Description

[Detailed Description of the Invention] The present invention relates to a structure for fitting around windows in renovated buildings.

In renovated buildings where the exterior walls of existing buildings are covered with new exterior materials such as metal plates, the old window frames may be left intact and reused. If such old window frames are to remain, it is important to decide how to fit around the windows in terms of ease of renovation work, good appearance, and protection from rain.

As shown in Fig. 1, the conventional renovation method involves fixing an angle piece 2 to the outer wall 1 of an existing building with anchor bolts 3, welding a horizontal rim 4 to the angle piece 2, and attaching the horizontal rim 4 A vertical rim 5 was welded to the rims 4 and 5, and a new exterior material 6 made of a metal plate was screwed to these rims 4 and 5. The rest around the window is the draining frame 7a and the draining stand 7b on the outer wall 1.
are removed by cutting work to form a recess 8, and the new draining frame material 9a and the tip of the draining material 9b are inserted into the recess 8 through a bracket 10a or 10b fixed to the horizontal rim 4. It was attached.

That is, the conventional structure for closing windows in renovated buildings involves cutting work, which generates noise and dust pollution and requires a great deal of time to construct. Furthermore, since the outer end surface of the old window frame 11 appears to remain intact, the imbalance between the new exterior material 6 and the old window frame 11 becomes noticeable, which is not desirable in terms of appearance.

Therefore, the present invention was devised in view of the above-mentioned problems, and is a method for reducing the area around windows of renovated buildings, which satisfies the requirements of ease of renovation work, good appearance, and good rain protection. The purpose is to provide structure. Therefore, its characteristics are:
In a renovated building where the exterior wall of an existing building is covered with a new exterior material, the new drain frame material that makes up the other three sides of the window opening, excluding the bottom edge, covers the old drain frame. At the same time, one end edge thereof is connected to the outer end surface of the old window frame via an L-shaped attachment, and the other end edge is connected to the opening periphery of the new exterior material.

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

In FIGS. 2 and 3, 20 is the outer wall of an existing building, and the outer wall 20 consists of a concrete frame 21 at the center, mortar 22 around it, and tiles 23 as the outer wall material. A window opening 24 is provided in the outer wall 20, and a window frame 25 is attached to the opening 24. 26 is the upper frame body of the window frame 25, and the outer wall 2 outward from the outer end surface of the upper frame body 26
0 is considered to be the draining frame 27.

A new exterior material 28 is attached to the existing exterior wall 20 in order to renovate its exterior surface. That is, the angle piece 29 is fixed to the outer surface of the outer wall 20 with an anchor bolt 30, and the angle piece 2
9, the horizontal furring 31 is fixed by welding, and the stacking furring 3
1, a vertical furring 32 is fixed by welding, and these furring edges 3
1 and 32, a new exterior material 28 made of a metal plate is fixed with screws 33.

The new exterior material 28 is also provided with an opening 34 corresponding to the window opening 24. A new drainage frame material 35 is provided to close the space between the opening 34 of the new exterior material 28 and the outer end surface of the upper frame body 26 of the old window frame 25. This new drainage frame material 35 has one end connected to the opening 3 of the new exterior material 28.
4 with screws 33, and the joint portion is sealed with caulking material 36. The other end of the new draining frame material 35 is an attachment 37
The new draining material 35 is connected to the outer end surface of the upper frame body 26 through the above, and the new draining material 35 covers the entire surface of the old draining table 27.

As shown in FIG. 3, the attachment 37
is approximately L-shaped, with a pair of legs 3 on the sides of the L-shape.
8 are formed, the leg portions 38 are in contact with the outer end surface of the old upper frame body 25 and are fixed with screws 39, and a sealing material 40 is filled between the leg portions 38.
Edge of new draining frame material 35 and attachment 3
7 is fixed with screws 41. The joint portion is sealed with a caulking material 42.

It should be noted that such a subdued structure around the window is adopted on the other three sides of the window opening 24 except for the lower side.

According to the above-mentioned embodiment of the present invention, there is no need to carry out the work of cutting down the area around the window as in the past, so noise and dust pollution are not generated, and the work time can be shortened. Furthermore, since there is no need for a bracket for attaching the draining frame material as in the past, the number of parts and the installation time can be reduced. In addition, since the new drainage frame material 35 covers the outer end surface of the old window frame body 26, the old window frame body 26
Although 5 remains, it looks like a new product and is desirable in terms of appearance. This frame 26
Since the attachment 37 is interposed when the new drainage frame material 35 is connected to the new drain frame material 35, it is easier to shut off the rain compared to directly joining the outflow.

Note that the present invention is not limited to the above embodiments.

According to the present invention, during renovation work, noise and dust pollution are not generated, work time is shortened, the number of parts is reduced, costs are reduced, and the appearance is beautiful. It has great effects.
