Description

[Detailed Description of the Invention] This invention provides a precast board with a large-scale surface that is designed to be used in places where aesthetic appearance is extremely important, such as coasts and bay mouths adjacent to national parks and natural parks. The present invention relates to a pre-cast decorative board with corrugations for constructing retaining walls.

When constructing a concrete structure such as this type of retaining coating, it should be constructed by pouring concrete in harmony with the park, etc., and by placing decorative blocks etc. from the landscape side by side. However, in this case, it is good when the height of the false wall is low, but when constructing a high tower or a large-scale retaining wall structure with a large tonosho, conventional decorative blocks, etc. When considering the stability of the retaining wall structure, it has the drawback that its resistance to soil is extremely low, and the construction is very troublesome and requires a lot of effort and time. Therefore, this invention buries fossilized fender stones on the front side of the vertical reinforcing bars, and also erects a large number of precast toy Q ship plates with wave return parts, and several precast toy Q salmon plates are installed on the back side of the precast toy Q salmon plates. Embedded metal fittings are embedded at predetermined intervals.

The vertical reinforcing bars and the embedded metal fittings are reinforced with horizontal reinforcing bars or the like, and metal forms are arranged on the rear side of the vertical reinforcing bars and tied together with reinforcing bars or the like. Then precast toy Q
The internal space between the board and the metal form is filled with concrete so that they are constructed as one unit. Therefore, decorative precast toy deck boards with corrugations can be easily and reliably constructed in places that require an aesthetic appearance similar to parks, etc., and also in high sun walls and earth retaining works that require a lot of manpower. This makes it easy to obtain a strong, beautiful foundation wall. Next, an embodiment of the present invention will be explained with reference to the drawings.The grand wall main body 1 has decorative stones such as natural stones on the front side of the vertical reinforcing bars 3, 3, etc., that is, on the surface side facing the coast, the bay mouth, etc. .5・
. . . is buried, and a standing portion 8 is provided at the top,
Precast toy drop plates 4, 4, .

Several embedded fittings 6, 6... are embedded at predetermined intervals on the back side of the precast decorative boards 4, 4.... Next, the vertical reinforcing bars 3, 3, . . . and the embedded metal fittings 6, 6, . Metal forms 12, 12... are arranged on the rear side of the vertical reinforcing bars 3, 3..., and steel vertical ends 13, 13... are arranged on the outside thereof.
・are arranged vertically at predetermined intervals. Also, vertical reinforcing bars 3, 3
...... is metal form 12, 12 with rhombus striped reinforcement. Reference numeral 11 indicates a plate buried in the foundation retaining wall 2, 14 is a separator used for the foundation rock wall 2, and the separator 14 is connected to the rear metal form 12 and the vertical end 1
3 and the steel machine block 15 on the outside thereof using fasteners 17, 17. In addition, the front side of the separator 14 is attached, for example, to the front surface of the lower precast decorative board 18 arranged below the precast decorative board 4 through a center 19 from the steel horizontal end large 15 with a vertical odor 17. This shows the condition in which it has been forced. Next, reference numeral 16 indicates reinforcing reinforcing bars for horizontal connection, which are used in addition to binding the vertical reinforcing bars 3, 3 and the horizontal reinforcing bars 9, as shown in FIG. 20 shows concrete that is injected and filled between the precast decorative board 4 and the metal form 12 to construct a support.

According to this invention, large-scale precast decorative boards can be easily installed on large-scale retaining walls and large-height retaining walls on large tonosho blocks, which would be impossible with conventional Ikyunso blocks. It is very convenient and has the effect of shortening the construction period and making it stronger due to the ease of construction.

In addition, a decorative stone made of natural stone or the like was buried on the surface of this precast toy Q plate, and a wave return part was formed, so that the decorative stone part on the surface maintains its beauty for a long time and is suitable for the coastline and the harp. It is suitable for the aesthetic appearance of the mouth, and the wave-returning part is sufficient to withstand storms, and since the wave-returning part is formed integrally with the decorative board, it has the effect of being extremely strong. In addition, since the embedded metal fittings and vertical reinforcing bars provided on the back of the precast toy Q board are tied together with horizontal reinforcing bars, the precast decorative board can be maintained stably, and a large number of precast toy Q board can be correctly connected. They are aligned and have the effect of constructing retaining walls with very good aesthetics. Furthermore, according to this invention, the retaining wall construction involves installing large precast toy Q-hoko boards with an unprecedented decorative surface on the surface of the retaining wall, and integrating them by pouring concrete inside the wall. Precast decorative boards mass-produced in this way are inexpensive, large-sized decorative boards can be easily manufactured, and there are advantages such as being very economical because construction is easy.
