Description

Technical Field

[0001] This utility model relates to the field of ceiling suspension technology, and in particular to a flexible stress-relieving and earthquake-resistant suspension rod. Background Technology

[0002] In the field of suspended ceiling engineering, traditional suspended ceiling structures mainly rely on rigid connections such as ordinary hangers, bolts, or welding to fix the ceiling panels to the building structure. This connection method lacks buffering and energy absorption mechanisms when facing dynamic loads such as earthquakes, strong winds, or uneven settlement of the building structure, easily leading to safety hazards. With the improvement of building safety standards and the increasing demand for seismic performance in high-rise and public buildings, the research and development of seismic-resistant ceiling technology has become a key focus in the industry.

[0003] In existing technologies, vertical hangers are mostly made of ordinary steel or aluminum alloy. One end is fixed to the main building structure, such as the floor slab, by bolts or welding, while the other end connects to the ceiling joists or panels. Some solutions use telescopic hangers with built-in springs or rubber pads to achieve limited elastic deformation, but elastic elements are prone to fatigue failure and have limited energy absorption capacity, making it difficult to cope with high-frequency, large-amplitude vibrations. Common connectors include rigid angle brackets, hinged joints, or sliding sleeves. Rigid angle brackets can fix the hanger to the joists, hinged joints allow the hanger to rotate within a certain angle, and sliding sleeves allow the hanger to slide slightly through a reserved gap to relieve stress. However, their rotation or sliding range is limited, and during earthquakes or severe building shaking, it is impossible to adjust the stress state of the hanger in a timely and flexible manner according to the complex vibration direction, which can easily lead to local stress concentration in the ceiling. Horizontal supports are mostly ordinary steel or aluminum alloy beams, with some using truss structures to enhance lateral stiffness.

[0004] Under normal conditions, these solutions ensure the stability of the ceiling under static loads through rigid or semi-rigid connections. When vibration occurs, the elastic elements of the telescopic hangers absorb energy through stretching or compression, while hinged joints and sliding sleeves allow the hangers to rotate or displace slightly to release stress. In some solutions, energy-dissipating components such as rubber damping blocks can also help absorb vibration energy, thereby improving the seismic resistance of the ceiling structure to a certain extent.

[0005] Existing seismic design schemes suffer from poor coordination among components. For example, energy-consuming components like added rubber damping blocks in some schemes struggle to form an efficient working mechanism with hangers and connectors, failing to effectively disperse vibration energy. Under prolonged and frequent vibration, elastic elements and hinge points are prone to fatigue fracture or loosening, leading to decreased seismic performance of the ceiling and increased maintenance costs. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a flexible stress-relieving seismic-resistant hanger. Through the connection relationship and collaborative working mechanism between the vertical hanger, the horizontal alloy steel, and special connectors, the special connectors possess flexible rotation characteristics, allowing the horizontal alloy steel connected to the vertical hanger to rotate and displace flexibly under normal conditions. When encountering an earthquake or severe shaking, the vertical hanger can absorb and disperse vibration energy, and the special connectors can flexibly rotate and displace according to the vibration direction, promptly adjusting the stress state of the vertical hanger. The cooperation of these three components enables the ceiling to dynamically adjust the stress during vibration, avoiding structural damage and further enhancing the seismic resistance effect, thus achieving effective protection of the ceiling structure under different working conditions.

[0007] To achieve the above objectives, this utility model provides a flexible stress-relieving and seismic-resistant hanger, comprising: a special connector, a vertical hanger, and a horizontal alloy steel.

[0008] The special connector adopts a column structure, and a through fixing hole is provided on the special connector along the axial direction. The diameter of the through fixing hole matches the diameter of the transverse alloy steel. The special connector is set horizontally.

[0009] The vertical suspension rod is set vertically, and a through connection hole is opened radially at the bottom. The diameter of the through connection hole matches the diameter of the horizontal alloy steel.

[0011] In the above technical solution, preferably, the special connector has open slots above its two ends, and the two vertical rods are respectively connected to the open slots at both ends of the special connector.

[0012] In the above technical solution, preferably, the flexible stress-relieving and seismic-resistant hanger also includes a connecting rod. The upper part of the connecting rod has a through-connecting hole in the radial direction. The special connector has an open groove in the lower middle part. The upper end of the connecting rod is inserted into the open groove in the lower middle part of the special connector. At the same time, the transverse alloy steel is inserted into the through-connecting hole of the connecting rod. The lower end of the connecting rod is fixed to the ceiling keel.

[0013] In the above technical solution, preferably, the special connector has two parallel through-fixing holes. The opening direction of the open slot is such that when the vertical rod is inserted into the open slot, the through-connecting hole at the bottom of the vertical rod corresponds to the through-fixing hole at the top. One horizontal alloy steel is inserted into the through-fixing hole and the through-connecting hole of the vertical rod. When the connecting rod is inserted into the open slot, the through-connecting hole of the connecting rod corresponds to the through-fixing hole at the bottom. Another horizontal alloy steel is inserted into the through-fixing hole and the through-connecting hole of the connecting rod.

[0014] In the above technical solution, preferably, the vertical suspension rod is an alloy steel cylindrical rod, and the vertical suspension rod has an elastic modulus along the axial direction.

[0015] In the above technical solution, preferably, the transverse alloy steels are spaced 80cm apart.

[0016] In the above technical solution, preferably, the diameter of the vertical rod is at least 15 mm.

[0017] In the above technical solution, preferably, damping pads are provided in the through fixing hole and the open groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: through the connection relationship and collaborative working mechanism between the vertical hanger, the horizontal alloy steel, and the special connector, the special connector has flexible rotation characteristics, which allows the horizontal alloy steel connected to the vertical hanger to rotate flexibly under normal conditions.

The cooperation of the three enables the ceiling to dynamically adjust the stress during vibration, avoid structural damage, further enhance the seismic resistance, and achieve effective protection of the ceiling structure under different working conditions.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings:

[0027] like Figures 1 to 4 As shown, a flexible stress-relieving and seismic-resistant hanger provided by this utility model includes: a special connector 3, a vertical hanger 1, and a horizontal alloy steel 2;

[0028] The special connector 3 adopts a column structure. A through fixing hole 31 is provided on the special connector 3 along the axial direction. The diameter of the through fixing hole 31 matches the diameter of the transverse alloy steel 2. The special connector 3 is set horizontally.

[0029] The vertical hanger 1 is set vertically, and a through connection hole is opened radially at the bottom. The diameter of the through connection hole matches the diameter of the horizontal alloy steel 2.

[0030] The special connector 3 has an open groove 32 along the radial direction. The top of the vertical hanger 1 is fixed inside the building wall 4, and the bottom is inserted into the open groove 32. The horizontal alloy steel 2 is inserted into the through fixing hole 31 and simultaneously inserted into the through connection hole.

[0031] In this embodiment, through the connection relationship and collaborative working mechanism between the vertical hanger 1, the horizontal alloy steel 2, and the special connector 3, the special connector 3 has flexible rotation characteristics, allowing the horizontal alloy steel 2 connected to the vertical hanger 1 to rotate flexibly under normal conditions. When encountering an earthquake or severe shaking, the vertical hanger 1 can absorb and disperse the vibration energy, and the special connector 3 can rotate flexibly according to the vibration direction, adjusting the stress state of the vertical hanger 1 in a timely manner. The cooperation of the three enables the ceiling to dynamically adjust the stress during vibration, avoiding structural damage, further enhancing the seismic resistance, and achieving effective protection of the ceiling structure under different working conditions.

[0032] Among them, the special connector 3, as a connecting component, mainly relies on a specific connection structure to allow the vertical rod 1 and the horizontal alloy steel 2 to achieve flexible rotation and displacement within a limited range after the connection is completed. Its internal structure is designed with a connection structure adapted to the vertical rod 1 and the horizontal alloy steel 2, providing sufficient space and necessary conditions for relative movement between the two. The special connector 3 itself does not possess the ability to actively rotate and displace in multiple directions; it primarily acts as a connecting medium, enabling the vertical rod 1 and the horizontal alloy steel 2 to achieve flexible rotation and displacement through this connector.

[0033] Specifically, the top of the vertical hanger 1 is connected to special hardware structures such as ceiling joists and building main embedded parts by means of bolt fastening or welding to ensure the stability of the connection.

[0034] The horizontal alloy steel 2 can be a cylindrical high-strength alloy component, arranged horizontally in the ceiling structure. Its function is to connect multiple vertical hangers 1, thereby forming a stable support system. Due to its high strength, the horizontal alloy steel 2 can evenly distribute the force transmitted from the vertical hangers 1, greatly enhancing the stability of the entire ceiling structure. Moreover, when vibration occurs, it can work in conjunction with the vertical hangers 1 to jointly resist the impact of external forces.

[0035] In the above embodiments, preferably, the vertical rod 1 is a high-strength alloy steel cylindrical rod, and the vertical rod 1 has an elastic modulus along the axial direction.

[0036] Specifically, high-strength alloy steel has excellent toughness and tensile properties, which can ensure that the suspension rod will not easily deform or break when subjected to large tensile forces, thus laying a solid foundation for subsequent absorption of vibration energy.

[0037] In the above embodiment, preferably, open slots 32 are provided above both ends of the special connector 3, and two vertical rods 1 are respectively connected to the open slots 32 at both ends of the special connector 3.

[0038] Specifically, the open slots 32 at both ends enable the two vertical rods 1 to provide stable traction to the transverse alloy steel 2, and to transmit and balance the vibration kinetic energy during vibration.

[0039] like Figure 3 As shown, in the above embodiment, preferably, the flexible stress-relieving and seismic-resistant hanger also includes a connecting rod 5. The upper part of the connecting rod 5 is provided with a through connecting hole along the radial direction. The lower part of the special connector 3 is provided with an open groove 32. The upper end of the connecting rod 5 is inserted into the open groove 32 at the lower part of the special connector 3. At the same time, the transverse alloy steel 2 is inserted into the through connecting hole of the connecting rod 5. The lower end of the connecting rod 5 is fixed to the ceiling keel.

[0040] Specifically, the connecting rod 5 adopts the same connection method as the vertical hanger 1 to achieve the connection between the horizontal alloy steel 2 and the ceiling keel, while further reducing the transmission of vibration momentum and improving the seismic resistance.

[0041] like Figure 4 As shown, in the above embodiment, preferably, the special connector 3 has two parallel through-fixing holes 31. The opening direction of the open slot 32 is such that when the vertical rod 1 is inserted into the open slot 32, the through-connecting hole at the lower part of the vertical rod 1 corresponds to the through-fixing hole 31 at the upper part. A horizontal alloy steel 2 is inserted into the through-fixing hole 31 and the through-connecting hole of the vertical rod 1. When the connecting rod 5 is inserted into the open slot 32, the through-connecting hole of the connecting rod 5 corresponds to the through-fixing hole 31 at the lower part. Another horizontal alloy steel 2 is inserted into the through-fixing hole 31 and the through-connecting hole of the connecting rod 5.

[0042] Specifically, the vertical hanger 1 and the connecting rod 5 are respectively connected to two horizontal alloy steels 2. The two horizontal alloy steels 2 are respectively inserted into two parallel through fixing holes 31 in the special connector 3, so that the special connector 3 acts as a connection medium to isolate the vibration between the vertical hanger 1 and the connecting rod 5.

[0043] In the above embodiment, preferably, the horizontal alloy steel bars 2 are spaced 80cm apart. This spacing ensures the strength of the horizontal support without wasting materials. After multiple tests and practical applications, this spacing has been verified to effectively improve the overall stability of the ceiling.

[0044] In the above embodiments, preferably, the diameter of the vertical rod 1 is at least 15 mm to ensure its load requirements.

[0045] In the above embodiment, preferably, a damping pad is provided in the through fixing hole 31 and the open groove 32 to absorb vibration energy and reduce noise, so as to resist continuous low-frequency vibration and ensure the safety of the ceiling structure.

[0046] According to the flexible stress-relieving seismic suspension rod disclosed in the above embodiments, during implementation, the components are assembled using a detachable connection method. This design facilitates installation and operation, and also makes subsequent maintenance easier. The connection design between the vertical suspension rod 1, the special connector 3, and the horizontal alloy steel 2 allows the horizontal alloy steel 2 to rotate freely with the vertical suspension rod 1 under normal conditions; when vibration occurs, it can also quickly respond to vibrations in different directions.

[0047] Specifically, under normal conditions: the vertical hanger 1 is connected to the horizontal alloy steel 2 via a special connector 3. The horizontal alloy steel 2 can rotate and shift flexibly within a small range to adapt to the deformation of the ceiling caused by temperature changes or slight loads, thus maintaining structural stability. For example, when the temperature rises, the ceiling material will expand to a certain extent. The rotation of the horizontal alloy steel 2 can relieve the stress generated by this and prevent cracks or deformation of the ceiling.

[0048] When an earthquake or severe shaking occurs: Vertical hanger 1 utilizes the tensile properties of its high-strength alloy steel to absorb vibration energy and distribute the load through elastic deformation. Under strong vibration, the hanger will be stretched, converting the kinetic energy of the vibration into its own elastic potential energy, thereby reducing the energy transmitted to other parts of the ceiling.

[0049] Furthermore, with the help of special connector 3, the vertical hanger 1 and the horizontal alloy steel 2 can adjust their relative angle and position in real time according to the vibration direction, so that the force direction of the vertical hanger 1 always matches the vibration direction, avoiding local stress concentration. No matter which direction the vibration comes from, both can quickly adjust their relative state, allowing the vertical hanger 1 to resist the vibration in the best stress state.

[0050] Furthermore, the linkage mechanism between the vertical hanger 1, the special connector 3, and the horizontal alloy steel 2 creates a dynamic adaptive system for the entire ceiling structure, effectively buffering vibration impacts and protecting the integrity of the ceiling. These three components work together to ensure the safety of the ceiling during vibrations.

[0051] The following examples illustrate the structure, installation method, and testing results of flexible stress-relieving seismic suspension rods.

[0052] Example 1: Installation of standard ceiling seismic-resistant components

[0053] 1. Structural assembly:

[0054] The horizontal alloy steel 2 is fixed horizontally below the main ceiling keel, spaced 800mm apart.

[0055] The upper end of the vertical hanger 1 is welded to the embedded part of the building floor slab, and the lower end is inserted into the open slot 32 of the special connector 3. The horizontal alloy steel 2 is inserted into the through connection hole for fixation. Welding ensures the firmness of the connection between the vertical hanger 1 and the floor slab, and the through connection method ensures that the connection between the vertical hanger 1 and the special connector 3 is stable and easy to disassemble.

[0056] 2. Test Results: Tests were conducted on a simulated earthquake shaking table. When the vibration frequency reached 5Hz and the acceleration was 0.3g, the traditional ceiling structure experienced keel fracture. The component of this invention, through the tension of the hanger rods and the rotation of the connectors, dispersed the stress, allowing the entire ceiling to remain intact. Experimental data shows that the component of this invention can effectively improve the seismic performance of the ceiling.

[0057] Example 2: Application of suspended ceilings in large venues

[0058] To address the high ceilings and heavy loads required in large venues, the diameter of the vertical hanger 1 was increased to 16mm, and the horizontal alloy steel 2 was reinforced with an H-shaped cross-section. Special connector 3 was equipped with damping pads to absorb vibration energy and reduce noise. In practical applications, this component successfully withstood continuous low-frequency vibrations caused by the operation of the surrounding subway, ensuring the safety of the ceiling structure. In the unique environment of large venues, targeted improvements to the component met the requirements for earthquake resistance, noise reduction, and other aspects.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
