Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing a civil engineering and construction material in which a concrete product is combined with FRP decoration.

[Conventional technology]

Most of the conventional concrete products, stone, tiles, brick coatings, etc. are the cause of defects such as fading of the color of the frame at joints and joints. Since the progress of construction is measured by hand, the weight and area of the product have been increased as much as necessary.

Nevertheless, it has been considered a certain method in the long history of the East Coast. Therefore, it is easy for 2 tsul to occur at the joints and joints of buildings, etc., and turbid water on the buttocks can cause severe damage to IJs objects.
Water leaks in cold regions sometimes have a serious effect on iron parts, wood, etc. On that point, the present invention modifies a part of the conventional standard with FRP, commercializes a simple joint without joints, and repairs the joint after construction on site, so it can be used regardless of the size of the area. , it became possible to create a one-piece product with no joints or joints. On the other hand, among architectural decorative products, most of them, excluding those related to handrails and fences, are for the sole purpose of appreciation, and there are many products that have been developed that serve two completely different roles. Not yet.

[Problem that the invention seeks to solve]

Recently, some concrete slabs have been made with slight convexities on the V-shaped contours, and the colors have been toned with pigments. The cost of these decorations is considerably lower than that of other ornaments.

If you were to engrave the 9th part, which raises the grade, by adding curved stones and dots about the thickness of a chopstick, you would only add a light vIs to this, and the corners and convex parts would be simply orchid. Furthermore, it was impossible to commercialize concrete decorations because they were easily contaminated by sewage, so the places where they could be used were limited and the range of use was narrow.

[Means to solve the problem]

The purpose of this invention is to solve these problems with conventional concrete products, and the manufacturing method according to the invention will be explained in detail below, step by step.

■Explanation for making a female mold Using two Enbi boards with a thickness of 8IIE or more and a width of 30mm (Jin, length 500mm), separate these two boards from the core, Draw a rectangle of my friend,
Next, draw a 40011x400 dragon square on tracing paper, draw a simple and precise pattern inside it,
Draw a straight line #I at the center to bisect it into two rectangles.

Stir thoroughly. Store this in a place out of sunlight for about half a day. After that time, add 0.5 g of hardening agent and carefully stir. Step 9: Stir and pour into the two female molds shown in Figure 1 a and b. The thickness of the mixed liquid is 0.
Within 5 to 131I, adjust it fairly uniformly with a 500-width joint brush. It will gel in about 25 minutes at room temperature 23°C, so leave it for that time. In the meantime, wash the dirty brushes and containers with acetone, then cut two pieces of glass fiber into rectangles with a width of 200w and a length of 4001m. Put 200 g of polyester resin into the container again, add Ig of curing agent, and stir carefully.

Using a tipped brush, apply it thoroughly onto the gelled female mold, place the cut mat 7 on top of it, and smooth it with a brush as you apply it. On top of that, pour the remaining resin evenly into the two female molds shown in Figure M1, a and b, and the matt rzI that comes out of the frame! Place it within the frame b.

Next, the width of the building block shown in FIG. 38 is 190n.

Gently place the 390m+ length and 100g thickness on the bottom two sides of the embroidery frame shown in Figure 1, 6, accurately.
