Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
A fixing member 10 for a flexible water-stopping member of the present invention is used in place of, for example, the conventional fixing member 5 shown in FIG. 9, and includes a concrete structure 1 on an existing side and a concrete side on a new side. It is used for fixing instead of the fixing member 5 to the structure 1 on the existing side of the flexible waterproofing member 4 constructed between the joint part 3 and the structure 2. That is, the conventional fixing member 5 has a bolt hole of the anchoring portion 4b of the flexible water-stopping member 4 provided with the expansion / contraction portion 4a in the anchor bolt 6 attached to the structure 1, and the nut 8 through the presser plate 7 It was fixed by tightening.
On the other hand, the fixing member 10 of the present application is used for fixing the flexible water blocking member 20.
For example, as shown in FIG. 1, the flexible waterproofing member 20 to be fixed includes an extension / contraction part 21 (see reference numeral 4 a in FIG. 9) that allows displacement, and an extension part 21 that extends to the end edge part 22. A fixing ridge portion 23 provided for fixing is provided. The fixing member 10 for the flexible waterproofing member 20 that fixes the flexible waterproofing member 20 to the structure 1 is inserted into the anchor bolt 6 attached to the structure 1 through a long hole 11a (see FIG. 2A). Fastening portion 11 to be tightened, groove portion 12 extending to one end of fastening portion 11 to cover convex ridge portion 23 of flexible water-stopping member 20 and suppressing rotation, and extending to the other end of fastening portion 11 1 is provided with an edge support part 13 that is applied to the surface 1a of the first part and forms a space D between the fastening part 11 and the structure 1.
As a result, the fixing member 10 covers the groove portion 12 at one end of the fastening portion 11 on the protruding strip portion 23 of the flexible water-stopping member 20, and the edge support portion 13 at the other end of the fastening portion 11 is attached to the structure 1. The intermediate fastening portion 11 is fixed to the anchor bolt 6 by bending and tightening the anchor bolt 6 so as to narrow the space D.
In this case, the flexible waterproofing member 20 is fixed to the newly-constructed concrete structure 2 without using the fixing member 10 as shown in FIG. It fixes through 2a etc., and it fixes by embed | buying in the concrete to lay.
Although the illustration of the fixing member 10 is omitted, it is also applicable to the case where the flexible water blocking member 20 is attached so as to straddle the joint portion 3 along the inside of the joint portion 3 of the concrete structures 1 and 2 after construction. In this case, the fixing member 10 is used for fixing via the protruding ridges 23 at both ends of the flexible waterproof joint 20.

  The flexible waterproofing member 20 to be fixed by the fixing member 10 is provided at an end portion 22 that extends to the expansion / contraction portion 21 (see reference numeral 4a in FIG. 9) that allows displacement, and the expansion / contraction portion 21. The fixing ridge 23 is provided on the side fixed by the fixing member 10, and is provided on at least one of the end rims 22. It only has to be provided.

  The flexible waterproofing member 20 is made of an elastic member such as rubber or synthetic resin. For example, as shown in FIG. 8, a reinforcing cloth 25 is used as a reinforcing cloth 25 depending on a required strength. Is done. In addition, the flexible water blocking member 20 may be installed and used so as to cover the outside when the flexible water blocking member 20 is constructed without forming the reinforcing cloth 25 as an inner layer.

The expansion / contraction part 21 which accept | permits a displacement is comprised as the expansion-contraction part 4a of a hollow body as shown, for example in FIG. 9, For example, the expansion / contraction part 21 of the normal flexible water-stop member 20 shown in FIG. The cross-sectional shape (not shown) is formed as an arc shape and is formed into one substantially Ω shape, or is configured to meander in a substantially W shape in which a plurality of arc shapes (not shown) are continuous. Things are used. The shape of the expansion / contraction part 21 is not limited as long as it can allow unequal settlement of the structures 1 and 2, displacement due to an earthquake, displacement due to temperature change, and the like.
The edge part 22 should just be a flat strip | belt shape etc. which can be installed in the surface 1a of the structure 1, and a shape etc. are not specifically limited like the expansion-contraction part 21. FIG.

For example, as shown in FIG. 1, the fixing ridge portion 23 is integrally formed so as to protrude outward (outside the surface 1 a of the structure 1) at the end edge portion 22. For example, the cross-sectional shape is rectangular. It is formed.
The shape of the ridge 23 is not limited to the case where the cross-sectional shape is rectangular, but is not shown in the figure. However, the trapezoidal shape or the top protrudes outward and the base is located on the edge 22 and is integrally formed. The shape may be a shape, and the shape is not limited at all, and any shape that can be pressed from the outside toward the surface 1 a of the structure 1 by a groove portion 12 of the fixing member 10 described later may be used.

The fixing member 10 of the present application for fixing such a flexible water-stopping member 20 is, for example, as shown in FIGS. 1 and 2 through an anchor bolt 6 attached to the structure 1 via a long hole 11a. Fastening portion 11 to be tightened, groove portion 12 extending to one end of fastening portion 11 to cover convex ridge portion 23 of flexible water-stopping member 20 and suppressing rotation, and structure 1 extending to the other end of fastening portion 11 And an edge support portion 13 that forms a space D between the fastening portion 11 and the structure 1 by being brought into contact with the surface 1a.
That is, the fixing member 10 is integrally formed of a metal plate, is pressed so as to cover the protruding strip portion 23 of the flexible water-stopping member 20 with the groove portion 12 at one end, and the edge support portion 13 at the other end is structured. The intermediate fastening portion 11 is bent so as to narrow the space D and is fastened with the anchor bolt 6 while being in contact with the front surface 1a.

The fastening portion 11 is a portion that is fastened and fixed to the anchor bolt 6 planted on the surface 1 a of the structure 1. A long hole 11 a is formed so as to cope with a change in the pitch of the anchor bolt 6. 3 corresponds to the change of the pitch in the longitudinal direction along 3. Further, unlike the conventional presser plate, the fastening portion 11 is not anchored between the surface 1a of the structure 1 and the anchor bolt 6 with only the fastening portion 11 without sandwiching the end edge portion 22 of the flexible water blocking member 20. The nut 8 is tightened. In this tightened state, a space D is formed between the fastening portion 11 and the surface 1 a of the structure 1.
If the elongated holes 11a are formed in a direction perpendicular to the pitch direction of the anchor bolts 6, it is possible to easily cope with the displacement of the anchor bolts 6 in this direction.

The groove portion 12 is integrally provided on one end of the fastening portion 11 and the joint portion 3 side. A groove 12 having a U-shaped cross section is formed by bending upward from one end of the fastening portion 11 and away from the surface 1a of the structure 1, and is open toward the surface 1a side of the structure 1.
The groove portion 12 of the fixing member 10 has groove side wall portions 12a on both sides formed at intervals between the convex strip portions 23 of the flexible water-stopping member 20, and the convex strip portions 23 attached to the groove portion 12 are on the outer side. It can be covered from.
Even if the fixing member 10 is tightened by covering the ridges 23 of the flexible water-stopping member 20 from three sides with such grooves 12, the grooves of the ridges 23 of the elastic member as shown in FIG. The side wall 12a can be prevented from bulging outward, and can act as a pressing force accompanying elastic deformation on the surface 1a side of the structure 1, as shown in FIG. Can do.

In addition, the fixing member 10 is anchored by the groove 12 and the ridge 23 attached to the groove 12 even when the width B in the direction along the joint 3 is fastened to one anchor bolt 6 as shown in FIG. A width B is secured so as not to rotate around the bolt 6. That is, since the groove portion 12 of the fixing member 10 has a width B and covers the convex portion 23 of the flexible water-stopping member 20, rotation around an axis perpendicular to the surface 1a of the structure 1 can be prevented. .
Note that the width B of the fixing member 10 may be one in which long holes 11 a for mounting to a plurality of anchor bolts 6 are formed for one fixing member 10, and the width 1 of the surface 1 a of the structure 1. What is necessary is just to set to the width | variety B which can ensure water-stopping and can be attached even if there is unevenness. Therefore, the width B of the fixing member 10 does not necessarily have to be constant, and those having different widths B may be used.
Further, as shown in FIG. 3, the fixing member 10 is sealed with a tape 14 that is a sealing member so as to close a gap between the adjacent fixing members 10. By doing so, it is possible to prevent the gaps between the joint portions 3 from being blocked by the tape 14 which is a sealing member, and dirt and the like from staying.

At the other end of the fastening portion 11, an edge support portion 13 is integrally provided so as to protrude obliquely downward. By applying the tip of the edge support portion 13 to the surface 1 a of the structure 1, the bottom surface of the protruding strip portion 23 of the flexible water blocking member 20 mounted in the groove portion 12 is positioned on the surface 1 a of the structure 1. In the fastening portion 11 attached to the anchor bolt 6 through the long hole 11a, a space D away from the surface 1a of the structure 1 is formed.
When the nut 8 is screwed into the anchor bolt 6 and tightened in a state where the flexible water blocking member 20 is pressed by such a fixing member 10, the fixing member 10 is tightened so as to bend about the end edge support portion 13, and the groove portion 12. The inner ridge 23 is pressed against the surface 1a of the structure 1 to be in a close contact state and stopped.
Thereby, the flexible water blocking member 20 can be fixed by applying the bending force of the fixing member 10 via the anchor bolt 6.

In such a fixing member 10, the mounting height of the fastening portion 11 to the anchor bolt 6 (distance from the surface 1 a of the structure 1) is low (the distance is small), and the water pressure applied to the flexible water blocking member 20 is As shown in FIG. 2B, the center of moment O is located on the lower surface of the nut 8 even if a force that peels off the edge 22 is applied, and the moment to be peeled off (the surface 1a of the structure 1 and The moment around a parallel axis) is smaller than before, and water stoppage can be improved.
Moreover, if the moment which peels off the edge part 22 of this flexible water-stop member 20 is made the same, the size of the anchor bolt 6 can be made small and the same water-stopping property can be ensured.
Further, since the position of the nut 8 to be fastened to the anchor bolt 6 is small in the distance from the surface 1a of the structure 1 (the center O of the moment is low), as shown in FIG. When the edge portion 22 of the member 20 is fixed in the joint portion 3, the interference between the structure 2 and the anchor bolt 6 can be prevented even if the joint portion 3 to which the structures 1 and 2 approach is contracted. it can.
In particular, as shown in FIG. 5 (a), when the stretchable portion 21 of the flexible water blocking member 20 is deformed so as to be crushed, in the conventional structure, the stretchable portion 21 contacts the thread of the anchor bolt 6. There is a risk of causing damage to the flexible water-stopping member 20, but when the fixing member 10 according to the present invention is used, interference can be prevented by the deformation space d to ensure a water-stopping state. .

In the fixing member 10, the edge support portion 13 has a low height from the surface 1 a of the structure 1, then the nut 8 of the anchor bolt 6 is high, and the groove portion 12 is the highest and is sequentially increased. The flow from the edge support portion 13 to the groove portion 12 becomes smooth, and for example, as shown by an arrow in FIG. 2B, turbulent flow such as vortex can be prevented.
Thereby, the fixing member 10 is attached in a state where the fluid flowing in the structure 1 is not blocked and has a rectifying effect.
This rectification effect becomes more effective particularly when both ends of the flexible water-stopping member 20 are fixed to the inner surface 1a of the structure 1 which becomes a water channel across the joint portion 3 of the structure 1, and the flow resistance is reduced. Can be reduced.

Next, the shape of the rectification unit 15 for increasing the rectification effect by the fixing member 10 will be described.
For example, the rectifying unit 15a illustrated in FIG. 6A includes a bent portion 13a obtained by bending the edge support portion 13 of the fastening portion 11 inward, and further, the surface of the structure 1 inside the edge support portion 13. It is formed by bending in an inverted U shape so as to protrude substantially vertically from 1a, and the height of the rectifying portion 15a is formed substantially the same as that of the groove portion 12.
The fixing member 10 is provided with such a rectifying portion 15a, so that the anchor bolt 6 and the nut 8 are hidden between the rectifying portion 15a and the groove portion 12, and the end surface of the edge support portion 13 is a flat surface. Instead of the curved surface, the flow can be smoothed by the rectifying unit 15a.
Further, for example, the rectifying unit 15b shown in FIG. 6B has a protruding height from the surface 1a of the structure 1 lower than that of the rectifying unit 15a, and the edge support unit 13 side is inclined. It is formed by bending.
Since the fixing member 10 includes such a rectifying portion 15b, the flow toward the anchor bolt 6 and the nut 8 can be further smoothed by the rectifying portion 15b configured by an inclined surface.

Further, for example, the rectifying unit 15c shown in FIG. 6C is configured by a bent portion 13a obtained by bending the edge support portion 13 inward, and an inclined surface continuous to the bent portion 13a is formed. . The rectifying unit 15c has a protruding height from the surface 1a of the structure 1 that is comparable to the rectifying unit 15a.
The fixing member 10 includes such a rectifying portion 15c, so that the end surface of the edge support portion 13 is not a flat surface but a curved surface, and the flow toward the anchor bolt 6 and the nut 8 is configured by one inclined surface. The current can be rectified by the rectifying unit 15c, and can be rectified more smoothly.

The fixing member 10 avoids a decrease in water stoppage due to water pressure applied to the flexible waterstop member 20 when the installation height on the surface 1a of the structure 1 is lowered, or an anchor bolt when the flexible waterstop member 20 is deformed. This is effective in avoiding interference with the thread 6.
Therefore, the anchor bolt 6 is implanted in the structure 1 through the resin capsule 6a as shown in FIG. 7 (a). Thereby, the upper end position of the anchor bolt 6 can be adjusted, and the protrusion amount from the nut 8 of the anchor bolt 6 can be minimized.
Furthermore, by using the resin capsule 6a instead of the anchor bolt 6 and the hexagon bolt 6b as the insert anchor, the protrusion of the screw from the anchor bolt 6 can be eliminated as compared with the case of the nut 8.
Thereby, the fixed height of the flexible water blocking member 20 by the fixing member 10 can be suppressed low.
