Abstract

PURPOSE:To improve drainage, and to attain the safety of a walk by laying a block, in which a plate, which is manufactured by coupling natural stone with a resin and has water permeability, and a concrete slab, which has a percolation hole and to a side face of which an irregular section is formed, are shaped integrally, onto a road surface. CONSTITUTION:Natural stone and an epoxy resin are introduced into a mold and cured and bonded, thus forming a plate 1 having water permeability. Forms are mounted around the plate 1, ready-mixed concrete is poured into the forms, and a plurality of holes 3 are shaped to a slab 2 in which the plate 1 of natural stone and concrete are unified. The blocks 2 are laid continuously onto a road so that protruding sections 4 and recessed sections 5 formed to the blocks 2 are engaged mutually. Rainwater is infiltrated under the ground through the through-holes of the plates 1 and the holes 3 of the concrete slabs 2. Accordingly, sliding due to a sump and rainwater is removed, and a danger is prevented while the washing finish of stucco and joint treatment are unnecessitated, thus simplifying manufacturing and execution processes.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a natural stone permeable flat plate block.

[Prior art and its problems] Flat blocks are widely used for paving sidewalks, plazas, etc.

However, in conventional flat plate blowing, devises such as washing are used to create a natural feel, and the manufacturing process is complicated.

Further, since conventional flat blocks do not have water permeability, they have the problem that rainwater accumulates and forms puddles, which poses a risk of slipping and falling due to the puddles or rainwater.

Furthermore, since the conventional method of construction was to join the joints, weeds and the like could grow in the joints, spoiling the aesthetics.
In addition, the weeds and other objects would lift the unit, creating a hole at the bottom of the unit, and the water that had accumulated in the hole would be pushed by the force from above and fly away.

Furthermore, since the conventional flat block construction method involves joining individual products together, there is a problem in that joints always require joint treatment.

The present invention solves the above-mentioned problems, and allows a natural feel to be obtained without any efforts such as washing out. Rainwater that falls on the pavement immediately permeates underground and does not form puddles. It eliminates slipping, allowing safe walking, distributes the force from the top, prevents the unit from shaking, and maintains its aesthetic appearance by preventing weeds from growing at the joints. This natural stone water permeability eliminates the need for joint treatment, and prevents the harmful effects of weeds and other objects lifting up, creating holes at the bottom of the unit, and water that collects in these holes being pushed by force from above and flying away. The purpose is to provide a flat plate block.

[Means for Solving the Problems 1] In order to solve the above problems and further achieve the object of the invention, the natural stone permeable flat plate block according to the present invention is characterized by having the following structure. That is, it is a block in which aggregate is bonded with resin to form a flat plate of water-permeable natural stone, and a concrete flat plate is integrally formed on the lower surface of the natural stone flat plate, and the concrete flat plate has a It is characterized in that a plurality of holes are provided, a convex part and a concave part are formed on the side surface of the blow 2, and the convex part and the concave part are formed so as to mesh with each other.

[Example] DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below using embodiments shown in the drawings.

FIG. 1 is a perspective view of a first embodiment of a flat plate block having natural stone water permeability according to the present invention, FIG. 2 is a perspective view of the second embodiment, and FIG. 3 is a side view showing a joined state. Here, 1 is a natural stone flat plate, 2 is a concrete flat plate, 3 is a hole, 4 is a convex part, and 5 is a concave part.

The natural stone slab 1 is formed by bonding aggregate with a water-permeable resin. Various types of aggregate can be used for the aggregate, but using natural stone gives the best natural look. Examples of natural stones include naturally collected pebbles, polished pebbles, and crushed natural stones. Furthermore, various resins can be used as the resin, but among them, flexible epoxy resin is particularly suitable because of its durability. In order to bond the aggregate with a resin in a water-permeable state, for example, the following procedure is performed. Two parts of a two-component flexible epoxy resin separated into a base resin and a curing agent are thoroughly mixed. Add approximately 30 times more natural stone than this resin and mix thoroughly. This mixture of natural stone and resin is put into a predetermined mold, the resin is cured, and then taken out.In the above formulation, the resin is only used to connect the natural stones, so the natural stone and the natural stone are separated. are joined with resin to form a flat plate, but gaps remain between the natural stones. Therefore, water can pass through this remaining gap, and the natural stone flat plate 1 formed as described above has water permeability.

A concrete flat plate 2 is integrally formed on the lower surface of the natural stone flat plate 1 to form a block. This block is formed by providing a formwork around a natural stone slab l, pouring fresh concrete into the formwork, and then removing the formwork after the concrete has hardened. In this way, the concrete flat plate 2 can be integrally formed on the lower surface of the natural stone flat plate 1. Since the natural stone flat plate l has a water-permeable gap as described above, the concrete bites into the gap, and the natural stone flat plate l and the concrete flat plate 2 are firmly integrated.

When forming a block by integrally forming a concrete flat plate 2 on the bottom surface of a natural stone flat plate l, the concrete flat plate 2
A plurality of holes 3 are formed in a concrete flat plate 2 by shaping a mold so that a plurality of holes 3 are formed in the concrete plate 2. The plurality of holes 3 allow water that has passed through the natural stone flat plate 1 to permeate underground.

Further, when forming the block, a protrusion 4 and a recess 5 are formed on the side surface of the block, and the protrusion 4 and the recess 5 are formed to mesh with each other.

By forming in this way, the convex portion 4 and the concave portion 5 can be constructed so as to be engaged with each other, as shown in FIG. 3, which is a side view showing a joined state.

By interlocking the convex portion 4 and the concave portion 5 with each other in this way, the force from the upper part can be dispersed, and the swinging of the single body can be prevented. Here, shaking refers to the fact that the car body becomes uneven one by one after construction.

In addition, since the convex part 4 and the concave part 5 are engaged with each other, the appearance can be maintained without weeds growing at the joint.Furthermore, weeds can lift the unit and create a hole at the bottom of the unit. It also prevents the harmful effects of water that has accumulated in the pipes being pushed out by force from above and flying away, and there is no need for joint treatment.

[Effects of the Invention] Since the natural stone water-permeable flat plate block according to the present invention is configured as described above, it has the following effects.

Firstly, in conventional flat blocks, measures such as washing have been used to create a natural feel, but the flat blocks according to the present invention are made of natural stone, so no measures such as washing have been applied. However, it has the effect of providing a natural feel.

Second, conventional flat blocks collect rainwater and form puddles, which poses a risk of slipping and falling due to puddles or rainwater. On the other hand, the flat plate block according to the present invention has the effect that rainwater that falls on the pavement immediately permeates underground, so no puddles are formed, thus eliminating puddles and slipping caused by rainwater and allowing safe walking. .

Third, because the conventional flat block construction method is a construction method that involves joining individual products together, there is no countermeasure for the swinging phenomenon that occurs due to the force from above. Since it is a construction method that is made by fitting together,
Weeds and the like grow in the garnish area, spoiling the aesthetics, and the weeds lift the unit up, creating a hole at the bottom of the unit, and the water that accumulates in the hole is pushed by the force from above and flies away. There were negative effects.

On the other hand, the flat plate block according to the present invention has a convex part and a concave part on the side surface and is formed so as to mesh with each other, so that the force from the upper part is dispersed by the meshed part,
This has the effect of not causing any damage to the single unit. It also has the effect of preventing weeds from growing in the joints and maintaining the aesthetic appearance. Furthermore, it has the effect of preventing the harmful effects of weeds and the like lifting the unit, creating a hole at the bottom of the unit, and causing water accumulated in the hole to be pushed by force from above and blown away.

Fourth, the conventional flat block construction method is a construction method that involves joining individual products together, so joints always require joint treatment, but the flat block according to the present invention has convex parts and concave parts on the sides. However, since they are formed so as to interlock with each other, they have the advantage that no joint treatment is required.

Since the water-permeable flat plate block according to the present invention has the above-mentioned effects, it can be usefully used for paving a wide variety of places such as sidewalks and plazas.
