Description

Screen window opening sash of section bar and direct-connected window frame

Technical Field

The utility model relates to an auxiliary facility for building doors and windows, in particular to a section bar and a screen window opening sash directly connected with a window frame.

Background

At present, the window in the building house structure generally adopts an inward opening window structure form; the window section bar comprises a plastic section bar, an aluminum-plastic section bar, an aluminum bridge-cut-off section bar and the like, and a structure that a screen window sash is directly connected with a window frame is not designed in the section bar structure. Therefore, the screen window is made into a complete screen window and then connected with a window frame to form the anti-mosquito screen window in the market. The window screen with the frame matched with the inward opening window comprises a combined window screen with a frame middle frame and a combined window screen with a frame middle frame capable of being disassembled and assembled inwards or outwards, wherein the frame middle frame is a window screen window frame, the window screen window is connected with the window screen window frame and is also a frame, and the frame connected with the window screen window is connected with the window frame to form the window screen capable of preventing mosquitoes. The screen window with the frame has the advantages of attractive appearance and durability, and has the defects that the screen window sash is arranged on the periphery in the ventilation plane of the window sash, the frame edge of the sash and part of the frame edge connected with the sash are within the ventilation area of the window, the ventilation area is occupied, and the ventilation volume of the window is reduced; such as: the size of the ventilation plane at the opening part of the window sash is 50 cm in width and 120 cm in height, the ventilation area is 0.6 square meter, after the window screen is installed, the width of the window screen frame edge is increased by about 5 cm on the upper side, the lower side, the left side and the right side, the size of the ventilation plane is changed into 40 cm in width and 110 cm in height, the ventilation area is also changed into 0.44 square meter, and the ventilation area is reduced by about 27%. And due to the structural form of the inward opening window, the width of the window sash is not suitable for being too wide, and the window sash is easy to deform to influence use. Therefore, a structure with a large fixed opening and a small opening is often adopted, namely the area for opening and ventilating is small, and the area for fixing is large; on the premise that the ventilation area is not enough, the window screen frame edge connected with the window sash opening part occupies a large ventilation area, the ventilation area required by people in daily life is not enough, and the normal life of people is influenced. The screen window with the connecting structure determines that the screen window sash is required to be in the ventilation plane of the screen window sash, otherwise, the screen window sash cannot be detached, and no method is available. The screen window with the structure has more materials and high labor cost, so the screen window has high selling price in the market. In addition, after the screen window sash is taken down, the frame connected with the screen window sash still remains on the window frame, the original window frame is thickened, when people clean the glass, arms need to bypass the thickened frame edge to clean the glass, and the glass is inconvenient.
