Description

[Detailed description of the invention] The present invention relates to a double sash with excellent heat and sound insulation performance, which is made by combining an outer sash consisting of upper and lower sliding windows and an inner sash with sliding doors installed on the upper and lower sides. It is something.

Double-glazed windows have traditionally been used in cold regions to protect against the cold, but recently they have come to be used in extremely hot regions to protect against the heat, and in urban areas for soundproofing purposes.

Traditionally, double sashes, which make up the majority of double-glazed windows, were generally made of double glazing, but as they were cumbersome and expensive to manufacture, recently the outer and inner sashes have been assembled separately and are now integrated into one. A double sash made by combining these two has been put into practical use.

By the way, as it is well known, aluminum sash has good heat conduction, so a heat insulating material is interposed between the outer sash and the inner sash to improve the heat insulation effect, but it is not always sufficient.
The indoor temperature may drop and condensation may form.

This invention was made in order to solve the conventional problems as mentioned above. By interposing heat insulating material to block heat conduction,
The purpose is to obtain a double sash with significantly improved heat insulation and sound insulation effects.

In order to achieve the above-mentioned purpose, the double sash according to the present invention has connecting parts on the indoor side of the upper frame, the lower frame, and the left and right vertical frames, and also connects vertically at predetermined intervals on the indoor side of the lintel. An outer sash with glass fixed thereto is provided between the upper frame and the lintel, and between the lintel and the lower frame, and connecting portions are provided on the outdoor side of the upper frame, the lower frame, and the left and right vertical frames, and the outdoor side of the lintel is provided. connecting parts are provided above and below at predetermined intervals, and an inner sash is provided with a sliding door installed between the upper frame and the lintel, and between the lintel and the lower frame, and between each connecting part of the outer sash. The outer sash and the inner sash are integrally connected via a heat insulating material.

The present invention will be explained below using the drawings. Fig. 1 is a longitudinal cross-sectional view of the embodiment of the present invention, and Fig. 2 is a cross-sectional view taken along line I-I. This is an inner satsushi with sliding doors installed.

In the outer sash A, 1 is an upper frame, which includes a web 11, a fixing groove 12 for the glass a provided on the lower surface of the web 11, and a connecting portion 13 formed on the indoor side of the flange 110.

Reference numeral 2 denotes a lower frame, which includes a web 21 inclined toward the outdoor side, a connecting portion 23 bent downward from the indoor end of the web 21, and a connecting portion 23 extending upward from the indoor side of the web 21 and then bent at an angle toward the indoor side. The connecting portion 24 includes a connecting portion 24, a fixing groove 22 for the glass b, and the like, which is provided so as to protrude from below the connecting portion 24 toward the outside of the room.

3 is the lintel, 31.32 is the glass a installed above and below it,
The fixing grooves 33 and 34 of b are connecting portions protruding from the indoor side of the lintel 3 at predetermined intervals.

Reference numerals 4 and 4a are vertical frames of the outer sash A, each of which has a fixing groove 41.41a for the glass b on the inside, and a connecting portion 42.42a on the indoor side.

In the inner sash B, 5 is an upper frame, a mounting piece 52 provided at the indoor end of the web 51, guides 53, 54 for the sliding doors c and d provided on the lower surface, and upward from slightly inside the outdoor end of the web 51. After being extended, it is made up of a connecting portion 55 and the like that extends toward the outdoor side at a predetermined distance S from the web 51 and parallel to the web.

6 is a lower frame, a web 61, and a mounting piece 6 provided at the indoor end of the web 61.
2. Sliding doors installed on the top surface e, f ray/l/63,
64. The web 61 includes a heat insulating material mounting portion 65 formed to be inclined downward from the outdoor end of the web 61 and a connecting portion 66 extending downward from the mounting portion 65 and formed at its lower end.

7 is a two-box-shaped lintel with rails 71 and 72 for a sliding door C1d installed on the top surface, and a sliding sliding door e installed on the bottom surface.

It consists of guides 73, 74 of f, connecting parts 33, 34 provided on the lintel 3 of outer sash A, and connecting parts 75, 76 protruding toward the outdoor side with a gap V between them.

Reference numerals 8 and 8a denote vertical frames of the inner sash B, and fitting portions 81 and 81a for the sliding doors e and f are provided on the inside, respectively, and connecting portions 82 and 82a are formed on the outdoor side.

(2) 1 to H8 are heat insulating materials interposed at each connecting portion of outer sash A and inner sash B.

Next, an example of work in which a double sash consisting of the above-mentioned parts is attached to an opening in a building will be explained.

First, assemble the upper frame 1, the lower frame 2, the left and right vertical frames 4, 4a, and the lintel 3, and fix the glasses a and b to make the outer sash A look more stylish. (Good), attach heat insulating materials H2, H3, and H4 to the connecting portion 13 of the upper frame 1 and the connecting portions 33 and 34 of the lintel 3, respectively.

In addition, the upper frame 4, the lower frame 5, the left and right vertical frames 8, 8a, and the lintel 7 are assembled to form an in-works sash B, and the insulation material attachment part 6 of the lower frame 6 is assembled.
Attach the heat insulating material H5 to 5 and secure it to the opening of the building.

Next, the heat insulating materials H6, H7, and H8 are applied (or bonded or fastened) to the connecting parts 66, 82, and 82a of the inner sash B, respectively.
Then, the heat insulating material H2 attached to the upper frame 1 of the outer sash A is inserted into the groove formed by the web 51 and the connection part 55 of the upper frame 5 of the inner sash B, and the connection provided on the lintel 3 of the outer sash A is inserted. Part 33
, 34 (insulating materials H3 and H4 are attached) are inserted between the connecting parts 75 and 76 provided in the lintel 7 of the inner sash B,
A heat insulating material H1 is interposed between the outer end of the web 11 of the upper frame 1 of the outer sash A and the outer end of the connecting portion 550 of the inner sash B, and the two are connected with screws.

At this time, the lower frame 2 of the outer sash A comes into contact with the inner sash B via the heat insulating materials H5 and H6, so that they are connected with screws.

In addition, the vertical frames 4 and 4a of the outer sash A are also made of heat insulating material H.
It abuts against the vertical frames 8, 8a of the inner sash B via 7, H8.

In this way, it is possible to realize a double sash in which all the connecting parts of the outer sash A and the inner sash B are abutted and connected via the heat insulating material.

It goes without saying that the above mounting order is an example and may be changed as appropriate depending on the site or other circumstances.

Further, the shapes, dimensions, etc. of each constituent part, connecting part, etc. are not limited to the above embodiments, and can be changed as appropriate without departing from the gist of the present invention.

As detailed above, in this invention, the outer sash is a folding window and the inner sash is a sliding door, so the outer sash is always closed and there is no risk of outside air intruding.Therefore, the insulation effect is greatly improved. In addition, the outer sash and interior surface can be easily cleaned by opening the sliding doors.

Furthermore, since the connecting parts of the inner and outer sashes are all interposed with a heat insulating material, the heat insulating effect can be further enhanced, and there is no risk of condensation forming.

Therefore, it is highly effective in practical use.
