CI 108/161, 108/51, 108/56 7 form mounted on a Substructure said Substructure Int. p i i g a of vertical hollow i each 0 Search 56, unit comprising a rectangular Sheet of substantially 52/615 rigid material scored along longitudinal lines into rectangular sections and folded and joined to form a box [56] References Cited tube unit UNITED STATES PATENTS 3,664,906 5/1972 Hartig 52/615 X 17 Claims, 10 Drawing Figures z 7 Z0 Z4 0 l/ J/ I LOAD BEARING STRUCTURE This invention relates to a load bearing structure having a horizontal platform for the load and a substructure between said platform and the ground or floor.
  • the main object of the invention is to provide a structure which can be produced cheaply and quickly, primarily for use in theatres and exhibitions and which are easily transportable.
  • a further object is to provide a structure which when not in use, can be stored conveniently in a small space and which can be set up for use easily.
  • Another object is to provide a construction in which the sub-structure can take various forms and built to different heights using standard units.
  • a load bearing assembly comprising a horizontal platform mounted on a sub-structure said sub-structure consisting of a plurality of vertical hollow units, each unit comprising a rectangular sheet of substantially rigid material scored along longitudinal lines into rectangular sections and folded and joined to form a box tube unit.
  • the units used can be of identical form, or units of different form can be built up as a super-structure.
  • the adjacent sides of units can be secured together either temporarily or permanently, or a means such as a lattice structure, can be used to hold the units together.
  • each unit consists of a rectangular sheet divided by score lines into three main sections of identical width and extending therefrom, three further sections also divided by score lines, two of which are identical and constitute strips for the joining together of the blank, the three sections of identical width being folded in the same direction relatively through 90 and the other three folded through angles such that the vertical edge of the end section thereof abuts the score line between the first and second of the three identical sections.
  • each unit consists of a rectangular sheet divided by score lines into four main sections of identical width and three further sections also divided by score lines, two of which are of the same width and joined by a wider section, said two serving as fastening strips for the joining together of the unit, the first four folding sections being folded in the same direction to form a square box structure and the three further sections folded in a substantially Z-shaped manner, the two of the same width being secured to adjacent surfaces of the box forming sections.
  • Each unit may also consist of a rectangular sheet having three sections divided by score lines and folded in Z-shaped manner, the end sections being of identical width and the median section wider than said end sections.
  • each unit consists of a rectangular sheet having four main sections divided by score lines and of identical width and, three further sections divided by score lines and extending from one edge of an end main section, the end sections of the further sections being of identical width, the four main sections being folded in the same direction to form a square box structure with the one further section adjacent the one main section secured thereto, the intermediate section extending obliquely from the one main section towards its adjacent main section with the other end section secured to said adjacent main section.
  • the load distributing surface of the load bearing structure in accordance with the invention is preferably a wooden plate or board which is placed, in the simplest case, on to the folding units.
  • the structure of the invention thus consists of constructional elements or units which are supplied or stored flat and which are made from blanks or sheets preferably from corrugated cardboard and which, after folding up along the scored or fold lines on the blank and after fixing together or insertion, are given their stability and, form the desired configuration of the substructure.
  • the connecting of the individual units can be by stitching, by staples, by adhesives, by adhesive strips or the like.
  • the load distributing surface needs to be placed on assembled units. If however, on the contrary, bevelled or stepped plane load bearing structure is used, then the surface board can be fixed.
  • the provision of theatre, film exhibition and similar structures is considerably simplified, since plane load bearing structures can be used which can be assembled on the site by simple means from industrially finished constructional units.
  • the units i.e., the sheets, can be standardized for economic reasons. They can be identified by different colouring according to their intended use and can be delivered and stored in stacks. After the joining together of the units their outer sides or visible surfaces can be painted, pasted on or clad with any desired material in accordance with the intended effect. After the termination of use, the units can be discarded. Thus, not only is the erection and structural alteration of the structures simplified, but also the demolition thereof. More especially storage space is economized.

  • the folding section 105 is folded outwardly and forms a fastening strip.
  • the rectangular blanks in stacks with fold lines have to be folded along these lines and be secured together, as is shown in FIGS. 4 and 5 to form a folding structure, e.g., 40.
