Bamboo-structure single-layer spherical latticed shell and assembling method

Abstract

The invention relates to a bamboo-structure single-layer spherical latticed shell and an assembling method. The bamboo-structure single-layer spherical latticed shell structurally comprises L bamboo rod pieces, M bamboo connecting pieces and N fixed hinge supports, wherein a single-layer spherical latticed shell main body is formed in a way that two ends of each radial bamboo rod, each weft bamboo rod and each diagonal bamboo rod of the L bamboo rod pieces are connected through the bamboo connecting pieces; the bamboo connecting pieces comprise steel inserting pieces, hollow balls, stiffening steel sheets and bolts; arc-shaped notches are reserved at one ends of the steel inserting pieces and are welded on the hollow balls; bolt holes are reserved at the other ends of the steel inserting pieces, and the bolts are respectively connected to the radial bamboo rods, the weft bamboo rods and the diagonal bamboo rods through the bolt holes; the stiffening steel sheets are welded in connecting positions between the steel inserting pieces and the radial bamboo rods, the weft bamboo rods as well as the diagonal bamboo rods; the upper ends of multiple fixed hinge supports are arranged on the hollow balls of the bamboo connecting pieces which are arranged at the bottom part, and the lower ends of the multiple fixed hinge supports are arranged at the top part of a supporting structure which is arranged at the lower part. The bamboo-structure single-layer spherical latticed shell disclosed by the invention has the advantages that the self weight is light, the construction is convenient, the structural stress is reasonable, the safety is high, the connecting joint is simple and reliable, the maintenance is easy, and environment-friendly effects are realized.

Description

technical field [0001] The invention relates to a bamboo structure single-layer spherical reticulated shell and an assembly method thereof, belonging to the technical field of reticulated shell structures. Background technique [0002] In recent years, in order to meet the requirements of building functions, large-span space structures are increasingly used in engineering practice, such as stadiums that require accommodating a large number of audiences, conference and exhibition centers for academic, cultural, and commercial exchanges, large-scale Departure halls and hangars all require a large event space without exception. The reticulated shell structure, which is formed by arranging rods according to a certain rule and whose main force is characterized by the "film" effect, has become the most widely used due to its large spanning capacity, good rigidity, material saving, variable structure, and strong aesthetics. One of the wide-ranging large-span spatial structures wit...

Problems solved by technology

In the connection of bamboo structures, the common connection methods are tying or mortise and tenon type. Compared with the nodes of steel structure or concrete structure, the connection reliability of bamboo joints using this connection method is low.
