Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a downstream self-propelled eccentrically supported mobile formwork. Background Technology

[0002] As a core piece of equipment for on-site casting of large-span concrete box girders, the self-propelled mobile formwork plays an irreplaceable role in modern bridge construction. With the extension of transportation networks into complex terrains, bridge projects face increasingly diverse construction conditions, including varying spans, complex alignments, and limited bridge locations. This places unprecedentedly high demands on the adaptability, efficiency, and intelligence of mobile formwork.

[0003] Traditional mobile formwork systems, particularly those designed for single or fixed working conditions, often exhibit insufficient systemic adaptability when faced with the complex and ever-changing construction requirements. Firstly, their structures are typically designed for fixed spans. When the project span changes or the site needs to be moved to a section with a different span, time-consuming and labor-intensive on-site modifications to the main load-bearing structure are required, leading to delays and increased costs. Secondly, conventional formwork methods require significant lateral space, often hindering smooth passage through spans in situations such as parallel double-span bridges, narrow gaps between bridges, or adjacent construction areas, thus limiting their application. Furthermore, for complex alignments such as curved bridges and sloping bridges, the rigid main beams and guide beams of traditional formwork systems often lack effective alignment adjustment mechanisms, making it difficult to guarantee the accuracy of the beam alignment and potentially compromising structural safety.

[0004] Therefore, there is an urgent need to develop a new type of self-propelled mobile formwork for downward movement to adapt to more complex construction conditions. Summary of the Invention

[0005] The main technical problem to be solved by the present invention is to provide a self-propelled eccentrically supported mobile formwork to improve its applicability to complex construction needs.

[0006] To solve the above-mentioned technical problems, the present invention provides a self-propelled eccentrically supported moving formwork, characterized in that it includes a main frame beam module, a support module, a displacement module, and a template module;

[0007] The main frame beam module includes a main beam; the main beam is laterally connected to a supporting bracket; the connection position between the supporting bracket and the main beam is adjustable along the longitudinal direction of the main beam;

[0008] The support module includes a main support leg; the main support leg includes a support column supported on the pier's abutment and a pier-side bracket located on the top of the support column.

[0009] The displacement module includes a moving trolley and a lifting cylinder mounted on the top of the bracket next to the pier; the moving trolley is used to move the main beam along the longitudinal direction, transverse direction, and vertical direction of the bridge; the lifting cylinder is used to lift or lower the supporting bracket.

[0010] The template module includes an outer mold and a bottom mold crossbeam; the bottom mold crossbeam is transversely arranged across the top of the main beam to support the outer mold; the bottom mold crossbeam includes a first sub-crossbeam and a second sub-crossbeam that can move apart or toward each other along the transverse bridge direction; the two sets of side molds of the outer mold are respectively connected to the first sub-crossbeam and the second sub-crossbeam; the second sub-crossbeam is a segmented structure that can be folded and rotated in the horizontal plane.

[0011] In a preferred embodiment, the system further includes a support leg transport module; the support leg transport module includes a longitudinal track disposed on the outside of the main beam and a transport trolley that travels on the longitudinal track; the transport trolley is equipped with a rotating hoist.

[0012] In a preferred embodiment, the main frame beam module further includes guide beams connected to both ends of the main beam; a leveling mechanism is provided at the joint between the guide beam and the main beam, and the leveling mechanism is configured to cause the guide beam to deflect horizontally relative to the main beam.

[0013] In a preferred embodiment, the main frame beam module further includes guide beams connected to both ends of the main beam; the guide beams are hinged to the main beam at the lower part and connected to the main beam at the upper part by a flange and a thickness-adjustable pad, so that the guide beams deflect relative to the main beam in the vertical direction.

[0014] In a preferred embodiment, the template module further includes a support lateral movement mechanism; the support lateral movement mechanism is configured to support the bottom formwork beam on the top of the main beam and to move the bottom formwork beam laterally relative to the main beam via a lateral movement cylinder.

[0015] In a preferred embodiment, the pier-side bracket includes two support beams arranged parallel to each other in the transverse direction of the bridge and at least two equalizing beams erected on top of the two support beams in the longitudinal direction of the bridge; the lifting cylinder is located on top of the equalizing beams.

[0016] In a preferred embodiment, the supporting bracket is connected to the main beam by high-strength bolts; the main beam is provided with at least two sets of holes along the longitudinal direction that mate with the high-strength bolts.

[0017] In a preferred embodiment, the side mold includes at least two sub-side molds that are laterally hinged to each other.

[0018] In a preferred embodiment, the main beam includes a left support beam and a right support beam arranged parallel to each other along the longitudinal direction of the bridge; the main frame beam module also includes a connecting beam connecting the left support beam and the right support beam; at least two of the connecting beams are spaced apart along the longitudinal direction of the bridge.

[0019] In a preferred embodiment, the support column adopts a segmented structure along the vertical direction, which includes multiple detachably connected sub-columns.

[0020] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0021] (1) Adjustable support brackets are set in the main frame beam module. This design allows the support span of the mobile formwork to be adjusted flexibly and quickly according to project requirements without large-scale modification of the main structure, thereby greatly improving the adaptability to bridge projects with different spans and saving modification costs and time caused by project changes. (2) For the case of double-span bridges or adjacent existing structures with limited lateral space, the formwork module adopts a unique asymmetrical opening method with the outer side opening and the inner side folding and rotating, which minimizes the overall width of the mobile formwork in the open state. Only a limited lateral clearance is needed to safely avoid the piers and adjacent box girders, improving the construction capability and application range under complex bridge conditions. (3) The leg transport module can automatically complete the disassembly, transport and forward installation of the rear legs during concrete curing, so that the leg transport process can be carried out in parallel with the main body pouring construction, without occupying the critical path period, realizing the compactness of the construction cycle and the improvement of overall work efficiency. (4) The main frame beam module enables the moving formwork to actively adapt to the bridge's design alignment through the vertical hinge adjustment and horizontal rotation mechanism of the guide beam. Combined with the lateral adjustment function of the formwork system ("folding instead of bending"), it ensures the forming accuracy and structural safety during construction on complex road sections. (5) The support module can directly and reliably transfer the horizontal force during construction to the pier cap, rather than acting on the thin-walled structure of the pier body. This design is particularly suitable for hollow thin-walled piers, effectively protecting the safety of the permanent bridge structure while ensuring the stability of the formwork itself.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0032] like Figures 1-6As shown, this embodiment of the invention provides a downward self-propelled eccentrically supported mobile formwork, which is a downward three-span structure, including a main frame module 1, a support module 2, a template module 3, a displacement module 4, a leg transport module 5, and auxiliary facilities.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the main frame module 1 includes a main beam 11, a guide beam 12, and a connecting beam 13. The main beam 11 is a box-section composite beam, in a double-beam form. For ease of description, the left and right sections of the main beam 11 will be referred to as the left support beam and the right support beam, respectively. Considering transportation limitations, the main beam 11 adopts a layered design, which is connected as a whole on site using high-strength bolts. The main beam 11 is laterally connected to a support bracket 14. The bottom of the support bracket 14 is supported on the top of a lifting cylinder 42, which is mounted on a pier-side bracket 21 of the support module 2. Preferably, the support bracket 14 is connected to the main beam 11 by high-strength bolts. At the connection point with the support bracket 14, the main beam 11 has at least two sets of holes spaced longitudinally to mate with the high-strength bolts, making the connection position between the support bracket 14 and the main beam 11 adjustable along the longitudinal direction of the main beam 11. In this way, the support span of the main beam 11 can be adjusted by changing the installation position of the supporting bracket 14, thereby achieving rapid span change. The guide beam 12 includes a front guide beam and a rear guide beam, which are connected to the front and rear ends of the main beam 11, respectively. The guide beam 12 is spliced ​​from several truss beams, and its main function is to reach the front pier 6 first and provide guidance and support when the moving formwork moves longitudinally through the hole. In order to achieve active adaptation to small radius horizontal curves and vertical slopes, the joint between the guide beam 12 and the main beam 11 has an adjustment function: the joint between the main beam 11 and the guide beam 12 is provided with a horizontal rotation mechanism 15, which allows the guide beam 12 to rotate relative to the main beam 11 in the horizontal plane at a certain angle, which is 14° in this embodiment; the guide beam 12 and the main beam 11 are connected by a lower chord hinge and an upper chord connected by a flange and a pad. By adjusting the thickness of the pad, the vertical deflection of the guide beam 12 relative to the main beam 11 can be achieved, thereby adapting to the slope changes of the line. The lateral rotation mechanism 15 is a hinged joint with a hydraulic rod, which is a mature existing technology and will not be described in detail here. The connecting beam 13 is located between the left and right support beams, and at least two connecting beams 13 are spaced apart along the longitudinal direction of the bridge. Both ends of the connecting beam 13 are connected to the main beam 11 via pins to ensure the overall stability of the main beam 11. Preferably, the connecting beam 13 is designed to separate from the middle and rotate and fold along the horizontal plane around the pin at its root to provide additional lateral passage space.

[0034] like Figure 1 , Figure 3 , Figure 4As shown, the support module 2 serves as the pier-side support foundation for the movable formwork, used to safely transfer construction loads to the pier 6 and the abutment 7. The support module 2 includes three main support legs, a front auxiliary support leg, and a rear hanging leg. The main support legs include a pier-side bracket 21 and a support column 22. The pier-side bracket 21 includes two parallel support leg beams 211 arranged along the transverse direction of the bridge and at least two equalizing beams 212 erected on top of the two support leg beams 211 along the longitudinal direction of the bridge. The lifting cylinder 42 is located on top of the equalizing beam 212, and it distributes the upper load to the two support leg beams 211 by lifting the support bracket 14. Preferably, the support leg beams 211 are box-shaped beams, comprising two symmetrical sub-sections connected by precision-rolled threaded steel bars. The vertical force is transferred to the abutment 7 from below the support leg beams 211 via the support column 22. Especially for the hollow thin-walled pier 6, the supporting column 22 directly transfers the load to the foundation cap 7, avoiding the transfer of the load to the corbels supported on both sides of the pier 6 and thus preventing damage to the pier body. Preferably, the supporting column 22 adopts a segmented structure along the vertical direction, that is, it includes multiple sub-columns that are detachably connected by flanges and bolts, so as to flexibly configure according to different pier 6 heights. To ensure the stability of the movable formwork when subjected to horizontal forces, the supporting column 22 is provided with pier-holding mechanisms 23 at intervals along the height direction. The pier-holding mechanisms 23 are arranged around the outside of the pier 6 and are used to transfer the longitudinal force of the bridge to the pier 6 when the movable formwork moves through the hole. The front auxiliary support leg is installed at the end of the front guide beam, and the rear hanging leg is installed at the end of the rear guide beam. They both serve as temporary support points during the relocation of the main support leg and the conversion of the movable formwork system, ensuring the stability of the formwork posture.

[0035] The template module 3 includes an outer mold 31, a bottom mold crossbeam 32, and a supporting transverse movement mechanism 33. The outer mold 31 includes a bottom mold 311, a web mold, several telescopic support rods 34, and a tilting cylinder. The outer mold 31 is supported on the bottom mold crossbeam 32. The outer mold 31 uses a side mold 312 pressed onto the bottom mold 311, connected by elongated holes, which can adapt to the casting of curved beams. To accommodate the construction of curved beams, the bottom mold 311 of the outer mold module is widened, and the web mold adjusts its alignment by sliding laterally on the bottom mold 311 using infinitely adjustable top screws. The final concrete curved beam is achieved by folding instead of bending. Gaps in the side mold 312 are compensated by small sections of template and T-shaped plates. The outer mold 31 is cambered, and the camber value should be set according to the curve characteristic value generated by the concrete load and the self-weight of the inner mold on the main beam 11 of the movable formwork, as well as the pre-camber required by the design, so that the bridge curve after completion matches the design value. After the movable formwork is in place, the elevation of the bottom formwork 311 is adjusted. The side formwork 312 arches along with the bottom formwork 311, maintaining the same line type and camber, so that it matches the provided or corrected pre-camber curve characteristic value. Several sets of bottom formwork crossbeams 32 are spaced along the longitudinal direction of the bridge. The top of the bottom formwork crossbeams 32 is bolted to the bottom formwork 311. The supporting transverse movement mechanism 33 includes a transverse movement cylinder 332 and at least two supporting mechanisms 331. The supporting mechanism 331 is used to connect the bottom of the bottom formwork crossbeam 32 to the top of the main beam 11, and it has vertical extension and retraction freedom to adjust the inclination angle of the outer formwork 31. The transverse movement cylinder 332 is used to drive the bottom formwork crossbeam 32 to move laterally relative to the main beam 11, thereby adjusting the transverse slope and pre-camber of the outer formwork 31.

[0036] like Figure 4 , Figure 5As shown, preferably, the bottom formwork beam 32 adopts a segmented structure, including a first sub-beam 321 and a second sub-beam 322, which are respectively located on the left and right sides. The left and right side molds 312 of the outer mold 31 are respectively supported on the top of the first sub-beam 321 and the second sub-beam 322. The first sub-beam 321 and the second sub-beam 322 have relative degrees of freedom of movement, either moving apart or towards each other, along the transverse direction of the bridge, so as to realize the opening and closing of the outer mold 31. Preferably, the side mold 312 adopts a segmented structure, including at least two sub-side molds that are laterally hinged to each other, so that the outer part of the side mold 312 can be folded down to avoid lateral structures. The sub-side molds are connected to the first sub-beam 321 or the second sub-beam 322 by the telescopic support rod 34. The second sub-beam 322 adopts a segmented structure and is configured to be able to rotate and fold horizontally along the vertical axis. For the construction of the double-span pier 6, when the formwork of the second pier 6 is opened, the first sub-beam 321 on the side away from the first pier 6 moves outward laterally along with the side formwork 312 and part of the bottom formwork 311 on this side. The second sub-beam 322 on the side closer to the first pier 6 is disconnected from the outermost sub-side formwork so that the sub-side formwork section is flipped down, and the outermost section of the second sub-beam 322 is horizontally rotated and folded in the horizontal plane to bypass the first pier 6.

[0037] The shifting module 4 includes a shifting trolley 41 and a lifting cylinder 42. The shifting trolley 41 is a moving component connecting the main frame module 1 and the pier-side bracket 21 of the support module 2, used to move the main frame beam module 1 along the longitudinal, transverse, and vertical directions of the bridge. The shifting trolley 41 is connected to the lower flange of the main beam 11 or guide beam 12 via an upper hook device, and sits on the track of the support leg crossbeam 211 via a lower traveling device. To adapt to construction on curved sections, the main body of the shifting trolley 41 is divided into upper and lower layers, which can rotate horizontally via a horizontal rotation shaft, thereby adapting to the working conditions where the main beam 11 and the support leg are obliquely intersecting on curved sections.

[0038] like Figure 6As shown, the outrigger transport module 5 includes a longitudinal track located on the outside of the main beam 11 and a transport trolley 51 traveling on the longitudinal track. Specifically, the transport trolley 51 comprises a support frame 511, a lifting column 512, guide wheel sets 513, a traveling wheel box 514, a reverse hook wheel set 515, a rotating lifting device 516, and a lifting mechanism 517. The support frame 511 serves as the main load-bearing structure, and its outer side is slidably connected to the lifting column 512. The reverse hook wheel set 515 is installed on the upper part of the lifting column 512 to achieve horizontal limiting with respect to the support frame 511. The lifting mechanism 517 is connected to the support frame 511 and is used to vertically move the lifting column 512. The upper and lower guide wheel sets 513 are respectively connected to the upper and middle parts of the support frame 511. The traveling wheel box 514 is installed in the middle of the support frame 511 and located above the track. The platform on the outside of the lifting column 512 is connected to the multi-directional rotating lifting device 516 via a rotating main shaft. The transport trolley 51 is used to automatically disassemble, lift, move and precisely install the entire set of main support legs at the rear pier 6 to the predetermined position of the front pier 6 during concrete curing. This process runs parallel to the main construction cycle and does not occupy the critical path schedule.

[0039] The auxiliary facilities include ladders, walkways, operating platforms, and railings to ensure operational safety and convenience. To balance the torque during asymmetrical opening of the formwork, counterweights and supports are installed on the sides of the main beam 11. The hydraulic and electrical control systems of the entire machine adopt a modular design, distributed layout, and centralized control by a PLC to achieve automatic and coordinated control of actions such as formwork frame displacement, formwork opening and closing, and outrigger reversal.

[0040] In a preferred embodiment, the standard work cycle for the mobile formwork to complete the construction of one span of box girder and move to the next span is as follows: First, after the mobile formwork is precisely adjusted and positioned, reinforcement binding, inner formwork installation, and concrete pouring and curing are carried out. During curing, the rear support legs are simultaneously disassembled and moved forward using the support leg transport module 5. After the concrete reaches its strength and prestressing is completed, the main support leg bearing cylinders are operated to retract and demold, the connection between the formwork is released, and the transverse movement cylinder 332 is driven to open the formwork module 3 in the aforementioned asymmetrical manner to create space for the pier 6. Subsequently, the longitudinal movement cylinders on all the moving trolleys 41 are driven to push or pull the entire mobile formwork longitudinally one span. After reaching the desired position, the reverse operation is performed to close and reconnect the formwork. Finally, the main support leg cylinders are raised to adjust the formwork to the new design elevation, and the next construction cycle can begin.

[0041] The technical advantages of the self-propelled eccentric support mobile formwork are explained as follows: (1) The main frame beam module 1 is equipped with adjustable support brackets 14. This design allows the support span of the mobile formwork to be adjusted flexibly and quickly according to project requirements without large-scale modification of the main structure, thereby greatly improving the adaptability to bridge projects with different spans and saving the modification costs and time caused by project changes. (2) For the case of double-span bridges or adjacent existing structures with limited lateral space, the formwork module 3 adopts a unique asymmetrical opening method with the outer side opening and the inner side folding and rotating, which minimizes the overall width of the mobile formwork in the open state. Only a limited lateral clearance is needed to safely avoid the pier 6 and adjacent box girders, improving the construction capability and application range under complex bridge conditions. (3) The leg transport module 5 can automatically complete the disassembly, transport and forward installation of the rear legs during concrete curing, so that the leg transport process can be carried out in parallel with the main body pouring construction, without occupying the critical path period, realizing the compactness of the construction cycle and the improvement of overall work efficiency. (4) The main frame beam module 1 is equipped with a guide beam 12 for vertical hinge adjustment and a horizontal rotation mechanism 15, which enables the moving formwork to actively conform to the bridge's design alignment. Combined with the formwork system's lateral adjustment function of "folding instead of bending," it ensures the forming accuracy and structural safety during construction on complex alignment sections. (5) The support module 2 can directly and reliably transmit the horizontal force during construction to the pier 6 and abutment 7, rather than acting on the thin-walled structure of the pier body. This design is particularly suitable for hollow thin-walled piers, effectively protecting the safety of the permanent bridge structure while ensuring the stability of the formwork itself.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Any technically equivalent modifications made based on the content of this specification shall fall within the protection scope of the present invention.
