Multifunctional sections and door and window made of the sections

Abstract

The sections include Type A hinge section, Type B hinge section, Type C hollow hinge pin, Type D sealing section, Type F1 rack section, Type H fixing and connecting section, Type AC combined hinge section, and Type BC combined hinge section. Combining the section and accessories can form different structure of doors and windows for various applications. The combined doors and windows have good hermeticity, reliability, assembly property and decoration function and is suitable for various buildings.

Description

technical field [0001] The invention relates to a multifunctional profile and a door and window thereof, which are mainly used in houses and buildings, in particular to a multifunctional profile for making doors and windows and doors and windows made of the multifunctional profile. Background technique [0002] The materials used for doors and windows change with the times and regions, from low-level to advanced materials. In modern times, doors and windows are mainly made of wood, wood plus glass, steel, steel plus glass, plastic (synthetic material), plastic (synthetic material) plus glass, modern commercial and decorative doors and windows have been developed to use glass doors and windows, plus on the metal fittings. After the 1980s, due to the production of standardized aluminum alloy profiles, aluminum alloy profile doors and windows have been widely used in home decoration and business. Stainless steel doors and windows are also developing. [0003] In addition to ...

AI Technical Summary

Problems solved by technology

[0007] (1) The current aluminum alloy doors and windows are basically opened and closed by sliding the doors and windows on the slide rails. Generally, the opening degree of the finished doors and windows does not exceed half of the area of ​​the doors and windows. Such a structure causes insufficient indoor lighting and air pollution. poor circulation;

[0008] (2) Due to the characteristics of the current aluminum alloy profiles, the radius of the slide rail and the pulley groove is small, which causes the sliding friction of the door and window on the door (window) track to be large, the sliding is uncomfortable, and there is a large noise when moving. The pulley is made of iron. , easy to rust, high replacement frequency;

[0009] (3) The aluminum profile is low in strength and easy to deform. When it is stressed or due to strong wind, the deformed doors and windows will shake, especially the life of aluminum alloy windows (including sealing materials) in high-rise buildings and the strength of the material. Building aluminum alloy glass curtain walls can cause accidental injuries. At present, a series of problems arising from this are also the focus of public attention;

[0010] (4) For the aluminum alloy doors and windows currently designed and manufactured, the door and window cores can be easily removed from the outside of the track (outdoor lower part), resulting in poor safety of the doors and windows

Therefore, some users who have installed aluminum alloy windows also require the installation of steel anti-theft guardrails to prevent theft, which increases the user's investment accordingly. Such a design looks very unsightly from the outside of the house, and does not meet the relevant national fire protection requirements;

[0011] (5) The structural characteristics of the slide rail profile in the aluminum alloy profile are easy to form a hygienic dead angle, especially the down slide rail. Dust, mud, etc. are accumulated on the down slide rail, which is difficult to clean. It will also affect the sliding of door and window cores. When aluminum alloy doors and windows are used indoors for room partitions, the sliding rail of the door forms a threshold, which also brings inconvenience to the overall cleaning and walking of the room.
