Description

Detailed Description of the Invention "Industrial Field of Application" The present invention relates to blocks used for forming retaining walls, retaining walls, or walls (hereinafter referred to as retaining walls, etc.) in civil engineering work, construction works, etc.
The present invention relates to a method for forming the manufacturing table Jv2, ljl wall, etc.

[Prior Art 1] Conventionally, many things related to this divine block have been disclosed, such as those described in Japanese Patent Publication No. 35762/1982, Japanese Patent Application Laid-open No. 137020/1997, and the like.

In addition, it is necessary to convert a naturally formed gentle slope into a negative slope (slope) that is human-friendly. is forming. Instead of using expensive natural stone (Machi stone), it is common to use concrete blocks (Machi blocks) for this formation, and a typical example is the one shown in Figure 7. be.

A feature of this block is that part of it has a tapered cross section that is gradually reduced in size, and this has the purpose of dispersing the approximately horizontal pressure exerted on the block by soil, pebbles, etc. Further, in the case of a block for forming a fence that requires dispersion of the pressure, this portion is formed flat.

By the way, when laying stones (blocks) for retaining walls etc. using these blocks for forming retaining walls, etc., use real silk to prevent the surface after masonry from becoming uneven or curved. (thread) is stretched, each side is aligned with the real silk, pebbles or split stones are placed between the blocks to determine the joint width, and the process is repeated.

Next, a retaining wall or the like is formed by filling the space between the joint widths with concrete or chestnut stone.

In addition, many of these blocks have various designs applied to their surfaces in response to customer requests, and this gives aesthetic treatment to retaining walls and the like, allowing them to blend in with the building.

[Problems to be Solved by the Invention] In the conventional blocks described above, the blocks do not engage with each other due to their shape, so retaining walls etc. formed using these blocks cannot withstand vibrations in the horizontal direction. What are you doing about the problems that it is unstable and fragile because it is not integrated with the foundation?

In addition, the masonry work is carried out jointly by one technician and 3 to 5 people in an auxiliary work room, which requires a special SM. ^ The problem that there is a difference in the quality of the finished product depending on the level of training was eliminated.

Therefore, the present invention aims to provide a method for forming a retaining wall, etc. that can be easily formed, is resistant to horizontal vibration, and is integrated with the foundation, a block used for forming the same, and a mold for manufacturing the same. purpose.

The reinforcing bars 13b are arranged in the direction α.

Thereafter, the methods for forming the second and third stages are alternately repeated.

Also, reinforcing bars in the first and second directions +2.13. It is formed by pouring concrete 14 into the space containing the .

When forming retaining walls and retaining walls, the blocks are stacked inwardly, and when building walls, the blocks are generally stacked vertically.

F Effects] The present invention is configured as described above, and provides the following effects.

■Since each block engages with its convex and concave parts, it is less affected by vibrations, and since the reinforcing bars connect vertically and horizontally within the retaining wall, etc., and the space is fixed with concrete, it is easy to interact with each other. A strong retaining wall etc. can be formed.

■Since the manufacturing mold for the block is composed of a plurality of assembled members, the block can be easily taken out after manufacturing.

- Since the blocks are stacked up by engaging the convex portions and the concave portions, retaining walls etc. can be formed without requiring special skill for tasks such as face matching and setting of joints.
