Description

Supporting structure for concrete wall

The present invention relates to a concrete plywood support, and more particularly, when fixing the formwork for supporting the concrete plywood by the support, provides compatibility in the combination of the formwork and the support and provides an easy working environment.

In general, in the case of a multi-storey building, after reinforcing bars are laid on the ground floor, the concrete floor is constructed, and then the formwork is built vertically or horizontally on the floor to repeat cement filling to build a building. .

The pouring of the wall is constructed in a manner called butt wall or plywood, and the butt wall refers to a method of placing concrete between the formwork by placing the formwork on both sides of the excavated underground space.

And, the plywood wall is one side is supported by the excavated underground strata, the other side is fixed by installing the formwork fixed by the support, and refers to the method of pouring concrete, and the process is simpler than the plywood method is short-term It has an advantage that can be performed.

In order to construct the concrete plywood, a form support method using a washer and a wing nut is conventionally used by welding a form tie to an H-beam pile embedded in the ground to fix and support the formwork.

However, since the form tie is buried in the concrete wall, it cannot be completely waterproofed after construction, and the form tie supporting the formwork must be welded and attached to the form wall, and a hole corresponding to the formwork must be drilled. Occurs.

In order to improve this, after installing the formwork, a triangular truss-shaped support is installed and an anchor is installed at the bottom to fix the support, but the manufacturing cost is expensive and above all, when the formwork and the support are combined, Only the formwork that fits the support can be used, causing compatibility problems.

In addition, when a large amount of pressure is applied to the support, deformation may occur, and when the thickness of the pipe used for the support is thickened to prevent deformation, transportation costs may increase along with an increase in material cost.

An object of the present invention for solving the above-mentioned conventional problems is to provide a concrete cladding wall support having compatibility according to the type of formwork, and having an easy mounting structure.

In addition, there is an increased rigidity without increasing the thickness of the pipe, and to provide a concrete cladding support applicable to various mounting situations.
