Description

Description: TECHNICAL FIELD The present invention relates to a block structure building obtained by laying formwork concrete blocks.

2. Description of the Related Art In this type of formwork concrete block building, a block is laid on a foundation, reinforcement is given in the block, and then concrete is placed to construct a wall body. The floor between the partition bodies is mounted by placing concrete or PC concrete.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional formwork concrete block structure construction, horizontal loads in both the X direction and the Y direction are applied to load bearing walls in that direction, that is, concrete blocks in the same direction with respect to the X direction. The wall serves as a so-called wall-type structure in which a concrete block wall in the same direction as the Y direction supports the structure. Therefore, in such a structure, it is necessary to construct the wall body with a block wall having a horizontal resistance force in both the X direction and the Y direction. Therefore, in such a structure, it is necessary to construct a formwork concrete block wall with horizontal proof stress in any direction, and there are restrictions on the wall structure such as the position of the opening and the selection of materials, There is a drawback that a large opening cannot be taken. Or, for one of the X and Y directions,
A load bearing wall with an X-shaped brace can be used, but in this case it is exactly the same. In view of such a conventional example, the present invention provides a formwork concrete block structure wall in one of the X direction and the Y direction, and provides horizontal resistance by this wall body, and in the other directions, both walls By providing a horizontal bearing capacity by a frame structure composed of a concrete slab cast between the body and its wall, the conventional drawbacks are eliminated.

Means for Solving the Problems That is, in the present invention, a pair of parallel side wall portions facing each other, a formwork concrete block structure for placing concrete by laying reinforcing bars in a built concrete block In addition, the reinforcing bar reinforcement and the cast concrete of the concrete slab, which are placed so as to be laid between the side wall portions, pass through the openings formed in the concrete block, and There is provided a block structure building characterized in that the side wall portion and the slab concrete are jointed integrally so as to be continuous with the installed concrete, and the joint portion is a rigid joint.

Operation As mentioned above, in the direction perpendicular to the concrete block wall, horizontal load is supported by the frame structure consisting of a pair of wall bodies and concrete slabs, so it is not necessary to use bearing walls.

Example In FIG. 1, a pair of mutually parallel wall bodies (1) and (1) are constructed by form concrete blocks (2) and (2) ... As shown in FIG. The slabs (3) (3), which are installed between the bodies (1) and (1),
Blocks (2) (2) of both wall bodies (1) (1) are integrally cast into concrete to be cast into them to integrally connect the two, and thereby the wall bodies (1) (1) and In the direction at right angles, a rigid joint frame structure composed of both walls (1) (1) and a concrete slab (3) supports a horizontal load in that direction. (4) is the wall (1)
Roof material installed between the upper ends of (1), which is a PC
It may be concrete or the like.

As described above, since it is not necessary to support the horizontal load by the bearing wall in the direction perpendicular to the wall body (1), non-bearing walls (such as curtain walls) in the same direction, that is, the opening direction ( 5) can be used.

Next, a block (2) for constructing the wall body (1) (1)
The structure of (2) ... and the connection structure of the slab (3) and the wall body (1) will be described with reference to FIG. 2 and subsequent figures. Concrete blocks (2) (2) ... In the same manner as above, it has side walls (7) and (7) inside and outside the building and a pair of connecting parts (8) and (8) for connecting between the side wall parts (7) and (7). In the example, each side wall (7)
The bottom wall portion (9) is integrally formed continuously with the lower ends of (7) and the connecting portions (8) and (8), whereby the concave portion (10) opened in one vertical direction is formed into the connecting portion (8). ) (8)

The concrete blocks (2) (2) formed in this way are laid on an unillustrated foundation in a potato joint pattern. At this time, the direction of the recesses (10) is alternately inverted upside down. It is piled up like doing. At this time, the upward concave portion (10) of the lower block (2) and the downward concave portion (10) of the upper block (2) are aligned with each other, and these concave portions (10) (10) are united. The hollow portions (11) (11) ... Are formed in the wall bodies (1) (1). In the blocks (2), (2), etc. that have been laminated in this way, the vertical space (12) and the horizontal space (13) between the recesses (10) (10) ... are penetrated. Then, a reinforcing bar reinforcement consisting of a vertical bar (14) and a horizontal bar (15) is applied.

Further, in the slab (3) portion connected to the wall body (1), as shown in FIG. 5, depending on the width of the slab (3), for example, in this figure, one block (2) -
a) (2-a) ... the side walls (7) inside the building on both sides of the recess (10) are located further above the blocks (2-b) (2-b).
), The lower half portions of the side wall portions (7) on both sides of the recess (10) are each cut away to form a plurality of openings (16) (16) ... Between the recesses (11) (11). It Then, at the position where the concrete for the slab (3) is placed, the rebars (17) (18) in the X direction and the Y direction are arranged. Among them, the rebars in the erection direction of the slab (3) ( 17) (17) ...
Blocks (2) (2) from the openings (16) (16) ...
It extends to the inside and connects with the reinforcement in the block (2). Although not shown in the figure, a mold for the slab (3) is attached to this slab concrete pouring portion, and thus, as shown in FIG.
The concrete (19) and the slab (3) that are cast inside are integrally cast and integrally connected to each other, and the joint portion between the cast concrete of the wall body (1) and the concrete of the slab (3) Is a rigid frame structure.

The concrete (19) cast into the blocks (2) (2) ... is not filled in the hollow portions (11) (11) ... but is left as it is, and further in the slab (3) portion. However, the hollow portion (20) is formed, and both of them serve to reduce the weight of the building itself.

Effects of the Invention According to the present invention, the following effects can be obtained.

． Since the rigid body frame structure in which the block structure wall body and the slab are integrated is configured, the wall body in the direction perpendicular to the block structure wall may be a non-bearing wall such as curtain wool. There are no restrictions on the position of the parts or the constituent materials, and the design is free.

． Since the wall body of the block structure is a load bearing wall, it is not necessary to provide a load bearing wall in the same direction inside.

． Since the block structure wall can be constructed by a method of stacking blocks and filling with concrete, and the work can be performed from the inside of the wall body, it can be built close to the adjacent building.

． Also, the opening side in the direction perpendicular to the block wall can be left open at the stage of building work, and since there is no wall inside, the car can be driven into the building, and all the work is done inside the building. Can be installed.
