Adaptive support for uneven foundation settlement and working method thereof

Abstract

The invention provides an adaptive support for uneven foundation settlement and a working method thereof. The support is arranged between a frame column foot and a rigid foundation and comprises a moving pulling rod, an inner cylinder, an outer cylinder and a spring, wherein the moving pulling rod, the inner cylinder, the outer cylinder and the spring are coaxially arranged. The moving pulling rodis composed of a top tray, a bottom tray and a longitudinal rod for connecting the centers of top tray and the bottom tray, the inner cylinder is installed on the longitudinal rod in a sleeving modeand can move up and down freely, the spring in a releasing state is arranged between the top tray and the inner cylinder, and an occlusion mechanism use for preventing relative rotation is arranged between the bottom face of the inner cylinder and the bottom tray. The inner cylinder is sleeved with the outer cylinder and a matching thread is arranged at the part where the outer cylinder is in contact with the inner cylinder. The support has the ability of adaptive uneven foundation deformation, the non-uniform settlement of a frame structure with a foundation can be eliminated automatically byusing the automatic extension of a support structure, and the sensitivity is relatively high; and in addition, the support is simple in structure, can be replaced and maintained at any time, has relatively high resistance to pressure, bending and shear, can provide a foundation for better application of the frame structure, and has a wide range of practicability.

Description

technical field [0001] The invention relates to a frame structure, in particular to a support for the frame structure and its working method. Background technique [0002] Frame structure buildings are widely used in our country, but the performance of pure frame structure against uneven deformation of foundation is poor, and uneven settlement will cause large additional internal force and additional deformation of beams and columns of frame structure. Therefore, Section 5.3 of my country's "Code for Design of Building Foundations" (GB50007-2011) gives relevant restrictions on the allowable value of building foundation deformation, and Article 5.3.3 stipulates that for frame structures and single-story bent structures The control of the settlement difference of the column foundation limits the application of frame structure buildings to foundations with uneven settlement. [0003] The current measures to reduce uneven settlement are, on the one hand, to avoid uneven settleme...

However, these two measures are based on "hard resistance" as the leading idea to reduce uneven settlement. Although they can achieve certain effects, their structures are complex, difficult to assemble and disassemble, and greatly increase the cost of buildings.
