Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a device for attaching a water stop plate to a flexible connection between underwater structures such as buried boxes and subterranean structures such as box culverts, gutters, and tunnels, which constitute a buried tunnel. About.

[0002]

2. Description of the Related Art A submerged tunnel is formed by sequentially connecting a plurality of submerged boxes.
As shown in FIG. 1, water is stopped by a rubber gasket 2 provided between the end surfaces 1a of the immersion box 1 and a water stop plate 3 attached between inner peripheral walls 1b of the immersion box 1. Further, in the case of a flexible joint of an underground structure such as a box culvert, a gutter, a canal, etc., the water blocking plate 3 is attached and water is stopped as described above.

[0003]

As shown in FIG. 1, such an installation device for a water-stop plate is provided with a nut 5 screwed to a bolt 4 provided in a submerged box 1 so that an edge of the water-stop plate 3 is fixed. Since the bolts 4 and nuts 5 are attached to the buried case 1 by being pressed, the tightening force is weakened due to corrosion and electrolytic corrosion of the bolts 4 and nuts 5 and leakage occurs.
However, leakage also occurs due to breakage.

Therefore, an object of the present invention is to provide a water blocking plate mounting device which can solve the above-mentioned problems.

SUMMARY OF THE INVENTION A water-stop plate 14 having a plate-like shape having a predetermined width and thickness and having mounting portions 15 having substantially circular cross sections at both ends in the width direction, a mounting base 24 provided with an anchor 23, and a support. A first mounting bracket 20 having a substantially C-shaped support concave portion 26 by a portion 25, and a second mounting bracket 21 having an anchor 23 and having an arc-shaped support surface 27 facing the support concave portion 26.
And a mounting recess 15 at the both ends in the width direction of the water stop plate 14 is elastically compressed by a supporting recess 26 of the first mounting bracket 20 and a supporting surface 27 of the second mounting bracket 21. It is deformed and clamped, and each of the mounting brackets 12 is cast in place on the opposing underground structure 10.
3. An installation device for a water stop plate, which is installed by fixing the anchor 23 in 3.

[0006]

The mounting portion 15 of the water stop plate 14 is attached to the first
The supporting recess 26 of the mounting bracket 20 and the support surface 27 of the second mounting bracket 21 of the mounting bracket 12 are elastically compression-deformed and clamped, and the mounting bracket 12 is fixed to the underground structure 10 by the cast-in-place concrete 13. Therefore, even when used for a long period of time, the water stop plate 14 can be securely attached for a long period without loosening of the holding portion 15 of the water stop plate 14, and no leakage occurs.

[0007]

[Embodiment] As shown in FIG. 2, a hook-shaped recess 11 is formed at an opposite end of an underground structure 10 such as a submerged box.
A mounting bracket 12 is mounted in the hook-shaped recess 11 with cast-in-place concrete 13, and the opposing mounting bracket 12,
12, both ends of the water stop plate 14 in the width direction are supported.
4 is attached across the underground structures 10, 10 facing each other. The mounting bracket 12 connects a first mounting bracket 20 and a second mounting bracket 21 by a hinge 22 so as to be rotatable.
Anchors 23 are respectively attached to the mounting brackets 20 and 21 by welding or the like, and the water blocking plate 14 is a long plate having a predetermined width and thickness made of a rubber material or the like. Has a substantially circular mounting portion 15 whose cross-sectional shape is larger in thickness than the thickness. The first mounting member 20 has a cross-sectional shape having a mounting base 24 provided with an anchor 23 and a substantially C-shaped support recess 26 formed by a substantially C-shaped support portion 25 continuous with the mounting base 24. The mounting bracket 21 is a support recess 2 of the first mounting bracket 20.
6, a hinge 22 is attached to the lower surface of the mounting base 24 of the first mounting member 20 and the lower surface of the second mounting member 21. Support recess 26 of mounting bracket 20 and second mounting bracket 2
The mounting portion 15 of the water stop plate 14 is sandwiched between the first support surfaces 27.

Next, the operation of attaching the water stop plate 14 will be described.
After the underground structure 10 is installed facing the mounting plate 20, the mounting brackets 20 are respectively mounted on the mounting portions 15 at both ends in the width direction of the water stop plate 14, and the mounting portions 15 are connected to the support recess 26 of the first mounting bracket 20 and the second mounting bracket. The support metal 21 is elastically compressed and deformed by the support surface 27 and firmly clamped. The mounting bracket 20 is temporarily placed in the hook-shaped recess 11 of the underground structure 10 by a support (not shown), and concrete is cast in this state and mounted. The metal fitting 20 is attached to the underground structure 10. Note that the support recess 26 of the first mounting member 20 and the second
The hinge 2 is used to elastically compress and deform the mounting portion 15 of the water blocking plate 14 and hold the mounting portion 15 on the support surface 27 of the mounting fitting 21 in a sandwiched state.
2 may be rotationally urged by a spring, or the second mounting member 21 may be urged and held by a spring in a pressing direction, and furthermore, the second mounting member 21 is pressed and temporarily connected by welding or the like. You may.

Next, a second embodiment will be described. The mounting base 24 of the first mounting bracket 20 and the opposite end of the second mounting bracket 21 are formed with concavities and convexities facing each other, and the concavities and convexities 28 are fitted together, and the shaft 29 is inserted through to form the first mounting bracket 20 and The second mounting member 21 is rotatably connected.

[Effect of the Invention] The mounting portion 15 of the water stop plate 14 is attached to the mounting bracket 12.
Of the first mounting bracket 20 and the supporting surface 27 of the second mounting bracket 21 of the mounting bracket 12 are elastically deformed and clamped, and the mounting bracket 12 is anchored to the underground structure 10 by cast-in-place concrete 13. Is fixed by fixing the water stop plate 1 even when used for a long time regardless of corrosion or galvanic corrosion.
The water stop plate 14 can be securely attached for a long period of time without loosening of the holding portion 15 of 4 and leakage does not occur.
