Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete secondary product for producing a concrete L-shaped retaining wall, a concrete wall, a flowerbed, etc., which has a decorative plate attached to the surface thereof.

[0002]

2. Description of the Related Art Conventionally, when an L-shaped retaining wall made of concrete to which a decorative plate is pasted, a concrete fence, a flower bed, etc. are made by using a secondary concrete product manufactured in advance in the factory, the L-shaped concrete made in the factory is used. A method of continuously building secondary concrete products on which a decorative wall such as stones and tiles has been placed together when placing retaining walls, walls, flower beds, etc. is continuously built.

[0003]

In the case of the above-mentioned construction method, the decorative plate is cut off at the joint portion of the adjacent concrete secondary product, resulting in a very bad appearance.

To solve this problem, a concrete L-shaped retaining wall, a concrete fence, a flower bed, etc. are cast on site and a decorative plate is attached to the surface, which is extremely difficult. However, there is a problem in that the cost is remarkably increased because it takes a lot of trouble and requires a considerable amount of skill to accurately attach the decorative plate.

In view of the above-mentioned problems of the conventional method, the present invention places a concrete secondary product together with a decorative plate in a factory in advance and easily makes an L-shaped concrete retaining wall on the site. The purpose of the present invention is to obtain a concrete secondary product in which concrete fences, flower beds, etc. can be placed, and at the same time, the decorative plate at the seam portion does not have edges, and to provide a construction method using the same.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a decorative plate integrally formed on the surface thereof, and the side end surface of which has the same shape as the decorative plate. The concrete secondary product was formed with a connecting recess that fits in a vertically divided shape, and a connecting decorative plate fitted over the connecting recess of the adjacent concrete secondary product. In addition, the concrete secondary product has an L-shape for forming an L-shaped retaining wall, a concrete wall for forming a concrete wall, and a shape suitable for forming a flower bed, or for connection. A structure was adopted in which a bolt was embedded in the back surface of the decorative plate and a hole for inserting the bolt was provided in the concave portion for connection of the concrete secondary product. A construction method using these concrete secondary products was also adopted.

[0007]

Since the present invention has the above-mentioned structure, the concrete secondary product of the present invention is carried to a target place by a crane or a carrier and installed at a general construction position. And
With the side edges of each secondary product in contact with each other, the connecting decorative plate is laid over the recess for connection provided on the side edge of each concrete secondary product, and the bolts on the back surface of the concrete secondary product are attached. Insert it into the hole of the connection recess of and fix the adjacent concrete secondary product by screwing the nut into each bolt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a concrete secondary product 3 for forming an L-shaped retaining wall consisting of a flat surface portion 1 and a vertical portion 2, and a connecting decorative plate 10.
Is shown. A decorative plate 4 such as a stone or a tile is attached to the surface of the vertical portion 2 of the secondary product 3. Further, a concave portion 5 having a shape obtained by vertically dividing the decorative plate 4 in half is formed at a side end portion of the vertical portion 2.

The concrete secondary product 3 is manufactured, for example, as shown in FIGS. In this case, the decorative plate 4 is arranged on the bottom plate 8 of the vertical portion forming portion 7 of the form 6, and at this time, instead of the decorative plate 4, the decorative plate 4 is vertically divided into two parts. The styrofoam plate 9 is placed.

As described above, the decorative plate 4 and the styrofoam plate 9 are arranged on the bottom plate 8, concrete is placed in the mold 6, and after the concrete is hardened, the mold 6 is disassembled and removed. When the secondary concrete product 3 is taken out and the styrofoam plate 9 is removed, a connection recess 5 is formed at the side end of the vertical portion 2 as shown in FIG.

The connecting decorative plate 10 shown in FIG. 1 has a shape that fits in the connecting recess 5 of the secondary product 3, and a pair of left and right bolts 11 are planted on the back surface of the connecting product 5 by using an adhesive or the like to make the connection. The recess 5 is provided with an insertion hole 12 into which the bolt 11 is inserted.

The secondary products 3 as described above are arranged on the ground with their side ends in close contact with each other as shown in FIG. 4, and appropriately fixed by the same construction method as the conventional one. As a result, the connection recess 5 is formed opposite to the side end of the adjacent secondary product 3.

The connecting recesses 5 are shaped so as to fit right and left on a single connecting decorative plate 10. Accordingly, the connecting decorative plate 10 is fitted while straddling the left and right recesses 5, and the bolts 11 on the back surface of the decorative plate 10 are inserted into the insertion holes 12.

Then, as shown in FIG. 5, the nut 13 is screwed into the end of the bolt 11 that is pulled out on the back surface of the vertical portion 2 to fix the connecting decorative plate 10 to the left and right vertical portions 2, and the decorative plate 10 is used. The left and right secondary products 3 are connected, and the seam cannot be seen.

FIG. 6 is the same as that of the other embodiment except that the shapes of the decorative plate 4 and the connecting decorative plate 10 are different.

In the case of a fence, the same as the above example except that there is no flat portion, and in the case of a flower bed, the same.

FIG. 7 shows a capstone 25 which is the decorative plate 4.
Made of a material similar to
Are provided at appropriate intervals. A screw hole 28 into which the bolt 26 can be screwed is provided on the upper end surface of the concrete secondary product 3 shown in FIG. In this case, the fence is constructed in the same manner as described above, and the cap stone 2 is placed on each of the concrete secondary products 3 of the fence.
5, the bolts 26 inserted into the respective insertion holes 27 are screwed into the respective screw holes 28 and fixed.

FIGS. 8 and 9 show another embodiment, in which the cap stone 25 is attached to the top surface of the vertical wall 2 by providing a recess 31 in the cap stone 25 as shown in FIG. A concave portion 32 is provided on the surface, and a bolt 34 fixed with a mortar 33 or the like is erected on the concave portion.
And is fixed by bolts 35.

[0019]

The concrete secondary product of the present invention has a decorative plate integrally cast on the surface thereof, and has a side end surface of which the same shape as the decorative plate is vertically divided into half. Since a connection concave portion that conforms to the above is formed, when installing an L-shaped retaining wall or a fence with a concrete secondary product, the connection decorative plate is laid across the connection concave portion of the adjacent concrete secondary product. By fitting in such a manner, the connecting decorative plate hides the joints between the adjacent secondary concrete products, so that an L-shaped retaining wall, a fence, a flowerbed, etc. having an extremely good appearance can be easily obtained.
