Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for removing a sash frame attached to a sash frame attachment opening in a building wall.

To replace an existing obsolete sash that is attached to a building's mounting wall with a new sash, remove the old sash frame from which the blinds, shoji, etc. of the existing obsolete sash have been removed from the mounting wall, and
After that, a new sash frame was installed, and blinds, shoji screens, etc. were installed.

The method of removing the old sash frame from the mounting wall is as shown in Japanese Utility Model Application Publication No. 56-124136, by pulling the upper and lower frames in the in-plane direction and removing them. There is a method in which the upper and lower parts are bent inward and partially removed, and the left and right short frames are sequentially removed using a special pulling tool from the vertically bent left and right parts and removed. It has been done.

However, with this removal method, when removing the left and right short frames, the upper and lower frames become tension parts and get in the way of removing the left and right vertical frames. The problem is that it is difficult to remove the top.

In addition, it requires not only a device for pulling the upper and lower frames, but also a special pulling tool for pulling up the left and right short frames.

The present invention was developed in view of the above circumstances, and its purpose is to provide a method for removing a sash frame in which the upper and lower frames and the left and right short frames can be easily removed with a small tensile force. It's about doing.

The present invention will be described in detail below with reference to the drawings.

In the sash frame mounting opening A' of the mounting wall A, there is a sash frame E that is formed by framing the lower frame B, the upper frame C, and the left and right short frames D-D into a rectangular shape.
is attached to this sash frame E, and sashes, shoji, etc. are attached to this sash frame E to create a sash.

To remove and remove this satsushi frame E, first
Remove the shoji, etc., pull the lower frame B and upper frame C in the direction inward of the sash frame plane, and as shown in Fig. 2, attach the lower frame B and the upper frame C to the sash frame mounting opening A' of the mounting wall A. At the same time, pull out the upper and lower end parts (A) and (A) that connect with the upper and lower frames C-B of the left and right short frames to lift them up from the mounting wall A, and partially remove them from the mounting wall A. Remove.

After that, the upper frame C and the lower frame B are removed by cutting the upper and lower end portions (a) and (a) of the left and right short frames DD which have been lifted up and removed from the mounting wall A, and the intermediate portions thereof are removed.

(b) is the cutting position.

Then, as shown in Fig. 3, the upper and lower parts (Iy, (Iy)
is used as a hook or clamping part of the removal device, and is pulled inward in the plane of the sash frame to remove the intermediate portion (c) of the left and right short frames from the mounting wall A.

In addition, in order to pull and remove the lower frame B of the sash frame E in the in-plane direction of the sash frame, as shown in FIG. , are provided so as to be slidable in the longitudinal direction and can be locked and fixed at any arbitrary position of the support arm 1, and a cable winder 11 serving as a tensioning device is attached to the support arm 2 via a mounting cable 10, The cable winding machine I+ has a structure in which the cable 13 can be wound up by swinging the handle 12, and the cable 13 can be manually unwound by any means. It may be pulled using a removal device connected to the hook 15.

In other words, the upper and lower chambers have one longitudinal end surface 1a of the column 1 in contact with the floor surface A1, and the upper and lower parts of the outdoor side surface 1b are connected to the sash frame mounting opening of the mounting wall A, and are continuous with the upper and lower walls. The hooks 3 are brought into contact with the upper end surface of the lower frame attachment part (that is, the lower wall part) A(K''3), and the pair of hooks 15 and 15 are attached to the lower frame B. to lock.

In this state, when the handle 12 is swung to wind up the cable 13 with the cable winder 11, the lower frame B is pulled upward via the hooks 15 and 15 and pulled out from the lower wall At.

At this time, the reaction force of the lower frame pulling force is supported by the floor surface A and the upper end surface of the lower frame mounting part (that is, the lower wall part) A (through the one end surface 1a of the support and the latch 3), and A falling moment (Ml) acting toward the outdoor side acts on the column 1 using the abutting part between the latch 3 and the child at the upper end of the lower frame attachment part as a fulcrum, so that the upper part of the outdoor side surface 1b of the column 1 is on the mounting wall A. The support column 1 does not fall down toward the indoor side due to being pressed against the upper indoor wall A2.

Therefore, the lower frame B can be reliably pulled out.

When removing the upper frame C by pulling it in the in-plane direction of the sash frame, turn the column 1 upside down and remove the one end surface 1 of the column 1 as shown in FIG.
a to the ceiling A4 of the mounting wall A; 1-1; latching 3;
The upper and lower sides of the 0 room side surface 1b are attached to the upper and lower room side walls A2 of the mounting wall body A.
When it comes into contact with A5, the pair of hooks 15 and 15 are locked to the upper frame C, and the cable winder 11 winds up the cable 13, thereby pulling the upper frame C in the in-plane direction of the sash frame. It can be stretched and removed.

At this time, the reaction force of the upper frame pulling force is supported by the ceiling A4 and the upper frame mounting lower end surface A2 via the one end surface 1a of the column and the latching member 3, and the latching member 3 and the upper frame are attached to the column 1. Since the overturning moment (M2) which moves toward the outdoor side with the abutting part with the lower end surface of the mounting as a fulcrum acts, the lower indoor outer side surface 1b of the column 1 is pressed against the lower indoor wall of the mounting wall A, causing the column 1 to move indoors. It won't fall inwards.

Therefore, the upper frame C can be reliably pulled out.

When removing the short frame by pulling it out, as shown in FIG. ) The left and right sides of the outdoor side surface 1b of the support column 1 are in contact with the left and right indoor side walls A6. , screw rod 15
c and 15c are screwed together, and the raised and remaining partial ridges 5 on the short frame are replaced with a pair of threaded rods 15c and 15.
By tightening c, the claws 15b and +5b are clamped and locked, and the thread winding machine 11 winds up the cable 13, thereby pulling out and removing the intermediate part (c) of the short frame from the mounting wall A. can.

At this time, the reaction force of the pull-out force of the short frame is supported by the vertical wall of the mounting wall A and the end surface layer on the side of the short frame attachment part via the one end surface 1a of the column and the latch 3, and the column 1 Since the overturning moment hIL& acting toward the outdoor side using the abutting part between the latch body 3 and the end surface of the short frame attachment part as a fulcrum acts on the support column 1, the right side of the outdoor side surface 1b of the column 1 is attached to the extension wall. The support column 1 does not fall down toward the inside of the room due to being pressed against the right ventricular wall of body A.

Therefore, the short frame can be reliably pulled out and removed.

As mentioned above, the sash frame can be pulled out (the part that supports the reaction force of the force can be supported at two places, the end face of the column 1 and the latch rest 3), or it can be supported by only one of the supporting parts. Even when supported, the frame can be pulled out.

According to the method for removing a sash frame according to the present invention, the upper and lower frames and the left and right short frames can be easily removed, and after the upper and lower frames are cut and removed, the left and right short frames are pulled out and removed. Since it does not act as a tension member, it is possible to pull out and remove short left and right frames with a small tensile force, making it extremely easy and efficient to remove the left and right vertical frames. Since the concrete is cut at the upper and lower end portions, the mounting wall body does not get bent or cut together with the concrete during the cutting work, and can be easily and quickly cut.

In addition, the left and right short frames can be pulled by using the ends that rise above the mounting wall surface, so the left and right short frames have no hooks and have a shape that is difficult to grab. too,
In addition, the special hook can be easily and reliably pulled and removed without any troublesome machining such as holes or recesses.
