Description

Technical Field

[0001] This invention belongs to the field of seismic bracing technology for building electromechanical systems, and specifically relates to a seismic support for disaster mitigation. Background Technology

[0002] In the current "Code for Seismic Design of Building Mechanical and Electrical Engineering" GB50981-2014 (hereinafter referred to as the "Code for Seismic Design of Mechanical and Electrical Engineering"), the "seismic bracing" is an additional support system installed by drilling holes in the beams, slabs, and columns of the building structure after the traditional supports are installed in the mechanical and electrical systems (such as pipes, cable trays, busbars, air ducts, etc.). By increasing lateral, longitudinal, and vertical support, it strengthens the constraints in the X, Y, and Z directions, forming a multi-stage statically indeterminate structure, and provides seismic fortification for various professional mechanical and electrical systems, reducing the damage of earthquakes to mechanical and electrical systems, preventing sudden destruction of mechanical and electrical systems by earthquakes, and achieving the seismic fortification objectives stipulated in Article 1.0.3 of the "Code for Seismic Design of Mechanical and Electrical Engineering".

[0003] However, the installation of "seismic bracing" can easily damage the building structure and concealed pipelines during drilling, and can also cause the electromechanical system and the building structure to resonate at the same frequency. In practice, the electromechanical facilities are fixed by traditional brackets, which is equivalent to the two ends being hinged to form four constraints (belonging to a statically indeterminate structure). After adding "seismic bracing" in the middle (which is statically indeterminate multiple times), the electromechanical facilities and seismic bracing cannot deform freely and play their seismic role, resulting in an insignificant earthquake prevention and disaster reduction effect. Summary of the Invention

[0004] The purpose of this invention is to provide a seismic support to address the shortcomings and deficiencies of existing seismic bracing systems, such as potential damage to building structures and concealed pipelines during installation, and the tendency for electromechanical systems and building structures to resonate at the same frequency after installation. This invention also enhances the seismic resistance and disaster reduction function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An earthquake-resistant and disaster-mitigating support is installed between a traditional support and an electromechanical system. It includes a support, a vertical disaster-mitigating damper, a lateral disaster-mitigating damper, and a clamping assembly that is fitted and tightened around the electromechanical system. Supports are provided on both sides of the clamping assembly, and vertically extending lateral columns are provided on the supports. The lower end of the support is fixedly connected to the traditional support. Vertical and lateral disaster-mitigating dampers are connected to both sides of the clamping assembly. The end of the vertical disaster-mitigating damper furthest from the clamping assembly is connected to the traditional support or a corresponding support, and the end of the lateral disaster-mitigating damper furthest from the clamping assembly is connected to a corresponding lateral column.

[0006] As a preferred technical solution of the present invention, the lower end of the support is provided with a horizontally extending support base plate, which is connected to the conventional bracket by a first bolt.

[0007] As a preferred technical solution of the present invention, the upper end of the vertical disaster mitigation damper is fixedly connected to a first screw rod, and the first screw rod is positioned on the clamp assembly by a first nut.

[0008] As a preferred technical solution of the present invention, the number of vertical disaster mitigation dampers and the number of lateral disaster mitigation dampers are both greater than or equal to two. Both ends of the clamp assembly are connected to force transmission plates. The middle part of the force transmission plate is fixedly connected to the clamp assembly through a force transmission rod. Both ends of the force transmission plate can be detachably connected to vertical disaster mitigation dampers and lateral disaster mitigation dampers.

[0009] As a preferred technical solution of the present invention, the force transmission rod is threadedly connected with clamping nuts that respectively cooperate with the clamping assembly and the force transmission plate to clamp it. The two ends of the force transmission plate are horizontal connecting parts. The first screw passes through the horizontal connecting parts, and the lower end of the horizontal connecting part abuts against the first nut threadedly connected to the first screw.

[0010] As a preferred technical solution of the present invention, the end of the vertical disaster mitigation damper away from the clamp assembly is connected to a traditional bracket or corresponding support by a third bolt.

[0011] As a preferred technical solution of the present invention, both ends of the clamp assembly are provided with upwardly extending vertical connecting plates, the lateral disaster mitigation damper is disposed between the vertical connecting plates and the lateral column, the other end of the lateral disaster mitigation damper is provided with a second screw, the second screw passes through the vertical connecting plate, and the side of the vertical connecting plate near the lateral disaster mitigation damper is abutted by a second nut threadedly connected to the second screw.

[0012] As a preferred technical solution of the present invention, one end of the lateral disaster mitigation damper is fixed to the lateral column by a fourth bolt.

[0013] As a preferred technical solution of the present invention, the vertical disaster mitigation damper is a hydraulic damper or a spring damper with fixed plates connected to both ends; the lateral disaster mitigation damper is a hydraulic damper or a spring damper with fixed plates connected to both ends; the elastic extension range of both the vertical disaster mitigation damper and the lateral disaster mitigation damper is between 8-10mm.

[0014] As a preferred technical solution of the present invention, the clamp assembly includes two semi-circular clamps, the middle of which are matched and clamped to the outside of the electromechanical system. Both ends of the two semi-circular clamps are provided with side connecting plates, and the side connecting plates at both ends of the two semi-circular clamps are detachably connected. The other end of the vertical disaster mitigation damper and the other end of the lateral disaster mitigation damper are both connected to the side connecting plates.

[0015] Beneficial effects: During installation, this invention is directly installed between the traditional support and the electromechanical system, eliminating the need for drilling holes in the beams, slabs, and columns of the building structure to install additional supports. It also eliminates the need for additional constraints between the traditional supports for plumbing pipes, electrical cable trays, busbars, ventilation systems, and other electromechanical facilities. In practice, the use of vertical and lateral damping devices allows for quantitative deformation of the electromechanical system, achieving seismic fortification goals. This avoids the defects caused by drilling holes in the structure to install seismic supports, which can damage the structure and concealed pipelines. It can reduce the structural dead load in the design calculation (ignoring the weight of the supports themselves) and change the resonance characteristics between the electromechanical engineering support system and the building structure. The damping characteristics can overcome the consumption of seismic energy and appropriately reduce the amplitude of the building during major earthquakes, which is conducive to achieving seismic fortification goals and plays a positive role in "proactive prevention" of earthquake disasters. It can completely replace the seismic function of the existing "seismic supports" for electromechanical engineering systems and can further reduce the probability of disasters to the building structure during major earthquakes.

Detailed Implementation

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0019] Example: like Figure 1 and Figure 2 As shown, this embodiment provides a seismic and disaster mitigation support, installed on the traditional support 1 and the electromechanical system 2 ( Figure 1(Taking a pipe or duct as an example) Between them, there are supports 3, vertical disaster dampers 4, lateral disaster dampers 5, and clamping components 6 that are matched and tightened outside the electromechanical system 2. The clamping components 6 are conventional clamping structures, except that the middle part of the clamp can be an arc-shaped structure or a square structure, depending on the actual situation. For example, when it is for a pipe or a circular duct, the middle part of the clamp can be a matching arc-shaped mechanism, and when it is for a cable tray, busbar trunking, or rectangular duct, the middle part of the clamp can be a matching rectangular structure, so that the clamping components 6 can be matched and tightened outside the electromechanical system 2.

[0020] Both sides of the clamp assembly 6 are provided with supports 3, and vertically extending lateral columns 301 are provided on the supports 3. The lateral columns 301 can be columnar or plate-shaped structures, without specific restrictions. The lateral columns 301 have a side parallel to the extension direction of the electromechanical system 2, which is used to connect the lateral disaster mitigation damper 5. The lower end of the support 3 is fixedly connected to the traditional bracket 1. The stability of the support 3 and the vertical disaster mitigation damper 4 and the lateral disaster mitigation damper 5 installed on and connected to the support 3 are ensured by the traditional bracket 1. Specifically, both sides of the clamp assembly 6 are connected to vertical dampers 4 and lateral dampers 5. The extension direction of the lateral dampers 5 is perpendicular to the extension direction of the electromechanical system 2, which is used to reduce the amplitude of the vibration of the electromechanical system 2 to both sides. The end of the vertical damper 4 away from the clamp assembly 6 is connected to the traditional support 1 or the corresponding support 3 to ensure the stability of the vertical damper 4. The end of the lateral damper 5 away from the clamp assembly 6 is connected to the corresponding lateral column 301 to ensure the stability of the lateral damper 5. Thus, the vertical dampers 4 and lateral dampers 5 limit the electromechanical system 2 in the vertical and horizontal directions to achieve the purpose of earthquake resistance.

[0021] In practical applications, when an earthquake occurs, the energy released by the earthquake is transferred through the building structure to the traditional supports fixed to the structure, and then to the seismic damping supports fixed to the traditional supports. Lateral damping devices 5 and vertical damping devices 4 are installed on the supports 3. The damping devices preferably have an elastic expansion range of 8-10mm, meaning they are designed as limiting devices that can compress or extend 8-10mm. Under the corresponding seismic fortification intensity, the ultimate displacement must meet the seismic design verification requirements specified in Articles 3.4.5, 3.4.7, 3.5.1, and 3.5.2 of the "Code for Seismic Design of Mechanical and Electrical Systems" GB50981-2014, ensuring that the ultimate displacement of the elastic deformation of the mechanical and electrical system 2, the vertical damping device 4, and the lateral damping device 5 is within the calculation. The damping devices overcome the resistance of the mechanical and electrical system 2 (pipes, cable trays, busbars, air ducts, etc.). The resistance generated by inertia, when an earthquake greater than the design intensity occurs, the disaster mitigation damper continuously absorbs and dissipates the seismic impact energy, preventing excessive elastic deformation of the electromechanical system and the damper. The remaining seismic energy and force are transferred between the building structure and the electromechanical system by the disaster mitigation damper, protecting the electromechanical system 2, achieving the seismic fortification target of the electromechanical system, and realizing the function of earthquake prevention and disaster reduction. Because it is installed on the traditional support 1, rather than on the building structure, there is no need to drill holes in the structure, which can overcome the defect of damage to the structure and concealed pipelines caused by drilling holes in the structure for installing seismic supports. It can reduce the structural load in the design settlement (ignoring the weight of the support itself) and change the resonance characteristics of the electromechanical engineering support system and the building structure. It can use the damping characteristics to overcome the dissipation of seismic energy and appropriately reduce the amplitude of the building during a major earthquake, playing a certain degree of earthquake prevention and disaster reduction role.

[0022] During installation, this invention is directly installed between the traditional support 1 and the electromechanical system 2, eliminating the need for drilling holes in the building's structural beams, slabs, and columns to install additional supports. It also eliminates the need for additional constraints between the traditional support 1 and water pipes, electrical cable trays, ventilation systems, and other electromechanical facilities. In practice, the vertical damping device 4 and the lateral damping device 5 allow for a fixed amount of deformation in the electromechanical system 2, achieving the seismic fortification target of Article 1.0.3 of the "Code for Seismic Design of Electromechanical Systems" (GB50981-2014). This avoids the defects caused by drilling holes in the structure for installing seismic supports, which can damage the structure and concealed pipelines, and reduces the structural design calculations required. By applying constant loads (ignoring the weight of the supports themselves) and altering the resonance characteristics between the electromechanical engineering support system and the building structure, the damping characteristics can be used to overcome the consumption of seismic energy and appropriately reduce the amplitude of the building during major earthquakes. This is beneficial to achieving the seismic fortification goal of Article 1.0.1, Paragraph 3 of the "Code for Seismic Design of Buildings" (GB50011-2010), which states that "the building will not collapse or suffer serious damage that endangers life when affected by rare earthquakes." This plays a positive role in "proactive prevention" of earthquake disaster prevention and mitigation, and can completely replace the seismic function of the current "seismic bracing" for electromechanical engineering systems. It can also reduce the probability of disasters to the building structure caused by major earthquakes to a certain extent.

[0023] After installing the existing seismic bracing: Representative value of gravity load at each floor elevation = (M 楼面、梁 +m 墙柱 +m 楼面活载 +m 机电 )g Among them, M 楼面、梁 Each mass point must include the mass of the floor slab and beams on that floor; m 墙柱 Each layer of mass must include the mass of the upper and lower half of the walls and columns; m 楼面活载 Each mass point must include the mass of the live load on that floor. m 机电 The mass of each floor must include the mass of the electromechanical systems installed under the floor slab and beams of that floor; g is the acceleration due to gravity.

[0024] After installing the new type of seismic-resistant and disaster-reducing bearing, its damping technology delays the action of electromechanical engineering resistance, causing the force to become negative due to its opposite direction to the seismic force. Therefore, the calculated gravity load value in the seismic design of the structure can be reduced (at least to provide a safety margin for the seismic design). Representative gravity load value at each floor level = (M 楼面、梁 +m 墙柱 +m 楼面活载 -m 机电 )g, where the meanings of each parameter are the same as in the above formula.

[0025] In the event of a major earthquake, removing the mechanical and electrical systems from a building before it collapses is of great significance for achieving the seismic fortification target of Article 1.0.1 of the Code for Seismic Design of Buildings (GB50011-2010) in terms of earthquake prevention and disaster reduction.

[0026] As a preferred embodiment of this example, it should be further explained that the lower end of the support 3 is provided with a horizontally extending support base plate 302, which is connected to the traditional support 1 by a first bolt. The end of the vertical disaster mitigation damper 4 away from the clamp assembly 6 is connected to the corresponding support 3. This makes it easier and more stable to install the support 3 on the traditional support 1, and facilitates subsequent loading and unloading operations according to the actual situation.

[0027] As a preferred embodiment of this example, it should be further explained that the upper end of the vertical disaster mitigation damper 4 is fixedly connected to a first screw 401. When there is only one vertical disaster mitigation damper 4 on one side of the clamp assembly 6, the first screw is preferably positioned on the clamp assembly 6 by a first nut. The clamp assembly 6 has an installation through hole that matches the first screw 401, so that the first screw 401 can pass through the installation through hole. The vertical disaster mitigation damper 4 and the clamp assembly 6 are fastened by tightening the first nut. Of course, the two ends of the clamp assembly 6 are fixed by bolts and nuts. Therefore, the two ends of the clamp assembly 6 are also designed with through holes for installation. The first screw 401 can pass through the first screw 401 and be used as a bolt for fixing the clamp assembly 6. It can be fixed with the nut. This design allows the connection between the vertical disaster mitigation damper 4 and the clamp assembly 6, as well as the fixing of the clamp assembly 6 itself, to share the same set of screw and nut structure. This not only reduces the number of parts and the complexity of installation, but also ensures the tightness and reliability of the connection, avoiding installation errors and potential loosening risks caused by multiple sets of fasteners.

[0028] As a preferred embodiment of this practice, it should be further noted that the number of vertical disaster mitigation dampers 4 and the number of lateral disaster mitigation dampers 5 are both greater than or equal to two. Both ends of the clamp assembly 6 are connected to force transmission plates 7, and the middle of the force transmission plate 7 is fixedly connected to the clamp assembly 6 via a force transmission rod 8. For example... Figure 2As shown (it should be noted that, based on the combination of gravity load and seismic load and the installation space of the electromechanical system, 1, 2, 4, 6, 8, 10, ..., 2n vertical disaster mitigation dampers can be installed at both ends of the clamp assembly, and similarly, the number of lateral disaster mitigation dampers can also be set to 1, 2, 4, 6, 8, 10, ..., 2n). Both ends of the force transmission plate 7 can be detachably connected to vertical disaster mitigation dampers 4 and lateral disaster mitigation dampers 5, and the installation configuration can be selected according to the actual situation, for example... Figure 1 When only one lateral damper 5 is installed, it is preferably installed on the vertical connecting plate; when two or more lateral dampers 5 are installed, it is preferably installed on the force transmission plate 7. The force transmission plate 7 is preferably made of high-quality carbon structural steel, integrally stamped, and its thickness is precisely calculated to ensure that no plastic deformation occurs under combined seismic loads, thereby ensuring the stability and reliability of vertical force transmission. At both ends of the force transmission plate 7, there are oblong holes that match the second screw of the vertical damper 4. The design of the oblong holes allows for a certain range of fine-tuning of the position of the vertical damper 4 during installation, so as to better adapt to actual installation errors and structural stress requirements. After the second screw of the vertical damper 4 passes through the oblong holes of the force transmission plate 7, it is preferably locked and fixed by double nuts. The anti-loosening design of the double nuts can effectively prevent the nuts from loosening under long-term vibration environment, further ensuring the reliability of the connection between the vertical damper 4 and the force transmission plate 7. Based on the combination of electromechanical system weight load and seismic load, as well as the actual installation space, the model and quantity of disaster mitigation dampers are scientifically configured to ensure the overall earthquake resistance and disaster mitigation performance of this product.

[0029] As a preferred embodiment of this invention, it should be further noted that the force transmission rod 8 is threadedly connected with clamping nuts that respectively engage with the clamping assembly 6 and the force transmission plate 7 to clamp them together. Figure 2 As shown, the two ends of the force transmission plate 7 are horizontal connecting parts. The first screw 401 passes through the horizontal connecting parts, and the lower end of the horizontal connecting part abuts against the first nut threaded onto the first screw 401. Preferably, the preload and elastic deformation of the elastic washer further enhance the anti-loosening effect of the nut connection, ensuring that the vertical disaster mitigation damper 4 maintains a stable installation position and working state during long-term use. Of course, the upper end of the horizontal connecting part can also be provided with the first nut threaded onto the first screw 401 to further enhance structural stability. The vibration generated during an actual earthquake is transmitted to the support 3 of the present invention. The support 3 of the present invention evenly distributes the vibration to the vertical disaster mitigation damper 4 and the lateral disaster mitigation damper 5. After being damped by the vertical disaster mitigation damper 4 and the lateral disaster mitigation damper 5, the vibration is transmitted to the force transmission plate 7, and then to the clamp assembly 6 through the force transmission rod 8, ultimately achieving a vibration damping effect on the electromechanical system 2.

[0030] As a preferred embodiment of this example, it should be further explained that the end of the vertical disaster mitigation damper 4 away from the clamp assembly 6 is connected to the traditional support 1 or the corresponding support 3 by a third bolt, which facilitates the installation and removal of the vertical disaster mitigation damper 4, while ensuring the stability of the vertical disaster mitigation damper 4, so as to deal with the bolt loosening problem that may occur in the support under long-term vibration environment, and ensure that the vertical disaster mitigation damper 4 can continuously and stably transmit and dissipate vertical seismic energy.

[0031] As a preferred embodiment of this invention, it should be further explained that both ends of the clamp assembly 6 are provided with upwardly extending vertical connecting plates. The lateral disaster mitigation damper 5 is disposed between the vertical connecting plates and the lateral column 301. The other end of the lateral disaster mitigation damper 5 is provided with a second screw 501, which passes through the vertical connecting plate. A second nut threaded onto the second screw 501 is abutted on the side of the vertical connecting plate near the lateral disaster mitigation damper 5. By tightening and loosening the second nut, the installation preload of the lateral disaster mitigation damper 5 can be easily adjusted to ensure that it can respond quickly and play a damping role during an earthquake. Of course, in practice, a second nut threaded onto the second screw 501 can also be provided on the other side of the vertical connecting plate. The vertical connecting plate is clamped by the second screws 501 on both sides to further enhance the stability of the structure. When the number of lateral disaster mitigation dampers is ≥2, both ends of the clamp assembly 6 are connected and fixed through the force transmission rod 8, the middle part of the force transmission plate 7 is fixedly connected to the force transmission rod 8, and both ends of the force transmission plate 7 are detachably connected to the lateral disaster mitigation damper 5.

[0032] As a preferred embodiment of this invention, it should be further explained that one end of the lateral disaster mitigation damper 5 is fixed to the lateral column 301 by a fourth bolt, which facilitates the installation and removal of the lateral disaster mitigation damper 5 and ensures the stability of the vertical lateral disaster mitigation damper 5. This is to address the bolt loosening problem that may occur in the support under long-term vibration environment and ensure that the lateral disaster mitigation damper 5 can continuously and stably transmit and dissipate lateral seismic energy.

[0033] As a preferred embodiment of this invention, it should be further explained that the vertical disaster mitigation damper 4 is a hydraulic damper or a spring damper with fixed plates connected to both ends; the lateral disaster mitigation damper 5 is a hydraulic damper or a spring damper with fixed plates connected to both ends. When the vertical disaster mitigation damper 4 is a hydraulic damper, it is filled with high-viscosity hydraulic oil. Through the reciprocating motion of the piston in the cylinder, the viscous resistance generated when the hydraulic oil passes through the damping hole is used to dissipate vertical seismic energy, which has the characteristics of fast response speed and stable damping force. If a spring damper with fixed plates connected to both ends is selected, the energy can be absorbed and released through the elastic deformation of the spring. The structure is simple and the cost is low. The setting of the fixed plate can ensure that the spring maintains a stable axial compression or tension state during the force process and avoid lateral displacement. Similarly, if the lateral damper 5 is a hydraulic damper, its working principle is similar to that of the vertical hydraulic damper, which can effectively dissipate the horizontal seismic impact force; while when a spring damper with a fixed plate is selected, the fixed plate can evenly transmit the lateral force to the spring, so that the spring produces elastic deformation in the horizontal direction to buffer the vibration. Both types of dampers can be flexibly selected according to the actual engineering needs to adapt to the earthquake prevention and disaster reduction requirements in different scenarios.

[0034] As a preferred embodiment of this example, it should be further explained that the clamp assembly 6 includes two semi-circular clamps, the middle of which are fitted and clamped to the outside of the electromechanical system 2. Both ends of the two semi-circular clamps are provided with side connecting plates, which are detachably connected. The other end of the vertical disaster mitigation damper 4 and the other end of the lateral disaster mitigation damper 5 are connected to the side connecting plates. The inner sidewalls of the two semi-circular clamps can be adaptively designed according to the outer circumference shape of the electromechanical system 2. For example, when the electromechanical system 2 is cylindrical, the inner sidewall of the clamp is set as an arc-shaped surface that matches the outer circumference of the cylinder to ensure a tight fit with the outer surface of the electromechanical system 2 and improve the clamping effect. The side connecting plate has mounting through holes. The side connecting plates of the two semi-circular clamps are detachably connected by bolts and nuts passing through the mounting through holes. This connection method not only facilitates installation and disassembly, making it convenient to inspect or replace the electromechanical system 2, but also allows adjustment of the clamping force on the electromechanical system 2 by adjusting the tightness of the bolts, ensuring the stability of the connection between the clamp assembly 6 and the electromechanical system 2 under different working conditions.

[0035] The following section provides examples illustrating the application scenarios of the earthquake-resistant and disaster-mitigation bearing in this invention: (1) Application Case Scenario I: In new construction projects, seismic mitigation supports can be installed on traditional supports of electromechanical engineering systems, eliminating the need for seismic bracing. This achieves the seismic fortification target of the electromechanical system, reduces the damage to the structure caused by installing seismic bracing, reduces the weight of building structural calculations, decreases the amplitude of building vibration under earthquake action, and improves the seismic efficiency of the building structure. (2) Application Case Scenario II: In areas with seismic fortification intensity of 6 degrees or higher, for old buildings constructed before the publication of the "Code for Seismic Resistance Design of Mechanical and Electrical Systems" (GB50981-2014) that did not have seismic fortification of mechanical and electrical systems, seismic-resistant and disaster-mitigation supports can be added to the existing traditional supports of the mechanical and electrical systems. This can not only achieve the seismic fortification target of the mechanical and electrical systems and eliminate seismic energy, but also reduce the quality of seismic design calculations for building structures, avoid resonance between mechanical and electrical systems and disaster-mitigation structures, reduce the amplitude of building vibration under seismic action, improve the seismic efficiency of old buildings, and play a proactive role in seismic resistance and disaster mitigation of building structures.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
