Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method of stacking concrete blocks (hereinafter also simply referred to as blocks) using only reinforcing bars without using any joint material such as mortar, and then stacking them on top. This invention relates to a concrete block in which mortar or concrete is injected into the cavity of the block and then cured in one piece, thereby forming a part corresponding to a normal joint between adjacent blocks to firmly connect them, and a method of constructing the block. .

[Prior Art] A conventional concrete block 1' has a structure as shown in FIG. That is, a vertically open cavity 4' is provided between the front wall 2' and the back wall 3', which are generally symmetrical to each other, and the front wall 2' and the back wall 3'
The upper end surface, lower end surface, one side end surface 5', and the other side end surface 6' form a single plane so as to be in close contact with other adjacent blocks. For this reason, as shown in Figure 7, these blocks 1' are constructed using both vertical reinforcing bars 7' and horizontal reinforcing bars 8', and mortar is always used during the masonry work. Adjacent blocks are glued and fixed together using a joint material 9' such as, and after a predetermined period of time, when the joint material 9' has hardened to some extent, mortar or concrete is injected and filled from the uppermost cavity. However, methods were taken to ensure the solid strength of the final architectural structure.

[Problems to be Solved by the Invention] Conventional concrete blocks having the above-mentioned configuration and construction methods using the concrete blocks have the disadvantage that each block may move in parallel with adjacent blocks during masonry. Each time the blocks were stacked, it was necessary to successively apply a joint material such as mortar to secure them in place. In the construction method using blocks having such a structure, it is necessary to apply joint material to all joint surfaces between the blocks, which requires a great deal of effort, time, and skilled work. In other words, extremely precise dimensional accuracy was required for joint materials such as mortar, which were all applied by hand, and as a result, the people who performed these tasks required considerable craftsmanship. be. Furthermore, it was not possible to inject fillers such as mortar or concrete until the joint material had hardened to a certain extent to ensure contact strength, and many problems remained in terms of workability and construction time. .

[Means for Solving the Problems] The present invention has been made to solve the various problems as described above. In a concrete block mainly used as a wall constituent material of architectural structures, which is composed of a plurality of connecting walls interposed between the concrete blocks and forms a cavity penetrating vertically between the connecting walls, the connecting walls are connected to each other. A notch is provided on the upper surface of the connecting wall, and a recess and a convex portion that engage with each other are provided on each left and right end surface and each upper and lower end surface of the front wall and the back wall, and a recess and a convex portion are provided on each of the upper and lower end surfaces. The convex portion abuts and engages only at the edge portions of the front and rear walls when stacked, and there is a cavity between the connecting walls between the upper and lower end surfaces of the front wall and the back wall excluding the edge portions of the front wall. It consists of a concrete block characterized by having a space in communication with the concrete block, a front wall, a back wall, and a plurality of connecting walls interposed between the front wall and the back wall, and between the connecting walls. In a construction method for a concrete block, which is mainly used as a wall component of architectural structures, and which has a cavity that penetrates vertically through the concrete block, a notch is provided on the upper surface of the connecting wall to communicate with the connecting wall, and The left and right end faces and the upper and lower end faces of the front wall and the back wall are provided with recesses and protrusions that engage with each other, and the recesses and the protrusions on the upper and lower end faces are provided on each surface side of the front wall and the back wall when stacked.

This problem is solved by the construction method.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

1 shown in FIG. 1 is a concrete block according to the present invention, and this concrete block 1
is a mutually symmetrical whole wall 2, back wall 3, and this front wall 2
and a back wall 3, and two connecting walls 4b for providing a vertically open cavity 4 which also has the function of accommodating vertical reinforcing bars. And, on the upper end surface of each of the front wall 2 and the front wall 3,
Step portions 2a and 3a forming substantially step-like recesses are provided at the edge portions on the front wall surface side and the edge portions on the rear wall surface side, respectively, and form substantially step-like recesses so as to descend toward the front wall surface side, and the front wall 2,
The lower end surface of each back wall 3 has an edge portion on the front wall surface side and an edge portion on the back wall surface side, respectively, in order to abut and engage with the step portions 2a and 3a described above when the concrete blocks 1 are stacked. Step portions 2b and 3b forming substantially step-like convex portions are provided so as to descend toward the bottom. Then, the stepped portions 2b and 3b of these convex portions
The depth of the recessed portion is set to be greater than the depth of the stepped portions 2a and 3a of the recessed portion.

On the other hand, regarding the left and right end faces of the concrete block 1, one side end face 5 (right side in this embodiment),
The other side end surface 6 (left side in this embodiment) is
The concave portion 5a and the convex portion 6 are arranged so that they abut and engage with other adjacent blocks without being displaced from each other.
It forms a.

Further, 4a is a notch provided on the upper surface of the connecting wall 4b for arranging horizontal reinforcing bars, and by making this notch 4a approximately V-shaped, the horizontal reinforcing bars can be placed in this notch. By simply placing the reinforcing bar in the notch 4a, the reinforcing bar is automatically placed approximately in the center between the front wall 2 and the back wall 3.

Next, an example of construction of the concrete block 1 mentioned above will be explained. That is, as shown in FIGS. 2 to 5,
A large number of concrete blocks 1 are assembled using vertical reinforcing bars 7 and horizontal reinforcing bars 8 without using joint material such as mortar, and when all the masonry is completed, the hollow part at the top of the masonry is 4, a filling material such as mortar or concrete is injected (placed) all at once, thereby ensuring the desired solid strength.
A part of this filler is formed in the preset concave step portions 2a, 3a and the convex step portions 2b, 3b.
It enters the gap 9 formed by the size difference between the
This filling material in the gap 9 can function as a joint material in conventional construction methods.

In addition, 10 is the concrete block 1 of the present invention.
This is a connecting metal fitting (for example, one consisting of a long bolt, nut, washer, etc.) used when building a wall in the form of a wall with a T-shaped or square-shaped connection part.

In particular, in the embodiment shown in FIG. 5, concrete is poured into the ceiling of a room-like structure, that is, the floor 11 of the second floor, and the hollow part of the block is filled at the same time. This can significantly shorten the construction period.

[Operations and Effects of the Invention] As described in detail above, according to the present invention, recesses and protrusions for fitting other concrete blocks into each other are provided on the left and right side end faces and the upper and lower end faces of the concrete block, and in particular, the front wall and the convex part are provided. When the upper and lower end surfaces of the back wall are stacked, although the front side edge portions are abutting and engaging, there is no vertical penetration between the upper and lower end surfaces of the front wall and the back wall excluding this front side edge portion. A gap is provided that communicates with the cavity between the connecting walls. As a result, after a wall-like structure is formed by building up only concrete blocks (of course reinforcing bars are used in conjunction with conventional methods) without using joint materials such as mortar, mortar and By injecting the filler such as concrete all at once, a portion of the filler also flows into the space between the upper and lower blocks. The filler that has flowed into this gap plays the role of joint material in conventional block construction, so the strength of the completed structure is comparable to that of conventional structures, and the filling material is used as a joint material in conventional block construction. Since there is no need to fill, the construction period is extremely short, and even in relatively large structures, all the joints are filled at once by injecting the filler, resulting in high-quality structures. can do.

In addition, by connecting multiple connecting walls and providing a notch on the top surface of the connecting wall, reinforcing reinforcing bars can be installed by simply placing horizontal reinforcing bars in the notches without requiring any special fixing members. It can be placed at a fixed position and has excellent workability.

Furthermore, according to the present invention, unlike conventional masonry work in which joint material is applied, only the blocks are laid down as if they were building blocks, so special skill is not required in the masonry work. This makes it possible to provide a concrete block that has various excellent properties, such as a concrete block that is free from damage, and a construction method using the concrete block.
