The design of the structure dictates the necessity for a lintel. It’s a legal requirement that Building Regulation approval is necessary if the width of the existing aperture needs to be increased. The main thing to remember when looking to replace existing windows is that it’s essential to maintain the integrity of the building. It can be difficult to calculate the forces that the lintel will need to withstand, so it’s advisable to purchase it from a specialist merchant-bot who will be able to offer you some advice. Other important factors to contemplate are wall construction, the width of the opening and the weight of the load on the lintel. But, if in doubt, I’m advised it’s always far better to choose a lintel which is stronger than you need it to be, rather than opting for a potentially disastrous alternative. When deciding which type of lintel you’ll need for your particular opening, there are several things to take into consideration. Also, at the point where the lintel meets the supporting bricks, there will be a shearing force. The above load pushes down on the lintel and bends it, while the bottom is stretched under tension and the top is compressed. Tension and compression are the main forces that your chosen lintel must resist.
Which brings us to this week’s blog topic – lintels and the amount of force they have to resist. Starring R2-D2, C3PO and lots of other really cool droids (and also a few human-bots), Star Wars is the ultimate sci-fi fantasy saga featuring amazing spaceships, light sabres and the art of using the power of the ‘force’. We are getting ever closer to December and I just can’t wait to see the latest instalment of my absolute favourite film series – Star Wars: Episode VII – The Force Awakens. I’m so excited right now as I work tirelessly away in my testing lab. 24 November 2015 Posted in 2015 Mark II Lintels: Let the force be supported
