The invention discloses a door and
window system with a hinged window structure. The door and
window system mainly comprises an outer frame, door leaves, a pseudo
mullion, a crimping wire and hollow glass, wherein the outer frame is formed by connecting an upper section, a lower section, a left section and a right section; two hinged door leaves are mounted in the outer frame; the door leaves are composed of four upper, lower, left and right door leaf sections and the hollow glass which is fixedly mounted in the middle of the door leaves through the crimping wire; the pseudo
mullion is connected with an indoor
leaf section of one of the two hinged door leaves so as to realize fastening through a
fastener; the frame sections and the door leaf sections are respectively composed of intermediate
alloy resin sections, outdoor aluminum
alloy sections and indoor wood sections; the aluminum
alloy sections are connected to the outdoor side of the alloy resin sections in a clamped manner; the wood sections are connected to the indoor side of the alloy resin sections through the
fastener; and the pseudo
mullion is composed of the alloy resin sections and the aluminum alloy sections clamped outdoors. The door and
window system disclosed by the invention has the characteristics of reasonable and compact structure, convenient use and mounting, as well as capacities of effectively solving the problem that a leakage point is easily produced at the overlap joint with the adoption of a form of adding the pseudo mullion and guaranteeing the
water tightness and air permeability performance of windows, and the like.
