Riser clamp for a standpipe through-penetration firestop inside a fire hose cabinet under construction. A riser clamp is a type of hardware used by mechanical building trades for pipe support in vertical runs of piping (risers) at each floor level. The devices are placed around the pipe, and integral fasteners are then tightened to clamp them ...
A hold-down may also refer to clamping device used to anchor a pipe to a structural steel element or concrete floor or allow movement of the pipe in an axial direction. [1] At the bottom, the hold down is connected to the concrete foundation or structural slab by an embedded or epoxied anchor bolt. At the top, the hold down is connected to a ...
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
A concrete frame, also known as a concrete skeleton, is a structure composed of interconnected beams, columns, and slabs that is used to support larger structures. [ 1 ] [ 2 ] Due to the low cost of producing them, concrete frames are often used when building damns, bridges, and buildings.
Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]
The function of rebar spacers is to maintain the precise positioning of steel reinforcement, facilitating the implementation of theoretical design specifications in concrete construction. This includes ensuring the appropriate steel cover for specific structural elements (such as in a concrete slab or a beam ) should be generally uniform within ...
construction site workers loading water, sand, ballast and cement into a concrete mixer. Concrete is typically used in commercial buildings and civil engineering projects, for its strength and durability. Concrete is a mix of cement and water plus an aggregate such as sand or stone. Its compression strength means it can support heavy weights. [5]
