Doors and windows are regarded as the eyes of the building and are an important part of the building. It not only provides rich decorative effects to the building facade, but also plays an important role in controlling the energy consumption of the building. And hardware accessories, is known as the heart of doors and windows! It can be said that the life of doors and windows is determined by the hardware. Have you chosen the right one? Please follow Mtuosi's door and window hardware system editor to learn about:
1. In addition to the physical and mechanical properties of doors and windows, what other conditions should they meet?
(1) Easy to operate, single-point control: realize various opening functions by changing the position of the handle;
(2) Standardization and serialization, so that door and window enterprises and construction companies can be installed quickly;
(3) Adjustability;
(4) Strong bearing capacity;
(5) High security;
(6) Widely used;
(7) Strong applicability (high quality specifications).
2, how to choose and design door and window hardware accessories?
(1) When selecting hardware accessories, try to choose products with guaranteed quality. The quality grade of hardware accessories should be consistent with the quality grade of doors and windows. The structure and shape of hardware accessories should be consistent with the profile, the colors are beautiful, the functions are correct, Flexible operation and easy installation.
(2) The installation of hardware accessories should be complete, standardized, secure and accurate. After installation, the doors and windows are beautiful in appearance, flexible and convenient to open, and there must be no deformation, obstruction or collision.
(3) Stainless steel products are preferred for exposed fasteners of hardware accessories.
(4) Multi-lock points should be adopted when closing casement doors and large sliding doors and windows, otherwise the air tightness will be greatly reduced under the negative pressure difference. Considering the convenience of operation, it is best to use multi-lock point handles or actuators .
3. How wide is the sash of a casement window?
What are the disadvantages of installing an oversized sash? Some owners like large sashes. They think that the ventilation effect is good. In fact, the larger and smaller sashes are not much different. And what are the disadvantages of sash over the assembly? First, the sash is too heavy and increases the load of accessories such as sliding braces, hinges, hinges, etc., which increases friction, shortens the service life of accessories, and increases the resistance to opening and closing. The second is that the stroke of the handle lock increases when the sash is opened and closed, requiring more arms to extend, which will also increase the difficulty of opening and closing and increase the danger.
Generally, the width of the sash is 60-65 cm. Some owners want to be 75 cm wide.
4. How high is the handle position for doors and windows?
The position of the casement window handle lock is best explained when ordering, in order to adjust parameters in design and processing, after all, it is customized according to the specific circumstances of the owner. How suitable is the position of the handle lock? The male owner of 1.8 meters in height likes to be taller. When designing, he should know the height of the female owner. If the height is 1.5-1.6 meters, it is even shorter to wear slippers at home. , The lock is high, and it is inconvenient for the female owner to open and close the sash, especially when the sash is opened to a large angle, the body of the female owner needs to be protruded out of the window, which is not only laborious and dangerous. But too low is not suitable for male owners.
Under normal circumstances, the height of the handle lock off the ground should be near the shoulder position of the female owner, usually about 1.4 meters. If the female owner is relatively tall, adjust it upward.
5. The sliding brace with poor quality will loosen after being used for a period of time, which will seriously cause the sash to fall off and cause hidden safety hazards. What are the requirements for high-quality sliding braces?
Sliding braces must be rust-proof, because if rust will affect the smoothness of sliding, and reduce the mechanical properties of sliding braces, it will cause fracture. To have good rust resistance, high grade stainless steel materials such as 304 stainless steel should be selected. Such stainless steels have high corrosion resistance and high strength and toughness, while low grade stainless steels such as 201 and 202 Although the price is low, the rust resistance is lower than that of the 300 series. And 304 stainless steel has higher wear resistance.
In addition, the thickness of the sliding brace also affects the bearing capacity. When the sash is heavy, it is best to choose a sliding brace with a thickness of 2.5 or more.
6. Why does the hinge show grease after a period of time?
After a period of operation of the hinge, the viscosity of the added grease decreases, and it is easier to flow out. At the same time, the shaft core and the reel of the hinge will cause different degrees of wear. When the wear is more serious, more black iron powder will be produced. Oil is blackened. Therefore, depending on the oil used and the processing accuracy, greased hinges will have transparent or black grease flowing out sooner or later, which will affect the appearance to varying degrees.
7. Which "five" gold is often referred to as door and window hardware?
①Building door lock: A lock installed on the door and frame of a building that needs to be opened and closed. It is generally composed of lock body (including lock tongue, door and window hardware, operating mechanism and braking mechanism), lock panel, handle, cover plate and so on. The lock tongue is divided into oblique tongue, square tongue, double tongue, bead tongue and hook tongue. The lock panel is divided into flat mouth, left tongue, right tongue and round mouth, and the handle has a spherical shape, curved handle and Pull the ring apart. Architectural door locks can be divided into door locks, room door locks, bathroom door locks, windproof door locks and toilet door locks according to the occasion of use. According to the insurance performance, they can be divided into single insurance, double insurance and triple insurance door locks. Divided into exterior door locks, mortise door locks and spherical door locks.
②Handle: used to open and close the metal sash. Generally installed in the middle of the edge of the window sash, and some are also designed as a mechanism that connects the door and window hardware with the latch. It is usually made of brass, low carbon steel, zinc alloy, stainless steel and other materials, and its surface is plated with nickel, chromium or zinc.
③ support: used to position the opened metal sash. Generally installed on the lower edge of the sash, and some are also designed to be used in conjunction with the hinge. It is usually made of brass, low carbon steel, zinc alloy, stainless steel and other materials, and its surface is plated with nickel, chromium or zinc. Varieties include eye support, double arm support, rocking support, mobile support and so on.
④ Hinge: Also called hinge. It is the connection between door and door frame, window and window frame, which can make door and window rotate freely to open and close door and window hardware. The hinge is made up of blades and pins. The blade is made of low-carbon strip steel, which can rotate freely around the pin shaft. The pin is made of low-carbon cold-drawn steel wire or spring steel wire. Hinge varieties include common hinges, spring hinges and window hinges.
⑤ Door closer: An appliance that can automatically close or fix an open door leaf in a certain position. Some have the function of hinges, and some have fire resistance. The main varieties are floor springs, door top springs, door slingshots, door controllers, door chucks and magnetic door suction heads.
8. How to properly maintain the door and window hardware for a longer life?
①Stainless steel handles and other stainless steel "hardware" can be scrubbed with a brightener to increase brightness.
②Hanging parts such as hinges, hanging wheels, casters, etc. may reduce their function due to the adhesion of dust during long-term movement. Put one or two drops of lubricant every six months to keep them smooth.
③ Pay special attention to the direction of rotation of the handle, and avoid using dead force. In particular, children should be taught not to sway from the door handle, which is dangerous and may cause damage to the inner door. Once the lock is broken, the house is basically unguarded, and the security risks are very large!
④ When the lock core is not sensitive enough to rotate, you can scrape a small amount of black powder from the pencil core and blow it gently into the lock hole. This is because the graphite composition is an excellent solid lubricant. Do not drip into the lubricant, as it will more easily adhere to dust.
9. Why can the door and window hardware affect the economic performance of the door and window and the life of the whole window?
There is also fierce market competition in the building door and window industry. One of the important ways to get rid of single price competition and create a benign market environment is to continuously enrich product functions and expand product profitability with technological advantages. The important link that can enrich the functions of doors and windows is hardware accessories.
The quality of hardware also affects the life of doors and windows. Good hardware should look thick, and the surface gloss should be good, the protective layer should be dense, and there should be no scratches. The most important point is that it should be flexible to open.
10. Why is the persistence of the physical properties of doors and windows directly related to the structure and performance of hardware?
After the casement revolving window entered China's building doors and windows industry, due to its good physical and use properties, this window type has gradually been accepted by the Chinese.
The test results prove that the airtightness and watertightness of the building doors and windows that use casement flip hardware can reach the national standard level one. At present, the structure of such hardware and profile systems used in China's door and window industry is mostly the same as the current European system. Its characteristics are that in addition to the four sides of the sash can be locked at the same time, the hardware system can achieve three-dimensional adjustment of the sash relative to the window frame, to ensure that the performance of the doors and windows is at its best.
