Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing corner decorative blocks by pouring colored concrete, and is a method that is extremely easy to manufacture.

Instead of using conventional concrete blocks, attempts have been made to embed tiles into the surface of concrete plates to achieve a beautiful surface finish (Utility Model Publication No. 50-5903).
), it is very time-consuming to lay the tiles one by one in the formwork without any disturbance during concrete molding, and the manufactured concrete plate with tiles requires a lot of effort to connect the concrete plate and each tile. If this is not done reliably, there is a risk of individual tiles peeling off, etc. Also, in the case of exterior use, tiles are likely to chip or crack, and concrete plates with tiles are used due to the cost. This was expensive.

Therefore, the inventor developed a unique decorative concrete block that is much cheaper, easier to manufacture, and has superior strength compared to the concrete plate with tiles, but this decorative concrete block is colored. Because a hollow or solid concrete block is connected and fixed to a plate-shaped decorative block made of concrete, it is difficult to use for masonry at corners due to its thickness, so it is not suitable for this purpose. A corner shaped concrete block is needed, and the present invention makes it possible to easily manufacture a block suitable for masonry at the corner and suitable for use in combination with the new decorative concrete block described above.

That is, in the method of the present invention, a space on the back side of the decorative block is placed inside a container-shaped form body formed of a synthetic resin foam so as to have an uneven portion forming the masonry pattern of the corner decorative blocks. An auxiliary formwork made of synthetic resin foam is inserted and fixed in place, and colored concrete is poured into the space created between the formwork main body and the auxiliary formwork, and after hardening, the formwork main body and auxiliary formwork are covered with nichrome. It is characterized in that the decorative block with the masonry pattern is taken out by cutting it from an appropriate position by means such as cutting.

Next, embodiments of the present invention will be illustrated below with reference to the drawings.

10 is a container-shaped formwork body, and 20 is an auxiliary formwork, both of which are made of synthetic resin foam such as polystyrene foam.

The inside of the form body 10 has uneven portions 12.11 for forming uneven portions 31.32 of the masonry pattern of corner decorative blocks 30, 30'.

The auxiliary formwork 20 has one or more, and is used to form the back side space 33 of the decorative block 30, 30'. They are fitted together and connected and fixed by adhesive, fusion, or other means.

Reference numeral 24 denotes a cut-out portion, and 14 denotes a recess formed as necessary in the form body 10, and is used to form a protrusion 34 for dimension adjustment at one end of the upper and lower ends of the masonry side of the decorative block. .

This upper ridged protrusion 34 can be used to finely adjust the masonry dimensions by cutting off a necessary amount during masonry construction of the decorative blocks 300.

The internal mold surface of the formwork body 10 has a formwork shape corresponding to the shape of the corner decorative block 30, and has uneven portions 12.11 forming the masonry pattern of the formwork body 10.
When manufacturing a rectangular decorative block 30 with square sides (see FIGS. 1 and 5), an arc-shaped decorative block 30 with an arc-shaped side
' (see Figures 7 to 10).

An example of a method for manufacturing a corner decorative block using the formwork with the above configuration is as follows: In the space C created between the formwork main body 10 and the auxiliary formwork 20, simply colored concrete or glass fiber is poured. As reinforced colored concrete, add 10 parts of white cement to 2 parts of sand to a length of 15
Pour a mixture of wn8 degree glass fiber and some pigment, and after solidifying, cut the formwork body 10 and auxiliary formwork 20 at appropriate locations using a nichrome cut or other means to remove the corner decorative blocks 30. It is something.

A new formwork main body 10 and auxiliary formwork 20 will be added during the next production.
You can use

Note that instead of the glass fibers mentioned above, other fibers (for example, nylon fibers) may be mixed into the colored concrete.

Furthermore, in addition to the above-mentioned reinforcing fibers, colored concrete in which colored pigments are mixed can be made using a mortar-like material made of sand and white cement as described above, or concrete mixed with pebbles. Colored concretion based on this invention I)
- includes both aspects.

During the above manufacturing process, if the synthetic resin foam that becomes the form body 10 is used with clear granules on the mold surface side, or if the unevenness that forms a pattern is formed separately from the masonry pattern, A wide variety of decorative blocks 30, 30' can be obtained which have a granular pattern or an uneven pattern formed by expanded particles on their surfaces.

Finally, the corner decorative blocks 30 and 30' obtained by the method of the present invention are used for masonry at corners in areas where decorative concrete blocks are stacked vertically and horizontally, and are used for masonry at corners in sections where decorative concrete blocks are stacked vertically and horizontally. Just connect it to the left and right decorative concrete blocks (see Figures 6 and 11).

Corner decorative block 30 manufactured according to the present invention.
As a decorative concrete block used with 30', a hollow concrete block TO is connected and fixed to the back side of a plate-shaped decorative block 60 with uneven parts 61 and 62 made of the same material as the corner decorative block 30 and 30'. It is something that

The stacking patterns of the fallen decorative blocks 30, 30' and 60 are not limited to those shown in the drawings, but there are various patterns.

According to the method of this invention, corner decorative blocks 30 and 30 having various complex external shapes are created by combining the container-shaped formwork main body 10 and the auxiliary formwork 20 inserted and fixed therein.
' can be easily manufactured, and the masonry pattern on the surface is also formed by the concavo-convex shaped portions 12 and 11 in the form body 10.
Since the formwork body 10 and the auxiliary formwork 20 are also made of synthetic resin foam, they are lightweight and easy to handle, and can be easily formed from any position after the colored concrete has solidified. Since the decorative blocks 30 and 30' can be removed by cutting with a nichrome cut or other means, even decorative blocks with a back space 33 that is convenient for meat stealing and reinforcement arrangement, as well as decorative blocks with more complicated shapes, can be removed very easily. This means that it can be manufactured.

The formwork used for manufacturing can also be used as a packaging material for transporting decorative blocks 30 and 30' without being cut, and also has a cushioning effect when transporting decorative blocks.
It has a great protective effect.

The decorative block for corners manufactured by the method of this invention has a brick-like masonry pattern on the surface made of colored concrete and has a bent shape for corners, so it can be easily assembled for corners. When used in piling construction, especially when colored concrete is reinforced with fibers, it is extremely strong and less likely to chip or crack, resulting in strong earthquake resistance and excellent weather resistance.

It is extremely non-combustible, and because it has a bent shape in appearance, there is no joint between blocks at the center of the bend at the corner, allowing for beautiful masonry, making it easy to construct, and reducing construction costs. This will save you a lot of money.

Therefore, general housing, block housing. Concrete concrete IJ-do block construction can be widely used for the interior and exterior of buildings, hotels, inns, supermarkets, Karin stands, golf course clubhouses, coffee shops, etc., and various external fences, and can also be assembled at corners. It can be constructed without worrying about
It can exhibit various excellent effects.
