Definitions

  • a new design of a beam web for a beam including attachment of a web member to a flange of a beam.
  • the beam web member consists of rod, wire, pipe or strip type material and bent into a zigzag like fashion.
  • This invention is an extension of patents SE 466 860 and SE 466 861, the first patent in ⁇ volving a building element consisting of a slab with stiffening beams incorporating a web member and flange, several similiar to those described in the claims of this patent applica ⁇ tion, and the latter involving the configuration of attachment holes for the beam web, this is also described in the claims.
  • diagonal braces In a beam or beam element or slab with a stiffening beam, with flanges and web members that form diagonal braces in a lattice girder in a zigzag configuration, the diagonal braces will be alternatively tensioned and compressed when subjected to load.
  • Present day techno ⁇ logy exclusively utilizes plane bent web members. The attachment points in the flange are subjected to a twisting effect, as seen from the side.
  • the bends of the web member are attached by means of a cast compound, moulded into oblong holes carved out in the longitudinal direction of the flange.
  • the hole is machi ⁇ ned with a milling machine, which accounts for a cylindrical oblong form, with smooth sides, the size of the hole corresponding to the diameter of a rotating cutter.
  • SE B 449 887 shows a beam where the load capacity of the flanges has been increased by a, in a lengthwise stretched track, forming a part of a flange, cast material moulded with the flange.
  • the wire element is attached at or near the bending point.
  • FRAl 2 568 613 shows a beam where the load capacity of the flanges has been increased with a longitudinal rod incorporated in the flange, attached to a zigzag bent web member in ⁇ corporated in a elongated lengthwise track in the flange, accounting for better adhesion and cooperation.
  • the purpose of the track shown in Fig 6 is to provide room for the longitudinal rod of the flange that, in this design, is situated beside the zigzag bent web member.
  • the track is made before assembling the flange, consisting of two parts. This track is also elongated.
  • US A 3 857 218 shows a through hole which is illustrated in Fig 4.
  • an entirely different concept in the fixation of the webrods is presented, including several details that have nothing in common with our application.
  • WO Al 88 / 03209 and 03210 Fig 7 and 8 shows a flange with a hollowed out bottom. It's purpose, as in our invention, is to anchor the bends of the web member in the flange. A crucial difference in this invention is that the track is missing entirely.
  • the track in our invention, has a limited extension in the hole that is neither elongated or through and that is worked in the flange in order to provide room for the embedded bends of the web and to provide better anchorage between the casting compound and the flange.
  • the hole and track can further be worked directly in the flange, consisting of only one piece. This can be achieved in the same working moment with a single tool, not requiring slanting of the tool or flange.
  • the shape of the web member in its simplest form is widely known through the Swedish patent 56 448. This form has only been used as stirrups and ties embedded in concrete struc ⁇ tures and not as a separate beam web in a lattice-type beam. The purpose of the invention and most important characteristics
  • the purpose of this invention is to improve the attachment between the cast material and the flange and, with that, even the attachment of the web member that is especially affected by the twisting actions in the embedded bends, due to the direction of the force of the web member, one compressed and the other tensioned, that attempt to twist apart the attach ⁇ ment between the flange and the casting compound.
  • Suitable material to be used is a straight drawn rod or a wire wound into a large diameter coil, making sure that the straight parts of the web member, that function as diagonal bra- ces in the lattice, are not allowed to be curved.
  • the web member is wound into a spiral around a piece of sheet metal with rounded corners, or two round parallel bars so that a helicoid is obtained.
  • the entire web can be flattend so that the bends are pressed together into loops around the bars.
  • the coiled webs are then pulled apart in the lon ⁇ gitudinal direction, thus creating the intended zigzag pattern forming the diagonal braces in the lattice.
  • the spiral coiled web member is pulled apart into a zigzag shape around long rods before the bends are pinched together in transverse positioned loops. These loops provide good an- chorage between the web member and the casting compound in the flange.
  • the web is formed of two coils, one wound to the right and the other wound to the left, si- miliar to left-handed and right-handed threads.
  • the webs are pulled apart, positioned at a suitable angle to each other, slightly displaced in the longitudinal direction so that they match each other when joined together, similar to when clasping the hands with straight fingers.
  • Another alternative in eliminating the effects of torsional forces described above is to utilize the slabs between the beams where the beams are incorporated in the element, by simply using the beams in pairs In the element so that the two torsional moments elimina- te each other.
  • the bends can also be equipped with double loops to improve anchorage and to ease the pulling apart of the web, since deformation will be slighter.
  • Fig 1 shows a flange with hole and tracks 4 at the ends of the hole.
  • Fig 2 shows a flange with hole and track.
  • Fig 3 shows a flange with hole without track with a plane bent 23 web member.
  • Fig 4 shows a longitudinal view of a beam flange with a transverse bent 24 web member 11, embedded In casting compound.
  • Fig 5 shows a cross section of a beam flange with a web member 11 wound into a helicoid and embedded in casting compound.
  • Fig 6 shows a cross section of a beam flange with poured in flattened web member 11 em- bedded in casting compound.
  • Fig 7 shows a view of a web member 11 consisting of a rod wound into a counter clockwise flat helicoid.
  • Fig 8 shows a view of a web member 11 wound according to Fig 7 after being pulled apart longitudinally.
  • Fig 9 shows a cross section of a web member to a beam consisting of a clockwise wound single rod with bends of various design.
  • Fig 10 shows an elevation of a web member to a beam according to Fig 7.
  • Fig 11A shows a beam with a flange with hole and a pre-cast flange with- a single web mem ⁇ ber 11 in flat spiral according to this invention, in cross section.
  • Fig 11B shows a beam with flanges with holes with a single web member 11 in flat spiral, flattened so that loops are formed at the bends.
  • Fig 11C shows a beam with single web member 11 in flat spiral, further flattened so that loops are formed at the bends.
  • Fig 12 shows a web member 14 bent in a figure eight configuration, as seen in cross section.
  • Fig 13 shows a web member 14 bent in a figure eight configuration as seen in view.
  • Fig 14 shows a web member 16 bent in a continuous half eight configuration, as seen in cross section.
  • Fig 15 shows a web member 16 bent in a continuous half eight configuration attached to a flange 1 and embedded into a flange 2 or a slab, as seen in view.
  • Fig 16 shows a plane view of a beam web element 10, according to this invention, during production.
  • Fig 17 shows in perspective folding of a beam web element 10, during production.

  • Fig 20 shows a beam as seen in cross section with beamweb 11 and with pre-cast flanges 1 and 2.
  • a hole (3) and a groove (4) in flange (1 : 2) consisting of, for example; wood, fiberlike sub ⁇ stance or composite, can be shaped by equipping the rotating cutter with various cutting edges, resulting in a circle-, wave-, triangle-, or parallel trapezoid form.
  • the rotating cutter can be inserted into the flange in the middle of the hole (3), where the turning center is situa ⁇ ted, and then at first fed one way alongside the flange to the groove's first end, and then to- the other end of the groove, thereafter back to the starting position and then drawn out again in the original hole. See Fig 1.
  • FIG. 7 shows a design of a beam web element according to this invention.
  • the beam web assembly (11 ; 12) see Fig 7, 8, 9, 10 and 11, can be made of a rod, wire, pipe or strip type material that is, possibly closely, formed to a flat counter-clockwise (11), see Fig 11A, or clockwise wound (12) helicoid, possibly also flattened, see Fig 11B, then pulled apart, possibly also even further flattened, see Fig 11C so that loops are formed at the bends.
  • a beam web element (14), see Fig 12 and 13 can be formed of a rod closely wound to figure eight configurations, then pulled apart into a zigzag shape, with bends that become somew ⁇ hat transverse, possibly even further flattened.
  • a beam web element (16), see Fig 14 and 15, can be formed from a rod wound around two centers in alternately a one-half-clockwise turn, a half-eight, a one-half-counter clockwise, a half-eight, a half-clockwise turn and so on. It is then densely flattened and pulled apart into a zigzag shape with somewhat transverse bends, possibly also further flattened.
  • This design forms a lattice, as seen in the cross direction of the flange, with two "parallel" rods and with “diagonal braces” in two directions, one leaning to the right and one leaning to the left.
  • This design is referred to in this application under the heading: The purpose of the inven ⁇ tion and most important characteristics, as a "running half-eight".
  • FIG 18 shows a design of a web member element according to this invention.
