BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block laying support and a concrete block laying structure.

[0002]

2. Description of the Related Art For example, when constructing a flat roof portion of a concrete structure, a slab constructed of cast concrete is generally covered with a heat insulating material layer or a heat insulating material layer. , A waterproof layer made of asphalt felt etc. is provided,
A concrete block is laid on these layers for the purpose of protecting the heat insulating material layer and the waterproof layer.

Here, as a construction means for laying a concrete block, as shown in FIG.
It has been conventionally known that 0 is arranged in a grid point shape and the four corners of the concrete block 8 are supported and fixed to this, but when laying the concrete block by such a construction means, the concrete block is laid. Skilled technology is required to prevent unevenness on the surface and to make the joint width uniform at a predetermined interval so that the finish is good, and it is necessary to secure workers who have mastered such technology. There was a problem.

On the other hand, Japanese Patent Laid-Open No. 59-213803 discloses a support base in which four support base constituent members are joined in a divisible manner and spacer ribs are provided upright between adjacent support base constituent members. The support base is arranged in lattice points, the side surface of the concrete block is brought into contact with the spacer ribs to determine the laying position, and the four corners of the concrete block are supported by the support base constituent members. The use of such a support seems to facilitate the work of laying concrete blocks.

However, in the above-mentioned support base, if the precision of the concrete block is high, the concrete block can be laid without causing any problems, and the spacer ribs sandwiched between the adjacent concrete blocks are used. Although it is possible to form a joint and to lay a concrete block orderly by defining the width of the joint with the thickness of the rib, a commonly used concrete block has low molding accuracy and has a dimensional error. Therefore, in the actual laying work, it is necessary to appropriately change the joint width according to the dimensional error of the concrete block, and in many cases, a gap is created between the spacer rib and the concrete block. Not able to fix concrete blocks horizontally It finishes it is difficult to align the earth also there is a problem that becomes worse.

Further, the support base constituting member of the above-mentioned support base is formed in a box shape, and a drain hole for discharging the invading rainwater is formed at the bottom thereof. When the concrete block is placed on a waterproof layer and the concrete block is supported by the waterproof layer, the supporting base sinks due to its weight and the underlying layer such as the waterproof layer relatively bulges to block the drain hole. There was also a problem that it would not be used as.

The present invention has been made in view of the above problems, and is a concrete block capable of favorably supporting and fixing the concrete block even when the molding accuracy of the concrete block is low and the dimension has an error. Even when a laying support and a drain hole is formed in the support to allow drainage of rainwater and the like, the drain hole can be prevented from being blocked. It is intended to provide a concrete block laying structure.

[0008]

In the concrete block support base of the present invention, each of the four support base constituent members formed in a box shape is separably joined to the other two adjacent support base constituent members, And between the adjacent support base components,
A vertical support piece belonging to one support base constituent member and a vertical support piece belonging to the other support base constituent member are provided so as to be aligned on the same straight line, and a structure for being attached to the vertical support piece It is characterized by comprising a coated member.

On the other hand, in the concrete block laying structure of the present invention, when a concrete block is laid using the above-mentioned concrete block laying support, a plate-like body is interposed between the support and the underlayer. Characterize.

The support base body 2 is composed of four support base constituent members 2a, 2a, 2a, 2a formed in a box shape. The support base 1 of the present invention is a concrete block formed by the support base constituent member 2a. Since it directly supports the ribs 8, ribs 6 are provided inside the ribs 8 to reinforce the vertical load, as in the illustrated example. Further, in the figure, 7 is a drain hole for draining rainwater and the like that have entered the support base constituent member 2a. 2 is a plan view showing an example of the support base body 2, and FIG. 3 is a side view of the same.

Each of the support base constituting members 2a, 2a, 2a, 2a constituting the support base main body 2 has two other support base constituting members 2a adjacent to each other via a joining piece 4 as shown in the drawing.
The support base main body 2 can be divided into two or four by cutting the connecting piece 4 and separating the adjacent support base constituent members 2a.

Further, in the present invention, one support base forming member 2a is provided between the adjacent support base forming members 2a, 2a.
The vertical standing piece 5 belonging to the above and the vertical standing piece 5 belonging to the other supporting base constituting member 2a are provided so as to stand vertically and be aligned on the same straight line.

On the other hand, the covering member 3 is provided with a slit 3a along the longitudinal direction thereof, and the covering member 3 is
As shown in FIG. 1, by inserting the vertical standing piece 5 into the slit 3 a, the vertical standing piece 5 can be attached to the vertical standing piece 5.

The support base 1 of the present invention having such a structure is shown in FIG.
The concrete blocks 8 are laid as shown in FIG. 2, and in the illustrated example, each of the concrete blocks 8 is supported by the support bases 1 arranged at lattice points so that the four corners surround the concrete block 8. Has been done. In addition, the concrete block 8a laid on the peripheral edge is supported on its peripheral side by a support base 1a divided into two parts, and the concrete block 8b laid on the corner portion is divided into four corners by the support base 1b divided into four parts. It is supported. Here, FIG. 6 is a cross-sectional view taken along the line AA of FIG.

In the present invention, it is particularly important that the covering member 3 is attached to the vertical standing piece 5 of the support base body 2, and the concrete block using the support base 1 of the present invention having such a configuration is used. 8 is laid, several kinds of covering members 3 having different thickness t are prepared, and the covering member 3 is appropriately selected according to the joint width T of the concrete block 8 and attached to the vertical standing piece 5. Even if the support base body 2 made with the same size is used, the joint width T when laying the concrete block 8 can be arbitrarily changed, and the concrete block 8 is securely fixed in the horizontal direction and the joint is By laying the concrete blocks 8 in an orderly manner and improving the finish, the laying work of the concrete blocks 8 can be facilitated.

When the peripheral side of the concrete block 8a to be laid around the periphery is supported by the support base 1a which is divided into two, a long covering member 3 as shown in FIG. 6 is used. As shown in FIG. 7, it is preferable that the vertical blocks 5 and 5 belonging to each of the adjacent support base constituent members 2a and 2a are mounted so as to straddle them, so that the appearance of the finish of the peripheral edge of the concrete block 8 can be improved. You can get better.

Here, both ends of the vertical standing piece 5 are bulged in a dumbbell shape to form a bulging portion 5a, and corresponding concave grooves 3b are formed on the inner wall of the slit 3a of the covering member 3. When the covering member 3 is attached to the vertical standing piece 5, lateral deviation of the covering member 3 can be prevented.

It is preferable to use a larger one than the plane size of the base body 2, and by interposing such a plate-shaped body 9 between the support base 1 and the base layer 11, the weight of the concrete block 8 causes the support base 1 to move. Even if it sinks, there is no possibility that the drain hole 7 formed in the support base component 2a will be blocked.

The concrete block laying support and the concrete block laying structure of the present invention are not limited to the case of constructing a flat roof portion of a concrete structure, and for example, a concrete block is laid on a sidewalk or paved. It can also be applied in cases.

[0022]

As described above, the support base for concrete laying according to the present invention uses a support base body having the same size only by appropriately changing the thickness of the covering member according to the joint width of the concrete block. Even if the concrete block is laid, the joint width can be changed arbitrarily, and the concrete block can be fixed securely in the horizontal direction, and the joints can be laid in an orderly manner to achieve a good finish. The concrete block laying work can be facilitated.

Further, according to the concrete block laying structure of the present invention, the drainage holes are formed in the support base component so that rainwater and the like that have entered the support base component can be discharged. However, when the support block sinks due to the weight of the concrete block when the concrete block is laid, there is no fear that the drain holes formed in the support block constituent member will be blocked.
