Anchor channels, invented by Anders Jordahl in 1913, are steel channels cast flush in reinforced concrete elements to allow the installation of channel bolts for the fastening of components. Anchor channels consist of steel C-shaped channels and anchors (mostly headed studs ) which are connected to the channel by welding or riveting/forging.
Anchor channels: used in precast concrete connections. [8] The channel can be a hot-rolled or a cold-formed steel shape in which a T-shape screw is placed in order to transfer the load to the base material. Headed stud: consist of a steel plate with headed studs welded on (see also threaded rod).
A pipe anchor is a rigid support that restricts movement in all three orthogonal directions and all three rotational directions, i.e. restricting al the 6 degrees of freedom This usually is a welded stanchion that is welded or bolted to steel or concrete. [2] In case of anchor which is bolted to concrete, a special type of bolt is required ...
An anchor plate, floor plate [1] or wall washer is a large plate or washer connected to a tie rod or bolt. Anchor plates are used on exterior walls of masonry buildings, for structural reinforcement against lateral bowing. Anchor plates are made of cast iron, sometimes wrought iron or steel, and are often made in a decorative style. [2]
A hold-down may also refer to clamping device used to anchor a pipe to a structural steel element or concrete floor or allow movement of the pipe in an axial direction. [1] At the bottom, the hold down is connected to the concrete foundation or structural slab by an embedded or epoxied anchor bolt. At the top, the hold down is connected to a ...
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1 ⁄ 2 to 1 + 1 ⁄ 2 inches (13 to 38 mm) in diameter.
Story – A post only one story tall as in "storeyed construction" [12] also known as platform framing. Prick – 1) Same as story post, a one-story post for extra support at a particular location; 2) In a roof truss a side post. [13] Ridge – A post extending from the ground or foundation to the ridge beam.
F/n = 23 kN per anchor during site lifting (n = 2 lifting anchors) Reference to the load capacity tables provided by the anchor manufacturer is required to make an anchor selection for the specific concrete strengths at the time of lifting. Hence the great of the two calculated anchor capacities required at the concrete strength of the initial ...
