Description

[0001] The invention relates to a device for clamping two components. STATE OF THE ART

[0002] In the construction industry, prefabricated components are typically used, which are then assembled and installed on-site. This usually necessitates adjusting the position of the components relative to one another. For example, a wooden wall might have a slight deviation from its intended geometry, which can manifest as surface curvature. If the wooden wall is placed orthogonally onto a floor slab, this undesirable deviation causes it to deviate from the intended parallel alignment with the slab edge. As a result, the wall, already mounted on the slab at one point, will be oriented with its edge furthest from the initial mounting point towards the center of the slab or away from the slab edge. This deviation requires correction, for which auxiliary equipment is needed due to the resulting distortion forces.

[0003] German patent DE 20 2013 006 280 U1 discloses a beam tensioning device suitable for bracing structural components. Regardless of the fact that the components may be damaged when using this beam tensioning device, it is not suitable for transmitting compressive forces.

[0004] The present invention is based on the objective of creating a device that can be used to correct the position of components using both tensile and compressive forces. This objective is achieved by a device according to the proposed claim 1.

[0005] Further advantageous details and embodiments of the invention, as well as further developments and variants, can be seen from the dependent claims and the drawing explained below.

[0006] According to the invention, a device for clamping two components is proposed, with two clamping feet that are linearly movable relative to each other, wherein one clamping foot can be attached to the first component and the other clamping foot can be attached or stopped to the second component, and the linear movement of both clamping feet is effected via a common threaded spindle which can be actuated by a ratchet.

[0007] The invention is characterized in that the threaded spindle is received on both sides in bearing blocks, each of which is arranged in a thrust-resistant manner on the upper side of a base plate of the respective clamping foot. The threaded spindle has a left-hand thread on one side and a right-hand thread on the other, and the bearing blocks have internal threads corresponding to the external threads of the threaded spindle. The rotational movement of the threaded spindle causes a linear movement of the clamping feet, which, depending on the set direction of rotation of the ratchet, moves the clamping feet towards each other or away from each other. Because the threaded spindle is received in the bearing blocks, its axis of rotation is spaced away from the upper side of the underlying component, thus preventing deflection of the clamping feet caused by opposing forces.It has proven particularly advantageous if the clamping foot, located near the component to be corrected, has an angled plate that is aligned orthogonally to the base plate. This then acts as a large-area stop on the component and distributes the clamping force over the surface of the angled plate, thus preventing damage that would otherwise be caused by point loads.

[0008] Means are provided to mechanically fasten the clamping feet to the components to be clamped. This enables a controlled connection that, unlike clamping claws, protects the components. Where movement of the clamping feet is required during the clamping process, the necessary clearance is provided by elongated holes. Otherwise, the openings provided for fasteners are free of play.

[0009] Further advantages and advantageous embodiments of the invention can be found in the following description, the drawing, and the claims. There are various ways to advantageously develop and further refine the teaching of the present invention. For this purpose, reference should be made, on the one hand, to the dependent claims and, on the other hand, to the following explanation of an exemplary embodiment of the invention with reference to the drawings.

[0012] The entirety in the Fig. 1 and Fig. The device 1 shown in Figure 2 has two clamping feet 10 and 20 that are movable linearly relative to each other. Each clamping foot 10 and 20 consists of a base plate 11, 21, on the upper surface 12, 22 of which a bearing block 15, 25 is arranged. The bearing blocks 15, 25 are securely attached to the respective base plate 11, 21. Optionally, the base plate 11, 21 and the bearing block 15, 25 can also be formed in one piece. The first clamping foot 10 additionally has an angle plate 17. Both clamping feet 10, 20 are connected by a threaded spindle 40, the ends of which are screwed into one of the bearing blocks 15, 25. For this purpose, the bearing block 15 of the first clamping foot 10 has an internal left-hand thread 16 and the bearing block 25 has an internal right-hand thread 26. Accordingly, the threaded spindle 40 has an external left-hand thread 41 on one side and an external right-hand thread 42 on the other. Between the two threaded sections 45, 46 (see...) Fig. 9) A force-fit point 50 in the form of an external hexagon is located. The force-fit point 50 is enclosed by a reversible ratchet 90. Depending on the selected position, the direction of rotation of the threaded spindle 40 is determined, while in the opposite direction, a freewheel is present.

[0013] The Fig. Figures 3 to 5 show the first clamping foot 10 from different views. This consists of the base plate 11, the bearing block 15, and the angle plate 17. The drawings do not show the type of connection between the bearing block 15 and the base plate 11. Both screw and welded connections, or a one-piece design, are suitable. It is important that the bearing block 15 is securely mounted on the upper surface 12 of the base plate 11, as the positioning movement from the threaded spindle 40 is transmitted to the clamping foot 10 via this block. The base plate 11 has openings 13 in the form of elongated holes for fasteners to fix it to a component. Similar openings 19 are provided in the angle plate 17. The bearing block 15 has a bearing bore 18 in which the internal left-hand thread 16 is machined.

[0014] The Fig. Figures 6 to 8 show the second clamping foot 20 from different views. It has the same construction as the first clamping foot 10 and consists of the base plate 21 and the bearing block 25 arranged on the upper surface 22, but without the angle plate. The type of connection between the bearing block 25 and the base plate 21 is not shown in these drawings either, as screw connections, welded connections, or a one-piece design are all suitable. In any case, the bearing block 25 is securely mounted on the base plate 21 and transmits the positioning movement from the threaded spindle 40 to the clamping foot 20. The base plate 21 has openings 23 for fasteners to fix it to a component.

[0015] The bearing block 25 has a bearing bore 28 in which the internal right-hand thread 26 is machined.

[0016] The Fig. 9 and Fig. Figure 10 shows the threaded spindle 40. This consists of two threaded sections 45 and 46, between which a force application 50 in the form of an external hexagon is arranged. The first threaded section 45 has an external left-hand thread 41, while the second threaded section 46 has an external right-hand thread 42.

[0017] The Fig. Figures 11 to 16 show an application example of the present invention. A wooden wall 70 is placed on a floor slab 60, which can be a wooden or concrete floor, and is already partially fixed with appropriate fastening means 80.

[0018] In Fig. Figure 13 shows the undesired deflection “A”. The wooden wall 70 has a slight distortion here, which can be corrected with the device 1 according to the invention. For this purpose, the device 1 is mounted on the floor slab 60 with its second clamping foot 20. The starting position of the threaded spindle 40 is chosen such that both clamping feet 10, 20 have the smallest possible distance “D” from each other and the first clamping foot 10 with its angle plate 17 rests against the inside 71 of the wooden wall 70. Now the ratchet 90 is actuated, whereby the rotational movement of the threaded spindle 40 occurs only in one direction according to the setting, and a freewheel occurs during the opposite ratchet movement, as is known. During the rotational movement of the threaded spindle 40, both clamping feet 10, 20 are moved linearly apart in the directions X and Y by the opposing left- and right-hand threads.Since the clamping foot 20 is fixed to the floor slab 60, the first clamping foot 10, due to the linear distance to the second clamping foot 20, presses the wooden wall 70 towards the edge 62 of the floor slab 60 during spindle movement. If the resulting lateral forces exert too much pressure on the device 1, the first clamping foot 10 can also be fixed as a temporary measure, whereby the elongated holes still allow for some freedom of movement.

[0019] In the Fig. The desired final mounting position of the wooden wall 70 is reached between 14 and 16. This is due to the increased distance D. v between the two clamping feet 10, 20 is visible, and final fixing can take place.

[0020] Once the components have been brought into their final position, they are fixed in place using suitable mechanical fasteners, which are not shown here.
