Description

Plastic formwork {reinforced plastic form}

The present invention relates to a plastic formwork made of a synthetic resin material, and more particularly, to a plastic formwork having a configuration in which a reinforcing mold injection molded into an interior of an outer mold cut into a certain length by injection molding into a rectangular cross-section is formed.

In constructing buildings, internal and external walls, columns, beams, etc., are molded by placing formwork after reinforcement and pouring concrete to cure.

The formwork used to cast concrete is used in various forms in the field, but in general, formwork standardized to a certain standard is used. The formwork is composed of a steel frame having a waterproof plate therein, and the steel frame must be able to be connected to other steel frames adjacent to each other through pipes, wedges, foam ties, etc., so that the wedge ball has a tie groove formed at the edge thereof. Doing.

Formwork of the above-described configuration has a disadvantage in that the weight is heavy by the steel frame gives a field worker a difficult handling. For this reason, the weight reduction formwork has tried to put some plastic formwork to practical use.

Plastic formwork has the advantage of being lighter in weight than steel frame formwork, and especially easy to dismantle because it is easily separated from the cured concrete due to its own water repellency and inherent elasticity. It shows the problem of bending.

In order to solve the above problems, Korean Patent Nos. 469849 and 492221 replace iron frames with synthetic resin frames, and waterproof plates are formed by forming metal reinforcement panels having a network structure inside, and synthetic resin frames. It proposes a formwork formed so that the metal reinforcement panel of the network structure is also located inside, to sufficiently support the problem of plastic formwork, that is, concrete load.

However, reinforcing the weaknesses of plastics with metal reinforcement panels can support concrete loads but does not provide the structural robustness required for the building site.

In more detail, in the plastic formwork reinforced with the structure, the metal reinforcement panel includes a cross-linked portion at the edge of the frame, which is caused by dropping, hitting, and local concentration of loads at the construction site. If a strong external shock is easily shifted, there is a problem of damage to the formwork itself.

The problem that the corner part of the formwork is vulnerable to external impact is common in plastic formwork produced by insert injection, and some types of plastic formwork solve the local weakness by giving a reinforcement structure to the corner part. The effect is to be given to a considerable thickness, and increasing the thickness has a disadvantage that the weight of the form becomes heavy, which makes it difficult to handle in the field.
