Abstract

The tensile strength connection device for two construction elements is particularly intended to the anchoring of support on foundations with a tie rod, which is connected to an anchoring element intended to be concreted in a concrete element. The anchoring element is comprised of a hollow body (5) closed on its contour and on its lower portion and is provided in its upper portion with a supporting element (4', 4'') provided with an opening (13) and fixed to the hollow body (5). In the area between the bottom (6) and the supporting element (4', 4'') there is arranged an anchoring plate (2) provided with a threading (14), wherein the tie rod (1) may be threaded directly through the opening (13) of the supporting element (4', 4''). The opening (13) of the supporting element (4', 4'') is larger than the cross-section of the tie rod (1) by at least the desired tolerance and the anchoring plate (2) is smaller, in the plan perpendicular to the axis of the tie rod (1), to the internal dimensions of the hollow body (5) in the plan of the plate (2), by at least the desired tolerance. The larger dimension of the plate (2) in the plan perpendicular to the axis of the tie rod (1) is bigger than the smallest internal dimension of the hollow body (5) in said plane.

Description

An apparatus for tension-proof connection of two components

The invention relates to a device for restraint connection of two elements, preferably for anchoring supports on foundations, having a tie rod which is moun- ted in a, in a concrete body einzubetonierenden anchor body.

For the tensile strength between components, such as the supports of hangars or large machine elements with the foundations are common anchoring structures, in which the tensile forces to be transmitted are transmitted by tie rods via anchor bars in the foundation body.

This anchoring structure consists essentially of two elements. The first element is the body concreted deep down in foundation anchor bars, which transmits the pulling force to be anchored by compression between the armature bars and the enveloping Be¬ ton of the foundation. The anchor bars acts as a bumper bracket and must be formed corresponding rigid to the

--- m z __? Receive L_ bending moments that occur due to the necessary bridging the distances between the location of the power allocation, which is the connection point of the drawbar to the armature bars and the points where the armature bars, in turn, transmits the force by pressure on the foundation concrete , This requires a large cost of materials for the anchor bars for both the er¬ ford variable bending stiffness as well as for the training correspondingly large pressure-transmitting surfaces. The second element is the tie rod. This must be hung down in the foundation into the anchor bars, for which purpose they usually has at its lower end a widening in the form of a hammer head.

The pull rod is thereby rotated in a slot-shaped opening through ddeenn AAnnkkeerrbbaarrrreenn hhiinndduurrcchhggeeffüühhrrtt aanndd ddaannnn uumm 90, so that the hammer head in the armature bars verhängt-

In this known anchoring construction of the anchor bars must be displaced for two reasons deep in the foundation. First, a sufficient height of the concrete above the anchor bar upstream hands must be to effect a local breaking of the concrete under the Wir¬ the upward-acting, be transmitted from the armature bars Druck¬ forces to be avoided. Secondly, the length of the tie rod has to be chosen so large that considered for the plan, the inevitable in building practice tolerances between the position of the anchor bar and the location of the building or to be anchored Maschinen¬ element by the resilience of the tension rod can be compensated , Thus, such anchors typically have depths of the armature bars of 1 Einbau¬ - 3 m below the Fundamentober¬ edge.

it is aggravating for the installation of such tying bar now that accordingly deep anchor channels advertising recessed in the foundation -3-

the need. The necessary molds are kompli¬ sheet in structure and provide in use a risk, because it must be prevented that during the concreting of the concrete foundation in the later anchor channel or into the region eindrin i. 5 in the later the drawbar wer¬ hooked into the anchor bars the intended because otherwise the tie rod with the hammer head nic can be used. To avoid this risk, such anchorages are often designed so that the anchor

welded 10 barren pipes or other hollow bodies directly wer¬ to the barren a lost circuit for holding the free Anker¬ channel or the zone of the imposition of the tie rod with the anchor represent. But that increase both the Herstel¬ development costs for anchoring construction as well as the Trans

15 portkosten, since the armature bars together with these tubes because of the large mounting depth relatively large, bulky body.

Regardless of whether the anchor bars are now hen ver with such pipes or not it is difficult to secure the anchor bars in foundations 20 ment body before concreting so well that they do not change their position during the concreting of the foundation.

Object of the invention is to avoid the disadvantages mentioned above be known per anchoring structures. Especially

25 an anchoring structure should be created which Wed. less material can be easily manufactured. Wei to the installation of the construction according to the Fun¬ dation easily and risk can be made. It is further an Kons ruktionsform found v / ground, which at a minimum

30 transport volume by interleaving several inventive anchoring structures results with each other. However, since the structure is to allow the balancing of the un¬ avoidable in building practice tolerances. This is achieved erfindungs¬ accordance characterized in that the anchor body consists of a umfangssei- tig and bottomed hollow body and in the upper region of the hollow body a provided with an opening opposing body with the hollow body is firmly connected and in Be¬ area between the base and the counter-bodies a a connection thread having anchor plate is loosely inserted, directly switched into the through opening of the counter body through which the tie rod is screwed, wherein the opening in the counter body is greater by at least a desired degree of tolerance than the durchtre¬ tend cross section of the rod and the anchor plate in the plane transverse to the axis of the draw bar at least to provide the desired To¬ leranzmaß in the hollow body is smaller than the inner dimensions of the hollow body in the plane of the anchor plate, the largest Er¬ stretching of the anchor plate in the plane transverse to the axis of the tensile rod is greater is, as the smallest inner dimension of the Hohlkör pers in the said plane. According to the invention, an anchor body is thus disposed just below the upper edge of the concrete body, the tolerances there directly to compensate for the inevitable in building practice Lage¬ between to be joined structures, Z.3. Indoor support and foundation permitted and by a direct Kraft¬ transition from the anchor body in the concrete body without the Zwischen¬ circuit of rigid anchor bars at substantially less material leads. The tie rod is then directly into the

screwed anchor body and is therefore substantially kürz.er. at the same time as well as the hammer head is avoided to a significant material and cost savings resulting rod even when the tensile. Furthermore, the erfindungsgeraäße training reduces the weight and the transport volume and the transport costs. An expedient embodiment of the invention is that are arranged on the hollow body for the direct transmission of force into the concrete anchoring elements, preferably directly on the hollow body loading strengthened anchoring rods or anchoring loops. Thus, the anchoring force will be forwarded directly to the depth of the Be¬ clay body, so that the hollow body can be arranged directly on the upper edge of the concrete body without this leading to over-stressing of the concrete. Another embodiment of the invention is that height-adjustable adjusting elements, v preferably screws are arranged on the upper side of the hollow body. It can thus a e Einjustierung times the distance between the two to a binding elements, for example, so the height position between a Hallen¬ support and carried out the foundation. In a broad embodiment of the invention it is provided that the Gegenkör is arranged by forming an overlying free space unterha the upper edge of the hollow body. Thus, the A may kerkörper for direct introduction of forces transverse to Zugstan example thus to initiate horizontal forces lenstütze between Hal¬ and foundation, be used by with no further action on Fundamentkör, said to be anchored body comprises elements which engage into this free space, creating even de casting the free space is given a direct power transfer

Since the recessed from the concrete body volume is much small than the usual depths anchor channels and a considerable saving of grout is achieved.

The invention is described below with reference to a preferred embodiment example with reference to the drawings. In the drawings:

1 shows a central section through a erfindungs¬ proper anchoring structure;

2 shows a cross section through the mooring construction along line II-II in Figure 1; 3 shows a section through the Verankerungs¬ construction parallel to the axis of the tie rod, in the installed state and encapsulated and Figure 4 is a representation according to FIG 2 with a secured against further rotation position of the

Anchor plate.

The tie rod has a thread at its lower end. With the SEM it is screwed in an anchor plate 2, to which a waste-circuit plate 3 is fitted with a central hole. Da¬ by the threaded portion of the tie rod can be clamped by tightening against the rear plate 3 with the anchor plate. 2 Thereby forming the drawbar 1, the armature plate 2 together with Ab¬-circuit plate 3 for the other processes by a common pERSonal. This direct screwing the tie rod into the Ankerplat¬ te 2 allows rods of any length and any Aus¬ educational use. Furthermore, so even a simple Fi¬ is xation of the anchor body for the Einbotonieren the foundation er¬ made possible. The entire anchor body 2 can matching screw are screwed from above on a transversely over the outer formwork of the th Fundamen¬ above the foundation Laid-carrier by means of a thread in the overall 14 of the anchor plate. Thus, the position of the anchor body in the foundation easily fixed, be accurately measured and controlled. In this case, this screw can be easily performed so By J, that the armature plate 2 comes to lie at the center of the body Anker¬, that the desired degree of tolerance can be utilized according to all directions. The hole in the closing plates 3 allows it an easy and safe cleaning of the thread in the anchor plate. 2

The armature plate 2 presses itself during prestressing of the tie rod against the overlying of two plates 4 ', 4 "formed Gegen¬ body. This has an opening 13, which is larger by the desired degree of tolerance than the diameter of the pull rod 1, so that before the tensioning of the tie rod 1 can be arranged offset to the foundation body to be connected to this degree of tolerance with respect to the center position.

The plates 4 ', 4 "of the counter body are welded to the form of shaped tubular hollow body from above, which has in darg presented example, a rectangular cross section. The li te Quershcnitt this form of tube is to the tolerance dimension greater than the outer contour of the anchor plate 2. are disposed the armature plate 2 is therefore placed in any direction with an arbitrary tolerance to ge desired degree of tolerance. Since the Außen¬ measure of the armature plate 2 is measured across the diagonal but larger i than the clear internal dimension of the hollow body 5, a Selbstfixier of the armature plate 2 is against given rotation, ie that the at kerplatte 2 only to a certain extent depending on the location within d tolerance against the hollow body 5 can rotate and then in each case the tie-rod 1 is not further rotate k This ensures that on the one hand the tie rod 1 from above can be screwed into the anchor plate 2 and on the other hand, the sp tere adjusting the tension rod 1 by thread and Mutte at the upper end of the drawbar 1 is possible.

The counter body 4 ', 4 "with the opening 13 has laterally at the corners of the forming tube recesses 15, so that the area de cavity below the Gegen.körpers 4', 4" and the anchor plate can be filled from above with grout.

The hollow body 5 is provided below with a bottom 6, so that no concrete can penetrate into the interior of the Ankerkör- pers during concreting of the foundation.

The respective components of the overall tensile force to be the anchor rods 7 at the corners of the hollow body 5 via the pulleys acting as a static point of walls of the forming tube. ge passes and transferring it directly into the concrete body 10 degrees. The anchor rods 7 are welded to the corners of the hollow body 5

In the carbon body 5 may advantageously be mounted threaded sleeves 8 or the like on the inside of the tube as shown in Figure 1, can be screwed into the screws. 9 By means of these adjusting screws 9, the distance between the concrete body 10 can be accurately and adjusting the body 11 to be anchored, so that this body accurately fixed in its desired position by tightening die¬ ser screws 9 or by tightening the tie rod 1 before casting of the cavities can be.

If forces are to be transverse transmitted to the drawbar 1 via the inventive direct anchoring, so can the ünterkante of the to be anchored body downwardly projecting parts mounted v / ground, for example, as Figure 3 shown a welded piece of a pipe 12, which in the cavities of the hollow body 5 protrudes above the counter body 4 * 4 ".

As a final operation, the Hohräume of the anchor body and the distance between the verbindeirienKörper to 11 and the concrete body 10 are filled with a pressure-resistant grout sixteenth So that a connection between the bodies 10 and 11 is provided by means of the anchoring structure according to the invention, which can accommodate directly at a point forces in every direction of the space.
