Filler Joist Floor

Iron later steel joists embedded in concrete provided a crude form of reinforcing.

Filler joist floor. Filler joist as an early form of floor slab construction which was commonly used between about the 1880s and 1920s. Much more than documents. Of imposed loading per typical floor will be experienced by the existing structure following the change of use to hotel. According to the institution s librarians one of the most common requests they receive is for information on structural floor systems dating from the late 19th and early 20th centuries.

Abstractthe concrete filler joist floor was a form of fireproof flooring developed in the second half of the 19th century that came to be used quite extensively in industrial and commercial buildings. The reinforcement was usually embedded iron or steel joists although earlier examples can have wrought iron sections. 3 1 2 dead loads additional superimposed dead loads have been considered to allow for repairing and upgrading the existing concrete filler joists slabs to meet current regulation requirements e g. It was formed from iron or steel joists spaced up to about 1 m apart and in filled with unreinforced concrete.

A number of patented systems were developed at the end of the 1800s. The resource to the url or file is currently unavailable. Start free trial cancel anytime. The concrete filler joist floor was a form of fireproof flooring developed in the second half of the 19th century that came to be used quite extensively in industrial and commercial buildings.

Many structural engineers have for a long time been convinced that the effect of casing steel beams in concrete in the manner which has obtained for many years with the filler joist floor has a strengthening effect upon the floor and that it is safe to design the steelwork in such floors upon higher stresses than the extreme fibre stress of 7. They are installed tight to bottom flange with face mount hangers and tight to top flange with top mount hangers.
