Abstract

PURPOSE:To efficiently produce a decorative block in which seed stone becoming decorative material is buried only on the single face by spreading seed stone on the surface before cement slurry in a formwork is not hardened and reintroducing cement slurry on the upper part thereof and hardening it and thereafter dividing cement from the spread face of seed stone. CONSTITUTION:Cement, sand and water are mixed and the obtained cement slurry is introduced into a metallic formwork which is worked so as to hold a cavity part to the inside. Before this cement slurry is hardened, seed stones 1 obtained by grinding marble becoming decorative material are uniformly spread on the surface. Thereafter the other formwork having the same inner shape as this formwork is placed and furthermore cement slurry is introduced and then aged and hardened. When the upper and lower formworks are removed after aging and hardening and cement slurry is divided into two bodies from the face wherein seed stones are spread, a decorative block is obtained in which the decorative material is buried only in the single face.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a decorative block in which a seed stone serving as a decorative material is embedded only on one surface of a concrete block.

[Conventional technology] Conventionally, decorative blocks with seed stones buried therein that serve as decorative materials only on the surface are made by pouring cement slurry into a mold of the desired shape, scattering the seed stones on the surface, curing and hardening, and then molding. The frames were removed and decorative blocks were manufactured one by one.

[Problems to be Solved by the Invention] However, in this method, the decorative blocks were manufactured one by one, resulting in poor efficiency and high cost.

[Means for solving the problem] This invention improves the above-mentioned problems by injecting cement slurry into the formwork and applying seed stones to the surface of the cement slurry before the cement slurry hardens. Then, while placing another formwork on top of the above formwork, cement slurry was injected into the upper formwork once, and after curing and hardening, the upper and lower two formworks were removed. The present invention, which relates to a method of manufacturing a decorative block that is divided into two pieces from the seed stone scattering surface, will be described in further detail below.

First, cement was placed inside a formwork made using plywood or metal.
A cement slurry consisting of water and sand is injected, and seed stones 1 serving as a decorative material are sprinkled on the surface of the cement slurry while the cement slurry is not hardened.

The shape of the formwork used in the present invention may be a solid shape as shown in Figure 1(a), or a normal block-like structure with a cavity inside as shown in Figure 1(b). Just make a mold according to the block.

The seed stone may be one made by crushing igneous rock, metamorphic rock, or pre-aquatic rock such as granite or marble W, or one made by crushing terrazzo or artificial stone again.

Next, another formwork is placed and fixed on the upper part of the formwork after the seed stone 1 is removed, and then cement slurry is injected into this upper formwork again.

After curing and hardening, remove the upper formwork,
Finally, divide it from the side where Seed Stone 1 was scattered to obtain two individual decorative blocks.

The formwork used in this invention has a height of approximately one individual decorative block as described above, and after pouring cement slurry and seed stone into the formwork, a formwork similar to the lower formwork is placed on top of the formwork. You may place the cement slurry again into the upper formwork after placing it, but it is also possible to prepare a formwork whose height is approximately the same as two pieces of decorative blocks in advance, and then Cement slurry, seed stone, and cement slurry may be injected into the formwork in this order and allowed to cure and harden.

[Function] In this invention, in the formwork into which the cement slurry has been poured, stones are sprinkled on the surface of the cement slurry while the cement slurry is not hardened, and the cement slurry is again poured on top of the cement slurry and hardened. After that, the seed stone is divided from the dispersion side in order to efficiently manufacture a decorative block in which the seed stone that will serve as a decorative material is embedded only on one side.

[Example] First, a cement slurry containing cement, sand, and water is injected into a metal formwork that has been processed to have a cavity inside, and before the cement slurry hardens, it becomes a decorative material. Seed stone 1 made from crushed marble was uniformly scattered on the surface.

Thereafter, another formwork having the same internal shape as the above-mentioned formwork was placed, and cement slurry was further injected, followed by curing and hardening.

After curing and curing, remove the upper formwork and divide into two pieces from the side on which Seed Stone 1 was sprinkled, and make a decorative block with decorative material embedded only on one side as shown in Figure 1 (:l). .

[Effect] In the present invention, the seed stone serving as the decorative material is not only buried on one side, but also two individual decorative blocks are manufactured at the same time.
Since it only needs to be divided at the end, it is very efficient and economical.

Claims (1)

[Claims] 1. Pour cement slurry into the formwork, sprinkle seed stones on the surface of the cement slurry before it hardens, place another formwork on top of the formwork, and then This method for producing a decorative block is characterized in that cement slurry is again injected into the upper formwork, cured and hardened, and then the upper and lower two formworks are removed and the blocks are divided into two pieces from the seed stone scattering surface.
