A dynamic control system and dynamic control method for a two-way steel support structure

Abstract

The invention provides a dynamic regulation and control system for a bidirectional steel supporting structure. The dynamic regulation and control system for the bidirectional steel supporting structure comprises the bidirectional steel supporting structure, axial force loading tools and a control center. The bidirectional steel supporting structure comprises flexible joints which are located at junctions of horizontal supports and vertical supports. Each flexible joint comprises an outer box, an inner box, a first connecting assembly and a second connecting assembly, wherein a first hole and a second hole coaxial with the first hole are formed in the surface of the outer box, and the inner box is arranged in the outer box; the first connecting assembly and the second connecting assembly penetrate through the first hole and the second hole correspondingly to be connected with the inner box; and elastic elements are arranged between the outer wall of the inner box and the inner wall of the outer box. The axial force loading tools are used for axial force loading of the horizontal supports or the vertical supports. The control center is used for controlling the working states of the axial force loading tools. By adoption of the dynamic regulation and control system for the bidirectional steel supporting structure, the problems that in the prior art, the additional bending moment of the bidirectional steel supporting structure is too large during axial force loading, and the bidirectional steel supporting structure cannot be regulated and controlled in real time are solved.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a dynamic control system and a dynamic control method of a two-way steel support structure. Background technique [0002] At present, in the construction of large-scale foundation pits, reinforced concrete is generally used as the horizontal support in the pit for large-scale underground excavation, or the large-scale foundation pit is divided into several long and narrow foundation pits by setting up partition walls, and steel supports are temporarily supported. The construction cost of this method is relatively high, and the construction period is also very long, and the demolition of the concrete structure after the construction is completed has a large workload, high noise and serious pollution, which is not conducive to environmental protection. [0003] At present, another method is to use two-way steel support as the horizontal support after underground excavation, which...
