Joist Flooring in a Block House

For block house constructions, our selection of wooden joist flooring systems offers unparalleled strength and stability. With options including double joists for added support, our solutions are ideal for high-traffic areas and ensure a solid foundation that can withstand the test of time. These flooring solutions not only enhance the structural integrity of your block house but also contribute to its overall aesthetic appeal, creating a harmonious blend of form and function.

Node 1: Support of I-beam joists on screed over blocks

This method is the best and most commonly used solution. The node is applied when floor joists (interfloor, basement, or attic) rest on reinforced screed over blocks with the space between the beams filled with blocks at supports. To reinforce the I-beam at the support point, inserts made from OSB, plywood, or board can be used. The insert should have a 5 mm gap from the top flange of the I-beam, and its width should be at least 30 cm. The beams should rest 15 cm on the wall. All wooden structures must be protected from contact with concrete by waterproofing.

Materials and Components:

 

  1. Wooden I-beams (main joists)
  2. Blocks
  3. Waterproofing (hydro barrier or mastic)
  4. Cement-sand screed (reinforced)
  5. Insert made of OSB-3/plywood/board, 30 cm wide
  6. Filling (cement; expanding foam)

  4. Filling (insulation; expanding foam)

Node 2: Support of I-beam joists on blocks

When using wall blocks with high load-bearing capacity and where heavy loads on floor joists are not anticipated, I-beams can be directly supported on the blocks. The minimum support size should be 10 cm, with 15 cm being optimal. Wooden structures must be protected from contact with blocks/cement using a waterproofing material. The space between the flanges of the I-beam should be filled with insulation or expanding foam.

Node 3: Support of I-beam joists on screed over blocks with bricks between the beams.

This method is used if it is decided to end the beams with bricks. The advantages of this approach include the ease of installing I-beams, the ability to space joists at any interval, and increased structural rigidity of the wall. The downsides are an increased load on the foundation and additional costs if no other brickwork was planned.

Materials and Components:

 

  1. Wooden I-beams (main joists)
  2. Blocks
  3. Bricks
  4. Cement-sand screed (reinforced)
  5. Waterproofing (hydro barrier or mastic)

Materials and Components:

  1. Rough covering (OSB-3 panels, plywood, boards)
  2. Vapor barrier
  3. Insulation
  4. Wooden I-beams (joists)
  5. Vapor barrier or waterproofing
  6. Lathing on the lower flange of the I-beam (strips of OSB-3, plywood, or timber) 

This setup effectively combines multiple layers to enhance both sound and thermal insulation, ensuring a robust and energy-efficient floor structure.

Node 4: "Layer Cake" Flooring Variant

This method involves the use of mineral wool or basalt fiber insulation as soundproofing and thermal insulation materials.
