Description

[0001] The invention relates to a support device, a support arrangement, a console and a method.

[0002] Structural loads, such as ceiling loads, can be supported on structural supports, among other things. Supporting devices are used in addition to structural supports to support loads, either permanently or temporarily. Permanent use is considered when it is determined that the load-bearing capacity of the structural supports themselves is insufficient and / or the load-bearing capacity of the supported ceilings is insufficient. Temporary use is considered when the structural supports require repair. Structural supports can be constructed as concrete pillars or reinforced concrete columns, which, particularly in underground car parks, are exposed to damage from road salt containing sodium and / or calcium chloride.If the chloride content in the concrete in the immediate vicinity of the reinforcement exceeds the critical chloride content, pitting corrosion of the reinforcement occurs, leading to significant local cross-sectional losses and a loss of structural safety. To repair the structural columns, the chloride-contaminated concrete is partially or completely removed, particularly in the area of ​​the column base. The removal of the chloride-contaminated concrete is carried out using high-pressure water jetting or, in special cases, by chiseling. During reprofiling, the column bases are protected from further chloride contamination using grout or shotcrete. Additional support for the slab is required during the repair.

[0003] It is known from the prior art to provide tree trunks, floor supports for floor formwork, or similar devices at a distance from structural supports that are to be repaired or additionally supported. Due to the resulting shift in the flow of forces, the floors must also be supported in a "shifted" manner on the floors above, particularly in multi-story buildings where the load-bearing structural supports are often arranged one above the other across multiple floors. This is associated with considerable effort in tall buildings and is not possible in residential or office spaces without interfering with normal use.

[0004] The invention is therefore based on the object of providing a support device which eliminates the disadvantages of the prior art, in particular provides a compact support close to the column and / or makes additional support in further floors unnecessary.

[0005] The object underlying the invention is achieved by a support device with the features of claim 1. The invention is directed to a support device for load introduction and / or load discharge on a structural support extending along a support axis, the support device comprising: a support receptacle for receiving the structural support, at least one bracket for arrangement on a shell side of the structural support extending substantially parallel to the support axis in a support state, at least one, in particular at least two, first clamping devices extending parallel to an x-axis and / or perpendicular to the shell side for applying a first force component perpendicular to the support axis, in particular perpendicular to the shell side, to the shell side of the at least one bracket in the support state,wherein the at least one first clamping device extends through the at least one bracket and / or is arranged at least partially in the bracket, in particular between an inner wall and an outer wall of the bracket, at least one force conduction device for applying a second force component parallel to the support axis to the at least one bracket in the supported state.

[0006] The support receptacle is delimited by the at least one bracket, in particular its inner wall, and the at least one first clamping device. The at least one clamping device protrudes parallel to the x-axis, preferably on both sides, relative to the support receptacle, in particular relative to the bracket.

[0007] If at least two clamping devices are provided, the support receptacle is preferably arranged parallel to a y-axis which is perpendicular to the x-axis, between the at least two clamping devices.

[0008] Consequently, to support the building or the floors above it, the force is transferred from the ceiling through a portion of the building support into the support device, and then transferred through the support device into the ground. Due to the positioning of the support device directly on the building support, the device is compact. Furthermore, this prevents a shift in the force flow, meaning that additional floors above the supported floor do not need to be supported. This reduces the effort required for supporting the structure, both for permanent and temporary use. In this case, the second force component preferably runs vertically upwards, particularly against the force of gravity.

[0009] Furthermore, the support device can provide a support element or support element arranged on the structural support, on which a load-dissipating element can be placed or supported. This can be used, for example, to support a ceiling that is not sufficiently load-bearing by means of a girder and the support device, or to retrofit an intermediate ceiling or a guideway for an overhead crane to an existing structural support. The load is transferred from the load-dissipating element, in particular the girder, the intermediate ceiling or the guideway, into the support device and introduced from the support device into the structural support. In this case, the second force component preferably runs vertically downwards, in particular along the force of gravity.

[0010] For the purposes of the invention, a "supporting state" is understood to mean that the support device is arranged on the structural support and the force flow of the load of the structure, in particular the ceiling, the beam, the suspended ceiling, or the guideway, passes at least partially through the support device. For the purposes of the invention, structures can include, among other things, buildings, in particular multi-story buildings with structural supports, preferably with an underground car park, and bridges, in particular with bridge piers.

[0011] The power transmission device is preferably designed as a second tensioning device, in particular as a hydraulic and / or pneumatic and / or mechanical press. The second tensioning device can be arranged on a profile block, in particular a profile block made of steel. The power transmission device can additionally or alternatively be designed as a load-bearing element, in particular as a beam and / or a suspended ceiling and / or a guideway of an overhead crane.

[0012] It is advantageous if, in the supported state, an intermediate space is formed which is delimited by the bracket and the structural support. It is additionally or alternatively advantageous if an intermediate layer is provided which is arranged between the at least one bracket and the shell side and which connects the bracket and the shell side in a force-fitting and / or form-fitting and / or material-fitting manner. It is further advantageous if, in the supported state, the intermediate layer is arranged in the intermediate space. The intermediate layer can be designed as a casting compound. The casting compound is preferably flowable and / or curable. The intermediate layer can additionally or alternatively be designed as an adhesive layer and / or plastic layer, in particular a hard rubber layer.

[0013] An advantageous aspect of the description provides that the bracket has a base body, the base body comprising: an inner wall facing the shell side, an outer wall facing away from the support axis and opposite the inner wall, and a bracket ceiling connecting the inner wall and the outer wall, and / or a bracket base connecting the inner wall and the outer wall, and / or at least one intermediate wall arranged between the inner wall and the outer wall. The bracket is preferably designed as a welded construction, in particular as a welded steel construction. The bracket is preferably made of high-strength steel. The bracket is preferably designed like a frame. The first clamping device preferably extends between the inner wall and the outer wall, in particular protrudes perpendicular to the support axis relative to the inner wall and the outer wall.The bracket is therefore designed as a rigid structure that can optimally transfer forces from the structural support and / or the ceiling and / or the floor and / or into the structural support and / or the ceiling and / or the floor. For the purposes of the invention, "ceiling" refers to the floor and "floor" refers to the floor.

[0014] The bracket, in particular the base body, preferably has one, in particular two, spacer elements which protrude from the inner wall and / or are arranged between the inner wall and the shell side in the supported state. This ensures that an intermediate space is provided between the bracket and the shell side into which a casting compound can be poured. Alternatively, the bracket can be formed on the inner wall corresponding to the shell side, in particular not have any spacer elements. An intermediate space for receiving an intermediate layer, in particular a casting compound, can be provided by arranging the bracket at a distance from the shell side before the intermediate layer, in particular the casting compound, is introduced and / or cured.

[0015] The inner wall of the base body is preferably integrally formed with the shell side of the structural support. The inner wall can preferably be flat if the shell side is flat. The inner wall can preferably be curved, in particular circular, if the shell side is curved, in particular circular. Alternatively, the inner wall can be wave-shaped.

[0016] An advantageous aspect of the description provides that the shell side facing the console in the supported state and / or the console, in particular the inner wall, preferably an inner side of the inner wall facing the shell side, is textured and / or profiled and / or structured. The surfaces are uneven, i.e. they do not run in one plane. Texturing is understood to mean an uneven and / or random distribution of elevations and depressions, such as an increased roughness of the surface. Profiling is understood to mean a regular and / or repeating distribution of elevations and depressions, such as a wave or tooth pattern. It is advantageous if the shell side and / or the console, in particular the inner side of the inner wall of the console, has at least one elevation section and at least one depression section alternating parallel to the support axis.It is further preferred if the shell side and / or the console has at least two, at least three, at least four, at least five, at least six or at least seven raised sections and recessed sections.

[0017] A further advantageous aspect of the description provides that the shell side and / or the console has at least one protruding toothed strip facing the shell side or the console. Due to the toothed strip protruding compared to the inner wall and / or the shell side, better force transmission between the structural support and the console can be ensured. In the case of a corrugated inner wall, toothed strips can be omitted if necessary. The toothed strips can be formed integrally with the console or separately from the console. The toothed strips are preferably screwed and / or welded and / or glued to the console. If there is little concrete cover on the shell side of the structural support, e.g. due to a shift in the reinforcement in the structural support, the toothed strips can have a lower tooth height so that there is still sufficient space along the shell side to accommodate the casting compound.

[0018] A further advantageous aspect of the description provides that, in the supported state, the at least one toothed strip of the bracket is arranged in the region of the at least one recessed section and / or in the region of the at least one raised section of the structural support. It is further advantageous if, in the supported state, the at least one raised section of the bracket and / or the toothed strip of the bracket engages at least in one recessed section of the shell side. This further ensures improved force transmission between the structural support and the bracket.

[0019] An advantageous aspect of the description provides that, in the supported state, the first tensioning device extends perpendicular to the support axis and / or wherein, in the supported state, the force transmission device, in particular the second tensioning device, extends parallel to the support axis. Accordingly, the first tensioning device can be used to press the bracket against the shell side of the structural support. The second tensioning device preferably serves to press the structural support upwards or relieve the load.

[0020] An advantageous aspect of the description provides that the at least one first clamping device has at least one rod, in particular at least one threaded rod, and at least one clamping element, in particular at least one screw nut. The threaded rod extends radially outward with respect to the support axis beyond the bracket, in particular its outer wall. The clamping element can be arranged, in particular screwed, on the free end of the threaded rod in order to apply the first force component to the bracket towards the shell side. In the supported state, the one or more brackets are preferably arranged between the clamping elements, in particular the screw nuts.

[0021] The support device preferably comprises a first bracket and a second bracket formed separately from the first bracket. In the supported state, the structural support is preferably arranged between the first bracket and the second bracket.

[0022] An advantageous aspect of the description provides that, in the supported state, the at least one first tensioning device pre-tensions the first bracket and the second bracket in a clamp-like manner against the shell side of the structural support. The first tensioning device, in particular the threaded rod, extends radially outwards beyond the outer walls of the brackets perpendicular to the support axis. A tensioning element can be arranged at the respective free end of the first tensioning device; in particular, a screw nut can be screwed onto the respective free end of the threaded rod. In this way, the brackets are pressed against one another and against the structural support. This forms a particularly rigid clamp construction which is optimally suited for transmitting forces between the structural support and the support device.

[0023] The object underlying the invention is also achieved by a bracket with the features of claim 9. The invention is directed to a bracket for a previously described support device with a base body. The base body comprises an inner wall facing the shell side and running parallel to a yz-plane, an outer wall facing away from the support axis, opposite the inner wall and running parallel to the yz-plane, a bracket ceiling connecting the inner wall and the outer wall and running parallel to an xy-plane, a bracket base connecting the inner wall and the outer wall and running parallel to the xy-plane, and at least one first intermediate wall arranged between the inner wall and the outer wall and running parallel to the xy-plane (horizontally) and / or at least one second intermediate wall arranged between the inner wall and the outer wall and running parallel to the xz-plane (vertically).

[0024] The bracket has at least one recess on or in the inner wall and at least one recess on or in the outer wall for accommodating clamping devices for applying a first force component to a structural support, which runs perpendicular to the outer side of the structural support. Preferably, the at least one recess in the inner wall and the outer wall are aligned, in particular parallel to the x-axis.

[0025] Alternatively, the console, in particular the console ceiling, the console base, and / or the first partition wall, is trapezoidal in a viewing direction parallel to the z-axis. It is advantageous if a panel width of the outer wall is larger than a panel width of the inner wall. In this case, it is advantageous if only the outer wall has at least one recess for accommodating at least one clamping device.

[0026] The bracket is preferably designed as a welded construction, in particular as a welded steel construction. The bracket is preferably made of high-strength steel. The bracket is preferably designed as a frame. The bracket is therefore designed as a rigid structure that can optimally transfer forces from the structural support and / or the ceiling and / or the floor and / or introduce them into the structural support and / or the ceiling and / or the floor.

[0027] The bracket preferably comprises a receiving area, in particular on the inner wall, for receiving an intermediate layer, in particular casting compound, connecting the at least one bracket and the building support in the supported state.

[0028] The bracket, in particular the base body, preferably has one, in particular two, spacer elements which protrude from the inner wall and / or are arranged between the inner wall and the shell side in the supported state. This ensures that an intermediate space is provided between the bracket and the shell side into which a casting compound can be poured. The intermediate wall can alternatively be designed to be complementary to the shell side. The inner wall of the base body is preferably formed onto the shell side of the building support. The inner wall can preferably be flat if the shell side is flat. The inner wall can preferably be curved, in particular circular, if the shell side is curved, in particular circular. The inner wall can alternatively be wave-shaped.

[0029] Alternatively, the bracket can be configured on the inner wall to correspond to the shell side and / or without spacers. A gap for accommodating an intermediate layer, in particular a potting compound, can be provided by arranging the bracket at a distance from the shell side before the intermediate layer, in particular the potting compound, is applied and / or cured.

[0030] The object underlying the invention is also achieved by a support arrangement with the features of claim 10. The invention is directed to a support arrangement for load support of a storey, the support arrangement comprising: the building support, which connects a ceiling of the storey and a floor of the storey and which extends along a support axis; at least one bracket, which is arranged on a shell side of the building support extending substantially parallel to the support axis; at least one first tensioning device, which is designed to apply a first force component, running perpendicular to the support axis, to the at least one bracket towards the shell side; at least one force conduction device, which is designed separately from the ceiling and the floor and is designed to apply a second force component, running parallel to the support axis, to the at least one bracket.

[0031] The structural column has a column base and a support area. The column base and the support area are preferably arranged between the floor and the ceiling. The column base is preferably adjacent to the floor. The column base is preferably arranged between the support area and the floor.

[0032] The support device is arranged in the support area in such a way that the column base is exposed, in particular for reprofiling. The building column is therefore securely supported, with no or only a small load being transferred through the column base and a large or entire load being transferred into the ground through the force introduction device. In addition, the special design of the support arrangement makes the column base easily accessible, so that reprofiling of the column base can be carried out easily and safely. Preferably, the force transmission device is designed as a second clamping device, in particular as a hydraulic and / or pneumatic and / or mechanical press. The second clamping device can be arranged on a profile block, in particular a profile block made of steel.The power transmission device can additionally or alternatively be designed as a load-bearing element, in particular as a support and / or an intermediate ceiling and / or a guideway of an indoor crane.

[0033] It is advantageous if, in the supported state, an intermediate space is formed which is delimited by the bracket and the structural support. It is additionally or alternatively advantageous if an intermediate layer is provided which is arranged between the at least one bracket and the shell side and which connects the bracket and the shell side in a force-fitting and / or form-fitting and / or material-fitting manner. It is further advantageous if, in the supported state, the intermediate layer is arranged in the intermediate space. The intermediate layer can be designed as a casting compound. The casting compound is preferably flowable and / or curable. The intermediate layer can additionally or alternatively be designed as an adhesive layer and / or plastic layer, in particular a hard rubber layer.

[0034] The object underlying the invention is also achieved by a method having the features of claim 11. The invention is directed to a method for load introduction and / or load transfer on a structural support on a structural support which is to be supported and / or repaired and / or extended and which extends along a support axis, the method comprising the steps of: arranging at least one bracket on the shell side, applying a first force component to the at least one bracket, wherein the first force component is directed perpendicular to the support axis to the shell side, applying a second force component to the at least one bracket, wherein the second force component runs parallel to the support axis.

[0035] It is advantageous if, before applying the first force component, a casting compound is poured into at least one gap defined by the bracket and the structural support. Furthermore, it is advantageous if the first force component and / or the second force component are applied after the casting compound has hardened.

[0036] The second force component is preferably formed by a second tensioning device or by a load-bearing element placed or supported on the support device, in particular the console, preferably a console ceiling of the console. Alternatively, the load-bearing elements can be suspended from the console, in particular the console floor.

[0037] An advantageous aspect of the description provides that, prior to arranging the bracket on the shell side, the shell side of the structural support is texturing and / or profiling and / or structuring. For texturing, the shell side can be machined using a high-pressure water jet. For profiling, at least one, preferably several recessed sections can be machined into the shell side of the structural support, in particular using a chisel or a saw.

[0038] A further advantageous aspect of the description provides that, before arranging the bracket on the shell side, a recording of the arrangement of reinforcement in the structural column is carried out (reinforcement scan). Subsequently, at least one toothed strip is selected depending on the arrangement of the reinforcement in the structural column or the reinforcement scan. The selected at least one toothed strip is then attached to an inner side of the at least one bracket facing the structural column in the supported state. Consequently, even with a shallow concrete cover and / or with reinforcement protruding from the shell side, a sufficient gap is provided to accommodate the casting compound.

[0039] An advantageous aspect of the description provides that after the console has been arranged and the first force component and the second force component have been applied to the structural column, the exposed column base is reprofiled.

[0040] It is advantageous if the first force component is applied flatly to an outer wall of the bracket and / or acts on an inner wall of the bracket and the shell side of the structural support. For example, the first force component can be introduced by a plurality of first clamping devices, in particular threaded rods, spaced apart along the support axis, wherein the brackets are pressed towards one another and against the structural support by two clamping elements, in particular by screw nuts. It is further advantageous if the second force component is applied to a bracket base of the bracket or to a bracket ceiling of the bracket. For example, the second force component can be introduced by a hydraulic press acting on the bracket base. A second clamping device is preferably provided for each bracket, each of which acts on the bracket base of the bracket.The first clamping device or devices can be used together to form the first force component on both consoles.

[0041] Due to the distance between the second tensioning device and the structural support, the brackets may spread when supported. This causes the bracket to shift away from the structural support, particularly on the side where the second tensioning device is engaged. If the second tensioning device engages the bracket base, the brackets may spread in the area of ​​the bracket base. To counteract this, the first tensioning devices, in particular the threaded rods and the tensioning elements, are tensioned differently along the support axis. It is advantageous if the tension of the first tensioning device increases towards the side where the second tensioning device is engaged. If the second tensioning device is arranged at the bracket base, the first tensioning devices are more strongly tensioned in the area of ​​the bracket base than in the area of ​​the bracket ceiling. The tension can be distributed gradually along the support axis.It is conceivable that there is a preload zone for each threaded rod, with an individual preload force being applied to each preload zone by the threaded rods and the screw nuts.

[0042] An advantageous aspect of the description provides that a design of the support device, in particular the determination of at least one output variable characterizing the support device, is carried out as a function of at least one input variable characterizing the boundary conditions of the structure and / or the structural support. The input variables preferably include the column load of the structural support and / or the concrete compressive strength of the structural support and / or the cross-sectional dimension of the structural support and / or the concrete compressive strength of the soil.The output variables preferably include the console dimension and / or the height of the console and / or the width of the console and / or the depth of the console and / or the height of the intermediate layer, in particular the casting compound, and / or the width of the intermediate layer, in particular the casting compound, and / or the depth of the intermediate layer, in particular the casting compound, the texturing and / or profiling of the shell side and / or the console and / or the number of first clamping devices and / or the height of the first force component and / or the distribution of the first force component over the individual threaded rods and / or the number of second clamping devices and / or the height of the second force component and / or the support surface of the second clamping devices and / or the distance between the second clamping devices and the shell side.

[0043] Further advantages, features, and details will become apparent from the following description, which illustrates various embodiments of the invention with reference to the drawings. The features mentioned in the claims and the description may be essential to the invention individually or in any combination.

[0044] They show: Fig. 1 shows a schematic side view of a storey with a structural support, which is supported by a support device according to the invention; Fig. 2 shows a schematic side view of two stores, each with a structural support, wherein the upper structural support is supported by a support device according to the invention and the lower structural support is supported by a support / portal frame known from the prior art; Fig. 3 shows a horizontal sectional view of the structural support and a support device according to the invention with two brackets according to a first embodiment; Fig. 4 shows a horizontal sectional view of the structural support and a support device according to the invention with two brackets according to a second embodiment; Fig. 5 shows a schematic side view of the structural support with incorporated raised and recessed sections; Fig.Fig. 6 shows a detailed view of the raised and recessed sections with a toothed strip of the bracket arranged in a recessed section; Fig. 7 shows schematic detailed views of a recessed section with different concrete cover of the structural support and toothed strips with different tooth heights used for this purpose; Fig. 8 shows a side view of a one-sided support device with a bracket; Fig. 9 shows a horizontal sectional view of a support device according to . Fig. 8 ; and Fig. 10 a schematic side view of a support device for supporting and / or supporting at least one load-bearing element.

[0045] The Fig. 1The building shown has a first floor 10, in particular an underground garage, with a ceiling 12 and a floor 14. Furthermore, the building has a structural column 16, which supports the ceiling 12 and transfers the force resulting from the load into the floor 14. The structural column 16 extends between the ceiling 12 and the floor 14 of the floor 10. The structural column 16 can be designed as a concrete pillar or reinforced concrete column, which must be repaired after damage to the column base 18. During the repair of the column base 18, the structural column 16 must be supported by means of an additional device. Fig. 1 the exposed column base 18 is shown, which can then be reprofiled by means of a grout or shotcrete.

[0046] The structural support 16 extends according to Fig. 1along a support axis 20, which runs vertically and along a z-axis. The ceiling 12 and the floor 14 run horizontally, perpendicular to the support axis 20 and parallel to a plane spanned by an x-axis and a y-axis. The x-axis, the y-axis, and the z-axis are each arranged perpendicular to one another. Alternatively, it is conceivable for the ceiling 12 and / or the floor 14 to be inclined, e.g., in the case of a ramp.

[0047] According to Fig. 1 A support device 22 supports the structural column 16 in a supported state. The support device 22 is arranged on a shell side 24 of the structural column 16. The shell side 24 has a support region 26, which is arranged above the column base 18. The support device 22 is arranged in the support region 26 on the shell side 24, so that the column base 18 is exposed for reprofiling. The column base 18 is then reprofiled.

[0048] The structural support 16 is in accordance with Figs. 3 and 4 rectangular in cross-section along the support axis 20. In this case, the structural support 16 has four shell side regions, which are preferably arranged parallel to an xz plane or a yz plane. Alternatively, it is conceivable for the cross-section of the structural support 16 to be square. Alternatively, it is conceivable for the cross-section of the structural support 16 to be round, in particular oval or circular. In this case, the shell side regions extend along curved surfaces parallel to the z-axis.

[0049] The support device 22 has a first bracket 28 and a second bracket 30. It is also conceivable that three or four brackets are provided. The first bracket 28 and the second bracket 30 are each designed as frame-like, rigid structures, in particular welded steel structures. The support device 22 further has a first tensioning device 32 for applying a first force component 34 to the first bracket 28 and the second bracket 30 against the shell side 24 of the structural support 16, wherein the first tensioning device 32 is arranged according to Fig. 5five threaded rods 36 extending perpendicular to the support axis 20 and two screw nuts 38 at the free ends of each threaded rod 36. In addition, the support device 22 has two second clamping devices 40 for applying a second force component 42, each running parallel to the support axis 20, to the first bracket 28 and the second bracket 30. The second clamping device 40 is preferably designed as a press 44, in particular a hydraulic press, which is arranged on a profile block 46.

[0050] By means of the first tensioning device 32, the first bracket 28 and the second bracket 30 are clamped against the structural support 16 in a clamp-like manner. In addition, the first bracket 28 and the second bracket 30 are each clamped parallel to the shell side 24 using the second tensioning device 40. In the supported state, this leads to the superposition of the first force component 34 and the second force component 42, which opposes the force transmission from the structural support 16. This ensures that the force can be dissipated via the support device 22 in the support area 26 of the structural support 16 and then introduced into the ground 14 via the support device 22. In this case, the column base 18 does not have to bear any load, so that concrete removal and reprofiling can be carried out at the column base 18.

[0051] To further securely connect the structural support 16 and the first bracket 28 and the second bracket 30, a flowable and curable casting compound 48 is poured into a gap 50, wherein the gap 50 is delimited by the shell side 24 and the first bracket 28 and by the shell side 24 and the second bracket 30. The casting compound 48 ensures surface contact between the support device 22 and the shell side 24, thus ensuring evenly distributed force transmission. To form the gap 50, spacer elements 52 can be arranged on the brackets 28, 30, in particular on their inner walls. Alternatively, the brackets 28, 30 can initially be arranged at a distance from the shell side 24 and then fixed in position using the casting compound 48. In the supported state, the structural support 16 is arranged between the first bracket 28 and the second bracket 30.The first bracket 28 and the second bracket 30 can each be arranged on opposite shell side regions of the shell side 24.

[0052] The brackets 28, 30 each have a base body 54, wherein the base body 54 has an inner wall 56 facing the shell side 24 in the supported state and a remote outer wall 58 opposite the inner wall 56. Furthermore, the base body 54 has an upper bracket ceiling 60 connecting the inner wall 56 and the outer wall 58 and a lower bracket base 62 connecting the inner wall 56 and the outer wall 58. For further stiffening, a plurality of intermediate walls 64 can be arranged between the inner wall 56 and the outer wall 58 and between the bracket ceiling 60 and the bracket base 62, wherein at least one first intermediate wall 64A runs parallel to an xy plane and at least one second intermediate wall 64B runs parallel to an xz plane.

[0053] According to Fig. 3the inner wall 56, the outer wall 58, the console ceiling 60, the console floor 62 and / or the first intermediate wall 64A each have a panel width running parallel to the y-axis, which is of the same design. Fig. 4 the plate width of the inner wall 56 is smaller than the plate width of the outer wall 58.

[0054] Preferably, the panel width of the inner wall 56 corresponds to the column width of the structural column 16 to be supported, with the column width running parallel to the y-axis. Accordingly, the console ceiling 60, the console floor 62, and the first intermediate wall 64A are trapezoidal, with the respective panel width decreasing from the outer wall 58 toward the inner wall 56.

[0055] Alternatively, the threaded rods 36 can be Fig. 8 and 9in the supported state, extend through the structural support 16. For this purpose, holes are first drilled in the structural support 16 and the threaded rod 36 is inserted. The threaded rods 36 are then fastened and the brackets 28, 30 are subjected to the first force component by means of the threaded rods 36 and the screw nuts 38 with the aid of a hydraulic tensioning tool, and then the holes are filled. If toothed strips 72 are provided on the bracket 28, 30 in the area of ​​the threaded rod 36 in this case, these can be interrupted to allow the threaded rods 36 to pass through. Alternatively, it is conceivable that the toothed strips 72 and the threaded rods 36 alternate along the vertical extent of the bracket 28, 30 running parallel to the support axis 20.

[0056] According to Figs. 3 and 4In the supported state, the first clamping device 32, in particular the threaded rods 36, extends perpendicular to the support axis 20 beyond the outer walls 58 of the brackets 28, 30. The first clamping device 32 extends through a recess 66 in the outer wall 58 of the first bracket 28 and through a recess 66 in the outer wall 58 of the second bracket 30. In the supported state, the recesses 66 of the first bracket 28 and the second bracket 30 are arranged at a common height, so that the first clamping device 32 runs perpendicular to the support axis 20 and horizontally, respectively. To fasten the brackets 28, 30, screw nuts 38 are screwed onto the free ends of the threaded rods 36, and thus, in particular by means of a hydraulic clamping tool, the brackets 28, 30 are clamped against one another and fastened to the structural support 16.In the supported state, the brackets 28, 30 and the structural support 16 are arranged between the tensioning elements, in particular the screw nuts 38. According to . Fig. 5 Ten threaded rods 36 and 20 screw nuts 38 are provided, whereby due to the perspective only five threaded rods 36 are visible. The first clamping device 32 is according to Figs. 3 and 4 In the supported state, they are spaced apart along the y-axis from the structural support 16. The threaded rods 36 are arranged at least in sections within the brackets 28, 30, in particular between two first partition walls 64A. The threaded rods 36 are also arranged at a distance from one another parallel to the z-axis.

[0057] In Fig. 3 In the inner wall 56, corresponding to the outer wall 58, recesses 66 are also provided through which the first clamping device 32 extends. In Fig. 4the inner wall 56 has a smaller plate width, so that here the first clamping device 32 is also formed at a distance from the inner wall 56 along the y-axis.

[0058] To further improve the force transmission between the structural support 16 and the support device 22, raised sections 68 and / or recessed sections 70 can be provided in the shell side 24 of the structural support. The casting compound 48 is preferably also arranged in the recessed sections 70. In addition, the brackets 28, 30, in particular the inner side of the inner walls 56 facing the shell side 24, can have toothed strips 72, which are arranged in the region of the raised sections 68 and / or in the region of the recessed sections 70 in the supported state. The toothed strips 72 preferably engage at least partially in the recessed sections 70, thus enabling a further improvement in force transmission. The raised sections 68 and recessed sections 70 can be produced by texturing and / or profiling and / or structuring the shell side 24. According to Fig. 5The recessed sections 70 extend parallel to the y-axis and / or are arranged at a distance from one another parallel to the z-axis. Raised sections 68 and recessed sections 70 alternate parallel to the z-axis.

[0059] To manufacture the support device 22, the brackets 28, 30, the threaded rods 36, the screw nuts 38, the presses 44, and preferably the profile blocks 46 are provided. The brackets 28, 30 are previously welded from high-strength steel plates, resulting in a rigid, frame-like base body 54.

[0060] To prepare the structural support 16, raised sections 68 and / or recessed sections 70 can be provided in the shell side 24. The recessed sections 70 can be introduced into the shell side 24, for example, by means of high-pressure water jets or chiseling or sawing.

[0061] The brackets 28, 30 are then arranged in the support area 26 of the structural supports 16. A gap is left between the shell side 24 and the inner wall 56 by arranging the brackets 28, 30 at a distance from the shell side 24. A casting compound 48 is poured into this gap 50, which additionally connects the structural support 16 and the brackets 28, 30 in a form-fitting and / or material-fitting manner. Once the casting compound 48 has hardened, the brackets 28, 30 are subjected to a first force component 34 by means of the threaded rods 36 and the screw nuts 38, thereby clamping them together and force-fittingly fastening them to the structural support 16. Then, the brackets 28, 30 are each subjected to a second force component 42 by a press 44 arranged on a profile block 46 parallel to the support axis 20. The presses 44 further clamp the brackets 28, 30 parallel to the support axis 20.Accordingly, a force can be transferred from the structural support 16 and a force can be introduced into the ground 14 by means of the support device 22.

[0062] The brackets 28,30 can alternatively rest against the shell side 24 by means of the spacer elements 52, so that a gap 50 is formed between the shell side 24 and the inner walls 56 of the brackets 28,30.

[0063] In this supported state, the column base 18 can be removed and reprofiled. Once the repair of the structural column 16 is complete, the support device 22 can be removed so that the ceiling 12 is again supported by the repaired structural column 16. The casting compound 48 adhering to the shell side 24 can then be removed.

[0064] It is conceivable that, in the supported state, the console ceilings 60 are formed parallel to the z-axis and spaced from the ceiling 12. It is further conceivable that a casting compound 48 can be provided between the console ceiling 60 and the ceiling 12 in order to connect them.

[0065] To further improve the connection between the structural support 16 and the brackets 28, 30, a force-fitting and / or form-fitting and / or material-fitting connection can also be provided. For this purpose, at least one toothed strip 72 extending parallel to the y-axis is arranged on the inner walls of the brackets 28, 30, each of which engages a recessed section 70 of the shell side 24.

[0066] The second clamping devices 40 and / or the profile blocks 46 are arranged such that the column base 18 is accessible for concrete removal and reprofiling. The second clamping devices 40 are arranged at a distance from the structural column 16. This results in a moment acting on the brackets 28, 30 in the supported state, which causes the support device 22 to spread open or the brackets to be removed from the shell side 24. To counteract this, the first clamping device 32, in particular the threaded rods 36 and the screw nuts 38, can be differently clamped parallel to the z-axis, in particular by means of a hydraulic clamping device. It is advantageous if the first force component 34 increases towards the second clamping device 40 and thus counteracts the acting moment. According to the Fig. 1, 2 and 5The second clamping device 40 supports the console base 62 of the consoles 28, 30. Accordingly, the first force component 34 caused by the first clamping device 32 would increase from the console ceiling 60 to the console base 62. In other words, the screw nuts 38 are tightened more tightly in the area of ​​the console base 62 than in the area of ​​the console ceiling 60. Preferably, the change in the first force component 34 toward the console base 62 is gradual.

[0067] For further preparation, a reinforcement scan can be performed on the structural column 16, in which the arrangement of a reinforcement 74 on or within the structural column 16 is recorded. The concrete cover is also determined. If, for example, the reinforcement 74 has slipped within the structural column 16 during manufacture, the reinforcement 74 is not arranged centrally in the structural column 16. Therefore, when recessed sections 70 are introduced into the shell side 24, the reinforcement 74 may become visible or protrude. In order to continue to provide an intermediate space 50 to accommodate a sufficient amount of casting compound 48 in this area, toothed strips 72 can be provided on the inner walls with lower tooth heights according to Fig. 7 Accordingly, toothed strips 72 are attached to the inner wall 56 depending on a previously performed reinforcement scan.

[0068] In Fig. 2A first floor 10 and a second floor 76 arranged below the first floor 10 are shown, wherein the floor 14 of the first floor forms the ceiling 12 of the second floor 76. In the floors 10, 76, two building supports 16 arranged one above the other along the z-axis are to be repaired. For this purpose, it is conceivable that both building supports 16 are each supported by a support device 22. Alternatively, according to Fig. 2It is advantageous if the structural support 16 of the first floor is supported by the support device 22, and the structural support 16 of the second floor 76 is supported by any supports 78, in particular supports 78 and / or portal frames known from the prior art. The second clamping devices 40 and the supports 78 and / or portal frames are each arranged one above the other parallel to the z-axis. This ensures optimal force dissipation from the structural support 16 of the first floor and force introduction into the floor 14 of the second floor 76 via the support device 22 and the supports 78.

[0069] Alternatively, the support device 22 can be Fig. 10be used to subsequently arrange or support a load-bearing element 80, such as a beam, a suspended ceiling, or a guideway of a hall crane, on existing structural supports 16. The load-bearing element 80 can be arranged permanently or temporarily on the structural support 16. If a ceiling 12 does not have sufficient load-bearing capacity, it can be reinforced by means of a beam. For this purpose, the bracket 28, 30 is arranged according to Fig. 10(left of the structural support 16) on the structural support 16 and a first force component is applied thereto by means of the first clamping devices 32. Previously, the bracket 28, 30 can be connected to the shell side 24 of the structural support 16, preferably with an intermediate layer 48, in particular a casting compound, in a force-locking and / or form-locking and / or material-locking manner. The attached bracket 28, 30 serves as a support element for supporting the beam, wherein the beam is preferably placed on the bracket ceiling 60 of the bracket 28, 30. Between the beam and the ceiling 12, a further intermediate layer, in particular a further casting compound, can preferably be provided, so that the force from the ceiling 12 is transferred via the beam into the bracket 28, 30 and then introduced into the structural support 16. In this case, the beam forms the load-bearing element 80. In a further case, according to Fig. 10(to the right of the structural support 16), a suspended ceiling or a guideway of a hall crane is placed. This arrangement differs from the arrangement with the girder in that the suspended ceiling or the guideway is arranged at a distance from the ceiling 12. It is of course conceivable that only one bracket 28, 30 is provided on the structural support 16. In this case, it was illustrated that several load-bearing elements 80 can also be supported with one support device 22.

[0070] Furthermore, according to Fig. 8 and 9It is conceivable that the support device 22 has only one bracket 28, 30 and is designed on one side. In this case, an intermediate plate 82 or at least one base plate is located on the side of the shell side 24 facing away from the bracket, which serves to support the first clamping devices 32. The one-sided arrangement is conceivable both for the repair of the building supports and for the extension of the building supports 16 by means of load-bearing elements 80. It should be noted that Fig. 8 and 9 are arranged mirror-inverted to each other. List of reference symbols
