The present invention is a formwork panel used in construction, etc., a rectangular plate member having a plurality of coupling members such as bolts fixed to the back, and a frame having a plurality of through holes through each of the coupling members and the outside of the coupling member through the through holes Composed of a fastening member detachably coupled to the end, the plate and the frame is repeatedly detachably coupled to reduce the maintenance cost of the formwork panel by repeatedly detachable plate and frame. It is about formwork panels.

In the construction of various buildings and structures, the concrete wall is formed by forming a mold such as a mold in which the internal space forms the wall, that is, forming the mold first, and then filling and curing the concrete inside the formwork.

Thus, the formation of the wall begins with making the formwork, a mold for curing concrete.

As a conventional tool used to make the formwork as described above, conventionally, wooden formwork panel combined with a wooden frame on the back of the plywood has been mainly used, looking at the concrete wall forming process using the wood formwork panel as follows same.

A large number of wooden formwork panels made from nailed wooden frames on the back of plywood are connected to the outside of the rebar assembly, which is the skeleton of the wall or column, to form formwork for the interior, exterior walls, or columns, and then the concrete is placed in the space between them. It is filled and cured, and after curing is completed, the wooden formwork panels forming the formwork are removed from the wall.

By the way, when constructing the concrete wall using the wooden formwork panel, since the connection assembly between the formwork panels is made by nailing together with the tightening of the wire, the manpower and time are required for the formwork installation work, and also the formwork after concrete curing Demolition work takes a lot of time and manpower.

In addition, the wood formwork panel is easily deformed by the pressure of the concrete filled in the formwork due to the nature of the wood, and the larger the size of the wall, the more the tendency is increased, so that the outer surface of the wall does not form a flat surface Sometimes it happens.

Therefore, in order to prevent deformation of the wooden formwork panel as described above, in addition to the inconvenience of having to reinforce the back of the wooden formwork panel with a separate reinforcement before filling the formwork with concrete, the wooden formwork panel is However, the number of repeated reuses is extremely limited because they are often deformed or damaged during the installation and removal of formwork.

In addition, the damaged wooden formwork panel has been treated mainly through incineration, but recently, since the smoke generated during incineration acts as a pollution factor, it also points out a problem such as an additional cost for the treatment. It is becoming.

In order to solve the problems of the wooden formwork panel as described above, a metal formwork panel made of metal such as steel or aluminum alloy has been developed and used in various construction sites, and its use range and scale are rapidly increasing. There is a trend.

However, in the case of steel formwork panel, since the weight is considerable, there is a problem that the labor load can be excessively increased when the formwork is installed, and an aluminum alloy formwork panel has been developed to solve this problem.

Aluminum alloy formwork panels are not only lighter in weight than steel formwork panels, but also have a high self-rigidity, so that they are hardly deformed by concrete pressure compared to wood formwork panels, and thus the surface quality of the cured walls is excellent and Not only is it easy to install and dismantle, but it can also be reused repeatedly.

However, aluminum alloy formwork panels have a disadvantage in that manufacturing costs are higher than steel formwork panels.

In addition, the formwork panel, regardless of the material, the front surface is in close contact with the wall and the frame is coupled to the back of the plate, in the case of the conventional metal formwork panel, the plate and the frame is made integrally, or riveting It is fixed by the bar, in particular, when the damage to the plate close to the wall will not be able to use the die panel itself, such a problem is large in the case of a relatively low strength aluminum alloy formwork panel.

In addition, the surface quality of the wall may be degraded by the riveting marks remaining on the wall. In particular, in the case of the aluminum alloy formwork panel, since the rigidity and surface hardness of the aluminum alloy sheet are inferior to that of the steel sheet, the surface scratch resistance is insufficient. In addition, the riveting marks may not be formed on the surface of the wall, and in some cases, a separate synthetic resin coating layer may be coated on the surface of the aluminum alloy plate to improve the surface quality of the wall.

The present invention is devised to solve all the problems of the conventional metal formwork panel, and by freely separating and combining the plate and the frame, not only to reduce the maintenance cost of the formwork panel, It is an object of the present invention to provide a formwork panel that can be used by repeating the plate and frame of different materials as needed.

The object of the present invention is achieved by a plurality of coupling members fixedly coupled to the back of the plate.

Formwork panel that the plate and the frame of the present invention is repeatedly detachably coupled, has a structural feature that has a structure that can freely separate or combine the plate and frame whenever necessary.

The formwork panel of the present invention as described above, the plate member is coupled to a plurality of linear coupling members on the back; A frame having a plurality of through holes through which each of the coupling members passes; It consists of a tightening member and the like detachably coupled to the outer end of each coupling member penetrating through the through hole.

At this time, the material of the plate and the frame, regardless of the type of metal, such as steel (steel) or aluminum alloy, it is most economical and usability to use a steel sheet in the case of a plate and aluminum alloy in the case of the frame. desirable.

The reason why it is preferable to make a plate as a steel plate and a frame as an aluminum alloy as described above is because, in the case of a plate, a steel plate having a relatively high strength and hardness is used because scratches or deformations are likely to occur on the entire surface of the plate in close contact with concrete. However, by making the frame of the aluminum alloy frame, because the weight of the present invention formwork panel can be minimized.

Of course, the formwork panel of the present invention may be formed of a steel plate and a steel frame, an aluminum alloy plate and an aluminum alloy frame, an aluminum alloy plate and a steel frame, and in the case of a frame, a reinforced plastic may be used.

And, as a representative of the coupling member for joining the plate and the frame, the bolts such as ordinary bolts, stud bolts, etc., the fastening member may be a nut that is detachably coupled to the bolts, for example, a radial coupling The pin is provided with a ball as a coupling member, the wedge-shaped pin that is penetrated or inserted into the coupling hole may be used as a fastening member, various types of coupling member and a fastening member may be used as necessary.

In addition, it is preferable that the inner end of the metal coupling member fixedly coupled to the back of the metal plate is firmly attached by welding, so that the front flatness of the plate can be maintained by the welding joint of the plate and the coupling member during welding. In case of deformation in the welding process and the front surface of the opposite side of the joint, sheet metal, polishing, etc. should have flatness before deformation.

At this time, the coupling of the plate member and the coupling member does not necessarily have to be fixed, it may be combined in a detachable manner if necessary, and in the case of fixed coupling of the metal plate member and the metal coupling member, it is preferable to weld. General electric arc welding, stud welding, etc. are mentioned.
