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 |
