Many of these installations continue to perform and provide support to.
Lightweight precast concrete planks.
Roof and floor deck systems.
Gypsum deck plank for roof decks.
Place plank on lower flanges of sub purlins or other framing with ends and edges supported.
If the deck is sound it may be possible to treat the deck much like concrete by priming the surface adhering thermal insulation and installing a new roof membrane.
Structural wood fiber decking a grey area between combustible and noncombustible decking is the structural wood fiber deck system.
Structural panel concrete roof deck is versatile and economic option for both low and steep slope roofs.
For fire rated roof decks weld per fire test assembly.
Use minimum 13 mm 1 2 inch fillet welds on alternate sides of sub purlins both sides at end joints to main purlins.
Formboards placed between the bulb tees contain the fast.
Gypsum or lightweight concrete deck.
The roof deck consists of a flat deck of 3 solid gypsum planks 1 wide and 3 long supported by doubled light gage channels in turn supported by structural steel framing.

Gypsum concrete roof deck systems have been installed since the early 1950 s in all types of commercial markets.
Gypsum or lightweight concrete deck.
These fibrous decks generally have a gypsum like or cementitious binder and combine the functions of a roof deck thermal insulation and finished ceiling.
These include office complexes schools public buildings shopping malls and warehouses located throughout the united states.
Unlike traditional roofing systems where multiple layers are required concrete roof deck is both the noncombustible structural sheathing and either the nail base or thermal barrier.
Collaboration with the structural engineer.
The planks are not poured on site but precast.
Gypsum concrete roof deck systems consist of a form board wire reinforcement and a poured application of gypsum concrete.
This system provides fire resistance seismic and wind load diaphragm values in addition to an economical roofing membrane substrate.
The gypsum roof deck system is supported by bulb tees generally spaced from 24 to 32 on center.
Introduced as a roof deck substrate in the 1940 s.
Examples of gypsum roof decks.
Old bald asphalt roof over wet fiberboard over asphalt felts and the white.
Because a roof deck is the foundation for the roof system the designer needs to coordinate the roof system design requirements for the roof deck with the structural engineer to ensure the performance of the roof system.
