BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting block used in combination with a concrete block, a brick, a block of a sill, etc.

[0002]

2. Description of the Related Art Conventionally, concrete blocks, bricks and the like have been used as structures for constructing walls, foundations, flower beds, etc. However, as they are, the appearance may be terrifying and spoil the appearance. Therefore, a decorative concrete block with a watermark pattern is fitted as an accent to an appropriate portion of a structure such as a wall.

[0003]

However, since the decorative concrete block is limited in shape in terms of strength and safety, it is not possible to obtain satisfactory design. On the other hand, it is conceivable that a fitting block formed by casting the rectangular frame-shaped block main body with a design is formed, but the joint strength between the metal block main body and the mortar of the joint of the block fence cannot be expected, and it is assembled. There was a problem in strength and safety after loading.
In addition, when the fitting blocks are stacked adjacent to each other, the strength is further lowered, so that it cannot be used in a wide range of applications.

[0004] Therefore, an object of the present invention is to provide a metal fitting block which has a high joint strength after being assembled and is easily and excellent in the joint strength even when it is assembled adjacently.

[0005]

In order to achieve the above object, the present invention takes the following means. That is, the feature of the present invention is that the rectangular frame-shaped block main body is provided with protrusions on both outer surfaces at both sides, which are approximately the same height as half the joint width when the blocks are assembled, and the protrusions also penetrate the block main body. The point is that a through hole is provided.

Further, a protrusion having a height approximately the same as the joint width when the blocks are assembled is provided on the outer surface of the lower portion of the block body, and a through hole that penetrates through the block body is also provided in the protrusion, and the protrusion is provided above the block body. The point is that a through hole is provided at a position corresponding to the through hole. Further, a protrusion having substantially the same height as the joint width half when the blocks are assembled is provided on the upper and lower outer surfaces of the block body, and a through hole that penetrates the block body is also provided in the protrusion.

[0007]

In the present invention, the protrusion is embedded in the joint mortar and the mortar is embedded in the through hole.
As shown in FIGS. 9 and 10, since reinforcing members such as reinforcing bars, bolts and bent wires can be inserted, the bonding strength after assembling can be improved. Further, since the left and right heights and the upper and lower positions of the protrusions and the through holes are provided at substantially the same position so as to correspond to the case where the metal fitting blocks are vertically and horizontally stacked, the adjacent positions are In the case of stacking with each other, the adjacent through holes can be easily connected by simply fixing them with fixing means such as bolts and nuts, and the protrusions form a gap having a width substantially the same as the joint.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of a metal fitting block 1 according to the present invention. The metal fitting block 1 is a rectangular frame-shaped block substantially equivalent to two ordinary concrete blocks 2. It has a main body 3. Then, on the outer surface of both sides of the block body 3, there are two first projections 4 and 4 which have almost the same height as the joint width half when the blocks are assembled, and are vertically spaced from each other in two places and in the center in the thickness direction. The first protrusions 4, 4 are provided with a first through hole 5 that also penetrates the block body 3. The left and right height positions of the first protrusion 4 and the first through hole 5 are provided at substantially the same positions so as to correspond to the case where the block bodies 3 are stacked adjacent to each other in the left-right direction. .

Further, on the outer surface of the lower portion of the block body 3, the second protrusions 6 having a height substantially the same as the joint width when the blocks are assembled,
6 are provided at right and left intervals and are provided at the center in the thickness direction, and second projecting portions 6, 6 are provided with second through holes 7 that also penetrate the block body 3. Furthermore, the block body
A third through hole 8 is provided at a position corresponding to the second through hole 7 above the third hole 3.

The inside of the block body 3 is provided with a design 9 to give the structure after assembly a good appearance and increase the strength of the block body 3 itself. The design 9 can be modified as appropriate. This metal fitting block 1 is integrally molded by casting and has better mechanical strength than concrete ones, and it is about 3 in weight compared to the conventional concrete block 2 which weighs 20 kilograms.
The weight can be reduced to 1/6 kg, and the same shape can be easily mass-produced.

Next, the stacking state using the metal fitting block 1 will be described with reference to FIGS. 2 and 3, where the metal fitting block 1 and the conventional concrete block 2 are assembled at appropriate locations on the block wall 10. Mortar 13 is used for stacking in the same manner as stacking. At this time, the first and second protrusions 4,
6 is buried in the joint mortar 13 and the first, second,
Since the mortar 13 is also embedded in the third through holes 5, 7, 8, the joint strength can be improved.

At this time, as shown in FIG.
Into the second and third through holes 5,7,8, a joining reinforcing member 14 in which a piece of wire is bent in the middle can be inserted, or
As shown in FIG. 10, since the joining reinforcing member 14 in which the end portion of the reinforcing bar extending upward or downward is bent can be inserted into the first through hole 5, a strong joining can be achieved.

FIG. 4 shows a state in which the metal fitting blocks 1 are vertically adjacent to each other and assembled. In this case,
Insert the bolt 11 into the second and third through holes 7 and 8 that are vertically adjacent to each other, and use the nut 12 to insert the upper and lower metal fitting blocks.
By fixing 1 only, the second protrusion 6 forms a gap having substantially the same width as the joint. In other joints, the first and second protrusions 4 and 6 are embedded in the mortar 13 and the mortar 13 is embedded in the first through hole 5 as in the case of FIG.

FIG. 5 shows a state where the metal fitting blocks 1 are laterally adjacent to each other and are stacked. A joint reinforcing member 14 such as a reinforcing bar or a bolt can be inserted into the second through hole 7, and a stronger joint can be achieved. Since other configurations and effects are the same as those in FIG. 4, the same reference numerals are used and description thereof is omitted. FIG. 6 shows a second embodiment of the present invention,
Two protrusions 16 and 16 having approximately the same height as the joint width half when the blocks are assembled are provided at two places on the four outer surfaces of the rectangular frame-shaped block body 3 at intervals. A through hole 15 is also provided to penetrate the block body 3. The left and right heights and the upper and lower positions of the protrusion 16 and the through hole 15 are provided at substantially the same positions so as to correspond to the case where the block main bodies 3 are vertically and horizontally adjacent to each other and stacked. There is.

The construction using the metal fitting block 1 can be performed in the same manner as in the first embodiment. When the metal fitting block 1 is provided on the uppermost stage of the block wall 10, the upper projection 16 may be removed by post-processing, and the metal fitting block without the upper projection 16 at the time of casting. 1 may be preformed.

FIG. 7 shows a third embodiment of the present invention in which the thickness of the metal fitting block 1 is formed to be almost the same as that of the conventional concrete block 2 and the projections 4 are also provided in two places in the thickness direction. It is provided at intervals. Further, FIG. 8 shows a state in which the thickness of the metal fitting block 1 is reduced and the metal fitting block 1 is fitted on both front and back sides of the block wall 10.

The present invention is not limited to the above embodiment, but can be used in combination with a masonry wall or the like. In addition, the size of the rectangular frame of the block body 3 is
It may be one conventional concrete block or a plurality of conventional concrete blocks. Further, as shown in FIG. 5, it is possible to improve the joint strength by providing the insert leg 18 at the bottom of the block body 3 during casting.

[0018]

EFFECTS OF THE INVENTION According to the present invention, the protrusion provided on the side surface of the block body is embedded in the mortar of the joint such as the block wall, and the mortar is embedded in the through hole, or the reinforcing bar, the bolt or the bend is formed. Since a joining reinforcing member such as a wire can be inserted, the joining strength after assembling can be improved.
Further, since the left and right heights and the upper and lower positions of the protrusions and the through holes are provided at substantially the same position so as to correspond to the case where the metal fitting blocks are vertically and horizontally stacked, the adjacent positions are When they are stacked together, they can be connected simply by fixing them to the adjacent through holes with fixing means such as bolts and nuts, and since the protrusions form a gap of about the same width as the joint, it is extremely easy. Can be stacked.
