How to fill in the construction log after the foundation connecting beam is poured

1. Is it a framework structure and an independent foundation?

2. The foundation connecting beam is a pure foundation tie beam, and there are also foundation beams with load-bearing infill walls, right?

3. The support of the foundation connecting beam should be an independent foundation, not on the frame column base, right?

For the time being, answer how not to use the formwork, the foundation connecting beam is buried in the ground forever, and the bottom surface of the beam is not plastered, so it is not necessary to be so smooth; If the formwork is used, how to remove the beam bottom formwork? There's no need to throw some formwork into the soil and slowly rot! If the foundation tie beam is a tie beam and a foundation beam with an infill wall, the mid-span deflection deformation will implicate the infill wall to sit, which is not as good as the cushion, tamping slag, and tamping backfill.

The concrete subdivision of the foundation division.

Disclosure content: 1Material Requirements:

1: The cement is made of cement and cement produced by Yishui Cement Plant, and the cement should be inspected for its strength, stability and other indicators after entering the site, and it can be used only after it is confirmed.

2: The stone is made of 1 3cm stone produced by Sishan Shuangmiao Stone Factory, the stone grading should be uniform, the stone can not contain stone nitrate and soil and other sundries, and the strength can only be used after passing the test.

3: The sand is made of medium sand produced by Futuan River, and the mud content of the sand must meet the requirements, and it can only be used after passing the test.

2.When mixing concrete, it should be charged in the order of stones, cement and sand. The number of each loading shall not exceed 10% of the standard capacity of the mixing drum, and drinking water is suitable for mixing concrete, and the mixing time of reinforced concrete is generally 90 120 seconds per plate.

3.Before pouring concrete, the formwork, support, steel bar and embedded parts should be inspected and recorded. The garbage, soil and oil stains on the steel bars and other debris in the formwork should be cleaned up, the wooden formwork should be watered and moistened, but there should be no stagnant water, and the formwork should be coated with a separator.

4.The free height of concrete falling from a height should not exceed 2 meters. Before pouring the concrete of the vertical structure, the bottom should be filled with 50 100mm thick cement mortar with the same composition as the concrete.

5.The position of the construction joint should be set in the part where the shear force of the structure is small and convenient for construction, the column should be left with horizontal joints, and the beams and walls should be left with vertical joints.

6.Before the concrete strength is reached, the formwork and bracket shall not be stepped on or installed on it.

7.Concrete curing should be timely and effective. and at least 7 days of moisture preservation.

8.The maximum particle size of the coarse aggregate used in concrete shall not exceed one-quarter of the minimum size of the structural cross-section, and shall not exceed three-quarters of the minimum net distance between the steel bars.

9.Before pouring the concrete at the construction joint, it is advisable to lay a layer of cement slurry or mortar with the same composition as the concrete at the construction joint.

10.Allowable deviation and inspection standards of foundation concrete:

Axis displacement: 10mm

Elevation: 10mm

Cross-sectional size: 8mm 5mm

Surface flatness: 8mm

The plain concrete cushion is the bottom mold, the brick side mold (the stepped independent or strip foundation also needs to be lifted), the steel bar is tied, and the check is firm, and the concrete that has not yet been set is made inside and vibrated and compacted.

After the formwork is erected, the concrete can be poured after passing the acceptance.

What do you do every day, such as: digging the foundation earthwork, how many people, how many excavators are used, etc. What problems are found and how to deal with them! What materials were entered.

The technical indicators are the same every day or every month, according to the goals set by your unit, the content of production activities is the work process of a day, what time do you do, and then the work situation is written according to the planned engineering quantity formulated by your unit.

1.Let's go buy a construction log first.

2.The sample is as follows:

Construction logs. Construction unit: (will fill in) Project name:

1. Construction site: such as the eleventh layer of 1 2 A G shaft column steel bar 2 material entry and sampling.

3. Whether there are construction changes.

4. Which foreman did what technical disclosure.

5. What report has come out from the laboratory or what has been sent to be tested.

6. What notice does the company have or what requirements does Party A have for construction?

7. Labor arrangement.

The log is basically a flow account, that is, a detailed record of what happened on the construction site, the more detailed the better, just like a student writing a diary, and it can be understood by changing professional terms, as if it is to be handed over for quality inspection.

And you have to ask how many copies you have to write, and if you don't have enough to copy.

I don't know if it is the kind of construction that Bai refers to, does the owner of the du building want to ask the time of demolition? Concrete structures.

After the DAO is poured, it reaches a certain strength, and the mold can be removed inside.

Appearance. The date of dismantling of the formwork should be determined according to the structural characteristics and the strength of the concrete.

Demoulding deadline for cast-in-place concrete structures:

1. The non-load-bearing side formwork should be dismantled only if the concrete strength can ensure that its surface and edges and corners are not damaged due to the removal of the formwork;

2. The load-bearing formwork should be dismantled only after the concrete reaches the following strength (calculated according to the percentage of the design strength grade):

Plates and arches: spans of 2m and less than 2m 50

The span is greater than 2m to 8m 75

Beams (span of 8m and less than 8m) 75

Load-bearing structures (span greater than 8m) 100

Cantilever beams and cantilever plates 100

3. If the reinforced concrete structure is dismantled and partially loaded when the concrete does not reach the strength specified above, the strength of the structure under the actual load shall be calculated and reviewed.

4. The structure of the dismantled formwork and its support should be allowed to bear all the calculated loads only after the concrete has reached the design strength. It is not allowed to be overloaded during construction, and it is strictly forbidden to stack excessive building materials. When the construction load is greater than the calculated load, temporary support must be added after accounting.

Look at your formwork support plan, if reasonable, the speed can be as fast as one layer a week.

The floor slab must be at least 15 days, and the span is greater than 4m must be returned to the top.

Walls and columns are generally 8-10 hours in summer and winter in the winter.

Mould removal time.

What is the construction process? Generally, it will take 14 days later, and the foundation and beam will be after 28 days.

The concrete strength can only be reached before it can be put on the person.

Du, according to experience, concrete is poured at room temperature

After the next day, the DAO can be used to carry out the work such as pay-off. About the building.

Board stacking cannot be centralized.

should be scattered as much as possible. The steel bar binding work can generally be carried out two days after the concrete is poured.

In the construction process, a group of beams and plates can be made with the same condition test block, and the pressure can be applied after three days to determine its three-day strength.

Generally speaking, the strength of the concrete is reached.

I see what kind of work it is in that part.
