Abstract

(57) [Abstract] [Problem] To prevent injuries due to construction when constructing a retaining wall by constructing a retaining wall block, and to further improve construction efficiency. SOLUTION: In a block of a type in which a convex part 2 provided at a lower part of one surface is sequentially assembled on a retaining wall of a predetermined height while being engaged with a lower block, the block is held by hands on both lower parts on both sides in a direction perpendicular to the convex part 2. For providing a concave portion 3.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a small retaining wall block for constructing a retaining wall.

[0002]

[Prior art]

 Conventional retaining wall blocks for earth retaining are piled up on four sides in close contact. The back of the stacked retaining walls is filled with ready-mixed concrete depending on the height, but even if the post-cast concrete is sufficiently cast in, the block will protrude over a long time and the block will protrude to the front and collapse. There are often.

[0003] In addition, the recent upper and lower surface parallel type retaining wall blocks are both heavy and have poor workability in stacking. In addition, it takes a little time to move the blocks when constructing the blocks, resulting in poor efficiency. There is a risk that the installer will pinch a finger and cause serious injury.

[0004] Therefore, small retaining wall blocks have aesthetic appearance in stacking, and since there are many places where construction sites are narrow, there is a great demand for small retaining wall blocks because of good workability. However, stacking is often performed manually, and fine adjustments often rely on humans, even if they are mechanized. For this reason, it is necessary to design a small retaining wall block that is heavy enough to be lifted by hand, and that has a structure that facilitates construction and makes it difficult to pinch fingers.

[0005]

[Means for Solving the Problems]

 The purpose of this invention is to provide a small retaining wall block structure to prevent injuries during construction and to further improve construction efficiency.

[0006]

[Means for Solving the Problems]

 The present invention relates to a block of a type in which a projection provided at a lower portion of one surface is engaged with a lower block and sequentially assembled on a retaining wall having a predetermined height, and is held by hands at lower portions on both side surfaces in a direction perpendicular to the projection. The retaining wall block is provided with a recess for the retaining wall.

[0007] Protrusions are provided at the lower part of one surface to prevent each block from shifting forward of the retaining wall, and to be held by hands at lower parts on both side surfaces in a direction perpendicular to the convex parts. By installing the finger, the fingertips will not enter this recess during construction, and even if placed incorrectly, the fingers will not be pinched and serious injuries will not occur. Also, since the fingers are sufficiently caught, the blocks can be easily lifted, and the construction efficiency can be improved.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a hexahedral view showing an example of the shape, (a) a plan view, (b) a bottom view, (c) a front view, (d) a rear view, (e) a left side view, and (f). It is a right side view. In this example, a split surface 1 is provided at the front. In other words, at the time of molding, two blocks of the present invention are integrally molded in a continuous form facing each other, and after molding, the blocks are crushed at the center to reveal the natural laid surface on the surface. As can be seen from the plan view, the overall planar shape is almost trapezoidal, and a projection 2 is formed at the lower rear end. The lower part of both side surfaces is formed with a concave part 3 for inserting a finger when holding it.

[0010] The first stage of such a block is placed on the foundation 4 as shown in the construction example of FIG. Next, the second-stage block is mounted thereon by engaging the first-stage block with the rear convex portion 2. In each case, the fingers are inserted into the recess 3 and lifted, and the work is performed manually. The appropriate number of steps will be combined and the backing will be lined with concrete material 5 to complete the retaining wall.

Although the above embodiment is of the split type, it may of course be of the flat type or the fixed pattern type.

[0012]

[Effect of the invention]

 The retaining wall block of this invention can prevent obstacles during construction and improve construction efficiency.
