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 ...
As such it may be understood as a subset of gridshell type roof constructions. The vault system comprises short structural members interwoven across a curved surface in a diamond pattern. [ 2 ] [ 3 ] Lamella structures can be constructed of wood timber or lumber, concrete, or metal. [ 4 ]
Other light-frame buildings are built over a crawlspace or a basement, with wood or steel joists used to span between foundation walls, usually constructed of poured concrete or concrete blocks. Engineered components are commonly used to form floor, ceiling and roof structures in place of solid wood.
A flitch beam is a simple form of composite construction sometimes used in North American light frame construction. [3] This occurs when a steel plate is sandwiched between two wood joists and bolted together. A flitch beam can typically support heavier loads over a longer span than an all-wood beam of the same cross section.
Cement bonded wood fiber materials can be classified as low density, medium density and high density. The density of the material will determine to a large extent, the various properties of the end product. Other factors determining the overall performance of a cement bonded wood fiber material are: Wood particle type; Wood particle gradation
A butterfly joint, also called a bow tie, dovetail key, Dutchman joint, or Nakashima joint, is a type of joint or inlay used to hold two or more pieces of wood together. These types of joints are mainly used for aesthetics, but they can also be used to reinforce cracks in pieces of wood, doors, picture frames, or drawers.
A hot roof is a roof designed not to have any ventilation and has enough air-impermeable insulation in contact with the sheathing to prevent condensation [11] such as when spray foam insulation is applied directly to the under-side or top-side of the roof deck or in some cathedral ceilings. [12]
A hammer-beam is a form of timber roof truss, allowing a hammerbeam roof to span greater than the length of any individual piece of timber.In place of a normal tie beam spanning the entire width of the roof, short beams – the hammer beams – are supported by curved braces from the wall, and hammer posts or arch-braces are built on top to support the rafters and typically a collar beam.
