  2. Beam and block - Wikipedia

    en.wikipedia.org/wiki/Beam_and_block

    Beam and block is a construction method to support flooring, especially for ground floors as well as multi story buildings. [1] It is made of cast concrete, one piece of which is a prestressed concrete beam, which can be an inverted T-shaped beam, or lintel, the other piece being a simple rectangular block. [1]

  3. Lintel - Wikipedia

    en.wikipedia.org/wiki/Lintel

    Modern-day lintels may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a suspended-floor concrete slab. An arch functions as a curved lintel. [1] [2]

  4. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    A common type of insulated slab is the beam and block system (mentioned above) which is modified by replacing concrete blocks with expanded polystyrene blocks. [11] This not only allows for better insulation but decreases the weight of slab which has a positive effect on load bearing walls and foundations.

  5. Rim joist - Wikipedia

    en.wikipedia.org/wiki/Rim_joist

    In flooring construction, the rim joists sit on the sill plates; in deck construction, they are parallel to the support beams and sit on the beams or in some cases, cantilever away from the beams. A double thickness board in the position of a rim joist is called a flush beam and serves a dual purpose, providing primary support for the joist ...

    The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3] The width of the solid area around the column should be 1 ⁄ 8 of the span between columns. Its height should be the same as the ribs. [3] Diagram showing waffle slab rib and Beam Heights rule of thumb formulas.

  7. Double tee - Wikipedia

    en.wikipedia.org/wiki/Double_tee

    Diagram of double tee beam. A double tee or double-T beam is a load-bearing structure that resembles two T-beams connected to each other side by side. The strong bond of the flange (horizontal section) and the two webs (vertical members, also known as stems) creates a structure that is capable of withstanding high loads while having a long span.

  8. Lift slab construction - Wikipedia

    en.wikipedia.org/wiki/Lift_slab_construction

    Axon and elevation diagram of lift slab construction. Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the ...

    sleeper wall is a short wall used to support floor joists, beam and block or hollowcore slabs at ground floor. It is constructed in this fashion when a suspended ...
