Problems solved by technology

The disadvantages are that the ability to resist bending moment is slightly weak, the overall rigidity of the structure is poor, the natural hollow structure causes the hollow part to be not fully utilized, the growth limitation leads to a diameter of 10-15cm, the individual strength varies greatly, and the strength of the head and tail of the same bamboo tube is different. Defects, making it difficult to use bamboo as a bending member and compression member to support the reliability requirements of most buildings

Abstract

The invention discloses a composite reinforced bamboo pipe component with inner fillers and a preparation method thereof. The bamboo pipe component comprises a hollow bamboo pipe for breaking through bamboo joints and a plurality of bamboo strips located in the bamboo pipe. A circle or multiple circles of bamboo strips are arranged. The surfaces of the bamboo strips are coated with epoxy resin adhesives which are arranged and fixed around the inner wall of the bamboo pipe. According to the composite reinforced bamboo pipe component with the inner fillers and the preparation method thereof, the inner space of bamboo is made full use of on the premise that the shape of the bamboo is not changed, and the aesthetic feeling and the efficient use of the space are combined, so that the flexural property and the compressive property of the bamboo are greatly improved.

Description

technical field [0001] The invention relates to the technical field of structural components of buildings, in particular to a bamboo tube component reinforced with a composite inner filler and a preparation method thereof. Background technique [0002] Building components refer to the various elements that make up a building. Structural components are the elements that constitute the structural skeleton of a building. They can be used as beams, slabs, walls, columns, foundations, etc. of buildings. They are generally divided into flexural components and compression components according to their stress characteristics. [0003] Raw bamboo is a renewable resource. In southern China, where bamboo is abundant, houses have been built with bamboo for a long time. Moso bamboo for structure can be grown all over southern China. Generally, it takes 4 to 6 years to become a useful product. The diameter of moso bamboo is 10 to 15 cm, hollow and tubular, with a diaphragm inside, and ...
