Improved industrial tent

Description

[0001] The invention relates to an industrial tent with a flexible roof membrane. Such industrial tents are also referred to as industrial tent halls or lightweight halls. These structures typically comprise a supporting frame made of metal profiles, particularly lightweight metal profiles, and a flexible roof membrane made of tarpaulin material. These structures can be erected on paved surfaces without special foundations and are usually intended for limited-term use. After use, they can be dismantled and re-erected, relocated, or extended elsewhere. The supporting frame is kept as simple as possible and typically includes a ridge beam, one or more intermediate purlins depending on the building width, eaves purlins, and roof beams that support the purlins and are braced against wall posts. The posts rest on anchor plates, which are secured with ground anchors or dowels depending on the nature of the ground.The opposing eaves are connected with tension bracing, and stiffness is achieved using wind bracing.

[0002] Suitable lightweight metal profiles for the supporting structure are known, for example, from DE 20 2005 005 459 U1. The roof rafters advantageously have grooves for receiving the keder of the roof tarpaulin, so that the roof tarpaulin can be pulled directly into the roof rafters and does not need to be tensioned separately. When the roof tarpaulin is pulled in from eaves to eaves, a watertight roof membrane is immediately available. Such profiles are also known from DE 27 19 490 C2. The improvement of the construction of such industrial tents and lightweight halls is the subject of numerous earlier inventions, e.g. DE 29 28 751 C2 discloses a supporting frame for a tent with special connecting molded parts, DE 80 13 194 U1 inserts for profile bars, DE 83 15 104 U1 a beam-stem connector with a beam insertion profile and DE 20 2011 108 692 U1 a hollow profile and a hall frame made of such a hollow profile.DE 30 27 628 A1 describes a profile with a cross-section that approximately corresponds to an inverted "T", with profile extensions serving to accommodate purlins and specially designed for condensation drainage. DE 79 23 460 U1 describes a similarly designed roof truss. WO 2006 / 047864 A1 shows profile bars in the form of double-T profiles for a tent structure with flanges or bolted angle brackets for attaching the spreaders (purlins). DE 10 2011 083 638 A1 also describes a wall or roof structure for an industrial building with purlins intended for attaching a sheet metal skin or tent tarpaulin. US 2008 / 0115455 A1 proposes a hall or tent structure in which the beams are connected to each other via wall and roof panel elements. The panel elements are part of the supporting structure and should also consist of rigid plastic foam with cladding made of wood or corrugated plastic sheets.

[0003] The industrial tents mentioned at the beginning are used not only for industrial purposes, e.g., as warehouses, but also for many other purposes, such as baggage handling at airports, e.g., during the renovation of a terminal building, in wholesale and retail trade as seasonal sales halls or during the construction of a new sales building, as sales halls in the automotive trade, as helicopter hangars, or as workshop halls. For use in situations with special requirements for the climate control or cooling of the interior of such an industrial tent, it is known to clad the walls with insulating panels. An insulating roof tarpaulin is known from DE 20 2004 001 154 U1.

[0004] For special requirements, specific designs are known, e.g., for sewage sludge drying from DE 10 2011 018 279 A1. With regard to special fire protection, it is also known to equip lightweight industrial buildings with a fixed roof. Trapezoidal sheets (cold roof) or insulated panels (warm roof) are usually used, as are also used in conventional permanent industrial buildings. The high and low ribs of the trapezoidal sheets run from the ridge to the eaves to allow rainwater to run off. However, creating a watertight roof membrane from such panels is considerably more complex than with tarpaulins, due to the fastening and sealing elements and the installation effort. The mobility and adaptability of such a building are significantly limited compared to an industrial tent, and the unfavorable load transfer due to the anisotropic stiffness of the roof membrane must be taken into account in the structural analysis.As a result, the costs for such a hall with a solid roof are considerably higher than for an industrial tent with a tarpaulin as a roof covering.

[0005] The invention is therefore based on the objective of providing an industrial tent that is improved with regard to its economic use. This objective is achieved according to the invention by an industrial tent of the type mentioned at the outset, comprising a supporting frame made of profiled bars, wherein the supporting frame comprises a wall construction and a roof construction, and the roof construction comprises purlins and beams, wherein the beams extend from an eave of the roof to the ridge, wherein the roof covering is furthermore formed by a tarpaulin, a layer of metal panels is arranged below the tarpaulin over at least a part of the roof surface of the industrial tent, and the metal panels are supported on the roof construction by means of brackets arranged on the beams.

[0006] The applicant has determined that, with the inventive design, a conventional industrial tent with a flexible roof membrane can be used simply and cost-effectively even in areas where a rigid roof is required from a fire safety perspective. Surprisingly, the inventive design of an industrial tent meets the requirements for fire safety approval as a building with a rigid roof and combines these requirements with the particular advantages of a conventional industrial tent with a flexible roof membrane. Compared to a conventional lightweight building with a hard roof made of trapezoidal sheets or sandwich panels, the advantages of an industrial tent with a flexible roof membrane are retained, namely reliable watertightness against rainwater, minimal assembly time, reduced requirements for assembly aids such as scaffolding and safety netting, as well as lower transport and foundation costs.The time-consuming process of sealing the roof membrane made of trapezoidal sheets or sandwich panels, particularly in the ridge area, is eliminated, as are additional reinforcement measures for the supporting structure to absorb the unfavorable wind loads transmitted through the trapezoidal sheets or sandwich panels. Furthermore, the flexible roof membrane offers the advantage of lower snow loads in everyday use, as the snow slides off much more easily and dangerous ice buildup is not to be expected. Thanks to this invention, industrial tents can now be used economically, with minimal additional effort, even in locations where compliance with fire safety regulations previously prevented their use.

[0007] A particularly advantageous feature of the industrial tent according to the invention is the possibility of equipping only a portion of the roof surface with metal panels, e.g., the part of the industrial tent located in a setback area. This allows the advantages of better utilization of the installation area, even in a setback area, to be combined with the advantages of a tarpaulin roof, such as the entry of daylight into the industrial tent, and all this at particularly low costs while maintaining the mobility and short setup times of an industrial tent with a flexible roof membrane.

[0008] In a particularly economical embodiment of the invention, the metal panels are arranged between the beams of the roof structure. Since such industrial tents are typically provided with standardized beam spacings, the metal panels can also be provided in standardized lengths adapted to the length of the purlins, thus making them readily available and cost-effective for quickly equipping an industrial tent with a fire-resistant roof. The same standard components used for the wall cladding can be used for this purpose.

[0009] Particularly advantageous is the fact that the metal panels are at least partially formed by trapezoidal sheets, and the trapezoidal sheets are preferably arranged so that the corrugations run approximately parallel to the ridge of the industrial tent. In particular, the trapezoidal sheets are arranged so that their high corrugations overlap the purlins between the beams. This allows the desired part of the roof to be covered easily and quickly with the trapezoidal sheets. The trapezoidal sheets can, for example, be placed on the roof from the outside using the loading crane of a truck. Intermediate support on the purlins is thus achieved without any further work, and the trapezoidal sheets are even secured against slippage by the positive engagement with the purlin if only the ridge-side part of the roof surface is to be covered with the trapezoidal sheets. The invention also makes it possible to achieve condensation protection in the conventional manner by inserting an inner membrane.

[0010] Especially for winter use, it may also be advantageous if the metal panels are at least partially formed by insulating panels, wherein the outer side of the insulating panels facing the tarpaulin forming the roof covering is made of a metal sheet at least 0.5 mm thick.

[0011] Even with conventional PVC-coated roofing membranes, the fire protection requirements regarding the spread of a fire when the roof membrane is ignited from the outside can surprisingly be met if the metal panels are arranged between the purlins and the membrane, in particular if the distance between the top of the metal panels and the bottom of the membrane in the area of ​​the rafters is no more than 50 mm, preferably no more than 25 mm, and most preferably about 10 mm to 15 mm.

[0012] It is particularly cost-effective to manufacture if the brackets are formed by profiles attached to the bars and the brackets extend over a predominant part of the length of a bar.

[0013] The problem is further solved by an industrial tent with a profiled bar for use as a beam of a roof structure, wherein the profiled bar has an upper and a lower narrow side in cross-section, the upper narrow side facing the outside of the roof after installation of the profiled bar and the lower narrow side facing the interior of the industrial tent, and wherein the narrow sides of the profiled bar are connected to each other by side stringers, with brackets for receiving metal panels, in particular trapezoidal sheets, being formed on at least one of the side stringers. According to the invention, the brackets extend over a predominant part of the length of the profiled bar and the brackets preferably comprise profile legs that extend approximately perpendicularly from the side stringer, the profile legs preferably being formed by an angle profile attached to the profiled bar.

[0014] The problem is solved in particular by such an industrial tent with a soft roof skin, comprising a supporting frame made of profiled bars, wherein the supporting frame comprises a wall construction and a roof construction, and the roof construction comprises purlins and beams, wherein the beams run from an eave of the roof to the ridge, wherein furthermore the roof skin is formed by a tarpaulin, with a profiled bar according to the invention as a beam.

[0015] This makes it possible, for example with a standardized stock of rental tents, to easily, cost-effectively, and quickly supply and erect an industrial tent in a version that meets the fire protection requirements for a fixed roof by equipping it as needed with metal panels, in particular trapezoidal sheets or insulated panels. With the industrial tent according to the invention, it is even possible for the first time to retrofit an industrial tent already occupied, for example with stored goods, completely or partially into an industrial tent according to the invention, i.e., to equip it with a fire-resistant, fixed roof, for example, because the fire protection requirements have changed due to changes in use near the erection site of the industrial tent, or because the industrial tent is to be used at the erection site for longer than originally planned.To do this, the roof tarpaulin simply needs to be pulled out of the keder grooves – possibly only partially – and the trapezoidal metal sheets can be placed onto the brackets from the outside, so that the stored goods do not need to be removed from the tent. Once the corresponding part of the roof surface is fitted with the metal sheets, the roof tarpaulin is pulled back in, tensioned, and the industrial tent is once again equipped with a watertight roof and, in addition, with a fire-resistant roof, thus protecting the stored goods from ignition by a potential fire in the vicinity, just like in a permanent warehouse with a solid roof.

[0016] The invention will be explained in more detail below with reference to the accompanying drawings and exemplary embodiments. The drawings show: Fig. 1 a schematically represented support frame for an industrial tent, as known from the prior art; Fig. 2 a schematic cross-sectional view of an industrial tent according to the invention; Fig. 3 an enlarged view of detail A from Fig. 2 in the area of ​​the connection of a beam with a purlin; Fig. 4 an enlarged detail view of detail B from Figure 2 laterally onto a profile bar according to the invention as a bar; Fig. 5 a cross-sectional view of a profile bar according to the invention; Fig. 6 a perspective partial view of an industrial tent according to the invention with a partially cut-out tarpaulin as a roof covering; Fig. 7 an enlarged view of an alternative detail A from Fig. 2a further embodiment of an industrial tent according to the invention with insulating panels as metal sheets; and Fig. 8 a further embodiment of an industrial tent according to the invention with only partial equipment of the roof with metal sheets in a schematic top view.

[0017] In Figure 1Figure 1 shows a schematic representation of a support frame 1 made of profiled bars for an industrial tent, as known from the prior art. The support frame 1 comprises a wall structure 2 and a roof structure 3. The roof structure includes a ridge purlin 4, one or more intermediate purlins 5 depending on the building width, and roof beams 6, which support the purlins 4, 5 and are braced on wall supports 7 of the wall structure 2, with the beams 6 extending from an eave 8 of the roof to the ridge 4. The supports 7 rest on anchor plates 9, which are fixed with ground anchors or dowels depending on the nature of the ground. The opposing eave purlins 8 are connected by tension bracing, and stiffness is achieved by means of wind bracing 21, which, for the sake of clarity, are shown in Figure 1 not shown, however in Figure 8 as can be seen. Depending on the size of the supporting structure 1, intermediate supports 10 may also be provided.

[0018] Suitable lightweight metal profile bars for the supporting structure 1 and in particular the beams 6 are known, for example, from DE 20 2005 005 459 U1. The roof beams 6, shown in cross-section as an example, are shown in [reference to be added]. Figure 5 As shown, the roof tarpaulins advantageously have grooves 11 for receiving the keder 12 of a roof tarpaulin 13, e.g., in the form of a PVC-coated roof tarpaulin, so that the roof tarpaulin 13 can be pulled directly into the roof battens 7 and does not need to be tensioned separately. When the roof tarpaulin 13 is pulled in from eaves 8 to eaves 8, a dense, soft roof covering is immediately available.

[0019] Figure 2 Figure 1 shows a schematic, partial cross-sectional view of an industrial tent according to the invention. The detail labeled A in the area of ​​the connection of a beam 6 with a central purlin 5 is enlarged in Figure 2. Figure 3 The detail labelled B, showing a side view of a profile bar according to the invention as a bar 6, is enlarged in Figure 4 depicted.

[0020] The bar 6 formed by a profile bar according to the invention has in the Figure 5The cross-section shown has an upper and a lower narrow side 14, 15, wherein the upper narrow side 14 faces the outside of the roof after installation of the beam 6 and the lower narrow side 15 faces the interior of the industrial tent. The narrow sides 14, 15 of the beam 6 are connected to each other by side panels 16. Brackets 17 for receiving metal sheets in the form of trapezoidal sheets 18 are formed on at least one of the side panels 16. If the beam 6 is not arranged at the edge of the industrial tent, it is naturally advantageous to provide the brackets 17 on both side panels 16 so that trapezoidal sheets 18 can be inserted on both sides of the beam 6. In the illustrated embodiment of the invention, the brackets 17 are formed by an angle profile or angle profile sections attached to the beam 6. The angle profile can be an equal-leg or an unequal-leg L-shaped angle profile.

[0021] The brackets 17 extend over a predominant part of the length of the beam 6. The brackets 17 are interrupted, in particular in the areas where the purlins 4, 5, 8 are connected to a beam 6, so that the distance between the bracket 17 and the grooves 11 for receiving the keder 12 of a roof tarpaulin 13 can be adapted to the depth of the corrugations of a trapezoidal sheet 18 to be used as a metal panel.

[0022] In the industrial tent according to the invention, a layer of metal sheets in the form of trapezoidal sheets 18 is arranged below the roof tarpaulin 13 over at least a portion of the roof surface of the industrial tent, and these sheets are supported by the roof structure 3. The trapezoidal sheets 18 are arranged between the beams 6 of the roof structure 3, as can be seen in Figure 6as can be seen. Since such industrial tents are usually kept in standardized beam spacings, the trapezoidal sheets 18 can also be kept in standardized lengths adapted to the length of the purlins 5 and are thus available cost-effectively for the short-term equipping of an industrial tent with a fire-resistant roof.

[0023] A particularly advantageous feature of the industrial tent according to the invention is the in Figure 8The option shown allows for the partial roof covering of only a portion of the surface with trapezoidal sheet metal panels (18), for example, the part of the industrial tent located within a fire safety setback area. This combines the advantages of better utilization of the installation area, even within a setback area, with the benefits of a tarpaulin roof, such as allowing daylight to enter the industrial tent, all at a particularly low cost. The mobility and short setup times of an industrial tent with a flexible roof membrane are maintained. Figure 8Figure 24 shows a schematic top view of such a situation from a bird's-eye perspective. The roof tarp 13 is omitted from the illustration to allow a clear view of the metal panels 18 and 22. Line 24 designates a setback area required by building regulations or fire safety regulations. This setback area must be kept clear of buildings without a fixed roof, as defined by regulations concerning roofing resistant to flying sparks and radiant heat, such as those specified in DIN 4102 Part 4. Line 24 could, for example, be a property line or a neighboring building. The boundary of such a setback area is marked here by line 25. As in Figure 8As can be seen particularly well, with an industrial tent according to the invention the available space on a property can be used particularly well and inexpensively for a weatherproof and privacy-protected room at the lowest costs, since only the part of the roof area that lies in the setback area is covered with the metal panels 18, 22 and thus the building law and fire protection requirements can be met.

[0024] With the profiled bar according to the invention as a crossbar 6, such partial fitting of the roof surface with trapezoidal sheets 18 can also be carried out subsequently, for example, if the industrial tent was originally only intended for short-term use and needs to be adapted to the normal building regulations for longer-term use. Compared to the prior art, this eliminates the need to dismantle an industrial tent with a soft roof and erect a new lightweight hall with a solid roof; furthermore, with the profiled bar according to the invention, it is possible to carry out the retrofit without emptying the industrial tent.

[0025] As in Figure 5As shown, an inner tarpaulin 19 can be inserted into grooves 11 on the lower narrow side 15 of a bar 6, so that not only is condensation protection possible in the manner previously customary for industrial tents with soft roof membranes, but also a uniform roof design can still be seen from the interior of the industrial tent.

[0026] The trapezoidal sheets 18 are preferably arranged such that the corrugations run approximately parallel to the ridge of the industrial tent, as shown in Figure 6 This is clearly visible. For clarity, the roof tarpaulin 13 is partially cut away to allow a view of the trapezoidal sheets 18. In particular, the trapezoidal sheets 18 are arranged such that their high ribs 20 overlap the purlins 5 between the rafters 6, see also Figure 3This allows the desired section of the roof to be covered quickly and easily with the trapezoidal sheets 18. The trapezoidal sheets 18 can be installed, for example, from the outside using a truck-mounted crane. Intermediate support on the purlins 5 is thus achieved without any further work, and the trapezoidal sheets 18 are even secured against slippage by the positive engagement with the purlin 5 if only the ridge section of the roof surface is to be covered with the trapezoidal sheets 18.

[0027] In an industrial tent according to the invention, it is also possible to use insulating panels 22 as metal sheets instead of the trapezoidal sheets 18. Such a variant is shown in the alternative illustration of detail A. Figure 2 in Figure 7The insulating panels 22 shown consist of a rigid foam core with a metal sheet facing on both sides. The upper facing consists of a metal sheet, in particular a steel sheet, with a thickness of at least 0.5 mm. Since the insulating panels 22 cannot overlap the purlin 5 like the trapezoidal sheet 18, the purlin is covered in the area of ​​the gap between the adjacent insulating panels 22 with a cover plate 23 between the purlin 5 and the roof membrane 13. The cover plate 23 also preferably consists of a steel sheet with a thickness of at least 0.5 mm. Figure 7 The interruption of the consoles 17 can be seen in the areas where the intermediate purlin 5 is connected to the beam 6.

[0028] The distance between the upper surface of the trapezoidal sheets 18, i.e., the high ribs 20, or the insulating panels 22, and the underside of the membrane 13 is no more than 50 mm in the area of ​​the ribs 6, preferably no more than 25 mm, and particularly preferably about 10 mm to 15 mm. Even with a conventional PVC-coated roof membrane 13, the fire protection requirements regarding the spread of a fire when the roof membrane is ignited from the outside can thus surprisingly be met.

[0029] This can be achieved by arranging the brackets 17 at a distance between the bracket (17) and the groove (11) on the upper narrow side (14) of the profile bar (6) such that the distance between the top surface of metal sheets (18, 22) placed on the bracket (17) and the underside of the tarpaulin (13) is no more than 50 mm, preferably no more than 25 mm, and particularly preferably about 10 mm to 15 mm. If, for example, trapezoidal sheets 18 with a profile height of approximately 50 mm are to be used, the distance between the bracket (17) and the groove (11) on the upper narrow side (14) of the profile bar (6) is no more than 100 mm, preferably no more than 75 mm, and particularly preferably about 60 mm to 65 mm. If, for example, insulating panels 22 with a thickness of approximately...For insulating panels 22 with a thickness of approximately 40 mm, the distance between the bracket (17) and the groove (11) on the upper narrow side (14) of the profile bar (6) is no more than 90 mm, preferably no more than 65 mm, and particularly preferably about 50 mm to 55 mm. For insulating panels 22 with a thickness of approximately 60 mm, the distance between the bracket (17) and the groove (11) on the upper narrow side (14) of the profile bar (6) is no more than 110 mm, preferably no more than 85 mm, and particularly preferably about 70 mm to 75 mm. For insulating panels 22 with a thickness of approximately 100 mm, the distance between the bracket (17) and the groove (11) on the upper narrow side (14) of the profile bar (6) is no more than 150 mm, preferably no more than 125 mm, and particularly preferably about 110 mm to 115 mm. For insulating panels 22 with a thickness of approx.For insulating panels 22 with a thickness of approximately 140 mm, the distance between the bracket (17) and the groove (11) on the upper narrow side (14) of the profile bar (6) is no more than 170 mm, preferably no more than 145 mm, and particularly preferably about 130 mm to 135 mm.

[0030] Naturally, it makes sense that the brackets 17 are arranged approximately parallel to the grooves 11 for receiving the keder 12 of a roof tarpaulin 13 on the profile bar or rail 6 in order to ensure compliance with the aforementioned distances. Reference symbol list
