Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a jig for lifting and guiding a panel body such as a curtain wall unit constituting a unit curtain wall when the panel body is attached to a building frame.

[Conventional technology]

A unit curtain wall is a structure in which a curtain wall unit is attached to a building frame made of a steel frame, etc. To install the curtain wall unit, the curtain wall unit is hoisted up by a crane installed on the rooftop or on the ground, and transported to the installation location and removed from the building. It is generally attached to the building frame.

However, when lifting a curtain wall unit with a crane, the curtain wall unit swings and is dangerous, and the curtain wall unit to be installed may collide with an already installed curtain wall unit and damage the curtain wall unit. For example, as shown in Japanese Utility Model Application Laid-Open No. 60-26542, a lifting guide jig has been proposed which allows a curtain wall unit to be lifted without swinging.

That is, as shown in FIG. 12, a dog-shaped arm b with a slider a and a bracket d with a slider c are rotatably connected by a pin e, and the middle part of arm b and the bracket are By providing a locking mechanism f for engaging and disengaging the lower part of d and rotating arm b around pin e, one slider a and the other slider c can be positioned in the left-right direction as shown by the solid line. When lifting the curtain wall unit, the arm b and the bracket d are engaged and connected by the locking mechanism f, so that one slider a and the other slider can be moved. Shift the position of the slider c in the left-right direction, make one slider a slidable along the existing curtain wall unit, and engage the other slider c with the distal curtain wall unit. Then, lift the final curtain wall unit along the existing curtain wall unit and transport it to the predetermined installation position, then release the locking mechanism f and attach the bracket d.
is rotated around pin e to move and attach the curtain wall unit at the end to the building frame side.

[Problem that the invention attempts to solve]

In such a lifting guide jig, one slider a and the other slider c protrude toward the building frame, so it is necessary to form a guide groove that opens forward in the vertical member of the curtain wall unit. There is.

On the other hand, vertical grooves that open laterally are formed in the vertical members of a normal curtain wall unit.
No guide groove is formed that opens toward the front. In other words, vertical grooves that open laterally are generally formed in order to install a sealing material between adjacent curtain wall units on the left and right, or to guide a gondola for cleaning a building.

Therefore, although the above-mentioned lifting guide jig can be used for a special unit curtain wall that has a guide groove opened in front of a vertical member, such as a special unit curtain wall in which a blind is attached to the outside, it cannot be used normally. Not available for unit curtain walls.

In addition, this lifting guide jig has a structure in which the boat-shaped slider moves vertically while sliding in the groove of the curtain wall unit. If there is, the slider may get stuck in the joint of this curtain wall unit.
There was a risk that the lifting work of the curtain wall unit would be very dangerous due to breakage.

SUMMARY OF THE INVENTION Therefore, the present invention provides a lifting guide jig for a panel body that can safely and smoothly attach a panel body such as a normal unit curtain wall having longitudinal grooves opening laterally to a vertical member. With the goal.
