Description

[Detailed Description of the Invention] The present invention relates to an improvement device for renovating old exterior wall materials displayed in existing buildings into new exterior wall materials.

If old exterior wall materials are removed from the building frame and new exterior wall materials are placed on top of them, it would be undesirable in terms of the number of days required for the removal work and the generation of dust. There have been examples of construction in which new exterior wall materials are placed over the remaining walls without removing them. In this case, the old exterior wall material is left as is, and the new exterior wall material is spread over it via the support frame, so naturally the new exterior wall material protrudes more toward the outside, and this causes Since the difference in level between the existing old window frame and the new exterior wall material becomes large and the appearance becomes unsightly, it becomes necessary to remove the old window frame or separately install a new window frame close to the new exterior wall material. However, existing old window frames are attached directly to the building frame, so there is no problem in terms of strength, but new window frames are installed in a position that protrudes outward from the building frame, so the supporting structure must be sufficiently strong. New window frames installed on each floor must be flush with each other. However, in the past, sufficient consideration was not given to this aspect, resulting in concerns about strength and problems in corrective molding.

The present invention is aimed at solving the above-mentioned difficulties, and one embodiment of the present invention will be explained below with reference to the drawings. As shown in Fig. 2, the exterior wall material 1 of the frame A is replaced with a new exterior wall material 2, such as a curtain wall or spandrel (trade name).
As shown in FIG. 3, the present invention attaches a cap mounting member 4, which is a relatively long support hardware, to an old cap board portion 3 that is the top wall of the old exterior wall material 1 in the building frame A. They are arranged at required intervals in the direction and fixed with foundation studs (for example, Hole-in Anchor, trade name) 5. At this time, a long hole 4a is drilled in advance in the Kasagi mounting member 4, and when it is fixed with the foundation stud 5, the mounting member 4 is inserted into the long hole 4a.
Attachment pieces 4b, 4 are provided at both ends of each attachment member 4 by moving in the width direction on the old Kasagi portion 3 along line a.
It also serves to adjust the amount of protrusion of c into the room and outside, and to position it when installing the Kasagi unit 6, which will be described later. Next, the Kasagi receiving plate 6b is integrally fixed to the Kasagi receiving plate 6a in advance, and both widthwise ends of the Kasagi receiving plate 6b are bent into an L shape to form connecting pieces 6c and 6d, and the back side of the Kasagi receiving plate 6b is Mounting bracket 6e and reinforcing rib 6 in the longitudinal direction
A Kasagi unit 6 is manufactured by welding f together, and this Kasagi unit 6 is mounted on the Kasagi mounting member 4, and the mounting bracket 6 of the Kasagi unit 6 is attached.
e and the connecting piece 6d are welded to the mounting pieces 4b and 4c of the Kasagi mounting member 4, and the mortar 7 is appropriately filled between the reinforcing rib 6f and the Kasagi mounting member 4 to remove the old Kasagi part of the Kasagi unit 6. Consolidate support for 3. Further, on the outer surface of the building frame A, angle-shaped mounting hardware 9 consisting of a base plate part 9a and a mounting plate part 9b are arranged at a required number of positions on the old exterior wall material 1, and the base plate part 9a of each mounting hardware 9 is attached to the old exterior wall material 1. Basic planting rod 8
Each mounting hardware 9 is fixed to the outside and protrudes from the exterior wall material 1.
A vertical support frame 10 vertically arranged between the mounting plate portions 9b is erected and welded. This vertical support frame 10 also serves as a centering member for aligning and forming the outer wall material 2 flush. As shown in Figure 6, during long-term use, existing buildings are tilted due to uneven settlement and corrosion, and old exterior wall materials have become uneven. In addition, since the initial construction, the exterior wall materials 1a of each floor,
1b and 1c may not be formed flush with each other. Therefore, when welding the vertical support frame 10 to the mounting plate portion 9b of the mounting hardware 9, the vertical support frame 10
A long channel-shaped frame extending over the entire length of the old exterior wall material 1, excluding the window opening 12, is used, and the vertical support frame 10 is suspended or erected so as to be in a vertical state. For example, the upper and lower ends are temporarily welded to the side surface of the mounting plate part 9b of the mounting hardware 9, and then the external wall material 1 of each floor is attached.
A step of welding the vertical support frame 10 to the side surface of the mounting plate portion 9b of the mounting hardware 9 protruding from a, 1b, 1c is performed. After that, a channel-shaped horizontal support frame 11 extending horizontally between the vertical support frames 10 is erected and welded, thereby forming vertical and horizontal support frames 10 in a lattice pattern on the outer surface of the old exterior wall material 1. 11
are arranged and fixed, and the outer wall material 2 is spread and fixed to the horizontal support frame 11 by screws or the like. On the other hand, inside the window opening 12 of the building frame A,
As shown in the figure, the unnecessary projecting portion of the frame main body 13 of an old window frame is appropriately cut away, and the base portion remains on the concrete wall, and this old frame main body 1
3, one end of the auxiliary hardware 14 is welded to the upper frame 13a of the window opening 12.
A connecting metal fitting 15, which is a horizontal passage member, is made to protrude from the building frame A to the outside of the room and is welded to the projecting end, and this connecting metal fitting 15 is welded to the vertical support frame 10.

Reference numeral 19 denotes a newly installed aluminum window frame, and the upper frame 19a of the window frame has hook-shaped protrusions 20a, 20a formed opposite to each other on the anchor portion thereof, and the bifurcation of the anchor hardware 21 is formed on the upper frame 19a of the window frame. shaped clamping piece 2
1a and 21a are engaged, place the window frame 19 on the extension line of the vertical support frame 10 in the window opening 12 on the outdoor side of the old exterior wall material 1, and connect it to the connecting hardware 15. An anchor metal fitting 21 engaged with the upper frame 19a is connected via a suitable supplementary metal fitting 22a.

In addition, as shown in FIG. 5, one end of the auxiliary fitting 16 is welded to the lower frame 13b of the old frame main body 13, and the other end is made to protrude to the outside of the room, and a passing member extending horizontally is attached to this protruding end. The inverted L-shaped connecting hardware 17 is welded. Then, this connecting hardware 17 is welded to the vertical support frame 10 below the window opening 12 with an appropriate supplementary hardware 22b interposed, and
An anchor hardware 18 having a substantially stepped cross section that also serves as a reference board for the installation position of the new window frame 19 in the finding direction (front horizontal direction) and viewing direction (depth direction) is welded to this connecting hardware 17. By placing the lower frame 19b of the window frame 19,
It is precisely positioned by the horizontal piece 18a and the vertical piece 18b, and is screwed in this state.

Furthermore, in FIGS. 4 and 5, 23a, 2
3a are draining plates, and as shown in FIG. 5, the draining plate 23b on the lower frame side is provided with a recess 25 that covers the upper end of the new exterior wall material 2, and is connected watertight with a sealing material 28. be done. Also, 26
Reference characters a and 26b are tray plates installed from the new window frame 19 toward the indoor side.

In addition, in FIG. 3, the uppermost end of the new exterior wall material 2 is covered with a recess 24 formed by continuously bending the tip of the aforementioned Kasagi board 6a on the exterior wall side into an uneven shape.
In this recess 24, the Kasagi unit 6 and the outer wall material 2
and the uppermost end thereof are watertightly connected by a sealing material 27.

As explained above, the present invention arranges a plurality of angular mounting hardware at appropriate intervals in the vertical direction on an old exterior wall material, fixes the base plate of each mounting hardware to the exterior wall material, and each of these angular mounting hardware Since the vertical supporting frame is welded to the side surface of the mounting plate and is placed vertically to center the exterior wall material, the surface of the exterior wall material is uneven on each floor of the building and is not flush. Even if the surface of the exterior wall material is uneven, uneven, or sloped with respect to the vertical plane, the vertical support frame itself can be maintained in a vertical position. By welding to the mounting plate of each mounting hardware, this vertical support frame forms a so-called vertical reference frame, and the new external wall material is attached to this vertical reference frame via the horizontal support frame. By fixing this, the new exterior wall material can be installed flush along the vertical plane. In particular, when attaching the vertical support frame to the mounting hardware, it is important to note that due to unevenness or steps on the surface of the old exterior wall material, the distance between the surface of the exterior wall material and the vertical support frame, which is installed in a perpendicular state, may be limited when installing each mounting hardware. Although the length may vary depending on the location, the vertical support frame is welded to the side surface of each mounting plate rather than the tip of each mounting hardware, so the length of each mounting plate should have some margin. It is sufficient to set the vertical support frame vertically so that it can come into contact with the side surface of each mounting plate, and weld it at any contact position with the side surface. Therefore, since there is no need to individually set the length of the mounting plate portion of each mounting hardware according to the interval, attachment of the vertical support frame to the mounting hardware becomes very simple. In the present invention, a new upper frame of the window frame is placed on the extension of the lower end of the vertical support frame fixed in a vertical position, and a fixed connection is established between this upper frame and the adjacent vertical support frames. Since the metal fittings are connected to each other via the anchor metal fittings, the window frames on each floor are flush with each other and automatically aligned on a vertical plane without any special positioning. In addition, mounting hardware is welded to the old exterior wall material at appropriate intervals in the vertical direction, and a new window frame is installed via the vertical support frame welded to these multiple mounting hardware and the connecting hardware fixed to each vertical support frame. Since the upper frame is connected, the upper frame can be installed firmly.
