Technical field
The invention belongs to civil engineering and mechanical connection tightening technology fields, are related to a kind of single side and are put into the spiral shell that can be tightened
Pin device, suitable for carrying out the unilateral connection tightened between structure or component.
Background technique
Currently in civil engineering work and mechanical assembly technique field, to the installation requirements amount of structural elements connection fastening
It is larger.For now, the connection of steel construction generally can be divided into three kinds of welding, riveting and bolting methods, and welded connecting is
More typical connection type in field of civil engineering, but the shake of the north ridge earthquake of the U.S. in 1994 and nineteen ninety-five Japan's Osaka-Kobe earthquake
It is very serious that evil investigation shows that steel frame beam column welding rigid joint destroys, and bolt connection node destruction is more rare.In addition
Welding is also influenced by many extraneous factors, such as welding surroundings and welder technology etc., and quality is difficult to be guaranteed, and spiral shell
Tether and connect relative to welding etc. for other types of attachment, antidetonation, construction quality, speed, in terms of have its significantly
It is advantage and the standardization of bolt factory process, modularization, environmentally protective, meet the development trend of pollution-free industryization building.Just at present
For the bolt generally used, when installation, needs worker in the operation simultaneously of component two sides, i.e., is inserted into the screw rod with nut in side,
With tool, nut is tightened for the other side.This method for fastening connection structure is simple, easy to operate, and load-carrying properties are good, but are only applicable in
In the connection of opening section component, for certain special connections, as in closed cross-section member or be not easy to the component other side into
In the case where row terminal operation, the method for not just being available this conventional bolt and nut connection fastening is attached, and unidirectional
The research and development and application of bolt make the connection of closed cross-section member become reality.But for current published related patents, or
It is that aperture weakens excessively shank of bolt on shank of bolt or bolt end stress is excessively concentrated, holistic resistant behavior is not
Ideal, and complex installation process, are very limited in practical engineering applications.
Summary of the invention

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, to the relevant technologies in the present invention carry out it is clear, completely retouch
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
With reference to Fig. 1~6, a kind of end bracing type unilateral bolt fastener, including it is plain bolt bar 1, taper body 2, interior
Sleeve 3, outer sleeve 4 and rigid washer 5, the plain bolt bar 1 is by hexagon bolt head 1a and screwed shank of bolt structure
At bolt shank diameter is generally 8~20mm.The 2 outer surface front of taper body is divided into conical rear portion and is divided into cylinder, edge
Axial inner is equipped with through-hole, is equipped with internal screw thread in hole, conehead end outer surface uniform ring is furnished with multiple row fin, the taper body 2
It is engaged by screw thread with plain bolt bar 1, the inner sleeve 3 is to stop body 3a, and inner sleeve 3 is leaned on close to shank of bolt tail portion one end
It is close that the one end body 3a is stopped to be equipped with three or four axial slits, stop the length of body 3a breach for the 50%- of 3 height of inner sleeve
60%.
Further, the conehead end of the taper body 2, which can be caught in, stops in body 3a, and the inner diameter edge of blocking body 3a is
Smooth arc-shaped surface, taper body 2 effectively will can stop body 3a to strut as shank of bolt 1 screws to move to screw head direction；
The inner sleeve 3, outer sleeve 4 are connected to one with rigid washer 5 simultaneously, between the outer sleeve 4 and inner sleeve 3 there are
The gap of 2~4mm enables inner sleeve that body end 3a to be stopped freely to be strutted；The inner sleeve stops body 3a central axis and common
Shank of bolt 1 is provided with certain angle, and angle is 85~88 °, make after stopping body 3a to be strutted by taper body 2 can in mounting hole
Wall fits closely；The 2 rear portion cylinder outer diameter of taper body is greater than or equal to 4 outer diameter of outer sleeve and is not more than bolt mounting holes
Diameter；5 internal diameter of rigid washer is less than or equal to 3 internal diameter of inner sleeve；5 external peripheral surface of rigid washer is equipped with symmetrical
Two planar end surfaces can be convenient to use the clamping class tool clamping such as spanner；A kind of end bracing type unilateral bolt fastener
It is installed using torque wrench, installation process is convenient and efficient.
As shown in fig. 7, the entirety for first forming rigid washer 5, outer sleeve 4, inner sleeve 3 covers when concrete operations are implemented
Onto shank of bolt 1, taper body 2 is then screwed to shank of bolt tail portion, fits closely each section component on shank of bolt successively.
Specifically, when two steel structure members connect, phase is reserved on two connected pieces of required connection such as Fig. 8~9
Answer the bolt hole of position corresponding size, when installation is directed at connector, unilateral bolt fastener is completed according to preceding method
Bolt hole is passed through afterwards, and construction personnel tightens bolt head 1a using torque wrench by tool holder rigid washer 5, because of cone
Shape body conehead end surfaces are furnished with multiple row fin along shank of bolt axis direction uniform ring and conehead end is stuck in inner sleeve and stops in body 3a,
Therefore it can make to be not likely to produce relative rotation between taper body 2 and inner sleeve 3, therefore when shank of bolt 1 rotates, taper body 2 will be produced
The raw trend to bolt head 1a axial displacement；It is fixed again because rigid washer 5 is clamped, inner sleeve 3 is fixed, so taper sheath
Body 2 can be screwed in gradually in inner sleeve 3 and strut the blocking body 3a of inner sleeve end along breach, and continuing force makes the flat of taper body
End will stop body 3a to be pressed on steel member inner wall to block bolt bore edges, realize the unidirectional connection installation of bolt.
In conclusion unilateral bolt fastener of the present invention is not necessarily to carry out aperture to closed cross-section, increase on conventional stud bar
Add rigid washer, the components such as inner and outer sleeves and taper body, after bolt is put into bolt hole, construction personnel need to only use from outside
Clamping device fixes rigid washer, while tightening bolt head with torque wrench, and the taper body of shank of bolt tail portion, which screws in, stops body
It is interior that body will be stopped to strut to clamping bolt, realize the installation of unilateral bolt.So the present invention overcomes the deficiencies in the prior art
To have a good application prospect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the scope of the present invention.It is all
Any modification, equivalent replacement, improvement and so within the spirit and principles in the present invention, are all contained in protection scope of the present invention
It is interior.
