A reinforced concrete frame is a load-bearing skeletal or framing structure composed of concrete which is poured wet on the site then dried during construction, using steel reinforcing bars (rebar) to add tensile strength. Buildings of this type have structural systems consisting of a framework of reinforced concrete columns, beams, and girders. It is a very common framework material for medium and large structures. Concrete is a hard aggregate substance made from cement, lime, crushed rock or sand, water, and other ingredients.
Concrete performs exceptionally well under compression but not well under tension, so almost all concrete used in...
The Hambro® Floor System combines composite joists with poured concrete, developing a hybrid concrete / steel T-beam running in one direction and an integrated, continuous slab in the opposite direction. The system utilizes reusable Rollbars® and plywood forms
The concrete slab is reinforced with welded wire mesh at the required locations and behaves structurally as a continuous one-way reinforced concrete slab.
The rigid plywood sheets and Rollbars, when locked into the top chord section, not only act as simple forms for placing concrete, but provide the essential lateral and torsional stability to...
Refers to a building technique with a "skeleton (http://en.wikipedia.org/wiki/Skeleton) frame" of vertical steel columns and horizontal I-beams , constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper (http://en.wikipedia.org/wiki/Skyscraper) possible. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated mold, these "forms or molds are then filled with reinforcing and concrete to create structural floors within the frame. Regarding our scope of work for these types of buildings, in addition to the floors(including the slab on grade), we supply the reinforced cast in place foundation systems that support the skeleton frame.
Tilt-up construction requires significant organization and collaboration on the building site. The chronological steps that need to be taken for a tilt-up project are: site evaluation, engineering, footings and floor slabs, forming tilt-up panels, steel placement, embeds and inserts, concrete placement, panel erection and panel finishing. Once the pad (casting surface or floor slab) has cured, forms (http://en.wikipedia.org/wiki/Forms) are built on top. Dimensional lumber, a high quality plywood or fiber board that has at least one smooth face is typically used, although aluminum or steel forms are also common. Carpenters (
