Precast concrete walls are constructed by casting concrete in a reusable wall mold or form which is then cured in a controlled environment, transported to the construction site and lifted into place. The main function of the precast walls is to speed up the construction process.
It is common that the structural engineer shows the internal forces and connection locations, and the manufacturer’s engineering department provides the final design and details of the connections. This paper describes basic types of connections and joints used in precast concrete structures.
Precast Insulated Wall Panels (PIWPs) have been used in building construction for over five decades1. A PIWP consists of a layer of insulating material “sandwiched” between two wythes of concrete.
Architectural precast concrete has been used since the early 20th century, coming into wide use in the 1960s. The versatility of precast concrete makes it ideal for architectural applications. The exterior surface of a precast concrete piece can vary from a form face finish similar to cast-in-place to an exposed aggregate
25 lip 2023 · Based on the literature review carried out, it is possible to identified three different types of prefabricated walls, according to the type of cross-section : (a) simple/plain walls; (b) insulated/sandwich walls; and (c) double/composite wall.
The following sections from the PCI Design Handbook include interaction curves, load tables, and section properties for various precast concrete components. You can access tables from previous editions of the handbook as well as the current edition.
Precast concrete walls, made up of prefabricated concrete panels, are a popular choice for modern construction. The precast wall installation process involves first preparing the construction site and foundations, then lifting the precast wall panels into place with a crane and connecting them.
