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.
