Description
Technical Field
The invention relates to a bidirectional limiting and moving sliding support structure and an assembling method, and belongs to the technical field of grid structures.
Background
In the field of steel structures, temperature stress caused by temperature effect has great influence on the strength and stability of steel members. As can be seen from the formula Δ L ═ lx α × Δ T, the deformation displacement of the steel member has a linear relationship with its length L, linear expansion coefficient α, and temperature difference Δ T, so that in the case of a large temperature difference, the displacement Δ L of the large-span grid structure is too large, which causes the mutual extrusion of the grids to generate extrusion stress, thereby adversely affecting the stability and strength of the grids. In order to eliminate the adverse effect of temperature stress on the structure, many steel structure buildings in China begin to adopt spherical hinge supports, sliding supports, spherical steel supports, rubber supports, elastic tension supports and the like. However, these supports have the following problems: temperature stress is released only in one direction or in two directions, the deformation degree of freedom of the steel structure is not large enough, and the support can directly bear the action of bending moment.
The present application was made based on this.
