Embodiment 1

[0032] see Figure 1-Figure 7 , the present embodiment 1 provides a method for installing a large-diameter hollow rivet for bamboo and wood structures, which is characterized in that it includes:

[0033] Step S1: Drill holes on the multi-layer connection plate to be riveted to form a through hole 2, insert the matching hollow rivet 3 into the through hole 2, and ensure that both ends of the hollow rivet 3 pass through the multi-layer connection plate at a certain distance.

[0034] Specifically, the multi-layer connecting board used in this embodiment is a three-layer bamboo-wood connecting board structure, including: an upper connecting board 101, a middle connecting board 102, and a lower connecting board 103; the hollow core used in this embodiment The rivet 3 is made by cutting the steel pipe 8 into a suitable length by cutting equipment, and it is necessary to ensure that no cracks are generated during the cutting process, and then it is necessary to use sandpaper to po...

Abstract

The invention discloses a mounting method of a large-diameter hollow rivet for a bamboo structure. The mounting method comprises the steps that S1, the hollow rivet is inserted into a through hole; S2, the upper end and the lower end of the hollow rivet are sleeved with gaskets; S3, the vertical position of the hollow rivet is adjusted; S4, a reamer is used for reaming one end of the hollow rivet; S5, the reamed end is pressurized to form a turned edge, and the turned edge is installed on the corresponding gasket in a pressing mode; and S6, the other end of the hollow rivet is sequentially subjected to reaming, pressurizing and edge turning treatment through the method from the step S4 to the step S5. Through radial expansion of the hollow rivet, the problem of initial pores existing in the bamboo structure for a long time is greatly reduced, and the initial rigidity of a joint is improved. By adopting a hollow rivet connecting piece, a metal connecting piece is weakened, so that the metal connecting piece deforms firstly, and splitting of a bamboo board is effectively avoided while the joint obtains good ductility.

Description

technical field [0001] The invention relates to the technical field of fastener installation, in particular to a large-diameter hollow rivet installation method for bamboo and wood structures. Background technique [0002] As an important part of green buildings, modern bamboo and wood structures meet the requirements of sustainable development. They have begun to rise in the past ten years. Beautiful and changeable, renewable resources and other significant advantages. Due to the limitation of the transverse fracture performance of bamboo and wood materials, the strength and stiffness of the node domain often play a controlling role on the overall performance of the structure. At the same time, the requirements for simplified assembly and construction of bamboo and wood structures also put forward new requirements for the processing convenience and performance reliability of the node domains of modern bamboo and wood structures. [0003] The commonly used connection forms...
