A kind of nailing bolt
Technical field
The present invention relates to a kind of nailing bolt.
Background technology
Nailing bolt, is used to suspension bracket is bolted the special fixing bolt that mode is fixed on metope or plate face.All kinds of construction and installation projects propped up for pipeline, pipeline, hold in the palm, suspension bracket and equipment be fixed on the basis of, wall, building pull, generally individually use this nailing bolt mode to construct on column, ceiling.
Nailing bolt is divided into two parts the most along its length, and a part is long column, and long column end is provided with tip, and another part is threaded post, can coordinate with nut screwing clamping.When using nailing bolt, it is possible to use supporting solid nail device, nailing bolt tip is injected in body of wall or plate body.Traditional construction operates needs power supply, impact to bore, build strand hand support carries out construction operation.Operating personnel need to use impact to be drilled on matrix design fixing point and get out the circular hole isometrical with pre-installing expansion bolt, in cultivation after expansion bolt, to be drawn outside bolt by nut with wrench, after bolt end entrance expansion tube distending, swelling is in matrix circular hole again, then implements postorder installation content.Project operation flow process is various, and labor operation intensity is big.Particularly when ceiling upper bore operation, the concrete dust impacted falls to waving, and operating environment deteriorates, and affects operating personnel physically and mentally healthy.Employing expansion bolt fixedly mounts, and operating personnel need to use impact to bore, wrench passes through boring, plant bolt, twist female swelling, install other connector again, and construction operation is loaded down with trivial details, and operating efficiency is low, construction cost is high.
Summary of the invention
The invention aims to overcome disadvantages described above, it is provided that a kind of security is high, easy to operate, the nailing bolt of simple in construction.
A kind of nailing bolt of the present invention, including being divided into two-part nailing bolt along its length, one section is long column, long column end is provided with tip, another section is threaded post, it is characterized in that uniform retaining tooth line at the tip of long column, and it is provided with buffer gasket moving back on tooth line, it is provided with dovetail column cap in the end of described threaded post, the ammunition seat of band dovetail groove it is additionally provided with in described threaded post end, this dovetail groove size matches with dovetail column cap size, it is provided with projectile filling groove in the rear end of ammunition seat, in nitrocotton ammunition press-in projectile filling groove, and at nitrocotton ammunition Surface coating glued membrane, for sealing.
Further, described buffer gasket is circular arch structure.
Further, the ammunition seat of described band dovetail groove uses PBS polyester biodegradated polymer materal.
Further, the ammunition seat of described band dovetail groove and dovetail column cap are moulding by casting.
Further, described nitrocotton ammunition is circular configuration, and is provided with five the most penetrating holes on the section of circular configuration.
The invention have the advantage that multiple functional, easy to operate, program simplifies, operation easily, efficiency increases, saving of labor saves tool, economize on electricity environmental protection, safety and sanitation, cost reduce, improve income.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
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 the nailing bolt being divided into two sections along its length, one section is long column 4, long column 4 end is provided with tip 1, another section is threaded post 5, its threaded post is divided into M6, M8, M10, M12, M16, plurality of specifications size can be provided with by root of hair according to payload, long column 4 distal tip 1 diameter is divided into Ф 3.7, Ф 4.5, Ф 5.2 or Ф 5.5, it is characterized in that uniform retaining tooth line 2 at the tip 1 of long column, and it is provided with buffer gasket 3 on tooth line 2 moving back, its buffer gasket 3 with move back tooth line 2 interference fit, described buffer gasket 3 is circular arch structure.Buffer gasket uses circle arch structure, when installation building substrate injected by nailing bolt, it is ensured that nail end-fire enters to design length thereof, and prevents matrix from injecting excessively with nailing because nailing moment impulse force produces explosion.
The present invention is provided with dovetail column cap 6 in the end of described threaded post 5, the ammunition seat 7 of band dovetail groove it is additionally provided with in described threaded post 5 end, this dovetail groove size matches with dovetail column cap size, it is provided with projectile filling groove 8 in the rear end of ammunition seat 7, in nitrocotton ammunition press-in projectile filling groove 8, and at nitrocotton ammunition Surface coating glued membrane 9, be used for sealing.
This end uses glued membrane to carry out encapsulation process, the most waterproof and dampproof, and product percussion rate is also effectively ensured.
Further, the ammunition seat 7 of described band dovetail groove uses PBS polyester biodegradated polymer materal.Ensure the ammunition seat 7 connecting band dovetail groove when construction application with bolt self falling, after collection can degradation treatment voluntarily, industrial refuse will not be formed and pollute environment.
Further, ammunition seat 7 and the dovetail column cap 6 of described band dovetail groove are moulding by casting.Convenient both are stably connected with, and will not form waste product by self falling because of general External Force Acting.
Further, described nitrocotton ammunition is circular configuration, and is provided with five the most penetrating holes on the section of circular configuration.Increase response area, during percussion injection reaction uniformly, Fast synchronization, produce longitudinal impulse force powerful and stablize, it is ensured that it is specialized factory's offer that nailing bolt is effectively injected in installation matrix wherein five hole nitrocotton ammunitions.After the shaping of nitrocotton ammunition Passivation Treatment, noise is little, stable performance in percussion reaction, tablet assemble and in storage and transport process nonflammable, do not reveal, safe and reliable.
The nailing bolt of different size is furnished with the nitrocotton ammunition of different impulsive force, it is ensured that function nailing bolt the most reliably uses.
The present invention is widely used in the industries such as industry heavy type load installation such as architectural engineering installation, public utility works installation, subway, high ferro project installation, the installation of electric automatization project installation, HV&AC engineering, the installation of communication supervision control engineering, water supply and sewage work installation and all kinds of manufacturing equipment installations.
