Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a new product of aluminum sash and a tool suitable for remodeling work (cutting of the inner frame, outer frame, inner frame) of the aluminum sash product installed in the already constructed building from the aluminum sash. The present invention relates to a rail cutting tool for cutting and removing a protruding rail.
[0002]
[Prior art]
At present, there are two methods of construction to change the window glass with aluminum sashes of buildings, condominiums, etc. from conventional ones to soundproof glass and dripproof glass.
A Remove and discard all aluminum sashes from the window frame, and install a new aluminum sash containing soundproof and drip-proof glass.
B A method of cutting and improving rail-shaped metal such as an inner frame that is a part of the frame of an aluminum sash that is currently installed, and replacing only the frame that contains soundproof and drip-proof glass.
A costs a lot of money (workforce, work by variant job, safety measures).
B is inexpensive and safe, but has time issues. For example, to remove the rail-like inner frame of an aluminum sash, there is a rail-like inner frame between the rail-like outer frame and the rail-like inner frame, so use pliers or metal scissors because the width is narrow I can't do it, and I will cut it off with a chisel and a hammer. In this work, it takes 5 hours or more to cut about 3 meters, and the work efficiency is very bad. Also, dust and noise are generated.
[0003]
[Problems to be solved by the invention]
The tool of the present invention solves such a problem in the case of replacing the currently used window glass with a soundproof and dripproof glass by the method B which is inexpensive, and makes it easier to make aluminum in a narrow place in a shorter time. This is a tool suitable for cutting and removing the joint portion from the lower portion of the metal rail portion whose cross section is processed into a convex shape such as a sash inner frame, outer frame, and inner frame.
[0004]
[Means for Solving the Problems]
A first characteristic configuration of the present invention is a rail cutting tool for cutting and removing a rail protruding from an aluminum sash,
A pair of rod-shaped bodies that can be brought into contact with both side surfaces of the rail with the rail interposed therebetween are projected from one side of the block in a state of being arranged at intervals, and the pair of rod-shaped bodies are arranged in the direction in which the pair of rod-shaped bodies are arranged. A rail extending in the aluminum sash is provided by providing a handle extending along the other side of the block and rotating the handle in the horizontal direction of the rail while the rail is sandwiched between the pair of rod-shaped bodies. This is because the part can be cut.
According to a second characteristic configuration of the present invention, the handle is attached to the block by a screw type, and is configured so as to be divided in the longitudinal direction and connectable to each other.
A third characteristic configuration of the present invention is that a plastic plate is attached to a side surface of the block facing the rail.

DETAILED DESCRIPTION OF THE INVENTION
Since the present invention has the structure as described above, when this is used, as shown in FIG. 2, an aluminum sash frame having a convex shape and a rail-like shape to be cut between two cylindrical rod- like bodies 2 is used. When the upper part of 7 etc. is sandwiched, and the handle is moved to the left and right by about 30 degrees, the joint part is cut by 2 centimeters, which is burnt at a time by lever application. By repeating this method, it is possible to easily cut the joint portion from the lower portion of the upper portion 7 of the metal rail portion having a rail shape and a convex cross section.
[0006]
【Example】
The usage of the tool of the present invention in the following three examples is the same, but the shape will be described in detail.
First embodiment: When the upper portion 7 of the rail portion such as a rail-shaped ordinary aluminum sash having a convex cross section is cut from the lower portion (a) The lower portion of the block 1 of the steel rectangular parallelepiped is about 25 mm. At two intervals, two holes are opened, and a cylindrical stainless steel rod 2 is attached.
(B) A hole for fixing the rod-like body 2 is formed in the front and rear portions of the block 1 and a set bolt 4 is attached. This can be removed.
(C) Attach a steel cylindrical handle 3 to the side of the block of a with a screw. To prevent slipping on the handle, a mesh notch is used to prevent slipping.
(D) A plastic plate 5 is attached to the lower surface of the block 1 to prevent scratches.
Second embodiment: When cutting thick and difficult to cut materials or when the sash is wide and the handle is difficult to operate By connecting three lightweight aluminum handles to the first example with a screw type , Use the one that makes it easy to cut by increasing and decreasing the pressure of the lever.
Third embodiment: When the shape of the rail of the aluminum sash is different, such as a T-shaped cross-section, and a cylindrical rod-shaped body cannot be used. Is attached so that the rail of the aluminum sash having a T-shaped cross section and the rod-like body come into close contact with each other without a gap. By operating the handle to the left and right by that, the joint part of the rail of the T-shaped aluminum sash with the application of lever is cut,
[0007]
[Effect of the present invention]
When cutting with this cutting tool, there is almost no dust and noise, and it takes about 20 minutes for 3 meters to remove the aluminum sash rail such as the inner frame, so the work efficiency is very good. Furthermore, since the tool itself is lightweight, it is easy to work and convenient to carry. Therefore, when the window glass is changed to a soundproof and drip-proof glass, it can be made inexpensively and in a short time.
