The present invention relates to a space maintenance device for a building support, and in particular, by installing the connecting rod is coupled between the hanger fixed to each unit support consisting of a combination of the upper support member, the lower support member and the height adjustment mechanism, It prevents falling and twisting of the support supporting the formwork and prevents it from falling through the role of distributing vertical load and lateral load so that safety can be maintained and construction work can be shortened accordingly to improve workability. .

In order to cure concrete at the site of civil engineering or building structures, support is usually used to support the lower part of the concrete structure until curing is completed.

This support supports the preformed formwork to be leveled at a uniform height before placing the concrete, preventing local collapse of the concrete being poured to the top and preventing it from collapsing. The deformation is prevented from occurring.

The support is vertically disposed between the lower support member which is usually placed in a form substantially perpendicular to the upper portion of the bottom slab, the upper support member which is placed in a form supporting the lower portion of the ceiling slab, and the lower support member and the upper support member. It is composed of a height adjustment unit coupled to be moved in the direction and the stop pin to prevent the upper support member is moved to the lower side.

The process of installing the support having such a configuration between the floor slab and the ceiling slab is performed by first inserting the upper support member into the lower support member, then raising the height adjusting part and rotating the height adjusting part, and simultaneously adjusting the stop pin fitted to the upper support member. As it is pushed up, the upper support member connected thereto is moved.

Therefore, as the upper support member and the lower support member maintain the shape of pushing up the lower part of the ceiling slab, it stably supports the weight of concrete generated in the process of placing concrete, thereby preventing safety accidents such as collapse. In addition, it prevents deformation during curing of the poured concrete.

However, it is ideal for the support to be installed at regular intervals so that the support can stably support the load of the concrete being poured and to prevent the risk of collapse and to prevent deformation from occurring during curing. If the spacing is not constant due to the narrowness of the worker and the worker's lack of recognition, there is a problem that the work air is lengthened by decreasing the precision and workability of the structure due to the twisting of the formwork.

The present invention has been made to solve such a problem to prevent the twisting of the formwork to obtain a structure with high precision, and also to improve the workability and construction of the gap support device for building support that can shorten the work air accordingly The purpose is to provide.

In order to achieve the above object, the present invention provides a unit support (A) in which the upper support member (3) and the lower support member (4) are coupled by the height adjusting device (5) in the space maintaining apparatus of the building support. The hanger 1 is configured to be coupled to the lower support member 4 of the unit support A, and the other hanger 1 'is coupled to the other unit support A'. It is characterized in that it is configured so that the connecting table (2) is installed between the hanger (1) and the other hanger (1 ').
