TECHNICAL FIELD

The invention relates to a machine capable of cutting to create a joint gap on the concrete in order to facilitate the construction of the structure and reduce the stresses that can cause cracking, cleaning the wastes generated during the cutting process, taping to prevent joint primer/filler or other waste from spilling out of the gap and priming the opened gap simultaneously, in reinforced concrete structures containing concrete.

STATE OF THE ART

Joints are planned gaps in the continuity of concrete floors. A joint is also defined as a gap filled with another binding material that separates two building elements in horizontal or vertical directions. Joints are used in floors that sit on the ground for two main reasons; facilitating construction and reducing stresses that can lead to cracking. To facilitate construction, most floor concrete is divided into several slabs made on different days, and the joints between these slabs are called building (construction or work) joints. In addition to these joints, the floor concrete also contains stress relief joints. According to their function, they are classified as insulation joints, building (construction or work) joints, expansion joints, contraction (shrinkage) joints, bending joints.

Today, especially in order to ensure the continuity of the concrete building parts that make up a floor, it is necessary to cut the joints on the concrete building piece and cover these joints with a joint filler. These joints both facilitate the construction and prevent cracks that may occur in the concrete structure part and reduce the durability of the concrete structure. For this reason, joint cutting is of great importance in the construction of concrete structures.

In the state of the art, joint cutting and filling process is generally done by cutting the joint, the wastes are cleaned manually, the tape is pulled by hand on the cut joint edges, the silicone wick is placed in the cut places by hand, and then followed by the manual filling of the joint filler. The patent document titled "Precision Cutting Device of Concrete Surfaces" with the publication number "WO9105645A1” has been determined in the literature search carried out in the state of the art. When the relevant document is examined, the concrete cutting machine provides the creation of smooth and linear joint cuts on the floor for the purpose of repairing a concrete floor, and contains a carrier carrying this system, a table positioned on this carrier and a blade and a motor positioned on the concrete floor, which are located on the table. Only cutting is done with the relevant machine, and there is no system that cleans the cut waste, pulls tape to the edge of the opened joint gaps, and fills/primers.

Another document in the state of the art is the patent application no “TR2017/22976” titled “A Joint Cutting and Filling Machine for Concrete Construction Pieces”. When said patent document is examined, it is mentioned that a machine that performs the cutting process to create joint gaps on the concrete and then the filling process from a single source. With this system, the wastes formed after the cutting process are sprayed around by air drive without being collected in a chamber, and taping is not performed to prevent the filling/primer material from overflowing to a place other than the joint gaps/crevices.

As a result, the existence of the above problems and the inadequacy of the existing solutions made it necessary to make a development in the technical field related to the joint cutting, cleaning, taping, filling/priming operations.

AIM OF THE INVENTION

The present invention relates to a machine that performs joint cutting, cleaning, taping and priming operations at the same time, which meets the above-mentioned requirements, eliminates all disadvantages and brings some additional advantages.

The main aim of the invention is to provide a machine capable of cutting to create a joint gap on the concrete in order to facilitate the construction of the structure and reduce the stresses that can cause cracking, cleaning the wastes generated during the cutting process, taping to prevent joint primer/f iller or other waste from spilling out of the gap and lining the opened gap simultaneously, in reinforced concrete structures containing concrete. The aim of the invention is to present a machine in which the vertical height of the cutter base, which performs the cavity formation process in the concrete, can be adjusted. Thus, it will be ensured that the vertical depth of the joint gap to be created can be adjusted.

Another aim of the invention is to provide a machine with adjustable horizontal width of the taping during the edge taping process, so that the lining material does not go out of the gap or the wastes formed during the cutting process do not spill out before the cutting process.

Another aim of the invention is to present a machine in which the primer density can be adjusted according to the joint gap depth or the desired priming ratio.

Another aim of the invention is to present a machine that minimizes labour cost and possible workmanship defects by performing the operations of taping on the edges of the joint gap, cutting the joint, cleaning the wastes, placing the wick on the cut places, filling the joint primer after the wick on the same body.

DETAILED DESCRIPTION OFTHE INVENTION

In this detailed explanation, the preferred embodiments of the concrete joint cleaning and filling machine (A) that is the subject of the invention are explained only for a better understanding of the subject and without any limiting effect. In reinforced concrete structures containing concrete, joint formation is performed on the concrete in order to facilitate the construction of the structure and to reduce the stresses that may cause cracking.

Concrete joint cleaning and filling machine (A) the general view of which is given in Figure-1 and Figure-2 basically comprises the main body (2) on which all the elements are located and positioned parallel on the work piece (1), at least one actuator (3) that provides the necessary power for the cutting process and other mechanisms of the system, the cutting mechanism (8) that performs the gap creation process on the concrete and the vertically adjustable cutter base (4) on which it is positioned, control panel (5) through which the startstop process of the machine and the necessary electronic components are controlled, the cleaning and vacuum mechanism (6), where the concrete wastes formed by the cutting process are collected, the taping mechanism (9), which covers the gap edges created by masking to prevent the filling/priming material from contaminating or damaging it, the wick reel (13), which ensures the laying of the wick to be placed in the joint gap, priming mechanism (11), which provides filling the joint cavity with fluid material, the front guide (7), which enables the machine to find and follow the path it needs to go, and the rear guide (16) that sits in the cut joint and prevents the machine axis from slipping.

In order to ensure that said cutting mechanism (8) creates a joint gap at the desired depth, there is a vertical adjustment arm (12) that allows the cutter base (4), on which it is positioned, to move vertically up and down on the main body (2). The attachment and movement transmission between the vertical adjustment arm (12), the cutter base (4) and the main body (2) is provided by the connection element (14). Said vertical adjustment arm (12) is preferably manually driven and can also be adjusted from the control panel (5) by means of a drive element, depending on demand and appropriate configuration.

Figure - 3 shows the detail view of the cleaning and vacuum mechanism (6) where the wastes formed after the cutting process are collected. Said mechanism comprises vacuum cleaner actuator (6.2), which creates a vacuum with the power it receives from the actuator (3), the chamber (6.1) in which the wastes are collected, the hose (6.3) that carries the wastes with the effect of vacuum positioned between said chamber (6.1) and the cutting mechanism (8) and a brush (6.4) that collects the wastes caused by the cut joint in front of the vacuum air coming from the hose (6.3). After the joint gap is created and the wastes are cleaned, tape is laid on the edges of the gap by means of the taping mechanism (9). The width of said tape can be adjusted with an adjustment element (9.1) on the body on which the tape is wound.

There is also a wick mechanism (13) for laying solid wick in the joint gap. The wicks stored on the reel in said mechanism are laid in the joint gap opened by the movement of the machine.

Finally, the fluid material is laid in the joint spaces where the wick is placed, by means of the priming mechanism (11). In said mechanism, there is a tank where the priming material in fluid form is stored and a distributor (11.1) that allows the fluid coming from said tank to be poured into the joint space. Said distributor (11.1) ensures that the priming filler is placed homogeneously and to the required extent.

There is a battery (10) that provides the electrical power required by the concrete joint cleaning and filling machine (A) actuator (3) or the control panel (5).

Brief operation of the concrete joint cleaning and filling machine (A) is as follows:

The concrete joint cleaning and filling machine (A) is brought onto the concrete work piece (1) with the joint gap formed. The front guide (7) and the rear guides (16) are adjusted according to the joint gap. The desired depth is formed by the base movement arm (15) and the taping width by the taping adjustment element (9.1). Paper tapes from the taping mechanism (9) are placed on the joint edges. Silicone wick from the wick mechanism (13) is placed on the area/joint to be cut over the concrete. The machine is operated from the control panel (5). The valve of the joint primer filler distributor (11.1) is opened. The cutter base (4) is lowered down with the base adjustment arm (15) and the cutting mechanism (8) starts to move within the previously cut joint space. While the wastes filled in the joint gap after cutting are removed with the cutting mechanism (8), the dust and pieces that come out are collected in the chamber (6.1) on the machine with the cleaning and vacuum mechanism (6). As a final operation, the fluid material is laid on the cavity the by means of the distributor (11.1) of the priming mechanism (11). In this way, the jointing process is carried out with a single machine without extra labour.

The scope of protection of this application has been determined in the claims section and cannot be limited to what is explained above definitely for exemplary purposes. It is clear that a person skilled in the art can demonstrate the innovation set forth in the invention by using similar embodiments and/or can apply this embodiment to other similar purposes used in the related art. Therefore, it is obvious that such constructions will lack the criteria of innovation and especially going beyond the state of the art.
