Description

Technical Field

[0001] The utility model belongs to the technical field of building doors and windows, and in particular relates to a light-transmitting, shading and heat-insulating conversion frame adapted to large windows of buildings in cold regions. Background Art

[0002] The open balcony door should have good airtightness. The specification stipulates that the airtightness level of the open balcony door in severe cold areas should not be lower than level 6 specified in the national standard "Classification and Test Methods for Airtightness, Watertightness and Wind Pressure Resistance of External Doors and Windows of Buildings" GB / T7106-2008. The airtightness level of the external windows and open balcony doors on the 1st to 6th floors in cold areas should not be lower than level 4 specified in the national standard "Classification and Test Methods for Airtightness, Watertightness and Wind Pressure Resistance of External Doors and Windows of Buildings" GB / T7106-2008, and should not be lower than level 6 for 7 floors and above.

[0003] Due to the cold climate, most balconies are closed. There should be partitions, doors and windows between the closed balcony and the directly connected room. Some developers often omit the partition between the balcony and the room in order to increase the area of ​​the room to attract buyers. This practice is not advisable. On the one hand, it is easy to cause excessive heating energy consumption. On the other hand, if it is not handled properly, the room may not reach the design temperature, and the balcony roof and the railings under the windowsill may condense. If the partition wall between the balcony and the room is omitted, the outer surface of the balcony must be treated as the outer protective structure of the room. In this way, the shape coefficient of the building is likely to exceed the limit specified in the specification, and the window-to-wall area ratio in the north is also likely to exceed the provisions of the specification. In this way, if one of the indicators specified in the specification is not met, the building heat consumption index should be calculated. The calculation result is often that the insulation layer is relatively thick, and the quality is difficult to guarantee from the construction point of view. It is also relatively wasteful from an economic point of view. According to the requirements of building energy conservation and local climatic conditions, the insulation structure of the building balcony, on the basis of correct thermal calculation, after technical and economic comparison, a reasonable balcony insulation design is one of the more reasonable treatment methods. In the specific implementation of this process, the insulation measures at the large-area windows of the balcony lack a unified and standardized treatment method. Specifically, the light transmission and thermal insulation performance are poor. Windows are used to allow light or air to enter the room. In order to block light, shading devices such as curtains and folding curtains will be installed on the windows. In winter in cold areas, cold wind easily enters the windows, resulting in indoor temperature differences. Therefore, shielding and thermal insulation devices will be installed in the windows, which can achieve shading and thermal insulation. However, the structure of the existing shielding and thermal insulation devices is not perfect and is difficult to adapt to cold area buildings. The problems analyzed are mainly concentrated on:

[0004] 1. The shielding and heat-insulating device is an integral type and is bonded inside the window during installation. It is easy to fall off, inconvenient to disassemble, and has low performance for repeated use.

[0005] Second, the shielding and heat preservation device is a push-pull folding shielding and heat preservation curtain, which is convenient for shading, heat preservation and folding, but there will be the following problems:

[0006] First: When the cold wind is strong, the wind will enter the room from the gap between the folding thermal insulation curtain and the horizontal support strip, resulting in poor thermal insulation performance and failure to achieve the desired effect.

[0007] Second: When the movable frame drives the folding thermal insulation curtain to cover and fold, the movable frame will shake and get stuck. The sealing of the upper and lower parts will be affected by the outside world, resulting in uneven sealing performance at different positions. It is also easy for the folding thermal insulation curtain to fail to cover and fold smoothly.

[0008] The on-demand shading sealing and the conversion of light-through sealing cause dynamic changes in the sealing performance of the mating components, which are difficult to be compatible. It is difficult for mobile sealing accessories to exert stable sealing performance during the specific implementation process. Utility Model Content

When shielding and heat preservation are needed, The movable frame 4 is pushed to the left so that the movable frame 4 is clamped in the longitudinal support strip 2 on the left, and is sealed with the movable frame 4 through the sealing strip in the longitudinal support strip 2 on the left. When the movable frame 4 moves to the left, the curved guide sealing strip 4-1 on the movable frame 4 can be guided, and the supporting balls can slide at the same time, so that the movable frame 4 is not easily stuck. The front end of the sealing strip 6-3 of the telescopic seal 6 will move with the movable frame 4, and the sealing strip 6-3 will realize the sealing between the transverse support strip 1 and the folding shielding insulation curtain 3. When the movable frame 4 is folded, the folding shielding insulation curtain 3 is folded, and the sealing strip 6-3 is automatically rolled up by the elastic roller body 6-2, which is convenient for the folding and storage process of the sealing strip 6-3.
