Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing decorative concrete blocks by pouring colored concrete, which greatly facilitates manufacturing.

Instead of the conventional concrete block, attempts were made to embed tiles into the surface of a concrete plate to achieve a beautiful surface finish.
Publication No. 3), 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 the connection of the concrete plate and each tile. If this is not done reliably, there is a risk of individual tiles peeling off, etc. Also, when used for exterior purposes, tiles are likely to chip or crack, and it is also cost-effective to use concrete plates with tiles. It was expensive to use.

Therefore, in this invention, we have developed a unique decorative concrete block that is much cheaper, easier to manufacture, and has superior strength compared to the above-mentioned concrete board with tiles. For the plate-shaped decorative block that was formed,
Hollow concrete blocks or solid concrete blocks are connected and fixed, and a unique pattern is required to improve the appearance, and the manufacturing method is to easily create a pattern and obtain a beautiful product. An efficient and stable method is required.

Therefore, the present invention satisfies the above requirements by having an uneven pattern on the inner surface of the formwork made of synthetic resin foam, separate from that for the masonry pattern. A plate-shaped formwork is formed from synthetic resin foam, and an uneven part is provided on the side of the formwork to form the masonry pattern of decorative blocks, and furthermore, on the outer periphery of the side frame of the formwork, an uneven part is provided to form a masonry pattern of decorative blocks. In addition to forming a drop part where a part is lower than the other part, an uneven part for fitting the formwork is provided, and colored concrete is poured into the formwork, and a cavity is formed when the colored concrete is not yet solidified. This is a method of manufacturing a decorative concrete block by placing a concrete block or a solid block on top of colored concrete and connecting and fixing the two as the colored concrete solidifies.The inner surface of the formwork has irregularities on the surface of the foam, apart from the masonry pattern. Forming a pattern in the form of a pattern [No. 11] Pour blue concrete reinforced with fibers into the formwork to form the pattern on the surface of the decorative concrete block as a three-dimensional pattern separate from the IIv4 pattern. It is characterized by:

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

First, (10) is a mold used in the present invention, which is formed into a plate-shaped frame made of synthetic resin foam such as polystyrene foam. Then, on the mold surface side of the formwork (10), there are irregularities (2) of the masonry pattern of the decorative block (20) to be manufactured.
1) Concave and convex shaped portion (12) for forming (22)
(it) and an uneven pattern part (b) having a background pattern or a large pattern for forming the uneven pattern part (B) is formed separately from the above-mentioned uneven parts (12) and (11). . Because colored concrete is poured into the formwork (10) and hollow concrete blocks (30) are placed on top of it, the convex portion (10) of the formwork surface is
1) is formed lower than the outer periphery of the frame. (13) is a small recess for forming a protrusion (23), and is formed in a portion of the mold surface that is at least one of the upper and lower stacked ends of the decorative block (20). Furthermore (14)
is a drop part, and the outer periphery of the frame is lowered lower than the other part at the end on the side where the recessed part (13) is formed, and after pouring colored concrete reinforced with fibers, a hollow concrete block etc. is placed on it. At this time, the surplus part of the colored concrete is made easy to escape to this drop part (14), and the surplus part is guided to an inconspicuous place after construction. (1
5) (15') is a concave and convex part for fitting the formworks (10) (10) together, and is designed to prevent horizontal displacement when stacked and transported, and is low in bulk so that it can be used in large numbers. (See Figure 5).

The formwork (10) may be formed of a foam formed by heat-foaming and heat-sealing expandable thermoplastic resin particles (beads), or may be formed by extrusion foaming. It is also possible to use a mold (10) made of a foamed sheet formed by press molding or the like.

When manufacturing a decorative concrete block using the formwork (10) as described above, colored concrete reinforced with nylon or glass fiber is first poured into the formwork (10)'. At the initial stage, the hollow concrete blocks 1 to 30 (30) or the solid concrete part (U shown in the figure) are placed on the colored concrete and connected and fixed together as the colored concrete solidifies. When removed from the wall, the uneven parts (21) and (22) of the masonry pattern are formed on the surface, and an uneven pattern part (B) separate from the pattern is formed, and a protrusion is also formed on the end of the masonry side. A decorative block (20) is made of colored concrete formed with (23), and on the back side of this decorative block (20) there is a hollow concrete block (30
) etc. can be connected and fixed to provide an integrated decorative concrete block. The above-mentioned decorative block (20) made of colored concrete is formed to be longer at the upper and lower ends than the concrete block (30) in consideration of the above connection (30). (See Figure 4).

Note that the masonry pattern of the uneven portions (21) (22) can be implemented in various patterns (see FIGS. 6 to 8).

Next, in the drawings, cylinder figures 9 to 12 and figures 15 to 1
Figure 7 shows a formwork for manufacturing decorative blocks used for corners by appropriately connecting decorative concrete blocks manufactured according to the present invention, (50) is a hollow-shaped formwork body, (6G) (60 ') is an auxiliary formwork, both of which are made of synthetic resin foam such as polystyrene foam. Inside the formwork body (50), there are uneven portions (5) for forming uneven portions (71) (72) of the brick-like masonry pattern of the corner decorative block (70).
2) (51), and a scale uneven pattern part (a) for forming a ground pattern or a large pattern separately from this masonry pattern is formed on the surface of the foam. The above auxiliary formwork (6G) (6G') is a decorative block (7
G) This is to form the back side space (γ3) of (7G') to serve as a fillet and reinforcement section, etc., and is separate from the formwork body (50) at the mutual fitting section (53) ( 63) and are connected and fixed by adhesive, fusion, or other means. (64) is the meat stealing department. In addition, the formwork body (5
0) may be implemented by forming recesses for forming dimension adjustment protrusions at one of the upper and lower ends of the decorative block on the masonry side, if necessary. Such a protrusion can be used to finely adjust the masonry dimensions by cutting off the required m during masonry construction of decorative blocks. The formwork has a shape that corresponds to the shape of the corner decorative blocks (70) (70'), and the uneven portions (52) (51) that form the masonry pattern of the formwork body (50) are There are cases in which a rectangular decorative block (70) is manufactured in a square shape (see Figs. 9 to 14), and cases in which an arc-shaped decorative block (yo') is manufactured in an arc shape (see Figs. 15 to 14). (See Figure 17). Corner decorative block (70) (7G

C) Colored concrete reinforced with mortar-like or concrete-like nylon, glass fiber, etc. (for example, mixed with glass mill fibers of about 15 mm in length and some pigment at a ratio of 2 parts sand to 1 part white cement) After solidification, formwork main body (50) and auxiliary formwork (60) are poured.
(60') is cut from appropriate locations using a nichrome cut or other means to create corner decorative blocks (70) (70')
All you have to do is take it out. Then, in the next production, a new formwork main body (50) and auxiliary formwork (60) (60') may be used. In the above manufacturing, in addition to the unevenness ((71)) and (12) of the pattern on the masonry pattern side, the uneven pattern (
Decorative block (70
)(70') will be easily provided.

Next, an example of use of the decorative concrete block obtained by this invention will be described.

The above-mentioned decorative concrete blocks only need to be stacked sequentially vertically and horizontally according to the intended shape according to the masonry pattern.During the masonry work, the hollow concrete block (7G) is connected and fixed to the back side of the decorative block (60).
) can be connected sequentially using mortar (M) (see Figure 4). Especially the protrusion (63) at the masonry end.
Since it is formed, it is easy to make fine adjustments to the masonry dimensions by cutting off the required amount and creating a beautiful pattern.
4 can be done on 11th. After construction, the shape of the hollow concrete block (γ0) and the above-mentioned dimension adjustment protrusion (63) will be invisible or difficult to see from the surface;
Only the brick-like pattern is clearly visible in the unevenness, resulting in a beautiful finish. In addition, in a part of the corner, the above-described corner decorative blocks (70) (70') may be sequentially stacked and connected to the left and right decorative concrete blocks.

As described above, according to the present invention, it is possible to obtain a decorative concrete block with a prominent uneven pattern on the surface separate from the masonry pattern, but from the foam for forming the uneven pattern. Regarding the uneven pattern part of the formwork, there are cases where the uneven pattern part is formed at the same time as molding using a molding die, and cases where the desired uneven pattern part is formed using a solvent etc. after molding the inner surface of the formwork with a smooth surface. Any material formed on the inner surface of the mold may be used.

As described above, according to the present invention, a decorative concrete block having a concavo-convex pattern clearly expressed on the masonry pattern side separately from the pattern by the concavo-convex pattern formed on the foam surface of the plate-shaped formwork can be easily manufactured. This method allows for beautiful, efficient and stable production of the formwork, and because it uses a formwork in which a part of the outer periphery of the formwork is sunk lower than the other part to provide a drop, excess colored concrete that has been poured in excess can be avoided. The material is quickly guided to the outside of the formwork through this drop, and the concrete block and the masonry pattern formed on its surface are not misaligned, making it possible to manufacture beautiful decorative concrete blocks. , Even when stacking a large number of formworks for block manufacturing, using a formwork with uneven parts formed on the outer periphery of the formwork for fitting the formworks to each other allows for safe and smooth work without shifting in the horizontal direction. able to perform work.

In addition, this method can be manufactured not only in factories but also at construction sites, and by using molds made of synthetic resin foam, decorative concrete blocks with complex external shapes can be manufactured on hour wheels, and the surface It is extremely easy to form an uneven pattern and a masonry pattern. In addition, the τ1 frame used is lightweight and easy to handle, and has good cushioning properties, so it can be used as a packaging material for transportation without removing the decorative concrete blocks.In this case, the protective effect of the colored concrete on the decorative blocks can be It's a big b.

In addition, since the colored concrete reinforced with m-fiber mixture is used, it has excellent shape retention, and the uneven patterns formed on the block surface, especially the protrusions, come into contact with the formwork during block molding, resulting in damage. It can prevent chips from falling off due to contact with other objects after construction, and −
S is tougher, less likely to chip, crack, etc., and has a good surface protection effect.

Furthermore, it will have higher overall earthquake resistance, as well as superior weather resistance and non-combustibility. The exterior is beautiful, and the joints are completed just by masonry, making construction easy and resulting in significant savings in construction costs.

Therefore, it can be applied to the interior and exterior of general houses, block houses, buildings, hotels, inns, supermarkets, gas stations, golf course clubhouses, coffee shops, etc., as well as various external fences, etc., and exhibits excellent effects.
