The manufacturers requirements for the propping of lintel during construction must be followed, at all times. Masonry should be carefully built with solidly filled joints. Exposed faces of lintels must be provided with fire protection.
How much support does a lintel need?
Lintels generally require a nominal minimum end bearing of 150mm at both ends, meaning the total lintel length is the span of the opening plus 300mm.
Do I need a structural engineer for a lintel?
you do not initially need a structural engineer and the costs that this incurs. i always on every opening up to approx 5m span that is loadbearing use a service provided by catnic. you need to ensure that the wall is either loadbearing or not. a good builder or architect will assist quite cheaply to let you know.
How far back can building Regs be enforced?
How long is the application valid for? A Building Regulation application is valid for three years from the date of deposit. If you have started the works within the three years, there is no time limit to finish, however, the onus is on the owner to ensure regular visits to check progress are being requested.
Do you need building regs for RSJ?
Once your structural engineer has visited to assess the work, calculated the correct load and taken measurements for the beam (also known as an RSJ or joist and usually made of steel but can be timber), you will need to make a building regulations application to us and pay a fee before the work starts and provide us …
Do RSJ need to be fire boarded?
Please note you only need to achieve a specific standard of fire resistance, fire boards are not required, all plasterboard has fire resistance but you would need thicker/more boards.
Can a door frame act as a lintel?
If you keep the metal doorframe no need for a lintel as it acts as the lintel itself. If you remove the frame then you will need to install a lintel.

Lintels are generally used for load-bearing purposes, but they can also be decorative. The most common materials for lintels are timber, steel and concrete. Timber is low cost, readily available and can be easily cut to size on site. However, it is generally only suited to small openings with low loadings.
Can I use timber as a lintel?

What is a lintel?
A lintel is a beam placed across the openings like doors, windows etc. in buildings to support the load from the structure above. The width of lintel beam is equal to the width of wall, and the ends of it is built into the wall. Lintels are classified based on their material of construction. Horizontal lintels are easy…
When to use reinforced brick lintel?
Reinforced Brick Lintel These are used when loads are heavy and span is greater than 1m.
What is the minimum depth of a stone lintel?
The depth of this type is kept equal to 10 cm / meter of span, with a minimum value of 15 cm. They are used up to spans of 2 meters. In the structure is subjected to vibratory loads, cracks are formed in the stone lintel because of its weak tensile nature. Hence caution is needed.
