[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spring treatment method, a spring treatment panel, and a spring treatment structure, and more particularly, to a spring treatment method, a spring treatment panel, and a spring treatment method for forming a spring passage below a floor slab. Spring water treatment structure.

[0002]

BACKGROUND OF THE INVENTION In general,
In the case where the floor surface is below the water level in an underground parking lot or the like, spring water leaks from a wall surface, a bottom plate, or the like, so that spring water treatment is required.

[0003] In this spring treatment, for example, as shown in FIG. 8, a spring treatment panel 14 having a large number of projections 12 protruding toward the bottom 10 is laid on the bottom 10 and this spring treatment is performed. Concrete is cast on the panel 14 to form the floor slab 16.

A space between the bottom plate 10 formed by the convex portions 12 and the spring treatment panel 14 is used as a spring water passage 18.

[0005] However, when such a spring treatment panel 14 is used, the uneven portion 2 due to construction errors is formed on the surface of the bottom plate 10.
If there is 0, the spring treatment panel 14 and the bottom plate 10 are separated from each other, and when the wheel load 22 of the automobile is applied to the floor slab 16 in this portion, as shown in FIG. Will occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a spring treatment method capable of reliably supporting a spring treatment panel on the bottom even when the bottom has an uneven portion, thereby preventing cracks in the floor slab due to wheel loads. It is to provide a water treatment panel and a spring treatment structure.

[0007]

In order to achieve the above-mentioned object, the spring water treatment method of the present invention constructs a bottom plate capable of being drained into a spring pit at a height equal to or lower than a water level while being surrounded by a wall. And a step of laying a spring treatment panel on the bottom plate, and a step of casting concrete on the spring treatment panel to form a floor slab, wherein the bottom plate and the spring treatment panel In the spring treatment method in which a spring water passage is formed between the spring treatment panels, the spring treatment panel has a large number of projections projecting toward the bottom plate side and having through holes formed at the tips, thereby forming the floor slab. In the process, the concrete is caused to flow out to the bottom side from the through hole of the spring treatment panel to form a support portion of the convex portion on the bottom side.

According to the present invention, the concrete for forming the floor slab flows out from the through-hole of the spring water treatment panel to the bottom side to form a support portion of the convex portion of the spring water treatment panel on the bottom floor. Even if there is an uneven area due to construction errors on the surface of the floor, the floor slab concrete support part reliably supports the spring treatment panel, so cracks occur in the floor slab even if a wheel load is applied on the floor slab Can be prevented.

Further, since the support portion is formed independently by casting concrete for the floor slab, the construction can be performed very easily.

[0010] In this case, if the floor slab constitutes the floor of the underground structure, it is possible to perform a spring water treatment without cracks.

[0011] Further, by using the underground structure as an underground parking lot, it is possible to reliably prevent the occurrence of cracks in a floor slab to which a wheel load is applied.

The spring treatment panel of the present invention is a spring treatment panel used in the spring treatment method, and has a large number of projections which are depressed on the upper surface side and project downward. A through hole is formed at the protruding tip to allow the concrete for forming the floor slab cast on the upper surface to flow to the lower bottom side to form a support portion of the projection on the bottom side. .

According to the present invention, with a simple configuration in which a through hole is formed at the protruding tip of each projection, the support for supporting the projection is reliably provided on the bottom, in order to cope with irregularities on the surface of the bottom. By forming, cracks in the floor slab can be reliably prevented.

In this case, it is preferable that a reinforcing rib is formed upright around the upper surface of the through hole so as to reinforce the convex portion.

[0015] Further, the concrete outflow hole is formed at a position corresponding to the through hole, and a sheet for preventing the concrete from entering between the convex portions is provided over the entire lower surface at a tip position of the convex portion. Is preferred.

In this way, the support portion can be reliably formed below the convex portion without the concrete flowing out below the convex portion entering between the convex portions.

The spring water treatment structure of the present invention is a spring water treatment structure formed by the above-mentioned spring water treatment method, comprising: a bottom plate formed so as to be able to drain into a spring pit; A spring treatment panel laid on the bottom with a number of projections having holes formed thereon, and a spring passage formed on the bottom with the number of projections, and a spring treatment panel on the spring treatment panel. A floor slab formed by casting concrete, and a support for the convex portion formed on the bottom plate by allowing the concrete forming the floor slab to flow out of the through-hole of the spring treatment panel to the bottom plate side. And characterized in that:

According to the present invention, the concrete forming the floor slab is caused to flow out of the through-hole of the spring treatment panel to the bottom side, and the convex portion formed on the bottom side supports the convex portion on the bottom side to make the surface uneven. Irrespective of the presence of the portion, the projection can be reliably supported to prevent the floor slab from cracking.

According to the present invention, in the spring treatment panel, the concrete outflow hole is formed at a position corresponding to the through hole, and a sheet for preventing the concrete from entering between the protrusions is provided at a tip position of the protrusion. In this case, it is preferable to be provided over the entire lower surface.

In this way, the support portion can be reliably formed below the convex portion without the concrete flowing out below the convex portion entering the space between the convex portions.
