Description

  The present invention relates to a plastic temporary frame for RC concrete houses.

  When placing concrete in RC concrete houses, wooden temporary frames are still used today, and temporary frames are manufactured by hitting piers on wooden plywood. However, this work for assembling the temporary frame requires a lot of labor and time, and it takes a lot of time for the temporary frame work in the entire work, which greatly affects the entire construction period. In addition, the wooden temporary frame once used has a hole in the separator, and when it is dismantled, the pier is easy to hurt. It was desired to improve the problem. Furthermore, wooden temporary frames have been a problem from the viewpoint of protecting forest resources.

  Under these circumstances, in order to solve the problems up to now, a temporary frame made of plastic has been devised and is already on the market and used in the field.

  Compared to conventional wooden temporary frames, this temporary frame made of plastic is processed repeatedly to match the size of the slats, making it unnecessary to assemble, and it is durable and should be used repeatedly. In addition, it is possible to collect cut ends and recycle them again, which can contribute to natural destruction and environmental protection.

Problems to be solved by the invention

  However, as shown in FIGS. 10 and 11, the conventional temporary frames made of plastic are made on the assumption that they are used in a standard size (for example, 600 mm × 1200 mm). Therefore, it is necessary to prepare many types of temporary frames of different sizes depending on the parts to be used. For this purpose, a large warehouse for storing and storing plastic temporary frames and many expensive molds are required. Met.

  Furthermore, the temporary frame made of plastic as a raw material becomes heavy because the frame body and the plurality of reinforcing ribs are integrally formed at a predetermined interval, and the work efficiency is poor in terms of transportation and handling in the building. There was a problem of becoming.

  The present invention has been made in order to solve the conventional drawbacks as described above, and the problem is that by making a plastic temporary frame by extrusion molding, according to the required height of the temporary frame. Because it becomes possible to cut and manufacture the plastic temporary frame to the required length, it is not necessary to prepare many expensive molds, and the rib for reinforcing the temporary frame body and the temporary frame body Are manufactured separately and assembled at the site, so that it is easy to carry, and an inexpensive and easy-to-assemble plastic temporary frame is provided.

Means for solving the problem

In order to achieve such a subject, the invention according to claim 1 is a temporary frame structure of an RC concrete house, wherein the surface of the temporary frame in contact with the concrete is constituted by a plane, and the convex reinforcement is provided on the back surface of the surface in contact with the concrete. As for the part which forms a part and fixes with the side surface of an adjacent temporary frame, one side is shape | molded in U shape, and the other is L-shaped L-shaped part, and supports a horizontal fixed support material in the L-shaped part. Both ends are used to engage with the engagement holes on the side surfaces of the extruded plastic temporary frame, and use the extrusion molded plastic temporary frame with a fixing hole for joining with the L-shaped steel material. Molded in a square rod shape, one square rod shape is formed with an engagement recess to engage the U-shape molded in an extruded plastic temporary frame, and the square rod shape at both ends has an extruded plastic temporary frame Holes for fixing are made so that they do not fall off, the middle part supports the square rods at both ends, and is molded with injection molded plastic with an H-shaped cross section so as to contact the convex reinforcing part of the extruded plastic temporary frame The adjacent extruded plastic temporary frames are fixed to each other with the horizontally fixed supporting member, and the abutting surface of the L-shaped part on the back side of the surface of the extruded plastic temporary frame that contacts the concrete, and the L-shaped steel material are fixed with a fixing bracket. It is characterized by being fixed.

Effect of the invention

According to the first aspect of the present invention, in the temporary frame structure of the RC concrete house, the surface of the temporary frame that is in contact with the concrete is configured by a plane, and the convex reinforcing portion is formed on the back surface of the surface that is in contact with the concrete. The side of the fitting temporary frame and the part to be fixed are molded in a U-shape, the other is formed in an L-shaped L-shaped portion, and the L-shaped portion has an engagement hole for supporting a horizontal fixing support material, While using an extruded plastic temporary frame with a fixing hole for joining with the L-shaped steel material, both ends are formed in a square bar shape so as to engage with the engagement hole on the side surface of the extruded plastic temporary frame, One square bar shape is configured with an engagement recess to engage the U-shape formed on the extruded plastic temporary frame, and the square bar shape at both ends is fixed so as not to fall off the extruded plastic temporary frame. A fixed hole is drilled, the middle part supports the square rods at both ends, and the horizontal fixed support is molded in injection-molded plastic with an H-shaped cross section so as to contact the convex reinforcing part of the extruded plastic temporary frame By fixing the extruded plastic temporary frames adjacent to each other with the material, and further fixing the L-shaped steel material with the abutting surface of the L-shaped part of the back surface of the extruded plastic temporary frame in contact with the concrete , In the past, plastic temporary frames were injection-molded, and all were made on the assumption that they would be used in a standard size. Therefore, not only did many expensive molds be required, but plastic temporary frames were stored and placed. For those who needed a large warehouse, the use of an extruded plastic temporary frame for the concrete surface temporary frame made it possible to use only one extrusion mold, and many expensive Since a mold is not required, the concrete surface temporary frame can be manufactured at a low cost, and the concrete surface temporary frame and the reinforcing material supporting it are separately configured for transportation and temporary frame assembly. Can be facilitated, and the cost can be greatly reduced.
