Description

[Detailed Description of the Invention] The present invention relates to an improvement of a renovated exterior wall in which a new exterior wall is provided outside an existing window opening.

When the exterior wall of a conventional building becomes obsolete, if you want to leave the existing opening sash as it is and renovate the other walls, install multiple new panels on each wall outside the opening. It was constructed one by one. However, the work of attaching a large number of panels in the vertical and horizontal directions requires a great deal of effort and requires a large number of sealing points between each panel, which is not desirable for rain protection. The present invention aims to eliminate these drawbacks and improve the efficiency of on-site work, and the details will be explained below with reference to the drawings.

Figure 1 is a front view of the outer wall of the building renovated according to the present invention, and Figure 2 is a view taken from the arrow in Figure 1.
The side sectional view and FIG. 3 are similarly sectional views taken in the direction of arrows. In the figure, 1 is an opening into which an existing window sash 2 is fitted, as shown by the chain line. The renovated exterior wall will be stretched outside the room, leaving a slight gap between the existing exterior wall and the existing exterior wall. In the present invention, an upper frame 3 for attaching a new exterior plate 11 is attached to the outside of the upper edge of the opening 1 over the entire length in the longitudinal direction as shown in FIG. A lower frame is attached to the opening 1, and a vertical frame 5 is attached to both side edges of the opening 1 between the upper and lower frames. The upper frame 3 is a shape made of aluminum alloy, and its lower surface is horizontal, and a U-groove 6 for attaching an exterior plate is provided on the outdoor side along the entire length in the longitudinal direction, and a sealing material 7 is provided on the edge on the indoor side. A recess 8 is formed for filling. The upper surface of the upper frame 3 has a downward slope toward the outdoor side, and its end is connected to the lower surface 3a by a drain plate 9. The slope of the upper surface 3b of the upper frame ends at a line facing the U-groove 6, forming a rising wall 10 above the end thereof, which becomes a mounting abutting surface for an exterior plate 11, which will be described later.

Next, to explain the lower frame, it is also a section made of aluminum alloy, and its upper surface 4b has different levels, with the upper and lower levels both sloped downward toward the outdoor side, and the rising wall 10' forming the step is made of an exterior plate. 11 is attached to the contact surface. A recess 8 is formed at the edge on the indoor side to be filled with a sealant. The front edge of the upper surface 4b hangs down to form a draining plate 9.
form and connect with the lower surface. A U-groove 6', which is exactly the same as the U-groove of the upper frame, is provided on the lower surface 4a just vertically below the U-groove 6 provided on the upper frame. As will be described later, the upper end of the exterior plate 11 stretched between the openings of each level is fitted into this U-groove 6'. On the indoor side of the U-groove 6', the groove wall extends downward as it is for the convenience of attaching the lower frame to the structural member.

Next, the vertical frame 5 is provided between the upper frame 3 and the lower frame 4, the side facing the opening is a plane with a large depth, and the edge on the indoor side has a recess 8 filled with the sealing material 7. The front edge of the outdoor side, that is, the front plate 9' is located on the same vertical plane as the front plates called draining plates 9 of the upper frame and the lower frame, and forms the four peripheries of the opening 1. The side facing the outside of the opening 1 that is perpendicular to the front plate 9' has a small depth and ends with an outwardly bent surface, and this bent surface 12 abuts the side edge of the exterior plate 11. This will be the mounting surface.

Next, to outline the installation of the exterior plate, the outer wall in the illustrated example is a plate made of aluminum alloy, and the upper end of the exterior plate 11 is fitted into the groove 6 provided on the lower surface 3a of the upper frame 3 on both the left and right sides of the front opening. Then, its lower end abuts against the rising wall 10' on the lower surface 4b of the lower frame 4, and is locked with a machine screw 13 or the like.
Similarly, between the upper and lower openings, the entire surface thereof is the same exterior plate, but the height dimension is often different.The upper end is fitted into the U groove 6' provided on the lower surface of the lower frame 4,
Its lower end abuts against the rising wall 10 on the upper surface 3b of the upper frame 3 one level lower than the previous upper frame 3, and is locked with a machine screw or the like. And the side edge of the exterior board is the vertical frame 5
The end that abuts on is a bending plate 12 provided on the vertical frame 5.
It is fixed with machine screws. If the same work as described above is carried out on each floor, the renovation of the outer wall with new exterior panels will be completed, and if necessary, sealing material can be filled in the contact areas with the frame material, etc. In addition, 1 in Figure 2
Reference numeral 4 denotes a fastener that connects the old outer wall 15 of the building and the frame members 3 and 4 for strength, and the embodiment shows a pair of long chevron members.

As explained above, according to the present invention, the work can be done by simply inserting the panel exterior board cut to a fixed size between the upper frame and the lower frame or between the lower frame and the upper frame and fixing the lower end with machine screws. It is simple, requires few seals, and greatly contributes to shortening the construction period for on-site work performed while the building is in use.
