Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a fast, non-destructive assembly and disassembly of a fully recyclable steel brace. Background Art

[0002] As a common support form, diagonal bracing is often used in foundation pit support projects. Reinforced concrete internal support beams are a transitional support system. When the project construction reaches a certain level, this temporary support system will be completely removed.

[0003] With the continuous development of deep foundation pit support technology, traditional and backward processes are increasingly being replaced by green, low-carbon, energy-saving and environmentally friendly new processes. In the construction of traditional deep foundation pit diagonal bracing, whether it is reinforced concrete diagonal bracing or steel diagonal bracing, it is usually necessary to cast concrete corbels at both ends of the foundation pit diagonal bracing, or weld steel corbels through pre-buried iron plates. The setting and removal of corbels are time-consuming and labor-intensive. The demolition of concrete corbels or the cutting and leveling of pre-buried iron plates will generate construction waste, which is less environmentally friendly; it will also have a certain impact on the subsequent floor pouring at the bottom plate.
