Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 , figure 2 , image 3 , a concrete implementation method of a stage-by-stage bearing method for steel structural columns in geologically uneven and complex areas is as follows:
[0038] (1) Firstly, set the support frame 5 at the lower part of the horizontal members on both sides of the steel structure column 1 that needs to be loaded in stages. Since the bearing capacity of the foundation bearing capacity of the steel structure column 1 in the position of the geologically uneven slope does not meet the requirements, a separate method is used. The stage bearing method shares the force of the dead load on the steel structure columns 4 on both sides,
[0039] Firstly, two sets of supporting tire frames 5 are respectively arranged at the lower part of the horizontal members 3 on both sides of the stage-loading steel str...

The invention relates to a phase-based bearing method for a steel structure column of geological non-uniform complex areas. A supporting jig frame and a hydraulic jack are arranged to unload the mounted steel structure column, constant loads borne by the upper portion are apportioned onto other steel structure columns on the two sides, and the steel structure column is reconnected to bear live loads applied subsequently after constant load application is completed. Through the internal force redistribution of the steel structure column, the constant loads are unloaded to reduce the acting force of the steel structure column on a foundation, and the problem of insufficient foundation bearing capacity of the steel structure column of the geological non-uniform complex area is solved. The method has the beneficial effects that investment is saved while the problem of insufficient foundation bearing capacity in the complex areas is solved, the construction period is shortened, obvious economic and social benefits are achieved, and the method is suitable for foundation processing of the geological non-uniform complex areas.
Description
technical field [0001] The invention relates to a stage-by-stage bearing method for a steel structure column in a geologically uneven and complicated area. Background technique [0002] In the field of housing construction, there are many ways to deal with the lack of foundation bearing capacity in areas with uneven geology. At present, the main methods are to increase the depth of foundation excavation to the bearing layer, and adopt various forms of reinforcement such as replacement, dynamic compaction, and pile foundation. Way. The above methods are very difficult to deal with the uneven bearing capacity of rocky slopes, and the treatment methods are costly and dangerous, and often cost a lot of money and fail to meet the required requirements. [0003] In the implementation of engineering projects, when the steel structure column falls on the upper part of the foundation with uneven bearing capacity of the slope rock, there are several traditional methods to deal with i...
