Building Walls Construction Quiz

Types of Roof Decks

• Plywood sheathing, Oriented Strand Board (OSB), and Wood Tongue and Groove are common types of roof decks in North America.
• Corrugated metal, Sprayable concrete encapsulated polystyrene, and Reinforced concrete are also used as roof decks.
• Double Tee Preformed Concrete is another type of roof deck.

Components of Roof Decks

• Sheathing, roof planks or slabs, and purlins are components of roof decks.
• In some cases, the roof deck serves as the roof support.
• In other cases, the roof covering and the deck are the same.

Concrete Roofs

• Cast-in-place and precast are two basic types of concrete roofs common in North America.
• Cast-in-place concrete is placed into forms at the building site and hardens in prepared forms.
• Precast concrete is placed into forms at a factory and transported to the building site.

Windows

• Hopper windows are hinged at the bottom and open inward.
• Jalousie windows include a large number of narrow overlapping glass sections swinging outward.
• Projecting windows swing outward at the top or bottom and slide upward or downward in grooves.
• Pivoting windows have a sash that pivots horizontally or vertically on a central axis.

Security Windows

• Windows may provide an access point for intruders, so security is frequently provided for windows.
• Metal bars or screens are often fastened to the exterior of the window frame or to the building itself.
• Security windows are available with movable sashes and fixed bars.

Rolling Steel Shutters

• Rolling steel shutters may be used to protect a fire wall opening in an industrial occupancy or an opening in a wall separating buildings into fire areas.
• Rolling steel shutters block interior window openings, such as office windows overlooking a factory floor.
• Rolling steel shutters have the same operating components as rolling steel doors.

Walls

• Walls define the perimeter of the building and divide it into compartments or rooms.
• Exterior walls may be wood or metal siding attached to studs, concrete blocks, or logs.
• Wall assemblies consist of a bottom plate, top plate, vertical studs, and horizontal braces sandwiched between two surfaces.

Fire Walls

• Fire walls provide separation to meet the requirements of a specified fire-resistance rating.
• Fire wall assemblies include the wall structure, doors, windows, and any other protected openings meeting the required protection-rating criteria.
• Fire walls may be used to separate two adjoining structures or two occupancy classifications within the same structure.

Doors

• Solid-core doors are better fire barriers than either panel doors or hollow-core doors.
• Hollow-core doors are less expensive and lighter than solid-core doors.
• Glass doors are used in both exterior and interior locations and are made of tempered glass that resists breakage.
• Metal doors, such as hollow metal doors, are made from steel or aluminum.
