A prefabricated bamboo-aerated concrete composite structure and its manufacturing method

Abstract

An assembled type bamboo-aerated concrete combined structure comprises a prefabricated aerated concrete board (1), a bamboo beam (2), a perforated metal plate (3), adhesives (4) and pore-filling materials (5), wherein the prefabricated aerated concrete board (1) is located on the bamboo beam (2), the axes of the prefabricated aerated concrete board (1) and the bamboo beam (2) are parallel, the prefabricated aerated concrete board (1) and the bamboo beam (2) are identical in length, the bottom surface of the prefabricated aerated concrete board (1) is tightly connected with the top surface of the bamboo beam (2), and the prefabricated aerated concrete board (1) and the bamboo beam (2) are integrated through the perforated metal plate (3), the adhesives (4) and the pore-filling materials (5). According to the invention, the defects that bamboo structures are low in flexural rigidity, insufficient in spanning capacity, and the like are overcome. The assembled type bamboo-aerated concrete combined structure has the comprehensive advantages that the assembled type bamboo-aerated concrete combined structure is light and good in sound insulation performance, thermal insulation performance and earthquake resistance. In terms of implementation methods, industrial production is achieved favorably by the mounting process of the assembled type bamboo-aerated concrete combined structure, and the assembled type bamboo-aerated concrete combined structure is applicable to the field of civil construction structures.

Description

technical field [0001] The invention relates to a composite structure, in particular to an assembled bamboo-aerated concrete composite structure and a manufacturing method, belonging to the field of civil and architectural structures. Background technique [0002] The development of civil engineering structures requires new materials and new structures. As a new generation of green and environmentally friendly materials, bamboo has the advantages of fast growth and easy access to raw materials, low consumption during processing, and light weight and high strength. However, it also has defects such as low elastic modulus, small structural section stiffness, and large deflection deformation. Most of them use stiffness control design, resulting in low strength utilization of materials. For example, the ultimate bearing capacity of the flexural members of the bamboo structure is about 1 / 5 of the ultimate bearing capacity calculated according to the strength check according to t...
