【Example】
A specific embodiment of the present invention will be described with reference to the drawings.
[0017]
The drawings show eight preferred embodiments of the present invention. FIG. 1 is a first embodiment, FIG. 2 is a second embodiment, FIG. 3 is a third embodiment, FIG. 4 is a fourth embodiment, 5 shows a fifth embodiment, FIG. 6 shows a sixth embodiment, FIG. 7 shows a seventh embodiment, and FIG. 8 shows an eighth embodiment. Each drawing is a cross-sectional view in which only a portion necessary for explanation is cut out.
[0018]
To explain the first embodiment, a large-sized concrete block product A having a through hole 2 formed in a bottom plate 1 is supported on a foundation surface 3 in a state where the bottom plate 1 of the large-sized concrete block product A is lifted via a bearing means 4. At the same time, the bottom plate 1 of the large concrete block product A is held in a predetermined horizontal or inclined state by the bearing means 4, and cement milk or the like is filled in the gap 5 between the base surface 3 and the bottom plate 1 of the large concrete block product A. A hardening agent 6 such as mortar milk is filled and a large concrete block product A is installed on the base surface 3, and before or after filling the hardening agent 6, a slip prevention pin 7 is put into the through hole 2. A large-sized concrete block characterized in that at least the leading end side of the slip prevention pin 7 is buried in the hardener 6 before hardening. Those relating to the installation method.
[0019]
This embodiment shows a case where the present invention is applied to a retaining wall block for retaining as a large concrete block product A.
[0020]
Further, though not shown in detail, the through holes 2 are formed at a total of three places: a front left and right position of the bottom plate 1 and a rear center position.
[0021]
The slide prevention pin 7 of the present embodiment employs a simple metal bar. When the anti-slip pin 7 is inserted into the through hole 2 of the large concrete block product A which is supported in a state of being floated by the support means 4, the leading end of the anti-slip pin 7 The length of the slide prevention pin 7 is set such that the insertion base end side of the slide prevention pin 7 does not come off from the through hole 2 when it comes into contact with the through hole 5. That is, when the slip prevention pin 7 is inserted into the through hole 2, the leading end side of the slide prevention pin 7 projects into the gap 5 before the slip prevention pin 7 comes off.
[0022]
The slip prevention pin 7 and the through hole 2 are such that the slip prevention pin 7 is not difficult to be inserted into the through hole 2, and when inserted, the slip prevention pin 7 and the inner surface of the through hole 2 The outer diameter of the anti-slip pin 7 and the inner diameter of the through-hole 2 are set and configured so that there is not much gap between the large anti-slip pin 7 and the large concrete block product A. Thus, the effect of preventing the large concrete block product A from shearing with respect to the installed base surface 3 is improved.
[0023]
The arrangement structure (formation position) of the through holes 2 can be appropriately changed in design. However, if the arrangement structure of the through holes 2 is at least as in the present embodiment, the anti-slip pins protruding from the three through holes 2 are provided. It has been confirmed by the applicant's trial experiments that the sample No. 7 provides an extremely good shearing prevention effect.
[0024]
Next, a specific installation method will be described.
[0025]
First, a support body 11 for floating the large concrete block product A from the base surface 3 is placed on the base surface 3 at a position where the center of gravity of the lower surface of the large concrete block product A or the vicinity thereof abuts, and is placed on the support body 11. The large concrete block product A is placed so that the position of the center of gravity of the large concrete block product A or its vicinity is adjusted. The support 11 shown in the drawing simply adopts two flat square plates.
[0026]
At this time, the large concrete block product A can be easily rocked or sheared by the operation of the jirobe with the support body 11 as a fulcrum, so that the large concrete block product A is slightly displaced from a predetermined position. The position of the large concrete block product A can be easily corrected by swinging or shearing the large concrete block product A by the jibebey operation using the support body 11 as a fulcrum.
[0027]
Therefore, by using this bearing body 11, for example, the retaining wall plate 12 of the adjacent large concrete block product A can be flush with the right large concrete block product A, and the right and left sides can be perfectly aligned with the adjacent large concrete block product A. The adjustment is also easily performed, and the large concrete block product A can be easily corrected to the correct position and correct state at all times.
[0028]
Subsequently, when the large-sized concrete block product A is corrected to a correct state, a liner plate 4A as a bearing means 4 is disposed in a gap 5 between four lower corners of the bottom plate 1 of the large-sized concrete block product A and the foundation surface 3. Hold posture.
[0029]
Then, a hardening agent 6 such as cement milk or mortar milk is injected and filled into a gap 5 between the lower surface of the bottom plate 1 and the base surface 3 of the large concrete block product A from an inlet 8 formed in the bottom plate 1. Is hardened and the large concrete block product A is installed and fixed on the base surface 3. Before or after the hardener 6 is filled, the anti-slip pins 7 are put into the through holes 2 provided in the bottom plate 1. Before the leading end side of the slip prevention pin 7 is cured, it is buried in the curing agent 6.
[0030]
Then, the construction is completed after the curing agent 6 is cured.
[0031]
At this time, in this embodiment, a seam 13 is provided around the gap 5 between the bottom plate 1 and the foundation surface 3 of the large concrete block product A, and the seam 13 prevents the hardener 6 from flowing out from the side. ing.
[0032]
According to the present embodiment is installed this way, after installation completion, but the large concrete block product A will undergo soil pressure from the rear, turned the distal end side of the through hole 2 or we put the sliding prevention pin 7 is cured Since the anti-slipping pin 2 functions as a so-called reinforcing bar, the large-sized concrete block product A and the hardener 6 are fixed very firmly because the hardener 6 is fixed in the buried state. The large concrete block product A exerts extremely strong resistance to the forward movement of the large concrete block product A due to the earth pressure, and the large concrete block product A moves forward with respect to the foundation surface 3 (hardening agent 6). It will be firmly fixed in a state where it does not move.
[0033]
Further, since it only adds work just turned conventional installation system and simply through hole 2 or et sliding preventing pin 7 than, be carried out by substantially the same operation as the conventional without work is complicated it can.
[0034]
Describing a second embodiment, the present embodiment is a case where a block with a drain groove 16 is employed as the large concrete block product A in the first embodiment.
[0035]
Although not shown in detail in this embodiment, a case is shown in which the through-hole 2 is formed in the left and right portions of the bottom plate 1 in the middle in the front-rear direction.
[0036]
The third embodiment will be described. This embodiment is different from the installation method of the first embodiment in that before or after the hardening agent 6 is filled into the gap 5 between the base surface 3 and the bottom plate 1 of the large concrete block product A, A nail 9 is driven from above the bottom plate 1 of the concrete block product A toward the foundation surface 3 at least through the bottom plate 1 of the large concrete block product A to reach the hardener 6.
[0037]
The large-sized concrete block product A of the present embodiment uses the large-sized concrete block product A of the first embodiment, in which a nailing hole 10 for driving and inserting a nail 9 into the bottom plate 1 is formed. .
[0038]
Although not shown in detail, the nailing hole 10 is formed in the left and right portions of the bottom plate 1 in the middle in the front-rear direction. Although the design of the arrangement of the nailing holes 10 can be changed as appropriate, it can be seen from the applicant's trial experiments that an extremely good anti-slipping effect can be obtained by using at least the arrangement of this embodiment. Has been confirmed.
[0039]
The nail 9 has a length dimension that is driven from the upper surface of the bottom plate 1 of the large concrete block product A toward the base surface 3 to penetrate the bottom plate 1 and the hardener 6 and reach the base surface 3. ing.
[0040]
When the nail 9 is driven into the nailing hole 10 and inserted, the outer diameter of the nail 9 and the diameter of the nailing hole 10 are so set that almost no gap is formed between the nail 9 and the inner surface of the nailing hole 10. The inner diameter dimension is set and configured so that the large concrete block product A hardly moves with respect to the nail 9, thereby improving the effect of preventing the large concrete block product A from slipping against the foundation surface 3 after installation. .
[0041]
The concrete installation method of the present embodiment will be described. In the installation method of the first embodiment, after the large concrete block product A is installed on the foundation surface 3, the nail is installed from above the bottom plate 1 of the large concrete block product A. When the nail 9 is driven into the base surface 3 through the perforated hole 10, the construction is completed. Alternatively, the nail 9 may be driven before the hardener 6 is filled, and then the hardener 6 may be filled in the gap 5.
[0042]
The nail 9 may be driven before the hardening agent 6 is hardened, or may be driven after the hardening agent 6 is hardened. However, if the nail 9 is driven before the hardening agent 6 is hardened, the driving operation can be performed easily.
[0043]
According to the present embodiment installed in this way, a synergistic anti-shearing effect of the anti-slipping effect of the anti-slip pin 7 and the anti-slipping effect of the nail 9 is obtained. As a result, a more powerful effect of preventing forward shear movement can be obtained.
[0044]
In the present embodiment, a case is shown in which a large concrete block product A having a nailing hole 10 for driving a nail 9 in the bottom plate 1 is used, but the bottom plate of the large concrete block product A without the nailing hole 10 is shown. A configuration in which the nail 9 is directly driven into 1 may be employed. In such a configuration, the nail driving hole 10 does not have to be formed, so that the large-sized concrete block product A can be configured more easily.
[0045]
In this embodiment, a nail 9 having a length extending from the bottom plate 1 to the base surface 3 is employed. The nail 9 extends through the bottom plate 1 of the large concrete block product A to reach the hardener 6. It may be something.
[0046]
Describing a fourth embodiment, this embodiment is a case where a block with a drain groove 16 is adopted as the large-sized concrete block product A in the third embodiment.
[0047]
Further, in the present embodiment, similarly to the second embodiment, a case is shown in which the through holes 2 are formed in the left and right portions of the bottom plate 1 in the middle in the front-rear direction.
[0048]
The fifth embodiment will be described. In this embodiment, a large concrete block product A having an inlet 8 for injecting a hardening agent 6 such as cement milk or mortar milk into a bottom plate 1 is provided on a base surface 3 by a support means. 4, the bottom plate 1 of the large concrete block product A is supported in a floating state, and the bottom plate 1 of the large concrete block product A is held in a predetermined horizontal or inclined state by the support means 4. The hardening agent 6 is filled in the gap 5 between the surface 3 and the bottom plate 1 of the large concrete block product A from the injection port 8, and the large concrete block product A is installed on the foundation surface 3, and the hardening agent 6 is filled. Before or after, an anti-slip pin 7 is inserted into the injection port 8, and the curing agent 6 before hardening at least the input end side of the anti-slip pin 7. Those relating to the installation method of a large concrete block product characterized in that allowed to buried.
[0049]
Specifically, in the first embodiment, the anti-slip pin 7 is inserted into the inlet 8 without providing the through-hole 2 in the bottom plate 1 of the large concrete block product A.
[0050]
Therefore, in this embodiment, in addition to the operation and effect of the first embodiment, the installation method can be performed using the existing large-sized concrete block product A with the inlet 8, so that the installation method with less cost is required. Can be realized.
[0051]
Further, in the case of the present embodiment, as shown in the drawing, a gap is formed between the anti-slip pin 7 and the injection port 8, but the inside of the injection port 8 is also filled with the curing agent 6, and the curing agent 6 in the injection port 8 is filled. Is configured so that the anti-slipping pin 7 and the large-sized concrete block product A are fixed by the hardening of the material, thereby improving the effect of preventing the large-sized concrete block product A from slipping on the foundation surface 3 after installation. It is to be noted that, instead of the configuration of this embodiment, the outer diameter of the anti-slip pin 7 is set to an outer diameter slightly smaller than the inner diameter of the injection port 8 so that the anti-slip pin 7 becomes It is good also as a structure which exerts the same effect as the above by making it hardly move in the inside.
[0052]
Describing the sixth embodiment, the present embodiment is a case where a block with a drain groove 16 is employed as the large concrete block product A in the fifth embodiment.
[0053]
The seventh embodiment will be described. In the present embodiment, in the installation method of the fifth embodiment, before or after filling the hardening agent 6 into the gap 5 between the base surface 3 and the bottom plate 1 of the large concrete block product A, The nail 9 is driven into the hardening agent 6 by penetrating at least the bottom plate 1 of the large concrete block product A from above the bottom plate 1 of the large concrete block product A toward the base surface 3.
[0054]
Specifically, the large-sized concrete block product A of the present embodiment uses nail holes 10 formed at a total of three places, that is, the front left and right positions of the bottom plate 1 and the rear center position. The nail 9 can be driven from the nailing hole 10 toward the base surface 3.
[0055]
The specific installation method of this embodiment is substantially the same as that of the third embodiment, and will not be described.
[0056]
Therefore, in the present embodiment, a synergistic anti-slipping effect of the anti-slipping effect by the anti-slip pin 7 and the anti-slipping effect by the nail 9 is obtained, and therefore, it is even more than in the fifth embodiment. A strong forward shearing action preventing effect can be obtained.
[0057]
Describing an eighth embodiment, the present embodiment is a case where a block with a drain groove 16 is employed as the large concrete block product A in the seventh embodiment.
[0058]
Although not shown in detail, the present embodiment shows a case where the nailing holes 10 are formed in the left and right portions of the bottom plate 1 in the middle in the front-rear direction.

【The invention's effect】
As described above, according to the present invention, a slip prevention pin is inserted from above the bottom plate into the through hole or the injection port provided in the bottom plate, and at least the input end side of the slide prevention pin is provided as a gap between the base surface and the bottom plate. After embedding in the hardening agent before hardening filled in the hardening agent, the hardening agent is hardened and the large concrete block product is installed and fixed on the base surface, so after the installation is completed, the sliding inserted through the through hole or injection port Since the leading end side of the prevention pin is fixed in the hardening agent hardened in the gap in a buried state, the anti-slip pin functions as a so-called reinforcing bar, and the large-sized concrete block product and the hardening agent are extremely firmly fixed. Therefore, compared to the conventional installation method without such anti-slip pins, the large concrete block product is more firmly fixed, so the earth pressure is applied from behind. The large concrete block product exhibits extremely strong resistance to the forward movement of the large concrete block product, and the large concrete block product does not slip forward against the foundation surface (hardening agent). This is an excellent method for installing large-scale concrete blocks to be fixed.
[0061]
Moreover, in the present invention, since it is only necessary to add an operation of merely inserting a slip prevention pin from above the bottom plate into the through hole or the injection port as compared with the conventional installation method, the operation is substantially simplified without complicating the operation. This is an epoch-making large concrete block installation method that can be performed by the same work and is extremely excellent in workability and practicality.
[0062]
In particular, in the invention according to claim 2, since the installation method of the present invention can be carried out using an existing large-sized concrete block product with an injection port, it is possible to realize an installation method with less cost, which is extremely practical. It will be a groundbreaking method for installing large-scale concrete block products with excellent properties.
[0063]
According to the third aspect of the present invention, since the anti-slipping effect of the anti-slip pin and the anti-slipping effect of the nail can be obtained, a stronger anti-slipping force can be obtained by the synergistic anti-slipping effect. This is an extremely practical method of installing large concrete block products that will be demonstrated.
[0064]
Further, the invention according to claim 4 provides a method of installing a large-sized concrete block product having excellent practicality, which exerts a stronger shearing prevention resistance because the nail reaches the base surface. .
[0065]
In the invention according to claim 5, for example, when nails are directly driven into the bottom plate of a large concrete block product, there is a possibility that the bottom plate may be cracked or the strength may be impaired. Such a problem does not occur at all, and the nailing operation can be performed extremely easily with the nailing hole. In addition, since the nailing is performed before the hardening agent hardens, the nailing operation is extremely difficult. It is a practical method of installing large concrete block products that excels in workability, such as easy workability.
