Description

Technical Field

[0001] The invention relates to the field of design and construction of upper-hung windows on curtain walls, and in particular to a hook-type upper-hung window anti-detachment safety hook structure. Background Art

[0002] Top-hung windows are the most commonly used opening windows in curtain walls. They are generally connected by a hook. The window sash and window frame are hinged with a full-length axis, so they have a large bearing capacity. The window sash is hinged to the window frame with a hook. By setting an activity space in the window frame, the hook fixed on the upper edge of the window sash can rotate in the activity space, thereby realizing opening and closing to meet the use requirements of larger-sized opening windows.

[0003] At present, most hook-type top-hung windows do not have anti-slip safety hooks. In order to prevent the window sash from accidentally falling off when the window sash is opened, a pressure block is usually installed on the outside of the window sash hook to prevent the window sash from falling off. This type of hook-type opening window sash has the following problems in engineering installation: 1. Due to the structural reasons of the structure itself, the space at the top of the window sash is very small, and it is inconvenient to install the anti-slip pressure piece later, and the anti-slip pressure piece is usually missing; 2. The anti-slip pressure block can only be checked outdoors to see if it is installed, and quality control is difficult. 3. If the installation error cannot be guaranteed during the construction process, the window sash will be subjected to excessive upward reaction force from the wind brace during improper operation by non-professionals, causing the limit measures of the suspended window sash to fail, thereby causing the suspended window sash to retreat and unhook as a whole, resulting in the safety hazard of the window sash falling off and injuring people. Therefore, it has become a top priority to develop a new type of anti-slip safety hook structure for suspended windows that is safe, reliable, easy to install, and safe to slip off. Summary of the invention
