Permanent bamboo-based composite bearing plate and processing technology

Abstract

The invention relates to a permanent bamboo-based composite bearing plate. The permanent bamboo-based composite bearing plate comprises assembly bamboo canes, fiber gridding cloth and a cementing material, wherein the assembly bamboo canes are formed by longitudinally cutting bamboos, the bamboo canes are vertically placed during assembly, and first gaps are formed between the adjacent bamboo canes at intervals; the fiber gridding cloth is attached to the upper surfaces and the lower surfaces of the assembly bamboo canes and completely wraps the side surfaces and the end surfaces of the assembly bamboo canes from the peripheries; the cementing material is poured into the first gaps, as well as the upper surface and the lower surface of the outer side and the peripheral side surface of thefiber gridding cloth, the cementing material in the first gaps forms thin-wall connecting supporting ribs, and the cementing material on the upper surface and the lower surface of the outer side and the peripheral side surface of the fiber gridding cloth forms a bearing protection bonding layer. The permanent bamboo-based composite bearing plate not only can give consideration to bearing strength,but also can realize the advantages of energy conservation, environmental protection, safety, low consumption, high temperature resistance, low temperature resistance, wear resistance, corrosion resistance, seepage resistance and high fire resistance.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a green building environmental protection composite board, in particular to a permanent bamboo-based composite bearing board and a processing technology. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, people have higher and higher requirements for the quality of building products and building materials. Use of green building materials. Green building materials are building materials produced using clean production technology and industrial or urban solid wastes. New functional building materials. The raw materials used in its production use as little natural resources as possible, and a large amount of wastes such as tailings, garbage, and waste liquids are used; low-energy-consumption manufacturing processes and production technologies that do not pollute the environment are used; in the pr...

Problems solved by technology

Moreover, these panels have poor crack resistance. Due to poor stiffness and strength, it is difficult to construct large panels, resulting in many splicing seams on site, and leakage is common during use.

[0004] Bamboo is a kind of green material with abundant resources in our country. However, it is rarely used in construction projects at present. In the field of municipal pipe corridors, which has made breakthroughs, bamboo winding composite technology using thermosetting resin as adhesive is used. In civil construction projects, it is especially difficult to use building wall panels and floor slabs. Bamboo winding technology is suitable for making pipes, but it is more difficult to apply to thinner building wall panels

Moreover, the price is higher, the process is more complicated, and the on-site connection construction is more difficult. Compared with traditional wallboards, it has no comprehensive advantages.

Especially for the load-bearing wall, the construction volume is large, and the current bamboo-based boards are used in the building structure boards, and there is no suitable processing technology and structure.

[0005] Although there are related patent documents on bamboo-based materials in the prior art, the anti-corrosion problem of the materials during use has not been fully considered, nor have the requirements of the board's compression resistance, tensile resistance, bending resistance and coordinated deformation been considered. Lightweight, thin-walled or non-load-bearing structural panels, without considering the strength, bearing capacity and deformation requirements of the panels, cannot be widely used in building structures, especially load-bearing structures
