[0002] As continuous beam bridges develop towards larger spans and multiple spans, the cantilevered cast-in-place beam construction method has been widely used because it fully utilizes the strong ability of prestressed concrete to withstand negative bending moments, greatly improves the spanning capacity of beam bridges, and does not affect navigation or driving under the bridge during construction. It has demonstrated its strong vitality. When constructing the continuous beam joint section, the rigid arm side piers and pier top beam sections are first constructed at the same time, so that the side piers and the top beam section are consolidated into a whole, and then the remaining beam sections are cast in situ.

[0003] In the conventional joint construction of continuous beams in the prior art, a sling is generally used to connect the bottom formwork platform of the hanging basket as a construction platform. However, the sling is made of steel wire rope or synthetic fiber, etc., and is soft. The hanging basket platform is prone to shaking during construction, posing a great safety hazard.

[0016] By adopting the above technical solution, when the second motor is started to drive the first screw rod to rotate, the two sliders sleeved on the first screw rod can move toward or away from each other, thereby realizing the adjustment of the positions of the two sleeves located on the same side of the base plate, so that the spacing of the sleeves arranged along the width direction of the bridge on the base plate can be adaptively adjusted according to the width of the bridge, so as to facilitate the top block to press against the bottom surface of the bridge to perform stability maintenance work on the base plate and the bottom mold beam.

[0029] The present invention discloses a movable continuous beam joint section construction device, such as Figure 1 and Figure 2 As shown, it includes a vehicle body 1, a cantilever frame 11, a bottom mold beam frame 2 and a bottom plate 21. The cantilever frame 11 is detachably mounted on the top surface of the vehicle body 1. A pair of trusses 12 arranged along the width direction of the bridge are horizontally fixedly connected to the top surface of the cantilever frame 11. A rope mechanism 3 is arranged at the top surface of each truss 12 near both ends. The bottom mold beam frame 2 is horizontally suspended at the bottom of the bridge through four rope mechanisms 3 arranged on the two trusses 12. The bottom plate 21 is detachably mounted on the top surface of the bottom mold beam frame 2. A pair of concave seats 26 are fixedly connected to the top surface of the bottom plate 21. The two concave seats 26 are respectively located on the top surface of the bottom plate 21 near the two outer side walls of the bridge. A vertically arranged protective plate 27 can be detachably installed in each concave seat 26.

[0030] When carrying out bridge closure construction, the mobile vehicle body 1 drives the cantilever frame 11 to extend to the top of the closure section. In the process of the vehicle body 1 driving the cantilever frame 11 to move, the truss 12 drives the bottom mold beam frame 2 to move through the rope mechanism 3, so that the bottom mold beam frame 2 and the bottom plate 21 move to the bottom of the bridge closure end position, which is convenient for the workers to carry out mold assembly construction on the bottom plate 21. The setting of the protective plate 27 has a protective effect, reduces the possibility of accidental falls of construction workers, and improves construction safety.

[0031] like Figure 1 and Figure 3 As shown, the rope mechanism 3 includes an electric hoist 31, a sling 32 and a lifting ring 33. The electric hoist 31 is installed on the top surface of the truss 12. Each top surface of the truss 12 is rotatably connected to a pair of pulleys 13. The pair of pulleys 13 are respectively located at positions near the two ends of the top surface of the truss 12. One end of the sling 32 is set on the electric hoist 31, and the other end of the sling 32 passes through the pulley 13 and vertically extends to the end of the truss 12 and hangs vertically. The lifting ring 33 is fixedly connected to the end of the sling 32 away from the electric hoist 31. The lifting ring 33 can be sleeved and installed on the bottom mold beam frame 2. The lifting ring 33 is provided with bolts that can realize the detachable installation of the lifting ring 33 and the bottom mold beam frame 2.

[0032] When the bottom formwork beam 2 and the bottom plate 21 move to the bottom of the bridge joint position, the electric hoist 31 is started to drive the sling 32 to reel in or out, so as to adjust the height of the bottom formwork beam 2 and the bottom plate 21, which is convenient for the workers to carry out construction operations. The setting of the lifting ring 33 facilitates the connection and disassembly of the sling 32 and the bottom formwork beam 2.

[0033] like Figure 2 and Figure 4 As shown, a pair of sleeves 4 are vertically installed on the two outer walls of the bottom plate 21 along the width direction of the bridge, and the two sleeves 4 on the same side of the bottom plate 21 are distributed on both sides of the bridge. A rack 5 that vertically penetrates the sleeve 4 is slidably installed on the inner wall of each sleeve 4, and a top block 51 located on the top of the sleeve 4 is fixedly connected to the top of the rack 5, and a rubber pad 511 is fixedly connected to the top surface of the top block 51. The rack 5 is provided with a vertically arranged limit groove 52 on the side wall away from the tooth surface, and a limit block 45 slidably connected to the inner wall of the limit groove 52 is vertically fixed on the inner wall of the sleeve 4 near the limit groove 52. The horizontal cross-section of the limit block 45 and the limit groove 52 are in a dovetail shape that matches each other, and each sleeve 4 is also provided with a driving component 6 that can drive the rack 5 located in the sleeve 4 to slide in the vertical direction.

[0034] When the bottom formwork beam 2 and the bottom plate 21 move to the designated position at the bottom of the joint section of the two bridges, the rack 5 is driven to gradually move upward by starting the driving assembly 6, so that the top block 51 at the top of the rack 5 is pressed against the bottom surface of the bridge to stabilize the bottom formwork beam 2, thereby reducing the possibility of the hoisted bottom formwork beam 2 being affected by external factors and shaking significantly, thereby improving the safety of the workers when performing construction on the bottom plate 21. The provision of the rubber pad 511 increases the friction between the contact part between the top block 51 and the bridge, thereby improving the tightening effect of the top block 51 on the bridge.

[0035] like Figure 2 and Figure 4 As shown, the driving assembly 6 includes a first motor 61 and a gear 62. The first motor 61 is installed on the outer wall of the sleeve 4. The first motor 61 is a brake motor. The output end of the first motor 61 is coaxially fixedly connected to a first rotating shaft 63 that extends horizontally into the sleeve 4. The first rotating shaft 63 rotates with the inner wall of the sleeve 4. The gear 62 is coaxially fixedly connected to the outer wall of the first rotating shaft 63 that extends into the sleeve 4. The gear 62 is meshed with the rack 5.

[0036] Starting the first motor 61 can drive the first rotating shaft 63 and the gear 62 to rotate. Through the meshing cooperation of the gear 62 and the rack 5, the gear 62 can drive the rack 5 to move in the vertical direction, so that the rack 5 can move upward to drive the top block 51 to press against the bottom surface of the bridge to maintain the stability of the bottom formwork beam frame 2, thereby improving the safety factor of construction.

[0037] like Figure 4 and Figure 5 As shown, a pair of reciprocating screws 41 coaxial with the first rotating shaft 63 are rotatably connected on the inner wall of the sleeve 4, and the pair of reciprocating screws 41 are respectively located at the top and bottom of the first rotating shaft 63. A slide plate 42 that is threadedly matched with the reciprocating screws 41 is sleeved on the outer walls of the two reciprocating screws 41. A cleaning brush 43 that contacts the rack 5 is fixedly connected to the side wall of the slide plate 42 close to the rack 5. The side wall of the slide plate 42 away from the cleaning brush 43 is slidably matched with the inner wall of the sleeve 4 away from the rack 5. A pair of transmission components 44 are arranged on the outer wall of the end of the first rotating shaft 63 away from the first motor 61. The two transmission components 44 can make the first rotating shaft 63 The two reciprocating screw rods 41 are driven to rotate respectively, and the transmission assembly 44 includes a first pulley 441, a second pulley 442 and a belt 443. The first pulley 441 is coaxially fixed to the outer wall of the end of the first rotating shaft 63 away from the first motor 61, and the second pulley 442 is coaxially fixed to the outer wall of the end of the reciprocating screw rod 41 away from the first motor 61. The belt 443 is tensioned and sleeved on the outside of the first pulley 441 and the second pulley 442. The belt 443 links the first pulley 441 and the second pulley 442. The first pulley 441, the second pulley 442 and the belt 443 are all located on the outside of the sleeve 4 away from the first motor 61.

[0038] In the process of the first motor 61 driving the first rotating shaft 63 and the gear 62 to rotate, the first rotating shaft 63 drives the reciprocating screw 41 to rotate through the cooperation of the first pulley 441, the second pulley 442 and the belt 443, so that the slide plate 42 drives the cleaning brush 43 to reciprocate along the axial direction of the reciprocating screw 41, prompting the cleaning brush 43 to clean the rack 5, thereby reducing the possibility of impurities adhering to the rack 5, improving the stability of the meshing work of the rack 5 and the gear 62, reducing the wear of the gear 62 and the rack 5, and increasing their service life.

[0039] like Figure 2 and Figure 6 As shown, the bottom plate 21 is provided with slide grooves 22 on the two outer side walls along the width of the bridge, and a pair of second motors 23 are installed on the outer side wall of the bottom plate 21 near the ends of the two slide grooves 22. The second motor 23 is a brake motor, and the output ends of the two second motors 23 are coaxially fixed with first screw rods 24. The two first screw rods 24 extend into the two slide grooves 22 respectively and rotate with the inner walls of the two slide grooves 22. A pair of sliders 25 that are threadedly matched with the first screw rod 24 are sleeved on the outer side wall of each first screw rod 24. The two sliders 25 are slidably matched with the inner wall of the slide groove 22. The threads on the first screw rod 24 that match the two sliders 25 are symmetrically arranged, and the four sleeves 4 on the outer side wall of the bottom plate 21 are respectively fixedly connected to the side walls of the four sliders 25 in a one-to-one correspondence.

[0040] When the second motor 23 is started to drive the first screw rod 24 to rotate, the two sliders 25 on the first screw rod 24 will move toward or away from each other along the axial direction of the first screw rod 24, so that the distance between the two sleeves 4 arranged along the width direction of the bridge on the bottom plate 21 can be adaptively adjusted according to the width of the bridge, so as to better maintain the stability of the bottom mold beam 2 and the bottom plate 21.

[0041] A movable continuous beam joint section construction mold, such as Figure 1 and Figure 7 As shown, it includes a bottom template 7 and a pair of side templates 71. The bottom template 7 is anchored and installed on the top surface of the bridge. The pair of side templates 71 are detachably installed on the two outer walls of the bottom template 7. The two side templates 71 can be anchored to the two side walls of the bottom of the bridge respectively. The top surface of the bottom plate 21 is provided with a plurality of support blocks 8 located at the bottom of the bottom template 7. The top surface of the support block 8 is in contact with the bottom surface of the bottom template 7. The top surface of the bottom plate 21 can also be detachably installed with a pair of side support brackets 9. The pair of side support brackets 9 are respectively connected to the outside of the two side templates 71, and the two side support brackets 9 are respectively detachably connected to the outer sides of the two side templates 71.

[0042] The mold structure formed by the combination of the bottom template 7 and the two side templates 71 has the advantage of being easy to carry and transport, which is convenient for the staff to quickly assemble and disassemble the mold. The support block 8 and the side support frame arranged on the bottom plate 21 can be used to support the bottom template 7 and the side template 71 respectively, thereby improving the stability of the mold after assembly.

Under the meshing cooperation of the gear 62 and the rack 5, the gear 62 drives the rack 5 to move upward in the vertical direction, so that the top block 51 set on the top of the rack 5 is pressed against the bottom surface of the bridge to stabilize the bottom formwork beam frame 2 and the bottom plate 21, reduce the possibility of the bottom formwork beam frame 2 and the bottom plate 21 being shaken to a large extent by external factors, and improve the safety of the workers when performing construction on the bottom plate 21; In the process of the first motor 61 driving the first rotating shaft 63 and the gear 62 to rotate, the first rotating shaft 63 drives the reciprocating screw 41 to rotate through the transmission assembly 44, so that the slide plate 42 can drive the cleaning brush 43 to reciprocate along the axial direction of the reciprocating screw 41, so that the cleaning brush 43 can clean the rack 5, reduce the possibility of impurities adhering to the rack 5, improve the stability of the meshing work between the rack 5 and the gear 62, reduce the wear of the gear 62 and the rack 5, and increase their service life.
