Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a screw hole blocking structure for a climbing frame wall support. Background Art

[0002] Climbing frames are becoming more and more popular in high-rise buildings and are widely used. The wall-mounted support of the climbing frame is fixed to the exterior wall of the building through high-strength screws. When pouring the exterior wall concrete, DN40 PVC sleeves need to be pre-buried in advance. Such pre-buried sleeves are large in number and diameter. If they cannot be sealed with high quality, they are very likely to cause a greater risk of leakage and moisture.

[0003] Traditional screw hole plugging usually requires expanding the hole, then chiseling out the internal PVC sleeve, plugging the dry cement mortar from the outside, and injecting polyurethane foam glue into the bolt hole from the inside after the cement mortar on the outside has finally set, leaving 20mm on the inside for the foam glue to be dried and hardened before plugging with cement mortar. This method has many construction processes and low efficiency. Although it can achieve a good plugging effect in the short term, it is very easy to have leakage problems in the later stage due to the poor durability of the foam glue. Utility Model Content
