Description

[0001] The invention relates to a device for longitudinally connecting vertically oriented structural elements such as supports and / or posts that are separated by a ceiling element. STATE OF THE ART

[0002] In timber and post-and-beam construction, columns, posts, or uprights are predominantly vertically oriented structural elements. The length of these elements, limited by manufacturing processes or by separating elements such as ceilings, is often unfavorable from a structural engineering perspective.

[0003] EP 2 801 682 B1 describes a column base with height adjustment. The column base has a connecting plate for attaching it to a column. Axial loads must be absorbed and transferred through the threaded flanks. These are unfavorable factors for structural analysis. An axial connection between two columns is not possible with the described column base. TASK STATEMENT

[0004] The present invention is based on the objective of creating a device that enables axial extension of vertically oriented structural elements, such as posts or supports.

[0005] This problem is solved by a device according to the proposed claim 1.

[0006] 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. ADVANTAGES OF THE INVENTION

[0007] According to the invention, a device for longitudinally connecting vertically oriented structural elements such as columns and / or posts, which are separated by a ceiling element, is proposed.

[0008] The invention is characterized by a coaxial coupling penetrating the ceiling element, which carries a base plate at its first free end and a head plate at its second free end for connection with the respective adjacent component, wherein the base plate is arranged on a telescopic cylinder and the head plate on a piston and the piston is axially displaceable within the telescopic cylinder.

[0009] The invention provides a post extension that enables the connection of posts between the ceiling. This creates a point-supported ceiling system, suitable for single-family homes as well as high-rise and multi-story buildings. The invention reduces the need for additional beams or crossbeams, thereby saving time and materials.

[0010] The invention provides that a pressure plate and an insulating element are arranged between the base plate and the ceiling element to be placed upon it. The insulating element rests on the pressure plate. Preferably, the pressure plate rests on the top of the base plate. This ensures optimal force transmission to the posts. At the same time, the insulating element acts as a separator, particularly providing impact sound insulation between the floors.

[0011] It has proven particularly advantageous to insert the base plate, pressure plate, and insulation element into a milled recess in the lower, vertically oriented component. This provides optimal guidance for the components.

[0012] The invention advantageously provides that the base plate is mechanically connected to the lower vertically oriented component by means of screws and that the head plate is mechanically connected to the upper vertically oriented component by means of screws, wherein the screws pass through the base plate and the head plate in an inclined screw axis and cut into the components.

[0013] Preferably through 30-degree bores in the base and head plate, the screws are guided at an angle, thus guaranteeing optimal force transmission in all directions.

[0014] The invention provides that the portion of the telescopic sleeve protruding from the ceiling element is enclosed by a centering plate, which is mechanically fastened to the ceiling element with screws. This supports the coaxial fixing of the posts.

[0015] A particularly preferred embodiment of the invention provides that the piston inserted in the telescopic sleeve is locked by a pin that extends transversely through the telescopic sleeve and the piston. This prevents any movement between the piston and the sleeve. The components are dimensioned such that a secure fit is ensured without transferring the weight load to the pin.

[0016] To prevent lateral compression failure and optimize the vertical force transmission between the supports, the coaxial coupling according to the invention is designed as a steel core. Galvanized structural steel S355 has proven effective for this purpose.

[0017] 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 drawing.

Fig. 35 Assembly step 9 Inserting the locking bolt and Fig. 36 the completed assembly.

[0020] The Fig. 1 and Fig. Figure 2 shows the device according to the invention. This comprises a coaxial coupling 1 with means arranged at its free ends 2 and 3, which provide an end-face connection of the vertically oriented and ceiling elements 93 ( Fig. 2) separate components 90, 91 ( Fig. 2) such as supports and posts, wherein the components 90, 91 to be connected are fixed in a coaxial orientation to each other. The means for connecting the components at their ends are a head plate 30, which is screwed to the upper component 91, and a base plate 20, which is screwed to the lower component 90 by means of the screws 99. For this purpose, the head plate 30 is screwed to the base section 96 and the base plate 20 to the head section 95 of the vertically aligned components 90, 91. If necessary, the component can be prepared by a milled recess 89, as is done, for example, in Fig. 2 is shown on the lower component 90. The base plate 20, a pressure plate 50 and a damping element 60 are then inserted into the milled recess 89.

[0021] The coaxial coupling 1 consists of a telescopic cylinder 10 on which the base plate 20 and a piston 11 are mounted ( Fig. 2) on which the head plate 30 is mounted. The piston 11 is axially displaceable within the telescopic cylinder 10 and is locked by a cotter pin 12 that passes orthogonally through the piston 11 and the telescopic cylinder 10, thereby preventing the axial displacement of both components relative to each other.

[0022] As particularly in Fig. As can be seen in Figure 1, the screws 99 have an inclined screw axis. They are preferably guided at an angle of 30°, which guarantees optimal force transmission in all directions.

[0023] The telescopic cylinder 10 is welded to the top 28 of the base plate 20. The welds are either ground down so that no material remains extending beyond the outer circumference of the cylinder, or the diameter of the central opening of the pressure plate 50 is made large enough to allow it to sit flush on the base plate 20.

[0024] The piston 11 is screwed to the head plate 30. For this purpose, a central threaded blind bore 17 is provided in the piston 11, into which a screw 18 is screwed while pressing the head plate 30 against it.

[0025] The device is completed by a centering plate 40, a pressure plate 50, and a damping element 60, which enclose the telescopic cylinder 10. The centering plate 40 is placed on the apex 94 of the ceiling element 93 and fastened to it with the screws 98. The pressure plate 50 and the damping element 60 are located below the ceiling element 93 and are not mechanically fastened.

[0026] The Fig. Figures 3 to 5 show the lower part of the coaxial coupling 1 in the circumference of the telescopic cylinder 10 with the base plate 20 attached to it and the Fig. 6 to 7 the footplate 20 as well as the Fig. Figures 8 to 9 show the telescopic cylinder 10 as individual parts. The telescopic cylinder 10 is a circular cylindrical sleeve which has two opposing through-openings 13, 14 on its side furthest from the base plate 20, which penetrate the wall of the telescopic cylinder 10 and whose central axes 15, 16 extend linearly and coaxially to each other.

[0027] The base plate 21 has the geometric shape of a truncated cone. The conical section 22 rises from an approximately square base 20. The inclination of the conical section also determines the angular position for the screws 99. The longitudinal axis 23 of the boreholes 24 run at an angle α of 90° to the conical surface 25, penetrate the entire base plate 20, and exit at the bottom surface 26. On the entry side, the boreholes 24 are provided with a countersink 27, so that the screw heads of the screws 99 are completely recessed below the conical surface 25.

[0028] The Fig. Figures 10 to 12 show the upper part of the coaxial coupling 1 in the circumference of the piston 11 with the head plate 30 arranged on it and the Fig. 13 and Fig. 14 the footplate 30 as well as the Fig. 15 and Fig. 16 the piston 11 as individual parts.

[0029] The headplate 30 has the same geometry as the footplate 20.

[0030] The conical section 32 rises on an approximately square base 31. The inclination of the conical section also determines the angular position of the screws 99. The longitudinal axis 33 of the boreholes 34 runs at an angle α of 90° to the conical surface 35, passes through the entire head plate 30, and exits at the top surface 36. On the entry side, the boreholes 34 are provided with a countersink 37, so that the screw heads of the screws 99 are completely recessed below the conical surface 35. The head plate 30 differs from the base plate 20 in that it has a central bore 39. This bore leads to a threaded blind hole 41 in the piston 11. On the top surface 36, the bore has a countersink 42, so that the head of the screwed-in screw rests in this recess and is located below the top surface 36.The piston 11 is penetrated by a channel 43, the central axis 44 of which runs coaxially to the passage openings 13 and 14 in the telescopic cylinder 10.

[0031] The Fig. 17 and Fig. Figure 18 shows a pressure plate 50, which is inserted between the lower vertically oriented component and the ceiling element. The pressure plate 50 has a substantially square geometry and features a rounded edge 44 on each of its corners. The pressure plate 50 is penetrated by a central bore 39, which surrounds the telescopic cylinder 10.

[0032] The in the Fig. 19 and Fig. The insulation element 60 shown in Figure 20 has the same shape as the pressure plate 50. Here too, the edges are provided with rounded edges 64. The insulation element also surrounds the telescopic cylinder 10 with its central bore 69. During assembly, the insulation element 60 is positioned between the pressure plate 50 and the ceiling element 93.

[0033] In the Fig. 21 and Fig. Figure 22 shows a centering plate 40. It has the same shape as the pressure plate 50 and also functions as a pressure plate. Here, too, the edges have a rounded edge 45. The centering plate 40 surrounds the telescopic cylinder 10 with its central bore 49. The central bore 49 also serves a centering function. Accordingly, the central bore has a dimension designed to fit the telescopic cylinder. To fix the position, the centering plate 40 has screw holes 46 with countersinks 47 to receive the screws 98, which are driven through the centering plate 40 into the ceiling element 93.

[0034] In the Fig. Figures 23 to 26 illustrate various installation situations. Fig. 23 The coaxial coupling 1 penetrates the ceiling element 93 centrally in the middle. The lower vertically oriented component 90 and the upper vertically oriented component 91 are aligned and fixed in a common longitudinal axis with the aid of the device according to the invention, of which only the centering plate 40 and the telescopic cylinder 10 are visible here.

[0035] In Fig. Figure 24 shows an installation example in which the coaxial coupling 1 is mounted at the corners of four ceiling elements 93a, 93b, 93c, 93d. For this purpose, the ceiling elements are each milled at one corner with a recess 101 according to Fig. 24a prepared.

[0036] In Fig. Figure 25 shows an installation example in which the coaxial coupling 1 penetrates two ceiling elements 93e and 93f laid parallel along their longitudinal edges. For this purpose, the ceiling elements are each milled with a recess 104 on one edge 103 according to Fig. 24a prepared.

[0037] Fig. Figure 26 shows a support at two corners of ceiling elements 93h and 93i and one edge of ceiling element 93g. The milled recesses prepared for this purpose correspond to those of the Fig. 24a and Fig. 25a.

[0038] Based on the Fig. The individual assembly steps are described below in sections 27 to 36.

[0039] In a first step according to Fig. 27 the lower component 90 is prepared with a milling 89.

[0040] Fig. Figure 28 shows how the lower part of the coaxial coupling 1, comprising the telescopic cylinder 10 with the base plate 20 and the subsequent fastening according to Fig. 29 by means of the screws 99.

[0041] Fig. Figure 30 shows how, after fastening, the pressure plate 50 and the insulating element 60 are placed over the telescopic cylinder 10 and inserted into the milled recess 89.

[0042] The ceiling element 93 is then installed, as shown in Fig. 31 is shown.

[0043] Once the ceiling element is aligned, the centering plate 40 is screwed to the ceiling element 93 using the screws 98, as shown. Fig. 32 is reproduced.

[0044] The Fig. Figure 33 shows how the upper part of the coaxial coupling 1, comprising the piston 11 with the head plate 30 arranged on it, is attached to the upper component 91 by means of the screws 99.

[0045] Fig. 34 shows the insertion of the according to Fig. 33 prepared upper component with upper part of coaxial coupling 1 into the lower part of the coaxial coupling, which protrudes over the ceiling element 93.
