Description

Technical Field [0001] The present invention relates to a support structure for a slab panel having a fixing clip,

The present invention relates to a new concept to prevent excessive noise and safety accidents in the process of slab panel disassembly after concrete curing by lowering a slab panel together when a support supporting a slab panel is lowered.

Construction of the structure using reinforced concrete is carried out in the order of installing concrete such as formwork and then installing the concrete.

In particular, slab construction for each layer of the structure is accomplished by placing the concrete together with the lower wall part. Therefore, at the time of construction of the slab, (n) a wall panel for a floor wall is provided on the front and rear surfaces of the wall, and (n + 1) layers are formed on the wall panels facing each other, After installing the slab panel horizontally, concrete for the wall and slab is poured and cured inside the wall panel and the slab panel, and then the wall panel and the slab panel are disassembled.

On the other hand, since the slab panel is supported by the wall panel, it is insufficient to support the load of concrete placed on the upper part. Therefore, as shown in FIG. 1, a support 30 and a support 40 are installed under the slab panel to share the load on the slab, and the support 40 and the wall panel 11 are disassembled when the slab panel is disassembled And the slab panel 22 is demolded (removed). In this process, after the support 40 is removed, the support base 30 is first lowered (first down) by a certain distance and then the slab panel 22 is lowered (second down) by its own weight. In this process, the slab panel 22 ) Causes a noise at the construction site and damages the slab panel 22 itself, thereby reducing the recycling rate of the construction material and accompanying the risk of safety accidents.
