Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking block and a low-rise sound insulating wall.

[0002]

2. Description of the Related Art A low-rise sound insulation wall installed along a general road in an urban area has been attracting attention as a measure capable of taking measures against noise while avoiding sunshine obstruction, radio interference, or landscape destruction. FIG. 8 shows an example of this low-rise sound insulation wall 100, which is provided between a sidewalk 101 and a roadway 102 and has a sidewalk 1.
On the 01 side, a flower bed 103 is provided so as to be close to the low-layer sound insulation wall 100. In most cases, such a low-rise sound insulation wall 100 was constructed on site.
That is, if this construction situation is briefly described, the sidewalk 10
At the site to be installed along the roadway 102 on one side of the site, a foundation is put together with reinforcing bars, and a form panel such as a control panel is erected around the reinforcing bars to assemble the formwork, and concrete is poured into the formwork. Then, after the concrete has hardened to some extent, the formwork is removed, and if necessary, the wall or the like facing the roadway 102 is surface-decorated with tiles or bricks.

[0003] Instead of such construction on site, it has been considered to manufacture the low-rise sound insulating wall 100 by brickwork.

[0004]

When the low-rise sound insulation wall 100 is manufactured by on-site construction, as easily imagined, the construction is troublesome and requires a long construction period. On the other hand, if the low-rise sound insulation wall 100 is manufactured by brickwork, it is difficult to manufacture a sound insulation wall 100 having a wall strength strong enough to withstand an impact (horizontal force) in a case where a car collides in a traffic accident or the like. There is a problem that there is. Therefore, it was not suitable for installation along a roadway.

As described above, there is a problem in the construction method and construction in any of the conventional cases. The present invention has been made in view of the above circumstances, and has a sufficiently high wall strength with respect to horizontal force, and a stacked block and a low-rise sound insulating wall constructed using the block, which can be easily constructed. The purpose is to provide.

[0006]

In order to achieve the above object, the present invention takes the following measures. That is, the block for stacking according to the present invention is a flat frame type having a predetermined height, and a space formed inside the frame penetrates between the frame end surfaces on both sides (height direction). And, in this block, apart from the space inside the above-mentioned frame,
A support hole penetrating between the end faces of the frames on both sides is provided.

[0007] It is preferable to provide positioning concavo-convex having a relative fitting relationship on both end surfaces of the frame. That is, a convex portion is provided on one frame end surface and a concave portion is provided on the other frame end surface, and when a plurality of blocks are stacked, these convex portions and concave portions are fitted to each other. Thus, the upper and lower blocks can be positioned in a predetermined manner. In the stacking blocks having these configurations, if a plurality of the blocks are stacked, the support holes of the blocks are inevitably connected. Therefore, by inserting the strut into the strut hole in the communicating state, each of the stacked blocks has high wall strength against horizontal force.

[0008] Therefore, the stacked blocks can sufficiently withstand the impact in the event of an automobile collision. The above-mentioned positioning unevenness is provided as much as possible. For example, in the block used at the top of the stacking, in order to improve the appearance of the frame end surface which is the upper side in the stacked state, such positioning is performed. It is also possible not to provide the projections and depressions. In the case where the peripheral wall forms a square frame, it is preferable to arrange the positioning unevenness and the support hole so as to correspond to the corners of the square frame.

That is, the corners of the square frame are higher in strength than the other parts in terms of strength, but it is necessary to provide positioning unevenness and support holes in the corners. This leads to having more material volume around the corners, and as a result, increasing the strength of the peripheral wall as well as the positioning irregularities and the opening peripheral portion of the support hole. On the other hand, in the low-layer sound insulating wall according to the present invention, a plurality of the above-described stacking blocks are stacked on each other, and a space and a support hole of each block are mutually communicated in the vertical direction. On the other hand, a partition portion is provided upright above the uppermost block, with a support protruding from the support hole in the vertical communication state as a support.

It is assumed that the column has a length such that it can penetrate the entire height of the base frame (all blocks stacked) and further project upward. With such a configuration, the pillars that support the partition are
Since it is erected through the inside of the peripheral wall of the base frame (peripheral wall of each block), its standing strength is backed up through the base frame. Accordingly, the wall strength of the partition portion is also high.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of a low-rise sound insulating wall 1 according to the present invention. The low-rise sound insulating wall 1 has a foundation frame 2 and a partition 3. Foundation frame 2
Is formed by stacking a plurality of stacking blocks 5 each having a rectangular frame shape (the number of stacking is four in the first embodiment). There are two types of blocks 5 used in this case, one for the top row (5A) and the other (5B).

Each of the blocks 5A and 5B may be made of concrete, ceramic, resin molded product or the like. FIG. 3 shows the uppermost block 5A. The block 5A has a pair of long side walls 6 and 7 and a pair of short side walls 8 and 9, and a space 10 formed inside a frame surrounded by the walls 6 to 9 has It penetrates in the height direction (the vertical direction in FIG. 1) of the block 5A. The frame end surfaces 11 on both sides are flat and parallel to each other.

Further, at each of the four corners of the frame, a space 1 is provided.
Corner reinforcing columns 13 extending in the height direction are provided so as to bulge into a quarter circle into 0. Of these corner reinforcing columns 13, they are positioned at both ends of one long side wall 6. The support hole 14 is provided in the frame to penetrate between the frame end faces 11 on both sides. That is, this support hole 13
Is a hole penetrating the inside of the peripheral wall of the block 5 in the height direction as an independent hole separate from the space 10. FIG. 4 shows a block 5B used in a portion other than the top row.

This block 5B is also basically the same as the above-described uppermost block 5A, and has a pair of long side walls 6, 7 and a pair of short side walls 8, 9, Space 1
0 penetrates in the height direction, and corner reinforcing columns 13 are provided at the four corners.
Are provided in the corner reinforcing pillars 13 positioned at both ends of one of the long side walls 6, and pillar holes 14 penetrating between the frame end faces 11 on both sides are provided. The support hole 14 of the block 5A for the uppermost step and the support hole 14 of the block 5B used in a part other than the uppermost step have the same coordinate position in the frame end surface 11 and the same hole diameter. .

FIG. 5 shows a state in which the uppermost block 5A and the blocks 5B other than the uppermost block are stacked. As is apparent from FIG. 5, the block 5B used in a portion other than the uppermost portion is convex in a manner that the opening peripheral portion of the support hole 14 is raised with respect to the frame end surface 11 (11a) shown on the upper side in the drawing. A frame end face 11 (11b) shown on the lower side in the figure while a portion 16 is provided
The recess 1 is formed by recessing the periphery of the opening of the support hole 14 with respect to

The convex portion 16 and the concave portion 17 have a relative fitting relationship. Also, in the uppermost block 5A, the frame end surface 11 shown on the lower side in the figure is used.
A recess 17 is provided in (11b) by recessing the periphery of the opening of the support hole 14. However, with respect to the frame end surface 11 (11a) shown on the upper side in the figure, the opening peripheral portion of the support hole 14 remains flat (the convex portion 16 is not provided). These convex portions 16 and concave portions 17 are irregularities for positioning, and include a plurality of blocks 5 (5A, 5A).
When the blocks 5B) are stacked, the upper and lower blocks 5 (5A, 5B) are aligned vertically in the vertical direction and work so as not to be displaced by fitting each other between the blocks 5. Become.

Needless to say, at this time, the space 10 and the support hole 14 of each block 5 also communicate with each other in the vertical direction. On the other hand, as shown in FIG.
Is the pillar hole 1 in the vertical communication state in the base frame 2

It has a barrier 21 provided between them with 0 as a support. The column 20 is made of aluminum, stainless steel, steel or the like and appropriately subjected to rust prevention treatment.
And has a length such that it can penetrate the entire height of the base frame 2 (all the blocks 5 stacked) and project further upward.

It should be noted that the length may have some allowance so that it can protrude somewhat below the base frame 2 and also function as an underground pile. In the first embodiment, the column 20 has a square cross section, but may have a circular shape or the like, and may have a hollow (pipe) structure or a solid structure. The support 20 is provided with the uppermost block 5 in a state of being protruded into the support hole 14 which is in a vertically communicating state with the base frame 2.
A bracket 23 projecting laterally is attached to a portion projecting upward from A by welding or the like.

A mounting hole 24 is provided in the bracket portion 23. The barrier 21 is formed of a wooden board, a porcelain board, a cement board, a metal board, a resin board, or the like, and has a horizontally long plate shape extending between the two pillars 20. A vertical groove 27 is formed to penetrate the center vertically and allow the support column 20 to be inserted into the bracket portion 23. In addition,
In the illustrated example, a horizontally long plate-like barrier 21 is illustrated, but a vertically long plate-like barrier may be provided between the columns 20.

Then, in a direction crossing the vertical groove 27,
A through hole 28 is formed that can match the mounting hole 24 provided in the bracket portion 23 of the column 20. As is clear from the above description, in order to construct the low-rise sound insulating wall 1 having the above configuration, first, the blocks 5 (5
An appropriate number of B) are stacked one on another while fitting the positioning irregularities 16 and 17 to each other, and the uppermost block 5
The base frame 2 is assembled by stacking (5A). At this time, mortar or the like may be applied as an adhesive between the frame end surfaces 11 of the blocks 5 and fixed (wet construction), or only the blocks 5 may be fitted (dry construction). Construction).

Then, the two pillar holes 14 which are vertically communicated with the base frame 2 are respectively inserted into the two pillar holes 14.
The support 20 is fixed vertically by filling the gap formed between the support hole 14 and the support 20 with a mortar or the like as needed. Then, the vertical grooves 27 on both sides of the barrier 21
Is inserted into the bracket portion 23 of each of the columns 20, and the barrier 21 is held between the columns 20. Then, screws, nails, rivets, or the like are inserted from the through hole 28 toward the mounting hole 24 to insert the column 20 into the bracket 20. And the barrier 21 are fixed.

The low-layer sound insulation wall 1 can be obtained with only this operation. In the low-layer sound insulating wall 1 configured as described above, the columns 20 penetrate between the stacked blocks 5, and since the partitions 2 are provided with the columns 20 as supports, the low-layer sound insulating wall 1 as a whole is formed. Also, each part of the base frame 2 and the partition part 3 has high wall strength against horizontal force. Therefore, it is possible to sufficiently withstand the impact in the case where the automobile collides. In the base frame 2, the space 10 of each block 5
The part formed by communicating in the vertical direction may be planted by burrowing or filled with ornamental stones.
