Description

[Technical field]

[0001] The present invention relates to a method for forming a wall material by laying and stacking strips of a clay-like hardenable material to form a wall material. [Background technology]

[0002] For example, Patent Document 1 discloses a method of constructing a wall material by laying and stacking strips of a clay-like hardening material. By using mortar as the hardening material, such a wall material can be used as a formwork when pouring a cement composition such as concrete. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-157336 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, lateral pressure is applied to the formwork due to the poured cement composition. In the method of Patent Document 1, in order to ensure that the formwork has sufficient strength to resist the lateral pressure, it is necessary to increase the thickness or reinforce it with metal fittings. Note that such strength problems are not limited to the wall material used for the formwork. [Means for solving the problem]

[0005] A wall material forming method that solves the above problem forms a wall material by laying and stacking clay-like strips. The wall material has a left wall portion, a right wall portion, and a vertical rib portion formed between the left wall portion and the right wall portion. The wall material forming method includes a left wall portion forming step of forming the left wall portion, a vertical rib portion forming step of connecting the left wall portion to the vertical rib portion, and a right wall portion forming step of connecting the vertical rib portion to the right wall portion.

[0006] According to the above-mentioned configuration, the strength of the wall material can be increased by the vertical rib portion. In the above configuration, the left wall forming step includes a left wall right-advancing strip laying step of advancing the strip to the right from the left end of the left wall. The vertical rib forming step includes a vertical rib joint forward bending step of bending the laying direction of the strip from the right to the front direction at the joint of the left wall and the vertical rib, a vertical rib forward strip laying step of advancing the strip from the joint of the left wall and the vertical rib, a vertical rib front end folding step of folding back the laying direction of the strip from the front direction to the rear direction at the front end of the vertical rib, and a vertical rib backward strip laying step of advancing the strip backward from the front end of the vertical rib. The right wall formation process includes a vertical rib portion junction right bending step, in which the laying direction of the strip material is bent from the rear direction to the right direction at the junction of the right wall portion and the vertical rib portion, and a right wall portion right-advancing strip material laying step, in which the strip material is advanced to the right from the junction of the right wall portion and the vertical rib portion to the right end portion of the right wall portion.

[0007] According to the above-mentioned configuration, the steps of the left wall portion forming process, the vertical rib portion forming process, and the right wall portion forming process are performed successively, so that the time required for forming the wall material can be shortened. In the above configuration, the left wall forming step includes a left wall left-advancing strip laying step of advancing the strip to the left behind the vertical rib. The right wall forming step includes a right wall right end folding step of folding back the strip at the right end of the right wall to the rear side of the vertical rib, and a right wall left-advancing strip laying step of advancing the strip to the left behind the vertical rib. The left wall left-advancing strip laying step is performed immediately after the right wall left-advancing strip laying step.

[0008] According to the above-mentioned configuration, the step of laying the strip material on the right wall left and the step of laying the strip material on the left wall left are performed successively, so that the forming time can be shortened. Also, since the left wall and the right wall are formed by the strip material moving to the right and left, the degree of freedom in the thickness of the left wall and the right wall can be increased.

[0009] The wall material forming method for solving the above problem forms a wall material by laying and stacking clay-like strips in the left-right direction. The wall material has a lower wall portion, an upper wall portion, and a transverse rib portion formed between the lower wall portion and the upper wall portion and embedded in the cement composition. The wall material forming method includes a lower wall portion forming step of forming the lower wall portion, a transverse rib portion forming step of connecting the lower wall portion to form the transverse rib portion, and an upper wall portion forming step of connecting the transverse rib portion to form the upper wall portion.

[0010] According to the above-mentioned configuration, the strength of the wall material can be increased by the horizontal rib portion. In the above configuration, the transverse rib portion forming process includes a transverse rib portion right-advancing strip laying step in which the strip is advanced to the right while a protrusion portion at least a portion of which is located forward of the lower wall portion is formed, a transverse rib portion right end folding step in which the strip material is folded back to the rear at the right end of the transverse rib portion, and a transverse rib portion left-advancing strip laying step in which the strip material is advanced to the left behind the protrusion, and in the transverse rib portion left-advancing strip laying step, the strip material is laid so that it is flush with the rear surface of the lower wall portion.

[0011] According to the above configuration, the strip material is laid in the horizontal rib left-moving strip laying step so as to be flush with the rear surface of the lower wall portion, thereby shortening the time required to form the wall material. The wall material forming method for solving the above problem forms a wall material by laying and stacking clay-like strips. The wall material has a wall body, and vertical rib portions and horizontal rib portions that are integrally formed with the wall body and embedded in the cement composition. The wall material forming method includes a wall body forming step of forming the wall body, a vertical rib portion forming step of connecting the wall body to form the vertical rib portions, and a horizontal rib portion forming step of connecting the wall body to form the horizontal rib portions, and the vertical rib portion forming step is performed during the horizontal rib portion forming step to form an intersection between the vertical rib portion and the horizontal rib portion.

[0012] According to the above-mentioned configuration, by carrying out the vertical rib portion forming step during the horizontal rib portion forming step, it is possible to form the intersecting portions of the vertical rib portions and the horizontal rib portions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An embodiment of a method for forming a wall material will be described with reference to FIGS. As shown in Fig. 1, the wall material 10 is used as an embedded formwork when forming a structure by pouring a cement composition such as concrete. The 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.

[0015] The wall material 10 has a wall body 11, a vertical rib portion 12, and a horizontal rib portion 13. The wall body 11 is a portion formed according to the outer shape of the structure. The cement composition is poured inside the wall body 11. The vertical rib portion 12 and the horizontal rib portion 13 are connected to the wall body 11 by being integrally formed with the wall body 11. The vertical rib portion 12 and the horizontal rib portion 13 are embedded in the poured cement composition by protruding to the inside of the wall body 11. The vertical rib portion 12 extends in the vertical direction inside the wall body 11. The horizontal rib portion 13 extends in the horizontal direction inside the wall body 11. In the following, the direction toward the inside of the wall body 11 in the horizontal direction is defined as the forward direction, and the direction opposite to the forward direction is defined as the rearward direction, and the left direction and the right direction are defined based on the wall body 11 viewed from the inside.

[0016] 2(a), in the wall material 10, a portion where the vertical rib portion 12 is formed on the wall main body 11 is referred to as the vertical ribbed wall portion 15. In the vertical ribbed wall portion 15, the vertical rib portion 12 is formed between a left wall portion 16 located on the left side of the vertical rib portion 12 and a right wall portion 17 located on the right side of the vertical rib portion 12. The left wall portion 16 and the right wall portion 17 are part of the wall main body 11.

[0017] 2(b), in the wall material 10, a portion where the horizontal rib portion 13 is formed on the wall main body 11 is referred to as a horizontal ribbed wall portion 20. In the horizontal ribbed wall portion 20, the horizontal rib portion 13 is formed between a lower wall portion 21 located below the horizontal rib portion 13 and an upper wall portion 22 located above the horizontal rib portion 13. The lower wall portion 21 and the upper wall portion 22 are part of the wall main body 11.

[0018] (Method of forming a wall with vertical ribs) A method for forming a vertically ribbed wall portion 15 will be described with reference to Figures 3 and 4. Here, the method for forming a vertically ribbed wall portion 15 having one vertical rib portion 12 will be described as an example. In Figures 3 and 4, the downward direction in the figure is the front direction, and the upward direction is the rear direction.

[0019] The method for forming a wall having vertical ribs includes a left wall forming step, a vertical rib forming step, and a right wall forming step. The left wall forming step and the right wall forming step are part of a wall main body forming step.

[0020] The left wall forming process includes a left wall right-moving strip laying step (S11) and a left wall left-moving strip laying step (S12). The vertical rib forming process includes a step of bending the vertical rib joint forward (S21), a step of laying a forward strip for the vertical rib (S22), a step of folding back the front end of the vertical rib (S23), and a step of laying a backward strip for the vertical rib (S24).

[0021] The right wall forming process includes a step of bending the vertical rib joint to the right (S31), a step of laying a strip material moving rightward on the right wall (S32), a step of folding back the right end of the right wall (S33), and a step of laying a strip material moving leftward on the right wall (S34).

[0022] 3(a), in the method for forming a wall with vertical ribs, first, a step of laying a strip material on the left wall portion to the right (S11) is performed. In the step of laying a strip material on the left wall portion to the right, the strip material is advanced from the left end of the left wall portion 16 to the joint between the left wall portion 16 and the vertical rib portion 12.

[0023] As shown in Figure 3 (b), when the strip reaches the joint between the left wall 16 and the vertical rib 12, a vertical rib joint forward bending step (S21) is performed. In the vertical rib joint forward bending step, the laying direction of the strip is bent from the right to the front, as shown by arrow 41. Next, the vertical rib forward strip laying step (S22) is performed. In the vertical rib forward strip laying step, the strip is advanced from the joint between the left wall 16 and the vertical rib 12 to the front end of the vertical rib 12, as shown by arrow 42.

[0024] As shown in Figure 3 (c), when the strip reaches the front end of the vertical rib portion 12, a vertical rib portion front end folding back step (S23) is performed. In the vertical rib portion front end folding back step, the laying direction of the strip is folded back from the front direction to the rear direction at the front end of the vertical rib portion 12 as shown by arrow 43. Next, a vertical rib portion backward strip laying step (S24) is performed. In the vertical rib portion backward strip laying step, the strip is moved backward from the front end of the vertical rib portion 12 to the joint between the right wall portion 17 and the vertical rib portion 12 as shown by arrow 44.

[0025] As shown in Fig. 3(d), when the strip reaches the joint between the right wall portion 17 and the vertical rib portion 12, a step of bending right at the vertical rib portion joint (S31) is performed. In the step of bending right at the vertical rib portion joint, the laying direction of the strip is bent from the rear to the right at the joint between the right wall portion 17 and the vertical rib portion 12, as shown by arrow 45. Next, a right wall right-advancing strip laying step (S32) is performed. In the right wall right-advancing strip laying step, the strip is advanced rightward from the joint between the right wall portion 17 and the vertical rib portion 12 to the right end of the right wall portion 17, as shown by arrow 46.

[0026] Next, as shown in Fig. 3(e), when the strip reaches the right end of the right wall portion 17, a right wall right end folding back step (S33) is performed. In the right wall right end folding back step (S33), the laying direction of the strip is folded back to the left at the right end of the right wall portion 17 as indicated by arrow 47. Next, a right wall left-advancing strip laying step (S34) is performed. In the right wall left-advancing strip laying step, the strip is advanced left from the right end of the right wall portion 17 behind the vertical rib portion 12 as indicated by arrow 48.

[0027] Next, as shown in FIG. 3(f), a left wall left-advancing strip laying step (S12) is performed. This is performed consecutively to a right wall left-advancing strip laying step (S34). In the left wall left-advancing strip laying step (S12), the strip is advanced leftward behind the vertical rib portion 12 to the left end of the left wall portion 16. When the strip reaches the left end of the left wall portion 16, the first layer of the vertically ribbed wall portion 15 having one vertical rib portion 12 is formed. Thereafter, these steps are repeated to stack the strips to form the vertically ribbed wall portion 15.

[0028] In addition, when forming a vertically ribbed wall portion 15 having a plurality of vertical rib portions 12, various processes are performed to form the wall portions between adjacent vertical rib portions 12 into a right wall portion 17 for the vertical rib portion 12 located on the left side and a left wall portion 16 for the vertical rib portion 12 located on the right side.

[0029] Specifically, as shown in Figure 4, using the vertical rib portion 12a as a reference, a step of laying a strip to the right on the left wall portion (S11), a step of bending forward at the vertical rib portion joint (S21), a step of laying a strip to the forward direction on the vertical rib portion (S22), a step of folding back the front end portion of the vertical rib portion (S23), a step of laying a strip to the backward direction on the vertical rib portion (S24), and a step of bending to the right at the vertical rib portion joint (S31) are performed.

[0030] Next, a left wall right-advancing strip laying step (S11) is performed with the vertical rib portion 12b as a reference. This left wall right-advancing strip laying step (S11) is also a right wall right-advancing strip laying step (S32) with the vertical rib portion 12a as a reference. Then, with the vertical rib portion 12b as a reference, a vertical rib joint forward bending step (S21), a vertical rib forward strip laying step (S22), a vertical rib front end folding back step (S23), a vertical rib backward strip laying step (S24), and a vertical rib joint right bending step (S31) are performed.

[0031] When these steps are completed up to the vertical rib portion 12n, a right wall portion right end folding back step (S33) is performed based on the vertical rib portion 12n. Then, a right wall portion left-advancing strip material laying step (S34) is followed by a left wall portion left-advancing strip material laying step (S12) to form a first layer of the vertically ribbed wall portion 15 having a plurality of vertical ribs 12. Thereafter, these steps are repeated to stack the strip materials, thereby forming the vertically ribbed wall portion 15 having a plurality of vertical ribs 12.

[0032] (Wall formation method with horizontal ribs) A method for forming a wall with horizontal ribs will be described with reference to Figures 5 to 9. The method for forming a wall with horizontal ribs includes a lower wall portion forming step, a horizontal rib portion forming step, and an upper wall portion forming step. The lower wall portion forming step and the upper wall portion forming step are part of a wall main body forming step.

[0033] The lower wall forming process includes a lower wall right-hand strip laying step (S41), a lower wall right end folding back step (S42), and a lower wall left-hand strip laying step (S43). As shown in FIG. 5, in the lower wall right-advancing strip laying step (S41), the strip is advanced rightward, as indicated by arrow 51, from the left end to the right end of the lower wall 21.

[0034] In the lower wall right end folding back step (S42), the right end of the lower wall 21 is folded back to the left as indicated by arrow 52. In the lower wall left-advancing strip laying step (S43), the strip is advanced leftward from the right end to the left end of the lower wall 21 as indicated by arrow 53. When the strip reaches the left end, the first layer of the lower wall 21 is formed. Thereafter, the steps from S41 to S43 are repeated to stack the strips, thereby forming the lower wall 21.

[0035] The transverse rib forming process includes a step of laying a right-hand strip material for the transverse rib (S51), a step of folding back the right end of the transverse rib (S52), and a step of laying a left-hand strip material for the transverse rib (S53). As shown in Figures 6(a) and 6(b), in the step (S51) of laying the strip material to the right of the horizontal rib portion, the strip material is advanced to the right so that a protrusion 55 is formed from the left end to the right end of the lower wall portion 21, with its front end located forward of the lower wall portion 21.

[0036] As shown in Figures 7(a) and 7(b), in a horizontal rib right end folding back step (S52), the laying direction of the strip is folded back to the left at the right end of the lower wall 21, as indicated by arrow 52. In a horizontal rib leftward laying strip step (S53), the strip is advanced leftward, as indicated by arrow 53, from the right end to the left end of the lower wall 21 behind the protrusion 55. At this time, the amount of strip laid is increased or the laying speed of the strip is slowed down so that the strip is flush with the rear surface of the lower wall 21. When the strip is laid up to the left end of the lower wall 21, the first layer of the horizontal rib 13 is formed.

[0037] Thereafter, as shown in FIG. 8, in a right-moving strip laying step (S51) for each layer of the transverse rib portion, the strip material is laid and stacked while adjusting the amount of protrusion from the lower wall portion 21 according to the shape of the transverse rib portion 13, thereby forming the transverse rib portion 13.

[0038] The upper wall portion forming process includes an upper wall portion right-hand-moving strip laying step (S61), an upper wall portion right end folding back step (S62), and an upper wall portion left-hand-moving strip laying step (S63). The upper wall right-advancing strip laying step (S61) is the same as the lower wall right-advancing strip laying step (S41). The upper wall right end folding back step (S62) is the same as the lower wall right end folding back step (S42). The upper wall left-advancing strip laying step (S63) is the same as the lower wall left-advancing strip laying step (S43).

[0039] 9, the upper wall portion right-hand strip laying step (S61), the upper wall portion right end folding back step (S62), and the upper wall portion left-hand strip laying step (S63) are repeated to stack the strips, thereby forming the upper wall portion 22. In this way, the wall portion 20 with horizontal ribs is formed.

[0040] (Method of forming the intersection of the vertical rib portion and the horizontal rib portion) As shown in FIG. 10, at the intersection of the vertical rib portion 12 and the horizontal rib portion 13, the vertical rib portion forming process is carried out during the horizontal rib portion right-ward strip laying step (S51) of the horizontal rib portion forming process, as indicated by the arrow.

[0041] (action) The wall material 10 shown in FIG. 1 is formed by repeating the above-mentioned method for forming a wall with vertical ribs and the method for forming a wall with horizontal ribs.

[0042] The effects of this embodiment will be described. (1) The wall material 10 has the vertical ribbed wall portion 15, which increases its strength. This allows the thickness of the wall body 11 to be reduced, and the amount of reinforcement using metal fittings to be minimized.

[0043] (2) In addition, the vertical rib portion 12 forms an uneven surface on the inside, so that the cement composition and the formwork can be integrated together. This allows the wall material 10 to be regarded as a structural body.

[0044] (3) The steps of the left wall portion forming process, the vertical rib portion forming process, and the right wall portion forming process are performed consecutively, thereby shortening the time required to form the wall material 10. (4) The left wall left-advance strip laying step is performed immediately after the right wall left-advance strip laying step. This shortens the time required to form the wall material 10. In addition, the left wall portion 16 and the right wall portion 17 are formed by the right and left advancement of the strip material, which increases the degree of freedom in the thickness of the left wall portion 16 and the right wall portion 17.

[0045] (5) The wall material 10 has the horizontal ribbed wall portion 20, which increases the strength of the wall material 10. This allows the thickness of the wall body 11 to be reduced and the amount of reinforcement using metal fittings to be minimized.

[0046] (6) In addition, the horizontal rib portion 13 forms an uneven surface on the inside, so that the cement composition and the formwork can be integrated together. This allows the wall material 10 to be regarded as a structural body.

[0047] (7) In the horizontal rib leftward strip laying step (S53), the strip is laid so as to be flush with the rear surface of the lower wall portion 21, so that the time required to form the wall material 10 can be shortened. 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.

[0048] In the above embodiment, the left and right directions are defined based on the view of the wall main body 11 from the inside. However, the left and right directions may be defined based on the view of the wall main body 11 from the outside.

[0049] In the above embodiment, the wall material 10 has a wall main body 11, a vertical rib portion 12, and a horizontal rib portion 13. However, the wall material 10 may be composed of the wall main body 11 and the vertical rib portion 12, or may be composed of the wall main body 11 and the horizontal rib portion 13.

[0050] In the above embodiment, the wall material 10 is used for an embedded formwork. However, the wall material 10 may be used for a wall of a building or the like. [Explanation of symbols]
