DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An embodiment of a method for forming a peripheral wall material will be described with reference to FIGS. (Structure of perimeter wall materials) As shown in Fig. 1(a) and Fig. 1(b), the peripheral wall material 10 is formed in a cylindrical wall shape. The peripheral wall material 10 is used as an embedded formwork when a cement composition such as concrete is poured to form a structure, or as a wall of a shaped object such as a building. The cement composition formed to match the outer shape of the structure is poured inside the peripheral wall material 10. The peripheral wall material 10 is formed by laying and stacking clay-like strips using a three-dimensional (3D) printer. The clay-like strips are, for example, mortar (cement-based material) that has hardening properties.

[0014] The peripheral wall material 10 has an opening 11. Fig. 1(a) shows the peripheral wall material 10 as viewed from the outside front of the opening 11. An embedded member such as a sleeve is placed in the opening 11 before the cement composition is poured. In the following, up, down, left and right are defined based on the state in which the opening 11 is viewed from the outside front as shown in Fig. 1(a).

[0015] As shown in FIG. 1(a), the peripheral wall material 10 has a lower wall portion 12, an upper wall portion 13, a left wall portion 14, and a right wall portion 15. In FIG. 1(a), the portions corresponding to the left wall portion 14 and the right wall portion 15 are indicated by thick dots. The lower wall portion 12 is a wall portion located on the lower side of the opening 11. The upper wall portion 13 is a wall portion located on the upper side of the opening 11. The left wall portion 14 is a wall portion located on the left side of the opening 11. The right wall portion 15 is a wall portion located on the right side of the opening 11. The opening 11 of the peripheral wall material 10 is formed by laying and stacking strip materials so as to form the lower wall portion 12, the upper wall portion 13, the left wall portion 14, and the right wall portion 15. In addition, as shown in FIG. 1(b), the peripheral wall material 10 has a back wall portion 16. The back wall portion 16 is a wall portion that connects the left wall portion 14 and the right wall portion 15 on the back side of the opening 11.

[0016] (Peripheral wall material formation method) A method for forming the peripheral wall material 10 will be described with reference to Figs. 2 to 5. The peripheral wall material forming method includes a lower wall portion forming step, a left wall portion forming step, a rear wall portion forming step, a right wall portion forming step, and an upper wall portion forming step.

[0017] In the lower wall portion forming step, the lower wall portion 12 is formed by stacking layers formed by winding a strip material around the circumference. The left wall forming process includes a left wall right-moving strip laying step (S11), an opening left edge folding back step (S12), and a left wall left-moving strip laying step (S13).

[0018] The rear wall forming process includes a rear wall clockwise strip laying step (S21) and a rear wall counterclockwise strip laying step (S22). The right wall forming process includes a step of laying a leftward-moving strip material on the right wall (S31), a step of folding back the right edge of the opening (S32), and a step of laying a rightward-moving strip material on the right wall (S33).

[0019] As shown in FIG. 2, in the left wall right-advancing strip laying step (S11), the strip is advanced rightward from the left end of the left wall 14 to the left edge of the opening 11 as indicated by the arrow 51. The left edge of the opening 11 is a position that corresponds to the width of the opening 11 in the left-right direction in the layer to be laid. When the strip reaches the left edge of the opening 11, the opening left edge folding back step (S12) is performed. In the opening left edge folding back step, the laying direction of the strip is folded back from the right to the left at the left edge of the opening 11 as indicated by the arrow 52. Next, the left wall left-advancing strip laying step (S13) is performed. In the left wall left-advancing strip laying step, the strip is advanced leftward from the left edge of the opening 11 to the left end of the left wall 14 as indicated by the arrow 53.

[0020] 3, when the strip material is laid up to the left end of the left wall 14, a rear wall clockwise strip material laying step (S21) is performed continuously. In the rear wall clockwise strip material laying step, the strip material is laid clockwise on the rear wall 16, specifically from the left end of the left wall 14 to the right end of the right wall 15, as indicated by arrow 54.

[0021] As shown in FIG. 4, when the strip material is laid up to the right end of the right wall 15, a right wall left-advance strip laying step (S31) is performed successively. In the right wall left-advance strip laying step, the strip material is advanced leftward from the right end of the right wall 15 to the right edge of the opening 11 as indicated by an arrow 55. The right edge of the opening 11 is a position according to the width of the opening 11 in the left-right direction in the layer to be laid. When the strip material is laid up to the right edge of the opening 11, a right edge folding back step (S32) is performed. In the right edge folding back step, the laying direction of the strip material is folded back from the left to the right at the right edge of the opening 11 as indicated by an arrow 56. Next, a right wall right-advance strip laying step (S33) is performed. In the right wall right-advance strip laying step, the strip material is advanced rightward from the right edge of the opening 11 to the right end of the right wall 15 as indicated by an arrow 57.

[0022] As shown in Fig. 5, when the strip advances to the right to the right end of the right wall 15, a rear wall counterclockwise strip laying step (S22) is performed consecutively. In the rear wall counterclockwise strip laying step, the strip is laid counterclockwise on the rear wall 16, specifically from the right end of the right wall 15 to the left end of the left wall 14, as indicated by arrow 58. Then, one layer is formed when the strip reaches the left end of the left wall 14. Thereafter, these steps are repeated to stack the strips, thereby forming a peripheral wall portion having the opening 11.

[0023] In the upper wall forming process, one layer is formed by winding the strip material so as to be laminated on the left wall 14, the back wall 16, and the right wall 15. Then, the upper wall 13 is formed by laminating the layer.

[0024] (action) After the lower wall portion forming step, the left wall portion forming step, the back wall portion forming step, and the right wall portion forming step are repeated to stack the strip materials, thereby forming a peripheral wall portion having an opening 11. Thereafter, the upper wall portion forming step is performed to form the peripheral wall material 10.

[0025] The effects of this embodiment will be described. (1) According to the above embodiment, the opening 11 can be formed in the peripheral wall material 10 by laying and stacking the strip materials.

[0026] (2) The left wall leftward strip laying step, the rear wall rightward strip laying step, and the right wall leftward strip laying step are performed successively. This shortens the time required to form the peripheral wall material 10, and also enables the left wall 14, the rear wall 16, and the right wall 15 to be seamlessly connected.

[0027] (3) The right wall right-turning strip laying step, the back wall left-turning strip laying step, and the left wall right-turning strip laying step are performed successively. In addition to the effect described in (2), this provides an increased degree of freedom in terms of the thickness of each wall 14-16, since the walls 14-16 are formed by the rightward and leftward movement of the strip.

[0028] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. The peripheral wall material may have a plurality of openings 11 arranged in the horizontal direction.

[0029] For example, as shown in FIG. 6(a), the peripheral wall material 60 may have a left opening 61 and a right opening 62. The peripheral wall material 60 has a left wall portion 14 on the left side of the left opening 61, a right wall portion 15 on the right side of the right opening 62, and a central wall portion 63 between the left opening 61 and the right opening 62. In FIG. 6(a), the central wall portion 63 is indicated by dots darker than the left wall portion 14 and the right wall portion 15. In this configuration, the peripheral wall material forming method further includes a central wall portion forming step before or after the left wall portion forming step, the back wall portion forming step, and the right wall portion forming step. The central wall portion forming step includes a central wall portion rightward strip laying step (S41), a central wall portion laying direction turning back step (S42), and a central wall portion leftward strip laying step (S43).

[0030] As shown in FIG. 6(b), in the central wall right-advancing strip laying step (S41), the strip is advanced rightward from the left end of the central wall 63 to the right end of the central wall 63 as indicated by an arrow 65. When the strip reaches the right end of the central wall 63, a central wall laying direction reversal step (S42) is performed. In the central wall laying direction reversal step, the laying direction of the strip is reversed from the right to the left at the right end of the central wall 63 as indicated by an arrow 66. Next, a central wall left-advancing strip laying step (S43) is performed. In the central wall left-advancing strip laying step, the strip is advanced leftward from the right end to the left end of the central wall 63 as indicated by an arrow 67. When the strip reaches the left end of the central wall 63, one layer that constitutes the central wall 63 is formed. Thereafter, the left wall forming process, the rear wall forming process, the right wall forming process, and the central wall forming process are repeated to stack the strips, thereby forming a peripheral wall portion having a left opening 61 and a right opening 62.

[0031] In addition, when there are three or more openings 11 in the horizontal direction, the opening located at the left end is referred to as the left opening, the opening located at the right end is referred to as the right opening, and each of the walls sandwiched between adjacent openings is referred to as the central wall, and various processes are performed accordingly.

[0032] In the above embodiment, the top, bottom, left and right are defined based on the view of the opening 11 from the front outside. However, the present invention is not limited to this, and the top, bottom, left and right may be defined based on the view of the opening 11 from the front inside. [Explanation of symbols]
