Detailed description of the invention
Core of the present utility model there is provided a kind of water-proof bolt, partly can reuse, save material, and improves waterproof, anti-permeability performance.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1-Fig. 4, the operating diagram of a kind of water-proof bolt that Fig. 1 provides for the utility model embodiment; Fig. 2 is the demolishing process figure of the water-proof bolt in Fig. 1; Fig. 3 is the structural representation after the water-proof bolt in Fig. 1 is removed; The sectional drawing of a kind of water-proof bolt that Fig. 4 provides for the utility model embodiment.
The utility model embodiment provides a kind of water-proof bolt, comprises intermediate connector 1, positioning component 2 and clamp nut 3; Wherein, intermediate connector 1 entirety is rod-like structure, and be provided with sealing piece 101, sealing piece 101 can be welded on the centre position of intermediate connector 1, and the two ends of intermediate connector 1 are provided with the first threaded portion 102; Positioning component 2 comprises the second threaded portion 201, location division 202, fastening screw 203 and moment of torsion applying unit 204 by one end successively to the other end, second threaded portion 201 is threaded with the first threaded portion 101, and location division 202 is for unidirectional restriction template 5 axially moving at positioning component 2; Fastening screw 203 is connected with location division 202, can through the installing hole of template 5; The free end of fastening screw 203 is provided with moment of torsion applying unit 204, for applying moment of torsion to positioning component 2, positioning component 2 is rotated; Clamp nut 3 is tightened with fastening screw 203 and is coordinated.
Operating principle and the process of above-mentioned water-proof bolt are as follows: as shown in Figure 1, second threaded portion 201 of two positioning components 2 is threaded with first threaded portion 101 at intermediate connector 1 two ends respectively, afterwards, two templates 5 are arranged on respectively on two fastening screws 203, and the plate face of template 5 is contacted with location division 202, clamp nut 3 is tightened on fastening screw 203, by clamp nut 3, template 5 is fastened on positioning component 2, the spacing of the locating surface of two location divisions 202 is the size of construction requirement, i.e. the thickness of structural concrete; After fixing template 5, to concreting between two templates 5, concrete coagulation is shaped to structural concrete, dismantles, as shown in Figure 2 to template 5 and water-proof bolt, clamp nut 3 is screwed down from fastening screw 203, take off template 5, use instrument applies moment of torsion to moment of torsion applying unit 204, and positioning component 2 is reversely rotated, second threaded portion 201 is separated with the first threaded portion 101, thus is pulled down by positioning component 2; Now, intermediate connector 1 is stayed in structural concrete, and as shown in Figure 3, positioning component 2 leaves space after dismantling on structural concrete, uses concrete by complete for this space filling, is completely enclosed within structural concrete by intermediate connector 1.
Can be found out by said process, after water-proof bolt dismounting, positioning component 2 can reuse, and therefore, saves material, decreases the waste of resource; Further, after dismounting, intermediate connector 1 is completely enclosed within structural concrete, intermediate connector 1 not with extraneous contact, then water can not ooze out by the gap between concrete and intermediate connector 1, thus improves the waterproof of water-proof bolt, impervious performance, improves construction quality.
As depicted in figs. 1 and 2, in the present embodiment, water-proof bolt also comprises pad 4, during work, after template 5 being arranged on fastening screw 203, pad 4 is enclosed within fastening screw 203, screwing on again clamp nut 3, by arranging pad 4, loosening of clamp nut 3 can be prevented, and clamp nut 3 can be made stressed evenly, and the installing hole place of template 5 to be sealed.
As shown in Figure 4, the first threaded portion 101 is screwed pipe, and correspondingly, the second threaded portion 201 is threaded rod; Or the first threaded portion 101 is threaded rod, the second threaded portion 201 is screwed pipe.As long as removably connecting of intermediate connector 1 and positioning component 2 can be realized.
Further, as shown in Figure 2 and Figure 4, in the present embodiment, location division 202 is circular cone, and the tip of circular cone is connected with the second threaded portion 201, and the planar ends of circular cone is connected with fastening screw 203.The object of such setting is: improve location division 202 structural strength on the one hand, on the other hand, positioning component 2 is facilitated to dismantle, and after positioning component 2 disassembles, structural concrete stays the space of taper, increase the distance between intermediate connector 1 and structural concrete outside wall surface, prevent infiltration better.Certainly, location division 202 can also be cylindrical piece or laminated structure, can to the positioning instant of template 5 as long as can realize.
As shown in Figure 4, present embodiments provide a kind of concrete intermediate connector 1, the interlude of intermediate connector 1 is external surface is smooth round bar or pipe, and round bar or pipe weld sealing piece 101, arranges screwed pipe or threaded rod at the two ends of round bar or pipe.The object of round bar or pipe that intermediate connector 1 is arranged to smooth outer surface avoids forming penetrating passage between structural concrete and round bar or pipe, and between existing stay bolt bar and structural concrete, form the gap of spiral, the gap of this spiral is that infiltration provides passage, therefore, the utility model adopts the round bar of smooth outer surface or pipe to stop this phenomenon, and arranges sealing piece 101 and prevent infiltration further.
As shown in Figure 1, Figure 2 and Figure 4, in the present embodiment, moment of torsion applying unit 204 is the radial moment of torsion application well being opened in fastening screw 203 end, it can be the structure such as circular hole, square hole, when applying moment of torsion, shaft-like instrument is used to insert in moment of torsion application well, rotational fastener screw rod 203.Certainly, moment of torsion applying unit 204 can also be the polygonal spiral shell head be arranged on fastening screw 203 free end, is coordinated with polygonal spiral shell head by Polygonal wrench, and rotary spanner reaches the object applying moment of torsion.
In this manual, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
