Almost all buildings, like office buildings, schools, high rises, hospitals, shopping malls, and parking garages, are taking shape in cities. All of these structures look nicely clad in precast panels. These offer an array of styles, shapes, and colors.
Discussing the structural design aspects, the precast walls are like façade or blind dividers, which does not bear any load. These walls should oppose the parallel loads deliberated on it due to its weight, quakes, and winds. The joints in between the precast panels should be wider to match hot extension and variance developments because of the season changes. The divider and the hole space is guarded with a water-resistant film, this assures against water permeation into the construction.
There are three types of a precast concrete wall, take a look as we discuss briefly.
Curtain walls or cladding:
Curtain walls are popularly used for building envelopes. These do not carry any load and is technically designed to guard the wind and cover-up space. This kind of precast wall includes divider boards, section covers, spandrels, window divider units, and mullions.
Load bearing units exchange and oppose loads from various components, and it cannot be dismantled or removed without affecting the quality or reliability of the building.
Shear walls are used to offer a parallel load contrasting framework when linked with the stomach activity of a floor development.
The benefits of precast walling:
These panels are elegant and available in various finishes which include:
- Textured from liner
- Smooth as cast
- Exposed aggregate
- Acid etch
The strength keeps on increasing slowly with time. The exterior panels used for cladding can manage the structural construction loads, which reduced the requirement for structural components. These panels do not deflect over time, do not lose strength or deteriorate.
The durability of the precast walls is just like any other concrete, but the strength depends on the connections done with structural members. If there are any irregularities in the member, it can be corrected by uncovering, sandblasting, corrosive washing, and other methods.
These concrete products are manufactures inside a plant where the environment is controlled. This is mainly why the panels exhibit uniformity and superior quality.
Thermal resistance and energy savings:
These panels offer excellent thermal insulation, and due to this, you can also experience more energy savings. Precast panels have brilliant-value insulation properties. IT can also be increased with the help of embedded sandwich panels.
Protection from moisture:
This benefit of these panels is of higher importance because the structural components like beams and columns are not connected structurally with the precast walls. The joint seal or sealer is used in the joints to bock moisture from getting into the building. Generally, pigmented sealants are used to maintain the uniformity of these walls and the sealants.
Fire safety and maintenance:
These panels come with excellent fire-resistance, and concrete does not need any maintenance. The sealants, connection, accessories, and anchorages used in the precast walls require regular maintenance.
