The first embodiment will be explained.
An anti-slip pin 2 is provided on the upper side, and a bottom plate 4 of the large-sized concrete block product A is mounted on the foundation surface 1 through a supporting means 3.
And the bottom plate 4 of the large-sized concrete block product A is held in a predetermined horizontal state or an inclined state by the supporting means 3, and the base surface 1 and the bottom plate 4 of the large-sized concrete block product A are supported. Hardener 6 such as cement milk or mortar milk in the gap 5
Is filled with the anti-slip pins 2 in the hardening agent 6 to install the large concrete block product A on the foundation surface 1.

The large-sized concrete block product A of this embodiment shows a case where a retaining wall concrete block for retaining soil is adopted (the same applies to the second and third embodiments described later).
For example, a drainage block or the like may be used.

The slip prevention pin 2 employs a metal rod-shaped body having a predetermined length. Further, the anti-slip pins 2 are formed so as to be integrally embedded at appropriate places on the base surface 1 when the base surface 1 is formed. Since the base surface 1 with the anti-slip pins 2 is formed in this manner, it can be easily formed. Further, the layout structure of the slip prevention pin 2 can be appropriately changed in design.

Next, a specific installation method will be described.

First, the large-sized concrete block product A is installed and adjusted in a correct state on the foundation surface 1 by an appropriate method, and the bottom surface four corners of the bottom plate 4 of the large-sized concrete block product A in this correct state and the foundation surface 1 are adjusted. The liner plate 3 as an example of the support means 3 in the gap 5 between
Arrange A to maintain the correct posture.

Next, the gap 5 between the bottom plate 4 and the foundation surface 1 of the large-sized concrete block product A is filled with the hardening agent 6 through the filling port 12 provided in the bottom plate 4 to fill the slip prevention pin 2 Place the large concrete block product A on the foundation surface 1 with the curing agent 6 buried in the
The construction is completed after waiting for the curing agent 6 to cure.

At this time, in this embodiment, a seal 13 is provided around the gap 5 between the bottom plate 4 and the foundation surface 1 of the large-sized concrete block product A, and the curing agent 6 flows out from the side by this seal 13. Is being prevented. This point is
The same applies to the second and third embodiments described later.

According to the present embodiment thus installed, the anti-slip pins 2 projecting from the base surface 1 are fixed in a buried state in the hardened curing agent 6, so that the anti-slip pins 2 are so-called. The hardener 6 and the base surface 1 are fixed very firmly by playing a role like a reinforcing bar.
Therefore, compared to the conventional installation method without such a slip prevention pin 2, the large-sized concrete block product A has a curing agent 6
Since it is more firmly fixed to the foundation surface 1 via the, the large concrete block product A exerts an extremely strong resistance against the movement toward the front even if earth pressure is applied from the rear. Therefore, the large-sized concrete block product A (curing agent 6) is firmly fixed so as not to slide forward with respect to the foundation surface 1.

Further, as compared with the conventional installation method, since it is substantially necessary to change the anti-slip pins 2 to project from the base surface 1, it is possible to easily implement the present invention.

Explaining the second embodiment, a support 7 having an anti-slip pin 2 protruding from the top is provided on the foundation surface 1, and a large concrete block product A is provided on the support 7.
The bottom plate 4 of the large concrete block product A is held on the base plate 1 by holding the bottom plate 4 of the large concrete block product A against the support body 7 in a predetermined horizontal state or in an inclined state by gyro-basing operation of the large concrete block product A. By filling the gap 5 with the lower surface of the hardener 6 such as cement milk or mortar milk, the support 7 and the anti-slip pins 2 are embedded in the hardener 6 and the large concrete block product A is attached to the foundation surface 1. It is to be installed.

The support body 7 of this embodiment employs a long supporting bar member 7A having a folded-back cross-section with an anti-slip pin 2 projecting from the upper part, and one supporting bar member 7A is provided on the base surface 1 so as to project. The case is shown.

More specifically, FIGS. 3 and 4 show a case where an angle member having an L-shaped cross section is adopted as an example of the supporting bar 7A, and FIG. 5 shows a channel having an inverted U-shaped cross section. The case where the material is adopted is shown. The supporting bar 7A may have any shape as long as the large concrete block product A can be favorably swung.

The slip prevention pin 2 has the same structure as in the first embodiment.
It uses a metal rod. Further, in the drawings, the length dimension of the anti-slip pin 2 is set so that the top of the support bar 7A and the upper end of the anti-slip pin 2 have substantially the same height.

Although the degree of protrusion of the anti-slip pin 2 with respect to the supporting bar 7A can be changed as appropriate, if the anti-slip pin 2 is projected higher than the apex of the supporting bar 7A, the supporting bar is supported. since 7A Yajirobe operation of a large concrete block products a to fulcrum there may not satisfactorily performed, the length of the sliding prevention pin 2 so that the protruding top portion by remote low height of the bearing crosspieces 7A It is preferable to set.

Further, the supporting bar member 7A for the anti-slip pin 2
The design of the layout structure can be changed appropriately.

The supporting bar 7A is integrally formed in the base surface 1 when the base surface 1 is formed. In this way, the base surface 1 with the supporting crosspieces 7A is configured, so that it can be easily configured.

Next, a specific installation method will be described.

First, the supporting bar 7A is placed at a position where the center of gravity of the lower surface of the large-sized concrete block product A or its vicinity contacts the foundation surface 1, and the supporting bar 7A is placed.
The large-sized concrete block product A is placed so that the center of gravity of the large-sized concrete block product A or its vicinity is aligned.

At this time, the position of the large-sized concrete block product A can be easily corrected by swaying or sliding in a predetermined direction by the gyro-bas operation using the supporting bar 7A as a fulcrum.

Therefore, with this support bar 7A, for example,
It is easy to match the retaining wall plate 11 of the adjacent large-sized concrete block product A with the correct inclination state and to match the adjacent large-sized concrete block product A exactly. It will be easy to always correct the correct position and state.

In addition, for example, for the convenience of installation work, there is a case where it is desired to swing or slide the large-sized concrete block product A in only one of the front-rear direction and the left-right direction. The installation method of this embodiment using 7A becomes extremely useful. Also,
It is advisable to change the installation direction of the support bar 7A depending on the direction in which it is desired to rock.

Subsequently, when the large-sized concrete block product A is corrected to the correct state, the liner plate 3A as the support means 3 is arranged in the gaps 5 between the four corners of the bottom plate 4 of the large-sized concrete block product A and the foundation surface 1. And maintain the correct posture.

Next, the gap 5 between the bottom plate 4 and the foundation surface 1 of the large-sized concrete block product A is filled with the hardening agent 6 from the filling port 12 provided in the bottom plate 4 to fill the slip prevention pin 2 Place the large concrete block product A on the foundation surface 1 with the curing agent 6 buried in the
The construction is completed after waiting for the curing agent 6 to cure.

According to the present embodiment thus installed, the supporting bar 7A with the anti-slip pins 2 projecting from the base surface 1 is fixed in the hardened hardener 6 in a buried state. The anti-slip pin 2 plays the role of a so-called rebar, and the hardener 6 and the base surface 1 are fixed extremely firmly. Therefore, compared with the conventional installation method without the anti-slip pin 2 as described above. Since the large concrete block product A is more firmly fixed to the foundation surface 1 through the curing agent 6, the large concrete block product A tends to move forward even if earth pressure is applied from the rear. Thus, the large-sized concrete block product A (curing agent 6) is firmly fixed in a state where it does not slide forward with respect to the foundation surface 1.

Further, as compared with the conventional installation method, since it is only necessary to change the support bar 7A having the anti-slip pin 2 projecting from the foundation surface 1 to the projecting state, it is possible to easily implement the invention. Becomes

In this embodiment, the case where the long support bar 7A is adopted as the support 7 is shown, but a quadrangular plate or a lump such as a stone roller may be used as the support 7.
In this case, not only one direction such as the front-rear direction and the left-right direction but also the swaying motion or the sliding motion can be performed in almost all directions, so that the degree of freedom of position correction is further improved.

Explaining the third embodiment, this embodiment is the same as the second embodiment except that before filling the gap 5 between the foundation surface 1 and the bottom surface of the bottom plate 4 of the large concrete block product A with the hardening agent 6, or Before the hardening agent 6 hardens, the nail 9 which penetrates at least the bottom plate 4 of the large-sized concrete block product A from above the bottom plate 4 of the large-sized concrete block product A and penetrates at least the bottom plate 4 of the large-sized concrete block product A to be hardened. It is something to drive in.

Further, in this embodiment, a large concrete block product A in which a nail driving hole 10 for driving the nail 9 into the bottom plate 4 is formed and a slide preventing projection 8 is provided on the bottom plate 4 is provided. I'm using it.

The sliding prevention projections 8 hung on the bottom plate 4 of the large-sized concrete block product A are simple metal rods. In addition, the anti-slip protrusion 8 is
When the large-sized concrete block product A is concrete-molded, the bottom plate 4 is insert-molded.
In this way, the large-sized concrete block product A with the sliding prevention projection 8 has excellent mass productivity and can be constructed at low cost. Further, the designing position and the number of the sliding prevention projections 8 vertically extending from the bottom plate 4 can be changed appropriately.

The nail 9 is a large concrete block product A.
The length of the bottom plate 4 is such that the bottom plate 4 and the curing agent 6 are penetrated into the base surface 1 by driving from the upper surface of the bottom plate 4.

The outer diameter of the nail 9 is set so as not to create a large gap with the inner surface of the nailing hole 10.
Thereby, the large-sized concrete block product A is hardly moved with respect to the nail 9, and the effect of preventing the large-sized concrete block product A from sliding on the foundation surface 1 after the installation is improved. In addition, the driving position of the nail 9, that is, the position and the number of the nail holes 10 formed on the bottom plate 4 in the present embodiment can be appropriately changed in design.

Explaining a concrete installation method, in the second embodiment, the large-sized concrete block product A is corrected to a correct state, and the gaps between the lower four corners of the bottom plate 4 of the large-sized concrete block product A and the foundation surface 1 are corrected. 5 is provided with a liner plate 3A as a support means 3 to maintain the correct posture, and then the large concrete block product A
By injecting and filling the gap 5 between the bottom plate 4 and the base surface 1 of the hardener 6 from the injection port 12 provided in the bottom plate 4,
The large-sized concrete block product A is installed on the foundation surface 1 with the anti-slip pins 2 and the anti-slip protrusions 8 embedded in the curing agent 6.

Then, a large-sized concrete block product A
A nail 9 is driven from above the bottom plate 4 toward the base surface 1 so as to penetrate the bottom plate 4 of the large-sized concrete block product A and the curing agent 6 and be driven to the base surface 1. The nail 9 is driven in before the hardening agent 6 is hardened so as not to impair the workability.

According to the present embodiment thus installed, the anti-slipping projections are provided from the base plate 1 of the large concrete block product A and the supporting crosspiece 7A with the antiskid pins 2 projecting from the foundation surface 1. Since 8 and 8 are fixed to the hardened curing agent 6 in a buried state, the anti-slip pins 2 and the anti-slip projections 8 play a role of so-called reinforcing bars. That is, the hardener 6 and the base surface 1 are extremely firmly fixed to each other by the anti-slip pins 2, and the anti-slip protrusions 8 are provided.
As a result, the hardener 6 and the large-sized concrete block product A are extremely firmly fixed to each other. Therefore, compared with the conventional installation method in which the anti-slip pins 2 and the anti-slip protrusions 8 are not provided, the large-sized concrete block is installed. The product A is more firmly fixed to the base surface 1 via the curing agent 6.

Further, in this embodiment, since the nail 9 is driven in to reinforce the fixed state, the large concrete block product A tends to move forward even if earth pressure is applied from the rear. Since it exhibits extremely strong resistance against it, the large-sized concrete block product A (hardening agent 6) is firmly fixed in a state where it does not slide forward with respect to the foundation surface 1.

Therefore, in this embodiment, the first,
As compared with the second embodiment, a stronger effect of preventing the shear movement can be obtained.

In this embodiment, the case where the large concrete block product A in which the bottom plate 4 is provided with the nail driving holes 10 for driving the nails 9 is used, but the large concrete block product without the nail driving holes 10 is shown. The nail 9 may be directly driven into the bottom plate 4 of A.

Further, the nail 9 may be driven in from the injection port 12, and by doing so, the installation method of this embodiment using the large-sized concrete block product A with the injection port 12 can be realized at a lower cost. In addition, the nail 9 can be easily driven through the injection port 12.

In the present embodiment, the bottom plate 4 to the base surface 1
Although the nail 9 having a length dimension that can be driven up to is adopted, the nail 7 may have a length that penetrates the bottom plate 4 of the large-sized concrete block product A and is driven into the curing agent 6.

In this embodiment, the rod-shaped anti-slip projection 8 is shown, but the lower end of the anti-slip projection 8 may be bent at a substantially right angle to form an L-shape. Then, after the installation, the anti-slip projection 8 also exerts an anti-slip effect in the vertical direction, so that the anti-slip projection 8 is more resistant to the hardener 6 in the retaining resistance. Therefore, large concrete block product A
The resistance force to prevent falling is further improved, and a stronger resistance force to prevent forward sliding movement is exhibited as compared with the case where the rod-shaped anti-slip projection 8 is used.

In the third embodiment, the installation method may be such that the nail 9 is driven by using the large-sized concrete block product A which does not have the anti-slip projection 8 or the large anti-slip projection 8 is installed. The concrete block product A may be used without installing the nail 9.

In the figure, reference numeral 14 is gravel which constitutes the foundation surface 1, and 15 is a cobblestone.
