Description
Technical field
The invention belongs to unilateral bolt technical fields, and it is tight to be related to a kind of unilateral bolt of overturning deformation type equipped with transverse incision
Firmware.
Background technology
In civil construction project and mechanical erection field, the demand of structural member connection fastening is increasing.It is just general at present
For the bolt used, when implementing connection terminal operation to component, in the operation of component both sides, i.e., staff needs simultaneously
It is inserted into nut bolt in side, then nut is tightened with tool in the other side.This method for fastening connection is simple in structure,
It is easy to operate, carry, but be only applicable in opening section component, and in certain special occasions, such as to closed cross-section structure
When part or the inconvenient component in other side operation are attached fastening, just this common bolt and nut can not be used to connect
Fastening method.Such as：In steel-tube construction and concrete filled steel tube, at beam-column connection, since steel pipe column is to be closed to cut
Face cannot be operated on both sides, unilateral can only connect installation, therefore can not use this common bolt and nut connection fastening
Method carries out fastening installation.Currently, without corresponding unilateral bolt product on domestic market, and published related patents or right
It is very few that shank of bolt weakens excessive or bolt head stress point；Although occurring similar products on overseas market, such product is difficult
Friction-type bolt joint, the synthesis mechanical property of carrying are formed to apply larger pretension to bolt in erection stage
Can be unsatisfactory, it is very limited in Anti-quake Architectural Structure Design application.
The Chinese patent of Publication No. CN103967902A is related to a kind of overturning deformation type unilateral bolt fastener, and overturning becomes
Shape part and jacking sleeve are sleeved on shank of bolt, and mounting hole is stretched into snap bolt, are then tightened nut and are pushed sleeve, overturning is made to become
Shape part ring-type round platform is overturn toward same direction occurs corresponding deformation.Although the fastener can simplify the process and mode of installation,
But its deformation range is smaller, cannot meet fastening strength and stability requirement, can not be suitable for the engineering marketization and use.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind being equipped with transverse incision
Overturning deformation type unilateral bolt fastener.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of overturning deformation type unilateral bolt fastener equipped with transverse incision, which includes snap bolt and edge
Snap bolt is axially sequentially sleeved at auxiliary deformation part, overturning deformable member, jacking sleeve, washer, nut on snap bolt, institute
It is provided in the axial direction with transverse incision on the overturning deformable member stated.Transverse incision is opened in the side of overturning deformable member, and overturning is made to become
The radial section of shape part is in C fonts, to make overturning deformable member have certain plastic deformation ability, when being compressed by external force, energy
It is enough deformed, and so that its outer diameter is increased by deformation, to act directly on connector surface, realize unilateral connection fastening peace
Dress.Jacking sleeve and washer can increase the stiction of entire fastener, improve degree of firmly installing.
Further, the overturning deformable member includes the first cyclic annular round platform and second being set in side by side on snap bolt
Cyclic annular round platform, the miner diameter end of the described first cyclic annular round platform are connected with the miner diameter end of the second cyclic annular round platform.First cyclic annular round platform with

The bigger diameter end of first cyclic annular round platform is adapted.The bigger diameter end that the first cyclic annular round platform is squeezed by the miner diameter end of auxiliary deformation part, makes
The transverse incision of overturning deformable member becomes larger, and then increases the outer diameter of overturning deformable member.
The miner diameter end of the bigger diameter end inner wall and auxiliary deformation part of the first cyclic annular round platform as a preferred technical solution,
Outer wall is adapted.
Further, the snap bolt includes snap bolt bar and is arranged round end spiral shell in snap bolt bar one end
Bolt head, the auxiliary deformation part, overturning deformable member, jacking sleeve, washer and nut are set on snap bolt bar, described
The bigger diameter end of auxiliary deformation part be adapted with snap bolt head.Snap bolt head carries out axial limiting to auxiliary deformation part.
The diameter phase of the outer diameter and snap bolt head of the bigger diameter end of the auxiliary deformation part as a preferred technical solution,
Deng the internal diameter of the miner diameter end of the auxiliary deformation part is adapted with the diameter of snap bolt bar.
Further, the mating surface between the bigger diameter end and snap bolt head of the auxiliary deformation part is plane.
Further, one end of the jacking sleeve is adapted with the bigger diameter end of the second cyclic annular round platform, the other end and pad
Circle is adapted.
Further, which offers connector installation for connector to be fixed on the connector
Hole, the jacking sleeve are adapted with connector mounting hole.Fastener can be used in carrying out unilateral fastening installation to connector.
Further, the outer diameter of the jacking sleeve is less than or equal to the internal diameter of connector mounting hole.
When fastener is installed, auxiliary deformation part, flange deformable member, jacking sleeve, washer, nut are sequentially sleeved in round end spiral shell
On tightening latch, after auxiliary deformation part and overturning deformable member pass through connector mounting hole with first of snap bolt from the side of connector
The other side is reached, nut is turned later, so that it is constantly screwed in and promote jacking sleeve, to make jacking sleeve and auxiliary deformation part
It is common to squeeze overturning deformable member, so that overturning deformable member is deformed, transverse incision becomes larger, while outer diameter increases, and the company of acting on
Unilateral connector fastening installation is realized on fitting surface.
Compared with prior art, the invention has the characteristics that：
1) transverse incision is opened up in an axial direction on overturning deformable member, in the mechanical property for ensureing unilateral bolt fastener carrying
Under the premise of, make overturning deformable member that there is the deformation range of bigger, meets fastening strength and stability requirement, and easy to process and group
Dress, can realize the unilateral terminal operation of automatic batch production and high-effect high-quality, require relatively low to field erected, improve
Building and the efficiency of industry spot installation；
2) bigger diameter end of auxiliary deformation part is plane, and outer diameter is equal with snap bolt head diameter, to make snap bolt
The uniform force of head, while the miner diameter end internal diameter of auxiliary deformation part is matched with the diameter of snap bolt bar, outer wall and the first ring
The bigger diameter end inner wall of shape round platform matches, convenient for keeping higher concentricity when overturning deformable member installation, to make overturning deform
Part uniform force；
3) outer diameter of jacking sleeve is adapted with the bigger diameter end outer diameter of the second cyclic annular round platform, internal diameter and snap bolt shank diameter
It is adapted, the concentricity of snap bolt and connector mounting hole when not only ensure that installation, but also the deformation of overturning deformable member can be made
Uniformly；
4) structure of the invention is compact, size is smaller, it is light-weight, be convenient for carrying, can be carried out in more narrow space
Installation.
