Description

Technical Field

[0001] The utility model relates to the field of seismic structures, in particular to a seismic structure for pipelines to vertically pass through the bottom of a steel structure beam. Background Art

[0002] In the design and construction of modern buildings, the layout of pipeline facilities is crucial for the functions and safety of buildings. Especially in earthquake-prone areas, how to improve the seismic performance of pipeline systems without affecting the overall structure of buildings is a complex and important issue.

[0003] In traditional pipeline installation techniques, that is, pipelines are vertically laid along the bottom of a steel structure beam. Although it has advantages in terms of space utilization and construction convenience, its seismic performance is insufficient. Strong vibrations such as earthquakes can cause impacts and frictions between pipelines and the beam, resulting in pipeline damage and even potential safety hazards to the entire building structure.

[0004] To address this problem, the industry has taken some measures. For example, a Chinese utility model with the authorization publication number CN216976040U discloses a seismic support. In the published document, a short crossbar, a long crossbar, a vertical bar, and a diagonal bar are sequentially connected to form a seismic support. A support seat is provided on the long crossbar, and a pipe clamp is provided on the short crossbar to fix the steel structure beam and the pipeline. However, in the published document, the seismic support is only applicable to the case where pipelines pass parallel to the bottom of the steel structure beam. Moreover, the seismic support is connected end to end in a quadrilateral shape without a lateral fixing structure. During a strong earthquake, the instability of the quadrilateral seismic support easily leads to the detachment of the support, causing property losses and casualties.

[0005] Therefore, in the case where pipelines are perpendicular to the bottom of a steel structure beam, it is necessary to design a new type of seismic structure. This structure needs to ensure the stability of pipelines under normal conditions and provide sufficient seismic performance under dynamic loads such as earthquakes. Summary of the Utility Model

[0006] Aiming at the defects of the above-mentioned prior art, the utility model provides a seismic structure for pipelines to vertically pass through the bottom of a steel structure beam, aiming to improve the safety and stability of pipelines when they are perpendicular to the bottom of the steel structure beam and are subjected to dynamic loads such as earthquakes.

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows: an anti-seismic structure for a pipeline to vertically pass through the bottom of a steel structure beam. In this structure, the pipeline is located below the steel structure beam and is perpendicular to the direction of the steel structure beam. It is characterized in that the anti-seismic structure includes a pipeline fixing component fixed on the outer wall of the pipeline, a first top root component and a second top root component respectively connected to both ends of the pipeline fixing component. The upper ends of the first top root component and the second top root component are fixedly connected to the steel structure beam through beam clamps. The pipeline fixing component is further connected to a side root component obliquely arranged on one side of the pipeline, and the upper and lower ends of the side root component are respectively fixedly connected to the steel structure beam and the pipeline fixing component.

[0008] Due to the above components of the present utility model, this anti-seismic structure can offset the dynamic loads from the vertical direction and the pipeline direction through the first top root component and the second top root component, and the side root component can offset the dynamic load from the direction of the steel structure beam. In addition, the pipeline fixing component can provide a radial buffering effect for the pipeline. Therefore, compared with the known anti-seismic structures, this anti-seismic structure for a pipeline to vertically pass through the bottom of a steel structure beam can effectively improve the safety and stability of the pipeline under dynamic loads such as earthquakes.

[0009] In an embodiment of the present utility model, the pipeline fixing component includes a pipe clamp adapted to the pipeline and a cross-bar channel steel arranged below the pipe clamp. The pipe clamp is fixedly connected to the cross-bar channel steel through bolts and nuts, and a gasket is further arranged between the nut and the cross-bar channel steel. The pipeline passes through the pipe clamp, and a pipeline rubber pad is arranged on the inner wall of the pipe clamp.

[0010] The cross-bar channel steel is located below the pipeline, providing a stable and reliable radial support for the pipeline and enhancing the stability of the anti-seismic structure. Through the pipeline rubber pad, friction can be reduced and the pipeline can be prevented from being damaged, playing a buffering and protective role. The gasket can further ensure the reliability and stability of the bolt connection. The structural design of the pipeline fixing component is relatively simple, easy to install and disassemble, and also convenient for the maintenance and replacement of the pipeline. In summary, the pipeline fixing component of the present utility model can not only effectively fix the pipeline, but also has good anti-seismic performance and a protective effect on the pipeline, and its structural design is simple and practical.

[0011] In an embodiment of the present utility model, both the first top root component and the second top root component include a top cross-channel steel fixedly connected to the steel structure beam through the beam clamp, a screw rod fixedly connected between the top cross-channel steel and the pipeline fixing component through the nut and the gasket. A top inclined channel steel is obliquely arranged between the top cross-channel steel and the screw rod and is connected through a hinge component. A top longitudinal channel steel is sleeved outside the screw rod, and the top longitudinal channel steel is attached to the screw rod through a plurality of stiffening devices.

[0012] Due to the characteristics of the steel structure beam itself, it is inconvenient to adopt a rooting structure such as inserting anchor bolts on it. The utility model uses the beam clamp to fix the top horizontal channel steel and the steel structure beam, effectively solving the problem of difficult rooting on the steel structure beam; in addition, both the first top rooting component and the second top rooting component are triangular and connected end to end, having good stability. Considering that a longer installation span is likely to cause the stiffness of the screw rod to decrease, resulting in the failure of the first top rooting component or the second top rooting component, a top longitudinal channel steel is sleeved outside the screw rod, and the screw rod is resisted by the stiffening device, restricting the range of deformation and swing of the screw rod under strong dynamic loads, improving the stiffness of the screw rod, and further ensuring the stability of the first top rooting component and the second top rooting component; the screw rod connects the top horizontal channel steel and the pipeline fixing component through the bolt, which can effectively resist the dynamic load from the axial direction of the screw rod, thereby improving the safety of the seismic device.

[0013] In an embodiment of the utility model, the stiffening device includes a special-shaped bolt, a special-shaped nut adapted to the special-shaped bolt, and a V-shaped claw adapted to the screw rod. The special-shaped nut can freely slide inside the open surface of the top longitudinal channel steel and is provided with a threaded hole in the middle. The bottom end of the special-shaped bolt is provided with a convex platform, and a circle of convex edges is provided at the outermost end of the convex platform. The V-shaped claw is movably connected to the convex platform through a connection hole opened at the bottom, and the V-shaped claw is restricted inside the convex edges.

[0014] The special-shaped nut can freely slide inside the open surface of the top longitudinal channel steel, so that the position of the stiffening device can be adjusted after installation, thus adapting to different installation environments and requirements; through the cooperation of the special-shaped nut and the special-shaped bolt, when the special-shaped bolt is tightened, the special-shaped nut rises along the thread until it abuts against the inner side of the open surface of the top longitudinal channel steel, thereby fixing the relative position of the top longitudinal channel steel and the screw rod; and the movable connection between the convex platform and the connection hole can ensure that when the V-shaped claw positions the screw rod, the special-shaped bolt can still rotate freely, and the convex edges can ensure that the V-shaped claw will not break out of the convex platform without external force; in addition, when the V-shaped claw abuts against the screw rod, the screw rod receives support forces from three different directions, effectively improving the safety and stability of the screw rod against strong vibration loads from different directions.

[0015] In an embodiment of the utility model, the side rooting component includes a side horizontal channel steel fixedly connected to the steel structure beam through the beam clamp, and a side inclined channel steel obliquely arranged between the side horizontal channel steel and the screw rod and connected through a hinge component.

[0016] Based on the top root component, the present utility model further incorporates the side root component, aiming to better resist the dynamic load from the direction of the steel structure beam. The hinge component can provide a certain buffering effect for the seismic structure, effectively improving the stability and safety of the seismic structure.

[0017] In an embodiment of the present utility model, the beam clamp includes a U-shaped frame adapted to the top horizontal channel steel or the side horizontal channel steel, and a clamping arm penetrated by the open end of the U-shaped frame. A beam clamp bolt is further provided at the part where the U-shaped frame penetrates through the clamping arm.

[0018] Through the cooperation of the U-shaped frame and the clamping arm, the beam clamp can be firmly fixed on the top horizontal channel steel or the side horizontal channel steel, ensuring the stability of the entire seismic structure. The beam clamp bolt passes through the U-shaped frame and the clamping arm, making the connection between the beam clamp and the channel steel closer, improving the rigidity and seismic performance of the seismic structure. Due to the presence of the beam clamp bolt, the installation and disassembly of the beam clamp become relatively simple, which is beneficial for maintenance and adjustment. The beam clamp has a compact design structure, does not occupy too much space, and at the same time ensures sufficient mechanical strength and durability. In summary, the beam clamp design of the present utility model has strong practicability, stability and seismic resistance, and is of great significance for ensuring the safety and reliability of the entire pipeline seismic structure.

[0019] In an embodiment of the present utility model, the hinge component includes a first hinge member adapted to the top horizontal channel steel or the side horizontal channel steel and a second hinge member adapted to the bolt, and the first hinge member and the second hinge member are cooperated by means of hinging.

[0020] By the first hinge member adapting to the top horizontal channel steel or the side horizontal channel steel and the second hinge member adapting to the bolt, the hinge component can rotate flexibly, facilitating adjustment and alignment during installation. Even when subjected to a force at a certain angle, the hinge component can absorb and disperse the force through rotation, maintaining the stability of the structure. Due to the rotational characteristics of the hinge component, it can resist vibrations from different directions, increasing the flexibility and toughness of the seismic structure. In addition, if maintenance or replacement of the pipeline or other components is required, the rotational characteristics of the hinge component can make the operation simpler and more convenient.
