[0002] In the process of building construction, it often happens that the construction of the started project is suspended or postponed due to various reasons. At this time, the exposed main steel bars of the constructed part will be exposed to the external atmospheric environment for a long time, and the exposed steel bars are extremely vulnerable to various damages. The erosion of unfavorable factors leads to a significant decline in the performance of the steel bars after restarting c

Example Embodiment

[0020] The anti-rust treatment method for the steel bars of the suspended construction project, the steel bars are all the exposed main steel bars after the shutdown; including the following steps:

[0021] 1) Derusting of steel bars;

[0022] Use a stiff brush to remove the floating rust on each steel bar one by one. When removing the rust, proceed from top to bottom, first long and then short. All steel bars are covered with protective caps of steel wire ends;

[0023] 2) Put heat shrink tubing on the outside of the steel bar;

[0024] After all the steel bars are derusted, put the heat-shrinkable sleeves you want to match with the steel bars according to different steel bar specifications. The top of the heat-shrinkable sleeve is 150~250mm higher than the top of the steel bar; then the heat-shrinkable sleeve at the root of the steel bar is melted with a blowtorch , So that the heat shrinkable tubing melts and wraps the steel bar;

[0025] 3) Pour steel anti-corrosion oil into the ga...

Abstract

The invention relates to a rust-proof treatment method for steel bars of suspended construction projects. The method includes steps of (1) performing rust removal on the steel bars; (2) sleeving the steel bars with heat-shrinkable sleeves; (3) pouring steel bar anti-rust oil in gaps between the heat-shrinkable sleeves and the steel bars; (4) pouring a concrete protecting layer. According to the invention, the complete method is adopted for protection of exposed steel bars and the durability is high, so that performance of the steel bars can meet construction requirements when the projects arereopened. Therefore, project quality is ensured and potential construction safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-rust treatment method for steel bars in suspended construction projects. Background technique [0002] In the process of building construction, it often happens that the construction of the started project is suspended or postponed due to various reasons. At this time, the exposed main steel bars of the constructed part will be exposed to the external atmospheric environment for a long time, and the exposed steel bars are extremely vulnerable to various damages. The erosion of unfavorable factors led to a significant decline in the performance of the steel bars after the resumption of construction, which could not meet the construction requirements and brought huge safety hazards to the construction of the building. At present, the protection of exposed steel bars in suspended and postponed construction projects is mainly covered by temporary protective mate...
