Abstract

PURPOSE:To provide a forming method of color concrete water collecting cover used for various side gutter blocks. CONSTITUTION:A primary formed article A-1 is formed of glass fiber-containing reinforced concrete by no-delay demolding and, by employing a pallet 15, onto which color mortar is built up, decorative surface is formed so as to form a color water collecting cover. Since glass fiber-containing concrete is used, the integral forming of the concrete and the decorative layer becomes stronger, resulting in making no-delay demolding possible.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of molding a water collecting lid used for various gutter blocks.

2. Description of the Related Art Recently, as part of revitalizing the town, it has been actively practiced to improve the environment and beautify, and examples of this include tiles of various colors and shapes on sidewalks, streets, parks, plazas, etc. It is done by laying it down and making the landscape beautiful.

However, even in such a beautifully maintained place, the drainage gutter constructed here uses the conventional gutter block of the old type, so that the gutter of this gutter is used. Only the part remains in a concrete color, and it looks like it stands out from the surrounding landscape, and it does not match the environment. For this reason, recently, there is a tendency to use color mortar on the surface or to use a decorative gutter block in which tiles or the like are laid. However, the water collecting lid used for this gutter block is unsightly because a conventional metallic grating lid is used. Therefore, it is considered to use a water collecting lid with a colored mortar finish or tiles on the lid of the gutter block having this decorative surface. However, since the water collecting lid has many through holes for collecting water. It was difficult to maintain the strength, and the molding means was complicated.

SUMMARY OF THE INVENTION The present invention is a method of molding a water collecting lid used for a gutter block having such a decorative surface, even if a large number of water collecting through holes are provided. By using a cloth filter for dehydration and reinforced concrete mixed with glass fiber, it is possible to perform the procedure well and maintain sufficient strength. Since it became possible, it is not necessary to prepare many formwork,
Multiple molding is possible.

In general, when a concrete block is formed by immediate demolding, slump-free concrete is used, and it is compacted by vibration and press by a block machine. If fiber-containing concrete is used and the core for forming a large number of water collection holes is complicated and the concrete is a slump-free kneading machine, ensure that concrete is filled between the complicated cores. It is difficult to use and some concrete must be used. For this reason, a cloth filter is provided on the core having a through hole and the side wall of the mold, and the concrete is compacted by the press and the moisture is squeezed out to immediately succeed in the mold release, and also when the surface decorative layer is formed. Even if a glass fiber-containing makeup mortar is formed on the surface of the lid that has been aged and cured, the glass fiber is mixed in the concrete and the surface is rough, so it fits well with the makeup mortar and solidifies. The decorative layer on the surface does not peel off even after the treatment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of molding a color water collecting lid according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a side groove block B having a decorative surface using the color water collecting lid, and C is the Beams for reinforcing the gutter block, D is an opening. The collar water collecting lid A formed by the present invention is fitted into the opening D. Since the surface of the gutter block B shown in the figure is formed by a tile pattern, the surface of the color water collecting lid A to be fitted needs to have the same tile pattern, but the invention is not limited to this, and it is not limited to this. Of course, it may be colored or stone-clad, and it will be a decorative surface suitable for the surrounding landscape. 2 is a plan view of a color water collecting lid A formed by the method of the present invention, and FIG.
It is a -X sectional view. In the figure, reference numeral (1) is a tile pattern formed on the surface, (2) is a joint for forming the tile pattern, and (3) is a water collecting hole, which is provided in large numbers (12 in the figure). Further, (4) shows a rib for reinforcement, and (5) shows a side of the lid A. The molding method of the present invention will be described step by step with reference to FIG. 4 and subsequent figures. In FIG. 4, (10) is a mold, and the mold has a trapezoidal cross section and is installed with the surface having a large opening area facing upward. To do.
Reference numeral (11) denotes a receiving pallet that comes into contact with the bottom surface of the mold (10), on which rubber packing (not shown) for preventing rattling noise is laid. (12) is a core for molding the water collecting hole (3) and the rib (4). The mold (10) is constructed in this way, and concrete is poured from above as shown by arrow F. The concrete used here is a reinforced concrete containing glass fibers, and a soft-mixed concrete containing an appropriate water content is used. Further, through holes (14) for dehydration are provided on the side surfaces of the mold (10) and the core (12) of the present invention, and further, a cloth filter is attached, and as shown in FIG. When added, the water W in the concrete passes through the filter (13) and is dehydrated from the core and the side frame of the through hole (14). (P-1) in the drawing indicates a press board. In the present invention, even if soft-mixed concrete is used, water in the concrete is dehydrated by the press, and since the glass fiber is mixed, the press P enables immediate demolding. Therefore, as shown in FIG. 6, a molded product (A-1)
And the receiving pallet (11) are demolded downward and moved to the curing step. After the curing and solidification, the molded product (A-1) is inverted and placed on the pallet (15) on which the color mortar M is put. This pallet (15) is a dish-shaped one having a weir-shaped protrusion (16) on the periphery thereof, and a protrusion (17) for forming a water collecting hole is provided at an appropriate position in the center, which is a color to be used. Mortar M is mixed with glass fiber. The molded product (A-1) is placed on the pallet (15) thus formed and transferred to the curing chamber for solidification. After curing and solidifying, the pallet (15) is removed from the mold to obtain the lid A having a decorative surface. Although not shown, in the case of forming a tile pattern on the surface as shown in FIG.
5) A tile pattern is formed by arranging tiles on top of each other, or by providing a ridge for forming a grid-like joint that matches the tile, and other patterns can be similarly expressed. Even when the color mortar M is attached to the solidified molded article (A-1) having no decorative surface in this manner, the surface of the molded article (A-1) because the glass fiber is mixed in the concrete in the present invention. The glass fiber appears on the surface to form a rough surface, and since the glass fiber is mixed in the color mortar M as well, the lid A, which is well integrated with the color mortar M, is strong against impact and has a color mortar. No peeling or damage of layers.

INDUSTRIAL APPLICABILITY According to the present invention, since the concrete containing glass fiber is used, the lid A itself has strength and can cope with load and impact even if many through holes are formed like a water collecting lid. In addition, it has a molding advantage that a large number of molds and cores are not prepared in order to enable immediate demolding in molding, and it also uses color mortar only on the decorative surface. Material costs are low. Further, even when the color mortar layer is formed on the solidified molded product (A-1), the glass fiber is mixed therein, so that it has a good familiarity and is free from peeling and damage, and on the receiving pallet (11). By laying the rubber packing on the inner wall, rattling and noise can be prevented, and there is an effect that no metallic noise is generated when the vehicle passes, unlike the conventional grating lid.
