Utility model content
The purpose of this utility model is to provide a kind of reducing through-wall bolts, mentioned above in the background art existing to solve
The bolt of both ends mantle fiber, that is, split bolt are generally used in the through-wall bolt used, also useful band steel both ends stay slot hole to use
Wedge-shaped iron is inserted into fixed wedging.Active wall-thorugh crew-bolt device includes the through-wall bolt bar of a TBE (threaded both ends), is set to through walls
Two horn sockets at shank of bolt both ends, two horn sockets outsides are respectively equipped with two fastening bolt bars, are set in horn socket
Iron core, iron core are equipped with internal thread through hole, and iron core peripheral hardware platform taper nylon contact layer, nylon contact layer and iron core are into a single integrated structure,
Iron core is being equipped with outer-hexagonal nut close to horn socket bottom end, assembles cumbersome problem.
To achieve the above object, the utility model provides the following technical solutions：A kind of reducing through-wall bolt, including the first spiral shell
The right end of bar, first screw rod is provided with lead screw, and the right end of the lead screw is provided with the second screw rod.
Preferably, the outer diameter of first screw rod is bigger than the outer diameter of the second screw rod.
Preferably, first screw rod, lead screw and the second screw rod are an integral structure.
Preferably, the lead screw is pyramidal structure.
Compared with prior art, the utility model has the beneficial effects that：A diameter of 24 screw in reducing through-wall bolt one end
Size, a diameter of 16 screw of the other end, have among it one section arrive the gradually smaller lead screw of the other end, make screw rod than previous spiral shell
Bar is light, easily quick in use, can not only reduce the loss of normal lead screw in construction, in cooperation new casing
It uses, increases the globality to formwork structure, rigidity and intensity, not only improve the work rate of worker, but also reduce production cost,
Moreover, being greatly reduced on consumptive material.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：The first screw rods of 1-, 2- lead screws, the second screw rods of 3-.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of reducing through-wall bolt, including the first screw rod 1,
The right end of first screw rod 1 is provided with lead screw 2, and the right end of lead screw 2 is provided with the second screw rod 3.
In the present embodiment, it is preferred that the outer diameter of the first screw rod 1 is bigger than the outer diameter of the second screw rod 3,1 side wall of the first screw rod
On be M24 standard threads, match corresponding hex nut, on 3 side wall of the second screw rod is the T16 straight threads of extrusion molding, is matched
Corresponding wing nut, since the left end of bolt entirety is thicker than right end, so the diameter of thread of left end is more straight than the screw thread of right end
Diameter will greatly, and work so is also more stablized.
In the present embodiment, it is preferred that the first screw rod 1, lead screw 2 and the second screw rod 3 are an integral structure, which is integrally
It is process by the turning and tapping of axis, simple in structure and easy to process, globality is strong.
In the present embodiment, it is preferred that lead screw 2 is pyramidal structure, and entire bolt can be made lighter than previous bolt,
It is easily quick in use, the loss of normal lead screw in construction can be not only reduced, new casing can also be coordinated to use, added
Greatly to the globality of formwork structure, rigidity and intensity.
Operation principle：When the utility model is used, user is first placed on template the side of the first screw rod 1, then
Template is placed on the side of the second spiral shell 3, and the big end by tapping bolt can make bolt quickly pass through template, wherein first
The outer diameter of screw rod 1 is bigger than the outer diameter of the second screw rod 3, and on 1 side wall of the first screw rod is M24 standard threads, matches corresponding hexagonal
Nut, on 3 side wall of the second screw rod is the T16 straight threads of extrusion molding, matches corresponding wing nut, due to a left side for bolt entirety
End is thicker than right end, so the diameter of thread of left end is bigger than the diameter of thread of right end, work so is also more stablized, simultaneously
Lead screw 2 is pyramidal structure, and entire bolt can be made lighter than previous bolt, easily quick in use, not only may be used
To reduce the loss of normal lead screw in construction, new casing can also be coordinated to use, increase the globality to formwork structure, rigidity
It is fixed again with corresponding connector gasket in the upper end of bolt with intensity, and nut check, reinforcing template, if to extract out
Through-wall bolt only needs the small end head for tapping bolt that easily bolt can be extracted out, but the fulcrum of its support construction is constant,
The stability etc. for increasing formwork structure not only greatly improves the construction efficiency of worker during its use, but also big
Big saving product lead time and production and processing cost, entire workflow terminates.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
