Description

[Detailed description of the invention] The present invention relates to a block useful as a variety of general earth retaining walls, and in particular, a frontage block and a depth block are assembled in the shape of a parallel cross, and cracked stones and crushed stones are installed inside the block. This relates to a retaining wall block that is constructed by filling it with etc.

<Prior Art> Two types of retaining wall blocks of this type are known based on the structure of their assembly and engagement portions.

One type is such that the uneven engaging parts of the frontage block and depth block are stacked and engaged, and the other type is such that each stacked frontage block and depth block have connecting reinforcing bar insertion holes. The blocks are opened in a corresponding manner, and each block is connected by inserting a separately prepared reinforcing bar, for example, in the shape of a round bar, into the insertion hole.

However, since the former is simply stacking each block, there is a risk that the assembled state may lack stability, and the latter requires long reinforcing bars to be inserted into the reinforcing bar insertion holes formed in each block when the blocks are stacked. It is necessary to perform stacking work while
Therefore, there was a risk that workability would deteriorate.

<Problems to be solved by the invention> The invention provides a retaining wall block that can be easily assembled and loaded without complicating the shape of each block itself, and in which the assembled state can be stabilized. This is what I am trying to do.

<Means for Solving the Problems> The retaining wall block of the present invention consists of a frontage block and a depth block. The frontage direction block has a prismatic narrow diameter part at both ends in the length direction of the main body with the upper and lower edges in the length direction as overlapping parts, and the end face of this narrow diameter part is adjacent to each other in the length direction. The frontage blocks are arranged in series sequentially in the length direction, and are used as abutting surfaces with the tip surfaces of the narrow diameter portions of other frontage blocks to be provided. Also,
The depth direction block has flange portions on both front and rear end surfaces thereof that extend in the vertical direction and engage with the front surfaces of the adjacent narrow diameter portions. A steel bar is provided on either the upper and lower surfaces of the narrow diameter portion of the width direction block or the upper and lower surfaces of the flange portion of the depth direction block, and a fitting hole into which the steel bar is fitted is provided on the other side in the vertical direction. This steel bar is fitted into the fitting portion, and the frontage block and the depth block are stacked and assembled.

<Operation of the present invention> In the present invention, the steel bar provided on either the narrow diameter portion of the frontage direction block or the flange portion of the depth direction block is fitted and inserted into the fitting hole provided on the other side. Since each block is loaded and assembled in this state, the assembly state between each block is extremely stable, and the steel bar is integrally fixed to either the frontage block or the depth direction block. The fitting and locking of the steel bar and the fitting hole can be realized simply by vertically overlapping the fitting hole provided in the other block on the steel bar.

<Example> Next, an example of the present invention will be described with reference to the illustrated example.

First, an example of the frontage block 1 according to the present invention will be explained with reference to FIGS. 1 to 5.

In this example, the frontage block 1 has a main body 11 with flat overlapping surfaces 11 on both upper and lower sides in the longitudinal direction.
a and 11b are formed parallel to each other. Each of these surfaces 11a and 11b serves as a butting surface when other frontage blocks 1 are stacked one on top of the other in the vertical direction. Further, in this example, the front surface 11c of the main body 11 is bulged in a semicircular shape and has a semicylindrical shape as a whole. Furthermore, rectangular prism-shaped narrow diameter portions 12 and 13 are integrally provided at both longitudinal ends of the main body 11, respectively. Each tip surface 12a, 13a of this narrow diameter part 12, 13
are the similar end surfaces 12 of other frontage blocks 1 when the other frontage blocks 1 are arranged in parallel in the left-right direction.
This is the part that becomes the mating surface with a or 13a.
Further, the front surfaces 12b, 13 of the narrow diameter portions 12, 13
b is a portion that becomes an engagement surface with a flange portion of the depth block 2, which will be described later.

Furthermore, upper and lower surfaces 12 of the narrow diameter portions 12 and 13
c, 12d and 13c, 13d are the overlapping surfaces of the depth block 2, which will also be described later.
A steel bar 14 is fixedly protruding from the center of each of these surfaces 12c, 12d and 13c, 13d. That is, this steel bar 14 is firmly fixed to the frontage block 1. And this steel bar 14
are for fitting and locking into fitting holes formed in depth blocks 2, which will be described later, which are disposed above and below this frontage block 1. In addition, the above steel bar 14
The length of the steel bar 14 protruding from the surfaces 12c, 12d and 13c, 13d is
The length is such that it fits within the middle of the fitting hole. In the illustrated example, the steel bar 14 is formed to have approximately the same size and length as the width in the height direction of the main body 11 of the frontage block 1.

Note that the main body 11 portion of the block 1 and the back side of each of the narrow diameter portions 12 and 13 are flush with each other, and the entire body forms the same plane.

Next, an example of the depth block 2 according to the present invention will be explained with reference to FIGS. 6 to 9.

In this example, both upper and lower side surfaces 21a, 2 of the main body 21 are
1b are formed into parallel flat surfaces. Further, wide portions 22 and 23 are formed on both left and right side surfaces near the front end and the rear end, and extend in the left-right direction. The wide portions 22 and 23 are connected to each other when the frontage blocks 1 are arranged in parallel.
The upper and lower surfaces 12c, 1 of the adjacent narrow diameter portions 12, 12
This is the overlapping portion of 2d, 13c, and 13d. Furthermore, flange portions 22a, 22b and 23a, 23b are projected in the vertical direction from the front end and rear end surfaces of each of the wide portions 22, 23, respectively, in an L-shape.
d and 13d are configured.

Furthermore, fitting holes 24 for the steel bars 14 distributed in the left-right direction are formed through the wide portions 22 and 23 in the vertical direction.

Next, the above-mentioned frontage block 1 and depth block 2
The state of assembling a retaining wall using a large number of pieces will be explained with reference to FIGS. 10 and 11.

First, add depth block 2 to each block 2 at the bottom.
are located in the front-rear direction, and are arranged in parallel with the distance between each block 2 maintained equal to the length of the frontage block 1. Then, the frontage blocks 1 are assembled from above along the front and rear ends of each of these depth blocks 2 so as to be stacked on top of each other.

That is, each steel bar 14 protruding downward from both ends of the frontage block 1 is fitted into the fitting hole 24 of one of the adjacent blocks 2 of the depth block 2, and in this way the frontage blocks 1 are successively adjacent in the length direction. Arrange and assemble as shown.

Then, a second depth block 2 is assembled to the upper stage of the frontage block 1 so that its fitting hole 24 is fitted with the steel bar protruding above the frontage block 1.

This state is the state shown in FIG.

When the frontage block 1 and the depth block 2 are sequentially stacked and assembled as described above, a retaining wall is assembled from these blocks 1 and 2 as shown in FIG. 11. Therefore, the retaining wall is completed by filling the inside of each of the blocks 1 and 2 assembled in a cross-shaped structure with cracked stones, crushed stones 25, etc.

Next, another embodiment of the present invention will be described with reference to FIGS. 12 to 22.

In this embodiment, a fitting hole is provided on the frontage block side as shown in FIGS. 12 to 16, and a fitting hole in the width block is provided on the depth block side as shown in FIGS. 17 to 20. A steel bar is provided that fits and assembles the two.

That is, the frontage block 3 has substantially the same shape as the frontage block 1 of the first embodiment, except that the upper and lower sides of the rectangular prism-shaped narrow diameter portions 32 and 33 provided at both ends of the main body 31 in the longitudinal direction are A fitting hole 34 is formed in which a steel bar 44 of the depth block 4, which will be described later, is fitted instead of the steel bar 14.

The depth block 4 also has approximately the same shape as the depth block 2 of the first embodiment, but the wide portions 42 and 43 projecting in the left-right direction on both left and right sides have a fitting hole 24 on the upper and lower surfaces thereof. A steel bar 44 that is fitted into the fitting hole 34 of the frontage block 3 is provided.

Therefore, as shown in FIG. 21, the depth blocks 4 are arranged in parallel while holding the length of the frontage blocks 3, and the frontage blocks 3 are extended from above along the front and rear ends of each of these depth blocks 4. It is assembled so that the fitting hole 34 fits into the steel bar 44 of the block 4. Then, the frontage blocks 3 and the depth blocks 4 are sequentially assembled in a parallel grid pattern, and as shown in FIG. 22, the inside of each block 3, 4 is filled with cracked stones, crushed stones, etc.

<Effects of the present invention> In the present invention, between the frontage direction block and the depth direction block, a steel bar provided on either the narrow diameter part of the frontage direction block or the flange part of the depth direction block is provided on the other block. The blocks can be assembled accurately by sequentially fitting them into the provided fitting holes, and furthermore, the assembled state between the blocks is extremely stable due to these fittings.

Moreover, since the above-mentioned steel bar is integrally fixed in advance to one of the frontage direction block and the depth direction block, it is only necessary to assemble each of the two types of blocks, the other block having a fitting hole for fitting this steel bar. Because it is good, it has excellent workability.
