All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a finished integrated crossbar device, comprising:

[0026] Concrete floor slab 1;

[0027] Two fixed anchors 2 are provided, and each fixed anchor 2 is installed at the bottom of the outer wall of the concrete floor slab 1;

[0028] There are two hangers 3, and each hanger 3 is connected to the concrete floor slab 1 by a fixed anchor bolt 2;

[0029] The load-bearing mechanism is located between each of the hangers 3. The load-bearing mechanism includes a main crossbeam 4 and two secondary crossbeams 5. The main crossbeam 4 is installed between each of the hangers 3, and each secondary crossbeam 5 is installed between each of the hangers 3.

[0030] The installation mechanism is located on the hanger 3.

[0031] In this implementation plan: Anchor bolts 2 are used to fix the hanger rods 3 onto the concrete floor slab 1. The anchor bolts 2 are hot-dip galvanized metal anchor bolts. Through the load-bearing mechanism, they can meet the requirements of the ceiling load and pipeline support, facilitating the installation of various equipment and pipelines. The main crossarm 4 is used to bear the load of the pipelines and ceiling, and reserves installation conditions for related professional terminal equipment. The cross-sectional dimensions of the main crossarm 4 are not less than 200mm × 110mm × 6mm. The main crossarm 4 has reserved installation holes for equipment such as fluorescent lights, broadcasting systems, cameras, and directional signs, and the installation position can be adjusted arbitrarily. The secondary crossarm 5 is used to install and fix various pipeline trenches. The edge of the secondary crossarm 5 has toothed grooves with a tooth depth ≥ 1mm. The toothed grooves ensure the reliability of equipment and pipeline fixing and allow for flexible ceiling expansion. The mechanical properties of the main crossarm 4 and the secondary crossarm 5 meet the load requirements of the subway station hall or other public areas of the platform. Through the installation mechanism, the main crossarm 4 and the two secondary crossarms 5 are installed and fixed on the hanger rod 3, increasing the stability of the connection.

[0032] Specifically, the installation mechanism includes two steel bases 6, multiple L-shaped connectors 7, and multiple fixed steel spring nuts 8. Each steel base 6 is bolted to the inner wall of the main crossarm 4. Each hanger 3 is connected to the steel base 6 via L-shaped connectors 7 and bolts. Each secondary crossarm 5 is connected to each hanger 3 via L-shaped connectors 7 and fixed steel spring nuts 8.

[0033] In this embodiment: the steel base 6 facilitates the installation of the main crossarm 4 between each hanger 3 and ensures that the main crossarm 4 is flat and free from deformation.

[0035] In this embodiment, the electromechanical pipeline is installed on the secondary crossarm 5 by means of insulated shockproof pipe clamps 9, which can adapt to the vibration and impact of the electromechanical pipeline and ensure safe operation.

[0036] Specifically, the outer walls of the main crossarm 4 and each secondary crossarm 5 are fixedly provided with a first galvanized layer 10.

[0037] In this embodiment: the main crossarm 4 and each secondary crossarm 5 are hot-dip galvanized. The main crossarm 4 is a cold-bent hot-dip galvanized U-shaped channel steel, and the secondary crossarm 5 is a cold-pressed hot-dip galvanized channel steel.

[0038] Specifically, the thickness of each first zinc plating layer 10 is ≥75μm.

[0039] In this embodiment, the corrosion resistance of the main crossarm 4 and each secondary crossarm 5 is increased by the first galvanized layer 10, making the device suitable for humid, high-humidity environments and environments with stray current corrosion.

[0040] Specifically, a second galvanized layer 11 is fixedly provided on the outer wall of each steel base 6, multiple L-shaped connectors 7 and multiple fixed steel spring nuts 8, and the thickness of each second galvanized layer 11 is ≥40μm.

[0041] In this embodiment, the steel base 6, the L-shaped connector 7, and the shaped steel spring nut 8 are all hot-dip galvanized parts, which can ensure the long-term stability of the device in high humidity and corrosive environments.

[0042] In use, the main crossarm 4 and two secondary crossarms 5 are installed on the hanger 3 through the steel base 6, L-shaped connector 7, and fixed steel spring nut 8, ensuring the stability of the connection. The setting of the main crossarm 4 and two secondary crossarms 5 can meet the requirements of ceiling load-bearing and electromechanical pipeline support, simplify the engineering design and construction process, and meet the load requirements of subway station halls or other public areas on the platform. Moreover, the steel base 6, L-shaped connector 7, fixed steel spring nut 8, main crossarm 4 and secondary crossarm 5 are all hot-dip galvanized to ensure the long-term stability of the device in high humidity and corrosive environments.
