Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a renovated exterior structure with a window, which is formed by attaching an exterior exterior with a window portion to the outdoor side of an exterior wall of an existing building in a two-dimensional manner.

The present inventor has previously discovered that when an existing building has a protruding part such as an eaves in a vertical cross section on the external wall surface, or an external wall part that extends to the outdoor side in a horizontal cross section, and an indoor side that is continuous with the external wall part via a step part, In cases where the existing building has a receding exterior wall, an exterior support frame is fixed to the exterior wall of the existing building, an exterior with a window is fixed to the outdoor side of the support frame, and the existing exterior wall is covered with the exterior. We proposed a modified exterior structure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a renovated exterior structure with a window that is suitable for cases where, for example, in the above-mentioned renovated exterior structure, the exterior is separated considerably from the existing exterior wall surface, making it impossible to reach the window from inside the room. The details will be explained below with reference to the drawings.

As an example, as shown in Figure 4, an exterior part F made of mortar or the like applied to the outer surface of a frame B of an existing building is applied to an outer wall having decorative protrusions P that protrude toward the outdoor side in a vertical section. This article describes the renovated exterior structure with exposed windows. In Figures 1 and 2, primary support members 2..., spacing members 3..., lattice-shaped second
An exterior support frame 1 mainly assembled from supporting materials 4 is fixed to a frame B of an existing building, and an exterior 5 is supported by the support frame 1. 1st above
The next supporting members 2... are straight members of H-beam steel, and the required number of them are vertically fixed to the frame B by anchor bolts 6 with appropriately wide lateral intervals, and at this time, the supporting members 2... A portion of each of the protrusions P in the fixed position has been removed. The spacing members 3 are appropriately short and small H-beam steels, which are fixed horizontally to the outdoor side surface of the supporting member 2 with their tips extending to the outdoor side beyond the protrusion P. 3 H at the tip of...
Secondary support longitudinal members 7 and secondary support cross members 8 of shaped steel
A lattice-shaped secondary support material 4 consisting of... is fixed, and the outdoor side surface of this lattice-shaped secondary support material 4 is positioned on the outdoor side of the above-mentioned protrusion P as an exterior support surface, and a panel is attached to this support surface. The exterior 5 formed by connecting the panel 9 and the window 10 is fixedly supported at the frame 11 of the panel 9 through the bracket 12, and the window 10 is moved to an appropriately retreated position on the indoor side from the exterior surface. It is supported using the exterior support frame 1 described above. In some cases, the panels 9 may be stretched directly onto the exterior support surface using the brackets 12 without using the frames 11.

The support structure of the window portions 10 is as follows.
Primary support material 2 in the installation space of the window section 10...
The upper and lower horizontal members 13 and 14 are fixed horizontally at positions corresponding to both the upper and lower sides of the window installation space, respectively, and the upper and lower horizontal members 13 and 14 are
The upper and lower crosspieces 15..., 16... are respectively connected between these and the secondary support horizontal members 8, 8 located at the same height, and auxiliary members 17, 18 are connected to these upper and lower crosspieces. The upper and lower parts of the window frame 19 are supported respectively. In the space between the window part 10 and the exterior surface, the upper surface of the space is covered with an upper cover 20, the lower surface with a lower cover 21, and the left and right sides with left and right covers 22 and 23, respectively,
In addition, in the space between the window part 10 and the existing building, the upper surface is covered with an upper cover 24, the lower surface is covered with a lower cover 25, and the left and right sides are covered with a left cover 26, a right cover 26,
Each is covered with 27.

In addition, for old window frames S of existing buildings, use the cover 2 above.
4, 25, 26, and 27, respectively. However, if necessary, the old window frame S mentioned above may be
It can also be used to form a double-glazed window with the window section 10 of the new exterior 5.

In addition, the second window should be located in the window installation space.
The next support vertical members 7 may be passed through the space as is, but in this example, the portion corresponding to the space is removed.

This makes it convenient when cleaning the window portions 10 by extending your hand from the indoor side.

Although the window portions 10 in the above example are fitted windows, they can also be windows that can be opened and closed in the present invention. In this case, the window can be opened and closed easily by extending your hand from inside the room.

In some cases, the primary support member in the above example may be oriented horizontally and fixed to the frame.

The present invention is not limited to a renovated exterior wall having a protrusion in a vertical cross section as in the above example, but is applicable to various renovated exterior structures in which the exterior is arranged with a considerable distance between it and the existing exterior wall surface. Of course, it will be implemented in the future.

According to the exterior structure for renovating an exterior wall of an existing building with a window according to the present invention, the primary support member of the exterior support frame is attached to the exterior wall surface, and the
Because the structure is such that the secondary support material is attached and the exterior panel is attached to the outdoor side of the secondary support material, it is possible to easily renovate an existing building that has a protrusion on the exterior wall surface. Even if the window is quite far away from the existing exterior wall surface, you can reach out from inside the room and freely clean the window, open and close it, etc., and it is very convenient to use.
