Building foundation pit steel support structure

Abstract

The invention discloses a steel support structure of a building foundation pit. By the adoption of the steel support structure of the building foundation pit, the defects that according to an existing foundation pit support structure, since support replacement is needed in the construction process, the number of construction steps is increased, the construction cost is increased, and the construction progress is affected to a certain extent; and in addition, since overload of a steel pipe support cannot be found in time, the steel pipe support is prone to deformation and unstable supporting, even foundation pit collapse accidents are caused, and serious consequences are caused are overcome. The steel support structure of the building foundation pit comprises a supporting pipe and supports which are connected to the two ends of the supporting pipe. End plates are arranged at the ends, connected with the supporting pipe, of the supports. The end plates are detachably connected with the supporting pipe. Embedded plates are arranged at the other ends of the support. The embedded plates are connected to the inner wall of the foundation pit in a supported mode. Annular adjustment pads and shrinkage rings are installed between the end plates and the supporting pipe. The shrinkage rings are each of a hollow structure. Colorful powder and high-pressure released gas with odor are contained in the shrinkage rings. The inner wall and the outer wall of each shrinkage ring are each of a corrugated pipe structure.

Description

technical field [0001] The invention relates to a foundation pit supporting technology, more specifically, it relates to a construction foundation pit steel support structure which is convenient for construction. Background technique [0002] At present, the foundation pit of a building or structure needs to be supported before excavation, and it is generally supported by 609 steel pipes, and the steel pipe supports include corner braces and straight braces. When the foundation pit is excavated to the end, the wall body of the foundation pit needs to be built up, and when the support position is reached, the support needs to be removed, so as to continue to build the foundation pit wall upwards. At this time, it is necessary to install a temporary support under the support, which is called "replacement support" in architecture. This construction method of changing braces increases the construction steps and construction costs, and affects the construction progress to a cert...

Problems solved by technology

[0004] The present invention overcomes the fact that the support structure of the existing foundation pit needs to be replaced during the construction process, which increases the construction steps and construction costs, affects the construction progress to a certain extent, and can not be found in time when the steel pipe support is overloaded, and the steel pipe support is prone to appear Deformation and support instability, and even cause foundation pit collapse accidents, resulting in serious consequences, provides a steel support structure for building foundation pits, which does not need to be replaced during the construction process, eliminating the need to replace the construction steps, reducing the The construction cost is reduced, the construction progress is guaranteed, and when the steel pipe support is overloaded, it can be found in time to deal with it quickly, prevent the deformation of the steel pipe support and the instability of the support, and avoid the collapse of the foundation pit.
