Slide rail support base and long-span structure system including slide rail support base

Abstract

The invention discloses a slide rail support base and a long-span structure system including the slide rail support base. The slide rail support base comprises an upper sliding rail, a lower sliding rail and a middle rotating support base; the middle rotating support base comprises an upper part of support base and a lower part of support base in rotatable connection with each other; the upper part of support base is in sliding connection with the upper sliding rail; the lower part of support base is in sliding connection with the lower sliding rail; length of the upper sliding rail is more than width; length of the lower sliding rail is more than width. Through such an arrangement, the limitation to displacement direction, displacement volume and stress of the traditional support base canbe overcome, height and width of support base can be adjusted according to requirements, stress is reasonable, processing is convenient and the slide rail support base can adapt to complex stressingconditions and can meet the requirements of architectural modeling.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a sliding rail bearing capable of sliding in multiple directions and large displacement and a large-span building system containing the same. Background technique [0002] Civil engineering plays an important role in national economic construction and is an important part of national economic construction. In recent years, various types of long-span spatial structures have emerged, and one of the difficulties is the design of support nodes. As the most concentrated part of the force, the connection node is very important to the safety of the overall structure. A reasonable support node must have clear force, direct force transmission, safety and reliability, and at the same time, it should be simple and reasonable in structure, easy to manufacture and assemble, and should have good economy. [0003] The continuous emergence of long-span and complex building syste...

Problems solved by technology

As the part with the most concentrated stress, the connection nodes are very important to the safety of the overall structure. Once the connection nodes are damaged, the connected components will lose part or all of their bearing capacity, which may change the force transmission path and cause local damage. will lead to continuous failure of the entire structural system

[0004] At present, there are many multifunctional supports for civil engineering in the market, but there are basically the following problems: 1. The displacement is small and the direction is single, which cannot be applied to buildings with large deformation; 2. The support can only be subjected to tension or compression. It is difficult to achieve both tension and pressure; 3. It is difficult to adjust the height of the support flexibly

[0005] It can be seen that the above-mentioned existing connection node support obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
