Bamboo-based composite cavity structural slab and construction process

Abstract

The invention discloses a bamboo-based composite cavity structural slab and a construction process. The bamboo-based composite cavity structural slab is characterized in that an upper panel, a lower panel and a rib plate form a space bamboo rib framework, an externally-wrapped cementing material is poured, the upper panel and the lower panel are formed by assembling longitudinal bamboo ribs, the butt joints of the longitudinal bamboo ribs are spaced by a certain distance, and epoxy resin sleeve type joint connection is formed at the butt joint by pouring epoxy resin; and the rib plates are formed by assembling vertical short bamboo ribs, rib plate inner bamboo ribs extend out of the rib plates, and the rib plate inner bamboo ribs are connected with the upper panel and the lower panel in a gelling mode. The upper panel and the lower panel of the cavity structural slab are connected through the epoxy resin sleeve type joints, the connecting strength of the panels is high, the rib plates are in gelling connection with the upper panel and the lower panel through the rib plate inner bamboo ribs, the overall connecting strength of the cavity structural slab is high, and the cavity structural slab has the advantages of being light in weight, high in strength, good in ductility, good in heat preservation and sound insulation performance and good in waterproof and moistureproof performance, good in anti-cracking performance, good in fireproof and anti-corrosion performance, convenient to construct and install and the like.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to green building and environmental protection composite boards, in particular to a bamboo-based composite cavity structural board and a construction process. Background technique [0002] The existing bamboo-based composite board design schemes are: [0003] Recombined Bamboo Solution: It is a new bamboo material that reorganizes and strengthens the bamboo material, that is, the bamboo material is processed into long bamboo strips, bamboo filaments or crushed into bamboo filament bundles, which are then dried and dipped in glue. It is then dried to the required moisture content, then laid in the mold and cured by high temperature and high pressure. [0004] Bamboo winding scheme: Bamboo winding urban comprehensive pipe corridor is a "Made in China" product with core intellectual property rights. It is different from steel pipes, concrete and other pipe corridors commonly u...

Problems solved by technology

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 non-load-bearing walls, the amount of construction is large, and the cost of traditional wall panels is low, which is not suitable for the promotion of bamboo winding technology

[0008] The above-mentioned prior art only pays attention to the embryonic structure and pattern of bamboo tendons, and does not fully consider the connection strength of the joints between the bamboo tendons, nor does it consider the connection performance of the joints of the composite panel, resulting in the occurrence of bamboo tendon disjoint, Possibility of sheet damage and composite panel collapse
