Abstract
The utility model provides a steel-edged water-stop fixing device, which comprises a clamping-piece device, a fastening device and a vertical end-part supporting bracket, wherein the fastening device is used for tightly clamping the clamping-piece device, and the vertical end-part supporting bracket is used for supporting the clamping-piece device; and the clamping-piece device comprises two hollow square steels and an angle-steel pair, wherein the angle-steel pair is welded at intervals on the upper surfaces of the hollow square steels. In practice, the longitudinal straightness and the accurate buried depth of a steel-edged water stop can be ensured by adopting the steel-edged water-stop fixing device disclosed by the utility model, so that a swelling strip of the steel-edged water stop is accurately pre-buried, and meanwhile, the closely-overlapping requirements of a front water stop and a rear water stop can also be met to perform a good waterproof effect.
Description
Technical field
The utility model belongs to the waterstop construction field, relates in particular to a kind of fastening devices of waterstop.
Background technology
The constuction joint place adopts pre-buried steel limit waterstop to carry out waterproof usually between tunnel invert and two linings; Steel limit waterstop carries out pre-buried when the inverted arch concrete construction; Code requirement is pre-buried during construction must be straight; Length of embedment will guarantee that the middle part rubber strip is in the constuction joint middle part, can play the sealing effect, so the construction of steel limit waterstop is the key of constuction joint place waterproof between tunnel invert and two linings.
Traditional steel limit waterstop job practices is directly after the inverted arch fill concrete is built, and manual work is drawn out a groove and imbedded steel limit waterstop before concrete initial set; Though the method is simple and convenient, the steel limit waterstop horizontal direction utmost point of imbedding is not straight, vertically deep mixed yet; Before and after the waterstop of overlap joint can not be closely connected, dislocation often appears, and in construction often by breakage; Waterproof effect is very poor, does not reach standard and owner's requirement.
The utility model content
The technical problem that the utility model will solve is the deficiency that overcomes prior art, proposes the fastening devices of a kind of simple in structure, easy construction, steel limit waterstop that cost is low.
For realizing the fixing purpose of steel limit waterstop; The utility model proposes a kind of steel limit waterstop fastening devices, and said steel limit waterstop fastening devices comprises clip device, be used for clamping the fastener of said clip device and be used to support the vertical end supporting bracket of said clip device; Said clip device by two hollow square steels and the angle steel that at interval is welded on said hollow square steel upper surface to forming.
In the above-mentioned steel limit waterstop fastening devices, the right spacing distance of said angle steel is preferably 2m～3m.
In the above-mentioned steel limit waterstop fastening devices, the right single angle steel length of said angle steel is preferably more than the 5cm.
In the above-mentioned steel limit waterstop fastening devices, an acting surface of the single angle steel that said angle steel is right and the upper surface of said hollow square steel are fitted, and another acting surface is positioned on the plane of flattening of said hollow square steel medial surface.
Compared with prior art; The advantage of the utility model is: steel limit waterstop fastening devices has guaranteed that steel limit waterstop is vertically straight, and buried depth is accurate, makes steel limit waterstop expansion bar pre-buried accurately; Two waterstop overlap joints are closely connected before and after satisfying simultaneously, play good waterproof effect.

The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is further described.
Embodiment
A kind of steel limit waterstop fastening devices as shown in Figure 1, steel limit waterstop fastening devices comprise clip device, be used for clamping the set bolt 3 of clip device and be used to support the vertical end supporting bracket 4 of clip device; Clip device by two hollow square steels 1 and at the angle steel of hollow square steel 1 upper surface welding to forming, angle steel is to comprising two angle steel 2 that are symmetric arrangement, angle steel is 2m～3m to the spacing of the waterstop bearing of trend along the steel limit.Wherein, the length of the single angle steel 2 of angle steel centering is more than the 5cm.The acting surface of the single angle steel 2 of angle steel centering and the upper surface of hollow square steel 1 are fitted, and another acting surface is positioned on the plane of flattening of hollow square steel 1 medial surface.
The method for using of the steel limit waterstop fastening devices of present embodiment is as shown in Figure 2: at first; Place two hollow square steels 1 middle the first half of steel limit waterstop 5; It is right to utilize set bolt 3 to clamp angle steel then; And then making two hollow square steels 1 clamp the first half of steel limit waterstop 5, the latter half of steel limit waterstop 5 is then directly imbedded in the concrete when inverted arch concreting, and guarantees that the rubber swelling bar at waterstop 5 middle parts, steel limit is positioned at the constuction joint middle part just.
Claims (5)
1. steel limit waterstop fastening devices is characterized in that: said steel limit waterstop fastening devices comprises clip device, be used for clamping the fastener of said clip device and be used to support the vertical end supporting bracket of said clip device; Said clip device by two hollow square steels and the angle steel that at interval is welded on said hollow square steel upper surface to forming.
2. steel according to claim 1 limit waterstop fastening devices is characterized in that: the right spacing distance of said angle steel is 2m～3m.
