Description:

A Panel Mould for Casting Concrete

Technical Field of the Invention

The present invention relates to a panel mould for casting concrete, more particularly the structures of panel mould.

Background of the Invention

The conventional timber or metal form panel of concrete mould is common. A product of the wood related industry such as plywood is heavily used as a material to make concrete moulds for construction industry. For resources protection, it becomes difficult to receive timber and it is becoming a high cost recently. Although excelled in endurance at the metal form, it is very heavy and was hard to treat and cost was also high.

It is also known that the form panel from plastics was also developed as what is replaced with these timbers or metals to provide lightweight, long working life and economical. The prior disclosure in JP10025930, shown that the mounting section of the ends panel for fitting them at the surface of panel was carried out that required the accessories such as nails, screws and bolts to hold the panels together. Further, there is added structure as plastic joiner or connection piece as shown in JP2000240283 has been used for connecting and fitting the panels together which also to prevent the slug of the concrete thoroughly from the between of panels.

A problem with the above known is that the connection having such cannot make panels connection easily or on the spot. The process of panels assembly is needed a large labour intensity and addition means such as nails or screws. It is also required careful works to prevent the panels from damage during disassembly.

It is an object of the present invention to provide a panel in which the above problem is reduced or minimized.

Disclosure of the Invention

According to the present invention, there is provided a panel mould for casting concrete comprising: a panel body which includes a plurality of side walls to form the boundary of the body for assembling the panels, a rear face which is substantially a flat surface for facing the pouring concrete and a front face reinforced by rib for supporting the panel, a positioning means formed at the exterior of side walls for preventing the concrete slug thoroughly from the assembled panels, characterized in that the side walls comprise a connection means for connecting at least two of the panels in positioned and a locking means for locking at least two of the panels in connected.

The connection means and the locking means are substantially acting together by same direction of the force to ensure the panels are assembled completely. Thus the prior art problems is reduced.

The connection means is preferably at least one pair of a hole and a knob which are located in a line to one another at the two opposing side walls wherein the knob having a chamfered head for easily inserting into the hole during the process of assembly the panels. Also, it is preferred that the locking means is comprised at least one pair of a T-hole and a catch which are located in a line to one another at the two opposing side walls wherein having a latch for latching tightly into the T-hole.

A further object of the invention is to provide a panel mould for casting concrete, as described in the preceding paragraph, a positioning means comprises two pair of a groove and a tongue which are located in perpendicular to one another and formed along the centerline of the side walls for positioning the panels in assembly process.

It will appreciate form the foregoing that the present invention provides at least two panels are assembled and disassembled. The panels are made from resilient plastic material by inj ection process.

Description of the Preferred Embodiments

The constmction method uses plastic panel of mould that attachable and detachable to form a building structure of various shapes such as column, beam or ceiling for pouring of cement grout. Referring now to the figures, it can be seen from FIG.l and FIG.2 that the panel is generally a rectangular shape or square shape or any other suitable shapes, comprising a body 11 formed of a generally plastic resilient material. The body 11 has side walls 2 that are formed a boundary around it periphery. A front face 3 of the panel is reinforced by a rib 5 for supporting the body panel and made it hard to hold a high load or weight of the pouring concrete. The rib 5 may structured of a generally vertical or horizontal or both that is connected the side walls 2, it is preferred in both that formed a rectangular or square rib box being capable to support the high load. The rear face 4 of the panel is smooth surface so that after disassembled of the panels, concrete casts had been a linear or clear surface of building structures. It is also, could accurate the edges of structure shape.

In FIG.3 to FIG.5 are illustrated an extending from the side walls 2 is the positioning means 6 for positioning at least two of the panels beside one another and the two side walls 2 in perpendicular to one another of the body panel is a tongue 22. The shape of the tongue may form in rectangular, triangle or circular. It is preferred a semi circular shaped tongue 22 which is projected out from the side walls 2a, 2c as illustrated in view A and C of FIG.4. The other two side walls 2b, 2d in perpendicular to one another of the body panel comprises a groove 21 is projected into the side walls as illustrated in views B and D. The shape of groove 21 shall corresponding to the tongue 22 shape for match-fit which is easily for positioning one side wall of panel with another side wall of panels.

The side walls 2 of the panel are also provided with connection means 13. The connection means 13 includes at least one knob 32 extended from the side wall 2a with an outside decline shape from the top to half of knob. This portion is a chamfered head 33 that formed to facilitate in connecting the panel with another panels during the assembly. At least one corresponding hole 31 is formed at the opposing side wall 2b which is aligned to the knob 32, for accepting the knob 32 from another panel. The both knob 32 and hole 31 are substantial located in a line to one another at the two apposing side walls 2a, 2b. Further, another two opposing side walls 2c, 2d are provided with locking means 14 for locking at least two assembled panels. A catch 42 is extended from the side wall 2c with a latch is projected portion for latching the assembled panels securely and tightly. At the opposing side wall 2d in a line to the catch 42, a T-hole 41 is formed for accepting the catch 42 from other panels. Both the catch 42 and the T-hole 41 are substantial located in a line to one another at the apposing side walls 2c, 2d.

In practical use, the panel X would be assembled with the panels Y and Z by positioning the tongue 22 at side walls of panel X into the groove 21 at one side wall of panel Y and panel Z as illustrated in FIG.5. When the tongue 22 is positioned near to the groove 21, the catch 42 of panel X is inserted into the T-hole 41 of panel Z and at the same time, the knob 32 of the panel X is positioned closely to the hole 31 of panel Y. The chamfered head 33 of knob 32 engages the lip of hole 31. At this moment, the panel X is improperly connected with the panels Y and Z. The sufficient force is applied to insert the knob 32 into the hole 31 for completing the connection of the panel X to the panel Y. Simultaneously, the catch 42 of panels X is also moved in similar direction of applied force whereby the latch 43 is latched at the bottom of T-hole 41 for locking the panel X to the panel Z. The arrows in FIG.5 illustrate the process of panels mould assembled above. Durability and strength of panel mould is

further enhanced by assuring a cross cutting inner linings of varying angles. As well, it is preferred the several holes 51 are designed for vertical and horizontal insertion of steel rod 52 as reinforcement. In the construction side, the complete panels mould 60 assembled illustrates in FIG.6, the cement mixtures 61 are poured into that plastic mould and on hardening, the panels mould are then dismantled and the panel is recycled for further applications.

The embodiments illustrated in the drawings will be readily apparent to the skilled man that numerous modifications and alterations may made to the illustrated panels for moulding concrete without departing from the principles underlying the present invention. All such modification and alteration are intended to be embrace by scope of this invention, which is limited only by scope of the appended claims.
