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 ...
Animation depicting construction of multi-story building using aluminum handset formwork. Steel and plywood formwork for poured in place concrete foundation. 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]
In 1944 National Iron Works moved to its present location at 28th Street and Harbor Drive on San Diego Bay and in 1949 the company was renamed National Steel and Shipbuilding Co. to reflect the shipyard. [8] National Iron Works built some important San Diego structures, such as some of the plants in which Convair manufactured aircraft for World ...
In 1982 Marco sold the yard to San Diego Marine Industries, Inc. (not the well known San Diego Marine Construction, Inc.). San Diego Marine Industries, Inc. later became Southwest Marine in 1985. The shipyard closed in 1991 and was later sold, part of the land became the San Diego Convention Center. The shipyard was located at 1206 Marina Park ...
Slabs are one of the greatest consumers of concrete in many buildings, [14] so reducing the slab mass can make a relatively large difference to the environmental impact of a building's construction. Biaxial slabs may be marginally cheaper than solid slabs, partly due to the lower mass.
In situ: Formwork construction and pouring of concrete occur on site, then the slab is assembled (if required). [4] Precast: The slabs are made somewhere else and then brought to the site and assembled. [4] Pre-fabricated: The reinforcements are integrated into the slab while being manufactured, without needing to reinforce the assembly on site ...
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 ).
In 1981, the crane-independent formwork system for walls and slabs was marketed. In 1982, MEVA's Mammut wall formwork system was a heavy-duty system with a load capacity of 97 kN/m 2. In 1989, MEVA developed the aluminium wall formwork system. In 2000, MEVA created an all-plastic facing design. [3]
