As shown in the figure, a hook portion 8 that is engaged with a lip wall 7 of the upper frame 1 is formed at the tip of the pull-out plate 4.

In order to pull out the upper frame 1 using this sash removal jig G in the above, first, the pair of pull-out plates 4, 4 are removed.
The hook portions 8, 8 of the upper frame 1 are engaged with the lip walls 7, 7 of the upper frame 1. Next, in this state, the distance between the pair of pull-out plates 4, 4 is maintained with the distance adjustment holding bolt 6.

Furthermore, the distance between the hook hook pin 5 and the pair of pull-out plates 4, 4 is regulated so that the pull-out plates 4, 4 are parallel to each other, and the pair of pull-out plates 4, 4 are attached to the hook pin 5 using fixing bolts 9, 9. stick.

Next, the locking bolts 10, 10 are screwed inward from the pull-out plates 4, 4 to prevent the hook 11 of the chain block D hooked on the hook hooking pin 5 from shaking.

In addition, the hook 11 at the lower end of the chain block D
For example, the locking piece 2 protruding from the auxiliary jig 17
Lock it at 6. The locking piece 26 extends through the auxiliary jig 17 and the basic support 2, and also serves to stop the auxiliary jig 17 from rotating.

Then, in this state, the chain block D is operated, and the upper frame 1 is pulled out from the building frame B to form a clearance between the building frame B and the upper frame 1.

In this way, when removing the existing sash C, which is vertically long, without using a particularly long support, the basic support is erected horizontally approximately in the middle of the longitudinal direction, and the auxiliary support is used for comparison. It can be removed with good work efficiency using a small-sized sash removal jig G.

Next, FIG. 2 shows another embodiment of the present invention.

In this embodiment, an existing sash A, which is framed in a substantially rectangular shape with a long width and is attached to an opening C of a building frame B, is to be removed.
