Description

[Detailed description of the invention] This invention relates to an improvement in the mounting structure of a double metal sash, which consists of an outer sash of the mold and an inner sash that is attached separately from this. The external part is airtight between the outer and inner sashes of the mold,
To provide a double metal sash mounting structure that achieves heat insulation and soundproofing, hides the exposed surface of wood, and facilitates construction.

In general, metal sashes such as aluminum sashes are airtight, and the so-called double sashes, which are made of double sashes, have a considerable insulation effect due to their excellent airtightness and the air layer created between the shoji of both sashes. It is well known that this can be obtained.

However, since the sash itself is actually made of metal, it has thermal conductivity specific to metal, and for example, in cold weather, the low temperature on the outer sash side is transmitted to the inner sash, causing problems such as dew condensation. is well known.

Therefore, as an improvement measure, the outer sash is attached externally and is installed separately from the inner sash. Although it has some effects, in this case, the mounting position of the outer sash and inner sash is The exposed wood surface in the middle is
Leaving it in that state not only impairs airtightness but also looks bad and poses a problem in construction.

This invention was created in view of the above-mentioned problems and to improve them.

Next, the mounting structure of the double metal sash of this invention will be explained based on the embodiment shown in the drawings.

Figures 1 and 2 show an embodiment of this invention, and Figures 3 and 2 show an embodiment of this invention.
Fig. 4 shows another embodiment of this invention in which the structure of the connecting part between the joining plate and the outer sash is changed, and Figs. 1 and 3 are longitudinal sectional views of each example. 2 and 4 are cross-sectional views of each example.

Reference numeral 1 common to each figure is an outer sash, 1' is an upper sash, 1'' is a lower frame, and 1'' and 1'' are left and right vertical frames.

Thus, only the lower frame portion 1'' extends toward the indoor side.

An upper edge plate portion 1a is provided, and other upper edge portions 1′ and left and right vertical frame portions 1′ are provided.
", 1'"' is an external structure that is attached to the outer surface of the wooden part 10 of the building opening.

2 is an inner sash that can be installed and adjusted according to the thickness of the wooden part of the building opening and its interior material; 2' is the upper part;
'' is the lower frame portion, and 2/// and 2//// are the left and right vertical frames.

Thus, the outer sash 1 is provided with an outer shoji 6, and the inner sash 2 is provided with an inner shoji 7.

3 is a joint plate made of a heat insulating material, which is connected to the upper edge plate 1a.
And the above-mentioned frame outer part covers the indoor side which is continuous with the part.

In this case, in the embodiments shown in FIGS. 1 and 2, the upper edge plate 1a is located below the end of the joint plate 3, but in the embodiment shown in FIG.
In the embodiment shown in FIG. 4, on the contrary, the upper edge plate 1a is located above the end of the joining plate 3.

No matter which of these two structures is adopted, the purpose of this invention will not be impaired.

Therefore, the heat insulating material used for the joint plate 3 may be either thermosetting or thermoplastic plastic, and it does not necessarily have to be plastic. Any material can be used as long as it is a material.

Reference numeral 4 denotes a tight member having heat insulating properties, which is interposed at the overlapping portion of the joining plate 3 and the inner sash 2.

Reference numeral 5 denotes a frame member, which is fixed to the indoor end of the inner sash 2 so as to cover the end of the interior material 9 of the building opening.

Reference numeral 8 denotes a packing material, which is interposed between the frame member 5 and the inner sash 2.

Since the double metal sash mounting structure of this invention has the above-mentioned configuration, it has the following effects.

(i) Heat conduction through the sash is prevented by the heat insulating effect of the joint plate.

(ii) If the joint plate is made wider, a heat insulating effect can be expected due to the air layer between the outer shoji and the inner shoji, and if a tight member is provided, this effect will become more pronounced.

(iii) By providing a joint plate and a frame member, the wooden part and interior parts can be stored better, and construction is easier.

(4) In the case of the embodiments shown in Figs. 1 and 2, the outer sash can be a commonly used external sash, so even after the construction, the inner sash can be attached. Since the mounting structure can be changed to the following, renovation is easy.

(v) Since the inner sash is installed so that one end overlaps the indoor side end of the joint board, and can be installed and adjusted according to the thickness of the wooden part of the building opening and its interior material, the wooden part of the building opening Also, even if the thickness of the interior material differs from building to building, the inner sash can be easily installed.

Particularly in openings of buildings where outer sashes are already installed, the inner sashes can be easily installed since the thickness of the main body and its interior materials differ from building to building.
