High watertight door and window system

Abstract

The invention belongs to the field of building doors, windows and curtain walls, in particular to a high watertight door and window system, which includes a frame (1) and an opening sash (2); a CG-type heat insulation strip (102) is fixed on the frame (1) ; On the CG type heat insulation strip (102), a long-tail water vapor separation strip (502) is fixed; on the opening sash (2), a T-shaped heat insulation strip (202) is fixed; the long tail water vapor separation strip ( 502) is overlapped with the end of the T-shaped heat insulation strip (202); the CG type fan heat insulation strip (201) is fixed on the opening sash (2); the CG type fan heat insulation strip (201) The fan middle rubber strip (503) is fixed on the top; the top of the fan middle rubber strip (503) overlaps with the glass (7), and its bottom is embedded in the CG type fan heat insulation strip (201). The invention has good sealing and heat preservation performance, stable structure and high versatility, and can effectively meet the waterproof performance of building doors and windows.

Description

Technical field [0001] The invention belongs to the field of building doors and windows and curtain walls, and particularly relates to a high water tightness door and window system. Background technique [0002] In recent years, the global temperature has risen and the sea level has risen. At the same time, it has also brought more natural disasters. Heavy rains and floods are also one of many disasters. Rainwater disasters occur continuously all over the world. Snowstorms in winter and heavy rains in summer have seriously affected people's lives. In the hot summer days, typhoons frequently appear on the sea in my country. The heavy rains in previous years have mostly affected my country’s coastal cities. In recent years, it has gradually extended to inland cities, causing urban waterlogging. The construction of urban drainage pipelines is particularly important. If the flood cannot be discharged in time, it will cause rainwater to enter the room. Whenever a rainstorm strikes, t...

Problems solved by technology

The processing of the inner drainage hole is very time-consuming, and it will reduce the production efficiency for doors and windows. In addition, the drainage principle is equal pressure drainage and the air pressure of the water inlet cavity is equal to that of the outdoor side. The drainage point is set to the lowest point and enters the door and window structure. The water inside flows out naturally through the action of gravity. However, due to the lack of principle in the structural setting, the isobaric chambers set at the fixed glass positions of the existing door and window structures have gaps with the indoor side, that is, when there is a pressure difference between the indoor and outdoor sides, the inside of the door and window structure The pressure of the set drainage chamber is not equal to the pressure outside the outdoor, nor equal to the pressure inside the room, causing water to seep into the room along the gap
