Pre Cast Panel Detailing

Steel Structural detailing also provide pre caster panel detailing services. Precast cladding or curtain walls are the most common use of precast concrete for building envelopes. These types of precast concrete panels do not transfer vertical loads but simply enclose the space. They are only designed to resist wind, seismic forces generated by their own weight, and forces required to transfer the weight of the panel to the support. Common cladding units include wall panels, window wall units, spandrels, mullions, and column covers. These units can usually be removed individually if necessary.

There are generally four types of precast panels used as part of building envelopes:

1. Cladding or curtain walls
2. Load-bearing wall units
3. Shear walls
4. Formwork for cast-in-place concrete

Precast cladding or curtain walls are the most common use of precast concrete for building envelopes. These types of precast concrete panels do not transfer vertical loads but simply enclose the space. They are only designed to resist wind, seismic forces generated by their own weight, and forces required to transfer the weight of the panel to the support. Common cladding units include wall panels, window wall units, spandrels, mullions, and column covers. These units can usually be removed individually if necessary.

Load-bearing wall units resist and transfer loads from other elements and cannot be removed without affecting the strength or stability of the building. Typical load-bearing wall units include solid wall panels, and window wall and spandrel panels.

Precast concrete shear wall panels are used to provide lateral load resisting system when combined with diaphragm action of the floor construction. The effectiveness of precast shear walls is largely dependent upon the panel-to-panel connections.

In some cases, precast panels are used as formwork for cast-in-place concrete. The precast panels act as a form, providing the visible aesthetics of the system, while the cast-in-place portion provides the structural component of the system.

In most cases, the architect selects the cladding material for appearance, provides details for weatherproofing, and specifies performance criteria. The structural engineer designs the structure to hold the cladding, designates connection points, and evaluates the effects of structural movement on the cladding. The precast concrete manufacturer designs the cladding for the specified loads, erection loads, connection details, and provides for the weatherproofing, performance and durability of the cladding itself.

Precast concrete wall systems offer a wide variety of shapes, colors, textures, and finishes to the designer. As a result, the assessment of samples is a key component in the use of precast concrete. The majority of the review and approval process is conducted at the precast plant prior to precast panel production. This assessment is in addition to the quality control and field testing that takes place during the production phase.

Typically, each precast panel is independently supported to the building structure using an assemblage of metal components and anchors. Joints around each of the precast panels are usually filled with sealant.

Precast concrete refers to the concrete panels that are cast in a reusable mold or " form " which is then cured in a controlled factory environment. These concrete panels are then transported to the construction site and lifted into place. Precast concrete panels are the most commonly used building material in the world. Precast concrete opens up boundless possibilities to architects, designers, engineers, contractors, and all others involved in the building lifecycle.

Precast concrete panels come in all shapes & sizes, and forms. Some panels contain vertically and horizontally placed steel-reinforced concrete ribs, while others are just solid precast concrete panels. One of the main advantages of using precast concrete panels is that bad weather delays can be completely avoided as the concrete panels are cast in a controlled factory environment.

Steel Structural detailing has gained considerable expertise to provide you with the best and most feasible precast panel detailing services / precast panel shop drawings for all precast types.
