The top 10 brands of seismic bracing in China are:SuDian Zhongyuan, Katy, Baolai, Xingyang, Guanlongsen, Optimus Prime, Shihlin, Yideshun, PaiGuGu, Zhongwei. Seismic bracing refers to seismic bracing facilities that are firmly connected to the building structure, with seismic forces as the main load. It consists of anchors, reinforcement booms, seismic connectors and seismic diagonal braces. The significance and role of seismic bracing:Seismic bracing refers to a variety of members or devices that limit the displacement of appurtenant mechanical and electrical engineering facilities, control facility vibration, and transfer loads to the load-bearing structure. Seismic bracing shall provide reliable protection for the building mechanical and electrical engineering facilities during earthquakes and withstand seismic effects from any horizontal direction; seismic bracing shall be calculated according to the loads it is subjected to; all the members composing seismic bracing shall be finished members, and the members connecting the fasteners shall be easy to be installed; the seismic bracing limit of the insulated pipeline shall be designed according to the dimensions of the pipeline after the insulated one, and the displacements caused by the pipeline's thermal expansion and contraction shall not be Restricted. Mechanical and electrical engineering facilities such as water supply and drainage, fire fighting, heating, ventilation, air conditioning, gas, heat, electricity and communication. Seismic reinforcement can reduce earthquake damage, minimize and prevent secondary disasters, thus reducing casualties and property losses.
Domestic manufacturers do a good job mainly have:Hillyard, Jiangsu Senji, Croson, Wolowen, Unicorn, the big brands are the same quality, but the price is certainly not the same, so it is still more than a few comparisons, such as Jiangsu Senji, before the inquiry, the test report is complete, the quality of the package has passed acceptance, the price is fair, and the service is comprehensive.
Seismic hangers can give full protection to the mechanical and electrical systems during earthquakes, and can be used to resist damage from horizontal and vertical seismic forces. According to the different mechanical and electrical systems protected, seismic hangers can be categorized into piping seismic system, duct seismic system and electrical (including electrical conduit, trunking and bridge) seismic system. As we all know, seismic bearings are the materials used in building mechanical and electrical seismic systems. Earthquakes happen every year. Without seismic resistance, buildings are prone to collapse, causing potential safety hazards for people and property. Therefore, it is necessary to attach great importance to building mechanical and electrical seismic resistance. Laying a good foundation for earthquake mitigation has an extremely important role and significance for building seismic mitigation! So how much do you know about seismic bracing? Relevant norms:Seismic brace design basis:According to the "Building Seismic Design Code" GB50011-2010 Article 3.7.1:Non-structural components, including non-structural components of the building and electromechanical equipment attached to the building, should be connected to the main structure in a seismic manner. According to Article 1.0.4 of "Seismic Design Code for Building Electrical and Mechanical Engineering" GB50981-2014:Seismic design is required for building electrical and mechanical engineering facilities in areas with seismic fortification intensity of 6 degrees and above. This specification applies to the seismic design of building mechanical and electrical engineering facilities with seismic intensity of 6 degrees to 9 degrees; it is not applicable to the seismic design of building mechanical and electrical engineering facilities with seismic intensity greater than 9 degrees or with special requirements. Scope of seismic bracing design: 1. DN65 or above domestic water supply, fire-fighting, heating and air-conditioning water piping systems; 2. Suspended piping equipment with gravity greater than 1.8KN or boom with a calculated length of more than 300mm; 3. Electrical piping with an inner diameter of not less than 60mm; 4. Cable ducts, cable trunking and bus ducts with a gravity of not less than 150N/m; 5. Rectangular cross-sectional area of 0.38m2, circular diameter of 0.38m2 or greater; and 5.Rectangular cross-sectional area of 0.38m2, circular diameter of 0.38m2 or greater; and 5. Seismic design of building mechanical and electrical engineering facilities. m2, circular diameter greater than or equal to 0.7m ventilation and air conditioning system; 6. All smoke exhaust ducts, emergency ventilation ducts and related equipment; 7. Gas piping with an internal diameter of not less than 25mm; in buildings with a building height of > 50m, the gas piping should be set up with seismic bracing; 8. Ordinary antennae on the roof and so on. Seismic support installation form:According to the installation form can be divided into single pipe spiral, single pipe seat type, multi-pipe seat type, combined type, etc.. Distribution:Vertical seismic support, transverse seismic support, longitudinal seismic support and so on.
