In general, in order to construct a wall by placing concrete, a method of using a formwork wall or a joining wall has been used, but the form wall is installed to face the formwork on both sides, and the form wall is maintained by a form tie, and the concrete is placed inside. It is a method of constructing walls, and a plywood wall is a method of constructing walls by pouring concrete by supporting the formwork to one side adjacent to the strata.

Forming the wall in the conventional manner as described above, the formwork is used, in the case of commonly used wood plywood formwork is produced by stacking a plurality of end plates, the resistance to bending loads compared to the thickness or weight is large, the transverse force Is excellent, but prolonged exposure to moisture, sunlight, or air is difficult to store and work due to bending, twisting and decay, and easily broken, so it is difficult to use more than 5 to 6 times, and it is impossible to recycle. There were many problems such as environmental pollution due to disposal and high construction cost due to increased material purchase cost.

In addition, the heavy weight of the wood itself is not easy to transport and install, and after curing the concrete, the formwork must be removed, and the plywood sticks to the concrete relatively well. The degree of surface damage in the process of removal after hardening is high, which reduces the quality of the concrete wall and further reduces the number of reusable formwork.

In order to make up for the shortcomings of such wood plywood formwork, construction sites with many repetitive constructions in the same plane such as apartments are used a lot of metal euroforms as wall formwork, and the euroforms are I-BAR or flat iron (FLAT). BAR) It is made of coated plywood that can be replaced with a frame.It is composed of Euroform ties and tie connecting pins as accessories, and it is used by removing old plywood and attaching new plywood after 10 times of use. It is easier to install and dismantle than plywood formwork, and is widely used because of its strength. In addition to metal euroforms, a panel molded with synthetic resin can be used as a formwork panel. Modified flow paths are also used.

However, Euroform also has a high material cost due to replacement of plywood, and it is impossible to recycle other than the basic size due to custom manufacturing.There is no data based on structural calculations or experiments due to inadequate research. B. There is no usage standard, and the weight is heavy, so it is not easy to transport and install, and when there is a torsion caused by multiple use, it is impossible to recover it by manpower. When disposing of the product at the end of its life, the problem of environmental pollution is serious. Eurofoam also has a problem that the surface damage is large in the process of removing after the hardening of the concrete, reducing the quality of the concrete wall.

In order to solve the above problems, the 'formwork panel assembly and the wall structure using the same,' and the 'formwork concrete panel' of the domestic registered utility model No. 20-322018, such as registered domestic patent No. 10-521647 When the concrete is cured after using as a formwork, the quality of the concrete wall is increased except for the process of removing the formwork by removing the panel without removing the panel, but the construction was inconvenient, maintaining high tightness between panels. The installed panels do not have high bearing capacity and do not guarantee the high strength of the concrete walls during or after curing.

Therefore, the present invention constitutes a prefabricated panel that is easy to transport and install, has a high tightness and supporting force between the panels, and constitutes a prefabricated panel for formwork that is easy to install, without removing the panel after use as a formwork, By using it as interior and exterior materials, it aims to shorten the construction period, reduce construction costs, and manufacture high quality concrete walls.
