Description

[0001] The invention relates to an anchoring system for at least one building structure, in particular for anchoring at least one attachment element, such as a work platform and / or stage and / or at least one climbing system, to the building structure, wherein the anchoring system comprises: at least one anchor bolt for insertion into at least one building material; at least one anchor fixing for a detachable connection with the anchor bolt, wherein the anchor bolt can be arranged at least partially in at least one receiving opening encompassed at least partially by the anchor fixing; as well as a formwork system and a stage with such an anchoring system; and a method for providing at least one anchor point on a building structure for anchoring at least one attachment element, such as at least one work platform and / or stage, a ceiling shoe and / or a material platform, at least one climbing system and / or at least one element thereof.

[0002] Anchors are generally used to fix attachments such as climbing systems or work platforms to already cast, and possibly not yet fully cured, concrete elements of a building structure, such as walls, pillars, shafts, and / or similar structures. This allows the load to be transferred through the already constructed part of the building structure.

[0003] Add-on elements, such as stages, climbing formwork or climbing systems, or working platforms or stages, as well as material platforms and / or landing platforms, are attached to existing or under-construction structures and are supported by various mechanical systems. Climbing systems allow the formwork to "climb" along with the building structure as construction progresses. Anchoring can be achieved to vertical structures, such as walls and / or columns, or horizontal structures, such as slabs. Anchoring the add-on element to the building structure is crucial, as it ensures stability and safety during the construction process. There are essentially two main types of advancement for climbing systems: conventional climbing systems, which are often moved manually by crane lifts (crane climbing), and self-climbing systems, which are, for example, hydraulically and / or electrically driven.

[0004] Anchoring of attachment elements is achieved through anchor points integrated into the building structure. When using a building material that is at least partially pourable and / or hardenable, such as concrete, this is accomplished by encasing the anchor point and allowing the material to harden within the respective building structure, such as a concrete wall. These anchor points consist of embedded components such as anchor bolts (often also referred to as tension rods, less frequently as anchor rods) and anchor fixings, which are cast at least partially into the building material. Later, after the building material has hardened and any formwork elements used to guide and fix the material during casting and hardening have been removed, these anchor points serve as anchor points for the attachment element within the resulting building structure.These built-in components are therefore integrated into the building material, at least in some areas, so that attachments, such as formwork for a further part of the building structure to be erected, can be connected to them.

[0005] An anchor point can, for example, comprise a (formwork and / or climbing) cone forming an anchor fixing, a tension rod inserted at least partially therein, optionally screwed in, forming an anchor bolt, and an anchor plate attached to the anchor bolt.

[0006] As attachment elements, tie rods or bolts, especially for climbing formwork, can be connected to or attached to these anchor points. Brackets or climbing shoes can also be used as attachment elements. Alternatively or additionally, rails, guide rails, or brackets can be attached to the building structure.

[0007] These rails serve as guide elements for the formwork, allowing it to "climb" upwards along the structure as construction progresses. The formwork for the next construction phase or structure is attached to these rails and moved upwards by mechanical or hydraulic systems.

[0008] Consoles or work platforms for construction workers and / or materials, on the other hand, are load-bearing structural elements that are anchored directly to the building structure and support the climbing device, or are moved along with it, and simultaneously protect against the elements.

[0009] Hydraulic and / or electric lifting systems can also be used as add-on components. These enable the use of self-climbing formwork, which is hydraulically or electrically operated. A hydraulic or electric lifting system is used to move the formwork upwards without crane support, using supports at the anchor points. The hydraulic cylinders engage at least indirectly and / or indirectly, and in particular directly and / or immediately, at the anchor points in the building structure, or are supported by them, and lift the entire formwork system – including the formwork, platforms, and materials – from one construction phase, such as a concreting section, to the next.

[0010] These connections between the attachment element and the anchor point are only capable of securely holding the formwork to the building structure and absorbing the loads generated during the climbing process and concreting if the individual elements of the anchor point, such as the anchor fixing and the anchor bolt, have a predefined location and position within the building structure or material, or a specific relative position to each other. Therefore, the positions of the anchor points must be carefully calculated, as they bear significant loads. They must also have a predetermined orientation and dimensions, such as penetration depth into the building structure, ensuring correct installation within the structure. This is essential for the proper functioning and sufficient support of the anchor points. The permissible / maximum load capacities of the components and anchor points must not be exceeded.

[0011] In particular, incorrect insertion of the anchor bolt, for example, incorrect and incomplete screwing of the anchor bolt to the anchor fixing, such as the anchor cone, during formwork, poses increased risks.

[0012] Before the construction of a building section, particularly the pouring of the building material, especially concrete, the anchor components are attached to or connected to building elements such as formwork to hold them in position during the construction of the next building section, such as the pouring of the building material, like concrete. These anchor components are positioned so that, after the next building section is completed, for example, after the building material has cured, they can absorb and transfer the force exerted by the attachment elements, thus securing the attachment elements, such as the climbing formwork, to the newly constructed building section.

[0013] Typically, the structural elements used to construct the building structure, such as formwork elements, are connected to the anchor fixing using a pilot bolt to hold them in place. Once the building structure is complete, the structural element, such as the formwork, can then be removed or detached from the structure by removing the pilot bolt.

[0014] To construct the building structure, the building material, such as concrete, is poured into the space between the supporting structures, such as the formwork. This step, in particular, carries the risk of the anchor components being manipulated before and during the pouring process. For example, during such steps, especially those referred to as reinforcement work, the limited space can sometimes lead to the "manipulation" of the anchor components attached to the supporting structures, such as the formwork. These components might include anchor bolts and anchor fixings. This can result in displacement, misalignment, shifting, and / or deformation of the anchor components, for example, due to changes in the relative position of the individual components. This can occur, for instance, when reinforcement is being installed and space is limited.There is a particular risk that an anchor fixing, which has already been correctly and completely screwed in, could come loose during the formwork assembly. If the anchor components are then not correctly readjusted, safety risks arise due to "human error".

[0015] After the concrete has been poured and the position of the anchor cone or anchor fixing has been subsequently checked relative to the thread of the anchor rod or anchor bolt using a test rod or a distance meter, in the event of incorrect installation, extensive concrete reworking is necessary, which usually results in the replacement of the anchor bolt and cone.

[0016] The use of such anchors is not limited to cast building materials. They are also used in hybrid components, such as timber-concrete hybrids or structures made of other materials. In such structures, the anchor itself is inserted into the existing and / or cured structure, for example, by screwing, clipping, locking, and / or wedging it into openings or bores in the structure.

[0017] However, with known systems, continuous monitoring of the anchor parts and their components, especially the relative position of the components, is not possible. If anything, only random sampling is possible, and even then only during specific phases of the construction process.

[0018] Thus, the anchor component can only be inspected before the structural element, such as formwork, is attached to the anchor part, particularly the anchor fixing, and again after the structural element has been removed. This inspection can be carried out, for example, by manually inserting a measuring rod or caliper and / or a template into the anchor fixing, such as an anchor cone, optionally into a mounting hole for the pilot screw, to check the penetration depth of the anchor bolt into the anchor fixing. Alternatively, such an inspection can also be performed using a laser measuring device. However, this type of inspection is prone to errors and time-consuming, and is not possible after the pilot screw has been inserted because the structural element covers the anchor component or the anchor fixing, or the pilot screw closes the mounting hole.

[0019] Only after removing the pilot bolt and, if necessary, the auxiliary or structural element, such as formwork, can a further inspection be carried out. However, the discovery of misalignment or incorrect assembly due to unintentional manipulation or alteration of the anchor components during the construction phase of the structure, such as the reinforcement work, leads to enormous additional effort, particularly increased time and / or costs, which could be avoided if the error were detected earlier.

[0020] Therefore, a disadvantage of current anchoring systems is that the correct insertion of the anchor bolt into the anchor fixing, to which the attachments are anchored, must be checked manually, and continuous monitoring is not possible. Furthermore, the known systems do not allow for load monitoring and / or monitoring of the anchor point, particularly with regard to changes such as deformation of the anchor point, for example, due to overloading.

[0021] It is therefore an object of the present invention to overcome the disadvantages known from the prior art and to provide an anchor system that overcomes these disadvantages, in particular allowing misalignment and / or manipulation of the anchor parts to be detected at an early stage and to avoid or detect at an early stage an overload of the anchor system.

[0022] This problem is solved according to the invention by an anchoring system for at least one building structure, in particular for anchoring at least one attachment element, such as a work platform and / or stage and / or at least one climbing system, to the building structure, wherein the anchoring system comprises: at least one anchor bolt for insertion into at least one building material; at least one anchor fixing for a detachable connection with the anchor bolt, wherein the anchor bolt can be arranged at least partially in at least one receiving opening encompassed at least partially by the anchor fixing, wherein the anchor system further comprises at least one fastening element that can be received at least partially in at least one fastening opening of the anchor fixing, wherein the fastening element has at least one measuring device.

[0023] It is preferred that the building material is at least partially and / or temporarily pourable and / or capable of being poured, curable, cured and / or solid and / or comprises at least partially concrete, resin, at least one cementitious composite material, at least one mineral composite material, at least one non-mineral composite material, at least one cement substitute and / or carbon reduced concrete.

[0024] It is also proposed that the anchor bolt be connectable to at least one first structural element, optionally detachable, and / or that the anchor fixing be connectable to at least one second structural element, optionally detachable, wherein the first structural element and / or the second structural element comprises and / or forms at least partially at least a formwork, at least a formwork skin, at least a formwork panel, at least a stiffening element, at least a load-bearing element, at least an enclosure and / or at least a load-transfer element.

[0026] It is also preferred that the first structural element and the second structural element form a formwork, optionally for the building material, at least in some areas, and / or are spaced apart from each other by at least one gap, optionally for the partial reception of the building material and / or for the partial reception of the anchor bolt.

[0027] In preferred embodiments, it may be provided that the mounting opening is at least indirectly connected to and / or communicates with the receiving opening.

[0028] It is also proposed that the anchor fixing can be connected to the second structural element by means of the fastening element and / or that the second connecting device at least partially encompasses the fastening element and / or is formed at least partially by the fastening element.

[0029] Alternatively or additionally, it is preferred that (i) the measuring device is integrated into the fastening element and / or is arranged at least partially within an interior of the fastening element and / or (ii) the measuring device is configured to detect a relative position of the anchor bolt to the anchor fixing, at least a position and / or location of the anchor bolt within the receiving opening, a relative position of the anchor fixing to the first connecting device, a relative position of the anchor fixing to the first structural element, and / or ...

[0030] Furthermore, it is proposed for the anchor system that the measuring device be configured to detect at least one force acting on the fastening element, optionally quantitatively and / or qualitatively, preferably with regard to magnitude, direction, axial direction, transverse direction and / or moment, optionally torque and / or bending moment.

[0031] An anchoring system may also be characterized by at least one communication device, optionally arranged at least partially in the fastening element and / or at least partially encompassed by the fastening element, optionally for wired, radio-based, wireless, WiFi and / or Bluetooth communication, and / or for the output of acoustic, optical or haptic messages.

[0032] In the aforementioned embodiment, it is particularly preferred that the communication device is configured to transmit data acquired by the measuring device, in particular at least one measuring element of the measuring device.

[0033] Furthermore, it is proposed that the measuring device and / or measuring element shall include at least one ultrasonic sensor, at least one radar sensor, at least one laser sensor, at least one capacitive sensor, at least one inductive sensor, at least one optical sensor, at least one acoustic sensor, at least one strain sensor, at least one compression sensor, at least one piezoelectric sensor, at least one torque sensor, at least one contact sensor, at least one vibration sensor and / or time-of-flight sensor.

[0034] Furthermore, it is preferred that the fastening element comprises at least one evaluation unit which is optionally configured to evaluate data recorded by the measuring device and / or the measuring elements, and / or comprises at least one signaling device, wherein data evaluated by the evaluation unit can optionally be transmitted to the communication device by means of the signaling device.

[0035] Finally, it is proposed for the anchor system that the fastening element comprises a screw at least in some areas and / or forms a screw at least in some areas and / or that the fastening element is designed as a, optionally distance-measuring and / or force-measuring, lead fastening element, optionally as a lead screw, in particular for connecting the anchor bolt and / or the anchor fixing with the second structural element and / or as an, optionally force-measuring and / or distance-measuring, anchor fastening element, optionally as an anchor screw, in particular for connecting the anchor fixing with at least one attachment element, such as a support element, a climbing formwork, a tie rod, a bolt, a retaining bracket, a climbing shoe, a rail, a console, a working platform, a hydraulic and / or electric lifting system, a climbing anchor, a material platform and / or a ceiling shoe.

[0036] Furthermore, the invention provides a formwork system comprising an anchoring system according to the invention.

[0037] It is proposed that the formwork system be characterized by at least one first structural element that can be connected at least indirectly to the anchor bolt and / or a second structural element that can be connected at least indirectly to the anchor fixing and / or the first connecting device.

[0038] It is also proposed that, by means of the formwork system, optionally the first structural element and / or the second structural element, the anchor bolt and / or the anchor fixing can be at least partially surrounded by the building material.

[0039] Furthermore, the invention provides a stage comprising at least one anchor system and / or at least one formwork system according to the invention, wherein the stage comprises at least one attachment element, wherein the attachment element can be connected to the building structure and / or the anchor fixing, optionally by means of the fastening element.

[0040] It is suggested that the stage design should include: (i) the stage forms and / or includes at least a formwork system, at least a working platform and / or at least a material platform and / or (ii) the attachment element comprises at least a support element, at least a climbing formwork, at least a tie rod, at least a bolt, at least a retaining bracket, at least a climbing shoe, at least a rail, at least a console, at least a working platform, at least a hydraulic and / or electric lifting system, and / or at least a climbing anchor, at least in some areas and / or forms at least in some areas.

[0041] Finally, the invention provides a method for providing at least one anchor point on a building structure for anchoring at least one attachment element, such as at least one work platform and / or stage, a ceiling shoe and / or a material platform, at least one climbing system and / or at least one element thereof, wherein the method comprises providing an anchoring system according to the invention; the connection of the anchor bolt with at least one first structural element; Connecting the anchor bolt to the anchor fixing; and the connection of at least a second structural element to the anchor fixing by inserting a first fastening element having the measuring device into the fastening opening of the anchor fixing.

[0042] The method can further be characterized by filling at least one gap between the first structural element and the second structural element with the building material, optionally with at least partial enclosing of the anchor bolt and / or the anchor fixing by the building material.

[0043] It is preferred that the building material is hardened.

[0044] It is also proposed for the procedure that Before, during, after filling, before, during, and after hardening of the building material, the relative position of the anchor fixing to the anchor bolt is measured, monitored, controlled and / or recorded by means of the measuring device, in particular the measuring element of the measuring device.

[0045] Furthermore, the method can be characterized by releasing the connection between the second building structure and the anchor fixing by removing the first fastening element from the fixing opening of the anchor fixing and removing the second building structure element from the building structure and / or the, optionally, hardened building material.

[0046] It is preferred that The attachment element is connected to the anchor fixing by inserting at least a second fastening element into the fastening opening of the anchor fixing.

[0047] In the aforementioned embodiment, it is also proposed that the measuring device of the second fastening element be used to measure, monitor, control and / or record a force acting on the attachment element, the second fastening element and / or the anchor fixing, optionally quantitatively and / or qualitatively.

[0048] Finally, the method can be characterized in that the first fastening element is used as the second fastening element and / or the first fastening element comprises at least a distance-measuring measuring device and / or the second fastening element comprises at least a force-measuring measuring device.

[0049] The invention is thus based on the surprising finding that integrating a measuring device into a fastening element of an anchor system enables reliable and essentially unlimited monitoring of the anchor system over time. In particular, it allows for seamless monitoring of the construction process of a building structure in which the anchor system is at least partially integrated.

[0050] The anchor system according to the invention thus enables, in particular, unwanted manipulations of the anchor system to be reliably detected and rectified in real time without increased time expenditure.

[0051] In particular, the measuring device enables the determination of the relative position of the anchor fixing to its surroundings or the building structure and / or its position within the building structure. Thus, by detecting the relative position of the anchor bolt to the anchor fixing, at least one position of the anchor bolt within the receiving opening, a relative position of the anchor fixing to the first connecting device, and / or a relative position of the anchor fixing to the first structural element, such a determination of the position and / or orientation of the anchor fixing is possible. For this purpose, it is preferred that the measuring device has a distance-measuring function.

[0052] Alternatively or additionally, the measuring device can detect a force acting on the fastening element and thus indirectly on the anchor fixing, the anchor bolt, or the first connecting device, and / or a force exerted by the anchor fixing, the anchor bolt, or the first connecting device on the fastening element. In this way, for example, unintentionally exerted torques, torsional stresses, tensile stresses, buckling stresses, and / or compression stresses on the anchor system can be detected.

[0053] In cases where the fastening element is used as a pre-fixing element, particularly a pre-fixing screw, the critical phase of structural construction, during which, for example, the building material such as concrete is poured into the space between the supporting elements, such as the formwork, can be monitored. This minimizes the risk of unnoticed manipulation of the anchor components before and during the pouring process, especially during the reinforcement work. Such manipulation could, for example, consist of a displacement of the anchor system elements, such as a shift of the anchor bolt relative to the anchor fixing. This displacement can then be detected by the change in position itself, as measured by distance measurements, and / or by the forces acting upon it, such as a torque on the anchor bolt, which is then transmitted to the anchor fixing.For example, if the anchor bolt is screwed into the anchor fixing, torque can cause the anchor bolt to be screwed further into or out of the fixing, leading to undesirable changes in position or relative orientation. Therefore, using the fastening element as a preliminary fastening element allows for early inspection and fault identification as soon as an auxiliary component, such as a formwork panel, is attached to the anchor system.

[0054] However, the anchoring system is not limited to monitoring the anchoring system during the installation process within the building structure. When the fastening element is used as an anchor fastening element for the attachment element, the loads on the anchoring system after connection with the attachment element can also be monitored. On the one hand, the loads can be monitored directly using a force-measuring device to detect impending or existing overloads of the anchoring system and / or the building structure in which the anchoring system is installed. However, the supplementary or alternative use of a distance-measuring device also readily enables the detection of such existing or impending overloads. Thus, the position and / or...Position determinations allow conclusions to be drawn about material deformations and / or the forces acting on the anchor system, and an overload should be detected if these forces exceed a limit value.

[0055] Leading fastening element, in particular leading screw, and anchor fastening element, in particular anchor screw, can differ in their geometry, such as length, width and / or thread parameters.

[0056] The measuring device can comprise one or more measuring elements based on various sensing methods. Combinations of such methods are particularly advantageous. For example, combining force-sensing sensors, such as torque sensors, strain sensors, compression sensors, and / or piezoelectric sensors, with distance sensors enables improved determination of the relative position of the anchor system elements, such as the screw-in depth of the anchor bolt in the anchor fixing. The torque provides information about the force acting on the anchor bolt or the anchor fixing due to the resistance encountered during screwing in or out. The torque curve reveals whether relative movement occurs, for example, after overcoming static friction and transitioning to sliding friction.The results of the torque curve analysis can then be redundantly verified by using the distance sensor to determine the actual distance or overlap of the elements, such as the penetration or screw-in depth of the anchor bolt into the anchor fixing. Alternatively or additionally, a vibration sensor can be used to detect vibrations that occur during insertion or screwing in and / or withdrawal or unscrewing, particularly of the anchor bolt from the anchor fixing, and thus allow conclusions to be drawn about the relative change in position.

[0057] Furthermore, optical sensors, radar sensors, and / or laser sensors enable non-contact measurement of the relative position of the elements, such as the penetration or screw-in depth of the anchor bolt into the anchor fixing. Based on the properties of reflected light, these sensors measure the distance between the fastening element and, consequently, due to the predefined position of the fastening element relative to the anchor fixing, the distance between the anchor fixing and the surface of the other element, such as the anchor bolt.

[0058] Similarly, the use of an acoustic sensor and / or ultrasonic sensor enables non-contact distance measurement by evaluating the reflections of sound waves. This method can be particularly useful in situations where other sensors, such as optical sensors, have difficulty performing accurate measurements, for example, because there is no direct optical connection to the other element.

[0059] Similarly positive effects can be achieved through the use of inductive and / or capacitive sensors. These can detect the position of the elements of the anchor system relative to the fastening element by sensing changes in the electromagnetic field or capacitance. These sensors are capable of determining and / or tracking the position and / or movement of an element of the anchor system relative to the fastening element or the anchor fixing positioned relative to the fastening element, without requiring direct optical or mechanical contact.

[0060] The use of a contact sensor makes it possible to detect a change in position when one of the elements, in the predetermined, desired relative position to the anchor fixing in which the fastener is located, comes into contact with the fastener. Movement of the element, such as the anchor bolt, relative to the fastener and thus relative to the anchor fixing, can then be detected by the breaking of the contact.

[0061] The use of an evaluation unit offers the advantage that the measured values ​​provided by the measuring devices or measuring elements can be evaluated and assessed directly within the anchor system. This allows for the output of various messages to the surrounding environment.

[0062] A communication device can include an output unit for acoustic and / or visual signals. Such an output unit could, for example, trigger an acoustic warning, such as a warning tone, if the measuring device detects values ​​that are outside the acceptable range. This warning signal could alternatively or additionally be displayed visually, for example, as a red light signal. Optionally, the output unit could also display a green light signal when measured values ​​are within an acceptable range. Alternatively or additionally, the output unit could also provide haptic signals, such as vibrations, whereby the anchor system itself and / or at least one of its elements could be used as a resonator to generate an acoustic signal.All these messages enable a user within range of the anchoring system to detect an overload or misconfiguration. In particular, the correct function and configuration of the anchoring system can be checked at any time via a simple visual inspection. Furthermore, a simple setup is achieved, as the anchoring system, especially the fastening element, only requires an output unit that reacts to signals supplied by the evaluation unit, such as digital signals, in order to issue a message, optionally of a qualitative nature.

[0063] Alternatively or additionally, the communication device can also enable wired and / or wireless communication with other devices or systems. This allows measured values, data, and / or signals from the measuring device, the measuring element, and / or the evaluation unit to be transmitted to an external unit, such as a central monitoring unit. In this way, multiple anchor systems can be networked.

[0064] Networking offers several advantages, including redundant monitoring by enabling the simultaneous central monitoring of multiple anchor systems. Data, signals, and / or measurements can also be transmitted to a gateway, particularly via short-range communication such as Bluetooth and / or Wi-Fi. This allows for the automatic detection and assignment of sensor nodes, as well as the wireless transmission of data to a remote monitoring system.

[0065] Remote monitoring can further analyze the data provided by the anchoring systems and issue corresponding messages and instructions for resolving overloads, such as load limits for specific areas of the building structure and / or the climbing system. Furthermore, this data can be evaluated in conjunction with other data, for example, from the climbing formwork, the climbing system, or the brackets or platform. This allows for more targeted and earlier warnings of impending overloads or data comparisons with the climbing hydraulics. For example, the climbing hydraulics are blocked if safe climbing is not possible under unsafe conditions.

[0066] Furthermore, due to the essentially complete overview of the acting forces, approvals can also be given for certain areas to increase the load, such as the additional use of attachments like platforms or brackets for storing material, such as formwork elements.

[0067] The integration and / or arrangement of the measuring device, at least in part, into the fastening element offers the advantage that it is protected from external environmental influences and at the same time the inherent stability and function of the fastening element are not negatively affected.

[0068] Overall, using the fastening element as a preliminary fastening element allows for a quick overview of whether all anchor systems are ready for pouring the building material, such as concreting, and in particular whether they are positioned and / or configured within tolerances. This enables troubleshooting after formwork and before pouring, thus avoiding time-consuming and costly rework that can lead to construction delays.

[0069] Furthermore, the recording of relevant measurements by the measuring device allows for complete documentation of the construction process of the building structure with regard to the safety-relevant anchoring systems. This enables, for example, proof of the compliant use and application of the anchoring systems, even in the event of a malfunction or incident. Moreover, the documentation allows for real-time monitoring from installation to dismantling or removal of the anchoring system.

[0070] Overall, this results in a minimization of risks by enabling continuous monitoring of the anchor points from the installation of the anchor fixings and anchor bolts through use to removal.

[0071] Further features and advantages of the invention will become apparent from the following description, in which preferred embodiments of the invention are explained with reference to figures.

[0072] This shows: Fig. 1 a top view of a building structure in which an anchoring system according to the invention is used; Fig. 2. A top view of a section of the building structure of the Fig. 1; Fig. 3 A perspective side view of a climbing system after attachment to the building structure of the Fig. 1 and Fig. 2 by means of an anchor system according to the invention; Fig. 4 a perspective side view of an anchor system according to the invention; Fig. 5. Supervision of the anchoring system of the Fig. 4 from direction A into Fig. 4; Fig. 6a to 6c Views of a fastening element of the anchor system of the Fig. 4 and Fig. 5; and Fig. 7a and Fig. 7b Views of another fastening element of the anchor system of the Fig. 4 and Fig. 5.

[0073] Fig. Figure 1 shows a top view of a building structure 1. The building structure 1 is a wall that at least partially comprises a cast and hardened building material in the form of concrete. Attachment elements in the form of hydraulic climbing systems 5 and platforms in the form of work platforms 7 are anchored or fastened to the building structure 1 by means of anchor points comprising anchor systems 3a according to the invention.

[0074] The anchor systems 3a comprise fastening elements in the form of fastening screws 9a, which are designed as anchor screws. The fastening screws 9a are screwed into anchor fixings of the anchor systems 3a. As explained below, measuring devices 13a are integrated into each fastening screw, enabling the measurement of forces acting on the fastening screw 9a, in particular axial and / or shear forces.

[0075] Furthermore, the structure is supported by five structural elements in the form of formwork 11a and 11b, which are attached to the climbing system. The formwork 11a and 11b creates a space into which concrete will be poured in a subsequent construction step to extend the structure. Anchor systems 3b are located in the area of ​​the formwork 11a and 11b. As explained below, these anchor systems 3b extend through the space and thus define the size of the space and therefore the thickness of the concrete wall section to be poured to extend the structure 1. Furthermore, the anchor systems 3b are integrated into the structure 1 during the pouring of the concrete, so that after the concrete has hardened and the formwork 11a and 11b have been removed, they will serve as anchor points for the concrete then poured into the structure 1. Fig. 1. Climbing system extended upwards to act.

[0076] In the Fig. In the construction phase of the building structure 1 shown in Figure 1, the anchor systems 3b are connected to the formwork 11b, at least on the side facing the climbing system 5, by means of fastening elements in the form of fastening screws 9b. The fastening screws 9b are designed as pilot screws, in particular for distance measurement. As explained below, they thus allow monitoring of the position of individual elements of the anchor systems 3b relative to the formwork 11a, 11b, or monitoring of the relative position of individual elements of the respective anchor system 3b to each other. For this purpose, measuring devices 13b are integrated into the fastening screws 9b, which enable distance measurement.

[0077] The mounting screws 9a, 9b also feature communication devices that enable radio-based transmission of measurement data from the measuring devices 13a, 13b or of messages and / or signals generated from the measurement data of the measuring devices 13a, 13b by means of an evaluation unit integrated in the mounting screws 9a, 9b. In particular, the transmission can take place via a short-range radio technology standard, such as Bluetooth. Transmission can be made to at least one gateway 17, whereby the data is then forwarded via a further radio link 19, such as a mobile communication link, to a central monitoring unit 21. Optionally, the monitoring unit 21 is connected to the climbing system 5 for the evaluation of measurement data from the climbing system and / or for the control of the climbing system 5.Furthermore, the monitoring unit 21 enables the transmission of messages and instructions to a mobile device 23 via a communication path 25, such as the World Wide Web.

[0078] In Fig. Figure 2 shows a section of the building structure 1, omitting the work platforms 7 and the climbing system 5. This allows a view of two anchor systems 3a, shown without the corresponding fastening screws. The anchor systems 3a comprise anchor fixings in the form of anchor cones 27. Threads 29, into which the fastening screws 9a and 9b can be screwed, are integrated into these.

[0079] In Fig. Figure 3 shows a side view of the anchoring of the climbing system 5, here in the form of a hydraulic self-climbing system, to the anchor systems 3a by means of in Fig. 3, the fastening screws 9a covered by the climbing system 5 are shown.

[0080] In Fig. Figure 4 shows an anchor system 3b according to the invention before connection with the formwork 11a, 11b and the pouring of the concrete between the formwork 11a, 11b. The anchor system 3b comprises an anchor bolt 31, which projects partially into the anchor cone 27. For this purpose, the anchor bolt 31 is inserted into a receiving opening 33, in particular screwed in. A first connection device in the form of a fixing foot 35 is arranged at the end of the anchor bolt opposite the anchor cone 27. Such a fixing foot is also referred to as an anchor plate. Alternatively, the anchor bolt 31 can also be anchored through the building structure, in particular a ceiling, and screwed to a recoverable threaded plate. Walls are also sometimes anchored through the wall. However, a typical application is as a "permanent anchor" in the form of a tension rod with a threaded plate.

[0081] The anchor system 3b, in particular the anchor bolt 31, can be connected to the formwork 11a by means of the fastening foot 35.

[0082] In Fig. Figure 5 is a top view of the anchor system 3b, in particular the anchor cone 27, from direction A in Fig. 4 shown. We Fig. As can be seen from Figure 4, the anchor cone 27 has a mounting opening 37 for receiving the mounting screw 9b or, alternatively, the mounting screw 9a. The mounting opening 37 opens into the receiving opening 33 on its rear side. The mounting opening 37 and the receiving opening 33 are thus connected and communicate with each other. Therefore, the end of the anchor bolt 31 is visible through the mounting opening 37. This makes it possible to determine the position of the anchor bolt 31 within the anchor cone 27 by measuring the distance within the mounting opening 37.

[0083] To enable such a distance measurement, the fastening screw 9b, as shown in Fig. As shown in 6a, a corresponding measuring device 13b is located on the side to be inserted into the mounting opening 37. The measuring device 13b comprises measuring elements 39 that enable distance measurement. If the mounting screw 9b is tightened as shown in 6a, a measuring device 13b is provided on the side to be inserted into the mounting opening 37. Fig. As shown in Figure 6b, the fastening screw 9b is inserted into the fastening opening 37, in particular by means of the thread formed in the anchor cone, and is thus fixed relative to the anchor cone. Specifically, the fastening screw 9b, acting as a pilot screw, connects the anchor cone to the formwork 11b. The distance to the anchor bolt 31 located in the receiving opening 33 of the anchor cone 27 can be determined by the measuring device 13b or its measuring elements 39. This determination is possible at any time, even if there is no visual contact with the anchor bolt 31 from the outside, such as after the connection of the anchor system 3b to the formwork 11a, 11b and / or during or after the pouring of the concrete.

[0084] In Fig. Figure 6c shows a top view of the end of the fastening screw 9b facing away from the measuring device 13b or the measuring elements 39, or the end of the fastening screw 9b facing away from the thread of the fastening screw 9b. As the Fig. As can be seen in Figure 6c, a further communication device 41 is arranged at this end of the fastening screw 9b. This communication device allows optical signals to be output. A light source, such as an LED, can output a first optical signal to the communication device 41 if the measured values ​​acquired by the measuring element 39 remain within a predefined limit, and a second signal, in particular a warning signal, if the acquired measured values ​​exceed the predefined limit. In this way, it can be indicated at any time if the relative position of the anchor bolt 31 to the anchor cone 27 is outside a tolerance range.

[0085] In the Fig. 7a and Fig. Figure 7b shows top views of the fastening screw 9a, which can be used as an anchor fastening screw. Fig. 7a shows the head of the fastening screw 9a, while in Fig. Figure 7b shows the end of the fastening screw 9a that can be inserted into the fastening opening 37 of the anchor cone 27. Fig. 7b the measuring elements 43 designed as force-measuring elements in the fastening screw 9a are recognizable.
