Description

Technical Field

[0001] This invention belongs to the field of ancient architecture technology, specifically relating to an imitation ancient building roof ridge structure. Background Technology

[0002] Currently, the roof ridge structures of imitation ancient buildings mostly refer to the construction methods of traditional wooden buildings. Commonly, they consist of a combination of components such as the ridge body, ridge ornaments, roof tiles, and side eaves. These structures typically use reinforced concrete or modern metal materials to imitate the form of wooden components, forming an integral ridge through prefabrication or cast-in-place methods. Since the ridge is usually located at the top of the building, the traditional rigid connection method makes the ridge almost fixed to the main structure, lacking sufficient energy dissipation and deformation coordination capabilities. When an earthquake occurs, the horizontal reciprocating force is transmitted through the ridge to its ends and weak points in the middle, easily leading to damage to the building's ridge. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an antique-style roof ridge structure that can protect the main structure of the roof ridge from damage during an earthquake, improve the building's earthquake resistance, and reduce building losses.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses an antique-style building ridge structure, comprising several ridge tubes evenly spaced along the transverse direction, with adjacent ridge tubes connected by brittle tubes. A rotating shaft is coaxially mounted in the middle of each ridge tube, and a rotation damping element is provided between the rotating shaft and the inner wall of the ridge tube. A notch is provided on the lower side of the middle of the rotating shaft, and a roof truss is hinged within the notch. Each group of ridge tubes is equipped with a corresponding group of roof trusses, and multiple groups of roof trusses are evenly spaced along the transverse direction. Support beams are provided between the multiple groups of roof trusses along the transverse direction. Two sets of spring dampers are installed between the ridge tubes and the support beams, and the two sets of spring dampers are symmetrically arranged on both sides of the roof truss. An axial damping element is also connected between adjacent ridge tubes, and the brittle tube is located outside the axial damping element.

[0005] Furthermore, the rotational damping component includes a damping bladder fixed inside the ridge tube, the damping bladder extending axially along the ridge tube and filled with damping fluid, and multiple protrusions arranged circumferentially on the outer side of the rotation shaft, the protrusions being fixed axially on the outer side of the rotation shaft, and the rotation shaft being able to compress the damping bladder when the rotation shaft rotates relative to the ridge tube.

[0006] Furthermore, the two ends of the damping bladder are connected to the compression bladder through branch pipes. The compression bladder is fixed to the inside of a vertical cylinder. A pressure block is threaded inside the vertical cylinder. The pressure block is connected to the handle through a support rod. Holes are opened on the ridge cylinder for the support rod to pass through.

[0007] Furthermore, a first limiting plate and a second limiting plate are arranged horizontally at intervals inside the ridge tube, and the interval between the first limiting plate and the second limiting plate forms a rotation space for the rotating shaft to rotate.

[0008] Furthermore, axial damping components are provided at both ends of the ridge tube. The axial damping components include a first baffle and a second baffle, which are spaced apart inside the ridge tube. A damping cavity is formed between the first baffle and the second baffle, and the damping cavity is filled with damping fluid. A movable plate is slidably arranged inside the damping cavity, and a damping hole is opened on the movable plate. A connecting rod is fixedly connected to the movable plate. A ball head is fixedly connected to the connecting rod of one set of axial damping components, and a ball seat is fixedly connected to the connecting rod of the other set of axial damping components. The ball head and the ball seat cooperate with each other.

[0009] Furthermore, the roof truss includes two upper chords and one lower chord arranged in a triangle. The tops of the two upper chords form the apex of the triangle, through which the roof truss is hinged to the rotation axis. The middle parts of the two upper chords are connected by a middle lower chord parallel to the lower chord. Vertical members are connected between the upper end of the upper chord and the middle lower chord, and between the middle lower chord and the lower chord. The upper chord and the lower chord are connected by multiple diagonal web members.

[0010] Furthermore, the support beam includes two parallel horizontal beams and a limiting beam connecting the two horizontal beams. The two limiting beams form a set, and a set of limiting beams is set on both sides of the roof truss. An opening is formed between the set of limiting beams for the vertical members of the roof truss to pass through.

[0011] The beneficial effects of this invention are as follows: This invention discloses an antique-style building ridge structure, which is composed of multiple ridge tubes. When an earthquake occurs, the brittle tubes are damaged. The main ridge tubes can dissipate energy through axial damping components, while the ridge tubes and roof trusses can dissipate energy through spring dampers. This achieves the purpose of energy dissipation and shock reduction, thereby protecting the main structure of the ridge from damage, improving the building's earthquake resistance, and reducing building losses.

[0014] like Figures 1-5 As shown, this invention discloses an antique-style building ridge structure, comprising a plurality of ridge tubes 1 evenly spaced laterally. Each ridge tube 1 is a cylindrical structure made of stainless steel. Adjacent ridge tubes 1 are connected by a brittle tube 2, which can be made of wood or cast-in-place concrete. Compared to the ridge tubes 1, the brittle tube 2 is more easily damaged. This allows for the active absorption of energy and the interruption of the continuous transmission path of vibration waves, avoiding the chain reaction of damage caused by rigid connections. The cost of replacing the brittle tube 2 is far lower than repairing the entire ridge, significantly reducing maintenance costs throughout its lifecycle.

[0015] Specifically, a rotating shaft 3 is coaxially mounted in the middle of the ridge tube 1 of this invention. The rotating shaft 3 can rotate around the axis of the ridge tube 1, and a rotation damping element is provided between the rotating shaft 3 and the inner wall of the ridge tube 1. A notch 4 is opened on the lower side of the middle of the rotating shaft 3, and a roof truss 5 is hinged in the notch 4. The plane of the roof truss 5 is perpendicular to the axis of the ridge tube 1. Each set of ridge tubes 1 is equipped with a set of roof trusses 5. Multiple sets of roof trusses 5 are evenly spaced in the transverse direction. Support beams 6 are provided in the transverse direction between multiple sets of roof trusses 5. Two sets of spring dampers 7 are installed between the ridge tube 1 and the support beams 6. The two sets of spring dampers 7 are symmetrically arranged on both sides of the roof trusses 5. An axial damping element is also connected between two adjacent ridge tubes 1, and a brittle cylinder 2 is located on the outside of the axial damping element. When the roof truss 5 is subjected to lateral forces such as wind loads or earthquakes, the roof truss 5 will cause the rotating shaft 3 to rotate relative to the ridge tube 1. At this time, the rotational damping element located between the rotating shaft 3 and the inner wall of the ridge tube 1 will generate damping force due to relative motion, converting mechanical energy into heat energy for dissipation, thereby significantly reducing the vibration amplitude transmitted from the roof truss 5 to the ridge. Simultaneously, two sets of symmetrically arranged spring dampers 7 installed between the ridge tube 1 and the support beam 6 can provide bidirectional elastic restoring force and additional damping when relative displacement occurs between the roof truss 5 and the ridge tube 1: the spring portion ensures that the roof truss 5 can accurately reset after vibration, avoiding permanent deformation; the damper portion further absorbs vibration energy, suppressing repeated oscillations of the roof truss 5.

[0016] In this embodiment, the rotational damping component includes a damping bladder 8 fixed inside the ridge cylinder 1. The damping bladder 8 extends axially along the ridge cylinder 1 and is filled with damping fluid. Multiple protrusions 9 are circumferentially arranged on the outer side of the rotating shaft 3, and these protrusions 9 are fixed to the outer side of the rotating shaft 3 along its axial direction. When the rotating shaft 3 rotates relative to the ridge cylinder 1, it compresses the damping bladder 8. When the rotating shaft 3 rotates due to external force, the protrusions 9 on its outer wall sequentially squeeze the damping bladder 8, forcing the damping fluid inside the bladder 8 to flow through a narrow channel, thereby generating a damping torque based on viscous energy dissipation. The damping force is non-linearly related to the rotational speed, achieving ideal energy dissipation characteristics of low resistance at low speeds and high resistance at high speeds. This ensures that minor adjustments during normal use are not affected, while providing strong damping rapidly during sudden and severe vibrations.

[0017] In this embodiment, the two ends of the damping bladder 8 are connected to the compression bladder 11 via branch pipes 10. The compression bladder 11 is fixed to the inside of a vertical cylinder 12. A pressure block 13 is threaded into the vertical cylinder 12. The pressure block 13 is connected to the handle 15 via a support rod 14. A hole is provided on the ridge cylinder 1 for the support rod 14 to pass through. The design of connecting the two ends of the damping bladder 8 to the compression bladder 11 via branch pipes 10, and adjusting the internal volume of the compression bladder 11 via the handle 15, support rod 14, and pressure block 13, provides the present invention with the function of on-site adjustment of damping characteristics.

[0018] In this embodiment, a first limiting plate 16 and a second limiting plate 17 are arranged laterally inside the ridge tube 1, forming a rotational space between the first limiting plate 16 and the second limiting plate 17 for the rotating shaft 3 to rotate. This prevents the rotating shaft 3 from axially shifting under long-term vibration or temperature deformation, thereby ensuring that the protrusion 9 on the rotating shaft 3 always maintains the axial alignment relationship required by the design with the damping bladder 8.

[0019] In this embodiment, axial damping components are provided at both ends of the ridge tube 1. The axial damping components include a first baffle 18 and a second baffle 19, which are spaced apart inside the ridge tube 1, forming a damping cavity between them. The damping cavity is filled with damping fluid, and a movable plate 20 is slidably disposed inside the damping cavity. The movable plate 20 has a damping hole 21 and is fixedly connected to a connecting rod 22. One set of connecting rods 22 of the axial damping components is fixedly connected to a ball head 23, and the other set of connecting rods 22 of the axial damping components is fixedly connected to a ball seat 24. The ball head 23 and the ball seat 24 cooperate with each other. When the seismic wave generates a lateral vibration component, the connecting rod 22 in the axial damping components between adjacent ridge tubes 1 will push the movable plate 20 to slide in the damping cavity, forcing the damping fluid to generate a throttling effect through the damping hole 21 on the movable plate 20, thereby dissipating the axial vibration energy.

[0020] In this embodiment, the roof truss 5 includes two upper chords 25 arranged in a triangle and a bottom lower chord 26. The tops of the two upper chords 25 form the apex of the triangle, through which the roof truss 5 is hinged to the rotation shaft 3. The middle parts of the two upper chords 25 are connected by a middle lower chord 27 parallel to the bottom lower chord 26. Vertical members 28 are connected between the upper end of the upper chord 25 and the middle lower chord 27, and between the middle lower chord 27 and the bottom lower chord 26. The upper chords 25 and the bottom lower chord 26 are connected by multiple diagonal web members 29. The grid arrangement of the vertical members 28 and the diagonal web members 29 divides the relatively slender upper chords 25 into multiple short segments, effectively preventing the upper chords 25 from buckling under pressure.

[0021] In this embodiment, the support beam 6 includes two parallel crossbeams 30 and a limiting beam 31 connecting the two crossbeams 30 together. The two limiting beams 31 form a group, and a group of limiting beams 31 are correspondingly arranged on both sides of the roof truss 5. An opening is formed between the group of limiting beams 31 for the vertical rod 28 of the roof truss 5 to pass through. The two parallel crossbeams 30 connect multiple groups of roof trusses 5 into a whole in the transverse direction, ensuring that all roof trusses 5 can work together under horizontal loads, avoiding individual roof trusses 5 from being displaced and torsional. At the same time, the crossbeams 30 themselves, as longitudinal members, can bear and transmit the horizontal force reacted on the ridge tube 1 by the spring damper 7, effectively protecting the ridge tube 1 from damage.
