Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a fixing structure for the side template of the door opening of a building construction machine. Background Technology

[0002] In the construction of high-rise buildings, when there are openings in the core tube structure during the pouring process, the sides and top of the structural openings need to be assembled using loose formwork. The traditional construction method for the construction of the bottom formwork of the upper beam is to use supports to hold it up under the bottom formwork of the beam. The fixing of the side formwork is relatively complicated. The construction using conventional bolt-locked formwork is time-consuming, labor-intensive and inefficient.

[0003] Therefore, the proposed method for fixing the side formwork of the doorway, which is efficient, fast, and easy to install, is of great significance. Utility Model Content

The large wall template and the door opening side template are locked and fixed together by a side-connected fixing structure. The fixing structure includes a long screw, a fixing pull plate threaded onto the long screw, and a locking cap for locking and limiting the fixing pull plate. A fixing seat is bolted to the side of the reinforcing beam of the large wall template. The long screw passes through the waler on the side of the door opening side template and engages with the threaded sleeve on the fixing seat.
