Abstract
The utility model discloses an anchor crab -bolt, it includes the screw rod, and the lower part of screw rod is the linkage segment with bottom hole connected, is provided with the technology blind hole on the screw rod up end relative with the linkage segment, is provided with pombe or metal rod in the technology blind hole, and the external diameter of pombe or metal rod is interference fit with the aperture of technology blind hole, the lower part of pombe or metal rod divides the setting to be in in the technology blind hole, expose at the upper end top of pombe or metal rod the height is set for to the screw rod up end. The utility model discloses can not destroy the anticorrosive coating of crab -bolt, it is simple to use, with low costs, prolonged the life of crab -bolt.
Description
Technical field
The utility model relates to a kind of anchoring crab-bolt.
Background technique
Crab-bolt at the bottom of rear expansion is the anchoring piece that construction industry is commonly used, usually the parts such as screw rod, expansion sleeve are provided with, be arranged on expansion sleeve bottom expansion change in pre-processed boring and implement anchoring greatly, the sidewall extrusion to boring bottom while its expansion, and then realize the fixing of crab-bolt.And when crab-bolt puts into boring, usually need to knock crab-bolt head with metal hammer, utilize the impact strength of metal hammer crab-bolt to be pushed in boring.When impacting, metal hammer and crab-bolt head impact, the unavoidable coating for protection against corrosion destroying crab-bolt head, causes easily being etched in crab-bolt using process afterwards.
Model utility content
For solving the problem, the purpose of this utility model is to provide a kind of anchoring crab-bolt, and this crab-bolt avoids metal hammer and directly impacts this crab-bolt head, and then it also avoid the destruction of its anticorrosive coat, prevents from being corroded in crab-bolt use afterwards.
For achieving the above object, a kind of anchoring crab-bolt disclosed in the utility model, it comprises screw rod, the bottom of screw rod is the linkage section be connected with bottom outlet, the screw rod upper-end surface relative with linkage section is provided with technique blind hole, technique blind hole is provided with Metal Ball or metal bar, the external diameter of Metal Ball or metal bar and the aperture of technique blind hole are interference fit; The lower part of described Metal Ball or metal bar is arranged in described blind hole, and described screw rod upper-end surface setting height is exposed at the top, upper end of described Metal Ball or metal bar.
Further, described Metal Ball or metal bar are made up of stainless steel material or aluminum alloy.
Further, described crab-bolt is crab-bolt or expansion anchor at the bottom of rear expansion.
Further, the diameter of described Metal Ball or metal bar is the 0.25-0.75 of described screw diameter.
During use, stainless steel (or aluminum alloy) ball or stainless steel (or aluminum alloy) rod are put into technique blind hole, use the upper end of hammer stainless steel (or aluminum alloy) ball or stainless steel (or aluminum alloy) rod, stainless steel (or aluminum alloy) ball or stainless steel (or aluminum alloy) rod are inserted in blind hole, owing to being interference fit between the two, in the process impacted thus, stainless steel (or aluminum alloy) ball or barred body pushing tow crab-bolt and are constantly entered in bottom outlet.After this work completes, stainless steel (or aluminum alloy) ball or rod are embedded in blind hole.The utility model can not destroy the anticorrosive coat of crab-bolt, and use simple, cost is low, extends the working life of crab-bolt.
Accompanying drawing explanation
Fig. 1 is the structural representation of fastening anchor bolt in embodiment;
Fig. 2 is the close-up schematic view of technique blind hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As illustrated in fig. 1 and 2, a kind of anchoring crab-bolt, it comprises screw rod 10, the bottom of screw rod 10 is the linkage section 3 be connected with bottom outlet, screw rod 10 upper-end surface relative with linkage section 3 is provided with technique blind hole 1, technique blind hole 1 is provided with Metal Ball 2, the external diameter of Metal Ball 2 and the diameter of technique blind hole 1 are interference fit; The lower part of Metal Ball 2 is arranged in technique blind hole 1, and screw rod 10 upper-end surface setting height is exposed at the top, upper end of Metal Ball 2.Metal Ball 2 is made up of stainless steel (or aluminum alloy) material.Crab-bolt is crab-bolt at the bottom of rear expansion, and it comprises the expansion sleeve 5 expanding the end.The diameter of Metal Ball 2 is 1/4 of screw rod 10 diameter.
Below only describe several preferred embodiments of the application by reference to the accompanying drawings, but the application is not limited thereto, every those of ordinary skill in the art are under the spirit not departing from the application, and any improvement made and/or distortion, all belong to the protection domain of the application.
