Abstract

PURPOSE:To obtain a water-permeable composite plate having excellent decorative effect and suitable for sidewalk tile, etc., at a low cost by mixing colored mineral particles and a resin, placing the obtained resin-concrete on one surface of a water-permeable concrete layer and integrating both layers. CONSTITUTION:A water-permeable composite plate is produced by mixing mineral particles such as colored natural stone, glass bead or colored porcelain piece with a resin such as epoxy resin, placing the obtained resin-concrete 2a, 2b, 2c, etc., on one surface of a water-permeable concrete layer 1 and integrating both layers by curing. Since the colored water-permeable resin-concrete layers 2a, 2b, 2c, etc., are formed on one surface of the water-permeable concrete layer 1 acting as a reinforcing layer, the thickness of the resin-concrete layers 2a, 2b, 2c, etc., can be decreased to reduce the production cost of the water-permeable composite plate.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water-permeable composite flat plate having a color pattern used for road pavement, etc., and a method for manufacturing the same.

[Prior Art] Conventionally, asphalt concrete or sidewalk slabs made from concrete factories have been used to pave sidewalks. Since these have no water permeability, water puddles during rain and becomes an obstacle to walking. In order to make the pavement water permeable, concrete slabs are laid down so that rainwater can permeate into the ground through their joints, and there are also permeable asphalt and water-permeable resin concrete pavements, but concrete slabs come in different colors. The pieces are laid out to form a pattern, so the design has a different perspective. Water-permeable asphalt pavement cannot be colored, and water-permeable resin concrete pavement can be colored, but it is extremely difficult and very expensive to construct it in a patterned manner.

A method for producing a water-permeable composite flat plate, which comprises integrally forming a resin concrete layer of a color different from the resin concrete, and in which at least one of the resin concrete layers is made water permeable.

[Effect]

In the water-permeable composite plate of the present invention, the water-permeable concrete layer is used as a reinforcing layer, and a colored water-permeable resin concrete layer is formed on one side of the water-permeable concrete layer, so the resin concrete layer can be formed thinly and manufactured at low cost. . In addition, since the concrete layer and the resin concrete layer are bonded using a resin such as epoxy resin used to bond the inorganic particles of the resin concrete, there is no need to use an adhesive between the layers, as in the case of bonding the layers with an adhesive. It does not impede water permeability. Since colored natural stones, glass beads, and ceramic pieces are used as aggregates for the resin concrete layer, it is possible to provide paving boards that are resistant to discoloration, peeling, and abrasion.

After forming a water-permeable resin concrete layer, if a concrete layer is poured on top of it and the resin concrete layer and cement concrete layer are bonded together with the cement of the concrete, the slurry in the concrete will be absorbed into the resin concrete layer. However, in the present invention, after forming the concrete layer, a resin concrete layer is formed on top of the concrete layer, so that the resin concrete layer is not contaminated by concrete slurry.

When configuring a color pattern using two or more types of resin concrete, one resin concrete that is adjacent to each other is cured before the other resin concrete is poured, so that color boundaries can be clearly formed without bleeding.

The mixing ratio of resin to mineral particles should be increased as the particle size becomes smaller, as the surface area per unit volume of particles becomes larger, and as the particle size becomes larger, the surface area per unit volume of particles becomes smaller, so it can be reduced. . Usually, the blending ratio of the resin in 100 parts by weight of the sebaceous concrete block may be 3 to 5 parts by weight.

〔Example〕

The square box-shaped formwork 3 shown in Figure 3 uses a saturated polyester board (to which epoxy resin does not adhere) for the bottom plate, the side frames are made of wood, and resin wax is applied as a mold release agent to the wood part. Inside, 1810 parts of crushed stone with a particle size of 15 wua,
These were mixed in a proportion of 87 parts by weight of cement and 280 parts by weight of water, and poured to a thickness of about 45 mm and hardened to form a water-permeable concrete layer 1. Next, cut out a piece of 24 mm thick plywood into the shape surrounded by the two diagonal curves in the square in Figure 1, apply resin wax as a mold release agent, and fit it into the formwork 3. is. On one side of the triangular parts on both sides of this plywood, 96 parts by weight of crushed light brown granite with a grain size of 5 mm and epoxy resin (2
Liquid Ebitsucuron 5129, hardening agent Laccamite WHO
51, hereinafter the same)), and into the triangular part on the other side, pour a mixture of 96 parts by weight of crushed dark brown granite with a grain size of 5 mm and 4 parts by weight of epoxy resin.2411! Smooth the surface to a uniform thickness of +11,
After curing with warm air at 0C for 5 hours, a light brown resin concrete layer 2a with water permeability and a dark brown resin concrete layer 2b with water permeability are integrated on top of the concrete layer 1. Formed by gluing. Next, the plywood was removed from the formwork 3, and a mixture of 96 parts by weight of crushed white granite with a grain size of 5 cm and 4 parts by weight of epoxy resin was poured into the remaining area to the same thickness as the resin concrete layers 2a and 2b. The white resin concrete layer 2C, which is poured and hardened in the same manner and has water permeability, is bonded together with the concrete layer 1 and the resin concrete layers 2ab and 2b to form the water permeable composite flat plate shown in Figs. 1 and 2. Had made.

This water-permeable composite flat plate is made by making a white resin concrete layer 2C in a separate formwork in advance, placing it on top of the concrete layer 1 made in the formwork 3, and applying dark brown resin on both sides. Concrete layer 2a and light brown resin concrete layer 2
Alternatively, the material b may be poured and hardened, and the dark brown resin concrete layer 2a and light brown resin concrete layer 2b, which are integrally adhered to the concrete layer 1, and the white resin concrete layer 2c may be integrally adhered. .

For example, when forming black polka dots on a white background, when the area of the polka dots is small compared to the overall area, the resin concrete layer that takes over the polka dots is
It does not necessarily have to be water permeable.

Also, the entire surface of the resin concrete layer is concrete layer 1 in color.
By forming a polygonal flat plate so as to cover the sides, it is possible to provide an unprecedented product such as a garden stepping stone. With such products, it is also possible to create elaborate designs by providing unevenness on the surface. It is also possible to cast resin concrete using a thin separator according to the color pattern and remove it before hardening, allowing both to harden at the same time.

〔Effect of the invention〕

According to the present invention, water-permeable sidewalk boards with unprecedented decorativeness and stepping stones for gardens and parks can be provided at low cost.
