G4 - Construct Suspended Slabs Flashcards
In what sequence does form stripping usually take place?
Beam sides, then the slab soffits.
Top down and outside inward.
What is the first step in setting a beam form?
Placing beam bottoms on top of the shore system.
What must be done to the forms for deep girders?
Studs are added to the sides.
Why does a spandrel beam require a wider shorehead than other beams or girders of the same width?
Studs are added to the sides.
Why does a spandrel beam require a wider shore head than other beams or girders of the same width?
To provide space for a work platform.
Where do beam sides usually sit?
On the shore head.
How are wooden T-shores set to elevation?
Wedging
How are forms for drop panels supported?
Shores, stringers and joists.
Basic beam support starts with:
T-Shore or double post shore (bent) placed on the floor.
Beam bottoms should be set to elevation, this is done by leaving all shore posts how short?
1 “ to 1 1/2” Inch
Always chalk lines where?
On concrete, not form or plate
Beam sides:
Once beam bottoms have been attached and leveled, beam sides can be assembled and installed.
Deeper beams require stronger beam sides and require?
Stronger beam sides, and adding support to plywood are unnecessary. Units built on the floor using bottom plates and studs attach the plywood and then are passed up to the working platform.
Spandrel Beam
Outside edge of slab, act to strengthen the slab at the perimeter.
How can you strengthen and keep top of slab straight?
Special tie called spandrel or deck ties are used with walers to accommodate this.
