Block And Beam Sizes

Beam and block load span tables. They have been designed to be highly practical for ground and upper floors quick and easy installation in all weather conditions without the need of specialist skills.

The load span chart below clearly shows the maximum span for the required loading using either aerated medium or high density infill blocks and 65mm screed.

Block and beam sizes. Grout infill between 30 deep x 120 long Standard block 36Nmm or block strength to suit wall by the Builder. In order to prevent damage to beams they should be stacked on battens on a hard level surface. The beams vary in depth and can be 130mm to 250mm made up to lengths of around 6m they are usually designed and manufactured to span specific distances.

Nominal dimensions refer to the module size for planning bond patterns and modular layout with respect to door and window. CBCut Block CB Insitu concrete around pipe by the Builder. 406 mm available in nominal thicknesses of 4 6 8 10 12 14 and 16 in.

Sometimes where the floor spans over a long distance more sleeper walls or intermediate support is required. There are three beam types which are produced in standard profiles of 150 x 125mm 150 x 215mm and 225 x 135mm depth x width to give a range of capacities to suit all loading options. 15 20 25 30 40 50 Beam Maximum Clear Span m TJ3 298 775 775 745 720 680 640 Ref Self weight kNm2 Imposed load in kNm2 15 20 25 30 40 50 150mm Beam Maximum Clear Span m RDJ6 247 645 625 605 580 545 515 The floor self weight includes the weight of the beams and the concrete blocks.

Our concrete t-beams are available in 155mm and 225mm deep pre-stressed options in lengths of 1-6m in 50mm increments. 150mm concrete beams are most commonly used in domestic house building projects garages extensions conservatories etc. The approximate self weights of beams are.

102 152 203 254 305 356 and 406 mm. Cantilever beam Typically a 215mm wall Brick or concrete infill between beams when they are staggered over. Each of these three beam and block types is again split by beam section block density and superimposed load.

Our floors are made by laying a series of T beams parallel to each other on supporting blockwork walls. Typically concrete masonry units have nominal face dimensions of 8 in. Beams are placed at appropriate centres depending on span and applied load.

These load span tables are split into three types wide centres Full width 440mm alternating wide and narrow centres Full width 440mm and narrow width 215mm and narrow centres Narrow width 215mm. Slip block 73Nmm or split course by the Builder. The density of block is.

We also provide concrete block flooring products with standard 100mm deep building blocks to span the gaps between the beams during installation. Note that for domestic garages a 75mm mesh reinforced screed applied. The distance that needs to be spanned.

Coursing Block - is a 440mm x 100mm x 90mm block that sits on the foundation blockwork under the outer skin of the cavity wall to align the internal and external courses. For example when the beam and block slab is placed it may be 100mm below external door openings meaning 100mm screed is required to level the floor. Equally a 50mm space means 50mm screed The span of the floor.

At Floorspan we produce 3 types of beam. Beam depth and profiles are selected according to span and loading requirements along with the type of block specified. Battens must be placed near the ends of the beams and in line with each other throughout the height of the stack.

Concrete Floor Beams Our Concrete Floor Beams provide the perfect solution to high quality economical concrete floor construction saving not only time but cost. Slip Bricks - a 385mm x 100 block which can be used either below the beam ends or above the beams ends to assist in alignment of internal and external courses. For assembled ceiling structures panels Hurdis beams etc where the ring beam has to end below the ceiling structure building blocks of 190 mm height can be used eg KB 101-20 A or KB 101-21 B etc.

203 mm by 16 in. In some cases a ring beam with sufficiently sized reinforcements may perform the function of lintels over windows and doors. The pattern and type of beam used for a floor depends on two main factors namely.

SUSPENDED BEAM AND BLOCK FLOOR WIDE BEAM 125mm 170mm 155mm 54 kgm Section weight Span up to 675m Lighter choice commercial solution compared to 225 deep beam Wide beams mean a faster installation due to fewer units to lift simpler layout and less grouting Available from 4m TWO SOLUTIONS Wide floor beams can span longer distances and.
