窗五金配件的分类及用途介绍（Classification and application of window hardware fittings）Introduction: the development of window hardware accessories is closely related to the evolution of window type and window opening mode. The reason for this evolution is the peoples consciousness of window function and the convenience of window usage.Window hardware classificationHardware fittings for sliding windowsThe guide rail of aluminium alloy or plastic steel sliding window is directly formed on the window frame section bar, and the pulley system is fixed at the bottom of the window sash. Whether the sliding of the sliding window is comfortable depends not only on the quality of the pulley system, but also on the flatness of the profile and the machining accuracy and the mounting accuracy of the window frame. The wear and tear of dust on track and pulley will also affect the switch function of sliding window. The lock of the sliding window is usually a latch, which is invalid because of the poor installation accuracy and dust accumulation. The handle of the sliding window is usually replaced by the switch part of the latch type, but also the high-grade sliding window makes the window sash profile arc shaped and plays the role of the handle.Two common casement window hardware fittingsOne of the basic parts of casement window is hinge. Because of the unidirectional opening of the hinge, the hinge is always installed in the opening direction, that is, the inner window and the hinge are arranged indoors, and the outer window opening hinge is arranged outside. In order to prevent the hinge from affecting the sealing of the window, the hinges of the metal window are usually welded outside the window section. The outside window lock is a rotary type of card lock, and the handle is usually combined with the lock phase. The ordinary inner window lock can be a simple bolt. The drawback of the latch is the compression function of the rotary cassette lock. The handle inside the window is independent and does not have any relation with other parts. The limiter is an indispensable part of the outside window to prevent the wind from blowing the window sash and causing collision. However, the fixed level of the two hinges and the limiting device three points is limited, and the good quality limiter is made of copper. The purpose is to prevent rust.Three included inside the casement window hardware accessoriesThe concept of introversion inside the casement window from the form, both suspended and opened, in the open window. But its more than just a special window opening. In fact, its a combination of window control functions. First, when the window is introverted, ventilation. The top shear connector acts as a limiter. When the inside is flat, the top shear connector is a hinge. At the same time the bottom hinge is a shaft with introversion. The purpose of flat opening is to clearly observe the scenery outside the window and, more importantly, to clean the glass easily. The design window type does not consider the cleaning glass. It is the reason why there are few clean and bright windows in the residential buildings in china. It can be said included inside the casement window is the comprehensive satisfaction of the people. Introverted in the casement window hardware includes a top shear connector, corner fittings, lock, handle, connecting rod, multi-point locking, corner connector and introverted window bottom shaft, the bottom hinge and internal rotation shaft bottom. The hardware suitable for wood, plastic steel windows and Aluminum Alloy. How do I fix the connecting rod on the window sash? There are two solutions. First, a pair of connecting rods is designed, one of which is used for fixing, and the other is used for linking the locking points. The second is to design the sliding groove on the window frame section. The second schemes are superior to the first scheme in terms of service life and maintainability.Four glass curtain wall hardware fittingsThe combination of glass curtain wall and window is a difficult problem.The international advanced curtain wall system can be included inside the casement window into a similar glass curtain wall unit, to achieve the overall curtain air tightness, water tightness and wind resistance grade. The technical level and cost of doing so are very high. At present, few domestic companies can reach this level.As the load-bearing structure of the glass curtain wall is generally inside, the window opening is the easiest way to open the window. However, if the hinge is used, the exposed hinge will damage the integrity of the glass curtain wall, so there are four connecting rod fittings. The four link is the substitute of the hinge. It uses the principle of variable area under the condition of constant length of quadrilateral, so as to achieve the purpose of opening the window. The fixing of the four connecting rod is on the side of the window sash and the window frame; when the window is closed, the four connecting rod is completely hidden in the window frame, and the problem of the hinge exposure is fundamentally solved. The only characteristic is determined by the working principle of the four connecting rod, i.e., when the window sash opens, the center of gravity of the sash will have an obvious subsidence. The settlement can prevent the wind from closing the window sash, but brings inconvenience to the installation and use of the window opener. If the form is large, the four connecting rod will bear the weight of the sash for a long time, and it will produce a certain drop, which will cause the window sash to be closed.The use of multi point locks is to increase the strength of the window against wind pressure. A plurality of cylindrical lock points are connected by a connecting rod on the window sash, and the locking point is slid into the lock body fixed on the window frame under the operation of the rotary handle. The corners of the window can be locked with one, two or more locking points by means of corner fittings. The multi point lock completely changed the traditional system of locking windows. The connecting rod locking point scheme is also used to improve the anti-theft level of the door.Five flip window hardware partsThe ordinary reverse window is closed because half of the window sash is opened inside, and the other half window is opened outside. In order to achieve the same sealing effect as the open window or the outside window, the cost of turning the window will be relatively high. The hardware fittings of the common turning window are mainly two rotating shafts, and then they are provided with corresponding locks and handles. Internationally, there is a comprehensive hardware fittings that can be turned 360 degrees. The purpose is to achieve good sealing effect and easy to clean windows at the same time.Six window opener1. manually operated window openerThe purpose of manual window opener is to open the ventilation window with higher position through a certain device. According to the principle of the thermal effect of air, the hot air and light harmful gases should be excluded only through the high position window. Manual window opener generally includes five parts: the window of the implementation of components (such as cut type window), angle connections, operating components, connecting rod and decorative panels. The window executing part determines the width of the window opening, the weight of the window opener and the locking function. The angle joint is a driving component, and its deformation determines the ability of the window opener to adapt to different window types and different installation conditions. The operating parts may be in the form of a handle or rocker. Lever type operation unit is simple, low cost. The utility model has the advantages that the output of the rocker type operation component is even, the damage is not easy to be damaged, the machining accuracy is high, and the cost is higher. Manual window opener is suitable for lower hanging window and hanging window. The outer suspension window shall be equipped with special external opening parts. From the analysis of the force of the window opener, the hinge is located in the lower part of the lower part of the window, and the window opening is comparatively labor-saving.The hinge located in the upper part of the hanging outside the window is relatively easy, especially it should be noted that the four link must be used with caution, because the four rod parts in the window will form the focus of a large settlement is open, if the form of weight to a certain extent, the power window unit may be insufficient to enhance the form will close the window.2. electric window openerThe simplest electric window opener is a mechanical window with an actuator that matches the drive motor and is then coupled with a switch. There are gear rack type window opener and chain window opener. But from the stability and service life of the product, the window opener needs dustproof, moisture-proof and even waterproof. Dust accumulation will cause the window opener to wear out, damp will make the window opener rusty, and water will short-circuit the circuit of the window opener. While indoor relative humidity changes, condensation is a frequent occurrence of buildings with poor heat insulation performance or indoor environment changes, especially greenhouse construction. A thorough and thorough analysis and understanding of the environmental conditions for the use of window opener is essential to the selection of window opener. Internationally closed dust-proof, moisture-proof and waterproof window opener, there is an internal screw window opener. The thrust of the window opener can reach 1000 newtons, and the power consumption is less at the bottom of the noise. Selection of window opener must also pay attention to its installation is convenient, because the construction site installation conditions may be very limited.There are two kinds of automatic control system of electric window opener. Greenhouse control system is based on measured temperature, humidity, sunlight, intensity of the wind, the value of the rain level, and compared with the pre-set value, so as to open windows and closed windows control system.Automatic smoke exhaust and heat evacuation system is a new concept in the world. When the fire happens to produce smoke and heat, the window for smoke exhaust and heat evacuation is automatically opened. Because of the requirement of fire protection for building materials, the fire resistance of materials is precisely defined from the aspect of flame retardancy. Therefore, in case of fire, smoke and harmful substances contained in it cause more direct harm to the personnel. Or harmful smoke, which prevents active life-saving behavior and passive escape behavior. From the study of the development process of fire, it can be seen that at the beginning of fire, a great deal of smoke and heat are produced first. Smoke rises as a result of heat and collects in the upper layer of a building. If the smoke and heat can not be rapidly discharged, the temperature in the building will soon rise, and then increase the fire. In addition, when the fire occurs, the building due to a large number of oxygen consumption, will create a strong negative pressure inside the building, resulting in building collapse. The fact is that fire destroyed buildings, apart from explosive material in the building, usually collapse inward from the top. The automatic smoke exhaust system design, construction and use of company or window and curtain wall production companies, electricity, fire control engineering have been linked to high complexity, the relevant departments of the state should provide system vendor qualification, comprehensive evaluation of customer service experience and service and supervision to ensure the engineering quality. At present, some high-grade buildings have been used in our country.Window hardware useMaybe aluminum alloy was used in the manufacture of windows, and people developed sliding window. The sliding window has no problem with the limiter at all,Because the window sash of the sliding window is basically the same when opened and closed. One of the disadvantages of the sliding window is that it must have at least one fixed fan, which greatly reduces the window area: another fatal weakness is that it does not meet the requirements of tightness and water tightness. The fixing point of the sash of the sliding window is two rails, so the strength of the wind resistance is very limited. Modern buildings are becoming more and more demanding for energy saving and other functions, and they have strict requirements for sealing and heat insulation, air tightness and water tightness, sound insulation, wind resistance, and anti-theft grade of windows. In order to achieve the comprehensive requirements result in inclined casement windows, or European window.The window shape of the modern glass curtain wall is related to the fixing mode of the window frame on the curtain wall. Because the glass curtain wall has higher requirements for air tightness, water tightness and wind resistance, the accessories on the curtain wall and window are relatively independent.The window of modern architecture is not limited to the level that can be reached by hand. The height of window is an important factor to determine the efficiency of heat exchange and ventilation, so people invented various window opener.
