CAST-IN PLATE WITH DETAILS

A steel plate which is casted in to concrete for connection purpose is named cast-in-plate. Connections may be required to carry shear and axial force between the precast elements for applied load conditions.

Cast-in plates are used to tie/ fix,

1. Concrete or precast panels to each other.
2. Precast to insitu slab.
3. Steel beams to the Precast panels/slabs.

All purpose of connection except steel beam to precast connections required pair of cast in plate connected by a welded plate . But the steel beam to precast connection required only a cast-in plate with cleat plate is enough . All the plates and connections details are need to approved by Structural Engineer.

1 Panel to Panel connection:

Normally the lift shaft panels & stair panels have to connect withstand maximum shear and axial loads. The vertical panel joints are made by the cast-in plate connection. Minimum two no of connections per level is needed (need to get structural engineer advise).

The cast in plate casted with pocket to cover on later stage. Both perpendicular & in line panels are also can be able to connect. We can able to connect insitu wall to precast panel also by this method. Refer blow picture for better understanding.

2. Precast to Insitu slab Connection:

For Particular requirement the precast should be connected with slab. One cast in plate casted in to the slab and another one is casted in to the precast and both the plates are connected through weld plate by weld on site. Refer below picture for better understanding.

3. Steel beams to the Precast Connection:

Now a days the construction system are versatile various types of constructions systems are used to complete the same building. Steel building with precast walls are also preferred as a one type of construction system.

Where the steel beams are meet the precast panels the cast-in plate is used to connect it. Here instead of weld plate cleat plate is used to connect between the steel member to precast wall. The cast in plate on the precast walls not cast with the pocket it is flush with surface.
