Description

[Detailed description of the invention] [Field of industrial application] The present invention is a curved fence board made of concrete blocks that is used to form fences on mountainside slopes, fences on long slopes on slopes, and other slope protection fences. It is related to.

[Conventional technology]

Conventional methods for retaining earth on slopes include installing cast-in-place concrete retaining walls or retaining walls made of concrete blocks in stages to form retaining walls, and planting trees on stairways.

[Problems that the invention aims to solve] However, conventional retaining walls for slopes are unstable because each staircase is separated vertically, and the foundation of the retaining wall is also too strong. Since it was necessary to construct a concrete structure, the various materials necessary for construction had to be transported to the site, which required a lot of labor and time and was extremely uneconomical.

In view of these difficulties, it is an object of the present invention to provide an effective and appropriate curved fence board that allows construction of fences on slopes and the like with relative ease.

[Means to solve the problem]

The structure of the present invention, which was made to solve the above problems, is that a sleeve wing section has connecting vault through holes parallel to the central axis of the convex wall and laterally oriented on both left and right sides of the convex wall that protrudes on the front side. A block A is formed by integrally forming a trapezoidal base with a vertically oriented circular through hole formed on the back surface of the convex wall, and a block A that is parallel to the central axis of the concave wall on both left and right sides of the concave wall whose front side is recessed. A block B is formed by integrally forming a trapezoidal base having a sleeve wing portion in which a through hole for a connecting vault is formed in a horizontal direction, and a vertical circular hole with a bottom is formed in the back side of the concave wall. Blocks A and B are placed alternately in the vertical direction, and the placed blocks A and B are connected to each other by vaults in the horizontal direction and by mortar or concrete with reinforcing bars inserted in the vertical direction. It is characterized by:

[Effect]

It is composed of a combination of block A with a convex wall structure and block B with a concave wall structure, and each of the blocks A and B is connected to each other in the vault passage hole provided in the wing part of these face walls. Both wing parts are alternately connected with vaults, and convex wall blocks A connected to concave wall blocks B on both sides are alternately connected to convex wall blocks B on both sides. It will be placed.

In addition, the stepped portion having a bottomed hole on the back surface of the concave wall block B and the stepped portion having a through circular hole on the back surface of the convex wall block A are engaged with each other in a vertically opposed manner, and reinforcing bars are inserted into the respective opposing holes. Set it upright and pour mortar or fresh concrete to firmly connect the upper and lower concave and convex wall blocks A and B.

As a result, the entire slope is connected in a net-like manner by the concave and convex wall blocks A and B.
