Definitions
- the invention relates to a trolley, in particular for underground tunneling, comprising at least the following: Four height-adjustable and movable lifting legs, two trusses, each connecting two lifting legs together, and a plurality of cross members, which connect the trusses together.
- a trolley is usually used to transport a tunnel formwork and spans a construction site passage profile. He takes over the pressure forces to be transmitted from one side wall formwork to the other side wall formwork, as well as the forces to be metered from the slab formwork over the tunnel formwork to the ground.
- From the EP 1136 650 is known in its dimensions adjustable shuttering car. This has two pairs of legs, which are connected to each other via a cross member. The legs and cross members are telescopically variable in length. The two cross members are connected to each other via longitudinal elements, which are also formed telescopically variable in length. As a result, the shuttering car can be reused and adapted quickly and inexpensively to a wide range of different tunnel cross sections.
- each cross member is bolted to the truss and is composed of a plurality of cross member bars, which are bolted together.
- the cross member bars are advantageously made of steel profiles with a top flange and a bottom flange and each have a connection plate on the front side.
- a perforation is present in the upper flange, lower flange and connecting plates, whose holes are arranged in a uniform grid spacing. This allows a construction of any designs in the modular system.
- the disadvantage that the grid mass of the individual cross member bars allow no constructions between these grid masses is rarely crucial. It can thus be overcome, individual cross member bars project-specific made to a dimension deviating from the grid and mounted between the standardized crossbars rods.
- the cross member bars in a length gradation, which corresponds to the grid spacing of the holes.
- This uniform grid of bar lengths and bore grid allows any combination of these standardized crossbar bars.
- At least two locations and / or on the front sides of the girder truss each have a perforation with holes in a grid spacing.
- This second grid spacing need not be the same as the grid spacing of the holes in the cross member bars and in the vertical truss stands on the inside of the truss girder.
- the perforation is dimensioned for stronger screws. It serves to screw the lifting legs to the truss girder.
- the lifting legs are equipped on three sides of the lifting mechanism containing area with flanges. These flanges are provided with a hole with holes in the second grid spacing. This means that the grid spacing of the holes in the flanges of the lifting legs correspond to the grid spacing of the holes on the outside of the truss girder and / or the front sides of the truss girder.
- hip parts for the lifting legs are available. These hip parts do not include a lifting mechanism. They are equipped on four sides with flanges, which are like the flanges of the Hubmechanik comprehensive parts of the lifting legs are perforated. This allows to screw the hip parts to the truss girders and to mount at the hip parts at any point the parts of the lifting legs that contain the lifting mechanism.
- the hip parts and the lifting mechanism containing parts of the lifting legs are joined together axially via Verschraubungsplatten.
- the hip parts then form Hubbeinverinronne.
- the both the lifting mechanism containing parts of the lifting legs as well as the hip parts and the truss girder have a grid perforation, the lifting legs are mounted in different positions on the truss girder. The height of the trolley is thus selectable without providing special parts on the construction.
- truss girder In contrast to the cross beams of trusses is conveniently a welded construction and has a given height as well as a given length.
- the length of the truss girder may be extended by a supplementary truss piece.
- the truss girder is composed of a base, optionally a supplementary truss piece and two end pieces. At both ends of the truss girder this is supplemented with such an end piece on which the lifting legs are arranged.
- the truss supplementary piece having a project-specific length can be inserted between the base and the end piece. This allows the adaptation of the truss girder to a project-specific length, without the need to recreate the attachment points for the lifting legs.
- the lifting legs in the factory can already be in the correct position to the Unscrew end pieces, so that only the truss girder (possibly from the base part and supplementary truss piece) needs to be connected to the end pieces on the construction site.
- FIG. 1 illustrated cross-section shows a two-lane road tunnel while concreting a formwork section.
- the shuttering device 11 arranged therein comprises a transporting carriage 13 and a tunnel shuttering 15.
- the tunnel shuttering 15 is divided into different areas, which are movable differently.
- the trolley 13 spans a construction site passage profile.
- About the trolley ceiling slab 17 is arranged.
- the slab formwork 17 can be lowered together with the trolley.
- the side wall formwork 19, 19 ' also includes a foot end 23, 23', which is pivotable about a second pivot axis 25, 25 'relative to the remaining part of the side wall formwork 19, 19'.
- an individual formwork 18, 18 ' which is project-specific. It comprises the pivot axes 21,21 'and the cam form 27,27'.
- the cam formwork comprises a cam flap 41, 41 ', which can be pivoted toward the transport carriage 13 about the pivot axis 21, 21'. Only in this position, which is pivoted toward the transport carriage, can the transport carriage be lowered.
- the slab formwork 17 is formed from three standard positions and two supplementary layers. Each standard position is formed of standard formwork elements 31, which have a formwork width of 250 cm and a radius of 510 cm.
- the supplementary layers connect outside to the standard conditions. They consist of a supplementary element 32,32 ', which is designed project-specific. Here it serves as a connection to the cam flap 41,41 'of the cam form 27,27'.
- the sidewall formwork comprises four layers. At the top is a supplementary layer of a supplementary element 42,42 'is formed.
- the supplementary element 42,42 ' forms the kink between side wall curve and cam and defines the pivot axis 21,21' for the side wall formwork 19,19 '.
- the subsequent upper layer is a standard position and includes a standard formwork element 33 of width 175 cm with the radius 510 cm.
- the adjoining the standard position lower layer comprises a flat formwork element 35 of width 175 cm with a pivot axis 25,25 'for articulating the noirabBankes 23,23'.
- the foldable foot end 23, 23 ' is articulated to the pivot axis 25, 25'.
- the tunnel formwork 15 is a one-sided formwork.
- the pressure of the concrete can therefore not be absorbed by binding together two walls forming a wall on both sides. Rather, the pressure is transmitted from one side wall formwork 19 'to the other side wall formwork 19.
- the pressure of the slab formwork 17 is supported by the side wall formwork 19, 19 'on the tunnel floor 39, in particular the banquet.
- the resulting forces are on supports 45,45 ', which are partially adjustable in length 45', passed to a cross member 43.
- the cross member 43 is part of the trolley 13th
- FIG. 2 the tunnel formwork is shown in a traversing position.
- the side wall formwork 19,19 'are pivoted to the trolley 13 zoom.
- the trolley 13 is lowered.
- all formwork parts are removed from the wall of the freshly concreted tunnel tube 47, so that the formwork device 11 can be moved on the wheels of the rolling feet 49 via the tunnel bottom 39.
- the formwork can be cleaned in this position.
- At the new position in the tunnel she will return to the in FIG. 1 shown concreting position brought.
- the trolley 13 is shown without the tunnel formwork.
- the trolley 13 comprises wheels in rolling feet 49.
- the rolling feet 49 are formed transversely to the tunnel direction against the lifting legs 51 loading thereon displaceable.
- the lifting legs 51 each carry a two in the tunnel longitudinal direction truss 53.53 '.
- the lifting legs 51 are each arranged in the feed direction of the formwork device 11 in front of and behind the tunnel formwork 15 on the truss 53.53 '. Thanks to the height adjustability of the lifting legs 51, the tunnel formwork 15 can be concreted with its vertex to the vertex height of the tunnel tube 47 (FIG. Fig. 2 ) and lowered to move by about 70 cm.
- the lifting legs 51 comprise a lifting part 51.1 and a hip part 51.2.
- the lifting part 51.1 is equipped on three sides with mounting flanges 75. It can therefore be mounted on the front side (and front or rear) or on the outside of the truss girders 53,53 '.
- the hip part 51.2 is equipped on four sides with such mounting flanges 75. It can therefore be mounted on all sides.
- the trusses have corresponding mounting surfaces. These mounting surfaces and the mounting flanges 75 on the lifting legs 51 are perforated in a 12 cm grid. The perforation allows the lifting legs each to be mounted on a truss-specific height on the truss 53.
- the lifting part 51.1 can be mounted on each of the remaining sides of the hip part 51.2.
- the altitude can be selected according to the grid of perforations.
- the hip part and the lifting part are also, as shown and preferred, screwed together in the axial position.
- a pressure plate 77.1 and 77.2 formed on the hip part and the lifting part. These printing plates can be screwed together.
- the pressure plate 77.1 is formed on a pressure cover 79, to which pressure cover 79 attaches the hydraulic cylinder in the interior of the Hubbeins.
- the cross member 43 are also formed as trusses. They have a top flange 44 and a bottom flange 46, and vertical struts 48, which are bolted together angle stiff.
- the length and the height of the cross member 43 are to be dimensioned project specific.
- the cross member is composed of a modular system. This modular system includes cross member bars 40.1, 40.2, 40.3, 40.4 different length.
- the lengths of the cross member bars 40 are formed in a 10 cm grid.
- Each crossbar 40 has the same end plates 71 and the same cross section of the steel profile.
- the steel profile is a practically square H-profile.
- each cross member bar 40 can be arranged both on the end side for extension of another cross member rod 40, and also on a flange 73 of another cross member rod 40 to form a vertical strut 48. Further, it is possible to insert diagonal bars in the cross member 43. These are formed in the nature of the tunnel formwork 15 supporting columns 45.
- a complementary cross member bar can be made to achieve a cross member length, which is outside the grid.
- the selected 10 cm grid should be sufficiently small, since the rolling feet 49 are each designed to be displaceable by up to 10 cm, so that it is easy to park on a rail not arranged in a 10 cm grid.
- the cross members 43 are formed in the present example with two horizontal bands arranged one above the other, namely a top flange 44 and a bottom flange 46, which extend from truss girder 53 to truss girder 53 'and are screwed thereto.
- These horizontal collars 44,46 are each composed of three cross member rods, namely two 200 cm rods 40.1, which are screwed to the truss girders 53,53 ', and between a 100 cm rod 40.3, with its end plates 71 to the end plates 71 of the 200 cm rods 40.1 is screwed.
- the lower flange 46 and the upper flange 44 are connected to vertical struts 48.
- the vertical struts 48 which are each also a 120 cm rod 40.2 and a 50 cm rod 40.4 are formed.
- the end plates 71 of the vertical struts 48 are on the flanges of the H-profiles of the horizontal collars Screwed 44.46.
- the selected height of the cross members 43 with 170 cm long vertical webs 48 is the maximum height in the present truss girders 53.
- the 50 cm rod 40.4 can be replaced by a 20 cm rod (not shown), for example. It is also possible to replace the 120 cm rod 40.2 with a 100 cm rod 40.3.
- the truss 53 is visible in its longitudinal extent.
- the truss 53 is composed of 4 pieces.
- the basic element 50.1 has a length of 10 meters and is a welded construction.
- An additional truss 50.2 complements the length of the base element 50.1 on the project-specific desired length of the longitudinal truss.
- the supplementary truss girders 50.2 generally have a dimension that is tailored to the truss grid size. In the present example, the framework is placed on a grid of 125 cm and the supplementary truss 50.2 has a length of 250 cm.
- an end piece 50.3, 50.4 is arranged at both ends of the truss girder 53. This end piece is screwed to the base element 50.1 or to the supplementary truss 50.2.
- Each end piece 50.3, 50.4 is equipped with mounting surfaces for mounting the lifting legs 51. In the area of these mounting surfaces, perforated flanges are formed on the opposite side of the end piece 50.3, 50.4, on which cross members 43 can be mounted.
- Such flanges for mounting the cross member are also formed on each vertical strut of the truss girder 53.
- the ends of the base element 50.1, the supplementary truss girder 50.2, and the end pieces 50.3 and 50.4 in total are stiffened with sheets and stiffening ribs. Between the vertical bars of the truss girder 53 diagonal bars for stiffening the truss girder 53 are present.
- struts 55 are hooked into the holes of the cross member bars 40 and the required length up or twisted together.
- These struts 55 are formed as clamping elements and have a central part with two opposing internal threads and two end portions, each with the corresponding external threads. These struts can therefore be used diagonally or orthogonally and serve only as a composite of the support system.
