Problems solved by technology

For example, steel splint connection and hidden steel plate connection have high requirements for component manufacturing and processing precision, which may easily cause difficulty in bolt insertion, and cross-grain cracking and damage are prone to occur in glulam in the joint area; planted reinforcement joints have high requirements on the construction environment and require on-site gluing and maintenance, the strength of planting bars is not easy to guarantee, and it takes a long time to occupy the scaffolding, resulting in a longer construction period

Abstract

The invention relates to a node system for a laminated wood space structure, which belongs to the technical field of a building structural member. The node system can be used for rapidly assembling the laminated wood space structure. The node system comprises a plurality of laminated wood components; and the node system also comprises a node steel hub, a plurality f groups of bolt plates and a plurality of bolts; the outer side surface of the node steel hub is detachably connected with a plurality of groups of bolt plates, each group of bolt plates comprises four bolt plates, and a laminated wood component is detachably arranged between every two bolt plates of each group of bolt plates. The node system is simple and convenient in installation process, the application period of a scaffold is short, and the wooden structure can be rapidly spliced on site.

Description

technical field [0001] The invention relates to a joint system for glued wood space structure, which belongs to the technical field of building structural parts. Background technique [0002] At present, bolted plate joints and planted bar joints are mostly used for joint connection of glulam space structures, which have many shortcomings. For example, steel splint connection and hidden steel plate connection have high requirements for component manufacturing and processing precision, which may easily cause difficulty in bolt insertion, and cross-grain cracking and damage are prone to occur in glulam in the joint area; planted reinforcement joints have high requirements on the construction environment and require on-site gluing and maintenance, the strength of planting bars is not easy to guarantee, and it takes a long time to occupy the scaffolding, resulting in a longer construction period. Contents of the invention [0003] The purpose of the present invention is to pr...
