Abstract
Anchoring bar (1), provided with a shaft (2) with several conical sections (7), cemented by means of a hydraulic mortar (12) in a borehole (11) made in a fixing foundation (10). When a crack appears, causing an increase in the diameter of the borehole (11), the mortar case expands, under the tractive force applied to the anchoring bar (1), as a result of a slippage of the anchoring bar (1) in relation to the hydraulic mortar (12). The outer surfaces of the conical sections (7) are therefore designed to be low in friction, provided with, for example, a coating, a film or a casing.
Description
ANCHOR ROD FOR A SYNTHETIC RESIN ADHESIVE ANCHOR The invention concerns an anchor rod for a synthetic resin adhesive anchor having a shaft which has a plurality of cone portions which are arranged in axial succession and which increase in size towards the insertion end and the surfaces of which are in the form of low-friction peripheral surfaces which do not adhere to synthetic resin mortar.
An anchor rod of that kind is known from US-A-4 305 687 and permits anchoring of a screwthreaded rod by means of a composite material in a bore hole in a concrete member after the bore hole has been conically enlarged in the region of the bottcm of the bore hole as the non-adhering low-friction cone portions permit easy sliding movement of the anchor rod with respect to the mortar material. However that known anchor rod suffers frcm the disadvantage that, when the synthetic resin mortar hardens, sharp edges are formed at the transitions between two cone portions, and those edges easily break away under load, in particular when subject to a tensile load.
Taking that state of the art as its basic starting point, the invention is based on the problem of so improving an anchor rod of the kind set forth in the opening part of this specification that high extraction values are achieved.
In accordance with the invention that problem is solved in that a cylindrical portion is associated with the cone portions in the region of the largest diameter.
The fact that each cone portion has associated therewith a cylindrical portion which is operative as a pull-over zone when the anchor rod is being extracted means that flattened tips or edges are formed in the sawtooth-profiled mortar sheath, and they do not break away even under a high level of loading.
At the same time, with such a configuration for the cone portions, the anchor rod has excellent relationships between the tensile and spreading forces, having regard to the shearing forces which occur. The flattened edge makes it more difficult for the anchor rod to be drawn through the mortar sheath as the pressure surface area for deformation of the mortar is made substantially greater and thus the relative pressure in relation to surface area as between the mortar and the wall of the bore hole is reduced.
Advantageous configurations and developments of the invention are characterised in the appendant claims.
Embodiments of the invention are described in greater detail hereinafter with reference to the drawings, in which only Figure 4 shows cylindrical portions according to the invention. In the drawings: Figure 1 is a side view of an anchor rod according to the invention, Figure 2 shows an anchor rod as illustrated in Figure 1, after 5 setting by means of a synthetic resin adhesive in a bore hole, Figure 3 is a sectional view of an anchor rod when set as shown in Figure 2, before and after the occurrence of a crack, in respective halves of the section, Figure 4 shows a further embodiment of an anchor rod according to the invention, Figure 5 is a side view of an anchor rod with cone portions of 15 different lengths and cone inclinations, Figure 6 shows an anchor rod with cone portions with different cone inclinations and the same length, Figure 7 shows an anchor rod with an end head pin, Figure 8 shows an anchor rod with an end head pin which has a resilient support means, and Figure 9 shows an anchor rod with a mixing head which is connected in position by way of a desired-rupture connection.
Referring to Figure 1, shown therein is an anchor rod 1 for a synthetic resin adhesive anchor whose shaft 2 has at its rearward end an external screwthread 3 for fixing an article. The external screwthread 3 terminates at a smooth cylindrical portion 4, the length of which permits adaptation of the depth at which the forces acting on the anchor rod 1 are applied to the fixing base.
In the embodiment illustrated in Figure 1, there are eight cone portions 7 disposed between the smooth portion 4 and the mixing tip 6 which is provided at the front end 5 of the anchor rod 1. The cone portions 7 taper in a direction fran the front end towards the smooth portion 4 and, in the embodiment shown in Figure 1, are each of the same shape with the exception of the foremost cone portion 7 which merges into the mixing tip 6. In the embodiment shown in Figure 1, the other cone portions 7 each blend into the respectively adjacent cone portion 7 by way of a respective steeply conical portion 8.
The cone portions 7 which are arranged in succession with each other are so treated on their peripheral surfaces that there is a low coefficient of friction after the anchor rod has been set into a synthetic resin. For that reason the cone portions 7 are each provided on their peripheral surfaces with a coating 9 which canprises for example a wax-like, synthetic polymer, polytetrafluoroethylene, silicone polymer or galvanically applied coats. It is also possible instead of the coating to provide a sheathing with a foil, for exanple polyethylene, polyvinyl chloride, etc. Another possible way of giving a low coefficient of friction involves providing a sheathing with a deepdrawn rigid plastics sheath or a sheathing with a deep-drawn thin metal sheath.
Figure 2 shows a fixing base 10 of concrete, in vhich a bore 10 hole 11 has been formed; after the bore hole 11 is filled with a synthetic resin mortar, the anchor rod 1 shown in Figure 1 has been inserted into the bore hole 11. As long as the fixing base 10 remains free iron cracks vhich have an effect in the region of the bore hole 11, the position of the anchor rod 1 is maintained by virtue of the positive connection between the conical portions 7 and the hardened synthetic resin mortar 12 and the connection between the synthetic resin mortar 12 and the fixing base 10, in the position shown in Figure 2.
The half-section view on the left-hand side in Figure 3 is an enlarged view corresponding to Figure 2. The right-hand half of Figure 3 shows the changes which occur when a crack occurs in the concrete 10, vhich results in enlargement of the bore hole 11. The tensile loading vhich is acting on the anchor rod 1 in Figure 3 results in axial slippage of the anchor rod 1 in the direction of the tensile force, as a result of the low coefficient of friction between the coated or sheathed cone portions 7 and the radial enlargement of the synthetic resin-free internal space vhich is created when the synthetic resin 12 hardens. In that situation, slippage occurs until the peripheral surfaces of the cone portions 7 again bear against the internal conical surfaces of the synthetic resin mortar 12, vhich are formed when the mortar hardens, and in that situation are arrested as a result of the renewed positive connection and the spreading pressure vhich is formed, in spite of the crack. The individual cone portions 7 urge the cracked plugs of synthetic resin mortar 12 radially outwardly and thus, in spite of the crack, guarantee a secure fixing action as long as the width of the crack does not ccme close to the diametral difference of the cone portions at their two ends.
As Figure 3 shows, annular cavities 13 are formed due to the slippage, the axial length thereof depending on the slippage and thus the crack width.
The above-described configuration of the anchor rod 1 thus provides that, when the anchor rod is subjected to a loading, a spreading pressure is produced which ensures that, even when the crack opens, the bond between the synthetic resin mortar 12 and the wall of the bore hole 11 is adequately maintained. After a crack has been formed in the concrete 10, the above-described bonding anchor thus functions as a spreading anchor, that is to say, the tensile force is distributed along the entire length of the anchor rod by virtue of the many cone portions 7. That provides a. pressure distribution effect which causes a uniform spreading action. Sliding surfaces are formed by the coating or sheathing between the surfaces of the synthetic resin mortar sheath and the peripheral surfaces of the cone portions 7, and very low levels of friction occur in those sliding surfaces. That not only permits the relative movement shown in Figure 3, when a crack opens, but that also provides for a relative movement which ccmpensates for the width of the crack, in the event of the crack closing.
If the crack closes, starting fran the position shown at the right in Figure 3, the radial force which is transmitted by the mortar sheath is converted by the inclinedly extending peripheral surfaces at the cone portions 7 into an axial force in a direction towards the front end 5, rearward slippage of the anchor rod being produced in that situation as a result of the sliding surfaces provided.
Although Figures 1 and 2 show eight cone portions 7, in many cases it is sufficient to provide only one single cone portion 7. For most uses the optimum is to provide fran three to four cone portions 7.
An anchor rod 1 with four cone portions 7 is shown in Figure 4. In the embodiment illustrated in Figure 4, the cone portions 7 each merge into a cylindrical portion 14, at the side which faces towards the front end 5. The cylindrical portions 14 provide for a uniform distribution of load and they prevent the cone portions fran being pulled through the mortar when a high level of loading is applied because the mortar plug which is toothed in the half-section view has wider and therefore more stable teeth, as a result of the cylindrical portions.
The embodiment of the anchor rod 1 shown in Figure 5 also has a long smooth cylindrical portion 4, like the embodiment shown in Figure 4, but the cone angle of the cone portions 15, 16, 17, 18 is adapted to increase forwardly towards the insertion end. The cone portion 15 which is adjacent the smooth cylindrical portion 4 has for example a cone angle of 11 degrees. The cone portion 16 which follows in the direction towards the insertion end has a cone angle of 14 degrees, the following cone portion 17 has a cone angle of 17 degrees and the last cone portion 18 has a cone angle of 20 degrees. The smallest diameters of the cone portions 15, 16, 17 and 18 and likewise the largest diameters are respectively equal, so that, as a result of the different cone angles towards the front end, the cone portions 15 to 18 beccme axially shorter. The fact that the cone portions 15 to 18 beccme steeper towards the front end provides for an increasing capacity for carrying tensile force, towards the front end.
In contrast to the embodiment shown in Figure 5, the embodiment shown in Figure 6 involves the same length for five cone portions 19 to of different shapes. The increasing cone inclination in a direct inn towards the front end, with the same axial cone length, provides an increasing depth of undercut configuration in a direction towards the front end in the manner shown in Figure 6; in a fashion corresponding to the cone angle which increases in a forward direction, the smaller diameter of the respective cone portions 19 to 23 decreases in a direction towards the front end. The largest cross-section in the anchor rod 1 occurs at the location at which the greatest force is applied to the anchor rod 1. With an increasing anchorage depth, the minimum cross-section of the anchor rod changes and the depth of the undercut configuration increases. That makes it possible to have a relatively greater depth of undercut configuration with a uniform diameter for the bore hole 11, while maintaining the load-carrying capacity of the anchor rod 1.
Figure 7 shows an anchor rod 1 with an end head pin 24. The front end of the anchor rod 1 is so formed by the end head pin 24 that the spreading force component is very small and the tensile force component which acts at the mortar plug is very great. The end head pin 24 has a portion 25 which converges in a heavily conical configuration, and a cylindrical portion 26.
Figure 8 shows an embodiment which is similar to that shown in Figure 7 and in which there is provided at the front end a termination cone 27 which, on the peripheral surface of its cone configuration, has a resilient intermediate layer 28 which, in spite of the steep angle, permits adequate slippage of the anchor rod 1 as is required for producing the spreading forces in the region of the shallow cone portions 7. Figure 9 shows an anchor rod having a plurality of cone portions 7, in which the mixing tip 6 shown in Figure 1 is replaced by a mixing head 29 which has a roof-shaped cutting edge 30 and which produces a mixing action when using a non-premixed mortar, while the anchor rod 1 is being inserted into the bore hole 11 by a turning movement. The mixing head 29 is connected to the foremost cone portion 7 by way of a desired-rupture location 31 which is of a such a small cross-section that the mixing head 29 tears away at just a low level of loading on the anchor rod 1, in order to permit the slippage which is required for a subsequent spreading effect when a crack occurs. Instead of the desired-rupture location it is also possible to provide a push-in connection.
