Abstract

PROBLEM TO BE SOLVED: To improve workability by disposing a projecting section in upright to a bearing plate placed on a foundation surface, bearing the center section of gravity of a concrete block and adding balancing toy action. SOLUTION: A bearing plate (b), to which a projecting section 3A is projected, is placed on a foundation surface 1, and the place 2 of the center of gravity of the large-sized concrete block (a) or a section in the vicinity of the place 2 is borne by the projecting section 3A. The bottom plate 4 of the block (a) is borne under a specified horizontal state or inclined state as using the projecting section 3a as a supporting point while vertical adjusting devices (d) are arranged on lower sides at several places of the periphery of the bottom plate 4 and the block (a) is adjusted at a correct place and in a correct posture. Spaces 9 are disposed into an opening 5 between the foundation surface 1 and the underside of the bottom plate 4 of the block (a) and the posture is held, and the opening 5 is filled with a curing agent 7 and the block 1a is fixed onto the foundation surface 1. Accordingly, the adjacent concrete blocks can be joined accurately, and the adjacent retaining-wall surfaces can be executed simply in the same surface shape, and the efficiency of the execution of works can be improved largely.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jiberobe for installing large concrete blocks such as retaining wall blocks, drainage gutter blocks, fence ditch blocks, and box culverts used for forming retaining walls, drains, drainage tunnels and the like. It is about the bearing.

[0002]

2. Description of the Related Art
For example, when constructing a retaining wall block, lower this retaining wall block on a foundation surface with a track lane, etc., align it with the next concrete block in front and rear at a predetermined position, and Although the comrades were correctly butted, it was extremely difficult to line up the front faces of the upper retaining wall boards where the right and left side edges of each retaining wall board were correctly abutted because the base surface was not always flat.

For this reason, each time the construction is carried out, the retaining wall block is lifted by a truck crane or the like, an intervening object is interposed between the foundation surface and the bottom plate, and is pushed to make the side edges correctly abut and the front surface of the retaining wall plate is flush. However, since this retaining wall block is large, it is very troublesome work and there is a drawback that the work efficiency is reduced accordingly.

Accordingly, the present inventor has proposed a technique disclosed in Japanese Patent Publication No. 7-7242.
As in No. 0, a projection is provided at the center of gravity of the lower surface of the bottom plate of the concrete block, and the concrete block can be rocked or moved on the foundation surface using this projection as a fulcrum without using a crane. Concrete blocks that can be easily and correctly installed in a predetermined position have been proposed, and have been very well received.

According to the present invention, concrete blocks are constructed based on the idea of providing protrusions on the foundation surface, instead of providing protrusions on the lower surface of the bottom plate of the concrete block. The present inventors have found that very excellent results can be obtained from the standpoint of the present invention, and propose a Yazirobe support for the installation of this large concrete block.

[0006]

The gist of the present invention will be described with reference to the accompanying drawings.

A protrusion 3A is provided substantially at the center of the support plate b placed on the base surface 1 to support the center of gravity of the concrete block a or in the vicinity thereof and to add a jibby effect to the concrete block a. The present invention relates to a jijirobei bearing body for installing a large concrete block.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to implement the invention), which is considered to be the best, will be briefly described with reference to the drawings, showing the operational effects thereof.

A bearing plate b is placed on the base surface 1, and a concrete block a is placed on the projection 3A standing on the bearing plate b so that the center of gravity or the vicinity of the lower surface of the concrete block a is aligned. Then, the concrete block a can be rocked or sheared by the jirobe action using the projection 3A as a fulcrum, and the concrete block a can always be easily corrected to the correct position and correct state.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a preferred embodiment of the present invention, in which a projection is provided at a position where the lower surface center of gravity position 2 of the concrete block a of the base surface 1 on which the large concrete block a is installed or the vicinity thereof abuts. A support plate b on which the protrusion 3A is protruded is placed, and the concrete block a is placed on the protrusion 3A of the support plate b so that the center of gravity 2 of the concrete block a or the vicinity thereof is aligned with the bottom plate of the concrete block a. 4 is held in a predetermined horizontal or inclined state, and a gap 5 between the base surface 1 and the lower surface of the bottom plate 4 of the concrete block a is filled with a hardening agent 7 such as concrete mortar, cement mortar, resin mortar, and the like.
The concrete block a is installed on the top.

FIG. 2 shows an example of a support plate b having a protrusion 3A protruding therefrom. The protrusion 3A having a curved top is formed substantially at the center of the rectangular support plate b. It is set up and configured.

The projecting height of the projection 3A needs to be high enough to swing the supported concrete block a satisfactorily, but can be appropriately designed according to the size of the concrete block a.

In the present embodiment, as shown in FIG. 3, black ink 18 is provided on the foundation surface 1 for placing the concrete block a, and the vicinity of the center of gravity 2 of the concrete block a is installed on the foundation surface 1 in advance. If the mark 6 is attached as a guide for installing the support plate b, the work can be performed smoothly.

The concrete block a is corrected to a correct position and a correct posture with the protrusion 3A as a fulcrum. At this time, an up-down adjusting device d is arranged at several places below the peripheral edge of the bottom plate 4 of the concrete block a.

Subsequently, in order to maintain this correct state, the bottom plate 4
The gap 5 between the base and the base surface 1 is held in a posture through a suitable spacer 9 such as a wedge or the like.
And fix the concrete block a on the base surface 1.

The hardening agent 7 may be injected into the gap 5 from the inlet 8 or from the side of the bottom plate 4 of the concrete block a.

When the hardening agent 7 is injected, it is preferable to arrange a leakage preventing plate around the gap 5 so that the hardening agent 7 does not flow out from the side, or to fill the gap 5 with soil or the like.

In order to install the concrete block a in a correct state, it is desirable to use a level together.

In the figure, reference numeral 16 denotes gravel, and reference numeral 17 denotes rubble stone.

[0020]

Since the present invention is constructed as described above, the bearing plate of the present invention is mounted on a base surface, and the center of gravity or the vicinity of the lower surface of the concrete block is placed on the projection standing on the supporting plate. By just placing the concrete block so that it matches, the concrete block can be rocked with a slight force by the jijirobe action with this projection as a fulcrum, and it can also be moved with a slight force by this Become.

Therefore, it is possible to easily join the concrete blocks of the neighbors together and to make the retaining walls of the neighbors flush with each other, and to install a concrete block which greatly improves the construction efficiency. It becomes a jirobei bearing for the installation of an excellent large concrete block that can be implemented.
