Description

A telescopic wellbore platform support

technical field

The utility model relates to the field of building climbing frames, in particular to a telescopic shaft platform support.

Background technique

Shaft platforms are mainly used for concrete pouring of shaft structures such as elevator shafts, equipment shafts, and stairwells in high-rise buildings. The lateral pressure of the concrete is mainly borne by the through-wall screw, which is simple, fast and economical to use. The support part of the group forming the wellbore platform is the lower bracket. In the general construction process, threaded holes are usually set at both ends of the bracket, and then through the two The bolts on the walls and the threaded holes are respectively threaded to fix the bracket, and finally the wellbore platform is fixed. However, in the traditional way, because the distance between the walls is not fixed, it is usually necessary to measure the distance between the walls on site. Then, the length of the stent can be determined, and then the stent can be cut on site, and new holes are drilled, which is time-consuming and labor-intensive. Therefore, a stent is urgently needed to solve the existing problem.
