Description
Technical Field
The utility model relates to the technical field of outward opening doors and windows, in particular to a bridge-cutoff structure and a bridge-cutoff section.
Background
The outward opening door and window is an important form of door and window opening mode, and is named because of the characteristic that the opening direction of the outward opening door and window faces the outside of a building. The outward opening door and window has wide application because of not occupying indoor space. With the overall improvement of social life quality demands, the outward opening doors and windows are evolved from the traditional outward opening forms to various or combined forms which can be tilted to one or more directions so as to adapt to the specific functional demands of more individuals such as indoor micro ventilation and the like.
Door and window profiles are the main structural frames of doors and windows, and for out-opening doors and windows, generally comprise an out-opening door and window frame profile structure (comprising an inner frame and an outer frame) connected with a wall body, and an out-opening door and window sash body profile structure (comprising an outer frame and an inner frame) for installing a door/window sash (fan). Because the thermal insulation requirement of the outward opening door and window, the inner frame and the outer frame are not directly connected, and a corresponding bridge-cut-off structure is arranged on the premise of connecting the inner frame and the outer frame, so that the thermal conduction between the inner frame and the outer frame is cut off, and the thermal insulation requirement is met.
Therefore, the bridge-cut-off structure of the existing outward opening door and window system has the following technical problems:
(1) The sealing rubber strip of the existing outward opening door and window system is usually arranged on the outdoor edge side of the outward opening door and window frame section bar structure or the outward opening door and window sash body section bar structure, and the sealing rubber strip is connected and fixed with the outer frame; however, in some cases, in order to improve the overall tightness of the out-opening door and window system, the sealing structure formed by the sealing rubber strips needs to be moved inwards, and at this time, the sealing rubber strips need to be fixed on a bridge-cut-off structure for connecting the outer frame and the inner frame, so that the fixing of the sealing rubber strips and the forming of the sealing structure cannot be realized by the existing bridge-cut-off structure.
(2) Under some scenes, after external power water breaks through a first sealing structure arranged on the outward opening door and window system, the possibility that rainwater enters the room is increased, the action of the existing bridge-cut-off structure cannot normally block the rainwater breaking through the first sealing structure, and the bridge-cut-off structure is only used for connecting an outer frame and an inner frame, so that in the outward opening door and window system with high sealing performance, miniaturization and light-weight requirements, the function is single, and precious space in window profiles is wasted.
