Summary of the Invention

Problems to be Solved by the Invention

[0004] When using the suspension jig described in Patent Document 2, a plurality of outer wall members can be hoisted by a single crane operation. However, each time an outer wall member is attached to its attachment position, it is necessary to move the suspension jig by the crane. Further, when fixing the outer wall member to the attachment position, since there is a next outer wall member immediately behind, it may interfere with the attachment work. An object of the present invention is to solve such problems, for example.

Means for Solving the Problems

[0005] The panel transport device transports multiple panels by being lifted by a lifting device. The panel transport device comprises multiple suspension parts for each of the multiple panels, a forward and backward movement mechanism for moving the multiple suspension parts in the forward and backward directions, a second suspension part located in front of the forward and backward movement mechanism for suspending one of the multiple panels, and a vertical movement mechanism for moving the second suspension part in the vertical direction. The panel transport device may further include a posture stabilization mechanism for stabilizing the posture of the panel transport device when it is lifted by the lifting device. The panel installation method involves suspending multiple panels from each of the multiple suspension parts of a panel transport device according to claim 1 or 2, which is lifted by a lifting device; moving the panel transport device with the lifting device; positioning the multiple panels suspended from the panel transport device near the panel installation location of the building; moving the multiple panels one by one to the panel installation location using the forward / backward movement mechanism and the up / down movement mechanism; and attaching the panels to the panel installation location. [Effects of the Invention]

[0006] According to the panel transport device and panel installation method described above, multiple panels can be lifted together, thus reducing working time and shortening the construction period. Since the panels to be installed at the panel mounting position are moved up and down by the second suspension part, if the panel mounting positions are aligned vertically, there is no need to move the panel transport device with a lifting device, which reduces working time and shortens the construction period. By moving panels other than the one being installed at the panel mounting location to the rear, it prevents them from getting in the way of the installation work. The posture stabilization mechanism stabilizes the posture of the panel transport device, allowing for safe installation even when lifting multiple panels at once. Since there is no need to erect external scaffolding on the building, construction time and costs can be reduced. [Brief explanation of the drawing]

[0008] As shown in Figures 1 to 3, the panel transport device 10 includes, for example, a main body 11, eight suspension parts 12a to 12h, two second suspension parts 13a and 13b, a forward / backward movement mechanism 14, two vertical movement mechanisms 15a and 15b, a posture stabilization mechanism 16, and a tilt adjustment mechanism 17 (see Figure 6).

[0009] The main body 11 includes, for example, a frame 111, four legs 112a to 112d, a counterweight 113, and two chain covers 114a and 114b. The frame section 111 is, for example, a frame shape having two horizontal beams extending parallel to the FB direction and four vertical beams spanning between them and extending parallel to the LR direction. The legs 112a to 112d extend from the frame 111 in direction D, and support the frame 111 when the panel transport device 10 is placed on the ground or the like. The chain cover 114a is provided on the B side of the frame portion 111 and covers the electric motor 42 (see FIG. 4) of the forward and backward movement mechanism 14 described later. The chain cover 114b is provided on the F side of the frame portion 111 and covers the pulley 44 (see FIG. 4) of the forward and backward movement mechanism 14. The counterweight 113 is provided on the R side of the frame portion 111 in order to balance the panel conveying device 10 in the L-R direction, thereby balancing with the forward and backward movement mechanism 14 provided at a position closer to the L side of the panel conveying device 10.

[0010] The hanging parts 12a to 12h hang panels such as outer wall panels attached to a building. Each of the hanging parts 12a to 12h hangs one panel at a time (for example, the panels 91a to 91h shown in FIG. 6). The hanging parts 12a to 12h each have, for example, a hook 21, a roller 22, and an engaging part 23. The hook 21 hangs a wire rope (for example, the wire ropes 93a to 93h shown in FIG. 6) wound around the panel to hang the panel. The roller 22 is placed on the rail 43 of the forward and backward movement mechanism 14 described later and supports the hanging parts 12a to 12h so that they can move in the F-B direction. The engaging part 23 engages with the chain 41 of the forward and backward movement mechanism 14 described later, transmits the movement of the chain 41 to the hanging parts 12a to 12h, and moves the hanging parts 12a to 12h in the F-R direction.

[0011] The second hanging parts 13a and 13b hang one panel (for example, the panel 91h shown in FIG. 8) together. The hanging parts 13a and 13b each have, for example, a hook 31. <{ The hook 31 hangs a wire rope (for example, the wire ropes 93i and 93j shown in FIG. 8) wound around the panel to hang the panel.

[0012] The front-back movement mechanism 14 moves the hanging parts 12a to 12h in the F-B direction according to, for example, a wireless operation. As shown in FIG. 4, the front-back movement mechanism 14 has, for example, a chain 41, a motor 42, a rail 43, and a gear 44. The gear 44 is provided inside the chain cover 114b and can rotate about an axis parallel to the U-D direction. The motor 42 is provided inside the chain cover 114a and rotates a gear that rotates about an axis parallel to the U-D direction clockwise and counterclockwise. The chain 41 is an annular special chain and is spanned between the gear rotated by the motor 42 and the gear 44. When the motor 42 rotates the gear, the chain 41 moves, and the hanging parts 12a to 12h engaged with the chain 41 move in the F direction or the B direction.

[0013] The up-down movement mechanism 15a moves the hanging part 13a in the U-D direction. The up-down movement mechanism 15b moves the hanging part 13b in the U-D direction. The up-down movement mechanisms 15a and 15b are, for example, electric chain hoists. The up-down movement mechanisms 15a and 15b each have, for example, a motor 51 and a push button switch 52. When an operator operates the push button switch 52, the motor 51 operates, and thereby, the hanging parts 13a and 13b move in the U direction or the D direction.

[0014] The attitude stabilization mechanism 16 is, for example, a suspended load device described in Patent Document 1. When the panel transfer device 10 is lifted by a hoisting device such as a crane, the attitude of the panel transfer device 10 is stabilized so that the direction of the panel transfer device 10 does not change due to wind pressure, centrifugal force, or the like.

[0015] As shown in Figure 6, the tilt adjustment mechanism 17 is, for example, an electric blockchain, and is interposed between the wire rope 18c fixed to the F side of the attitude stabilization mechanism 16 and the wire rope 18b that is attached to the hook 81 of a lifting device 80 such as a crane. On the other hand, the wire rope 18a is fixed to the B side of the attitude stabilization mechanism 16 and attached to the hook 81. By operating the tilt adjustment mechanism 17, the overall length consisting of the wire rope 18b, tilt adjustment mechanism 17, and wire rope 18c can be adjusted, and by balancing with the wire rope 18a, the tilt of the panel conveying device 10 in the FB direction is adjusted to keep the panel conveying device 10 horizontal.

[0016] Next, we will describe a panel installation method using the panel transport device 10 described above to attach panels such as exterior wall panels to a building under construction.

[0017] As shown in Figure 5, the panel installation method includes, for example, a suspension process S1, a lifting process S2, a forward movement process S3, a replacement process S4, a downward movement process S5, a backward movement process S6, and an attachment process S7.

[0018] First, in the lowering process S1, as shown in Figure 6, the panel transport device 10 is lifted by the lifting device 80 and moved above the panels 91a to 91h. The panels 91a to 91h may be, for example, loaded on the bed of a delivery vehicle, or they may be unloaded from a delivery vehicle and temporarily placed on the ground. Cushioning materials 92a to 92g are placed between the panels 91a to 91h, respectively. Then, wire ropes 93a to 93h are wrapped around each of the panels 91a to 91h to secure them, and these wire ropes 93a to 93h are attached to the hooks 21 of the suspension parts 12a to 12h. At this time, the suspension parts 12a to 12h are positioned at equal intervals towards side B by the forward and backward movement mechanism 14.

[0019] Next, in the lifting process S2, the panel transport device 10 is lifted by the lifting device 80 and moved to a location near the panel installation site where the panels 91a to 91h should be installed, such as the exterior wall of the building under construction. At this time, the overall posture of the panel transport device 10 is stabilized by the posture stabilization mechanism 16. In addition, since cushioning materials 92a to 92g are placed between the panels 91a to 91h, the panels 91a to 91h are transported as a whole unit without their orientations becoming scattered.

[0020] Subsequently, in the forward movement process S3, as shown in Figure 7, the forward / backward movement mechanism 14 moves the suspension parts 12a to 12h in the direction of F, and positions the suspension part (i.e., suspension part 12h) that is closest to F among the suspension parts 12a to 12h that suspend the panels 91a to 91h at the replacement position P. The forward / backward movement mechanism 14 may also have a safety device to prevent the suspension parts 12a to 12h that suspend the panels from moving beyond the replacement position P towards F.

[0021] Next, in the replacement process S4, as shown in Figure 8, the panel (91h) suspended from the suspension part (12h) located at the replacement position P is replaced with the suspension parts 13a and 13b. For example, a worker secures the wire rope 93i by wrapping it around the panel 91h and attaches it to the hook 31 of the suspension part 13a. Similarly, another worker secures the wire rope 93j by wrapping it around the panel 91h and attaches it to the hook 31 of the suspension part 13b. Then, by operating the push-button switch 52 to activate the vertical movement mechanisms 15a and 15b and moving the suspension parts 13a and 13b slightly in the U direction, the load on the wire rope 93h is released and the wire rope 93h is removed from the hook 21 of the suspension part 12h.

[0022] Subsequently, in the downward movement process S5, as shown in Figure 9, the push-button switch 52 is operated to activate the vertical movement mechanisms 15a and 15b, moving the suspension parts 13a and 13b in the D direction, and moving the panel (91h) suspended from the suspension parts 13a and 13b to a position very close to the panel mounting position where it should be attached.

[0023] Next, in the rearward movement process S6, as shown in Figure 10, the forward / backward movement mechanism 14 moves the suspension parts 12a to 12h in the direction of B. This prevents them from interfering with the installation work of the panels suspended from the suspension parts 13a and 13b. The forward / backward movement mechanism 14 may also have a safety device to prevent the suspension parts 12a to 12h from moving beyond the retracted position Q towards B.

[0024] Subsequently, in installation process S7, the panels (91h) suspended from the suspension parts 13a and 13b are attached to the building. For example, the push-button switch 52 is operated to activate the vertical movement mechanisms 15a and 15b, aligning the panel (91h) suspended from the suspension parts 13a and 13b to the panel mounting position. Since the vertical movement mechanisms 15a and 15b can independently move the suspension parts 13a and 13b in the UD direction, the panel can be precisely positioned to the panel mounting position. Then, a worker on the bucket of the aerial work platform fixes the panel to the panel mounting position.

[0025] After the installation process S7 is completed, if there are still panels remaining suspended from the suspension sections 12a to 12h, the process returns to the forward movement process S3 and the next panel is installed on the building. For example, if the installation of panel 91h suspended from suspension section 12h is complete, and panels 91a to 91g are still suspended from the remaining suspension sections 12a to 12g, in the forward movement process S3, the suspension section 12h without a panel will pass the replacement position P, and the suspension section 12g with panel 91g will be positioned at the replacement position P. Then, in the replacement process S4, panel 91g suspended from suspension section 12g will be replaced with suspension sections 13a and 13b, and after the downward movement process S5 and the backward movement process S6, panel 91g will be installed in the panel installation position in the installation process S7. This process is repeated until all panels are used, and each panel is attached to the building one by one. If there are any more panels to be attached, the process returns to the suspension step S1, and the next panel is lifted and attached to the building.

[0026] In this way, multiple panels can be lifted together, which reduces working time and shortens the construction period. Since the panels to be installed at the panel mounting position are moved up and down by the second suspension part, if the panel mounting positions are aligned vertically, there is no need to move the panel transport device with a lifting device, which reduces working time and shortens the construction period. By moving panels other than the one being installed at the panel mounting location to the rear, it prevents them from getting in the way of the installation work. The posture stabilization mechanism stabilizes the posture of the panel transport device, allowing for safe installation even when lifting multiple panels at once. Since there is no need to erect external scaffolding on the building, construction time and costs can be reduced.

[0027] Since each exterior panel is relatively light, weighing approximately 50 kg, continuous installation significantly improves construction efficiency. For example, about 10 panels can be suspended and installed one by one while a special chain is rotary-rotated. An electric chain hoist is used for balancing the suspended load, and in synergy with the posture stabilization mechanism, safe and highly efficient construction is possible.

The present invention is not limited thereto and includes various modifications, changes, additions, or deletions without departing from the scope defined by the appended claims. This will be readily apparent to those skilled in the art from the above description. [Explanation of symbols]
