Description
Technical field
The invention belongs to technical field of fastening, more particularly to a kind of expansion fixed bolt.
Background technology
Expansion bolt is the most wide a kind of product of purposes in architectural engineering installation fastener, for by pipeline branch/hang/bracket
Or equipment fixes a kind of special thread connector on the wall, on floor, used on post.By dormant bolt, tube expansion, plain washer,
Spring pad and hex nut composition.In use, workmen drills first with impact drill on matrix, steel expansion bolt is planted
Enter in mounting hole, screwed bolt top nut with wrench, bolt inner termination is moved ahead, outer expansion set pipe and structural matrix are swollen outside for distending
It is tight that corresponding connector is then installed again.Onsite application impact drill needs external electric power source, and whole operation process is various, operating environment
Dirt is floated, influences personnel health, installation exercise efficiency is low, and work intensity is big, engineering time length.
The content of the invention
It is an object of the invention to provide a kind of quick percussion, it is connected firmly, the high expansion fixed bolt of efficiency of construction.
A kind of expansion fixed bolt of the present invention, including expandable nail body and the outer expansion set pipe for being arranged on expandable nail outer body,
It is characterized in that described expandable nail body is nail tip by front end, nail rod and tail end of the centre with reducing are threaded and fallen ladder
The nail tail of staple cap is formed, and percussion component is provided with the nail tail inverted trapezoidal head of a nail, and described outer expansion set pipe is fixedly set in nail
The reducing position of bar, limited step is provided with described nail rod and the junction of nail tail.
Further, described percussion component is by with following closely the plastic housing with groove that pours into an integrated entity of inverted trapezoidal of tail and mounted in modeling
Nitrocotton primer mixture inside shell is formed.
Further, specification of the described tail end with screw rod is M6, M8, M10, M12, M16.
Further, described outer expansion set pipe is round tube, and being provided with the outside of outer expansion set pipe enables outer swollen sleeve stress
Spreading has symmetrical channels, and each symmetrical channels section outer surface is back taper structure, and the tail end of symmetrical channels is provided with evagination Flange.
It is an advantage of the invention that：Operation is without separately plus external connection power source, without drilling, expandable nail inject matrix add with
Basal body binding force, it is functional to realize existing steel expansion bolt institute, is the preferable regeneration product of existing expansion bolt.Whole behaviour
Make process to complete in moment, operational sequence is easy, operating efficiency is high, reduce cost, reduce labor intensity, shortens engineering project builds
If the cycle.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is use state diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
A kind of expansion fixed bolt of the present invention, including expandable nail body and the outer expansion set pipe for being arranged on expandable nail outer body,
It is characterized in that described expandable nail body is nail tip 1 by front end, nail rod 2 and tail end of the centre with reducing carry the He of screw rod 8
The nail tail 4 of the inverted trapezoidal head of a nail 5 is formed, and percussion component, described outer expansion set pipe fixed cover are provided with the nail tail inverted trapezoidal head of a nail 5
Mounted in the reducing position of nail rod 2, limited step 3 is provided with described nail rod 2 and the junction of nail tail 4.
Further, described percussion component by with follow closely tail the plastic housing with groove 7 that pours into an integrated entity of the inverted trapezoidal head of a nail 5 and
Nitrocotton primer mixture 6 inside plastic housing 7 is formed.
Further, specification of the described tail end with screw rod 8 is M6, M8, M10, M12, M16.It is adapted to all size.
Further, described outer expansion set pipe is round tube, and being provided with the outside of outer expansion set pipe enables outer swollen sleeve stress
Spreading has symmetrical channels 10, and each symmetrical channels section outer surface is back taper structure, and the tail end of symmetrical channels is provided with evagination Flange 9.
As shown in Fig. 2 firing primer mixture generation impulse force in plastic housing by firing component, expansion fixed bolt is set to drive outer expansion set pipe
Synchronous to inject in concrete or brick mixed radix body 11, the tail end of symmetrical channels 10 touches concrete or brick provided with evagination Flange 9
The upper surface limited step 3 of mixed radix body 11, expands solid nail and continues to proceed to limited step 3 and be brought into close contact with evagination Flange 9, together
When solid nail rod reducing at big footpath continue to move ahead and wash outer swollen casing part open, make spreading at outer expansion set pipe front opening, make outer swollen
Sleeve pipe expands with back taper structure outer radial concrete or brick mixed radix side, expansion is consolidated the outer expansion set pipe and concrete or brick of nail
Mixed radix body 11 is firmly secured to one.
Front end nail tip 1 is right in hard substrate to go successively in concrete or brick mixed radix body 11 at a high speed and under the condition of high temperature
Front end nail tip 1 forms firm coupling mechanism force.Caused high temperature heat in friction process is penetrated, by front end nail tip 1 and concrete or brick
Melting welding is sintered together mixed radix body 11 securely.
The present invention is injected in concrete or brick mixed radix body 11 by expansion fixed bolt, is added and basal body binding force, is realized
Steel expansion bolt institute is functional, and whole operation process is completed in moment, simple to operate, raising operating efficiency, reduces operation
Cost, mitigate workmen's labor intensity, improve construction speed, being the preferable regeneration product of existing expansion bolt.
The present invention is widely used in architectural engineering installation, public utility works, subway, high ferro project installation, electrically automatic
Change the industries such as project installation, HV＆AC engineering installation, Communication Engineering, be a kind of used in suspension and support and equipment installation fixation
Expansion fixed bolt.
