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). [1] [2]
Shed roof attached to a barn. A shed roof, also known variously as a pent roof, lean-to roof, outshot, catslide, skillion roof (in Australia and New Zealand), and, rarely, a mono-pitched roof, [1] is a single-pitched roof surface. This is in contrast to a dual- or multiple-pitched roof.
Poles, from which these buildings get their name, are natural shaped or round wooden timbers 4 to 12 inches (100 to 300 mm) in diameter. [4] The structural frame of a pole building is made of tree trunks, utility poles, engineered lumber or chemically pressure-treated squared timbers which may be buried in the ground or anchored to a concrete slab.
Regular concrete is the lay term for concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other common material as the aggregate, and often mixed in improvised containers.
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 ...
The underside of a waffle slab, showing the grid like structure. A waffle slab or two-way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. [1] The name waffle comes from the grid pattern created by the reinforcing ribs.
The walls are erected by what is known as the drop-slab-panel system - upright panels formed of three-foot slabs cut from the outside slice of tree-trunks, and dropped horizontally, one above the other, between grooved posts - a simple arrangement, quickly run up and artistic in appearance - outside, a horizontally fluted surface, formed by the ...
An alternative is to put a strip of rubber underneath the floor slabs. Hollow-core slabs and wall elements without prestressed steel wire can be formed by extruders. The size of these elements will typically range in width from 600 to 2400 mm, in thickness from 150 to 500 mm, and can be delivered in lengths of up to 24 m. [1]
