Bamboo three-way mesh shell

Abstract

The invention relates to a bamboo three-way grid reticulated shell. The bamboo three-way grid reticulated shell consists of an upper three-way grid type spherical reticulated shell, a lower support rod system and a concrete foundation; a plurality of weft multilateral ring-shaped components are concentrically arranged by taking a center steel node as center; the center steel node is connected with a steel node at the head-tail connection place of a weft rod of the inner weft multilateral ring-shaped component through a radial rod; every two adjacent weft multilateral ring-shaped components are connected through a triangular inclined strut and a radial rod; a vertical support is connected with the upper three-way grid type spherical reticulated shell through a steel node on the outermost weft multilateral ring-shaped component; a Y-shaped upper support is connected with the upper three-way grid type spherical reticulated shell through a steel node on the secondary outer weft multilateral ring-shaped component; a Y-shaped lower support is connected with a transverse connecting rod through a steel node; the vertical support and the Y-shaped lower support are connected with the concrete foundation through basic steel nodes. The bamboo three-way grid reticulated shell has the advantages of being light in dead weight, large in span, high in rigidity, good in structural integrity, simple and convenient to construct, green, environment-friendly and good in economy.

Description

Technical field [0001] The invention relates to a bamboo building, and relates to a main structure spherical net shell structure suitable for a large-span roof structure. Background technique [0002] At present, the main materials of my country's construction industry are concrete and steel. Whether it is the prefabrication of steel structures or the pouring of concrete structures, they are all industries with high pollution and high energy consumption, which do not meet the national sustainable development goals. [0003] This year, with the introduction of the concept of green buildings, green buildings have received widespread attention from the society. In recent years, light wood structures have become more and more popular among people. However, my country's forest resources are very scarce, and trees have a long lumber cycle, so construction materials are very limited, and the production line is unfavorable for development, so it is difficult to vigorously promote light woo...

Problems solved by technology

[0010] However, the bamboo structures currently in engineering are mainly structures with small spans, but it is difficult to use them in some special forms of space structures such as reticulated shells
