Description

The invention relates to a railing kit according to the preamble of claim 1. Railings can be put together using such kits, specifically for blocking and / or accident prevention, in particular in the area of stair flanks, floor flanks of buildings or the like, whereby to achieve a safe Stop also in the event that at least parts of the railing are only to be provisionally provided during construction or as temporary railings, at least one fastening device is provided to secure the position of at least one railing kit.

The railing kits expediently form a railing system which contains at least one railing post which, for its fastening on the building side, has a fastening device which is designed as a tensioning device and has a tensioning element which can be moved relative to the post body.

Safety devices against accidents must be attached to buildings during construction or until completion, for which it projects freely, for example in the area of stairs Floors, balcony slabs or the like. It is expedient to arrange a temporary railing and to make it removable, so that it can be removed again as soon as the railing intended for the finished building can be installed or no special securing is required.

DE-A 29 10 325 shows a railing post on which a hook-shaped receiving pocket for a board serving as a railing longitudinal run is attached. A pivotable eccentric is provided on this hook, with which the board can be clamped in the pocket against the railing post. So there is a pure frictional connection.

From US-A-3 848 854 a railing kit with longitudinal runs has become known, which are telescopically adjustable relative to one another and can be locked by separate plug-in brackets, which engage in congruent plug-in openings on the upper edges of the longitudinal runs so that the longitudinal runs can fall out downwards. This can only be prevented by using separate wooden wedges, without which the parts would inevitably have movement play against each other. The wedge tensions the outer longitudinal run against a component, but not the longitudinal runs directly against one another, since this has transverse play relative to one another. Plug-in bracket and wedge are separate, lost parts that quickly disappear on construction sites.

A construction railing has become known from DE-A-29 37 234, in which railing posts fastened in sleeves are provided with railing longitudinal rails made of wood, each having a round hole and an elongated hole. The longitudinal runs thus adaptable to certain differences in length between the railing posts are fastened to the railing posts by screws which pass through the holes in the longitudinal runs and Corresponding holes are inserted in the railing posts and tightened using a nut screwed behind them. The fastening parts for the longitudinal runs are separate, loose parts.

From FR-A-2 595 741 a railing post has become known which has a collet for fastening on the building side, which can be actuated from the upper end of the railing post via a spindle. From FR-A-2 417 608 a holder with an inner tendon has become known, which can be braced by inclined surfaces with respect to a sleeve, which is to be fixed beforehand on the building side by concreting.

The object of the invention is to provide a railing system which prevents the disadvantages of known solutions and, in particular even with a detachable design, enables easy-to-use position securing and quick assembly and disassembly.

The features of claim 1 serve to solve this problem. A railing with a handrail is therefore proposed, which is formed by a length-adjustable profile made of metal or the like and is e.g. can be adapted in length to the respective installation conditions in the manner of a telescopic rod. Your fastening device is suitable as a tensioning device for securing the railing rod relative to the railing post (s) without play, but releasably. The individual components of this tensioning device are captively provided on the railing post.

For many applications, it is advantageous if at least on the respective railing post in addition to the described fastening device for the railing rod a holder is provided which forms at least one bow-shaped carrying handle, a longitudinal plug-in receptacle for a strip profile free of perforations or the like.

The railing post expediently has on its outer outside, which is remote from its clamping arm or its clamping arms, at least one bracket, which is fastened to the outside by welding or the like with the ends of its superimposed bracket legs. If a bracket is provided directly adjacent to the upper end and a bracket is located directly adjacent to the top of the fastening device for the structural fastening, then the barrier strips can be held both at a relatively high height and near the floor or step level simply by pushing them into adjacent railing posts. The fastening device for fastening the structure and the fastening device for the railing rods are expediently located on the same inner outside of the railing post.

According to a preferred feature of the invention, a releasable connection of the mutually facing ends of railing rods is also proposed, which connect to one another in the longitudinal direction either in alignment or, for example at an angle, offset with respect to one another. This connection is expediently designed in such a way that the adjoining railing rods can be connected to one another both in alignment and in at least one angular position, the connection in the manner of an articulated connection expediently allowing a stepless angle adjustment. This allows, for example, railings to be created with railing rods that have railing rods that run at an angle in accordance with the course of stair sections and intermediate platforms.

In the case of a railing of the type described, means can also be provided according to the invention in order to be able to clamp one or more railing posts in their installed position via an adjusting device in such a way that the tensioning torque can be determined sensitively and precisely. If the actuating device as a whole is permanently stored on the railing post, all parts of the tensioning device are designed to be captive. Furthermore, the use of an actuating device makes it possible to provide the actuating member relatively far away from the actual clamping area of the railing post or at such a location at which it is particularly easily accessible for actuation. This point can be offset on the side of the railing post facing away from the tensioning area and / or in the vertical direction with respect to the tensioning area and takes up practically the same position in relation to the railing post or the post body in every actuation position, preferably at the upper end of the railing post.

Due to the design according to the invention, the actuator can also be designed so that it can be operated by turning, so that e.g. the tightening torque of the clamping device can be precisely determined with a torque wrench. If the actuating forces are to be significantly lower than the clamping forces, a reduction gear can be provided between the actuating element and the clamping element, e.g. by a spindle drive and / or a handlebar drive and / or a wedge reduction or the like. formed and can be formed in one or more stages.

The design according to the invention is suitable for external tension, in which e.g. the railing post has a type of clamp, the gripper arms of which are brought closer together for bracing and thereby e.g. can be braced from above and below against a staircase or on both sides laterally against the side surfaces of a wall.

A particularly advantageous further development also results if the tensioning device is designed instead or in addition to the internal tensioning, so that it e.g. can be clamped in the manner of an at least partially expandable inner collet against the inner surfaces of an opening on the building side. The collet can form a peg-like continuation of the lower end of the railing post or, depending on the structural requirements, project transversely from the railing post in the manner of an angle leg.

So that work can be carried out on the building unhindered, which extends laterally beyond a building boundary assigned or opposite the respective railing post, it is particularly advantageous if means are provided which enable the railing post to be arranged at a corresponding distance from this building boundary. This allows this work to be done without prior removal of the temporary railing. For example, when building a staircase, step plates must often be installed that extend laterally on the side belonging to the railing beyond the associated limitation of the stairway body, which is made of concrete, for example, before the railing was attached. In particular, if the fastening device for the internal tension is designed such that the makeshift railing has no components in the area of the treads of the steps, the respective railing post can be spaced apart from the associated lateral boundary of the tread surface by these means be arranged at the respective stair step in such a way that there are no components of the railing beyond the area delimitation, but that there is free space for the attachment of structural parts. It is particularly advantageous if the distance is between approximately 40 and 100 mm, preferably at least approximately 70 mm.

A particularly advantageous development of the subject matter of the invention is that the tensioning device and / or the actuating device is arranged essentially within the at least partially hollow railing post, which thus directly forms with its wall a housing for the protected accommodation of the corresponding components. The guidance of the adjustable tendon relative to the post body can also be substantially protected within the post body e.g. characterized in that a telescopic guide is provided, of which the telescopic outer part is expediently formed by the tubular post body.

The object on which the invention is based can advantageously be achieved in a railing of the type described or another type in that at least one clamping surface of at least one tendon in at least one a movement that is independent of the tensioning movement is adjustable, so that, for example, the inclinations of two opposing or facing clamping surfaces can be mutually changed to adapt to correspondingly inclined surfaces of the building.

In order to ensure that the tensioning surfaces of the fastening device of a railing post are as free of play as possible, even in the presence of relatively large unevenness, means are advantageously provided which, due to smaller tensioning surfaces compared to the respective entire tensioning field and / or slightly elastic compliance of these tensioning surfaces, enable a play-free adaptation to such unevenness o . Like. guarantee. For example, each clamping surface can be formed by two clamping surface areas lying parallel to one another and approximately at right angles to the railing post. Individual clamping surface areas can also be resiliently changeable in relation to one another and / or with respect to the railing post within small limits and under very high spring force. In a preferred embodiment, the clamping surface areas of the respective clamping arm are provided on edges of a profile which deviates from the planar shape in cross section, the profile advantageously being approximately rectangular to obtuse V-shaped with profile legs of equal length. If the clamping surface areas are spaced apart from each other on the two opposing clamping arms, they can be at different or equal distances from each other on the two clamping arms and in particular be arranged such that two clamping surface areas are located directly opposite each other in the direction of the clamping force. The slightly resilient V-profile ensures a very steep spring characteristic.

Another expedient embodiment of the subject matter of the invention is that the respective tension arm with its inner end facing away from the free end on an end face of a rod-shaped component of the railing post, e.g. of the telescopic outer tube or of the telescopic inner tube is fastened in such a way that its inner end surface is essentially flush with the outside of this component facing away from its free end and is continuously linear in its side view over its length. The end surface of the rod-shaped component is advantageously corresponding to the engagement surface of the profile, e.g. Profiled in a V-shape, so that there is a full-surface contact, which, however, does not have to extend over the entire profile height of the profile arm, in particular if its clamping surface regions have a lateral distance from one another which is greater than the associated outer width of the rod-shaped component of the railing post. In the case of attachment of the profile to the end face of the telescopic outer tube, the profile expediently has a through opening for the telescopic inner tube so that it is penetrated by it, but can nevertheless be connected to the outer tube with weld seams over the entire circumference of the wall.

In a further embodiment of the invention, in particular in the case of a railing post which is to be fastened with at least one arm projecting transversely, means are provided so that the protruding corner between this arm and the railing post at least on the upper side of the arm or over its entire circumference of components, such as stiffening struts, is completely free. In the event of an external tension, such struts on the upper tension arm can lead to accident hazards due to stumbling of people, while in the case of internal tension they should at most only protrude beyond the associated outside of the railing post by an amount that corresponds to the distance described, so that the tension pin is deep enough without hindrance into the building can be sunk. So that such stiffening means can be dispensed with, the tensioning arm, for example as a profile arm, is designed to be so stiff that it does not yield, or only insignificantly, yields under the loads occurring during tensioning.

Furthermore, the object on which the invention is based can be achieved in an advantageous manner in a railing of the type described or in another type by providing at least one counter-member separate from the railing or the railing post for receiving the fastening device, which e.g. can be set in concrete at the appropriate place on the structure before attaching the railing. This counter member can be designed so that it or the like both for receiving the provisional railing and, after its removal, for fastening the railing to be finally attached to the structure. suitable is.

The counterpart, particularly in the case of internal tension, is expediently designed as a receiving sleeve made of steel, plastic or a similarly suitable material. This sleeve has in the inner and / or at its outer end, e.g. on a flange plate connected to it and projecting beyond its outer circumference, connection surfaces, such as welding surfaces, for rigid connection to a railing post. At least a part of these connection surfaces, which are expediently formed by inner surfaces of the sleeve shell, are optionally also designed for a releasable connection to the railing post, preferably as a substantially flat or in longitudinal section through the sleeve, essentially straight clamping surfaces.

So that the railing post can be precisely adjusted, in particular laterally with respect to the building, and can then be secured with no play in any adjustment position, it is advantageous if the connection between the temporary railing post and the receiving sleeve is only non-positively. Advantageously, the sleeve shell of the receiving sleeve is substantially free of breakthroughs over its length or over its circumference, so that continuous clamping surfaces result approximately over the entire length of the sleeve shell. Instead of or in addition to this, a sealing cover made of another suitable material, for example plastic, can be attached to the inner end of the sleeve shell, for example formed by a tube section, through which penetration of concrete into the sleeve shell can be completely ruled out. This cover can be attached and secured in a particularly simple manner by means of a plug connection parallel to the sleeve casing, the cover being placed on the outer circumference of the sleeve casing or being inserted into it such that the cover does not protrude beyond the outer circumference of the sleeve casing.

The railing 1 according to Fig. 1 can e.g. be assembled from a multi-part kit, which has a plurality of approximately the same railing posts 2 and railing longitudinal runs, namely railing rods 3, which are releasably attached to the post 2 after assembly on the building. Each railing post 2 has e.g. in the region of its lower end there is an expediently essentially vertically tensioning fastening device 4, while 2 fastening means are provided for fastening the railing rod 3 to the respective railing post, namely one fastening device 5 each.

The respective railing post 2 has a hollow post body 6 that extends over most of its length or height and essentially up to its upper end, which is expediently formed by a section of a profiled tube, such as a square square tube. In the region of the lower end, a telescopic guide 7 is provided on the post body 6, the outer tube of which is formed by the lower end section of the post body 6 and the telescopic inner rod 8 protrudes from the lower end of the post body 6. The inner rod 8 is also expediently formed by a profile tube, the cross sections of which have the same basic shape as the outer tube.

The fastening device 4 is essentially designed as a clamp 9, which, with an actuating device 10 lying essentially within the post body 6 or the telescopic guide 7, extends over its entire travel range With the help of a single actuator 11 to close or open. The actuating device 10 has a substantially freely downwardly projecting from the upper end of the post body 6, lying in the axis of the post body 6, threaded spindle 12 which engages in a spindle nut 13 fastened to the upper end of the inner rod 8 so that part of it Length is within the inner rod 8. The upper end of the spindle 12 is mounted with an axial bearing 14 located within the upper end of the post body 6 in such a way that the spindle 12, including the actuating member 11, is axially secured to the post body 6 in both opposite directions. For this purpose, a bearing bush 15 is inserted into an upper end plate of the post body 6, which lies with an upper ring collar on the upper side of the end plate and whose lower end face is opposite a bearing ring 16 fastened to the outer circumference of the spindle 12 or a similar axial securing member. The upper end of the spindle 12 merges into the actuating member 11, which has an enlarged cross section and which, with its associated end face, lies axially secured on the collar of the bearing bush 15. In the exemplary embodiment shown, the actuator 11 is formed by an external hexagon lying in the axis of the spindle 12.

The clamping clamp 9 has a lower clamping member 17, which is movable in the clamping direction with respect to the post body 6, and a clamping jaw 18 opposite it, which is arranged in a rigid position relative to the post body 6. The clamp 9 is used to brace against the bottom and top of a dash-dotted building part 19, for example, by stairs, a floor slab or the like. can be formed. The spindle drive forms a reduction drive 20 during tensioning and loosening, so that high tensioning forces can be applied effortlessly.

To form the tendon 17, a cross arm 21 is fastened in the region of the lower end on an outer side of the inner rod 8 in such a way that it lies essentially symmetrically to the central plane of this outer side and at right angles to the post body 6. The cross arm 21 is expediently formed by a tube section with rectangular cross sections, the greater edge length of which is approximately parallel to the post body 6 and whose side faces are approximately aligned with the associated side faces of the inner rod 8. To form the clamping jaw 18, a plate-shaped cross leg 22 is fastened on the same outside, but on the post body 6, at a short distance above its lower end, the leg width of which is expediently substantially larger than that of the cross arm 21 or as the outer width of the post body 6, so that the cross leg 22 protrudes laterally beyond the post body 6 on both sides. The cross leg 22 can be formed by an angle leg of an angle plate, which is attached with its other, upwardly protruding angle leg to the associated outside of the post body 6 and whose legs are braced against each other. The face of the cross member 22 facing the tendon 17 forms the associated, essentially flat clamping surface 24, which can also protrude in the longitudinal direction of the cross leg 22 over the tendon 17, so that it forms a kind of standing surface, which is secure even when the clamp 9 is not closed Stand of the railing post 2 on the building part 19, for example guaranteed for the purpose of alignment.

The clamping surface 23 of the clamping member 17 has a substantially smaller total area than the clamping surface 24 and is expediently divided into at least two individual surfaces, each of which is provided on a pressure piece 25 at a distance above the cross arm 21. Each individual surface of the clamping surface 23 is formed by the T-crosspiece of a T-shaped pressure piece 25, which with the lower end of its T-footpiece is pivoted freely in a bearing 26 of the cross arm 21. The bearing axes of the pressure pieces 25 are expediently parallel or in alignment with one another and at right angles to the post body 6 or parallel to the cross arm 21 in an axial plane of the post body 6 or the cross arm 21. The fork-shaped bearings 26 are fastened to the top of the cross arm 21 and each have two bearing cheeks lying on both sides of the associated pressure piece 25, wherein a bearing cheek of a bearing 26 can simultaneously form an outer end plate of the cross arm 21. The two pressure pieces 25 are spaced apart in the longitudinal direction of the cross arm 21.

To assemble the railing post 2, it is plugged approximately horizontally onto the building part 19 when the fastening device 4 is open, until that outside of the post body 6, over which the clamping arms of the clamping clamp 9 project, strikes the associated edge of the building part 19. In this respect, the lower end of the post body 6 below the clamping surface 24 forms a stop 27, by means of which the inner part 8 prevents the structural part 19 from touching. Then, with the aid of a wrench, the actuating member 11 is rotated, as a result of which the lower clamping surfaces 23 are raised relative to the post body 6, without the post body 6 even having to perform a vertical movement relative to the structural part 9. The clamping clamp 9 is then braced with a predetermined torque in relation to the building part 19. At the latest afterwards, but possibly also before the final bracing with respect to the structural part 19, at least one railing rod 3 is fastened with the fastening device 5 on the outside of the post body 6, via which the clamping clamp 9 also projects. Two or three fastening devices 5 or railing rods 3 lying one above the other at a distance are expedient provided, the uppermost of which protrudes beyond the upper end of the post body 6 and possibly the actuator 11 and forms a handrail.

In the embodiment according to FIG. 2, the fastening device 4a is designed in the manner of a mandrel 9a for internal clamping such that the clamping surfaces 23a, 24a are moved away from one another during the clamping. For this purpose, a single, housing-like hollow cross arm 21a is fastened in the region of the lower end of the post body 6a and serves as a plug-in pin for insertion into a hollow counter member 18a adapted to it. This counter member 18a is on the structural part 19a e.g. to be fixed by embedding and essentially consists of a tube section 22a of larger, but approximately the same cross-section as the mandrel 9a and a flange plate 28 attached to the outer end and one at the inner end e.g. plastic plug or the like fastened closure cover 29. The counter member 18a is expediently embedded in the structural part 19a in such a way that the flange plate 28 is flush with an upright edge surface of the structural part 19a. 28 through holes for nails or the like are expedient in the flange plate. Provided with which the counter member 18a can be attached to the inside of the formwork used to manufacture the structural part 19a.

The tendon 17a lying essentially within the transverse arm 21a is expediently designed in the manner of a two-armed lever, the arm of which lies closer to the free end of the transverse arm 21a with an area essentially formed by a longitudinal side of the lever slightly upwards over the outer or upper side of the transverse arm 21a protrudes and forms with this area the convexly curved clamping surface 23a in side view. This area of the tendon 17a, which extends approximately over the entire associated inner width of the cross arm 21a, projects through a window opening 31 which is provided in the upper wall of the cross arm 21a and closely adjacent to its free end closed with an end plate.

The tensioning member 17a is connected to the spindle drive located inside the post body 6a via a link drive 30 which lies essentially within the transverse arm 21a. The spindle nut 13a carries a bearing fork 32 at a distance below the spindle 12a, with which the one end of a two-armed arm 33, which extends approximately in the longitudinal direction of the transverse arm 21a, is connected in an articulated manner. The articulated connection is made by means of a hinge pin 34 engaging in at least one elongated hole. Approximately in the middle between its ends, the link 33 is pivotably mounted within the cross arm 21a with a bearing 35 on the cross arm 21a. The arm of the link 33 facing away from the post body 6a is connected in an articulated manner to the arm of the tensioning member 17a facing away from the clamping surface 23a, this joint also being formed by a pivot pin 36 engaging in at least one elongated hole. This arm of the tension member 17a is expediently designed as an articulated fork, between the fork cheeks of which the handlebar 33 engages. The tensioning member 17a is mounted on the cross arm 21a with a bearing bolt 7a passing through it. All bearing and joint axes are essentially parallel to one another and at right angles to the common central plane of the post body 6a and the cross arm 21a.

If the actuator 11a is rotated so that the spindle nut 13a moves downward, the clamping surface 23a is withdrawn into the cross arm 21a. When the spindle nut 13a moves upward, the clamping surface 23a rests on the upper inner surface of the counter member 18a, while the lower outer side of the cross arm 21a facing away from it forms the second clamping surface 24a, which braces against the lower inner surface of the counter member 18a. The handlebar drive 30 can be designed so that it also forms a reduction drive, so that a two-stage reduction drive is provided between the actuator 11a and the tension member 17a.

The fastening device 4a is designed such that between the inner outer surface 27a of the railing post 2a and the opposite side surface of the structural part 19a or the outer end of the counter member 18a or the flange plate 28, a distance can be set within relatively large limits, which is expedient in the Order of magnitude of 70 mm. As a result, even when the railing post 2a is mounted rigidly in position, such work in the area of the tread surface of the building part 19a that extends laterally beyond this building part 19a is not impeded. The protruding angle between the inner outer surface of the railing post 2a and the upper longitudinal surface of the mandrel 9a is of struts or the like. free, so that a gap extending up to the top of the mandrel 9a remains free between the side surface of the structural part 19a and the outer surface 27a.

After releasing and removing the railing post 2a, the counter member 18a remains on the structure, so that it is suitable for attaching to it the railing post of a final railing, e.g. to be fixed by casting or also releasably. Otherwise, the same reference numerals are used in FIGS. 1 to 4 and 7, 8 for corresponding parts, but with different letter indices, which is why the corresponding description parts apply to all figures.

The fastening device 4b according to FIG. 3 is also essentially designed for the internal clamping as a mandrel in the manner of an internal collet 9b. For this purpose, the cross arm 21b is laterally on both opposite sides slotted longitudinally so that there are two pliers arms 25b which project substantially over most of their length and are U-shaped in cross-section, which lie one above the other and form clamping surfaces 23b with the outer sides of their U-cross legs facing away from one another. A wedge piece is fastened in each of these clamping arms 25b in such a way that the wedge surfaces facing one another diverge in the direction of the free end of the transverse arm 21b. An internal clamping wedge 8b with corresponding wedge surfaces is guided on the wedge surfaces 7b. The clamping wedge 8b has an internal thread 13b which lies essentially in the central axis of the transverse arm 21b and into which the spindle 12b is screwed. The spindle 12b lying parallel or coaxial to the transverse arm 21b lies with most of its length within the transverse arm 21b and passes transversely through the lower end of the post body 6b, in such a way that it is guided outwards on the outside thereof facing away from the transverse arm 21b this outside carries the actuator 11b. With the spindle 12b secured in the axial bearing 14b, the cross arm 21b can be spread and narrowed again in a resilient manner, the cross arm 21b being expediently assigned to a counter member similar to that according to FIG. 2.

In the embodiment according to FIG. 4, the clamping direction of the fastening device 4c or the clamping clamp is provided horizontally or at right angles to the post body 6c, the lower end of which directly forms a clamping jaw 18c such that the outer surface of the post body 6c facing the other clamping member 17c serves as the clamping surface 24c is provided. Above the clamping surface 24c there is a telescopic guide 7c at right angles to the outside of the post body 6c, the outer tube of which is fixed in position on the post body 6c. The telescopic inner rod 8c carries the associated tensioning member 17c lying at an angle to it, which is provided in the region of its free end with a tensioning surface 23c projecting beyond its inside. The 3 is perpendicular to the post body 6c, and the actuating member 11c is provided on the outside of the post body 6c facing away from the movable tensioning member 17c. This railing post 2c is used in particular for fastening to the top of upright walls, such as retaining walls or the like, which can occur, for example, in road construction.

According to Figures 1, 2 and 5 to 6, the respective railing rod 3 is expediently composed of two or three telescopically displaceable metal profiles 37, 38, 39, which are approximately rectangular C-shaped in cross section. Each metal profile has a row of holes of long-round plug-in holes 41, which are symmetrical to its associated central plane and extend essentially over its entire length, in the crosspiece of the profile, the longitudinal extension of which is perpendicular to the metal profile and the approximately equal distances from one another and with all metal profiles 37, 38, 39 have, so that the plug-in holes of inserted metal profiles can be substantially congruent. It is also conceivable to select the hole spacing in the individual metal profiles slightly differently, in order to enable an adjustment that is finer than the hole spacing to the extent that plug-in holes are congruent with each other in each adjustment stage.

The plug holes 41 are adapted to plug pins 40 of the railing posts 2. Each railing post 2 or its post body 6 has, on the side on which the fastening device projects, two or more such spigots 40 one above the other at a distance in each case at the height at which a railing rod is to be attached. The respective plug pin 40, which is rectangular in cross-section and which can also be pivoted about an axis which is approximately perpendicular to the railing post 2 in order to adapt to any inclined positions of the railing rod, is a component of the associated fastening device 5. It serves to receive a flat clamping wedge 42 penetrating it on its flat sides and penetrating a wedge opening 43 of the plug pin 40. This clamping wedge 42, which is approximately parallel in the assembly position to the railing rod, is supported with an oblique wedge surface formed by a narrow edge on the boundary of the wedge opening 43 facing away from the railing post 2 and has one for by the system on the inside of the profile crossbar of the associated metal profile Edge surface formed wedge surface, which rests essentially over the entire surface on this inside of the crossbar.

At its tapered end, the clamping wedge 42 is provided with a securing element 44 which is enlarged compared to the wedge opening 43 and is formed, for example, by a spherical head, which secures the clamping wedge 42 against being able to be completely removed from the plug pin 40. When the securing member 44 rests on the associated side surface of the plug pin 40, the clamping wedge 42 can be aligned approximately parallel to the plug pin 40 by pivoting. The dimensions are provided in such a way that the clamping wedge 42 with the plug pin 40 can then be inserted into or pulled out of a plug opening 41. The plug pin 40 and the clamping wedge 42 and thus the entire fastening device 5 are essentially completely within the railing rod 3 or the associated metal profile in the tensioned state.

If two or more metal profiles inserted into one another are provided in the area of the respective railing post 2, the plug pin 40 passes through plug holes 41 in all metal profiles, as a result of which these are secured or locked in position in the longitudinal direction of the railing rod 3. In this respect, the fastening device 5 simultaneously forms a locking mechanism between the metal profiles 37, 38, 39.

It is also conceivable to secure the metal profiles against one another by means of separate securing members, such as bolts, which are at a distance from the respective railing post 2 and which then pass through congruent plug-in holes 41. The outside of the crossbar of the largest metal profile 37 is stretched directly against the associated flat outside of the railing post 2 by the fastening device 5.

An angle connection 45, which can be designed as an adjustable joint connection, is expediently provided to connect sections of the longitudinal runs or railing rods 3 which are to be angled in the side view according to FIG. 5 and / or in the top view according to FIG. 6. and also forms clamping devices. In the illustrated embodiment, the angle connection 45 is provided to connect the sections of the railing rod 3 such that they are either aligned in side view or at an angle to one another in a side view, wherein the sections can be angularly adjusted in opposite directions from one another in the aligned position.

At the end of the smallest or innermost metal profile 39 of a section of the railing rod 3, at least one connecting plate 46 is fastened for this purpose, a connecting plate 46 being expediently fastened in each case on the inside and on the outside of the profile crosspiece such that the two essentially congruent and at a small distance parallel to each other connecting plates 46 protrude freely over the end of this metal profile 39. The connecting plates 46 engage in the end of a corresponding metal profile 39 of the other railing rod section and are connected to this via a hinge 47, the hinge axis of which is substantially perpendicular to the longitudinal direction of the railing rod 3 and approximately horizontally in the longitudinal central plane of the associated railing rod section .

In the exemplary embodiment shown, the two connecting plates 46 rest in the region of the joint 47 on the inside and on the outside of the profile crossbar of the associated metal profile in the manner of clamping claws. Both connecting plates 46 and the associated profile crossbar are penetrated by two bolts 49 which are spaced apart from one another transversely to the longitudinal center plane of the associated metal profile 39. These bolts 49 penetrate elongated holes 48 in the connecting plates 46 or in the cross-piece of the profile, which essentially extend around the articulated axis or are approximately at such an angle at an acute angle, the bolts 49 engaging in the elongated holes 48 with a corresponding transverse play . By tightening the bolts 49, e.g. The hinge 47 is fixed in the set position by bolts with nuts or by screws screwed into the profile. The maximum limited swivel angle can be changed by appropriate angular position and / or curvature of the elongated holes. The distance between the two screws enables secure clamping with a large lever arm. By loosening the bolts 49, the angle connection 45 can also be released. Furthermore, it is conceivable to provide joints 47 in the area of both mutually adjoining metal profiles 39. Due to the design described, the angle connection 45 can lie essentially completely within the metal profiles 39 which are connected to one another.

At least the two larger metal profiles 37, 38 can each have a length of approximately 2 m, while the smallest metal profile 39, on the other hand, is expediently shorter. The metal profiles 37, 38, 39 are preferably made of aluminum. But plastic profiles are also conceivable.

In the embodiment according to FIGS. 7 and 8, each tensioning arm 17d, 18d is formed by a V-profile 21d or 22d, which is expediently made by bending a sheet metal strip accordingly is made. Both sheet metal profiles can be of the same design and are each attached to the post body 2d in the manner of an arm which projects freely over its entire length. The upper tension arm 18d is fixed to the lower end surface of the post body 6d or the telescopic outer tube by welding so that it extends to the outer outer surface thereof. Accordingly, the lower tension arm 17d is fixed to the lower end surface of the telescopic inner rod 8d. The upper clamping arm 18d is free of additional stiffening struts, such as are shown in FIG. 1, in this case, so that it has a slightly greater bending elasticity than the lower clamping arm 17d. This lower clamping arm 17d is reinforced with an additional, angular stiffening, which is fastened by welding with a shorter leg on the outer outer surface of the telescopic inner rod 8d and with a longer angle leg on the underside of the clamping arm 17d facing away from the associated clamping surface 23d, and also in the form of a web and is narrower than both the inner rod 8d and the tension arm 17d.

The lower end face of the post body 6d is provided with a V-shaped groove adapted to the profile of the tensioning arm 18d, so that the respective profile leg of the tensioning arm 18d connects in cross section at an obtuse angle to the associated outer surface of the post body 6d and projects laterally beyond this outer surface. The associated end of the tensioning arm 18d is provided with a through opening which is adapted to the inner cross sections of the post body 6d and is penetrated by the inner rod 8d. The lower end of this inner rod 8d is adapted by V-shaped tapering to the inner cross section of the clamping arm 17d, which extends to the outer outer surface of the inner rod 8d or to the associated leg of the stiffening angle 52 and whose profile leg also laterally on both sides via the inner rod 8d protrude.

The profile legs of the two clamping arms 17d, 18d are directed towards one another and each form clamping area regions 23d, 24d with an edge of each edge surface. The clamping surface areas 23d, 24d of each clamping arm 17d or 18d are parallel to one another at a distance from one another which is greater than the thickness of the railing post 2d, but two clamping surface areas 23d, 24d each parallel to the longitudinal direction of the railing post 2s Opposite direction. This results in a very precisely defined contact of the tension arms 17d, 18d on the associated surfaces of the building part 19d.

As FIGS. 7 and 8 further show, a holder 50 is provided on the outer outside of the post body 6d of the railing post 2d, which e.g. is formed by three identical brackets 51 lying one above the other at equal intervals and which are narrower than the associated outer side of the post body 6d. Each bracket 51 is fastened with the end faces of its bracket legs to the aforementioned outer side of the post body 6d by welding, the upper bracket leg of the uppermost bracket 51 expediently directly adjoining the upper end of the post body 6d and the lower bracket leg of the lowest bracket 51 closely adjacent to the lower one End surface of this post body 6d is. 7 with the post body 6d delimits a flat rectangular bracket or passage opening, the larger cross-sectional extent of which lies in the height direction of the railing post 2d and the cross-sectional extent transverse to the longitudinal direction of the post is selected approximately in the order of magnitude of the post thickness.

9 and 10 show a railing post 6b, which consists of a round or square tube, in the lower end of which a flange 50 is welded in the form of a square plate. An elongated, rectangular slot 51 is provided in the plate and on the underside of the A pipe section is welded onto the flange, which forms the fastening device 4b, which, like that according to FIG. 3, is designed as an internal collet 9b. For this purpose, the round tube piece is tapered and slotted towards its lower end, so that two tong arms 25b with a semicircular shell profile are formed, which are separated from one another by the slot 53. A clamping part 8b can be driven into the interior of the forceps arms, which extends through the entire railing post 6b up to its upper end 54 and has an elongated, rectangular cross section corresponding to the opening 51 which guides it. A cross pin 55 is inserted near the lower end so that the rod-shaped clamping part cannot be pulled out upwards because the pin locks on the flange 50. In Fig. 9, the taper is exaggerated for better illustration.

A larger hole 56 is provided in the upper end of the clamping part, into which a tool, for example the pick of a mason hammer, can engage in order to pull out the clamping part.

The plug pin 9b of the fastening device 4b can be inserted into a hole 57 drilled, for example, in a concrete slab and fastened by hammering in the clamping part 8b from above, the pliers arms 25b spreading apart with transverse movement when the clamping part penetrates into the interior between the pliers arms. It has been shown that an expansion up to approximately the cylindrical shape is usually sufficient for fixing. If this is not the case and further anchoring is desired, for example on less solid ground, e.g. in road construction, the spreading can also extend beyond the cylindrical shape, for example by the pliers arms 25b with beads 60 indicated by dash-dotted lines that widen downwards , are provided and / or by bending the edges of the slot 53 additional gripping surfaces are created that could also be designed like barbs, for example. This creates a railing post that is particularly simple and easy to insert into existing holes or holes in any material. It also has one of the main advantages of the invention, namely the large assembly time savings with great reliability and stability of an emergency railing and the material savings due to the practically unlimited reusability.
