Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and more specifically, to a limiting device for seismic bracing hangers for multi-pipe systems. Background Technology

[0002] Seismic bracing is a key facility in building electromechanical engineering to resist earthquake disasters. Its core function is to reduce earthquake damage by restraining pipeline displacement.

[0003] When using control supports, the pipeline is limited by U-shaped limit rods and C-shaped steel. For ease of installation, multiple elongated holes are made in the C-shaped steel to allow the U-shaped limit rods to pass through. However, there is a gap between the elongated holes and the bolt connection. When the pipeline is seismically resisted, the pipeline is mainly limited by the friction between the bolts and the C-shaped steel. After long-term use, the friction between the bolts and the C-shaped steel gradually decreases, which can easily cause the pipeline to shake and affect the seismic resistance. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the gap between the elongated hole and the bolt connection affects the seismic performance, and to design a limiting device for seismic support and hangers for multi-pipe systems.

[0005] To achieve the above objectives, the technical solution of this utility model is a limiting device for a multi-pipe seismic support, comprising a holding platform, the holding platform being a C-shaped steel, the holding platform being connected to a fixed object via a connector, a plurality of U-shaped limiting rods being provided above the holding platform, the open ends of the U-shaped limiting rods facing downwards, the U-shaped limiting rods limiting the pipes, external threads being provided on both sides of the lower end of the U-shaped limiting rods, a plurality of first elongated holes being provided on the holding platform, the lower ends of the U-shaped limiting rods passing through the first elongated holes and extending below the holding platform, two limiting nuts being threadedly connected to the external threads, the two limiting nuts being located above and below the holding platform respectively, a plurality of limiting frames being installed on the holding platform, the limiting frames limiting the U-shaped limiting rods to prevent them from sliding left and right.

[0006] Furthermore, the limiting frame includes an L-shaped limiting plate located on one side of the serving platform. The L-shaped limiting plate has multiple first circular holes at both ends, and the serving platform has multiple second circular holes corresponding to the positions of the first circular holes. The L-shaped limiting plate is installed on the serving platform by bolts, and the upper sides of the L-shaped limiting plate are in contact with limiting nuts.

[0007] Furthermore, the L-shaped limiting plate has second elongated holes on both sides of its upper end.

[0008] Furthermore, the upper sides of the L-shaped limiting plate are provided with 45-degree bevels, and the side of the limiting nut on the upper end of the serving platform is in contact with the L-shaped limiting plate.

[0009] The beneficial effects of this utility model are as follows: By installing a limiting frame on the serving platform, the limiting frame can limit the U-shaped limiting rod. This adds another limiting force on top of the friction between the bolt and the serving platform. Even if there is a gap between the bolt and the elongated hole, the U-shaped limiting rod will not shake, thus ensuring the anti-vibration effect. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] This utility model provides, for example Figure 1-5 The illustrated limiting device for a multi-pipe seismic bracing system includes a holding platform 1, which is a C-shaped steel structure. The holding platform 1 is connected to a fixed object via a connector. Multiple U-shaped limiting rods 2 are provided above the holding platform 1, with the open ends of the U-shaped limiting rods 2 facing downwards. The U-shaped limiting rods 2 can limit the pipes 3. External threads are provided on both sides of the lower end of the U-shaped limiting rods 2. Multiple first elongated holes 4 are opened on the holding platform 1. The lower ends of the U-shaped limiting rods 2 pass through the first elongated holes 4 and extend below the holding platform 1. Two limiting nuts 5 are threadedly connected to the external threads. The two limiting nuts 5 are located above and below the holding platform 1, respectively. Multiple limiting frames 6 are installed on the holding platform 1. The limiting frames 6 can limit the U-shaped limiting rods 2 to prevent them from sliding left and right.

[0019] The process of this device for seismic resistance of pipelines is as follows: The holding platform 1 is installed on a fixed object through the connector. The U-shaped limiting rod 2 is upside down on the outside of the pipeline 3, and the lower end of the U-shaped limiting rod 2 is extended through the first elongated hole 4 to the bottom of the holding platform 1. The U-shaped limiting rod 2 is installed through the limiting nut 5. After installation, the limiting frame 6 is installed on the holding platform 1, and the limiting frame 6 can limit the U-shaped limiting rod 2, thereby preventing pipeline shaking and improving the seismic resistance effect.

[0020] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The limiting frame 6 includes an L-shaped limiting plate 7 located on one side of the serving platform 1. The L-shaped limiting plate 7 has multiple first round holes 8 at both ends. The serving platform 1 has multiple second round holes 9 corresponding to the positions of the first round holes 8. The L-shaped limiting plate 7 is installed on the serving platform 1 by bolt connection. The upper two sides of the L-shaped limiting plate 7 are in contact with the limiting nuts 5.

[0021] The process of limiting the U-shaped limiting rod 2 by the limiting frame 6 is as follows: After the U-shaped limiting rod 2 is installed, the L-shaped limiting plate 7 is placed on the serving platform 1, and the bolts are passed through the first round hole 8 and the second round hole 9 to connect the L-shaped limiting plate 7 to the serving platform 1, so that the L-shaped limiting plate 7 can be fixed. The L-shaped limiting plate 7 can fix the limiting nuts 5 on both sides. Since the limiting nuts 5 cannot move left and right, the U-shaped limiting rod 2 can be prevented from moving left and right.

[0022] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The upper end of the L-shaped limiting plate 7 has two second elongated holes 10 on both sides. One end of the bolt is passed through the second elongated hole 10 and the first elongated hole 4. The upper end of the L-shaped limiting plate 7 is installed on the holding platform 1 by bolt connection. This can prevent the L-shaped limiting plate 7 from rotating downward and also facilitate the L-shaped limiting plate 7 to move back and forth.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The upper end of the L-shaped limiting plate 7 has a 45-degree bevel on both sides. The side of the limiting nut 5 at the upper end of the holding platform 1 is in contact with the L-shaped limiting plate 7. Through the action of the bevel, the distance between the L-shaped limiting plate 7 and the limiting nut 5 can be easily adjusted when the L-shaped limiting plate 7 is moved back and forth, thereby reducing the machining accuracy of the L-shaped limiting plate 7 and increasing its practicality.
