Description

[Detailed description of the invention] (Field of industrial application) This invention allows the existing old window frame to remain without removing it from the window opening base of the building, and replaces the pre-framed new window frame with the old window frame. This invention relates to a device that fits into a window frame and attaches a new window frame to an old window frame.

(Prior art) When converting an old wooden or iron window frame to a new window frame such as an aluminum window frame for windows of various buildings, the concrete at the opening of the window frame of the building is removed by chisel work. Instead of removing the old window frame 2 and exposing the reinforcing bars, and using these reinforcing bars to attach the new window frame, the old window frame is left in place.
It is known that a window frame refurbishment method is practiced in which a new window frame that has been framed in advance is fitted into the old window frame and the new window frame is attached to the old window frame. At this time, since it is difficult to directly connect the new window frame to the old window frame, a method is used to attach a continuous fitting to the old window frame and connect an anchor fitting provided on the new window frame to this continuous fitting. is often used.

(Problem that Koso is trying to solve) In order to install the connecting fittings and the interior facing side of the new window frame without distortion, it is required that they be flush vertically. For this purpose, it is necessary to connect the anchor fittings while accurately positioning them horizontally with respect to the surface of the connecting fittings facing into the room.

In particular, because the space between old and new window frames is narrow, it is difficult to horizontally connect the anchor fittings with the connecting fittings, and if the connection cannot be made accurately and the work needs to be done again, it is a huge waste of effort. Therefore, it is desirable to be able to reliably position it horizontally in one operation. However, it has been difficult to satisfy such demands.

In view of the above, the present invention is designed to distort the internal frame by making the surfaces of the continuous fitting and the new window frame vertical and flush, even if the anchor fittings are not accurately horizontally connected to the continuous fitting. To provide a mounting device for old and new window frames that can efficiently perform mounting work without any trouble.

(Means for solving the problems) The technical measures taken by the present invention to solve the problems of the conventional technology are characterized by removing the existing old window frame from the window opening base of the building. This is a device that attaches the new window frame to the old window frame by fitting the new window frame, which has been framed in advance, into the old window frame without leaving any A continuous fitting is attached with a bolt, one end of the bolt protrudes between the opposing new and old window frames, and a mounting piece is provided on the continuous fitting, and the mounting piece is inserted from the rear end of the continuous fitting on the indoor side to the new window frame. A vertical plane extending toward the window frame,
and a horizontal plane extending from the extending end of the vertical plane toward the space between the old and new window frames and perpendicular to the vertical plane,
An alignment reinforcing plate is welded to this horizontal surface and one end of the bolt, and an anchor fitting is welded to this reinforcing plate in a cantilevered manner, and the new window frame is supported by this anchor fitting, and the new window frame is installed indoors. The surface facing the vertical surface and the rear end surface of the guide plate are flush with each other, and the interior frame on the indoor side is attached via these flush surfaces.

(Function) Since the anchor fitting is cantilever-supported with respect to the reinforcing plate, it can swing up and down. Therefore, even if the anchor fittings are not positioned accurately horizontally, the anchor fittings should be adjusted so that the indoor facing surface of the new window frame supported by the anchor fittings is flush with the vertical surface of the continuous fitting fittings facing indoors. Positioning can be done through rocking. At this time, the reinforcing plate welded to the horizontal plane extending from the vertical surface of the continuous fitting is welded to the continuous fitting mounting bolt, so that the perpendicularity of the vertical plane is firmly maintained, and the anchor fitting can be moved up and down. The vertical plane of the continuous fitting does not move easily even when it swings, and the vertical positioning of the indoor side of the new window frame can be accurately determined based on the vertical plane. As a result, it is possible to accurately and easily make the surfaces of the connecting fittings and the new window frame facing into the room vertical and flush with each other.

(Embodiment) The present invention will be described in detail with reference to the embodiment shown below. Fig. 1 is a front view of a renovated window frame as seen from the indoor side;
Fig. 2 is a sectional view taken along the line shown in Fig. 1 of the embodiment of the device of the present invention, Fig. 3 is a side view of essential parts of the alignment guide plate, Fig. 4 is an oblique view of the anchor fitting, and Fig. 5 is the internal frame. Figure 2 shows the upper frame of the existing old window frame, and 2 shows the window opening base of the building where the upper frame is installed. It shows. This example only partially shows the upper frame, but of course the old window frame includes not only the upper frame, but also the left and right side frames that connect to both ends of the upper frame.
Furthermore, the lower ends of the side frames are connected and the lower frame is parallel to the upper frame to form a rectangular or square frame. The structure and shape of the frame are slightly different, so when connecting the lower frame of the new window frame, a slightly different mounting structure is used for the upper frame, but the left and right side frame parts are The mounting structure is substantially the same as that of this upper frame portion, and the mounting device of the present invention is mainly applied to this upper frame and left and right side frame portions. In the present invention, first, a continuous fitting 3 having a substantially horizontal S-shape is attached to the lower surface of the upper frame (hereinafter referred to as the side frame) 2 via an elongated hole 3a and a fastening bolt 4. One end of this bolt 4 protrudes between the old and new window frames. A vertical surface 5a and a horizontal surface 5b are connected to the front end of the connecting fitting 3 facing outdoors on the left side in the figure.
A mounting piece 5 shaped like a letter is formed.

In addition, a mounting piece 6 is provided at the rear end of the connecting fitting 3 facing the interior of the room.
The window frame 10 has a vertical surface 6a extending from its rear end toward the new window frame, and a horizontal surface 6b extending from the extended end of the vertical surface 6a perpendicular to the vertical surface 6a toward the space between the old and new window frames, giving it an L-shape.

Then, loosely fit the elongated hole 3a of the metal fitting 3 into the fastening bolt 4 installed in the upper frame 1, and adjust it so that the vertical surface 5a of the mounting piece 5 at the front end thereof is locked to the front end of the upper frame 1. , washers 7, and nuts 8, the metal fitting 3 is fixed by the vertical surface 5a and the upper frame 1, and the fitting 3 can be positioned in the front-rear direction. At this time, the nut 8 and the fastening bolt 4 are fixed by welding 9 or the like to prevent fluctuation. After the continuous fitting 3 is attached to the upper frame 1 in this manner, a reinforcing plate 10 for alignment is attached to the horizontal surface 6b of the attachment piece 6 at the rear end and the fastening bolt 4.

That is, the rear end of the reinforcing plate 10 is attached to the mounting piece 6.
A part of the front end thereof is attached to one side of the end projecting downward from the bolt 4 nut 8, and fixed by welding 11, 12. The reinforcing plate 10 is installed horizontally, and the rear end 10c of the plate 10 is properly aligned with the vertical surface 6a of the mounting piece 6 for fixation. Note that this reinforcing plate 10 is a long plate body 10 as shown in the third figure.
Folds 10b for cutting are arranged in advance in a row for each fixed size on A, and used by breaking off from the folds 10b during on-site construction.

Next, on the lower surface of this reinforcing plate 10,
As shown in FIG.
Anchor metal fitting 13 formed in a rising shape is applied to b, one clamp claw piece 13b is fixed to the lower surface of plate 10 by welding 14, and anchor metal fitting 13 is attached to plate 10 in a cantilevered manner.

Then, the upper frame 15 of the new window frame, which has been framed in advance, is attached to the anchor fitting 13. That is, the upper frame 15 is formed with locking edges 15a, 15a that project horizontally inward at both ends in the front-rear direction at the top of the upper frame 15. Then, the new window frame is fitted into the old window frame, and the front and rear locking edges 15a, 15 of the new upper frame 15 are fitted.
b on the front and back of the anchor fitting 13.
The new upper frame 15 is attached to the anchor metal fitting 13 by inserting and clamping the upper frame 15 into the gap between the main surface 13b and the horizontal main surface 13a by moving the upper frame 15 forward and backward. When the attachment of the new upper frame 15 to the old upper frame 1 is completed in this manner, the inner and outer frame members are attached. At this time, the vertical rear end surface of the new upper frame 15 is the vertical surface 6a of the mounting piece 6 of the continuous joint fitting 3 that has been previously installed and fixed.
Adjust so that they are flush with each other. This adjustment is possible even if the anchor fitting 13 is not installed horizontally, since the anchor fitting 13 is cantilevered with respect to the reinforcing plate 10, it can swing up and down. This is achieved by making the indoor side surface of No. 15 flush with the vertical surface 6a thereof. Moreover, since the reinforcing plate 10 welded to the horizontal surface 6b extending from the vertical surface 6a is welded to the continuous joint fitting mounting bolt 4, the vertical rear of the vertical surface 6b is firmly held, so that the reinforcing plate 10 is welded to the horizontal surface 6b extending from the vertical surface 6a. The vertical positioning of the indoor side surface of the new upper frame 15 with respect to the surface 6b can be made accurate. As shown in the figure, the vertical mounting surface 16a of the frame mounting bracket 16 is brought into contact with the rear end surface of the continuous joint fitting 3 and the rear end surface of the new upper frame 15, which are aligned on the same vertical plane via the guide plate 10. ,
Fixing devices 1 such as screws are attached to the vertical surface 6a of the mounting piece 6 of the continuous joint fitting 3 and the rear end surface of the new upper frame 15, respectively.
