Definitions
- the invention relates to a carrier made of wood with sections loaded with transverse tension, which are reinforced by rod-shaped elements arranged essentially transversely to the longitudinal direction thereof.
- rod-shaped elements as a special reinforcement especially in these sections of beams made of wood which are subjected to transverse tension.
- these rod-shaped elements were glued into pre-drilled holes.
- a certain reinforcement of the carrier was achieved transversely to the longitudinal direction thereof, that is to say transversely to the fiber direction.
- the present invention has set itself the task of significantly improving the reinforcement options in the area of sections loaded with transverse tension in a carrier of the type mentioned.
- rod-shaped elements are formed by screws provided with threaded sections at least at their two end regions, which lead over a zone loaded with transverse tension and screwed in from the top or the bottom of the carrier, only via part of the height of the girder and are thus directly assigned to the zone loaded on the transverse pull.
- the invention has practically created the possibility of using a screw for the present purpose, which is sunk correspondingly deeply and is therefore arranged where appropriate transverse tensile forces occur. This has an advantageous effect, particularly with particularly high beams made of wood.
- Such girders can have a height of one or more than one meter, but reinforcement is only necessary at a certain height range of the girder because of the transverse pull that occurs.
- the length of the screws is made smaller than half the height of the carrier. Particularly in the case of beams with a special height, this results in a very substantial saving in material, and, in addition, especially when using screws with threaded sections, the lowest possible forming torque is provided.
- Such screws can be screwed into the wooden support without pre-drilling a hole, and a correspondingly deep sinking is also possible.
- the measure according to the invention can also be used advantageously if two or more screws are aligned approximately parallel to one another at a distance and are screwed in axially, that is to say offset with respect to the height of the support, relative to one another in sections subjected to transverse tension.
- a relatively large section of a girder can thus be provided with a special transverse tensile reinforcement, namely by screwing in a large number of screws, which extend from the upper or the underside of the support are screwed in and screwed in more or less.
- An advantageous embodiment provides that the screws are provided with a thread over the entire length of the shaft. It is thus ensured that the screws can engage in the wood of the carrier over their entire length and thus relatively high transverse tensile forces are able to be transmitted.
- the screws have an inner tool engagement at one end, the diameter of the section of the screws surrounding this inner tool engagement being approximately the same size or only slightly larger than the outer diameter of the thread.
- An advantageous and very simple handling when screwing the screws into the wooden support is when the screws are screwed in with a screwdriver bit, the shaft of which adjoins the area of attack for attachment to the screw or an imaginary envelope cylinder of this shaft has a diameter that is equal to or smaller than the diameter of the section of the screw surrounding the inner tool attack, and has a length for bridging the range of the height of the carrier from the inner tool attack of the screw to the upper or lower limit and further to the screwdriver insert. It can therefore be achieved in a simple manner by using a relatively long screwdriver bit that the screws are screwed in to the desired depth in the wooden support. Without the need for pre-drilling, this creates the possibility of being able to properly position the screw at the appropriate point in relation to the height of the support.
- Figure 1 shows a section of a curved beam made of wood in section, showing various sections loaded on transverse pull.
- FIG. 2 shows an enlarged illustration of a detail from the carrier according to FIG. 1 with the illustration of an opening; 3 shows an enlarged illustration of an end region of a carrier with a notch;
- Fig. 4 to Fig. 8 different designs and areas of beams made of wood, with sections loaded on transverse pull are shown.
- a screw 4 should now be screwed directly into the carrier 1 into the full material.
- These screws 4 to be used here have threaded sections at least at their two end regions. But it is also conceivable to provide a thread over the entire shaft length of the screws 4.
- the length L of the screws 4 in the case of beams 1 of relatively large height H is less than half the height H of the beam 1. For beams of lower height H, this ratio to the length L of the screws 4 can of course also go in the other direction. It can only be stated, for example, that with a beam height H of one meter, a length L of the screws 4 of 20 cm or less is also possible.
- the screws 4 are assigned exactly to the zone loaded on the transverse tension. After the screws 4 have been screwed in from the top 5 or from the bottom 6 of the carrier 1, the screws 4 are screwed in to the extent that they are directly assigned to the zone 2 loaded with transverse pull. It can also be seen from FIGS. 1 to 3 that the screws 4 above and below a zone 2 advantageously protrude approximately the same distance from this zone 2. An optimal introduction of the transverse tensile forces to the regions of the carrier 1 adjoining the respective zones 2 is thus possible.
- the screws 4 have an inner tool grip at one end, the diameter of the section of the screws 4 surrounding the inner tool grip being of the same size or only slightly larger than the outer diameter of the thread. This allows the screws 4 to be screwed in slightly into this relatively far recessed position, especially since the larger "head of the screw means that there is no significant increase in torque when the screws 4 are screwed in. ***"
- the screws 4 can be screwed into this relatively deeply recessed position in a simple manner with a corresponding screwdriver bit, the shaft of which adjoins the area to be attached to the screw or an imaginary envelope cylinder of this shaft has a diameter which is equal to or smaller than the diameter of the portion of the screw 4 surrounding the inner tool attack.
- This screwdriver bit then has a length for bridging the area of the height H of the carrier from the inner tool attack of the screw 4 to the upper or lower limit 5 or 6 of the carrier 1 and further to the screwdriver insert.
- grooves, notches, color markings or the like can be provided on the screwdriver bit.
- Zones 2 loaded in the transverse direction also result in a U-shaped notch in a carrier 1, in order to insert a beam 7 running transversely thereto.
- a zone 2 loaded with transverse tension also results in the area shown here.
