Check to ensure proper reinforcement location during the construction

During the construction process, many of these impacts may pick position was reinforced acceptance before pouring concrete over reinforcement as travel, reinforced shoulder dress squashed beef in the pillow, the concrete dress when Pi Baseball dress in reinforcement, mechanical shock bruise reinforced frames, broken pieces of Statistics, Statistics bias pieces.

The permanent workers to ensure correct these errors is required. No direct iron workers pouring concrete failure will lead to deplorable that the absence of manipulation. Lack of direct workers and shuttering workers not directly edit the reinforced concrete should proceed.

The structure is of reinforced concrete bearing structure is important to ensure the functionality and sustainability of the structure should be witnessed by consulting engineers to ensure the quality of the contractor’s work is essential.

The inspection can refer to the following table:

Check Items Check method Requirement of checking Check Frequency
1 2 3 4
Reinforced Materials According to delivery notes, certificates, catalogs, visual observations There are catalogs, certificates and goods delivered catalogs Every time delivery
Testing the rebar diameter or weight to the nominal diameter of the valve towers Synchonize cross-section dimensions, correct diameter required Every time delivery
Test following Vietnam Construction Regulation 197-85 and 198-85 Ensuring the design requirements Before doing
Outside observers steel bar By eyes Clean surface, not dented, crushed Before doing
Observed cutting, bending rebar By eyes Ensure technical processes During doing
 Bending steel bar By rulers Deviations must be smaller than some specified data Just take 5 bar to 100 bar checks
Welding work Reinforced Welding equipment Đảm bảo các thông số Before welding, and every 3 months 1 time
The welders level meet welding test samples The welder level following regulation Befor welding
Welding equipment Make sure the parameters Before welding, and every 3 months 1 time
The welders level meet welding test samples The welder level following regulation Trước khi tiến hành hàn
With the naked eye and measure Welds meet data requirements When welding is finished and acceptance
The experiment samples Make sure the samples have not reached tieuNeu just have to check back with double the number of samples For every 100 welds 3 samples taken to test strength
Ultrasonic testing following Vietnam Construction Regulation 1548-85 Ensure quality When in doubt or when needed
Steel standby and reservation details available Determine the location, size and number of appropriate measures Meets the requirements of the design Before concreting
Connect reinforcement Observations with the eyes, measured by eyes Make sure the connection During and after the reinforcement frame
Installation of reinforced Observations with the eyes, measured by eyes Technique.We erection right type, location and size deviation Kesai properly set within the specified Complex process of structural reinforcement and the acceptance
Concrete spacer By eyes or rulers Ensure the regulation Complex process reinforced
Thickness of reinforced concrete protection Check the power follwing Vietnam Construction Regulation 240-2000 In accordance with regulations for each type of structure Erection process and acceptance
Change reinforced According to calculations When difficulties should instead Prior to the reinforced
