Description

[Detailed description of the invention] This invention attempts to obtain a decorative concrete block in which a hollow concrete block or a solid concrete block is connected and fixed to a decorative block formed of colored concrete reinforced with glass fibers.

Instead of the conventional simple concrete block, attempts have been made to embed tiles on the surface of a concrete board to achieve a beautiful surface finish (see Japanese Utility Model Publication No. 5903/1983), but it has been attempted to embed tiles without disturbing them during concrete molding. In addition to being very time-consuming to install each tile in the formwork one by one, the manufactured concrete plate with tiles may come apart if the concrete plate and each tile are not connected reliably. There is a risk of causing
Furthermore, when used for exterior purposes, the tiles tend to chip or crack, and moreover, when concrete plates with tiles are used, they are expensive.

Therefore, in this invention, we are trying to provide 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.
Its structure is to form a decorative block with a brick-like masonry pattern on its surface using colored concrete reinforced with glass fibers, and a hollow concrete block or solid concrete block is connected and fixed to the back of the decorative block. It is further characterized in that a projection for dimension adjustment is formed at one end of the upper and lower ends of the decorative block on the masonry side to protrude from one end of the upper and lower ends of the concrete block.

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

The decorative concrete block is shown in FIG. 3, where 60 is a decorative block and 70 is a hollow concrete block connected and fixed to the back side of the decorative block 60. The above makeup block 60
is colored concrete reinforced with glass fibers, for example, it is made of 2 parts sand to 1 part white cement, mixed with about 3% glass fibers with a length of about 15 mm and some pigment. Hollow concrete block with mortar 70,7
The upper and lower ends of the concrete block 70 are longer than the concrete block 70 in consideration of the connection between the 0s, and the surface is provided with uneven portions 61 that form a brick-like masonry pattern.
62. Numeral 63 is a dimension adjustment protrusion formed at one end of the upper and lower ends of the masonry side of the decorative block 60, and is formed to protrude beyond one end of the upper and lower ends of the concrete block 70, and is removed by the necessary amount during masonry construction. Used to make fine adjustments to masonry dimensions.

An example of manufacturing for obtaining a decorative concrete block having the above structure will be explained based on FIGS. Colored concrete that will become the decorative block 60 reinforced with glass fibers is poured into a plate-shaped formwork 50 made of synthetic resin foam that has formed the shaped parts 52 and 51, and hollow concrete is formed at a stage where the colored concrete has not yet hardened. After the block 70 is mounted and connected and solidified by solidifying the colored concrete, it is removed from the formwork 50 to provide an integrated structure. 53 of the formwork 50 is a dimension adjustment protrusion 6
When the hollow concrete block 70 is placed on the hollow concrete block 70 during manufacture,
Excess colored concrete can only be pushed out to one side of the formwork. 55, 55' is formwork 5
It is a concave and convex portion for fitting between 0.0 and 50 mm, making it easy to stack and store and transport the formwork when it is not in use. (See Figure 5).

The formwork 50 may be formed of a foam formed by heat-foaming expandable thermoplastic resin particles (beads) and heat-sealing them to each other, or may be formed from an extruded foamed sheet. It is also possible to use a mold 50 formed from a foam by press molding or the like.

Furthermore, in addition to the above-mentioned glass fiber that serves as a reinforcing material,
As for the colored concrete in which pigments are mixed for coloring, it is carried out using something similar to mortar made of sand and white cement as mentioned above, but it may also be carried out using something similar to concrete mixed with pebbles. The colored concrete according to this invention includes both aspects. In addition, for a decorative block made of colored concrete reinforced with fibers, the concrete block connected and fixed to the back side may only have a hollow shape like the one described above.
In some cases, it is carried out using a solid shape.

During the above manufacturing process, use a synthetic resin foam that becomes the formwork 50 with clear agglomerates on the mold surface side, or form irregularities that form a pattern separately from the masonry pattern. Among the decorative concrete blocks thus produced, a wide variety of decorative blocks 60 having a granular pattern or an uneven pattern formed by foamed particles on the surface thereof can be obtained.

In addition, the decorative concrete blocks of this invention only need to be stacked sequentially vertically and horizontally according to the intended shape according to the masonry pattern. Mortar M sequentially in parts
(See Figure 4).
Particularly in the case of this invention, a projection 63 for dimension adjustment is formed at one end of the upper and lower ends of the masonry side of the decorative block 60 so as to protrude from one end of the upper and lower ends of the concrete block 70, so that the masonry dimensions can be finely adjusted as described above. This helps ensure that the process is carried out reliably, and the finish can be in better condition than with conventional construction. In addition, after construction, the shape of the hollow concrete block 70 etc. becomes invisible from the surface, and only the brick-like pattern is displayed, resulting in a beautiful finish (see FIGS. 10 and 12). The above-mentioned patterns are not limited to those shown in the figure, and there are various patterns (6th pattern).
(See Figures 8 to 8). Furthermore, corner decorative blocks 30, 30' made of the same material as the decorative block 60 are used at the corner portions during construction to suit the shape of the corner to be constructed (see FIGS. 9 to 12). This makeup block 30,3
As 0', it is preferable to have a back space 33 for convenience in meat stealing and reinforcing, etc., and 34 indicates a protrusion.

In this invention, as mentioned above, a decorative block 60 having a brick-like masonry pattern on the surface is formed of colored concrete reinforced with glass fiber, and a hollow concrete block 70 or a solid concrete block ( (not shown) are connected and fixed, so the decorative block 6 on the surface side is stronger than conventional blocks.
0, the occurrence of chips, cracks, etc. is small, the surface protection effect is large, the seismic strength is high, and the weather resistance is also excellent. In addition, the overall non-combustibility is improved, and the appearance is beautiful as it has irregularities suitable for the pattern. Joints are created just by masonry, and are formed at one end of the masonry side of the decorative block. Coupled with the ease of dimensional adjustment using the dimensional adjustment protrusions, construction is easier and construction costs can be reduced significantly.

Therefore, this product can be used in general houses, block houses, buildings, hotels, inns, supermarkets,
It can be widely used for the interior and exterior of gas stations, golf course clubhouses, coffee shops, etc., as well as various types of exterior shelves, and can exhibit excellent effects.
