Description

Sealing structure for false middle stile of casement window

Technical Field

The utility model relates to the technical field of building door and window structures, in particular to a mullion sealing structure of a casement window false.

Background

The door and window is used as an important component of the outer facade of the building and bears diversified functions according to different positions of the door and window. In the field of architecture, doors and windows are divided into two main categories, an enclosure and an opening structure. The door and window of the enclosure structure has the main roles of resisting the influence of the external environment on the inside of the building (such as wind, rain and noise) and simultaneously carrying out the functions of heat preservation and heat insulation, and on the other hand, the door and window of the enclosure structure is opened to ensure the circulation of indoor and outdoor air and the free access of personnel.

The casement window is used as a common window type structure and is characterized in that a window sash rotates around an outer side window shaft, and the window sash rotates around an outer side horizontal shaft, so that an outward or inward casement opening effect is realized, and the window type structure is favored in the advantages of simple structure, strong stability, convenience in cleaning, ventilation, lighting and the like. However, most of the casement windows on the market today have middle stiles mounted in the middle, which reduces the visible area and limits the field of view during the window opening. The dummy mullion structure is an innovative design of a dummy mullion structure, can be used for overcoming the limitation brought by the traditional mullion, and achieves the maximum opening area by arranging the dummy mullion between two window sashes through the dummy mullion section bar, ensures that no shielding exists in the middle, and achieves the best visual effect. However, the existing dummy mullion structure still has a limitation in design, especially the upper end and the lower end of the dummy mullion are weak points for sealing the whole window, and if the sealing structure is improperly designed, the air tightness of the whole window may not reach the standard. With the increasing energy-saving and environment-friendly requirements of modern buildings, the shortage of the design may make the whole window incapable of meeting the related energy-saving and environment-friendly specifications.

For this reason, it is necessary to design an assembly that cooperates with the associated manufacturing process to ensure good sealing of the upper and lower ends of the dummy stiles.
