Description

A hanging tool 33 consisting of 4 parts.

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a guide device for lifting and guiding a panel body during installation of a mullion-type curtain wall to a building frame.

[Conventional technology]

A mullion-type curtain wall is a building frame made of reinforcing steel, etc., with a frame body that has multiple rectangular frame parts made of mullions and cross members, and a panel body made of glass plates, aluminum plates, etc. is attached to the rectangular frame parts. It is.

The construction of this type of mullion-style curtain wall is
After the frame is attached to the building frame, the panel is generally lifted up by a crane or the like and transported to the rectangular frame for installation.

[Problem that the invention seeks to solve]

During the above-mentioned construction, when the panel body is lifted by a crane or the like, the panel body shakes, which is dangerous, and the panel body may collide with the frame body, causing damage to the panel body. In particular, if the panel body is a glass plate, even a slight collision with the frame will cause damage.

Therefore, the present applicant previously filed an application for a lifting guide jig for a panel body as Utility Model Application No. 1987-90730 (Japanese Utility Model Application No. 63-198747).

Such a lifting guide jig for a panel body has sliding elements facing each other on the rear left and right sides of a base frame, and arms equipped with engaging elements attached to the front left and right sides of the base frame so as to be rotatable left and right. The base frame can be raised and lowered by using the slider as a guide along the vertical groove of the existing curtain wall unit, and the engaging element of the arm can be fitted into the vertical groove of the uninstalled curtain wall unit to raise and lower the base frame. Since the curtain wall unit can be held, an uninstalled curtain wall unit can be lifted and guided along the existing curtain wall unit.

However, although the aforementioned panel body lifting guide jig is suitable for lifting and guiding a curtain wall unit of a unit type curtain wall, it is not suitable for lifting and guiding a panel body of a mullus type curtain wall such as a glass plate. It is difficult to hold the panel body with the arm engager, and the rigidity of the panel body becomes weak, so even if you hold the lower part of the panel body with the arm engager, the upper part of the panel body becomes unstable and it becomes difficult to lift it. It can sometimes tremble.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a panel body lifting guide device for a cubic curtain wall that can safely lift and transport a panel body to a rectangular frame portion without damaging the panel body.

[Means and actions for solving problems]

A slider to be inserted into the vertical groove of the mullion is attached to the back of the left and right vertical members that make up the frame, and an engager having a groove into which the vertical edge of the panel body fits is installed on the front of the left and right vertical members. The arm is attached so as to be rotatable left and right between the upright position and the tilted position, and a locking mechanism is provided to hold the arm in the upright position, and the frame body is moved by the slider while the panel body is held by the engager. It consists of a guide jig that can slide along the mullions, and a hanger equipped with a pair of left and right rollers and suction cups that rotate along the mullions. Can be lifted and transported up to the square frame.
