Promote domestic fire door innovation

As for the fire security door, are you familiar with it? It must be used in our lives, yes, today, we want to introduce to you the effect of its use, I will take everyone to see what magical effect it has, see if it is people The specific reason for love.

In its use, some problems will arise: the fire door is generally latched or locked: some local doors are locked for a long time to simply plug the private device on the door or lock the fire door with a general lock. I usually pay attention to the use of fire doors: everyone pushes the door hard when the general revenue is completely exported, and even the foot door fire door can not properly seal the door. That is, the door device is re-solid, and unreasonable use will also fail. Private line decoration: Its primary function is fire prevention, so there is a shortage in the beautiful role, especially the wooden door can be described as ugly, so some people have modified the door after the fire part inspection, there is a brush If the paint has a decorative panel, it is a question of whether the data used is flammable. In the modification, the internal fireproof data is damaged, and the fireproof sealing strip is cracked, which will affect the fireproof function of the door.     There are a large number of doors, windows and hardware accessories enterprises in China, but most of them are small-scale, low-concentration and backward equipment, and they are still small-scale production enterprises. It is difficult to form a system concept that needs to be resolved.

At present, China urgently needs to improve the performance and production process of doors and windows, and integrate with the international community as soon as possible. This requires improving the technical level of the door and window hardware accessories as soon as possible. In terms of concept, it is necessary to raise awareness and raise the supporting position of the hardware accessories in the hearts of the people to the important position as soon as possible. Only in this way can we really improve the performance and function of doors and windows.

The real technology is in the system workers supporting the doors and windows

Door and window hardware accessories are both static and dynamic, and must be met at the same time, which has essentially determined the delicateness of the door and window technology.

At many exhibitions, we saw many famous companies' doors and windows, the appearance is quite good, electrophoretic aluminum, and even fluorocarbon sprayed aluminum, equipped with insulating glass, colorful, diverse styles, but the opening is not flexible, the shaking is large, the configuration is not reasonable. This is the result of not paying attention to hardware.

So what kind of functions should real door and window hardware have? In addition to meeting the physical and mechanical properties of doors and windows, the following conditions must be met:

First, it is easy to operate, single point control, to achieve various opening functions by changing the position of the handle of the handle; second, standardization and serialization, enabling door and window enterprises and construction companies to install quickly; third is adjustability; fourth is load-bearing Strong; five is high security; six is ​​widely used; seven is strong applicability, high quality specifications.

In order to ensure the excellent quality of doors and windows, high-grade door and window hardware is basically made of precision molds and high degree of automation. The materials are mainly made of stainless steel, aluminum alloy, zinc alloy and high quality engineering plastics under the premise of strength. Some factories used plain carbon steel to make it cheap, and it started to rust in a few months. What's more, only one interest, the material and configuration are changed at will, leaving serious security risks to the doors and windows.

When high-precision hardware is combined with high-precision profiles, it does not necessarily result in a good door and window. The combination of good hardware and good profiles is the result of the door and window company making great efforts in system engineering design and production, and coordination with all relevant parties, especially hardware accessories.

There are many times when we often hear people complain that doors and windows are so inflexible, just blaming hardware accessories. However, other problems are neglected, such as the quality of the strip, the quality of the profile, the accuracy of the notch (such as the size of the notch should be the size after surface treatment), the processing accuracy of the group angle, and the like.

The quality of doors and windows is determined by a series of complete quality assurance systems. The production of doors and windows must pay attention to the system engineering of each production link, especially to fundamentally change the contempt for hardware accessories.

Door and window hardware accessories are capital and technology-intensive industries in the developed countries in the West, while in China, there are generally insufficient funds and weak technology, which still belong to labor-intensive industries.

This gap between China and the developed countries of door and window hardware is shrinking. With the improvement of living conditions for Chinese people, the demand for door and window hardware will become larger and larger, and it will develop to a higher level. The development of door and window hardware is vast, and people are constantly pursuing higher quality and higher quality doors and windows, which provides endless imagination for the development of hardware. We can only design and develop high-quality, high-grade hardware in accordance with the development direction of the market, in order to push the door and window industry to one peak.

As a large public place for fire in a large public place, it is extremely important to carry out self-maintenance and reduce the extension of fire. Because the launch of the product is controlled by electric power, the power cord of the product is Laying is a certain standard. The power line and control line of the product are equally important. When the line is selected as a dark coating, the demand should be laid in the structural layer of the non-combustion body. The maintenance thickness should not be less than 30mm. In public buildings such as large shopping malls, if the number of fire doors per floor is large, the power supply should be divided into several circuits: one is to reduce the diameter of the embedded pipe, and the other is to reduce the power supply. Metal hoses should be used for the control box to the motor and to the limiter. Best to wear heat or fire resistant wires. The flashing motor, the limiter and the rolling door are integrated, and there is a groove for lifting the shutter door on the ceiling below the roller shutter. This groove will cause the fire to enter the ceiling, and the wire of the motor and the stopper is helium, so The best choice is heat resistant wire or fire resistant wire. The wires of the linkage control box are also laid in the ceiling with a heat-resistant wire through a metal hose, and are best laid close to the floor. The manual control box is directly embedded in the wall, and the threading tube is also embedded in the column or in the wall, which is usually sufficient for satisfactory fire resistance. But a section of the line leading to the control box is inside the ceiling. Therefore, it is necessary to use a heat-resistant wire to lay through a metal hose. In all the installation process, the laying of all power lines is very important, so when laying, we need to abide by the relevant standards to avoid the formation of the appearance of the product in the event of a fire, which will form a serious result.
