Technical area

The invention relates to a carrier composite system with at least two interconnected carriers. It relates in particular to a mast arrangement.

State of the art

Medium- and low-voltage networks use wooden pole arrangements that carry trusses to which power lines are attached. The trusses are usually steel tubes or double T-beams made of steel, which are connected to the wooden mast assembly via angled U-profiles, the U-profiles are attached with clips at the top of the wooden pole assembly. The wooden pole arrangement can consist of a simple, anchored in the ground, upright wooden pole. Often also wood double masts are used. The double masts may, for example, be in the shape of the outer legs of an A be arranged, wherein they are held together at its upper end by guided through threaded rods and are arranged underneath at different heights cross struts for stabilizing the masts. In another embodiment, the masts formed from each round timber run parallel, with double T-pieces are provided as spacers between the masts and the masts respectively at the level of the double T-pieces over long bolts that passed horizontally through the mast are pressed to the double tees.

A considerable disadvantage of the known wooden mast constructions is that their statics can not be calculated. A key reason for this is that the wooden masts expand to different extents due to changes in ambient temperature and humidity. Therefore, the design of wooden poles in terms of their thickness and the size and type of fasteners based on empirical experience with the disadvantage that the types used are not economical.

In contrast, the invention has for its object to provide a carrier composite system that is statically predictable and can be designed with the mast arrangements load-oriented and cost-effective.

Inventive solution

This object is achieved with a carrier composite system having the features of claim 1. Preferred embodiments of the invention will become apparent from the dependent claims. A composite anchor is understood here and below to mean a component having a core which carries a large number of anchor pins. The core may have a symmetrical or asymmetrical shape. Elongated cores with a square or diamond-shaped cross section have proven to be practically relevant core shapes. But it can also be used as polyhedron cores or other symmetrical or asymmetrical cores used.

Depending on the field of application, the anchor pins may extend in opposite directions only parallel to one another or on opposite sides of the core. Also, a composite anchor as a node connection for two or more carriers with at least two acting in different directions anchor pin areas, especially if the core is a polyhedron. The anchors can be designed according to need with one or more through holes longitudinally or transversely through its core and serve as a so-called push-through anchors as a bearing for threaded pins. You can also have threaded holes for screws to be attached to the anchor.

The anchor pins may have a round or polygonal cross-section, and be formed in particular as thorns. The composite anchors may be integrally or multiply formed from one or different materials.

It has surprisingly been found that when tensile anchors are provided with anchor pins as connecting elements, both tensile and compressive forces as well as the shear and shear forces occurring between the carriers to be connected are transferred particularly well, because the anchor pins do not transmit the forces on the outside of a carrier on this, but initiate into its interior. As a result, the introduction of force from the geometric extent of the carrier is largely independent. A mast arrangement based on such a carrier composite system can be statically calculated for the first time, so that the selection of the materials used and the material thicknesses can be determined for the first time on the basis of calculations of the expected load cases.

The materials for the carriers and the composite anchor can be selected so that the composite anchor can be pressed into the outer surface of the carrier. This is possible in particular when the mast in the region of the anchor receptacle has a rubber-like material which has elastic properties within certain limits. In particular, when the anchor pins have one or more undercuts, so that the formed by the undercuts circumferential edges of the anchor pin press into the surface of the resulting from the press-fitting, the composite anchor can sit firmly in the recording.

However, recesses are preferably provided on the outer surface of the carrier, especially in wooden supports before the anchor pins of the composite anchor are inserted into the receptacles in the outer surface of the carrier.

In a further preferred embodiment of the supporting structure construction according to the invention, means are provided for securing the composite anchor engaging in the receptacles in the outer surface (s) of the carrier (s). As such means come in particular mechanical Fastening means, in particular screws or bolts into consideration, for example, engage directly in the carrier, be it parallel to the anchor pins or obliquely thereto, wherein the fastening means are preferably directly in communication with the composite anchor. As connecting agents but also suitable adhesives, for example, two-component adhesives into consideration.

Other attachment options include, for example, to secure the composite anchor with a cross around the composite anchor and the carrier clamp on the carrier. Also, the composite anchor can lie directly between two or more carriers, these carriers can be held together with other fasteners such as screws, clamps or the like, so that the composite anchor is securely held in position between the carriers.

In particular, in two, but also in several mutually adjacent carriers, it makes sense that the composite anchor is provided with anchor pins for each of these carriers and engages with these in the carrier in order to achieve the best possible transfer of forces from carrier to carrier.

However, embodiments are also preferred in which the composite anchor has only anchor pins for one of the carriers to be connected and is connected to another carrier via other means. Thus, a composite anchor, which engages on one side with anchor pins in a mast and is fastened for example by a screw on the mast, be connected on the other side with a cross-member carrying U-profile, for example via rivets, a weld or a screw. If the carriers connected to one another via a composite anchor at least partially abut each other, it is advantageous if they are flat in the abutting areas. In particular, when the masts are made at the point where they are to be set up, creating a planar abutment surface is much easier than creating a profiled surface.

The structure according to the invention is, as already stated above, particularly suitable for pole arrangements, in particular for use as poles in medium-voltage, low-voltage and high-voltage networks up to 360 kV, or for use in telecommunication networks, e.g. Telephone transmission towers. They can optionally be provided with a crossbar which is connected to the mast arrangement via one or more composite anchors.

Suitable mast arrangements consist, for example, of at least two A-shaped, interconnected, interconnected anchors, upright carriers. Preferably, a mast arrangement can be formed in three sockets with three upright carriers, which are connected to one another via one or more composite anchors.

The mast arrangements according to the invention can be provided with stiffeners for their stiffening. Such cross beams may have an internal composite anchor, as it is known for example from DE 297 23 866 Ul, engage in cooperating with at least one of the upright support mechanical connecting means, such as bolts. The carrier composite system according to the invention is particularly suitable for carriers made of wood or a wood composite material and is particularly suitable for supporting works made of round timbers. However, the carriers may also consist, for example, of a plastic material, a concrete material or other suitable materials.

In addition to the composite anchors already described above, those which have at least one web, preferably with at least one through-hole, are also preferred. The webs of the composite anchors according to the invention can serve, in particular, to secure a composite anchor inserted into a (hollow) carrier and with its anchor pins into engagement with screws on the carrier against slipping out. For this, the shape and orientation of the webs can be adapted to the outer surface of a carrier to which they are to be applied. For example, depending on the requirements, they can be curved or project obliquely from the core.

Also, the composite anchor may have a continuous contact surface formed by an outer surface of the core and an outer surface of at least one of the webs for a carrier, which is curved, for example, flat or transverse to the longitudinal axis of the composite anchor as required.

In a further preferred embodiment, the composite anchor has a through hole extending in the direction of the longitudinal axis of the core, in particular a through hole. Thus, the anchor can serve as a receptacle for a guide or locking pin over which other carrier or functional parts are connected to the anchor can, such as horizontal support profiles for receiving transformers or the like. In particular, with anchor cores with through-hole, it is advantageous if the armature core has at least two mutually spaced, mutually aligned armature core parts. Thus, on the one hand, the material required for the production of the anchor and thus also its own weight can be reduced. On the other hand, however, such an embodiment also offers the advantage that a composite anchor constructed in this way can be connected to one or more support and / or functional elements via more than one guide or locking pin.

The composite anchors are preferably produced as castings due to the simple shape. Suitable materials are metal alloys into consideration; but it can also be used, for example, readily plastics.

Ways to carry out the invention

The carrier construction shown in FIGS. 1a and 1b consists of a single mast 1, a crossbeam 2, formed from a round timber and two U-profiles 3, 4, which are arranged on opposite sides of the single mast 1, a lower, parallel to the side surface of the single mast 1 extending region and an upper, obliquely outwardly extending region and at the upper ends of the traverse. 2 is stored.

The U-profiles 3, 4 are connected to the single mast 1 via in each case an upper composite anchor 5, 6 and a lower composite anchor 7, 8. The composite anchors have an elongated core. At the core in each case eight parallel arranged in two rows anchor pins are provided which extend perpendicular to the bottom surface of the U-profiles and towards the single mast 1 out. The anchor pins engage in recordings 9, 11 provided in the single mast 1. The composite anchors 5, 6, 7, 8 are connected to the respective U-profile 3, 4 on at least one side of its core and can simply be screwed or welded, for example, with this on its side facing away from the single mast. In a preferred embodiment, the core of the composite anchor on at least one bore along its longitudinal axis as a receptacle for a guide pin attached to the U-profile. Examples of such anchors will be described with reference to Figures 7a, 7b, 7d, 8, 9a, 9b, 9c and 9d.

At the composite anchors 5, 6, 7, 8 are provided parallel to the outer surface of the single mast 1 provided webs 12, 13, 14, 15, which as an abutment for screws 16, 17, 18, 19, 21, 22, 23, 24, 25th , 26, 27 are used, which are screwed into the single mast 1 in order to secure in particular against slipping out of the composite anchors 5, 6, 7, 8. The screws extend radially in the direction of the central longitudinal axis of the single mast. 1 FIGS. 2 a and 2 b show another embodiment of a carrier composite system according to the invention, this time with a double mast 31 consisting of two parallel roundwoods 32, 33. The logs are held together by means not shown, passing horizontally through them bolts. Between the round timbers 32, 33, an upper composite anchor 34 and a lower composite anchor 35 are arranged. Both composite anchors 34, 35 each have a horizontally extending, elongate core 36 whose longitudinal axis is tangent to both roundwoods. The composite anchors 34, 35 also have a plurality of mutually parallel anchor pins, which engage on both sides of the core from the outside into corresponding recesses in the round timber.

Both composite anchors 34, 35 each have at both ends threaded holes in the screws 37, 38, 39, 41 are screwed for fixing U-profiles 42, 43, wherein the U-profiles 42, 43 as in the in FIGS and Ib embodiment shown above the mast extending Traverse 44 hold.

The carrier composite system shown in Figures 3a to 3d differs from that shown in Figures Ia and Ib only in that instead of the single mast 1, a double mast from two mutually parallel round logs 51, 52 is provided, not shown here, by both Round logs 51, 51 'horizontally passing bolts are firmly connected to each other, wherein the U-profiles 52, 52' connected upper and lower composite anchors 53, 53 'engage in the opposite outer sides of the double mast. In the cores of the composite anchors 53, 53 'are vertical extending through holes provided in the guide pin 54 'engage, which are firmly connected via tabs 55' with the U-profiles 52 'and secured by pins 56' at their free ends against being pulled out.

In both embodiments with double masts can be provided for stabilizing the masts against each other therebetween, preferably - as shown in Figures 3b and 3c - vertically, but also horizontally or obliquely arranged composite anchors 57 which engage with anchor pins provided on both sides in the masts.

In the figures 4a to 4c, a simple mast construction with a vertical single mast 61 is shown, which is embedded in the bottom 62 and stabilized at its lower end via a cross member 63. The single mast 61 is supported by a likewise inserted into the bottom 62, obliquely attached to the upper end of the single mast 61 strut 64. Strut 64 and single mast 61 are connected in the area in which they abut each other via an elongate composite anchor 65 which is vertically arranged and engages with its anchor pins in both the single mast 61, and in the strut 64. Strut 64 and single mast 61 are also connected to each other via an upper bolt 66 and a lower bolt 67, so that the composite anchor 65 is secured against slipping out of position.

FIGS. 5a to 5d show another mast construction with an A-mast 71. The two essentially upright supports 72, 73 which run up to one another are flat in the head region 74 (see Fig. 7c) on their mutually facing sides. In these Flat areas are recesses for each core and the anchor pins of a first, upper, horizontally extending between the two surfaces of composite anchor 75, a second, arranged underneath, vertically extending composite anchor 76 and a third, under the second composite anchor 76 horizontally extending composite anchor 77 is provided. The supports 72, 73 are also connected to each other via horizontally passing therethrough, above and below the and between the composite anchor (s) 75, 76, 77 arranged bolts 78, 79, 81, 82.

A traverse can be attached to this mast, for example via profiles on the upper and lower composite anchors 75, 77. For this purpose, the composite anchors can be provided with through holes passing through their core through holes or frontally with threaded holes, so that the profiles are either to be attached via threaded rods or screws to the composite anchors.

At approximately half the height of the A-mast 71, a carrier 83 extending horizontally between the carriers 72, 73 is provided, which is shown somewhat more clearly in the detail view of FIG. 5d. The carrier 83 has a through hole extending along its longitudinal axis into which a further composite anchor 84 is embedded. The composite anchor 84 has threaded bores that cooperate with bolts 85, 86 passing through the beams 72 and 73 and the through hole of the beam 84 and with which the beams 72, 73 are fixedly connected to the cross member 83. Both carriers 72, 73 are embedded in the bottom 87 and stabilized in the ground via two horizontal cross bars 88 connecting the carriers 72, 73 and bordering on both sides.

The mast construction illustrated in FIGS. 6a to 6c differs from that shown in FIGS. 5a to 5d essentially in that, instead of two substantially upright carriers, three carriers 91, 92, 93 are provided which are in the form of a three-legged tripod are arranged. All carriers are embedded in the bottom 94 and in the ground over parallel, horizontal cross bars 95 in pairs edged and stabilized. Also, the carriers 91, 92, 93 via cross members 97, 98, 99 connected to each other at about half the height of the mast.

At their upper ends, the carriers 91, 92, 93 each have two planar surfaces enclosing an angle of 120 ° as contact surfaces for the respective other two carriers. Recesses for the cores and anchor pins of composite anchors 101, 102, 103 are in turn provided in these surfaces which, depending on the embodiment, can optionally be arranged horizontally and / or vertically between the abutting sides of the carriers 91, 92, 93. If the composite anchors are arranged horizontally, as shown in the detailed view of FIG. 6b, the composite anchors 101, 102, 103 can have threaded bores on their outwardly directed end faces, via which, for example, the traverse 104 shown in FIG. 6a can be fastened to the head of the pole construction , For this purpose, for example, three substantially vertically extending profiles evenly distributed in the circumferential direction flanged on the underside of a horizontal plate or otherwise be attached, with the crossbar sitting on the plate and is held by this.

As in the exemplary embodiment illustrated in FIGS. 5a to 5d, a plurality of composite anchors can be arranged one above the other, optionally in horizontal or vertical, and optionally also oblique orientation, between the adjoining surfaces.

As can be seen in particular from the simplified cross-section shown in FIG. 6c, the abutting surfaces of adjacent carriers 91, 92, 93 are also pressed together by bolts 105, 106, 107 running perpendicular to the surfaces through the carriers 91, 92, 93 ,

The illustrated three-legged mast construction made of wood is particularly suitable for use for power poles for branches, which are usually carried out so far made of steel.

FIGS. 7a to 7d show various types of armatures which can be used for the carrier composite systems according to the invention.

Fig. 7a shows a composite anchor having a core 111 which has a substantially square cross-section. Through the core 111, a through hole 112 extends. On two adjacent longitudinal sides 113, 114 of the core 111 mutually parallel anchor pins 115 are arranged, the longitudinal axes each form an angle of 45 ° to the respective outer surface on which they are arranged. The anchor pins 115 are conical with a tapering away from the core Cross section formed. On the other two longitudinal sides 116, 117 are in a plane which is perpendicular to the longitudinal axes of the anchor pins 115, close to this parallel central plane of symmetry of the core 111 and near its two end faces extending away from this webs 116 each having a through hole 117 to Attachment of the composite anchor provided on the support via screws, for example.

The composite anchor illustrated in FIG. 7b differs from that illustrated in FIG. 7a only in that counterbores 121 are provided at one or both end sides of the composite anchor at the entrance of the through-hole for receiving the countersunk heads of countersunk screws.

The principle of this composite anchor with only one side facing anchor pins can be varied varied. Thus, the through hole 112, for example, have threads on the front side or can be provided instead of the through hole at one or both ends threaded holes. Also, the core can be designed as a solid core without drilling. The webs may, instead of lying in a plane perpendicular to the longitudinal axes of the anchor pins, be arranged so that they rest in the installed state, for example on a non-aligned surface of a carrier to which the composite anchor is to be attached. For this purpose, the webs can also be curved. Also, the armature pins facing away from the outside of the core, which lies between the webs, with the adjoining sides of the webs form a continuous surface and in particular be flat. Furthermore, threaded bores for fastening carriers may be provided on the outside of the core facing away from the anchor pins. The composite anchors described are particularly suitable for connecting a wooden support, in particular a wooden mast, with a support made of another material, such as steel or concrete.

The composite anchor shown in Fig. 7c differs from that shown in Fig. 7a in that it has a solid core 131 and on all longitudinal sides of the core 131 anchor pins 132, 133 are provided, wherein the longitudinal axes of the anchor pins with the outside, at which the Anchor pins are each arranged, in turn, include an angle of 45 ° and all extend in parallel planes.

The composite anchor illustrated in FIG. 7d differs from that shown in FIG. 7c merely by a through hole centrally extending in the longitudinal direction through the core 134.

The last two types of anchor described above are often varied as well as the previously described, in particular with regard to the number, arrangement and design of through holes, holes, and anchor pins, as well as the design of the core cross-section, and are particularly suitable for connecting two wood beams.

Usually sufficient for safe transmission of shear and shear forces 1 to 3 composite anchors per each adjacent surface pair of adjacent carrier. However, the actual, and moreover required, number of composite anchors per surface pair will always result from the expected static and possibly also dynamic loads. There are also anchor types with a three-, four- or polygonal core cross section used, at which extending perpendicular to the longitudinal sides anchor pins for simultaneous connection of three or more components are provided. Anchor types with anchor pins pointing in several directions are particularly suitable for connecting several wooden beams.

The composite anchors shown in FIGS. 8 and 9 a to 9 d essentially differ from that shown in FIG. 7 a in that their core 141, 151, 151 'and the webs 142, 143 extending on both sides of the cores 141, 151, 151' , 152, 153 on the side of the anchor pins 144, 154 a continuous contact surface 145, 155, wherein the cross section of the core 141 in Fig. 8 two perpendicular to the contact surface 145 and mutually parallel side surfaces 147, 148 and the plant surface opposite outer surface 149th having a circular section-shaped cross section and the cross section of the core 151, 151 'in Figs. 9a to 9d is substantially semicircular. The webs 142, 143, 152, 153 extend over the entire length of the core 141, 151, 151 'and are provided with a plurality of - in the illustrated examples six - through holes 146, 156.

Both anchor cores 141, 151, 151 'have through bores 150, 157 extending in the direction of their longitudinal axis.

In the composite anchor shown in Figure 8, the contact surface 145 is flat. The through holes 146 are respectively disposed at the height of the anchor pins 144. The contact surface 155 of the composite anchor illustrated in FIGS. 9a to 9d is concave in the anchor longitudinal direction, as can be seen in particular in FIGS. 9a and 9c. The through holes 156 are disposed at half height of the anchor pins 154, respectively. As can be seen in particular in FIGS. 9b and 9c, they can have counterbores 158 for receiving countersunk heads of countersunk screws at their ends remote from the contact surfaces 145, 155. In addition, it may be advantageous if the webs 142, 143, 152, 153 are made comparatively thick at least in the region of the through holes 146, 156 in order to align screws passed through them and thereby facilitate their precise screwing into a carrier.

The semi-circular body of the armature core need not extend over the entire length of the composite anchor. Rather, it may be formed from two or more mutually spaced, but mutually aligned anchor parts 151, 151 ', for example, to keep the mass of the composite anchor low (see Figure 9d). If the body of the armature core 151, 151 'is interrupted, it can be used as a receptacle for two guide pins arranged one above the other.

All illustrated composite anchors are particularly suitable for use on wooden poles. So they can be easily screwed to wooden poles with self-drilling wood screws. This results in particular the advantage that the wood screws record not only acting on the connection of composite anchor and wooden mast tensile forces, but also in addition to the anchor pins thrust and shear forces loads. The wood screws do not run parallel but obliquely the anchor pins, in particular when the associated webs of the composite anchor are arranged correspondingly obliquely or its continuous contact surface is curved, take the wood screws tensile forces in different directions, whereby the shear anchor particularly well secured in position and part of the shear and shear forces of the screws is absorbed as tensile forces.

FIGS. 10a to 10c show a connecting element consisting of a guide pin 161 and a tab 162, which are welded to the lug 162, for example, to a U-carrier and can be inserted with its guide pin 161 into the through bore of an armature core. The tab 162 is comparatively flat and has in plan view substantially the cross section of an isosceles, right-angled triangle. The right angle opposite end face of the tab 162 serves as a welding edge for welding to a carrier, such as e.g. the mentioned U-beam. At the bottom of the tab 162 of the guide pin 161 is arranged, which has at its free lower end a transverse to its longitudinal axis extending through opening 163 for receiving a Sicherungssplintes.

FIG. 11 shows a further possible application of the carrier composite system. In the upper region of the two masts 171, 171 'are each at the same height on opposite outer sides of the A-mast piercing anchors 172, 172', which correspond in their design to the through-hole anchors 172, 172 'shown in Figures 9a to 9d arranged and parallel aligned with the longitudinal axis of the masts 171, 171 '. On the upper ends of the push-through anchors 172, 172 'are mutually parallel and horizontally extending U-profile support on both sides of the A-mast 173, 174 arranged. The carriers 173, 174 are fixedly connected to the A-mast via bolts 175, 175 'passing through them, which engage in the through bores of the composite anchors 172, 172'. In addition, they are connected at both ends by bolts 176, 177. On one side of the A-mast both beams 173, 174 cantilevered out and form a footprint for a load 178, for example for a transformer.

FIGS. 12a and 12b show a further variant of the carrier composite system according to the invention. In the example shown on a mast 181 two parallel to the longitudinal axis of the mast 181 aligned through anchor 182, 183 in the manner of the through anchor shown in Figures 9a to 9d above the other and laterally offset from each other. A carrier element 184 can be fixedly connected to the mast 181 via guide pins 185, 186 which are fastened to one another via lugs 187, 188 correspondingly one above the other and laterally offset from one another and engage in the push-through anchors 182, 183.

The composite anchors shown in FIGS. 8 and 9a to 9d and the composite system illustrated in FIG. 12 are also particularly suitable for fastening a plurality of elements or functional parts to masts, such as lighting devices.
