Description

[Detailed description of the invention] [Industrial application field] This invention has a steel plate placed inside a concrete block (hereinafter also referred to as a block), and a cutout groove for horizontal reinforcing bars formed within the block. This invention relates to a concrete block in which the strength of the block itself and the wall surface of the block constructed by loading the block has been strengthened.

[Conventional technology]

As shown in FIG. 6, a conventional concrete block 1' consists of two wall plates 2' spaced apart from each other and a connecting plate 3' connected between the two wall plates 2'. , move the block up and down,
It is used as partitions, gates, walls, etc. of various buildings by connecting it from side to side, or it is used as a structural wall of low-rise buildings as a reinforced concrete block by placing reinforcing bars in the cavity 6' and pouring concrete.

When manufacturing a block, a molding form consisting of a mold is usually set, concrete is poured into the form, hardened, removed from the mold, and cured to become a product.

[Problem that the invention attempts to solve]

The conventional concrete blocks mentioned above have a limit to their own strength, and cannot be used in cases where excessive weight is applied or where excessive strength is required for the walls, such as in mid-rise or high-rise buildings. As for structural walls, even if the blocks were reinforced with reinforcing bars, there were problems in terms of strength. The use of blocks to form building walls has many advantages, such as being easily accomplished by block masonry and eliminating the need for on-site construction work such as temporary framing using essential frames. , the appearance of blocks as strong structures was expected.

Also, in the setting and demolding of the molding form in the manufacturing stage of conventional concrete blocks, especially in the formation of the hollow part existing inside the block, it is difficult to form the hollow part. There were also problems with mass production of blocks, such as the middle frame being difficult to remove.

Furthermore, although not shown, even if a concrete block has recesses for arranging transverse reinforcement, when arranging multiple reinforcing bars, it takes a great deal of effort to specify the placement positions and set the spacing distances. I was forced to perform an impossible work process.

This invention was made to solve the problems of the conventional concrete blocks mentioned above.
In addition to arranging iron plates inside the block, in particular, in the case of the present invention, notch grooves for horizontally installing reinforcing bars are formed in the connecting plate, so that when loading the block, not only vertical reinforcing bars but also horizontal reinforcing bars can be installed as needed. The horizontal reinforcing bars can be placed in the specified position extremely reliably and easily, and the lateral connectivity becomes even more reliable and strong when concrete is filled.The strength of the block itself is significantly increased, and the block masonry gazette The structure is simplified, and the constructed block wall surface becomes strong, expanding the range of applications of the block structure wall, and simplifying the formwork, formwork setting, and mold removal processes in the mass production stage of blocks. The purpose of this project is to provide concrete blocks that are durable.

[Means for solving problems]

The above-mentioned problem arises when a concrete block is made up of two wall plates spaced apart from each other and one or more connecting plates connected between the wall plates. The present invention is solved by a concrete block characterized in that a cutout groove is formed therein, and iron plates are disposed on the back surface of the connecting plate and on the circumferential surface of the connecting plate.

〔Example〕

Hereinafter, the configuration of the present invention will be explained in detail based on examples.

FIG. 1 is a perspective view showing one embodiment of the concrete block of the present invention, and the concrete block 1 includes two (or one or more than two) concrete, mortar, etc. A connecting plate 3 made of a hard material is integrally connected between wall plates 2 made of a hydraulic substance such as concrete or mortar, and the wall plates 2 face each other substantially parallel to each other with a constant interval between them. 1
A cavity 6 is formed in. The connecting wall 3 is provided with a cutout groove 4 for horizontal reinforcing bars having a width corresponding to at least the thickness of the reinforcing bars so that reinforcing bars can be easily placed in the horizontal direction when loading the blocks 1. ,
It is formed. Although the cutout grooves 4 are formed in two places each on the top and bottom of the connecting plate 3 in FIG. 1, they may be formed only in the upper part or only in the lower part, and the number is limited to two. It is not limited to one location, but may be one location or multiple locations, such as three locations.

Then, concrete block 1 has wall plate 2.
An iron plate 5 is provided on the back surface of the concrete block 1 and on the outer peripheral surface of the connecting plate 3, thereby forming a cavity 6 in the concrete block 1.

The iron plate 5 is manufactured in advance from a shaped steel, a drawn steel pipe, a thin iron plate, etc. by means such as press forming or sheet metal processing, and at the concrete block forming stage, the iron plate 5 is set in a formwork and then The concrete block 1 is completed by integrating the rear concrete and the iron plate 5.

FIG. 2 is a perspective view showing another embodiment of the concrete block 1 of the present invention, and FIG. 3 is a side view of FIG. 2. The upper end 3a of the connection plate 3 is connected to the wall plate 2
The lower end 3 of the connecting plate 3 is protruded from the upper end 2a and
b is recessed from the lower end 2b of the wall plate 2, and the depth of the recess at the lower end 3b of the connecting plate is equal to the height at which the upper end 3a of the connecting plate 3 is protruded from the upper end 2a of the wall plate 2. Alternatively, the height may be slightly higher than that height. However, as shown in FIG. 4, when loading blocks, the upper end 3a of the convex connecting plate 3 of the lower block is fitted into the lower end 3b of the concave connecting plate 3 of the upper block. This prevents the blocks from shifting in position during construction, and allows the block assembly process to be performed firmly and accurately with improved work efficiency.

Incidentally, FIG. 4 shows a state in which reinforcing bars 11 are placed horizontally in the notch 4 and filled concrete is connected vertically and horizontally via the cavity 5 and the notch 4. Furthermore, FIG. 5 shows an embodiment in which a hollow portion 5 is formed in the connecting plate 3, and FIG. 6 is a side view of FIG. 5.

A step 7 is provided inwardly on the upper edge for connecting the blocks, and the depth of this step 7 is approximately equal to the thickness of the lower end 2b of the wall plate 2, and the height of the step 7 is Correspondingly, the lower end 3b of the connecting plate 3 is recessed from the lower end of the wall plate 2.

However, when the blocks are loaded, as shown in FIG.
The lower end 2b of the block located above is fitted,
More than in the case of the embodiment shown in Fig. 2, it is possible to prevent the blocks from shifting when they are loaded, and it is also possible to pour filling concrete, mortar, etc. all at once after the blocks have been stacked empty. The process is performed robustly, accurately, and with improved work efficiency. In addition,
The stepped portion 7 eliminates the need for side joint mortar when joining the blocks, and also prevents rainwater and the like from entering the inside of the blocks.

Note that FIG. 5 shows a state in which the reinforcing bars 10 are placed in the cutout grooves 4 and filling concrete is poured.

In addition, in the concrete block of the present invention, as shown in FIG. 2, decorative patterns 8 such as curves, straight lines, graphic shapes, etc., or surface irregularities are formed on the surface of one or two wall panels 2. As shown in Fig. 4, by attaching decorative exterior members 9 such as tiles or stones, a solid block structure wall surface with a beautified exterior is completed as soon as the block loading work is completed. It is.

The dimensions of the wall plate of the concrete block of this invention are JIS standard dimensions (length 390 mm x height 190 mm).
It may be of a larger size. If it is a large concrete block,
When constructing a block wall surface, the number of blocks to be assembled is reduced, and the construction labor is reduced.

[Functions and effects of the invention]

The concrete block of the present invention having the above structure has high-strength iron plates arranged on the back side of the wall plate of the concrete block and on the circumferential surface of the connecting plate, so the block itself has a significantly higher strength than conventional blocks. In addition to being strong, when constructing a wall by loading blocks, the steel plates play the role of reinforcing bars by pouring concrete into the cavity of the block, compared to the case where reinforcement is placed on conventional blocks. Therefore, it is possible to construct a block wall having the same or higher strength, and the applicability of the concrete block of the present invention is greatly expanded.

In other words, when using the concrete blocks of the present invention as partitions, gates, fences, etc. of various buildings, it is possible to construct block walls that are significantly reinforced compared to conventional ones, and the work efficiency is improved by omitting reinforcement work. Furthermore, when placing reinforcing bars in addition to pouring concrete into the blocks of the present invention, the connecting plates have cutout grooves for horizontally installing reinforcing bars, so the transverse bars can be placed in the notched grooves. By fitting, the horizontal reinforcement does not move and is placed in a uniformly determined position in any block, making the work of arranging the horizontal reinforcement extremely easy and easy. This makes it possible to arrange the transverse bars in the best possible condition, regardless of the skill level of the person. In addition to the lateral connectivity of the concrete through the notched grooves, the lateral blocks are firmly and integrally connected by the arrangement of the horizontal reinforcements, and the filling concrete injected into the cavity of the block is Alternatively, vertical reinforcing bars may be added to the cavity as necessary to connect the loaded block walls in the vertical and horizontal directions to provide strength. For this reason, the concrete block of the present invention can be used as a structural wall of not only low-rise buildings but also medium-rise and high-rise buildings, as well as other wall structures that require high strength.

Furthermore, in manufacturing the concrete block of the present invention, the iron plate of the concrete block of the present invention can be used as the middle frame in the forming form, and the middle frame may be omitted, or even if the middle frame is Even if the inner frame is required, the inner frame can be extremely simplified, so advantages such as a reduction in the cost of the formwork due to the simplification of the formwork, a simplification of the demolding process, and an increase in block production efficiency can be realized. It is something that
