What are the concealed inspection batches to be done on reinforced concrete floors? 50

1. Concealed acceptance records and inspection batch acceptance records are two different concepts. Concealed Works Acceptance Record is a term used in the construction industry. It refers to the foundation, steel bar, water and electricity pipelines and other projects that need to be covered and covered.

The inspection batch is the basic unit of project quality acceptance. The conditions are the same and there are a certain number of materials, components or installation items during the construction process. If a sub-project needs to be inspected many times, then each inspection is called an inspection batch, and the industry stipulates:

The inspection parts of each inspection lot must be exactly the same. The inspection batch is only for inspection, not for evaluation.

2. The concealment that needs to be done on the reinforced concrete ground includes:

1) Acceptance record of concealed engineering of reinforcement installation;

2) Acceptance record of concealed engineering of ground leveling layer.

3. The inspection batch that needs to be done on the reinforced concrete floor includes:

1) Quality acceptance record of steel bar raw material inspection batch;

2) Quality acceptance record of steel processing inspection batch;

3) Reinforcement connection inspection batch quality acceptance record;

4) Reinforcement installation inspection batch quality acceptance record;

5) Concrete raw material inspection batch quality acceptance record;

6) Concrete construction inspection batch quality acceptance record;

7) Concrete structure appearance inspection batch quality acceptance record;

8) Ground screed inspection batch quality acceptance record;

9) Ground concrete cushion inspection batch quality acceptance record.

1. There are two concepts that should tell you first, the concealed acceptance data is not the inspection batch, which is two different kinds, the concealed acceptance record is the acceptance record of the construction process carried out before or after the construction of a construction process, and the inspection batch is the acceptance of the inspection of the engineering entity after the completion of a construction process. To put it simply, the concealed acceptance record is before construction, and the inspection batch is after the construction is completed. Here's the building infill wall to tell you the difference between the two.

2. The inspection batch of the building infill wall is the infill wall masonry engineering inspection batch quality acceptance record form, and the construction process is not concealed acceptance, and the reinforcement brick masonry engineering inspection batch quality acceptance record form and the reinforcement concealed structure acceptance record are required during the construction of the structural column. You need to pay attention to the construction time of these **.

Steel bars, water and electricity pipes, water and electricity pipe joints.

The formwork project has formwork installation and formwork removal inspection and acceptance records, and there is no concealed engineering inspection and acceptance record;

The steel bar engineering inspection has steel bar processing and steel bar installation inspection and acceptance records, of which the steel bar installation inspection record needs to be attached to the concealed engineering inspection and acceptance record (i.e., inspection application form + steel bar inspection record form + concealed engineering inspection and acceptance record);

Concrete engineering inspection is divided into concrete mix ratio, concrete construction, axis and size deviation, a total of three inspection batch acceptance, of which concrete construction inspection needs to be attached to the concealed engineering inspection and acceptance record (that is, concrete construction inspection application form + concrete construction inspection record form + concrete concealed engineering inspection and acceptance record).

It's really a rookie, haha, the so-called "hidden engineering" is not visible after the construction of the next process, and the most commonly used is the steel reinforcement project. The formwork project is a technical measure, which does not form an engineering entity, and it will be demolished after the construction of concrete, and the concrete construction can be seen after completion.

There is no formwork installation and concrete pouring, only the concealed inspection of the steel bar.

Steel bar installation, formwork installation, and concrete pouring are different construction processes.

If your concrete is to be concealed, then there should be a concrete concealment acceptance record. Templates don't have to be hidden.

Summary. Hello, the acceptance of the steel bar inspection batch and the acceptance of the concealed project should be carried out separately.

Should the acceptance of reinforcement inspection batch and concealed engineering be carried out separately? Why?

Hello, the acceptance of the steel bar inspection batch and the acceptance of the concealed project should be carried out separately.

"Hidden inspection" and "inspection batch acceptance" are both a kind of "acceptance" of the inspected object. In the national acceptance specification, "acceptance" and "inspection" are obviously not the same in concept. "Acceptance" cannot be carried out unilaterally by the construction unit itself, and must be participated by the supervision or construction unit other than the construction unit, which is a kind of impartial confirmation or recognition, while the "inspection" can be carried out unilaterally by the construction unit itself.

Although "hidden inspection" and "inspection batch acceptance" both belong to the category of acceptance, the objects and roles they play are different. Inspection batch acceptance is the most basic level of all acceptance, that is, the acceptance of all other levels (sub-items, divisions, unit projects, etc.) is based on the acceptance of circular inspection batches, and all parts and processes of the project should be classified into an inspection batch acceptance without omission. The acceptance of concealed works is only for the parts of the project that will be concealed.

Although there are many hidden projects in construction, there are still a large number of non-hidden parts in a construction project. Therefore, the two are not the same, and the acceptance of "hidden inspection" and "inspection batch" should be carried out separately.

Thank you. 4) In the process of concrete pouring construction, whether the personnel of the side station can be responsible for the on-site sampling and production of test blocks at the same time.

Forensic sampling work? Why?

Good. In the process of concrete pouring construction, the bystander personnel can also be responsible for the on-site sampling and production of test blocks.

There are two kinds of steel engineering inspection batches: 1. Steel bar processing and production quality inspection batches; 2. Steel bar installation quality inspection batch.

For the concealed acceptance of steel bars, the acceptance record of the concealed project should be filled in and attached to the "Steel Installation Quality Inspection Batch" form.

The acceptance criteria for concealed inspection of steel engineering construction are:

1.Check the longitudinal stressed steel bar according to the construction drawing, and check the variety, diameter, quantity, position, spacing, shape and size of the steel bar.

2.Check whether the thickness of the concrete protective layer, structural reinforcement and embedded parts meet the requirements.

3.Check the steel orange joints: such as lashing laps, check the lap length, joint position and quantity (staggered length, joint percentage), welded joints or mechanical connections, to check the appearance quality, whether the mechanical properties test of the sampling specimen meets the requirements, the position of the joints (staggered from each other), and the quantity (joint percentage).

4.Do a good job of recording the dust of the concealed steel project.

Against Yuan Minhong tick big square orange book over and over again clothes clothes clothes also take shed in line with and vu will not be prosperous to prevent typhoons.

Answer: Before pouring concrete, the acceptance of the concealed steel reinforcement project should be carried out, which includes:

1. The variety (type), specification, quantity, location, etc. of longitudinal tensile reinforcement;

2. The connection mode, joint position, number of joints, percentage of joint area, etc.;

3. Varieties (types), specifications, quantities, spacing, etc. of stirrups and transverse reinforcements;

4. The specification, quantity, and location of embedded parts.

The grade, specification, quantity, longitudinal and horizontal steel bar connection method, seismic grade, steel bar raw material retest experiment, steel bar welding test results are qualified, whether rust removal, construction basis, etc.

Reinforcement engineering is an important sub-item in the construction of concrete structures, and it must be reported as a concealed project when reporting for inspection.

Acceptance records. However, the general concealed engineering belongs to the process of materials, and it can not be intuitively inspected after the acceptance of the acceptance and pouring of the cover is missing, and can only be detected by the instrument. At this time, during the re-inspection, your Sun Xian's concealed project acceptance record is the most favorable verification information.

Same as formwork engineering.

In the same way, when the project is completed and the completion data is sorted out, these materials can be put forward without filing. However, the raw materials, welding and other materials of the steel bar should be archived and stored as permanent data.
