Description
Technical Field
The utility model relates to building construction, in particular to a steel plate waterstop positioning device for a tunnel.
Background
During the construction of the tunnel engineering, because the full-ring one-time pouring can not be realized, a longitudinal construction joint is often arranged according to the construction requirement, the longitudinal construction joint is generally reserved on the side wall of the longitudinal construction joint, and the construction joint is a channel which is often easy to become water leakage. In order to effectively prevent the water leakage of the construction joint, a design unit adds a steel plate water stop belt at the longitudinal construction joint to cut off the path of the water leakage. The steel plate water stop is processed into unit segments (generally 3m in length) with fixed unit length by a factory according to actual needs on site, and the unit segments are welded on site. Traditional steel sheet waterstop welding position needs two supplementary workman cooperation welders to carry out the leveling location, and artifical assistance-localization real-time easily appears the off normal, and steel sheet waterstop welding seam easily appears "V" style of calligraphy faying face and is difficult to weld, takes a lot of work and time moreover. Chinese utility model patent with the publication number of CN213539075U discloses a steel plate waterstop positioning device, which can not be used on side wall templates. The patent of the utility model discloses a steel plate waterstop fixing device, this utility model can only be used for steel reinforcement cage for chinese utility model patent with the publication number of authorizing CN 208815582U.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems and provides a positioning device for a steel plate waterstop for a tunnel, which supports the steel plate waterstop by being connected with a side wall template.
The utility model solves the technical problem, and adopts the technical scheme that:
a steel plate waterstop positioning device for a tunnel comprises a positioning piece for supporting a steel plate waterstop and a clamping piece for clamping and fixing on a side wall template, wherein the clamping piece is horizontal J-shaped, a hook part of the clamping piece faces downwards, and an anti-tilting plate vertical to the clamping piece is fixedly connected in the hook part; the positioning piece is in a B shape, and the horizontal part of the positioning piece is detachably connected with the horizontal part of the clamping piece. Compared with the prior art, the utility model adopting the technical scheme has the beneficial effects that:
simple structure, with low costs, easy, the convenient to use of drawing materials, location convenience improves the welding efficiency of steel sheet waterstop, improves construction quality, and reuse rate is high.
Further, the optimization scheme of the utility model is as follows:
the two ends of the bottom surface of the anti-roll plate are provided with disk-shaped positioning magnets.

Detailed Description
The utility model is further described in detail below with reference to the figures and examples.
Referring to fig. 1 to 4, the present embodiment is a steel plate waterstop positioning device for a tunnel, and the steel plate waterstop positioning device for a tunnel is composed of a clamping member 1, a positioning member 2, an anti-roll plate 3 and a bolt 4, wherein the clamping member 1 and the positioning member 2 are made of steel plates with a thickness of 3 mm.
The clamping piece 1 is in a horizontal J shape, a first hook part 1-1 of the clamping piece faces downwards, the first hook part 1-1 is used for hooking a side wall template 5, an anti-tilt plate 3 is welded on a lower horizontal plane in the first hook part 1-1, the anti-tilt plate 3 is in a strip shape and is perpendicular to the plate surface of the clamping piece 1, and disc-shaped positioning magnets are respectively installed at two ends of the bottom surface of the anti-tilt plate 3. The positioning piece 2 is in a shape of a Chinese character 'yi', a second hook part 2-1 of the positioning piece is used for supporting a steel plate water stop belt 6, the shape of the second hook part 2-1 is matched with that of the steel plate water stop belt 6, and a second horizontal part 2-2 of the positioning piece 2 is connected with a first horizontal part 1-2 of the clamping piece 1 through a bolt 4.
The construction process of the embodiment is as follows:
4 sets of once processing during the use of this embodiment, at first with the first hook portion 1-1 card of card firmware 1 solid to the department of the eave on side wall template 5, anti-tilt board 3 is located the lower plate of side wall template 5, location magnet adsorbs with side wall template 5, make the location more firm, the card position of fixing is according to the length (apart from both ends 1/4 department) card of steel sheet waterstop 6 and is fixed in the department of the eave on side wall template 5, installation setting element 2, setting element 2 encorbelments at vertical construction joint department, card firmware 1 is connected through bolt 4 with setting element 2. The lower end of the steel plate water stop belt 6 is arranged in the second hook part 2-2, the middle lower part of the steel plate water stop belt 6 is tightly attached to the vertical surface of the positioning part 2, after the two steel plate water stop belts 6 are adjusted to the designed welding length, a welder fixes the welding position of the steel plate water stop belt 6 with one hand, and meanwhile welding operation is carried out. After the steel plate water stop belt 6 is welded, the positioning device is not removed temporarily, and the positioning steel bars and the lining steel bars are welded (if the lining is plain concrete, the short steel bar heads and the template are welded and fixed temporarily). And after the positioning steel bar is welded, the bolt 4, the clamping piece 1 and the positioning piece 2 are removed.
The utility model replaces the function of assisting a welder to position the water stop by clamping the upper brim of the side wall template, the welder can operate by one person, the practicability is strong, the positioning accuracy is ensured, the operation difficulty is reduced, and the construction efficiency is improved; has the advantages of low processing cost, simple structure, easy material taking, convenient assembly and disassembly, and high repeated utilization rate of the device.
