As described above, since the conventional water leakage prevention technique has a structure in which the water leakage prevention layer is provided between the outer layer and the inner layer of the concrete wall, the member constituting the water leakage prevention layer is made of concrete. After enclosing with a formwork, the process of pouring concrete must be performed. For this reason, it is necessary to install and remove the concrete formwork. Further, the water leakage prevention layer and the inner layer are separate members and cannot be handled integrally. Therefore, the construction work becomes complicated and troublesome.

Therefore, an object of the present invention is to provide a water leakage prevention wall member which is excellent in workability.

[0005]

In order to solve the above problems, the present invention is a wall member having an inner wall layer and a water leakage prevention layer, wherein the inner wall layer has a plate-like portion, The water leakage prevention layer has at least two face plates and a water passage, and the first face plate is water impermeable and is attached to one surface side of the plate-shaped portion of the inner wall layer. Are permeable to water, and are arranged on the front surface of the first face plate at intervals.
The water passage is formed in the space, is continuous in the vertical direction, and is open at both ends in the vertical direction.

[0006]

The inner wall layer has a plate-shaped portion, and in the water leakage prevention layer, the first face plate is attached to one surface side of the plate-shaped portion of the inner wall layer, and the second face plate is integrated with the first face plate. Has been done,
A water leakage preventing member in which an inner wall layer forming an inner wall of a room and a water leakage preventing layer are integrated is obtained. This water leakage prevention wall member can be used as a concrete formwork. Therefore, a dedicated concrete formwork is unnecessary. Moreover, the completed building can be attached later.

The second face plate is permeable to water and is arranged on the front face of the first face plate with a space therebetween. The water passage is formed within the space, is continuous in the vertical direction, and is open at both ends. Water leakage from a wall surface of a basement or an underground parking lot is guided into the water passage from the water-permeable second face plate, flows down the water passage in the vertical direction, and is discharged. Since the first face plate has water impermeability, water leaks introduced into the water passage will not leak to the inner wall side. Therefore, a wall member for preventing water leakage having a high ability of preventing water leakage can be obtained.

As described above, the inner wall layer 1 has the plate-shaped portion 11, and the water leakage prevention layer 2 has the first face plate 21 as the inner wall layer 1.
Attached to one surface side of the plate-like portion 11 of the second face plate 22.
Since it is integrated with the first face plate 21, a water leakage prevention member in which the inner wall layer forming the inner wall of the room and the water leakage prevention layer are integrated can be obtained. This water leakage prevention wall member can be used as a concrete formwork. Therefore, a dedicated concrete formwork is unnecessary. For example, as shown in FIG. 4, in a basement room or an underground parking lot, etc., the leakage preventing wall members 4 according to the present invention are sequentially arranged, and the concrete to be the wall surface 3 of the building is placed, whereby leakage of water occurs. Preventive walls can be constructed. The wall member 4 forming the water leakage prevention wall is left as it is. For this reason, a dedicated concrete formwork becomes unnecessary, and the work of installing and removing the concrete formwork can be omitted and the workability can be improved. In FIG. 4, 5 is a mounting bolt and 6 is an anchor bolt.

The second face plate 22 is permeable to water, and is arranged on the front face of the first face plate 21 with a gap g therebetween.

Therefore, as shown in FIG. 5, the water leakage from the wall surface 3 of the basement or the underground parking lot has the second permeability. It is guided from the face plate 22 into the water passage 23 as shown by an arrow a.
Then, it flows down the water passage 23 in the vertical direction, passes through the hole 71, and is discharged to the water tank 8. Since the first face plate 21 has water impermeability, the leaked water introduced into the water passage 23 does not leak to the indoor side. In FIG. 5, 9 is a spring water treatment layer arranged on the foundation floor surface, 10 is a floor member, and 71 is a spring discharge hole. In FIGS. 1 and 2, the water passage 23 is partitioned into a plurality of partitions by a partition member 24 arranged between the first face plate 21 and the second face plate 22 within the gap g. Each of the partition members 24 has a distance d in the width direction and a distance g
Is arranged between the first face plate 21 and the second face plate 22 so as to traverse. The partition member 24 is formed integrally with the first face plate 21 and the second partition plate 22.
