Precast Concrete Solid Walls
Solid walls can be made up to 12m, thus reducing the requirement of large supporting beams at floor level.
Up to 16mm diameter reinforcement can be catered for, walls are suitable for shear walls and within multi-storey buildings.
Advantages of Solid Walls
- Walls can be used as shear walls within a multi-storey building.
- Transfer or spanning walls can be made up to 12m, thus reducing the requirement of large supporting beams at floor level.
- All electrical socket outlets and conduits can be cast into both faces of the wall panel, conforming to BS standards and compatibility.
- Fully grouted connections at the end of the 200 think precast walls provide the required 50db sound rating.
- Steel RHS sections are cast into the solid walls to cater for the T25 vertical tie bars, (lapping of vertical ties within the RHS is not required as the cross sectional area of steel of the RHS is usually greater than that of the vertical dowel bars).
- Additional reinforcement can be cast into the wall panels at the production stage to achieve cantilever wall sections.
- Cast in items such as steel support angle, cono bar, or threaded sockets can easily be introduced during the manufacturing process, catering for on-site requirements.
- All door and window sizes can be catered for within the wall panel, additional reinforcement is automatically used to prevent cracking around opes.
- M16 sockets are precast into panel face to take diagonal push pull props on-site thus increasing installation speed and reducing damage to panel on-site.
- Steel wire loop (Phillips loop), connectors at the ends of the solid wall panels provide a fully grouted rigid connection with increased sheer capacity.
- Solid wall manufacture is based on an automatic production system, therefor overall lengths and prescribed reinforcement is always exact.
The Benefits of Precast Concrete Solid Walls
Concrete is a proven building material which has been used successfully for hundreds of years. Precast concrete’s versatility ensures that nowadays it is employed in a very wide variety of settings, from infrastructure, public buildings, and commercial projects to small residential properties.
Precast concrete has a number of advantages both during and after the building process. Because precast concrete walls can be produced in tightly-controlled conditions, quality and specification issues are addressed with accuracy and predictability. The fabrication process is not weather-dependent and the necessary skills are already on hand, along with expertise in design.
On-site, construction using precast panels is quicker and simpler. There is much less need for complex scaffolding and for the use of specialised skills. In volume projects, the use of modular precast components keeps costs down and speeds construction. Other trades, such as electricians, can be employed immediately after erection without waiting for the product to cure. Decorative finishes can be applied immediately, or can be incorporated in the fabrication process.
An attribute of precast concrete which is becoming increasingly important is its ability, relative to many other materials, to allow the transmission of wi-fi signals; this is nowadays seen as essential in the design of many commercial and educational projects, and has led to precast concrete becoming a first-choice material for schools and colleges.
Precast concrete is an energy-efficient building material, noted for its quality of ‘Thermal Mass’; concrete walls absorb the heat of the sun during the warmest part of the day, which they then release during the night. It is also fire-resistant and resistant to damage by vermin.
The aesthetic potential of precast concrete has been demonstrated by its use in some of the world’s most iconic structures, such as the Sydney Opera House; the soaring white “sails” so distinctive of this famous building are made of precast concrete and supported by precast concrete ribs. Adventurous architects have exploited the ability of concrete to be produced with a variety of finishes, from fine-grained and smooth to rough and patterned textures.
