DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to drainage and water collection, for example, on the rooftop, balcony, bathroom and garage floors, poolside, and workplace floors that use large amounts of water for food processing. A water gradient surface, which is a surface of a graded construction that guides the flow of water for the surface.

[0002]

2. Description of the Related Art Conventionally, in order to form a slope of a roof, which is one of the water slopes, it has been known to use a synthetic resin foam molded product having a slope as a base (see Japanese Utility Model Publication No. Sho 54/78). No.-9379).

By the way, even if the synthetic resin foam molded article is used as a base as described above, it is not possible to cover the entire surface with one synthetic resin foam molded article. The base plate is formed in a required range by combining the synthetic resin foam gradient plates having the thicknesses of 4 to 7 types and the synthetic resin foam flat plates having upper and lower surfaces that are both horizontal.

On the other hand, a conventional gradient plate is prepared by cutting an original plate of a synthetic resin foam formed by extrusion foaming into an appropriate size,
It is manufactured by cutting this cut original plate obliquely in the horizontal direction using a hot wire at a line different from the extrusion foaming molding, and making the diagonal cut surface a slope.

[0005]

However, the water gradient is usually a small gradient of about 1/100 to 2/100, and the gradient surface of the gradient plate also has a small gradient corresponding to this. The inclination direction is difficult to understand,
There is a problem that the inclination direction is easily mistaken during construction.

If the inclination direction is printed on the surface of the gradient plate, such an error can be prevented, but such printing is not performed because it is difficult to print on the inclined surface.

In addition, in the conventional production of a gradient plate, a gradient surface is formed by a line different from the extrusion molding of the original plate and by a hot wire having a low cutting speed, so that the production efficiency is low and the production efficiency is low. In addition, since the melt-solidified (skin) layer is formed under the influence of the heat of the heat rays when forming the gradient surface, there is a problem that the obtained gradient plate is likely to be warped.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to clarify the direction of inclination of a gradient surface in a gradient plate, to minimize the types of gradient plates required for the foundation work, and to provide a gradient plate. An object of the present invention is to improve manufacturing efficiency.

The first aspect of the present invention relates to a gradient plate 2 in which the inclination direction of the gradient surface 1 is clarified, wherein one surface is inclined in one direction.
The inclined surface 1 is inclined , and the other surface is a horizontal surface 3. The inclination direction of the inclined surface 1 is displayed on the horizontal surface 3, with the horizontal surface 3 facing upward.
This is a gradient plate 2 used in the present embodiment (see FIG. 1).

On the lower side of the water gradient surface, the ground gradient plate 2 with the horizontal surface facing up

See).

[0011]

According to the first aspect of the present invention, the fact that the inclination of the inclined surface 1 of the inclined plate 2 is so small that the inclination direction is erroneously made is utilized in reverse. Incidentally, in FIG. 1, the slope of the slope surface 1 is emphasized for convenience of explanation, but the actual slope is shown in FIG.
It is of the degree shown in. Therefore, originally, the slope 1
Should be laid up, but even if it is laid with the horizontal plane 3 up, the deviation caused by reversing the inclined plane 1 and the horizontal plane 3 is negligible and has little effect on the formation of the water inclined plane. . The invention of claim 1 makes use of this fact, and
The inclination direction of the slope 1 is displayed, and the horizontal plane 3 is set upward.
It is intended to be laid .

In the invention of claim 7 , the slope 1 is formed by using the band saw 6a because the slope plate 1 is formed by using equipment provided in a usual extrusion foaming equipment. 2 can be manufactured, the cutting efficiency is improved, and the influence of heat is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1A, the present gradient plate 2
Is a gradient surface 1 with one surface inclined in one direction, and a horizontal surface 3 with the other surface
It has become. Further, on the horizontal plane, the inclination direction of the inclined plane 1 is displayed as shown in FIG. This display may be any display as long as the tilt direction can be known. In this embodiment, the tilt direction is displayed by printing an arrow.

The gradient plate 2 is made of a synthetic resin foam. Examples of the synthetic resin foam include foams such as polystyrene, polyurethane, polyethylene, polyvinyl chloride, and phenol resin, and foams obtained by adding an inorganic filler to these synthetic resins. Extruded polystyrene such as Styrofoam (trade name) is preferred from the viewpoints of low water absorption, workability and the like.

The shape and size of the present gradient plate 2 depend on the construction site and the like, but are usually square with a side of about 45 to 200 cm. Further, it is preferable that the slope of the slope 1 be 1/100 to 2/100 corresponding to the slope of the normal water slope.

Next, an example of use of the above-mentioned gradient plate 2 will be described with reference to FIGS.

The ground on the water gradient surface shown in FIG. 5 is constructed by combining the gradient plate 2 shown in FIG. 3 and the flat plate 4 shown in FIG. That is, the gradient plate 2 is laid at the lowest part of the water gradient surface to be formed so that the inclination direction of the gradient surface 1 is aligned with the inclination direction of the water gradient surface to be formed. Gradient plate 2 on flat plate 4
Are laid in the same way, and connected to the back,
The gradient plate 2 is laid on the stacked flat plates 4 while increasing the number of the flat plates 4 by one.

The gradient plate 2 and the flat plate 4 are both made of a synthetic resin foam as described above, and the height of the rear end of the gradient plate 2 (the end of the inclined surface 1 in the inclined upper direction) is H. ₁ , when the height of the tip of the gradient plate 2 (the end of the gradient surface 1 in the direction of the lower slope) is h ₁ and the thickness of the flat plate 4 is t ₁ , t ₁ = H ₁ −h
One in which has become _1. Therefore, the upper surfaces of the respective gradient plates 2 are arranged in a series to form a series of inclined surfaces.

On the ground of the water gradient surface, the gradient plate 2 and the flat plate 4 are sequentially laid from the lowest portion to the highest portion of the water gradient surface to be formed, and the gradient plate 2 and the flat plate 4 are laid at the highest portion of the water gradient surface. It can be easily formed by cutting and flattening the flat plate 4.
That is, first, the gradient plate 2 is laid on the lowest part of the water gradient surface to be formed to be the first stage, and then connected to the first stage, the gradient plate 2 is laid on the flat plate 4 and the gradient plate 2 is laid in the same manner. In the third and subsequent stages, the gradient plate 2 is similarly laid while increasing the number of the flat plates 4 to be overlapped one by one, and is easily formed by cutting and aligning the gradient plate 2 and the flat plate 4 at the highest part of the water gradient surface. be able to.

In particular, when the gradient plate 2 in which the inclination direction of the gradient surface 1 is displayed on the horizontal plane 3 is used, the above-mentioned gradient plate 2 is laid.
The operation is performed with the horizontal plane 3 on which the display is made upward. In this way, the inclination direction of the gradient plate 2 is not easily mistaken at the time of construction, and the inclination direction of each gradient plate 2 can be easily confirmed during construction of the foundation and even after completion of the foundation.

In this example, the length of the flat plate 4 is twice the length of the gradient plate 2 so that the number of times of laying the flat plate 4 can be reduced. Is also good. When the flat plate 4 and the gradient plate 2 have the same length, the flat plates 4 having thicknesses t ₁ , 2t ₁ , 3t ₁ ,.
It is also possible to use only one flat plate 4 after the step.

The water gradient surface can be formed by providing a waterproof layer over the base of the formed water gradient surface and then providing a surface layer. The waterproof layer can be formed, for example, by laying asphalt roofing, a synthetic resin film or sheet, a rubber sheet, or the like. In addition, the surface layer can usually be formed by applying concrete along the slope, and furthermore, a tile, a stone plate, or the like can be additionally provided thereon, or a lining can be provided.

Another example of use will be described with reference to FIGS.

The ground on the water gradient surface shown in FIG. 9 is constituted by combining the thin and thick gradient plates 2a and 2b shown in FIGS. 6 and 7 with the flat plate 4 shown in FIG. Is what it is. That is, at the lowest part of the water gradient surface to be formed, thin and thick gradient plates 2a and 2b are successively laid so that the inclination direction of the gradient surface 1 is aligned with the inclination direction of the water gradient surface to be formed. , Connected to the back end, one flat plate 4
Similarly, thin and thick gradient plates 2a and 2b are sequentially laid on the upper side, and further connected to the rear side, and the number of the two, three and four flat plates 4 is increased one by one on the stacked flat plates 4. Thin and thick gradient plates 2a and 2b are sequentially laid.

Thin and thick gradient plates 2a, 2b and flat plate 4
Are all those which are made of synthetic resin foam such as described above, the rear end of the rear end height of the thin gradient plate 2a H _2, h ₂ a tip height of the thick gradient plate 2b When the height is H ₃ , the tip height is h ₃ , and the thickness of the flat plate 4 is t ₂ , h ₃
= H ₂ and t ₂ = H ₃ −h ₂ . Therefore, the upper surfaces of the respective gradient plates 2 are arranged in a series to form a series of inclined surfaces.

On the ground of the water gradient surface, thin and thick gradient plates 2a, 2b and a flat plate 4 are sequentially laid from the lowest portion to the highest portion of the water gradient surface to be formed. It can be easily formed by cutting and aligning the thin or thick gradient plates 2a, 2b and the flat plate 4 at the highest part. That is,
First, a thin gradient plate 2a is formed on the lowest part of the water gradient surface to be formed.
Is laid to the first stage, and then connected to the back, and a thick gradient plate 2b is similarly laid to the second stage to form the third stage and the fourth stage.
In the step, the flat plate 4 is laid, and the thin and thick gradient plates 2a,
2b are sequentially laid, and the flat plate 4
Similarly, thin and thick gradient plates 2a and 2b are sequentially laid while increasing the number of the gradient plates one by one.
And the flat plate 4 can be easily formed.

In the above construction, the thin and thick gradient plates 2a, 2b whose inclination direction of the gradient surface 1 is indicated on the horizontal plane 3
Is used, the thin and thick gradient plates 2a and 2b are laid with the indicated horizontal plane 3 facing upward in the same manner as the above-described foundation.

In particular, when the thin and thick gradient plates 2a and 2b are used as shown in FIGS. 6 to 9, a flat plate is used as compared with the case where one kind of gradient plate 2 described with reference to FIGS. 4 has an advantage that it is easy to take a large thickness. That is, those of Figures 3-5, the inclination of the inclined surface 1 is reduced, compelling difference Without increasing the length of the slope plate 2 H ₁ and h ₁ is small, even smaller thickness of the flat plate 4, a large When the flat plate 4 is formed, it is easily broken and becomes difficult to handle. Than that of FIGS. 6-9 contrast, the thin and the thick gradient plate 2a, the difference between h ₂ and H ₃ is relatively large even without much longer 2b individual lengths, the problems It does not occur.

In this example, the length of the thin gradient plate 2a and the thickness of the thick gradient plate 2b are the same, and the length of the flat plate 4 is the length of the thin and thick gradient plates 2a and 2b. Although the number of laying of the flat plate 4 can be reduced, the flat plate 4 and the thin and thick gradient plates 2a and 2b may have the same length. Further, it is also possible to prepare the flat plates 4 having thicknesses t ₂ , 2t ₂ , 3t _2, ..., Respectively, and use only one flat plate 4 for the third and subsequent stages.

The formation of the water gradient surface using the base of the main water gradient surface can be performed in the same manner as described with reference to the base of FIG.

The original plate 5 may be one whose upper and lower surfaces have been cut or cut so as to have a predetermined thickness, or may be in an extruded and foamed state.

The original plate 5 is sandwiched between the upper and lower pressing rolls 8 and sent to the band saw 6a, and a substantially central portion of the thickness thereof is cut obliquely in the horizontal direction as shown in FIG. You. When the original plate 5 is still extruded and foamed, the upper and lower surfaces are cut or cut after the diagonal cutting to adjust the thickness.

The diagonal cutting by the band saw 6a forms the inclined surface 1 of the present gradient plate 2. By this cutting, the two gradient plates 2 are stacked with the inclined surfaces 1 piled up. Is obtained. That is, the diagonal cutting is to form the gradient surfaces 1 of the two gradient plates 2 at the same time. In addition, even if the cutting with the band saw 6a is performed on the extruded and foamed long original plate 5, the original plate 5 cut to a fixed length (length in the extrusion direction) after the extruded and foamed molding is cut. You may go.

When two gradient plates 2 are stacked with their gradient surfaces 1 stacked one on top of the other, the upper and lower surfaces are horizontal surfaces 3 as shown in FIG. For example, printing can be easily performed on the upper and lower horizontal surfaces 3. Therefore, by this printing, the inclination direction of the slope surface 1 can be easily printed and displayed on the horizontal surface 3 of the two slope plates 2 stacked one above the other, and cutting and printing can be performed continuously. Is also possible. In addition, the original plate 5
When cutting is performed with the band saw 6a, the printing may be performed on the upper and lower surfaces of the original plate 5 to indicate the inclination direction by this printing, and then the cutting may be performed with the band saw 6a.
