Description

Connection structure for large-span steel bamboo building Technical Field The invention belongs to the technical field of large-span buildings, and particularly relates to a connecting structure for a large-span steel-bamboo building. Background Most of the building materials used in the building construction in China are traditional building materials at present, and the building materials are building materials which are not sustainable in development from the aspects of resource and energy consumption, land damage or environmental pollution. Bamboo has the characteristics of easy propagation, fast growth, early wood formation, high yield and the like, so that more and more steel bamboo buildings appear, but how to fully utilize the steel bamboo material to build the large-span building with beautiful morphology and good mechanical property is still a very key problem. At present, most of bamboo is bent by adopting a fire baking mode and is bound by using a coir rope to form various curves or curved-surface buildings, and after the bamboo is used for a long time, the 'loose binding effect' of the coir rope can occur, so that the structural safety cannot be ensured, the durability of the coir rope becomes worse and worse along with the change of the temperature and humidity of the building, and the problem of difficult replacement or reinforcement at the later stage of use also exists. Considering the characteristics of good building aesthetic feeling and excellent mechanical property of natural steel bamboo, how to fully utilize the vertical initial form of the natural steel bamboo and combine with reasonable connecting nodes to form a large-span steel bamboo building with low cost, safe structure and attractive building is a technical problem to be solved by the technicians in the field.
