Definitions

  • the present invention is related to a formwork member, and to a formwork obtained by assembling such member as well, a plant for the pouring and the curing using said formwork for making building elements as wall, basements, pillars etc.
  • the maturation consists in a chemical reaction of hydration: water reacts with the cement transforming the concrete grains in crystals which, interacting with each other, cure the element.
  • the concrete need to breath, because the hydration process is an exothermic reaction causing the water evaporation from the liquid concrete.
  • the weather conditions, in this phase, are fundamental because too low temperatures may produce ice crystals in the structure which, once melted, may weaken the resulting structure.
  • additives may be used in the concrete, but it is not desirable to not condition the concrete composition according to the weather. Further, the harshness of the climate may slow down the maturation process and influence the humidity content within the concrete.
  • Patent publications No. DE 19 17 398 A1 , US-A-2 602 210 , DE 23 09 104 A1 , US-A-5 595 171 , GB-A-1 063 738 and EP-A2-0 232 109 all discloses formwork members wherein an insulating layer is coupled with heating means.
  • the technical problem at the root of the present invention is to provide a formwork member and hence a formwork and a related method of pouring and curing allowing to obviate to the drawback mentioned with reference to the prior art.
  • the main advantage of the formwork member according to the present invention lies in allowing a temperature control of the maturation process, releasing it from the formwork external temperature.
  • the present invention is also related to a pouring and curing method, wherein the concrete is poured in a formwork carried out by formwork member as above defined, and wherein the heating layer of the formwork member is heated at least to a temperature of 80°C.
  • said heated layer is heated since 90 minutes after the curing starting, but preferably not later than 12 minutes.
  • a pouring and curing plant for the making of a building element comprises one or more formworks carried out by formwork members as above defined, and heating means of the heating layer of said formwork members.
  • a formwork including formwork members according to the preferred embodiment of the present invention is indicated 1 as a whole. It encloses a wall 2 in reinforced concrete and comprises opposing formwork members 3 to form a shell.
  • Each formwork member 3 comprises a framework 4 made of steel tubular members, supporting the body or the panel of the member, substantially plate-shaped.
  • the formwork member 3 comprises an insulating layer 5 made of an appropriate material, e.g. polyurethane or polystyrene with a suitable thickness, for example 40 mm.
  • the formwork member 3 further comprises a heating layer 6, adjacent to said insulating layer 5.
  • the insulating layer 6 is the first layer placed substantially adjacent to the concrete curing
  • the insulating layer 5 is the second layer placed at the exterior of said first heated layer.
  • the heating layer 6 is embodied by a pair of parallel sheets 7 enclosing heating members 8.
  • the sheets 7 are kept at a constant distance by spacing members 9, constituted by tubular sections longitudinally extending with respect to the heating layer 6.
  • the heating members 8 are carried out by pipes run through by a heating liquid, made of metal, preferably copper. It is understood that the heating members 8 are in thermal transfer communication with the concrete, the pipes being in contact with the steel sheet 7 which is in contact with the concrete.
  • the pipes are electrically insulated to not create dielectric bridges.
  • the sheet steel will be appropriately selected to allow the reuse of the formwork member.
  • the gap between the sheets 7 is suitably filled up with a thermal storage material, for example water-based, i.e. a mixture of water antifreeze agent, in appropriate proportions, e.g. 65%-35%.
  • a thermal storage material for example water-based, i.e. a mixture of water antifreeze agent, in appropriate proportions, e.g. 65%-35%.
  • the formwork 1 further comprises tie members 10 keeping the formwork members 3 in their position and crossing the above layers 5, 6, with nut-and-bolt works placed at the insulating layer 5. External posts 12 are also provided.
  • the framework 1 comprises a rectangular-shaped frame 20, with horizontal tubular sections supporting said layers 5, 6.
  • the pipes 8 extend between a pair of manifolds, delivery 21 and receiving 22.
  • the pipes can be coupled in parallel or in series, with a coil configuration.
  • a pouring and curing plant pf a building element comprises formworks as previously described, with framework members comprising heating members forming distinct thermal circuits indicated as A, B and C.
  • circuits are supplied with a heating fluid through a heat generator, a delivery conduit 31 and a return conduit 32.
  • the fluid circulation is driven by a station 33 having a circulation pump and a possible storage reservoir 34 constituting a fluid supply.
  • Said heat generator 30 is embodied by a boiler and constitutes heating means of said heating layers 5.
  • the fluid is a heat-carrier fluid suitable to this task. It can be water or comprise a mixture of water and an antifreeze agent, in suitable proportions, e.g. 65%-35%. A conventional antifreeze agent can be used.
  • the plant At the delivery conduit, the plant comprises a first delivery valve 36, a relief valve 40, a delivery thermometer 39.
  • the plant At the return conduit, the plant comprises a return thermometer 38, a by-pass valve 37 and a discharge valve 35.
  • circuits in which the plant is sub-divided are coupled in parallel, to minimize the temperature difference between the delivery and the return conduits.
  • the heating fluid into the heating members 8 is kept at a temperature of at least 80°C, preferably within the range of 80°-90°C.
  • the concrete quickly acquires its own compression strength in a reduced time, even two days.
  • the heating can be maintained for a period of 24 hours, in any case at least 8 hours.
  • the heating members can be made by electrical heater or by a hot-air circulation system in a gap within the heating layer.
  • the above described ducts 8 may be replaced by paths formed by leaves transversal to the sheets 7.
