Description

[Detailed description of the invention] This invention is a formwork suitable for manufacturing decorative concrete blocks formed of colored concrete, in which hollow concrete blocks or solid blocks are connected and fixed, and also suitable for transportation. I'm trying to get .

Instead of using conventional concrete blocks, attempts have been made to embed tiles into the surface of concrete plates, for example, to achieve a beautiful surface finish.
(Refer to No. 3), tiles are not disturbed during concrete molding 1
In addition to being extremely time-consuming to lay each tile in the formwork one by one, the manufactured concrete plates with tiles must be connected reliably to the concrete plate and each tile. There is a risk of peeling, etc., and in the case of exterior use, the tiles are likely to chip or crack, and moreover, in terms of cost, when concrete plates with tiles are used, they are 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. We are trying to provide a material that is also suitable for transporting concrete blocks.

That is, the structure of the formwork according to this invention is a formwork formed into a plate shape using a resin foam, and the mold side of the formwork has a structure for forming a masonry pattern of decorative blocks. The formwork has a concavo-convex shaped part, and a drop part is formed on the outer periphery of the frame of the formwork, with a part depressed lower than the other part, and a concave-convex part for fitting the formworks together is provided. That is.

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 or the like 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 shaped like a protrusion 63, which 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.

Further, reference numeral 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, and when the hollow concrete block 70 etc. is placed after pouring the colored concrete, the colored concrete This allows the surplus portion to easily escape to this drop portion 54 on the formwork-to-blade side.

Reference numerals 55 and 55' are concave and convex portions for fitting the formworks 50 and 50 together, and they are designed to prevent displacement in the horizontal direction when stacking and transporting them, so that they are bulky and can be stacked in large numbers (Fig. 5). reference).

Note that the masonry pattern of the uneven portions 52 and 51 can be implemented in various patterns (see FIGS. 6 to 8).

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

An example of manufacturing a decorative concrete block using the formwork 50 configured as described above will be explained with reference to FIGS. Colored concrete reinforced with (
For example, use 2 parts sand to 1 part white cement and add 1 part to the length.
5TIr! A mixture of glass fiber of IL grade and some pigment) is poured in, and when the colored concrete has not yet solidified, hollow concrete blocks 70 are placed on the colored concrete and connected and fixed together by assimilation of the colored concrete. After that, if both are removed from the formwork 50,
On the surface, irregularities 61° and 62 in a masonry pattern are formed,
A decorative block 60 made of colored concrete with a protrusion 63 formed at the end can be formed, and a hollow concrete block 70 etc. are connected and fixed to the back side of this decorative block 60 to provide an integrated decorative concrete block.

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, it is possible to use a synthetic resin foam that forms the formwork 50 with clear granules on the mold surface side, or to form irregularities that form a pattern separately from the masonry pattern. 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 fibers that serve as reinforcing materials, pigments for coloring are mixed in as colored concrete, which is similar to mortar made of sand and white cement, as described above, or mixed with pebbles. Concrete-like material may be used.

In addition, for decorative books made of fiber-reinforced colored concrete, the concrete blocks that are connected and fixed to the back of the books are either hollow-shaped as shown above or solid-shaped (not shown). In some cases.

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.

The finished product after construction is such that the shape of the hollow concrete block 70 and the above-mentioned dimension adjustment protrusions 63 are invisible or difficult to see from the surface, and only the brick-like pattern is clearly visible with the unevenness, resulting in a beautiful finish. I can do it.

Furthermore, corner decorative blocks 30 and 30' made of the same material as the decorative block 60 as shown in FIGS. 9 to 12 are used for part of the corner during construction.

Corner decorative block 30.30' out of 31.32
33 is an uneven part, 33 is a back space that is convenient for meat stealing and reinforcement arrangement,
34 is a dimension adjustment protrusion.

When the formwork 50 of 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 addition, the projecting member allows for easy dimensional fine adjustment during masonry construction. It is very convenient because it can also provide the following items.

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.

Furthermore, even when not in use, they can be stored without bulk by stacking them on top of each other.

The decorative concrete block manufactured using the formwork 50 according to this invention has a decorative block 60 made of colored concrete with a brick-like masonry pattern on the surface, and a hollow concrete block on the back surface of the decorative block 60. Block 70 or solid concrete blocks are connected and fixed, so when reinforcing colored concrete with fiber mixture, the surface side becomes a tough decorative block compared to conventional blocks, and there are fewer occurrences of chips and cracks, and the surface is It will have a greater protective effect, higher earthquake resistance, and superior 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, tea rooms, coffee shops, etc., and various external fences.
