Steel-bamboo combined engineering bamboo beam-column connecting structure and preparation method thereof

Abstract

The invention relates to the technical field of steel-bamboo combined application, in particular to a steel-bamboo combined engineering bamboo beam-column connecting structure. The connecting structure comprises two engineering bamboo columns, an engineering bamboo beam erected between the engineering bamboo columns, a first steel plate and a second steel plate, wherein a vertical groove is formed in the bottom of the engineering bamboo beam, inserting grooves are formed in the engineering bamboo columns, the two ends of the second steel plate are embedded in the inserting grooves, the middle of the second steel plate is embedded in the vertical groove, the second steel plate is perpendicularly welded to the first steel plate, the first steel plate is bonded with the bottom of the engineering bamboo beam, and the ends of the second steel plate is fixedly connected with the engineering bamboo beam and the engineering bamboo columns through bolts. The invention further provides a preparation method of the steel-bamboo combined engineering bamboo beam-column connecting structure. The preparation method comprises five steps. According to the connecting structure, the flexural strength and flexural rigidity of an engineering bamboo flexural component can be effectively improved, and the utilization rate of materials is increased; and meanwhile, component reinforcement and assembly type connection integration can be achieved, construction is efficient and rapid, and good application prospects are achieved.

Description

technical field [0001] The invention relates to a steel-bamboo-combined engineering bamboo beam-column connection structure and a preparation method thereof, which can be used to improve the flexural strength and flexural stiffness of engineering bamboo bending components, and realize the integration of component reinforcement and assembly-type connection, belonging to steel Bamboo combined application technology field. Background technique [0002] Bamboo is a low-carbon renewable biomass material, which has the advantages of easy degradation, high strength-to-weight ratio, good thermal insulation performance, light weight and earthquake resistance. my country is the most important bamboo producing country in the world, and its bamboo species, bamboo forest area, bamboo forest stock and output all rank first in the world. Therefore, the promotion of bamboo building materials and bamboo structure buildings has natural advantages and great potential. [0003] In recent years...
