Abstract

PURPOSE: A concrete block having a color which changes due to temperature is provided to detect the temperature of a road surface for itself and visually change a color due to the change of temperature. CONSTITUTION: A manufacturing process for a concrete block(1) having a color which changes due to temperature comprises the steps of: mixing an existing concrete(3) and mortar which is mixed with cement, water, and fine sand; adding thermochromic pigment(5) of about from 1 to 30 percent of total weight; filling a prepared mold with the mortar to maintain a whole shape; molding by evenly compacting through pressurization and vibration; drying and hardening; and making a complete block by removing the mold after curing.

Description

Concrete blocks that change color with temperature {Concrete Block}

The present invention relates to a method for manufacturing a concrete block that changes color according to temperature, and more particularly, in the manufacture of a block that changes color according to temperature using concrete, after demolding a molded block on a mold, a curing process is performed. The present invention relates to a method of manufacturing a concrete block in which the color is changed according to the temperature at which the Zion pigment is added to the Zion pigment so that the color can be changed according to the temperature during the demolding process of the block.

The present invention relates to various types of concrete blocks representing images by adding Zion pigments, which can change colors depending on temperature, so as to replace concrete blocks that do not change even in general spring, summer, autumn, winter four seasons or daily crossovers.

In general, sidewalk blocks are arranged in a row to face sidewalks such as sidewalks, sidewalks, residential complexes, plazas, parks, parking lots, etc. in consideration of urban aesthetics and ease of walking in urban planning. Blocks are used in various forms and purposes.

Recently, apartments, country houses, multi-purpose apartments and officetels have been constructed, and natural stone is used for marble, granite, and gravel on the side of the side of the living room, kitchen, toilet, and road to pursue well-being and luxury. There are a lot of cases that occur.

The natural stone can not be used unless the place of pursuit of high quality, because the manufacturing cost is high due to the high manufacturing cost

In addition, the existing concrete sidewalk blocks or blocks have a functional improvement, and there is a need to show the aesthetic conditions of the road and the temperature of the road surface.

By adding a new function to the concrete block, which is one of the existing pavement materials, a function that can change the visual color according to the temperature change while detecting the road surface temperature on its own was required.

The present invention has been made in view of the above problems, by using and using the concrete to produce a sidewalk block or concrete block, to form a Zion pigment composition layer, by applying the concrete mixed Zion pigment on the upper surface The goal is to provide a sidewalk block that can change color as the temperature changes around the day.

When using a concrete block that changes color according to the temperature according to the present invention, as a block for manufacturing a sidewalk block, and formed a Zion pigment layer thereon, the color naturally changes according to the road surface temperature even on the road surface temperature By providing the status to pedestrians and users, it is possible to give a dynamic color to the surroundings of urban buildings or parks.

Therefore, it is possible to provide a sight that naturally changes the color of the road according to rain, snow, and direct sunlight.

1 is an external perspective view of a concrete block that changes color according to a temperature according to the present invention;
2 is a side cross-sectional view of FIG.
Figure 3 is a side cross-sectional view of another Figure 1

It provides a concrete block that changes color according to the temperature according to the present invention.

It will be described in detail with reference to the accompanying drawings.

First, Figure 1 is an external perspective view of a concrete block that changes color according to the temperature according to the present invention,

2 is a side cross-sectional view of FIG.

The block of the present invention is a completed invention including the components of the Zion pigment (5) 1 to 20% mixed with the existing concrete (3).

Zion pigment (5) used in the concrete block (1) is changed in color according to the temperature according to the present invention after the color is changed when the temperature is changed, reversible Zion is restored to the changed display again when the temperature returns to the original It is a pigment (5) and has two or more kinds of display variations so that different colors can be displayed at the same temperature. That is, the Zion pigment 5, which can display different colors under the same temperature, has a characteristic that two or more colors can be changed.

Describe the manufacturing method so that these effects can occur,

Mortar mixed with cement, water, and fine sand in the prepared mold is added to the existing mortar process according to the existing concrete mixing process or regulation. A mortar process, a molding process of compacting and compacting through pressurization and vibration after the mortar process is finished, a curing process of drying and hardening after the molding process is finished, and removing the mold after the curing process is finished. It consists of a demolding process that makes a complete block.

And, in the mortar process, after applying the release oil to the surface of the mold, the mortar mixed with fine sand, cement and Zion pigment with water is applied with a spray or a brush to express various visual designs, as described above After the mortar process is completed, the mortar mixed with general sand, gravel and cement is filled with water into the mold, and after the mortar is filled, vibration and

Molding is performed using a press or the like applying a pressure. After the molding is finished, the mold is put into a curing chamber and cured, and then the mold is demolded to separate the molded block by mortar.

Thus, as shown in the drawing,

The concrete block (1), which changes color with temperature, is finished

1-30% of the total weight of the concrete block that changes color with temperature

It is a characteristic of Zion pigment (5).

In addition, the Zion Pigment 5 has a feature that includes two or more Zion Pigments 5 having different colors at the same temperature.

And Figure 3 is as shown in another cross-sectional view of Figure 1,

In order to save the Zion pigment (5) is also included in the scope of the present invention is a concrete block of the color is constructed and produced to be made of a conventional concrete block layer and a block layer to which Zion pigment (5) is added.

As such, the concrete block 1 in which the color of the two-layer structure changes can be completed as an application of the above-described manufacturing method.

Naturally, the Zion Pigment 5 may be applied to the range of the object of the present invention as long as it is a Zion Pigment 5 whose color changes in the air temperature range, that is, in the range of minus 20 to 40 degrees.

In other words, the present invention comprises a mortar process of mixing the mortar mixed with cement, water, and fine sand with a conventional concrete mixing process or regulation;

Filling process to maintain the overall shape by adding the mortar (5) of about 1 to 30% of the total weight to the prepared mold;

After the filling step is finished molding step of molding by pressing and vibration evenly;

Curing process to dry and harden after the forming step;

After the curing process is finished is a concrete block that changes color depending on the temperature is completed in the demoulding process to remove the mold to make a complete block,

As required,

Two or more Zion pigments used in concrete blocks that change color depending on the temperature may be referred to as concrete blocks that change color depending on the temperature of the feature having different colors at the same temperature.

1: concrete block with changing color
3: concrete 5: Zion pigment
