Description

Technical Field

[0001] This invention relates to the field of decoration and renovation technology, specifically a method for secondary piping repair in ALC wall panels. Background Technology

[0002] ALC wall panels are hollow partition boards, offering advantages such as low price, easy construction, and low cost. However, they also have many disadvantages: ALC wall panels are prone to deformation due to temperature changes, and their hollow structure affects their load-bearing capacity; for interior decoration, the grooving for secondary piping in ALC wall panels is an important construction procedure.

[0003] After grooving the ALC wall panel, the dust inside the groove needs to be cleaned and then moistened with water. However, the current method of treating the groove is mostly to have workers first manually clean it with a rag and then spray water. This not only increases the labor intensity of the workers, but also makes it difficult for workers to clean and spray water when the groove is high, which greatly affects the efficiency of construction. Summary of the Invention

[0004] The purpose of this invention is to provide a construction method for secondary piping trench repair in ALC wall panels, which aims to solve the problem that in the existing technology, the treatment of cable trenches mostly involves workers first manually cleaning them with a rag and then sprinkling water on them.

[0008] Step 3: Cleaning and wetting the cable trays: Clean the dust from the cable trays and wet them with water.

[0009] Step 4: Laying, adjusting, and fixing the conduit: The bends in the conduit must be bent with a matching bend spring, and the bend must meet the specifications and not be less than 90 degrees.

[0010] Step 5: Fill and compact crack-resistant mortar in layers: After ensuring that the distance between adjacent pipes is greater than 10mm and there are no other quality problems, fill and compact crack-resistant mortar in layers.

[0011] Step Six: Cable Tray Finishing: After cleaning the pipes, confirm that the pipeline is unobstructed, promptly thread the cable, and plug the pipe openings, box openings, and enclosure openings to strengthen the protection of the finished piping;

[0012] Step 7: Reinforcement with mesh: Use fiberglass mesh for reinforcement, with a mesh weight of not less than 180g / ㎡;

[0039] Step 4: Laying, adjusting, and fixing the conduit: The bends in the conduit must be bent with a matching bend spring, and the bend must meet the specifications and not be less than 90 degrees.

[0040] Step 5: Fill and compact crack-resistant mortar in layers: After ensuring that the distance between adjacent pipes is greater than 10mm and there are no other quality problems, fill and compact crack-resistant mortar in layers.

Under the weight of the water spray unit 4, it can drive the rotating brush 2 to move from top to bottom, thereby cleaning the trench during the movement of the rotating brush 2. When the water spray unit 4 is raised and lowered, it can simultaneously drive the mounting unit 3 to swing left and right, thereby adjusting the angle of the water spray from the water spray unit 4 and the angle of the rotating brush 2. The mounting unit 3 is provided with a drive unit 5. When the mounting unit 3 is raised and lowered, it can drive the rotating brush 2 to rotate and squeeze the water in the water spray unit 4, thereby spraying water into the trench.

[0048] like Figure 5-7 As shown, the water spray unit 4 includes a water tank 41 fixedly connected to the U-shaped frame 33. Two nozzles 42 are installed on the side of the water tank 41 near the rotating brush 2, and the two nozzles 42 are located above and below the rotating brush 2 respectively. Water in the water tank 41 can be sprayed out through the nozzles 42 to humidify the groove. An S-shaped groove 43 is provided on the side of the support rod 12 near the water tank 41. A sliding rod is slidably connected in the S-shaped groove 43, and the sliding rod is hinged to the water tank 41. When the water tank 41 moves downward under the action of gravity, the sliding rod can slide in the S-shaped groove 43, thereby causing the water tank 41 to swing back and forth. When the water tank 41 swings, it can simultaneously drive the rotating brush 2 and the nozzles 42 to swing left and right.

[0049] like Figure 7 As shown, the drive unit 5 includes a rotating shaft 51 disposed within the loop frame 33. The end of the rotating shaft 51 near the rotating brush 2 is fixedly connected to the rotating brush 2.

A rack 53 is fixedly connected inside the mounting frame 32, and the rack 53 meshes with the first gear 52. When the loop frame 33 moves, it can drive the first gear 52 to move along the rack 53, thereby driving the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, it can drive the rotating brush 2 to rotate and clean the groove. A squeezing part is provided inside the water tank 41 to squeeze the water in the water tank 41, thereby discharging the water through the nozzle 42 to spray water and humidify the groove.

[0050] like Figure 7 As shown, the extrusion section includes a small gear 54 fixedly connected to the surface of the rotating shaft 51, and the small gear 54 is located inside the water tank 41. Two lead screws 56 are rotatably connected inside the water tank 41. A large gear 55 is fixedly connected to the surface of the lead screw 56, and the large gear 55 meshes with the lead screw 56. An extrusion plate 59 is sleeved on the surface of the rotating shaft 51, and the extrusion plate 59 is threadedly connected to the lead screw 56. When the rotating shaft 51 rotates, it can drive the small gear 54 to rotate. Then, the rotation of the small gear 54 will drive the large gear 55 to rotate. Then, the rotation of the large gear 55 will drive the lead screw 56 to rotate. When the lead screw 56 rotates, it can drive the extrusion plate 59 to move, extruding the water in the water tank 41 and spraying it out through the nozzle 42.

[0051] like Figure 2-4 As shown, vacuum suction cups 6 are fixedly connected to the side of the two fixing blocks 31 closest to the wall, which are used to fix the fixing blocks 31 to the wall.

[0052] Working principle: First, move the support frame 1 to a suitable position so that the rotating brush 2 is located inside the wire trough. Then, adjust the mounting part 3 to a suitable height according to the height of the wire trough and make the mounting part 3 parallel to the wire trough so that the rotating brush 2 can move along the wire trough. Next, inject water into the water spraying part 4 and adjust the rotating brush 2 to the top of the wire trough. Under the action of gravity, the water spraying part 4 and the rotating brush 2 will move downward along the wire trough. During the movement, the water spraying part 4 can spray water on the wire trough through the set drive part 5, and the rotating brush 2 will rotate to clean the wire trough. This makes it easy to process the wire trough without manual processing by workers, which not only reduces the labor intensity of workers, but also effectively improves construction efficiency.
