Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to a thermal insulation and layered door and window. Background Art

[0002] Glass doors and windows are widely used in modern buildings. Currently, the most common ones are double-layer glass doors and windows. In order to improve their heat insulation and sound insulation functions, some existing products have triple-layer glass doors and windows, which are double-layer frames. The third layer of glass can be added to the existing double-layer glass doors and windows. For example, the patent with patent application number 201720972576.3 introduces triple-glass building exterior windows, which realize the transformation of existing double-layer glass doors and windows by installing the third layer of glass and the second window frame. However, when the third layer of glass is added, the added layer and the original glass layer are at normal pressure. As the weather changes, if the humidity inside the gas is too high, it is easy to produce water mist, and the thermal insulation and sound insulation effect of the normal pressure glass interlayer is much worse than that of negative pressure.

[0019] like Figure 1-Figure 4As shown, a thermal insulation layered door and window is composed of a main door and window ring frame 1, an exhaust fixed layered ring frame 2 and an L-shaped ring pressing piece 10;

[0020] The exhaust fixed layered ring frame 2 is fixedly installed on one side of the main door and window ring frame 1, and a side pressure groove 11 is provided on the inner ring side of the exhaust fixed layered ring frame 2, and an inserting ring groove 12 is provided on the bottom of the side groove wall of the side pressure groove 11. The cross section of the L-shaped ring pressing piece 10 is L-shaped, that is, it is composed of two vertical annular side walls, and one side wall of the L-shaped ring pressing piece 10 is inserted into the inserting ring groove 12, and a third glass layer clamping groove is sandwiched between the other side wall of the L-shaped ring pressing piece 10 and the side groove surface of the side pressure groove 11;

[0021] An exhaust fixed layer ring frame 2 is provided with an exhaust hole 16 connected with the inserted ring groove 12, an inner hole fixing frame 15 is installed in the exhaust hole 16, and the inner hole fixing frame 15 is connected and installed with a channel hole plug 13 through an elastic telescopic column 14, an L-shaped airway 19 is provided inside the L-shaped ring pressing piece 10, and an airway plug end groove 20 is provided on the end of the L-shaped airway 19 close to the exhaust hole 16, and the channel hole plug 13 is plugged into the airway plug end groove 20, so as to facilitate the blocking of the L-shaped airway 19;

[0022] A third glass layer 6 is sandwiched in the third glass layer clamping groove, and a plug ring groove is provided on the inner ring side of the main door and window ring frame 1. The first glass layer 4 and the second glass layer 5 are sandwiched and installed in the plug ring groove through a double-layer clamp plug 3.

[0023] like Figure 1-Figure 4 As shown, the utility model also discloses the following more optimized specific structures:

[0024] The side surfaces of the L-shaped ring pressure piece 10 are attached with pressure piece inner and outer pads 18 to increase its air tightness.

[0025] A third glass layer ring gasket 9 is fixedly mounted on the side groove surface of the side pressure groove 11 to increase the air tightness of the glass layer.

[0026] A plurality of fixing screw grooves 7 are provided on the outer side of the exhaust fixed layer ring frame 2 , and double frame fixing screws 8 are installed in the fixing screw grooves 7 . The main door and window ring frame 1 and the exhaust fixed layer ring frame 2 are fixed together by the double frame fixing screws 8 .

[0027] The outer hole end of the air extraction hole 16 is plugged with an air extraction hole plug 17, which serves as a second air passage sealing member for sealing after the air extraction is completed.

[0028] An inner groove ring 21 is installed in the groove of the fixing screw groove 7 , and a groove buckle cover 22 is installed at the groove opening of the fixing screw groove 7 .

[0029] like Figure 1-Figure 4The door and window with good air tightness shown in the figure is installed with a third layer of glass and its frame on the basis of the double-layer glass door and window, thereby improving its sound insulation and heat insulation functions.
