Abstract

<P>PROBLEM TO BE SOLVED: To provide a waterproof floor with a draining gradient, which facilitates construction thereof even if a gradient area is large. <P>SOLUTION: The waterproof floor with a draining gradient is formed by laying substrate plywood (not shown) on frames 4, and then arranging slope face plates 10, 30, and a flat face plate 20 on the plywood. Each slope face plate 10 exhibits a trapezoidal longitudinal section inclining along a draining gradient direction, and has an upper surface 11 having the draining gradient, a horizontal lower surface 12, and an upstream-side end face 13 and a downstream-side end face 14. When a tongue joint portion 15 of the slope face plate 10 is fitted into a groove joint portion 16 of the adjacent slope face plate 10, upper surfaces 11, 11 of the respective slope face plates 10, 10 form a continuous surface. To construct the waterproof floor, one of the slope face plates 10 is laid adjacently to a drain gutter 5, and another one of the slope face plates 10 and one of the face plates 20 are laid adjacently to the former slope face plate, followed by laying another one of the slope face plates 10 and two of the flat face plates 20 are laid adjacently to the former ones. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a waterproof floor having a drainage gradient.

  A technique for constructing a waterproof floor having a drainage gradient using a flooring with a drainage gradient or a waterproof pan is described in JP-A-5-98680 and JP-A-8-120724.

  In the former Japanese Patent Laid-Open No. 5-98680, a plurality of waterproof pans with drainage gradients are arranged adjacent to each other while adjusting the height with foot bolts so that their upper surfaces are continuous surfaces.

In the latter Japanese Patent Laid-Open No. 8-120724, a waterproof floor with a drainage gradient is constructed by laying a relatively large piece of slope face material having an upper surface with a drainage gradient.
JP-A-5-98680 JP-A-8-120724

  When constructing a waterproof floor with a drainage gradient by the technique of the above-mentioned JP-A-5-98680, it is necessary to strictly adjust the height with the foot bolt so that the upper surface of the adjacent waterproof pan becomes a continuous surface, and the construction work It takes time and effort.

  In the technique of the above-mentioned JP-A-8-120724, the size of the waterproof floor with a drainage gradient is limited to the size of one slope face material, and a waterproof floor with a drainage gradient with a large area cannot be constructed. .

  An object of the present invention is to provide a waterproof floor with a drainage gradient that can be easily constructed even if it is a waterproof floor with a large area drainage gradient.

  The waterproof floor with drainage gradient of the present invention (Claim 1) is a waterproof floor with drainage gradient in which a slope face material having an upper surface with a drainage gradient is laid and a waterproof layer is formed thereon. The face materials are arranged such that each upper surface is a continuous surface, and a flat surface material having a horizontal upper surface is laid below the slope surface material on the water side.

  The waterproof floor with drainage slope according to claim 2 is characterized in that, in claim 1, the vertical cross-sectional shape along the drainage slope direction of the slope face material is trapezoid, and the thickness of the water-side top end of the slope face material is a, water The sum of b and c is approximately equal to a, where b is the thickness of the lower end and the thickness of the flat face material is c.

  The waterproof floor with a drainage gradient according to claim 3 is the actual floor according to claim 2, wherein the water bottom slope face material and the water bottom slope face material are engaged with each other. A part is provided.

  In the waterproof floor with a drainage gradient according to the present invention, a plurality of slope face members are laid so that the upper surface is a continuous surface, so that a waterproof floor with a drainage gradient having a desired size can be constructed.

  In the present invention, since the flat face material is laid on the lower side of the slope face material on the water side, the slope face material can be easily installed with a predetermined gradient. In particular, the vertical cross-sectional shape along the direction of drainage gradient of the slope face material is trapezoidal, and the relationship between the thickness a of the water-side end of the slope face material, the thickness b of the water-side end face, and the thickness c of the flat face material By setting a≈b + c, the upper surface of the adjacent slope face material can be easily made continuous.

  In the present invention, by providing a real part engaged with each other on the water-side slope part of the water-side slope face material and the water-side slope part of the water-side slope face material, adjacent slope face materials It is possible to make the upper surface a continuous surface very easily. It is also possible to increase the connection strength between adjacent slope face materials.

  It is desirable that the slope face material itself has a waterproof function. The waterproof treatment of the joint of the slope face material is preferably performed by a rubber ass type tape, a butyl tape, or a seal material, and a cement base board is adhered and fixed thereon, but is not limited thereto.

  In addition, when the slope face material does not have a waterproof function, it is possible to apply a waterproof sheet such as a sheet waterproof, a waterproof coating, and an FRP on-site strike. After laying the slope face material, if necessary, it may be subjected to a primer treatment, and a waterproof sheet may be pressure-bonded or a urethane coating may be applied.

  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a waterproof floor with a drainage gradient according to the embodiment, FIG. 2 is a side view of a slope face material and a flat face material, FIG. 3 is a perspective view of the slope face material, and FIG.

  As shown in FIG. 1, a gantry 4 is installed in a bathroom construction planned space 3 surrounded by a concrete floor 1 and a pillar or waist wall 2. The gantry 4 is made of a frame such as a girder, for example, and is installed on the concrete floor 1 by foot bolts or legs (not shown). After laying a base plywood (not shown) on the gantry 4 as necessary, a waterproof floor with a drainage gradient is formed by the slope face members 10 and 30 and the flat face member 20. A drainage basin 5 is disposed between the slope face members 10 and 30, and a drainage pipe 7 is connected to a drainage trap 6 provided in the drainage basin 5.
