Description

TECHNICAL AREA

[0001] The present invention relates to an anchoring and connecting element for a base frame consisting of frame profiles, with which the base frame rests on a support surface (ground surface) and which, in addition to connecting the parts of the base frame, also enables the leveling of the base frame and the connection of the frame profiles. The base frame is, for example, the base frame of a terrace, a staircase, a lightweight structure, etc., on which another structure rests. Within the scope of the present invention, a lightweight structure includes lightweight buildings such as small houses, summer houses, garden sheds, huts, outbuildings, garages, gazebos, shelters, etc. Within the scope of the present invention, a frame profile includes wooden beams, plastic profiles, composite profiles, metal profiles, and hollow profiles made of plastic, composite material, and metal. STATE OF THE ART

[0002] The solution closest to the present invention is known from European patent EP4276250, which discloses a floor connection element connected to the base frame of a lightweight construction, comprising an angle iron at the upper end and a support disc at the lower end, and a support rod in between, which is connected at the upper end to an angle profile by a threaded connection and rests on the support disc at the lower end with a nut on the rod, so that one end of the support rod protrudes through the support disc.

[0003] This solution is particularly suitable for supporting a wooden base frame on a base surface, but it is not suitable for attaching a wooden base frame, and especially not for attaching a hollow profile base frame made of metal or other materials, nor for connecting the parts of the base frame to each other. This is because, particularly with a hollow profile, the angle profile is only connected to the profile on one side. There is a risk that the fastener (screw, screw-nut connection, rivet) will loosen from the profile under continuously high load.

[0004] Furthermore, the known solution is not suitable for connecting and anchoring the hollow profile sections of the base frame. In particular, the known solutions are not suitable for connecting hollow profiles by locking them at their ends. SUMMARY OF THE INVENTION

[0005] The present invention provides an anchoring and connecting element for a base frame consisting of frame profiles, wherein the anchoring and connecting element enables, in addition to supporting the base frame from below and anchoring the base frame, the connection and holding together of various parts of the base frame.

[0006] The present invention provides a universal anchoring and connecting element for a base frame consisting of frame profiles, which simultaneously serves as a connecting element between the profile sections of the base frame used to anchor the base frame to the support surface, and which enables leveling and alignment of the base frame. The solution provided by the present invention is particularly suitable for a base frame consisting of hollow frame profiles.

[0007] The present invention relates to an anchoring and connecting element for a base frame consisting of frame profiles, comprising a support clamp to be connected to the base frame and a foot to be supported on the ground, as well as a support rod arranged between them and connecting them to each other. The distance between the support clamp and the foot is adjustable in the longitudinal direction of the support rod by changing their relative position by means of a threaded connection.

[0008] The support bracket is designed in such a way that it supports the frame profile of the base frame at least from the underside and encompasses the frame profile of the base frame from at least two opposite sides and connects at least one frame profile of the base frame with at least one other frame profile of the base frame.

[0009] In a preferred embodiment of the support clamp, it is configured such that it connects at least one frame profile of the base frame perpendicularly with at least one other frame profile of the base frame.

[0010] In another embodiment of the support clamp, the support clamp is designed with a U-shaped profile section for end-to-end connection of two successive frame profiles.

[0011] The support clamp includes at least one U-shaped profile section for gripping the frame profile of the base frame.

[0012] The support clamp is connected to the support rod via a threaded connection.

[0013] In another embodiment, the support clamp is connected to the support rod by a welded connection.

[0014] The foot is connected to the support rod via a threaded connection.

[0015] In another embodiment, the foot is connected to the support rod by a threaded connection, so that the threaded end of the support rod protrudes through the foot.

[0016] In another embodiment, the foot is connected to the support rod by a welded connection.

[0017] In another embodiment, the support clamp comprises two U-shaped profile sections connected at an angle of 90 degrees.

[0018] In another embodiment, the support bracket comprises two U-shaped profile sections arranged one behind the other on a single straight line, and a third U-shaped profile section between them at an angle of 90 degrees to the two U-shaped profile sections.

[0019] In another embodiment, the support clamp is essentially T-shaped when viewed from above, wherein the support clamp comprises a U-shaped profile section, between the ends of which an additional U-shaped profile section extends at an angle of 90 degrees from the side of this U-shaped profile section.

[0020] Such a configuration is provided for the simultaneous support of the base frame and the connection of the profile sections of the base frame in the base frame in the position where one end of a profile section of the base frame is perpendicular to another profile section of the base frame and these profile sections of the base frame must be connected.

[0021] In another embodiment, the support bracket, viewed from above, is essentially X-shaped, comprising a U-shaped profile section between the ends of which additional U-shaped profile sections extend from both sides of this U-shaped profile section in opposite directions at an angle of 90 degrees. These additional profile sections are positioned on a straight line.

[0022] Both U-arms of a U-shaped profile section include at least one opening for a fastening element.

[0023] The base is designed as a flat element with a round or polygonal shape in top view, which has an opening for the support rod in a central part of the base.

[0024] The advantage of the present invention is that, in addition to conventional base frames made of frame profiles made of wood and other materials with a solid cross-section, the present invention makes it possible to form the base frame from hollow frame profiles and to connect these profiles together to form a rigid base frame.

DESCRIPTION OF THE EXECUTION FORMS

[0026] For the sake of clarity, identical details and elements in different figures are marked with the same reference symbols.

[0027] Possible embodiments of the anchoring and connecting element of the invention for a base frame 1 made of frame profiles are described in the Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24 to Fig. Figure 25 is shown schematically. In all embodiments shown, the anchoring and connecting element comprises a support bracket 2a, 2b, 2c, 2d, or 2e connected to the base frame 1 and a foot 3 resting on the ground surface. A connecting support rod 4 is arranged between the support bracket 2a, 2b, 2c, 2d, or 2e and the foot 3, the distance between the support bracket 2 and the foot 3 being adjustable in the longitudinal direction of the support rod 4 by changing their relative positions by means of a screw connection. The threaded connection is located at the end of the support rod 4 facing the support bracket 2a, 2b, 2c, 2d, or 2e, at the end of the support rod 4 facing the foot 3, or at both ends.

[0028] At the end facing the support clamp 2a, 2b, 2c, 2d or 2e, the threaded connection includes at least one support nut 7, and the position of the support clamp is fixed by means of a lock nut 9.

[0029] The support nut 7 can be permanently connected to the support clamp 2a, 2b, 2c, 2d or 2e, e.g. by a welded connection, or in other ways, e.g. by using a press nut as a support nut.

[0030] In the illustrated embodiment, the support rod 4 with the support nut 8 rests on the foot 3, with the end of the support rod 4 protruding through the opening 11 in the foot 3. This end of the support rod 4 is pressed into the ground.

[0031] The Fig. 12 and Fig. Figure 13 shows a possible embodiment of the foot 3, which in this case is a disk with an opening 11. Fig. Figure 12 shows an axonometric exploded view of the foot 3, the support rod 4, the support nut 7, and the lock nut 9, which are provided for adjusting and securing the anchoring and connecting element of the invention. In the Fig. In the embodiment shown in Figure 13, the foot support nut 8 is welded to the foot 3.

[0032] It is obvious to a person skilled in the art that the foot 3 can have any other shape, for example, a rectangular (rectangle, square) or polygonal shape. The foot 3 can also have a protrusion (e.g., a cone) at the point where the end of the support rod 4 protruding from the nut 8 rests – this is intended for feet standing on hard ground where the end of the support rod 4 cannot be pressed into the ground.

[0033] The Fig. 1, Fig. 2 to Fig. Figure 3 shows the first embodiment of the L-shaped support bracket 2a, which comprises two U-shaped profile sections 13 rotated 90 degrees relative to each other and connected at one edge of the U-shaped profile sections 13. A support nut 7 is arranged between the mutually curved arms of the U-shaped profile sections and is welded to the support bracket 2a. The U-shaped profile sections 13 are configured to engage the frame profiles 5 and 6 of the base frame 1.

[0034] The Fig. 26 and Fig. Figures 27 show the fastening of the support clamp 2a to the support rod by means of a threaded connection with a support nut 8 and a lock nut 9, as well as by means of a welded connection, wherein the support clamp 2a is connected to the support rod by means of the welded connections 12.

[0035] In the embodiment shown, the openings for fastening elements such as screws, bolts and rivets in the U-shaped profile sections 13 are not shown, since in the accompanying figures the frame profiles 5 and 6 of the base frame 1 are fastened from below in the encompassing profile sections 13 with self-tapping screws.

[0036] It is obvious to a person skilled in the art that in other embodiments not shown in the figures, the arms of the U-shaped profile sections have openings for the fastening elements.

[0037] Fig. Figure 4 shows the second embodiment of the L-shaped support clamp 2b, which also comprises two U-shaped profile sections 13 rotated 90 degrees to each other and connected to each other by the material section that connects the bottoms of the U-shaped profile sections 13, on one edge of which an opening 10 is arranged.

[0038] In the Fig. 4 and Fig. In the embodiment shown in Figure 28, the support nut 7 is not rigidly connected to the support clamp 2b. The support clamp 2b rests on the support nut 7, and after adjusting the length of the anchoring and connecting element suitable for the foot 3 with the support nut 7 or the support nut 8, the support clamp 2b is fixed between the support nut 7 and the lock nut 9.

[0039] In the Fig. In the embodiment shown in Figure 29, the support nut 7 is rigidly connected to the support clamp 2b by means of a welded connection or, for example, by using a press nut as the support nut 7.

[0040] In this embodiment, the position of the support rod 4 in relation to the support clamp 2b is fixed by turning the lock nut against the support nut 7.

[0041] In the Fig. In the embodiment shown in Figure 30, the support rod 4 is welded directly to the support clamp 2b, and the height of the support clamp 2b in relation to the foot 3 is adjusted only by means of the support nut 8 on the foot 3 - see Figure 30. Fig. 12.

[0042] The Fig. 6 and Fig. Figure 7 shows an embodiment of a T-shaped support clamp 2c. In this embodiment, the support clamp 2c is essentially T-shaped when viewed from above ( Fig. 7), wherein the support bracket 2c comprises a U-shaped profile section 13, between the ends of which an additional U-shaped profile section 13 extends at a 90-degree angle from the side of this U-shaped profile section. The support nut 7 is welded at a 90-degree angle between said profile sections.

[0043] In the Fig. 8 and Fig. 9 The support bracket 2d, viewed from above, is essentially X-shaped, comprising a U-shaped profile section 13, between the ends of which additional U-shaped profile sections 13 extend from both sides of this U-shaped profile section in opposite directions at an angle of 90 degrees. The support nut 7 is welded at a 90-degree angle between the aforementioned profile sections.

[0044] The following examples show the use of the support clamp 2a-2e of the anchoring and connecting element of the present invention for holding and connecting the frame profiles 5, 6 of the base frame 1 consisting of hollow profiles, wherein one of many possible examples for the base frame is shown in the Fig. 14 and Fig. 15 is shown.

[0045] The Fig. 16 and Fig. Figure 17 shows the connection and retention of the frame profile 5 of the base frame 1 and the transversely arranged frame profile 6 with the L-shaped support bracket 2a of the first embodiment on the anchoring and connecting element. The frame profiles 5 and 6 are inserted into the U-shaped profile sections 13 of the support bracket 2a, and the frame profile 6 is fastened and connected by means of self-tapping screws in the illustrated embodiment. The L-shaped support bracket 2a makes it possible to connect the frame profiles 5 and 6 both in the middle part and at the corners of the base frame 1.

[0046] The height of the support bracket 2a in relation to the foot 3 is adjusted by turning the support rod 4 in relation to the support nuts 7 and 8, and the position of the support rod 4 and thus also of the support bracket 2a is fixed by means of the lock nut 9, which is tightened against the support nut 7.

[0047] The Fig. 18 and Fig. Figure 19 shows the connection and support of the frame profiles 5 and 6 of the base frame 1 with the L-shaped support bracket 2b of the second embodiment on the anchoring and connecting element. The main difference of the embodiment of Fig. 14 and Fig. 15 concerns the fastening of the support clamp 2b to the support rod 4, which is referred to above in reference to the Fig. 4 and Fig. 28 is described.

[0048] The height of the support bracket 2b in relation to the foot 3 is adjusted by turning the support rod 4 in relation to the support nuts 7 and 8, and the position of the support rod 4 and thus also of the support bracket 2b is fixed by means of the lock nut 9, which is tightened between the support nut 7 and the lock nut 9.

[0049] The Fig. 20 and Fig. Figure 21 shows the connection and support of two frame profiles 5 and 6 of the base frame 1 with the T-shaped support clamp 2c of the third embodiment on the anchoring and connecting element.

[0050] The T-shaped support bracket 2c is primarily designed to connect the frame profiles 6 located between the ends of the base frame 1 to the frame profile 5. As can be seen from the figures, the support bracket 2c supports two abutting frame profiles 5, which are connected to the support bracket 2c. Otherwise, the fastening and height adjustment of the support bracket 2c is similar to that of the support bracket 2a described above.

[0051] The Fig. 22 and Fig. Figure 23 shows the connection of two frame profiles 5 of the base frame 1 with two frame profiles 6 and the mounting with an X-shaped support bracket 2d according to the fourth embodiment on the anchoring and connecting element. The frame profiles 5 are first placed with their ends onto the support bracket 2d, and then the frame profiles 6 are arranged and fastened with their ends to the frame profile 5.

[0052] Otherwise, the attachment of the frame profiles, the attachment of the support clamp 2d to the support rod 4 and the adjustment of its height are carried out in a similar manner to the support clamps 2a and 2c described above.

[0053] In all embodiments described above, the support clamp 2a-2e is configured to support the frame profile 5 of the base frame 1 at least from the underside and to surround the frame profile 5 of the base frame 1 with the U-shaped profile section from at least two opposite sides and to connect at least one frame profile 5 of the base frame 1 perpendicularly with at least one other frame profile 6 of the base frame 1.

[0054] This aspect makes it possible to use the anchoring and connecting element of the invention simultaneously for the mutual connection of the frame profiles 5 and 6 of the base frame 1 and for anchoring the base frame 1 to the ground. The anchoring and connecting element of the invention also makes it possible to level and straighten the base frame.

[0055] Since the hollow frame profiles 5 and 6 of the base frame 1 are fastened in the area of ​​the U-shaped profile sections of the support brackets 2a-2e, the reliability of the fastening is increased because the U-shaped profile sections prevent the frame profiles 5, 6 from twisting under load about their longitudinal axis and thus prevent the fastening elements (screws, bolts, rivets) from being pulled out of the wall of the hollow profile. The solution of the invention also enables the connection and linking of abutting frame profiles.

[0056] The Fig. 24 and Fig. Figure 25 shows the connection and support of two frame profiles 6 of the base frame 1 with a straight support clamp 2e on the anchoring and connecting element, wherein the ends of the two frame profiles 6 abut each other between the U-shaped profile section 13 of the support clamp 2e and are fastened with screws.

[0057] In all the above-described embodiments of the support clamps, the U-shaped profile sections 13 enable the connection and fastening of the hollow frame profiles 5, 6. Since the frame profiles 5, 6 are clamped to the U-shaped profile sections 13 on both opposite sides, the frame profiles 5, 6 cannot rotate within the U-shaped profile section. Furthermore, due to this configuration, the abutting frame profiles within the U-shaped profile section 13 of the support clamp cannot bend or twist relative to each other.

[0058] Furthermore, the hollow frame profiles 5, 6 can be more easily fastened in the U-shaped profile section 13, since a fastening element (e.g. a screw) can be inserted through the arm of the U-shaped profile section and the abutting wall parts of the hollow profile on opposite sides of the hollow profiles.

[0059] It is obvious to a person skilled in the art that other embodiments are also possible within the scope of the attached claims, which are not described above.
