BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer material made of synthetic resin for concrete casting, in which a pattern designed in advance is provided on the surface of the concrete to be cast.

[0002]

2. Description of the Related Art Conventionally, in many cases, various civil engineering works, retaining walls for flood control work, and the like have been constructed by concrete in terms of durability, material cost, construction cost, and the like. However, in recent years, from the viewpoint of harmony with the natural environment, ensuring a comfortable living environment, etc., the background of the concrete, which has an inorganic and artificial appearance, tends to be shunned. A concrete construction method has been developed that exhibits the appearance of a pattern such as. Examples of such a construction method and a formwork used for this are, for example, JP-A-63-63
Many proposals have already been made, including Japanese Patent Publication No. 147606, Japanese Patent Laid-Open No. 63-107512, Japanese Utility Model Laid-Open No. 1-76203, and the like.

[0003] In all of these proposed techniques, as a basic constitution, a foam made of a synthetic resin has a concave portion having a pattern appearance such as a masonry on one surface and a convex portion corresponding to a joint portion, and the back surface thereof. Uses a formwork of the type that is attached to a steel or wooden panel with an adhesive or the like. By the way, when concrete is poured into a mold as described above and cured, a synthetic resin foam such as expanded polystyrene generally tends to adhere to the concrete side, so that after concrete curing. It takes a lot of time to remove the formwork, and it is difficult to process the residual material. Moreover, since the synthetic resin foam adheres to the concrete side as described above, the formwork is discarded after one use, which is very uneconomical.

On the other hand, a mold provided with a concave portion and a convex portion corresponding to a joint portion is prepared, and a synthetic resin sheet is used by using the mold.
By vacuum-forming the resin, a synthetic resin vacuum-molded product with the desired appearance can be obtained, so if this is bonded to a steel panel and used in concatenation, it is possible to achieve the intended purpose. is there. However, in the case of vacuum forming, only one surface can be formed at a time, and it is necessary to attach the surface sheet separately or to attach using a so-called auxiliary tool, which is troublesome, Moreover, the production cost is high. As a modification to these problems, by the blow molding method using a thermoplastic resin,
A concrete formwork for forming patterns such as masonry is conceivable in which a formwork is integrally formed by blow molding of the front side having the surface of the recess and the rib and the backside having the backside and is formed into a hollow body. There is.

[0005]

However, in the above-mentioned conventional transfer material, the shape of the transfer surface is mainly 4
The polygonal shape is extremely poor in the variety of patterns because only one type of the rectangular shape is repeatedly arranged. Further, as disclosed in Japanese Patent Laid-Open No. 63-147606, it is disclosed that squares and rectangles are combined to give variety of patterns, but both squares and rectangles are quadrangular, and combinations of these are also disclosed. By itself, such a great variety cannot be obtained. On the other hand, in the conventional transfer material, after assembling a large number of transfer materials in a wall shape, the fastening position of the tie bar is previously determined at the stage of fastening the tie bar for supporting and fixing the wall from the rear part. Since it does not exist, it takes time and effort to select a suitable position from the rear part and make a hole with a drill or the like.

In the present invention, the inventors of the present invention, which should overcome these problems, have made a great deal of efforts and as a result, have a good releasability from a casting concrete, can be repeatedly used, and have excellent durability. Further, to provide a transfer material made of synthetic resin for pattern forming concrete placing, which has sufficient strength, is easy to handle, has excellent workability, and is extremely versatile in masonry etc. which can be manufactured at low cost. The purpose is.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view showing a pattern formed by combining octagons, squares and trapezoids on the surface of a casting concrete according to the present invention. That is, as shown in FIG.
And the combined arrangement of the square 2 and the trapezoid 3,
It forms an integral pattern. Further, the polygon formed of the octagon 1 does not necessarily have to be a regular polygon, and does not contact the diagonal side, that is, the unit piece of the quadrangle 2 among the octagons forming the octagon 1 shown in FIG. The sides are longer than the horizontal and vertical sides, which reduces the rotational freedom when assembling polygonal unit pieces because they are not regular polygons, but after assembling the square unit pieces, the octagonal unit pieces are easy to install. Can be assembled to. Further, the trapezoidal 3 unit piece corresponds to a part of the octagonal unit piece. Further, each quadrangle 2 is provided with a tie bar mounting hole 4 so that the tie bar is mounted at this position.

FIG. 2 is a plan view showing a pattern formed by a combination of hexagons, squares and trapezoids on the surface of a casting concrete showing another embodiment according to the present invention. In this way, as shown in FIG. 2, hexagons 5, squares 2 and trapezoids 3 are combined to form a pattern, and unit pieces having the same three kinds of shapes are freely combined to form an octagon as a whole. A tie bar mounting hole is provided at the center of the quadrangle 2 at the center of the tie bar, and the tie bar is mounted and fixed in this hole.

FIG. 3 is a plan view showing a surface pattern of a casting concrete showing another embodiment according to the present invention. Thus, as shown in FIG. 3, four pentagons 6 are combined around the quadrangle 2 to form a square, while the four
The squares form an octagonal pattern. Moreover, for fixing, a tie bar mounting hole 4 is provided at the center of the square 2.

FIG. 4 is a plan view showing a surface pattern of a casting concrete showing another embodiment according to the present invention.
Thus, as shown in FIG. 4, a regular hexagon 7 and a triangle 8
It is a pattern that combines two types of
In that case, a hexagon is formed by two hexagons formed by only hexagons and triangles as a whole by alternately contacting other hexagons and triangles on each side of the hexagon. is doing. Also, FIG. 4 (B) is a combination of two types of regular hexagon 7 and triangle 8, but the way of combining is different from FIG. 4 (A), and a triangle is connected to every other side of the hexagon. However, the hexagons 7 are arranged on the upper and lower sides of the hexagon 7, and the two left and right sides of the hexagon are arranged in contact with each other. The tie bar mounting holes may be provided, for example, in the hexagon 7 at appropriate intervals to mount the tie bars.

FIG. 5 is a plan view showing the surface pattern of a casting concrete showing another embodiment according to the present invention.
FIG. 5 shows a pattern formed by combining two types of regular hexagons and rhomboid squares. In FIG. 5 (A), regular hexagons 7 are combined with rhombic squares 9 every other side to form regular hexagons. A combination pattern with a three-dimensional regular hexagon composed of a rhombus is formed at the center. Also, FIG.
Similarly, (B) is a combination of two types of regular hexagon 7 and rhombus quadrangle 9, and the combination method is as shown in FIG.
Unlike (A), a shape that forms a large vertically long hexagon by placing rhombic quadrangles in contact with two continuous sides of a regular hexagon, and arranging them so that two rhombic quadrangles contact continuously It makes a pattern.

As described above, by combining a plurality of polygonal transfer unit pieces having different numbers of angles, it is possible to obtain a variety of pattern changes as if natural stones were embedded. In particular, if a polygonal transfer unit piece having a large number of corners is assembled and configured, the variety thereof is further improved. However,
A polygonal transfer material having at least one curved side, or two or more transfer materials having different shapes may be used as long as similar versatility can be obtained. Moreover, the hollow body transfer material is a polyolefin resin, in order to bring out the pattern of natural stones,
For example, a transfer material to be formed into a concave portion corresponding to a pattern such as a natural stone to be transferred on one surface by using a resin composed of polyethylene, polypropylene, a modified product thereof, and a compound thereof is used. By using such a polyolefin-based resin, the releasability from the casting concrete is excellent, and the recycled use becomes easy.

Next, FIG. 6 is a sectional view of a hollow body transfer material according to the present invention. In FIG. 6, in order to fix the hollow body transfer material 11 of the present invention to the mold 10, a tie bar mounting hole 4 through which a tie bar 12 for screwing the tie bar 12 with the mold 10 is inserted is opened. Has been. In addition, the hollow body transfer material 11 is formed such that the contact surface portion between the mold 10 and the hollow body transfer material 11 is formed in a concave shape, and is in contact with the surface of the casting concrete 13 surface.
Is formed into a protruding shape to form a crimp portion 14 for closing a part of the hollow body, and the crimp portion 14 is configured to penetrate the tie bar mounting hole 4. With such a configuration, when the concrete 13 is put into the outside of the hollow body transfer material, the concrete 13 exudes in the direction of the arrow and the concrete is collected in the pressure-bonding portion 14.
However, the present invention is not limited to the hollow body transfer material formed by hollow molding, and is applied to a concrete casting formwork in which a plate-shaped transfer material is obtained by vacuum forming and the plate-shaped transfer material is joined to a steel panel. You may.

With this structure, the tie bar mounting hole 4 of the hollow body transfer material is formed in the portion where the surface opposite to the transfer surface is pressure-bonded, so that the unconsolidated concrete is temporarily removed. Even if it may exude from the gap of the hole 4, it is only a passage to the outside of the hollow body, and therefore,
It does not penetrate into the hollow body. Moreover, the location where the surface opposite to the transfer surface is crimped has the same effect as if a cylindrical column was erected from the surface on the opposite side to the transfer surface, so that a reinforcement for the pressure exerted by the concrete on the transfer surface. It is also accompanied. Therefore, the thickness of the transfer surface itself can be reduced. In addition, the transfer material can be used repeatedly, which contributes to resource saving, and even if the concrete adheres to the surface of the transfer material, it can be easily removed so that it can be used many times and then recovered. It can be recycled and contributes to environmental conservation.
