AS 3850.1:2015 pdf free.Prefabricated concrete elements Part 1: General requirements.
1.4.20 Erection designer
A competent person who is an engineer and is responsible for the erection design of the structure.
1.4.21 Erection platform (crane standing)
The base that supports the crane during erection of the prefabricated concrete elements.
1.4.22 Expansion anchors
Anchors placed in appropriately sized holes drilled in hardened concrete, which rely on expansion devices interacting with the sides of the hole to prevent pull-out under design load. The two types of expansion anchors are the following:
(a) Deformaiion-conrrolled—anchors that are expanded only during installation. NOTE: Application of load to the anchor does not increase the expansion forces.
(h) Torqzw-onfrolleci l’also rcferred Ia as laad-conlrollcdi——anchors that have a wedge and expansion-shield system where the wedge is directly connected to the applied load.
NOTE: Increases in load above the retained preload (obtained from initial torque) will increase the expansion force.
1.4.23 Face-lifting
A method of lifting a prefabricated concrete element using lifting inserts located in the as cast’ upper surface of the element.
NOTE: See Figure 2.4 of AS 3850.2.
1.4.24 Ferrule
A cast-in insert to accept a threaded bolt.
1.4.25 Fixing insert
A component or system cast or post-installed into the prefabricated concrete element and subsequently used to bolt the structure together or support other architectural or structural members.
1.4.26 Flat-lifting
A method of lifting a prefabricated concrete element where the orientation of the element does not change throughout the lift.
NOTE: Sec Figure 2.2 of AS 3850.2.
1.4.27 headed insert
A type of insert with an enlarged cast-in end that is installed before placing concrete, which transfers load to the concrete by way of mechanical interlock at the insert head.
1.4.28 Innovative insert
Any insert that does not conform to the requirements of a reference insert.
1.4.29 Insert spacing
Distance between the centre-lines of the inserts.
1.4.30 In-servIce designer
A competent person who is an engineer and is responsible for design of the structure or element to resist the load the building will experience in its lifetime subsequent to completion of construction.
NOTE: The in-service engineer ensures that the design is constructible.AS 3850.1 pdf download.
