Definitions
- the present invention relates to a transverse force anchor as a connecting means for transmitting higher transverse forces, within components, transverse to the component direction, a connecting structure of such a transverse force anchor and the component and a method for ensuring a transmission of a force in a certain direction between any two bodies by a defined Section.
- inserts dowel-type fastening systems or anchor channels with headed bolts and other more complex shapes.
- insert results from the manufacturing process, since they are inserted attached to the formwork before concreting.
- Load-bearing means in the form of anchors for precast concrete parts are known, for example, from the prior art with reference to FIG. 1 of the document EP 0 122 521 B1.
- anchors are embedded in concrete precast concrete and loaded in the component on tensile and shear force. To remove the loads, the anchor calculations are dimensioned and integrated accordingly. Classically, these anchors are installed centrally in relation to the component thickness, since the armatures are most sensibly positioned with respect to each load. To absorb tensile loads, the anchors are provided with bolts or carry, for example, corrugated steel anchors. Due to the resulting undercuts, these anchors are anchored in the concrete and secured against tearing out under tensile load.
- the present invention has been made in view of the above-mentioned problem. It is therefore an object to provide a connecting means for transmitting higher lateral forces, which allows the use of components in a slim design.
- a transverse force anchor for transmitting transverse forces transversely to the longitudinal direction of a component within components made primarily of concrete, comprising: a connection portion for introducing at least one transverse force into the transverse force armature, with at least one load introduction portion is connected, which is contactable with the component to at least one component Kraftkom transmitted in the direction of the transverse force to be transmitted in the component, characterized in that the connection portion is spaced from the load introduction portion in the direction of the transverse force to be transmitted.
- At least one transverse force can be introduced into the transverse force anchor via the connection section.
- the transverse force can not only be transferred directly to the connection section into the component via the load introduction section, but also at least partially at the load introduction section, wherein the load introduction section is in direct contact with the component and transmits at least one component in the direction of the transverse force to be transmitted.
- the load introducing portion is spaced from the terminal portion in a direction opposite to the direction of the lateral force to be transmitted.
- the transverse force anchor has two load introduction portions for transmitting opposite transverse forces, wherein the first load introduction portion can transmit a force component in a direction of the transverse forces to be transmitted in the component, and the second load introduction portion can transmit a force component in the other direction of the transverse forces to be transmitted in the component and spaced from the first load introducing portion in the one direction of the lateral forces to be transmitted, and wherein the connecting portion is connected to both load introducing portions.
- Such a transverse force anchor is ideally suited for transmitting opposite or alternating transverse forces, wherein a load introduction section transmits, at least component by component, the lateral force in one direction and the other the transverse force at least component by component in the other direction. Since the two load introduction sections are connected to one another, the opposite transverse forces can be introduced into the transverse force anchor via a connection section and transferred from the respective load introduction section into the component. Characterized in that the second load introduction portion is spaced from the first load introduction portion in the one direction of the transverse forces to be transmitted, a large component thickness is available for the transmission of the respective force component in the direction of each transverse force to be transmitted by the respective load introduction portion.
- the transverse force anchor additionally has at least one
- Load introduction prevention section the power transmission with a component in the direction of each by the respective load introduction portion to be transmitted in each case transverse force in the component partially, but preferably completely, prevents.
- the lateral force can largely be transmitted to the component only at the defined portion of the load introduction portion.
- the load introduction prevention section thus causes the at the respective Load introduction portion transmitted force component is increased in the direction of each transverse force to be transmitted.
- a large force component is transmitted in the direction of each transverse shaft to be transmitted over a large component thickness in the component.
- the load introduction prevention section can be provided in sections at the respective load introduction section and be provided at least in sections at the connection section.
- the load introduction prevention portion may be provided spaced from the respective load introduction portion toward the lateral force to be transmitted.
- the load introduction prevention portion spaced from the respective load introduction portion toward the lateral force to be transmitted, it can be reliably ensured that a large component thickness is used for transmitting the respective lateral force into the component. Since the load introduction prevention section is provided in the direction of the lateral force in front of the respective load introduction section, a smaller portion of the component thickness than the respective load introduction section is available from the load introduction prevention section in the direction of the lateral force to be transmitted, according to the above described installation position. Since the lateral force is largely transmitted to the component via the load introduction section, a large part of the component thickness is used to transmit the lateral force.
- a further aspect of the invention provides that the force component to be transmitted from the respective load introduction section into the component can be greater in the direction of the transverse force to be transmitted than the force component to be transferred from the load introduction prevention section into the component in the direction of the transverse force to be transmitted in each case. Accordingly, the transmission of the respective transverse force into the component takes place predominantly through the respective load introduction section.
- the load introduction preventing portion may transmit a force component in the direction of the lateral force, it is always smaller than the force component in the direction of the lateral force transmitted through the load introducing portion into the component.
- a further aspect of the invention provides that the respective load introduction section can have at least one load introduction surface, which can be contacted with the component and whose technological surface normal has a component in the direction of the transverse force to be transmitted in each case.
- the load introduction surface having a technological surface normal which is the normal of the load introduction area facing away from the respective load input surface of the respective load introduction portion having a component in the direction of the lateral force to be transmitted, causes a compressive stress in the component.
- the failure form can be specifically brought about by an excavation cone, which results in pressure stress transversely to the component longitudinal direction.
- the plurality of load introduction surfaces of the respective load introduction section may be arranged in one plane.
- the load introduction surfaces of the respective load introduction section are preferably perpendicular to the direction of the transverse force to be transmitted in each case. With load application surfaces lying in one level, an easy production of the transverse force anchor can be ensured. Furthermore, a more uniform load of the component is achieved.
- the load introduction surfaces of the respective load introduction section are perpendicular to the direction of the lateral force to be transmitted, the lateral force vector and the surface normal vector of the load introduction surface are parallel, which promotes the formation of a fracture cone.
- the component is stressed transversely to the component longitudinal direction by the transferred from the load application surfaces of the respective load-introduction section component of the transverse force purely to pressure. Thus, no shear occurs at the boundary between the load introduction surface and the component.
- the load introduction prevention section can be provided at least in sections on all surfaces which lie in the direction of the respective transverse force to be transmitted from the load introduction surfaces of the respective load introduction section and whose technological surface normals have a component in the direction of the transverse force to be respectively transmitted.
- a large component of the transverse force can be specifically introduced into the component over a large component thickness, since on all surfaces which lie in the direction of the transverse force to be transmitted in front of the load introduction surfaces of the respective load introduction section and whose technological surface normals are a component in the direction of each have to be transmitted transverse force, a power transmission with a component in the direction of the lateral force to be transmitted in the component partially, but preferably completely, is suppressed.
- the formation of the fracture cone thus takes place reliably away from the load introduction surfaces of the respective load introduction section, and with the greatest possible distance from the edge of the component.
- the load introduction prevention portion is provided on all surfaces except the load input surfaces of the respective load introduction portion.
- a lateral force anchor having a large-area load introduction prevention section can further reduce the sound transmission or vibration.
- connection section can extend from the connection section to both sides, which establishes the connection to the respective load introduction section. Since the connection section is provided between the two load introduction areas, no additional installation space for the connection section in the component must be provided. The lateral force to be transmitted in each case is conducted via the webs to the respective load introduction section, the web representing a structurally simple form of the connection between connection section and load introduction sections.
- connection portion is a sleeve.
- the sleeve allows easy attachment of connecting elements for introducing forces in the transverse force anchor.
- connecting elements can be screwed into the sleeve via a thread. If the axis of the sleeve runs preferably in the component longitudinal direction perpendicular to the transverse forces to be transmitted, a bolt for load introduction into the transverse force anchor and an anchor bolt for anchoring tensile forces in the component can be mounted in the sleeve.
- the load introduction bolt can be attached to the sleeve from one direction, whereby the anchor bolt can be attached to the sleeve from the opposite direction.
- the anchor bolt prevents a tearing in component longitudinal direction with tensile load in the component longitudinal direction.
- the load introduction prevention section may be made of a compressible elastic material, preferably of closed-cell foam.
- the load introduction preventing portion can elastically deform in the direction of the lateral force, and by this elastic deformation, a springing effect occurs, whereby the lateral force is transmitted to the component only to a very small extent.
- a compressible material also permits deformations under compressive stress of the load introduction prevention section when the load introduction prevention section is surrounded on all sides by concrete and thereby transverse expansions are prevented.
- the connection portion, the webs and the respective load introduction portions may consist of a stiffer material than that of the load introduction prevention portion, preferably of galvanized steel.
- a stiffer pressure-loaded connection of the load introduction surfaces of the load introduction sections to the component results as the connection to the component by the load introduction prevention section, wherein the transverse force to be transmitted is for the most part transmitted to the component via this rigid connection and only to a very small extent via the elastically resilient load introduction prevention section.
- the principle is taken advantage of that when a force can be transmitted in one direction at several sections in a component, the majority of the force is transmitted to the connection with the greatest rigidity.
- the galvanized steel also allows good corrosion protection.
- connection structure consisting of a component and a transverse force anchor according to the invention, wherein the load introduction prevention section may be at least partially provided as a gap between the component and transverse force anchor.
- an elastic material can be partially or completely dispensed with and weight and material can be saved. If there is a gap, no component in the region of the gap is transferred to the component at all in the direction of the transverse force.
- a support structure such as a core is to be provided during the concrete pouring, which keeps the concrete at a distance. This support structure can then be removed after casting, for example by etching.
- the transverse force anchor may be provided with a dissolving material to form a gap, which dissolves after the concrete casting.
- the invention relates to a method for ensuring a transmission of a force in a certain direction between any two bodies by a defined
- a load introduction portion wherein the one body has the defined load introduction portion, through which it is in contact with the other body and the load introduction portion can transmit a force component in the direction of the force in the specific direction in the other body, and in which one body all sections except of
- Load introduction portion which can transmit a force component in the direction of the force in the specific direction in the other body, provided with a covering these sections, compared to the load introduction portion easily deformable layer and over this deformable layer in contact with the other body, wherein deforms under load of the one body by the force in the particular direction of the deformable layer and thereby transmit the force in the particular direction with a smaller component than by the load introduction portion in the other body becomes.

- the connection section 2 can also be carried out in other ways, as long as a connection element can be connected to it in a materially, positively or non-positively connected manner for introducing forces into the transverse force anchor 1.
- connection section can also be designed as a flange.
- a plastic cap 16 is shown, which is suitable as a load introduction prevention section 3 for the transverse force armature 201 shown in Fig. 6.
- Fig. 7a shows the first load introduction section 251 connected to the bridge 241 and the plastic cap 16 attached to the first load introduction section.

- the transverse force anchors according to FIGS. 8 and 9 are used as connection for e.g. Studrails. Again, however, a load introduction prevention section in the form of an elastic layer is advantageous. If this anchor is loaded with lateral force, the load introduction surfaces are subjected to pressure in the direction in which the lateral force acts. In particular, at the rear surfaces 63 of the load introduction sections 51 and 52 or 251 and 252, this pressure load is then absorbed via the elastic layers and not introduced into the underlying concrete and a punching difficult. On the uncoated surface of the load introduction surfaces, the force is introduced directly into the component. Due to the low anchoring high forces can be absorbed without punching.
- transverse force anchors according to the invention are also advantageous for lifting and erecting horizontal precast concrete elements. Due to the load introduction areas, the acting transverse forces are introduced into the component over a large part of the component thickness and the concrete can be utilized more effectively without the anchors tearing out of the concrete.
- such an anchor can also be provided with more than two load introduction sections, for example four. Such an anchor can not only remove lateral force along one axis, but along two axes. LIST OF REFERENCE NUMBERS
