Description

Synthetic resin joist for formwork {construction material, made of synthetic reins, for a mold}

The present invention relates to a joist made of synthetic resin for formwork, and forms an octagonal composite horn having internal connection holes using waste synthetic resin such as durable polyethylene, and is inserted and fixed to the joint plate to prevent rotation. It is to provide a form made of synthetic resin joists to be connected to the desired length by having a connection member provided with a rotation preventing insertion port.

In the case of wood products that have been commonly used as construction and industrial materials in the past, the cross-force is excellent, but since water penetrates into the wood due to rain or other causes, it is impossible to perform underwater work, and corners are easily broken. There is a problem that is difficult to use more than 5-6 times.

In addition, wood products are released immediately when they are sanctioned, but if they are exposed to sunlight and air, they can be burned or twisted and disposed of immediately. This is a great burden for material purchase costs. Due to the chemicals used, serious environmental pollution problems are caused, and forest resources are gradually depleted due to the increased use of wood, which causes further environmental problems.

In addition, the wood products take a lot of time to process the process of trimming and manufacturing, while the use of the formwork joists are irregularly cut material costs a lot of problems, the weight of the wood itself is not easy to transport and install, There was a defect that the number of times of repeated use was largely limited because the surface was damaged in the process of detaching after formwork assembly.

On the other hand, products that are used as formwork joists on the market lack compatibility because each product's standard is not constant, which increases the inconvenience of concrete molding and work, and in order to prevent this, a single product must be purchased at the time of purchase. There is a problem that is expensive to purchase.

The present invention solves the problems of the wood products used for the conventional formwork as described above, the injection molding and molding of a durable synthetic resin, such as durable polyethylene is provided with an internal connection through hole, the same standard as the conventional general steel pipe By forming an octagonal composite shell material, it provides a product that is resistant to moisture and does not rot, and is provided with a connection member provided with an octagonal anti-rotation insertion hole which is inserted and fixed to prevent rotation on the joint plate so that it can be connected and used as desired. In addition, the end is provided with a closing member, the purpose of providing a synthetic resin joist for formwork that can also be used as an internal and external scaffolding material without a joint trace of each connection.

In addition, it is excellent in compatibility with existing products, and can be used simultaneously with other existing products such as wood panel, flow panel, euro foam, foam, etc. do.

The present invention relates to a sheet-shaped synthetic resin joist, injecting and molding a durable synthetic resin, such as polyethylene, to form an octagonal composite horn having internal connection holes, and is inserted and fixed to prevent rotation in the joint plate It is characterized in that it has a connection member provided with an anti-rotation insertion hole of the octagon to be connected and used as desired length.

The configuration of the present invention can be largely divided into three parts of the synthetic lumber 10, the connecting member 11, the finishing member 12, and will be described in detail with reference to the entire perspective view shown in FIG.

First, in the case of the synthetic keratin 10 in the present invention, it is formed to have an octagonal cross section with the same standard as the existing circular steel pipe using waste synthetic resin, such as durable polyethylene, in the longitudinal direction therein A connecting through hole 10a having a long penetrating and having an octagonal cross section is provided.

And, if necessary, the connecting member 11 is provided in order to be able to continue using the octagonal composite lumber 10 to the required length, the connecting member 11 is the same size and shape as the synthetic lumber 10. By forming the octagonal anti-rotation insert (11a) formed to protrude to both sides of the thin joint plate (11b) of the anti-rotation insertion hole (11a) is inserted into the inner octagonal connecting through hole (10a) of the composite shell material (10a) , Synthetic lumber 10 is coupled to both sides of the connecting member 11, as shown in FIG.

At this time, the coupling of the connection hole (10a) and the rotation preventing insertion hole (11a) of the connecting member 11 of the synthetic lumber 10 is formed by an octagonal shape rather than a circular shape, the synthetic lumber (10) By preventing the joint plate 11b from coming into contact with each other, it is possible to continue using it by the required length without any trace of the joint.

And, as described above, at the last end of the octagonal composite lumber 10 continued by the required length by the connecting member 11, the insertion fixture 12a only on one side on the same octagonal plate as the joint plate 11b of the connecting member 11 ) Is provided with a finishing member 12 is coupled to the connecting through hole (10a) of the shortest synthetic horn timber (10).

Forming synthetic resin joists of the present invention having the configuration as described above, is used to connect and support the formwork panels to form the formwork for concrete pouring, and to maintain the gap between the formwork panels, shown in Figure 3 Looking at the state of use through the form assembly example, by forming a formwork panel according to the form to be poured, and supported by the wood lumber, etc., by combining with the joist of the present invention as another substitute or steel pipe substitute In this case, the synthetic keratin of the present invention is excellent compatibility with other existing products can be used together, in addition to it can be used as a construction scaffold.

The present invention is manufactured by injection and molding waste synthetic resin such as durable polyethylene, which is strong against moisture, does not rot or rot. It can be used, so that the amount of overlapping or use of the member can be reduced.

In addition, the present invention does not absorb moisture, so there is no self-buoyancy, so it is easy to work underwater, and it is easy to work because it is light in weight, and it can be produced freely regardless of a certain standard. It has excellent compatibility and can be used in place of steel pipes because it is composed of the same standard as the existing round steel pipes, and can be used simultaneously with other existing products such as wood panels, flow panels, euroforms, and foams. Lightweight and easy to work

In addition, there is no need for a separate packing paper for material yards, and there is no maintenance cost.With the elasticity of the product, there is no need to use separate parts when assembling curved and straight formwork, and the environment due to logging and incineration for wood products It can solve the problem and reduce the cost of wood imports.
