Definitions

  • the present invention relates to the building industry and, in particular, to the sector of self-supporting beams for doors and windows as described in the preamble of Claim 1 and to the use of the said beams in mixed steel-and-concrete frameworks as described in Claim 4.
  • Beams are building components made of squared tree trunks or similar steel or reinforced-concrete structures, which are placed horizontally or in an inclined manner in order to support the weight of structures above them and to transmit the thrust produced thereby to vertical structures. Furthermore, beams are structural elements with one dimension, i.e. length, usually much greater than the other two, namely height and width. Beams withstand loads, mainly by bending, and also vertical gravitational forces. Beams are further characterized by their profile, which for example can be L-, U- or I-shaped, and by the material from which they are manufactured.
  • the subject of the invention is a self-supporting beam; within the context of the present invention, self-supporting refers to an element or structure which, as well as serving a predetermined function, also has supporting functions. Furthermore, the beam which is the subject of the invention has been subjected to punching, where punching means cutting out closed outlines and is done on sheets or metal sections in order to remove circular or variously shaped elements.
  • the purpose of the self-supporting beam T which is the subject of the present invention is to facilitate and speed up on-site installation as compared with known beams. Furthermore, the beam structure which is the subject of the invention has reduced weight and volume for improved transportation and storage of the beams in situ, in this case on a construction site.
  • the subject of the present invention is a self-supporting beam T for openings such as doors and windows, comprising at least one punched and profiled metal element 1 as described in the characterizing part of the attached Claim 1, and its use in a mixed steel-and-concrete reinforcement as described and defined in Claim 4.
  • a beam T which consists of a punched and profiled element having a U shape 1, made of metal, preferably stainless steel, with ribs 2 which are suitable for stiffening the element so that it can better withstand loads, mainly by bending, and also vertical gravitational forces.
  • the ribs 2 are both on the base of the punched and profiled element and on its sides.
  • the said element serves as a prefabricated structural load-bearing beam for the tops of the holes of openings, such as doors dividing inner rooms and windows.
  • the said U-shaped punched and profiled element 1 is manufactured so as to comply with the different standard thicknesses and widths of doorways.
  • Its characteristic ribbing 2 and punching is predetermined and it is dimensioned so that its capacity load is suitable for its use and also so that there is a good key for the plaster both inside and outside the section bar, i.e. the said U-shaped punched and profiled element.
  • the beam can be used as a prefabricated load-bearing reinforcement for small lofts.
  • Figure 6 shows a second embodiment, which is a punched and profiled element having an L-shaped profile 4, made of metal, with ribs 2 both on its base and on its side.
  • the said punched and profiled element having an L-shaped profile 4 is used in pairs, by joining two angle sections so that the particular ribbing on the base interlocks with the other, thereby creating a single U-shaped element.
  • the feature of having two angle sections 4, as shown in Figure 9, is that, when joined together, the said section bars form a single channel section, thereby making it possible to use two different metals, for example it is possible to use a stainless metal when manufacturing the section bar which will be used on the outward side, whereas the joined element is made of a different type of metal used on the inward side.
  • the beam can be used as a prefabricated load-bearing reinforcement for small lofts.
