Abstract

PROBLEM TO BE SOLVED: To resolve the problem with construction of walls or fences from piled up concrete blocks that the walls or fences thus formed are too heavy leading to poor productivity, by using resin blocks for lighter weight and easier handling and to provide the feeling of stone and enhance fire resistance by providing pumice or the like on the surface of a wall or fence. SOLUTION: Pumice, quartz sand and other minerals are pulverized and a resin and clay or cement or the like are admixed and applied to a mold as a binder. A raw resin comprising unsaturated polyester resin blended with calcium carbonate is blended with an inorganic pigment and reinforced with glass fibers and is applied to the block-shaped mold by hand lay-up.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone-like lightweight resin block, a fence and a pillar used for construction or civil engineering.

[0002]

2. Description of the Related Art Conventionally, a stack of building blocks (hollow concrete blocks) has been used for a simple building wall or a boundary block wall of a site such as an adjacent house.

[0003] The above-mentioned building block has a well-known shape as shown in FIG. 3, and a filler (such as gravel) and water are added to cement and mixed well to form a state like wet soil. The material is molded by a block machine using both pressure and vibration, and after demolding, it is usually hardened for a period of about ten hours to harden the cement. This manufacturing method is widely used as a general manufacturing method. In addition,
3, reference numeral 9 denotes a hollow portion of the block 8, and reference numeral 10 denotes a rib of the block 8.

[0004] A wall, a fence or the like shown in Fig. 4 using the building block is generally constructed in the following procedure. A horizontal base 11 is made of concrete or the like on the ground. : This foundation 1
The building blocks 8 are stacked one by one on the top 1, and the joints are bonded with mortar to prepare joints 12. : When the strength is required, the hollow portion 9 of the building block 8 is required.
A PC steel rod is erected and filled with mortar. :Also,
When a landscape is required, makeup is applied to the surface of the built wall or fence with mortar 13 or the like.

[0005]

Since the above-mentioned building block 8 is made of concrete, the weight per block is 6.5 kg to 17 kg depending on the size.
Workers are extremely burdened when transporting or constructing fences. In addition, when stacking building blocks 8 in the construction of fences, etc., it is necessary to fill the mortar as an adhesive between the blocks, remove excess mortar for finishing and adjust the appearance of joints, and it takes time and labor. It takes. Furthermore, when a landscape is required, the mortar coating is performed after the building blocks 8 are stacked, so that more time and labor are required. Further, the resin block is lightweight, but lacks a stone feel, and does not consider fire resistance.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a stone-like lightweight resin block which is lightweight, easy to handle, has fire resistance on the surface, and is excellent in landscape. To provide.

[0007]

In order to achieve the above object, a stone-like lightweight resin block according to the present invention is provided with ribs integrally between long side walls.

Further, the stone-like lightweight resin block fence according to the present invention is provided with a stone-like lightweight resin block having ribs integrally formed between long side walls, and a reinforcing bar is arranged in a hollow portion. It is made by filling mortar.

[0009]

The block according to the present invention is manufactured by arranging pumice, silica sand and other minerals on the surface thereof and reinforcing it with resin. The block can be made much lighter than a conventional concrete block, and can be made of concrete. Is not brittle, handling is easy, and stacking work when constructing walls, walls, etc. is facilitated. In addition, by mixing pigments of various colors with the raw material resin, a colorful stone-like lightweight resin block having an arbitrary color can be obtained. Furthermore, by arranging pumice, silica sand and other minerals on the surface, the fire resistance is remarkably increased as compared with the conventional resin block, and the stone has a texture and the landscape can be enhanced.

In the fence according to the present invention, in the case of a fence in which a stone-like lightweight resin block is erected, reinforcement is provided in the hollow portion and mortar is filled to increase the strength of the fence. be able to.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. [Example 1] Pumice, silica sand and other minerals were powdered, mixed with resin, clay, or cement as a binder, applied to a mold, and mixed with an unsaturated polyester resin and calcium carbonate in a raw material resin. An inorganic pigment is compounded as a pigment and reinforced with glass fiber, which is hand laid up in a block-shaped mold. Accordingly, the dimensions shown in FIG. 1 are 1020 mm on the long side (1), 160 mm on the short side (S), 5 mm in thickness, and made of a stone-like lightweight resin having two 2 mm-thick ribs (r) inside. Block 1 was manufactured.

The above-mentioned stone-like lightweight resin block 1 comprises:
The weight per unit was 3.9 kg, which was about 24 to 30% of that of the conventional concrete block, and was light. Therefore, the burden is reduced not only for carrying during transport, but also for stacking when constructing walls and walls, etc., and the workability is greatly improved.
In addition, the surface of the block is natural stone, tile, brick, and has excellent landscape. Further, the fire resistance was significantly higher than that of the conventional resin block.

Embodiment 2 FIG. 2 shows a fence using a stone-like lightweight resin block. In this fence 3, a foundation 4 is laid on the ground, and the stone-like lightweight resin blocks 1 shown in the first embodiment are erected in two rows and four stages on the ground. A plastic adhesive is applied to the joining surface of the resin and joined, while a stone-like resin-made decorative plate 5 of the same color as the block 1 is provided on both left and right ends, and a stone-like resin-made roofing material of the same color as the block 1 is provided on the upper end. No. 6 is constituted by bonding with a plastic adhesive. In addition to the bonding of the adhesive, a bonding method using bolts and screws can be used. In FIG. 2, reference numeral 7 denotes a joint of the joint surface.

The fence 3 has a good appearance because the construction period and the labor of the construction are greatly reduced, and the surface is colored with pumice, silica sand or other minerals.

The wall 3 can function as the wall 3 even if only the adhesive is bonded as described above. However, in order to further increase the strength, it is necessary to fill the hollow portion 2 with mortar. Hollow part 2 to increase strength and strength
It is good to arrange rebar.

[0016]

As described above, the stone-like lightweight resin block according to the present invention is lightweight,
It is easy to handle during transportation and construction, and bonding is done with adhesive or
The work can be shortened by using bolts and screws. In addition, the fences and walls that have been constructed are colored with pumice, silica sand, or other minerals on the surface, so they have a good appearance and can easily obtain higher fire resistance than conventional resin blocks. .
