Abstract
The utility model relates to a through-wall opposite-pull limiting bolt, which is characterized by including a dual-head screw rod, a pair of inner positioning nuts matched and connected with the two ends of the dual-head screw rod respectively, stud ends coaxially fixed at the outer end parts of the inner positioning nuts, and outer positioning nuts matched and connected with the stud ends. The utility model aims to provide the through-wall opposite-pull limiting bolt, which can be used for accurately limiting and fixing templates.
Description
Technical field
The utility model relates to a kind of through walls to drawing caging bolt.
Background technology
During concrete blinding is built, usually adopt for locating distance between two side templates that stay carries out spacing in the concrete.But because the interior stay of concrete can't be fixed or the position is not accurate enough, and be prone to template dislocation distortion in construction works, the concrete that causes building shaping does not meet construction requirement, causes to do over again, and greatly influences construction quality and progress.
Summary of the invention
It is a kind of through walls to drawing caging bolt that the purpose of this utility model is to provide, and can carry out accurately spacing fixing to template.
The purpose of this utility model is achieved through the following technical solutions: a kind of through walls to drawing caging bolt, it is characterized in that: it comprise double threaded screw, respectively with the two ends of double threaded screw be connected a pair of in setscrew nut, the coaxial double-screw bolt termination of setscrew nut outer end in each and the outside fix nut that is connected with the double-screw bolt termination of being fixedly arranged on.
Using method of the present utility model is as follows: the double threaded screw of selecting to be fit to length, setscrew nut and locking in the double threaded screw two ends are loaded onto, make distance between the outer end of setscrew nuts in two equal the concrete thickness that to build, two side templates then are installed, make two double-screw bolt terminations perpendicular to the respective side template and pass outwards through the through hole of offering on the template, be placed on the double-screw bolt end portion locking outside fix nut in the template outside afterwards, the template medial surface is abutted on the outer end of interior setscrew nut, and the lateral surface of template abuts on the inner end of outside fix nut.
The utility model has also carried out following improvement:
In described the periphery wall of setscrew nut in the form of a truncated cone and the external diameter of its outer end greater than the external diameter of inner end, so that concreting is disassembled down interior setscrew nut after finishing; The inner end of described outside fix nut has the expansion outer peripheral edges.Can more effectively carry out the clamping location like this, cover in the through hole on the template simultaneously, avoid from the through hole spillage to template.
Better fastening for template is carried out, the outer end of described outside fix nut is connected with bolt-type lockset depending post; Described bolt-type lockset depending post is provided with the pin hole with the axis normal of outside fix nut.
Described double-screw bolt termination is the symmetrical little raised line of axis of symmetry at it near being provided with double-screw bolt termination central axis on the end periphery wall of interior setscrew nut one side, carries out quickly dismantled to cooperate the internal setscrew nut of dismantling device.
The peripheral part of described double threaded screw also is arranged with the sleeve pipe between the setscrew nut in two, after concreting is finished, can very easily double threaded screw be taken out, and reuses.
Compared to prior art, advantage of the present utility model is:
(1) by cooperating between double threaded screw and interior setscrew nut, can carry out spacingly accurately to two side templates, cooperate with the outside fix nut by interior setscrew nut, double-screw bolt termination, effectively fixed form;
(2) simple for structure, cooperate closely, be easy to make.

The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
As Fig. 1, Fig. 2 with to Figure 3 shows that the utility model provides a kind of through walls to drawing the embodiment schematic diagram of caging bolt.It comprises double threaded screw 1, respectively with the two ends of double threaded screw 1 be connected a pair of in setscrew nut 2, the coaxial double-screw bolt termination 3 of setscrew nut 2 outer ends in each and the outside fix nut 4 that is connected with double-screw bolt termination 3 of being fixedly arranged on.
In described the periphery wall of setscrew nut 2 in the form of a truncated cone and the external diameter of its outer end greater than the external diameter of inner end, the inner end of described outside fix nut 4 has the expansion outer peripheral edges.
The outer end of described outside fix nut 4 is connected with bolt-type lockset depending post 5; Described bolt-type lockset depending post 5 is provided with the pin hole 5-1 with the axis normal of outside fix nut 4.
Described double-screw bolt termination 3 is the symmetrical little raised line 3-1 of axis of symmetry at it near being provided with double-screw bolt termination 3 central axiss on the end periphery wall of interior setscrew nut 2 one sides.
The peripheral part of described double threaded screw 1 also is arranged with the sleeve pipe between the setscrew nut 26 in two.
