High wind pressure resistant plastic steel window structure

Abstract

The invention discloses a high-wind-pressure-resisting plastic steel window body structure which comprises a frame and a plurality of mullions. The mullions comprise plastic outer frames internally provided with middle separating parts and bottom supporting parts; glass and fixing clamping pieces are mounted on the two sides of the middle separating parts; steel lining cavities are formed in the middle separating parts and internally provided with supporting steel; the steel lining cavities communicate with the top faces of the middle separating parts and the top faces of the bottom supportingparts; and the supporting steel is matched with the interiors of the steel lining cavities in shape and closely attached to the inner side walls of the steel lining cavities. The overall wind pressure resistance of a window body can be enhanced, and the using safety of a plastic steel window is improved.

Description

technical field [0001] The invention relates to a window structure, in particular to a highly wind-resistant plastic-steel window structure capable of resisting high wind pressure and having a more stable structure. Background technique [0002] Plastic steel profiles are referred to as plastic steel, and the main chemical composition is PVC, so they are also called PVC profiles. It is a new type of building material that is widely used. Due to its physical properties such as rigidity, elasticity, corrosion resistance, and excellent aging resistance, it is usually used as a good substitute for non-ferrous metals such as copper, zinc, and aluminum. Because the doors and windows made of PVC profiles are not strong enough, steel is usually added to the cavity to enhance the firmness of the doors and windows. Therefore, plastic doors and windows made of steel inside the profiles are usually called plastic steel doors and windows. With the widespread use of plastic-steel doors a...

Problems solved by technology

[0003] For plastic steel profiles, the volume of the mold steel lining cavity of the "middle" profile is too small, such as figure 1 As shown, in the stile of the existing plastic-steel window structure, the steel lining cavity is only a part between the support part and the partition part, and the strength strengthening effect it can play is only suitable for areas with low wind pressure. In areas with high wind pressure, such as Shenzhen, that is, when the basic wind pressure is 0.75kpa or above, the existing middle mullion can only be selected in the division of about 1.1 meters, and the general window type must choose the splint material. As a result, the material and labor will be increased, and the sealing performance will be reduced. The size of the stile is small, and the overall grid area is small. It is impossible to install a grid with a larger glass area, resulting in a decrease in visible light performance; when the wind pressure is too large , it is easy to cause the overall damage of the form and cause a safety accident
