Definitions

  • This invention has for its object a prefabricated vertical one-piece element made of reinforced concrete, for erecting the skeleton of a building, and the like, and contemplates also a building skeleton that is formed by using these prefabricated vertical elements, as well as a form for manufacture of the said element.
  • the invention aims to realize a prefabricated vertical element of the aforementioned kind, that is extremely strong from the static view point, but very light at the same time, and that can be used for quite a variety of building structures, while permitting an easy and quick installation.
  • a prefabricated vertical one-piece element made of reinforced concrete and characterized in that it consists of four posts that are located at the angles of a quadrangle, and that at a certain level are interconnected by horizontal crosspieces extending along the sides of the quadrangle.
  • the four posts are located at the angles of a rectangle, more particularly of a square, whereby the use is permitted of the prefabricated vertical elements according to the invention in the usual type of skeletons with right-angle frames.
  • the horizontal cross pieces for the prefabricated vertical elements of the invention may be provided either at the bottom end section of the posts or at the top end section thereof.
  • the horizontal cross pieces are located at an intermediate level of the posts, more particularly in a median area between the ends of said posts.
  • the crosspieces of the prefabricated vertical element may be either straight pieces, or may consist of arches, such as, for example, Roman or depressed arches, or ellipitic or mixed arches, with the extrados upper surface of the arches being preferably flat, whereby to obtain their adaptability to any of different architectural requirements.
  • one or more through holes can be provided for allowing pipes, cables, or the like, to be passed therethrough.
  • These holes for the beam- and/or floor-anchoring means can be obtained in a very simple manner when they are formed from one or more grillworks of tubes being incorporated in the prefabricated vertical element.
  • Such a joint prevents any reciprocal side displacement between two superimposed prefabricated vertical elements, and guarantees a sufficient connection between these elements, even with no reinforcing vertical through rods.
  • the particular construction of the prefabricated vertical element according to the invention permits to obtain very high moments of inertia, although very slender structures are adopted, which leads to a considerable light weight of the prefabricated vertical elements.
  • This light weight allows to considerably economize in the conveyance and the lifting of the prefabricated vertical elements, while it gives rise to an appreciable reduction of the loads on the foundation under the same external stresses.
  • the prefabricated vertical element according to the invention furthermore has a great stability and the capability of absorbing any side thrust in every direction, so that it is particularly fit for being employed in seismic regions, since the need is avoided of additional metal reinforcements in the reinforced concrete.
  • the prefabricated vertical element according to the invention while maintaining its relative light weight, may be of any desired, even considerable dimensions, which allows to erect buildings of great proportions in a short time.
  • the prefabricated vertical elements of the invention are self-supporting, whereby it is avoided to have resort to any supporting fixture and framework. When erecting the skeleton of a building, it is possible to superimpose two, three, or more vertical elements without any horizontal frame being required.
  • the prefabricated vertical elements of the invention may be used in any desired manner and in any type of building skeletons.
  • a building skeleton comprising pillars that are connected by means of horizontal beams and/or floors, at least one pillar is formed by two or more prefabricated vertical one-piece elements of reinforced concrete, made according to the invention, and placed the one upon the other.
  • the joints between the posts of two superimposed prefabricated vertical elements are not flexure stressed, so that it is possible to do without any particular flexure-resistant connection between the posts of the superimposed vertical elements, and the said male and female joint between the posts, in correspondence of the junctions, and possibly with the interposition of a layer of a binder or a glue, is sufficient for guaranteeing a reliable bond between the superimposed prefabricated vertical elements.
  • the superimposed vertical elements of two pillars are interconnected at the level of a floor and in correspondence of their posts and the adjoining ends of their crosspieces, by two spaced apart, parallel horizontal beams, while the space between these beams is covered preferably by means of prefabricated tiles being laid on the beams, and is intended for accomodating pipes, cables, and the like, for the several systems of the building.
  • the space inside at least one of the pillars in the skeleton which consists of two or more superimposed prefabricated vertical elements, may be left entirely or partly clear of internal horizontal partitions, so as to form a continuous vertical shaft for the installation of a lift, of a staircase, and/or of pipes, cables, or the like, for the several systems of the building.
  • all the pipes for any installed system can be arranged within the building skeleton-lightening spaces, whereby a high degree of independence between carrying structures, internal partitions, and installed systems, is obtained.
  • slabs may be provided, particularly at the level of the crosspieces in said elements, whereby to form dwelling or duty rooms, office or trade premises, or the like, at the interior of the pillar.
  • numeral 1 denotes a prefabricated vertical element made of reinforced concrete for building skeletons.

  • the bottom ends of posts 2 of the first prefabricated vertical element 1, 1' are fixed by their bottom end projections 7 in mating top end recesses 8 provided in the top ends of posts 10 of the base element 9.
  • the ends of posts 2 of the several superimposed vertical elements 1, 1' are fixed to each other.
  • bearing metal frames 12 extending all around the respective post-fixing projections 7 and recesses 8, are preferably interposed. These bearing frames 12 space apart the post-fixing projections 7 and the respective post-fixing recesses 8, and the resulting gap is filled with a suitable binder 13, for example, with cement, or possibly even with a glue, as it clearly appears in Figure 5.
  • the superimposed vertical elements 1, 1' are interconnected by means of horizontal beams and/or floors. These beams and these floors may be made, and may be connected to the pillars in any suitable manner, more particularly they may be either entirely or partly prefabricated, or entirely or partly prefabricated, or entirely or partly cast in situ.
