Description

Buckle formula outer wall pre-buried sleeve structure Technical Field The utility model relates to the field of external wall embedded pipes, in particular to a buckle type external wall embedded sleeve structure. Background The external wall embedded pipe refers to a pipeline or a sleeve which is embedded in a concrete structure in advance in the construction stage of the external wall of a building and is used for later installation of pipelines such as water supply and drainage, fuel gas, ventilation, electric and the like. The core purpose of the pre-buried pipeline or sleeve is to ensure accurate positioning and reliable sealing when the pipeline penetrates through the wall and reduce damage to the building structure. However, in the conventional construction technology, the outer wall embedded sleeve is mostly welded or fastened by steel bars, and when the wall column template is assembled and concrete is poured, the sleeve is easily subjected to mechanical disturbance of vibration operation to generate the conditions of deflection, downhill slope and the like. According to statistics, the process sleeve installation qualification rate is only 75% -85%, and about 20% of sleeves have the phenomena of axis deviation exceeding 10mm, end parts separating from wall surfaces or reverse slopes and the like after the die is removed, and the phenomena require additional cost to put in remedial measures such as chiseling repair and secondary perforating, and the repair operation is easy to destroy the compactness of the concrete structure, so that leakage hidden danger is aggravated.
