A kind of nailing bolt
Technical field
The present invention relates to a kind of nailing bolt.
Background technology
Nailing bolt, it is the special fixed spiral shell being fixed on for suspension bracket to be bolted to mode in metope or plate face
Bolt.On the basis of being fixed in all kinds of construction and installation projects for pipeline, pipeline branch, support, suspension bracket and equipment, wall, building pull, be vertical
Generally constructed on post, on ceiling using this nailing bolt mode.
Nailing bolt is typically divided into two parts along its length, and a part is long column, and long column end is provided with tip, another
Part is threaded post, and cooperation can be tightened with nut.When using nailing bolt, supporting solid nail device can be used, by nailing
Bolt tip is injected in wall or plate body.Traditional construction, which operates, which needs power supply, impact drill, builds strand hand support carries out construction work
Industry.Operating personnel need to use impact drill to be designed in matrix and the circular hole isometrical with prepackage expansion bolt are drilled out on fixing point, in cultivation
After expansion bolt, then it will be drawn by nut outside bolt with wrench, swelling is in matrix circular hole after bolt end enters expansion tube distending
It is interior, then implement postorder installation content.Project operation flow is various, and labor operation intensity is big.Particularly make in ceiling upper bore
During industry, impact the concrete dust got off and fall and wave, operating environment deteriorates, and influences operating personnel's physical and mental health.Using expansion
Bolt is fixedly mounted, and operating personnel, which need to pass through using impact drill, wrench, to drill, plants bolt, twisting female swelling, installing other connections again
Part, construction operation is cumbersome, and operating efficiency is low, construction cost is high.
The content of the invention
The invention aims to overcome disadvantages described above, there is provided a kind of safe, easy to operate, simple in construction penetrates
Oncomelania bolt.
A kind of nailing bolt of the present invention, including it is divided into two-part nailing bolt along its length, one section is long column,
Long column end is provided with tip, and another section is threaded post, it is characterised in that the uniform retaining tooth line at the tip of long column, and moving back tooth
Line is provided with buffer gasket, is provided with dovetail column cap in the end of described threaded post, band is additionally provided with described screw thread column end
The ammunition seat of dovetail groove, this dovetail groove size match with dovetail column cap size, and dress is provided with the rear end of ammunition seat
Drug slot, in nitrocotton ammunition press-in projectile filling groove, and in nitrocotton ammunition Surface coating glued membrane, for sealing.
Further, described buffer gasket plays arch structure to be circular.
Further, the ammunition seat with dovetail groove uses PBS polyester biodegradated polymer materals.
Further, the ammunition seat with dovetail groove and dovetail column cap are moulding by casting.
Further, described nitrocotton ammunition is circular configuration, and provided with uniformly penetrating on the section of circular configuration
Five holes.
It is an advantage of the invention that:Multiple functional, easy to operate, program simplifies, operation is light, efficiency increases, saving of labor saves tool,
Economize on electricity environmental protection, safety and sanitation, cost reduce, improve income.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of nailing bolt of the present invention, including it is divided into two sections of nailing bolt along its length, one
Section is long column 4, and the end of long column 4 is provided with tip 1, and another section is threaded post 5, and its threaded post is divided into M6, M8, M10, M12, M16, can
Root of hair is provided with plurality of specifications size according to payload, and the diameter of 4 distal tip of long column 1 is divided into Ф 3.7, Ф 4.5, Ф 5.2 or Ф
5.5, it is characterised in that the uniform retaining tooth line 2 at the tip 1 of long column, and buffer gasket 3 is provided with tooth line 2 is moved back, it delays
Rush packing ring 3 and be interference fitted with moving back tooth line 2, described buffer gasket 3 plays arch structure to be circular.Buffer gasket uses circular arch camber knot
Structure, when nailing bolt injects installation building substrate, ensure that nail end-fire enters to design length thereof, and prevent matrix because of nailing moment
Impulse force produces explosion and nailing is injected excessively.
The present invention is provided with dovetail column cap 6 in the end of described threaded post 5, and band is additionally provided with the described end of threaded post 5
The ammunition seat 7 of dovetail groove, this dovetail groove size match with dovetail column cap size, are provided with the rear end of ammunition seat 7
Projectile filling groove 8, in nitrocotton ammunition press-in projectile filling groove 8, and in nitrocotton ammunition Surface coating glued membrane 9, for sealing.
This end carries out encapsulation process using glued membrane, not only waterproof and dampproof, and product percussion rate is also effectively ensured.
Further, the ammunition seat 7 with dovetail groove uses PBS polyester biodegradated polymer materals.Ensure
The ammunition seat 7 of connect band dovetail groove in construction application with bolt self falling, after collection can voluntarily degradation treatment, no
Industrial refuse pollution environment can be formed.
Further, the ammunition seat 7 with dovetail groove and dovetail column cap 6 are moulding by casting.Both convenient stabilizations
Connection, will not because general external force act on and self falling formed waste product.
Further, described nitrocotton ammunition is circular configuration, and provided with uniformly penetrating on the section of circular configuration
Five holes.Increase response area, fire react during injection uniformly, Fast synchronization, it is powerful and stablize to produce longitudinal impulse force, guarantor
Card effectively injects nailing bolt in installing matrix that wherein five hole nitrocotton ammunitions provide for specialized factory.Nitrocotton ammunition
After Passivation Treatment shaping, noise is small, stable performance for percussion reaction, nonflammable in tablet assembling and storage and transport process, do not reveal, pacify
It is complete reliable.
The nailing bolt of different size is furnished with the nitrocotton ammunition of different impulsive forces, it is ensured that function nailing bolt effectively may be used
By using.
The present invention is widely used in architectural engineering installation, public utility works installation, subway, high ferro project installation, electrically
Automation engineering installation, HV&AC engineering installation, the installation of communication supervision control engineering, water supply and sewage work installation and all kinds of manufacturing industry are set
The industries such as the industry heavy type load installation such as standby installation.
