Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block laminated structure in which concrete blocks are arranged in advance in a laminated shape to form a panel body, and the panel is installed at a predetermined wall position to construct a wall body. It relates to a panel construction method.

2. Description of the Related Art As shown in FIG. 6, a large number of blocks (31) are arranged in a horizontal plane in advance, and each block is tightly connected by a steel rod (32) inserted through the block (31). Panel body (3
The method of constructing 3) and installing this panel body at a predetermined wall position is conventionally known (for example, Japanese Patent Publication No. 53-40009).
Issue). In this conventional block laminated panel (33), the blocks (31) are arranged at the joints and tightly connected by steel rods (32) (32) inserted in the vertical and horizontal directions.

Problems to be Solved by the Invention As described above, in the conventional block laminated panel (33), since the whole is a joint arrangement of potatoes, the steel rod (32) is inserted in the vertical direction, so that the horizontal direction can be improved. Because it separates
It is necessary to tightly connect the entire structure with the horizontal steel rods (32) as well, the number of steel rods (32) for fastening is increased, and a washer for that is also required, resulting in an increase in the number of parts and man-hours. Also has the drawback of increasing.

In this case, it is possible to reduce the number of steel rods (32) to some extent even if they are tightly connected in the vertical direction and the horizontal direction, but in that case, on the contrary, the blocks (31) are firmly connected to each other. Since it has to be bonded with a different adhesive, the work also requires a lot of work. In addition, when the steel rod (32) is tensioned from the longitudinal direction and the lateral direction to introduce the stress into the interior, it is necessary to manage the compressive stress from both the longitudinal direction and the lateral direction.

Furthermore, when the laminated panels (33) are arranged in series in the wall direction when arranged in the above-mentioned joint shape, when the panels (33) are brought into close contact with each other, a steel bar (32) becomes a horizontal streak of each panel (33).
They cannot be joined together. That is, even when the wall body is constructed by using the block laminated panel (33) as described above, it is necessary that the horizontal bars arranged in the block (31) are connected to each other. The work cannot be performed in reality, and there is a drawback that the panels must be installed apart from each other and the steel rods (32) must be connected to each other, and then the column concrete must be placed between them.

The present invention has been made for the purpose of eliminating these conventional drawbacks.

Means for Solving the Problems And, in order to achieve the above object, in the present invention, the layers are laminated in a tear joint shape without tearing the left and right ends of the tear joint joint. After a large number of concrete blocks (2) are tightly connected to each other to form a panel (20) and the panel (20) is installed at a predetermined installation location,
It is characterized in that a space (23) for one block (2) generated between each panel (20) is filled with each block (25) to form a continuous broken joint pattern.

Action The block laminated panel (20) arranged in a tear joint is
When these panels (20) are connected in the wall direction, a space (23) for one block (2) is formed between the panels (20), and the space (23) of this part is formed. Utilizing this, after connecting the horizontal stirrup (10) of both panels (20), each block (25) is filled.

EXAMPLE FIG. 2 is a perspective view showing a method for manufacturing a block laminated panel of the present invention. In the figure, (1) is a pallet installed on the ground at the site, and blocks (2), (2), etc. are arranged on this pallet (1) in a tear-and-joint shape to form a predetermined panel size. To (3) shows an opening portion such as a window or a doorway. Block (2) is a formwork concrete block, as shown in FIG.
An outer wall surface side having a thick wall formed of a pair of face shells (4) (4) in the wall thickness direction and a pair of connecting portions (5) connecting between the face shells (4) (4) A vertical cavity (6) is formed in the face shell (4), and the cavity (6) is filled with a heat insulating material (7) such as expanded polystyrene resin. When arranged in a tear joint shape, both ends in the left-right direction of the wall inevitably have an uneven shape protruding by half a block for each step, but in this way, both ends of the panel are cut linearly. Without making it, the left and right ends are torn and left as they are.
(8) (8) ... is a steel rod for binding, which penetrates each block (2) (2) ... Arranged as described above and is inserted in the same direction as the torn joint (9). Shows. As for these steel rods (8), a plurality of blocks (2) and (2) are respectively inserted at required positions in the left-right direction. (10) (10)
Is a transverse bar arranged in a direction perpendicular to the steel rod (8).

In FIG. 2, (11) is called a head joint, and is a pair of angle-shaped girder members (12) (1) arranged in parallel.
2) and a connecting rod (13) fixed between the two girder members (12) (12) in order to hold the girder members (12) (12) at a predetermined interval position. Along with
At the ends of both girder members (12) (12), the same girder member (12)

Next, the nut (22) of the suspension fitting (21) is screwed and attached to the end of the steel rod (8) on the upper end side of the wall, and as shown in FIG. ), Suspend the hanging wire (26) such as a crane, and erect it vertically, and then install it at the specified wall position as shown in FIG. As shown in FIG. 1, the block laminated panel (20) is formed between the respective panels (20) (20) because both left and right ends of the block laminated panel (20) are not flush with each other as tear joints. , A space portion (23) (23) for one block is generated for each stage (hatched portion in the figure). Therefore, as shown in FIG. 5, the reinforcement bar (24) is inserted from the space (23), or the horizontal bar (20) of each panel (20) (20) is pulled out and connected to each other. Another block (25) of the same shape prepared is connected and inserted into the space (23) from the side and filled. After that, concrete is cast from above to construct an integral formwork concrete block wall. The same construction method can be applied to the corner portion as well.

EFFECTS OF THE INVENTION As described above, in the present invention, since each panel has a tear joint shape, it is possible to insert the steel rod for binding in the required positions in the left-right direction and to fasten the block in one direction to form an integrated block laminate. You can make panels. Therefore, the number of parts and the number of working steps can be reduced as compared with the conventional ones, and the stress can be easily managed because only the compressive force in one direction is managed. Further, in the present invention, in such a broken joint-shaped block laminated panel, since both ends in the wall direction are not the same as the broken joints, there is a space when each panel is arranged in the wall direction. In this space, the connecting work of the horizontal streaks of each panel can be performed, the connecting work is easy, and there is no need to separate the panels and pour the concrete pillar. In addition, since continuous tear joints are formed between the respective panels, the pattern of the tear joints is not interrupted and the appearance is good as compared with the case where the edges are joint joints.
