[Industrial applications]

 The present invention relates to a concrete block body, and more specifically to a concrete block body having an inverted T-shaped cross section, which is suitable for a foundation wall for attaching and fixing a fence, a fence, etc. to an upper part, or a foundation of a structure such as a house. .

[0002]

[Prior art]

 Conventionally, wooden fences and block fences have been widely used as residential fences, and the foundation for building a house is to install a concrete frame at the site and then pour raw concrete into the frame. It is constructed by solidifying in.

However, since the facility of the board fence is constructed by first setting up a column for fixing (with a groove) and then inserting the plate materials one by one into it, it takes a lot of time and work time. Of course, the strength after completion was not enough, and there was a risk of collapse if a strong shock such as an earthquake was received.

In addition, since the facility of the block fence is constructed by sequentially stacking a number of small rectangular parallelepiped blocks vertically and horizontally, it takes time and labor, and in addition, the accuracy of the alignment and stacking is high. Since it is required, it is the actual situation that technical skill was required for the construction, and the strength was not sufficient. Rather, it was vulnerable to shocks such as earthquakes because it was piled up, and it easily collapsed. There was a danger to say.

Further, in the foundation construction using the ready-mixed concrete method, it is unavoidable that it takes a lot of time to install the frame and the working time becomes long, and that it takes a long time to dry and solidify the ready-mixed concrete. .

[Problems to be solved by the device]

 Therefore, the present inventor has conducted various studies with the aim of eliminating the inefficiency of such conventional facility construction and providing a fence and foundation with excellent earthquake resistance. The present invention has devised a concrete block body of the present invention, which can perform facility work extremely efficiently by machine work using a machine, etc. and can install a stable and solid fence and foundation.

[0007]

[Means for Solving the Problems]

 That is, the present invention is a cross-sectional view of a horizontal base portion having at least one mortar filling hole for joining and fixing it to soil concrete, and a standing wall portion having a steel bar projecting into the mortar filling hole at its lower end. It is a concrete block body characterized by being integrally molded in an inverted T shape.

In the present invention, it is sufficient that at least one mortar filling hole of the horizontal base portion used for fixing the joint with the soil concrete is formed so as to penetrate at least in the central portion of the horizontal base portion. Furthermore, it is advantageous to form notch-shaped mortar filling holes at both ends of the horizontal base part in order to strengthen the joint and fixation with the soil concrete.

The mortar filling hole may have any shape such as a square shape or a circular shape as long as it has an opening that vertically penetrates the horizontal base portion and has an opening that is not blocked by the standing wall portion. .

In addition, it is desirable that the standing wall portion is formed with positioning notches, for example, wedge-shaped notches, at both upper end corners when connecting and using a plurality of concrete blocks of the present invention.

[0011]

【Example】

 The present invention will be further described below with reference to the drawings illustrating the embodiments.

1 to 4 showing the first embodiment, reference numeral 1 is a horizontal base portion made of a flat rectangular parallelepiped which is a grounding portion, and mortar filling holes 11a and 11b for joining and fixing with the soil concrete 3. , 11c are formed in total at the center and both ends.

Each of the mortar filling holes 11a, 11b, 11c is a rectangular hole having an opening that vertically penetrates the horizontal base portion 1 and that the opening portion is not blocked by the standing wall portion 2. The central filling hole 11a is a complete through hole, and the end filling holes 11b and 11c are notched holes having openings not only in the upper and lower sides but also in the side end faces.

Reference numeral 2 denotes an upright wall portion made of a flat rectangular parallelepiped, and steel frame rods 21a, 21b, 21c projecting into the mortar filling holes 11a, 11b, 11c are suspended and fixed to the lower end portions thereof.

Further, wedge-shaped notched grooves 22 for positioning when a plurality of concrete blocks of the present invention are connected and used are formed at both upper end corners of the standing wall portion 2.

Thus, the horizontal base portion 1 and the standing wall portion 2 as described above are a block body integrally formed by a concrete product having an inverted T-shaped cross section.

The size of such a block body is appropriately selected according to the installation place and the purpose, but usually the horizontal base 1 is 40 to 80 cm in width, 100 to 200 cm in length, and 10 to 10 in thickness. It is preferable that the height is 30 cm and the standing wall portion 2 has a thickness of 5 to 20 cm, a width of 100 to 200 cm, and a height of 50 to 200 cm.

Incidentally, when the present invention is carried out as a base wall for mounting and fixing a fence, as shown in FIG. 5 showing the second embodiment, the height of the standing wall portion 2 is set to about 20 to 100 cm and its upper end portion is set. A fence stop column 23 and a fence 24 such as a wire mesh may be attached and fixed to the.

[0019]

[Advantages] Since the present invention is configured as described above, in order to install a fence or the like, first dig a hole in the installation location, spread cobblestone, crushed stone, etc. An appropriate number of steel frame rods 31 connected to the steel frame 32 are set up so that they can be inserted into the mortar filling holes 11a, 11b, 11c of the horizontal base 1. Then, fresh concrete is poured and solidified to form the soil concrete 3. While aligning the mortar filling holes 11a, 11b, 11c with the steel bar 31 which has been erected, a required number of concrete block bodies of the present invention are successively connected and installed by a crane or a power shovel. When the connecting alignment notch 22 is present, the notch 22 is filled with mortar to strengthen the connection between the block bodies. After that, mortar is poured into and filled in each of the mortar filling holes 11a, 11b, and 11c, and the horizontal base 1 is bonded and fixed to the soil concrete 3 to complete the installation work of the fence and the like.

[0020]

[Effect of device]

 Therefore, according to the present invention, facility work can be performed extremely efficiently by mechanical work, and the fences and the like installed are extremely stable and solid, and have excellent earthquake resistance.

In particular, since the concrete block body of the present invention has an inverted T-shaped cross section, it has excellent stability compared to an L-shaped block, and can be made symmetrical, resulting in moldability and facility construction. The workability is also good, and it is convenient when the landowners who touch the boundary share the land and costs fairly.
