case of the plasterboard drying ovens. The rollers inside the plasterboard slab ovens are moved by means of a chain too. The slabs are heavy because they are produced up to 250 mm thickness on demand and they are embedded by a specific ball or roller bearing having both high load-carrying capacity and ability to withstand high temperature, preferably 350° C, so that the rollers can rotate.

Plasterboard slabs do not have bending characteristic when they are wet like plasterboards. Just as in the case of production of cement board, the plasterboard slabs are also taken onto a conveyor belt or roller conveyor and the slabs are kept immobile by stopping the conveyor. The said conveyor is located on a lift system. The conveyor, which is brought to a desired layer level by the lift system, is operated again and the wet slab on thereof is transferred to the desired layer of the oven. The gypsum block slabs, which are relatively or fully dried, are put down onto a single line after being received from the layers of the related oven by means of a similar lift conveyor system. They are provided for consumption in a commercial size and quantity after being taken to a cutting unit which is suitable for bringing them into a final size and then into a bundling and/or palletizing/packaging unit.

Each of the production lines wherein both production of plasterboard and production of gypsum-based block and also production of cement-based board are performed, are separate production lines. None of these production lines can realize the production of the other one. In other words, production of a cement-based board or production of a gypsum-based block cannot be realized in the production line enabling production of plasterboard in the state of the art. The board clearance of the plasterboards, which are produced in less than 20 mm thickness, in the distance between drying oven layers is spaced according to the production of board having a maximum thickness of 25 mm. Therefore, blocks having 250 mm thickness cannot be taken even if they are subjected to the same drying process. Distribution between the oven layers require lift units in production of a gypsum block despite the conveyor operating angularly in plasterboard production lines. Similarly, a lift distribution system is included in production of cement-based boards as in the case of production of gypsum blocks however, although curing units have layers and rollers like drying ovens, they also have assemblies spraying hot water while operating at relatively much lower temperatures.

Promoting both plasterboard and cement-based boards in emerging markets is provided by importing them from abroad until the minimum production level is reached. Performing production of plasterboards and production of cement-based boards at the same time is not seen in most countries. Production of plasterboards is performed in many countries of the world whereas production of cement-based boards is available in 10 countries in total worldwide. In buildings, it is usually proceeded to the phase of dry construction material such as plasterboard after mortared building blocks such as brick, briquette or aerated concrete and then richness of dry construction material solutions are attained both inside and outside by means of cement-based board phase.

Therefore, there is need for a production line enabling to produce three different products such as both plasterboard and cement-based board and also low-density building block which has a gypsum-based foam core and surfaces of which are coated with a cardboard or gauze-like material in the state of the art.

Summary of the Invention

An objective of the present invention is to realize a production line enabling to produce three different products such as both plasterboard and cement-based board and also low-density building block which has gypsum-based foam core and surfaces of which are coated with a cardboard or gauze-like material. Another objective of the present invention is to realize production of construction elements such as both gypsum-based wall block and plasterboard and also cement- based board continuously on a belt in the same production line without using a moulding technique.

Another objective of the present invention is to provide an investment economy by producing 3 different products on a single line instead of setting up separate production lines for each product. In this context, providing building solutions for emerging markets by means of dry construction materials both in indoors and outdoors at the same time constitutes one of the main objectives of the invention.

Another objective of the present invention is to ensure that emerging markets have rich building solutions beforehand by means of dry construction materials by producing 3 different products on a single production line and thereby providing the benefits to be achieved through the use of the capacity that may adapt to the development of demands of emerging markets for products as much as possible, to the market.

In a preferred embodiment of the invention, the unloading device (12) comprises a lift- like raising/lowering mechanism which is adapted to take the dry product (F) being heat-treated in the related layers of the heat treatment device (9) to the level of the carrier group.

In one embodiment of the invention, the conveying group comprises a first conveyor (13) which extends almost between the mixer (4) and the extruder (7), and is adapted to ensure that the mortar (A) fed from the mixer (4) is distributed on the lower carrier (B) such that it is almost homogeneous. In a preferred embodiment of the invention, the first conveyor (13) is an oscillating-type belt conveyor.

In one embodiment of the invention, the conveying group comprises at least one second conveyor (14) which extends almost between the extruder (7) and the cutter (8) and ensures that the continuous slab (D) leaving the extruder (7) is set on it in such a level that it can be cut by the cutter (8).

In one embodiment of the invention, the conveying group comprises a third conveyor (15) which extends almost between the cutter (8) and the loading device (11) and is able to move faster than the second conveyor (14) in order that the wet product (E) cut from the continuous slab (D) is separated from the slab (D) easily.

In one embodiment of the invention, the conveying group comprises a fourth conveyor (16) which extends almost between the loading device (11) and the heat treatment device (9) and is adapted to ensure that the wet product (E) is fed from the loading device (11) to the related layer of the heat treatment device (9).

In one embodiment of the invention, the conveying group also comprises a trimming and bundling device (18) which is adapted to trim the dry product (F) - becoming completely dry by being heat-treated- in order to convert it into the final product (G) such that its edges have a certain size and to bundle it according to the package to be marketed.

In one embodiment of the invention, the conveying group also comprises a sixth conveyor (18) extends almost between the unloading device (12) and the trimming and bundling device (18), and is adapted to feed the said dry product (F) to the trimming and bundling device (18) in order that the dry product (F) being heat- treated becomes the final product (G).

In a preferred embodiment of the invention, the inner surface of the mixer (4) enabling formation of the mortar (A) is made of a material which is resistant to the corrosive effect of cement having high corrosive characteristic or it is coated with this type of material.

In one embodiment of the invention, the loading device (11) comprises a plurality of first feeders (2) which are customized for cement-based liquid additives and gypsum -based liquid additives and a plurality of second feeders (3) which are customized for cement-based solid additives and gypsum-based solid additives.

In one embodiment of the invention, the cutter (8) comprises drum saws -both of which operates in tandem- adapted to cut the continuous slab (D) during production of the plasterboard and the cement board and wire saw adapted to cut the continuous slab (D) during production of the gypsum-based building block.

In a preferred embodiment of the invention, the heat treatment device (9) comprises specific roller-type bearings being resistant to high temperature and allowing to embed conveying means such as roller, chain, belt which enable to move the wet product (E) entering in thereof or the almost dry product (F) being obtained as a result of the heat treatment carried out, into the heat treatment device (9) from the inlet to the outlet of the heat treatment device (9).

When it is desired to produce plasterboard or gypsum-based building block by means of the inventive production line (1), gypsum -based liquid additives and gypsum-based dry additives are fed from the first feeder (2) and the second feeder (3) to the mixer (4) in suitable ratios of suitable recipe components and the mortar (A) is composed by mixing these inside the mixer (4). While for example a paper like subcarrier (B) fed f subcarrier (B) rom the first coil (5) is passing under the mixer (4) on the first conveyor (13), the gypsum-based mortar (A) received from the mixer (4) is discharged onto the subcarrier (B) and it is distributed onto the subcarrier (B) almost homogeneously preferably by means of the oscillating structure of the first conveyor (13). For example a paper-like upper coating (C) fed from the second coil (6) is laid onto the mortar (A) by means of its characteristic of being adjustable at a suitable height in the range of 10 to 250 mm until a desired thickness is given via paper flanging apparatus which enable the lower carrier (B) to curve at both edges of the first conveyor (13) of an oscillating-belt conveyor type and which are classic in the plasterboard industry, and a continuous slab (D) form is obtained by passing the group consisting of the lower carrier (B), the mortar (A) and the upper coating (C) obtained from an extruder (7) providing certain thickness. The continuous slab (D) obtained is fed to the cutter (8) preferably until the mortar (A) on the second conveyor (14) sets in such a level that it can be cut by the cutter (8). The wet product (E) is obtained by cutting the continuous slab (D) inside the cutter (8). Because the plasterboards are preferably produced in less than 25 mm thickness, the said continuous slab (D) is cut upon the saws coinciding with each other break off the slab (D) following the movement of the drum saws -preferably both of which operates in tandem- inside the cutter (8), and the wet product (E) is obtained. Whereas in production of plasterboard, the continuous slab (D) entering the cutter (8) is cut preferably by saws operating synchronously with the line inside the cutter (8), and the wet product (E) is obtained. In a preferred embodiment of the invention, the cutting assembly having tandem drum is arranged such that it will be closer to the inlet of the cutter (8) than the wire saw inside the cutter (8). In this embodiment, when it is desired to produce plasterboard by means of the inventive production line (1), for example the wire saw is lifted up and taken into a position wherein it will not contact the continuous slab (D) fed into the cutter (8) ant the cutting transaction is carried out only by the tandem drum cutter inside the cutter (8). Contrary to this, when it is desired to produce gypsum-based building block by means of the inventive production line (1), a wire saw cutter operating on an assembly with a motion synchronous to the belt speed is operated while the tandem drums are not operated. The wet product (E) obtained by cutting the continuous slab (D) inside the cutter (8) suitably is moved away from the slab (D) by being accelerated on the third conveyor (15) operating faster than the second conveyor (14) and it is carried to the loading device (11). The loading device (11) comprising preferably a lift-like raising/lowering mechanism is necessary for production of gypsum-based building blocks which are not suitable for bending during production particularly because of its weight, and there is no obstacle for use of the said loading device (11) in production of a plasterboard being able to bend to a certain degree essentially due to its low thickness during production. The said loading device (11) can be used consecutively one or more times in necessary number depending on the capacity of the production line (1) and the number of layers that the heat treatment device (9) has and the wet product (E) is transmitted to the related layer of the heat treatment device (9) by means of the fourth conveyor (16). Drying transaction of the wet product (E) is carried out by operating the heat treatment device (9) such that it is an oven at high temperature and low humidity in production of gypsum- based products, i.e. plasterboard or gypsum-based building block. Number and length of the layers of the heat treatment device (9) can be adjusted based on the capacity of the production line (1). The dry product (F) obtained by drying the wet product (E) in the heat treatment device (9) is carried to the unloading device (12) comprising a lift-like raising/lowering mechanism by means of the fifth conveyor (17) and it is put onto the sixth conveyor (19) by means of the raising/lowering mechanism from there. The final product (G) is obtained after sending the dry product (F) to the trimming and bundling device (18) in order to be trimmed as known and applied in industry conventionally, such that the edges of the product will be brought into a desired size and to be laid according to the package to be marketed and following the transactions carried out in the trimming and bundling device (18).

When it is desired to produce cement-based board by means of the inventive production line (1), cement-based liquid additives and cement-based dry additives are fed from the first feeder (2) and the second feeder (3) to the mixer (4) in suitable ratios of suitable recipe components and the mortar (A) is composed by mixing these inside the mixer (4). While for example a blanket-like subcarrier (B) fed f subcarrier (B) rom the first coil (5) is passing under the mixer (4) on the first conveyor (13), the cement-based mortar (A) received from the mixer (4) is discharged onto the subcarrier (B) and it is distributed onto the subcarrier (B) almost homogeneously preferably by means of the oscillating structure of the first conveyor (13). For example a blanket or mesh-like upper coating (C) fed from the second coil (6) is laid onto the mortar (A) by means of its characteristic of being adjustable at a suitable height in the range of 6 to 20 mm until a desired thickness is given via blanket flanging apparatus which enable the lower carrier (B) to curve at both edges of the first conveyor (13) of an oscillating-belt conveyor type, and a continuous slab (D) form is obtained by passing the group consisting of the lower carrier (B), the mortar (A) and the upper coating (C) obtained from an extruder (7) providing certain thickness. The continuous slab (D) obtained is fed to the cutter (8) preferably until the mortar (A) on the second conveyor (14) sets in such a level that it can be cut by the cutter (8). The wet product (E) is obtained by cutting the continuous slab (D) inside the cutter (8). Because the cement boards are preferably produced in less than 25 mm thickness, the said continuous slab (D) is cut upon the saws coinciding with each other break off the slab (D) following the movement of the drum saws -preferably both of which operates in tandem- inside the cutter (8), and the wet product (E) is obtained. The wet product (E) obtained by cutting the continuous slab (D) inside the cutter (8) suitably is moved away from the slab (D) by being accelerated on the third conveyor (15) operating faster than the second conveyor (14) and it is carried to the loading device (11). The said loading device (11) can be used consecutively one or more times in necessary number depending on the capacity of the production line (1) and the number of layers that the heat treatment device (9) has and the wet product (E) is transmitted to the related layer of the heat treatment device (9) by means of the fourth conveyor (16). Drying transaction of the wet product (E) is carried out by operating the heat treatment device (9) such that it is a curing device at a relatively lower temperature and higher humidity in production of cement-based board. By also operating the liquid spraying device (10) during the curing transaction inside the heat treatment device (9) of the wet product (E), it is ensured that the cement is cured under humidity inside the heat treatment device (9). Number and length of the layers of the heat treatment device (9) can be adjusted based on the capacity of the production line (1). The dry product (F) obtained by drying the wet product (E) in the heat treatment device (9) is carried to the unloading device (12) comprising a lift-like raising/lowering mechanism by means of the fifth conveyor (17) and it is put onto the sixth conveyor (19) by means of the raising/lowering mechanism from there. The final product (G) is obtained after sending the dry product (F) to the trimming and bundling device (18) in order to be trimmed as known and applied in industry conventionally, such that the edges of the product will be brought into a desired size and to be laid according to the package to be marketed and following the transactions carried out in the trimming and bundling device (18). Besides, it may be required to keep the final product (G) leaving the trimming and bundling device (18), in stock for a certain time in order that the cement can have its final strength depending on the mortar recipe used for production of the cement-based board and the time spent in the heat treatment device (9). Overall sizes of an exemplary embodiment of the production line (1) according to the present invention are provided in the Table 1 set out below.

Table 1: Information about an exemplary production line

Production capacity of the exemplary production line (1) shown in the Table 1 are provided in the Table 2, based on their types of production Table 2: An exemplary line capacity based on production types

Installed capacities of plasterboard facilities in Turkey are between 6 - 30 million m ² /year. Whereas installed capacities of aerated concrete plants are between 250 to 550 000 m ³ /year. A cement-based plasterboard facility has not been available in

Turkey until the exemplary facility shown above. The closest cement-based plasterboard facility to Turkey is in Greece.

Due to the fact that heat treatment device (9) included in the inventive production line (1) can be adjusted such that it will be operated at high temperature and low humidity for gypsum-based products and at relatively lower temperature and higher humidity for cement-based products, production of both gypsum-based products such as plasterboard and gypsum-based block and also cement-based boards can be realized by means of a single production line (1). In this case, it is enabled to produce 3 different building elements produced on separate production lines on a single production line and thereby, to provide a significant cost advantage in facility establishment. It is possible to develop various embodiments of the inventive production line (1); the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
