Seek concrete construction plan, key points of concrete construction plan

Kiss! Hello, happy to answer your <>

The main points of the pro-concrete construction scheme are as follows:1** way of concrete:

The selection of ready-mixed concrete batching plant and the technical requirements for mixing concrete (the selection of initial and final setting specimens, admixtures, ammonia odor control, slump loss control and on-site treatment measures in different seasons should be the focus); ** method of concrete of different strength; On-site concrete horizontal and vertical transportation methods and tools. 2.Concrete pouring:

pouring direction, pouring method, pouring time of large-volume concrete; control measures for the pouring height of concrete; Control method for roof concrete elevation, thickness and flatness; construction joint retention method and cleaning; the division of pouring range between concrete of different strength grades; wall concrete pouring method and pouring time; concrete surface treatment method; Post-pouring belt construction requirements and construction time. 3.Concrete curing:

The method and time of concrete curing, for large-volume concrete, the curing time and method must be adjusted according to the temperature measurement. Hope mine can help you <>

Do you have any other questions?

Concrete pouring refers to the process of pouring concrete into the finger mold until plasticization, the concrete construction team is generally called concrete or concrete construction, the terminology is collectively called concrete pouring, it can also be called pouring concrete, they both mean the same, but as our engineering team, we still prefer to call it concrete. Let's take a look at the construction process with Tuzhuhu.

1. What materials need to be prepared for the construction of concrete?

In our long-term concrete construction experience, the materials that are generally needed are cement, sand, gravel, and concrete admixtures.

It should be noted that cement, sand, gravel, concrete admixtures, etc. should meet the provisions of the relevant standards, as well as the design requirements of construction drawings.

Second, the operating conditions.

1. The formwork, steel bars, embedded iron parts and pipelines of the pouring concrete layer have all been installed, and they have passed the inspection and met the design requirements, and the concealment and pre-inspection procedures have been completed.

2. The shelves and walkways for pouring concrete have been erected and passed the inspection.

3. Cement, sand, stone and admixtures have been inspected to meet the requirements of relevant standards, and the concrete mix ratio notice has been issued for the test.

4. The electronic measuring instrument is accurate and flexible after inspection, and the vibrator (rod) is in normal operation after inspection.

3. Concrete construction technology.

1. According to different construction sites and construction sites, formulate different concrete construction plans, first of all, before pouring concrete, please ensure that the garbage, soil, sawdust, oil stains and other debris on the steel bars in the formwork are cleaned up, and the experience is qualified and the concealed procedures are done before pouring concrete.

2. Pouring concrete needs to be tested for slump, whether it meets the design requirements, if you don't understand, please check the concrete slump test here, the following is the concrete slump table:

Note: In the process of concrete pouring, arrange a person to be responsible for observing the formwork, steel bars, etc., when the deformation and displacement are found, the pouring should be stopped immediately, and the concrete that has been poured should be solidified and trimmed intact before continuing to pour concrete. Secondly, a person should be assigned to be responsible for observing the pipes to prevent gambling pipes or pipe bursts.

The concrete that has been poured Huyou should be properly watered and cured within 12 hours, and the silver should be watered and raised at normal temperatures not less than twice a day, and at the same time not less than 7 days, and the waterproof concrete should not be cured for less than 14 days.

Hello, I am glad to answer for you: how to write the home improvement concrete pouring construction plan as follows: (1) Operation preparation 1 Before pouring, the garbage, soil, wood and other debris in the formwork and the oil stain on the steel bar should be cleaned, and check whether the protective layer cushion block of the steel bar is well mated, and whether the protective layer cushion block of the steel bar meets the requirements of the specification.

2 Water the formwork before pouring to make it moist. 3. The loose concrete and the weak layer of concrete in the construction joint have been removed and cleaned, exposing the stones, and watering is moist and there is no clear water. (2) General requirements for concrete pouring and vibrating 1 The use of pumped concrete, the free falling height of concrete from the pump mouth shall not exceed 2m, and measures must be taken when the pouring height exceeds 2m, such as using string barrels or slips.

2. The use of plug-in vibrating pump should be quickly plugged in and slowly unplugged, and the insertion points should be evenly arranged, moved point by point, and carried out in sequence, without omission, so as to achieve uniform vibration. The moving spacing is generally 300 400mm. When vibrating the upper layer, the lower layer 5 10cm should be inserted to make the two layers of concrete firmly combined.

When vibrating, the vibrating rod must not touch the steel bar and the formwork. 3. Pouring concrete should be carried out continuously. If it is necessary to intermittent, the intermittent time should be shortened as much as possible, and the secondary layer of concrete should be poured before the initial setting of the previous layer of concrete.

Generally, more than 2 hours should be treated according to the construction joint. 4. When pouring concrete, we should often observe whether the formwork, steel bars, reserved holes, and embedded parts have moved, deformed or blocked, and the problems should be dealt with immediately, and the concrete that has been poured should be corrected before the initial setting. (3) Beam, slab concrete pouring 1, beam, slab should be poured at the same time, pouring method should be used from one end"Pulp rushing method", that is, the beam is poured first, and the stepped shape is poured into a stepped shape according to the height of the beam, and then poured together with the concrete of the slab when the bottom position of the slab is reached, and the concrete pouring of the beam and slab is carried out continuously forward with the continuous extension of the stepped shape.

2. Beams with an overall height greater than lm are allowed to be poured separately, and the construction joints should be left at 2 3cm below the bottom of the slab. When pouring, pouring and vibrating must be closely matched, the first layer of material is slower, and the bottom of the beam is fully compacted and then the next two layers of material"Pulp rushing method"Keep the cement slurry along the bottom of the beam to wrap the stone forward, each layer should be compacted and then discharged, the bottom of the beam and the beam part should pay attention to the compaction, and the steel bar and embedded parts should not be touched when vibrating. 3. When the reinforcement of the beam and column nodes is dense, it is advisable to pour the concrete with small particle size stones of the same strength grade when pouring the concrete here, and vibrate with a small diameter vibrating rod.

4. The thickness of the concrete of the pouring slab should be slightly greater than the thickness of the plate, vibrate back and forth in the vertical pouring direction with a plate vibrator, and the thick plate can be vibrated with a plug-in vibrator along the pouring direction, and check the thickness of the concrete with an iron ruler, and smooth it with a long wooden trowel after the vibrating is completed. The construction joints or embedded parts and inserts are leveled with wooden trowels. When pouring slab concrete, it is not allowed to pave the concrete with vibrating rods.
