Window hardware accessories classification and usage introduction

A sliding window hardware fittings Aluminium alloy or plastic steel sliding window guides are formed directly on the window frame profile, and the pulley system is fixed at the bottom of the window frame. The sliding of the sliding window is not only dependent on the quality of the pulley system, but also related to the straightness and accuracy of the profile and the precision of the window frame installation. Dust on the track and pulley wear will also affect the sliding window switch function. The lock of the sliding window is generally a bolt type lock, and this kind of lock may fail due to a low installation accuracy, dust accumulation and the like. The handle of the sliding window is usually replaced by the switch part of the plug-type lock, but there are also high-grade sliding windows to make the sash profile an arc type and a pull-up handle.

Two hardware accessories for ordinary casement windows One of the basic accessories for casement windows is the hinge. Due to the one-way opening nature of the hinge, the hinge is always installed in the opening direction, ie, the hinge of the inner window is installed indoors, and the hinge of the outer window is installed outdoors. In order to prevent the hinge from affecting the sealing of the window, the hinge of the metal window is usually welded outside the window profile. The lock of the open window is a rotating card lock, and the handle is usually combined with the lock. Ordinary internal window locks can be simple bolts. The disadvantage of the latch is that there is no compression function of the rotary latch. The handles of the inner windows are independent and have no relation with other parts. The stopper is an essential part of the open window to prevent the wind from blowing the sash and causing a collision. However, the fixed plane formed by the two hinges and the stoppers at three points is limited in strength, and the stoppers of relatively good quality are made of copper for the purpose of preventing rust.

The concept of a three-inside-inside casement window hardware intro-inner casement window is a window that can be suspended from the inside or the inside while being opened in terms of form. But this is far more than a special way of opening windows. In fact, it is a combination of various window control functions. First of all, when the window is introverted, the purpose is to change the air. The top scissor connector acts as a stopper. When the inner plane is open, the top scissor connection is again a hinge. The bottom hinge is also an axis for inward tilting. The purpose of the inner peace is to clearly observe the scenery outside the window, and more importantly, it is easy to clean the glass. The design of windows does not consider cleaning glass as the reason why there are few clean bright windows in low-rise residential buildings in China. It can be said that the introversion casement window is a comprehensive satisfaction for people. The hardware of the inward tilt casement window includes the top shear connector, the upper corner connector, the lock, the handle, the connecting rod, the multi-point lock, the lower corner connector and the bottom axis of the inclining window, and the bottom hinge and the inner bottom shaft. This kind of hardware is suitable for wood, aluminum alloy and plastic steel windows. How to fix the connecting rod on the sash? There are two solutions. The first is to design two sets of connecting rods, one set for fixing and the other set for interlocking lock points. The second is to pre-design the sliding groove on the window frame profile. The second scheme is superior to the first scheme in terms of service life and maintenance-free performance.

Four glass curtain wall window hardware accessories Glass curtain wall and window combination is a more difficult problem. The internationally advanced curtain wall system can create a glass-like curtain wall unit with inward-inside-opening windows to achieve the airtightness, watertightness, and wind pressure rating of the entire curtain wall. The technical level and cost of doing so are high. At present, few companies in the country can reach this level.

Since the load-bearing structure of the glass curtain wall is generally internal, opening the window is the easiest window opening solution. However, if the hinge is used, the exposed hinge will destroy the integrity of the glass curtain wall, so there are four-bar accessories. The four-bar linkage is a substitute for the hinge, which is to use the principle of variable area under the condition that the quadrilateral side length is constant to achieve the goal of opening the window. The fixing of the four-bar linkage is on the side of the sash and the window frame. When the window is closed, the four-bar linkage is completely hidden in the window frame, which fundamentally solves the problem of hinge exposure. The only feature is the phenomenon determined by the working principle of the four-bar linkage, that is, when the window sash is opened, there will be a clear settlement of the sash center of gravity. This settlement can well prevent the wind from closing the sash, but it brings inconvenience to the installation and use of the window opener. If the form is large, the four-bar linkage will bear the weight of the sash for a long period of time, resulting in a certain decrease, which in turn causes the sash to close.

The use of multi-point locks is to increase the wind pressure resistance of the window. A plurality of cylindrical lock points are connected by a connecting rod on the sash. Under the operation of rotating the handle, the lock point slides into the lock body fixed on the window frame. Through the corner connector, all four sides of the window can be locked with one, two or more locking points. Multipoint locks have completely changed the traditional system of locking windows. This link locking solution is also used to increase the door's security rating.

Five flip window hardware fittings Ordinary flip windows Since half of the window sashes are open and the other half of the sashes are open, it is difficult to achieve the seal of the window. To achieve the same sealing effect as purely open or open windows, the cost of flipping the windows is relatively high. The hardware components of ordinary flip windows are mainly two rotary shafts, and are equipped with corresponding locks and handles. Internationally, there is a comprehensive hardware accessory that can be flipped 360 degrees in order to achieve a good sealing effect while also facilitating window cleaning.

6. Window Opener 1. Manual Window Opener The purpose of the manual window opener is to open a higher ventilation window through certain devices. According to the principle of the thermal effect of air, hot air and light harmful gases that should be excluded can be effectively eliminated only through high-position windows. The manual window opener generally includes five parts: an open window execution member (such as a scissor-type window opener), a corner connector, an operating member, a connecting rod, and a decorative cover plate. The window-opening actuator determines the width of the window, the weight of the window lifter, and the locking function. The corner connector is a transmission component whose deformation determines the ability of the window regulator to adapt to different window types and different installation conditions. The operating part can be in the form of a handle or a rocker. Move-in operation components are simple and cost-effective. The power output of the joystick-type operating parts is even and not easily damaged, and the machining accuracy is high and the cost is high. The manual window opener is suitable for the lower hanging inner window and the upper hanging outer window. Suspended windows must be equipped with special external accessories. From the analysis of the force of the window opener, the hinge is located at the lower part of the lower suspension and the internal window is more labor-saving. The hinge is located on the top of the upper hanging window is more difficult, in particular, we must pay attention to the use of four-bar linkage must be cautious, because the four-bar linkage in the window opening will make the center of gravity of the form a larger settlement, if the form To a certain degree of weight, the power of the window opener may not be enough to enhance the form to close the window.

2. Electric window opener The simplest electric window opener is the mechanical window opening actuator with a drive motor and a switch. There are also rack and pinion window openers and chain openers. However, from the perspective of product stability and service life, the window openers need to be dust-proof, moisture-proof and even waterproof. Dust accumulates will cause the window opener to wear out, moisture will cause the window opener to rust, and the water will short circuit the window opener. Condensation caused by changes in indoor relative humidity is often a result of poor thermal insulation of the window or changes in the indoor environment, especially in greenhouse construction. A thorough and thorough analysis and understanding of the environmental conditions used by the window opener is crucial to the choice of window drive. The internationally closed dust-proof, moisture-proof and waterproof window opener has an internal screw type window opener. The thrust of this window opener can reach 1000 Newtons, noise floor, and low power consumption. The selection of the window opener must also pay attention to its ease of installation, because the installation conditions on the construction site may be very limited.

There are currently two types of automatic window opener control systems. Greenhouse control system is based on the measured temperature, humidity, sunlight, the intensity of the wind, the value of the degree of rain, and compared with the preset value, so as to open the window and close the window control system.

The automatic smoke exhaust and heat removal system is a newly developed concept of fire protection in the world. That is, when smoke and heat are generated in a fire, the windows used for exhaust heat are automatically opened. Due to the increasingly comprehensive fire protection requirements for modern building materials, the fire resistance of the material is precisely defined in terms of flame retardancy. Therefore, in the event of a fire, smoke and harmful substances contained in it will cause more direct injury to people. Or that harmful smoke hinders 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 a fire, a large amount of smoke and heat energy are generated first. Smoke rises due to heat and accumulates on the upper floors of buildings. If smoke and heat cannot be expelled quickly, the temperature inside the building will rise quickly and the fire will increase. In addition, when a fire breaks out, a large amount of oxygen is consumed inside the building, causing a strong negative pressure in the building and causing the building to collapse. The fact is that a fire destroyed a building. In addition to the explosive materials in the building, it usually starts from the top and collapses inwards. The design, construction, and use of automatic smoke and heat rejection systems are linked to curtain wall companies or window production companies, weak electricity, and fire control systems. The complexity of the project is high, and the national authorities should provide qualifications, experience, and after-sales services to the manufacturers who provide the systems. Such as comprehensive evaluation and supervision to ensure the quality of the project. At present, some high-end buildings in China have used such systems.

The use of window hardware may be the use of aluminum alloys for the manufacture of windows. People have developed sliding windows. The sliding window has no problem with the stopper at all because the fixed state of the sash of the sliding window when opening and closing is substantially the same. One drawback of the sliding window is that it must have at least one fixed fan, which greatly reduces the window area: Another fatal weakness is the inability to meet hermetic and watertight requirements. Sliding window sash fixed point is the upper and lower two guides, so its wind pressure strength is also very limited. Modern buildings are increasingly demanding for energy-saving and other functions. They have strict requirements for the sealing and heat insulation of windows, airtightness and watertightness, sound insulation and wind resistance, and even the level of theft protection. In order to achieve a variety of integrated requirements, the inward-turning window, or European window, was created.

The window type on the modern glass curtain wall building is related to the fixing method of the window frame on the curtain wall. Due to the high requirements for airtightness, watertightness and wind resistance of glass curtain walls, accessories for curtain wall windows have been developed relatively independently as required.

The windows of modern buildings are not limited to human-accessible levels. Starting from the requirements of ventilation and heat removal, the height of the windows is an important factor in determining the efficiency of ventilation and heat exhaustion, and people have invented various types of window-openers.
