2. Precast concrete lifting anchor system - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete_lifting...

   F = W x Ksl x Ks x 0.5 = 64.8 x 1.16 x 1.2 x 0.5 = 45.1 kN; Anchor capacity for initial lift F/n = 23 kN per anchor during initial lift (n = 2 lifting anchors) Transport loads in the yard and on-site Suction due to casting bed adhesion is not considered, as the calculation takes into account the lifting device dynamic coefficient.

   This 5 ⁄ 16 inch (7.9 mm) thick cement board is designed as an underlayment for tile floors. These are 3-by-5-foot (91 by 152 cm) sheets. These are 3-by-5-foot (91 by 152 cm) sheets. A cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. [ 1 ]

5. Anchorage in reinforced concrete - Wikipedia

   en.wikipedia.org/wiki/Anchorage_in_Reinforced...

   Conventionally the term concrete refers only to concrete that is reinforced with iron or steel. However, other materials are often used to reinforce concrete e.g. organic and inorganic fibres, composites in different forms. While compared to its compressive strength, concrete is weak in tension. Thus adding reinforcement increases the strength ...

6. Anchor bolt - Wikipedia

   en.wikipedia.org/wiki/Anchor_bolt

   Column-to-foundation connection [1] 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 bolts transfer different types of load: tension forces and shear forces. [3]

7. Anchor plate - Wikipedia

   en.wikipedia.org/wiki/Anchor_plate

   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]
