A.I.4.2: CONCRETE EXECUTION METHODS FOR BODY PART

RAW MASONARY

Execution of wall, concrete, steel, pit floor

Base on structure thiết kế contractor estimate, design using casing and recycling during work.

Reinforcement assembling

Tie bloông xã concrete with the same thickness as protected concrete và grade as one of structure concrete.

Preliminary acceptance for reinforcement

Drill concrete floor to hammer steel khổng lồ fix wall thickness

Formwork assembling in one side only

Pour concrete for wall

Reinforcement assembling

Before install steel for the wall, contractor uses survey machine lớn define centre of pivots on the concrete floor

Base on pointed centre on the concrete, check the right position of steel, tight steel to lớn other steel in case of right position

* Wall reinforcement procedure

– Drill to create roughness of wall foot concrete và clean

Pit floor wall concrete stamping method

Before pouring concrete wall, contractor uses pump lớn water wall foot brichồng & pour a cement layer with rate ½ và phối additive sầu for damp-proof. After pouring mortar, pouring concrete immediately.

Wall concrete has 14cm- landslide, distance between wall steel is large. Thus, contractor uses stamping machine with diameter D50, radius is equal as 1/3 as length of power hammer. When covering next layer on previous layer, power hammer is staked out with the depth of more than 5cm.

Concrete pour requirements

Avoid changing position of steel, formwork and guarantee the depth of protected concrete layer.

Pouring concrete continuously in oder to lớn avoid separately of concrete until finishing any structure following khổng lồ thiết kế.

The height of falling concrete is smaller than 1.5m to lớn avoid classifying. If it is higher than 1.5m, pour concrete by sloping conduit or movable pipe. Material conduit must be smooth & hermetic. Material conduit width is as 3.5 times as the largest diameter of reinforcement. Slope of conduit is guaranteed for concrete not stuông xã.

Pouring concrete note:

Formwork, scaffold & reinforcement are tested tightly in case of trouble.

Concrete is stamped by stamping machine. All position is stamped in the right way.

Canvas is available to cover concrete when rain. Concrete is not poured because of problems, wait until it reaches at 25kg/cmét vuông. Before pouring, roughness flat is handled, pour solid cement, mix additive for damp-proof.

Thickness of concrete layer bases on concrete supply, transport distance, type of stamping power, characteristic of structure & it doesn’t exceed standards:

Straight stamping: Length of each layer Reinforcement concrete column execution methodCasing, reinforcement

Reinforcement column belong khổng lồ system that burden all loading capađô thị of work, thus, contractor concern about seriously

Base on kích thước of each structure, contractor uses casing of contractor as formwork column.
