Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically relating to a sealing wall device and construction method for a prefabricated equipment transportation portal. Background Technology

[0002] Large-scale projects such as rail transit engineering, public buildings, residential communities, and substations typically require the installation of large indoor equipment. To meet the daily maintenance needs of this equipment, equipment transport access points are necessary. These access points usually require sealing walls to ensure operational safety and facilitate equipment maintenance. Currently, common sealing solutions for equipment transport access points include constructing temporary sealing walls and using roller shutter doors.

[0003] The advantage of using a temporary sealing wall is its structural stability, which reduces the likelihood of operational safety accidents. However, it has two disadvantages when opening equipment transport access points:

[0004] First, the dismantling and reconstruction process takes a long time, which leads to a prolonged construction period and increases operational safety risks.

[0005] Secondly, the construction process generates a large amount of dust, sparks, and construction waste, which poses unpredictable risks to equipment in the equipment room that does not need to be replaced, equipment in adjacent equipment rooms, pipelines in the construction area, and other sensitive equipment that is in use.

[0006] The advantages of the roller shutter door sealing solution are a shorter construction time, lower safety risk during construction, less dust, no sparks or construction waste generated during construction, and no personnel unrelated to equipment installation, dismantling, and commissioning allowed on-site, thus avoiding unpredictable risks to other equipment. However, its disadvantages are also quite obvious, including the following two:

[0007] First, the structural strength is insufficient. Because the roller shutter door is a steel structure, there is a gap between the door and the wall. During normal operation, it is affected by positive and negative wind pressure, and the door and the wall collide continuously, which not only causes a lot of noise, but also damages the door. At the same time, steel roller shutter doors contain a large number of moving parts, which not only require long-term maintenance to ensure that they meet their functional requirements, but also have a shorter service life than fixed structure sealing solutions, resulting in insufficient structural durability.

[0008] Secondly, it is impossible to simultaneously meet the requirements for fire resistance, smoke prevention, and strength. Because the materials used in steel roller shutters cannot meet the fire resistance requirements of fire-resistant roller shutters, and fire-resistant roller shutters cannot meet the strength requirements of steel roller shutters, it is impossible to choose a roller shutter that satisfies both strength and fire / smoke prevention requirements to seal the equipment transport opening.

[0009] Therefore, a new technology is needed to solve the problems of unsafety and inconvenience in opening and sealing existing sealing walls. Summary of the Invention

[0010] To address the aforementioned problems in the prior art, this invention provides a sealing wall device for prefabricated equipment transport openings, which is convenient for sealing and opening operations, and structurally safe and stable during sealing.

[0060] In one embodiment, the top surface 7 is provided with a lifting part 15 for providing a fulcrum for the rope. In this embodiment, the top surface is provided with two lifting parts.

[0061] A construction method for a sealing wall device for a transport opening of prefabricated equipment, the construction method including a sealing method and an opening method, wherein the sealing method includes the following steps:

[0062] SA1. Tie ropes to the lifting part 15 on the top of the sealing block 1, and connect them to a small crane or winch through the lifting part 15 on the top surface body 6.

[0063] SA2. Tie a rope to the lifting part 15 on the side of the sealing block 1, with the other end of the rope controlled by the operator.

[0064] SA3. Use a small crane or winch to lift the sealing block 1. The operator adjusts the horizontal position of the sealing block 1 by using the rope tied to the side lifting part 15 of the sealing block 1, so that the sealing block 1 falls into the groove 43 of the structural column 4 in the vertical direction.

[0065] SA4. Repeat steps SA1 to SA3 until the sealing block 1 is sealed up to the bottom of the hanging wall 5.

[0066] SA5, apply fireproof putty layer 9 and other grouting materials.

[0067] The opening method includes the following steps:

[0068] SB1. Remove the fireproof sealant layer 9 and other grouting materials;

[0069] SB2. Tie ropes to the lifting part 15 on the top of the uppermost sealing block 1, and connect them to a small crane or winch through the lifting part 15 on the top surface 6.

[0070] SB3. Tie a rope to the lifting part 15 on the side of the uppermost sealing block 1, with the other end of the rope controlled by the operator.

[0071] SB4. Use a small crane or winch to lift the sealing block 1 so that the sealing block 1 is vertically removed from the range of the groove 43 of the structural column 4;

[0072] SB5. The operator adjusts the horizontal position of the sealing block 1 by using the rope tied to the lifting part 15 on the side of the sealing block 1, so that the sealing block 1 moves away from the range of the groove 43 of the structural column 4 in the horizontal direction.

[0073] SB6. Use a small crane or winch to place the sealing block 1 onto a trolley on the ground and push it away from the equipment transport channel;

[0074] SB7. Repeat steps SB1 to SB6 until all sealing blocks 1 are lifted off.

[0075] The advantage of this invention is that the sealing block 1 achieves vertical stability through its own weight and the interlocking action between the groove structure 13 and the convex structure 14 of each sealing block 1. Furthermore, the displacement is constrained by the groove 43 of the structural column 4, ensuring the entire sealing wall device structure remains stable. Since the side facing the equipment room or the track area of ​​the rail transit project does not have small components, the risk of parts being lost or falling into the track area is reduced.

[0077] Furthermore, the wall device of the present invention is relatively easy to install and dismantle, involves almost no destructive construction, has a short construction time, and low operational risk. Each sealing block 1 of the present invention takes approximately five minutes to hoist. Based on a 3m long and 3m high equipment transport opening, a total of fifteen sealing blocks are needed, and the hoisting can be completed in approximately seventy-five minutes. After the sealing is completed, the entire device can be put into practical use with low operational risk (the specific number of sealing blocks required depends on the size of the equipment transport opening being sealed).

[0078] In addition, the sealing block 1 is reusable, energy-saving and environmentally friendly, and its maintenance is relatively simple.

[0079] Finally, the sealing block 1 is easy to mass-produce, which reduces the unit cost while ensuring construction quality.
