Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an installation node for cantilevered steel formwork of composite beam flange plate. Background Technology

[0002] Under normal circumstances, the formwork for the flange slab of composite beams is constructed using a cantilevered double-channel steel structure. The principle is to suspend the double-channel steel and timber formwork using tie bolts. This cantilevered construction method involves the use of double-channel steel. During on-site construction, the following three situations may arise:

[0003] 1) During the construction of timber formwork, the timber has relatively low hardness, and the timber formwork is easily damaged by external forces during construction, which can easily lead to quality defects in the concrete and poor appearance quality of the concrete after the cantilever flange plate is poured.

[0004] 2) In general construction sites, the cantilevered part of the composite beam is constructed using double-channel steel, timber, and wooden formwork. The wooden formwork has a low reuse rate, and it is difficult to reuse it after it is damaged, resulting in material waste.

[0005] 3) The cantilevered part of the composite beam is constructed using double-layered channel steel, timber, and wooden formwork. The formwork installation process is complicated and the construction efficiency is slow. Utility Model Content

[0010] Preferably, the composite beam has multiple embedded parts for fixing and installing the cantilever steel structure.

[0011] Preferably, each of the embedded parts includes multiple connecting rods pre-embedded in the composite beam, and a second ear plate is correspondingly installed at the bottom of the cantilever steel structure for fixing the multiple connecting rods together.

[0012] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0013] It is easy to source materials, simple to manufacture, convenient to use, and has a high utilization rate. It can be disassembled and reused repeatedly, which is in line with the concept of green construction. It can greatly improve the quality of concrete pouring for cantilever flanges of composite beams, which is in line with the concept of high-quality construction. Attached Figure Description
