  The mode for carrying out the present invention will be described in more detail with reference to the drawings specifically illustrated as follows.

  An embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a rising block, and the configuration of the rising block 1 will be described below.

  The rising block 1 of the present embodiment is a concrete secondary product that is produced in advance using a mold in a concrete molding factory and then carried into a construction site, and is a hollow used for building a rising at a foundation portion of a building. This is a precast concrete (PC) block. The inner core reinforcing bars can be appropriately arranged according to the required strength.

  Opening portions 11 and 12 are provided on the top surface and the bottom surface, respectively, and side wall portions 13 and 13 are erected on both side surfaces, and a side opening is provided between at least one side wall portion 13 and 13. Part 14 is formed.

  The shape of the rising block 1 of the present embodiment is mainly from one character (FIG. 1), L-shape (FIG. 2), T-shape (FIG. 3), cross shape (FIG. 4), and one end character (FIG. 5). Depending on these shapes, the number of the side wall portions 13 is 2 to 4, or the shape is flat or bent.

  In addition, for example, when a curved shape rises due to the design of the building, it can be formed on the curved side wall portion 13 and can correspond to various rising shapes.

  Moreover, in this embodiment, the edge notch part 13a can also be provided in the edge of the side wall part 13 (refer FIGS. 1-5). Furthermore, in this embodiment, the lower edge notch part 13b can also be provided in the lower edge of the side wall part 13 (refer FIGS. 1-5).

  Furthermore, in this embodiment, the decorative groove part 13c can be formed in at least one part of the outer surface of the side wall part 13 of the rising block 1 (refer FIGS. 6-9), and the location which faces the outer side of a building is shown. Can be decorated. In this embodiment, it is formed in a vertical groove shape.

  Furthermore, in this embodiment, it is possible to form a joint protrusion 13d on the edge of the side wall 13 of the rising block 1 so that the joint protrusions 13d and 13d between the adjacent rising blocks 1 and 1 can be abutted. (Refer to FIG. 7). In particular, the appearance of the connecting portion on the outer surface when the decorative groove portion 13c is provided can be clearly seen.

  Furthermore, in the present embodiment, rack-like anchor irregularities 13e can be formed on the inner surface of the side wall portion 13 of the rising block 1 (see FIGS. 6 and 7), and the rising block 1 is filled. Fixation with concrete can be improved.

  Next, a method for constructing a rise in the basic part of the building in the present embodiment will be described.

  First, as shown in FIG. 10, rising rebars P, P... Are embedded in parallel on the upper surface of the flat mat foundation B and protrude upward. These rising rebars P are assembled according to a conventional method and are also connected in the horizontal direction.

  Then, as shown in FIG. 11, a plurality of rising blocks 1, 1... Are covered with the standing reinforcing bars P, P. I will continue to place it. In this embodiment, a single character shape is placed on the straight line portion, an L shape is formed on the corner portion, a cross shape is formed on the intersection portion, a T shape is formed on the branch portion, and a single character for the end portion is appropriately placed on the end portion. (See FIG. 12).

  In the present embodiment, an edge notch 13a is provided at the edge of the side wall 13 of the rising block 1, and the notch 13a / 13a between the adjacent rising blocks 1 and 1 is filled with concrete and cured. Thus, the cutout portions 13a and 13a of the rising blocks 1 and 1 can be coupled and integrated as a margin for both blocks. At this time, the rising blocks 1 and 1 are placed so as to be adjacent to each other so that a gap is not formed as much as possible, and a plate material or the like is appropriately filled so that the concrete does not flow out from the notches 13a and 13a. it can.

  Further, even when the edge of the side wall portion 13 of the rising block 1 is flat, it can be placed so that the rising blocks 1 and 1 are adjacent to each other so as not to create a gap as much as possible. As shown in FIG. 4, the gap can be formed by placing the substrate with a slight gap, and a wedge-shaped cotter C is disposed so as to straddle between the rising blocks 1 and 1, and Outflow can be prevented.

  Then, concrete is filled from the upper surface opening 11 of these rising blocks 1 and cured. Known methods can be employed for the concrete curing method.

  By doing so, the mat base B and the bottom opening 12 can be combined and integrated, and the side openings 14 and 14 of the adjacent rising blocks 1 and 1 can be combined and integrated.

  In this embodiment, the lower edge notch 13b is provided at the lower edge of the side wall 13 of the rising block 1, and the lower edge notch 13b of the adjacent rising block 1 is filled with concrete and hardened. The coupling area of the block 1 and the base portion B can be expanded, and the block 1 and the base portion B can be installed more stably.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of “Claims”. The shape of the bottom opening 12 and the side wall 13 can be changed according to the design of the building.

  In addition, the shape of the upper surface opening 11 can be increased to such an extent that the strength is not impaired, and the decorative groove 13c is not limited to the vertical groove, but can be provided with various patterns. Belongs to a range.
