Problems solved by technology

The mortise and tenon joint structure has poor rigidity and is easy to deform; the bolt connection is easy to split the original bamboo and weaken the overall strength; the number of original bamboo rods required for the bundled connection is large, and the bundled material is not durable, which affects the life of the structure
Although the above beam-column connection methods of original bamboo structures are widely used in rural bamboo buildings and residential buildings, their technical deficiencies limit the promotion of public buildings and characteristic residential buildings with bamboo as the main building material.

Abstract

The invention discloses a raw bamboo frame steel pipe structure adapting to raw bamboo diameter changes. The raw bamboo frame steel pipe structure comprises a vertical steel sleeve, the vertical steelsleeve comprises two semicircular vertical steel sleeve assemblies, a plurality of opposite wing plates I are arranged on each of the two semicircular vertical steel sleeve assemblies, rubber gasketsI are arranged between the opposite wing plates I, threaded holes I are formed in the wing plates I, and bolts I penetrate through the threaded holes I to connect the two semicircular vertical steelsleeve assemblies; a plurality of holes I are further formed in the vertical steel sleeve, and a notch I and a plurality of holes II are formed in the joint of the two semicircular vertical steel sleeve assemblies. The method can adapt to standard joint connection of raw bamboos with different diameters, standard joint connection of non-standard raw bamboo rod pieces is achieved, the constructiondifficulty is reduced, the construction process is simplified, the reliability of a raw bamboo frame structure is improved, and industrial technology popularization is facilitated.

Description

technical field [0001] The invention relates to a construction method for steel pipe joints of a raw bamboo frame adapting to changes in the diameter of the raw bamboo, and belongs to the technical field of construction engineering. Background technique [0002] As a traditional local material, bamboo has the characteristics of protecting the ecological environment, short growth cycle, abundant resources, and low cost. Bamboo structures are widely distributed in hot and humid rural areas in southern China. At present, the beam-column joints of the original bamboo structure are mostly connected by mortise and tenon joints, bolt joints and binding. The mortise and tenon connection structure has poor rigidity and is easy to deform; the bolt connection is easy to split the original bamboo and weaken the overall strength; the number of original bamboo rods required for the bundled connection is large, and the bundled material is not durable, which affects the structural life. A...
