Problems solved by technology

However, these supports mainly have the following problems: only one-way or fixed two-way release of temperature stress is allowed, and the deformation freedom given to the steel structure is not large enough, so that the support directly bears the bending moment

Abstract

The invention provides a bidirectional displacement-limiting sliding support structure and an assembling method thereof, relates to the technical field of grid structures. The bidirectional displacement-limiting sliding support structure is used in a grid structure comprising a grid rod member and a steel column, and comprises a sliding support fixed at the top end of the steel column, a support stand column slidably connected with the sliding support, at least one limiting circular pipe arranged on the support stand column in the X-axis direction, at least one limiting pipe arranged on the support stand column in the Y-axis direction, and a telescopic device installed in the limiting circular pipe. The grid rod member extends into the limiting circular pipe to abut against the internal telescopic device; the sliding support is provided with a sliding groove, and the support stand column can move in the X-axis direction and the Y-axis direction of the sliding groove; and the support stand column can move in the Z-axis direction but is limited. Stress generated by the steel structure due to the temperature effect can be released through a support sliding method, and the bending moment of a connecting node can be released through the support micro-rotation, so that the displacement-limiting hinging effect of the support is realized.

Description

technical field [0001] The invention relates to a bidirectional displacement-limited sliding support structure and an assembly method, belonging to the technical field of grid structures. Background technique [0002] In the field of steel structures, the temperature stress caused by temperature effects has a great influence on the strength and stability of steel components. It can be seen from the formula ΔL=L×α×ΔT that there is a linear relationship between the deformation displacement of steel members and its length L, linear expansion coefficient α, and temperature difference ΔT. If there are too many, it will cause the grids to squeeze each other and produce extrusion stress, which will have an adverse effect on the stability and strength of the grid. In order to eliminate the adverse effects of temperature stress on the structure, many steel structure buildings in my country have begun to use spherical hinge bearings, sliding bearings, spherical steel bearings, rubber...
