Description

[Technical Field]

[0001] The present invention relates to a pole mounting jig, and more particularly to a pole mounting jig that is attached to a pole and is used to set up a temporary scaffold or a temporary ladder on the pole. [Background technology]

[0002] BACKGROUND ART Conventionally, temporary scaffolding and temporary ladders have been used to perform high-altitude work such as joining pillars and beams during the construction of a building. For example, the work platform installation jig described in Patent Document 1 is attached to a predetermined position on a pillar for the purpose of performing work at height during construction of a building, and makes it possible to install a work platform on the pillar. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-53122 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the case of a work floor installation jig such as that disclosed in Patent Document 1, there has been a demand for a jig that has a simpler configuration and is capable of installing temporary scaffolding or temporary ladders on pillars.

[0005] In addition, there are cases where metal posts are attached to the side of a pillar for assembling temporary scaffolding (temporary ladders), but the metal posts are not installed at an appropriate height. For example, such metal posts cannot be installed at the joints where pillars are joined. Even in such cases, there has been a demand for a jig that allows temporary scaffolding (temporary ladders) to be installed at a height that makes it easy to work on the pillars.

[0006] An object of the present invention is to provide a pillar mounting jig that has a simpler configuration than conventional ones and that enables temporary scaffolding (temporary ladders) to be installed on pillars. Another object of the present invention is to provide a pillar mounting jig that allows a temporary scaffold (temporary ladder) to be installed at a height that makes it easy to work on the pillar. [Means for solving the problem]

[0007] The above problem is solved by the pillar mounting jig of the present invention, which is attached to a pillar that is long in the vertical direction and is used to install temporary scaffolding or a temporary ladder on the pillar, and which comprises: a jig main body portion that extends long in the vertical direction along the side of the pillar; a pillar hang-on portion that is provided on the inner surface of the jig main body portion, arranged opposite the side of the pillar, and is detachably hooked onto a pillar hardware fixed to the side of the pillar; and an attachment portion that is provided on the outer surface of the jig main body portion, arranged at a different height from the pillar hang-on portion, and is detachably attached to an attachment portion fixed to the temporary scaffolding or the temporary ladder. With the above configuration, it is possible to realize a pillar mounting jig that has a simple configuration and is capable of setting up a temporary scaffolding (temporary ladder) on a pillar. More specifically, the pole mounting jig has a pole hook part that is hooked onto the pole hardware, and a mounting part that is positioned at a different height from the pole hook part and is attached to the mounting part of the temporary scaffolding (temporary ladder). Therefore, it is possible to assemble the temporary scaffolding (temporary ladder) to the pole with a simpler structure than conventional jigs. In addition, the pillar hook-stop part and the mounting part are positioned at different heights, and by adjusting the height position of the mounting part, the temporary scaffolding (temporary ladder) can be set up at a height that makes it easy to work on the pillar.

[0008] In this case, the pillar hanging portion is removably hung from above on the pillar hardware, the mounting portion has the mounting portion of the temporary scaffolding or temporary ladder removably attached from above, and the pillar mounting jig is attached to the pillar and supports the temporary scaffolding or temporary ladder from below. With the above configuration, the pole mounting jig can be firmly hooked to the pole, and a temporary scaffold (temporary ladder) can be firmly attached to the pole mounting jig.

[0009] In this case, the pillar mounting jig is attached so as to straddle the pillar joint that joins the first pillar and second pillar, which are long in the vertical direction, the pillar hanging portion is hung on the pillar hardware fixed to the side of the first pillar and / or the second pillar, and the mounting portion is positioned at a height position corresponding to the pillar joint, and supports the temporary scaffolding or the temporary ladder. With the above configuration, by using the pillar mounting jig, it is possible to set up temporary scaffolding (temporary ladders) at a height position corresponding to the pillar joint where the pillars are joined. In other words, although it is difficult to attach pillar hardware to the pillar joint, by using this pillar mounting jig, it is possible to set up temporary scaffolding at a suitable height position corresponding to the pillar joint.

[0010] In this case, a long through hole in the vertical direction is formed on the side of the jig main body at a different height position from the mounting portion, in the peripheral portion of the pillar hang stopper portion, and when the pillar mounting jig is attached to the pillar, the pillar hardware and the pillar hang stopper portion are exposed through the through hole. With the above configuration, it is possible to visually confirm that the post hook fastening portion is hooked onto the post metal fitting. Also, the through hole can be used as a handle for the worker.

[0011] In this case, the pillar hanging portion is arranged to protrude from the inner surface of the jig main body portion toward the pillar, and a long spacer extending in the vertical direction is attached to a portion of the inner surface of the jig main body portion that is at a different height from the pillar hanging portion, so that when the pillar hanging portion is hung on the pillar hardware, the spacer abuts against the side of the pillar. With the above configuration, the pole mounting jig can be mounted more stably on the side surface of the pole, which means that the temporary scaffolding (temporary ladder) can be set up stably on the pole.

[0012] In this case, the pillar hanging stopper portion is positioned in the upper part of the jig main body portion, the mounting portion is provided at a position lower than the pillar hanging stopper portion, and a cutout portion is preferably formed on the side of the jig main body portion in the portion lower than the mounting portion to avoid interference with the pillar member provided on the side of the pillar. With the above configuration, the pole attachment device can be suitably attached to the side surface of the pole while avoiding interference with the pole member on the side surface of the pole.

[0013] In this case, the jig main body portion has a first wall portion extending in the vertical direction along a first side surface adjacent to the corner of the pillar, and a second wall portion connected to the first wall portion and extending in the vertical direction along a second side surface adjacent to the corner of the pillar, the pillar hanging portion has a first pillar hanging portion provided on the inner surface of the first wall portion and hung on a first pillar hardware fixed to the first side surface, and a second pillar hanging portion provided on the inner surface of the second wall portion and hung on a second pillar hardware fixed to the second side surface, and the mounting portion has a first mounting portion provided on the outer surface of the first wall portion and a second mounting portion provided on the outer surface of the second wall portion. With the above configuration, the pole mounting jig can be attached to the first and second side faces adjacent to the corner of the pole, and the pole mounting jig can be installed so as to surround the corner of the pole. This allows the temporary scaffolding (temporary ladder) to be more firmly attached to the pole. [Effects of the Invention]

[0014] According to the pillar mounting jig of the present invention, it is possible to install temporary scaffolding or temporary ladders on pillars with a simpler configuration than conventional ones. It also makes it possible to set up temporary scaffolding and ladders at a height that makes it easier to work on the pillars. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a "pillar mounting jig" that is attached to a vertically long pillar and enables temporary scaffolding (temporary ladder) to be installed on the pillar with a simple configuration.

[0017] <Overall structure> As shown in Figs. 1 to 5, the pillar mounting jig 1 is a jig that is attached to pillars B1 and B2 that constitute a skeleton B during construction of a building, and is used to set up a temporary scaffolding S on the pillars B1 and B2. Specifically, the pillar mounting jig 1 is attached so as to straddle the pillar joint B3 which joins the first pillar B1 and the second pillar B2, which are long in the vertical direction, and is a jig for installing the temporary scaffolding S at the height position of the pillar joint B3. This allows the temporary scaffolding S to be installed at a height that is convenient for work at heights, such as when joining the columns B1, B2 and the beams B4 or when painting. Also, the temporary scaffolding S can be installed more stably relative to the columns B1, B2. Below, the building frame B and the temporary scaffolding S will be explained, and then the column mounting jig 1 will be explained in detail.

[0018] As shown in Figures 1 to 3, the building's main body B comprises a first column B1 and a second column B2 that are long in the vertical direction, a column joint B3 that joins the first column B1 and the second column B2, and a beam B4 that is connected to the side of the second column B2 and extends in the frontage direction or projection direction of the main body B.

[0019] A first column metal fitting B5 and a second column metal fitting B6 are fixed by welding to the first side surface B2a and the second side surface B2b adjacent to the corners of the second column B2, respectively. Furthermore, pillar members B7 are attached to the first side surface B1a and the second side surface B1b adjacent to the corners of the first pillar B1. The pillar hardware B5 and B6 are used, for example, to attach a jig when erecting a pillar, or to directly attach a temporary scaffold (temporary ladder) to the pillar. In this embodiment, the pillar mounting jig 1 is attached to the pillar hardware B5 and B6.

[0020] The second column B2 and the beam B4 are connected using a fastening bolt B8 (double-threaded bolt) and a nut B9. Specifically, the column plate B2c fixed to the side surface of the second column B2 is brought into contact with the beam end plate B4a fixed to one end of the beam B4, and the fastening bolt B8 is fastened and the nut B9 is tightened while the screw hole of the column plate B2c and the through hole of the beam end plate B4a are connected. In this way, the second column B2 and the beam B4 are connected.

[0021] In the above configuration, as shown in Figures 2 and 4, the pillar mounting jig 1 (pillar hanging portions 20, 25) is hung on pillar hardware B5, B6 fixed to the side of the second pillar B2, so that the pillar mounting jig 1 is removably attached to the pillars B1, B2. At this time, the column mounting jig 1 is configured to face both side surfaces of the second column B2 and to be in surface contact with the second column B2. This allows the pillar mounting jig 1 to be firmly mounted to the pillars B1 and B2.

[0022] As shown in FIGS. 3 and 5, the temporary scaffolding S is a member (temporary stage) that is detachably attached to the pillars B1 and B2 via a pillar attachment jig 1 and serves as a foothold for workers. The temporary scaffolding S includes a rectangular top plate member S1 that serves as a foothold for workers, and a top plate support portion S2 that supports the top plate member S1 from below. A recess S3 is formed in the corner portion of the outer edge of the top plate member S1 that faces the column mounting jig 1.

[0023] The recessed portion S3 is formed by cutting a corner portion of the top plate member S1. The recessed portion S3 has a cross-sectional shape that follows the outer shape of the corner of the pole mounting jig 1. Specifically, the recessed portion S3 is cut into a substantially rectangular shape when viewed from above. A first mounting portion S4 and a second mounting portion S5 are fixed to the inner surface of the recessed portion S3. The first attachment portion S4 has an attachment body S4a, an attachment claw S4b, a contact portion S4c, and a clearance portion S4d, as shown in Fig. 9. The second attachment portion S5 has a similar structure.

[0024] In the above configuration, as shown in Figures 3 and 5, by attaching the attachment portions S4 and S5 to the scaffolding attachment portions 30 and 35 of the pillar attachment jig 1, the temporary scaffolding S is attached to the pillar attachment jig 1 in a detachable manner. At this time, the recessed portion S3 of the temporary scaffolding S is configured to face the side surface of the pillar mounting jig 1 and to come into surface contact with the pillar mounting jig 1. This allows the temporary scaffolding S to be firmly attached to the pillar mounting jig 1.

[0025] <Details of the pillar mounting jig> As shown in Figures 4 to 9, the pillar mounting jig 1 comprises a jig main body 10 extending longitudinally in the vertical direction along the side surfaces of pillars B1 and B2, pillar hanging portions 20 and 25 provided on the inner surface of the jig main body 10, scaffolding mounting portions 30 and 35 provided on the outer surface of the jig main body 10 and positioned at a different height from the pillar hanging portions 20 and 25, and spacers 40 and 45 provided on the inner surface of the jig main body 10 and positioned at a different height from the pillar hanging portions 20 and 25. A first through hole 50 and a second through hole 55 that are long in the vertical direction are formed on the side surface of the jig body 10. In addition, a first cutout portion 60 and a second cutout portion 65 are formed on the lower end portion of the jig body 10.

[0026] The jig main body 10 has a first wall 11 extending vertically along first side surfaces B1a, B2a adjacent to the corners of the pillars B1, B2, and a second wall 12 connected to one end of the first wall 11 in the width direction and extending vertically along second side surfaces B1b, B2b adjacent to the corners of the pillars B1, B2. That is, the jig body 10 has a substantially L-shaped cross section.

[0027] The first pillar retaining portion 20 is disposed in the upper portion (upper end portion) of the jig body 10 (first wall portion 11) and attached to the inner surface of the first wall portion 11, as shown in FIGS. The first pillar hooking portion 20 is disposed so as to face the first side surface B2a of the second pillar B2, and is detachably hooked to the first pillar hardware B5 fixed to the first side surface B2a.

[0028] The first pillar hook portion 20 has a hook body 21 fixed so as to protrude from the inner surface of the first wall portion 11, and a hook claw 22 protruding downward from the lower end of the hook body 21. The latching claw 22 is arranged on the extending end side in the width direction of the first wall portion 11 (the end side different from the second wall portion 12 side), and is arranged at a position slightly away from the first through hole 50. At the lower end of the latch body 21, a contact portion 23 that protrudes slightly downward is formed in a portion close to the latch claw 22. At the lower end of the latch body 21, a relief portion 24 is formed in a portion away from the latch claw 22.

[0029] In the above configuration, as shown in Fig. 8, the first pillar hook portion 20 is detachably hooked from above to the first pillar hardware B5. Specifically, the hook claw 22 is inserted (dropped) into the hook hole B5a of the first pillar hardware B5 from above. At this time, the contact portion 23 comes into contact with the upper end (upper edge portion) of the first pillar hardware B5, thereby firmly hooking the pillar mounting jig 1. In addition, the height position of the pillar mounting jig 1 relative to the pillars B1 and B2 can be determined. By forming the relief portion 24, the first through hole 50 can be made larger.

[0030] The second pillar retaining portion 25 is disposed in the upper portion (upper end portion) of the jig body 10 (second wall portion 12) and attached to the inner surface of the second wall portion 12, as shown in FIGS. The second pillar hook portion 25 is provided symmetrically to the first pillar hook portion 20 with respect to the corner of the jig body portion 10 . Similar to the first pillar hook portion 20, the second pillar hook portion 25 has a hook main body 26, a hook claw 27, an abutment portion 28, and a relief portion 29. The second pillar hook portion 25 is detachably hooked from above to the second pillar hardware B6. Specifically, the hook claw 27 is inserted from above into the hook hole B6a of the second pillar hardware B6.

[0031] As shown in Figures 5, 6 and 9, the first scaffolding mounting part 30 is attached to the outer surface of the jig main body part 10 (first wall part 11) and is positioned lower than the first pillar hanging part 20. The first scaffolding mounting portion 30 has a first mounting target portion S4 of the temporary scaffolding S detachably mounted thereto from above.

[0032] The first scaffolding mounting portion 30 has left and right fixed wall portions 31 fixed to the outer surface of the first wall portion 11 at a predetermined interval, left and right protruding wall portions 32 protruding outward from the left and right fixed wall portions 31, respectively, and a connecting wall portion 33 connecting the left and right protruding wall portions 32. The first scaffolding mounting portion 30 is formed by left and right protruding wall portions 32 and a connecting wall portion 33, and has a mounting hole 34 that is inserted in the vertical direction. A plurality of first scaffolding mounting portions 30 are arranged at intervals in the vertical direction of the pillar mounting jig 1.

[0033] 9, the first mounted portion S4 of the temporary scaffolding S is detachably mounted from above to the first scaffolding mounting portion 30. Specifically, the mounting claws S4b are inserted (dropped) into the mounting holes 34 from above. At this time, the abutting portion S4c of the first mounted portion S4 abuts against the upper end (upper edge portion) of the first scaffolding mounting portion 30, thereby firmly mounting the temporary scaffolding S. In addition, the height position of the temporary scaffolding S relative to the pillar mounting jig 1 can be determined.

[0034] As shown in FIGS. 5 and 6, the second scaffolding attachment portion 35 is attached to the outer surface of the jig body portion 10 (second wall portion 12), and is disposed below the second pillar hook portion 25. The second scaffolding attachment portion 35 is provided symmetrically to the first scaffolding attachment portion 30 with respect to the corner of the jig body portion 10 . The second scaffolding mounting portion 35 has left and right fixed wall portions 36 , left and right protruding wall portions 37 , a connecting wall portion 38 , and a mounting hole 39 . The second scaffolding mounting portions 35 are arranged at intervals in the vertical direction of the pillar mounting jig 1. As shown in FIG. 5, the second mounted portion S5 of the temporary scaffolding S is detachably fastened to the second scaffolding mounting portion 35 from above.

[0035] With the above configuration, as shown in FIG. 5, the pole mounting jig 1 is suspended from the poles B1 and B2 and can support the temporary scaffolding S from below. At this time, the scaffolding attachment parts 30, 35 are placed at a height position corresponding to the column joint part B3, and support the temporary scaffolding S at a height position corresponding to the column joint part B3. This allows the temporary scaffolding S to be set up at a height that is easy for workers to work with respect to the columns. In particular, it is difficult to attach the column hardware B5, B6 to the column joint B3, and by using this column attachment jig 1, the temporary scaffolding S can be set up at a height that corresponds to the column joint B3.

[0036] As shown in Figures 6 and 7, the first spacer 40 is a plate-shaped member (plate member) that is long in the vertical direction and is attached to the inner surface of the jig main body portion 10 (first wall portion 11), and is positioned at a different height from the first pillar hanging portion 20 and the first cutout portion 60. A plurality of first spacers 40 are arranged at intervals in the vertical direction, and are attached to the extending end of the first wall portion 11 in the width direction. Specifically, the first spacer 40 is disposed at a position corresponding to the latching claw 27 (directly below the latching claw 27).

[0037] The second spacer 45 is provided symmetrically to the first spacer 40 with respect to the corner of the jig body 10 . A plurality of second spacers 45 are arranged at intervals in the vertical direction, and are attached to the end portion of the second wall portion 12 extending in the width direction.

[0038] In the above configuration, as shown in FIGS. 4 and 7, the pillar hooking portions 20, 25 are provided so as to protrude from the inner surface of the jig body 10 toward the pillars B1, B2. When the pillar hooking portions 20, 25 are hooked onto the pillar hardware B5, B6, respectively, the spacers 40, 45 come into contact with the side surfaces of the pillars B1, B2, respectively. Therefore, the pillar mounting jig 1 can be mounted more stably on the side surfaces of the pillars B1 and B2, that is, the pillar mounting jig 1 can be prevented from shaking (wobbling).

[0039] In the above configuration, as shown in Figures 5 and 6, a first through hole 50 and a second through hole 55 that are long in the vertical direction are formed on the side of the jig main body 10 at a height position different from that of the scaffolding mounting parts 30 and 35, in the peripheral area of ​​the pillar hanging stop parts 20 and 25. When the pillar mounting jig 1 is mounted on pillars B1 and B2, the first pillar hardware B5 and the first pillar hanging portion 20 are configured to be exposed through the first through-hole 50. Also, the second pillar hardware B6 and the second pillar hanging portion 25 are configured to be exposed through the second through-hole 55. By doing so, it is possible to visually confirm that the pillar hooking portions 20, 25 are hooked onto the pillar hardware B5, B6. The first through holes 50 and the second through holes 55 are formed at intervals in the vertical direction. Therefore, the first through holes 50 and the second through holes 55 can also be used as handles for the operator.

[0040] In the above configuration, as shown in Figures 4 to 6, cutout portions 60, 65 are formed on the side of the jig main body portion 10 below the scaffolding mounting portions 30, 35 to avoid interference with the pillar member B7 on the side of the first pillar B1. The first cutout 60 is formed in the lower end of the first wall 11 , and the second cutout 65 is formed in the lower end of the second wall 12 . By doing so, the pillar mounting jig 1 can be preferably mounted while avoiding interference with the pillar member B7 of the first pillar B1. 6, the upper end of the jig body 10 (first wall 11, second wall 12) is formed with a third notch 70 and a fourth notch 75. This makes it possible to avoid interference with other components on the side surface of the second column B2.

[0041] <Other embodiments> In the above embodiment, as shown in FIG. 4, the pillar mounting jig 1 (jig main body 10) has a substantially L-shaped cross section, but this is not particularly limited. For example, the pillar mounting jig 1 may be a plate-shaped (flat) jig. That is, the pillar mounting jig 1 may include a plate-shaped jig main body, a pillar hooking portion, and a scaffolding mounting portion. The pillar mounting jig 1 may be hooked to one side of the pillars B1 and B2 so as to face each other.

[0042] In the above embodiment, as shown in FIG. 5, the pillar mounting jig 1 is used to set up the temporary scaffolding S, but it may also be used to set up a temporary ladder instead of the temporary scaffolding S. In this case, the temporary ladder preferably has a ladder body and an attachment portion (attachment claw) provided on the upper portion (upper end) of the ladder body.

[0043] In the above embodiment, as shown in FIG. 8, the pole mounting jig 1 (pole hooking portions 20, 25) is hooked from above onto pole hardware B5, B6 fixed to the pole, but this is not particularly limited. The pillar hooking portions 20, 25 may be hooked to the pillar hardware B5, B6 from the side or from below.

[0044] In the above embodiment, the pole mounting jig according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof. [Explanation of symbols]
