Bamboo three-way grid type reticulated 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, in particular to a structure of a main structural spherical reticulated shell 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. Both the prefabrication of steel structures and the pouring of concrete structures are high-pollution, high-energy-consuming industries that do not meet the country's sustainable development goals. [0003] In recent years, with the proposal of the concept of green building, green building has been widely concerned by the society. In recent years, light wood structures have become more and more popular. However, my country's forest resources are very scarce, and the tree growth cycle is long, so building materials are very limited, and production lines are not conducive to development, so it is difficult to vigorously promote light wood structures. At the same time, my ...

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
