Description

[Detailed description of the invention] Industrial field of application: Recently, as the exterior, interior, equipment, etc. of buildings other than the original structure have become obsolete, there has been a need to remodel and repair them, and various new materials and remodeling methods have been proposed. There is. The present invention relates to a remodeling method for attaching a new window frame to the old window frame, leaving the old window frame made of iron as it is, without intervening auxiliary connecting members such as metal boards or angle pieces. All necessary work can be carried out inside the building without constructing or assembling work scaffolding on the outside of the building, causing less inconvenience to residents, and once completed, the exterior looks great and gives the appearance of a new window frame. be.

Problems to be solved by the conventional technology and invention: As the old iron window frames installed in the openings of buildings deteriorate and the formation of rust progresses, gaps are formed and the sealing function is lost, resulting in various inconveniences. There are known cases of replacing the window frames with new ones made of aluminum, but in that case, not only would it take a lot of effort to remove all the old window frames from the building structure, but the work would require residents to relocate. Scaffolding had to be constructed along the entire height outside the building and installation work had to be carried out from outside the building.

Figure 4 shows a longitudinal cross-sectional view of a horizontal rotating window that has been remodeled using the conventional remodeling method. 49 is the old iron window frame that remains fixed to the building body 50, and is made of aluminum. The new window frame 44 is the upper frame 4
5. It is assembled into a quadrilateral shape by the lower frame 46 and the left and right vertical frames. Since the remodeling method for the old window frame 49 is almost the same for the frames on all four sides, the lower frame of the new window frame 44 will be explained. A known insert 71 embedded in the concrete body through the old window frame 49 and shown as a dotted line and the angle piece 51 are fixed with screws 72, or
This angle piece 51 is fixed to the four peripheries of the indoor side outer circumference of the new window frame 44 by bolting or direct welding.
The new window frame 44 is fixed to the old window frame 49 by welding or bolting. At this time, the four circumferences of the connection between the new window frame 44 and the old window frame 49 must be shielded. Therefore, it is necessary to install an inner frame 53 on the indoor side and an outer frame 54 on the outdoor side as auxiliary members, but on the indoor side of the new window frame 44 and the old window frame 49, the vertical surfaces 46 and 56 are attached, respectively. On the other hand, angle-shaped support pieces 57 and 58 are fixed, and an inner frame 53 made of iron plate or aluminum and having a U-shaped cross section as shown in FIGS. 4 and 5 is attached to the outer periphery using screws 59, to shield. Next, the outer frame 54 is formed into a quadrilateral shape as shown in FIG.
The outer end edge 62 of the new window frame 44 and the bent edge 60 and the outer vertical surface 64 of the old window frame 49 and the bent edge 61 are fixed with screws 63 and 66, respectively. 65 is the latter connection fitting. The portion where the outer frame 54 joins the new window frame 44 and the gap between the bent edge 61 at the outer peripheral end and the wall surface 67 of the building body 51 had to be sealed from rain by applying seals 68 and 69 on the four peripheries, respectively. .

As mentioned above, the method of attaching a new window frame to an old window frame is troublesome, and requires setting up scaffolding on the outdoor side for installation work.
These auxiliary members required the interposition of metal substrates and auxiliary members for connection, and these auxiliary members had the disadvantage of reducing the opening area of the new window frame and, therefore, reducing the glass area of the shoji.

Means for solving the problem: The new window frame developed for the remodeling method of the present invention has a flat part facing the old window frame on the indoor side, and a hollow part connected to the outdoor side that is similar to the old window frame. Opposed to the front surface of the window frame facing outdoors, it is protruded laterally from the outer end of the hollow part to form a picture frame, and the surface of this new window frame matches the position of the diagonal line of the old window frame opening quadrangle. After inserting and passing it through the opening of the old window frame, it is rotated and held so that the flat part and the hollow part respectively take the above mounting positions, and the flat part and the old window frame are A spacer piece is inserted between the two to join them. Furthermore, the gap between the outer peripheral end surface of the frame and the building's exterior wall is filled and closed with a sealing material from the indoor side through the new window frame opening.

Example: An example will be described based on the drawings. 1 and 2 are a longitudinal sectional view and a horizontal sectional view, respectively, of a state in which a new window frame 1 is attached and an old window frame 3 is remodeled, and
The rotating shoji 2 installed after the new window frame was installed is shown with a two-dot chain line. The new window frame 1 includes an upper frame 4, a lower frame 5, left and right vertical frames 6, as shown in the partially cutaway external perspective view of FIG.
7, it is formed into a quadrilateral shape similar to a conventional window frame. The hollow parts 12, 13, 14, 15 of the outer part forming one half of the new window frame 1 protrude to the side of the outer end in a brim shape to form hollow frame parts 16, 17, 18, 19, and this part is the mounting position. Old window frame outdoor front 37
to face. The indoor side forming the other half has flat parts 20, 21, 22 facing the old window frame.
form 23. To install the new window frame 1 having such a shape, hold the new window frame 1 at a diagonal line formed by the quadrilateral of the opening of the old window frame 3, and hold the surface of the new window frame 1 at an angle, facing from the indoor side to the outdoor side. The frame portions 16, 17, 18, and 19 face the front surface 37 of the old window frame, and the flat portions 20, 21, 22, and 23 completely face the projection of the old window frame 3. The spacer pieces 33, 34, 35, and 36 are used to adjust the distance. After completing the positioning, inserts 43 were placed behind each prospective surface.
The new window frame 1 is fixed by screwing screws or bolts 38 through the flat portions 20, 21, 22, and 23.
By attaching the rear door contact member 24 to the lower frame of the new window frame, airtightness with the rotating shoji is maintained and the screw heads 38a in the lower frame are hidden. Next, sealing material 40 is applied to the four circumferential gaps 40 between the outer peripheral end surfaces 16a, 17a, 18a, 19a of each frame portion and the building body 42.
Reach out from the opening of the new window frame 1 and fill it.

Functions and Effects: (1) Even though the new window frame has an integrated frame that projects laterally, the new window frame is inserted diagonally from the indoor side at the quadrilateral diagonal position of the old window frame opening. This can be rotated and returned to the mounting position and fixed to the old window frame, and the gap around the frame is filled with the sealing material from the indoor side through the new window frame opening, so all work is done indoors. Therefore, the construction of troublesome outdoor scaffolding is completely unnecessary.

(2) There is no need to attach auxiliary connecting members such as metal boards and angle pieces to the new and old window frames, which is required in conventional remodeling methods, and only one external seal is required on all four sides.

(3) There is no need for on-site installation processing, such as cutting of parts, welding work, or fine adjustment for installing the inner or outer frame.

(4) Since the installation work is easy, it does not damage indoor furniture, interior decoration, etc., and does not cause any inconvenience to residents.

(5) The opening area of the new window frame, which is connected only with the spacer pieces for adjusting the distance, can be made larger than that of the conventional remodeling method because there is no attachment structure for the auxiliary connecting member as described above.

(6) There is no sign from the exterior that a new window frame was attached to the old window frame, and after completion, it appears that the old window frame was removed and the window frame was completely new.

(7) The outer frame is formed at the same time as the new window frame is installed, making the work simpler and more efficient.
