Abstract
The invention discloses a kind of tunnel waterstop positioning fixture, it is characterized in that: passing through bolt on tunnel overhead arch mould plate is a vertically-mounted ambulatory splint, the horizonal base plate of movable intermediate plate arranges elongated bolt hole, ambulatory splint can horizontally slip along the plane of inverted arch template, and has the interior plate of the " u "-shaped card of the inner side being in ambulatory splint to form clamping plate with ambulatory splint；The upper semisection of waterstop is clamped in clamping plate；" u "-shaped card tips upside down on clamping plate with its card mouth down；The outer panel running through " u "-shaped card is provided with standing screw, and the rod end of standing screw is butted on the outside of ambulatory splint；Regulation standing screw, so that ambulatory splint moves to the interior plate of " u "-shaped card in " u "-shaped card, forms the clamping to waterstop.The present invention makes waterstop installation site correct, straight, indeformable, thus ensure that the waterproof effect in tunnel.
Description
Technical field
The present invention relates to the auxiliary implement in tunnel water proofing construction, more specifically one is applied when tunnel water proofing is constructed, will
What waterstop was fixed in concrete fixes and positions utensil.
Background technology
In constructing tunnel quality, tunnel water handling is emphasis and the difficult point of construction quality, and tunnel waterstop install be tunnel prevent
An important step in drainage system.For the installation of tunnel waterstop, the most conventional way is to weld in waterstop both sides
Reinforcing bar fixing to top, but at casting concrete and during making firm by ramming, may cause waterstop serpentine-like, the most between two parties, the most straight,
Even bury underground outside inverted arch and two lining concrete, do not have as the waterproof effect of construction joint, once there are infiltration or leaking existing
As, durability and usability to tunnel can have a huge impact.
Summary of the invention
The present invention is for avoiding the weak point existing for above-mentioned prior art, it is provided that a kind of tunnel waterstop positioning fixture, to protect
Card waterstop installation site is correct, straight, indeformable, it is ensured that the waterproof effect in tunnel.
The present invention solves technical problem and adopts the following technical scheme that
Being structurally characterized in that of tunnel waterstop positioning fixture of the present invention: passing through bolt on tunnel overhead arch mould plate is a vertically-mounted work
Dynamic clamping plate, arrange elongated bolt hole on the horizonal base plate of described movable intermediate plate, and ambulatory splint can be left along the plane of inverted arch template
Right slip, and have the interior plate of the " u "-shaped card of the inner side being in ambulatory splint to form clamping plate with described ambulatory splint；Waterstop
Upper semisection is clamped in described clamping plate；" u "-shaped card tips upside down on described clamping plate with its card mouth down；Run through described " u "-shaped card
Outer panel is provided with standing screw, and the rod end of described standing screw is butted on the outside of ambulatory splint；Regulate described standing screw so that
Obtain ambulatory splint to move to the interior plate of " u "-shaped card in " u "-shaped card, form the clamping to waterstop.
Compared with the prior art, the present invention has the beneficial effect that:
1, the present invention can make waterstop be accurately positioned, it is ensured that waterstop is buried underground placed in the middle, straight, reaches waterproof effect.
2, the present invention uses the form of fixture, it is not necessary to extra soldered reinforcing bar fixing to top, has saved amount of reinforcement.
3, present configuration is simple, it is easy to implements and repeatable recycles.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Label in figure: 1 ambulatory splint, 2 is " u "-shaped card, 2A outer panel, 2B interior plate, 3 nuts, 4 standing screws, 5
Waterstop, 6 inverted arch templates, 7 bolts, 8 elongated bolts hole.
Detailed description of the invention
Seeing Fig. 1, in the present embodiment, tunnel waterstop positioning fixture is to be pacified in vertical by bolt 7 on tunnel overhead arch mould plate 6
Filling an ambulatory splint 1, arrange elongated bolt hole 8 on the horizonal base plate of ambulatory splint 1, ambulatory splint 1 can be along inverted arch template
The plane of 6 horizontally slips, and has interior plate 2B and ambulatory splint 1 shape of the " u "-shaped card 2 of the inner side being in ambulatory splint 1
Become clamping plate；The upper semisection of waterstop 5 is clamped in clamping plate；" u "-shaped card 2 tips upside down on clamping plate with its card mouth down；Run through " U "
The outer panel 2A of shape card 2 is provided with standing screw 4, and the rod end of standing screw 4 is butted on the outside of ambulatory splint 1；Utilize nut
3 regulation standing screws 4, so that ambulatory splint 1 moves to the interior plate 2B of " u "-shaped card 2 in " u "-shaped card 2, are formed
Clamping to waterstop 5, ambulatory splint 1 is to make with angle steel.
In construction, when inverted arch concreting is close to time below waterstop, installation activity clamping plate on tunnel overhead arch mould plate, and with
The interior plate that ambulatory splint and " U " block clamps the upper semisection of waterstop jointly；Utilizing standing screw to carry out fastening to install, it is right to complete
The location of waterstop.
