Description
【Technical field】
It the utility model is related to a kind of technical field of fastener, the technology neck of particularly a kind of split assembled screw
Domain.
【Background technology】
, need to be when carrying out terminal operation for the plain bolt being made up of screw rod and nut being commonly used
Side insertion screw rod and binding nut, are then tightened nut with instrument in opposite side, and installation requirement installation personnel is simultaneously in structure
The operation of part both sides.But relative to the installation of more typical opening section component, for such as closed cross-section member and inconvenience
Touch wherein for the component of one side, this bolt generally used is using simultaneously inconvenience.Such as concrete filled steel tube,
Beam-column connection etc., because column section is mostly closed section, plain bolt can not be operated on both sides, therefore common side
Method can not be installed.Application of the common expansion one-way bolt because being difficult to bolt pretightening, fastening effect is also unable to reach larger
Design requirement under load.And the reserved required precision of punching bolt-for-bolt hole of the prior art is especially high, in-site installation
Difficulty is big.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of split assembled screw, can
Unilateral implementation terminal operation is realized, is conveniently removed and installed, it is reusable.
To achieve the above object, the utility model proposes a kind of split assembled screw, including upper body, lower body,
Intermediate, cylindrical positioning body and two anti-lift-offs, be equipped with the cylindrical positioning body symmetrical setting upper body and lower
Body, the upper body and lower body are equipped with anti-lift-off in the rear end of cylindrical positioning body, and the front end of the cylindrical positioning body is upper
Intermediate is provided between body and lower body, the upper body, lower body and middle mates form the threaded rod of screw.
Preferably, the free end of the anti-lift-off is cambered surface, the side face of the cylindrical positioning body is without departing from anti-lift-off
Free end.
Preferably, the front end of the intermediate is provided with anti-rotation clamping part, the upper and lower ends of the intermediate are equipped with convex
Rise, the upper body and lower body are provided with the groove being engaged with projection.
The beneficial effects of the utility model:The utility model when in use, stretch into by one end that lower body is provided with to anti-lift-off
In mounting hole, until anti-lift-off is completely out of the inner of mounting hole, then falling body down makes lower body be shelved in mounting hole,
Stretch into mounting hole in one end that upper body is provided with to anti-lift-off, until anti-lift-off is completely out of the inner of mounting hole, then will
Cylindrical positioning body is enclosed on body and lower body, and the diameter of cylindrical positioning body is equal with the diameter of mounting hole, and slides backward
Cylindrical positioning body is contradicted on anti-lift-off until the rear end of cylindrical positioning body, completes assembling, then fixture is enclosed on by upper
Body, lower body and middle mates are formed on the threaded rod of screw, are then screwed on clamp nut and are fixed, with existing skill
Art is compared, and can be realized unilateral implementation terminal operation, conveniently be removed and installed, reusable.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of split assembled screw of the utility model;
Fig. 2 is a kind of rearview of split assembled screw of the utility model;
Fig. 3 is a kind of installation schematic diagram of split assembled screw of the utility model.
In figure:Body under the upper body of 10- mounting holes, 11-, 12-, 13- intermediates, 14- cylindrical positioning bodies, the anti-lift-offs of 15-,
16- anti-rotations clamping part, 17- projections, 18- fixtures, 19- clamp nuts.
【Embodiment】
Refering to Fig. 1, Fig. 2 and Fig. 3, a kind of split assembled screw of the utility model, including upper body 11, lower body 12,
Intermediate 13, cylindrical positioning body 14 and two anti-lift-offs 15, be equipped with the cylindrical positioning body 14 symmetrical setting upper
Body 11 and lower body 12, the upper body 11 and lower body 12 are equipped with anti-lift-off 15 in the rear end of cylindrical positioning body 14, described
The front end of cylindrical positioning body 14 is provided with intermediate 13, the upper body 11, lower body 12 between upper body 11 and lower body 12
It is engaged the threaded rod to form screw with intermediate 13, the free end of the anti-lift-off 15 is cambered surface, the cylindrical positioning body 14
Side face without departing from the free end of anti-lift-off 15, the front end of the intermediate 13 is provided with anti-rotation clamping part 16, the intermediate 13
Upper and lower ends be equipped with projection 17, the grooves that the upper body 11 and lower body 12 are provided with and projection 17 is engaged.
Utility model works process:
A kind of split assembled screw of the utility model in the course of the work, lower body 12 is provided with one end of anti-lift-off 15
Stretch into mounting hole 10, until anti-lift-off 15 is completely out of the inner of mounting hole 10, then falling body 12 down makes lower body 12
It is shelved in mounting hole 10, is stretched into one end that upper body 11 is provided with to anti-lift-off 15 in mounting hole 10, until anti-lift-off 15 is complete
Cylindrical positioning body 14, is then enclosed on upper body 11 and lower body 12, cylindrical positioning body 14 by full the inner for exceeding mounting hole 10
