Description

Technical Field

[0001] The utility model relates to the technical field of building structure engineering, in particular to a reorganized bamboo grid structure. Background Art

[0002] Bamboo has broad prospects for engineering application due to its many advantages such as rich resources, energy saving, environmental protection, and good economic benefits. It can be used as a supplementary material for steel and concrete. However, due to the rich starch, sugars, etc. in the cells, raw bamboo is prone to corrosion, mildew and insect in warm and humid environments, and its durability is insufficient. Reconstructed bamboo is a new type of bamboo composite material, which is made from raw bamboo through processes such as impregnation, drying, embryo formation and gluing.

[0003] The existing application of reconstituted bamboo as a new material in structural construction is still in its infancy. Currently, there are few mature structural systems that can be used in actual projects, making it difficult to promote and apply. As a result, reconstituted bamboo structures are mainly used in non-structural components such as flooring, furniture, and container floors. For example, a Chinese patent discloses a "reconstituted bamboo frame structure node connection" with the application number "CN201220069879.1". It consists of: reconstituted bamboo columns, prefabricated reconstituted bamboo beams, steel hoops, supports, and bolts. Its device structure is simple, and there are problems such as complex assembly steps, long construction time, insufficient structural force integrity, and potential damage and failure at the node connections, which limits its applicability.

[0005] The utility model also provides the above-mentioned reorganized bamboo truss structure, comprising: an upper chord, the lower surface of the upper chord is fixedly connected to a web, the lower surface of the web is fixedly connected to a lower chord, and the upper surface of the lower chord is fixedly connected to a channel steel connector; through the mutual cooperation between the above-mentioned parts, compared with simply using connectors for connection, the strength and rigidity of the truss nodes are greatly improved.

[0006] The lower chord is provided with threaded holes on its side, and the channel-shaped steel connector is provided with bolts on its side. The channel-shaped steel connector is fixedly connected to the lower chord via bolts. The interaction between these parts improves the overall load-bearing performance of the grid, significantly enhancing the flexibility, reliability, and operability of the overall structure.
