Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] A toothed fastener node, characterized in that: the node includes a rod 1, two semicircular pipe toothed fasteners 2 and bolts 3;

[0020] The two semi-circular pipe toothed fasteners 2 can be fastened to each other to form a circular pipe. The two rods 1 are connected and located in the circular pipe formed by the semi-circular pipe toothed fasteners 2. The two rods are connected by bolts 3. 1 shaft connection is fixed.

[0021] The rod 1 has a bolt hole 5 at the end for the bolt 3 to pass through, and the specific position is aligned with the bolt hole 5 on the semicircular pipe tooth fastener 2, and the end of the rod 1 is raised by sandblasting or a band-shaped groove 4 Friction coefficient, rod 1 is a hollow tube or a solid rod, and the material is not limited to steel;

[0022] The semicircular tube toothed fastener 2 is two serr...

Abstract

The invention relates to a toothed fastener node. The toothed fastener node comprises two rod pieces, two semicircular pipe toothed fasteners and bolts, wherein the two rod pieces are axially and fixedly connected through the toothed fasteners which can be mutually fastened and the bolts, and the force transfer means is clear; the fasteners can be prefabricated in a factory and the node is convenient to install on the site; the installed node has certain rigidity and the safety under a normal use state can be guaranteed; the node is convenient to disassemble, the disassembled components can be repetitively used, and the node is economic and reasonable; the form of the node is simple and the attractiveness of the entire structure is not influenced.

Description

technical field [0001] The invention relates to the technical field of space grid structures and temporary structures, in particular to a toothed fastener node form. Background technique [0002] With the accelerated pace of urbanization and economic development, social living standards have been significantly improved, people's spiritual life has become increasingly rich, and there is an increasing demand for some stages or venues that can hold small gatherings. In order to meet the requirements of a large space, this type of building generally adopts a spatial grid structure, and in order to facilitate temporary activities, there are many applications of temporary structures. Such buildings need to meet the conditions of safety and aesthetics during use, and can be recycled and reused after use to meet economic requirements. In recent years, in the field of spatial grid structures, bolted ball joints and welded hollow ball joints have been widely used. They can be produce...
