Description

Technical Field

[0001] The utility model belongs to the technical field of steel support system connection, and in particular relates to a new type of fastener suitable for a steel support system. Background Art

[0002] The internal support system of deep foundation pits is mainly concrete support and steel support. Concrete support has the advantages of flexible arrangement, clear force, good deformation control ability, and does not occupy space outside the land red line. However, concrete support steel bars and concrete are not recyclable, resulting in material waste and a large amount of construction waste; the maintenance cycle is long, and it is necessary to reach a certain strength before continuing to dig downwards; there are many lattice columns and small excavation space, which affects the excavation progress. At the same time, deep foundation pit projects are often located in urban areas, and the removal of concrete supports will generate a lot of noise and dust, which has a serious impact on the surrounding areas.

[0003] Compared with concrete support, the steel support system has obvious advantages such as most of the steel components can be recycled, the column spacing is large, the excavation space is large, there is no construction waste, there is no noise on the construction site, and it is green and environmentally friendly. However, the steel support system is composed of several support components. If the span of the foundation pit is large, the stability and integrity of the steel support are lower than that of the concrete support. In the common steel support system, it is mainly in the form of a braced truss and a gantry, and there is no good way to fix the support truss and the gantry, which affects the stability and safety of the steel support.
