Description

[Detailed explanation of the invention] This invention aims to obtain a formwork suitable for manufacturing decorative concrete blocks formed of colored concrete, in which hollow conchnaut blocks or solid blocks are connected and fixed. There is.

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 reliable connection between the concrete plate and each tile. If this is not done properly, there is a risk of individual tiles peeling off, etc. Also, when used for exterior use, tiles are likely to chip or crack, and in terms of cost, when using concrete plates with tiles, It 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 above-mentioned concrete board with tiles, but this decorative concrete block is colored. Since a hollow concrete block or a solid concrete block is connected and fixed to a plate-shaped decorative block made of concrete, a formwork suitable for manufacturing is required. intended to provide.

That is, the structure of the formwork according to this invention is such that a plate-shaped formwork is formed of synthetic resin foam, and the formwork has an uneven portion forming a masonry pattern of decorative blocks on the mold surface side. Furthermore, on one side of the upper and lower stacked ends of the decorative blocks on the mold surface side, a drop portion is formed that is lower than the other parts of the frame periphery.

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

Reference numeral 50 denotes a formwork according to this invention, which is formed into a plate-like frame using synthetic resin foam such as polystyrene foam.

Then, on the mold surface side of the formwork 50, there is a decorative block 6 to be manufactured.
It has uneven parts 52 and 51 for forming uneven parts 61 and 62 of a masonry pattern of 0, and colored concrete is poured into the formwork 50 and a hollow concrete block etc. is placed on top of it. The convex portion 51 on the mold surface is formed lower than the outer periphery of the frame.

Reference numeral 53 denotes a small concave portion for forming a protrusion 63, 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 60.

Furthermore, 54 is a drop part, in which the outer periphery of the frame is lowered lower than other parts at the end on the side where the recessed part 53 is formed,
When a hollow concrete block 70 or the like is placed after colored concrete is poured, the excess colored concrete is made easy to escape to this drop part 54.

55 and 55' are uneven parts for fitting the formworks 50 and 50 together, and are designed to prevent displacement in the horizontal direction when stacked and transported, and are low bulky so that a large number of them can be stacked (Fig. 5). reference).

It should be noted that the masonry pattern of the uneven portions 52, 51 can be implemented in various patterns (see FIGS. 6 to 8).

The formwork 50 can be manufactured by forming a foam made by heat-foaming expandable thermoplastic resin particles (beads) and heat-sealing them to each other, or by forming a foam made from an extruded foamed sheet. It is also possible to form the mold 50 by means such as press molding.

To explain an example of manufacturing a decorative concrete block using the formwork 50 configured as described above, first, the formwork 50 is filled with plain colored concrete or colored concrete reinforced with glass fiber (for example, sand 2 , a mixture of 1 part self-cement and glass fibers of about 15 mm in length and some pigment) is poured into the concrete, and a hollow concrete block 70 or the like is placed on the colored concrete before it solidifies. The surplus colored concrete will not escape to both ends of the formwork 50, but will escape to the drop portion 54 formed at one end of the formwork 50.

After the colored concrete is solidified and connected and fixed to each other, if both are removed from the formwork 50, the colored concrete is formed with irregularities 61 and 62 in a masonry pattern on the surface and protrusions 53 at the ends. A decorative block 60 is created, and a hollow concrete block 70 is placed on the back side of this decorative block 60.
It is possible to provide a decorative concrete block in which these parts are connected and fixed in an integrated manner.

The decorative block 60 made of colored concrete is formed to be longer at the upper and lower ends than the concrete blocks 70 in consideration of the connection between the hollow concrete blocks 70 and 70 made of mortar.

During the above manufacturing process, if a synthetic resin foam that becomes the formwork 50 is made of a material with clear granular properties on the mold surface side, or if unevenness is formed to form a pattern separately from the masonry pattern, the manufacturing process can be improved. A wide variety of decorative blocks 60 having a granular pattern or an uneven pattern formed by foamed particles can be obtained on the surface of the decorative block 60.

In addition, in place of the above-mentioned glass fibers, other fibers (for example, nylon fibers) may be mixed into the colored concrete and used.

Furthermore, in addition to the above-mentioned reinforcing fibers, pigments for coloring are mixed in as colored concrete, which is similar to mortar made of sand and white cement, as described above, or concrete mixed with pebbles. Sometimes a shape is used.

Also, for decorative blocks made of fiber-reinforced colored concrete, the only concrete blocks that can be connected and fixed to the back side are the hollow shapes shown above.
It may also be implemented using a solid shaped one (not shown).

In addition, the decorative concrete blocks manufactured using the formwork of this invention only need to be stacked sequentially vertically and horizontally according to the intended shape according to the masonry pattern, and are connected to the back side of the decorative block 60 during masonry work. The parts of the hollow concrete block 70 that are fixed may be successively connected by masonry using mortar M (see FIG. 4).

In particular, since the protrusion 63 is formed at the end of the masonry, the masonry dimensions can be easily finely adjusted by cutting off the required amount, and masonry can be done in a beautiful pattern.

In addition, during manufacturing, it is easy to remove surplus colored concrete concentrated on the side of the drop 54 after manufacturing, and during construction, the surplus colored concrete is located on the concave side of the masonry pattern and is hidden, making it easier to make hollow concrete. Coupled with the fact that the blocks are not visible, the exterior appearance after masonry construction is good, and a beautiful finish can be achieved.

Furthermore, corner decorative blocks 30, 30' made of the same material as the decorative buoy lock 60 are used for part of the corner during construction.

This corner decorative block is 30.31 of 30'.
Reference numeral 32 indicates an uneven portion, 33 indicates a space on the back which is convenient for removing meat and arranging reinforcement, and 34 indicates a protrusion for adjusting dimensions.

When the formwork 50 according to this invention is used, it becomes easy to form a masonry pattern on the surface, and a decorative concrete block can be manufactured easily.

In particular, it is very convenient that surplus colored concrete can be appropriately disposed of by using the drop portion 54 during manufacturing.

In addition, since the formwork 50 is made of synthetic resin foam, it is lightweight and easy to handle, and can also be used as a packaging material for transportation without removing the decorative concrete blocks, providing a cushioning effect during transportation. The colored concrete has a great protective effect on decorative block parts.

The decorative concrete block manufactured using the formwork 50 according to this invention has a decorative block 60 with a brick-like masonry pattern on the surface using colored concrete, and a hollow space on the back side of the decorative block 60. Since concrete blocks 70 or solid concrete blocks are connected and fixed, when reinforcing colored concrete with fiber mixture, the surface side becomes a stronger decorative block 60 compared to conventional blocks, which prevents chipping, cracking, etc. less,
It has a large surface protection effect, has high earthquake resistance, and has excellent weather resistance.

In addition, the overall non-combustibility is improved, the appearance is beautiful, and the joints are created just by assembling, making construction easy and resulting in significant savings in construction costs.

Therefore, the decorative concrete block manufactured above is
It can be widely used for the interior and exterior of general houses, block houses, buildings, hotels, inns, supermarkets, gas stations, golf course clubhouses and tea rooms, coffee shops, and various external fences.
