Definitions

  • the invention relates to a connection system for connecting a first component to a second component, as it is used regularly for the connection of concrete slabs, according to claim 1.
  • a Schubdornharm of the type mentioned for the connection of two concrete slabs is from the EP 0 886 008 A1 known.
  • Such Schubdorntagenen usually serve to produce expansion joints in reinforced concrete.
  • Schubdorntagenen be required when relative movements of the concrete components to be joined must be made possible due to stress or thermal expansion, so that the concrete components are not damaged.
  • the Schubdorntagenen serve in such systems for receiving and transmitting shear forces.
  • the in the EP 0 886 008 A1 described Schubdornharm comprises an anchoring plate on which a load distribution tube is held.
  • This anchoring plate surrounds the load distribution tube in the manner of a flange.
  • a sliding sleeve which is held in the load distribution tube, on the front side of the component, by a solid shoulder.
  • anchoring brackets are welded to the anchoring plate.
  • the initially free space between sliding sleeve and load distribution pipe is poured with concrete.
  • the shoulder is designed such that the forces are efficiently directed radially outwards can be.
  • the load distribution in the axial direction is effected by the seated on the shoulder tube, which is filled by the on-site concrete.
  • Type N thrust mandrel connections permit movement of the reinforced concrete components relative to each other in the direction of a mandrel axis of the mandrel.
  • Type Q connections allow for both mandrel and transverse movement.
  • Type Q connections thus have two degrees of freedom, type N connections only one degree of freedom.
  • From the EP 0 773 324 A1 is a device for connecting and for absorbing transverse forces of two separated by a joint components, in which the particular concrete components are connected by means of a mandrel.
  • One of the two end portions of the mandrel is embedded in the first component, while in the second component, a sleeve is inserted, in which the other of the two end portions of the mandrel penetrates.
  • On the mandrel and the sleeve flange-like discs are arranged in each case in the region of the joint, which are aligned substantially perpendicular to the mandrel and sleeve and which are at least partially embedded in the corresponding components.
  • the flange-like discs may be formed as part of plates, which are bent into a box profile and which have recesses for receiving anchoring brackets, by means of which the plates are cast in the concrete component.
  • the mandrel is guided in the box profile both on the side facing the joint, and on the side facing away from the joint of the box profile.
  • a disadvantage of this solution is that long spikes must be provided by the relatively large expansion of the boxes in the mandrel direction. These are usually made of stainless steel because they are exposed to moisture and would otherwise tend to rust. However, such long mandrels made of stainless steel are relatively expensive. Another disadvantage is that the box-like plates tend temperature and age to deformation, so that the sleeve side no proper guidance of the thrust mandrel can be guaranteed more. As a result, friction noises can occur, which continue in a building as structure-borne noise and thus lead to significant impairments or even significant structural defects.
  • EP 0 943 744 A1 describes a system of two shear force element for the introduction of shear forces in a concrete body, which are poured, for example, in two concrete parts to be joined together.
  • the one element has a shear force mandrel and the other element a shear force sleeve, wherein the shear force mandrel bridged the gap between the two concrete slabs in the shear force sleeve inserted.
  • Scherkraftdorn and Scherkraftthülse a narrow loop element is ever arranged, with leg portions of the loop elements are arranged directly on both sides of the joint, ie on the front side of the concrete slab.
  • the symmetrically formed loop elements are bent from an example.
  • EP 0 032 105 A1 describes a connecting element for two concrete parts, which provides a cast-in in the first concrete part sleeve and a cast into the second concrete part mandrel, which penetrates the sleeve.
  • Sleeve and mandrel are provided with reinforcements that reduce or reduce concrete-specific load peaks
  • a fastener for concrete components is known in which a profile mandrel is provided for connecting two concrete components, which has partitions padding, which allow a certain elasticity of the concrete components relative to the fastener to reduce stress peaks in the concrete components.
  • the DE 199 64 031 A1 describes a sleeve / mandrel connection for transmitting transverse forces between two adjacent components.
  • the sleeve of this compound is provided on its front side with a front plate.
  • the sleeve is surrounded by multiple U-shaped bent pressure distribution elements, which are also attached to the back of the face plate.
  • a corresponding structure is provided for the mandrel associated with the other component.
  • the DE 1 659 187 A describes a horizontally displaceable sliding anchor for transmitting vertical loads from one component to another component. It is used a rod or thorn-shaped anchor.
  • This armature is arranged so that one end thereof is fixedly connected to the one component and is horizontally displaceable with the other component and rotatably connected about at least one axis.
  • this armature is held movably in the other component in a sleeve firmly integrated therein.
  • the sleeve contains elements that improve the slidability of the anchor therein.
  • a disadvantage of the fastening element known there that it has no sufficient edge strength, so that the concrete in the region of the joint can break despite the padding.
  • the concrete components can move through the required thick padding against each other in the direction of force, so that the dimensional accuracy of the components to each other is not particularly large.
  • connection system of the type mentioned in that it allows a high-strength connection of the components without the risk of damage to two components, the connection system allows proper management of the mandrel and wherein the connection system is also more cost effective to produce as known from the prior art systems.
  • connection system according to claim 1.
  • An inventive connection system for connecting a first component to a second component has a sleeve part which can be fixed by means of a reinforcement in the first component.
  • the reinforcement serves to strengthen the component and gives it a higher load capacity.
  • a mandrel part is provided which can be fixed in the second component by means of a reinforcement. The mandrel is feasible in the connected system of the two components in a sliding sleeve of the sleeve part.
  • the holding element in the form of the rectangular profile or the trapezoidal profile has two parallel opposing surfaces. This profile is aligned parallel to the joint-side end face of the corresponding component. Such a profile is preferably used for both the sleeve part and for the mandrel part.
  • the sliding sleeve of such a sleeve part then runs preferably at right angles to these parallel surfaces of the holding element.
  • other profiles are possible, but two opposite, essentially should have parallel surfaces through which the sliding sleeve of the sleeve part or the mandrel of the mandrel part leads.
  • Such a holding element has the further advantage that it can be arranged very close to the joint with the one surface part of the two parallel surfaces. Due to the course of the holding element parallel to the component joint, the holding element can be made very long, since it does not penetrate into the reinforcement of the component by its position on the edge of the component. Consequently, it is possible to involve a much larger area of the reinforced concrete component at the local load entry, since a larger so-called puncture cone is formed.
  • the transverse force is transmitted through the joint through the mandrel.
  • the holding element preferably concreted stainless steel tube
  • the mandrel is guided exactly, and due to the geometry of the holding element (rectangular profile or trapezoidal profile) a clamping of the mandrel is achieved by the opposite parallel surfaces.
  • the mandrel is thereby only veryrtz.vercardt directly at the gate of the component edge.
  • This design of the retaining element also makes it possible to use a very short mandrel, which then does not hit the component-side reinforcement.
  • the transferred transverse force can be introduced into the reinforced concrete component by welded reinforcement stirrups.
  • the reinforcement may be part of an already existing component-side reinforcement or may be a reinforcement belonging to the connection system, which is integrated with the system together in the components.
  • the first and the second component consist of regular concrete, reinforced concrete or other materials that are cast for the production of components.
  • the two components form a joint to each other, which serves to compensate for relative movements of the two components, for example, caused by temperature changes.
  • Preferred applications of the connection system thus exist in particular for components with large dimensions, which are too large Extensions to temperature changes tend, for example, bridges or larger concrete slabs in buildings.
  • the gap between the components can for example be filled with an elastic material, which among other things can also have thermal insulation properties.
  • a holding element for holding the sliding sleeve which consists of at least two different materials. With the help of at least two different materials, the requirements for a holding element for holding the sliding sleeve can be realized much better.
  • the holding element on the one hand partly of a particularly tensile material and on the other hand partly made of a particularly pressure-resistant material, whereby the forces transmitted through the connection system forces can be absorbed particularly well on mandrel, sleeve and retaining element and forwarded into the component.
  • this can also be constructed particularly compact compared to holding elements known from the prior art, which facilitates the assembly of the holding element in the production of the first component.
  • this can also be constructed particularly compact compared to holding elements known from the prior art, which facilitates the assembly of the holding element in the production of the first component.
  • the holding element further requires that only the joint itself must be taken into account for the static calculation of the components and the connection system, since the mandrel is so cleanly guided by the optimized holding element, that the majority of the forces on a side facing the joint of the components from the mandrel is introduced into the holding element and from there via the reinforcements in the components itself.
  • the mandrel which usually consists of expensive stainless steel, can thus be designed to be particularly short; it merely has to pass completely through the retaining element even at the maximum joint.
  • the holding element is designed as a hollow profile, the cavity is filled with high-strength concrete.
  • the high-strength concrete has a particularly high compressive strength.
  • the holding element then ensures that the sliding sleeve and in the sliding sleeve of the mandrel are cleanly guided, since the compact, high-strength and thus distortion-free holding element tends to much less deformation than the known in the art large-sized holding elements. This results in much lower friction stresses in the mandrel, allowing for better guidance and minimizing the occurrence of friction noise.
  • the holding element is preferably made of stainless steel or stainless steel, since such a holding element can withstand better penetrating, offset with electrolyte moisture.
  • the holding element is designed as a rectangular profile. Rectangular profiles are compared to other profiles, extremely compact, so that the holding element requires compared to other designs smaller space.
  • the holding element can be arranged by the flat sides of the rectangular profile particularly far forward of the component boundary or joint in the first component, which reduces the load on the first component by improved power dissipation in the relevant area. It is therefore essential that the holding element is formed from a profile having two parallel surfaces.
  • the Parallel surfaces are aligned parallel to the joint-side end face.
  • Trapezoidal profiles allow minimizing the size of the holding part, since the trapezoid can be dimensioned according to the static loads.
  • connection system provides that in the holding element a plurality of juxtaposed brackets are arranged for a plurality of mandrels.
  • a holding element of greater length can be specified, in which a plurality of mandrels can be arranged and guided next to one another.
  • large loads can be transmitted over several parallel mandrels without having to choose a larger mandrel diameter of a single mandrel.
  • a flexible element is arranged on the holding element, which ensures a flexibility of the holding element in the edge region.
  • the flexible element preferably consists of one or more strips which are arranged in areas of possible force peaks.
  • a further sleeve is arranged, which has a horizontal opening, the same size or larger is considered the largest transverse dimension of the sliding sleeve.
  • the opening of the further sleeve is preferably oval, slot-like or rectangular.
  • the larger opening of the further sleeve allows the sliding sleeve can be received in the other sleeve, and that the sliding sleeve in the other sleeve can slide or roll.
  • Oval, slot-like or rectangular openings of the further sleeve allow particularly compact designs of the further sleeve.
  • the holding element and the reinforcement in the axial direction of the mandrel are connected in series.
  • the holding element and reinforcement are particularly easy to connect to each other, when providing substantially the same materials, for example by welding.
  • the reinforcement can also consist of structural steel, which can be welded to steel or stainless steel.
  • the holding element particularly far forward in the region of the joint between the first component and the second component, preferably directly on the edge of the component.
  • the reinforcement corresponds to the usual edge surrounds, so that the installation of the system is particularly easy, and that the installation of the other component-side reinforcements in areas where no Schubdorntagen is provided, not hindered is.
  • a further particular advantage results if in the mandrel part, a further holding element is provided for the mandrel, which is the holding element of the sliding sleeve substantially in the different embodiments described above equivalent.
  • a particularly good force introduction of the forces occurring in the second component can also be accomplished on the arbor side, so that edge chipping in the second component can likewise be prevented here and the thrust mandrel can be mounted particularly easily.
  • a guide sleeve for the mandrel is provided in the mandrel part, within which the mandrel is fixable.
