Description

U-profile beam of a deck, ship, tribune, ladder, scaffold or dais.

The invention relates to a profile beam in U according to the preamble of claim 1.

From document DE 35 42 610 A1 a known fast assembly ship roof with a modular roof on which the roof covering elements are placed and supported on U-shaped upper cords of roof trusses also designated in practice modules supports. These trusses of roof they present besides the upper cords also lower cords, vertical bars and diagonal bars, which are sized according to metal construction engineering and soldiers with each other. The upper cords are configured as U-shaped bars open up whose U-shaped wings form vertical wings and whose base or bottom is constituted by nerves horizontal welded with vertical bars and bars diagonals of roof trusses. In the longitudinal direction of the respective roof truss are welded to certain distances at the bottom of your upper cord in the center of the nerve horizontal safety flanges protruding upwards. These are properly configured longer, for a safety opening for a wedge, that the vertical wings of the upper cord with the help of which the elements of top cord cover.

This type of construction is accredited in the practical and facilitates quick assembly or disassembly and is appropriate to cover large openings. However, for assembly it In any case, it requires a crane. Roof trusses relatively heavy are conceived with their U-profile bars for a specific use in roof constructions. Besides cover elements, in safety flanges can be connected also other fasteners such as brackets railing according to DE 297 11 346 U1 or devices fall safety aids according to document DE 20 2004 001 314 U1. However, the fixation positions available for this purpose they are limited to the positions of the flanges of safety fixedly welded with U-profile bars in the upper cords of roof trusses.

An alternative possibility to perform roof constructions are known, for example, from document DE 100 28 262 A1 which refers to a roof structure with awning. This type of roof structure is made using the called lattice beams, such as they are known as parts in series for the construction of scaffolding. These lattice beams that they form the roof trusses have a tubular top bead, a tubular lower bead and ascending tubular diagonal bars and descending, as well as vertical tubular bars arranged approximately perpendicular to the upper cord and to the lower cord. Superimposed on the upper cords of the lattice girders a connection profile unit is connected which runs along the entire length of the respective roof truss. This unit comprises a U-profile that runs through the entire length of the lattice beam, on whose lower side and perpendicular to it support bars are welded tubular at whose lower ends opposite the U-profile is welded a respective articulated tubular coupling. With the help of These articulated tubular couplings can be fixed detachable connection profile unit in the upper cords of lattice beams. With this type of structure can occur, depending on the geometric configuration and the arrangement of the Diagonal tubular bars and / or vertical beam bars latticework, situations in which tubular couplings collide with one or more of these tubular diagonal bars and / or vertical bars, so at these points it is not possible to fix the connection profile unit on the lattice beam using the articulated tubular coupling. From the above an increased security risk results. For fixing the awning of a canopy cover in the connection profile unit a square timber is inserted in the U-profile of the same whose upper side ends flush with the ends directed towards above the vertical ribs of the U profile unit. The awning is fixed by metal clips on the squared wood and additionally secured by a coating profile open down hat-shaped, which in turn is fixed by means of a screw that crosses the awning and is screwed into the squared timber. This type of fixation is relatively complicated.

The applicant's known in practice connection profile units configured similarly for its use in modular roofs. For fixing the elements of roof of these, at the bottom of the U profile of the profile unit of connection are welded safety flanges that protrude towards above, as described above in relation to the DE 35 42 610 A1, so they are presented disadvantages

From document DE 31 07 416 A1 a known supporting structure for mountable and removable decks or warehouses in which I-profile beams with double ribs are used transversal as vertical supports and also as beams of roof. The I profile beam is composed of two nerves that they run spaced parallel to each other whose ends they are joined with a transverse wall to form a hollow profile in the form of a box. At both ends of the nerves is provided a respective I flange whose flange parts extend towards out perpendicular to the nerves, seen from the plane longitudinal longitudinal of the beam, and run along the edges of the nerves. One of the transverse walls extends at a distance from the respective I flange inside the beam, so that an open hole is formed outward for the Insertion of a wooden plank. The opposite transverse wall is configured as a T-shaped groove. This is used to accommodate a hammer-shaped head of a head screw in hammer shape, with which it can be fixed on the profile beam in I a component provided with an oblong hole, screwing and tightening a nut on the hammer-shaped head screw. In order to be able to fix on the beam profile in I also components not provided with oblong holes, a rectangular clamping plate whose round hole passes the hammer head screw. The assembly of this beam relatively heavy I profile is not possible without a crane and the roof elements fixed on a wooden plank, which should be handle and transport separately, can only be removed from laborious way.

Similar I-profile beams with double ribs They are known for example from DE 30 45 389 C2. From documents DE-OS 28 50 098 and DE-OS 28 50 545 other beam profiles are known in I in relation to a scaffolding element with a piece complementary interchangeable. These beam profiles in I present  at their ends on the flange side a respective shaped groove of T open out, in which an element can be inserted U-shaped auxiliary manageable separately, which in your nerve that joins the two U-wings is provided for this purpose with a protrusion in T shape directed out. An auxiliary element of this type can be used to hook the claws of planks or plates framed serving as scrolling surfaces or job. Auxiliary elements of this type must be handled, Store and transport separately.

The fast assembly ship 10 according to one of several advantageous embodiments of the invention, represented schematic in figure 1 in front view, presents a structure base that serves as a support in the form of scaffolding 11 placed in the sides that are formed for example with racks of support. In these base structures are supported several trusses of roof 12 of which each can present an element of 12.1 central ridge and several 12.2 truss elements assembled by flanges and / or tubular joints with the elements of coupling and corresponding joints, so it can be constituted a contour of gable roof.

As shown schematically by way of example in figure 2, instead of each line 17.1 to 17.4 you can an individual roof truss 12 is provided, shown here four roof trusses 12 next to each other or one behind other. It is understood that it is possible to place an arbitrary number of roof trusses 12 one after another or side by side.

Roof trusses 12 are configured as Lattice beams 18, preferably aluminum, such as used as standard parts in scaffolding construction. Present upper cords 20, lower cords 21, vertical bars 22 and diagonal bars 23. Due to the slope of the roof, the Vertical bars 22 have a not exactly vertical position. However, they are called vertical bars. These laces 20, 21 and bars 22, 23 are welded forming a lattice beam 18.

In the upper cord 20 in this case tubular of lattice beam 18, which forms a bearing element 46, is superimposed on a U 30 profile beam according to the invention and fixed detachably in that by a connection coupling 60 configured as tubular coupling. The U 30 profile beam it presents an open U-profile 35 that presents wings of support 38.1, 38.2, arranged in parallel with each other and in relation to the central longitudinal plane 36 of the U-profile 35 and joined by a transverse wall 37, which have at their ends free support edges 39.1, 39.2 for an overlapping element 40. In the exemplary embodiment of the invention represented in the Figure 3, the superimposed element 40 is constituted by elements of roof 41 of a modular roof. However, it is understood that as an overlapping element 40, a roof of awning or a gateway and / or surface element of work, in particular a scaffolding floor or hitching means auxiliary 57 thereof such as for example claws and the like, such as shown by way of example in figure 4.

The U-profile 35 of the U-profile beam of lightweight extruded metal is formed as a single piece with a connecting piece 45, used to fix and support the U-profile 35 on the elongated support member 46, here on the cord upper 20 of the lattice beam 18. It is understood that the beam of U-profile 30 is appropriate and is intended to be fixed by connection coupling 60 also in other elements carriers, for example in a scaffolding tube.

The U-profile beam 30 has a groove of guide 50, which extends transversely to the support wings 38.1, 38.2, limited by transverse wall 37 and open in the direction towards the support edges 39.1, 39.2 of the support wings 38.1, 38.2 and towards the inner sides 42.1, 42.2 thereof. Forming a notch 51, this guide groove 50 is limited by 52.1, 52.2 grip ribs behind the groove, arranged shape distanced from each other and along the inner side 42.1, 42.2 of the two support wings 38.1, 38.2, extending each starting from these sides inwards towards the longitudinal plane central 36. The nerves 52.1, 52.2 grab behind the slot are configured here approximately perpendicular to the support wings 38.1 and 38.2 and are in a horizontal plane in common, perpendicular to the longitudinal plane central 36.

In a guide groove 50 there is a block of slide 53 of a fixing means 55 used for fixing of one or more overlapping elements 40 in the profile beam in U. Guide slot 50 is configured in the form of a rail guide 54 for the sliding block 53 extending in the direction length 62 of the U-profile beam 30 over the entire length of the U-profile beam 30, in figures 3 and 4 in one direction perpendicular to the sheet plane. This allows to move the block of slide 53 in such a way in the guide groove 50 in the direction longitudinal 62 of the U-profile beam 30 that can be positioned  and fix in arbitrary positions along the guide rail 54

Sliding block 53 presents in a section transverse perpendicular to cross-sectional views represented in figures 3 and 4, that is to say in a cutting plane which runs parallel to the longitudinal direction 62 of the beam U-profile 30, a maximum width that is less than the distance minimum between opposite ends of nerves 52.1, 52.2 of grip behind the groove, which corresponds to the width of the notch 51. Therefore, in a tight state it is possible carry the slide block 53, starting from its locked position shown in figures 3 and 4 and rotating it around its axis vertical 70, in this case at approximately 90 °, to a position in which can be removed from the guide groove 50 through the notch 51 together with the remaining parts of the fixing means 55 configured as a quick clamping element. The assembly of sliding block 53 in the guide groove 50 can be carried out in reverse.

Sliding block 53 is attached preferably rigidly rotated with a safety flange 76.1, 76.2 configured in the form of a sword or bolt extends approximately perpendicular to the block of sliding, which has a cross section approximately rectangular, in the opposite direction and extends in the assembled state represented through notch 51 of the guide slot 50 approximately parallel to the support wings 38.1, 38.2 and throughout them. The security flange 76.1, 76.2 has such a length that it protrudes in the assembled state of such way of the support edges 39.1, 39.2 of the support wings 38.1, 38.2 of the U-profile 35 of the U-profile beam 30 that an element clamping 77, configured here as clamping plate or as perforated disc 78, which overlaps overlapping elements 40 or cover elements 41, placed one above the other in the area of gasket in figure 3, or the auxiliary coupling means 57 represented in figure 4 of the gateway elements 58 and / or of work surface, respectively, can be tensioned separable by means of a wedge 80 that crosses an opening of safety 79.1, 79.2 of safety flange 76.1, 76.2 which runs transversely to safety flange 76.1, 76.2. Such as shown in assembled and tensioned state in figures 3 and 4, overlapping elements 40 or roof covering elements 41 or the auxiliary attachment means 57 fixedly connected, preferably by welding, with elements 58 of gateway and / or work surface, respectively, are fixed between the fastener 77 and the support wings 38.1, 38.2 after having wedged wedge 80 into the opening of security 79.1, 79.2.

Wedge 80 presents in the area of its end opposite the end of nailing a means of security against loss, here in the form of a rivet 85, so wedge 80 is joined by captive shape with safety flange 76.1, 76.2. Rivet 85 presents for this purpose a width or length, respectively, which is greater than the width of the security opening 79.1, 79.2 or, expressed more generally, rivet 85 protrudes from the outer surface of wedge 80 to such an extent that it is not possible separate wedge 80 from safety flange 76.1, 76.2 without permanent deformation or destruction of rivet 86 and / or wedge 80 and / or safety flange 76.1, 76.2. In the examples of embodiment shown, also the slide block 53 and the element  clamping 77, configured here as perforated disc 78, are connected securely with the safety flange 76.1, 76.2, whereby the sliding block 53, the clamping element 77, the wedge 80 and safety flange 76.1, 76.2 constitute a unit or An unmissable module.

As shown by way of example in the Figure 4, the fixing means 55 configured with the block of slide 53 can serve or be advantageously configured also for fixing a lifting insurance 56 so that gateway and / or work surface elements 58, provided with auxiliary hooking means 57 such as hooks or claws, is not lift off the support edges 39.1, 39.2 of the support wings 38.1, 38.2.

In the preferred embodiments of the invention, shown in Figures 3 and 4, it is further provided that the connecting piece 45 of the U-profile beam 30 present on both sides of the central longitudinal plane 36 a respective fixing wing 59.1 , 59.2 for the connection coupling 60 which in this case is separately manageable and is configured as a tubular coupling consisting of a coupling half housing 61. Unlike the known construction types of the prior art, this connection coupling 60 can be fixed detachably on the U-profile beam 30 configured according to the invention in various arbitrary positions along the U-profile beam 30 on the fixing wings 59.1 and 59.2 thereof. The U-profile beam 30 can be fixed by means of the connection coupling 60 in the elongated supporting element 46, configured here as the upper bead 20 of a lattice beam 80, or is fixed thereon according to the mounting positions represented in the Figures 3 and 4. For this purpose, the two fixing wings 59.1 and 59.2, configured here as fixing rail 63.1, 63.2, extending in the longitudinal direction 62 of the U-profile beam 30 continuously throughout the entire length of the U-profile beam, in which fixing pieces 71.1 and 71.2 of the connection coupling 60 can be fixed in various arbitrary positions along the U-profile beam 30. In this way it is possible to arrange and fix the connection coupling 60 in arbitrary positions along the U-profile beam 30 for fixing it to the supporting element 46, without collision with adjacent components such as braces. This guarantees optimum security. Unlike the coupling half shells known in the prior art, the coupling half shell 61 is manufactured as an extruded metal profile
light.

Fixing wings 59.1 and 59.2 comprise each a support elements 68.1, 68.2 each presenting 69.1, 69.2 rear grip surfaces that extend into opposite direction to the support element 46, in this case the cord upper 20, towards the side of the U-profile beam 30 presenting the U-35 profile, with the help of which a lateral support of fixing parts 71.1, 71.2 of connection coupling 60 when it is fixed on the U profile beam 30 fixing the beam U-profile 30 on bearing element 46. In the fixed state, fixing parts 71.1 and 71.2 of connection coupling 60 they are therefore coupled in positive union with the elements of support 68.1, 68.2 or with fixing wings 59.1, 59.2, respectively.

In the embodiments shown in Figures 3 and 4, the U-profile beam 30 according to the invention it has a housing groove 65 in its connection piece 45 configured between fixing wings 59.1 and 59.2 which is open outward towards the bearing element 46 and extends in the longitudinal direction 62 of the U-profile beam 30 also of continuously along the entire length of the U profile beam. This housing slot 65 can serve to accommodate a piece of a fixing means connected with the bearing element 46, configured in this case as a screw 67 with a screw head 66. So Thus, the screw head 66 protruding from the surface exterior of the bearing element 46, in this case tubular, it can be accommodated in the housing slot 65 so that the beam of U-profile 30 can be placed according to the intended use and fixed surely also on pieces that protrude in this way from the bearing element 46.

In the embodiments shown in the Figures 3 and 4, the fixing wings 59.1 and 59.2 of the element superimposed 40 on the U profile beam 30 on the bearing element 46 tubular, formed here by an outside circle diameter, are configured with a cylindrical circular contact surface whose radius 64.1, 64.2 corresponds to the outer radius of the element tubular bearing 46. This way you get a contact in positive and optimized union regarding element tensions superimposed 40 of the U profile beam 30 with the element bearing 46. However, it is understood that, depending on the outer geometry of the respective bearing element, the bearing surfaces of the superimposed element assigned to that they can be configured in a way adapted to the respective contour of these bearing elements, that is, they can be configured for example bevelled with a flat surface and in the straight cross section. Therefore, the U 30 profile beam according to the invention it can be mounted on any type of elements carriers, in particular in any type of scaffolding tubes or lattice beams, in particular with a cross section circular, so that a field of application is particularly wide of this U 30 profile beam.

The range of application of the U-profile beam 30 is further expanded by the fact that in the U 35 profile of the same or at the support edges 39.1, 39.2 of the support wings 38.1, 38.2 can also be attached gateway elements and / or work surface, particularly scaffolding floors and preferably auxiliary hooking means 57 as hooks or claws of such gangway and / or surface elements 58 of work, which by means of quick clamping element 75 can look at the profile beam at U 30 or secure at the beam of U-profile 30 by lifting insurance 56. So therefore, the U 30 profile beam can be used for example also for mounting surface scaffolding based on beams lattice and / or scaffold components that do not belong to a system.

An example of realization of this type of the U-profile beam 30 according to the invention of a supporting structure, in particular of a scaffolding or of a dais or a grandstand or a ladder, which is fixed in a tubular bearing element 46 by means of a coupling of connection 60 and on whose U support wings 38.1, 38.2 hooks fixing 84, which form auxiliary fixing means 57, of floors of scaffolding 83 constituting gateway elements 58 and / or of Work surface are secured with the help of an element of clamp 77 configured as safe against lifting 56 fixed by means of a quick clamping element 75 with wedge 80. The identical elements are provided with the same symbols of reference than in figure 3.

Unlike the embodiment example represented in figure 3, in the exemplary embodiment according to the Figure 4 is provided in the safety flange 76.2 an opening of 79.2 security rotated approximately 90º from the opening Safety 79.1. As a consequence, wedge 80 is arranged also displaced by approximately 90º, so now extends approximately parallel to the direction length 62 of the U-profile beam 30. This makes it possible to arrange the usual 80 wedges in scaffolding construction so that they occupy little space and in a very visible way under aspects of security. Apart from the differences mentioned above, the fixing means shown in figure 4 is configured as the same way as the fixing means 55 in figure 3. Also configured in the same way are in figures 3 and 4 U-profile beam 30 and connection coupling 60. No However, it is understood that these elements may be also configured differently within the framework of the invention.

It is further understood that the extruded U 30 profile beam of light metal can be shortened in situ to the desired extent and can then be used without restrictions.
