Description
Technical field
The present invention relates to tunnel inverted arch waterstop construction fields, and in particular to a kind of tunnel inverted arch buried water strip fixture.
Background technique
In constructing tunnel quality, tunnel water handling is the key points and difficulties of construction quality, and tunnel inverted arch waterstop is pacified
Dress is the important link in tunnel waterproof and water drainage system.Currently, inverted arch short abutment wall buried water strip fixture in tunnel is by reinforcing bar mostly
Equal profiles are welded to form, and the buried water strip fixture peace of this welding tears inconvenience open, not reproducible to be used in turn.
Summary of the invention
The purpose of the present invention is to provide a kind of tunnel inverted arch buried water strip fixtures, in the short abutment wall of tunnel inverted arch
Buried water strip is installed, cannot be used in turn with solving the problem of that buried water strip fixture peace tears inconvenience fixture open in the prior art.
To achieve the goals above, scheme provided by the invention is as follows:
A kind of tunnel inverted arch buried water strip fixture, including clamping piece and several connectors, the clamping piece include first
The waist of channel steel and the second channel steel, first channel steel and the second channel steel is close to each other, and the upper leg of the first channel steel is equipped with several edges
The upper leg of the uniformly distributed first through hole of first channel steel length direction, the second channel steel is equipped with several corresponding with the first through hole second
Through-hole is respectively arranged below locating rack, the locating rack lower part and two side plane of tunnel inverted arch in the first channel steel and the second channel steel
It is fixedly connected, the connector includes U-bolt, and the both ends of U-bolt are each passed through first through hole and the second through-hole, passes through the
One end of the U-bolt of one through-hole is removably connected with positioning mechanism, is welded with across one end of the U-bolt of the second through-hole
Two nuts are threaded with the second screw rod on second nut, wirerope are connected on U-bolt.
The principle of base case of the present invention is:
The second screw rod on second nut is unscrewed off the second nut, after one end of U-bolt is passed through first through hole
Positioning mechanism is put on, the second screw rod is screwed in into the second nut after the second through-hole by the other end of U-bolt, sealing is buried by
Band is put into the crack between the first channel steel and the second channel steel waist close to each other, adjusts the overhang of buried water strip
After height, the second screw rod of turn moves the second screw rod to the first channel steel direction, and the second screw rod is by the second channel steel to the first channel steel
Direction promotes in the crack to which buried water strip to be clamped between the first channel steel and the second channel steel waist close to each other, root
After connecting multiple U-bolts with clamping piece according to the length of inverted arch, the wirerope on U-bolt is hung over to the suspension hook of boom hoisting
On, clamping piece is lain in a horizontal plane on locating rack by boom hoisting, buried water strip lower end is made to keep vertical state.
The beneficial effect that this programme generates is:
One, this programme presss from both sides clamping piece to waterstop by turn screw rod in U-bolt one end welded nut
Tightly, facilitate the height dimension of adjustment waterstop overhang, while screw rod plays the role of lifting clamping piece.
Two, being detachably connected for U-bolt and channel steel keeps fixture reusable.
Three, locating rack is set below clamping piece, improves the levelness that clamping piece is placed, ensure that hanging down for waterstop installation
Straight degree.
Further, the optimization as basic scheme, first channel steel are identical as the specification of second channel steel.
The channel steel pairing use of two same sizes clamps buried water strip from two sides, buries only during when lifting is entire
The two sides weight of water band is identical, is not susceptible to deflect, and is conducive to buried water strip and keeps vertical state.
Further, the positioning mechanism is the first nut cooperated with U-bolt.Connect in the other end screw thread of U-bolt
Connected nut can adjust the effect of waterstop two sides channel steel height when lifting by crane clamping piece.
Further, the rounded hole of first through hole, the diameter of first through hole are greater than the diameter 2-5mm of U-bolt.Facilitate U-shaped
Bolt guarantees that the first nut will not be such that nut plays and undertake the first channel steel weight by first through hole by first through hole
Effect.
Further, the axis of thread of second nut is vertical with the second channel steel waist side.
Further, third screw rod is welded on U-bolt, two adjacent U-bolts are connected by connecting plate, the company
Fishplate bar both ends are respectively equipped with the third through-hole of the cooperation of the third screw rod with two on adjacent U-bolt.When will be adjacent with connecting plate
When two U-bolts are fixedly connected, the U-bolt when lifting to fixture is made not effectively prevent U to lifting center position deflection
The bending deformation of type bolt.
Further, the third through-hole is in long hole, and the length direction of the long hole is consistent with the second channel steel length direction.
