AAC is well suited for high-rise buildings and those with high temperature variations. [24] Due to its lower density, high-rise buildings constructed using AAC require less steel and concrete for structural members. The mortar needed for laying AAC blocks is reduced due to the lower number of joints.
The anchor selection, together with additional reinforcement, and rigging arrangements is influenced by: - The dead weight of the element - The number of anchors in the element and the configuration of the anchor - Capacity of the anchor at the specific concrete compressive strengths at time of lift - The dynamic loads applied during lifting ...
Anchor bolts are used to connect structural and non-structural elements to concrete. [2] The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners.
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.
Pipe expansion joints are necessary in systems that convey high temperature substances such as steam or exhaust gases, or to absorb movement and vibration. A typical joint is a bellows of metal (most commonly stainless steel ), plastic (such as PTFE ), fabric (such as glass fibre) or an elastomer such as rubber .
