Definitions

  • the present disclosure relates generally to devices for forming structures, and more particularly, but not necessarily entirely, to devices for forming pre-cast concrete columns.
  • Precast concrete structures have been used in the building construction industry for many years.
  • Precast concrete structures may include steel reinforced panels for use in constructing fences, walls, sound barriers, and the like.
  • Precast concrete structures may also include columns for supporting panels or overhead items.
  • High quality precast concrete structures may be formed efficiently, since they may be constructed in a factory with specialized equipment, strict quality standards, and controlled conditions not subject to rain, hot or cold temperatures, or builder errors.
  • labor savings may be accomplished since precast structures may be formed more efficiently in a factory than constructing a form on site to manufacture the structures in place.
  • Use of precast concrete structures may also reduce construction delays associated with rain or inclement weather since concrete may not be properly poured on site in inclement weather.
  • precast concrete panels may have various patterns such as stone or brick, for example. Such precast concrete panels may be easier to construct than stone or brick walls. Moreover, the precast concrete panels may be durable and provide advantages in that cracking may be reduced as compared to walls formed with grouted natural stone or brick, and no mortar joints are created with precast concrete panels to allow water to seep into the wall. [0004] Various types of devices are known in the art for forming precast concrete structures. Despite the advantages of known devices for forming concrete structures, improvements are still being sought to improve the efficiency of the manufacturing process and the quality of the concrete structures.

Abstract

L'invention concerne une cavité pour former des structures de béton précoulées, telles que des colonnes de béton. La cavité peut être définie par un organe de base et deux organes latéraux opposés. Les deux organes latéraux opposés peuvent être interconnectés de façon pivotante à l'organe de base, de telle sorte que les deux organes latéraux opposés sont mobiles entre une position prête à l'emploi et une position de libération. Des organes de projection peuvent être placés dans la cavité pour former des fentes dans des colonnes formées dans la cavité. Les fentes sont adaptées pour recevoir les extrémités terminales de panneaux en béton. Des coffrages peuvent être installés de façon amovible dans la cavité, pour faire varier une dimension des colonnes de béton formées à l'intérieur.
