Device for positioning and fixing beams with floor anchors

The invention relates to a device for positioning and fixing beams with floor dowels.

When setting up and positioning beams or similar, for example when erecting beam foundations for garden houses or pavilions, in addition to the necessary horizontal or vertical alignment, there is always the problem of positioning the beam or beams used in their respective position and also fixing them in this position. Fastening devices that can be anchored in the ground and which support the beam at their upper free end are usually used to fix them to the ground. The beam is fixed to the fastening device after the fastening device has been anchored in the ground, usually by directly screwing, nailing or similar the attached beam to the upper free end of the fastening device. The direct fixation to the ground anchor has the disadvantage when putting on or taking off the beam and when aligning it precisely that all fixing connections have to be set very precisely, which is laborious and time-consuming.

In practice, ground anchors that can be screwed into the ground like a corkscrew and onto which the beam is fixed directly have proven to be effective; however, in principle, anchoring devices that can be cast in concrete or hammered in can also be used.

If a beam is to be fixed in the ground in a desired position using several of these ground anchors, it is necessary that the ground anchors are aligned exactly at the desired height and in the desired position when anchored in the ground. Otherwise, the beam as a whole cannot be fixed in the previously determined position due to the positioning of the fixing elements already determined before the ground anchors are screwed into the beam due to any position deviation of the individual ground anchors. During the screwing-in process, the position of each individual ground anchor must therefore be checked again and again and any deviation, e.g. due to stones in the ground or similar, must be corrected to ensure that the beam is fixed in the specified position. Even a small deviation in the position of a ground anchor can only be corrected by changing the positioning of the corresponding ground anchor. However, this can lead to the ground anchors becoming loose in the ground.

Additional movable positioning devices as an insert between the beam and the floor anchor are known as state of the art, but their construction is complex and expensive; moreover, even when using these devices, positioning must be carried out individually on each floor anchor.

From WO 97/08409 of the same applicant, a device for vertically arranging a pole or post-shaped object is known. The pole or post-shaped object is provided with a receiving bore, which

can be placed on a retaining pin of a floor-side fastening device, in particular a floor anchor, and thus fixed. The retaining pin can be pressed into the object. The axial play between the retaining pin and the receiving hole enables the object to be positioned vertically and, in principle, horizontally.

The device of WO 97/08409 has proven itself in practice; however, it has the disadvantage that, on the one hand, the base-side fastening devices require specially formed retaining pins and, on the other hand, the pole- or post-shaped objects must be provided with corresponding receiving holes. This limits the flexibility in the use of the device due to the necessary preparatory work on the objects to be fixed and means additional costs, especially since base-side fastening devices with a standardized receiving section cannot be used.

The object of the present invention is to provide an inexpensive and simple device for positioning and fixing beams, which allows positional deviations of the floor dowels within certain limits and yet enables exact positioning without preparatory work and with little positioning effort on the individual floor dowels.

This object is achieved according to the invention by a device having the features according to claim 1.

Appropriate further training is defined in the respective dependent claims.

By having a base plate of the floor dowel insert with a holding means attached to it, the device according to the invention for positioning and fixing beams has the advantage, in contrast to the prior art, that the position of the beam is fixed in a simple manner, in that after it has been pressed in, the holding means attached to the base plate of the floor dowel insert at least adheres to the beam. No complicated and therefore expensive conventional positioning devices are required to correct deviations of the set floor dowel from the exact desired position.

When positioning the beam on several floor dowels, for example when aligning a beam foundation, the problem of all floor dowels having to be positioned precisely individually does not arise by pressing the beam onto the retaining means of the respective base plates of all floor dowel insert parts. The exact position of the beam is therefore securely fixed by the retaining means of the floor dowel insert parts that adhere to the beam or are connected to the beam and are positioned in the holding sections of the floor dowels.

The arrangement of the holding means on a base plate of a floor dowel insert part that can be received in a standardized holding section of a floor dowel increases the flexibility of the use of the floor dowels and reduces their production costs, since no floor dowels with special holding devices for holding beams are required.

In a preferred embodiment of the invention, the holding means consists of at least one positioning mandrel, which, by pressing the beam,

The floor dowel insert part connects to the beam in a fixed position according to the desired position of the beam and thereby at least fixes it in place. This allows the positioning of the beam to be determined particularly safely and quickly simply by pressing it on. The mandrel-like design also means that no preparatory work on the beam is necessary, which increases the flexibility and application possibilities of the device.

The positioning mandrel can be arranged as a single molded part, particularly centrally on the base plate. However, several positioning mandrels can also be arranged on the base plate.

A particularly preferred embodiment is one in which at least two sections of the base plate itself are bent out of the base plate as positioning mandrels. The position and shape of these sections can be determined, for example, by punching or cutting out, preferably at two corner or edge areas of the base plate. These are preferably two diagonally opposite corner areas. In addition to punching out the shape and bending it out, it may be useful to rework the positioning mandrels obtained in this way, for example by deburring or grinding.

This design results in a reduction in manufacturing costs, since no special molded part has to be arranged on the base plate as a positioning pin. In general, particularly secure positioning is achieved by using several, at least two, positioning pins.

According to a further embodiment of the invention, the holding means is designed as an adhesive surface, which by pressing the bar,

The floor dowel insert part is fixed to the beam in a fixed position, at least by adhesive, in accordance with the desired position of the beam. This makes positioning particularly easy and even faster. The necessary pressing forces can be reduced. In addition, it is possible to not only fix the positioning by adhesive, but also to fix the floor dowel insert part to the beam by gluing. This enables a particularly quick and labor-saving procedure by positioning and fixing at the same time, without having to remove the beam to fix it.

In an advantageous embodiment, the base plate can be provided with at least one opening for receiving fastening elements for fixing the beam to the floor dowel insert part for particularly secure fixing of the floor dowel insert part to the beam.

The openings can essentially be arranged in a square pattern at the edge areas of the base plate to enable particularly secure fixing.

However, other arrangements with a central opening in the base plate are also possible. Furthermore, two further openings can preferably be provided at the edge areas, which further increases the security of the fixation and at the same time provides greater flexibility, for example when fixing beams with a relatively small cross-section.

Advantageously, the floor anchor insert part is received with a shaft-like section in the holding section of the floor anchor so that it is fixed there and securely positioned in the holding section.

The shaft-like portion is preferably cylindrically shaped with an outer diameter that essentially corresponds to the inner diameter of the holding portion of the ground anchor, so that the axially position-fixing reception of the shaft-like portion in the holding portion of the ground anchor is particularly secure.

The shaft-like section can preferably also be shaped in such a way that the outer diameter of the cylindrical section is substantially smaller than the inner diameter of the holding section of the floor dowel and the shaft-like section widens at its free end in the shape of a collar essentially up to the inner diameter of the holding section. As a result, the shaft-like section is axially fixed in position when inserted into the holding section of the floor dowel by the collar-like diameter extension. On the other hand, the shaft-like section also serves to be held in the holding section in a tilted position due to its smaller outer diameter. This offers additional flexibility, particularly when aligning and positioning beams vertically but also horizontally, while largely maintaining the axial position fixation of the floor dowel insert part in the holding section of the floor dowel.

It is particularly advantageous to fix the shaft-like section of the floor dowel insert in the holding section of the floor dowel by means of a clamping screw, as this enables a particularly secure and firm fixation of the beam and the floor dowel insert attached to it to the floor dowel.

The invention is explained in more detail below using an exemplary embodiment with reference to the accompanying drawings.

inventive device for positioning and fixing beams.

Fig. 1 shows a preferred embodiment of the device according to the invention for positioning and fixing beams.

The device shown positions and fixes a beam 1 and consists of a ground anchor 2 screwed into the ground with a standardized

Holding section 3 for axially fixing the position of a substantially cylindrical shaft 9 of a floor dowel insert part 4. The floor dowel insert part 4 has a base plate 5 with a holding means shaped as a positioning mandrel 6 for determining the position of the beam 1 and openings 7 for receiving fastening elements, in particular screws or nails, for fixing to the beam 1. The shaft 9 of the floor dowel insert part 4 can be fixed in a holding section 3 of the floor dowel 2 with a clamping screw 8.

After placing the floor dowel 2 in the desired location, it is adjusted to the desired height by screwing it in or out as appropriate. This state is shown in Fig. 1, so that the upper edge of the holding section 3 already has the desired height. Now, as indicated by the arrow between the floor dowel insert part 4 and the floor dowel 2, the floor dowel insert part 4 is inserted with its shaft 9 into the holding section 3 of the floor dowel 2. The base plate 5 is preferably designed in such a way that it forms a stop for the shaft 9 on the holding section 3. In general, it is not the upper edge of the holding section 3, but the base plate 5 with the holding means that forms the reference surface or the reference point for the exact height adjustment.

In the next step, the beam is pressed into the desired position and orientation on the positioning mandrel 6, as indicated by the second arrow between the beam 1 and the floor dowel insert part 4. This presses the positioning mandrel 6 into the beam 1. The beam 1 then ideally rests against the base plate 5 at least at one point. The pressed-on positioning mandrel 6 determines the positioning of the beam 1 relative to the floor dowel insert part 4. By pressing in the positioning mandrel 6, the floor dowel insert part 4 is also at least adhesively fixed to the pressed-on beam 1 and detachably connected to it.

However, it is possible that further conventional positioning and/or leveling devices are present between the floor dowel insert part 4 and the holding section 3 of the floor dowel 2 or at another suitable location in order to enable additional adjustment of the positioning. However, this is purely optional and does not restrict the advantageous procedure and function according to the invention in any way.

Now the beam 1 can be removed again. Then the floor dowel insert part 4 is preferably screwed to the beam 1 using screws through the openings 7 (at least one, preferably three to four) in the base plate 5 in accordance with the positioning determined in the previous step.

The beam 1 with the floor dowel insert part 4 fixed to it is now placed back on the floor dowel 2. If a further, firmer fixation is required, the shaft 9 of the floor dowel insert part 4 inserted into the holding section 3 can be fixed using the clamping screw 8.

Fig. 2 shows a partial sectional view of the preferred embodiment of the floor anchor insert part 4 of the invention.

Shown is the floor dowel insert part 4 provided with the positioning mandrel 6, which rests essentially flat on the beam 1 with the base plate 5 and is fixed to the beam 1 with screws through the openings 7 in the base plate 5.

It is also possible for the base plate 5 to have an adhesive surface instead of or in addition to the positioning mandrel 6. It is then possible that the adhesive effect when the beam is pressed onto the holding means not only fixes the floor dowel insert part 4 to the beam 1 to determine the positioning, but also that the permanent fixation that would otherwise be achieved by means of screws is already carried out by gluing in the pressing step. Additional screwing or nailing is of course possible if the beam material is suitable and if the openings 7 are present.

Fig. 3a and Fig. 3b show an application example of the preferred device according to the invention when positioning and aligning a beam 1, as is used, for example, when erecting a beam foundation for garden houses.

The beam 1 is aligned in its vertical position with three ground dowels according to the procedure described in connection with Fig. 1 and Fig. 2. Fig. 3 a shows the arrangement of the ground dowel insert parts 4 pressed on and fixed with screws through the openings 7 to the beam 1 according to the exact position of the beam 1. The ground dowel insert parts are not in line because the positioning of the ground dowels 2 deviates from the exact desired positioning when screwed in at the desired locations, for example due to stones in the ground. The offset arrangement of the pressed ground dowel insert parts 4 compensates for these position deviations, the beam 1 is precisely aligned and positioned.

Li Fig. 3b is the beam 1 from Fig. 3 a with the essentially cylindrical shafts 9 of the floor dowel inserts 4 fixed to the beam 1 in the

The floor dowels 2 are inserted into the holding sections 3 and fixed in place with the clamping screws 8. The horizontal alignment is achieved by screwing the individual floor dowels in or out accordingly. Due to the fixation of the floor dowel insert parts 4 by clamping the shafts 9, the height of the individual floor dowels 2 can be easily adjusted at any time by loosening the corresponding clamping screw 8, without the corresponding fixation on the beam 1 itself having to be loosened in the conventional way.

Fig. 4 shows the holding section 3 of a ground anchor screwed into the ground at an angle with an inserted ground anchor insert part 4 according to a further embodiment of the invention. The ground anchor insert part has two positioning domes 6 bent out of the base plate 5, which are punched out at corner or edge areas of the base plate 5 and then bent out of the base plate plane. The openings 7 for receiving the fastening means are arranged diagonally opposite one another, with one of the openings 7 in the middle of the base plate 5. The base plate 5 is aligned vertically. This is achieved by tilting the insertion of the shaft-shaped section 9 of the ground anchor insert part 4 into the holding section 3 of the ground anchor. The secure axial positioning of the shaft-shaped section 9 is achieved by the collar-shaped extension at its free end, which has essentially the same diameter as the interior of the holding section 3. The floor dowel insert part 4 can be securely fixed in the holding section 3 by clamping the shaft-shaped section 9 using the clamping screw 8. The process of positioning the beam is carried out in the manner already described above.
