Technical Field
[0001] This utility model relates to the technical field of hanging basket construction equipment, and in particular to an upper-bearing mobile formwork bridge building machine. Background Technology
[0002] Mobile formwork bridge-building machines are construction machines that use self-contained formwork and piers or abutments as supports to cast concrete on-site for bridges. Their main features include high-quality construction, simple operation, and low cost. They are widely used in the construction of continuous beams for highway and railway bridges and are considered a relatively advanced construction method.
[0003] Existing mobile formwork bridge-building machines can be divided into upper-bearing and lower-bearing types. Due to the limitations of the load-bearing capacity of lower-bearing mobile formwork bridge-building machines, they are only suitable for small and medium-sized single-box single-cell bridges. For large bridges, such as... Figure 1 The multi-cell bridges and cable-stayed bridges shown primarily utilize steel box girder mobile formwork bridge-building machines. The main truss of these machines is a steel box structure, which improves the overall integrity of traditional hanging baskets and enables automatic adjustment and movement of the formwork.
[0004] However, the existing steel box-type upper-bearing mobile formwork bridge building machine has a main truss of steel box structure arranged along the bridge direction on both sides of the beam. The space on both sides of the steel box structure is too small, requiring a complex external formwork support system to support the external formwork system, resulting in a huge bridge building machine structure. Utility Model Content
[0005] In view of this, the present invention provides an upper-bearing mobile formwork bridge building machine, which sets the main truss into multiple main truss units in the form of a frame structure. This can increase the space on both sides of the main truss, and facilitate the installation of front C-shaped hooks and middle C-shaped hooks at both ends of the front and rear upper crossbeams suspended on the main truss units to support the outer formwork system through the outer guide beam. Therefore, it can effectively simplify the structure of the main truss and the outer formwork support system, thereby effectively simplifying the structure of the upper-bearing mobile formwork bridge building machine and reducing the space occupied.
[0006] A top-bearing mobile formwork bridge-building machine includes a main truss, a bottom basket, and an outer formwork system. The bridge-building machine also includes an outer guide beam. The main truss includes at least two sets of main truss units arranged sequentially along the bridge direction at the top of the beam. Each main truss unit is a frame structure. One end of each main truss unit has a first hanging part, and the middle of each main truss unit has a second hanging part. The front and rear upper crossbeams of the bottom basket are detachably suspended from the first and second hanging parts of the main truss units near the ends of the beam. The front and rear upper crossbeams are respectively provided with a front C-shaped hook and a middle C-shaped hook at opposite ends along the transverse direction. The outer guide beam is spaced along the transverse direction on the hook parts of the front and middle C-shaped hooks. The outer guide beam is arranged along the bridge direction, and the outer formwork system is slidably mounted on the outer guide beam along the transverse direction.
[0007] In one embodiment, the external mold system includes an external mold platform, and an upper external mold template and a lower external mold template connected sequentially from top to bottom along the height direction of the beam; wherein, the upper external mold template includes a first part and a second part; the first part and the second part are slidably connected along the height direction of the beam; the external mold platform is disposed on top of the lower external mold template, the upper external mold template is movably disposed on the external mold platform along the transverse direction of the bridge, and the upper external mold template and the lower external mold template are detachably overlapped with the beam; the external mold platform is slidably disposed on the outer guide beam along the transverse direction of the bridge.
[0008] In one embodiment, the top of the outer mold platform is provided with a telescopic component connected to the bottom of the first part, the telescopic component being used to drive the first part to slide relative to the second part along the height direction of the beam.
[0009] In one embodiment, the outer mold system further includes a support platform disposed on the outer mold platform, the telescopic component is disposed on the top of the support platform along the height direction of the beam, and the second part is connected to the side of the support platform near the beam; the bottom of the support platform is provided with a traveling mechanism, the traveling mechanism is disposed on the outer mold platform, and the traveling mechanism is used to drive the support platform to move along the transverse direction of the bridge.
[0010] In one embodiment, the bridge-building machine further includes an inner guide beam and an inner formwork system; the inner guide beam is detachably connected to the beam and suspended below the beam along the bridge direction, and the inner formwork system is slidably disposed on the inner guide beam along the bridge direction.
[0011] In one embodiment, the bridge-building machine further includes a truss beam, which is sequentially inserted along the transverse direction into the main truss units that are spaced apart along the transverse direction; the truss beam is located below the rear upper crossbeam, and a reinforcing rib structure is provided between the truss beam and the rear upper crossbeam.
[0012] In one embodiment, the bottom basket has guardrails extending to the top of the beam on three adjacent sides to form an all-around protective platform, and the all-around protective platform is equipped with a ladder.
[0013] The bridge-building machine with upper-bearing mobile formwork provided in this application sets the main truss into multiple main truss units in the form of a frame structure. This increases the space on both sides of the main truss, making it easier to set front C-shaped hooks and middle C-shaped hooks at both ends of the front and rear upper crossbeams suspended on the main truss units to support the outer formwork system through the outer guide beams. This effectively simplifies the structure of the main truss and the outer formwork support system, thereby effectively simplifying the structure of the upper-bearing mobile formwork bridge-building machine and reducing the space occupied. By suspending the inner guide beams under the beam to support the inner formwork system, the structure of the inner formwork support system can be effectively simplified. The upper formwork of the outer formwork in the outer formwork system adopts a height-adjustable split structure, which greatly improves the applicability of the outer formwork system to bridge construction at different heights. A full-round protective platform is set on the outer periphery of the bottom basket, and an elevator is set in the full-round protective platform, which can greatly improve the convenience and safety of construction.

[0031] like Figures 2 to 6 As shown in the embodiment of this application, the upper-bearing mobile formwork bridge-building machine includes a main truss 10, a bottom basket 20, an outer formwork system 80, and an outer guide beam 41. The main truss 10 includes at least two sets of main truss units 12 sequentially arranged on the top of the beam 101 along the bridge direction. The main truss unit 12 is a frame structure. Specifically, the main truss unit 12 is a quadrilateral plate-like structure formed by sequentially connecting a straight side and three oblique sides. The quadrilateral plate-like structure is provided with hollow weight-reducing holes 125. The bottom of the main truss unit 12 is a planar structure, and the bottom of the main truss unit 12 is slidably arranged on the top of the beam 101 along the bridge direction. The two ends of the main truss unit 12 are respectively provided with a first hanging part 121 and a third hanging part 123, and the middle of the main truss unit 12 is provided with a second hanging part 122. The third hanging part 123 of the two adjacent main truss units 12 between the two main truss 10 at both ends is arranged adjacently to form a V-shaped gap 124 between the two adjacent main truss units 12; the front upper crossbeam 21 and the rear upper crossbeam 23 of the bottom basket 20 are respectively detachably hung on the first hanging part 121 and the second hanging part 122 of the main truss unit 12 near the end of the beam 101, and the third hanging part 123 is detachably connected to the beam 101. The front upper crossbeam 21 and the rear upper crossbeam 23 are respectively provided with front C-shaped hooks 31 and middle C-shaped hooks 32 at opposite ends along the transverse direction of the bridge; the outer guide beam 41 is spaced along the transverse direction on the hook parts of the front C-shaped hooks 31 and the middle C-shaped hooks 32, and the outer guide beam 41 is arranged along the longitudinal direction of the bridge. The outer formwork system 80 is slidably arranged on the outer guide beam 41 along the transverse direction of the bridge.
[0032] like Figure 2 As shown, in one embodiment, the sloping side of the top of the quadrilateral plate-like structure is inclined downwards; the two ends of the quadrilateral plate-like structure are connected to the first hanging part 121 and the third hanging part 123 respectively to form a duckbill-like structure. Obviously, the main truss unit 12 of the above structure greatly improves its rigidity while minimizing weight. Specifically, the main truss unit 12 is formed by welding sheet metal, and hollow weight-reduction holes 125 and truss beam reserved holes 126 are cut on the main plate.
[0033] like Figure 10 and Figure 11As shown, in one embodiment, the outer mold system 80 includes an outer mold platform 81, and an upper outer mold template 82 and a lower outer mold template 83 connected sequentially from top to bottom along the height direction of the beam 101; wherein, the upper outer mold template 82 includes a first part 821 and a second part 823; the first part 821 and the second part 823 are slidably connected along the height direction of the beam 101; the outer mold platform 81 is disposed on top of the lower outer mold template 83, the upper outer mold template 82 is movably disposed on the outer mold platform 81 along the transverse direction of the bridge, and the upper outer mold template 82 and the lower outer mold template 83 are detachably overlapped on the beam 101; the outer mold platform 81 is slidably disposed on the outer guide beam 41 along the transverse direction of the bridge.
[0034] like Figure 11 As shown, in one embodiment, the top of the outer formwork platform 81 is provided with a telescopic component 83 connected to the bottom of the first part 821. The telescopic component 83 is used to drive the first part 821 to slide relative to the second part 823 along the height direction of the beam 101. Specifically, the telescopic component 83 can be any one of a hydraulic cylinder, an electric cylinder, a pneumatic cylinder, a screw mechanism, and an electric push rod. By setting the upper template 82 of the outer formwork to be telescopic, it is easy to adjust the height of the upper template 82 of the outer formwork, thereby greatly improving the applicability of the outer formwork system to the construction of beams of different heights.
[0035] In one embodiment, the outer formwork system 80 further includes a support platform 84 disposed on the outer formwork platform 81. A telescopic component 83 is disposed on the top of the support platform 84 along the height direction of the beam. A second part 823 is connected to the side of the support platform 84 near the beam 101. A traveling mechanism 85 is disposed at the bottom of the support platform 84 and is disposed on the outer formwork platform 81. The traveling mechanism 85 is used to drive the support platform 84 to move along the transverse direction of the bridge. Specifically, by setting the support platform 84 and the traveling mechanism 85 to support the upper template 82 of the outer formwork and the telescopic component 83, the height and position of the upper template 82 of the outer formwork along the transverse direction can be adjusted very conveniently and reliably.
[0036] The upper-bearing mobile formwork bridge-building machine of this application embodiment sets the main truss 10 into multiple main truss units 12 in the form of a frame structure. This increases the space on both sides of the main truss 10, facilitating the installation of front C-shaped hooks 31 and middle C-shaped hooks 32 at both ends of the front upper crossbeam 21 and rear upper crossbeam 23 suspended on the main truss unit 10. These hooks, along with at least two sets of outer guide beams 41, jointly support the outer formwork system, greatly simplifying the structure of the main truss 10 and the outer formwork support system. This effectively simplifies the structure of the upper-bearing mobile formwork bridge-building machine and reduces the space occupied, ensuring the stability and reliability of the overall structure and construction process of the bridge-building machine. The upper template 82 of the outer formwork can be slidably adjusted in the transverse direction, enabling automatic opening and closing of the toothed block template on the outer side of the web. When there are no toothed blocks on the outer side of the bridge web, such as... Figure 5 As shown, install the bridge-building machine template and complete the pouring; when there are toothed blocks on the outer side of the bridge web, as... Figure 10 , Figure 11 As shown, adjust the position of the upper template 82 of the outer mold so that the upper template 82 of the outer mold is positioned away from the web of the tooth block. Cut the wooden mold and assemble it according to the shape of the tooth block to complete the overall casting.
[0037] like Figure 7 As shown, in one embodiment, the bridge-building machine further includes a truss beam 43, which is sequentially inserted through truss beam pre-reserved holes 126 on the main truss units 12 arranged at intervals along the transverse direction of the bridge. The truss beam 43 is located below the rear upper crossbeam 23, and a reinforcing rib structure 45 is provided between the truss beam 43 and the rear upper crossbeam 23. Specifically, the main truss units 12 at the top of the beam 101 are fixedly connected to each other through the truss beam 43, which makes the rear upper crossbeam 23 anchored to the top of the main truss unit 12 more resilient to stress. By adding a diagonal reinforcing rib structure 45 between the rear upper crossbeam 23 and the truss beam 43, the stress-bearing capacity of the rear upper crossbeam 23 and the main truss unit 12 can be further improved.
[0038] like Figures 4 to 6 As shown, in one embodiment, the bridge-building machine further includes an inner guide beam 42 and an inner formwork system 90. The inner guide beam 42 is detachably connected to the beam 101 and suspended below the beam 101 along the bridge direction. The inner formwork system 90 is slidably mounted on the inner guide beam 42 along the bridge direction. Specifically, the inner formwork system 90 is directly supported by multiple sets of inner guide beams 42 suspended below the beam 101. The inner guide beams 42 can be fixed to the beam 101 by detachable means such as anchoring. The structure is simple, easy to assemble and disassemble, and convenient to construct.
[0039] Specifically, during pouring, such as Figure 4 and Figure 9 As shown, the front C-hook 31 and the front upper crossbeam 21 provide upward tension to the front lower crossbeam 25 of the basket 20, while the middle C-hook 32 and the beam 101 provide upward tension to the rear lower crossbeam 27 of the basket 20. The front C-hook 31 and the middle C-hook 32 suspend the outer guide beam 41, providing it with upward support. The front upper crossbeam 21 and the beam 101 suspend the inner outer guide beam 41 and the inner guide beam 42, providing them with upward tension. When moving forward, the anchorage to the beam 101 is removed, and the main truss system moves forward along the extension direction of the track. The guide system, basket 20, and formwork system move forward and are re-anchored. When retracting, as... Figure 3 and Figure 8 As shown, the front C-shaped hook 31 suspends the front lower crossbeam 25 of the base basket 20, and the middle C-shaped hook 32 suspends the rear lower crossbeam 27 of the base basket 20, causing the bridge-building machine to move backward as a whole.
[0040] like Figure 12As shown, in one embodiment, the top of the main truss 10 is provided with a top protective platform 14, and the top protective platform 14 is surrounded by protective railings 102; the three adjacent sides of the bottom basket 20 are provided with protective railings 102 extending to the top of the beam 101 to form an all-round protective platform, and a ladder 103 is provided inside the all-round protective platform. Preferably, the ladder 103 can also be an elevator to facilitate access to different levels of the platform. The all-round protective platform and the top protective platform 14 can ensure construction safety in all directions.
[0041] As can be seen from the above embodiments, the upper-bearing mobile formwork bridge-building machine involved in this application can increase the space on both sides of the main truss, which facilitates the setting of front C-shaped hooks and middle C-shaped hooks at both ends of the front upper crossbeam and the rear upper crossbeam suspended on the main truss unit to support the outer formwork system through the outer guide beam. Therefore, it can effectively simplify the structure of the main truss and the outer formwork support system, thereby effectively simplifying the structure of the upper-bearing mobile formwork bridge-building machine and reducing the space occupied.
[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily obtained by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
