Sharp and Strong don’t just supply steel framed buildings, we build them for our clients as well. Building your steel framed building requires careful planning.
Erecting a steel building has to take into account positioning, alignment and ensuring that all the components are secured on prepared foundations to form a completed frame.
Erecting a Steel building has four main areas of consideration:
- Foundations need to be suitable and safe.
- Lifting and placing of all the components into position. Will we use cranes or jacking? To secure components in place bolted connections will be made, but will not yet be fully tightened. Bracings may similarly not be fully secured.
- Alignment of the structure by checking that column bases are lined and level and columns are plumb. Packing in beam-to-column connections may need to be changed to allow column plumb to be adjusted.
- Bolting-up. This means completing all the bolted connections to secure and impart rigidity to the frame
Therefore, through careful planning we’re able to take advantage of the speed offered by using a steel construction.
Three main planning factors that could affect the building of your steel frame building are:
1. Practical erection sequence to maintain structural equilibrium.
2. Simplicity of assembly.
3. Logical trade sequences.
Site work can be labour intensive and quite expensive. Our aim is be to reduce costs by shortening the time on site.
The principal design factors affecting the erection of steel buildings are:
- Repetition and standardization. Two aspects to standardization are:
- repetition of the same building type
- common/standard details for connections
- Achievable tolerances. If ‘tight’ tolerances are specified too tight, then special controls will be needed and possibly specially-engineered details.
- Frame type. Here, the primary choice is between simple and rigid-jointed frames, the former being much quicker and easier to erect.
- Floor systems. For multi-story frames, the choice of floor system will affect the erection sequence as it determines the stability of the part erected structure, and how quickly other trades can follow-on.
“Erecting a steel building on site means that we’ll be putting all the components of the building in place and then connecting them.”
Site Safety is very important to us.
Site safety is an essential part when erecting steel framework structures. Which can be vulnerable to collapse, cranes can overturn or drop large components, and work on the frame requires erectors to be at heights from which a fall could well be fatal. Regulations lay down mandatory requirements regarding the provision of equipment and arrangements to minimise the risk of an accident.
Structural stability must be preserved at all stages.
Preservation of the stability of the structure is vital as structures that do collapse do so during erection. These failures can often arise due to simple communication issues i.e. lack of communication on the site.
