Engineering bamboo beam and column connecting joint structure

Abstract

The invention provides an engineering bamboo beam and column connecting joint structure. The engineering bamboo beam and column connecting joint structure comprises one engineering bamboo beam, one engineering bamboo column and at least one beam column connecting assembly, and the engineering bamboo beam is perpendicularly connected with and fixed to the engineering bamboo column through the beamcolumn connecting assembly; the beam column connecting assembly comprises a at least two beam column connecting parts and a plurality of bolt assemblies, the beam column connecting parts comprise oneengineering bamboo column installing grooves and one engineering bamboo beam installing groovesperpendicular to each other, the two beam column connecting parts are oppositely arranged on the two sides of upward and downward of the engineering bamboo beam, and the two beam column connecting parts cover a same side of the engineering bamboo column through the engineering bamboo column installing grooves and are connected with and fixed to the engineering bamboo column through the bolt assemblies; and one end part of the engineering bamboo beam is arranged in the engineering bamboo beam installing grooves of the two beam column connecting parts in an inserting mode and is attached with groove arms of the engineering bamboo beam installing grooves, and the engineering bamboo beam is connectedwith and fixed to the beam column connecting parts through the bolt assemblies. The engineering bamboo beam and the column connecting joint structure can improve a bearing capacity, an initial rigidity, a rotating capacity and a ductility property of a joint, and can be efficiently and rapidly installed.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an engineering bamboo beam-column connection node structure. Background technique [0002] my country is the world's largest bamboo producer, rich in bamboo resources. Bamboo is a low-carbon and renewable biomass material with the advantages of high strength-to-weight ratio, light weight and earthquake resistance. It is a high-quality and potential structural material that can be used for load-bearing structures such as frame beams and columns. Engineering bamboo, such as glued bamboo, recombined bamboo, etc., is a board made of round bamboo through cutting, cooking, carbonization, drying, gluing, reorganization, etc. The mechanical properties are significantly improved, and the durability is significantly improved, which can meet the application requirements of bamboo in building structures. [0003] In the engineering bamboo frame structure, the connection between the beam an...

Problems solved by technology

[0003] In the engineering bamboo frame structure, the connection between the beam and the column can be realized through the steel plate and the bolt connector, but due to the unidirectionality of the engineering bamboo fiber, when the joint rotates, the extrusion of the bolt to the bamboo on the hole wall will easily cause the cross-section of the bolt. Splitting damage occurs, causing the overall failure of the structure, and the strength and deformation capacity of the beam-column components are not fully utilized

At present, there is still a lack of an engineering bamboo beam-column joint structure that can ensure that the joint has the strength, stiffness and deformation capacity that match the component, prevent the splitting of the engineering bamboo in the joint area, and adapt to the machinability of the engineering bamboo.
