Description
Technical field
The present invention relates to a kind of bolt fasteners can be used in structural member connection fastening carrying out unilateral installation, belong to building
Engineering, mechanical assembly technique field.
Background technology
Current common bolt is divided into screw rod and nut two parts, needs to be inserted into screw rod in side, then will in the other side
Nut is tightened.In this case, staff needs in the operation simultaneously of component both sides.But in certain special occasions, than
Such as closed cross-section member or the component for being inconvenient to touch certain one side, will be unable to be installed using common bolt.
Such as in box column-H profile steel girder connection, since column section is closed cross-section, plain bolt cannot carry out both sides
Operation, can not install.Existing punching bolt technology, very high to the reserved required precision of tube wall both sides bolt hole, alignment is difficult
Degree is very big, and is difficult to apply at side column and corner post node.And in existing unilateral bolt, it cannot generally apply larger preload
Power, and need complicated installation tool and cumbersome installation steps.
Invention content
In view of the above problems, the purpose of patent of the present invention is to provide a kind of Self-resetting unilateral bolt fastener system, realize
Unilateral implementation terminal operation, and the comprehensive mechanical property of bolt carrying is improved, to solve deficiency in the prior art.
To achieve the goals above, solution of the invention is：A kind of Self-resetting unilateral bolt fastener system, including
Four seperated machined shims, snap bolt, nut, sleeve, washers, flat ring of marmem etc..Snap bolt and four
Seperated machined shim carries out location and installation by operating lever and operation top dog.When installation, first by four seperated machined shims
Be assembled into extrudable compound gasket with the flat ring of marmem, then by extrudable compound gasket, sleeve, washer, nut according to
It is secondary to be inserted in operating lever, then operating lever is screwed into the positioning screw hole of snap bolt end, it squeezes compound gasket and at ellipticity and fills in
Then extrudable compound gasket is pushed into bolt hole by bolt hole by operating lever top dog, compound gasket will be in marmem
Lower realization " rebound " is acted on into annular shape from recovery effect.Compound gasket internal projection is caught in table on the inside of bolt hole by pullback operation bar
Face, last mounting gasket and nut, and nut is just twisted, unloading operation bar twists off wabbler with Electric torque wrench, completes eventually
It twists.
It is further：The marmem screw rod has outstanding superelastic properties, is embodied in remaining change
Shape is small, and martensite transformation stress is high, and anti-phase varying stress is higher, ensures that compound gasket has larger return after bolt hole
Multiple power.
Self-resetting unilateral bolt fastener of the present invention is structurally characterized in that：Four split air conditioners process gasket shape complete one
It causes, and corner cut is machined in end, mutually held out against in extrusion process with the extrudable compound gasket for facilitating it to form, and protect
It is fixed to keep steady.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention only needs unilateral operation, can complete the connection terminal operation of bolt.
(2) after installation is complete, bolt head is complete circumferential uniform stressed, and mechanical property is preferable.
(3) after installation is complete, extrudable compound gasket blocks inner wall, plays fastening effect, and fastening effect is good.
(4) after installation is complete, extrudable compound gasket is simple in structure, carrying is uniform, resistance to compression shearing resistance mechanics better performances.
(5) present invention meets Steel Structural Design requirement, can perform well in steel structure node connection, and especially steel pipe is mixed
Xtah Crude Clay structure.
