The overall design of the building owes much attention to the characteristics of the five aluminum alloy doors and windows using plastic doors and windows hardware aluminum doors and windows hardware: 1, easy to operate, a single point of control. Various open functions are achieved by changing the position of the handle handle; 2. Standardization and serialization. Make door and window manufacturers and construction companies able to install quickly; 3, adjustability. With multi-position adjustable function; if no special requirements, all hardware can be installed either left-open window or right-open window; 4, strong bearing capacity. Can meet the sash maximum weight 130kg; 5, high installation. The barb can be hooked on the lock block on the window frame; 6. It is widely used. Can meet the various opening requirements of doors and windows; 7, adaptability. Can be used on the current market with a standard European groove profile or without groove; 8, high quality specifications. The base body is made of zinc-aluminum alloy die-cast parts and the surface is plated or sprayed. Some parts are corrosion-resistant stainless steel or cast PA66.
Aluminum alloy doors and windows of the cross-section structural design problems Aluminum alloy doors and windows to achieve excellent wind pressure performance, air tightness, watertight performance and thermal insulation properties, in the aluminum alloy door and window profiles cross-section structural design, consider the following Aspects: 1. Steel strength, strength and moment of inertia of the profile; 2. Design of thermal insulation structure of the profile; 3. Installation structure and activity space of the hardware; 4. Reasonable sealing structure design; 5. Door and window frame and wall Reasonable sealing and corresponding profile structure; 6. Opening requirements of doors and windows on the main profile and auxiliary profile structure requirements; 7. A reasonable layer structure; 8. Drainage structure design.
In actual projects, due to the unreasonable design of aluminum alloy door and window profiles, the performance of aluminum alloy doors and windows is reduced. Common errors include the following: 1. The design of the profile does not consider the installation structure of the hardware. The space is caused by the unreasonable design of the profile. After the lock is finished, the design of the door profile to be milled is unreasonable. 2. In the structural design of watertightness and airtightness, the size of the cross-section of the profile is not good, and the amount of lap joints is not enough, causing the sash to leak.
In the structural design of aluminum alloy doors and windows, the design of the heat-dissipation location is irrational. After the hardware is installed, the aluminum profile of the broken bridge is continuously hot. Broken Bridge Insulated aluminum bridge not broken 7, door and window assembly, installation of existing problems Eight, choose a reasonable hardware to meet the use of aluminum alloy doors and windows with the progress of science and technology and people's living standards, the requirements of doors and windows function Is also gradually increased, such as the requirements of door and window hardware to meet the wind and pressure performance of doors and windows, airtight performance, watertightness, etc., but also have: 1, easy to operate, a single point of control, doors and windows open diversification; 2, a good appearance Decorative effect, the main hardware and more hidden in the aluminum door and window profile structure; 3, strong bearing capacity, can be made larger, heavier opening fan; 4, has a good anti-theft performance; 5, anti-misoperation function, prevent Due to erroneous operation, damage to doors, windows and hardware; 6, standardization, serialization, and perfection; 7. Good reliability and long life.
However, in the project, despite the selection of good aluminum doors and windows hardware, due to the lack of matching hardware, there have also been some incomplete projects. High-rise building casement window hardware configuration is not uniform, the internal flat open window hardware configuration is not reasonable The entire window only uses the hinge, wind bracing, seven-word handle; only a single lock and seven-word handle and window The frame lock is to slot the frame.
Especially with the emergence of microprocessors and the continuous improvement of industrial automation technology, load cells have become a necessary device in process control.
From the weight measurement of large tanks and hoppers that could not be weighed before, and the measurement and control of crane scales, automobile scales, etc., to the batching system for mixing and distributing a variety of raw materials, automatic detection in the production process, and control of the powder and granular material feed volume, etc., Have applied the load cell.
At present, load cells are mainly used in various electronic weighing instruments, industrial control fields, online control, installation overload alarms, material testing machines, and other fields, such as electronic truck scales, electronic platform scales, electronic forklifts, dynamic axle load scales, electronic hook scales, etc., Electronic pricing scales, electronic steel scales, electronic rail scales, hopper scales, batching scales, filling scales, etc.
load cell for hopper scales, load cell for industrial use, load cell for automatic detection
