Description

Technical Field

[0001] The utility model belongs to the field of building construction. Specifically, the utility model relates to a device for adjusting the spacing of main bars and the protective layer of epoxy steel bars for pier shafts. Background Art

[0002] When building cross-sea bridges in a marine environment, the seawater has strong corrosiveness. To prevent the steel bars from rusting, extend the service life of the steel bars, and improve the stability and safety of concrete structures, the design requirements for cross-sea bridges are that epoxy-coated steel bars should be used below the splash zone. For the construction of steel bar binding for pier shafts, the conventional process technologies are as follows: 1. Weld bracing or diagonal bracing on the main bars to adjust and control the protective layer and the spacing of steel bars; 2. Use ordinary steel bars to make positioning bars and erection bars to control the protective layer and the spacing of steel bars, and tie them firmly on the main bar positioning bars.

[0003] In a published specification with a patent number of 202210529144.0 and a publication date of September 2, 2022, a new anti-corrosion construction process for marine bridge concrete structures is disclosed. The durability of the concrete structure of bridges in a marine corrosion environment not only depends on measures such as epoxy steel bars, high-performance marine concrete, and optimized design of the steel bar protective layer, but also requires some auxiliary measures. The utility model provides a construction process of external spraying of silane impregnation. In terms of ensuring construction safety, especially in the surface treatment details to ensure the spraying effect, steps such as the repair treatment of the tie rods for formwork construction, the repair treatment of cracks, the treatment of surface looseness and pollution, and the regulation of surface dryness can better ensure the spraying effect, and verify the spraying effect through the detection indexes of the water absorption rate of core samples taken from the entity, the impregnation depth, and the reduction effect of chloride absorption content. The anti-corrosion process of the utility model forms an organic whole with conventional measures, improves the bridge durability anti-corrosion measures during the construction period, and thus effectively protects the durability of cross-sea bridges during the trial period.

[0004] In the prior art, the design usually requires the use of epoxy-coated steel bars below the splash zone. Epoxy-coated steel bars are prohibited from being welded during construction, so it is impossible to weld diagonal bracing or bracing on the main bars to control the size of the protective layer. And using ordinary steel bars to make positioning bars and erection bars can control the size of the protective layer and the spacing of steel bars, but it will cause a large amount of steel bar loss.
