Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a panel hoisting method in which the edge of a flat plate of a panel is removably fitted in, the roof panel, etc. can be easily hoisted, and the dangers associated with the removal work can be prevented. Regarding metal fittings.

[Background technology]

In buildings using the panel construction method, the roof body is also formed using panels, but in order to lift such panels, lifting fittings such as hooks have traditionally been used, and the panels are lifted and placed on the frame. In addition to requiring time and effort to remove the lifting fittings from the panel in its current condition,
In particular, it is dangerous to remove the hooks that lock the eaves.

[Purpose of the invention]

The present invention provides a panel lifting metal fitting that can solve the above-mentioned problems by providing a base into which the edge of the panel is removably inserted, making it easier to lift the panel, and to make it easier to remove the panel. An embodiment of the present invention will be described below based on the drawings.

[Disclosure of the invention]

Embodiment In the figure, a panel lifting fitting (hereinafter referred to as fitting) 1 of the present invention has a base 2 into which a panel P can be detachably fitted, and hanging pieces 4, 4 into which a reinforcing material 3 of the panel P is loosely fitted. It is set up.

The panel P has a right triangular shape, for example, and has a second
Rafters, that is, reinforcing materials 3 are attached by nailing, etc., parallel to the long side 9 to the lower surface of the flat plate 6, which in this example is a roofing board, which is arranged with its oblique side 7 touching the ridge of the hipped roof illustrated in the figure. They are arranged separately, and by placing them on the roof frame body A as described above, a roof base can be formed. The flat plate 6 of the panel P is provided with through holes 11, 12, 13 in a triangular arrangement with the upper end located at the middle part of the oblique side 7, and opening at the side surface of the reinforcing material 3. A locking piece 15 that faces the upper part through the through holes 11, 12, and 13 is formed in the. The locking piece 15 is formed using a bolt that passes through the reinforcing member 3 horizontally and has a protruding head and is fastened with a nut.

The metal fitting 1 has a substantially U-shaped base 2 with an upper piece 20 and a lower piece 21 formed at right angles above and below a back piece 19 whose height exceeds the thickness of the flat plate 6. The edge of the flat plate 6 can be detachably inserted between the lower piece 2.
1 is provided with a notch 23 at its center, which has a width equal to or greater than the width of the reinforcing material 3 and reaches deep into the inner part of the reinforcing material 3. The lowering piece 4 is provided at the lower end to which the bottom piece 24 can be inserted and loosely fitted with a gap between the sides thereof. In addition, the back part of the hanging piece 4 extends and closes the said back piece 19. Further, the length between the upper surfaces of the lower piece 21 and the bottom piece 24 is formed to be slightly smaller than the height of the reinforcing member 3, so that the bottom piece 24 of the metal fitting 1 supports the lower surface of the reinforcing member 3. At the same time, by being supported by the bottom piece 24, the flat plate 6 rises above the upper surface of the lower piece 21. Further, on the upper piece 20, there is a hanging bolt 25 having a ring-shaped head to which a lifting rope or the like can be connected.
is installed.

Operation: The metal fitting 1 of the present invention is connected to a hanging ring 29 at the tip of a lifting rope 28 of a crane vehicle 27 or the like via a bar 31 with a hanging bolt 25, and
The hanging ring 29 includes a rope 33 having a hook 32 passing through the through hole 11 and a rope 33 having a hook 32 passing through the through holes 12 and 13.
4, 34 at both ends, a rope 37 is connected with a spring 36 interposed therebetween, and the roof panel P locks the hooks 32, 34, 34 to the locking pieces 15, respectively, By fitting 1 approximately in the center of the short side 10 of the panel P that will serve as the eave stand, as described above, the panel P has an inclination approximately equal to the roof slope so that the short side 10 is in the lower position. hang. Furthermore, after placing it on the roof frame structure A,
By further relaxing the lifting rope 28,
The weight applies an outward force to the metal fitting 1 through the bar 31, and the metal fitting 1 can be removed smoothly and easily without requiring any human effort. To eliminate removal work and improve work safety and efficiency. In addition, the reinforcing material 3 is fitted loosely between the vertical pieces 4 to prevent it from sliding laterally, and the bottom piece 24 supports the lower surface of the reinforcing material 3, so that its weight acts on the flat plate 6. This makes lifting work safer.

〔Effect of the invention〕

In this way, the metal fittings of the present invention allow panels to be lifted up in a detachable manner, making the lifting work easier, and they can also be easily removed, eliminating the danger associated with removing the lifting metal fittings and improving work safety. . The metal fitting 1 of the present invention can be used for lifting not only triangular panels but also square panels, floor panels, wall panels, etc.
