Abstract
The utility model discloses a removable type is glued sticking and is expanded end crab -bolt and anchor structure thereof, wherein (b) removable type is glued sticking and is expanded end crab -bolt, it includes the screw rod, the screw rod lower part be the linkage segment with bottom hole connected, screw rod upper portion be with nut complex fastening section, the middle part of screw rod be the changeover portion, all is provided with the screw on the outer circumference of linkage segment and fastening section, the changeover portion is big -end -up's frustum personally experiences sth. Part of the body, the minimum diameter that the frustum was personally experienced sth. Part of the body is greater than the external diameter of linkage segment, be provided with on the linkage segment and expand dead knife head and awl mother. When crab -bolt in this anchor mechanism is damaged, can screw out the bolt, reinsert new bolt and replace, avoid the trouble that the secondary punched among the prior art, original awl mother can continue the use simultaneously, has both improved work efficiency by the cost is reduced.
Description
Technical field
The utility model relates to the gluing mould of a kind of exchangeable and expands end crab-bolt and anchor structure thereof.
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.
During construction, put crab-bolt place in preparation and bore a straight hole, re-use mould bottom expanding drill clear hole after reaming bottom straight hole; Use instrument is by conical head and the sleeve of coupling bottom outlet or cut bed plate head and knock in bottom outlet, and makes sleeve or cut bed plate head along conical head spreading, is formed to be similar to mould and to expand end crab-bolt effect, reserves one section of screw rod, can carry.
The shortcoming of this kind of crab-bolt anchor structure is, is damaged or corrosion etc. crab-bolt, cannot change this crab-bolt, in other position redrillings, can only place crab-bolt at the bottom of new expansion.
Model utility content
For solving the problem, the purpose of this utility model is to provide the gluing mould of a kind of exchangeable to expand end crab-bolt and anchor structure thereof, when the crab-bolt damage in this anchoring mechanism or corrosion, bolt can be screwed out, reinsert new bolt to replace, avoid the trouble of secondary punching in prior art, original cone nut can continue to use simultaneously, has both increased work efficiency by reducing cost.
For achieving the above object, the gluing mould of a kind of exchangeable disclosed in the utility model expands end crab-bolt, it comprises screw rod, screw rod bottom is the linkage section be connected with bottom outlet, screw rod top is fastening section with nut screw connection, and the middle part of screw rod is changeover portion, and the excircle of described linkage section and fastening section is provided with screw thread, described changeover portion is up big and down small cone table, and the minimum diameter of described cone table is greater than the external diameter of described linkage section; Described linkage section is provided with and expands bed plate head and cone nut.
Further, the inside angle of inclination in the frustum face of described changeover portion is 5-30 degree.
Adopt the anchor structure of crab-bolt at the bottom of above-mentioned expansion, at the bottom of described expansion, the linkage section of crab-bolt stretches in the bottom outlet of basic material, and the changeover portion of described screw rod and the outer surface of linkage section all scribble anti-corrosive properties oiling agent; Anchor adhesive is filled with between described expansion bed plate head and bottom outlet.
Further, described anti-corrosive properties oiling agent is vaseline or butter etc.
Further, the gap filling between described bottom outlet and described screw rod has anchor adhesive.
By smearing anti-corrosive properties oiling agent at the outer surface of changeover portion and linkage section; screw rod is goed deep into Bottom bore portion by oiling agent effectively and anchor adhesive isolate; place anchor adhesive and can either ensure that bonding is stressed; cone nut can be protected again and expand bed plate head and can not produce corrosion; thus when the fastening segment structure of this crab-bolt damages; easily screw rod is spun out from bottom outlet, do not need to punch separately.Maintenance cost is low thus, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of fastening anchor bolt in embodiment;
Fig. 2 is the schematic diagram of anchor structure in embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the gluing mould of a kind of exchangeable expands end crab-bolt, it comprises screw rod, screw rod bottom is the linkage section 3 be connected with bottom outlet, screw rod top is fastening section 1 that coordinates with nut 6, and the middle part of screw rod is changeover portion 2, and the excircle of linkage section 3 and fastening section 1 is provided with screw thread, changeover portion 2 is up big and down small cone table, and the minimum diameter of cone table is greater than the external diameter of linkage section 3; Linkage section 3 is provided with and expands bed plate head 4 and cone nut 5.The inside angle of inclination in the frustum face of changeover portion 2 is 6.
As shown in Figure 2, adopt the anchor structure of crab-bolt at the bottom of above-mentioned expansion, the linkage section 3 and the changeover portion 2 that expand end crab-bolt stretch in the bottom outlet 9 of basic material, and the changeover portion 2 of screw rod and the outer surface of linkage section 3 all scribble anti-corrosive properties oiling agent 7; Expand between bed plate head 4 and bottom outlet 9, between bottom outlet 9 and screw rod linkage section 3/ changeover portion 2, be filled with anchor adhesive 8.Anti-corrosive properties oiling agent 7 is vaseline or butter etc.Anchor adhesive 8 and screw rod are isolated by the anti-corrosive properties such as vaseline or butter oiling agent.Thus when ensureing dismounting, screw rod can screw out smoothly from bottom outlet.
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.
Claims (5)
