Structural Precast Concrete Wall Panels Details

Precast concrete wall systems are most often constructed as a curtain wall or veneer in which no building loads are transferred to the concrete panels.
Structural precast concrete wall panels details. Installable in just hours ag precast concrete wall panels are superior walls products that are specifically designed and modified for use above grade. In some cases precast panels are used as formwork for cast in place concrete. With proper structural considerations multiple precast panels can be connected to achieve multi story construction. Precast concrete shear wall panels provide a lateral load resisting system when combined with the diaphragm action of the floor construction.
Insulation is full width and height. They offer design flexibility time savings and improved profitability too. Thin shell wall panels consist of a thin outer wythe of concrete typically ranging between 1 5 and 3 inches in thickness. Precast concrete offers the aesthetics affordability durability strength and speed of installation owners and architects want in a building material.
The insulation thickness can vary to create the desired thermal insulating property r value for the wall. Every precast wall panel has a thick layer of energy efficient thermal insulation integrally sandwiched between a very durable concrete interior and a unique beautiful exterior finish. As well as vertical loads resulting from the self weight of the precast wall system. Insulated structural wall panel the difference between standard wall panels and insulated wall panels is that the latter are cast with rigid insulation between two layers or wythes of concrete.
The effectiveness of precast concrete shear walls is largely dependent on the panel to panel connections. Along with lowering heating and cooling costs this helps to meet stricter energy requirements. These loads must be transmitted through the wall system and secondary structural elements to the building s structure. But precast concrete building envelopes don t stop there.
Precast concrete wall panels and veneer are typically lightweight and easy to install with products ranging from thin brick veneer to cladding inspired by limestone travertine and other stone products. Most typically the precast concrete wall system must resist lateral loads directly imparted on it such as from wind and earthquake. The use of precast concrete reduces the heat island effect and provides thermal mass which delays heat transfer through building walls and moderates indoor temperature fluctuations as outdoor temperature varies. This combination is also completely fire resistant and sound transmission is reduced allowing intrusive noise to be kept at a minimum.
