[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
[0012] FIG. 1 is a perspective view of a reinforcing bar moving tool 1 according to a first embodiment of the present invention.
[0013] The reinforcing bar moving tool 1 has a pair of left and right side members 2, 2. Each side member 2, 2 has a first leg 5 formed at one axial end and a second leg 6 formed at the other axial end. The distance between one side member 2 and the other side member 2 can be set arbitrarily, and is preferably set to be greater than the distance between two adjacent reinforcing bars 10A, 10A such as main bars arranged in parallel, as shown in Fig. 6.
[0014] As shown in FIG. 1, when the reinforcing bar moving tool 1 is placed on the ground, the first legs 5, 5 and the second legs 6, 6 are configured to come into contact with the ground at four points in total.
[0015] As shown in Fig. 2, an inclined portion 11 is formed on one end of each side member 2, 2. The inclined portion 11 is spaced apart from the end of the first leg 5 as it moves from the end of the first leg 5 toward the second leg 6. As shown in Fig. 2, one end of the inclined portion 11 is bent to form the first leg 5. The inclined portion 11 and the first leg 5 form a first engagement portion 14.
[0016] At the other end of the inclined portion 11 of each side member 2, 2, an arc portion 12 formed in an arc shape is formed so that the center of the arc is located on the first leg portion 5 side. At the other end of the arc portion 12, a separation portion 13 is formed so as to be separated from the inclined portion 11. The other end of the separation portion 13 is bent in the direction opposite to the first leg portion 5 to form the second leg portion 6.
[0017] As shown in Figs. 1 to 3, first leg portion 5, inclined portion 11, arc portion 12, spaced portion 13 and second leg portion 6 are integrally formed by bending a single rod-shaped member such as a round bar or a reinforcing bar.
[0018] The inclined portion 11 of one side member 2 and the inclined portion 11 of the other side member 2 are connected by a connecting rod 15. The inclined portion 11 of one side member 2, the inclined portion 11 of the other side member 2, and the connecting rod 15 form a mounting portion 20. In addition, the left and right arc portions 12, 12 form a hook portion 21.
[0019] The hook portion 21 is adapted to be hooked onto reinforcing bars 10A, 10B, or, as shown in FIG. 8, onto steel pipes 30a, 30b, 30c, etc., having a circular or rectangular cross section.
[0020] Two cylindrical hooking portions 22a, 22b are provided in parallel on the inclined portion 11 side of each separated portion 13. The distance between the inclined portion 11 and the hooking portion 22b is greater than the distance between the inclined portion 11 and the hooking portion 22a.
[0021] As shown in Figure 8 (b), when the hooking portion 21 is hooked onto a steel pipe 30b with a square cross-section of □50, the hooking portion 22a on the side of the mounting portion 20 and the mounting portion 20 abut against the outside of the steel pipe 30b, thereby preventing the movement of the reinforcing bar moving device 1.
[0022] Furthermore, as shown in Figure 8(c), when the hook portion 21 is hooked onto a steel pipe 30b having a square cross-section of 60 mm, the hook portion 22b on the side of the second leg 6 and the inclined portion 11 abut against the outside of the steel pipe 30b, thereby suppressing movement of the rebar moving device 1.
[0023] A mounting plate 18 is installed between the other end side of the inclined portion 11 of one side member 2 and the other end side of the inclined portion 11 of the other side member 2, and side mounting plates 19, 19 protruding in the direction opposite to the first leg 5 side are provided at both ends of the mounting plate 18. Note that, as shown in FIG. 6, the mounting plate 18 is not installed at the ends of the side mounting plates 19, 19 on the second leg 6 side.
[0024] The other end 19a of the side mounting plate 19 on the inclined portion 11 side, which is the opposite side to the first leg portion, is formed in a tapered shape toward the other end side, which is located on the second leg portion 6 side opposite to the rotating portion 23 described later, as shown in Figures 2 and 8. A second engagement portion 28 is formed between the other end 19a and the hook portion 21.
[0025] A rotating part 23 that can rotate around a rotation axis 23a is provided between the side mounting plates 19, 19. In this embodiment, the rotating part 23 is configured as a cylindrical roller. It is preferable that the outer periphery of the rotating part 23 is configured from rubber or the like to provide an anti-slip surface on the outer periphery of the rotating part 23.
[0026] It is preferable that the side mounting plates 19, 19 are formed so as to be located outward from the outer circumferential surface of the rotating part 23 all around the circumference of the rotating part 23. It is preferable that the side mounting plates 19, 19 are formed so as to protrude more outwardly on the opposite side to the mounting part 20 from the outer circumferential surface of the rotating part 23. The mounting plate 18 and the side mounting plate 19 form a mounting part 24.
[0027] 1 and 4, when the rebar moving tool 1 is placed so that the first legs 5, 5 and the second legs 6, 6 are in contact with the ground at four points in total, a first guide portion 25 is formed at the upper end of each side mounting plate 19. The inner end of the first guide portion 25 is positioned more inward than the outer end of the rotating portion 23 in the axial direction.
[0028] 1, when the reinforcing bar moving tool 1 is arranged so that the placing part 20 abuts against the reinforcing bars 10A, 10B arranged in the vertical direction and the hooking part 21 is hooked onto the reinforcing bars 10A, 10B or a steel pipe, etc., a second guide part 26 is formed on the upper end of each side mounting plate 19. The inner end of the second guide part 26 is located inside the outer end of the rotating part 23 in the axial direction.
[0029] As described above, the two guide portions 25, 26 are fixed to each side mounting plate 19. In this embodiment, the guide portions 25, 26 are configured with bolts and nuts, but they can be configured with any material. Note that the guide portions 25, 26 do not necessarily have to be provided.
[0030] As shown in Figures 1 and 4, when the rebar moving tool 1 is positioned so that the first legs 5, 5 and the second legs 6, 6, a total of four points, are in contact with the ground, a space 30 is formed between the mounting portion 20 and the ground.
[0031] As shown in Fig. 4, the stirrups 10B etc. located at the lowest end of the underground beam are located within the space 30, and the first legs 5,5 and the second legs 6,6, a total of four points, are in contact with the ground, and the rotating part 23 can be installed without interfering with the installed reinforcing bars 10A,10B etc. In this case, the upper end of the rotating part 23 is located above the placement part 20 and the hook part 21, and the first guide part 25 is located above the rotating part 23.
[0032] As shown in Fig. 5, the reinforcing bar moving tool 1 has the mounting part 20 abutting against the reinforcing bars 10A, 10B arranged in the vertical direction, and the hook part 21 can be removably attached to the reinforcing bars 10A, 10B and the steel pipes 30a, 30b, 30c, etc. When attached, the rotating part 23 can be installed without interfering with the arranged reinforcing bars 10A, 10B, etc. At this time, the upper end of the rotating part 23 is located above the mounting part 20 and the hook part 21, and the second guide part 26 is located above the rotating part 23.
[0033] 6, by placing the placing part 20 on the reinforcing bars 10A, 10B arranged horizontally and engaging the second engaging part 28 with the reinforcing bars 10A, 10B, the reinforcing bar moving tool 1 can be detachably attached to the reinforcing bars 10A, 10B, and when attached, the rotating part 23 can be installed without interfering with the arranged reinforcing bars 10A, 10B, etc. By engaging the second engaging part 28 with the reinforcing bars 10A, 10B and placing the placing part 20 on the reinforcing bars 10A, 10B arranged horizontally, the reinforcing bar moving tool 1 can be stably attached to the reinforcing bars 10A, 10B without tilting during use.
[0034] 6, the placement part 20 can be placed on a plurality of reinforcing bars 10A, 10B arranged horizontally. The reinforcing bar mover 1 is prevented from moving during use by the second engagement part 28. In this case, the upper end of the rotating part 23 is positioned above the placement part 20 and the hook part 21, and the first guide part 25 is positioned above the rotating part 23.
[0035] In this way, the reinforcing bar moving tool 1 of the present invention can be installed in various locations at a construction site or factory using three different methods in relation to the reinforcing bars 10A, 10B and steel pipes 30a, 30b, 30c, etc. that have been arranged, and when installed, the upper end of the rotating part 23 is positioned above the mounting part 20 and the hooking part 21.
[0036] As described above, one or more reinforcing bar moving tools 1 are installed at appropriate positions at predetermined intervals so as to be removable, and then, as shown in Fig. 7, a part of the reinforcing bar 35, etc. is placed on the rotating part 23, and then the reinforcing bar 35, etc. is pushed so as to rotate the rotating part 23, so that the reinforcing bar 35, etc. can be easily moved to a predetermined position. Since the reinforcing bar 35, etc. is moved using the rotating part 23, interference with other reinforcing bars 10A, 10B is reduced, and friction when moving the reinforcing bar 35, etc. is reduced, improving workability and reducing the burden on the worker. Furthermore, the reinforcing bar 35, etc. can be moved to a predetermined position and arranged with fewer people than when the reinforcing bar moving tool 1 is not used.
[0037] When the reinforcing bar moving tool 1 is installed, the first guide portion 25 or the second guide portion 26 is positioned above the rotating portion 23, and the inner ends of the guide portions 25, 26 are positioned inside the axial outer end of the rotating portion 23. Therefore, when moving reinforcing bars 35 etc. with the reinforcing bar moving tool 1, the guide portions 25, 26 can prevent the reinforcing bars 35 etc. from falling off the rotating portion 23 and can prevent the reinforcing bars 35 etc. from coming into contact with the side mounting plate 19.
[0038] Furthermore, by placing the reinforcing bar moving tool 1 in an appropriate position, when passing reinforcing bars 35 etc. between the installed reinforcing bars 10A, 10B, interference with other reinforcing bars 10A, 10B can be more easily avoided than when the reinforcing bar moving tool 1 is not used, and the reinforcing bar arrangement work can be carried out smoothly and efficiently.
[0039] In the reinforcing bar moving tool 1 of the above embodiment, the members other than the rotating portion 23 and the mounting portion 24 are formed by bending a rod-shaped member, but they may be formed by bending a plate material. [Explanation of symbols]
