Automatic limit support device for hanging windows on curtain wall

Abstract

The invention provides an automatic limiting and supporting device for a top-hung window of a curtain wall. The automatic limiting and supporting device comprises a supporting arm and a hinge device, wherein the supporting arm is movably arranged on a window frame and is provided with a U-shaped groove; the hinge device comprises a window frame rod part, a window sash rod part, a connecting rod part and a slide-support connecting rod, wherein the window frame rod part is fixedly arranged on the window frame; the window sash rod part is fixedly arranged on a window sash; the two ends of the connecting rod part are articulated with the window frame rod part; the two ends of the slide-support connecting rod are articulated with the window sash rod part; a T-shaped welding block matched with the U-shaped groove is arranged on the slide-support connecting rod. The invention provides a limiting and supporting device which is simple, high in efficiency, convenient to install and selective in opening angle; the limiting and supporting device is capable of solving the problem that in national market, a hardware part for opening the top-hung window of the curtain wall generally adopts a 'slide-support + air support' combination way, and the manufacturers only produce hardware parts applicable to relatively large windows; therefore, the automatic limiting and supporting device provided by the invention is capable of making up the blank of 'slide-support + air support' integration of a small-size top-hung window and solving the problem that the existing structure customization cost is considerable.

Description

technical field [0001] The invention relates to an automatic limit support device for hanging windows on a curtain wall. Background technique [0002] For the small-height top-hung windows in curtain wall engineering, the upper limit device in the domestic market cannot meet the requirements for the integration of sliding braces and wind braces. Only the sliding brace is installed without the positioning and supporting functions of the wind brace. After the window sash is opened, it will automatically close due to the weight of the glass. Even if the friction force of the sliding block is partially strengthened, the window sash can be temporarily supported, but there is no effective support system. , Under the action of external force such as strong wind, the support of friction force is easy to fail, and in severe cases, impact may even occur, causing damage to the window sash and glass, posing a safety hazard.

Problems solved by technology

[0002] For the small-height top-hung windows in curtain wall engineering, the upper limit device in the domestic market cannot meet the requirements for the integration of sliding braces and wind braces

Only the sliding brace is installed without the positioning and supporting functions of the wind brace. After the window sash is opened, it will automatically close due to the weight of the glass. Even if the friction force of the sliding block is partially strengthened, the window sash can be temporarily supported, but there is no effective support system. , under the action of strong wind and other external forces, the support of friction force is easy to fail, and in severe cases, impact may even occur, causing damage to the window sash and glass, posing a safety hazard

[0003] In the domestic market, the combination of "sliding brace + wind brace" is generally adopted for the opening hardware of the hanging window on the curtain wall, and the manufacturer only produces hardware that meets the larger window type.
