"Movable structure suitable for supporting a formwork of a new bridge section in cantilever"
TECHNICAL FIELD
The present invention is related to a movable structure supported in a previously constructed bridge section and suitable for supporting a cantilever formwork of a new bridge section.
PRIOR ART
Movable structures supported in a previously formed bridge section which support the cantilever formwork of a new bridge section are known.
WO20101 18773A1 discloses a movable structure comprising at least one pair of bearing assemblies bearing the load of the new bridge section, each bearing assembly comprising a part extending on the new section, a second part through which the bearing assembly is fixed to the already constructed bridge section and a central part between both parts. The movable structure comprises adjustment means for each bearing assembly for orienting each bearing assembly such that the first part of the bearing assembly is not arranged substantially aligned with the web of the new bridge section, which allows having greater access to the formwork.
On the other hand, ES2357731 T3 discloses a movable structure comprising several bearing assemblies and cross beams fixed directly and respectively to the first part and to the central part of each bearing assembly, each cross beam bearing the weight of the formwork of the new bridge section. These beams have large dimensions given the heavy weight they must bear.
DISCLOSURE OF THE INVENTION
The object of the invention is to provide a movable structure for supporting a cantilever formwork of a new bridge section according to the claims.
The movable structure comprises at least two bearing assemblies suitable for bearing the weight of the new bridge section comprising at least two webs and a floor. Each bearing assembly comprises a central part which is supported in a previously constructed bridge section, a first part extending on the previously constructed bridge section, being fixed to said previously constructed bridge section and a cantilever second part extending from the central part towards the new bridge section. The movable structure further comprises a front bracing transversely coupled to the second part of each bearing assembly, and beams arranged substantially transverse to the formwork, suitable for supporting said formwork, the beams being suspended from the front bracing.
The structure further comprises at least two main tie beams each of which is arranged substantially aligned with the upper end of the corresponding web of the new bridge section and couples the corresponding beam which bears the weight of the floor and the webs to the bearing assembly.
Therefore, the beam or beams which bear most of the weight of the new bridge section, between approximately 70 and approximately 80% of the weight, directly transfer the stresses to the bearing assembly through the main tie beams, the mechanical requirements for the front bracing therefore being lower. An optimized structure in relation to dimensions that complies with the mechanical requirements is therefore obtained. The structure can be formed in modules, allows varying the separation between bearing assemblies, thereby being adapted to different bridge sections with a minimum variation of elements.
These and other advantages and features of the invention will become evident in view of the figures and the detailed description of the invention.

DETAILED DISCLOSURE OF THE INVENTION
Figures 1 to 5 show a movable structure 1 suitable for supporting a cantilever formwork 40, shown in Figures 4 and 5, of a new bridge section 3 according to the invention. The movable structure 1 is suitable for being fixed in a previously constructed bridge section 3', shown in Figure 4, while concreting the new bridge section 3, shown in Figure 5, and so forth until the bridge is completed. The bridge sections 3,3' are substantially continuous and are arranged aligned with one another. Both the new section 3 and the previously constructed section 3' respectively comprise webs 5, 5', a floor 6, 6' and a deck 2, 2'. In the embodiments shown, each section 3,3'
comprises two webs 5, 5' although in other embodiments each bridge section could comprise more than two webs.
In the embodiment shown in the figures, the movable structure 1 comprises two bearing assemblies 10, suitable for bearing the weight of the new bridge section 3, a front bracing 20 transversely coupled to the bearing assemblies 10 and cross beams 4 arranged substantially orthogonal to the formwork 40, suitable for supporting said formwork 40 suspended from the front bracing 20. Each bearing assembly 10 is arranged substantially longitudinally aligned with respect to the web 5' of the previously constructed bridge section 3'. Although in the embodiment shown the webs 5, 5' are arranged substantially orthogonal to the floor 6, 6' and to the deck 2, 2', in other embodiments, the webs 5, 5' can be arranged forming an angle with respect to the deck 2, 2', in which case each bearing assembly 10 will be arranged aligned on the attachment of the respective web 5 with the deck 2.
The movable structure 1 comprises at least two main tie beams 7 each of which is arranged substantially aligned respectively with the upper end of the web 5 of the new section 3 of bridge. Each main tie beam 7 is arranged substantially vertical, coupled to the front bracing 20. In the embodiment shown in the figures, the webs 5 are arranged substantially orthogonal to the floor 6 and to the deck 2, each main tie beam 7 therefore being arranged substantially aligned with the respective web 5. In other embodiments, the webs 5 can be arranged forming an angle with respect to the deck 2 in which case each main tie beam 7 will be arranged aligned with the upper end of the respective web 5.
Each main tie beam 7 couples the corresponding cross beam 4 to the corresponding bearing assembly 10, transmitting the weight of the floor 6 and the webs 5 to the corresponding bearing assembly 10. The main tie beam 7 has a substantially rectangular section. The cross beam 4 is a beam with a substantially l-shaped section, formed by two facing beams 4a, 4b with a substantially C-shaped section, as shown in Figures 1 and 2, one end of the main tie beam 7 being coupled between both beams 4a, 4b facing one another.
In the embodiment shown in the figures, the movable structure 1 comprises two main tie beams 7, although in other embodiments it can comprise as many tie beams as
there are webs in the bridge section. The two main tie beams 7 are arranged substantially parallel to one another, separated a distance A, shown in Figure 5, said distance A being the mean distance between the webs 5. Most of the weight of the new bridge section 3, substantially between approximately 70 and approximately 80% of the weight, is therefore transmitted directly to the corresponding bearing assembly 10 through the cross beam 4 and the corresponding main tie beam 7.
On the other hand, the front bracing 20 comprises at least one lattice structure 21 and at least two reinforcements 23, the lattice structure being coupled to the reinforcements 23 and each main tie beam 7 being coupled to the corresponding reinforcement 23. Each lattice structure 21 comprises cross bars 21 a arranged substantially parallel to one another intercalated with inclined bars 21 b coupled between two bars 21 a arranged substantially parallel to one another. Each reinforcement 23 is arranged substantially orthogonal to the cross bars 21 a arranged substantially parallel to one another. Each reinforcement 23 is arranged substantially aligned with the corresponding main tie beam 7. Each reinforcement 23 has a substantially rectangular section. Since most of the weight of the new bridge section 3 is transmitted to the bearing assembly 10 through the main tie beam 7, optimized lattice structures 21 lighter than those known in the state of the art are obtained given that said lattice structures 21 do not have to bear most of the weight of the formwork 40. Greater versatility for using the same lattice structures 21 in movable structures for the construction of different bridges is further obtained given that the elements which should be sized according to the stress that the main tie beams 7 and the reinforcements 23 must withstand, having to adapt only the length of the lattice structures 21 in each case according to the width of the corresponding bridge section.
On the other hand, the movable structure 1 comprises at least one auxiliary tie beam 7' which couples the corresponding cross beam 4 to the front bracing 20. The auxiliary tie beam T is arranged at one end of the cross beam 4, substantially parallel to the main tie beam 7. Each auxiliary tie beam 7' is coupled to an end of the cross beam 4, housed between the two beams 4a, 4b configuring each cross beam 4, and to a cross bar 21 a of the lattice structure 21 of the front bracing 20. On the other hand, the formwork 40 shown in Figures 4 and 5 comprises a lower
formwork 41 , an outer formwork 42 and an inner formwork 43, each of which is fixed to the corresponding cross beam 4 through respective hangers 44 arranged in a swing-like manner. The lower formwork 41 bears the floor 6 and the webs 5 and is supported in transverse members 47, 48 shown in Figures 4 and 5, arranged substantially parallel to one another, substantially transverse to the bridge section. The transverse members 47, 48 are attached to one another through longitudinal members, not depicted, arranged substantially longitudinal to the bridge section. The weight of the floor 6 and of the respective webs 5, as well as of the lower formwork 41 , is supported by the transverse members 47, 48. One of the transverse members 47, arranged at a free end of the new bridge section 3 is fixed to the respective beams 4 of the movable structure 1 through the respective hangers 44. On the other hand, a transverse member 48 is fixed directly to the floor of the constructed bridge section 3'. On the other hand, the movable structure 1 comprises work platforms 46 supported by the members 47, 48 and by the beams 4.
On the other hand, each bearing assembly 10 comprises a central part 13 which is supported in a previously constructed bridge section 3', a first part 1 1 extending on the previously constructed bridge section 3' and a cantilever second part 12 extending from the central part 13 towards the new bridge section 3. Both the first part 1 1 and the second part 12 are coupled to the central part 13, each of them configuring with the central part 13 a substantially triangular structure. In the concreting position, each bearing assembly 10 is arranged fixed to the previously constructed bridge section 3' through the first part 1 1 . In other embodiments not depicted, the movable structure 1 can comprise more than two bearing assemblies 10 according to the number of webs 5 comprised in the bridge section 3.
On the other hand, the movable structure 1 comprises, in addition to the front bracing 20, a rear bracing 30 transversely coupled to the central part 13 of each bearing assembly 10. The front bracing 20 and the rear bracing 30 are reinforced by means of longitudinal beams 35 which are coupled transversely to both bracings 20, 30, as shown in Figures 1 to 4. On the other hand, the movable structure 1 comprises a coupling 45 shown in detail
in Figure 7, through the reinforcement 23 and the main tie beam 7 which are coupled to the bearing assembly 10. The second part 12 of the bearing assembly 10 comprises two walls 17 arranged substantially parallel to one another at one end 14, delimiting a cavity 18 where the main tie beam 7 is partially housed. The coupling 45 also comprises at least one plate 26 which is fixed at one end to the reinforcement 23, the other end of the plate 26 being at least partially housed in the cavity 18 defined by the walls 17 of the second part 12, and a bolt 9 which fixes the plate 26 and the main tie beam 7 to the second part 12 of the bearing assembly 10. To that end, the plate 26, each wall 17 and the main tie beam respectively include a hole which the bolt 9 goes through. Furthermore, each plate 26 comprises at least one projection 27 extending substantially orthogonal and on which the corresponding lattice structure 21 is fixed. In the embodiment shown in the figures, the coupling 45 comprises two plates 26, each of which is fixed to the reinforcement 23, facing the corresponding wall 17 of the end 14 of the corresponding bearing body 10. Each plate 26 shown in the embodiment includes two projections 27 arranged substantially parallel to one another, between which an end of the lattice structure 21 is bolted.
On the other hand, the coupling 45 comprises at least two anti-rotation members 8 shown in Figure 7, passing through the walls 17 and the corresponding plates 26 through respective holes 19, preventing the rotation of the front bracing 20 with respect to the respective bearing assembly 10.
On the other hand, the movable structure 1 comprises guiding means 37, shown in Figure 1 to 4 and 6, suitable for moving the bearing assemblies 10 together with the bracings 20, 30 and the formwork 40 in a guided manner once the new bridge section 3 has been concreted. The guiding means 37 comprise rails 38 arranged substantially parallel to one another and fixed to the deck 2' of the previously constructed bridge section 3', and rolling elements 39 coupled to the central part 13 of each bearing assembly 10 and suitable for moving along the respective rail 38.
Furthermore, the movable structure 1 comprises anchoring means 36, shown in Figure 1 to 4 and 6, which fix each bearing assembly 10 to the previously constructed bridge section 3' and particularly to the deck 2' of said previously constructed bridge section 3', thereby preventing movements with respect to the rails 38 and overturning of the bearing assemblies 10 due to the load supported in
cantilever in the concreting position. The anchoring means 36 fix an end of the first part 1 1 of each bearing assembly 10 to the deck 2'. Both the anchoring means 36 and the rolling elements 39 are known in the state of the art, so it is not considered necessary to describe them in detail.
On the other hand, the movable structure 1 comprises operating means, not depicted, acting on each bearing assembly 10 for raising said bearing assembly 10 with respect to the rails 38 and for moving the bearing assembly 10 together with the bracings 20, 30 and the formwork 40. Therefore, in the concreting position, the anchoring means 36 keep the bearing assembly 10 fixed to the constructed bridge section 3', and the operating means keep the central part 13 of the respective bearing assembly 10 raised, separating the rolling elements 36 with respect to the corresponding rail 38. In this position, once the new bridge section 3 has been concreted and tensioned, the movable structure 1 has to be moved to concrete a new bridge section. To that end, first the rail 38 is moved to the new concreting position and is fixed to the bridge section previously concreted. The operating means then lower the central part 12 of the respective bearing assembly 10 until it contacts the corresponding rail 38 again. In said position, the anchoring means 36 of the bearing assembly 10 are released, allowing the operating means to move the respective bearing assembly 10 with the bracings, the beams 4 and the formwork 40 to the new forming position, again anchoring each bearing assembly 10 to the constructed bridge section through the anchoring means 36. These steps are repeated successively until the bridge is completely built.
