Definitions

  • the invention relates to a structural system conceived for reinforced or pre-stressed building structures formed by semi-prefabricated beams and inferior arrangement concrete reinforcements and slabs having an edge thickness in the order of 1 to 5 cm assembled with plates and pillars by means of a planking platform secured to the pillar planking or to the pillar itself.
  • This form of attachment provides an economic solution for any type of structural tie, either straight, angled, non-aligned, or for hanging, edge, or corner beams, or yard, or three or four beams, etc.
  • This structural system is of a universal character in regard to use, serving for houses, commercial galleries, car parking buildings and industrial buildings, with or without a false ceiling and with a plastered, directly painted or visible concrete finish.
  • the currently used systems for building structures are classified in three types:
  • the unidirectional framework or structure is the most extensively used for block buildings or single-family houses, and it is based in the use of girders or slabs to form the framework; since they transmit their loads in one single direction, they are known as unidirectional.
  • the girders transmit their load to the beams, which in turn transmit the whole weight to the pillars and through these to the foundation. At present, this is the least expensive house building system.
  • Reticular frameworks are different from the above in that they transmit their load in two directions, forming a reticule with their load nerves. The loads are finally transmitted to the pillars through this reticule. They are used particularly for office buildings, car parking buildings and commercial centers, and allow for more spacing between the pillars than with girder and slab frameworks. This system is now starting to be competitive in price, in relation to the unidirectional system, as from 7-meter spans between pillars.
  • Prefabricated frameworks are presently used for large commercial centers and car parking buildings. Although they are more economical, they present a drawback in that the grid formed by the pillars must have a very regular shape which does not allow for great architectural design variations.
  • the location of the house pillars are first laid out on the floor, then the planking is put in place and the pillars are filled with concrete.
  • the pillar planking is removed the next day, and the planking of the main load beams is started.
  • the planking consists in placing two wooden or metal beams (crosspieces) parallel to the future beam and separated 80 to 100 cm from each other; panels are then placed on top of these two crosspieces to form the bottom of the beam planking.
  • the crosspieces are suspended in the air by means of metal struts installed in pairs every one meter. In order to avoid movement, the planking is secured to the pillars, and iron rods are then installed in one pillar after the other.
  • the structure is completed by means of girders and slabs which rest on one beam panel and reach out to another beam panel to cover the whole previously empty surface in order to complete the structural plate.
  • the girders must be propped-up every meter and a half or so, since they are not self-supporting.
  • edges of the structural plate require that metal or wooden partitions be placed over the panels which form the bottom of the edge beams, so as to give the structural plate perimeter its shape and serve as an on-site mold for the concrete poured over the plate.
  • the crosspieces and panels may be removed three days later, although the plate struts must be left in place up to 28 days, after which all the material is removed, the plate being ready for masonry work.
  • the innovation of the invention lies in combining a series of known classical elements which determine certain new effects which allow for greater speed in the execution of the structure and savings in planking material, thus reducing the price of the structures and consequently of the house.
  • This structural system for reinforced or pre-stressed concrete building structures is formed by semi-prefabricated beams with reinforcement and concrete slabs that are coupled onto the plates and pillars by means of a planking platform secured to the sheet of the pillar or to the pillar itself.
  • the semi-prefabricated beams rest on a planking platform located in the proximity of the pillars, and absorb all the defects in regard to tolerance and laying out at the work site.
  • the platform around the pillars may be created before removing the planking from the pillars (the concrete may even be poured into the pillars and the framework simultaneously).
  • Said platform anchored to the pillar's planking or to the pillar itself offers different construction solutions, and may be made of wood, plastic, metal plate, etc., to form a classic planking panel.
  • the structure's horizontal movement or bending is completely avoided by means the pillars previously filled with concrete or by the pillar planking duly adjusted, plumb lined and propped-up.
  • the semi-prefabricated beams which rest on the platforms of two adjacent pillars are fitted with spaced struts which support their own weight and that of the framework resting on the slab or inferior sole.
  • the framework may or may not be provided with joists, depending on the type used.
  • the edge beams may have one of its sides fully finished with the same edge as the structure plate, thus avoiding the planking with partition at the work site. Finishing partitions are needed only in the proximity of the pillar and on the framework platform.
  • planking is removed once the concrete has been poured to form the pillars.
  • the pillar planking construction may be used for supporting the prefabricated beams; said planking is not removed until the second or third day after pouring the concrete on the floor.
  • the pillar planking incorporates a height adjustment element to aid in the planking removal and in the adjustment of the floor height.
  • the advantages provided by the invention include time saving in planking operations, and therefore increased execution speed, solutions for all kinds of architectural constructions of the structural plate (angle, hanging, edge and support beams, elevator ducts, yards, projections, slants, etc.), tidiness at the work site, saving in nails and wood, time saving in planking removals in view that no planking panels and beams are involved, longer plank mold life in view that material damages are avoided during planking removals, and safer conditions provided to the planking installator.
  • the invention consisting in a reinforced or pre-stressed concrete semi-prefabricated structure for buildings is composed of a horizontal planking platform (1) positioned over the planking (2) of the pillars or on the sides of the pillars on which concrete has already been poured designed to Support the semi-prefabricated beams (3) and framework (4), said semi-prefabricated beams (3) being formed by steel louvers or joist hangers (5) with a concrete slab or sole (6) on their lower part.
  • the framework (4) which may be of any currently known type and may also serve to support other load beams (7).
  • the semi-prefabricated beams (3) resting on the platforms (1) of two adjacent pillars are supported by struts (8) positioned at a given spacing, designed to withstand their own weight and that of the framework (4) resting on the lower slab or sole (6).
  • the semi-prefabricated beams may be edge beams (3') which show an inferior L-shaped slab (6') positioned in its lower surface and which covers one of the sides.
  • the finishing is performed around the pillars using partitions (9) and wood over the planking platform (1).
  • the pillar plankings incorporate a height adjustment element (10) to aid in the planking removal and the adjustment of the floor height.
