Description

SUPPORT FOR CONSTRUCTION

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a construction support, and more particularly, to a construction support as a foundation for supporting a formwork.

In order to cure concrete at the site where civil engineering and structures are built, usually, a support that supports the lower portion of the concrete structure is used until curing of the concrete structure is completed.

This support supports the formwork, which is previously constructed before placing the concrete, so that it is leveled at a uniform height so as to prevent the concrete from being collapsed by blocking the local load of the concrete laid on the upper part, Thereby preventing deformation from occurring.

A typical construction support comprises a cylindrical lower pipe and a cylindrical upper pipe inserted in the upper part of the lower pipe, a long hole is formed in the upper part of the lower pipe, and a plurality of pin insertion holes are formed in the upper pipe in the longitudinal direction , The length of the upper pipe relative to the lower pipe is adjusted, and then the fixing pin is inserted into one of the plurality of pin insertion holes through the slot to be fixed.

However, in the conventional construction support, the length of the lower pipe and the upper pipe is adjusted, and then, in order to fix the fixing pin, the upper pipe is rotated with respect to the lower pipe so that the pin insertion hole of the upper pipe matches the slot of the lower pipe. And the upper pipe must be raised or lowered relative to the lower pipe, so that the work is difficult and time-consuming, which is a time-consuming operation.

Further, it is not easy to insert the pin at a time in a state where the pin insertion hole of the upper pipe and the slot of the lower pipe coincide with each other.
