Abstract

The invention discloses a construction engineering embedded exposed steel bar rust-proof device which comprises a rust-proof sleeve, a sealing device and an air suction hole. One end of the rust-proof sleeve is provided with a pipe opening and sleeves an outer wall of an exposed steel bar through the pipe opening, the air suction hole is formed in a side wall of the rust-proof sleeve and only allows gas to flow out of the rust-proof sleeve through the air suction hole, the sealing device is an elastic pipe fitting with two ends open, and the two ends of the sealing device respectively sleeve the rust-proof sleeve and an outer wall of the exposed steel bar and form a sealed sealing surface. The construction engineering embedded exposed steel bar rust-proof device solves the problem that due to the fact that exposed parts of existing construction engineering concrete joint embedded steel bars are exposed to air and subject to the influence of rain, sunshine and damp air, the exposed parts rust easily and construction durability is weakened. The steel bar rust-proof device prevents the rain and the damp air from influencing the steel bar and prevents and slows down corrosion of the construction engineering embedded exposed steel bar.

Description

technical field [0001] The invention belongs to the field of construction engineering devices, and in particular relates to a construction engineering pre-buried exposed steel bar rust prevention device. Background technique [0002] In the design and construction of reinforced concrete structures in construction projects, in order to eliminate problems such as structural cracks caused by shrinkage and deformation during the hardening process of concrete, deformation joints and post-cast concrete strips are usually set at regular intervals in reinforced concrete structures. Pre-embedded steel bars to ensure the integrity of the concrete structure. The exposure time of pre-embedded steel bars in deformation joints is determined according to the deformation requirements of structural concrete and construction technology, generally ranging from 30d to 90d, and some are even longer, with an interval of more than 1 year. These exposed steel bars rust quickly in the air, and as t...
