Gallows VS Beam to Support Chimney
KUN ARCH INSIGHT: CHOOSING BETWEEN GALLOWS AND STEEL BEAM FOR CHIMNEY SUPPORT
In the UK, opting for gallows brackets presents a cost-effective approach to support the removal of a chimney breast. However, it’s crucial to note that several Borough councils express reservations about this method due to potential issues with adjoining neighbours who might wish to remove their chimneys in the future. Delve into the pros and cons outlined below to make an informed choice between gallows brackets and the more conventional steel beam method.
KUN ARCH PERSPECTIVE: ADVANTAGES OF GALLOW BRACKETS FOR CHIMNEY SUPPORT
KUN ARCH PERSPECTIVE: ADVANTAGES OF GALLOW BRACKETS FOR CHIMNEY SUPPORTIn the United Kingdom, Gallows Brackets offer certain advantages in supporting the removal of a chimney breast. However, it’s essential to consider potential challenges, especially concerning future decisions by adjoining neighbours. The brackets, crafted from mild steel angle brackets, are intricately cut and welded to form a support structure beneath the targeted chimney breast. This bracket is then securely fastened using resin anchors into the Party Wall. However, local Building Control authorities often express reservations about this approach due to its impact on the Party Wall and the potential implications for neighbouring properties. Below are the key points to consider when contemplating the use of Gallows Brackets for chimney support:
- Structural Details: Gallows Brackets consist of mild steel angle brackets that are meticulously cut and welded, providing support beneath the chimney breast slated for removal.
- Fixing Process: The brackets are drilled and bolted with resin anchors into the Party Wall. It's crucial to note that this particular section of the wall is thinner due to the presence of brickwork flues.
- Adjoining Neighbour Considerations: One of the primary concerns arises if the adjoining neighbour decides to remove their chimney at a later date. In such instances, the bolts and brackets may pose challenges for future modifications, potentially weakening the shared wall.
- Suitability for Singular Use: Gallows Brackets are most suitable when only one party intends to utilise this method. If both parties plan to adopt this approach, issues may arise, as the bolts from multiple brackets could interfere with each other and compromise the structural integrity of the wall.
- Timing and Agreement: The decision to use Gallows Brackets should ideally be a collaborative one, ensuring that both parties involved are in agreement about the chosen method. It operates on a "first-come, first-serve" principle, where the first party to decide to keep the chimney can use the bracket.
KUN ARCH PERSPECTIVE: CONSIDERATIONS OF UTILISING STEEL BEAMS FOR CHIMNEY SUPPORT
In the realm of construction in
the UK, opting for Steel Beams to facilitate the removal of a chimney involves several considerations. It is crucial to understand the context of your neighbour’s chimney status and abide by local council policies, which prioritize extra safety measures. The use of Steel Beams is seen as a strategic choice that circumvents reliance on the party wall, offering a secure alternative with potential long-term benefits. However, this approach comes with its own set of aspects to ponder:
- Neighbour's Chimney Status: Before choosing Steel Beams, it's imperative to ascertain the status of your neighbour's chimney – whether it has been removed or not. Local councils often favour options that prioritise the avoidance of the party wall entirely.
- Council's Safety Policy: Local authorities often view the deployment of Steel Beams as a safer alternative, steering clear of potential complications associated with party wall interventions.
- Avoidance of Future Issues: Opting for Steel Beams allows both neighbours the flexibility to remove their chimneys independently without the need for constant communication. This avoids the need to coordinate and inquire about the actions of the neighbouring property.
- Cost Considerations: While effective, choosing Steel Beams may come at a higher cost compared to alternatives like gallows brackets. The approximate cost for a 3-meter length of steel beam can be around £200+vat, adding to the overall project expenses.
- Party Wall Surveyor Involvement: Fixing Gallows Brackets to the party wall may necessitate the involvement of a party wall surveyor, incurring additional expenses. Opting for Steel Beams could potentially eliminate the need for such intervention, providing a more cost-effective solution.
Understanding the intricacies of utilising Steel Beams for chimney support is crucial for making informed decisions aligned with both safety protocols and financial considerations in the construction process.
