In recent years, China's frequent earthquakes have had a great impact on economic development and social production. With the research and progress of seismic technology, China pays more and more attention to the seismic performance of engineering buildings. The emergence and development of seismic support has gradually become the most common kind of modern building construction, most prominently in power construction, So what should we pay attention to in the construction of electrical engineering? The seismic support is important to transmit the seismic action to the building structure through the connection with the base, and has a strong bearing capacity. Therefore, in the design drawing, it should be reasonably arranged according to the layout of the building and electrical lines, which must be executable and reasonable. During direct installation, workers shall strictly follow the design drawings to ensure the correct position of seismic support, so as to ensure the quality of electrical wiring installation works.
As a supplier of seismic support products, we pay more attention to seismic support. Although the frequency of earthquakes in China is by no means high, earthquakes are a serious threat to people's lives and property. Therefore, we must not ignore the earthquake. At present, with the progress of science and technology, many earthquake resistant products are also rapidly improving. It is because of the use of these earthquake resistant products that the casualties and property losses of earthquake resistance are also reduced. Well, speaking of this, many friends who are interested in earthquake resistance will have some questions. What is the role of those earthquake resistant products in earthquake? Then the above Xiaobian will introduce in detail the role of earthquake resistant supports in earthquake resistance.
The seismic support is important to transmit the seismic action to the building structure through the connection with the base, and has strong bearing capacity. Therefore, when designing the drawings, it should be reasonably arranged according to the layout of the building and electrical lines, which must be executable and reasonable. During direct installation, workers shall strictly follow the design drawings to ensure the correct position of seismic support, so as to ensure the quality of electrical wiring installation works. The comprehensive support and hanger of seismic support is to integrate the support and hanger of strong current, air conditioning, fire protection and other disciplines in the installation project, make overall planning and design, and integrate them into a unified support and hanger system.
Therefore, on the basis of high-performance earthquake resistance of the building body, the earthquake resistance of electromechanical equipment must be implemented. The use of seismic support is a reliable guarantee for the earthquake resistance of electromechanical equipment There is no need for welding and drilling during the installation of seismic support It can be easily disassembled, modified and adjusted. The disassembled accessories and channel steel can be reused, resulting in less waste of materials. The seismic support has good compatibility, and a total of one hanger can be used by each discipline; Can make full use of space, so that the professional pipeline can be well coordinated The installation speed of seismic support is 3 ~ 5 times that of traditional support, and the manufacturing and installation cost is half of that of traditional support On the premise of meeting the management specifications, various disciplines and types of work can be cross operated to greatly improve the work efficiency and shorten the installation period of supports and hangers.
What is the relationship between seismic support, load-bearing support, pipe gallery support and finished support? As explained above, finished support is a complete and installable support product. Therefore, whether it is seismic support, load-bearing support or pipe gallery support and fire support, if they meet the condition of "complete and installable support product", they all belong to "finished support". In a broad sense, seismic, load-bearing, pipe gallery and other supports have the traditional practice of non-finished products, especially the load-bearing support and pipe gallery support, most of which are still used in construction; At present, most of the seismic supports are made in the way of finished products, which can be installed on the construction site and can be adapted to the traditional supports and hangers. This is why many practitioners confuse seismic supports with finished supports.
The support form of seismic support equipment can also be divided into lateral support and longitudinal support, which are divided according to the function. Lateral support is mainly used to resist the lateral horizontal seismic force, and longitudinal support is also used to resist the longitudinal force. At present, FM certification is the most authoritative organization for seismic testing in the world. Seismic supports and hangers have very strict requirements on the performance of diagonal braces, especially the design of connecting seats at both ends of diagonal braces must be reasonable. The angle between diagonal braces and vertical suspenders also needs to be within the specified range, and the angle has a certain impact on the force range that seismic supports and hangers can bear.
