Definitions

  • the invention relates to a wooden support of the type specified in the preamble of claim 1.
  • Such wooden beams are used in particular in the form of lattice girders on a large scale as formwork girders and here again in particular in connection with formwork elements which consist of large-area formwork panels which are supported on the back by several parallel steel belts, on which a plurality of wooden lattice girders are anchored parallel to one another which give the formwork panel the required rigidity.
  • formwork elements consist of large-area formwork panels which are supported on the back by several parallel steel belts, on which a plurality of wooden lattice girders are anchored parallel to one another which give the formwork panel the required rigidity.
  • These large-area formwork elements are very popular due to their light weight, nailability and the possibility of easy cleaning. Problems arise because of the need to have panels of different sizes available.
  • the invention is therefore based on the object To create wooden girders that can be arbitrarily stacked in an unkinked longitudinal axis of the girder and enable the manufacture of formwork elements of different heights.
  • the profile adapters can each be made over a beam width be led that small lateral displacements of the carrier, which can occur in the formwork operation, can be included.
  • the adapters can engage on cross members that are supported on the back of the full-strength webs. Instead, the tendons can also be anchored in recesses in the full-wall webs using suitable abutments.
  • the wooden girder is designed in particular as a lattice girder, the belt struts in pairs resulting in a knot division and the half knot division corresponding to a grid which forms a unit length from which girders with lengths can be produced which have integer multiples of these field lengths.
  • extension elements are further provided which can be placed and braced on a carrier end instead of extension carriers, the length of such an extension element corresponding in height to a carrier being equal to a field length.
  • the wooden girder is designed as a lattice girder with an upper chord 10, lower chord 12 and struts 14 which are glued into grooves in the upper and lower chord.
  • too Solid wall girders are used, which are provided with corresponding recesses for the tendons.
  • the lattice girder is designed as a grid girder, ie the fields formed by the inclined webs have a length in the longitudinal direction of the girder of 32 cm with a girder height of 36 cm and a belt width of approx. 10 cm.
  • the last field at the two ends of the carrier has a full wall web 16 which, as can be seen from FIGS.
  • This full wall web 16 is galvanized with an upper wedge - And connected to the lower belt, it can also have the same width as the belts. It can consist of two or more pieces of solid wood or be glued to boards. According to the exemplary embodiment according to FIG. 5, a space can be left between two web sections if, for example, solid wood pieces with standard sizes with a cross section of 7 x 14 cm are used (this center distance then results from the selected grid division).
  • a fitting recess 18 is provided on the end face in the full wall web 16, which is triangular in the embodiment according to FIG. 1, semicircular in the embodiment according to FIG. 2 and in the embodiment according to FIG. 5 by a recess of the entire full wall web.
  • Profile fitting pieces 20 are inserted into the fitting recesses of two wooden beams abutting one another on the end face, which serve to transmit the lateral force.
  • the preferred embodiment of the profile fitting 20 can be seen in FIG. 10. This training is used in carriers according to FIGS. 1 to 2, 7 to 8, 9 and 14.
  • This Profilpledge choir 20 consists of a square in cross-section tube 22 are welded to the ends of tabs 24 with which the fitting pieces as shown in FIG. 9 can be seen, by means of nails at the full wall web 16 of the end face auffact now- t s carrier can be fastened.
  • the profile fitting piece 20a consists of a tubular section 26 of circular cross section, which fits into semi-circular profile recesses 18 according to FIG. 3.
  • the profile adapter 20b which can be used in the support eye formation according to FIG. 5, can be seen from FIGS. 12, 13 and 13.
  • the profile fitting piece is designed as a multi-layer fitting plate, the height of which corresponds to the web height and the width of which is somewhat larger than the width of the belts (FIG.
  • the full-wall web 16 of the end reinforcement protrude on one side of the carrier by the amount of the fitting recess at the other end of the carrier, but this has the disadvantage that the carriers can only be increased in a certain orientation.
  • Clamping means are provided for stocking up the supports, which brace the stocked up supports against one another at the end.
  • U-shaped bars 28 are supported on the rear side of the solid wall web 16 forming the final reinforcement.
  • a spindle 30 Adjacent to the longitudinal axis of the girder, a spindle 30 is guided through holes in these profile irons 28, which, by means of spindle nuts 32, causes two U-profile irons 28 to be braced, which in the normal case are in each case on the full-wall webs of two adjacent wooden lattice girders are supported, the spindle 30 being located in the middle between these supports.
  • profile fittings which absorb the transverse force are made from metallic pipe pieces in accordance with the exemplary embodiment according to FIGS. 10 and 11. Instead, appropriately machined wooden profile fittings could be used.
  • an extension element 34 is clamped onto the end of a wooden lattice girder in the manner shown in FIGS. 7 to 9.
  • Such an extension element 34 which has the length of a grid (for example 32 cm), is used when the height by which the support is to be added does not justify the use of a second lattice support.
  • a grid for example 32 cm
  • any heights can be detected, which is particularly useful when formwork is used for buildings that have very different storey heights.
  • the extension elements 34 are designed as solid wall girders with the corresponding length, the width of these elements corresponding to the belt width.
  • the clamping profile iron 28 is not required.
  • the full-wall web 16 forming the end reinforcement has a central circular opening 36, and a bore 38 leads into this opening in the longitudinal axis of the beam, which passes through the full-wall web 16 in the middle and continues in the profile fitting 20b.
  • a spindle 42 is guided, on which a pressure shell 44 designed as a casting is placed within the opening 36, which can be seen in detail in FIG. 16 and which with its cylindrical wall is the wall of the opening 36 fits snugly.
  • a wedge 46 which is driven into a slot in the spindle or the tension rod 42, is supported on the back of the pressure shell in order to ensure bracing.
  • a wing nut could also be screwed onto the tendon designed as spindle 42.
  • the extension element 34 is provided at the rear end with a recess 35 into which the here as a double-U profile trained crossbar 28 stands so that this crossbar does not protrude over the length of the formwork beam or the formwork element.
  • lattice girders are used, in which double webs 16a set back towards the ends are arranged, between which a gap 48 remains.
  • the fitting 20c shown in FIG. 19 consists of a T-shaped metal plate 50 which carries fitting shells 54 welded onto the ends 52 of its transverse leg, which fit the upper or lower flange 10 or 12 and the end face of the double webs 16a and thus the Ensure shear force transmission.
  • the vertical leg 56 of the T-plate 50 which converges towards the lower end, carries reinforcing plates 58 and thus fits into the gap 48 between the double struts 16a.
