Definitions

  • the formwork is generally constituted from a framework formed by a set of metal or wooden plates conveniently arranged to receive the concrete that, when hardened, forms the walls walls or work elements constructed with this material, which , depending on the type of construction they will take a form one another.
  • Each of said surfaces is constituted by a plurality of hollow and equal slats, which according to the type of construction to which they are intended may be longitudinally slightly curved, for example for the realization of curved surfaces, or be flat, and in suitable number to form the structure that is convenient, being longitudinally joined together, which, preferably made of plastic material, will be obtained by extrusion, so that the length or height thereof will not be restricted, and can be cut as required by a size or another depending on the height of the structure to be built.
  • the inclusion in its interior is provided, which is hollow and equipped with a series of longitudinal reinforcement partitions that they divide their interior into cells, of metal profiles that, adjusted to some of said cells, will give total rigidity to the slats and consequently to the structure of the formwork.
  • the special geometry of the described slats also allows, and advantageously, their transport individually or together, winding the surface, formed by the longitudinal union of the number of slats that is convenient, wound on itself in a spiral.
  • the invention foresees the use of other trapezoidal and special design slats suitable to be fixed laterally to each other until form a conical cover, to later deposit the concrete.
  • Figures 2-B and 2-C- show respective details of the reinforcement metal profile introduced inside the slats and the configuration of the tongue and groove ends thereof.
  • Figures 4-A and 4-B. - They show in detail the two possible positions of the union between the slats.
  • Figure number 9. Shows a perspective view of the configuration of the additional inner support bars in the case of closed structures, such as the cylindrical that has been taken as example.
  • Figure number 12.- Shows a perspective view of the alternative embodiment of internal metal structure for the realization of circular structures.
  • Figure number 13. Shows a detail of the T-configuration of the end of the crosshead of the structure represented in Figure 12.
  • the formwork system in question is essentially formed from two parallel surfaces, (cylindrical and concentric in the case of the example shown since it is a circular tank), an exterior (1) and an interior (2), between which a ferrule mesh (3) is installed, leaving the hollow between them prepared to pour into it the fresh concrete.
  • Said ends have the male end (4a), an inner arrow shape (14) arranged between longer walls (15) and bent at its ends (16), design specially studied to fit with some flexibility, in two different positions, one more open and one more closed, as appropriate, as seen in Figures 4-A and 4-B, on the female end (4b) of the adjacent plank , thanks to said female end (4b) having a groove (17) in the form of an arrow suitable for receiving the aforementioned arrow (14) and two pairs of grooves (18) intended for the angled ends (16) of the male end (4a) ) arranged some closer to the end of the slat (4) and the others further inwards, being able to make them distance or approach and, if appropriate, can rotate slightly with each other to a certain limit angle, thus adjusting exactly Ia length and diameter of concentric or parallel surfaces (1 ) and (2) to the length required to be able to conform the different diameters or structures that are required in each case.
  • the formwork can be removed, following the steps described in reverse order and ultimately eliminating the threaded area (6) of the spacers (5), which after the removal of the nuts (7 ) It will protrude internally and externally from the walls of the structure, thus leaving the smooth surface and the body thereof prepared for the placement of the dome if appropriate.

Abstract

L'invention concerne un système de coffrage perdu en matière plastique, formé de deux surfaces parallèles, l'une extérieure (1) et l'autre intérieure (2), constituées d'une pluralité de lames creuses (4) en matière plastique obtenues par extrusion et longitudinalement courbées ou planes, pourvues de profils métalliques intérieurs (13) destinés à les rigidifier et assemblées longitudinalement à l'aide d'extrémités rainurées et languettées (4a et 4b), des séparateurs (5) étant situés entre les deux surfaces, pourvus d'une zone filetée (6) et d'un appendice oblique (8) pour soutenir Ia maille de fer (3) située entre les deux surfaces. La fixation au sol des lames (4) est garantie par des pièces (9) en U, renfermant une tige filetée (10) qui permet de retenir et de fixer la pièce pouvant incorporer dans des structures fermées des éléments internes de renfort du diamètre, tels que des barres métalliques (11) pourvues de platines (12) au niveau de leurs extrémités pour permettre leur fixation à la surface intérieure (2).
