Description
Technical Field
The utility model relates to a hinge field, concretely relates to prevent falling location sliding support.
Background
At present, the safety problem of 'falling prevention' of the outward opening window is a core problem which is troubled in the door and window curtain wall industry, and the problem of inward opening or outward opening of the door and window is very entangled when the door and window specification is made in various provinces and cities. The existing opening methods of doors and windows are divided into three categories:
sliding window
The advantages are that: the anti-falling hidden trouble is eliminated, the use is convenient, the indoor space is not occupied, the indoor vision is transparent, and the ventilation requirement can be met.
The disadvantages are as follows: the sound insulation performance is poor, and the air tightness, the water tightness and the heat insulation performance cannot meet the use requirements, and particularly, rainwater backflow hidden dangers are easily generated in coastal cities and high-rise buildings in rainy days, so that the urban buildings are gradually eliminated.
Inward opening window (with inward opening and inward reversing window)
The advantages are that: the hidden trouble of falling prevention and transparent indoor vision are eliminated, and the requirements of sound insulation, heat insulation and heat preservation can be met.
The disadvantages are as follows: the hidden trouble of water leakage exists, and the use requirement cannot be met; the curtain occupies more indoor space when being opened, has the potential safety hazard that children easily collide with, and the inward-falling opening can not meet the ventilation requirement, and directly influences the installation and use of the curtain. Particularly, in coastal cities and high-rise buildings, the drainage quantity of doors and windows is limited in heavy weather, so that the hidden danger of water leakage is easily caused, and therefore, the hidden danger of water leakage is generally not adopted in urban buildings (except that in some cities, compulsory execution of the inward opening window specification which is not made into tables and is not made into books is carried out).
Outward opening window (known as flat-open window)
The advantages are that: the indoor vision is transparent, the requirements of sound insulation, heat preservation, air tightness, water tightness and ventilation can be met, the hidden danger of water leakage is eliminated, and the wind and rain prevention requirement under severe weather is met. The casement window with the invisible screen window installing function developed at present meets the use requirements of people on doors and windows, so that the outward opening window is commonly adopted in buildings in various cities.
The disadvantages are as follows: the high-rise opening fan has the hidden danger of falling, and the policy that the anti-falling device must be installed on the high-rise outward-opening window is provided for solving the hidden danger of falling. The solution is that a steel wire safety rope is used for hanging after the window sash falls. In fact, the method is also a measure for treating symptoms but not root causes. The local use function of the outward opening window is influenced. The problem of preventing the window sash from falling off cannot be solved. But only has the function of a safety rope.
