Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing a water-permeable gutter cover, and more specifically, to a method for manufacturing a water-permeable gutter cover efficiently using a simple method. This relates to a manufacturing method.

(Prior Art) Conventionally, a gutter 1 installed on the side of a road or sidewalk to drain rainwater, etc. is made of concrete or the like and has a concave cross section, as shown in FIG. As shown in FIGS. 6 and 7, a gutter cover 5 is placed in which a reinforcing plate 3 such as an iron plate with a plurality of through holes 2 is attached or embedded in a sheet material 4 made of water-permeable powdered rubber or the like. (for example, Japanese Utility Model Publication No. 1983-43024).

Incidentally, the above-mentioned gutter cover 5 is made by adding a binder (adhesive) to water-permeable powdered rubber, for example, and smoothing it into a plate shape to produce a sheet of a predetermined thickness. Then, this sheet is sliced into a predetermined thickness using a slicer to produce a water-permeable sheet 4. The gutter cover 5 is completed by attaching this water-permeable sheet 4 to the reinforcing plate 3 having a plurality of through holes 2 as described above via an adhesive.

[Problem that the invention seeks to solve]

However, the conventional method of manufacturing the gutter cover 5 as described above has the following various problems.

(a) There are many processing steps, which increases costs.

0)) Since it is cured naturally, it takes time to complete.

(C) Since a binder (adhesive) is added to water-permeable powdered rubber and the mixture is flattened into a plate shape without pressure, the physical properties are weak and there are problems with durability.

(d) Since the water-permeable sheet 4 is bonded to the reinforcing plate 3 afterward, the adhesive strength is weak.

(d) Since the water-permeable sheet 4 is sliced, there is no surface design.

(e) If adhesive is applied to the water permeable sheet 4 side, water permeability will be impaired.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and is a method for manufacturing a water-permeable gutter cover that can be manufactured inexpensively and in a short time without impairing water permeability, and has improved durability. The purpose is to provide the following.

[Means for Solving the Problems] In order to achieve the above object, this invention places a reinforcing member in which a plurality of through holes coated with adhesive are formed at predetermined intervals in the lower mold, and A predetermined amount of a mixture of powdered rubber and a binder is poured into the mold and filled into the plurality of through holes of the reinforcing member, and the surface of the reinforcing member is embedded to a predetermined thickness, so that the surface of the mixture is The gist of the method is to manufacture a gutter cover by uniformly leveling the mixture, fitting an upper mold therein, heating and pressurizing the mixture, and curing the mixture.

[Operation of the Invention] This invention is constructed as described above, and can be manufactured simultaneously by heating and pressurizing a reinforcing member having a plurality of through holes formed at predetermined intervals embedded in a mixture of powdered rubber and a binder. Therefore, the adhesive strength between the reinforcing member and the mixture can be increased, and the powder rubber composition is also in a uniform state, so that durability can be improved and production can be performed efficiently in a short period of time.

[Embodiments of the invention] Hereinafter, the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a partially cutaway plan view of a water-permeable gutter cover embodying the present invention, and FIG. 2 is a sectional view taken along the arrows in FIG. 1.
This water permeable gutter cover 11 is constructed by embedding a reinforcing member 13 such as an iron plate having a plurality of through holes 12 in a water permeable mixture 14 of powdered rubber and a binder.

This mixture 14 is integrally formed by filling the plurality of through holes 12 of the reinforcing member 13 during molding, and the surface 14a of the hardened mixture 14 is formed with grid-like grooves 15 in a pattern to create a design. It has sex.

The reinforcing member 13 may be made of any material, such as metal or concrete, as long as it has a reinforcing effect, and the shape may be a plate or a grid with a predetermined thickness as shown in FIG. The shape of the plurality of through holes 12 is not particularly limited, and may be round, square, hexagonal, or the like.

Note that the reinforcing member 13 using an iron plate can also have a grid-like form called a grating.

Next, a method for manufacturing the water permeable gutter cover 11 will be explained in FIGS. 4(a) to 4(a).
This will be explained with reference to FIG. 4(C).

First, as shown in FIG. 4(a), a lower mold 16 having a concave cross section
A reinforcing member 13 in which a plurality of through holes 12 coated with adhesive are formed at predetermined intervals is placed inside. Then, a predetermined amount of the mixture 14 of powdered rubber and binder is poured into the lower mold 16, and the plurality of through holes 12 of the reinforcing member 13 are
At the same time, the surface of the reinforcing member 130 is buried to a predetermined thickness.

Next, as shown in FIG. 4(b), the surface of the mixture 14 is leveled uniformly using a leveling rod (not shown) or the like.
As shown in FIG. 4(C), an upper mold 18 having a predetermined pattern 17 on the surface is fitted, and the mixture 14 is hardened by heating and pressurizing with a press or the like to compress the mixture 14. It manufactures.

As described above, the reinforcing member 13 in which a plurality of through holes 2 are formed at predetermined intervals is made of a mixture 14 of powdered rubber and a binder.
Since the reinforcing member 13 can be manufactured at the same time while being buried in
It is possible to increase the adhesive strength between the mixture 14 and the mixture 14, and also improve the durability, and it can be manufactured efficiently in a short period of time.

In addition, as shown in the cross-sectional view of FIG. 2, in order to embed the reinforcing member 13 between the mixture 14 (powdered rubber composition), a pin is driven into the lower die 6, and the reinforcing member 13 is supported by this pin. Just do it.

〔Effect of the invention〕

In the present invention, as described above, a reinforcing member in which a plurality of through holes are formed at predetermined intervals is placed in a lower mold, and in this lower mold,
Pour a predetermined amount of the mixture of powdered rubber and binder,
The mixture is filled into the plurality of through-holes in the reinforcing member, the surface of the reinforcing member is buried to a predetermined thickness, the surface of the mixture is evenly leveled, and then an upper mold is fitted and heated and pressurized. Since the gutter cover is manufactured by curing the mixture, the following excellent effects are achieved.

(a) In addition to increasing the adhesive strength between the mixture and the reinforcing member, if rubber is bonded to the top and bottom of the reinforcing plate,
Mechanical tethering can also be expected.

(b) Since the upper mold is pressurized by a press, by adjusting the amount of powdered rubber composition poured into the mold, the density of the powdered rubber can be changed at a constant thickness, and the water permeability coefficient can be adjusted as desired. It can be configured as a water-permeable gutter cover with

(C) Since the mixture of powdered rubber and binder is cured by applying pressure by pressing, the physical properties are strong, the curing time is quick, and processing costs can be reduced.

(d) Since it can be manufactured efficiently in a short time, productivity can be improved.

(e) It has an excellent walking feel and can also have soundproofing properties.
