DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure and a cover member for a wall portion located underground, and more particularly to a waterproof structure for a wall portion which comes into contact with soil, such as a foundation of a building or an outer wall of a basement. The present invention relates to a suitable waterproof structure and cover member.

[0002]

2. Description of the Related Art When an underground space such as a basement or a semi-basement is constructed, a wall surface made of concrete is usually formed to surround the underground space. However, since the outer wall side of this wall comes into contact with the soil, the moisture in the soil easily permeates the concrete. For this reason, in the case of a basement, there is a problem that the water permeated into the concrete permeates into the underground space to increase the humidity, and that dew forms on a wall surface or the like, and mold tends to occur.

On the other hand, the outer wall side of the wall, that is,
It is considered to cover the surface that comes in contact with the soil. For example,
Cover the wall with a panel with many irregularities, and on it,
It is contemplated to cover with a permeable sheet. In this case, a space is formed between the concrete wall surface and the water permeable sheet by the panel having the unevenness, and water seeping from the water permeable sheet flows down along this space. Thereby, it is possible to prevent the water in the soil from seeping into the concrete wall surface. Further, it is expected that the water that affects the wall surface can be more completely eliminated by collecting the water that has flowed down and draining it naturally or forcibly.

[0004]

However, it is conceivable that earth and sand may flow into the laminated body of the uneven panel and the water-permeable sheet from the upper end thereof. Therefore, it is necessary to take measures such as bending the upper end and attaching tape. However, these treatments are troublesome in construction, and improvements are desired.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a waterproof structure and a cover member for an underground wall having a structure capable of easily processing an upper end portion.

[0006]

Means for Solving the Problems The present invention has been made to achieve the above-mentioned object, and a first aspect of the present invention is to provide a waterproof structure for a wall portion installed in the underground portion, which is connected in at least one direction. A spacer panel having a recess formed therein, a sheet for covering the spacer panel, a water-permeable sheet having water permeability, and a cover member for covering an upper end portion of the laminate of the spacer panel and the water-permeable sheet. The spacer panel is arranged on the surface of the wall portion in a state where the recess provided therein is communicated at least in the vertical direction, and the spacer panel is laminated in a state of being covered with a water-permeable sheet. There is provided a waterproof structure for an underground wall portion, wherein the cover member is fixed to a wall portion while covering an upper end portion of the laminate.

[0007] It further comprises a heat insulating panel having heat insulating properties,
The heat insulation panel may be disposed between the wall portion and the spacer panel.

In this case, the heat-insulating panel is disposed so as to cover also the upper side of the wall surface from the position covered by the spacer panel, and the cover member is fixed to the heat-insulating panel, and the spacer panel and the spacer panel are fixed. The structure which covers the upper end part of the laminated body of a water-permeable sheet may be sufficient.

An underground wall surface waterproof structure is provided, wherein an upper end of the laminated body of the spacer panel and the water-permeable sheet is located on the ground surface, and the upper end is covered by the cover member. Is done.

In this case, the cover member may have a ventilation hole at a portion covering the upper end of the laminate.

According to a second aspect of the present invention, a spacer panel having a concave portion communicating with at least one direction and a water-permeable sheet having water permeability are laminated in this order, and a wall surface installed in an underground portion is provided. A cover member for covering an upper end portion of the laminate covering the surface of the portion, a fixing portion fixed to the wall portion side, an intermediate portion covering an upper end portion of the laminate, And a holding part for holding the edge,
A cover member is provided in which the fixing portion, the intermediate portion, and the holding portion are integrally formed side by side in this order.

[0012] The intermediate portion may have a ventilation hole.

The operation will be described.

The spacer panel is arranged on the surface of the wall portion in a state where the recess provided therein is communicated at least in the vertical direction. Then, it is laminated in a state where it is covered with a water-permeable sheet. Furthermore, the cover member is fixed to the wall surface in a state of covering the upper ends of these laminates. And
The upper end is covered with a cover member. This can prevent inflow of earth and sand from the upper end.

If the upper end of the laminated body of the spacer panel and the water-permeable sheet is located on the ground surface, the inflow of earth and sand can be prevented more reliably. In this case, if a ventilation hole is provided in the cover member, moisture in the space between the spacer panel and the wall surface can be quickly discharged to the ground.

When a heat insulating panel is employed, it is disposed between the wall and the spacer panel. In this case, the heat insulating panel is arranged so as to cover the upper side than the position covered by the spacer panel on the wall surface. The cover member is fixed to the heat insulating panel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
This will be described with reference to the drawings.

First, an outline of a waterproofing method according to an embodiment of the present invention will be described with reference to FIG.

The basement, semi-basement, and the like are constructed with a wall surface w made of concrete as an outer shell. A portion of the wall surface portion w that is buried in the ground is provided with the separator 1 of the present invention outside the portion. As a result, the wall portion w is directly
To avoid contact with Further, the cover member 4 is disposed above the isolator 1 so that the wall w and the isolator 1
Rainwater or the like can be prevented from entering the gap from the upper end.

Next, the separator 1 and the cover member 4 of the present embodiment will be described in detail.

First, the separator 1 will be described with reference to FIGS.

The underground portion of the wall of the isolator 1 is directly
As shown in FIG. 2, a spacer panel 2 and a water-permeable sheet 3 wrapping the spacer panel 2 are provided to prevent the soil from touching the soil.
Consists of

The spacer panel 2 is, as shown in FIG.
It is a water-impermeable plate-like member, and convex portions 20 are provided at various places on the both surfaces thereof over the entire surface. A region between the convex portions 20 constitutes a concave space 21 communicating in at least one direction (see FIG. 2). At the time of construction, the spacer panel 2 is buried along the wall surface w in a state where the recessed spaces 21 communicate with each other in the vertical direction. Even in this buried state, the drainage resistance in the concave space 21 is small. Therefore, water near the spacer panel 2 is quickly discharged into the ground through the concave space 21. Naturally, the spacer panel 2 has sufficient strength to withstand the earth pressure, water resistance and durability.

The water permeable sheet 3 is provided in the concave space 21 described above.
This prevents the intrusion of soil into the space and increases the drainage resistance in the concave space 21 (see FIG. 2). By covering the spacer panel 2 with the water-permeable sheet 3, it is possible to prevent soil from entering the recessed space 21. On the other hand, the water-permeable sheet 3 has sufficient water-permeability as the name implies, so that the underground water is
It does not significantly impede the flow into one. Therefore, the water-permeable sheet 3 needs to be made of a material that allows water to easily pass through, but has many holes that cannot pass through the soil particles.

As described above, the water permeable sheet 3 is kept under the earth pressure (for example, 500 kg / m ² ) while maintaining sufficient water permeability.
, The concave space 21 must be maintained for a long period of time. In the present embodiment, as a material having such characteristics, the water-permeable sheet 3 is formed of a nonwoven fabric.

Next, the cover member 4 will be described with reference to FIG.

The cover member 4 extends from the upper end of the separator 1
This is to prevent earth and sand, rainwater, and the like from entering the gap between the spacer panel 2 and the wall surface w. The cover member 4
As shown in FIG. 4, the fixing portion 40, the intermediate portion 41,
And a holding portion 42. The fixing portion 40 is a portion fixed to the wall surface w. The intermediate portion 41 is a portion that covers the upper end portion 10 of the separator 1. The holding portion 42 is a portion that holds the upper end 10 (see FIG. 1) of the separator 1. The cover member 4 includes a fixed portion 40, an intermediate portion 41, and a pressing portion 42, which are integrally formed in this order. Each of these parts extends in the longitudinal direction of the cover member 4. The cover member 4 is, of course, made of a water-impermeable material.

The “recess” in the claims corresponds to the recess space 21 in the present embodiment. The “stack” corresponds to the separator 1.

The separator 1 and the cover member 4 according to the present embodiment.
Will be described with reference to FIG.

At the time of construction, the separator 1 is appropriately cut in accordance with the construction object and construction environment. Then, it is buried along the wall surface w. In this case, the cut end face is buried in an orientation such that the cut end face is located on the upper side (that is, in such a direction that the cut end face can be suppressed by a cover member described later). In the buried state, the upper end portion (whether or not cut) 10 of the separator 1 is exposed to the ground. In addition, a drainage path such as a pipe is provided at the lower end of the separator 1.

Subsequently, the cover member 4 is moved to its intermediate portion 41.
Is fixed to the wall w while covering the upper end 10 of the separator 1. This can prevent rainwater from entering the gap between the spacer panel 2 and the wall surface w. In this state, the pressing portion 42 holds down the upper end 10 of the separator 1 from the lateral direction. Therefore, even if the upper end of the separator 1 is cut and the upper end of the water-permeable sheet 3 is open, the opening does not open. Therefore, the sediment does not infiltrate into the separator 1 (the gap between the spacer panel 2 and the water-permeable sheet 3). In this case, if necessary, the slate plate 5 and the like may be interposed between the holding portion 42 and the separator 1 (see FIG. 1).

The underground water passes through the permeable sheet 3 and
It reaches the concave space 21. Since the concave space 21 has a small drainage resistance, the water easily flows through the concave space 21 to the above-mentioned drainage pipe or the like. Since the spacer panel 2 itself does not have water permeability, underground water does not reach the wall portion w.

According to the embodiment described above, by fixing the cover member to the wall surface, the inflow of earth and sand into the inside of the separator 1 and the gap between the separator 1 and the wall portion w can be reliably prevented. it can. Moreover, since the cover member is made of a plate material, the treatment of the upper end of the separator 1 is easy.
There is no need to cover the cutting opening with tape.

As shown in FIG. 6, the cover member 4 may be provided with a ventilation hole 43 at a portion (intermediate portion 41) covering the upper end portion 10 of the separator 1. When such a configuration is employed, moisture in the gap between the spacer panel 2 and the wall surface portion w can be quickly released to the ground, and the wall surface can be kept in a more dry state. However, in this case, it is preferable to provide a drainer 6 above the cover member 4 'in order to prevent rainwater or the like from entering through the ventilation hole 43 (see FIG. 1).

As shown in FIG. 7, a heat insulating panel 7 having excellent heat insulating properties may be arranged between the separator 1 and the wall w. In this case, the heat insulating panel 7 is disposed so as to cover the upper side of the wall portion w from the position covered by the separator 1. The cover member 4 is fixed to the heat insulating panel 7 and covers the upper end of the separator 1. The portion of the heat insulating panel 7 that is not covered with the separator 1 and the fixing portion 40 of the cover member 4 are covered with mortar or the like. In addition, as the heat insulating panel 7, for example, foamed polystyrene can be adopted. In the state after the burial, the cover member 4 and the separator 1 are completely buried in the soil. Even in this case, the cover member 4 prevents soil from entering between the heat insulating panel 7 and the separator 1.

It should be noted that the above structure refills the soil after construction. In this case, for example, as shown in FIG. Even in this case, the intrusion of soil between the heat insulating panel 7 and the separator 1 is prevented by the cover member 4. This is not limited to the case where the heat insulating panel 7 exists as shown in FIG. 7, and the same applies even when the heat insulating panel 7 is not provided.

In the above-described embodiment, the drainage path such as a pipe is provided at the lower end of the separator.
Not limited to this. For example, below the separator, the gravel is placed in a state of being covered with a permeable sheet, and the drain is provided by communicating with the concave space inside the separator, and the water in the drain is supplied through a pipe or the like. Or let it drain naturally
A structure in which water is forcibly drained by a pump through a pipe or the like can be adopted.

[0038]

As described above, according to the present invention, the inflow of earth and sand can be reliably prevented by fixing the cover member to the wall surface. In addition, since the cover member is made of a plate material, it is possible to treat the upper end portion of the laminated body, which facilitates construction.

In the case where a drain is provided on the wall surface on which the laminate is mounted and the cover is covered by the drain, a ventilation hole is provided in a portion of the cover which covers the upper end of the laminate to form a spacer. Moisture in the space formed by the panels can be released to the ground, and the wall surface can be kept dry.
