Aluminum alloy double-layer door and window structure

Abstract

The invention discloses an aluminum alloy double-layer door and window structure. A main window body is formed by combining an inner layer window and an outer layer window, wherein both sides of the main window body are provided with left inner frame outer side-hung vertical materials (1) and right inner frame outer side-hung vertical materials (2), the upper part of the inner layer window is provided with an upper window body I, the lower part of the inner layer window is provided with a lower window body I, an inner middle beam (3) is arranged between the upper window body I and the lower window body I, and left and right sides of the upper window body I and the lower window body I are arranged between the left inner frame outer side-hung vertical materials (1) and the right inner frame outer side-hung vertical materials (2); the upper window body I is a fixed window, and the lower window body I is a sliding window; the upper part of the outer layer window is provided with an upper window body II, the lower part of the outer layer window is provided with a lower window body II, and the upper window body II and the lower window body II are arranged between the left inner frame outer side-hung vertical materials (1) and the right inner frame outer side-hung vertical materials (2); and an outer side-hung middle upright I (4) is arranged between the upper window body II and the lower window body II, the upper window body II is a fixed window, and the lower window body II is an outer side-hung window.

Description

technical field [0001] The invention relates to a structure of an aluminum alloy double-layer door and window. Background technique [0002] At present, aluminum alloy door and window profiles are widely used in construction projects. Various sliding windows and casement windows abound. These door and window structures are all single-layer structures. Meet the requirements of special areas or high-end places. The main reasons are: first, the sealing material cannot meet the requirements, and the air tightness and water tightness are poor; second, the thermal insulation performance is poor, because it is a single-layer window, and the thermal insulation performance is poor; Bring trouble, also not attractive in appearance at the same time, thus it can be seen that existing single-layer aluminum alloy building doors and windows can no longer satisfy the market demand. Contents of the invention [0003] The invention provides an aluminum alloy double-layer door and window s...

The main reasons are: first, the sealing material cannot meet the requirements, and the air and water tightness are poor; second, the thermal insulation performance is poor, because it is a single-layer window, and the thermal insulation performance is poor; It brings trouble and is not beautiful at the same time. It can be seen that the existing single-layer aluminum alloy building doors and windows can no longer meet the market demand.
