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 made of metal plates, etc., 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. Then, for the area around the window, the draining stand 7 of the outer wall 1 is removed by cutting work to form a recess 8, and a new draining material 9 is formed in the recess 8.
A new draining material 9 was attached via a bracket 10 fixed to the horizontal rim 4 so that the leading end of the draining material 9 could be inserted into the bracket 10.

In other words, 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. Furthermore, since the bracket 10 for attaching the new draining material 9 has a cantilevered structure, a reinforcing member 12 is required, which requires additional time and members for attachment, leading to an increase in cost.

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's window-covering structure in which the exterior wall of an existing building is covered with a new exterior material, the new draining material that forms the lower part of the window opening covers the old draining table, and its upper edge is similar to the old one. It is connected to the outer end surface of the lower frame of the window frame via an attachment, and the lower edge is connected to the lower peripheral edge of the opening 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, tiles 23 as the outer wall material, and the like. 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 lower frame body of the window frame 25, and the outer wall 2 outward from the outer end surface of the lower frame body 26
0 is a draining table 27 formed on an inclined surface.

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
A horizontal furring 31 is fixed to 9 by welding, and further the horizontal furring 31
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 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 lower frame 26 of the old window frame 25. This new draining material 35
is fixed at its lower end to the lower periphery of the opening 34 of the new exterior material 28 with a screw 33, and the joint is sealed with a caulking material 36. The upper end of the new draining material 35 is inserted through the attachment 37,
The new draining material 35 is connected to the outer end surface of the lower frame body 26 and covers the entire surface of the old draining table 27.

As shown in FIG. 3, the attachment 37 is approximately T-shaped, and has a pair of legs 38 on the sides of the T-shape.
are formed, the leg portions 38 are in contact with the outer end surface of the old lower frame body 25, and a sealing material 39 is provided between the leg portions 38.
is filled. The upper edge of the new draining material 35 and the attachment 37 are attached to the lower frame body 26 with screws 40.
are fastened together. The joint portion is sealed with caulking material 41.

According to the above-mentioned embodiment of the present invention, there is no need to carry out the work of removing 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 material as in the prior art, the number of parts and the installation time can be reduced. In addition, the new draining material 35 is the old window frame body 26.
Since the outer end surface of the window frame 25 is covered, it looks like a new window frame even though the old window frame 25 remains, and is desirable in terms of appearance. When connecting the lower frame body 26 and the new draining material 35, the attachment 37
Since the two are interposed, it is easier to shut off the rain compared to directly joining the two.

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

According to this invention, during renovation work, noise and dust pollution will not be generated, work time will be shortened, the number of parts will be reduced, costs will be reduced, and the appearance will be cleaner. It is effective.
