Description
[0001] The invention relates to a barrier element, in particular a construction fence.
[0002] Such barrier elements are used, for example, on construction sites to secure areas from the surrounding area, preventing unauthorized access, or to separate and direct pedestrian traffic. Requirements for such barrier elements include low weight, easy assembly and disassembly without heavy equipment, easy transport, and sufficient stability against weather influences such as wind or mechanical impacts on construction sites, e.g., accidental collisions with construction equipment.
[0003] A variety of such barrier elements are known from the prior art, typically consisting of a grid element and a tubular frame. Also known are various elements for securing such barrier elements to one another, as well as elements for ensuring secure support, such as support feet and the like.
[0004] DE 10 2009 037 977 A1 discloses a barrier element of increased stability with a tubular frame formed from tubular elements configured as square profiles and a separating element, such as a grid element, arranged between the tubular elements. Individual or all tubular elements have a groove-like receptacle along their longitudinal extent for securely holding and positioning the separating element. The cross-section of the tubular elements has a groove-like recess for accommodating the grid elements. Such barrier elements are complex to manufacture.
[0005] DE 20 2007 006 279 U1 discloses a fence module with a frame and a mesh arranged therein. The frame consists of a base, a top, and two side struts, each designed as square tubes. The mesh is attached on all sides to angle elements, which are attached to the frame struts by means of screw connections.
[0006] DE 10 2009 054 411 A1 shows a barrier element with a frame made of tubular elements in the form of profile tubes running around the outer edges, each of which has a step-like receptacle in which the edge areas of the grid element come to rest.
[0007] DE 39 20 108 C1 discloses a fence with vertical posts and lattice panels, wherein the lattice panels are held between rod-shaped holding elements and the posts and are connected by means of several connecting means.
[0008] DE 26 04 136 A1 shows a fence element made of horizontally running longitudinal bars and vertically running cross bars, which is enclosed at least on the vertical sides by a frame made of flat iron bars.
[0009] DE 600 36 046 T2 discloses a protective cover consisting of posts and sections, each section being attached to two posts and comprising at least two struts and a piece of shielding material. The struts are attached to the posts by means of fastening elements.
[0010] DE 1 684 647 A1 shows a fence consisting of posts, horizontally extending bars between the posts and slats extending between the bars and attached to the bars.
[0011] US 8,777,186 B2 discloses a barrier element with vertical and horizontal pipe elements forming a pipe frame and a grid element. The horizontal elements can have sleeves at their ends with which the horizontal pipe elements are inserted into the vertical pipe elements and clamped therein.
[0012] US 6,176,471 B1 describes a fence system consisting of two vertical posts and two horizontal elements, each made of polymer, and a wire mesh element. The horizontal elements are inserted into slots in the posts and thus secured against rotation.
[0013] US 10 570 640 B2 discloses a fence with two vertical posts, two horizontal elements, and a mesh element. The two horizontal elements are inserted through slots in the vertical posts with sealing sleeves.
[0014] US 10 954 690 B1 shows a fence with vertical and horizontal pipe elements, wherein the horizontal pipe elements are passed through openings in the vertical pipe elements in a torsion-proof manner.
[0015] The task is therefore to provide a shut-off element which has increased stability and overcomes the disadvantages of the state of the art.
[0016] According to the invention, the object is achieved by a shut-off element having the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims.
[0017] According to the invention, a barrier element, in particular a construction fence, comprises at least one tubular frame formed from two horizontal and two vertical tubular elements, and a grid element connected to the tubular frame. Furthermore, according to the invention, the horizontal tubular elements are each guided through two opposite openings in the vertical tubular elements on both sides, and the vertical and horizontal tubular elements are arranged in a manner that prevents rotation relative to one another.
[0018] Advantageously, such a barrier element offers increased stability against weather influences, such as wind, especially when privacy screens, construction fence nets, construction site signs, or advertising signs are attached to the barrier element, as well as against unintentional mechanical forces, e.g., from construction vehicles. Another advantage of such a barrier element is its ease of manufacture, allowing it to be assembled by the end user without any special skills. This significantly reduces the transport costs of such barrier elements.
[0019] A horizontal pipe element refers to a pipe element of the shut-off element that is oriented in a horizontal direction. A horizontal direction runs along the surface on which the shut-off element is positioned or arranged during its intended use. A vertical pipe element refers to a pipe element that is oriented at a 90° angle to the horizontal pipe elements and along a vertical direction. A vertical direction runs perpendicular to the horizontal direction and is perpendicular to the surface on which the shut-off element is positioned or arranged during its intended use.
[0020] “On both sides” here means that both ends, or a left and a right end, of each horizontal pipe element are each passed through two opposite openings in the vertical pipe elements. This means that each horizontal pipe element - a first and a second horizontal pipe element - is each passed through both vertical pipe elements, and both horizontal pipe elements are each passed through each vertical pipe element - a first and a second vertical pipe element. The vertical pipe elements therefore each have two opposite openings on both sides, i.e. at their two ends, or at an upper and a lower end, for the horizontal pipe elements to pass through. The upper and lower ends are opposite each other along the longitudinal axis of a vertical pipe element.When the shut-off element is used as intended, the lower end is at a shorter distance from the surface on which the shut-off element is arranged or set up than the upper end. The right and left ends lie opposite each other along the longitudinal axis of a horizontal pipe element. Thus, a first horizontal pipe element is passed through the first and second vertical pipe elements on both sides, i.e. with both of its ends, for example through two opposite openings near the lower end of the first and second vertical pipe elements. The second horizontal pipe element is also passed through the first and second vertical pipe elements on both sides, for example through two opposite openings near the upper end of the first and second vertical pipe elements. This forms the pipe frame.
[0021] Two opposing openings in the vertical pipe elements mean two openings of identical dimensions, arranged on the circumference of a vertical pipe element at a defined height, perpendicular to the longitudinal axis of a vertical pipe element. This advantageously enables the horizontal pipe element to pass horizontally through the vertical pipe element, i.e., at an angle of 90° to the longitudinal axis of the vertical pipe element. Furthermore, the two openings are arranged along an imaginary straight line perpendicular to the longitudinal axis of the vertical pipe element and intersecting the longitudinal axis on the circumference of a vertical pipe element.
[0022] According to the invention, a barrier element, in particular a construction fence, comprises at least one tubular frame formed from two horizontal and two vertical tubular elements, and a grid element connected to the tubular frame. According to the invention, the horizontal tubular elements are each guided through two opposing openings in the vertical tubular elements on both sides, whereby the horizontal and vertical tubular elements can be connected at least partially indetachably at contact areas formed between the horizontal and vertical tubular elements.
[0023] In some embodiments, the horizontal and vertical pipe elements have a consistent cross-section across their entire length along the longitudinal axis of the pipe elements. The longitudinal axis of the pipe elements refers to the axis of the pipe elements that corresponds to the direction of their greatest extension.
[0024] In some embodiments, the horizontal and vertical pipe elements are permanently connected to one another. In some embodiments, the horizontal pipe elements have a different cross-section along their longitudinal axis in sections. Advantageously, the horizontal pipe elements have a different cross-section in those sections along their longitudinal axis that pass through the vertical pipe elements. “Different” in the sense of the invention means that the cross-section of the horizontal pipe elements, with regard to shape and dimensions, in sections along the longitudinal axis of the horizontal pipe elements differs from the cross-section of the horizontal pipe elements in the remaining areas along the longitudinal axis, usually a circular cross-section. In some embodiments, the different cross-section of the horizontal pipe elements is achieved by squeezing. For this purpose, a suitable tool can be inserted from above or below.are inserted into the vertical pipe element at the bottom, which encompasses the horizontal pipe element passed through the openings and achieves a different cross-section in sections.
[0025] In embodiments, the horizontal pipe elements are passed through the vertical pipe elements in such a way that they protrude slightly, in the range of 1 mm to 80 mm, beyond the vertical pipe elements. This means that the two ends of each horizontal pipe element protrude beyond the outer surface of the vertical pipe elements. In embodiments, connecting elements for connecting adjacent shut-off elements can be arranged in the ends of the horizontal pipe elements that protrude beyond the outer surface of the vertical pipe elements. Such connecting elements can, for example, be designed as bolts, wherein the bolts are designed such that they can be arranged in the horizontal pipe elements. In further embodiments, the two protruding ends of each horizontal pipe element are closed, for example by inserted plastic pipe caps.
[0026] The vertical and horizontal pipe elements can have any known dimensions; typical dimensions of the vertical and horizontal pipe elements are in the range of 2000 mm to 3500 mm along the longitudinal axis of the pipe elements.
[0027] In some embodiments, the vertical tubular elements have known connecting elements for connecting to other construction fences. Such connecting elements are preferably designed near the upper end of the vertical tubular elements, for example, as hooks or eyelets. In further embodiments, adjacent barrier elements or construction fences can be connected by means of known clamps that enclose the vertical tubular elements of adjacent tubular elements.
[0028] In embodiments, the horizontal and vertical pipe elements are at least partially permanently connected at contact areas that form between the horizontal and vertical pipe elements. These contact areas form when the horizontal pipe elements are passed through the openings in the vertical pipe elements. These contact areas are formed along the openings. At least partially permanently connected means that the horizontal and vertical pipe elements are connected to one another at least partially at the contact areas, for example, by means of spot welds.
[0029] In preferred embodiments, the tubular frame forms a rectangular shape.
[0030] Typical dimensions of the rectangular tubular frame range, for example, from 2000 mm to 3500 mm in width and up to 2500 mm in height, with the width extending along a horizontal direction and the height along a vertical direction. According to the invention, the tubular elements have a circular cross-section. The cross-section is a surface that runs perpendicular to the longitudinal axis of the respective tubular element. According to the invention, the circular openings in the vertical tubular elements each have two bulges along the circumference of the circular opening, located opposite one another along the diameter of the circular opening.According to the invention, the horizontal pipe elements have a circular cross-section along their longitudinal axis in regions which has two bulges along the circumference which are opposite one another along the diameter of the circular cross-section, so that the cross-section of the openings in the vertical pipe elements corresponds to the cross-section in regions of the horizontal pipe elements.
[0031] According to the invention, the vertical and horizontal pipe elements are arranged in a manner that prevents them from twisting against one another.
[0032] In embodiments, the tubular elements have a circular cross-section with a diameter in the range of 30 mm to 60 mm, preferably 40 mm. In embodiments, the diameters of the vertical tubular elements are larger than the diameters of the horizontal tubular elements. In further embodiments, the vertical tubular elements have a diameter in the range of 35 mm to 45 mm and the horizontal tubular elements have a diameter in the range of 25 mm to 33 mm, e.g., the vertical tubular elements have a diameter of 40 mm and the horizontal tubular elements have a diameter of 28 mm. This advantageously enables the intervention of a tool in order to achieve a different cross-section in sections along the longitudinal axis of the horizontal tubular elements that pass through the vertical tubular elements.
[0033] In further embodiments, the tubular elements have a cross-section of any shape, for example a polygonal, preferably a square, cross-section.
[0034] According to the invention, the openings in the vertical pipe elements are circular.
[0035] It is advantageous if the circular openings in the vertical pipe elements correspond to the circular cross-section of the horizontal pipe elements or are congruent in order to enable the horizontal pipe elements to pass through without any problems.
[0036] In embodiments, the circular cross-section of the horizontal tube elements and the circular openings in the vertical tube elements have the same dimensions.
[0037] According to the invention, the openings in the vertical pipe elements are arranged on both sides.
[0038] On both sides means that the vertical pipe elements have two opposite openings near both a lower and an upper end for the passage of the horizontal pipe elements.
[0039] In further embodiments, the vertical tube elements have two opposing openings in the range of 100 mm to 200 mm, preferably 150 mm, from the lower end of the vertical tube element. In further embodiments, the vertical tube elements have two opposing openings in the range of 10 mm to 100 mm, preferably 10 mm to 50 mm, from the upper end of the vertical tube element.
[0040] In preferred embodiments, the grid element is formed from individual bars.
[0041] The individual rods can have any known shape and dimensions. The individual rods are preferably designed as round rods with a significantly smaller diameter than the diameter of the tubular elements. Typically, the individual rods are permanently connected by welding to form a grid element. Typically, a plurality of vertical and horizontal individual rods are each connected at an angle of 90° to form a grid element. The individual rods can also be connected to each other in other ways, for example, at angles other than 90°.
[0042] In preferred embodiments, the grid element is permanently connected to the tubular frame.
[0043] In some embodiments, the grid element is connected to the tubular frame by spot welding. In other embodiments, the grid element is connected to the tubular frame in such a way that it fills the tubular frame.
[0044] In embodiments, a shut-off element according to the invention is produced by providing two horizontal and two vertical pipe elements and a grid element. The vertical pipe elements provided each have two opposite openings on both sides, i.e. at their two ends. In a first step, the horizontal pipe elements are each passed through the two opposite openings in the vertical pipe elements on both sides, i.e. with their two ends, thus forming a pipe frame. In a further step, a permanent connection is formed between the horizontal and vertical pipe elements by squeezing the horizontal pipe elements in the sections along their longitudinal axis that are passed through the vertical pipe elements. For this purpose, a suitable tool can be inserted from above or below.are inserted into the bottom of the vertical tubular element, encompass the horizontal tubular element passing through the openings, and create a different cross-section in sections. This advantageously changes the cross-section of the horizontal tubular elements in sections and fixes the horizontal tubular elements in the vertical tubular elements. In a further step, the grid element is permanently connected to the tubular frame thus formed, for example, by spot welding.
[0045] In further embodiments, a shut-off element according to the invention is produced by providing two horizontal and two vertical pipe elements and a grid element. The vertical pipe elements provided each have two opposite openings on both sides, i.e. at their two ends. In a first step, the horizontal pipe elements are each passed through the two opposite openings in the vertical pipe elements on both sides, i.e. with their two ends, to form a pipe frame. In a further step, a permanent connection is formed between the horizontal and vertical pipe elements by at least partially permanently connecting the horizontal and vertical pipe elements at the contact areas that form between the horizontal and vertical pipe elements. This can be done, for example, by spot welding.In a further step, the grid element is permanently connected to the tubular frame thus formed, for example by spot welding.
[0046] For the realization of the invention, it is also expedient to combine the above-described inventive embodiments, embodiments and features of the claims.
[0047] The invention further includes the use of a barrier element according to the invention as a construction fence.

The pipe elements 2, 3 each have a circular cross-section, wherein the diameter of the vertical pipe elements 3 is 40 mm and the diameter of the horizontal pipe elements 2 is 28 mm. The horizontal 2 and vertical pipe elements 3 are permanently connected to one another, wherein the horizontal pipe elements 2 have a different cross-section along their longitudinal axis in sections 8. Advantageously, the horizontal pipe elements 2 have a different cross-section along their longitudinal axis in the sections 8 that are passed through the vertical pipe elements 3. The cross-section that differs in section 8 differs in terms of shape and dimensions from the circular cross-section of the horizontal pipe elements 2 in the remaining areas along the longitudinal axis.This can be achieved in embodiments by squeezing the horizontal pipe element 2.
