Production method of building peripheral guard board with multi-layer bamboo lattice board as inner framework

Abstract

The invention relates to a production method of a building peripheral guard board with multiple layers of bamboo blank plates as an inner framework, which comprises the following steps of: manufacturing the bamboo blank plates by using bamboo chips, overlapping the multiple layers of bamboo blank plates in a staggered manner and bonding by using glue, fixing steel wire meshes on two surfaces of the multiple layers of bamboo blank plates, and filling foaming materials or cement mortar by using the multiple layers of bamboo blank plates as the inner framework. Bamboo fiber composite polymer cement or gypsum slurry is used as a surface layer to manufacture a building peripheral guard board; according to the production method of the building peripheral guard board with the multi-layer bamboo lattice board as the inner framework, the bamboo is internally and externally sealed through modern building materials, the bamboo is isolated from air, and therefore it is guaranteed that the service life of the bamboo is synchronous with that of a building, energy is saved, carbon emission is reduced, and the production method is suitable for manufacturing the large building peripheral guard board.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a production method of a building outer protection board with a multi-layer bamboo space board as an inner skeleton. Background technique [0002] At present, most of the prefabricated building exterior panels use steel bars as the skeleton, which increases the amount of steel and aggravates carbon emissions. It is rare to use naturally grown bamboo as the inner skeleton of the building exterior panels. This is mainly due to the traditional bamboo material. In a sense, it is easily damaged by insect pests and natural forces. Bamboo has a short service life, especially the erosion of air, ultraviolet rays and mold. The use of bamboo to replace steel bars in concrete has been criticized as a "tofu slag project". It is isolated from the air in the state and can be immortalized for thousands of years to avoid oxidation; Bamboo can be used to replace steel bars for industrialized man...

Problems solved by technology

[0002] At present, most of the prefabricated building enclosures use steel bars as the skeleton, which increases the amount of steel and intensifies carbon emissions. It is rare to use naturally grown bamboo as the inner skeleton of the building enclosure. This is mainly due to the traditional bamboo materials. In the sense, it is vulnerable to damage by insects and natural forces. The service life of bamboo is short, especially the erosion of air, ultraviolet rays, and mold. The use of bamboo to replace steel bars in concrete has been criticized as a "tofu dregs project". It can be isolated from the air in the state and avoid oxidation, which can be immortal for thousands of years; bamboo can be used to replace steel bars for industrialized manufacturing of building structures, and bamboo can be immortal for a hundred years when it is closed in concrete; my application number is 202111336269.3 A kind of composite orthogonal bamboo perforated plate In the preparation method of the thermal insulation cement pentahedron module, the method of drilling holes with bamboo chips and perforating bamboo tendons to form bamboo perforated panels has the disadvantage that it is difficult to make large-scale building panels. A multi-layer bamboo blank panel of the present invention is The production method of the building outer guard plate of the inner skeleton, its technical route is, soak with polymer anti-insect, anti-corrosion, water-proofing agent with bamboo chip, dry with hot flue gas, make a plurality of recesses with machinery on one side of bamboo chip. Teeth, use a plurality of bamboo slices with concave teeth, the concave teeth are glued and intersected to make a bamboo space board with small and large holes in the "Tian" grid, use multi-layer bamboo space boards, and glue the spaces staggered Bonding, using wire mesh to fix on both sides of the multi-layer bamboo grid, using stainless steel hoops or plastic binding to fix the multi-layer bamboo grid, inserting and welding metal connectors on the four sides of the multi-layer bamboo grid, using multi-layer bamboo grid The board is filled with foaming material or cement mortar for the inner skeleton, and the building outer shield is made of bamboo fiber composite polymer cement or gypsum slurry as the surface layer; this kind of multi-layer bamboo hollow board is the inner skeleton of the building outer shield The production method of the bamboo is insect-resistant, anti-corrosion, waterproof, and dry-treated with polymers, and the bamboo is sealed internally and externally with modern building materials to isolate the bamboo from the air, thereby ensuring that the service life of the bamboo is synchronized with the building; using natural growth Bamboo replaces steel bars, saving energy and reducing carbon emissions; the filling material is in the form of a "back" structure between the skeletons of multi-layer bamboo hollow panels, which makes the overall strength of the building enclosure high, and is suitable for making large-scale building enclosures
