Description

Technical Field

[0001] The present invention belongs to the field of mechanical and electrical installation in construction projects, and particularly relates to a manufacturing and installation method for electrical modularization, which is applicable to the assembly of large-volume modular H-steel bases. Background Art

[0002] In mechanical and electrical installation, there are generally bridge installation, busbar installation, pipeline installation, etc. And these devices are all hoisted at a high position in the factory building, generally at least installed at a height of 4 - 5 meters. Inevitably, this requires working at heights, increasing the danger to construction workers. And various devices will be separately made with support brackets, resulting in numerous through-thread rods on the top of the factory building, which not only affects the overall aesthetics inside the equipment installation layer but also easily blocks the passage of air ducts and larger-diameter pipelines. When making fixed brackets, there will be welding operations (hot work operations), which will bring the risk of fire to the construction site. Summary of the Invention

[0003] The purpose of the present invention is to provide a manufacturing and installation method for electrical modularization, which reduces the working at heights of workers, does not require hot work operations, and the entire modular unit is installed on the column corbels, without the need to drill through-thread hangers on the factory building roof, and the upper space can be freely piped. The present invention is achieved through the following technical solutions: A manufacturing and installation method for electrical modularization, including the following steps: S1. Assembling modular supports; S2. Assembling the overall modular equipment; S3. Segmentally transporting the overall modular equipment to the site and then assembling it into an overall system; S4. Lifting, moving, and lowering the overall system upward and landing it on the corbels and then installing it.

[0004] Preferably, in S1, C-shaped steel supports are installed on the H-steel base to form a complete modular support.

[0005] Preferably, in S2, pipeline equipment and bridges are installed and fixed on the C-shaped steel supports to form the overall modular equipment.

[0006] Preferably, in S4, it is divided into three lifts. S401. Lifting the overall system to the set equipment installation height, placing H-steel pads under the overall system, and landing the overall system on the H-steel pads; S402. Lifting the overall system and the H-steel pads simultaneously and landing the overall system on a movable lifting trolley; S403. Lifting the movable lifting trolley and the overall system to the set height, and landing the overall system on the shock pads above the corbels and then fixing it to complete the installation of the entire overall system.

[0007] Advantages of the present invention: The bridge, busbar, waterproof cover plate, and pipeline are all installed on the ground, which avoids high-altitude operations and ensures the safety of construction workers; modularization is all manufactured in the processing yard outside the factory building, greatly reducing the potential fire hazards at the construction site; the number of personnel invested in the construction site is reduced, making management more convenient; modular production ensures the unity of quality; through external production, large-scale batch production can be achieved; the use of through-thread suspenders in the factory building is reduced, making the upper space of the factory building more optimized and unobstructed. Specific implementation method

[0008] A method for manufacturing and installing electrical modularization includes the following steps: S1. Assembling modular brackets; S2. Assembling the overall modular equipment; S3. After transporting the overall modular equipment to the site in segments, assembling it into an overall system; S4. Lifting, moving, and lowering the overall system upward and landing it on the corbel and installing it.

[0009] Preferably, in S1, the C-shaped steel bracket is installed on the H-shaped steel base to form a complete modular bracket.

[0010] Preferably, in S2, pipeline equipment and bridges are installed and fixed on the C-shaped steel bracket to form the overall modular equipment. The bridge, busbar, waterproof cover plate, and pipeline are all installed on the ground, which avoids high-altitude operations and ensures the safety of construction workers.

[0011] Preferably, in S3, before transportation, the pre-assembled overall modular equipment is disassembled into standard segmented modules, each segment is transported to the construction site separately, and then the segmented modules are assembled into an overall system again, and equipment such as busbars, waterproof cover plates, and wire troughs are installed on the ground.

[0012] Preferably, in S4, it is divided into three lifts. S401. The first lift: Lift the overall system to the set equipment installation height, place H-shaped steel pads under the overall system, and lower the overall system onto the H-shaped steel pads. For example, use 14 hoisting machines to lift the overall system to a height of 500 mm at the same time, then place H-shaped steel pads with an application height of 350 mm under the overall system, and lower the overall system onto the 350 mm H-shaped steel pads;

[0013] S402. The second lift: Lift the overall system and the H-shaped steel pads simultaneously, and lower the overall system onto the movable mobile lifting trolley. For example, use 14 hoisting machines to lift the 350 mm H-shaped steel pads to a height of 2000 mm at the same time, push the movable mobile lifting trolley with a total height of 1950 mm under the overall system, lower the overall system onto the lifting trolley, and remove the 350 H-shaped steel pads;

[0014] S403. Lift the mobile lifting trolley and the overall system to the set height, and land the overall system on the shock pads above the corbels and fix it to complete the installation of the entire overall system. For example, if 14 hoists are used to lift the trolley simultaneously, lift the overall system to a position 300 mm above the installation height and stop lifting. At the same time, install the corbels and shock pads on the columns below the overall system. Finally, land the module on the shock pads above the corbels and fix it to complete the installation of the entire overall system.

[0015] The standardized production of the overall system enables batch production, improving construction efficiency; the installation of mechanical and electrical equipment (bridge trays, busbars, pipelines, etc.) on the ground reduces high-altitude operations and the risk of falling from heights; there is no need for hot work such as welding, eliminating fire hazards; the number of on-site construction personnel is reduced, facilitating on-site management.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced without departing from the spirit and scope of the present invention, and the appended claims are intended to cover such modifications or equivalent replacements that fall within the spirit and scope of the present invention.
