Fireproof and external sunshade integrated window

Abstract

The invention relates to a fireproof and external sunshade integrated window which comprises a rectangular window frame composed of an upper cross beam, a lower cross beam, a left column and a right column. The fireproof and external sunshade integrated window is characterized in that an upper-middle cross beam connected with the left column and the right column and parallel to the upper cross beam and the lower cross beam is arranged between the upper cross beam and the lower cross beam of the window frame, a window curtain device is arranged in the space formed by the upper-middle cross beam and the upper cross beam, an inner baffle is arranged between the upper-middle cross beam and the upper cross beam, and a bearing section bar is made from a glass fiber reinforced polyurethane material. According to the innovation point, the fireproof and external sunshade integrated window has the special advantages that the glass fiber reinforced polyurethane material is applied to the window section bar, innovation point is 0.22W/(mk), and an energy-saving effect is good; the structural integrity is ensured in flames of 900 DEG C for one hour, and a fireproof effect is good. Building external window parts having a fireproof function and outdoor window curtain parts are perfectly integrated together, various functions of existing building external windows are kept, the fireproof and external sunshade integrated window also has an external sunshadewindow curtain function, and the fireproof function is added.

Description

technical field [0001] The invention belongs to the technical field of building energy saving and fire prevention, and in particular relates to an integrated window for fire prevention and external sunshade. Background technique [0002] In most building structures, such as schools, hospitals, offices, living rooms, etc., in order to prevent summer sunlight from shining indoors. People have adopted the installation of external shading system, divided into fixed external shading and movable external shading. At present, active external shading is widely used, including outdoor louvers, outdoor roller blinds and crank or swing arm awnings. This is to physically block solar radiant heat and sunlight from entering the room through the building envelope. When the sunshade is needed in summer, put it down to prevent sunlight from entering the room, and pull it up in winter to let sunlight enter the room. The energy-saving effect is obvious. Its disadvantages are: affecting the fa...
