Problems solved by technology

Due to the different shapes of the original bamboo poles, especially the differences in the diameter and taper of each original bamboo pole, the traditional original bamboo beam-column joints need to rely on experienced craftsmen to process the original bamboo poles during construction. It meets the standardized assembly requirements, while the reliability of the binding and nailing connection methods is weak, and it is prone to damage under the action of earthquake loads, which cannot meet the design and use requirements of modern structures

Abstract

The invention belongs to the technical field of building materials, and particularly provides a raw bamboo column assembly. The raw bamboo column assembly comprises a joint column, a connecting sleeve and a raw bamboo column, wherein the joint column extends in the first direction, first fixing pieces which are uniformly distributed in the circumferential direction of the joint column are arranged on the side wall of the joint column, and first gaps extending in the first direction are formed in the ends, away from the joint column, of the first fixing pieces; one end of the connecting sleeve is connected with the two ends of the joint column, and an opening is formed in the end, away from the joint column, of the connecting sleeve; and the raw bamboo column comprises at least one raw bamboo rod, the raw bamboo rods extend in the first direction, and one of the ends of the raw bamboo rods enters the opening and is fixedly connected with the connecting sleeve. According to the design of the technical scheme, the connecting sleeve is connected to the raw bamboo column in a matched mode, so that the raw bamboo column is conveniently connected with the joint column, the strength of the joint can be ensured, meanwhile, the mechanical property advantages of raw bamboo are fully exerted, and the raw bamboo column assembly can be applied to assembly construction of raw bamboo beam column joints.

Description

technical field [0001] The application belongs to the technical field of building materials, and specifically discloses an original bamboo column assembly, an original bamboo truss beam-original bamboo column connection node and a construction method. Background technique [0002] China is very rich in bamboo resources, and the bamboo forest coverage area and the number of bamboo species both rank first in the world. However, bamboo forests are mainly distributed in remote mountainous areas such as southern hills and mountains. Using raw bamboo as a building material for village and town housing construction can not only speed up the development and utilization of bamboo resources, but also improve the living environment of villages and towns. [0003] The use of raw bamboo as a building material has a long history in my country, such as using raw bamboo poles as beams or columns, and then connecting them to form a frame structure. In the traditional original bamboo frame ...
