Description

  The present invention relates to a stacked structure of concrete blocks and a concrete block used for the same.

  Conventionally, when building construction such as a concrete block is to be performed, for example, the process shown in FIG. 5 has been performed. That is, first, after preparing concrete blocks to be stacked (S1), a vertical method (S2) in which yarns are stretched and paralleled while confirming the horizontality and directionality of the concrete blocks is performed. A mortar is applied to the ground (upper corner portion of the concrete) (S3), and the vertical joint mortar is applied to the ridge corner portion of the concrete block to be stacked next on the parallel concrete block (S4) and stacked (S5). Thereafter, in order to maintain the appearance between the adjacent concrete blocks by filling mortar (S6) in the void portion of the adjacent concrete block and the hollow portion of the concrete block, placing the horizontal stripes at a predetermined position (S7), The excess mortar that protrudes is scraped off with a scissors or the like, and the mortar joint is finished (S8, S9) so as not to protrude from the surface. By repeating such a series of operations, the construction work of concrete blocks is carried out.

  The built-up concrete block is required to have a design. Therefore, for example, Patent Document 1 discloses a concrete block that secures design by forming a design straight line 3 to increase the bonding area of the connecting mortar and not providing joint cost on the side surface 5.

Japanese Utility Model Publication No. 52-074611

  However, since the concrete block described in Patent Document 1 is provided with design straight lines on both side surfaces, the production cost increases, and the design straight lines 3 are not aligned after assembly due to dimensional tolerance for each product. there were.

  In addition, in the conventional method, it is a very skillful task to stack concrete blocks while maintaining level, horizontality and direction while paying attention to the amount of mortar between adjacent concrete blocks vertically and horizontally. Yes, it was extremely difficult for unskilled workers to build concrete blocks neatly. Furthermore, mortar noro (that is, the mortar portion of the mortar) oozes out between the adjacent concrete blocks and often contaminates the concrete block wall surface, and it takes time to remove the dirt.

  Such difficulty and complexity of the concrete block assembling work has contributed to an increase in construction costs, and further improvement has been desired.

  This invention is made | formed in view of the above subjects, and it aims at providing the concrete block which can perform the masonry construction with high designability, without requiring skill.

  For this reason, the present invention is characterized in that, in a concrete block having recesses for inserting vertical bars on both ends, a pseudo joint is formed on the outer edge of the recess on at least one end side.

  Moreover, the said recessed part is formed so that the space in a recessed part may reduce toward the exit side from the entrance side into which a vertical streak is inserted.

The present invention has the following excellent effects.
(1) Even an unskilled worker in a building work can lay up concrete blocks easily and aesthetically.
(2) Since the pseudo joint is provided on at least one end side, the vertical joint construction can be omitted. As a result, the construction cost can be reduced.
(3) Since the inner space of the recess is reduced from the inlet side where the vertical stripe is inserted toward the outlet side, that is, in the direction in which the mortar is inserted, the inner space of the recess is formed in a cylindrical space having the same diameter. Compared to the case, the amount of mortar for bonding can be reduced.

It is a perspective view showing an embodiment concerning a concrete block of the present invention. 1A is a plan view, and FIG. 1B is a cross section taken along the line AA. It is a perspective view which shows a mode that the concrete block of FIG. 1 was assembled. It is a flowchart explaining the work process in the construction work of the concrete block of this invention. It is a flowchart explaining the work process in the assembly work of the conventional concrete block.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. The concrete blocks described in the present invention include hollow concrete blocks, decorative concrete blocks, and formwork concrete blocks.

The concrete block of the present invention has a structural feature that a pseudo joint is provided on at least one end side, so that the vertical joint construction can be omitted. That is, the concrete block 1 of the present invention is formed by pouring mortar into a mold (not shown) and forming a substantially rectangular parallelepiped shape, and has a rectangular exterior surface 11, and FIGS. 1 and 2. As shown in FIG. 2, longitudinal bars or the like (not shown) are inserted, and semicircular recesses 2 filled with concrete, mortar, or the like are formed at both ends. Moreover, the joint 3 is formed inside the recessed part 2, and the recessed part 2 between the adjacent concrete blocks 1 can be reliably filled with the mortar with which the recessed part 2 is filled. In this specification, a side surface refers to the surface where the recessed part 2 was provided in FIG. 1 among the surfaces where the concrete blocks piled up contact.

  On only one side of the concrete block 1, a pseudo joint 4 is formed on the outer surface side edge of the recess 2, and a meat portion 5 that abuts on the adjacent concrete block 1 is provided.

  As shown in FIG. 2B, the concave portion 2 includes a first inclined portion 21 and a second inclined portion that are slightly inclined outward in the direction in which the vertical stripe is inserted (from the top to the bottom in the figure). A two-stage slope composed of 22 is formed, and by narrowing the space between adjacent concrete blocks 1 in the direction in which the vertical bars are inserted, the mortar can be firmly packed in the space.

  As shown in FIG. 3, the concrete block 1 configured as described above is stacked in the vertical direction and the horizontal direction. Moreover, although the construction procedure is shown in FIG. 4, in order to compare with FIG. 5 which is a prior art example, about the same procedure, the same code | symbol is attached | subjected and a construction procedure is demonstrated.

  As shown in FIG. 4, the concrete block 1 of the present invention is a vertical method in which the concrete blocks 1 to be stacked (S1) are prepared (S1), and then the yarns are stretched in parallel while confirming the horizontality and directionality of the concrete blocks ( S2) is performed, and mortar (mortar 8 shown in FIG. 3) is applied to the horizontal joints (upper corner portions of the concrete) of the concrete blocks already arranged in parallel (S3) and stacked (S5). After that, mortar is filled in the gaps between adjacent concrete blocks and the hollow parts of concrete blocks (S6), horizontal stripes are placed at predetermined positions (S7), and the gaps between adjacent concrete blocks are filled with scissors or the like. The finished mortar joint is finished (S8), and excess mortar is removed and stacked. Further, the placement joint 3 can improve the lateral connectivity between the concrete blocks 1, can prevent rainwater from penetrating from the outer surface, and can prevent the filling mortar from being neutralized.

  Therefore, in the concrete block of the present invention, since the artificial joint 4 having high design properties is formed in advance, the application of the vertical joint mortar (S4) and the vertical joint finishing (S9) are unnecessary as compared with the conventional example. In addition, as shown in FIG. 3, vertical joints are naturally formed after assembly.

  The gist of the present invention is that a pseudo joint is provided at one end of the concrete block, and can be freely changed without departing from the gist of the present invention. Therefore, for example, the cavity 11 shown in FIG. 2 may not be provided, or the illustrated bottomed shape may be changed to a bottomless shape. For example, in order to further improve the design, a pattern may be applied to the exterior surface.
