Description

Construction support pipes {A SUPPROT PIPE FOR CONSTRUCTION}

The present invention relates to a support pipe for building, and in particular, by using a support pipe composed of a combination of upper and lower support members and a lower support member, a gap retaining zone for maintaining a space between the support pipes of the front and rear and left and right, It prevents torsion to obtain a structure with high precision, and improves workability and shortens working air accordingly.

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

The support pipe supports the formwork pre-installed before placing concrete to maintain a uniform height, thereby preventing local collapse of the concrete to be poured to the top to prevent collapse and curing the poured concrete. The main function is to prevent the deformation from occurring until now.

The support pipe is usually provided with a lower support member placed in a substantially vertical form on top of a bottom slab, an upper support member placed in a form supporting a lower portion of a ceiling slab, and an upper and a lower portion between the lower support member and the upper support member. It is composed of a height adjustment unit coupled to be moved in the vertical direction and a stop pin to prevent the upper support member is moved to the bottom.

The process of installing the support pipe 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 to raise it, then rotating the height adjusting part and simultaneously pushing up the stop pin fitted to the upper support member. As a result, the upper support member connected thereto moves upward.

Therefore, as the upper support member and the lower support member maintain the shape of pushing down the lower part of the ceiling slab, the weight of the concrete generated in the process of placing the concrete stably supports and prevents accidents such as collapse. Deformation is prevented in the process of curing the poured concrete.

However, the support pipes should ideally be installed at regular intervals so that they can support the load of the concrete being poured while preventing the risk of collapse and preventing deformation from occurring during curing. Due to the narrowness of the work space and the lack of recognition of the workers, there is a problem that the work air is lengthened by lowering the precision and workability of the structure due to the torsion in the formwork (form).

The present invention was created in order to solve such a problem, and by using a support pipe composed of upper and lower support members and a lower support member in combination with a gap retaining hole for maintaining a gap between the support pipes of the front and rear and left and right sides, It is an object of the present invention to provide a support pipe for building to prevent twisting to obtain a structure with high precision, and to improve workability and shorten working air.
