Description

[Detailed Description of the Invention] The present invention relates to an improvement of a hollow concrete block capable of greening a slope, and in particular provides a block having a space at the rear that enables concrete longitudinal beams and stone tying. be.

First, the basic structure of the hollow concrete block to which the improvement of the present invention is applied will be described.

The basic structure of the hollow concrete block to which the modification of the present invention is to be carried out is shown in Figs. 1 to 27, although there are various design changes, but basically the structure is as shown in Figs. 1 to 3 and 8. As shown in FIG. It has a front wall part 5, and a back wall part 1 along the rear end between the side walls.
is constructed, a hollow is formed by the two side walls, the bottom plate, and the back wall, and the bottom plate has an inclination that is higher from the rear end toward the front wall. It is.

The side plate can be a flat plate, a curved plate, a bent plate, etc., and its shape can be a square, a diamond, a trapezoid, etc.

Further, along the front end of the side wall, there is a partition wall 6 extending laterally outward, and concrete is poured into the space outside the block formed by the partition wall 6 and the sides 4i 3 &t. The space where this concrete will be poured is side wall 3 and partition wall 6.
, τ111 It is formed by the protrusions 7 running vertically on the board and those of the adjacent blocks, but the parts other than the side walls can be replaced by on-site formwork. The substituted lifting platform is a partition wall,
The protrusion can also be omitted. The hollow chamber is filled with earth and sand, and the front wall is also filled with earth and sand, and vegetation grows here.

Openings 9, 10, and 11 are provided in the bottom plate, side walls, and back wall as necessary, and when this block is constructed as a retaining wall, the earth and sand in the hollow chamber, This promotes the flow of water and nutrients between the soil and sand in adjacent blocks, and helps extend the life of greening.The shape of the opening is square, circular, etc., as long as F<1. Alternatively, the opening in the back wall may be opened upward (as shown in Figures 16 to 18).

The hollow concrete blocks are designed to create a solid retaining wall, and the following design features are used to ensure the engagement between each block.

The second step is to strengthen the bond between concrete and blocks. Fourth
(As seen in (z), the concrete pouring space is extended from inside the block with 61 reinforcing bars.

In addition, the partition wall 6 is shifted downward by a small distance with respect to the side wall 1,
Create four parts on the top end and a convex part on the bottom end.

These concavo-convex portions fit into corresponding ones of vertically adjacent blocks. Of course, the basic form is to align the partition walls and side walls without shifting vertically, as shown by the dotted lines in FIG. This basic shape is necessary when assembly is easy depending on the topography, or when the slope of the retaining wall is steep.

M3,4.10 As shown in Figure 10, the lowest part of the bottom plate (
Rear end]K A protrusion 4 is provided in the lateral direction, and can be fitted and locked between the side plates of the blocks adjacent below. Also, depending on the weight of the block, it may not be provided.

If the lowest end of the bottom plate is connected to any position above the lower end of the wall 1 as shown in Figure 5, the protrusion 4 can be omitted, and the beam 8 may also be omitted. . Similarly, FIG. 6 shows a specific example in which the bottom plate is connected to the back wall at a medium pressure. This also shows a case where the bottom plate is bent in the middle and has a horizontal portion in the latter half.

In order to form the concrete blocks as described above using formwork, the shapes of the blocks have been devised. For example, in order to make it easier to remove the mold from the formwork, the thickness of the plate may be changed to give it a tapered shape, or the openings 9. I
The inner surface of Q and 11 is sloped, and the inner diameter is gradually increased or decreased.

In FIGS. 7 and 9, the side plate has a maximum thickness at the point where it intersects with the bottom plate, and the thickness decreases in a tapered manner toward the upper and lower ends.

The inner diameters of the apertures 11 in the back wall and the apertures 10 in the side plates change in a tapered manner, and the maximum and minimum diameters are located at either end of each aperture.

However, since the hole 9 in the bottom plate is formed by the curved part of the two upper and lower molds that sandwich the bottom plate, the smallest mold is located approximately in the middle with respect to the hole axis, and the diameter increases toward each end. In some cases, it has two tapered shapes, the side wall,
In some cases, the inner diameter and outer diameter are uniformly tapered, such as in the case of an opening in the back wall.

In addition, a protrusion 7 runs vertically on the rear half of the side plate, which strengthens the adhesion with the concrete that comes into contact with the side plate, and also serves to transmit stress from the soil applied to the block to the concrete. .

Further, the side walls 3 may be arranged substantially parallel to each other, or may be open or closed toward the front wall.

When constructing a retaining wall using blocks molded in this way, the lowermost stage is a deformed block, that is, a block whose bottom plate has increased thickness R1 and has a horizontal lower surface as shown in Figure 11. That is preferable. Figure 12 shows its front view, 4.
13 and 14 show cross-sectional views.

The blocks described above also include those in which the upper half of the back wall is cut out to form an opening, and the top surface of this block is shown in FIG. 15. FIG. 16 shows a longitudinal section taken along the center line, which also includes the case where there is no back wall portion.

The lower half of the block in FIG. 15 lacks a partition wall, and the upper half of FIG. 15 is a block with one attached.Depending on necessity, a partition wall may or may not be attached. Furthermore, the second
Shown in Figure 0-! As shown, the bottom plate extends rearward beyond the rear end of the side wall, and the back wall part is erected from the edge of the bottom plate, so that the back wall part and the back part are connected to each other.
It also includes a block forming an aperture between each of the two side walls.

If the space between the side walls is wide, install one or two back plates J between them so that the back plate J1 or more will not affect the hollow chamber.

Its plan view is shown by the dotted line in FIG. 15, and its AA cross section is shown by the dotted line in FIG. 16. The height of the back wall may be arbitrary, and a low back wall portion and a high back wall portion may be combined.

The position of the intersection between the bottom plate and the back wall can be any (+'r) in the vertical and horizontal directions, similar to the blocks in Figs.
-Put it down (・(Figure 17, Figure 181).

As shown in Fig. 1818, it is also possible to leave only the lower end part of the back wall and omit the entire upper part. Also, the back wall may be completely omitted.

There may also be a plurality of openings in the 1r wall in the trough shown in FIG. 19.

As shown in the lower half of No. 201, the partition wall 6 is removed and 1llll
The present invention also includes and compares a case a in which the l wall edge and the front wall edge almost coincide.

Further, as shown in FIG. 15, a low back wall portion may be provided along the edge of the protruding portion of the bottom plate.

Furthermore, the back wall portion 1 may be of a buttress type in order to be stronger. (Figure 20, chain line in Figure 6) Also, as seen in Figure 1, the protrusion 7 extends from the K O1'1 wall (l: j 1 in the shape of the valley explained above).
It not only includes the &1-Jr' block that is created by assembling each component of the block one by one. This includes the bending of the retaining wall and the 9
It is used as a combination of 4-chono-no-1boku.

Figure 2119 is a block with the partition wall 67' on one side and the 111th section of the front wall 5 cut off, ε1'. It was done [
The block shown in FIG. 25 is roughly halved. This irregularly shaped block is not limited to this block, but is
Su is also applied to the shape of the block described in J.

Furthermore, the shape of the bends of the bottom plate may include a straight-line shape (Fig. 25) or multiple bends, and the bends may be at arbitrary positions in the vertical and horizontal directions (Figs. 24 to 26). , the planar shape of this figure corresponds to the plan view of the above-mentioned figures (1st to 20th and 24th to 26th figures).

The structure and shape of the above-mentioned block of the present invention include a bottom plate 2K having a straight line and a bend and being horizontal or having a t or I slope, and a side wall 6 having an arbitrary shape such as a rectangle, a rhombus, a trapezoid, etc. as basic elements. It is a block body formed by combining one or more of the 11 block components of the design as necessary.

The present invention is not limited to locks 1!1 to 1 to 20, but is also applicable to blocks whose bottom plate and front wall are bent at arbitrary locations, as shown in FIGS. 24 to 26. It also includes shape.

As shown in FIG. 25, the bottom plate 2 and the front wall 5 are in a straight line and are parallel to the side wall at the lowest end of the side wall, but the present invention is not limited to the lowest end, but may be at any vertical position on the side wall. ·.or,
In this case, the opening part 10 is divided into two parts, upper and lower, but it is not limited to the upper and lower parts, it may be provided in either one, and may not be provided depending on necessity.

Although FIG. 24 shows the bending position of the bottom plate, the bending position is not limited to the side wall 3, but may also be on the front wall 5, and the bending position is not limited to one place but multiple places. There may be multiple locations. The bottom plate and the front wall may each have one or more bending points. As in Fig. 25, the position of the bottom plate and the position of the direction bending can be arbitrary in the vertical and horizontal directions.

In FIG. 26, as in FIGS. 24 and 25, the bending points, positions, and directions (inclinations) of the bottom plate and front wall may be extended or not extended.

Figure 1XZJf shows the most practical hollow concrete block. The bottom plate 2 is a flat plate from the rear end portion to the front wall portion 5, and extends obliquely upward.

An opening is provided at the center of the bottom plate, at the rear of the side wall, and at the center of the back wall. A concrete tJ space is constituted by a side plate 3, a projection 7 running vertically on the side plate, and a partition wall 6.

The adjacent block below is the protruding east 4 provided at the lower end of the back wall.
is fixed by inserting it between the side plates of the lower block.

A crosspiece support 12 is provided near one end of the opening in the side plate, and as shown in detail in FIGS. 43 and 44, this is a crosspiece that supports the formwork 16 that will form the rear wall of the concrete space on site. The receiver 15 is a recessed portion that functions to fix the device. These are fixed by being press-inserted into this recess together with the wedge 14.

Now, as stated at the beginning, the present invention relates to improvements to the above-described concrete blocks for middle beams, and the improvements of the present invention will be described below.

That is, the present invention is to provide a space at the rear or adjacent to the rear side of the back wall of a concrete block, into which concrete or chestnut stone can be filled, and by this improvement, the strength of one masonry wall can be increased. Alternatively, it is possible to improve drainage by using Awaishi. That is, the present invention basically consists of a hollow concrete block having two opposing side walls, a bottom plate installed between them, a front wall connected thereto, and a back wall at the rear. It is a hollow concrete block characterized by having a space between the sides for filling with concrete or chestnut stone.

Figures 28, 29, and 30 show Vi on the back wall of the block.
An example is shown in which nine rear chambers 21 are formed by making contact with each other. The rear nitrogen trap was formed using the 1111 board of II-1, 1, three 9111 boards, and two side boards as shown in Figures 28, 29, and 30, and the formwork was provided on site. 1) Fill it with concrete and act as a joint beam to support the back of the block. In this way, by making the rear space room a concrete vertical beam, the strength of the double lock 3tM wall is increased, and the basic shape of the block VC can be deformed. For example, the partition wall 6 may be omitted, the gap between the side plates may be widened toward the front as shown in Figure 29, or the front may be expanded by making one side wall cylindrical as shown in the upper half of Figure 30.
It also includes a block shaped like an iJL, or a block shaped like an opening at the rear as shown in the lower half.

This rear space chamber can be molded integrally with the block, but in order to facilitate molding, the basic block and the rear space chamber can also be molded separately and assembled on site as shown in FIG. 51. At this time, if a reinforcing bar is extended from the block, and the reinforcing bar is inserted into the opening 25 of the rear space chamber, and the concrete 7 is put into the rear space chamber, it becomes integrated with both blocks. The rear space chamber is not limited to concrete, but may also be made of construction materials such as wood, paper, plastic, etc.

The engagement with the lead becomes stronger.

Figures 52 and 33 show the entire rear chamber filled with chestnut stone to be used for vertical drainage. However, the cross-sectional shape may be arbitrary, such as a trapezoid or a semicircle, and the rear side is open to facilitate drainage of the ground. Also, concrete may be poured into blocks of this shape as described above (FIGS. 28 and 31). Also, when filling the rear space chamber with chestnut stone,
An aperture may be provided in the back wall. Figure 64 is A of Figure 36.
- Shows Al17i surface. In particular, the rear space chamber 21 for filling with chestnut stone is not limited to the position directly behind the back wall, but may be placed beside the back wall, that is, behind the concrete vertical beam between each block, as long as it has the same effect. FIG. 65 shows the shape of a block in which this rear space chamber can be provided.

Two spaces on both sides of the block formed by the partition wall 6 extending from the side plate 3 by external force and the side plate further back can be used as the rear space chamber 21. If chestnut stone is packed here, some dirt in the hollow chamber of the block may be sucked out towards the chestnut stone, so in such a case, it is recommended to close the opening 10. By using four plates 22 that extend further rearward and protrude from the side plates, the volume can be increased.

When the block of the present invention having the rear space chamber 21 filled with the above-mentioned stone is assembled, its plane is shown as shown in FIGS. 41 and 42. The rear space chamber is located on the back wall (both sides and sides are combined).The openings in the back wall and side panels are made on site.
You can freely design the installation and toke sushi depending on the ground conditions.

Figure 40 shows a longitudinal section of the masonry. In this case, the four rows from the bottom are blocks of the present invention, but the upper six rows are simple blocks (
(Figures 36 and 37) But yo (・.

Now, since the present invention has made it possible to construct JJmW with improved drainage or increased strength, there may be cases where it is not necessary to rely on the products of the present invention for all blocks in the retaining wall. For example, it is possible to arrange two of the above-mentioned blocks as shown in Fig. 36 side by side, omit the two middle side plates, and incorporate a block with a connected bottom plate.The back wall covers the entire back surface, Alternatively, one or more sheets may be placed in the center.

As shown by the solid line in Figure 37, 1! ! A projecting plate 22 may be provided at the rear of the wall so as to form the above-mentioned rear space chamber. Also, the rear space chamber is located inside the bottom plate as shown by the dotted line in the same figure.
It's okay to stay inside. At this time, Fukai 33 was a member of the association (・
Provided from It is possible to construct masonry by combining the shapes and sizes described above. Fig. 38 shows a diagram in which blocks with the shape shown in Fig. 2 are installed on each side of the Figure 2144o shows the 0 masonry P-J side view. Figure 42 shows the installation ζ plan view as a drainage-related installation diagram. Figures 46 and 44 show the four installation states of the formwork 16. I messed up the diagram.

Formwork 1 when pouring concrete after block masonry
When tightening the formwork for installing the block 6, it is convenient if there is a groove 12 in the block to hold the formwork.

After the formwork is installed, the crosspieces 15 are fitted into the fire support crosspieces 12, and the wedges 14 are further inserted to completely fix the crosspieces. The side surface of the crosspiece support is shown in FIG. 45, and the attached state of the formwork, crosspieces and wedges is shown in FIG. 44.

The block body of the present invention is formed with a shared front wall portion 5 (
・When stacked, it becomes step-like.

Therefore, in places where there are relatively many children, such as parks, the shelf 5 can be used as a playground, and climbing from the front wall can be considered dangerous. For this purpose, a construction method 2 in which a slope block 26 made of construction material such as concrete is placed on the soil 24 of the front wall, or a concrete rope is directly installed, and a clearing area 25 is opened only in the planting area.
If 6 is adopted, children's hands and feet will not be able to climb, so they will not be able to climb.

The plane of the slope block 26 is shown in FIG. 45, its perspective view is shown in FIG. 46, and its cross section is shown in FIG. 47.

In the structural explanation of the block described above (Fig. 1 to Fig. 44), the front wall part 5 was basically used, but the front wall part 5 was omitted in order to improve the aesthetic appearance of the block masonry state and to prevent the above-mentioned danger. The present invention also includes the structure of A perspective view thereof is shown in the right figure of FIG.

A slope block 26 is installed to prevent the hollow chamber 27, or a slope block 26 including the partition wall 6 is installed. The perspective view is l54s
Shown on the left side of the figure. In addition, one or more reinforcing bars 31 are arranged on the slope block 26, stretched out, and concrete 2 is placed on the slope block 26.
If it is fixed at 8, the flow will be reduced. The plan view is shown in Figure No. 49. The upper side is the slope block with the partition wall 6 added, and the lower side is the installation plan of the slope block b without it. In this case, the formwork 2-9- It can also be shaped by stroking if required. Its plane is shown in FIG. 51, and its cross section is not shown in FIG. 52. The number of openings in the bottom plate may be as large as 1 or 2 or more at any temperature, but it is convenient for management if there is a hole on the slope block side in case of earth and sand flowing out after masonry.

Further, when the chestnut stone 17 is placed in the aforementioned rear space chamber 21, construction may be difficult depending on the geological condition of the masonry, so it is convenient to extend the back wall portion 1 and provide the protrusion 7. Depending on the condition of the spring water, an appropriate opening section 25 may be provided (・.

j 2\lJt'3 11° As shown in FIG. 54, the slope block 26 can also extend beyond the front wall 5. It may be an independent precast as described above, or it may be integrated with the front wall. Its direction and position may be arbitrary as long as it can be joined to adjacent blocks. FIG. 54 shows a cross-sectional view of the installation of the slope block.

As described in 1ifJ, if the rear space chamber (Fig. 41) K is filled with chestnut stone 17 for drainage, if there is a lot of spring water in the ground, the chestnut stone 1
If the water permeates through the chestnut stone at a high speed by draining water from the block 7, the water inside the block may flow out, so it is necessary to prevent this. As shown in FIG.
Attach the plate to 0 with an inclination of 1χ) 1v (louvered).

The water in Kuriishi 17 flows into the block under pressure, or the soil inside the block is drained by a plate, so the outside is covered with a leak prevention material that is attached to the block. 59-gJ", 6112:J-"-51 The use of spill prevention material has this effect.

The spill prevention rack shown in Figure 59 is a box 30K made of plastic or other mulch material, and a chestnut stone 17 is placed on the spring water fl'll or flowing water side. The box has a partition wall 6 with -C, and the box and partition wall are provided with openings through which gravel, 11'X gravel, or bags do not flow out. Each opening 9. io, 11, slope again [J Tsuku 2
The soil 18 in the block will not flow out even if there is water or running water. Depending on the river conditions, if you put a float made of plastic or other building material in the sand, the float will rise in the event of a flood and there will be no gaps between the gravel and the soil will flow out. prevent.

Furthermore, if a lip 62 is provided on the box 30 if necessary, it will be fixed to the concrete and will not peel off or fall off. Instead of a box, gravel or the like may be placed in a box or bag made of building materials such as iron rope, cotton, or chemical fiber (or may be combined with the box described above).

FIG. 60 shows a box 30 filled with rod-shaped fibers.

In addition, mortar and concrete IJ-t with sudden air contamination (
When the mixed material 34 (with air in it) is added to the fibers 65, fibrous foam concrete is obtained. The presence of fibers gives the aerated concrete strength, and the numerous pores are connected, allowing for better water and air circulation and helping to prevent soil from flowing out. The material of the box and fibers may be construction materials such as plastic, steel, fiberglass, etc.

FIG. 61 shows a cross section of an outflow prevention material 19 containing net-like or coiled fibers instead of rod-like fibers.

Depending on ±18 within the block, the box, wire mesh, etc. described above may contain only gravel, or may contain crushed gravel, sand, etc., or may be recombined with a mixed material. Also, depending on the river conditions, the soil 18 in the block may be installed simply by placing it in a bag, or it may be combined with the above-mentioned gravel and other mixed materials.

Depending on the soil quality of the soil 18 in the block, the mixed material 64 may be omitted and only the fibers 35 may be used. The present prevention moon 19 is not limited to those shown in FIGS. 55 and 59 to 61 described above, and such materials may be used in combination as appropriate.

In addition, the mixed material 34 is applied to the soil layer 24 of the front wall, each opening 9,
10゜11 and 2.5K You can also place the mixture directly (゛. When pouring the mixed material directly on the surface 24 of the special pressure soil, place paper, paper, etc. under it.
It is also possible to spread cloth, etc. depending on the soil 18 as it is difficult for the soil to change chemically.Also, only the fibers 35 are placed in each opening 9.10.

You can also fill it with sandbags 66. (Figure 49) It is convenient to apply the leakage prevention material directly to the front wall and opening.

Build A: If the composite phase 67 can be taken into the block at the time of i, i stacking, several stages of blocks are laid, and Kuriteki 17 and i
It is easy to install because it can be installed in 1-2 days. In this case, the composite phase 37 is buried. If you want to put a wire number on the bent part or middle part of the lumber or the middle part of the lumber, you can bend it freely. At the time of construction, it is a great time.

The advantage of Harai ( ) is that the plastic blue construction material Ikoto Nari may almost fall backwards, so Figure 57, 5
As shown in Fig. 8, when the support plate 38 is completed, the groundflies block follows the support plate 1. I will support you. When filling the back of the back wall 1 with soil, it will serve as a partition plate from the Kuriishi moromi soil. 57 and 58 as necessary. A 6-piece board can also be used as a box dog. In this case, the position is L-1q. When the main blocks are laid in the same manner, the line of the front wall 5 may be monotonous. In this case, it is aesthetically pleasing to provide unevenness on the front wall. It has an excellent structure.The plan view is shown in Part 6.
