Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an early-stripping support head that allows for the early removal and reuse of main beams in buildings. Background Technology

[0002] Early-stripping support heads, which enable the early removal and reuse of main beams in construction, are a type of construction tool. They improve the efficiency of formwork use, shorten the construction cycle, reduce costs, and increase economic benefits. The early-stripping support head is detachably and fixedly connected to the aluminum main beam, allowing for rapid assembly and disassembly of the aluminum main beam and convenient use. However, existing early-stripping support heads, such as the one disclosed in utility model patent CN213268891U, which allows for the early removal and reuse of building formwork, do not securely fasten the aluminum main beam. This allows the aluminum main beam to easily detach from the support base, potentially causing injury to workers if it falls, posing a safety hazard and hindering mass production. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide an early dismantling support head that allows the main beams of buildings to be dismantled and reused in advance.

[0004] This utility model is achieved through the following technical solution:
