Definitions

  • the present invention relates to the field of structural units, and more particularly to the field of fast erection light structural units.
  • Structural units are known. They vary in the constructional materials they are made from, and, in the erection methods. The most common structures are made of concrete with reinforcing steel. These structures are very strong, however, they are very heavy, expensive, and require relatively long erection period; preparation of molds, long curing periods of the concrete, laboratory tests for verifying final strength, etc.
  • the light cover may consist of an aluminum frame onto which are assembled glass plates, gypsum plates, and the like.
  • a structural unit is formed from structural elements that are connected to each other in a simple manner. When all the structural elements are attached to each other, the structural unit may form a strong and rigid structure up to five stories high.
  • the advantage of the structural element of the present invention is that construction of a structural unit with a separate frame onto which a cover is assembled is successfully prevented.
  • the structural unit includes both a frame and a cover formed using the structural element of the present invention.
  • a structural element including a substantially flat central portion, a first web portion perpendicularly extending from an edge of the central portion, and a second web portion perpendicularly extending from an opposing edge of the central portion.
  • the central portion and the first and second web portions are formed from a unitary steel sheet.
  • the structural element is suitable for forming load bearing floors and/or walls in a structure.
  • the first and second web portions include a flat portion and at least one longitudinally extending ridge.
  • the flat central portion includes one or more longitudinally extending ridges.
  • the first and second web portions include an inwardly directed end bend directed in a direction towards the central portion.
  • the first and second web portions include an outwardly directed end bend directed in a direction away from the central portion.
  • the first web portion includes an inwardly directed end bend directed in a direction towards the central portion and the second web portion includes an outwardly directed end bend directed in a direction away from the central portion.
  • the at least one longitudinally extending ridge is inwardly directed in a direction towards the central portion.
  • the at least one longitudinally extending ridge is outwardly directed in a direction away from the central portion.
  • a structural unit formed from a plurality of structural elements, each structural element having a substantially flat central portion, a first web portion perpendicularly extending from an edge of the central portion, and a second web portion perpendicularly extending from an opposing edge of the central portion.
  • the central portion and the first and second web portions are formed from a unitary steel sheet.
  • the structural element is suitable for forming load bearing floors and/or walls in a structure. Also included is a ground slab to support the structure.
  • the first and second web portions in each of the structural elements include a flat portion and at least one longitudinally extending ridge.
  • the structure includes a frame formed using the structural elements.
  • the structure includes one or more floors formed using the structural elements.
  • the structure includes one or more walls formed using the structural elements.
  • the structure includes a maximum of five stories.
  • FIG. 1 is a perspective view of a structural unit built using structural elements, according to an embodiment of the present invention
  • FIG. 2 is a perspective view of a structural element, according to an embodiment of the present invention.
  • FIG. 3 is a cross-sectional view showing the connection between the web portions of two consecutive structural elements, according to a first embodiment of the present invention
  • FIG. 4 is a cross-sectional view showing the connection between the web portions of two consecutive structural elements according to a second embodiment of the present invention
  • FIG. 5 schematically illustrates the construction of the balcony in the structural unit, according to an embodiment of the present invention
  • FIG. 6 schematically illustrates the construction of a wall in the structural unit, according to an embodiment of the present invention
  • FIG. 7 schematically illustrates the construction of a façade and roof in the structural unit, according to an embodiment of the present invention.
  • FIG. 8 schematically illustrates the construction of an internal floor and walls in the structural unit, according to an embodiment of the present invention
  • FIG. 9 schematically illustrates the construction of a floor and a wall (interior and/or exterior) in the structural unit, according to an embodiment of the present invention.
  • FIG. 10 schematically illustrates the construction of a floor (ledge) and exterior wall in the structural unit, according to an embodiment of the present invention.
  • FIGS. 1 to 4 show a structural unit 10 according to the present invention.
  • the structural unit 10 will hereinafter be called “unit”.
  • the unit 10 is formed from a plurality of structural elements 12 that make up the major portion of the unit 10 .
  • Each of the structural elements 12 is produced out of a steel roll, having a given width, which is rolled and cut to the desired shape and length.
  • Each of the structural elements 12 is formed from a unitary piece that comprises a central portion 14 and two web portions 16 extending perpendicularly therefrom.
  • the structural element 12 has an element length L and an element width W.
  • each of the web portions 16 comprises a flat web portion 18 and a longitudinally extending ridge 20 that increases the rigidity of the web portion 16 and hence of the entire structural element 12 .
  • the central portion 14 may be provided with a ridge, or a plurality of ridges, for increasing the total rigidity and bending resistance of the structural element 12 .
  • each of the web portions 16 is provided with an inwardly directed end bend 22 .
  • the end bend 22 significantly increases the rigidity of the web portions 16 and hence of the entire structural element 12 . Furthermore, the end bend 22 adds additional convenience and safety when transporting, conveying and using the structural element 12 .
  • the ridges 20 of the web portions 16 are inwardly directed, thus enabling easy abutment of the flat web portion 18 of a given structural element 12 against the flat web portion 18 of the consecutive structural element 12 .
  • the web portions 16 are then attached to each other by a multitude of self-drilling screws 24 .
  • the application of the self-drilling screws 24 is easy, fast, and does not require any specific accuracy.
  • the two structural elements 12 are rigidly attached to each other and form a single unit.
  • the web portions 16 are formed such that a first web portion of a given structural element is formed with the ridge directed inwardly, while a second web portion of the same structural element is formed with the ridge directed outwardly.
  • the two ridges fit into each other in a male-female manner, thus providing additional fit and sturdiness between the structural elements. It is clear in this case, that the male ridge should be slightly smaller than the female ridge in order to provide perfect fit therebetween.
  • the base foundation may be formed from gravel or concrete to suit the floor tiling that will be later applied thereon.
  • FIGS. 5 to 9 schematically illustrate exemplary connections of the structural elements 12 used to build the structural unit 10 , according to some embodiments of the present invention. Appropriate structural attachment elements are used to connect the structural elements 12 with other structural components.
  • FIG. 5 illustrates the construction of the balcony in the structural unit 10 (detail B) and includes multiple structural elements 12 horizontally and vertically arranged.
  • Horizontal structural elements 12 are laid over a horizontal beam 13 which is supported on one side by a column 17 and on the other side by a vertical structural element 12 which also forms the exterior wall of the unit 10 .
  • the horizontal structural elements 12 support a balcony deck structure 15 .
  • FIG. 6 illustrates the construction of a wall in the structural unit 10 (detail A) and includes vertical structural elements 12 attached to a floor 19 in one of the stories.
  • the vertical structural elements 12 may be covered by blocks or other type of coverings (e.g. gypsum boards, metal lathe and plaster, among other known covering).
  • FIG. 7 illustrates the construction of a façade and roof in the structural unit 10 (detail D) and includes multiple structural elements 12 vertically and horizontally arranged.
  • the horizontal structural elements 12 are supported at the ends by vertical structural elements 12 which also form a section of the façade of the structure 10 .
  • the horizontal elements 12 support the roof structure 23 .
  • FIG. 8 illustrates the construction of an internal floor and walls in the structural unit 10 (detail E) and includes multiple structural elements 12 vertically and horizontally arranged. As may be appreciated from the figure, the horizontal structural elements 12 form the floor and are supported by the vertical structural elements 12 which form the walls.
  • FIG. 9 illustrates the construction of a floor and a wall (interior and/or exterior) in the structural unit 10 (detail F) and includes multiple structural elements 12 vertically and horizontally arranged.
  • the horizontal structural elements 12 form the floor and are supported by the vertical structural elements 12 which form the walls.
  • the horizontal structural elements 12 on one side of the wall may be oriented perpendicularly to those on the other side of the wall.
  • FIG. 10 illustrates the construction of a floor (ledge) and exterior wall in the structural unit 10 (detail C) and includes multiple structural elements 12 vertically and horizontally arranged.
  • the overall strength and rigidity of the structural unit 10 is much stronger than the strength and rigidity of the individual structural elements 12 .
  • This form of building the structural unit 10 has been found to be efficient at least up to five stories height. In that manner, a cheap and fast erecting structure can be built, without the need of concrete columns or steel beams.
  • the structural unit 10 built according to the present invention enables considerable savings and advantages during the construction process
  • this structural unit may be used for building one, two, or up to five stories high.
  • the upper cover of the structural unit may be formed from structural elements as described above or similar thereto.
  • the structural elements may be provided with thermal insulation, as glass wool or the like, and closed by another sheet of metal, to form unit that is covered from its four sides.
  • Openings in the structural elements may be opened according to design needs.
  • steel beams may be added to the structural unit.
  • these beams are an addition only, and do not form an essential part of the invention.
