High-heat-preservation windproof broken bridge aluminum alloy door and window

Abstract

The invention discloses a high-heat-preservation windproof broken bridge aluminum alloy door and window and relates to the field of broken bridge aluminum alloy doors and windows. Cross beams are symmetrically arranged at the upper end and the lower end of a window frame, outer grooves are formed in the middles of the front faces of the cross beams, fixing holes are symmetrically formed in the two ends of the outer sides of the cross beams, and hook plates are fixedly installed on the end faces of the two sides of the cross beams; the section of the hook plate is of an L-shaped structure, a glue injection hole is formed in the end face of the L-shaped bottom of the hook plate, and a strip-shaped inner inserting groove is formed in the bottom end in the hook plate and formed in the bottom of the horizontal plane of the glue injection hole. According to the high-heat-preservation windproof type broken bridge aluminum alloy door and window, the defects of an existing broken bridge aluminum alloy door and window can be overcome, the connecting position of the transverse beam and the longitudinal beam of the door frame is more stable through the special corner connector, the airtightness is higher while glue injection is facilitated, in addition, a user can complete assembly of the windproof mechanism through convenient pulling, and the practicability is high. The ventilation performance of the door and window can be kept in non-disaster weather, and meanwhile loading of the windproof component can be rapidly completed in gale weather.

Description

technical field [0001] The invention relates to the field of broken bridge aluminum alloy doors and windows, in particular to a high thermal insulation and windproof type broken bridge aluminum alloy doors and windows. Background technique [0002] The broken bridge aluminum doors and windows are made of heat-insulating broken bridge aluminum profiles and insulating glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, waterproof and so on. The heat loss of doors and windows is reduced by half, and the heating cost is reduced by about 30%. [0003] Common problems of the existing plate cutting devices are: in the prior art, the aluminum alloy doors and windows need to be connected and fixed at four corners during the assembly and molding process, and corner code connectors are often used for butt joints, and the corner code is indispensable for connecting L-shaped right-angle intersecting components However, the connection accuracy...

Problems solved by technology

[0003] The common problems of the existing plate cutting device are: in the prior art, the aluminum alloy doors and windows need to be connected and fixed at the four corners during the assembly and molding process, and corner connectors are often used for docking, and corner connectors are indispensable for connecting L-shaped right-angled intersecting components However, the connection accuracy of general-purpose corner codes is not enough, which will easily lead to shaking of the joints. In addition, the airtightness and thermal insulation performance of corner nodes are also insufficient. At the same time, the windproof design of aluminum alloy doors and windows in the prior art is unreasonable, and its mechanical covering It is not convenient for users to operate outside the doors and windows, and the lack of windproof airtightness in disaster weather will also take away indoor heat, so the applicability is not strong
