Embodiment Construction

[0018] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0019] A support for adaptive foundation uneven settlement, such as figure 1 As shown, the support 2 is arranged between the frame column foot 1 and the rigid foundation 3 . Including coaxial active pull rod 6, inner cylinder 5, outer cylinder 4 and spring 10, such as figure 2 shown. Wherein, movable pull bar 6 is made of the top plate 11 and chassis 8 that are arranged horizontally up and down and the longitudinal bar 12 that connects top plate 11 and chassis 8 centers, as image 3 shown. The inner cylinder 5 is sleeved on the longitudinal rod 12 and can move up and down freely, and the outer wall of the inner cylinder 5 is covered with threads, such as Figure 4 shown. A spring 10 in a relaxed state is provided between the lower surface of the top plate 11 of the movable pull rod 6 and the top ...

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...
