Description

Technical Field

[0001] The invention relates to the technical field of high-rise building construction, in particular to a high-rise roof cantilever plate perforation repair structure and a construction method thereof. Background Art

[0002] At present, in high-rise buildings, in order to reflect the aesthetic effect of the building, most of them are equipped with cantilever panels around the top roof, and the width of the cantilever panels is relatively wide. When decorating the exterior wall, the traditional construction method is to install a hanging basket, but because the cantilever panel is wide, the length of the forearm of the hanging basket cannot meet the use requirements, which is bound to cause difficulties in the installation of the hanging basket. In order to ensure the safety of the installation and use of the hanging basket, it is necessary to drill holes on the cantilever panel for the steel wire rope of the hanging basket. However, after the hanging basket and the steel wire rope are removed, the repair construction of the cantilever panel perforation becomes a problem. In general, the traditional construction method requires construction workers to climb high to repair, but because it is a high-altitude operation, there are great safety hazards when the construction workers operate, the quality of the holes after repair is poor, the durability is low, and it is easy to leak, which affects the appearance of the building, and the cost is also high.

[0015] (3) The lower sealing gasket is mounted on the perforated bolt from top to bottom and inserted into the perforated hole of the cantilever plate until the lower sealing gasket is in close contact with the head of the perforated bolt, thereby sealing the bottom of the perforated hole of the cantilever plate;

[0016] (4) Fill the plugging slurry from the top of the cantilever plate perforation into the cantilever plate perforation until the level of the top of the plugging slurry is consistent with the level of the bottom of the cantilever plate perforation slot;

[0017] (5) After the plugging slurry solidifies and meets the strength requirements, cut off the traction line at the top of the perforated bolt, then put the upper sealing gasket on the perforated bolt and place it at the bottom of the slot, and then thread the locking nut on the perforated bolt from top to bottom and make close contact with the upper sealing gasket, so that the upper sealing gasket seals the part below the perforated slot of the cantilever plate;

[0018] (6) Use waterproof mortar to fill the slotted part of the cantilever plate tightly to form a waterproof sealing block. The top of the waterproof sealing block is flush with the top of the cantilever plate.

[0019] After the top of the cantilever plate perforation is slotted, the entire hole of the cantilever plate perforation is cleaned, and the slot bottom is leveled with leveling mortar to make the slot bottom flat and facilitate close contact between the upper sealing gasket and the slot bottom.
