Henan Mingda Zhanggong: 132-03888-163 structural column head sanding problems in concrete engineering: structural column head sanding.
As long as the construction novice gets the construction scheme of planting steel bars, the construction can be carried out more easily according to the scheme.
Making the construction scheme of planting steel bars with high economy and up to standard feasibility in advance can ensure that the construction operation is more convenient.
Henan Mingda Zhanggong: 132-03888-163 for members with the same strength grade, when the following provisions are met, the strength of structural solid concrete can be judged as qualified: (1) the arithmetic mean value of compressive strength of three core samples shall not be less than 88% of the concrete strength grade value required by the design; (2) The small value of the compressive strength of the three core samples shall not be less than 80% of the concrete strength grade required by the design.
Cause: the ponding of structural column head formwork is not cleaned before pouring concrete.
Handling opinions: contact the design institute to issue the handling scheme and handle it according to the scheme…
Undertake the reinforcement and transformation of building structures such as factories, shopping malls, office buildings, hotels and schools, improve the load-bearing reinforcement projects, and provide integrated services of house quality and safety inspection and appraisal, reinforcement design and construction.
Specification requirements: the appearance quality of cast-in-situ structure shall not have serious defects.
The reinforcement planting construction shall be carried out according to the reinforcement scheme.
Henan Mingda is a company integrating structural reinforcement, design, testing, construction and construction.
If the reinforcement scheme is not formulated, it is likely to be anxious in the construction link, especially when the construction novice is planting reinforcement, once the construction veteran is not around at any time, it is likely to be unable to carry out the next construction operation.
