Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a block insertion material,
In particular, the present invention relates to a block interposing material that is suitable for use in constructing a fence or a wall formed using a concrete block.

[0002]

It has been a long time since concrete blocks have been used. These are used for various purposes such as walls, walls of buildings, partitions in buildings, partitions for depositing ore, gravel, sand, etc., earth retaining for flower beds and earth fills, and various other purposes. Conventionally, these structures have been constructed by a method in which mortar is sandwiched between each of them and they are stacked one by one.

[0003]

Concrete blocks must be accurately stacked in the same space in both the vertical and horizontal directions (regulation is 1 cm). This is because if the gaps are not uniform, it looks bad, but if the weight is not uniform, the load resistance and seismic resistance are reduced, which is dangerous. Therefore, it takes a lot of time to stack concrete blocks. Generally, it is said that three people take three days per 100 pieces. The purpose of the present invention is to reduce such man-hours,
At the same time, it is to reduce the required materials such as cement and sand for that purpose.

[0004]

In order to achieve the above object, the invention of claim 1 is provided with a plate-shaped portion and four columnar portions projectingly provided on the plate-shaped portion, and the plate-shaped portion has vertical and horizontal directions. The columnar portions are arranged between four blocks that are adjacent to each other in the direction, and the columnar portions are inserted into the respective cavities of the four blocks. In the invention of claim 2, a peninsula-shaped portion and a cove-shaped portion are formed at both ends of the plate-shaped portion. In the invention of claim 3, a constricted portion is formed at the root of the peninsular portion, and a narrow portion corresponding to the constricted portion is formed at the opening of the cove-shaped portion. In the invention according to claim 4, the columnar portion is hollow. The block to which the present invention is applied is not limited to the concrete block. In the "block" referred to in each claim,
Includes various blocks other than concrete. But common is concrete blocks. Therefore, hereinafter, only the case where the concrete block is applied will be described. Since the "concrete block" seems to have been long, we will simply call it "block".

[0005]

The size of the block is usually 39 cm wide, 19 cm high and 12 cm deep. When the block insertion material of the present invention is applied to this, the plate-shaped portion has, for example, a width of 39 cm,
The depth is 10 cm and the thickness is 1 cm. The plate-shaped portion is arranged between four blocks vertically and horizontally stacked. Specifically, the half is arranged between two blocks vertically stacked, and the other half is arranged between the two blocks vertically stacked next to each other. At least four columnar portions project from the plate-shaped portion. Although the blocks have cavities formed therein, the pillars are inserted into the cavities of the four blocks stacked vertically and horizontally. In the invention of claim 2, a peninsula-shaped portion and a cove-shaped portion are formed at both ends of the plate-shaped portion. By interlocking these peninsula-shaped portions and the cove-shaped portions of the adjacent interposing materials, the displacement of the interposing materials in the depth direction is prevented. In the invention of claim 3, a constricted portion is formed at the root of the peninsular portion, and a narrow portion corresponding to the constricted portion is formed at the opening of the cove-shaped portion. These are engaged in such a manner that the narrow portion enters into the constricted portion like the combined portion of the jigsaw puzzle. In this way, in addition to the depth direction,
A shift in the width direction is also prevented. In the invention of claim 4, the columnar portion is hollow. If necessary, a reinforcing bar or the like is inserted here.

The first embodiment (reference numeral 10) is shown in FIGS. This is an example of the block insertion material of claim 4 which cites claim 1. 3A is a front surface, FIG. 3B is a plane surface, FIG. 3C is a bottom surface, and FIG. The back surface is the same as the front surface (A), and the right side surface is the same as the left side surface (D). FIG. 4 (A) shows FIG.
FIG. 4B shows a cross section taken along the line C2-C2 of FIG.
3 shows a cross section taken along the line C1-C1 of FIG.

The block insertion member 10 is manufactured by, for example, integral molding using a mold. It can also be recycled by crushing plastics and other waste materials and mixing these with synthetic resins. The block insertion material 10 has a plate-shaped portion 11
An upper columnar section 12, a lower columnar section 13, and a bonding buried line 14. The plate-like portion 11 has a width of 39
cm, thickness 1 cm, depth 10 cm, and an octagonal hollow upper column 12 and lower column 13 are vertically provided. The shape of the horizontal cross section of the upper columnar part 12 is the same as the shape of the horizontal cross section of the hollow part 15 of the lower columnar part 13, and the tip 16 of the upper columnar part 12 has a block insertion member 10 arranged on it. And the like, the opening 1 of the hollow portion 15 of the lower columnar portion 13 of the upper block interposer 10 is hit.

0s are combined. Reference numeral 18 is a hollow portion of the upper columnar portion 12. Further, the connecting buried wires 14 are provided upright on both ends of the plate-like portion 11.

FIG. 1 shows an example in which nine blocks 1-1 to 1-9 are stacked by using the block insertion members 10-1 to 10-4. The figure (A) shows the front, and the figure (B) shows the left side. However, the top block 1-1 ~
1 to 3 are shown in a state in which they are positioned above before being stacked. Similarly, three blocks 1-4 to 1-6 arranged in the horizontal direction in the center
Shows the one broken along the line A2-A2 in the same figure (B) (the block insertion members 10-3 and 10-4 are not broken). Further, the left and right sides of each block 1 on both sides are omitted so that details can be expressed as large as possible. Further, since the figure becomes difficult to see, the reference numerals of the details of the block 1 and the block insertion member 10 are not added in FIG. 1 (see FIG. 2, FIG. 3 or FIG. 4).

Stacking is performed as follows. First, place the first block on the foundation with a gap of 1 cm (1-7 ~
1-9). At this time, the vertical cavities 3 of the adjacent blocks 1 form the synthetic cavities 21-5 and 21-6. Each cavity 2 and composite cavity 21 of these blocks 1-7 to 1-9
The lower columnar portion 13 of the block interposer 10 is inserted into. In this case, the lower columnar portion 13 is placed so as to straddle each of the blocks 1-7 to 1-9. Specifically, the block insertion material 1
The lower columnar section 13-1 of 0-3 is in the cavity 2-3 of the block 1-7, the lower columnar section 13-3 is in the cavity 2-1 of the block 1-8, and the lower columnar section 13-2 is between them. 21 into the synthetic cavity 21-5. Similarly, the block interposer 10-4 is placed so as to straddle the blocks 1-8 and 1-9. Embedding line 14 for connecting adjacent block insertion members 10-3 and embedding line 14 for connecting adjacent block insertion members 10-4.
Twist together and connect them.

The blocks of the second stage are arranged on this (1-
4-1-6). Of course, the bottom blocks 1-7 to 1-9 are aligned and stacked. Upper columnar portion 12 of the block insertion material 10-3
-1 is the cavity 2-3 of the block 1-4 stacked on it
Further, the upper columnar portion 12-2 engages with the composite cavity 21-3, and the upper columnar portion 12-3 engages with the cavity portion 2-1 of the block 1-5. Upper columnar portion 12-1 of the block insertion material 10-4
12-3 are engaged with the respective cavity portions 2-3, 2-1 of the blocks 1-5, 1-6 and the composite cavity 21-4, respectively. The block insertion material 10-1 and the block insertion material 1 are provided on the blocks 2-4 to 2-6 in the second step in the same manner as in the first step.
Put 0-2. After placing, the tips 16 of the upper columnar portions 12 are hit with a rubber hammer or the like. With this, the tips 16 of the upper columnar portions 12 of the block insertion members 10-3 to 10-4 are
The block interposing members 10-1 to 10-2 are tightly fitted into the openings 17 of the hollow portions 15 of the lower columnar portions 13.

When this operation is repeated, the upper columnar portion 12 and the lower columnar portion 13 of each block interposing member 10 arranged between the blocks 1 are fitted in order, and both are connected. Therefore, the blocks 1 of each stage are tightened from above and below, and the longitudinal direction of the block wall or the like is firmly fixed. In addition, each upper columnar portion 12 and lower columnar portion 13 formed in one block interposer 10 are adjacent to each other in the block 1.
Engaged in the cavity 2. Therefore, each block 1 is firmly fixed in the lateral direction. After stacking the required number of blocks 1, mortar can be applied to the gaps (joints) of each block 1. This is the end of work. The depth of the block 1 is 12 cm, while the depth of the plate-like portion 11 is 10 c.
Since it is m, the joint depth is 1 cm.

A second embodiment is shown in FIG. 5 (A). However, in this figure, the blocks 1 and the like are not shown, and only the plan view of a state in which three block insertion members 30 of the second embodiment are laterally connected is shown. This embodiment is different from the first embodiment in that a cove-shaped portion 32 and a peninsular portion 33 are provided at both ends of the plate-shaped portion 31. Others are the same as those in the first embodiment (the reference numeral of the columnar portion 12 is omitted because the drawing becomes difficult to see). This block insertion material 30 is, for example, a block insertion material 3 on a certain block 1.
After 0-1 is placed, the peninsular portion 33-1 is fitted over the cove-shaped portion 32-2 of the next block interposer 30-2 from above, thereby repeating each peninsular shape. The part 33 and the next cove-shaped part 32 are sequentially engaged with each other. Then, in order or at the end, the bonding embedded wires 14 are twisted together and fixed to each other (reference numeral 34). By making the shapes of both ends of the plate-like portion 31 into such a shape, it is possible to reliably prevent the positional displacement of each block interposing member 30, and by extension, each block 1 in the depth direction (arrow Y direction).

A third embodiment is shown in FIG. 5 (B). The display method in this figure is the same as that in the second embodiment. The block insertion member 40 of this embodiment is a modification of that of the second embodiment. The narrow portion 46 is provided at the opening of the cove-shaped portion 42, and the constricted portion 4 is provided at the base of the peninsula-shaped portion 43.
5 is different from that of the second embodiment in that the connection line 5 and the connection embedding line 14 are deleted. Others are the same as the second embodiment. This block interposer 40 also combines adjacent peninsula-shaped portions 43 and cove-shaped portions 42 in the same shape as in the second embodiment. Since the narrow portion 46 engages with the constricted portion 45 in such a manner as to enter the constricted portion 45, each block interposing member 30 and thus each block 1 is not only displaced in the Y direction but also displaced in the width direction (arrow X direction). Will also be prevented.
The connecting buried line 14 is also unnecessary (maybe, in the first and second embodiments, the connecting buried line 14 may be omitted).

A modification of the first embodiment will be described. In the middle of the upper column and the lower column (12-2, 13
-2) is a connecting portion (composite cavity portion 2) of the two blocks 1.
It is located in 1), and prevents the displacement of both at this part. That is, these have a function of controlling the displacement of the blocks 1 in the horizontal direction, but if one wants to simplify the structure, one of them may be omitted, or it may not be provided. Although the upper column 12 and the lower column 13 are octagonal, they may have any shape as long as they can be inserted into the cavity 2 of the block 1. The upper columnar portion 12 and the lower columnar portion 13 may be formed of a slightly elastic material, and may be hit with a hammer or the like to be fitted into each cavity 2. By doing so, the blocks are fixed more securely in both the vertical and horizontal directions. The upper column 12 and the lower column 13 are arranged so that the upper and lower columns are tightly connected to each other. However, for a structure in which it is not necessary to use much nerve for fixing in the vertical direction, the tip 16 of the upper columnar portion 12 may simply be located in the hollow portion 15 of the lower columnar portion 13. Further, the tip 16 of the upper column 12 may simply face the lower end of the lower column 13. Upper column 12
The lower columnar portion 13 was hollow (15, 18). This is convenient for passing the reinforcing bars. Block insert 1
You can also save the materials that make up 0. However, it need not be hollow. In such a case, the embodiment of the invention of claim 1 is provided.

[0015]

As described above, according to the first aspect of the present invention, the four columnar portions are provided on the plate-shaped portion so as to project, and the plate-shaped portion is arranged between the four blocks adjacent to each other in the vertical and horizontal directions. A column was inserted into each of the cavities of these four blocks.
As a result, blocks, particularly concrete blocks, can be stacked accurately with the same gap in the vertical and horizontal directions. Therefore, not only craftsmen but also amateurs look great,
It will be possible to easily and quickly construct a block fence with sufficient load resistance and earthquake resistance. Further, since the gap and the hollow portion of the block are closed by the plate-like portion, the amount of mortar to be sandwiched in the gap or the amount of mortar to fall into the hollow portion is significantly reduced. Therefore, the required amount of sand and cement is greatly reduced. In the applicant's test, the conventional method 1
The amount of cement, which was 0 bags / 100 blocks, is 1 bag /
Reduced to 100. In the invention of claim 2, a peninsula-shaped portion and a cove-shaped portion are formed at both ends of the plate-shaped portion. Therefore, the positional displacement of each block interposing material, and thus each block, in the depth direction is reliably prevented. In the invention of claim 3, a constricted portion is formed at the root of the peninsular portion, and a narrow portion corresponding to this is formed at the opening of the cove-shaped portion. Therefore, not only the positional displacement of each block interposing material and thus of each block in the depth direction is prevented, but also the positional displacement in the width direction is surely prevented. In the invention of claim 4, the columnar portion is hollow. Therefore, if necessary, a reinforcing bar can be inserted into this hollow portion.
