Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a self-resetting friction type three-dimensional shock-absorbing support and hanger for improving the earthquake resistance of building electromechanical engineering. Background Art

[0002] Through the summary of earthquake disasters in previous years, it was found that the damage of non-structural components, such as infill walls, ceiling systems, pipeline systems, elevator systems, etc., is one of the main causes of earthquake losses.

[0003] Among them, damage to the pipeline system is very likely to cause secondary disasters, increasing the difficulty and danger of post-earthquake rescue work. In this regard, the design and use of seismic supports and hangers for pipeline systems can effectively protect building mechanical and electrical engineering facilities during earthquakes to ensure the normal operation of the pipeline system under earthquakes or reduce damage.

[0004] The currently used seismic supports and hangers usually achieve rigid connection by welding, which can easily lead to uneven stiffness distribution and stress concentration at local locations under the action of earthquakes, thereby causing cracks in the seismic supports and hangers and eventually losing their shock-absorbing ability.

[0005] At the same time, most of the current earthquake-resistant supports and hangers can only achieve one-way or two-way earthquake resistance, and the earthquake resistance method generally adopts the contact rotation friction energy dissipation method. Under the above configuration, the earthquake-resistant energy dissipation capacity of the earthquake-resistant supports and hangers is limited, and it is easy to be damaged in rare earthquakes.

[0006] In summary, the current seismic supports and hangers have problems such as single form and limited energy consumption capacity, which greatly reduce the reliability of seismic supports and hangers.

[0007] It can be seen that how to improve the reliability of seismic supports and hangers is a problem that needs to be solved in this field. Summary of the invention

[0008] In view of the technical problem of low reliability of existing seismic supports and hangers, the purpose of the present invention is to provide a self-resetting friction-type three-dimensional shock-absorbing support and hanger, which can effectively reduce the vibration response of the pipeline system under the action of an earthquake, greatly improve the reliability of the seismic supports and hangers, and well overcome the problems existing in the prior art.

[0009] In order to achieve the above-mentioned purpose, the present invention provides a self-resetting friction-type three-dimensional shock-absorbing support hanger, including a plurality of hanger assemblies and an elastic energy-absorbing assembly; the plurality of hanger assemblies are connected by elastic energy-absorbing assemblies, and the elastic energy-absorbing assemblies are used to absorb energy of deformations of different degrees or directions caused by earthquake forces between the plurality of hanger assemblies; the hanger assembly includes a mounting bracket and a friction pair; the friction pair is mounted on the mounting bracket, and the dynamic friction of the friction pair is used to reduce shock to the pipeline arranged on the friction pair.

[0010] Furthermore, the several mounting brackets include several load-bearing suspension rods and several longitudinal horizontal rods; the several load-bearing suspension rods are symmetrically arranged, and the tops of the several load-bearing suspension rods are respectively hinged to the roof fixing point structure through a hinge structure; the bottoms of the several load-bearing suspension rods are hinged to the friction pair through a hinge structure; both ends of the several longitudinal horizontal rods are fixedly connected to the load-bearing suspension rods.

[0011] Furthermore, the friction pair includes a concave plate and a fixed bottom plate; the fixed bottom plate is hinged to the bottoms of the several load-bearing suspension rods through a hinge structure; the concave plate is arranged above the fixed plate and is connected to the longitudinal horizontal rod.

[0012] Furthermore, the upper end face of the fixed bottom plate is coated with a friction coating.

[0013] Furthermore, there are cylindrical holes at the end parts of the two side plates in the concave plate, and the cylindrical holes are arranged through the longitudinal horizontal rod to mount the concave plate on the mounting bracket.

[0014] Furthermore, the bottom plate of the concave plate is coated with a friction coating relative to the end face of the fixed bottom plate, and forms a dynamic friction with the friction coating on the fixed bottom plate.

[0015] Furthermore, the elastic energy dissipation component is an energy dissipation spring, and several hanger assemblies are longitudinally connected along the pipeline through the energy dissipation spring.

[0016] The self-resetting friction type three-dimensional shock-absorbing hanger provided by the present invention uses energy dissipation springs to connect different hanger units, which can ensure that the hanger can flexibly adapt to different building scenarios.

[0017] Secondly, the adopted energy dissipation spring can allow three-dimensional relative deformation between different hanger units, and can also use the spring stiffness to achieve reset after the vibration ends, thereby achieving the effects of three-dimensional shock absorption and self-resetting.

[0018] In addition, the form of the hanger unit can reduce the vibration of the pipeline in the vertical pipeline direction, and at the same time, the setting of the friction pair improves the energy dissipation capacity of the hanger. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0027] Aiming at the technical problem of low reliability existing in the existing seismic hanger supports, based on this technical problem, the present invention provides a self-resetting friction-type three-dimensional shock-absorbing hanger support, which can effectively reduce the vibration response of the pipeline system under earthquake action, and greatly improve the reliability of the seismic hanger support.

[0028] The self-resetting friction-type three-dimensional shock-absorbing hanger support provided by the present invention is shown in Figure 1 , and includes a hanger support assembly 100 and an elastic energy dissipation component 200.

[0029] Among them, there are at least two groups of hanger support assemblies 100, which are connected by an elastic energy dissipation component 200 to form the self-resetting friction-type three-dimensional shock-absorbing hanger support in this solution.

[0030] As shown in Figure 2 , each hanger support assembly 100 includes an installation bracket 110 and a friction pair 120.

[0031] Among them, as shown in Figure 3 , the installation bracket 110 includes four load-bearing suspension rods 111 and two longitudinal horizontal rods 112.

[0032] Among them, the four load-bearing suspension rods 111 are symmetrically arranged, and hinge holes are respectively provided at the top and bottom of each load-bearing suspension rod 111, and fixing holes are also provided on the load-bearing suspension rod 111.

[0033] The top of the load-bearing suspension rod 111 is connected to the structural roof fixing point 400 through a hinge structure 130 fitted in the hinge hole, and the top of the load-bearing suspension rod 111 can rotate relative to the structural roof fixing point 400 along the hinge structure.

[0034] The bottom of the load-bearing suspension rod 111 is hinged to the friction pair 120 through a hinge structure 140 fitted in the hinge hole, realizing the movable connection between the load-bearing suspension rod 111 and the friction pair 120, and the load-bearing suspension rod 111 and the friction pair 120 can rotate relative to each other.

[0035] Two longitudinal horizontal rods 112 are respectively arranged on two load-bearing suspension rods 111, and both sides of the longitudinal horizontal rod 112 are fitted with the fixing holes of the load-bearing suspension rod 111 through fixing parts 150 to fixedly connect the longitudinal horizontal rod 112 and the load-bearing suspension rod 111.

[0036] In this solution, see Figure 4 , one end of the load-bearing suspension rod 111 is hinged to the structural roof fixing point 400, and the other end is hinged to the friction pair 120. On the basis of this connection, in any cross-section perpendicular to the pipeline 300, a parallelogram is formed among the structural roof fixing point 400, any two load-bearing suspension rods 111 and the friction pair 120, and the support hanger assembly 100 can realize free deformation in the direction perpendicular to the pipeline.

[0037] At the same time, the load-bearing suspension rod 111 is hinged to the structural roof fixing point 400, and after the earthquake ends, it can be automatically reset due to its own gravity.

[0038] In this solution, it is not limited to using four load-bearing suspension rods 111 and two longitudinal horizontal rods 112, and the specific quantity selection can be determined according to the actual situation.

[0039] Furthermore, the friction pair 120 includes a concave plate 160 and a fixed bottom plate 170.

[0040] The fixed bottom plate 170 is hinged to the bottoms of several load-bearing suspension rods 111 through a hinge structure 140; see Figure 5 , at the same time, the upper end surface of the fixed bottom plate 170 is coated with a friction coating 171, which is fitted with the contact surface of the concave plate 160, and friction energy dissipation can be realized.

[0041] Furthermore, the concave plate 160 is composed of three connecting plates, namely a bottom plate 161 and two side plates 162, and a plate with a concave-shaped structure can be formed by connecting the three connecting plates.

[0042] There are cylindrical holes at the end parts of the two side plates 162 in the concave plate 160. Passing the longitudinal horizontal rod 112 through the cylindrical holes will realize the suspension connection, and this suspension connection can reduce the deformation of the pipeline 300 in the out-of-plane direction.

[0043] Meanwhile, through the hanging connection, after the earthquake ends, the friction pair 120 can automatically reset by its own gravity.

[0044] See Figure 5 , the concave plate 160 corresponds to the friction coating 171 on the fixed bottom plate 170, and the friction coating 163 is coated on the lower end surface of the concave plate.

[0045] When the concave plate 160 and the fixed bottom plate 170 are in the normal state, the friction coating 163 at the bottom of the concave plate 160 does not directly contact the friction coating 171 on the fixed bottom plate 170, and there is a gap in the middle.

[0046] However, when under the action of the earthquake, when the fixed bottom plate 170 deforms relative to the load-bearing suspension rod 111, the friction coating 171 on the fixed bottom plate 170 contacts and generates friction with the friction coating 163 on the concave plate 160, dissipates energy through dynamic friction, reduces the earthquake action transmitted to the pipeline 300, and achieves the shock absorption effect.

[0047] By respectively coating the friction coating 163 and the friction coating 171 on the concave plate 160 and the fixed bottom plate 170, it is possible to achieve low starting slip force and ensure a certain energy dissipation capacity.

[0048] The friction coating 163 and the friction coating 171 here can be a high friction coefficient coating and a low friction coefficient coating respectively.

[0049] Meanwhile, the setting schemes for the high friction coefficient coating and the low friction coefficient coating are not limited here. The high friction coefficient coating can be set on the fixed bottom plate 170, and the low friction coefficient coating can be set on the concave plate 160. Similarly, it can also be set in the opposite way; the selection of the specific setting scheme can be determined according to the actual situation.

[0050] Meanwhile, due to the different stiffness of different parts of the structure itself, it is easy to cause different degrees or directions of deformation of the hanger assemblies 100 installed in different parts. Therefore, in this scheme, elastic energy dissipation components 200 are arranged to connect between each hanger assembly 100.

[0051] The elastic energy dissipation component 200 in this scheme is an energy dissipation spring, and several hanger assemblies 100 are longitudinally connected along the pipeline 300 through the energy dissipation spring.

[0052] By using the energy dissipation spring, when the hanger assemblies 100 deform, the energy dissipation spring also deforms. When the energy dissipation spring deforms, it can dissipate seismic energy and reduce the influence of seismic force on the pipeline 300.

[0053] Secondly, the energy-dissipating spring can utilize its own deformation ability to achieve relative displacements of different support and hanger assemblies 100 in three-dimensional directions.

[0054] In addition, after the earthquake, the elastic restoring force of the energy-dissipating spring can also be used for automatic resetting.

[0055] The length of the energy-dissipating spring here is not limited and can be determined according to the pipeline 300's route. When the pipeline 300's route is straight, energy-dissipating springs of equal length can be used. If the pipeline 300's route is curved, energy-dissipating springs of different lengths can be used to adapt to the curved structure of the pipeline, so that the shock absorption effect can be maintained at the best, thereby achieving the function of adapting to different building forms.

[0056] The following is an example to illustrate the working process of this solution in specific applications. It should be noted that the following content is only a specific application example of this solution and does not limit this solution or specific functions.

[0057] Fix this three-dimensional shock-absorbing support to the upper structure through the structural roof fixing point 400, and pass the pipeline 300 through several support and hanger assemblies 100 and place it on the friction pair 120.

[0058] When an earthquake comes, different inertial forces are generated at different parts of the support and hanger. Since the fixed bottom plate 170 and the load-bearing hanging rod 111 are hinged, and the load-bearing hanging rod 111 and the structural roof fixing point 400 are hinged, the fixed bottom plate 170 and the load-bearing hanging rod 111 will produce displacement and deformation relative to the concave plate 160. At the same time, since the concave plate 160 is hung on the longitudinal horizontal rod 112, under its own gravity, the displacement generated by the concave plate 160 is less than the displacement generated by the fixed bottom plate 170.

[0059] During the displacement process of the fixed bottom plate 170, the high-friction coefficient coating 171 on the fixed bottom plate 170 is in direct contact with the low-friction coefficient coating 163 of the concave plate 160 and generates relative friction, so that the low-friction coefficient coating 163 and the high-friction coefficient coating 171 dissipate energy through friction, reducing the seismic action transmitted to the pipeline 300.

[0060] When the load-bearing hanging rod 111 generates deformations of different degrees or directions, the energy-dissipating spring 200 can utilize its own deformation ability to achieve relative displacements of different support and hanger assemblies 100 in three-dimensional directions, and dissipate seismic energy by generating deformations, reducing the influence of seismic force on the pipeline 300.

[0061] After the seismic action ends, under the action of gravity, the support and hanger assembly 100 of the shock-absorbing support can utilize the hinged connection between the load-bearing hanging rod 111 and the structural roof fixing point 400, and the hanging connection between the concave plate 160 and the longitudinal horizontal rod 112 to achieve the function of self-resetting.

[0062] Meanwhile, since the energy-dissipating spring 200 itself has a certain stiffness, it can achieve self-resetting of the relative positions between different hanger assemblies 100.

[0063] The self-resetting friction-type three-dimensional shock-absorbing hanger formed by the above solution is different from the design with the same cross-section of any section of the traditional shock-absorbing hanger along the pipeline direction. In the present invention, energy-dissipating springs are used to connect different hanger units, which can ensure that the hanger can flexibly adapt to different building scenarios;

[0064] Meanwhile, the energy-dissipating springs adopted in the present invention can allow three-dimensional relative deformation between different hanger units, and at the same time, the spring stiffness can be used to achieve resetting after the vibration ends, thereby achieving the effects of three-dimensional shock absorption and self-resetting;

[0065] Secondly, the form of the hanger unit in the present invention can reduce the vibration of the pipeline in the vertical pipeline direction, and at the same time, the setting of the friction pair improves the energy-dissipating capacity of the hanger.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
