Soil prefabricated component manufacture just obtains true development before half a century, and prefabricated component really achieves breakthrough development and is
After World War II.At home, the popularization of prefabricated concrete building building, meet country
Energy-saving and emission-reduction, synchronization realize the development strategy of building energy conservation and building industrialization.
Nose cone lifting crab-bolt is a kind of conventional building built-in part, uses round steel forging to form, has multiple load
Lotus grade and length, can be that the difform prefabricated components such as the section of jurisdiction in underground pipeline engineering and pit shaft provide peace
The most reliable, economical and practical solution.During use, first by crab-bolt together with the Bar Anchorage in concrete,
De-molding device is placed, covering crab-bolt when forming one protection chamber to avoid concreting at crab-bolt head.Concrete
After prefabricated component completes, remove de-molding device and expose the head of crab-bolt, use and universal hang first-class lifting appliance and catch on crab-bolt
Complete lifting.
When there being steel inlet part (reinforcing bar, lifting crab-bolt) to be embedded into reinforced concrete segment, it is sometimes desirable to add
Big thickness of concrete cover.And use traditional nose cone lifting crab-bolt crab-bolt must be deepened embedment and could expire
Foot requirement.Now deepen the crab-bolt of embedment and need the biggest de-molding device, be especially 20 tons in maneuvering load group
During crab-bolt with 30 tons.These grooves all must be closed after section of jurisdiction is laid, to guarantee to meet the mixed of regulation
Solidifying protective soil layer thickness.
Utility model content
This utility model aims to provide a kind of tapered anchor bolt and stripper, is particularly well-suited to thickness of concrete cover
Bigger prefabricated pipe section, uses this tapered anchor bolt can shorten crab-bolt length, keeps length of embedment constant, and
Adaptor can be recycled.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of tapered anchor bolt and stripper device, including tapered anchor bolt, stripper and secure component, the described demoulding
Device is provided with chamber resettling, the adaptor of described tapered anchor bolt and the pressed sheet of secure component and is positioned at stripper containing cavity
Indoor.
Further, described tapered anchor bolt includes threaded adaptor and crab-bolt handle, and adaptor includes round platform
Bottom head, cervical region and round platform, rounded nose is similar with tradition lifting crab-bolt head, internal cavity bottom round platform
It is provided with female thread.Crab-bolt handle top is with externally threaded cylinder, and bottom is the cup dolly amplified.Crab-bolt
Bottom the screw-in round platform of handle top in internal cavity.In the case of thickness of concrete cover in section of jurisdiction is relatively big, use
The adaptor of taper and the design of bigger cup dolly, compared with tradition crab-bolt, it is ensured that the anchoring of lifting,
Shorten the length of crab-bolt, and keep length of embedment constant.Compared with tradition crab-bolt head, adaptor passes through interior spiral shell
Stricture of vagina screws in crab-bolt handle and installs boom hoisting, can be recycled.
Further, described tapered anchor bolt uses the casting of CM490 round steel to form.
Further, secure component is made up of pressed sheet and threaded rod.Threaded rod and pressed sheet welding or screw thread are even
Connecing, the former is applicable to the mode of threadingly bar form removal, and the latter is applicable to the side of normal thread bar form removal
Formula.
Further, stripper is divided into left and right two parts of mutual clamping by folding seam, arranges appearance in the middle part of stripper
Receiving adaptor round platform head, the chamber resettling of secure component pressed sheet, chamber resettling two ends connect two through hole respectively.
Further, stripper uses elastomeric material, and this material has resistance to deformation, the excellence such as oil resistant and high temperature resistance
Performance.
During assembling, being broken into two with one's hands by stripper along folding seam, by adaptor round platform head, secure component pressed sheet is put into
In chamber resettling, adaptor cervical region and pressed sheet threaded rod are each passed through through hole and stretch out stripper, stripper 2
Engaging, is then fixed on pressed sheet threaded rod in template with wing nut；After having poured, form removal is i.e.
Removable de-molding device, tapered anchor bolt is i.e. in lifting SBR.
The beneficial effects of the utility model are:
Compared with prior art, tapered anchor bolt provided by the utility model and stripper device, it is adaptable to coagulation
The situation that protective soil layer thickness is bigger, can shorten the length of crab-bolt, and keeps the length of embedment of crab-bolt constant.
The adaptor of this tapered anchor bolt is threaded, can be recycled, reduces cost.Use threaded shank
Pressed sheet make rubber de-molding device fix with template, facilitate the knockout course of prefabricated component.Whole system can be significantly
Improve production efficiency, there is preferable economic benefit.
