Embodiment 1
[0044] (1) Wallboard production
[0045] Ⅰ. Use recombined bamboo to make wallboard panels, with a size of 600mm×600mm and a thickness of 20mm. The edges are made into ribs and grooves, and one side of the panel is covered with fireproof cotton;
[0046] Ⅱ. Connect the inner and outer plates with the pull bolts and the grille, the size of the grille is 10mm×10mm, and the spacing is 150mm;
[0047] Ⅲ.Using waste concrete to make foam concrete, as the core material of wall panels, pouring and curing.
[0048] Ⅳ. Utilize the ribs and grooves at the sides, assemble the wall panels, and fill the joints with foaming agent.
[0049] (2) Mechanical performance test
[0050] The mechanical strength of the recombined bamboo indoor board and outdoor board measured by the material test is shown in Table 1:

The invention discloses a combination siding wall method of reconstituted bamboo-foam concrete. According to the method, a reconstituted bamboo plate is cut into square plates to be used as an inner plate and an outer plate, convex ribs are formed on the left side and the upper side of the inner plate and the outer plate, grooves are formed on the corresponding lower side and the right side, holesare drilled at four corners of the inner plate and the outer plate and the center of the plate, then fireproof cotton is respectively paved on one sides of the inner plate and the outer plate, a plurality of groups of reconstituted bamboo grids are made, the inner plate and the outer plate are connected, the reconstituted bamboo grids are connected by cross braces to serve as horizontal supports,and the inner plate and the outer plate are fixed in the holes through opposite pull bolts. According to the method, the reconstituted bamboo is used as a panel, and the stress performance and the seismic resistance are good; foam concrete is prepared from building waste renewable resources and is used as a wallboard core material, and the effects of recycling resources, saving energy and reducing emission are realized; and an organic material and an inorganic material are combined, and the functional limitation of siding wall made of a single material is improved.
Description
technical field [0001] The invention belongs to the field of construction engineering, and specifically relates to a method of recombining bamboo-foam concrete composite slab walls. Background technique [0002] Building energy conservation and emission reduction has become an important way for the world to solve the global energy crisis and environmental pollution. With the acceleration of urbanization in my country, building energy consumption will inevitably become an important growth point of energy consumption. Therefore, vigorously developing building energy conservation is the top priority of my country's energy conservation work middle. [0003] Bamboo is a natural renewable material with a short growth cycle and abundant resources. Reconstituted bamboo is a bamboo-based composite material made of bamboo bundles that are pressed and glued together. Recombined bamboo has good mechanical properties and is widely used in furniture, indoor and outdoor floors, and structu...
