Concrete reinforcing is custom-fabricated from 60-foot-long reinforcing bars. [5] The reinforcing bars are cut to length and bent to specific configurations. The shop drawing and the accompanying “cut sheet” lists the quantity, sizes, lengths, and shapes of the reinforcing bar. [5]
A pallet of "8-inch" concrete blocks An interior wall of painted concrete blocks Concrete masonry blocks A building constructed with concrete masonry blocks. A concrete block, also known as a cinder block in North American English, breeze block in British English, or concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.
Plastic spacers and bar supports do not bond well with concrete and are not compatible materials. [1] Plastic has mechanical properties (holds the bar in position) but no structural properties, and is a foreign element within the construction. When the concrete is poured into the form, a small gap is created between the concrete and the plastic.
D500N12 is deformed bar, 500 MPa strength, normal ductility and 12 mm nominal diameter – also known as "N12" Bars are typically abbreviated to simply 'N' (hot-rolled deformed bar), 'R' (hot-rolled round bar), 'RW' (cold-drawn ribbed wire) or 'W' (cold-drawn round wire), as the yield strength and ductility class can be implied from the shape.
The starter bar is constructed in discrete blocks secured to one side of a planar spine provided in segments and arranged end to end. Adjustable spacers in the form of tapered blocks are disposed between the blocks of the bar to allow the starter bar to be self-supporting in a curved configuration corresponding to the casting path.
A crash bar (also known as a panic exit device, panic bar, or bump bar) [1] [2] is a type of door opening mechanism which allows users to open a door by pushing a bar. While originally conceived as a way to prevent crowd crushing in an emergency, crash bars are now used as the primary door opening mechanism in many commercial buildings.
A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle. Tie rods and anchor plates in the ruins of Coventry Cathedral
Door chains — allows the doors to be opened slightly to view outside while still remaining locked. Secondary, internal locks — sliding bolts, hooks and speciality latches, metal blocks or bars mounted internally. Hinge screws — longer or specialized screws that prevent the door from being simply pulled out after removing the hinge pins.
