Description

The The invention relates to a wall anchoring auxiliary device made of metal for vertical and Horizontal support structure formed scaffolding, consoles, grandstands Ladders or the like. With a fastened to the support structure elements tubular support arm and one firmly connected to it by means of welding, in one Wandverankerungsöse be suspended Anchoring member.

Staff structure-bearing structures, like scaffolding, Consoles, grandstands, Ladders or the like are with vertical and horizontal support structure elements educated. The also with vertical or horizontal stems designated Supporting structural elements are usually designed as round rods or round tubes, wherein for the application of coverings Horizontal support bar can be provided. Using such Supporting structure elements can Bar structure structures great Height created become. These are for safety against swinging and secure against falling over.

In many cases are bar-structure structures, such as scaffolding, not freestanding built, but be in the vicinity of buildings, for example on the outer walls of Buildings, situated. It is due to the inherent in the building or the building Load capacity to anchor the bar structure structures there in a suitable manner.

to Fixing of scaffolding become common at certain points of the structure at certain intervals attached wall anchoring loops, which are usually in suitable openings or Holes introduced wall anchoring dowels are screwed. to Anchoring rod-structure structures such as scaffolding are auxiliary devices according to the generic term of claim 1 known. These are for example with a straight Pipe section formed with perpendicular to the tube longitudinal axis formed ring end faces. To make a secure connection to the scaffolding, the pipe section be fastened to the support structure elements in a suitable manner. You can do this For example, coupling elements, such as screw-on pipe couplings be used.

Around also lateral forces securely supported or transmitted to be able to is suitably one screwed on variable positions clamp coupling for mounting on the vertical stems and one on the respective constructive Conditions adapted designed Intervention or Attack element provided in the region of one end of the pipe section, For example, from the bottom of the horizontal support bars on or can intervene. Alternatively you can longer Pipes to be provided in conjunction with two clamp couplings, the can each be attached to adjacent vertical stems.

in the Region of the other end of the metal tube is on the outer circumferential surface a in the contact area parallel to the pipe axis extending circular cylindrical Rod welded. This points in a matched to the wall anchoring eyelet distance from Front end of the tube a bend of greater than or equal to 90 ° in the direction on the front end of the pipe. This is a hook-shaped anchoring member formed, which is suspended from above in the wall anchoring eyelet.

Such a wall anchoring auxiliary device is for example from the DE 27 21 870 A1 known.

The hooked Anchoring links become predominant made in the way that on the planned total length cut straight cylinder rods made of metal in a suitable heating device, for example, an oven at elevated temperatures over a be stored for a certain period of time until they reach the desired, followed by a heat-form bending process have reached the required temperature. To ensure that the anchor hook the desired or required material properties even after the hot-bending process maintains or receives, it is necessary that the Warm bending process in a specific period of time after removal the preheated cylinder rods out of the oven. Dependent on from the chosen ones However, manufacturing process can not be ruled out that between the removal from the oven and the subsequent hot-bending process to time delays comes. In these cases it can happen that the cylinder rods too low a temperature for have the warm bending process, whereby it during the forming of the same too unwanted Material or surface effects come can. It is possible do not rule out that such produced suspension hook do not meet the required safety requirements.

Thus, the forces occurring in rod structure structures such as scaffolding can be safely introduced via the holding tube and the hook-shaped anchoring member in the wall anchoring eyelet and from there into the masonry, the load situation must also be considered in the connection area between hook and holding tube. For this purpose, the wall anchoring eyelet must be positioned relative to the holding tube in a suitable manner, it has been shown that expediently the eye longitudinal axis, ie the axis through the center of the eyelet, normal to the plane defined by the eyelet, in the plane formed by the longitudinal axis of the holding tube and the axis of the part of the anchoring element to be suspended in the wall anchoring eyelet. Furthermore, the plane spanned by the eyelet as possible cut the tube, that lie approximately within the diameter range of the holding tube.

Another device for attaching a scaffold to a building wall with the features of the preamble of claim 1 is known from DE 73 41 048 U known. This comprises one or more holders of a tubular support member whose wall-side ends may be flattened. On the latter, a bar iron may be welded at a right angle to the holder. However, the transferable in the connecting region between the bar iron and the holder anchoring forces are limited and the support and power transmission ratios to the wall-side coupling part are unfavorable.

Of the Invention is based on the object, a wall anchoring auxiliary device of the type mentioned above, in which using a deformation-free manufacturable anchoring member secure transmission the anchoring forces occurring in rod-structure structures easy weldability allows becomes.

These The object is solved by the features of claim 1.

The fact that the holding arm is formed in the region of the anchoring member with a stiffening profile which securely receives the anchoring forces and enables a secure connection to an anchoring member which can be produced without deforming,
a secure anchoring of the bar-structure structures is made possible, with a favorable force attack on the wall anchoring eyelet with advantageous weld formation a tensile, compressive and lateral forces safely transferable device is made possible in the security risk due to improper transformation can be excluded in the production of the anchoring member.

Thereby, that the stiffening profile with a in the interior of the tubular Haltearmes directed deformation is formed, further improved rigidity ratios and especially cheap Support and force transmission conditions by creating open spaces for the Wall anchoring eyelet allows.

advantageously, is the stiffening profile with a double wall areas forming crimping or press deformation formed of the holding arm. This carries in a special way while maintaining or creating cheaper Material conditions for Stiffening of the stiffening profile, whereby also favorable accessibility and investment conditions in terms of the weldability are possible.

Conveniently, is the anchoring member with a substantially straight circular cylindrical Anchor rod made of metal. This makes it possible to produce a deformation-free Anchoring member to be used, which can be easily and safely suspended in the wall anchoring eyelet.

advantageously, is the stiffening profile with a safe and easy weldability enabling Formed end profile, which expediently conically in the direction of the anchoring member tapered wall parts having.

From Another advantage is when the anchoring member in a Angle less than 90 ° to the longitudinal axis the holding arm is arranged. This is after hanging the Anchoring element in the wall anchoring eyelet with subsequent horizontal Alignment and attachment of the support arm to the bar structure support structure the auxiliary device out with little play and against lifting from the Anchoring eyelet secured.

The the above measures carry both individually and in combination with each other as also in combination with the features of claim 1 to a secure transmission the forces occurring in rod-structure structures and thus to a safe Anchoring the bar structure structures at.

Further Details, advantages, features and aspects of the invention are also discussed in the following, with reference to the drawings Description part shown.

One embodiment is described in more detail below with reference to the drawings.

3 an enlarged partial longitudinal cross section of the auxiliary device according to 1 , without representation of the wall anchoring eyelet.

The wall anchorage auxiliary device 20 Show this with the anchor rod 25 formed anchoring member and the support arm 34 on. The holding arm 34 is with the substantially circular cylindrical tube 35 made of plastically deformable metal, in particular made of steel.

The pipe 35 has a tuned to the respective mounting conditions length 36 and an outer diameter over most of its length 37 as well as a constant wall thickness here 38 on. The outer diameter 37 and the wall thickness 38 are designed taking into account the respective material conditions to the attacking or transmitted forces or moments.

In the area of the anchor rod 25 associated end 41 of the pipe 35 differs from the otherwise constant circular cylindrical shape. As in particular from the 1 and 3 shows, is the pipe 35 in the area, the free end 26 the anchor rod 25 opposite, inward towards the fixed end 27 the anchor rod 25 deformed designed, wherein the outer diameter 37 assigned wall part 42 at a distance 43 from the end 41 of the pipe 35 kink-free in the inwardly extending wall part 44 passes. This runs in the, in particular in 3 represented, through the tube axis 46 and the bar axis 28 clamped cutting plane first in an inwardly curved arc. This curvature increases up to approximately at the point of intersection with the tube axis 46 lying inflection point 45 then into the outwardly curved wall part 47 move. The end 48 of the wall part 47 ends at a small distance 49 from the inner circumferential surface 39 of the pipe 35 , To allow drainage of fluid media is in the wall part 47 the opening 72 provided, which is formed by the fact that the flap 73 in partial wall areas of the wall part 47 punched out and then upwards towards the end 78 of the pipe 35 is bent over.

As in particular in 2 As can be seen, the tube points 35 , due to the formed with internal deformation design that with the double wall areas 51 . 1 . 51.2 formed stiffening profile 55 on. This points towards the end 41 of the pipe 35 extending conical wall parts 56.1 . 56.2 on. These are end by the anchor rod 25 assigned, parallel to the rod axis 28 extending and lying in a common plane end faces 57.1 . 57.2 limited. As a result, they are parallel to the rod axis 28 extending boundary edges 58.1 and 58.2 educated. These have a distance 75 on, just the outside diameter 29 of the circular cylindrical anchor rod 25 equivalent. This measure is an advantageous final profile 70 created that allows easy weldability and favorable force attack or -Übertragungsverhältnisse with good weld accessibility.

The inwardly deformed designed wall part 47 is in the area of its upper end 48 with the two also parallel to the rod axis 28 extending interior wall parts 59.1 . 59.2 designed, these at least in some areas on the conical wall parts 56.1 and 56.2 inside. That's what it's made of 2 formed apparent stiffening profile, the two nested, in cross-section U-shaped wall parts 56 . 59 wherein the respective transition regions with the two, in cross-section eyelet-shaped wall parts 61.1 . 61.2 are formed. Their outward and towards the free end 26 the anchor rod 25 pointing lower boundary edges 62.1 respectively. 62.2 are in the distance 64 from the upper boundary edge 63 arranged. This is just chosen so large that the inner eyelet boundary edges 66.1 . 66.2 in the pipe axis 46 containing and normal to the rod axis 28 formed level 68 lie.

To improve the force-attack and transmission ratios is the tube 35 in which the wall part 67 forming area, shaped outward deformed. It goes the outer diameter 37 having wall part 69 at a distance 71 from the upper end 41 of the pipe 35 kink-free in the wall part 67 above. The wall part 67 runs in a slightly upward outward curvature to the end 41 , wherein the upper boundary edge 63 a radial distance 71 from the upper wall part 69 of the pipe 35 having. This is the one with the lower wall parts 65.1 and 65.2 formed bearing area for wall anchoring eyelet 40 near the tube axis 46 arranged so that a favorable force or torque conditions enabling lever arm is created. Furthermore, by the above measure, the length of the rigidity-increasing double wall portions 51.1 and 51.2 be sized sufficiently large, so that the stiffening profile 55 on the one hand has the required stiffness and on the other hand, a sufficiently large investment area to the anchor rod 25 allows the transmission of the forces acting there.

The anchor rod 25 is circular cylindrical with the outside diameter 29 trained and points in the of its length 30 corresponding distance normal to the rod axis 28 trained upper Stirnflä che 31 as well as the lower end face 32 on. Made of metal, preferably made of steel anchor rod 25 is at the end faces 57.1 and 57.2 of the pipe 35 welded, in such a way that the upper end face 31 at the upper boundary edge 63 of the pipe 35 is applied. To secure against lifting and low-play wedging is the anchor rod 25 around the angle 74 opposite the normal to the tube axis 46 in the direction of the stiffening profile 55 arranged inclined so that the anchor rod 25 at an angle smaller than 90 ° to the longitudinal axis 46 of the holding arm 34 is arranged. This inclination is advantageously due to the structural design of the stiffening profile chosen here 55 in conjunction with the circular cylindrical outer shape of the anchor rod 25 allows.

The attachment of the wall anchorage auxiliary device 20 for securely anchoring a bar-structure support structure is done in the following manner. The wall anchorage auxiliary device 20 will be with the free end 26 the anchor rod 25 ahead in the opening 76 the previously on the wall 77 attached wall anchor eyelet 40 to the plant at the lower wall parts 65.1 and 65.2 plugged in. Subsequently, the wall-anchoring auxiliary device 20 by pivoting the with the pipe 35 formed Haltearmes 34 transferred to the top in a horizontal position, so that the tube axis 46 is oriented approximately horizontally. Subsequently, by means of suitable, for example in the region of the end 78 of the pipe 35 or at one or more secure fastening enabling positions along the pipe 35 suitably designed fasteners, such as screw-on pipe couplings attached, which are firmly connected to the vertical and / or horizontal support structure elements of the bar-structure support structure.
