Abstract

PURPOSE:To improve production efficiency for a gradient plate, and ensure the easy execution of a work by forming an original foamed plate of synthetic resin into such a shape as having a gradient surface at one side and a horizontal surface at the other side by use of a band saw, and indicating the slope direction of the gradient surface on the horizontal surface. CONSTITUTION:An original foamed plate of synthetic resin is formed into an extruded form with an extruding machine. At this forming process, a band saw slantingly crossing the advance direction of the original plate, and another band saw horizontally crossing the direction are used to slantingly cut the plate in a crosswise direction. Two gradient plates 2 are thereby formed and made to have a gradient side 1 and a horizontal side 3. Also, the slope direction of the gradient side 1 is shown on the horizontal side 3 by such a method as printing an arrow mark. As a result, the gradient plates 2 can be kept free from warping, and an error regarding the direction of slope can be prevented in laying the plates 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to drainage and collection of water such as rooftops, balconies, bathrooms and garage floors, poolsides, and floors of work areas that use a large amount of water such as food processing. Relates to a water-gradient surface, which is the surface of the graded structure for guiding the flow of water.

[0002]

2. Description of the Related Art Conventionally, in order to form a sloped surface of a roof, which is one of water sloped surfaces, it has been known to use a synthetic resin foam molded article having a sloped surface as a base (Jitsuko Sho 54). -9379).

By the way, even if a synthetic resin foam molded article is used as a base as described above, it is not possible to cover the entire surface with a single synthetic resin foam molded article. The synthetic resin foam gradient plate of 4 to 7 different thicknesses and the synthetic resin foam flat plate whose upper and lower surfaces are both horizontal are combined to form a base in a necessary range.

On the other hand, in the conventional gradient plate, an original plate of synthetic resin foam extruded and foamed is cut into an appropriate size,
This cutting raw plate is manufactured by cutting it diagonally in the lateral direction using a heating wire in a line different from extrusion foam molding, and making this oblique cutting surface a sloped surface.

[0005]

However, the water gradient usually has a small inclination of about 1/100 to 2/100, and the inclination surface of the surface of the inclination plate also has a small inclination corresponding to the inclination. It is difficult to understand the tilt direction,
There is a problem that it is easy to make a mistake in the inclination direction during construction.

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

Further, in the conventional manufacturing of the gradient plate, since the gradient surface is formed by a line different from the extrusion molding of the original plate and by cutting with a hot wire having a slow cutting speed, the manufacturing efficiency is poor and Since the melted and solidified (skin) layer is formed by the influence of the heat of the heat ray when forming the sloped surface, there is a problem that the obtained sloped plate is likely to be warped.

The present invention solves such a problem by clarifying the inclination direction of a sloped surface in a sloped plate, minimizing the types of sloped plates necessary for construction of a base, and the sloped plate. It is intended to improve the manufacturing efficiency of.

[0009]

The invention according to claim 1 relates to a slope plate 2 in which the slope direction of the slope surface 1 is defined.
It is the gradient plate 2 in which the inclination direction of the gradient surface 1 is displayed on the horizontal plane 3 (see FIG. 1).

Further, the inventions of claims 2 and 3 relate to a method for manufacturing the gradient plate 2 with good manufacturing efficiency, and the gradient plate 2 is formed by using the oblique band saws 6a continuously with the extrusion foam molding of the original plate 5. This is a method for manufacturing the gradient plate 2 that forms the gradient surface 1 (see FIGS. 10 to 12).

[0011]

The invention of claim 1 makes use of the fact that the inclination of the inclined surface 1 of the inclination plate 2 is so small that the inclination direction is wrong. Incidentally, in FIG. 1, the inclination of the slope 2 is emphasized for convenience of explanation, but the actual inclination is shown in FIG.
The degree is shown in. Therefore, originally the slope 1
Should be laid with the horizontal plane up, but even if the horizontal plane 3 is laid up, the deviation caused by reversing the slope plane 1 and the horizontal plane 3 is very small, and there is almost no influence on the formation of the horizontal slope plane. . The invention of claim 1 uses this to lay down with the horizontal surface 3 facing up, and the inclination direction is displayed on the horizontal surface 3.

In the inventions of claims 2 and 3, the belt saw 6
The sloped surface 1 and the horizontal surface 3 are formed by using a and 6b in order to make it possible to manufacture the sloped plate 2 using equipment provided in a normal extrusion foam molding equipment and to improve cutting efficiency. It improves and eliminates the influence of heat.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the invention of claim 1 will be described with reference to FIGS.

As shown in FIG. 1 (a), the present gradient plate 2
Is a sloped surface 1 in which one surface is inclined in one direction and the other surface is a horizontal surface 3
Has become. Further, as shown in (b), the inclination direction of the sloped surface 1 is displayed on the horizontal plane. This display may be any display as long as the tilt direction can be known, but in the present embodiment, the tilt direction is displayed by printing an arrow.

The gradient plate 2 is made of synthetic resin foam. Examples of synthetic resin foams include foams such as polystyrene, polyurethane, polyethylene, polyvinyl chloride, and phenol resin, and foams obtained by adding an inorganic filler to these synthetic resins. From the viewpoints of low water absorption and processability, extruded expanded polystyrene such as Styrofoam (trade name) is preferable.

The shape and size of the gradient plate 2 depend on the construction site and the like, but are usually rectangular with one side of about 45 to 200 cm. The slope of the sloped surface 1 is preferably 1/100 to 2/100 corresponding to the slope of a normal water sloped surface.

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

The underlayer of the water gradient surface shown in FIG. 5 is formed by combining the gradient plate 2 shown in FIG. 3 and the flat plate 4 shown in FIG. That is, at the lowest part of the water gradient surface to be formed, the gradient plate 2 is 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. Gradient plate 2 on flat plate 4
Is laid in the same manner and is connected to the rear of the
The gradient plate 2 is laid on the flat plates 4 that are stacked while increasing the number of the flat plates 4 by one.

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

As a base of this water gradient surface, the gradient plate 2 and the flat plate 4 are sequentially laid from the lowest part to the highest part of the water gradient surface to be formed, and the gradient plate 2 and the flat plate 4 are formed at the highest part of the water gradient surface. It can be easily formed by cutting and aligning the flat plate 4.
That is, first, the gradient plate 2 is laid at the lowest part of the water gradient surface to be formed to form the first step, and then connected to the back of the gradient plate 2 to be stacked on the flat plate 4 and the gradient plate 2 is similarly laid to form the second step. For the third and subsequent stages, the slope plate 2 is similarly laid while increasing the number of flat plates 4 to be stacked one by one, and the slope plate 2 and the flat plate 4 are cut and aligned easily at the highest part of the water slope surface. be able to.

In particular, when the slope plate 2 in which the inclination direction of the slope surface 1 is displayed on the horizontal plane 3 is used, the slope plate 2 is laid as follows.
This is done with the horizontal plane 3 with this indication facing up. In this way, it is difficult to make a mistake in the inclination direction of the gradient plate 2 during construction, and it is possible to easily confirm the inclination direction of each gradient plate 2 during construction of the groundwork and even after completion of the groundwork.

In this example of use, 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, but the flat plate 4 and the gradient plate 2 have the same length. 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 finish each flat plate 4 after the first stage with one plate.

The water-gradient surface can be formed by providing a surface layer on the water-gradient surface that covers the base of the formed water-gradient surface. The waterproof layer can be formed by laying asphalt roofing, a synthetic resin film or sheet, a rubber sheet, or the like. Further, the surface layer can be usually formed by coating concrete along the slope, and tiles, stone plates, etc. can be additionally provided thereon, or lining can be applied.

Another example of use will be described with reference to FIGS. 6 to 9.

The underlayer of the water gradient surface shown in FIG. 9 is formed by combining the thin and thick gradient plates 2a and 2b shown in FIGS. 6 and 7 and the flat plate 4 shown in FIG. There is something. That is, at the lowest part of the water gradient surface to be formed, thin-walled and thick-walled gradient plates 2a and 2b are laid one after another so that the inclination direction of the gradient surface 1 is aligned with the inclination direction of the water gradient surface to be formed. , One flat plate 4 connected to the rear end
Similarly, thin-walled and thick-walled gradient plates 2a and 2b are sequentially laid on the upper side, and further connected to the rear of the gradient plates 2a and 2b to increase the number of the two flat plates 4 and the flat plate 4 one by one, and the flat plate 4 is stacked. The thin and thick gradient plates 2a and 2b are sequentially laid.

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

As a base of this water gradient surface, thin and thick gradient plates 2a and 2b and a flat plate 4 are sequentially laid from the lowest part to the highest part of the water gradient surface to be formed, It can be easily formed by cutting and aligning the thin or thick gradient plates 2a and 2b and the flat plate 4 at the highest portion. That is,
First, a thin-walled gradient plate 2a is formed on the lowest portion of the water gradient surface to be formed.
Is laid to make it the first step, and then a thick gradient plate 2b is laid in the same way to make it the second step, and the third step and the fourth step
In the step, a flat plate 4 is laid and a thin and thick gradient plate 2a,
A flat plate 4 which is constructed by laying 2b in sequence and stacking after the 5th stage
Similarly, thin-walled and thick-walled gradient plates 2a and 2b are laid one by one while increasing the number of water in each one, and the gradient plate 2 is placed at the highest part of the water gradient surface.
It can be easily formed by cutting and flattening the flat plate 4.

In the above construction, the thin and thick slope plates 2a and 2b in which the slope direction of the slope surface 1 is displayed on the horizontal plane 3
In the case of using, the thin and thick gradient plates 2a and 2b are laid with the indicated horizontal surface 3 facing up, as in the case of the above-described foundation work.

Particularly, 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 the gradient plate 2 described in FIGS. 3 to 5 is used. There is an advantage that the thickness of 4 can be easily taken. That is, in the cases of FIGS. 3 to 5, when the inclination of the inclined surface 1 becomes small, the difference between H ₁ and h ₁ becomes small and the thickness of the flat plate 4 becomes small unless the length of the inclination plate 2 is increased. When the flat plate 4 is used, it becomes fragile and difficult to handle. On the other hand, in the cases of FIGS. 6 to 9, the difference between h ₂ and H ₃ becomes relatively large even if the lengths of the thin and thick gradient plates 2a and 2b are not so long. It does not occur.

In this example of use, the thin-walled gradient plate 2a and the thick-walled gradient plate 2b have the same length, and the length of the flat plate 4 is the combined length of the thin-walled and thick-walled gradient plates 2a and 2b. Although the number of times of laying 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. It is also possible to prepare flat plates 4 having thicknesses of t ₂ , 2 t ₂ , 3 t _2, ... And prepare only one flat plate 4 from the third stage onward.

The formation of the water gradient surface using the foundation of the present water gradient surface can be performed in the same manner as described for the foundation of FIG.

Next, an embodiment according to the invention of claim 2 will be described with reference to FIGS. 10 and 11.

The original plate 5 may have its upper and lower surfaces cut or cut so as to have a predetermined thickness, or may be in a state of being extruded and foam-molded.

The original plate 5 is sandwiched between the upper and lower pressing rolls 8 and sent to the band saw 6a, and the substantially central portion of the thickness thereof is cut diagonally in the lateral direction as shown in FIG. It When the original plate 5 is still being extruded and foam-molded, the upper and lower surfaces are cut or cut after this oblique cutting to adjust the wall thickness.

The oblique cutting by the band saw 6a forms the sloped surface 1 of the main sloped plate 2, and by this cutting, the two sloped plates 2 are stacked with their sloped faces 1 stacked on top of each other. Can be obtained at. That is, this oblique cutting simultaneously forms the inclined surface 1 of the two inclined plates 2. Further, the cutting with the band saw 6a is performed on the original plate 5 that has been extruded and foam-molded as it is, but on the original plate 5 that has been cut into a constant length (length in the extrusion direction) after extrusion-foam-molded. You may go.

If two slope plates 2 are stacked with their slopes 1 overlapping each other, the upper and lower surfaces thereof are horizontal planes 3 as shown in FIG. For example, the upper and lower horizontal planes 3 can be easily printed. Therefore, in this printing, the inclination direction of the inclined surface 1 can be easily printed and displayed on the horizontal plane 3 of the two vertically stacked inclined plates 2, and cutting and printing can be performed continuously. Is also possible. Also, the original plate 5 with adjusted meat pressure
When cutting with the band saw 6a, the upper and lower surfaces of the original plate 5 may be displayed in the inclined direction by this printing and then cut with the band saw 6a.

Further, an embodiment according to the invention of claim 3 will be described with reference to FIGS. 12 and 13.

As shown in FIGS. 12A to 12C,
First, the original plate 5 is cut diagonally in the lateral direction by using the same band saw 6a as that described in FIG. This belt saw 6a
The diagonal cutting is performed on the upper and lower two positions of the original plate 5, and between the upper and lower two oblique cutting positions is horizontally cut by a band saw 6b that horizontally crosses the traveling direction of the original plate 5.

The state of the original plate 5 after the cutting is as shown in FIG. 13, and each of the original plates 5 separated by the oblique cutting at the two upper and lower positions and the horizontal cutting at the center is the main gradient plate 2.
It is what constitutes. That is, the inclined planes 1 of the four gradient plates 2 are formed by diagonally cutting the upper and lower two portions, and the horizontal planes 3 of the two gradient plates 2 are formed by the horizontal cutting at the center. In addition, the upper and lower two gradient plates 1
When separated as a set, the same state as in FIG. 11 is obtained. Therefore, in this state, the inclination direction of the inclined surface 1 can be easily displayed by printing on the horizontal surface 1 of each inclined plate 2.

In the above description, the upper and lower diagonal cutting is performed before the central horizontal cutting, but the upper and lower diagonal cutting and the central horizontal cutting are finally performed as shown in FIG.
As long as the cutting state as shown in FIG. Further, it is also possible to form three or more diagonal cutting points and two or more horizontal cutting points, and simultaneously form six or more gradient plates 2.
