Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an environmentally friendly adhesive coated with Table 1m material.

"Environmental Pro" or "Rito" refers to a building that has an appearance that is compatible with the natural landscape or natural environment. It is usually a concrete bronc with exposed surface material made of natural materials. Blocks for seawalls and other civil engineering projects with natural gravel or crushed stone embossed on the surface are known as a type of environmental protection block.

Such professional materials are manufactured by the washing method.

The washing-out method is a method in which natural gravel, etc. is placed on the surface layer of concrete, and the surface layer is washed with water before it completely hardens, and by washing away some of the concrete I, the natural gravel, etc. is brought to the surface. It is. In this case, it is also known to place lime, cleanser, etc. in advance on the area to be washed in order to facilitate washing.

This conventional washing method consists of (1) applying lime or cleanser to the area to be washed in advance;
It would be a waste of time to install something mixed with water, but it takes time and effort to mix it with water and install it.

(2) It is difficult to cleanly remove lime, cleanser, etc. from concrete when washed with water, and it is difficult to remove lime, cleanser, etc. from the corners, so it takes a long time to remove it, and it is difficult to obtain a beautiful product.

(3) Lime, cleansers, etc. are disposable.

There were drawbacks such as.

In the production of environmental blocks, which have recently been attracting attention, the present invention has carried out various researches in order to solve problems such as product quality and production time in this type of block production using conventional cleaning θ. This product was completed as a result of the research, and we discovered the excellent properties of 1 ash and decided to utilize this property.We developed a new manufacturing method that eliminated the drawbacks noted above. The purpose is to provide

The present invention relates to a method for manufacturing professional lumber in which materials suitable for the place of use, such as natural gravel, natural stone, crushed stone, etc., are exposed on the surface depending on the environment of the place of use.

The present invention will be explained with reference to the following drawings. FIG. 1 is a sectional view of a block formwork to which the method of the present invention is applied.

First, place the formwork bottom plate 1 horizontally, apply a release agent etc. to the bottom plate and the side formwork 2, and set the side formwork 2 around the four circumferences of the bottom plate 1.Next, 1 ash 3 is placed on the formwork bottom plate 2 Spread it to a thickness of ~3 cm. Shell ash is produced by burning clams, and is a fine powder particle that has no hygroscopicity and has extremely good water resistance properties. 1. Ash can be used repeatedly. Therefore, the used ash can be repeatedly reused in this method.1 Ash can be used as it is in a dry state, and even if it is in a tangled form, special kneading or other operations are not required. Therefore, compared to the conventional method using lime or cleanser, the labor required for construction can be significantly reduced.

Next, lay out the surface material 4 of Teppeishi Nato and Shoryo with 1 ash of 1 ash, with the surface facing the F side (14 in contact with the shell ash). Table 1
The nJ material is embedded during plate placement by approximately 35 to 35 mm of the leveling thickness of the plate. Next, a thin layer of mortar is applied, and then cores 5 and the like are attached to the side formwork 2, and concrete 6 is installed. Concrete pouring, vibrator compaction, concrete curing, etc. are no different from other block manufacturing methods.

After the prescribed curing period is completed, the product is removed from the mold. In the demolded state, the 11 ashes form 48 ash on the surface of the block in the fStS shape.
I'm in 1st place.

Next, when the 1 ash is washed off with a shower or the like, the 1 ash falls off very easily and can be removed together with water. FIG. 2 is a perspective view of the outer shape of the burofuku manufactured in this manner. The method of the present invention has the following effects when manufacturing environmental blocks.

■Since shell ash is used, cleaning is easy and complete, the cleaning material can be used repeatedly, and there is no need for kneading, which simplifies the manufacturing process and saves labor.

・2) It is possible to easily produce a block with a beautiful surface.
