Description

The invention relates to a leveling aid for timber-beam substructures in particular of balcony and patio covers on a substrate according to the preamble of claim 1 and to an arrangement according to claim 15.

It is known, as a leveling aid for timber beam substructures underlay documents in different strengths for balancing and leveling on the pads. The disadvantage here is the complex production of documents, their time-consuming installation and the impact-prone construction.

From the garden catalog "gard compact 2008" of the company Balteschwiler, CH-5080 Laufenburg (see also under www.balteschwiler.ch/pdf/gard08/gard-compact, but also at www.osmo.de), is a "leveling foot Catstep "removable, which is taken from below into the substructure. For this, the substructure, d. H. the beam, pierced vertically and concentric to this hole from below the so-called Ramba bush, which is a threaded nut with a plurality of peripheral axially-facing penetration claws, hammered and the threaded spindle are screwed. The adjustment is made from above with a screwdriver on the upper end side of the threaded spindle, ie through the hole. The disadvantage here is the complex installation with drilling through the beam and the large height structure in basic position. A leveling is only possible in the longitudinal direction and not in the transverse direction, since these leveling aids are each introduced relatively centrally in the beam.

Out DE 20 2008 006 944 U1 are support profiles for rust-like structures, especially for floor coverings and wall coverings made of wood or plastic known. It is a bearing leg and a support leg connected to a central web, wherein the support leg is interrupted with sections arranged in the longitudinal direction.

Out 1 596 039 A2 is a device known as Combined Leveling Device And Anchor Plate For Floor Sleepers. The known device has a fitting in the mounted state on a beam fixed retaining element with an internal thread and a screw-guided in this threaded threaded spindle.

Out EP 1 790 794 A2 is a fixing part for fixing of cover panels on known from US 5,666,769 A is a supporting element known and made EP 1 741 853 A2 is a support for raised floors known.

Based on this prior art, the present invention seeks to provide a leveling aid above genus, which is relatively simple in construction and easy to manufacture and which allows a quick and stable installation, both in arrival and in dismantling, without major, cutting in the beam allows a low height in the normal position and an optimal leveling also in the transverse direction.

This object is achieved by a leveling aid above-mentioned type with the features of claim 1 and an arrangement having the features of claim 15. Advantageous embodiments are characterized in the respective dependent subclaims.

Accordingly, the support member of the leveling is a holding plate, which is designed and fastened with at least one screw on the beam or on the construction that the threaded bushing on a laterally to, or under the wood or beam off or outstanding portion of the retaining plate provided, or is held supported by this. The threaded spindle thus runs laterally outside of the wood. Thus, there is a relatively simple sheet metal part on which the pointing in the vertical direction threaded spindle is arranged so that it outside of the wood, ie outside the corresponding side surface and parallel to this runs. Apart from the fact that a simple assembly by preferably two wood screws is possible, the adjustment can be well visible from the side to and not performed by a poorly visible hole in the beam through. It is thus a faster and stable fixed structure and correspondingly faster degradation possible, only by handling two screws. Apart from the fact that a continuous adjustment is available through the threaded spindles, through which an adjustment or leveling is possible in the longitudinal direction, there is also the additional advantage that the support points are no longer substantially centrally located on the beam, but laterally outside of the beam. As a result, a very stable substructure is obtained, which can accommodate very high tilting moments, since both sides of the substructure, the load-bearing threaded spindles are mounted, so a relatively wide support is available. At the same time a leveling possibility in both the longitudinal and in the transverse direction is possible hereby.

It is advantageous that the retaining plate of a flat against the wood of the substructure adjacent, extending in the longitudinal direction of the wood mounting portion and a cross-section projecting to the supporting portion which carries the threaded bushing. Are then still on the support portion two lateral, perpendicular to this and parallel aligned angle parts present, which are bent upwards (preferably) in a simple and advantageous manner from the sheet metal blank of the retaining plate and designed so that the Winkefteil inner edges in the assembled state as a support abut the longitudinal sides of the beam or Vertikatfläche, then can be a total of the retaining plate of the leveling aid according to the invention in a simple manner from a sheet metal blank and is still sufficiently rigid or despite abragender position can be sufficiently firmly supported on the beam, so that the threaded spindle can maintain its vertical position safe.
The rigidity of the retaining plate, in particular with respect to the laterally projecting support portion can be further increased if a channel-shaped raising or edging is introduced centrally in the transverse direction, which traverses the entire Hatteblech transversely and which is also effective as a reduced support surface for the beam.

In order to allow a total of at the same time a well ventilated support of the retaining plate, around the through holes for the mounting screws in the retaining plate per a Aus or high bump for receiving the screw head are provided, which simultaneously represent a reduced edition.

Of great advantage, in particular manufacturing technology is that the threaded bushing is provided centrally in the support portion in the form of an introduced by press-fitting with female thread. As a result, a greater thread height can be achieved than if only a thread would be cut directly in the relatively thin sheet metal part

The leveling aid according to the invention can be arranged on the beam of the substructure in different ways and that in each case at least two leveling each beam side are preferably mounted near the beam ends, so that a four-point support is provided by which both a height and a transverse orientation is possible.
However, it can also be provided on each side of the substructure beams more, ie more than two leveling aids, which are pairwise opposite can be arranged or at half pitch alternately left / right to the bar, z. B. at a distance of max. 70 cm. It should be understood that the width (transverse extent) of the mounting portions of the retaining plates to be fastened in the longitudinal direction of the beam is to be designed such that it is at most half the width of the beam so that two retaining plates can be fastened to the beam opposite one another, without any disturbing overlapping takes place

Of particular advantage is also that the leveling aid according to the invention in their paired arrangement simultaneously allows a connection in successive coaxial longitudinal direction of two substructure timber in a relatively problem-free manner, ie a so-called butt joint. For this, the beam parts to be joined together are brought into the required position one behind the other with abutting end faces (in abutment), then the fastening sections of the retaining plates are each halved z. B. on the left and right on each of the then overhead surface depending bolted one of the bar ends, such as a sheet metal latch, whereby two bars side by side upper four screws realize the coupling while preventing the upcoming on the bar side surfaces angle parts of the support sections lateral sliding. The central orientation of the retaining plates to the end-side investment line of the two woods to be joined is thereby substantially facilitated by the fact that in the attachment portion on the transverse center line and at the same time centrally between the mounting holes a viewing window is present, through which the retaining plate in the middle of the joint line easily visible align. If the viewing window is then configured as a square or rhombus in such a way that its diagonal runs in the transverse center axis, a central alignment in the butt joint is quick, safe and easy.

In a further embodiment, the holding plate can also be designed so that it essentially spans the entire width of the substructure timber, while on both longitudinal sides depending on a support portion protrudes transversely. It is thus only a single wide mounting portion with two support sections available, in which case the angle parts of the support sections and the inner edges of the angle parts with the bearing surfaces of the mounting portion a U-shaped clasp of Form wood. However, in order to maintain a secure support, the width dimension of the beam must not have too great a tolerance in this embodiment.

It is also possible, the fastening portions of two opposite parallel to be arranged holding plates in their transverse extent, so their width, designed so that these sections overlap in the assembled state. In this case, however, it should be noted that the screwing takes place by centrally on the beam to be mounted screws and this, especially because of variable or very high timber tolerances and also when used for beams of different width, instead of simple through holes now provide Querschtitze in the attachment section are. But it can also have only one of the two retaining plates a mounting portion with slots, while the other has the basic version with holes

In a further variant, the attachment portion and the support portion of the retaining plate are not coplanar same arranged to each other, but perpendicular to each other, in which case the attachment portion is no longer screw on the underside of the wood, but on the side surface. The angle parts of the support section are then based with its inner edge no longer on the wood, but on the side-facing surface of the mounting portion from, ie metal on metal, so that there is no fear that the narrow angle edges are too strong in the Press in wood. In this manner of attachment but there is also the possibility not to provide the angle parts on the support portion, but so that they then stand up with their lower edges on the top of the support portion, so that the support portion itself is supported vertically at the same time on the angle parts of the mounting portion ,

a leveling aid with angled mounting portion and angle parts on the support portion (fourth embodiment), and

FIGS. 16 and 17:

a leveling aid with angled attachment section and angle parts on the attachment section (fifth version).

From the in Fig.1 removable perspective view of a holding plate 1 of a leveling aid according to the invention can be seen that this consists of an elongated mounting portion 2 and a centrally projecting transversely to this support portion 3. The two rounded ends of the attachment portion 2 each have a bore 4 is associated with each with a bulge 5 (bead, expression) for receiving the head of a fastening screw and at the same time to reduce the contact surface, so as wood protection, is used. Transversely, a trough-shaped raising or vertical edge 6 can be seen, which passes through the entire width of the retaining plate, that is, both the attachment portion 2 and the support portion 3.
In the middle between the holes 4, a viewing window 7 can be seen, whose function in connection with Fig. 9 will be described in more detail, which here has the shape of a rhombus whose longitudinal diagonal runs in the transverse center line of the retaining plate.

Centered in this vertical edge 6 and at the same time centrally in the support section 3, a protuberance 8 is incorporated, which has an internal thread 9, that is an invagination with internal thread, which is a threaded bushing 10.
At the two in the longitudinal extent of the holding plate facing sides of the support portion 3, an angle member 12 is provided in each case, which is bent vertically to the extension (plane) of the holding plate upwards and has a contact inner edge 13.

In particular from Fig. 2 , but also out 3 and 4 can be seen as a retaining plate 1 is fixed to a beam 14 in such a way that the angle portions 12 of the support portion 3 with its inner edge 13 on the side surface 15 of the beam 4 and at the same time fixing the retaining plate in its longitudinal orientation.
Indicated by a broken line is here, ie in Fig. 2 , a round bottom plate 18 drawn (but could also be three- or rectangular), the center of which coincides with that of the threaded bushing 10. This sub-base is flattened or cut at its periphery, forming a section edge 19 which substantially coincides with the inner longitudinal edge 16 of the attachment portion 2 and the entire holding plate 1, in particular in connection with Fig. 3 becomes apparent.

Fig. 3 shows how the retaining plate 1 is fixed above its mounting portion 2 by means of a wood screw 20 on the beam 14 and although fitting to its circular bulge 5 and the gutter-shaped edgewise 6 and at the same time supported on the inner edges 13 of the angle parts 12th

It can be seen how a threaded spindle 22 is screwed into the threaded bush 10 of the support section 3, which extends substantially parallel to the side surface 15 of the beam 14. The lower end face of the threaded spindle 22 is supported in the lower plate 18, likewise shown here in a broken line, this support being laterally secured by an annular bulge 21. The lower end face, so the Abstüttstimseite the threaded spindle 22 is smooth, while the upper end face corresponding provisions for receiving a wrench or a screwdriver, z. B. Slot or square or hexagonal recess owns. Of course, the upper part of the threaded spindle could also be designed in the manner of a screw head, if this allows the close proximity to the side surface of the beam.
It can further be seen on the lower plate 18 that its outer edge 23 is at least slightly bent up in order to prevent any damage to the substrate, in particular if this z. B. is designed with a rubber protective mat.
From this figure it can also be seen that the minimum height of the leveling aid is determined by the total thickness of its retaining plate 1, namely by the material thickness itself and also by the height of the disc-shaped bulge 5 and the support edging 6, which are the same height , This can be a very low height of only z. B. 4 mm in the home position can be achieved. Due to the good support on the ground, secured by the lower plate 18 and the rigidity of the support portion 3 and the support by the angle members 12, also a relatively long screw 20 can be used and thus a control range of about 40 mm can be obtained.

Fig. 4 shows again the investment and mounting way of Haltebleches1 and although the screw on the wood screws 20 and the support upper lobes 5 around the screws and the gutter-shaped edging 6. Again, the minimum height and the height distance 25 can be seen and the adjustment 26th , which depends on how much the lower end face of the threaded spindle 22 is turned down.

Flg. 5 and 6 show the lower plate 18, with its section edge 19 and its bent-up edge 23. Furthermore, the annular bulge 21 can be seen, which forms a central (adjustment) receptacle for the threaded spindle 22. In this, a small hole 27 is centrally provided, which serves to drain any accumulating liquid / water Furthermore, in the surface of the lower plate 18 a plurality of recesses 28 are provided, which are shown here in the form of oval spokes. Of course, these can also be simple round or trapezoidal openings or openings of any shape or omitted altogether, since they only serve to reduce material.

In Fig. 7 is shown as on a beam 14 of a terrace substructure in each case several leveling aids on the retaining plates 1 are pairwise secured so that their threaded spindles outside the beam, however, are arranged relatively close to its side surfaces 15 parallel and at the same time vertically. In addition, it can be seen how each retaining plate 1 or each held by this threaded spindle 22 a Unterfegteller 18 is assigned and that the dimensions or inner edges or portions of the retaining plate and / or the lower plate have been chosen so that each oppositely disposed parts do not touch or hinder.

Fig. 8 also shows an arrangement of several leveling aids on a beam 14, but here the holding plates 1 are alternately fixed left / right of the beam, which has proven to be advantageous in bars with a width of 70 mm, to provide a lateral distance of 70 cm.

Fig. 9 illustrates how a bar 14 a with a bar 14 b frontally over two retaining plates can be coupled, so a beam-butt connection is easy and safe to produce. In this case, the two bars are aligned longitudinally to each other, the end faces firmly to each other, after which the other holding plate is then placed so centrally on the butt joint that the connecting line through the respective viewing window 7 in diagonal orientation is exactly visible and at the same time the two angle parts 12 fit snugly over their inner edges 13 on the side surfaces 15 of the two beam parts. Thereafter, the screw holes 4, not screwed screws 20 are screwed into the wood. After the attachment has been done on one side, the other side is moved in the same way, so that the connection is made over two total U-shaped overlapping sheet metal bolts and four screws safely.

Fig. 10 shows a vertical section along line XX Fig. 8 , Which illustrates how on the underside of the beam 14 via screws 20, the retaining plate 1 is attached. This leads to the threaded spindle 22, which 18 securely stands in the Unterlegeeller 18 in the annular recess of the plate and is supported on this on the substrate 30 and a rubber protective mat 29 thereon, wherein the bent-up Edge 23 protects against injury of the protective mat 29. Here is also to recognize that the minimum distance 25 when using a lower plate, of course, also takes into account its height, so then a minimum height is present, which consists of the total height of the Hatteblechs and the total height of the lower plate or its sheet thickness and height of the ring bulge.

Fig. 11 shows in another embodiment, a retaining plate 31, which consists of a wide mounting portion 32, and two support portions 3 with angle parts 12, which are supported laterally on the side surfaces 15 of the beam. In addition, two viewing windows 7 are provided on the transverse central axis, so that such a retaining plate 31 can also be used as butt jointing two beam pieces, in which case, however, preferably four screws instead of two central screws, ie two on each side, are used to secure the connection to increase.

Figure 12 shows a similar embodiment at first glance as in Fig. 11 except that here there are two identical retaining plates 33, 33 '(third embodiment), which are designed and fastened such that their fastening sections 34, 34' partially overlap one another. In this case, not only simple passage openings for the screws 20 are provided, but slots 35, so that a width adjustment by moving each other of the mounting portions 34, 34 'and then tightening the screws 20 is possible.

At the in Fig. 13 to 15 illustrated (fourth) embodiment now has a retaining plate 37 has a mounting portion 40 which is perpendicular to the support portion 3, which extends horizontally or transversely to the beam 14, bent and on the side surface 15 of the beam 14 fitting (ie vertically extending) is screwed. In this case, the existing on the support section 3 angle parts 12 are based on their inner edges 13 now no longer on the wood of the beam, but on the metal surface of the mounting portion 40 from. When using a Unterlegtellers is then of course (only) at least its material thickness to be considered in the calculation of the construction or minimum height.

Finally show FIGS. 16 and 17 a leveling aid in the fifth embodiment, namely with a holding plate 38, although also as in the embodiment of Fig. 13 to 15 has a vertical mounting portion 40 which is thus bent perpendicular to the support portion 3 and screwed to the side surface 15 of the beam 14. However, in this embodiment, the angle parts 12 are not provided by bending side tabs of the support portion 3, but by corresponding bending of side tabs of the attachment portion 40, so that here instead of the attachment portion adjacent inner edges now on the support portion 3 on or resting lower edges 39 are provided. <B> LIST OF REFERENCES </ b> 1.
