Steel structure slab concrete construction plan(4)
The main construction process: measuring the release line → installation of steel plate template around the floor → short beam welding on the steel beam → steel banding → reserved hole template installation → floor concrete pouring
main construction methods
Order of concrete pouring
Starting from the farthest point and the periphery of each unit, from the farthest to the nearest place, the concrete is poured at one time.
Vibration of concrete
Before the concrete is poured, the vibration machinery and the electric box are all inspected again. After the completion of the concrete inspection, the person in charge of the technical approval is approved before the concrete can be poured. Personnel and machinery must be prepared adequately. The flat vibrator is used, and a special person is responsible for guarding against leakage vibration. At the same time, when pouring the flat plate, pay attention to the concrete pile material should not be concentrated too much, prevent the pile material from being too concentrated, and the template load is overweight, causing quality accidents and dangers.
Pre-control of construction quality of concrete construction
Concrete construction safety measures
When pouring concrete, the height of the surrounding protective railing should be at 1.1 meters.
When concretework is used for concrete pouring, it should be equipped with a seat belt and suspended in a firm position for construction.
When constructing at night, the pouring site should be equipped with sufficient lighting facilities.
