Construction fence connectors for connecting construction fence elements

Description

[0001] The invention relates to a construction fence connector for connecting a first and second component.

[0002] Construction fences are primarily used for temporary protection or to demarcate or block off construction sites, etc., and are part of the construction site equipment. Standardized galvanized construction fence elements with wire mesh and bases, especially made of concrete, are typically used, allowing for quick and easy installation of construction site barriers.

[0003] Depending on the construction site being set up, different requirements are placed on the construction fence elements. Accordingly, the construction fence elements can be designed to provide dust protection, accident protection, or even include design features. Special requirements apply to construction fences erected near live power lines, especially high-voltage lines. To ensure that the construction fence elements reliably prevent pedestrians from entering and do not topple over, for example, in strong winds, these construction fence elements are usually connected with additional connecting elements in addition to the base feet.

[0004] Construction fence clamps are known from the prior art. These clamps are attached to the vertical parts of the frame sections of the construction fence elements and connect the construction fence elements together in addition to the base feet. These are usually made at least partially of galvanized steel elements.

[0005] However, the use of these construction fence clamps to connect construction fence elements near power lines has the disadvantage that they create a conductive connection between the construction fence elements. Placing construction fence elements near power lines can lead to capacitive coupling of charge into the construction fence elements. While a single construction fence element typically only has a capacitance of approximately 240 picofarads, the electrical connection between the individual construction fence elements created by the construction fence clamps can create a larger total capacitance, which can result in dangerous contact voltages and discharge energies. This endangers people who are near the charged construction fence elements.

[0006] Document GB 2 338 770 A discloses a construction fence connector according to the preamble of claim 1.

[0007] It is therefore the object of the present invention to at least partially remedy the aforementioned disadvantages known from the prior art. In particular, the object of the present invention is to provide a construction fence connector for connecting construction fence elements, which increases safety while simultaneously ensuring a simple, cost-effective installation of a construction fence.

[0008] The above object is achieved by a construction fence connector having the features of the main claim. Further features and details of the invention emerge from the respective subclaims, the description, and the drawings.

[0009] According to the invention, a construction fence connector is provided for the (mechanical) connection of a first and a second construction fence element, which are erected in particular near live lines, in particular three-phase overhead lines. This connector has a first and a second clamping element which can be connected to one another and, in a connected state, form at least a first and a second opening through which a frame section of the first and second construction fence element can be guided and / or fixed, thereby connecting the construction fence elements to one another. Furthermore, the invention provides that the clamping elements each have at least one insulator section, wherein the insulator sections are designed such that the construction fence elements are electrically separated from one another (meaning galvanic separation) when the construction fence elements are (mechanically) connected by the clamping elements.In other words, at least two connecting elements (in the form of clamping elements) are provided which, in a connected state, are arranged around frame sections of the construction fence element in order to connect them to one another. The clamping elements are designed in such a way that even if they touch (meaning contact) the construction fence elements, they do not establish an electrical connection between the construction fence elements. This achieves, in particular, galvanic isolation of the respective frame sections and the construction fence elements as a whole. The term “insulator section” refers to any device or element which is suitable for preventing a significant flow of electrical current. A wide variety of arrangements are conceivable, whereby it is crucial that the current path between the two construction fence elements remains interrupted.It can be provided that the clamping elements themselves form the insulator section (at least partially or completely). This reliably prevents the construction fence connector from forming an electrical connection between the connected construction fence elements.

[0010] It can be provided that the insulator section comprises a material which has a high specific resistance and / or a high dielectric strength, at least under naturally occurring outdoor ambient conditions. Such a material can be, for example, a ceramic, in particular an aluminum oxide ceramic, a porcelain, a glass, a plastic, in particular a glass-fiber-reinforced plastic, an epoxy resin, or a combination of these materials. It can be provided that the material has a specific resistance of less than 10 12 < Ω m, preferably less than 10 13 < Ω m, and particularly preferably less than 10 14 < Ω m.The plastic can, for example, be a thermoplastic, in particular acrylonitrile butadiene styrene (ABS), polyamide (PA), polylactate (PLA), polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polystyrene (PS), polyetheretherketone (PEEK) and polyvinyl chloride (PVC), which can be produced cost-effectively.

[0011] Thermoplastics offer the advantage of being moldable within a specific temperature range, making it particularly easy to manufacture the insulator sections in a wide variety of geometries, allowing them to be adapted to the frame sections and simplifying assembly. Furthermore, thermoplastics can generally also be welded, creating a material-to-material bond between or on the clamping elements.

[0012] The use of ABS offers the advantage that it is particularly resistant to weathering and aging. The use of PS offers the advantage that these plastics have particularly high strength and rigidity while being chemically resistant. PA offers the advantage of being particularly UV-resistant, meaning that it can be used outdoors for extended periods, even in direct sunlight. The use of PMMA offers the advantage that it is particularly scratch-resistant and is also resistant to weathering and aging. The use of PC for the insulator section offers the advantage that polycarbonates are characterized by particularly high impact strength, rigidity and hardness, making them mechanically particularly robust while being lightweight. PET offers the advantage of being resistant to many chemicals. PE is a particularly good electrical insulator and has good tracking resistance.PP is similar to PE in its properties and therefore also in its advantages, although PP products are generally particularly inexpensive to produce. PS is also a particularly inexpensive plastic and is also resistant to water exposure. To compensate for PS's sensitivity to UV radiation, the plastic can be treated with an additive that acts as a UV stabilizer. The use of PEEK offers the advantage that its good chemical and mechanical properties are maintained even at high temperatures. PVC offers the advantage of being a good insulator, which reliably prevents an electrical connection from forming between the construction fence elements.

[0013] It may further be provided that a weatherproof section is provided on the clamping elements, which is designed to prevent the deposition of precipitation on the clamping elements. Precipitation can, for example, be rain and / or snow, depending on the weather. Furthermore, it is also conceivable that the deposition of other conductive materials on the surface of the clamping elements is prevented.

[0014] For example, the surface of the clamping elements can be designed to have a particularly low surface accuracy so that precipitation cannot settle there. The surface accuracy can also be adjusted so that water enters a Cassie-Baxter state when it comes into contact with the surface, causing larger water droplets to roll off the surface.

[0015] Furthermore, a hydrophobic coating can be provided on the clamping elements, which also prevents water from accumulating on the surface of the clamping elements.

[0016] Alternatively or additionally, the clamping elements can be designed with a geometry that prevents precipitation from accumulating on the clamping elements, particularly when connected, but instead is drawn off by gravitational forces. For example, a chamfer can be provided on at least one edge of the clamping element for this purpose. All of the aforementioned embodiments of the weather section offer the advantage of reliably preventing the flow of leakage current.

[0017] The clamping elements can be designed to be identical. This offers the advantage of lower manufacturing costs and simplifies the installation of the construction fence connectors.

[0018] Furthermore, it can be provided that at least three or more clamping elements can be connected to one another and, in the connected state, form a first and second opening through which a frame section of the first and second construction fence elements can be guided, thereby connecting the construction fence elements to one another. This offers the advantage that the clamping elements can be easily adapted to the geometry of the construction fence elements, thus facilitating installation.

[0019] The clamping elements can be designed to have different geometries. This allows different requirements to be met with different geometric features of the clamping elements. For example, it may be necessary for the clamping elements to be connectable from only one side, for example, to prevent unauthorized access to the connection between the clamping elements.

[0020] The connection between the clamping elements can be positively connected and / or force-fit and / or bonded. A positive connection offers the advantage that it is particularly easy to produce during assembly, which simplifies the installation of the construction fence connectors. For example, the clamping elements can be designed such that they can be plugged together to form a positive connection. This represents a particularly simple installation option. It can also be provided that the clamping elements are designed such that they can be glued together, thereby particularly reliably preventing access by unauthorized persons. It can be provided that the clamping elements are designed to be weldable, in particular plastic-weldable, so that a bonded connection can be produced. This also particularly reliably prevents access by unauthorized persons.

[0021] It is further conceivable in the construction fence connector according to the invention for the clamping elements to comprise at least partially or completely an electrically insulating material. In other words, the clamping elements can be made substantially from an electrically insulating material, so that they reliably prevent current flow even when voltage is applied to the clamping elements. Furthermore, this prevents charge separation within the clamping elements due to induction, which could also lead to electrical flashovers. It can also be provided that the entire construction fence connector consists substantially, in particular exclusively, of an insulating material, in particular a plastic. This particularly reliably prevents an electrical connection from being established between the construction fence elements when the clamping elements are connected to one another.

[0022] Furthermore, in a construction fence connector according to the invention, it can advantageously be provided that the electrically insulating material of the clamping elements is produced as a single-component or multi-component injection-molded part, wherein preferably at least one thermoplastic material is present. Production as a single-component injection-molded part offers the advantage that the clamping elements can be manufactured particularly easily and cost-effectively. With a two-component or multi-component injection-molded part as the clamping element, the advantage is achieved that different properties can be achieved at different positions in the clamping element by using different materials. For example, it can be provided to produce the insulator section from a different material than the rest of the clamping element.This can, for example, provide the advantage of maintaining the electrical insulation properties in the insulator section, while allowing a more cost-effective or easier-to-process material to be used for the remaining part of the clamping element. In particular, plastics, such as those described in connection with the insulator sections, can be used for the clamping elements.

[0023] Furthermore, in the construction fence connector according to the invention, it is conceivable for the clamping elements to comprise a UV-resistant material, in particular a plastic with at least one sterically hindered amine as an additive light stabilizer. The use of a UV-resistant material offers the advantage that the clamping elements can also be used outdoors for extended periods of time without, for example, reducing the mechanical stability of the clamping elements. In the case of plastics in particular, UV radiation can lead to a deterioration in the mechanical properties over time. By adding so-called hindered amine light stabilizers (HALS), i.e. sterically hindered amines, to the clamping elements, the negative influence of UV rays on the material can be reduced. It is also conceivable for the clamping elements to be protected against external environmental influences by a coating, such as a layer of lacquer or chrome.

[0024] Furthermore, in the construction fence connector according to the invention, it can advantageously be provided that the insulating material of the clamping elements has, in particular, mechanical, reinforcing means, in particular in the form of fibers, which preferably comprise glass fibers and / or carbon fibers. In other words, it can be provided that the clamping elements have at least one mechanical reinforcing element designed to improve the mechanical properties of the clamping elements, in particular the hardness, impact resistance, and / or strength. This offers the advantage that even a material that is fundamentally unsuitable due to its inherent mechanical material properties, but which nevertheless has other advantages, is nevertheless suitable for use as a clamping element.Furthermore, in the construction fence connector according to the invention, it is conceivable that the clamping elements each have at least two recesses which form the openings when connected. In other words, the geometry of the clamping elements can be adapted to the construction fence elements in such a way that, when the clamping elements are connected, they can be passed through the connected clamping elements. This offers the advantage that the clamping elements are particularly easy to assemble and the construction fence elements are particularly easy to connect to one another. The openings formed by the recesses can have different shapes, in particular a circular shape, a semicircular shape, an elliptical shape or an elongated hole shape. The circular shape offers the advantage that it fits particularly well with the generally circular cross-section of the frame sections of the construction fence elements, thus enabling a particularly stable connection of the construction fence elements.The slotted hole shape offers the advantage that, on the one hand, a good mechanical connection of the construction fence elements is possible at the end points, whereby the position of the frame sections of the construction fence elements and thus of the construction fence elements as a whole can be changed within the slotted hole without the connection of the construction fence connector having to be separated.

[0025] Preferably, the construction fence connector according to the invention can be provided with openings dimensioned such that some clearance remains between the openings and the frame sections. This offers the advantage that the construction fence elements can still be moved even when connected, and that the development of mechanical stresses between the construction fence elements and clamping elements, or between the construction fence elements themselves, is avoided. Furthermore, the risk of creating an electrical current path between the construction fence elements is further reduced.

[0026] In the construction fence connector according to the invention isIt is provided that the clamping elements at least partially or completely have a honeycomb structure, wherein preferably a surface of the clamping elements in the region of the openings is designed to be closed. This offers the advantage that the construction fence connector remains stable in the areas provided with the honeycomb structure even with reduced material usage. The term honeycomb structure is understood to mean a cellular structure which has, in particular, hexagonal cavities which can be arranged next to one another without gaps. It can also be provided that the cells have a triangular or quadrangular structure. It can be provided that the honeycomb structure is visible from outside the clamping element, whereby a particularly large amount of material can be saved.Alternatively, it can also be provided that the honeycomb structure is only provided in the interior of the clamping element, in particular not in the surface area of ​​the openings, thereby preventing deposits from accumulating in the clamping elements.

[0027] Preferably, in the construction fence connector according to the invention, the clamping elements can be provided with at least one guide opening, in particular a through-opening, which is arranged in particular orthogonally to the first and second openings, through which a connector can be guided in order to connect the two clamping elements to one another. This offers the advantage that the clamping elements are particularly easy to connect to one another. It can be provided that the guide opening has a thread into which a connector can engage. This offers the advantage that a particularly secure connection can be ensured.

[0028] Furthermore, in the construction fence connector according to the invention, it can advantageously be provided that the guide opening is arranged between the first and second openings. This prevents the frame sections of the construction fence elements from being located in the area through which the connector is guided to connect the clamping elements during assembly of the construction fence connector.

[0029] Furthermore, in the construction fence connector according to the invention, it is conceivable that the geometry of the guide opening is suitable for receiving a nut, in particular in a form-fitting manner, in particular that the diameter is between 10 mm and 24 mm, preferably between 13 mm and 18 mm. This has the advantage that rotation of the clamping elements with respect to the nut is prevented, thereby simplifying assembly. It can be provided that the nut is designed as a metric nut, in particular an M10 nut. Furthermore, it can be provided that the nut is injection-molded into the clamping element. This offers the advantage that the nut is protected from external influences. Furthermore, it can be provided that the nut is designed as a self-locking nut in order to prevent it from becoming loose.

[0030] Furthermore, in the construction fence connector according to the invention, it can be provided that the guide opening has a stepped bore. A stepped bore offers the advantage, for example, that a screw with a head can rest on the step of the bore, wherein the movement of the screw is limited when connecting the clamping elements, thereby simplifying assembly. It can also be provided that at least one guide opening is designed as a blind hole. This offers the advantage that an end stop is formed for the connector, by which the movement of the connector is limited, thereby simplifying the assembly of the construction fence connector. Furthermore, the penetration of deposits into the guide opening from this side is prevented.

[0031] Furthermore, in a construction fence connector according to the invention, it is conceivable that the distance between the first and second openings is between 70 mm and 30 mm, and preferably between 60 mm and 50 mm, and / or the distance between the centers of the openings is between 80 mm and 120 mm, and preferably between 90 mm and 110 mm, and / or the length of a longitudinal side of the clamping elements is between 120 mm and 160 mm, and preferably between 130 mm and 150 mm. This offers the advantage that the construction fence connector can be particularly easily attached to standardized construction fence elements.

[0032] It can further be provided in the construction fence connector according to the invention that at least one of the clamping elements has a connector which is guided through at least one guide opening of the clamping elements when the clamping elements are connected, as well as a securing element which can be connected to the connector when the connector is guided through the guide opening. It can be provided that the connector is designed as a threaded rod. This offers the advantage that the connector can be connected to the clamping element particularly easily, in particular if the clamping element has a mating thread. It can also be provided that the connector is designed as a screw. Alternatively, it can also be provided that a connector designed as a threaded rod has a handle or wing, whereby the connector can also be connected to the clamping elements without tools.Alternatively or additionally, it can also be provided that the connector is firmly connected to at least one clamping element, for example in a form-fitting and / or material-fitting manner, in particular by injection-molding. This offers the advantage that assembly is simplified in that the connector cannot be lost when connecting the clamping elements. It can be provided that the connector comprises a plastic or is made essentially thereof, whereby the electrical conductivity is reduced and the safety of the construction fence connector is increased. It can be provided that the clamping elements, the connector and the securing element form a connector system, wherein the entire connector system can comprise a plastic or be made essentially of plastic, whereby an electrical connection between the construction fence elements is avoided and the safety of the construction fence connector system is increased.Furthermore, in the construction fence connector according to the invention, it is conceivable for the securing element to be designed as a nut, in particular as a safety nut (meaning self-locking). This offers the advantage that, on the one hand, simple assembly is ensured and, on the other hand, the nut is prevented from coming loose. It can also be provided that the nut is designed as a wing screw in order to enable tool-free assembly. Furthermore, it can be provided that the nut is designed such that it can only be connected to the connector using a special tool, for example a hexagon socket connection, Torx ®<, which can in particular prevent unauthorized disassembly. Alternatively, a bayonet lock can also be provided, which enables quick and easy assembly and disassembly.

[0033] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. They show schematically: Fig. 1 shows a construction fence connector according to the invention in connection with a first and second construction fence element, Fig. 2 shows a perspective view of a construction fence connector according to the invention in a connected state, Fig. 3 shows a plan view of a clamping element according to the invention, Fig. 4 shows a further plan view of a clamping element according to the invention, Fig. 5 shows a side view of a construction fence connector according to the invention in the connected state, and Fig. 6 shows a further plan view of clamping elements according to the invention with a connector in a separated state

[0034] In the following description of some embodiments of the invention, the same reference numerals are used for the same technical features even in different embodiments.

[0035] Figure 1 shows a construction fence connector 10 according to the invention, which connects a first construction fence element 200 and a second construction fence element 300 at a frame section 210 of the first construction fence element 200 and at a frame section 310 of the second construction fence element 300. As in the Figure 1 As shown, the construction fence elements 200, 300 can also be supported by a base connector 400. Construction fence elements 200, 300 can have both frame sections 210, 310 and a region located within the frame sections 210, 310, which can be designed as a grid.

[0036] Figure 2 shows a construction fence connector 10, which has a first clamping element 11 and a second clamping element 12. In the Figure 2the clamping elements 11, 12 are shown in a connected state II, whereby they form a first opening 13 and a second opening 14, through which a frame section 210, 310 of the first and second construction fence element 200, 300 can be guided. According to the Figure 2 The connected clamping elements 11, 12 can form a cuboid-shaped body. It can be provided that at least one of the clamping elements 11, 12 has a connector 19, which is guided through at least one guide opening 18 of the clamping elements 11, 12 when the clamping elements 11, 12 are connected.

[0037] It can be provided that the clamping elements 11, 12 at least partially or completely comprise an electrically insulating material. It can also be provided that the electrically insulating material of the clamping elements 11, 12 is manufactured as a single-component or multi-component injection-molded part, preferably a thermoplastic material.

[0038] It can also be provided that the clamping elements 11, 12 comprise a UV-resistant material, in particular a plastic with at least one sterically hindered amine as an additive light stabilizer. It is also conceivable that the electrically insulating material of the clamping elements 11, 12 comprises, in particular, mechanical reinforcement means, in particular in the form of fibers, which preferably comprise glass fibers and / or carbon fibers.

[0039] It can also be provided that the guide opening 18 is arranged between the first and second openings 13, 14. In the Figure 2 It is indicated that the clamping element 12 at least partially has a honeycomb structure 17, wherein an inner surface 26 of the clamping element 12 is designed to be closed in the region of the openings 13, 14. The connector 19 is in the Figure 2 secured by a securing element 20.

[0040] The clamping elements 11, 12, the connector 19 and the securing element 20 can form a construction fence connector system 100, which offers the same advantages as the construction fence connector 10.

[0041] The Figure 3 shows a clamping element 11, 12 with an insulator section 15, 16 formed between recessed areas 21 of the clamping element 11, 12. The recesses 21 can form the openings 13, 14 in the connected state II. The insulator section 15, 16 prevents a current from flowing between the construction fence elements 200, 300 when the construction fence elements 200, 300 are connected to one another by the construction fence connector 10.

[0042] In addition, the Figure 3a distance L1 between the first and second openings 13, 14, which can be between 70 mm and 30 mm and preferably between 60 mm and 50 mm. Also shown is a distance L2 between the centers of the openings 13, 14, which can be between 80 mm and 120 mm and preferably between 90 mm and 110 mm. Figure 3 shown is a length L3 of a longitudinal side of the clamping elements 11, 12, which can be between 120 mm and 160 mm and preferably between 130 mm and 150 mm.

[0043] An alternative design of the insulator section 15,16 is shown in the Figure 4 shown. The insulator section 15, 16 can extend over the longitudinal side of the clamping element 11, 12 and at a contact surface 24, which meets a corresponding contact surface 24 of the clamping element 11, 12 when the clamping elements 11, 12 are connected to one another, and an inner surface 26 of the recess region 21.

[0044] Also in the Figure 4Shown is a honeycomb structure 17 provided in the clamping element 11, 12, which is visible from above in a broken portion of the transverse surface 23. It can be provided that the surface of the clamping elements 11, 12 is designed to be closed in the region of the openings.

[0045] The Figure 5 shows the construction fence connector 10 in a connected state II from the side. It can be seen how the first clamping element 11 with a contact surface 24 meets the second clamping element 12 and its contact surface 24. A frame section 210, 310 of the construction fence element 200, 300 is guided through the first and second openings 13, 14. The openings 13, 14 can be dimensioned such that there is still play between the openings 13, 14 and the frame sections 210, 310. Also in the Figure 5It is shown that the longitudinal surface 22 can be connected to the transverse surface 23 via a bevel 27. This offers the advantage that precipitation cannot accumulate on the transverse surface 23. Alternatively, at least one weather section 27 can be provided, which can also be designed as a water-repellent coating or structured surface.

[0046] The Figure 6 shows a construction fence connector 10 according to the invention or a construction fence connector system 100 with clamping elements 11, 12. The clamping element 11 is connected to the clamping element 12 by a connector 19, which is guided through a guide opening 18.

[0047] The through opening 18 is in accordance with the Figure 6orthogonal to the first and second openings 13, 14. The connector 19 can be designed, for example, as a threaded rod or screw or as a threaded rod with a handle. The guide opening 18 can have a thread that can be brought into operative connection with a corresponding mating thread of the connector 19. As shown in the Figure 6 As shown, the guide opening 18 can be designed both as a through opening 18 as shown in the second clamping element 12 and as a stepped bore 25 as shown on the first clamping element 11.

[0048] Furthermore, it can be provided that the geometry of the guide opening 18 is suitable for receiving a nut, in particular in a form-fitting manner, in particular that the diameter is between 10 mm and 24 mm, preferably between 13 mm and 18 mm. When connecting the clamping elements 11, 12 to the connector 19, the contact surfaces 24 of the clamping elements 11, 12 meet, forming a first opening 13 and a second opening 14 through which the frame sections 210, 310 of the construction fence elements 200, 300 can be guided, whereby the construction fence elements 200, 300 can be connected. The above explanation of the embodiments describes the present invention exclusively within the scope of examples. List of reference symbols
