Description

[Technical Field]

[0001] The present invention relates to a fixture for positioning column reinforcement. [Background technology]

[0002] The column reinforcement (column rebar) that is placed inside the cast-in-place concrete and protrudes from its top surface must be positioned accurately. This is especially important when installing precast concrete (PC) columns on top of it. Patent Documents 1 and 2 disclose a device (jig) for positioning column reinforcement. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-199952 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-171508 Summary of the Invention [Problem to be solved by the invention]

[0004] In high-rise buildings, the load that the columns must support on the lower floors is greater, so the columns are made thicker and have more column reinforcement.In contrast, the load that the columns must support on the higher floors is smaller, so the columns are made thinner and have fewer column reinforcement. In the technology described in Patent Document 1, the position of the column reinforcement is determined by the position of the holes in the template. Therefore, if the position of the column reinforcement differs depending on the floor, it is necessary to prepare a template according to the position of each column reinforcement, and the same template cannot be used on all floors. The technology described in Patent Document 2 can accommodate the positioning of column reinforcement bars according to the different thicknesses of columns on each floor, and the same jig can be used on all floors. However, since adjacent flat plates do not necessarily form a right angle, it is not possible to accurately align the column reinforcement bars. The present invention aims to solve, for example, such problems. [Means for solving the problem]

[0005] The column reinforcement fixing jig comprises a frame and a plurality of single clamps fixed to the outside of the frame. The frame has four or more frame members connected in a ring shape and corner members fixed to the frame members so that adjacent frame members form a predetermined angle. The frame members have a plurality of frame fixing holes through which frame fixing members for connecting adjacent frame members are inserted, corner fixing holes through which corner fixing members for fixing the corner members are inserted, and a plurality of clamp fixing holes through which clamp fixing members for fixing the single clamps are inserted. The frame member may have a first plate portion shaped like an elongated plate and a second plate portion shaped like an elongated plate. The first plate portion and the second plate portion may be connected to each other substantially perpendicularly in the width direction. The frame fixing hole may be provided in the first plate portion. The clamp fixing hole may be provided in the second plate portion. The frame member may have three or more frame fixing holes. The corner fixing holes may also serve as the frame fixing holes. The frame member may be made of steel. [Effects of the Invention]

[0006] According to the column reinforcement fixing jig, the angle formed by the adjacent frame members is set to a predetermined angle by the corner members, which prevents distortion of the frame portion and enables accurate alignment of the column reinforcement. If there are three or more frame fixing holes, the size of the frame can be changed, and the same column reinforcement fixing jig can be used for columns of different thicknesses.

[0008] The column reinforcement fixing jig 10 will be described with reference to FIGS. The column reinforcement fixing jig 10 is used to fix column reinforcement so that the position of the column reinforcement is as designed when manufacturing concrete members such as column-beam joints by casting in place. The column reinforcement fixing jig 10 has, for example, a frame portion 12 and single clamps 13a to 13z, 13α, and 13β. The frame portion 12 has, for example, four frame members 23a to 23d and four corner members 24a to 24d. The frame members 23a to 23d are joined together in a ring shape. Adjacent frame members 23a to 23d are fixed and joined together by frame fixing members 21a to 21d, such as bolts and nuts. The corner members 24a to 24d are fixed to the frame members 23a to 23d so that two adjacent frame members 23a to 23d form a right angle. The corner members 24a to 24d are fixed to the frame members 23a to 23d by corner fixing members 22a to 22h, such as bolts and nuts. The single clamps 13a-13z, 13α, and 13β are fixed to the outside of the frame 12 by clamp fixing members 14a-14z, 14α, and 14β, such as bolts and nuts. The single clamps 13a-13z, 13α, and 13β are used to fix the column reinforcement by clamping it. The inner diameter of the single clamps 13a-13z, 13α, and 13β is approximately the same as the diameter of the column reinforcement to be clamped, allowing the column reinforcement to be firmly clamped.

[0009] The corner member 24a will be described with reference to FIG. The corner members 24a to 24d have the same configuration, so the corner member 24a will be described here as an example. The corner member 24a is, for example, an L-shaped steel plate. The corner member 24a has, for example, a first corner plate portion 41, a second corner plate portion 42, and fixing holes 43a to 43c. The first corner plate portion 41 is a substantially rectangular plate. The second corner plate portion 42 is a substantially rectangular plate that is in the same plane as the first corner plate portion 41 and forms a substantially right angle with it. The fixing holes 43a to 43c penetrate the corner member 24a in the thickness direction. The fixing hole 43a is provided near the tip of the first square plate portion 41, and a frame fixing member 21a for fixing the square member 24a to the frame member 23d is inserted through the fixing hole 43a. The fixing holes 43b are provided at the joint between the first corner plate portion 41 and the second corner plate portion 42, and the corner fixing members 22a for fixing the frame members 23a and 23d are inserted through the fixing holes 43b. The fixing hole 43c is provided near the tip of the second corner plate portion 42, and a corner fixing member 22b for fixing the corner member 24a to the frame member 23a is inserted through the fixing hole 43c. Fixing holes 43a and 43c are provided at positions that form an exact right angle to fixing hole 43b, so that frame member 23a and frame member 23d are joined together so as to form an exact right angle.

[0010] The frame member 23a will be described with reference to FIGS. Since the frame members 23a and 23c have the same configuration, the frame member 23a will be described here as an example. The frame member 23a is, for example, an equal-leg angle steel member. The frame member 23a has, for example, a first plate portion 31a and a second plate portion 32a. The first plate portion 31a and the second plate portion 32a are each shaped like an elongated, approximately rectangular plate. The first plate portion 31a and the second plate portion 32a are adjacent to each other in the width direction and connected approximately perpendicular to each other.

[0011] The first plate portion 31a is provided with a plurality of frame fixing holes 33a to 33r aligned in a straight line in the longitudinal direction, and the frame fixing holes 33a to 33r penetrate the first plate portion 31a in the thickness direction. Frame fixing members 21d for fixing frame member 23a to frame member 23d are inserted through frame fixing holes 33a-33i. Frame fixing members 21a for fixing frame member 23a to frame member 23b are inserted through frame fixing holes 33j-33r. The reason there are multiple frame fixing holes 33a-33r on each side is to accommodate different column thicknesses. This allows the spacing between the column reinforcement fixed by single clamps 13f-13h attached to frame member 23b and the column reinforcement fixed by single clamps 13n-13p attached to frame member 23d to be different, so one column reinforcement fixing jig 10 can be used for work on floors with column thicknesses of different sizes. Corner fixing members 22b for fixing corner member 24a to frame member 23a are also inserted through frame fixing holes 33a-33i. Similarly, corner fixing members 22c for fixing corner member 24b to frame member 23a are also inserted through frame fixing holes 33j-33r. In other words, frame fixing holes 33a-33r also serve as corner fixing holes for inserting corner fixing members 22b, 22c. Because there are multiple frame fixing holes 33a-33r on each side, frame fixing holes 33a-33r other than those for inserting frame fixing members 21a, 21b can be used as corner fixing holes. 1, frame fixing member 21a is inserted through frame fixing hole 33a, and frame fixing member 21b is inserted through frame fixing hole 33r. Corner fixing member 22b is inserted through frame fixing hole 33e, and corner fixing member 22c is inserted through frame fixing hole 33n.

[0012] The second plate portion 32a has a plurality of clamp fixing holes 37a-37r aligned in a straight line in the longitudinal direction. The clamp fixing holes 37a-37r penetrate the second plate portion 32a in the thickness direction. That is, the direction in which the clamp fixing holes 37a-37r penetrate is approximately perpendicular to the direction in which the frame fixing holes 33a-33r penetrate. The fixing members 14a to 14h are inserted into the clamp fixing holes 37a to 37r to fix the single clamps 13a to 13h to the frame member 23a. The reason why the number of clamp fixing holes 37a-37r is greater than the number of single clamps 13a-13h to be fixed to the frame member 23a is to accommodate different column reinforcement arrangements. For example, the single clamp 13a for clamping column reinforcement located at a corner is fixed using one of the clamp fixing holes 37a-37f depending on the thickness of the column. Since the column reinforcement arrangement is known in advance from the design, if clamp fixing holes 37a-37r are provided to accommodate the arrangements on all floors, one column reinforcement fixing jig 10 can be used for work on all floors. For example, in the example of use shown in FIG. 1, clamp fixing member 14a is inserted into clamp fixing hole 37a, clamp fixing member 14b is inserted into clamp fixing hole 37g, clamp fixing member 14c is inserted into clamp fixing hole 37h, clamp fixing member 14d is inserted into clamp fixing hole 37i, clamp fixing member 14e is inserted into clamp fixing hole 37j, clamp fixing member 14f is inserted into clamp fixing hole 37k, clamp fixing member 14g is inserted into clamp fixing hole 37l, and clamp fixing member 14h is inserted into clamp fixing hole 37r.

[0013] The frame member 23b will be described with reference to FIGS. Like frame member 23a, frame member 23b is, for example, a steel angle, and has a first plate portion 31b and a second plate portion 32b. First plate portion 31b is provided with frame fixing holes 34a to 34q. Second plate portion 32b is provided with clamp fixing holes 38a to 38k. The overall length of frame member 23b is shorter than that of frame members 23a and 23c because single clamps 13h and 13o that clamp the column reinforcement bars at the corners are fixed to frame members 23a and 23c and do not need to be fixed to frame member 23b. Accordingly, the arrangement of the frame fixing holes 34a to 34q and the clamp fixing holes 38a to 38k also differs from that of the frame members 23a and 23c. However, in other respects, it is similar to the frame members 23a and 23c. 1, frame fixing member 21b is inserted through frame fixing hole 34a, frame fixing member 21c is inserted through frame fixing hole 34q, corner fixing member 22d is inserted through frame fixing hole 34e, and corner fixing member 22e is inserted through frame fixing hole 34n. Then, clamp fixing member 14i is inserted into clamp fixing hole 38b, clamp fixing member 14j is inserted into clamp fixing hole 38d, clamp fixing member 14k is inserted into clamp fixing hole 38f, clamp fixing member 14l is inserted into clamp fixing hole 38h, clamp fixing member 14m is inserted into clamp fixing hole 38j, and clamp fixing member 14n is inserted into clamp fixing hole 38k.

[0014] The frame member 23d will be described with reference to FIGS. Like the frame members 23a to 23c, the frame member 23d is, for example, a steel angle, and has a first plate portion 31d and a second plate portion 32d. The first plate portion 31d is provided with frame fixing holes 35a to 35q. The length of frame member 23d is approximately the same as that of frame member 23b, but the arrangement of frame fixing holes 35a to 35q and clamp fixing holes 39a to 39k is different from that of frame member 23b. 1, frame fixing member 21d is inserted through frame fixing hole 35a, and frame fixing member 21a is inserted through frame fixing hole 35q. Also, corner fixing member 22h is inserted through frame fixing hole 35d, and corner fixing member 22a is inserted through frame fixing hole 35m. Then, clamp fixing member 14w is inserted into clamp fixing hole 39a, clamp fixing member 14x is inserted into clamp fixing hole 39c, clamp fixing member 14y is inserted into clamp fixing hole 39e, clamp fixing member 14z is inserted into clamp fixing hole 39g, clamp fixing member 14α is inserted into clamp fixing hole 39i, and clamp fixing member 14β is inserted into clamp fixing hole 39k.

[0015] With reference to Figure 10, an example will be described in which the same column reinforcement fixing jig 10 is used for different column reinforcement arrangements. The layout in this example is for a higher floor than the example in Figure 1, and compared to the example in Figure 1, the columns are slightly thinner and there are fewer column reinforcement bars.

[0016] The frame fixing member 21a is inserted through the frame fixing hole 35q of the frame member 23d, the fixing hole 43b of the corner member 24a, and the frame fixing hole 33b of the frame member 23a. The corner fixing member 22a is inserted through the frame fixing hole 35m of the frame member 23d and the fixing hole 43a of the corner member 24a. The corner fixing member 22b is inserted through the fixing hole 43c of the corner member 24a and the frame fixing hole 33f of the frame member 23a.

[0017] The frame fixing member 21b is inserted through the frame fixing hole 34a of the frame member 23b, the fixing hole 43b of the corner member 24b, and the frame fixing hole 33q of the frame member 23a. The corner fixing member 22c is inserted through the fixing hole 43a of the corner member 24b and the frame fixing hole 33m of the frame member 23a. The corner fixing member 22d is inserted through the frame fixing hole 34e of the frame member 23b and the fixing hole 43c of the corner member 24b.

[0018] The frame fixing member 21c is inserted through the frame fixing hole 34p of the frame member 23b, the fixing hole 43b of the corner member 24c, and the frame fixing hole 33b of the frame member 23c. The corner fixing member 22e is inserted through the frame fixing hole 34l of the frame member 23b and the fixing hole 43b of the corner member 24c. The corner fixing member 22f is inserted through the fixing hole 43c of the corner member 24c and the frame fixing hole 33f of the frame member 23c.

[0019] The frame fixing member 21d is inserted through the frame fixing hole 35b of the frame member 23d, the fixing hole 43b of the corner member 24d, and the frame fixing hole 33q of the frame member 23c. The corner fixing member 22g is inserted through the fixing hole 43a of the corner member 24d and the frame fixing hole 33m of the frame member 23c. The corner fixing member 22h is inserted through the frame fixing hole 35f of the frame member 23d and the fixing hole 43c of the corner member 24d.

[0020] The clamp fixing member 14a is inserted into the clamp fixing hole 37b of the frame member 23a. The clamp fixing members 14b to 14f are inserted through the clamp fixing holes 37g to 37k of the frame member 23a, respectively, as in the example of FIG. The clamp fixing member 14h is inserted into the clamp fixing hole 37q of the frame member 23a.

[0021] The clamp fixing member 14i is inserted into the clamp fixing hole 38a of the frame member 23b. The clamp fixing member 14j is inserted into the clamp fixing hole 38c of the frame member 23b. The clamp fixing member 14k is inserted into the clamp fixing hole 38e of the frame member 23b. The clamp fixing member 14l is inserted into the clamp fixing hole 38g of the frame member 23b. The clamp fixing member 14m is inserted into the clamp fixing hole 38i of the frame member 23b.

[0022] The clamp fixing member 14o is inserted into the clamp fixing hole 37b of the frame member 23c. The clamp fixing members 14p to 14t are inserted through the clamp fixing holes 37g to 37k of the frame member 23c, respectively, as in the example of FIG. The clamp fixing member 14v is inserted into the clamp fixing hole 37q of the frame member 23c.

[0023] The clamp fixing member 14w is inserted into the clamp fixing hole 39b of the frame member 23d. The clamp fixing member 14x is inserted into the clamp fixing hole 39d of the frame member 23d. The clamp fixing member 14y is inserted into the clamp fixing hole 39f of the frame member 23d. The clamp fixing member 14z is inserted into the clamp fixing hole 39h of the frame member 23d. The clamp fixing member 14α is inserted into the clamp fixing hole 39j of the frame member 23d.

[0024] Although the single clamp 13g and the clamp fixing member 14g that fixes it, the single clamp 13n and the clamp fixing member 14n that fixes it, the single clamp 13w and the clamp fixing member 14w that fixes it, and the single clamp 13β and the clamp fixing member 14β that fixes it are not used and are therefore removed, they may remain attached. The same applies to the other examples described below.

[0025] As a result, the distance between the column bars clamped by single clamp 13a and the column bars clamped by single clamp 13h is shorter than in the example of Figure 1 by the sum of the distance between clamp fixing hole 37a and clamp fixing hole 37b and the distance between clamp fixing hole 37q and clamp fixing hole 37r. The same is true for the distance between the column bars clamped by single clamp 13o and the column bars clamped by single clamp 13v. In addition, the distance between the column reinforcement bars clamped by single clamps 13a to 13h and the column reinforcement bars clamped by single clamps 13o to 13v is shorter than the example in Figure 1 by the distance between frame fixing holes 34p and 34q (which is equal to the distance between frame fixing holes 35a and 35b). The distance between the column reinforcement clamped by single clamps 13i to 13m and the column reinforcement clamped by single clamps 13w to 13z, 13α is shorter than the example in Figure 1 by the sum of the distance between frame fixing holes 33a and 33b and the distance between frame fixing holes 33q and 33r. In this way, the same column reinforcement fixing jig 10 can be used for column reinforcement arrangements different from the example of Figure 1.

[0026] With reference to FIG. 11, an example in which the same column reinforcement fixing jig 10 is used for different column reinforcement arrangements will be described. The layout in this example is for an even higher floor than the example in Figure 10, and compared to the example in Figure 10, the thickness of the columns is the same, but the number of column reinforcement bars is even fewer. Since the only difference is the number of column reinforcement bars, it is the same as the example in Figure 10 except that single clamp 13b and clamp fixing member 14b, single clamp 13i and clamp fixing member 14i, single clamp 13p and clamp fixing member 14p, and single clamp 13w and clamp fixing member 14w have been removed.

[0027] With reference to FIG. 12, an example in which the same column reinforcement fixing jig 10 is used for different column reinforcement arrangements will be described. The layout in this example is for an even higher floor than the example in Figure 11, and compared to the example in Figure 11, the number of column reinforcement bars is the same, but the columns are thinner.

[0028] The frame fixing member 21a is inserted through the frame fixing hole 35p of the frame member 23d, the fixing hole 43b of the corner member 24a, and the frame fixing hole 33c of the frame member 23a. The corner fixing member 22a is inserted through the frame fixing hole 35l of the frame member 23d and the fixing hole 43a of the corner member 24a. The corner fixing member 22b is inserted through the fixing hole 43c of the corner member 24a and the frame fixing hole 33g of the frame member 23a.

[0029] The frame fixing member 21b is inserted through the frame fixing hole 34b of the frame member 23b, the fixing hole 43b of the corner member 24b, and the frame fixing hole 33p of the frame member 23a. The corner fixing member 22c is inserted through the fixing hole 43a of the corner member 24b and the frame fixing hole 33l of the frame member 23a. The corner fixing member 22d is inserted through the frame fixing hole 34f of the frame member 23b and the fixing hole 43c of the corner member 24b.

[0030] The frame fixing member 21c is inserted through the frame fixing hole 34o of the frame member 23b, the fixing hole 43b of the corner member 24c, and the frame fixing hole 33c of the frame member 23c. The corner fixing member 22e is inserted through the frame fixing hole 34k of the frame member 23b and the fixing hole 43a of the corner member 24c. The corner fixing member 22f is inserted through the fixing hole 43c of the corner member 24c and the frame fixing hole 33g of the frame member 23c.

[0031] The frame fixing member 21d is inserted through the frame fixing hole 35c of the frame member 23d, the fixing hole 43b of the corner member 24d, and the frame fixing hole 33p of the frame member 23c. The corner fixing member 22g is inserted through the fixing hole 43a of the corner member 24d and the frame fixing hole 33l of the frame member 23c. The corner fixing member 22h is inserted through the frame fixing hole 35g of the frame member 23d and the fixing hole 43c of the corner member 24d.

[0032] The clamp fixing member 14a is inserted into the clamp fixing hole 37c of the frame member 23a. As in the example of FIG. 11, the clamp fixing members 14c to 14f are inserted through the clamp fixing holes 37h to 37k of the frame member 23a, respectively. The clamp fixing member 14h is inserted into the clamp fixing hole 37p of the frame member 23a.

[0033] As in the example of FIG. 11, the clamp fixing members 14j to 14m are inserted through the clamp fixing holes 38c, 38e, 38g, and 38i of the frame member 23b.

[0034] The clamp fixing member 14o is inserted into the clamp fixing hole 37c of the frame member 23c. As in the example of FIG. 11, the clamp fixing members 14q to 14t are inserted through the clamp fixing holes 37h to 37k of the frame member 23c, respectively. The clamp fixing member 14v is inserted into the clamp fixing hole 37p of the frame member 23c.

[0035] The clamp fixing members 14x to 14z, 14α are inserted through the clamp fixing holes 39d, 39f, 39h, 39j of the frame member 23d, similarly to the example of FIG.

[0036] The single clamp 13b and clamp fixing member 14b, the single clamp 13i and clamp fixing member 14i, the single clamp 13p and clamp fixing member 14p, and the single clamp 13w and clamp fixing member 14w are not used and have been removed. If unused single clamps and clamp fixing members are left attached and not removed, there is a possibility that the clamp fixing members and corner fixing members (for example, clamp fixing member 14b and corner fixing member 22b) may interfere with each other. To prevent this, corner members 24a to 24d of different sizes may be prepared, and the corner member that does not interfere with the clamp fixing member may be used.

[0037] The distance between the column bars clamped by single clamp 13a and the column bars clamped by single clamp 13h is shorter than the example in Figure 11 by the sum of the distance between clamp fixing hole 37b and clamp fixing hole 37c and the distance between clamp fixing hole 37p and clamp fixing hole 37q. The same is true for the distance between the column bars clamped by single clamp 13o and the column bars clamped by single clamp 13v. In addition, the distance between the column reinforcement bars clamped by single clamps 13a to 13h and the column reinforcement bars clamped by single clamps 13o to 13v is shorter than the example in Figure 11 by the distance between frame fixing holes 34a and 34b and the distance between frame fixing holes 34o and 34p (which is equal to the sum of the distance between frame fixing holes 35b and 35c and the distance between frame fixing holes 35p and 35q). The distance between the column reinforcement bars clamped by single clamps 13j to 13m and the column reinforcement bars clamped by single clamps 13x to 13z, 13α is shorter than the example in Figure 11 by the sum of the distance between frame fixing holes 33b and 33c and the distance between frame fixing holes 33p and 33q. In this way, the same column reinforcement fixing jig 10 can be used for different column reinforcement arrangements.

[0038] With reference to FIG. 13, an example in which the same column reinforcement fixing jig 10 is used for different column reinforcement arrangements will be described. The layout in this example is for an even higher floor than the example in Figure 12, and compared to the example in Figure 12, the number of column reinforcement bars is the same, but the columns are thinner.

[0039] The frame fixing member 21a is inserted through the frame fixing hole 35o of the frame member 23d, the fixing hole 43b of the corner member 24a, and the frame fixing hole 33d of the frame member 23a. The corner fixing member 22a is inserted through the frame fixing hole 35k of the frame member 23d and the fixing hole 43a of the corner member 24a.

[0058] The distance between the column bars clamped by single clamp 13a and the column bars clamped by single clamp 13h is shorter than the example in Figure 13 by the sum of the distance between clamp fixing hole 37d and clamp fixing hole 37e and the distance between clamp fixing hole 37n and clamp fixing hole 37o. The same is true for the distance between the column bars clamped by single clamp 13o and the column bars clamped by single clamp 13v. In addition, the distance between the column reinforcement bars clamped by single clamps 13a to 13h and the column reinforcement bars clamped by single clamps 13o to 13v is shorter than the example in Figure 13 by the distance between frame fixing holes 34c and 34d and the distance between frame fixing holes 34m and 34n (which is equal to the sum of the distance between frame fixing holes 35d and 35e and the distance between frame fixing holes 35n and 35o).

In this way, the same column reinforcement fixing jig 10 can be used for different column reinforcement arrangements.

[0059] With reference to Figure 15, an example in which the same column reinforcement fixing jig 10 is used for different column reinforcement arrangements will be described. The layout in this example is for an even higher floor than the example in Figure 14, and compared to the example in Figure 14, the number of column reinforcement bars is the same, but the columns are thinner.

[0064] The clamp fixing member 14a is inserted into the clamp fixing hole 37f of the frame member 23a. The clamp fixing members 14c, 14d, and 14f are inserted through the clamp fixing holes 37h, 37i, and 37k of the frame member 23a, respectively, as in the example of FIG. The clamp fixing member 14h is inserted into the clamp fixing hole 37m of the frame member 23a.

[0065] The clamp fixing members 14j, 14k, and 14m are inserted through the clamp fixing holes 38c, 38e, and 38i of the frame member 23b, similarly to the example of FIG.

[0066] The clamp fixing member 14o is inserted into the clamp fixing hole 37f of the frame member 23c. The clamp fixing members 14q, 14r, and 14t are inserted through the clamp fixing holes 37h, 37i, and 37k of the frame member 23c, respectively, as in the example of FIG. The clamp fixing member 14v is inserted into the clamp fixing hole 37m of the frame member 23c.

[0067] The clamp fixing members 14x, 14y, and 14α are inserted into the clamp fixing holes 39d, 39f, and 39j of the frame member 23d, similarly to the example of FIG.

[0068] The distance between the column bars clamped by single clamp 13a and the column bars clamped by single clamp 13h is shorter than the example in Figure 14 by the sum of the distance between clamp fixing hole 37e and clamp fixing hole 37f and the distance between clamp fixing hole 37m and clamp fixing hole 37n. The same is true for the distance between the column bars clamped by single clamp 13o and the column bars clamped by single clamp 13v. In addition, the distance between the column reinforcement bars clamped by single clamps 13a to 13h and the column reinforcement bars clamped by single clamps 13o to 13v is shorter than the example in Figure 14 by the distance between frame fixing holes 34d and 34f and the distance between frame fixing holes 34k and 34m (which is equal to the sum of the distance between frame fixing holes 35e and 35g and the distance between frame fixing holes 35l and 35n). The distance between the column reinforcement bars clamped by single clamps 13j to 13m and the column reinforcement bars clamped by single clamps 13x to 13z, 13α is shorter than the example in Figure 14 by the sum of the distance between frame fixing holes 33e and 33g and the distance between frame fixing holes 33l and 33n. In this way, the same column reinforcement fixing jig 10 can be used for different column reinforcement arrangements.

[0069] With reference to Figure 16, an example in which the same column reinforcement fixing jig 10 is used for different column reinforcement arrangements will be described. The layout in this example is for an even higher floor than the example in Figure 15, and compared to the example in Figure 15, the thickness of the columns is the same, but the number of column reinforcement bars is actually greater. Since the only difference is the number of column reinforcement bars, it is the same as the example in Figure 15 except that the single clamp 13e and clamp fixing member 14e, single clamp 13l and clamp fixing member 14l, single clamp 13s and clamp fixing member 14s, and single clamp 13z and clamp fixing member 14z are reattached.

[0070] As described above, the frame portion 12 is formed by joining the frame members 23a to 23d in an annular shape, so the same column reinforcement fixing jig 10 can be used for columns of various thicknesses. Furthermore, since there are provided more clamp fixing holes 37a-37r, 38a-38k, 39a-39k than the number of single clamps 13a-13z, 13α, 13β to be attached to the frame members 23a-23d, the same column reinforcement fixing jig 10 can be used for various column reinforcement arrangements. The corner members 24a to 24d allow adjacent frame members 23a to 23d to form precise right angles, preventing distortion of the frame portion 12 and enabling accurate alignment of the column reinforcement bars. The column reinforcement is clamped with a single clamp, allowing for accurate alignment of the column reinforcement. Since the single clamp is fixed to the outside of the frame, it is possible to prevent the frame from interfering with anything on the outside of the pillar.

[0071] When setting PC columns, the position of the column reinforcement is extremely important. If the column reinforcement is fixed using plywood or other materials, if the position of the rebar is incorrect, the plywood will be damaged and positional accuracy will not be maintained. Also, if the position of the column reinforcement is incorrect, it will take a very long time to insert the plywood. In contrast, the column reinforcement is fixed with an L-angle and a single clamp, making it easy to install and remove, and because it is made of steel it will not break and precision can be ensured.Even if the length of the column reinforcement protruding from the top surface of the poured concrete is short, the inside of the column can be easily plastered evenly. In addition, bolt adjustments can accommodate narrower column dimensions. By determining the position of column reinforcement up to the top floor in advance, it is possible to accommodate the placement of column reinforcement on all floors. Therefore, what is used on lower floors can be used on upper floors as well, reducing costs. The L-shaped plate ensures precision in the right angles between the L-angles, ensuring accuracy.

[0072] The above-described embodiment is an example for facilitating understanding of the present invention. The present invention is not limited thereto, and includes various modifications, changes, additions, or omissions without departing from the scope defined by the appended claims. This can be easily understood by those skilled in the art from the above description.

[0073] The number of frame fixing members may be more than four. For example, if the cross section of the pillar is hexagonal, the number of frame fixing members may be six. In this case, the angle between adjacent frame fixing members may not be a right angle, but may be, for example, 120 degrees. [Explanation of symbols]
