Suspended Beam & Block Floor PREPARATION
When using Supreme T Beams, you are considerably reducing site preparation, only needing to ensure that the ground beneath the floor is cleared of top soil and vegetation. No oversite concreting is required. VENTILATION
Provision should be made for a void beneath the floor the depth of which should be at least 150mm but may vary depending on site conditions. To meet local authority and NHBC requirements, the void beneath the floor should be ventilated. Ventilation openings should be placed to enable the free flow of air to the complete under floor area. Ventilators should be placed frequently enough to the perimeter of the building to give suitable ventilation. Supreme supply plastic telescopic void ventilators with a range of coloured plastic air bricks. INSTALLATION
It is essential that the floor beams be handled and stacked the correct way up, they should be lifted as close to the ends as possible and no damaged beams should be used in the installation. It is important that all mortar in the preceding work is adequately cured, having enough strength to give support to the floor being installed. Ensure that all mortar and debris is removed from the bearing points and they are level and true. Generally a DPC should be placed over all bearings before laying a ground floor. Beams should have a nominal bearing of 100mm on masonry. Please adhere to starting beams on our working drawings and set beams out bay by bay. Take note of critical partition walls etc. Take care to make sure all beams are parallel and that there is a nominal 18mm bearing for the block (hard packing can be used for this purpose if necessary). Ensure layout is as our working drawing before placing all infill and closure blocks. Note! Closure blocks should not be used to space the beams; they should be installed using mortar when all blocking out is complete. The floor should be completed as soon as possible by brushing in a wet grout mix of 1:3 cement and sharp washed sand, a stiffer mix of the same proportions should be used to fill any double or multiple beams, these joints should be "hard packed". The floor should be cleaned and wetted prior to grouting, to enable grout to penetrate providing a firm construction. Prestressed floor beams have an upward camber. The camber in standard units will be within the limits of BS8110 and should not exceed L/300. The camber should be considered especially on larger spans and / or when non-screed finishes are specified. A levelling screed could be incorporated. DOMESTIC GARAGE USE
When a beam and block floor is used in a domestic garage or similar application where high concentrated loads are evident a reinforced screed must be applied directly to the top of the beams and blocks. The screed should have a compressive strength of 21N/mm2 with light steel mesh reinforcement. Such as an A98 steel mesh. BEAM PROPERTIES AND STRUCTURAL CALCULATIONS
Where the design layout drawings have been produced by Supreme then full structural calculations can be provided upon request. BENEFITS
Fast installation with no specialist
skills needed.
On site cost benefits with most costs known beforehand.
Less preparation, no hardcore or over-site concreting worries, can reduce internal foundations. After grouting you have an immediate working platform.
Can eliminate some delays due to inclement weather. The T-profile allows easier handling, placement and storage of the product
on site. Rotproof, draughtproof, fire resistant, improved insulation. Suitable for many applications from housing & flats to schools & offices. Capable of sustaining some non-loadbearing block partitions.
