The foundation stone (1) has at least two differently designed receptacles (2, 3, 4) for posts or the like, which run in the vertical direction (28) and open at the upper side (5).At least one receptacle (2, 3, 4) has at least two sections (13, 14; 15, 16; 17, 18), wherein a first section (13, 15, 17) arranged closer to the upper side (5) has a first width (d1, e1, g1, j1) measured in a direction perpendicular to the vertical direction (28), and a second section (14, 16, 18) arranged further away from the upper side (5) has a second width (d2, e2, g2, j2) measured in the same direction. The first width (d1, e1, g1, j1) is at least 2 mm greater than the second width (d2, e2, g2, j2). The first width (d1, e1, g1, j1) is the smallest width of the first section (13, 15, 17) in this direction, and the second width (d2, e2, g2, j2) is the largest width of the second section (14, 16, 18) in this direction. Each section (13, 14; 15, 16; 17, 18) of this receptacle (2, 3, 4) extends over at least 30% of a total height (c) of the foundation stone (1).

Description

[0001] The invention relates to a foundation stone of the type specified in the preamble of claim 1.

[0002] DE 20 2014 007 440 U1 discloses a generic foundation block that features several receptacles with different cross-sectional shapes and sizes. This allows posts of different sizes and / or cross-sectional shapes to be inserted into the foundation block. At their lower end, the receptacles each have a reduced-diameter offset that prevents posts from protruding downward from the foundation block.

[0003] The invention is based on the object of creating a foundation stone of the generic type which, despite its compact design, enables versatile use.

[0004] This problem is solved by a foundation stone having the features of claim 1.

[0005] In order to be able to hold a large number of different post cross-sections and sizes with the foundation stone, the invention provides that at least one receptacle has at least two sections, wherein the width of the first section located closer to the top is at least 2 mm, in particular at least 4 mm, larger than the width of the second section located further away from the top. Each section extends over at least 30% of the total height of the foundation stone.

[0006] The sections of the receptacles do not have to have constant cross-sectional dimensions across the entire height of the receptacles, but can, for example, have a conical shape. In this case, the first width is the smallest width of the first section in the direction under consideration, and the second width is the largest width of the second section in the direction under consideration. Accordingly, the maximum width of the second section in the direction under consideration is at least 2 mm, in particular at least 4 mm, smaller than the minimum width of the first section in this direction.

[0007] Due to the comparatively large vertical extension of the sections, each section of the support can be used to accommodate a post. Each support is therefore suitable for holding at least two posts of different sizes or cross-sectional shapes. This makes it easy to increase the number of posts that can be secured with the foundation block without significantly changing the external dimensions of the foundation block.

[0008] The width of the recording is in particular the length, width or diameter of the recording.

[0009] A foundation stone is a stone designed to be placed in a depression in the ground and permanently embedded there. In particular, the depression in the ground is filled, for example with concrete or earth, after the foundation stone has been inserted and a post or similar item has been inserted and aligned. Reuse of the foundation stone is not intended. In particular, each foundation stone, when installed, is designed to support exactly one post. The recesses not required for this post and the section of the recess not required for this post are permanently filled.

[0010] In particular, it is provided that a transition section is arranged between the first section and the second section, in which at least one wall delimiting the receptacle encloses an angle of 30° to 60° with the vertical direction. In particular, the angle is 40° to 50°. The transition section forms, in particular, an insertion slope along which a post inserted into the receptacle, which is intended for the second section, can slide and thus be easily positioned in the second section. It has also been shown that a sloped wall offers advantages in terms of concrete compaction during the production of the foundation stone compared to a wall with an arcuate cross-section.

[0011] In particular, the height of the first section, measured in the vertical direction, is greater than the height of the second section of the respective receptacle, measured in the vertical direction. A post inserted into the second section is additionally held in place in the area of ​​the first section by material filled there, such as sand, gravel, concrete, or the like. As a result, a lower height of the receptacle is sufficient to hold a post in the second section than in the first section. In particular, each receptacle has exactly two sections for holding posts. In an alternative design, at least one receptacle with three sections for holding posts with different cross-sectional sizes and / or cross-sectional shapes can also be advantageous.

[0012] To ensure good manufacturability of the foundation stone, it is particularly intended that the sections of the receptacles widen vertically from the bottom to the top. In particular, all walls of the sections of the receptacles have a draft angle of at least 5°. In particular, the draft angle is at least 1°. In particular, all sections of the receptacles have a core taper of at least 0.5 mm, in particular of at least 1 mm.

[0013] In particular, the foundation stone has at least three receptacles, particularly advantageously exactly three receptacles for posts or the like. In particular, the central axes of all receptacles lie in a common plane. The centers of the receptacles lie in particular on a straight line on the upper side of the foundation stone. This makes it particularly easy to produce all receptacles with a common core holder. This simplifies the production of the foundation stone. The foundation stone consists in particular of concrete and is produced using a vibro-press process. The foundation stone is in particular pressed from earth-moist concrete. Alternatively, it can be provided, for example, that the foundation stone is produced by casting. In particular, the plane on which the central axes of all receptacles lie runs in the longitudinal direction of the foundation stone.The longitudinal direction runs in particular in the direction of the greatest extent of the foundation stone. In particular, the plane divides the foundation stone into two parts that are mirror-symmetrical to each other.

[0014] In particular, at least one circumferential side of the foundation stone, in particular a longitudinal circumferential side, has a receiving groove. The receiving groove is dimensioned in particular to accommodate a lawn edging stone. A favorable shape for the production of the foundation stone results if the receiving groove extends in a longitudinal section of the foundation stone in which the receptacle with the smallest width measured in the transverse direction of all receptacles is arranged and into which no receptacle with a greater width measured in the transverse direction extends. By arranging the receiving groove in this area, largely uniform wall thicknesses of the foundation stone can be easily achieved.

[0015] In particular, at least one circumferential side of the foundation stone has a bevel in which the circumferential side forms an angle of more than 90° with the top side. The angle is measured in the foundation stone between the top side and the bevel. In the area of ​​the bevel, the circumferential side forms an upward undercut when embedded in the ground. This increases the stability of the foundation stone against tipping and pulling out. In particular, at least two opposing circumferential sides of the foundation stone have a bevel.

[0016] An advantageous design is achieved when at least one receptacle has a circular cross-section and at least one receptacle has a rectangular cross-section. In a particularly advantageous design, a receptacle with a circular cross-section is arranged between two receptacles with rectangular cross-sections.

[0017] The foundation stone is comparatively high relative to its width and length. The total height of the foundation stone is at least 0.5 times the total width. In particular, the total height of the foundation stone is greater than the total width. This allows for sufficiently high mountings for posts or similar structures, ensuring that the posts are securely held in the foundation stone.

[0018] It can be provided that for at least one receptacle, the smallest width or length of the first section and the largest width or length of the second section are the same. The size of this receptacle therefore only changes in one direction from one section to the other. In particular, the width of the receptacle differs in the two sections, while the length – except for any continuous draft angle – remains the same.

[0019] In particular, the foundation stone has a groove on its upper side. The groove runs through all of the foundation stone's recesses. The groove is formed, in particular, by a core holder.

[0020] An embodiment of the invention is explained below with reference to the drawings. They show: Fig. 1 a perspective view of a foundation stone, Fig. 2 a top view of the foundation stone from Fig. 1, Fig. 3 a section along the line III-III in Fig. 2, Fig. 4 a section along the line IV-IV in Fig. 2, Fig. 5 a section along the line VV in Fig. 2.

[0021] Fig. 1 shows a perspective view of a foundation stone 1. The foundation stone 1 is made of concrete. In the exemplary embodiment, the foundation stone 1 has three receptacles 2, 3, and 4. The receptacles 2, 3, and 4 open at an upper side 5 of the foundation stone 1. The receptacles 2, 3, 4 are designed to receive and hold a post or the like. The foundation stone 1 is intended to be inserted into a depression in the ground. The upper side 5 of the foundation stone 1 points upwards. A post or the like can then be inserted and aligned in one of the receptacles 2, 3, or 4. The depression in the ground is then filled with the foundation stone 1 and the post inserted in the foundation stone 1, for example with concrete, earth, sand, gravel, or the like.

[0022] The foundation stone 1 has a longitudinal direction 26, a transverse direction 27 oriented perpendicularly thereto, and a vertical direction 28 extending perpendicularly to the longitudinal direction 26 and the transverse direction 27. In the installed state, the vertical direction 28 runs approximately vertically, and the longitudinal direction 26 and the transverse direction 27 run approximately horizontally.

[0023] The foundation stone 1 has two circumferential longitudinal sides 6 and two circumferential transverse sides 7. The circumferential longitudinal sides 6 run in particular parallel to the longitudinal direction 26.

[0024] The circumferential transverse sides 7 run in particular parallel to the transverse direction 27. In the exemplary embodiment, the two circumferential longitudinal sides 6 each have a receiving groove 10. The receiving grooves 10 are each designed to receive a lawn edging stone 31, as in Fig. 2 is shown with a dashed line for one of the receiving grooves 10. The lawn edging stone 31 can be held with the foundation stone 1 alternatively or in addition to a post or the like inserted into a receptacle 2, 3, or 4.

[0025] How Fig. As shown in Figure 2, the receiving groove 10 has, in particular, a length 1 measured in the longitudinal direction 28 and a depth m measured in the transverse direction 27. In particular, the length 1 is from 3 cm to 7 cm. The depth m is, in particular, from 1 cm to 4 cm. The maximum depth m is measured, in particular, on the underside 8 of the foundation stone 1.

[0026] How Fig. As shown in Figure 1, the two circumferential longitudinal sides 6 each have a continuous bevel 9, which will be described in more detail below. In the exemplary embodiment, the circumferential transverse sides 7 have no bevels.

[0027] A groove 11 extends along the upper side 5, passing through all receptacles 2, 3, and 4. The groove 11 is formed, in particular, by a core holder, which holds cores for producing receptacles 2, 3, and 4 during the manufacture of the foundation stone 1.

[0028] How Fig. As also shown in Figure 1, a chamfer 12 runs circumferentially along the upper side 5. The chamfer 12 is also formed circumferentially on the receptacles 2, 3, and 4. The chamfer 12 results in improved compaction of the concrete during the production of the foundation stone 1.

[0029] Foundation stone 1 is manufactured using the vibro-compact method, specifically from earth-moist concrete. However, another manufacturing method may also be advantageous.

[0030] How Fig. As shown in Figure 2, the receptacle 2 has a rectangular, in particular a square, cross-section. The receptacle 3 has a round cross-section. The receptacle 4 has a rectangular cross-section.

[0031] The images 2, 3, 4 have central axes 32, 33, 34. The central axes 32, 33, 34 run parallel to the vertical direction 28. As Fig. As shown in Figure 2, all center axes 32, 33, and 34 lie in a common plane 30. This allows all three receptacles 2, 3, and 4 to be molded with a common core holder during the production of the foundation stone 1. In the exemplary embodiment, the plane 30 runs in the longitudinal direction 26.

[0032] As in the Fig. As shown in Figures 3 to 5, the receptacle 2 has a first section 13 and a second section 14. The second receptacle 3 has a first section 15 and a second section 16. The receptacle 4 has a first section 17 and a second section 18. The first section 13, 15, 17 of each receptacle 2, 3, 4 is arranged closer to the top side 5 than the second section 14, 16, 18 of the respective receptacle 2, 3, 4.

[0033] The foundation stone 1 has a bottom side 8. In the exemplary embodiment, the receptacles 2, 3 and 4 extend over a total height c of the foundation stone 1 from the bottom side 8 to the top side 5. The first sections 13, 15 and 17 project to the top side 5. The second sections 14, 16 and 18 project to the bottom side 8. The total height c is measured in the vertical direction 28.

[0034] How Fig. 3 also shows, the foundation stone 1 has a total length a measured in the longitudinal direction 26. The total length a is greater than the total height c. As Fig. As shown in Figure 4, the foundation stone has a total width b measured in the transverse direction 27. The total height c of the foundation stone 1 is, in particular, at least 0.5 times the total width b. In particular, the total height c of the foundation stone 1 is greater than the total width b.

[0035] The receptacle 2 has a smallest width e1 measured in the transverse direction 27 in the first section 13 and a largest width e2 measured in the same direction in the second section 14. The second width e2 is at least 2 mm, in particular at least 4 mm, smaller than the first width e1. In particular, the first width e1 is 1.1 times the second width e2.

[0036] Recording 3 has in the first section 15 a Fig. 3 and a largest diameter g2 in the second section 16. In Fig. 2 only the second diameter g2 is shown.

[0037] The receptacle 4 has a smallest width j1 in its first section 17 and a largest width j2 in its second section 18. The width j1 and the width j2 are measured in the transverse direction 27. The widths e1, e2, j1, and j2 are constant, except for a draft angle δ, with which all receptacles 2, 3, and 4 widen toward the upper side 5.

[0038] All sections 13, 14; 15, 16; 17, 18 of receptacles 2, 3, and 4 have a core taper, which is, in particular, 1 mm for each section 13, 14; 15, 16; 17, 18. This results in the draft angle δ of all receptacles. Depending on the height of sections 13, 14; 15, 16; 17, 18, the draft angle δ can vary. The peripheral sides 6 and 7 of the foundation stone 1 also have a taper, which is, in particular, 1 mm.

[0039] The smallest width e1, j1 is the smallest extension of the respective first section 13, 17 in the transverse direction 27 and the largest width e2, j2 is the largest extension of the second section 14, 18 in the transverse direction 27.

[0040] The width j2 is at least 2 mm, in particular at least 4 mm smaller than the width j1. In particular, the width j1 is at least 1.1 times the width j2.

[0041] The diameter g2 is smaller than the width e2 and smaller than the width j2. The diameter g2 is the smallest dimension of a receptacle 2, 3, 4 in the transverse direction 27.

[0042] How Fig. 2 shows, the receptacle 3 extends in a longitudinal section 29 of the foundation stone 1, in which the receiving grooves 10 for lawn edging stones 31 are also arranged. The receiving grooves 10 are arranged entirely in the longitudinal section 29. In the longitudinal section 29, only the receptacle 3 is arranged. The receptacles 2 and 4 do not extend into the longitudinal section 29. The longitudinal section 29 is formed by two perpendicular to the longitudinal direction 26, Fig. 2 levels marked with dashed lines.

[0043] The receptacle 2 has in the first section 13 a smallest length d1 measured in the longitudinal direction 26, as Fig. 3. In the second section 14, the receptacle 2 has a maximum length d2 measured in the longitudinal direction 26. The receptacle 4 has a length i. The lengths d1, d2, and i are constant, except for a draft angle δ, with which all receptacles widen toward the top side 5.

[0044] The first section 13 of the receptacle 2 has a height f1 measured in the vertical direction 28. The second section 14 of the receptacle 2 has a height f2 measured in the vertical direction 28. The first section 15 of the receptacle 3 has a height h1 measured in the vertical direction 28. The second section 16 of the receptacle 3 has a height h2 measured in the vertical direction 28. As Fig. As shown in Figure 5, the first section 17 of the receptacle 4 has a height k1 measured in the vertical direction 28. The second section 18 of the receptacle 4 has a height k2 measured in the vertical direction 28. In the exemplary embodiment, the heights f2, h2, and k2 are equal. The heights f1 and k1 are also equal. The height h1 is slightly greater than the heights f1 and k1.

[0045] A transition section 19 extends between sections 13 and 14. A transition section 20 extends between sections 15 and 16. A transition section 21 extends between sections 17 and 18. In the transition sections 19, 20, 21, the walls of the receptacles 2, 3, 4 are inclined to the central axes 32, 33 and 34 at an angle that is significantly greater than the draft angle δ. The wall of the receptacle 2 forms an angle α with the vertical direction 28 in the transition section 19. In the transition section 20, the wall of the receptacle 3 forms an angle β with the vertical direction 28. In the transition section 21, the walls of the receptacle 4 running in the longitudinal direction 26 form an angle γ with the vertical direction 28. As Fig. 3 shows, the walls of the receptacle 4 running in the transverse direction 27 run approximately parallel to the vertical direction 28 and enclose with it only the draft angle δ.

[0046] How Fig. 5 shows, the first section 17 of the receptacle 4 has a smallest width j1. The second section 18 of the receptacle 4 has a largest width j2. The smallest width e1, j1, the largest width e2, j2, the smallest length d1 and the largest length d2 as well as the smallest diameter g1 and the largest diameter g2 are each measured at the transition section. The smallest width e1, j1 and the largest width e2, j2 or the smallest length d1 and the largest length d2 or the smallest diameter g1 and the largest diameter g2 of two sections 13, 14; 15, 16; 17, 18 of a receptacle 2, 3, 4 differ by at least 2 mm, in particular by at least 4 mm. This allows different post sizes to be accommodated in the sections 3, 14; 15, 16; 17, 18 of a receptacle 2, 3 or 4. The angle α, β, γ facilitates the insertion of posts or the like into the second sections 14, 16, 18.This prevents a post, mast or similar object from getting caught on a ledge between sections 13, 14; 15, 16; 17, 18 and being unable to be moved further.

[0047] How Fig. As shown in Figure 4, the bevel 9 forms an angle ε with the top surface 5, measured in the foundation stone 1. The angle ε is more than 90°. The angle ε can, for example, be between 70° and 85°. QUOTES CONTAINED IN THE DESCRIPTION
