Concrete continues to be the preferred method for capping vertical shafts. Considerations can be made in the design to allow for an entrance to the mine, a steel door for humans, a slot for bats, a hole for airflow. The slab thickness can vary from as little as 6 inches to several feet.
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 ...
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]
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 ...
British Railways shed codes were used to identify the engine sheds that its locomotives and multiple units were allocated to for maintenance purposes. The former London, Midland and Scottish Railway (LMS) alpha-numeric system was extended to cover all regions and used until replaced by alphabetic codes in 1973.
Compared to traditional solid slabs, the reduced self-weight of biaxial slabs allows for longer spans and/or reduced deck thickness. The overall mass of concrete can be reduced by 35–50% depending on the design, [ 1 ] as a consequence of reduced slab mass, as well as lower requirements for vertical structure and foundations.
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.
Hopkins and Riley followed up that book with Inventions from the Shed (1999) [17] and a 5-part film documentary series with the same name. [18] Gordon Thorburn also examined the shed proclivity in his book Men and Sheds (2002), [19] as did Gareth Jones in Shed Men (2004). [20] Recently, "Men's Sheds" have become common in Australia. [21]
