Hidden drainage structure of sliding door and sliding door applied with same

Abstract

The invention provides a hidden drainage structure of a sliding door and a sliding door applied with the same, and relates to the field of building door and window curtain walls. The hidden drainage structure includes a drainage groove and a plurality of drainage pipes, the lower portion of the sliding door is connected with a door lower frame, the outdoor side of the door lower frame is providedwith the drainage groove, the door lower frame is provided with a plurality of first drainage holes, the first drainage holes communicate with the drainage groove through the drainage pipes, and wateroutlets of the drainage pipes are attached to the groove bottom of the drainage groove. According to the hidden drainage structure of the sliding door and the sliding door applied with the same, separate channel drainage of the outdoor side and the indoor side is realized, and the fact that the whole door drains smoothly to the outdoor in the use environment of high air pressure is ensured; a cavity is used for hiding the drainage structure, and the water tightness is improved; and through the structures of the drainage pipes and the outdoor drainage groove, the height difference between outdoor water flow and the water pressure of door lower frame profiles is formed, and rapid discharge of accumulated water of the door lower frame is accelerated by using the siphon principle.

Description

technical field [0001] The invention relates to the field of building doors, windows and curtain walls, in particular to a hidden drainage structure for a sliding door and a sliding door using the same. Background technique [0002] In the field of building doors, windows and curtain walls, watertightness has become an important indicator of doors, windows and curtain walls. In the coastal areas of our country, strong storms and rainy weather occur from time to time. The intensity and duration of rainstorms brought by typhoons are unprecedented. Doors and windows are prone to water leakage of varying degrees, which causes a lot of trouble to the residents. Not only is drainage difficult, but it also causes water to soak the interior walls and floors and damage the interior decoration.

[0002] In the field of building doors, windows and curtain walls, watertightness has become an important indicator of doors, windows and curtain walls. In the coastal areas of our country, strong storms and rainy weather occur from time to time. The intensity and duration of rainstorms brought by typhoons are unprecedented. Doors and windows are prone to water leakage to varying degrees, which causes a lot of trouble to the residents. Not only is drainage difficult, but it also causes water to soak the interior walls and floors, and damage the interior decoration.

[0003] The current industry mainly uses the following methods to improve the airtightness of doors and windows: first, adopt multi-channel sealing methods to prevent the infiltration of rainwater; second, improve the processing accuracy and reduce the gap where rainwater flows from the joints of door and window profiles Third, high-grade energy-saving doors, windows, windows, and window frames add intermediate sealing strips in the center, dividing the space between the frames and leaves into water-tight chambers and air-tight chambers, and prevent rainwater from entering the room through the air pressure of the chambers; Fourth, usually sliding doors The water tightness of the sliding door is largely determined by the height of the water retaining wall of the lower frame, but simply increasing the water retaining wall of the lower frame will directly affect the height of the interior decoration floor and affect the appearance. The level of performance is very limited, and it is difficult to meet the high-level watertight performance requirements
