Description

[Detailed Description of the Invention] The present invention relates to an ALC panel lifting fitting that can stably and quickly lift an ALC panel used in an exterior wall lateral wall construction method using bolts.

When using ALC (autocube cured lightweight aerated concrete) panels, which have excellent heat insulation and fire resistance, as the exterior walls of factories, warehouses, etc., the exterior wall horizontal wall construction method is generally used.

As shown in Figure 1, which shows the concept of this exterior wall horizontal wall construction method using the bolt fastening method, bolt through holes 2 are drilled at both ends in the width direction of the ALC panel 1, through which bolts (not shown) are passed. ALC via the bolt inserted into bolt through hole 2
The panel 1 is attached to a support member 3 such as a pillar or a beam so that its longitudinal direction is horizontal. When the building becomes high-rise, ALC panel 1
It is necessary to lift it to the construction site using a lifting device such as a crane, but in the past, slings were used.
Attach it to the center of the ALC panel 1, and use a sling to lift the ALC panel 1, or use a clamping jig such as a shiyako vise to attach the ALC panel 1.
A widely used method has been to fix the ALC panel 1 to a holder and lift the ALC panel 1 using the clamping jig.

However, the method using a sling has the drawback that it is extremely troublesome to attach and detach the sling to and from the ALC panel, and it is difficult to stably lift and lower the ALC panel 1 in a horizontal state. On the other hand, with the method of using a clamping jig, the clamping jig ends up protruding from the surface of the ALC panel, making it extremely difficult to hang the ALC panel in an extremely narrow work space. There was a risk that 1 would collide with scaffolding and be damaged.

Therefore, it has been considered to apply a hanging device as disclosed in Japanese Utility Model Publication No. 54-45400. This hanging tool uses a hanging rod and a holding claw 9 that is rotatable with respect to the hanging rod to clamp and hold the suspended object through spring force, and is able to handle changes in the thickness of the suspended object. It is designed to be compatible.

However, when removing the insertion pin protruding from the suspension rod from the bolt insertion hole formed in the suspended object, the holding claw 9 must be rotated by operating the handle against the spring force of the coil spring 7. Since it requires movement, there is a drawback that the workability of attaching and detaching the hanging equipment is not very good. Moreover, if the thickness of the suspended object changes, the suspended object will tilt as the center of gravity changes, resulting in poor stability and even danger when working at heights.

This invention focuses on the fact that the ALC panel used in the exterior wall side wall construction method has bolt holes at both ends in the longitudinal direction, and uses these bolt holes to
An object of the present invention is to provide an ALC panel hoisting fitting capable of stably, easily and quickly hoisting a panel even when the thickness of the panel changes.

The ALC panel lifting fitting of the present invention that achieves this purpose consists of a wire whose central part is connected to a lifting device and a shackle attached to each end, and a pair of wires which are pre-drilled at both ends in the width direction of the ALC panel. Hook pins that are removably inserted into the respective bolt holes are provided protruding from the lower end, and shoulder portions that can come into contact with the upper end surface of the ALC panel are formed at the upper part, and the upper end is connected to the shaft. a first clamping plate rotatably connected to each other via a pin; and the ALC.
They sandwich the panel and face each of the first clamping plates, and their upper ends are rotatably suspended from the pins, and the shoulder portions of the first clamping plates in the thickness direction of the ALC panel. a second clamping plate each having a shoulder portion having a size corresponding to the size, and a second clamping plate each having a shoulder portion formed on the upper part thereof, and a second clamping plate that is detachably attached to the pin, and the first clamping plate is arranged at an interval corresponding to the thickness of the ALC panel. It is provided with a spacer that can adjust the distance between the plate and the second sandwiching plate.

Hereinafter, an embodiment of the ALC panel lifting fitting according to the present invention will be described in detail with reference to FIGS. 2 to 4.

As shown in FIG. 2 showing the external appearance of this embodiment, FIG. 3 showing its cross-sectional structure, and FIG. 15 are connected, and these shafts 15 have ALC
A pair of sandwiching plates 1 facing each other with the panel 11 in between
2 and 13 are connected to each other via a bolt 16 and a nut 17 screwed into the bolt 16, respectively. Spacers 18a, 18b, and 18c are interposed between these, and the central spacer 18a, shackle 15, etc. sandwiched between the sandwiching plates 12 and 13 are connected to the ALC panel 11.
It is converted into various sizes depending on the plate thickness.
The clamping plates 12, 13 and the shackle 15 are bolts 1
6, and normally one of the clamping plates 12 hangs down from the bolt 16 due to its own weight. At the lower end of the other clamping plate 13, which is set longer than the one clamping plate 12, there is a bolt hole that protrudes toward the one clamping plate 12 and is pre-drilled in the ALC panel 11. A hook pin 20 that can be fitted and locked into the hole 19
is installed protrudingly. Note that the distance between the sandwiching plates 12 and 13 may be appropriately set using spacers 18a, etc., depending on the thickness of the ALC panel 11, but the protruding length of the hook pin 20 may be set as appropriate depending on the thickness of the ALC panel 11. If the plate 12 is shorter than the other clamping plate 13 and there is no risk that the tip of the hooking pin 20 will hit one of the clamping plates 12, it can be set freely.
Further, shoulder portions 21 and 22 bent in the thickness direction of the ALC panel 11 are formed on the upper portions of these sandwiching plates 12 and 13, respectively.
The dimensions of the ALC panel 11 along the thickness direction are set to be equal, and the center of the thickness of the ALC panel 11 is always located between the shoulders 21 and 22 to ensure stable suspension. . Note that when the clamping plate 13 rotates around the hook pin 20 during suspension, the shoulder portion 21,
It is desirable that the height from the hooking pin 20 to the shoulders 21, 22 is not much larger than the height from the bolt through hole 19 to the upper end surface of the ALC panel 11 so that the bolts 22 come into contact with each other.

In the exterior wall side wall construction method, in order to stack the ALC panels 11 horizontally, a set of lifting fittings as described above is prepared, and the shackle 15 of each lifting fitting is connected to both ends of the wire 14. As shown in Figure 4 a to c showing the procedure of this lifting work, first,
After raising ALC panel 11 vertically (4th
(see Figure a), rotate one of the clamping plates 12 horizontally about the bolt 16 relative to the other clamping plate 13, and hook the other clamping plate 13 into the bolt through hole 19 of the ALC panel 11. Insert pin 20 (4th
(see figure b). Next, when you release your hand from one of the clamping plates 12, the clamping plate 12 rotates under its own weight and returns to its original state (see Fig. 4c), and automatically locks the ALC panel 1.
1 is held by the sandwiching plates 12 and 13.

After that, when the ALC panel 11 is lifted by driving a lifting device (not shown) via the wire 14,
As the clamping plate 13 rotates around the hook pin 20, its shoulder 22 is pressed against the upper end surface of the ALC panel 11, and the ALC panel 11 is clamped from above and below by the hook pin 20 and shoulder 22. It becomes a state of being absorbed. Furthermore, the plane containing the wire 14 almost coincides with the plane containing the center of gravity of the ALC panel 11,
The ALC panel 11 can be stably placed on the ALC panels 11 already stacked in a vertical state. In addition, when removing the lifting bracket from the ALC panel 11, use one of the clamping plates 1.
2 to the side and pull out the hook pin 20 from the bolt hole 19.

As described above, according to the ALC panel lifting fitting of the present invention, simply by inserting the hook pin protruding from one of the clamping plates into the bolt hole, the other clamping plate will hang under its own weight, so the ALC panel can be hung between these two clamping plates. It is now possible to hold the ALC panel with a pair of clamping plates, making it possible to attach and detach the lifting fittings to and from the ALC panel extremely quickly.Moreover, the ALC panel is clamped from above and below between the hooking pin and the shoulder. This allows the ALC panel to be transported stably without tilting. Furthermore, during transportation, the amount of protrusion from the surface of the ALC panel is small, making it possible to work safely even in a narrow work space.
