構造及び施工方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is laid under the floor of a building basement to secure a drainage channel for spring water, condensed water, etc.
The present invention relates to a drainage panel made of a synthetic resin foam plate, a drainage floor structure using the same, and a construction method.

る。2. Description of the Related Art In a basement of a building, a drainage pit is provided between a foundation slab and a floor slab to discharge spring water and condensed water, and the spring water and condensed water collected in this drainage pit are discharged by a drainage pump. It is common to allow it to be discharged to the ground.

公昭６３−１６５３７号公報）。Therefore, in order to secure a drainage channel for collecting water under the floor without taking up a space like a drainage pit, drainage grooves that open to the sides are formed vertically and horizontally on the lower surface of the synthetic resin foam plate. Drainage panels are laid out on the foundation slab while leaving some vacant spaces, and after directly arranging the slabs on it, concrete is laid to build the floor slab and the vacant spaces left when laying the drainage panels. Concrete poured into the
A drainage method has been proposed in which a columnar portion is formed to connect the foundation slab and the floor slab and prevent displacement of the drainage panel (Japanese Patent Publication No. 63-16537).

排水路を確保することができる。That is, according to this construction method, since the drainage groove formed on the lower surface of the drainage panel remains as a drainage channel even after the floor slab is constructed, it is possible to guide the water to a predetermined water collecting portion through the drainage groove. The drainage can be secured in a small space under the floor.

ルの排水溝間の連結が断たれてしまうことも生じる。However, since the drainage panel used in the above-mentioned conventional drainage construction method has the drainage groove opened on the side surface, when the drainage panels are laid out, the positions of the openings of the drainage groove are not aligned with each other. If it shifts, the drainage channels of adjacent drainage panels will be disconnected from each other and will not function as a drainage channel. Therefore, it is necessary to lay the drainage panel while aligning the positions of the openings of the drainage grooves, which causes a problem that this laying is troublesome. In addition, even if the drainage panel is laid by aligning the positions of the openings of the drainage channels, the worker will ride on the drainage panel when placing reinforcements and concrete, and the drainage panel will be displaced. The connection between the drains of adjacent drainage panels may be broken.

同様の問題を生じている。On the other hand, the condensed water or spring water generated on the wall surface of the basement is guided to the drainage channel of the drainage panel through the drainage duct, and in this case also, if the positions of the drainage duct and the drainage channel are misaligned, they function as drainage channels. Is lost, causing the same problem as above.

柱状部分が邪魔になる問題もある。Further, the drainage channel formed by the drainage groove of the drainage panel is partially blocked in order to connect the foundation slab and the floor slab and to partially form the columnar portion for preventing the displacement of the drainage panel. There is also a problem that this columnar part becomes an obstacle in terms of drainage function.

The drainage panel A is made of a synthetic resin foam plate, and a drainage groove 1a that is open to the outside is formed by notching the corners along the entire peripheral edge of the lower surface. . Further, also on the lower surface, drainage grooves 1b whose end portions are connected to the peripheral drainage grooves 1a are formed vertically and horizontally.

る。The drainage panel A is laid on the foundation slab 2 as shown in FIG. 2, and since the drainage groove 1a whose outer side is open is formed at the entire periphery, the drainage panels adjacent to each other are drained. Regardless of the plane positional relationship between the panels A, the drainage grooves 1a of the adjacent drainage panels A are always connected. Therefore, the drainage grooves 1a at the periphery of each drainage panel A laid on the foundation slab 2 are in communication with each other,
It constitutes a drainage channel that guides spring water and condensed water to a predetermined position.

However, since it is difficult to secure a sufficient amount of drainage only with the drainage groove 1a, it is preferable to increase the drainage area with respect to the floor area to secure a sufficient drainage capacity. Further, since the drainage grooves 1a on the peripheral edge communicate with each other regardless of the planar positional relationship between the adjacent drainage panels A, the drainage grooves 1b on the vertical and horizontal sides of each drainage panel A communicating with the drainage groove 1a on the peripheral edge. Will also communicate with each other.

る。As the synthetic resin foam constituting the drainage panel A, for example, foams of polystyrene, polyurethane, polyethylene, polyvinyl chloride, phenol resin, etc. can be used, but they are excellent in pressure resistance and have low hygroscopicity. Therefore, a closed cell extruded foamed molded article is preferable. In particular, the water absorption rate is 0.01 or less, and the compression strength is 2.5 to
A polystyrene extruded foamed product having a foaming ratio of 20 to 40 times, which is 10 kgf / cm 2 , is preferable. In the drainage panel A according to the present invention, the drainage groove 1a is formed on the entire peripheral edge of the lower surface, so that the peripheral edge portion is thin. In the case of a bead foam molding having a low pressure resistance, an operator may get on the reinforcement 6 (see FIG. 4) or when placing concrete thereafter, which may cause cracks or chips at the peripheral edge. However, when it is made of an extruded foam molded article having excellent pressure resistance strength, particularly a polystyrene extruded foam molded article having an expansion ratio of 20 to 40 times, this cracking or chipping can be prevented.
【００１８】本排水パネルＡの平面形状は、一般的には

The thickness is preferably about mm, and more preferably about 20 to 30 mm. The width w a of the peripheral drainage groove 1a may be equal to the width of the vertical and horizontal drainage grooves 1b, but if the width w a of the drainage groove 1a is set to ½ of the width w b of the drainage groove 1b. After laying the drainage panel A, the width of all drainage channels formed by the drainage grooves 1a and 1b can be made substantially equal.

The drainage grooves 1a and 1b of the panel A have a triangular cross section. In particular, when the drain groove 1b formed vertically and horizontally has a triangular cross section, when the size of the drainage panel A is adjusted on site, the drainage panel A is manually held by the cut line 10 as shown by the dotted line in FIG. There is an advantage that it is easy to divide and adjust the size.
【００２４】次に、図４に基づいて本発明の排水性床構

【００２５】本排水性床構造は、基礎スラブ２上に敷設

もので次の手順で施工されるものである。This drainage floor structure is constructed by constructing the floor slab 3 on the above-mentioned drainage panel A laid on the foundation slab 2 and is constructed by the following procedure.

よい。First, the drainage panel A is laid on the foundation slab 2. The drainage panel A shown in FIG. 4 has both the drainage groove 1a at the peripheral edge and the drainage grooves 1b in the vertical and horizontal directions, but as described above, it may be only the drainage groove 1a.

結されるので、例えば千鳥状等の並べ方も可能である。The drainage panels A are generally arranged in a straight line in the vertical and horizontal directions. However, in the case of the drainage panels A, the drainage of the adjacent drainage panels A is irrespective of the plane positional relationship between the adjacent drainage panels A. Since the grooves 1a (and the drain grooves 1b) are always connected to each other, it is possible to arrange them in a staggered pattern, for example.

同様の理由から粘着テープ４で覆う。After laying drainage panel A, drainage panel A
The seam between them is covered with adhesive tape 4. This is because in the drainage floor structure, the drainage channel 1a is located immediately below the drainage panel A over the entire length of the joint between drainage panels A. This is because when the water flows into the drainage groove 1a, the formed drainage channel is divided and the drainage becomes incomplete. In addition, the joint between the drainage panel A and the surrounding building structure portion such as the inner wall portion 5,
For the same reason, it is covered with the adhesive tape 4.
【００２９】次いで、敷設した排水パネルＡ上に配筋６

It is necessary to provide the bar 6 a little above the drainage panel A by providing the bar arrangement 6 or the like. This is because the reinforcing bar 6 is the reinforcing bar 6 in the slab included in the cross section of the floor slab 3. By doing so, the load applied to the floor slab 3 is surely applied to the entire floor slab 3. It can be dispersed, and the drainage panel A can be prevented from being crushed by the load applied to the floor slab 3.

でき、排水機能を向上させることができる。In particular, a building basement to which the drainage floor structure of the present invention is applied is often used as a parking lot, and a large weight is often applied to the floor slab 3. In order to endure such a large load, the drainage panel A is preferably an extruded foam molded product as described above, and particularly preferably a polystyrene extruded foam molded product having a foaming ratio of 20 to 40 times. And, the reinforcing bar in the slab 6
If the drainage panel A made of this extruded foam molded article is adopted to enhance the pressure resistance, the drainage panel A according to the present invention will be improved.
Since it is not necessary to prevent the slippage, it is possible to adopt a drainage floor structure in which the drainage panel A is laid on the entire surface of the foundation slab 2 without forming a columnar portion unlike the conventional drainage construction method. Can be improved.
