Description

The present invention relates to a panel fall prevention device and a panel construction device including the same.

Panels may be used for the interior or exterior of a building. As building panels, in recent years, metal sandwich heat insulating panels in which a core material made of heat insulating material is sandwiched between metal plates such as steel plates have become widespread, and in particular, outer wall materials, inner wall materials or partitions of large freezing / refrigerating warehouses and factory buildings have become widespread. Demand is increasing.

When building a building using this type of panel a lot, from the viewpoint of reducing the number of panels to save energy, the size is, for example, 10 m or more in length and 300 mm in maximum thickness. There is a tendency to use a panel, and the weight of the panel becomes as heavy as about 300 kg. For this reason, the panel installation work at the construction site is not easy to install with conventional manual work, and it is dangerous and costly. Therefore, for example, an erection lifter such as a winch or a crane is used. The panels are transported and installed. Further, there has been proposed a construction jig in which a panel in a horizontal state is raised, sucked and held by a suction pad by vacuum suction, transported by a forklift, and installed at a predetermined position (Patent Document 1).

When sucking and holding the panel 1, the suction pad 23 is aligned with one side of the panel 1 by the handle 26, then the vacuum pump is operated, and the panel lifter 2 is suspended to hold the panel 1 in an upright state. Is transported and installed.

[2-2] Panel fall prevention device The panel fall prevention device 3 is fixed to the arm portion 21a of the frame 21 in the panel lifter 2 as shown in FIG. In this case, two panel fall prevention devices 3 are provided on each arm portion 21a at diagonal positions in a total of two pairs on the left and right, and therefore these panel fall prevention devices 3 are arranged on the side of the panel 1. To. The panel fall prevention device 3 of FIGS. 3 and 4 is shown attached to the lower right arm portion 21a in FIG.

As shown in FIGS. 3 and 4, the panel fall prevention device 3 has a fixing portion 31 that is detachably attached to the arm portion 21a, and the tip of the fixing portion 31 is interposed via a biaxial joint member 33. The swing arm 40 is rotatably supported.

The fixing portion 31 is, for example, an angle material, has a certain length adjusted to the arm portion 21a, and is fixed with a bolt (not shown). The fixing portion 31 can be fixed by adjusting the protruding length from the arm portion 21a, whereby it can correspond to the width of the panel 1. A joint member 33 is supported at the tip of the fixing portion 31 via brackets 32a and 32b. The joint member 33 has two axes, a Z axis 34 extending in the vertical direction (vertical direction) of the panel 1 and an X axis 35 extending in the horizontal direction, with respect to the panel 1 held upright on the panel lifter 2. Have.

The swing arm 40 can rotate substantially horizontally about the Z axis 34 and tilt about the X axis 35. The swing arm 40 has an L shape, the base end portion 41a is supported by the joint member 33, and the panel holding portion 42 is provided on the inner surface of the bent tip portion 41b. The panel holding portion 42 has a structure in which a flat plate-shaped elastic pad 43 made of rubber or the like is fixed to a receiving plate 44, and the receiving plate 44 is supported by a plurality of bolts 45. A leaf spring (pressing means) 46 is interposed between the inner surface of the tip portion 41b of the swing arm 40 and the receiving plate 44, and the elastic pad 43 is separated from the inner surface of the tip portion 41b together with the receiving plate 44 by the leaf spring 46. Is being urged to.

Further, as shown in FIG. 5, two bolts 47 supported by the joint member 33 penetrate through the base end portion 41a of the swing arm 40, and the nut 48 screwed into the tip end portion of these bolts 47 A coil spring (biasing means) 49 is fitted between the base end portion 41a and the base end portion 41a in a compressed state. The swing arm 40 is urged by these coil springs 49 so that the angular position around the X-axis 35 is held at a fixed position. That is, as shown in FIG. 5, the swing arm 40 can tilt about the X-axis 35 against the urging force of the coil spring 49, and when the tilting force is released, the swing arm 40 returns to the original state by the coil spring 49. The original state is a state in which the elastic pad 43 faces the panel 1 in parallel and is in close contact with the panel 1 at the set position of the swing arm 40 as described later.

As shown in FIG. 4, the swing arm 40 has a standby position (FIG. 4: shown in FIG. 4: A) on the suction surface 1a side of the panel 1 on which the suction pad 23 is sucked, and a panel holding portion 42, with the Z axis 34 as the axis. The surface of the elastic pad 43 can be swiveled so as to be positioned at two positions, that is, the set position (shown in FIG. 4: B) in which the surface of the elastic pad 43 faces the back surface 1b on the opposite side of the panel 1 in parallel and is in close contact with the back surface 1b. ing. The swing arm 40 rotates substantially horizontally on the side of the panel 1, and at the set position, the elastic pad 43 presses the back surface 1b of the panel 1 by the leaf spring 46. The swing arm 40 is swiveled manually, and the swivel is regulated at the standby position and the set position by a locking means (not shown). As the locking means, for example, a type that can switch between locking and unlocking with one touch using a spring and a pin is preferable.

[3] Action of the panel fall prevention device and its effects The panel fall prevention device 3 of the present embodiment is normally held in the standby position. Then, after the panel 1 is held in the upright state by the panel lifter 2, the swing arm 40 is swiveled from the standby position to the set position. When the swing arm 40 is locked at the set position, the elastic pad 43 faces parallel to the back surface 1b of the panel 1 as shown in FIG. 5A, and the elastic pad 43 is placed on the back surface of the panel 1 by the leaf spring 46. It is pressed by 1b and comes into close contact.

In this state, the panel 1 is transported to the construction position by moving the panel lifter 2 using, for example, a crane or a forklift as described above, and the panel 1 is installed at a predetermined position by operating the handle 26 of the panel lifter 2. .. When the panel 1 is installed, the swing arm 40 is returned to the standby position, and the suction pad 23 releases the suction holding of the panel 1.

By the way, when the suction pad 23 of the panel lifter 2 sucks and holds the panel 1, if a situation occurs such that the vacuum is released or the vacuum operation is stopped for some reason, the panel 1 is held by the suction pad 23. It disappears and falls due to gravity. However, even if the suction pad 23 is in a vacuum down state in this way, in the present embodiment, the panel fall prevention device 3 prevents the panel 1 from falling.

That is, when the panel 1 falls, the swing arm 40 tilts downward with respect to the X-axis 35 as shown in FIG. 5B. The tilting of the swing arm 40 occurs when the back surface 1b of the panel 1 comes into close contact with the elastic pad 43 and strong friction is generated. When the swing arm 40 is tilted in this way, the elastic pad 43 is elastically deformed so as to reduce its thickness, and the distance between the elastic pad 43 and the suction pad 23 is narrowed, and the panel 1 is formed between the elastic pad 43 and the suction pad 23. It is held in a state of being sandwiched between and. This prevents the panel 1 from falling.

The more the panel 1 is about to fall, the more the swing arm 40 tilts and approaches the panel 1, and the elastic pad 43 acts to strongly press the panel 1. Therefore, the amount of fall of the panel 1 is limited to several centimeters at most, and the fall is surely prevented. Although the elastic pad 43 of FIG. 5B is in a state of being inserted into the panel 1, the elastic pad 43 is actually the back surface 1b of the panel 1 in a situation where the panel 1 is prevented from falling. In particular, the lower end of the elastic pad 43 is strongly subjected to the gravity of the panel 1, and the friction generated thereby prevents the panel 1 from falling.

According to the panel fall prevention device 3 of the present embodiment, the panel 1 is prevented from falling and safety is ensured as described above. Further, since the swing arm 40 can be tilted to prevent the panel 1 from falling, the structure is simple and the cost does not increase significantly.

Further, the suction pad 23 does not suck the panel 1 in a state of preventing the fall, but is in strong contact with the panel 1. Therefore, when the vacuum operation of the suction pad 23 can be restored, when the vacuum operation is restarted, the panel 1 is sucked and held by the suction pad 23 again. Therefore, there is an advantage that the work does not stagnate after the restoration of the vacuum operation and no labor is required.

Further, since the swing arm 40 is urged by the coil spring 49 so that the elastic pad 43 faces the back surface 1b of the panel 1 in parallel and is in close contact with the elastic pad 43, the entire surface of the elastic pad 43 is on the back surface 1b of the panel 1. When the panel 1 is dropped, a large amount of friction is generated due to the close contact, and the panel 1 can be effectively prevented from falling. The length of the swing arm 40 is set according to the thickness of the panel 1, but the length may be variable so as to correspond to various panel thicknesses.

Further, since the panel fall prevention device 3 is detachably attached to the arm portion 21a of the panel lifter 2 with a bolt, the fixing portion 31 can be removed and fixed to another panel lifter or the like, and has versatility. ..

It should be noted that the above embodiment is merely an example that specifically expresses the present invention, and the present invention is not limited to the above embodiment. That is, the present invention is based on the matters described in the claims, and various configurations and aspects derived from the matters include the present invention.

The present invention is suitably used for transporting and installing a panel such as a wall panel.
