Definitions
- the invention refers to a structural system designed for reinforced or prestressed concrete building structures, made up of semi-prefabricated beams using reinforcement and a concrete slab in a lower arrangement whose edge thickness is of the order of 4 or 5 cm, assembled with plates. and with the pillars by means of a formwork platform adhered to the sheet metal of the pillars or to the pillar itself.
- This system of structures has a universal character of use: homes, commercial galleries, car parks, industrial warehouses, with or without a false ceiling, or plaster, or direct painting, or exposed concrete.
- the forged or unidirectional structure is the most widespread and used for the execution of houses in block or single-family, and is based on the use of joists or vaults to form the slab, and since they transmit their loads in only one direction, they are called unidirectional.
- the joists transmit their load to the beams that are ultimately responsible for transmitting all the weight to the pillars and through these to the foundation. It is currently the cheapest system for homes.
- the waffle slabs differ from the previous ones in transmitting their loads in two directions, forming a grid with their load ribs. Through this grid, the loads are finally transmitted to the pillars. They are used especially in office buildings, car parks, shopping centers, allowing the pillars to be further distanced than with the joist and vault slab. This system begins to be competitive in price in relation to the unidirectional system from spans of 7 meters between pillars.
- Precast slabs are currently used for large shopping centers or car parks, they are the most economical but they have the drawback that the grid formed by the pillars must be very regular, not allowing major architectural variations with their design.
- This formwork consists of placing two wooden or metal beams (trusses) parallel to the future beam and separated by 80 or 100 cm, then the boards that will form the bottom of the beam formwork are placed on these two trusses.
- the trusses are suspended in the air by means of metal props, placing pairs of props every meter. To avoid movements, the formwork is attached to the pillars and then the iron of the beams is placed from pillar to pillar.
- the structure is completed by means of joists and a vault that, leaning on the boards of one beam, will reach the boards of another beam and will cover the entire surface that was free to complete the structural plate. Every meter and a half it is necessary to shore up the joists since they are not self-resistant by themselves.
- edges of the structural plate require placing on the boards that form the bottom of the edge beams some metal or wooden risers that will give the shape to the perimeter of the structural plate and will serve as an "in situ" mold for the concrete that is poured. on the plate.
- the trusses and boards can be removed after three days, but the plate props must be left until 28 days, at which time ⁇ e will remove all the material, leaving the plate ready for use in masonry.
- the innovation of the invention lies in the combination of a series of well-known classic elements that determine new effects that provide greater speed in the execution of the structure and greater savings in formwork raw materials, with the consequent decrease in construction prices. the structures and consequently of the dwelling.
- This structural system for reinforced or prestressed concrete building structures is made up of semi-precast beams using reinforcement and a concrete slab, assembled with plates and with the pillars by means of a formwork platform attached to the plate of the pillars or to the pillar itself.
- the semi-finished beams rest on a formwork platform located around the pillars, absorbing any incidents in tolerance and stakeouts that occur on site.
- the slab or even other load-bearing beams are supported on the slab or sole of the semi-precast beam, and it can be the slab slab with ribs or the prestressed type with a ceramic, concrete, porexpan, etc. vault.
- the platform around the pillars can be created without having yet removed the formwork from the pillars (it can even be concreted pillars and slab at the same time).
- Said platform anchored to the formwork of the pillar or to the pillar itself may have different construction solutions and be made of wood, plastic, sheet metal, etc., made up of a classic formwork board.
- the semi-prefabricated beams supported on the platforms of two adjoining pillars will be placed props every certain distance to support their own weight and that of the slab that rests on its lower slab or sole.
- the slab may or may not have girders depending on the type used.
- the edge beams may have one of their sides completely finished with the same edge as the structure plate, thus avoiding the formwork with risers on site. Only in the immediate vicinity of the pillar and on the formwork platform will it be necessary to use finishing risers.
- the formwork of the pillars can be used to support the precast beams, not removing said formwork until the second or third day after concreting the plant.
- the column formwork incorporates a height regulator to favor stripping and adjusting the height of the floor.
- the speed of execution with respect to the classic girder and unidirectional slab structure will decrease in the order of 30 to 50% of the time currently used (depending on the type of slab used).
- the improvements introduced by this invention are: savings in formwork time and therefore greater speed of execution, a solution to any architectural construction typology of the structural plate (angled, dropped, edge beams, broaching, elevator shafts and patios, flights , inclined, etc.), cleanliness of the work, savings in nails and wood, savings in stripping time as there are no boards or formwork beams, longer duration of the formwork to avoid breakage of material in stripping, greater security for the formworker when constructing the formwork.

- the invention consisting of a semi-prefabricated structure of reinforced or prestressed concrete for building is made up of a horizontal formwork platform (1) located on the formwork (2) of the pillars or on the sides of the pillar. already concreted for the support of semi-prefabricated beams (3) and forged (4), with the semi-prefabricated beams (3) formed by lattices or steel stirrups (5) with a concrete slab or sole (6) at the bottom.
- the slab (4) is supported on the concrete slab or sole (6), which can be of any type already known today or can also support other load-bearing beams (7).
- the semi-precast beams (3) supported on the platforms (1) of two adjoining pillars are supported by struts (8) every certain distance to support their own weight and that of the slab (4) that rests on its lower slab or sole. (6) .
- the semi-precast beams can be edge beams (3'), presenting a lower L-shaped slab (6') that is located on its lower surface and covering one of the sides.
- the finishes are executed around the pillars with risers (9) and wood on the formwork platform (1).
- the pillar formwork incorporates a height regulator (10) to favor stripping and adjusting the height of the floor.
