DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a case where a so-called artificial ground is formed in which a large-sized parking lot or the like is formed at a lower portion and a park having a hill, a forest, a river, a pond or the like is formed at an upper portion. More particularly, the present invention relates to a useful floor structure in which a waterproof layer is provided on an upper surface of a slab forming a space at a lower portion, and a surface material is provided on the upper surface of the waterproof layer.

[0002]

2. Description of the Related Art The above-mentioned artificial ground has an advantage that the environment can be improved while effective use of land can be achieved. In making the artificial ground, a water leakage accident is likely to occur because a pond or a river is formed in an upper part. Taking into account the conditions, sufficient measures have been taken to prevent leakage. However, considering that the waterproof layer is likely to be degraded or damaged, the water leaking from the damaged part of the waterproof layer flows along the reinforcing bars of the slab, but the flow destination is unknown, and the bottom of the slab is unknown. There is a case where a water leakage phenomenon of leaking out of water occurs, and there is a case where such a phenomenon does not occur, and it is very difficult to reliably capture the water leakage itself. In addition, since the flow destination of the water leaked from the damaged portion of the waterproof layer is unknown, even if it is found that the leak phenomenon has been embodied and the water leak has occurred, the leak location is not known and the slab is not detected. It is necessary to take very large measures to prevent water leakage, such as removing all surface materials from the area and searching for water leakage points.

[0003]

SUMMARY OF THE INVENTION The present invention focuses on the above points, and an object of the present invention is to provide a floor structure capable of early detection of water leakage and easily detecting a leakage point. The point is to provide.

[0004]

A feature of the floor structure according to the first invention of the present invention is that a drainage portion is formed at a set point of the slab, and a water permeable layer is formed between the upper surface of the slab and the waterproof layer. The point is that a water gradient to the drainage part is formed on the upper surface of the slab. A feature of the floor structure according to the second invention of the present invention is that, in the first invention, the slab is partitioned into a plurality of areas, and a drainage section, a water permeable layer, and a water gradient are formed for each section. is there.

[0005]

According to the first aspect of the present invention, when a water leaking portion is formed in the waterproof layer, the water entering from the water leaking portion has a flow direction defined by the water gradient of the slab, and is discharged along the water permeable layer along the drainage portion. And then discharged. Therefore, the presence or absence of water leakage can be determined by monitoring the presence or absence of drainage from the drainage unit. According to the second aspect, the presence or absence of water leakage can be determined for each of the sections corresponding to each of the drains, based on whether or not there is drainage from each of the drains corresponding to each of the sections.

[0006]

Therefore, according to the first aspect of the present invention, it is possible to detect a water leak early and surely, and according to the second aspect, it is possible to detect a water leak in a unit of a section, which is a large scale. The location of the leak can be specified with good workability without the need for construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an artificial ground comprises a reinforced concrete slab 2 as a floor, which forms a parking space 1 as a space at a lower portion. Lower slab 2A that covers the upper slab and upper slab 2B that is integrally connected to the lower slab 2A and has an upper surface formed in an uneven shape.
Consists of The upper surface of the slab 2 is provided with a waterproof layer 3 made of asphalt or the like, and the upper surface of the waterproof layer 3 is provided with a surface material 7 forming a pond 4, a river 5, an island 6, and the like.
Is installed. The surface material 7 forms a water area such as the pond 4 or the river 5 and a soil area such as the island 6, and also includes a pressing concrete 7 </ b> A for covering and protecting the upper surface of the waterproof layer 3 and a soil 7 </ b> B buried thereabove. Consists of Then, as shown in FIG. 2, a ridge 2 a for dividing the slab 2 into a plurality of areas A is formed in the slab 2, and a pipe 8 penetrating the slab 2 is provided at a set position in each of the areas A. And a drainage part 9 for draining to the parking lot 1 is formed. A water permeable layer 10 is formed between the upper surface of the slab 2 and the waterproof layer 3. A water gradient to the drain section 9 is formed. In other words, when a water leakage point occurs in the waterproof layer 3, the water leakage in
It is configured to flow down to the drainage unit 9 through the outlet 0. The water permeable layer 10 is made of a nonwoven fabric. In order to ensure that the corners formed on the upper surface of the slab 2 are waterproofed by the waterproof layer 3, the angle θ of the surfaces forming the corners is obtuse. Is configured. Therefore, according to the above embodiment, when water leakage occurs, the area A where the water leakage occurs
The water is discharged from the drainage section 9 of the first embodiment, whereby it is possible to know that a leak has occurred and the section A where the leak has occurred.

[Alternative Embodiment] In the above embodiment, as shown by a two-dot chain line in the figure, a gutter 11 for receiving drainage from the drainage portion 9 and discharging it to a predetermined location is provided. In the above embodiment, a sensor for detecting drainage from each of the drainage units 9 is provided, and a notification device that operates based on the detection of these sensors is provided. The alarm device may simply notify the occurrence of water leakage by operating an alarm device such as a buzzer sound or lighting of a lamp. It is better to report whether it has occurred. In the above embodiment, the parking space is shown as the space 1 below the slab 2, but the space 1 may be used for living or passing. In the above embodiment, the slab 2 is divided into a plurality of sections.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
