Description

Door and window outer frame section bar

Technical Field

The utility model relates to a door and window section bar technical field, more specifically say, relate to a door and window outer frame section bar.

Background

The door and window is one of important components of a building, is an important enclosure structure of the building, and has the function of transmitting and exchanging heat between the interior and the exterior of the building, although the door and window is small in area ratio, the heat transfer coefficient is large, the energy exchange between the interior and the exterior of the building through the door and window accounts for about 60% of the whole exchange energy, along with the continuous improvement of the national requirements on the energy-saving efficiency of the building, higher requirements are also put forward on the door and window, and the whole energy consumption of the building is reduced by improving the energy-saving effect of the door and window.

At present, related researchers in the industry make many researches to realize that a building can achieve a better energy-saving effect through a door and a window, for example, related technicians adopt low-radiation glass, hollow glass, vacuum glass, even vacuum or hollow glass with three glasses, two cavities and four or more cavities on the door and the window, and the temperature-induced color-changing sunshade glass is more concerned due to the special sunshade and heat release performance of the temperature-induced color-changing sunshade glass; the glass has excellent sun-shading performance in summer, if the glass is turned to the other side, the absorbed solar heat can be released towards the indoor all the time, and then the indoor heating is realized, but in the existing door and window structure, the doors and the windows are in staggered lap joint sealing when being closed, so that the doors and the windows cannot rotate at random angles, and the glass is limited by the existing door and window structure, and the existing thermochromic sun-shading glass is not widely applied in the field of the doors and the windows.

At present, relevant researchers have researched out doors and windows, the indoor or outdoor positions of which can be conveniently changed on the inner and outer surfaces, and the functions of adjusting the indoor sunlight irradiation quantity by the doors and windows are realized by combining the use of color-changing glass. However, in order to adjust the two sides of the glass indoors and outdoors, the design scheme of the door and window completely abandons the staggered lap joint sealing mode in the traditional door and window, and the gap between the inner frame and the outer frame of the door and window is sealed by moving the sealing part after the door and window is closed. But this kind of sealed mode need leave the cavity for sealed drive arrangement in the door and window frame structure in the use, and the setting of cavity will influence the setting to door and window frame structure, is unfavorable for door and window frame section bar's intensity, installation complex convenience and use durability. In addition, nowadays, with the continuous development of window functions, the door and window with two sides capable of exchanging indoor or outdoor positions will be applied to more and more door and window designs, and the door and window designs all involve the problems.
