Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for attaching a water stop plate to a flexible joint between submerged structures such as a submerged box forming a submerged tunnel or underground structures such as a box culvert, a gutter, and a cavern.

[0002]

[Prior art]

 The submerged tunnel is formed by sequentially connecting a plurality of submerged boxes, and the flexible joint between the submerged boxes is, for example, as shown in FIG. 1, a rubber gasket 2 and a submerged box provided between the end faces 1a of the submerged box 1. The water is stopped by the water stop plate 3 attached between the inner peripheral walls 1b of the first embodiment. In addition, in the soft joints of underground structures such as box culverts, gutters, and caverns, the water stop plate 3 is attached to stop water in the same manner as described above.

[0003]

[Problems to be solved by the device]

 As shown in FIG. 1, such a water blocking plate mounting device is mounted by screwing a nut 5 onto a bolt 4 embedded in the submersible box 1 and pressing the edge of the water blocking plate 3 against the submerged box 1. The bolts 4 and nuts 5 are corroded and electrolytically corroded due to long-term use, and the tightening force is weakened, causing leakage, and even if the bolts 4 are broken due to the high stress acting on the bolts 4, leakage may occur. Occur.

Therefore, an object of the present invention is to provide a water stop plate mounting device capable of solving the above-mentioned problems.

[0005]

A mounting bracket 13 is provided, and a mounting board 11 is embedded in the underground structure 10 and has a groove 12 on the surface 11a. The mounting base 20 of the mounting bracket 13 is fitted into the groove 12 of the mounting board 11, The mounting portions 15 at both ends in the width direction of the water blocking plate 14 are elastically compressed and deformed between the supporting recessed portion 22 of the mounting bracket 13 and the surface 11a of the mounting substrate 11, and the mounting brackets 13 are mounted on the mounting substrate 11. A water stop plate mounting device that is welded and fixed.

[0006]

[Work]

 Since the mounting portion 15 of the water blocking plate 14 is elastically compressed and deformed between the support concave portion 22 of the mounting bracket 13 and the surface 11a of the mounting substrate 11 and the mounting bracket 13 is welded and fixed to the mounting bracket 11, Even if the water blocking plate 14 is used for a period of time, the holding portion 15 of the water blocking plate 14 does not loosen, and the water blocking plate 14 can be reliably mounted for a long period of time without leakage.

[0007]

【Example】

 As shown in FIG. 2, a mounting substrate 11 is embedded at the opposite end of the underground trench structure 10 such as a submerged box when the underground structure 10 is manufactured. The surface 11a of the mounting board 11 is flush with the surface 10a of the underground structure 10 to serve as a water stop plate mounting surface, and the mounting metal fitting 13 is fitted into the groove 12 formed in the mounting board 11 and fixed by welding. Both end portions in the width direction of the water blocking plate 14 are supported by the mounting fittings 13, 13 facing each other, and the water blocking plate 14 is mounted across the opposing underground structures 10, 10. The water blocking plate 14 is made of a rubber material or the like and has an elongated plate shape having a predetermined width and thickness, and a substantially circular mounting portion 15 having a cross-sectional shape larger than the thickness is provided at both ends in the width direction. It has it integrally in the direction. The mounting bracket 13 has a cross-sectional shape having a substantially C-shaped support recess 22 formed by a mounting base 20 that fits into the groove 12 of the mounting substrate 11 and a substantially C-shaped support 21 that is continuous with the mounting base 20. The mounting recess 15 of the mounting bracket 13 and the surface 11a of the mounting substrate 11 hold the mounting portion 15 of the water blocking plate 14.

Next, the work of attaching the water stop plate 14 will be described. After the underground structures 10 are installed to face each other, the mounting portions 15 at both ends in the width direction of the water blocking plate 14 are placed on the surface 11a of the mounting substrate 11, and the mounting portions 20 of the mounting bracket 13 are mounted on the groove portions of the mounting substrate 11. 12 is fitted to the support recess 13 of the mounting bracket 13 and the surface 11a of the mounting substrate 11 to be elastically compressed and firmly sandwiched, and the mounting bracket 13 is welded to the mounting substrate 11 for individual mounting. In addition, the reinforcing station 23 may be welded across the support portion 21 of the mounting member 13 and the surface 11 a of the mounting substrate 11.

FIG. 3 shows a second embodiment, in which the groove 12 of the mounting board 11 is wide and one end 12a in the width direction is substantially V-shaped, and the mounting base 20 of the mounting bracket 13 is wide and one end 20a in the width direction. Is formed into a wedge shape, and one end portion 20a in the width direction of the wedge shape is tightly fitted to one end portion 12a in the groove 12 having a substantially V shape in the width direction, and the other end portion 20b in the width direction of the mounting base portion 20 and the mounting substrate 11 are welded. It is stuck. By doing so, it is possible to reduce that the welding portion A between the mounting substrate 20 and the mounting substrate 11 is separated from the water blocking plate 14 by a long distance, and the heat during welding is transferred to the water blocking plate 14. In FIG. 3, a reinforcing cloth 16 is provided on the mounting portion 15 of the water stop plate 14.

[0010]

[Effect of device]

 Since the mounting portion 15 of the water blocking plate 14 is elastically compressed and deformed between the support recess 22 of the mounting bracket 13 and the surface 11a of the mounting substrate 11, and the mounting bracket 13 is welded and fixed to the mounting substrate 11, Even if the water blocking plate 14 is used for a period of time, the holding portion 15 of the water blocking plate 14 does not loosen, and the water blocking plate 14 can be reliably mounted for a long period of time without leakage. In addition, since the mounting bracket 13 may be welded and fixed to the mounting substrate 11 at the installation site of the underground structure, its turning property is excellent.
