Definitions

  • the invention relates to constructional elements of the kind comprising two plates of nailable material and at least one web which keeps the plates in spaced parallel positions.
  • the material of the plates may be solid wood, for example sawed boards, or plywood, chipboard, wood fibre board or the like.
  • Elements of the said kind may be made with one, two or more webs and also be of various design in other respects, for example as l-, H- or box beams or as larger elements adapted for various purposes.
  • the force required for pressing a peg or tooth into wood or similar material will be the sum of the force causing the tooth to cut through the wood fibres, and
  • teeth may conveniently be formed with at least two points so as to permit the use of larger and stiffer teeth with consequent increased pull-out force and shear resistance.
  • it may also be convenient to form web sheet and tooth with at least two sharp bends in alternate directions, so as to provide a separate local stiffening for each point.
  • the web sheets may be arranged in many different ways,
  • FIG. 2 is a perspective view on a larger scale showing part of a web sheet capable of forming part of the element in FIG. 1,
  • FIGS. 8 and 9 are sectional views taken along the lines 88 and 99, respectively, in FIG. 7,
  • FIGS. 12 and 13 are end views showing portions of two web sheets made from the blank in FIG. 11,
  • FIG. 16 is a sectional view taken along line 1616 of FIG. 17 showing ajointing sheet adapted to be used for the forcetransmitting connection of two pairs of plate sections forming part ofa constructional element according to the invention
  • FIG. 17 is a sectional view taken along line 17-17 of FIG. 16,
  • FIG. 18 is a detail view in horizontal section along the line l8l8 of FIG. 19 of part of a constructional element according to the invention in the form ofa closed box element with facilities for connecting elements placed side by side, and
  • FIG. 19 is an elevational view of the same.
  • the tooth shape shown in FIG. 5 may be convenient when the tooth is to penetrate through a relatively thin plate and it is at the same time desired to have a certain width at the base of the tooth with a view to high shear resistance.
  • the structure 120 is a so-called two-way element, i.e. an element having a considerable transverse dimension and stiffened in both longitudinal and transverse planes, and for this purpose the individual sections of which the web sheets 124 are composed have to be interconnected for transmitting vertical forces (shearing forces). This will for example be the case at the intersection I26 in FIG. 10.
  • the common axis 110 which extends at right angles to the longitudinal direction of the sheet, will after a shaping into Wform as shown in FIG. 12 form a continuous fold line 110 forming the central axis of the tooth section and extending straight through the web sheet and into the opposite tooth.
  • W- formed sectional shape will in addition to permitting-a greater tooth width afford a better torsional stability than a V-shape since the shear center of the tooth cross-section will be located at or near the center of gravity.
  • FIG. 15 may be formed in a blank as shown in FIG. 14.
  • the sheet has aligned plane portions separated by sharp inward bends formed symmetrically with respect to transverse planes through the respective central lines 140 of the teeth.
  • This shape is particularly suited for the outer web sheets in an element as shown in FIG. 18, since in that case there is obtained a maximum overall aligned sheet area affording increased freedom in attaching connecting fittings and less problems with sealing and insulation between adjacent and constructional elements.
  • FIGS. 16 and 17 show the manner of using a wave shaped metal sheet 161 with large teeth 162 and 162 for providing a force-transmitting connection of two sections of aplate member.
  • poywood is used as the plates it will be necessary in large elements to make up the plates by jointing individual plates of suitable standard sizes.
  • the joint must be capable of resisting the pressure and shear forces in the plane of the plate which are caused by the bending stresses to which the element is subjected, and in most cases it is then necessary to resort to a glued bevel joint or a blunt joint with a jointing strip glued or-nailed to the inner face.
  • These jointing methods are both timeconsuming and therefore expensive, and especially the glued bevel joint requires expensive special equipment.
  • FIG. 18 and 19 there is shown a portion of an entirely closed box-shaped element, in which sheets of the type shown in FIG. are used for the webs. These extend entirely around the element and are closed at the joint by a seam 187.
  • An element of this form may be made entirely water-tight by using such a high pressure for the assembling that even the base portions of the web sheets are pressed somewhat into the plate members. This may be of considerable advantage by preventing water from penetrating into the element during the time of construction and causing consequent moisturc problems, for example risk of damage on the insulation.
  • fittings 183 in the form of folded metal plates formed with a plane portion 188 preferably flush with the outer edges of the plate members.
  • this portion 188 there is formed a rectangular hole 185 and a corresponding tongue-shaped portion 184 capable of being bent outwardly about a line 190 so as to project at right angles to the plate 188.
  • the tongue-shaped portion 184 of one element can be passed into the hole 185 of the adjacent element and vice versa, and the two elements will thereby be locked together so as to be prevented from relative motions in the vertical direction, or in other words, there will be achieved a locking effect similar to that ofa groove and feather connection.
  • the fitting 183 may have additional holes 186 punched therein for attachment to a supporting base by hook bolts or the like and for attaching posts by means of flat steel strips.
  • a construction element comprising two parallel plates of nailable material and at least one web element disposed between and perpendicular to said plates for interconnecting said plates in spaced apart relationship, said web element comprising an elongated sinuous metal sheet having a plurality of spaced teeth lying in the same plane as said sheet and extending outwardly of opposite side edges thereof, said teeth along one of said edges being in transverse alignment with the teeth along the other of said edges, said sheet having transverse, parallel and spaced sharp bends extending throughout its width and into said teeth, each said teeth having at least two sharp reverse bends extending likewise through the width of said sheet thereby forming teeth of Z-shaped cross-section.
  • each of said teeth have three sharp reverse bends extending likewise throughout the width of said sheet thereby forming teeth of W-shaped cross-section.
