Abstract

The invention discloses a pre-restrained bamboo pipe combined component, a joint structure and a construction method. The pre-restrained bamboo pipe combined component comprises a bamboo pipe, and further comprises vertical ribs, filler and annular restraining pieces; holes are correspondingly formed in pipe joints in the bamboo pipe; a group of vertical ribs are provided and are inserted into thebamboo pipe at intervals; an inner cavity of the bamboo pipe is filled with the filler; multiple groups of annular restraining pieces are arranged on the outer side of the bamboo pipe in the verticaldirection at intervals. The technical problems that in a traditional bamboo structure, bamboos are prone to cracking during drying, the structural safety is poor, the whole structure is deformed because the bamboos are loosened at the connecting positions after being air-dried and contracted, the fireproof performance of the bamboo structure is poor, and the reliability of connecting joints is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a pre-constrained bamboo tube composite component, a node structure and a construction method thereof. Background technique [0002] Bamboo structure is a kind of prefabricated structure, which has the advantages of fast growth, green and environmental protection, and has a long history of application in our country. China has done a lot of research on the application of bamboo in construction. In addition to measuring the physical and mechanical properties of bamboo, tests on the bearing capacity of whole bamboo rods, bolt connections and bamboo roof trusses were also carried out, and various forms of bamboo structures were proposed. However, when the bamboo is dry, it is easy to crack, which reduces the safety of the structure, and when the bamboo shrinks in the air, it relaxes at the connection and deforms the entire structure; in addition, the fire resistance o...
