Definitions

  • the present invention relates to a nailing plate connector of the kind defined in the preamble of Claim 1.
  • Structural engineering has steadily progressed towards greater precision with regard to measurements in building constructions and towards the prefabrication of structural elements/modules of precise dimensions which, in order to achieve the desired precision in the overall measurements of the construction, must be interconnected without play or tolerances therebetween, .
  • nailing plate connectors i.e. plates which include a relatively large number of nail accommodating holes that are divided into two groups, such as to enable the plate connector to be nailed to two different elements that are to be connected by means of the nailing plate.
  • nailing plates in the form, e.g., of a metal plate element that is bent to an angle of 90° so as to enable a beam having a first longitudinal direction to be nailed to the end of a beam that extends in a direction perpendicular to said first direction, for instance.
  • a long-standing problem with such nailing plate connectors is that they solely allow the sub-elements to be affixed in relation to one another in the mutual positions occupied by the sub-elements when the nails have been driven into respective groups of holes in the nailing plate connector.
  • an object of the invention is to provide a nailing plate connector that will enable two structural elements to be joined stably together and which will also enable these elements to be drawn forcibly together to provide a rigid join therebetween, or to be moved forcibly apart in a controlled manner, so as to enable the requisite, prescribed measurement accuracy to be established before the structural elements are finally secured in their relative positions with the aid of the nailing plate connector.
  • At least one of the two slots in the nailing plate connector has a widening on one long edge, for defining a nail latching position along the slot.
  • one or both slots may include several widenings which are mutually spaced in the long direction of respective slots. The widenings may conveniently be provided on the mutually distal edges of the slots at their converging end- parts, and on the mutually proximal edges of the slots at the diverging ends thereof.
  • the slots need not be rectilinear, but may have a chosen curvature.
  • the angle at which the slots are inclined relative to the movement direction of the nailing plate will preferably be such that the connector will normally be unable to bend a nail in normal use.
  • the slots are dimensioned so that the distance through which the slot can move or displace a nail will correspond approximately to the distance through which the nail can be moved by elastic deformation or during deformation of surrounding wood material.
  • the slots may define an angle of about 10° to the direction of movement of the plate connector, this direction of movement normally coincides with a symmetry line to both of the slots in the nailing plate connector, when the plate connector is comprised fundamentally of a flat plate.
  • the nailing plate connector When the nailing plate connector has the form of a plate that is bent to an angle of 90°, one slot will extend parallel with the bending line. This one slot is then nailed to a beam or like structural element with which a beam-end shall be rigidly connected, with the aid of the other slot, said other slot being positioned obliquely to the bending line so as to enable a beam-end to be drawn forcibly into rigid abutment by displacing the nailing plate connector.
  • the nailing plate connector may conveniently include one or more "striking" shoulders for facilitating movement, or displacement, of the plate connector in a desired direction, e.g. in the general direction of the bisector of the two slots, with the aid of a hammer or corresponding tool.
  • the nailing plate connector may be used to join two beam-ends coaxially together in the following way.
  • the two beam-ends are placed adjacent one another and a nailing plate connector then placed on each major beam surface in the region of the join.
  • a nail is then driven into each slot in respective connectors, preferably in the region between the ends of the slots, said nails being driven in until the nail heads are spaced slightly from the plate connector lying against the beam.
  • the nailing plate connector is then knocked in a direction along the bisector of the slots, such that the slot edges coact with the nails, which, in turn, dog the structural elements in a direction transversely to the longitudinal direction of the slots, for instance such as to draw the beam-ends into abutment with one another and therewith form a rigid join.
  • the nailing plate connector can then be secured in the position into which it has been moved, by driving nails into some of the other holes in the connector. These holes may have a size corresponding to the diameter of the nail. Naturally, the nails that extend through the slots may also be hammered home so that their respective heads will lie against the edge surfaces of respective slots.
  • the longitudinal edges of the slots may include recesses, for instance sawtooth-like recesses, that will enable the slots to be moved in one direction along a nail while preventing movement of the plate connector in the opposite direction relative to the nail, or while making such movement difficult to achieve. This ensures that the nailing plate connector will not slide back under its own violation before it has been fixed in position subsequent to having been moved.
  • Fig. 1 is a schematic illustration of a butt joint between two beam-ends, established with the aid of a nailing plate connector.
  • Fig. 2 is a side view taken on the line II-II in Fig. 1.
  • Fig. 3 illustrates a first embodiment of the slots in the nailing plate connector.
  • Fig. 4 illustrates an alternative embodiment of the slots in the nailing plate connector.
  • Fig. 5 illustrates schematically a joist or lintel joint between beams, achieved with the aid of an inventive nailing plate connector.
  • Fig. 6 is a sectioned view taken on the line VI-VI in Fig. 5.
  • Fig. 7 is a sectioned view taken on the line VII-VII in Fig. 5.
  • Figs. 1 and 2 illustrate a butt joint between the ends of two beams 1, 2 that has been established with the aid of an inventive nailing plate connector.
  • the nailing plate connector includes a flat plate which is provided with two sets of holes 6, 7 and 5, 8 respectively by means of which plate parts 40, 41 can be affixed to respective beams 1, 2.
  • the holes comprise typical nail holes having a size corresponding to the cross-sectional area of an anchor nail.
  • the plate connector 4 also includes two slots 7, 8 which define an angle ⁇ with the bisector 9 of the longitudinal axes of the two slots 7, 8.
  • the angle ⁇ may be about 10°.
  • the bisector 9 is orientated at roughly 90° to the desired relative displacement between the beams 1 , 2.
  • nails can thus first be knocked into the midway region of respective slots 7, 8, although without the nail heads engaging the mail surface of the nailing plate connector.
  • the plate connector can now be knocked in the direction 10 with the aid of a hammer, for instance.
  • the edge parts of the rectangular nailing plate connector 5 may be bent to form edge flanges 42, 43 such as to provide "striking" shoulders.
  • the ends of the beams 1, 2 will be brought together in the directions of arrows 11, so as to provide a rigid, butt joint for instance.
  • Further anchor nails can now be driven through the nail holes 5 and 6 respectively, such as to secure the plate 4.
  • the nails in the slots 7 and 8 can now also be driven home. A desired number of anchor nails can now be driven through the holes 6, 7 in the nailing plate connector 4.
  • the mutually distal edges of the converging parts of the slots 7, 8 include widenings 72, 82.
  • the divergent ends of the slots 7, 8 may also include on their mutually opposing surfaces widenings 71, 81 for coaction with a nail stem to prevent unintentional movement of the nailing plate connector 4 subsequent to having moved said connector in the direction 10.
  • these widenings may have the form of sawtooth formations that will facilitate relative movement of the nails towards respective ends of the slots from a central starting position therein.
  • the slots 7, 8 can be made by giving the slots 7, 8 a length and an angle of inclination which will ensure that the relative displacement of a nail will not exceed a predetermined value.
  • the slots 7, 8 have a length of about 5 cm and an inclination ⁇ of about 10°.
  • Fig. 5 illustrates an inventive nailing plate connector in the form of a plate element that has been bent to an angle of 90°.
  • the bending line can be said to coincide with the symmetry line 9 of the plate connector shown in Fig. 2, although another significant difference is that the slot 8 has a longitudinal direction which is parallel with the bending line.
  • the beam-end 1 can be caused to move into abutment with the side surface of the beam 3, without lateral displacement of the beam 1 along the beam 3.
