Wood or steel floor frames usually include a rim joist around the perimeter of a system of floor joists, and often include bridging material near the center of a span to prevent lateral buckling of the spanning members. In two-story construction, openings are left in the floor system for a stairwell, in which stair risers and treads are most ...
A flitch beam (or flitched beam) is a compound beam used in the construction of houses, decks, and other primarily wood-frame structures. Typically, the flitch beam is made up of a vertical steel plate sandwiched between two wood beams, the three layers being held together with bolts. In that common form it is sometimes referenced as a steel ...
Steel moment-resisting frames have been in use for more than one hundred years, dating to the earliest use of structural steel in building construction. Steel building construction with the frame carrying the vertical loads initiated with the Home Insurance Building in Chicago, a 10-story structure constructed in 1884 with a height of 138 ft ...
A table is built pretty much the same way as a beam formwork but the single parts of this system are connected together in a way that makes them transportable. The most common sheathing is plywood, but steel and fiberglass are used. The joists are either made from timber, engineered lumber (often in the form of I-beams), aluminium or steel. The ...
Frame joinery (e.g. face frames, web frames, door frames, table legs to aprons, chair legs) Cabinet carcase construction (e.g. carcase sides to top and bottom, fixed shelving/partitions) Panel assembly (for alignment) A variation of the dowel method for reinforcement is the use of a Miller dowel in place of the usual straight cylindrical dowel.
Steel frame structure Rectangular steel frame, or "perimeter frame" of the Willis building (at right) contrasted against the diagrid frame at 30 St Mary Axe (at center), in London. Steel frame is a building technique with a " skeleton frame" of vertical steel columns and horizontal I-beams , constructed in a rectangular grid to support the ...
Wood will expand and contract across the grain, and a wide panel made of solid wood could change width by a half of an inch, warping the door frame. By allowing the wood panel to float, it can expand and contract without damaging the door. A typical panel would be cut to allow 1/4" (5 mm) between itself and the bottom of the groove in the frame ...
