Description

The invention relates to a post support for wooden posts according to the preamble of claim 1 and to a method for its production, its attachment to a wooden post and its erection according to claims 13 to 15.

Post supports for wooden posts usually have the task of creating a distance between the ground and the wooden post to avoid weathering. They are known in a whole series of variants.

So are from the DE 295 03 737 U1 . DE 92 09 144 U1 and DE 90 01 221 U1 Post support or pillar supports known in which a support plate is provided, on the underside of a central extension or a threaded pin is present, which projects into a support tube of a support foot and is fixable in this. The support plate are each assigned two opposite, U-shaped headband, which form a wooden post, the side embracing post shoe. The attachment of the post carrier is made by laterally introduced via the baking-shaped headband screws. Although this makes the posts safe and stable fastened, but there is a desire in particular in the private sector z. As in garden posts, in the natural area at signs, signs, fences, etc., that the wood character of the post is consistent throughout and nothing of the metallic attachment is visible. Furthermore, the area of the support tube or the support bar should give the impression of stability and high resistance, which is ensured by an appropriate ratio of the dimensions of the post and support rod or support rod. This is not or only insufficiently the case with the aforementioned post carriers.

From the DE 296 06 117 U1 is a post carrier with a U-shaped or square post shoe known, on the underside of a support rod in the form of a reinforcing rod for walling into the ground or a four-bladed sword is provided for entry into the ground. The attachment of the post is done with side-mounted screws. Again, the above-described disadvantages can be seen, with the added that a height adjustment is not possible. This post carrier also has on its base upstanding protrusions as spacers for the post, which allow ventilation of the post from below. However, this distance is unaesthetic, as it is visible from the outside and a strainer, which becomes full with time, whereby the intended effect is lost.
Furthermore, post carriers are known in which for the frontal attachment to a wooden post on the support plate, a central pin is provided as a long cylindrical Armierungszapfen or threaded pin, which is driven in each case in a correspondingly prefabricated hole in the post or screwed. See also the DE 295 03 737 U1 and DE 87 09 769 , in which additionally holding jaws are present, also the DE 92 08 144 U1 , the DE 218 199 U1 , the DE 92 11 653 U1 and finally the French price list 06/2005 for the ground anchor FERRADIX of the company Gebrüder Sträb GmbH and Co., Wendlingen. The centric Armierungsrohre or threaded pins of the respective support plates require a corresponding central bore in the post, z. B. in the case of Pfostenträgers the company Gebrüder Sträb GmbH and Co. a bore of about 34 mm diameter and 250 mm depth. For the production of these holes special tools and special machines are required, which are the gardeners and landscapers, locksmiths or fence construction company usually not available. This applies both to the workshop of the company, and especially for on-site assembly. Since the fibers of the wood run parallel to the longitudinal axis of the post and the resistance of screws which are screwed in the fiber direction, is less than when the screws cut through the fibers in the transverse direction, the additional necessary attachment via axially introduced by the support plate screws is less advantageous , Furthermore There is a risk of splintering of the wood and thus the destruction of the connection with the screws introduced at the edge of the wooden post under load.

Finally, in the DE 198 43 293 A1 a post support (support leg) is described, in which the wooden post by means of nails or screws, which are each driven diagonally opposite each other at an acute angle into the wood, is held. The support plate used for this purpose is carried out in a first embodiment with obliquely introduced into the material holes and countersinks for the screw heads. In a second embodiment, it is angled so that the bend corresponds to a degree that offset the holes in the position of the driving direction of the nails or screws. The introduction of oblique holes in steel is extremely expensive. This is all the more true, as the support plate should have a thickness of about 8-15 mm for reasons of strength and the holes should also simultaneously provide a guide for the nails or screws. Although in the second embodiment, the angling provides the advantage of aligning the nail or screw alignment by bending the plate. However, this requires additional processing of the front of the wooden post, which is not possible on site and even in the workshop of a building yard of a city administration is not feasible. It must be carried out in a specialist company.

This design also does not allow venting of the post from below between the post and the support plate, but this is required by those skilled in the art for a corresponding longevity.

The object of the invention is therefore to provide a pole support above-mentioned genus, which is simple and inexpensive to manufacture, construction and handling, in particular the assembly with commercially available tools also allowed on site, without special preparation of the posts and with optimal ventilation of the post. In addition, the connection should be safe and visually appealing, that is, without metal parts on the side surfaces of the wooden post and with support tubes of large cross-sections.

This object is achieved by a post carrier with the features of claim 1 and by methods for producing the post carrier, for ventilating attachment of a post carrier and for setting up a wooden post with the features of claims 13-15. Advantageous embodiments are characterized in the respectively correspondingly dependent subclaims.

Accordingly, a total support plate (sandwich / total support plate) is provided, which consists of at least two superimposed disc-shaped plates, the lower base plate to the vertical or to the plate surface inclined guide holes, which are aligned with aligned guide holes in the upper mounting plates complement each forming an overall guide hole.

Thus, the invention is based on a special multi-part design of the support plate, which takes a variety of functions and is inexpensive to manufacture.

The total carrier plate thus consists of at least two plates, which together give the desired total thickness. The subdivision of the carrier plate in several approximately 3 - 8 mm thick plates allowed on the one hand a punching technology production and on the other a different shape of the stacked base and mounting plates. The expensive drilling oblique holes is eliminated by the stamping out of fixing eyes or pans in the zones of the guide holes or holes, the holes are punched before embossing. The base and mounting plates are designed in the fastening eyes or pans so that they are stackable and the oblique holes for the screws are in alignment. In this way, on the one hand, high stability and, on the other hand, a length of the guide bores which make the drillings for the drilling jig and forcibly point or guide the drill in the right direction during pre-drilling. For smaller screws there is a direct guide when screwing. For screwing a cordless screwdriver or a drill is preferably used. The distances to the support tube are dimensioned so that the drill heads have sufficient space for movement. The screws are screwed from the bottom of the base plate obliquely into the post interior.

As screws at least three relatively long wood screws are provided, which are introduced from the periphery of the total support plate, starting at an angle of about 5 ° to 20 °, preferably from about 8 ° to 10 ° inclined towards the post interior. The long screws, z. B. according to DIN 571, designed with a length of up to 25 times the screw diameter, z. B. as a screw ø 8 x 200.

Thus, the attachment of the post support to the lower end face of the wooden posts can be made easily on site, since the necessary oblique holes can be introduced in a simple manner with appropriately inclined hand drill.

The length of the screws is chosen so that there is a sufficient depth of engagement to accommodate the load acting on the compound. For this purpose, for. B. wood screws to DIN 571 to use, which there are in the length of up to 25 times the screw diameter, so with a diameter of 8 mm up to a length of 200 mm, thus screws ø 8 x 200. This case with these screws The first 30 to 50 mm no thread, which has a favorable effect on the connection, since in this threadless area no explosive forces occur through the thread. In addition, this up to 50 mm long, threadless shaft part between the screw head and the screwed-in threaded part exerts a preload on the threadless screw shaft. Since the screws are preferably arranged axially symmetrical, that is symmetrical to the axis of the post, forms a spatially acting bias in the wood within the room, which builds up in a truncated pyramid above the support plate and under the obliquely screwed screw parts.

In addition, with screws with a rolled-in thread, the thread tips are then scraped off in such a way that the outside diameter of the thread part is the diameter is matched to the threadless shaft portion, then there is the possibility that by introducing a corresponding pilot hole, the threadless shaft rests approximately free of play in this bore, which also contributes to increase the strength of the screw.

The entire carrier plate with its multiple base and mounting plates is also designed as a drilling device for the oblique holes of the screws. According to the invention, a plurality of plate parts are stacked and screwed together, riveted or screwed together, wherein the through holes for the screws are formed as oblique guide holes for the drill, with a diameter of at least the drill diameter and a length of at least the drill diameter, preferably at least 1 5 times drill diameter. As a result, the assembly is greatly facilitated at the construction site and achieved with great certainty the desired inclination of the screws.

By constructing the overall carrier plate as a multi-plate structure (sandwich construction), its strength can be determined by increasing or decreasing the number of plates. The pan impressions on the individual plates of the overall carrier plate are designed so that the carrier plates are stackable and the embossments also act as reinforcing beads.

Of particular advantage is that only aeration of the layer between the total support plate and pole sole is required for the ventilation of the post, which is done by the special design of the support plate with various holes, holes, openings and / or slots. For this purpose, the upper mounting plates are provided with ventilation slots, which ventilate the post base from below. Air is supplied through holes or openings in the lower base plate. The slots and openings or holes are designed so that in addition an air circulation between the outside world and the interior of the support tube can take place. The support tube itself, with its approx. 1 - 2 liter capacity, serves as an air reservoir whose air density changes with the change of the outside temperature d. H. Day and night, summer and winter constantly changing and this change compensates by an air circulation with the outside world. The holes in the lower base plate also cause the passing wind causes a venturi effect and entrains air from the inside and this is fed from the opposite side again or as opposed to a negative pressure and air is sucked.

Through this design, the viewer of the post carrier is shown a solution completely without post shoe and still with optimally ventilated post.

In order to give the impression of reliable strength visually in this connection, the ratio of post diameter or post diagonal to the support tube diameter should not be less than 4: 1, wherein the support tube diameter adapted to z. B. the diameter of the holding tube of the ground dowel is chosen, or vice versa, in correlation z. As a ground dowel or ground foundation of the company Gebrüder Sträb GmbH & Co. as in DE 102 40 586 described in which z. B. a 40-, 50- or 60-mm pipe is present or corresponding support tubes of post carriers are used.

In order to be able to maintain a thick support tube with relatively thin wooden posts, whereby possibly the guide bores of the support plate are arranged radially very close to the lateral surface of the support tube, it is advantageous if the support tube are radially folded or pressed in these zones of the screws so far, that there is enough space for the drill chuck or the nut of the drive shaft of a cordless screwdriver.

It is also advantageous that for the exact height of vertical spacing during assembly, a spacer tube which can be pushed over the support tube and is supported between the support plate and the upper side of the ground anchor is provided. This also has the advantage that this spacer tube can also achieve a positive visual effect by color or shape, z. B. over longitudinal or circumferential grooves special optical effects can be achieved.

The improvement of the holding force of the screws and a filling of any resulting cavities during pre-drilling can be achieved by brushing the screws with cold glue before screwing.

According to the inventive method for attaching a post to a pole support according to the invention are frontally in the wood posts, with the aid of the support plate as a template, pre-drilled with a drill holes with a length of about 20 to 50 mm, the inclination to the post axis of 5 ° 25 °, preferably about 8 ° to 10 °. In these pre-drilled holes, the long screws are then directly introduced or screwed in soft woods and in harder woods before each added an additional corresponding deeper continuing smaller pilot hole.

Is then still serving as a template support plate fixed before inserting the holes on the post end face, z. B. on at least two nails, for which purpose two holes are provided in the carrier plate. For fixing can also be formed on the support plate shaped hooks or nail-shaped projections, but this is more expensive. As a result, the support plate and thus the whole post carrier undergoes optimal alignment on the post and also the operator both hands free for safe handling of the drill and then screwing.

• Entsprechend dem Querschnitt des Pfostens und des zu verwendenden Bodendübels ist ein demgemäß ausgelegter Pfostenträger zu verwenden, der über die obere, ebene Stirnfläche seiner Gesamt-Trägerplatte an der unteren Stirnfläche des Pfostens entsprechend ausgerichtet aufgelegt und über z. B. zwei Nägel an dieser angeheftet, d. h. befestigt wird.

• Nach entsprechender axialer Ausrichtung des Pfostens wird schließlich der Pfostenträger im Dübel festgesetzt, z. B. durch Anziehen der Schrauben der Druckplatte des Dübels oder durch Festspannen über den elastischen Druckring des Dübels.

Considering now the structure of the post carrier including its ventilation system, the manufacturing process and the method (procedure) for its attachment to a post as well as a total supported supporting a wooden post in the ground using the knowledge or objects according to the invention, then are for the achievement an optimal result, that is a relatively easily deployable post, with pleasing appearance, the following steps necessary or empfehlendwert:

• According to the cross-section of the post and the ground anchor to be used a accordingly designed post carrier is to be used, which extends over the upper, flat end face of its entire support plate on the lower end face the post appropriately aligned and laid over z. B. two nails attached to this, that is attached.
• Now a drill with the right drill is taken to hand and placed on the inclined guide holes in the support plate, the correspondingly inclined pilot holes in a length of about 5 cm, if necessary, with a smaller drill bore correspondingly long continued.
• Then the long screws, z. B. screws ø 8 x 200, coated with cold glue, introduced over the guide holes of the support plate and further into the pilot holes and then z. B. completely screwed in with a cordless screwdriver.
• Now a ground dowel is placed at the desired location in the ground, z. B. hunched vertically, taking into account a correct vertical orientation.
• After selecting a spacer tube of dimensions as required, this is pushed over the support tube of the post carrier, after which the post carrier, with post attached thereto, is introduced vertically via its support tube into the holding tube of the ground anchor and deposited until a full support via the spacer tube takes place.
• After appropriate axial alignment of the post, the post carrier is finally set in the dowel, z. B. by tightening the screws of the pressure plate of the anchor or by tightening on the elastic pressure ring of the anchor.

The invention will be explained in more detail with reference to several embodiments with reference to the drawings.

As in particular from Fig. 1 and 2 can be seen, there is an inventive post carrier 1 in the first embodiment essentially of a base plate 2, which has a support tube 6 on its underside.

On the principle even top side of the base plate 2 is resting at least one further mounting plate 3 of which in Fig. 1 and Fig. 2 in each case such a base mounting plate 3 and a further secondary mounting plate 4 are shown. The base plate 2, the mounting plate 3 and the second mounting plate 4 are firmly connected by screws 7 (see Fig. 2 + 3) and form the total support plate 5. On the top mounting plate 4 is a post 8, which preferably consists of wood and is held on obliquely introduced wood screws 9 to the overall support plate 5. It can be seen that the four screws 9 are each inclined in the direction of the center axis of the post 8 and the entire arrangement, so that intersect their axes at a common point on this central axis. Furthermore, it can be seen that the length of the screws is greater than the width of the total support plate 5, that is, they penetrate deeply into the wood. This results in a screwing of less than 30 degrees to the longitudinal axis of the post. The screws 9 are generally known long wood screws, preferably according to DIN 571, which have a threadless shaft 10 on the head side and subsequently a long threaded part 11.

The base plate 2, with the mounting plate 3, and the second mounting plate 4 have each in the penetrated by the wood screws 9 (corner) zones a punching technology introduced grading in the form of a staggered downwards (Step) pan 12. In this case, base or mounting plates 2, 3, 4 are designed so that their step pans 12 each match, whereby they are interlocking stackable and thereby stabilize each other. In the plates 2, 3, 4, the (guide) holes 13 are also inclined according to the inclination of the screws 9 and at the same time offset accordingly, so that in the overall support plate 5 at its triple plate height in each case an aligned guide bore 13 with corresponding Length (height of the 3 plates) for drill guide or direct screw-in guide is available.

In addition, it can be seen that two nails 14 are also passed through the overall carrier plate 5, formed from base plate 2, mounting plate 3 and secondary mounting plate 4, for which holes 15 are provided, which are hammered into the post 5. These nails 14 are used during assembly for prefixing serving as a template drilling total carrier plate. 5

Out Fig. 1 It can be seen that the base plate 2 in the center has a ventilation hole 16 which is slightly smaller than the inner diameter of the support tube 6. In addition, coaxially smaller ventilation openings 17 are provided in the plates 3 and 4. Furthermore, in particular Fig. 2 to recognize that in the mounting plate 3 and the secondary mounting plate 4 ventilation slots 18 are introduced, through which they are provided with many cavities.

The support tube 6 of the post carrier 1 projects axially into the holding tube 22 of a ground anchor 23 and is held in this in a known manner (see ground anchor of the applicant, in particular according to DE 102 40 586 C2 ). The locking of the support tube 6 in the holding tube 22 is achieved in the ground anchor 23 so that by screwing screws 24, a pressure plate 25 is pressed in the direction of the dowel bell 26, whereby a zwischenbefindlicher elastic pressure ring 27 is deformed radially inwardly, thereby holding the support tube 6 ,

In Fig. 3 is the post carrier after Fig. 2 shown as an exploded view in view from below. In this case, all functional parts are individually visible, namely the lower base plate 2 with attached thereto support tube 6, about the middle mounting plate 3 and finally the upper (second) mounting plate 4. It shows the four screws 7, which the three plates 2, 3rd , 4 connect together. In the mounting plate 3 and the second mounting plate 4, the therein provided radial ventilation slots 16 and the central ventilation openings 17 are clearly visible. On the base plate 2 also several air supply openings 19 are shown. Well recognizable are also the characteristics of the stepped pans 12 and the wood screws 9 and the strongly rounded corners 20 of the plates 2, 3, 4, by which a use of this design is possible both on square and round post 8.

As a whole out Fig. 1, 2 and 3 can be seen, while the step-shaped mounting pans 12 are each arranged in the corners of the square support plate 5, that is in each case diagonally opposite. It is in particular from Fig. 1 to recognize how the guide holes 13 are inclined inwards towards the center axis of the post carrier, or the entire arrangement, and as by the correspondingly high or long design of the guide holes 13 with a length of at least 1.0 times, preferably min , 1.5 times the diameter of a safe, accurate guidance and thus the suitability is given as a drilling template.

In Fig. 4 a post carrier 1 is shown, which in principle has the same structure as the post carrier 1 according to Fig. 1 and 2 has, except that here is a section according to the lines IV-IV Fig. 2 was selected and the mounting pans 12 and the wood screws 9 are not shown. In the interior of the hollow support tube 6 is an air reservoir 29. The air from this memory communicates with the outside air through the inner ventilation opening 16 of the base plate 2, the ventilation slots 18 of the mounting plate 3 and the second mounting plate 4 and the air supply openings 19 of the base plate. 2 When the air reservoir is heated by heating the support tube 6, the air expands and escapes, while the air contracts on cooling of the support tube and fresh air flows in via the air supply openings 19. Of course, fresh air is also conveyed to the lower end face of the post via the centric ventilation openings 17.

Fig. 5 shows in principle the same view as Fig. 4 However, wherein the air storage limiting ground dowel 23 is not shown. In the mounting plate 3 and the second mounting plate 4 are centrally impressed truncated impressions 30, so that these plates get a stiffening analogous to a bead, for the second, the contact surface of the air is increased to the post bottom and the third, the slope 31 as baffle for outgoing and incoming air is used.

By the straight (horizontal) arrows 32, the passing by the wind on the support tube 6 air is shown. As a result of the Venturiwirkung tears the wind flow from the air reservoir 29 with. The air is thus sucked in again by the negative pressure in the non-wind flow louvers 18, 19, which in turn serves the ventilation of the underside of the post 8.

In 6 and 7 a post carrier 1 is shown, which carries a post 8 in the situation during the introduction of the pilot holes for the screws 9 during the assembly work. It can be seen that the support plate 5 is attached via nails 14 on the front side of the post 8, so that it can be safely used as a drilling template for introducing the pilot holes. It can also be seen that the diameter ratio between the post 8 and the support tube 6 is such that between the guide holes 13 and the lateral surface 33 of the support tube 6, a sufficiently large distance is present, the unhindered work with z. B. a hand drill 34. In this case, when inserting and advancing the drill 35, the drill chuck 36 holding the drill can be freely moved in the corresponding slope. With soft wood or when using smaller screw diameters, the screw can be driven directly into the wood instead of pre-drilling with the aid of a drill or a bit-screwdriver.

In 8 and 9 is shown as in a similarly constructed round post support 1, the ratio of the diameter of posts 8 and support tube 6 is such that the distances between the guide holes 13 to the outer periphery (lateral surface 33) of the support tube 6 is so small that the chuck 36 during insertion of the Pre-drilling for the screws does not fit. In order to enable these operations, indentations or folds 37 are respectively provided in the zone of the screw holes 13 and the corresponding cup 12, which are introduced so that a channel is formed, which runs substantially parallel to the drill alignment.

These 8 and 9 also show that the number of three screws is sufficient for the production of a spatial structure and this space structure has a symmetrical shape.
