Description

[Detailed description of the invention] The present invention relates to a fenestration frame removal device.

Conventionally, when renovating a fenestration frame made of wood or iron to a new window frame made of aluminum, etc., the fenestration frame is removed from the building base using a tensioning method, and then the new window frame is buried in the building base. is taken away. To remove the fenestration frame using this tensioning means, use a chain block or the like as the tensioning means, tension the chain blocks on the upper and lower or left and right opposing frames nfi, and pull and remove the opposing frames from the building base at the same time. Or, place tension on the base of the frame you are trying to remove! l'l r Uma'' is installed, and with a chain block etc. installed in ``Uma'',
The frame was pulled and removed from the base.

Pull the opposing frames at the same time! iI! When removing υ.

There was a problem in that the frame with weaker adhesion to the base was pulled first, and the frame with stronger adhesion could not be removed. In addition, for those with a "horse", the structure for fixing the "horse" to the base is complicated, and moreover, the "horse" must be reset for each frame that is to be removed.
In addition to being troublesome to construct, there was a risk that the ``horse'' would fall from the building base together with the frame the moment the frame separated from the base, which was a safety problem.

Therefore, the present invention has been devised in view of the above problems, and has an extremely simple structure that allows the tensioning means to be firmly and securely held in a predetermined position within the window space, and that can be set in one go. To provide a fenestration frame removing device capable of removing all upper and lower, left and right frames. Therefore, the feature is that in an apparatus for removing a fenestration frame from a building base by a tensioning means, a support that crosses the window space along the pulling direction of the tensioning means is detachably fixed to the nail base side. At the same time, a tensioning means located within the window space is rotatably connected to the middle part of the column.

Hereinafter, embodiments of the wooden invention will be described in detail based on the drawings.

What is shown in Figure 1.2 is a first embodiment of the tree invention.
