Description

Energy-saving plastic-aluminum composite casement doors and windows

Technical field:

The utility model relates to a building door and window, in particular to an energy-saving door and window made of plastic-aluminum composite profiles.

Background technique:

In recent years, the social awareness of energy saving and environmental protection has been strengthened. According to tests, during the heating period in heating areas, the total heat consumption of exterior doors and windows accounts for 41% to 53% of the total building heat consumption. There are still quite a large area in our country that is cold in winter and hot in summer, and building energy conservation is urgent. Energy saving of doors and windows is one of its main measures. At present, most of the common building doors and windows are made of steel, plastic, and aluminum alloy profiles, which are called steel doors and windows, plastic doors and windows, and aluminum alloy doors and windows. , simple process, low cost and other advantages are widely used. With the development of science and technology and the improvement of people's living standards, many new products have emerged in the field of architectural door and window technology, such as steel-plastic composite doors and windows, aluminum-plastic composite doors and windows, and so on. When evaluating these building doors and windows with the five performance index values of wind pressure resistance, air tightness, water tightness, thermal insulation, and air sound insulation performance, the test results show that they all have deficiencies to varying degrees. Steel doors and windows 1. Aluminum alloy doors and windows have high wind pressure resistance, but poor air tightness, thermal insulation and sound insulation performance. Plastic doors and windows have high air tightness, thermal insulation and sound insulation performance, but low wind pressure resistance. Steel-plastic composite doors and windows, aluminum-plastic composite Doors and windows have high wind pressure resistance and airtightness, but low watertightness and thermal insulation. It can be seen from the above analysis that the existing building doors and windows need to be further improved to meet the needs of the people's living standards that are increasing day by day.

Invention content:

The utility model is developed to solve the above-mentioned problems in the technical field of building doors and windows, and aims to provide buildings with energy-saving building doors and windows that meet the above five performance indicators. The technical scheme of the utility model is as follows: a plastic-aluminum composite casement door and window, which is composed of a window frame, a window sash, hollow glass and hardware. The outer surface of the profile used for the frame and sash is foamed hard polyvinyl chloride, and the inner rib is a multi-cavity aluminum alloy profile. The two are compounded and co-extruded. There are three layers of sealing between the window frame and the sash. There is a sealing baffle in the middle of the window frame, and a groove for sealing rubber strips in the middle of the window sash corresponding to it on the window sash. The utility model not only combines the advantages of aluminum alloy doors and windows and plastic doors and windows, but also solves the shortcomings of aluminum alloy doors and windows in terms of air tightness, sound insulation and wind pressure resistance of plastic doors and windows. The multi-cavity aluminum alloy inner ribs are used to make the deformation of the stressed rods small, and the wind pressure resistance of doors and windows is greatly improved; second, the three-layer sealing structure makes the airtight performance, sound insulation performance, watertight performance and thermal insulation performance of doors and windows It is improved, thereby improving the building physical performance of doors and windows.

Description of drawings:

Fig. 1 is the schematic diagram of the sectional structure of the utility model.

Detailed ways:

The main components of the utility model are: sash 1, sash inner rib 2, outdoor sealing strip 3, middle sealing strip 4, window frame 5, window frame inner rib 6, indoor sealing strip 7, switch hardware 8, corner connection Part 9, glass bead 10, insulating glass 11, sash middle seal strip groove 12, corner connector 13 and window frame middle seal baffle 14.

The accompanying drawing shows the cross-sectional structure of energy-saving plastic-aluminum composite casement doors and windows with three-layer sealing function. There are four cavities on the cross-section of the "Z" aluminum alloy inner reinforcement in vinyl chloride, which increases the moment of inertia of the profile and reduces deformation, thereby improving the wind pressure resistance of doors and windows. The four corners of the window sash are respectively connected by corners The part 9 is fixed, and the hollow glass 11 is installed on the window sash. The window sash has three layers of sealing. Glass batten. The window frame 5 is formed by co-extrusion of foamed rigid polyvinyl chloride and aluminum alloy inner reinforcement 6. There are four cavities on the section of the "L"-shaped aluminum alloy inner reinforcement 6, and the four corners of the window frame are respectively connected with corner connectors 13 Fixed, the inner groove on the window frame is provided with a middle sealing baffle 14, and there is a sealing strip corresponding to the middle sealing strip groove 12 of the window sash, and the connection between the window frame and the window sash is assembled into a plastic-aluminum composite interior Casement windows. There are multiple cavities along the longitudinal direction of the aluminum alloy profile on the fishbone-shaped aluminum alloy inner reinforcement section of the sash and window frame, so that this kind of window has good architectural physical properties such as heat preservation, air tightness, and sound insulation, and the overall weight is light. It is easy to manufacture and install, and belongs to energy-saving building doors and windows.

Replacement of standard hardware, the above-mentioned window frame and sash can form inner casement and top-hung doors and windows again.
