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
The present invention relates to spatial mesh structure and temporary structure technical field, be specifically related to a kind of profile of tooth fastener joint form.
Background technology
Along with quickening and the expanding economy of urbanization process step, social life level has had significant raising, and people's cultural life becomes increasingly abundant, and can hold the stage of small gatherings or the demand of venue more and more to some.For meeting the requirement of large space, the general spatial mesh structure that adopts of this type of building, for convenience of provisional activity, temporary structure application is also more.This type of building need to meet the conditions such as safe, attractive in appearance in use, and can after use, realize recycling, meets economy requirement.In recent years, in spatial mesh structure field, bolted spherical node and the application of welded hollow spherical joints form are more, and it can produce in batch production, applied widely, but bolted spherical node part is more, manufacturing cost is larger; Welded spherical node requires high to processing technology, difficulty of construction is large.In temporary structure, fastener type and bowl fastening type node are widely used, and having can prefabrication, is easy to the advantages such as installing/dismounting.But the non-axle center of member of fastener type node connects, joint structure exists eccentric, stressed unreasonable; Bowl fastening type node needs bowl button to be welded on rod member in forming process, and recycling rate of waterused is lower.
Summary of the invention
The object of the invention is to improve above not enough, propose a kind of reasonable stress, can reuse, be applicable to the joint form of spatial mesh structure and temporary structure; The principal character of this joint form is two rod members to be connected reliably with fastener by bolt, and type of attachment is that axle center connects, and force path is clear and definite; Fastener can prefabrication, on-the-spot easy for installation; Node after installation has certain rigidity, can ensure the safety under normal operating condition; Convenient disassembly, the member after dismounting can reuse, economical rationality; The form of node is succinct, does not affect integrally-built aesthetic property.
For achieving the above object, the technical solution used in the present invention is a kind of profile of tooth fastener node, and this node comprises rod member, two semi-circular tube profile of tooth fasteners and bolt.
This profile of tooth fastener node is connected and fixed two rod member axle center by two profile of tooth fasteners that can mutually fasten and bolt.
Described rod member has the bolt hole passing through for bolt endways, and particular location aligns with fastening bolt hole, and rod member end improves friction factor by sandblast or banded groove, and rod member form can be hollow section or solid hopkinson bar, and material is not limited to steel.
Described profile of tooth fastener is two semi-circular tubes with sawtooth, can prefabrication, the upper and lower side of pipe has the bolt hole passing through for bolt, semi-circular tube is inner improves friction factor by sandblast or fillet, a pipe with bolt hole of composition after two profile of tooth fasteners fasten via sawtooth, its internal diameter is identical with the external diameter of connecting rod.Its effect is sawtooth by fastening and the friction of profile of tooth fastener inwall and rod member provides supporting capacity for node.
Described bolt can be connected rod member tighten with profile of tooth fastener with the bolt hole on profile of tooth fastener through rod member, completes the installation of node and can dismantle.Its effect is to provide supporting capacity for node.
Compared with prior art, the present invention has following useful feature.
Joint form simple structure, attractive in appearance, part is less and can prefabrication, precision is guaranteed, can reduce construction error.
2. construction and installation are convenient, and rod member axle center connects, and force path is clear and definite, has supporting capacity.
3. use after function in structural constraint, the convenient disassembly of this node, the rod member after dismounting and fastener can reuse, and economy has good guarantee.
