A seismic support for integrated utility tunnels

Abstract

This utility model discloses a seismic-resistant support for integrated utility tunnels, including a supporting beam and a utility tunnel body. A supporting auxiliary mechanism is provided at the lower end of the supporting beam. The supporting auxiliary mechanism includes a fixing frame placed at the lower end of the supporting beam, and a connecting ring is fixedly connected to the lower end of the fixing frame. The lower end of the connecting ring is fixedly connected with a thread. This utility model discloses a seismic-resistant support for integrated utility tunnels. By placing the utility tunnel body inside the supporting ring, and then folding the supporting ring to fit the diameter of the utility tunnel body, the limiting ring causes the contact pad to fit against the outer side of the utility tunnel body. Subsequently, by twisting the internal threaded ring in the opposite direction, the internal threaded ring moves downwards to the contact control frame, thus facilitating the confinement of the utility tunnel body below the supporting beam and controlling the downward movement distance of the limiting ring. This allows for the confinement of utility tunnel bodies of different diameters, enabling the installation of utility tunnel bodies of different diameters below the supporting beam.

Description

Technical Field

[0001] This utility model relates to the field of seismic support technology for utility tunnels, and in particular to a comprehensive seismic support for utility tunnels. Background Technology

[0002] A pipe gallery is a corridor for pipelines. In chemical and related plants, many pipelines are concentrated together and laid out along the outside of the equipment or plant, usually in the air and supported by brackets, forming a corridor-like structure. A few pipe galleries are located underground.

[0003] Traditional seismic bracing for utility tunnels has some drawbacks. During the construction of integrated utility tunnels, the existing support structure design has obvious adaptability defects, making it difficult for construction workers to install pipelines of different diameters. This structural limitation not only reduces construction efficiency but also increases the difficulty of installing irregularly shaped pipes, ultimately affecting the overall compatibility and scalability of the utility tunnel system. Utility Model Content

[0004] The main purpose of this utility model is to provide a seismic-resistant support for integrated utility tunnels, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An integrated utility tunnel seismic support includes a supporting beam and a main body of the utility tunnel. A supporting auxiliary mechanism is provided at the lower end of the supporting beam. The supporting auxiliary mechanism includes a fixed frame placed at the lower end of the supporting beam.

A supporting ring is fixedly connected to the lower end of the threaded rod. A control frame is slidably connected to the outer side of the threaded rod. A limiting ring is fixedly connected to the upper end of the control frame. A contact pad is fixedly connected to the inner wall of the limiting ring. An internal threaded ring is threadedly connected to the outer side of the threaded rod near the upper side of the control frame.

[0007] Preferably, the front end of the fixing frame is fixedly connected to a support frame, the inner side of the support frame is threaded with a limiting bolt, the mating ring is arc-shaped, and the support ring is arc-shaped.

[0008] Preferably, the center points of the limiting ring and the contact pad are located at the same point, the lower end of the internal threaded ring contacts the upper end of the control frame near the front side of the limiting ring, the limiting bolt extends into the interior of the support beam, and the limiting bolt is threadedly connected to the support beam.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By placing the main body of the pipe rack inside the support ring and then folding the support ring to fit the diameter of the main body of the pipe rack, the limiting ring moves the contact pad to fit the outer side of the main body of the pipe rack. Then, by twisting the internal threaded ring in the opposite direction, the internal threaded ring moves downward to the contact control frame. This achieves the purpose of limiting the main body of the pipe rack below the support beam and controlling the downward movement distance of the limiting ring. This allows for the limitation of pipe rack main bodies of different diameters, thus enabling the installation of pipe rack main bodies of different diameters below the support beam.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a seismic-resistant support for a utility tunnel includes a supporting beam 1 and a main body 2. A supporting auxiliary mechanism 4 is provided at the lower end of the supporting beam 1. The supporting auxiliary mechanism 4 includes a fixed frame 41 placed at the lower end of the supporting beam 1. A docking ring 42 is fixedly connected to the lower end of the fixed frame 41. A threaded rod 43 is fixedly connected to the lower end of the docking ring 42. A supporting ring 44 is fixedly connected to the lower end of the threaded rod 43. A control frame 45 is slidably connected to the outer side of the threaded rod 43. A limiting ring 46 is fixedly connected to the upper end of the control frame 45. A contact pad 47 is fixedly connected to the inner wall of the limiting ring 46. An internal threaded ring 48 is threadedly connected to the outer side of the threaded rod 43 near the upper side of the control frame 45.

[0021] In this embodiment, a support frame 49 is fixedly connected to the front end of the fixed frame 41. A limiting bolt 410 is threadedly connected to the inner side of the support frame 49. The mating ring 42 is arc-shaped, and the support ring 44 is arc-shaped. The axis points of the limiting ring 46 and the contact pad 47 are located at the same point. The lower end of the internal threaded ring 48 contacts the upper end of the control frame 45 near the front side of the limiting ring 46. The limiting bolt 410 extends into the interior of the support beam 1 and is threadedly connected to the support beam 1. There are two sets of threaded rods 43, control frame 45, and internal threaded rings 48. The main material of the contact pad 47 is rubber, and the main materials of the mating ring 42 and the support ring 44 are deformable metals.

[0022] Specifically, rotating the internal threaded ring 48 causes it to move upward along the threaded rod 43, then pulling the limiting ring 46 upward, and causing the limiting ring 46 to drive the control frame 45 upward along the threaded rod 43, placing the pipe rack body 2 inside the support ring 44, then folding the support ring 44 to fit the diameter of the pipe rack body 2, and then pulling the limiting ring 46 downward, causing the limiting ring 46 to drive the contact pad 47 to fit the outer side of the pipe rack body 2, and then twisting the internal threaded ring 48 in the opposite direction, causing the internal threaded ring 48 to move downward to contact the control frame 45, thus limiting the pipe rack body 2. Below the supporting beam 1, by placing the pipe rack body 2 inside the supporting ring 44 and then folding the supporting ring 44 to fit the diameter of the pipe rack body 2, the limiting ring 46 drives the contact pad 47 to fit the outer side of the pipe rack body 2. Then, by twisting the internal thread ring 48 in the opposite direction, the internal thread ring 48 moves downward to the contact control frame 45, which can facilitate the limitation of the pipe rack body 2 below the supporting beam 1 and control the downward movement distance of the limiting ring 46. This can limit pipe rack bodies 2 of different diameters, so that pipe rack bodies 2 of different diameters can be installed below the supporting beam 1.

[0023] In this embodiment, the main body 2 of the pipe gallery is installed inside the support ring 44. The inner side of the contact pad 47 is in contact with the outer side of the main body 2 of the pipe gallery near the upper side of the support ring 44. The axis lines of the main body 2 of the pipe gallery, the limiting ring 46, the contact pad 47, and the support ring 44 are located on the same straight line. One end of the main body 2 of the pipe gallery is fixedly connected to the docking side plate 3. The shape of the support beam 1 is I-shaped.

[0024] Specifically, the preparation work for installing the main body 2 of the pipe gallery is completed by fixing the support beam 1 to the top of the designated building, placing the fixing bracket 41 under the support beam 1, and then screwing the limiting bolt 410 into the inside of the support bracket 49 and the limiting bolt 410 into the inside of the support beam 1.

[0025] Working principle:

[0026] During installation, first, the supporting beam 1 is fixed to the top of the designated building, and the fixing bracket 41 is placed below the supporting beam 1. Then, the limiting bolt 410 is screwed into the inside of the supporting bracket 49 and into the inside of the supporting beam 1. Then, the internal threaded ring 48 is rotated, causing it to move upward along the threaded rod 43. Then, the limiting ring 46 is pulled upward, causing the limiting ring 46 to drive the control bracket 45 to move upward along the threaded rod 43. The pipe rack body 2 is then placed inside the supporting ring 44. The supporting ring 44 is then folded to fit the diameter of the pipe rack body 2, and the limiting ring 46 is pulled downward, causing the limiting ring 46 to drive the contact pad 47 to fit against the outside of the pipe rack body 2. Then, by reversing the internal threaded ring 48, the internal threaded ring 48 moves downward to the contact control frame 45, thus confining the pipe rack body 2 below the support beam 1. By placing the pipe rack body 2 inside the support ring 44 and then folding the support ring 44 to fit the diameter of the pipe rack body 2, the limiting ring 46 drives the contact pad 47 to fit the outside of the pipe rack body 2. Subsequently, by reversing the internal threaded ring 48, the internal threaded ring 48 moves downward to the contact control frame 45, which can facilitate confining the pipe rack body 2 below the support beam 1 and control the downward movement distance of the limiting ring 46. This allows for the confinement of pipe rack bodies 2 of different diameters, thus enabling the installation of pipe rack bodies 2 of different diameters below the support beam 1.
