A connection node and installation method of hollow spheres of bamboo reticulated shell with welded steel inserts

Abstract

The invention provides a bamboo latticed shell hollow sphere connecting joint welded with steel insertion sheets and an installing method. The bamboo latticed shell hollow sphere connecting joint comprises M steel insertion sheets, M bamboo rod pieces, M or M-1 reinforced steel sheets, a hollow sphere and 2M bolts, wherein a circular-arc gap is reserved in one end of each steel insertion sheet; a bolt hole A is reserved in the other end of each steel insertion sheet; one end of the circular-arc gap reserved in each steel insertion sheet is fixed together with the hollow sphere by welding; a groove and a bolt hole B are reserved in the end part of the each rod bamboo rod piece; one end, where the bolt hole is reserved, of each steel insertion sheet is inserted into the groove reserved in each bamboo rod piece; the bolt hole A reserved in each steel insertion sheet is aligned with the bolt hole B reserved in each bamboo rod piece; each bolt hole A and bolt hole B are fixed by using two bolts; the reinforced steel sheets are welded on the steel insertion sheets between the bamboo rod pieces and the hollow sphere. The bamboo latticed shell hollow sphere connecting joint has the advantages of simple structure, easiness in positioning and installing, clear force transmission, high integrity, easiness in maintaining and environmental friendliness; bamboo belonging to an environment-friendly renewable resource is taken as the rod piece material of the latticed shell connecting joint, so that an outstanding environmental protection advantage is achieved.

Description

technical field [0001] The invention relates to a hollow ball connection node of a bamboo reticulated shell welded with steel inserts and an installation method thereof, belonging to the field of reticulated shell structures. Background technique [0002] The reticulated shell structure is a spatial structural system based on rods arranged regularly along a certain curved surface, with the "membrane" effect as the main force characteristic. The reticulated shell structure has light weight, good structural rigidity, variable structure, strong aesthetics, and can span a large space, so it has broad development space. Reticulated shell structures widely use steel and aluminum alloys as the main structural materials. There are no examples of bamboo being used in reticulated shell structures, and there are no examples of bamboo reticulated shells connecting nodes. [0003] In my country, bamboo is a renewable and degradable biomass material with abundant resources and short grow...

Problems solved by technology

[0004] However, bamboo is different from steel and aluminum, which can be directly welded and connected, and unlike concrete, which can be fused and solidified by itself. If we learn from the mortise and tenon connection of traditional wood structures, the section of the bamboo connection end will be weakened, the joint strength will be reduced, and brittle failure will easily occur.
