Abstract

PURPOSE:To construct a strong retaining wall by stacking up various kinds of blocks having triangular jointing ends in a staggering form. CONSTITUTION:Root blocks A having inversed triangular jointing ends, base blocks B having angular jointing ends, and top blocks C having inversed triangular jointing ends are stacked up. In this case, the length of the stay hip part (for block A) of each block is maximized and the length of upper blocks (for block B) is minimized. A strong retaining wall in which the angularly sloped whole surfaces of the blocks are engaged with each other can thus be constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete block stacking method for constructing retaining walls at protruding corners for roads, rivers, residential land development, and other areas.

Conventionally, this type of stacked block is generally constructed by stacking blocks with the same retaining length and a thin retaining body by stacking them by area or volume, and filling the space of the narrow retaining body with concrete to construct a retaining wall. did. When stacking these blocks with triangular side surfaces formed with a narrow backing part, the blocks are lined up in parallel with their surfaces aligned using Shirikai fodder stones at the backing end, and a back plate is placed on the backing end to form a thin backing part. The space was filled with concrete.

Then, this process was repeated, and the walls were lined up horizontally and filled with concrete layer by layer to construct a retaining wall for any memorial service.

As this type of filling with concrete for each stage takes time, the filling concrete in the lower stage and the concrete in the upper stage do not integrate and form a boundary.Furthermore, there are few joint ends of the blocks, and the soil water pressure from the back side is absorbed by the concrete. The presence of boundaries in the concrete causes the blocks to be pushed out by pressure, causing collapse. In addition, the stones placed at the end of the pile are easy to move, and even if they are lined up in parallel, they often have to be moved and reworked when filling with concrete, which often takes two or three times. The block construction method of the present invention eliminates the above-mentioned conventional drawbacks.In constructing a retaining wall using stacked blocks, the strength of the retaining wall is determined by how the root blocks (root stones) are placed and the shape of the blocks. This was developed based on many years of experience and results, and provides a new block construction method.

In the stacked blocks used in the present invention, the entire chevron-shaped joint surface from the surface to the butt end is the joint end, and the blocks with different lengths of the backing lengths are stacked in order from the longest block, and the left and right sides are staggered up and down. Hole grooves (5) and (6) are formed in the center and both sides of the mountain shape of the block to form vertically penetrating holes (5) and (6), which are stacked alternately and mesh with each other on the mountain-shaped inclined surface.
5).

(6) is a through hole that reaches the foundation ground, and the reinforcing steel (7) and poured concrete (8) are filled from above to the foundation ground, and the entire block is constructed by stacking it from the foundation ground, and the retaining wall is constructed by integrating the entire block. The entire surface of the mountain-shaped slope of the stacking joint surface engages, and by inserting reinforcing bars through the through holes from above and filling with concrete, the back side of the butt end is stacked in a stepped manner, making it sturdy by supporting the soil water pressure from the back side. Build a retaining wall. Similarly, the decorative surface of the block serving as the front surface is shown flat for clarity of illustration, but it can be formed into an appropriate shape such as an uneven surface or a randomly uneven surface.

Next, an example of a block and stacking method for carrying out the present invention will be described with reference to the drawings. Figure 1 shows the root block A installed on the foundation ground, (a) is the front view, (b) is the ridge side, and 0 is the plan view. This is the most important block because the bottom is flat and the center of the top is an inverted triangular valley with a joint (1
), and a hole (5) that passes vertically through the center and grooves (6) that pass vertically on both sides are formed, and the retaining length is made longer than the basic block B to be stacked on the upper stage.

Figure 2 shows the second basic block B to be stacked on top of the root block A in the first figure. At the end (2)
It consists of a top and bottom through hole (5
) are formed with vertical grooves (6) on both sides. The restraint benches are formed to be shorter than the root blocks, and the restraint benches of block B are successively shortened and stacked one by one. Blocks B of this shape are used the most, so they are prepared by appropriately adjusting the backing dimensions depending on the number of stacking stages during block molding, and are stacked in a stepwise manner during construction.

Figure 3 shows corner block A' installed at the corner of root block A. (A) is the front view, (B) is the side view, and C→ is the plan view. Make it the same length as root block A. In the illustration, the block is on the right, but there are also blocks facing the opposite direction.

Figure 4 shows side block B', which is a chevron-shaped half-cut of basic block B.
Ashi (a) is the front, (b) is the side, ? → is a plan view, and like the corner block in Fig. 3, upper and lower through grooves (6) are formed on both sides, and the length of the retainer varies depending on the stacking, similar to the basic block. This side block is a block that uses either the left side or the right side depending on the length of the retaining wall.

Figure 5 shows the top block C used for the top. (A) is the front view, (B) is the side view, and (C) is the plan view. The top end block has an inverted triangular mating end (3) to be fitted, and a top and bottom through hole (5) is formed in the center, and a top and bottom through hole is formed on both sides. The height of the retaining wall is adjusted using this top block C, and the height of the basic block Bol is adjusted from the root block A using the top block of the length lever, and the retaining length of this top block C is Make it shorter than the top block of the stacked basic blocks B.

Figure 6 shows the top corner blocks C' stacked on the left and right sides of the top block in Figure 5. (a) is the front view, (b) is the side view, and e is the plan view, with upper and lower through grooves (6) formed on both sides. do. This corner block has the same height and length as the top block C in FIG.

Figure 7 is a front view of an embodiment of the stacking method constructed using the concrete blocks of the present invention, where the bottom of the root block A is installed parallel to the foundation ground GK, and the root corner blocks A are installed at both corners due to the length of the retaining wall. ′ is placed.

Embed the bottom of root block A with concrete and fix it to the foundation ground aJtc. In this way, the chevron-shaped joint (
1) Insert the Taniyasha edge (2) of K basic block B, and use basic block B to pull the halves of both plate blocks A and A together according to the inclination angle of the joint ends, stack them, and arrange them arbitrarily. do.

Then, half-cut side blocks W are stacked on the side of the retaining wall length K at the right end or left end using a stacking stage.

Next, for the second stage of paralleling, stack the mountain-shaped joint ends (2) of block B on the upper surface valley-like joint ends (2) of the first stage parallel to the valley-like joint ends with the mountain-shaped joint ends (2) facing downward, and cut the retaining walls in parallel. In the same way as the first row, stack the half-cut side broncs on the side. Repeat this staggered stacking process to construct a retaining wall of arbitrary length, and place the top of the top basic block B at the valley-like end with the plane facing up and the chevron-like end (3) facing downward. Then, the top block C is stacked, and both corner blocks C' are stacked at the left or right corner of the top, and the block stacking is completed.

The most important thing in this stacking method is to lengthen the support lengths of the root blocks A and A' embedded in the foundation ground G and gradually move upward from the basic blocks B and B' to the top block C1C'. By stacking stacked blocks with short lengths, and stacking the stacked blocks from the bottom in a step-like manner, the reaction force against soil water pressure from the back side is increased, stabilizing the retaining wall, and reinforcing steel ( 7) and through-holes (5) from the top surface to the foundation ground where concrete is to be poured (6), and fill with concrete (8) to integrate the stacked blocks from the bottom to the top block.

FIG. 8 is a side view of an example of stacking using the stacked blocks of the present invention, in which the front side is vertically stacked and the back side is a stair stack.

FIG. 9 is a side view of a ridge of the present invention, which is an example of stacking blocks using dipping blocks, which is stacked on a slope and has a stepped back surface.

In the present invention, a step-like stacking method has been described, but it is also possible to stack the front side in a step-like manner.

In the block construction method of the present invention, the bottom surface of the root block A is installed on the foundation ground G with a large ground surface to stabilize the constructed retaining wall.
The retaining length of this root block is gradually shortened from the bottom to the top from the root block to form a retaining wall that is thinner at the top and thicker at the bottom when viewed from the side, which provides a reaction force against soil water pressure from the back side. The joint surfaces are supported and stacked from the mountain-shaped or valley-shaped surfaces to the butt ends, which increases the frictional force at the engaging ends of the inclined angle, and eliminates the need for conventional concrete inserts once the top, bottom, left, and right sides engage with each other. The structural retaining wall according to the present invention, which is stacked strongly without any slight movement even when it is empty, and which integrates the foundation ground and stacked blocks by inserting reinforcing bars through through holes that reach the foundation ground from above and filling it with concrete, can be damaged by earthquakes and floods. This is a stacking method that uses rational stacked blocks that exhibit durability in the event of disasters, such as stacked blocks that mesh with each other at an inclined angle, and that becomes increasingly stronger, and has the revolutionary effect described above.

In addition, the stacking method of this stacked block is square, rectangular,
Even if stacked blocks have the same surface shape, such as a hexagon, from the top to the bottom, blocks with different side lengths that thicken from top to bottom can be stacked in a stair-like manner (reinforced or concrete can be used as needed). Forming an injection hole) It goes without saying that strengthening the retaining wall by supporting earth water pressure from the back side is within the scope of the present invention.

As mentioned above, in the construction method of the present invention, the block shapes form a joint surface with an inclined angle toward the center and are stacked together as joint ends.
When stacking, the top, bottom, left and right sides interlock with each other at an angle in a staggered manner, increasing the number of stacked joint surfaces and increasing the frictional force. The stacked retaining walls are easy to stack by simply stacking them in the opposite direction, and by inserting reinforcing bars that penetrate from the top to the bottom foundation ground and filling the walls with concrete, the blocks are stacked as if they had been driven into piles, and the blocks are fixed together. The back surface is stacked thickly at the bottom and thinly at the top in the form of a staircase that provides sufficient support against soil water pressure. Therefore, we believe that the retaining wall structure according to the construction method of the present invention in preparation for disasters is a theoretical stacking method of stacked blocks that has never been seen before.

In particular, in recent years, when stacking is often carried out using heavy machinery such as cranes, if the stacking blocks of the present invention are made larger and the construction is carried out, labor costs and stacking become easier, shortening the construction period and lateral construction costs. This eliminates the need for rework, and eliminates the need for rework, as there is no need for parallel construction with the conventional parallel construction of each tier with a truss butt, and there is no slight movement even when stacked in several tiers. This is a time-saving block construction method that does not require any work such as filling or backing plates.
