Description

[Detailed description of the invention] The present invention is a mounting device for a window frame (referred to as a modified window frame in this specification) having an outer peripheral edge of a complicated shape, such as an arched window, a round window, a rounded window, etc. Regarding.

By the way, ALC (foamed concrete) panels, which are known as lightweight concrete panel materials, have sufficient strength and good heat insulation properties in addition to their characteristic lightness, so in recent years they have been used in everything from high-rise buildings to private residences. It is widely used. However, one major drawback of this ALC panel is that the panel has built-in reinforcing bars, so it has poor workability, that is, it is difficult to cut. Specifically, when installing a window on the exterior wall of a building made of ALC panels, in the case of regular short-shaped windows, the building window opening can be relatively easily formed by cutting the ALC panel in straight lines both vertically and horizontally. However, when installing the above-mentioned deformed window frame, it is difficult to cut the ALC panel and it is not possible to form the window opening to the specified dimensions.

In view of the above, the purpose of this invention is to make it possible to easily attach a deformed window frame with a complex shape to the exterior wall of a building made of panel materials that are difficult to cut, such as ALC panels. Embodiments of the present invention will be described in detail based on the drawings.

It is fixed to the inner peripheral edge 30 of the window opening. Further, a joint material 37 is loaded in the gap between the outer periphery 28a of each outer wall supplementary template 28 and the inner periphery 30 of the window opening, and in the gap between the inner periphery 28b of the template 28 and the arched upper frame 1a. ing. According to this embodiment, the window opening inner peripheral edge 3
Since the upper edge portion 30a of 0 is tangentially close to the arched upper frame 1a, the area occupied by the templates 28, 28 is smaller than that of the outer wall supplement template 4 of the previous embodiment. As a result, the molding material for the template plate can be reduced, and since the template plate 28 is made of metal, the attachment angle member 31 can be easily attached. This has the effect of making the installation work easier.

In the above embodiments, only an arch-shaped window frame was illustrated, but FIGS. 11A and 11B schematically show embodiments of a round window frame 38 and a polygonal window frame 39. That is, in the case of the round window frame 38, the outer peripheral edge 40a of the outer wall supplement template 40 is made to match the shape of the inner peripheral edge of the rectangular window opening, and the inner peripheral edge 40a of the template 40 is made to match the shape of the inner peripheral edge of the rectangular window opening.
b to match the shape of the outer peripheral edge of the round window frame 38, that is, the circular shape, and fix this template 40 to the window opening,
Moreover, a round window frame 38 is attached to this template 40. Note that this template 40 is divided into upper and lower halves. The same applies to the polygonal window frame 39.
The explanation will be omitted.

As explained above, in the present invention, the outer periphery is formed to conform to the shape of at least a part of the inner periphery of the window opening of the building, and the inner periphery is formed to conform to the shape of at least a part of the outer periphery of the deformed window frame. An exterior wall supplement template formed to match the shape was placed in the required space between the building window opening and the deformed window frame, with the exterior surface of the template flush with the building exterior wall surface. ,
When installing a modified window frame such as an arched window frame or a round window frame on the exterior wall of a building made of exterior wall materials that are difficult to cut, such as ALC panels, window openings must be cut into the exterior wall of the building. In order to form an opening, it is necessary to make an opening in a simple shape, such as a rectangle, in which the vertical and horizontal sides are straight lines, making it easy to cut the wall material.As for the template for supplementing the external wall, it is possible to use the filling material as the external wall material. The material can be molded or cut into a predetermined shape using an easy-to-form material, and then installed by fitting it into the required part of the window opening. The window frame can be easily installed in a predetermined position on the exterior wall of the building. In particular, this external wall supplement template does not simply fill the space between the window opening and the deformed window frame, but is installed so that the external surface of the template is flush with the building's external wall surface. Since the wall forms part of the outer wall of the building in appearance, there is no need to overcoat the wall with mortar, cement, etc., that is, to finish the wall. In addition, since the surface side of the space between the window opening and the deformed window frame is hidden by the external wall supplementary shape material, the appearance of the mounting angle members and connecting members provided on the back side of the space is hidden. There is no need to be particular about the shape, so processing and installation are easy.

Furthermore, the outer wall supplement template of the present invention is capable of fixing a deformed window by means of a mounting angle member fixed to the window frame via an anchor plate that is fitted into a fitting groove provided on the outer periphery of the deformed window frame. Since it is attached to the frame and connected to the building window opening side by a connecting member fixed to the inner peripheral edge of the building window opening, the external wall supplement template can be attached to the deformed window frame on site. When installing, if the angle member for installation is fixed in advance to the template side by welding or screwing, simply fit the anchor plate provided on this angle member into the fitting groove on the deformed window frame side. Therefore, it becomes easy to attach the template to the deformed window frame, and the attachment position of the template can be adjusted to some extent depending on the relationship between the anchor plate and the fitting groove. The template is attached and fixed to the deformed window frame side via the mounting angle member and anchor plate as described above, and is also connected and fixed to the building window opening side by the connecting member, so it cannot be held in the fixed position. It can be stably held and will not wobble or deform even if wind pressure is applied to this external wall supplement template, and therefore the joint material loaded in the gap between the template and the window opening of the building will not crack. It will not fall off or fall off.
