Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block wall and its construction method.

[0002]

2. Description of the Related Art Conventionally, a block wall is constructed by laying mortar joints between the blocks, and a professional craftsman applies mortar at each stage to level the blocks. On the other hand, the next block is mounted and the cavity is filled with mortar or concrete by filling.

[0003]

However, the shortage of manpower has recently become more and more serious, and it is not easy to secure particularly skilled craftsmen. In addition, when the blocks are assembled or when mortar or the like is placed and filled, the outer surface of the block, which is the vertical surface of the block wall, may become unsteady.
Even if I discovered this after the fact, I couldn't fix it anymore. Furthermore, generally, in the block wall body, the outer surface of each block and the mortar joint are finished to be substantially flush with each other, which is rather monotonous.

An object of the present invention is to eliminate such drawbacks and at the same time provide a block wall body having a required heat insulating structure.

[0005]

The block wall of the present invention comprises:
A building block with a concave groove on the upper end surface of the face shell and a downward protruding edge portion on the lower end surface has a downward protruding edge portion of the upper block in the concave groove of the lower block on the required foundation. They are fitted together and are torn and are laid in a desired stacking manner such as joints or potato joints. A synthetic resin layer formed by in-situ foaming of a foamable synthetic resin material is formed on at least one of the outer side surfaces of the blocks on both sides formed by the aggregated face shells of the building blocks. . Furthermore, the vertical cavity between the face shells is filled with mortar or concrete.

According to the method of constructing a block wall of the present invention, the above-mentioned building block is laid on a required foundation, and a downward projecting edge portion of the upper block is fitted into a groove of the lower block to form a joint or a broken joint. Assemble with the desired stacking method such as joints, and then
Forming a synthetic resin layer by in-situ foaming a foamable synthetic resin material on at least one of the outer sides of the blocks on both sides formed by the face shells of the building blocks that are assembled together, and, The purpose is to fill the vertical cavity between the face shells with mortar or concrete.

In the above-mentioned building block assembly, the lower projecting edge of the upper block is fitted in the concave groove of the lower block, and the vertical groove of one of the blocks adjacent to the left and right is connected to the vertical groove of the other block. By fitting the lateral protrusions, lateral gaps and vertical gaps, that is, vertical and horizontal joints are formed, and the overall three-dimensional and solid feeling is rich.

[0008]

According to the present invention, the positional displacement of each block is regulated within a required range by fitting the concave groove and the downward projecting edge portion and further fitting the vertical groove and the lateral projecting edge. In addition, the synthetic resin layer formed on the outer surface of the block fixes each block, so even if mortar or concrete is poured into the vertical cavity between the face shells, each block will be displaced due to that. There is nothing to cause. For this reason, even if you are not a professional craftsman, you can easily construct the desired block wall, and if you are an original craftsman, compared to the conventional case where each block is sequentially fixed with mortar etc. The work efficiency can be remarkably improved.

The synthetic resin layer formed on the outer surface of the block not only prevents the blocks from being displaced during the construction, but also makes the block wall body a heat insulating structure.

EXAMPLE A building block a used in the present invention
Is made of ceramic porcelain, and as shown in FIGS. 4 to 6, the face shells 1, 1 on both sides are connected by the connecting portions 2, 2, and a vertical cavity b is formed between these connecting portions 2, 2. , Vertical cavities b ', b'on the outside of the connecting portions 2, 2.
Is formed.

The face shells 1, 1 are composed of an inner bearing portion 3 and an outer decorative portion 4. Further, the inner proof portion 3 is composed of an inner wall portion 5 and an outer wall portion 6, and the outer wall portion 6 is a portion located between the outer decorative portion 4 and the inner wall portion 5. The upper end of the outer wall portion 6 is lower than the upper end surfaces of the outer decorative portion 4 and the inner wall portion 5, and a concave groove 7 is formed therein, and the lower end of the outer wall portion 6 has lower end surfaces of the outer decorative portion 4 and the inner wall portion 5. A downward projecting edge portion 8 that projects further is formed. The protruding length of the downward protruding edge portion 8 is approximately 2.5 times the depth of the concave groove 7. The outer wall portion 6
The left end of which is recessed from the left end surfaces of the outer decorative portion 4 and the inner wall portion 5 to form a vertical groove 9 therein, and the right end of which extends laterally from the right end surfaces of the outer decorative portion 4 and the inner wall portion 5. Edge 1
Forming 0. The projecting length of the lateral projecting edge portion 10 is approximately three times the depth of the vertical groove 9.

In order to construct the block wall A by the building block a having the above-mentioned construction, the block a is passed through the vertical reinforcing bars c in appropriate vertical cavities b and b'on a required foundation, for example, the breakage shown in FIG. It is constructed by adopting a desired stacking method such as ground or potato joints. At this time, the downward projecting edge portion 8 of the upper block a is fitted into the concave groove 7 of the lower block a and adjacent to the left and right. Of the blocks to be formed, the lateral protruding edge portion 10 of one block a is connected to the vertical groove 9 of the other block
Fit and stack. This stacking is performed, for example, while horizontally mounting the horizontal reinforcing bars d on the connecting portions 2 and 2 of every other block a.

Each of the stacked blocks a is manufactured with high accuracy in the above-mentioned structure, so that the corresponding parts are horizontal and the both sides are horizontal by simply sequentially fitting the corresponding parts as described above. The surfaces of the face shells 1 and 1 of (1) are made to be vertical, but if there is an inward / outward movement in or out of the surface, that is, unevenness, it is corrected if necessary. In this case, since each block a is not fixed with mortar or the like unlike the conventional block, the unevenness can be easily corrected.

When the blocks a are simply stacked in this way, the face shells 1,
Since the protruding length of the downward projecting edge portion 8 projecting from the lower end surface of the concave groove 7 formed in the upper end surface of the outer peripheral surface 1 is approximately 2.5 times, the outer decorative portion 4 of the upper block a is A required lateral gap h (10 mm) is maintained between the lower end face of the block and the upper end face of the lower block a. Also, face shell 1,
Since the protruding length of the lateral projecting edge portion 10 projecting from the right end surface is approximately three times the depth of the vertical groove 9 formed on the left end surface of No. 1, the outer decorative portion 4 of the blocks a, a adjacent to the left and right. A required vertical gap i (10 mm) is maintained between the left and right end faces of the.

Subsequently, the foamable synthetic resin material is applied to at least one of the outer side surfaces of the blocks on both sides formed by collecting the face shells 1, 1 of the building blocks a stacked as described above. In-situ foaming is performed to form a synthetic resin layer 11 having a required thickness (FIGS. 1 and 2). This synthetic resin layer 11
Partially penetrates into the minute gap between the concave groove 7 and the downward projecting edge portion 8 which are meshed with each other through the lateral gap h, and is likewise meshed with each other through the longitudinal gap i. It is also made to enter into the fine gap between the vertical groove 9 and the laterally projecting edge portion 10 and hardened while covering the outer side surface of the block to fix each block of the stacking.

Incidentally, the lateral gap h may be filled with mortar in advance and pressed.

As a result, each block a is integrated into a state in which its inner space, that is, the vertical cavities b, b ', b', is not displaced even when mortar or concrete is poured and filled, so that each block a is integrated. a face shell 1,
Mortar or concrete e is placed between the first and second vertical cavities b, b ', b', as well as the lower end surface of the inner wall portion 5 of the inner bearing portion 3 of the upper block a and the inner bearing portion 3 of the lower block a. Of the inner wall portion 5 of the inner bearing portion 3 of the blocks a, a that are adjacent to each other on the left and right sides, as well as the upper end surface of the inner wall portion 5 and the downward protruding edge portion 8 of the upper block a. Mortar or concrete is also filled into the inward vertical recess g formed by the left and right end faces and the lateral projecting edge portion 10 so as to surround them.

With this, the desired block wall A can be constructed. However, since the synthetic resin layer 11 also functions as a heat insulating layer, the block wall A is necessarily a heat insulating structure. Therefore, it is also clear that depending on whether the synthetic resin layer 11 is formed on the outer side surface or the inner side surface of the block wall body A, the outer heat insulating structure or the inner heat insulating structure is obtained.

The block wall A is a block a in the upper stage.
Lower end surface of the inner wall portion 5 of the inner load bearing portion 3 and the lower block a
Since the upper end surface of the inner wall portion 5 of the inner load bearing portion 3 and the downward projecting edge portion 8 of the upper block a surround the inward lateral concave portion f, and the mortar or concrete e is also filled therein as described above. In calculating the joint structure, it is possible to treat the load as acting on both the inner wall portion 5 and the outer wall portion 6, that is, the entire width of the inner proof portion 3.

On the side where the synthetic resin layer 11 is not formed, since the protruding length of the downward projecting edge portion 8 is approximately 2.5 times the depth of the recessed groove 7, the outer cosmetics of the upper and lower blocks a, a are formed. A required lateral gap h between the lower end surface and the upper end surface of the portion 4
Similarly, the lateral protruding edge portion 10 is deeper than the depth of the vertical groove 9.
Since the projecting length is approximately three times, the required vertical gap i is maintained between the left and right end surfaces of the outer decorative portions 4 of the blocks a, a that are adjacent to each other on the left and right.

By attaching a required finishing material 12 to the surface of the synthetic resin layer 11 as needed, the synthetic resin layer 11 itself can be protected and formed into a good appearance.
Therefore, it is preferable to embed a finishing material mounting bar or the like in the synthetic resin layer 11.

[0022]

As is apparent from the above description,
The present invention has the following effects.

By the fitting of the concave groove and the downward projecting edge portion, and further, the fitting of the vertical groove and the lateral projecting edge, the positional deviation of each block is restricted to a required range. The formed synthetic resin layer fixes each block, so even if the mortar or concrete is poured into the vertical cavity between the face shells, each block will not be displaced due to that. . For this reason, even if you are not a professional craftsman, you can easily construct the desired block wall, and if you are an original craftsman, compared to the conventional case where each block is sequentially fixed with mortar etc. The work efficiency can be remarkably improved.

The synthetic resin layer formed on the outer surface of the block not only prevents each block from being displaced during the construction, but also makes the block wall body a heat insulating structure.

On the side where the synthetic resin layer is not formed, a horizontal gap is formed between the upper and lower blocks, and a vertical gap is formed between the left and right blocks. It is rich in three-dimensional effect and solid feeling.
