Abstract

The invention provides an axial force grouping and regulating method for a steel support structure. The method is applied to the steel support structure in foundation pit engineering, and steel supports of the steel support structure are used for supporting an enclosure in the foundation pit engineering. The regulating method comprises the steps that the steel supports in the steel support structure are grouped, wherein the steel supports with the same axial force are in one group; axial force regulating is conducted on the steel supports in the group simultaneously. According to the axial force grouping and regulating method for the steel support structure, a plurality of steel supports with the same axial force are in one group and are regulated synchronously, therefore, the regulating efficiency of the steel supports can be greatly improved, and the human cost can be reduced; in addition, power can be uniformly supplied to the steel supports in the same group through one power source, and therefore the equipment investment and the construction cost can be reduced.

Description

technical field [0001] The invention belongs to the field of building construction and relates to an axial force grouping control method of a steel support structure. Background technique [0002] At present, in building construction, reinforced concrete is used as the horizontal support in the pit for large-scale underground excavation, but this method has high construction costs and cannot be reused, especially after the construction is completed. The demolition workload is heavy, the noise is large, and the pollution is serious , is not conducive to environmental protection. At present, another method is to use steel support as the horizontal support after underground excavation to resist deformation of the foundation pit. It overcomes the shortcomings of concrete horizontal support and has the advantages of being reusable and environmentally friendly. [0003] At present, large-scale foundation pits mostly use two-way steel support structures. The method is to apply loa...
