Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rail transit construction technology, and specifically relates to an adjustable integrated bracket for the suspension installation of pipelines in subway stations. Background Technology
[0002] Subway station piping involves multiple disciplines, including electrical, communication, platform screen doors, signaling, ventilation, air conditioning, water supply and drainage, refrigerant pipes, and fire protection pipes. The drawing schedules for each discipline are inconsistent, requiring installation to proceed concurrently with drawing completion to expedite construction. Therefore, the installation height and support space for the pipes are uncertain at the start of installation. Currently, most pipe suspension supports are welded steel frames, which are non-adjustable, have poor adaptability, and cannot accommodate additional pipes after installation. Adding pipes becomes extremely complicated when necessary. Utility Model Content
[0003] This utility model provides an adjustable integrated bracket for the suspension installation of pipelines in subway stations to solve the technical problems existing in the prior art. The bracket is height-adjustable, highly adaptable, and easy to install.
[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: an adjustable integrated bracket for the suspension installation of pipelines in subway stations, including two hanging arms, the hanging arms being made of perforated C-shaped steel and fixed at the upper end to the ceiling of the subway station. Multiple cross braces are provided between the two hanging arms, and each end of the cross brace is connected to the hanging arm through a clamping connector. The clamping connector is connected to the cross brace and the hanging arm respectively through bolt I.
[0005] Based on the above solution, the present invention has made the following improvements:
[0006] An anti-seismic bracket is installed on the hanging arm located at the seismic resistance position. The anti-seismic bracket is composed of diagonal braces, which are set on the side of the hanging arm and connected to the ceiling of the subway station at the upper end. The diagonal braces are made of perforated C-shaped steel.
[0007] The upper end of the hanging arm is fixed to the ceiling of the subway station via a connecting support. The connecting support is provided with an outer sleeve adapted to the hanging arm. The outer sleeve is made of perforated C-shaped steel and is connected to the hanging arm by bolts II. A connecting steel plate I is provided on the top of the outer sleeve, and the connecting steel plate I is connected to the ceiling of the subway station by bolts III.
[0008] The upper end of the diagonal brace is connected to the ceiling of the subway station by bolt IV through connecting steel plate II, and the connecting steel plate II is connected to the upper end of the diagonal brace by hinge.
[0009] The advantages and positive effects of this utility model are as follows: The hanging arm, made of perforated C-shaped steel, can be lengthened through core sleeves and bolt connections, thereby increasing the installation space of the support and allowing it to accommodate more pipes. Simultaneously, because the cross braces are connected to the hanging arm via compression fittings and bolts, the position of the cross braces is adjustable. By adjusting the spacing between adjacent cross braces, it can flexibly adapt to changes in pipe diameter, accommodating design changes and subsequent modifications. Furthermore, this utility model incorporates an anti-seismic structure on the hanging arm located in seismic-resistant positions. During earthquakes, this structure can bear longitudinal and lateral forces, dissipating seismic energy and reducing the degree of damage to the support. Moreover, this utility model has a simple structure and is easy to install and construct. Attached Figure Description

[0012] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0013] Please see Figure 1 An adjustable integrated bracket for suspending pipelines in a subway station includes two hanging arms 1, which are made of perforated C-shaped steel and are fixed to the ceiling of the subway station at the upper end. Multiple cross braces 3 are provided between the two hanging arms 1. Each end of the cross brace 3 is connected to the hanging arm 1 through a clamping connector 3-1. The clamping connector 3-1 is connected to the cross brace 3 and the hanging arm 1 respectively through bolts I.
[0014] The hanging arm is made of perforated C-shaped steel, which is easy to extend and thus increase the installation space, allowing for the installation of more pipelines. The cross brace is connected to the hanging arm with a compression fitting, and its position is adjustable, facilitating pipeline layout. The components are connected by bolts, making construction simple.
[0015] The more preferred solution in this embodiment is as follows:
[0016] An anti-seismic support is installed on the hanging arm 1 located at a seismic-resistant position. The anti-seismic support consists of diagonal braces 5, which are located on the side of the hanging arm 1 and connected to the ceiling of the subway station at their upper ends. The diagonal braces 5 are made of perforated C-shaped steel. The diagonal braces 5 can absorb seismic energy and reduce the damage to the integrated support structure when an earthquake occurs.
[0017] The upper end of the hanging arm 1 is fixed to the ceiling of the subway station via a connecting support. The connecting support is equipped with an outer sleeve 2-2 adapted to the hanging arm 1. The outer sleeve 2-2 is made of perforated C-shaped steel and is connected to the hanging arm 1 by bolts II. A connecting steel plate I2-1 is provided on the top of the outer sleeve 2-2, and the connecting steel plate I2-1 is connected to the ceiling of the subway station by bolts III. This structure is easy to install.
[0018] The upper end of the diagonal brace 5 is connected to the ceiling of the subway station by bolt IV through connecting steel plate II4. The connecting steel plate II4 is connected to the upper end of the diagonal brace 5 by hinge, which makes installation simple.
[0019] During construction, first connect the cross brace 3 to the two hanging arms 1, adjust the cross brace 3 to a suitable position, and align the screw holes of the ferrule connector 3-1 with the screw holes on the two hanging arms 1 respectively. Insert the bolt I into the screw hole and tighten it to fix the cross brace 3 between the two hanging arms 1. In the same way, fix the other cross braces 3 to a suitable position between the two hanging arms 1.
[0020] Install the connecting seat on the top of the hanging arm 1, and then fix the connecting steel plate I2-1 on the connecting seat to the ceiling of the subway station, so that the bracket is suspended on the ceiling of the subway station according to the pipeline route. Install the diagonal brace 5, and set the connecting steel plate II4 hinged to the top of the diagonal brace 5, so that it forms a certain angle with the corresponding hanging arm. Then, use bolts to connect its lower end to the hanging arm 1, and use bolt IV to fix its top connecting plate II4 to the ceiling of the subway station. When the subway station shakes due to an earthquake, the diagonal braces 5 on both sides pull the hanging arm to both sides, which can resist the earthquake force.
[0021] For an already installed adjustable integrated support structure, when it is necessary to add electromechanical pipelines, the installation position of the new pipelines can be formed by extending the hanging arm and adding cross braces, or by adjusting the spacing of the cross braces and then adding cross braces.
[0022] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
