First sliding and then hinged support and connection method

Abstract

The invention discloses a first sliding and then hinged support and a connection method. Firstly, a lower structure is implemented and completed, an embedded part is reserved in the lower structure, the bottom of a sliding support is fixed on the lower structure through the embedded part, an upper structure is connected to the top of the sliding support, and after the upper structure is implemented and completed and horizontal force is released, and deformation becomes stable, a limiting device is added to limit movement of the sliding support, so that the limited sliding support only rotatesin an axial direction, thereby changing the sliding support to a hinged support. According to the support and the method, the requirement of mutual sliding of a connecting part under the complex stress condition in an implementation process is firstly met, and horizontal force and deformation of mutual action of the connecting part are released. During subsequent use, the stability of the structure can be enhanced by converting the sliding support into the hinged support, mutual sliding can be limited, so that the final structure can eliminate the rigid connection damage effect in the implementation process, can further enhance stability in a use process, and the method has the characteristics of simple implementation, clear principles, strong practicability and the like.

Description

technical field [0001] The invention relates to a first-slide-then-hinge support and a connection method. Background technique [0002] At present, there are mainly three types of sliding bearings: fixed bearings, hinged bearings and sliding bearings. The general bearing design mainly adopts a single connection method, and the process will not change after setting. In many building structures, the load during the construction process is relatively large, and the connection between the upper structure and the lower structure produces a large horizontal force and horizontal deformation. The horizontal force and horizontal deformation will cause damage to the lower connecting components. During the construction process This part of the force must be released in the process, and the process can be connected through the set sliding support. At present, most designs adopt this single connection method. Since the overall stability of the sliding connection is relatively poor, and ...

AI Technical Summary

Problems solved by technology

Since the overall stability of the sliding connection is relatively poor, and the horizontal force and horizontal deformation are basically in a stable state after the construction is completed, if the sliding support connection is still used for design, only by adding structural measures and increasing the section of the bar, etc. Measures to address stability issues

However, the supported structure forms a fixed support of a rigid structure, which cannot release the bending moment. Therefore, a support connection method that can slide first and then hinge is designed.
