Aluminum alloy outward opening window with good sealing performance

Abstract

The invention discloses an aluminum alloy outward opening window with good sealing performance. Three seals are arranged in the fixed or lap joint position between a leaf frame and a frame or in the lap joint position between the leaf frame and a mullion: two sealing rubber strips A and B are in a lap joint on the indoor side, a sealing rubber strip C, on the outdoor side, is in a lap joint at the outdoor side of the frame or the mullion and fixed in a groove at the outdoor side edge of the leaf frame, and an equipressure rubber strip D in the middle; and the size of a fixed molding cavity or a lap joint molding cavity between the leaf frame and the frame or a lap joint molding cavity between the leaf frame and the mullion is as follows: a distance from a rotating hardware surface on the leaf frame to a hardware surface on the frame or the mullion accords with an installation size of common hardware, and the protruded outmost end surface of a stop wall is level with the rotating hardware surface; and a distance from the protruded outmost end surface of a boss to the outmost end surface of a groove for fixing the sealing rubber strip A satisfies the depth requirement of glass into the groove. The aluminum alloy outward opening window is excellent in heat insulation, sound insulation, energy conservation and heat preservation effects, and is low in hardware manufacturing cost.

Description

technical field [0001] The invention relates to a door and window for building, in particular to an aluminum alloy window opening outwards. Background technique [0002] In recent years, with the shortage of wood, broken bridge heat-insulated aluminum alloy doors and windows occupy a part of the door and window market due to its advantages of light weight, high strength, and low cost. Most of the second- and third-tier cities choose economical broken bridge heat-insulated aluminum alloy doors and windows. Alloy windows and doors. However, the heat transfer coefficient of aluminum alloy materials is higher than that of doors and windows made of other materials, which is not conducive to heat preservation and energy saving. With people's emphasis on the environment, the energy-saving requirements for doors and windows are constantly increasing.

Problems solved by technology

However, the heat transfer coefficient of aluminum alloy materials is higher than that of doors and windows made of other materials, which is not conducive to heat preservation and energy saving.

With people's emphasis on the environment, the energy-saving requirements for doors and windows are constantly increasing. In order to improve the thermal insulation effect of aluminum alloy doors and windows, the current treatment method adopted in the industry is to add heat insulation strips to aluminum alloy profiles to block heat conduction. Although this method solves the problem of heat conduction, the structure of the fixed or overlapping cavity between the fan frame of the opening fan and the fixed or overlapping frame or stile leads to poor sealing performance at the fixed or overlapping position, and cold air It is easy to enter the room through the gaps of closed doors and windows, and its thermal insulation and sealing effect is not ideal. It also has the problem of high cost of doors and windows caused by unsuitable frame profiles and hardware.
