Abstract

The present invention relates to a prefabricated panel for the construction of enclosures which features an upper and lower grooving which permits, once the mortar used to join the panels has been poured, the array of panels thus formed to act as a single element, and also relates to an enclosure which comprises at least a prefabricated panel of those mentioned above that is parallel to another wall and wherebetween insulating means, preferably an air chamber, are provided, thus constituting a ventilated facade.

Description

    OBJECT OF THE INVENTION
  • The present invention relates to a prefabricated panel for the construction of enclosures with which the construction of an enclosure is carried out, that absorbs the shear stresses produced in the direction perpendicular to the plane of the enclosure, thus preventing separation between the different panels which make up the enclosure.
  • The object of the invention consists of a prefabricated panel which features an upper and lower grooving that permits, once the mortar used to join the panels has been poured, the array of panels thus formed to act as a single element.
  • Due to its special configuration, the prefabricated panel of the present invention features additional means which facilitate the joining to the adjacent panel, these additional means increasing the rigidness of the panel against shear stresses.
  • Likewise, another object of the present invention is an enclosure which comprises at least one prefabricated panel of those mentioned which is parallel to another wall and wherebetween insulating means are arranged.
    • BACKGROUND OF THE INVENTION
  • Prefabricated panels made of reinforced concrete with natural stone or similar faces are known in the state of the art, particularly applicable in coatings and floors, which are made up of a reinforced concrete base, of the desired dimensions and whereto the pieces of natural stone or similar remain fixed after hardening, arranged with the chosen distribution across the entire moulding surface.
  • Among these is Spanish Utility Model ES1053364U , which uses an array of panels of those described above, making use of a template for placing the natural stone or similar.
  • However, when the preceding prefabricated panel is used to build a vertical enclosure, it is necessary to use additional fixing or joining means between panels so that the resulting shear stresses produced in the direction perpendicular to the plane of the enclosure can be absorbed by the enclosure.
  • These additional means require a much slower and more costly installation process, due to the fact that an in situ or prior fixing thereof must be carried out to prevent that displacement in the direction perpendicular to the plane of the enclosure.
  • Likewise, enclosures which feature two parallel walls wherebetween insulating means are provided are known in the state of the art. These enclosures are known by the term "cavity wall".
  • The prefabricated panels from the Spanish Utility Model ES1053364U cannot be used in the previous type of enclosure since when the insulating material is air; there is no support surface for the panels to absorb the stresses in the direction perpendicular to the panel.
  • The prefabricated panel for the construction of enclosures of the present invention resolves all of the abovementioned drawbacks with a configuration which absorbs the shear stresses produced in the direction perpendicular to the plane of the enclosure.
  • Likewise, a ventilated facade wherein the exterior wall features a stone, brick, synthetic or similar material appearance constituted from prefabricated panels with a concrete, mortar or similar base and with sufficient structural rigidity and suitable ventilation conditions to meet the current ventilated facade regulations, can be formed by means of several prefabricated panels for the construction of enclosures of the present invention.
    • DESCRIPTION OF THE INVENTION
  • The present invention relates to a prefabricate panel for the construction of enclosures with which the construction of an enclosure is carried out which absorbs the shear stresses produced in the direction perpendicular to the plane of the enclosure, thus preventing separation between the different panels which make up the enclosure.
  • The prefabricated panel comprises a concrete, mortar or similar base of certain dimensions whereto are fixed one or several blocks of stone, brick, synthetic material or similar, where the prefabricated panel thus constituted comprises an upper and lower grooving which permits, once the mortar used to carry out the joining between the panels has been poured into said grooving, the enclosure made up by the array of panels to act as a single element.
  • The prefabricated panel further comprises fixing means which facilitate the joining thereof to an adjacent panel, means which increase the rigidness of the panel against shear stresses.
  • The prefabricated panel of the present invention permits the forming of an enclosure where features at least one prefabricated panel arranged parallel to a wall or inner structural wall and wherebetween first insulating means or an air chamber are provided.
  • The joint between the wall and the prefabricated panel(s) is carried out by means of anchoring means or locking pins which additionally set the distance between both the wall and the prefabricated panels.
  • These anchoring means or locking pins support both the inner wall or side and the upper grooving of the prefabricated panels and pass through routing at the same height as the upper grooving provided in the inner face of the prefabricated panel.
  • The prefabricated panels which form one of the parts of the enclosure comprise one or more vertical through holes wherethrough vertical rods are arranged that link and connect the prefabricated panels and stiffen the enclosure.
  • The enclosure further comprises rods or horizontal stiffening means that are embedded in the mortar and provided in each joint between two prefabricated panels, which permits the reinforcement of the horizontal joint in said joints, which are critical points regarding structural rigidity.
  • The enclosure further comprises support profiles which are anchored to the inner wall or side of the enclosure, which is the one that supports the load, and which are provided every certain number of vertically arranged prefabricated panels.
  • The enclosure further comprises expansion joints, which can be provided underneath the support profiles, to absorb the expansions and contractions of the prefabricated panels of the enclosure.
  • The enclosure further comprises second insulating means provided between the first insulating means or air chamber and the structural inner wall or side.
