Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a construction platform and construction method for converting a continuous beam system. Background Technology

[0002] Currently, prestressed concrete continuous beams are widely used in bridge engineering due to their advantages such as high structural stiffness, small deformation, fewer expansion joints, smooth and comfortable driving, simple and beautiful shape, low maintenance workload, and strong seismic resistance. The construction process for uniform cross-section continuous beams generally adopts a simple-supported-then-continuous construction technique. This involves first supporting the simply supported beam with temporary supports, then installing permanent supports after the entire multi-span simply supported beam is erected or poured, constructing wet joints between spans, tensioning the prestressing in the negative moment zone at the pier top, and applying continuous prestressing. After the grouting of the ducts is completed and the strength meets the requirements, the system conversion construction is carried out. Typically, system conversion construction requires slightly lifting the continuous beam, removing the temporary supports, or using sand-box type temporary supports, and lowering the beam by releasing sand. Regardless of the method, a safe and reliable construction platform must be provided around the pier top.

[0003] In existing technologies, the two most commonly used platform types are ground-mounted supports and pier-top "U"-shaped suspended platforms. However, ground-mounted supports are time-consuming to erect and dismantle, posing significant safety risks during high pier system conversions; pier-top "U"-shaped suspended platforms have poor reliability and are difficult to dismantle. Summary of the Invention

[0004] This invention provides a construction platform and method for the conversion of continuous beam systems, in order to solve the technical problems in related technologies, such as the long time required for the erection and dismantling of ground-mounted scaffolds, the significant safety risks during the conversion of high pier systems, and the poor reliability and difficult dismantling of the "U"-shaped hanging platform on the pier top.

[0005] Firstly, a construction platform for the conversion of continuous beam systems is provided, including: Two operating platforms are symmetrically suspended on both sides of the continuous beam. Each operating platform is also equipped with an anchoring component, which is connected to the continuous beam. Four telescopic frames are provided, with two telescopic frames symmetrically arranged at the bottom of one of the operating tables, and each telescopic frame can slide along the transverse bridge of the operating table. When the two operating platforms are symmetrically suspended on both sides of the continuous beam, each telescopic frame slides along the transverse direction of the operating platform and connects with each other to form a construction platform.

[0006] In some embodiments, each of the operating consoles includes: A top truss, which is provided on the continuous beam along the transverse direction of the bridge; A vertical truss, which is arranged vertically below the top truss; The bottom basket platform is located at the bottom of the vertical truss along the transverse direction of the bridge, and every two telescopic frames are symmetrically arranged on both sides of the bottom basket platform.

[0007] In some embodiments, each of the operating consoles further includes: Multiple lifting lugs are spaced apart at the top of the top truss and the bottom of the bottom basket platform.

[0009] In some embodiments, the bottom of the top truss is also provided with a plurality of traveling wheels, which are used to drive the operating platform to move along the continuous beam bridge deck.

[0010] In some embodiments, a vertical ladder is provided on the inner side of the vertical truss along the vertical direction.

[0011] In some embodiments, the basket platform includes: The second slide rail is located at the bottom of the operating platform along the transverse bridge direction; The second pulley is disposed on the second slide rail and can slide along the length of the second slide rail.

[0012] In some embodiments, each of the telescopic frames is provided with a third slide rail along the transverse bridge direction, and a flatbed trolley is provided on the third slide rail, the flatbed trolley being able to slide along the length direction of the third slide rail.

[0013] Secondly, a construction method for converting a continuous beam system is provided, using the aforementioned construction platform for converting a continuous beam system, including: Two operating platforms were hoisted and suspended on both sides of the continuous beam, and anchoring components were installed to connect each operating platform to the continuous beam. Slide each telescopic frame and connect the four telescopic frames in pairs to form a construction platform; The construction platform was used to carry out the system conversion construction of the continuous beam.

[0014] In some embodiments, the use of a construction platform to perform system conversion construction on the continuous beam includes: Install multiple jacks at the preset positions on the top of the pier, and control the multiple jacks to lift the continuous beam synchronously through the pump station until the top steel plate of the temporary support can be pulled out, and then stop and lock the multiple jacks. The temporary supports were removed one by one, and multiple jacks were unloaded simultaneously, so that the continuous beam could be successfully placed on the permanent supports. Multiple jacks were moved out and hoisted onto the bridge deck of the continuous beam.

[0015] The beneficial effects of the technical solution provided by this invention include: This invention provides a construction platform and method for converting a continuous beam system. The construction platform includes two operating platforms and four telescopic frames. The two operating platforms are symmetrically suspended on both sides of the continuous beam.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a construction platform for the conversion of continuous beam systems, which can solve the technical problems of existing ground-mounted scaffolding which takes a long time to erect and dismantle, poses a great safety risk during the conversion of high pier systems, and has poor reliability and is difficult to dismantle when using the "U"-shaped hanging platform on the pier top.

[0020] Figure 1 This invention provides a construction platform for converting a continuous beam system, comprising: two operating platforms 1 and four telescopic frames 2. The two operating platforms 1 are symmetrically suspended on both sides of a continuous beam 3. Each operating platform 1 is also provided with an anchoring component 11, which is connected to the continuous beam 3. Every two telescopic frames 2 are symmetrically arranged at the bottom of one of the operating platforms 1. Each telescopic frame 2 can slide along the transverse direction of the operating platform 1. When the two operating platforms 1 are symmetrically suspended on both sides of the continuous beam 3, each telescopic frame 2 slides along the transverse direction of the operating platform 1 and is connected in pairs to form a construction platform.

[0021] The construction platform for converting a continuous beam system according to this invention includes two operating platforms and four telescopic frames. The two operating platforms are symmetrically suspended on both sides of the continuous beam, and each operating platform is also equipped with an anchoring component connected to the continuous beam. Two telescopic frames are symmetrically positioned at the bottom of each operating platform, and each telescopic frame can slide along the transverse direction of the operating platform. When the two operating platforms are symmetrically suspended on both sides of the continuous beam, each telescopic frame slides along the transverse direction of the operating platform and connects in pairs to form a construction platform. The two operating platforms and four telescopic frames form a closed construction platform on the sides and bottom of the continuous beam, improving reliability and safety, ensuring the safety of construction personnel. Furthermore, the two operating platforms and four telescopic frames can be directly reused without disassembly or reassembly after each use, facilitating dismantling and transportation, greatly improving construction efficiency, and reducing construction costs.

[0022] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, each of the operating platforms 1 includes: a top truss 12, a vertical truss 13, and a bottom basket platform 14. The top truss 12 is arranged on the continuous beam 3 along the transverse direction of the bridge. The vertical truss 13 is arranged vertically below the top truss 12. The bottom basket platform 14 is arranged at the bottom of the vertical truss 13 along the transverse direction of the bridge. Every two telescopic frames 2 are symmetrically arranged on both sides of one bottom basket platform 14. The top truss 12 serves as the main load-bearing structure of the entire operating platform 1, bearing the load of the entire operating platform 1 and suspending it. Suspended on the bridge deck of the continuous beam 3, the platform forms a rigid frame with the vertical truss 13, improving the overall rigidity of the operating platform 1, replacing the ground support, and avoiding the problems of low rigidity and poor reliability of the "U"-shaped suspended platform; the vertical truss 13 connects the top truss 12 and the bottom basket platform 14, transferring vertical loads, enhancing structural stability, providing stable support, and ensuring the safety of the enclosed work area; the bottom basket platform 14 provides a safe and reliable working surface, replacing the need for additional access channels to traditional platforms.

[0023] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, each operating platform 1 further includes: multiple lifting lugs 15, which are spaced apart at the top of the top truss 12 and the bottom of the bottom basket platform 14. The multiple lifting lugs 15 are used to provide standardized and highly reliable lifting support points. The lifting lugs 15 at the top of the top truss 12 are used to lift the operating platform 1, ensuring the safety of the lifting environment and the reliability of the lifting. The lifting lugs 15 at the bottom of the bottom basket platform 14 are used in conjunction with the chain hoist to assist in the removal of temporary supports.

[0024] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the top truss 12 includes: a first slide rail 121, a first pulley 122, and an electric hoist 123. The first slide rail 121 is located on the top of the operating platform 1 along the transverse direction of the bridge. The first pulley 122 is located on the first slide rail 121 and can slide along the length of the first slide rail 121. The electric hoist 123 is located on the first pulley 122. The first slide rail 121 is located on the top of the top truss 12. The first pulley 122 drives the electric hoist 123 to slide along the length of the first slide rail 121. When the system conversion construction requires the jack 4 to be installed to the preset position on the pier top, the first pulley 122 drives the electric hoist 123 to slide. The electric hoist 123 slides to the right side of the first slide rail 121, which is above the continuous beam 3. The electric hoist 123 is used to suspend the jack 4. The first pulley 122 is slid to move the electric hoist 123 to the left side of the first slide rail 121, and the electric hoist 123 is used to lower the jack 4. When it is necessary to move the jack 4 out and hoist it to the bridge deck of the continuous beam 3, the electric hoist 123 is used to suspend the jack 4. The electric hoist 123 is used to raise the jack 4. Then the first pulley 122 is slid to move the electric hoist 123 to the right side of the first slide rail 121, which is above the continuous beam 3.

[0025] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the top truss 12 is also provided with multiple traveling wheels 124. The multiple traveling wheels 124 are used to drive the operating platform 1 to move along the bridge deck of the continuous beam 3. The top truss 12 is pulled on the bridge deck by a winch, and the multiple traveling wheels 124 can drive the operating platform 1 to move along the bridge deck of the continuous beam 3, so that the operating platform 1 can move along the continuous beam without disassembling the operating platform 1, thus avoiding the time-consuming problem of re-erecting.

[0026] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, a vertical ladder 131 is provided on the inner side of the vertical truss 13 along the vertical direction. The vertical ladder 131 provides a stable vertical passage for construction workers, avoiding the risk of slipping and falling caused by directly climbing the vertical truss 13. Moreover, the vertical ladder 131 is located on the inner side of the vertical truss 13, which further ensures the safety of construction workers.

[0027] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the bottom basket platform 14 includes: a second slide rail 141 and a second pulley 142. The second slide rail 141 is located at the bottom of the operating platform 1 along the transverse direction of the bridge. The second pulley 142 is located on the second slide rail 141 and can slide along the length of the second slide rail 141. The second slide rail 141 is located at the top of the bottom basket platform 14. The second pulley 142 can slide left and right along the length of the second slide rail 141. When the system conversion construction requires the jack 4 to be installed at a preset position on the pier top, the first pulley 122 drives the electric hoist 123 to slide to the right side of the first slide rail 121, that is, above the continuous beam 3. The electric hoist 123 is used to suspend the jack 4. The first pulley 122 is slid to drive the electric hoist 123 to the left side of the first slide rail 121, and the electric hoist 122 is used to suspend the jack 4. The electric hoist 123 lowers the jack 4. The second pulley 142 slides the jack 4 to the left side of the second slide rail 141, below the electric hoist 123. The jack 4 is then transferred from the electric hoist 123 to the second pulley 142. The second pulley 142 then slides the jack 4 to the right side of the second slide rail 141, i.e., the pier top position. When the jack 4 needs to be moved and hoisted onto the bridge deck of the continuous beam 3, the hook on the second pulley 142 is used to suspend the jack 4. The second pulley 142 slides the jack 4 to the left side of the second slide rail 141, below the electric hoist 123, transferring the jack 4 onto the electric hoist 123 for lifting, thus hoisting the jack 4 onto the bridge deck of the continuous beam 3.

[0028] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 and Figure 2As shown, each of the telescopic frames 2 is provided with a third slide rail 21 along the transverse direction of the bridge. A flatbed trolley 22 is provided on the third slide rail 21. The flatbed trolley 22 can slide along the length direction of the third slide rail 21, i.e., the transverse direction of the bridge. Each telescopic frame 2 is located on the side of the pier top. The flatbed trolley 22 is used to transport the jacks 4, replacing manual handling. When the system conversion construction requires the jacks 4 to be installed in a preset position on the pier top, the electric hoist 123 hoists the jacks 4 down and drives them to slide to the right side of the second slide rail 141, i.e., the side of the pier top, through the second pulley 142. Then, the jacks 4 are placed on the flatbed trolley 22, so that the flatbed trolley 22 drives the jacks 4 along the length direction of the third slide rail 21, i.e., the transverse direction of the bridge. The bridge slides to the right to the installation position of the jack 4; when it is necessary to move the jack 4 out and hoist it to the bridge deck of the continuous beam 3, the jack 4 is moved out of the pier top and placed on the flatbed trolley 22, so that the flatbed trolley 22 drives the jack 4 to slide along the length direction of the third slide rail 21, that is, to the left side of the transverse bridge direction, to the position of the second pulley 142, and then the jack 4 on the flatbed trolley 22 is transferred to the second pulley 142. Then, the jack 4 is hoisted to the bridge deck of the continuous beam 3 by sliding the second pulley 142, using the electric hoist 123 to rise, and the first pulley 122 to slide. In addition, each telescopic frame 2 is provided with steel wheels on both sides of its bottom, which can realize the smooth sliding out and retraction of the telescopic frame 2.

[0029] This invention also provides a construction method for converting a continuous beam system, see [link to relevant documentation]. Figure 3 As shown, the construction platform using the aforementioned continuous beam system conversion includes: Two operating platforms 1 are hoisted using a bridge crane and suspended on both sides of the continuous beam 3. Anchoring components 11 are installed to connect each operating platform 1 to the continuous beam 3. Each telescopic frame 2 is slidable, and the ends of the four telescopic frames 2 are connected in pairs using locking bolts to form a construction platform. The construction platform is used to carry out system conversion construction on the continuous beam 3. The two operating platforms and the four telescopic frames form a closed construction platform on the sides and bottom of the continuous beam, which improves reliability and safety, ensures the safety of construction personnel, and the two operating platforms and the four telescopic frames can be directly reused without disassembly or reassembly after each use, which facilitates dismantling and transportation, greatly improves construction efficiency, and reduces construction costs.

[0030] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 2 , Figure 4 and Figure 5As shown, the system conversion construction of the continuous beam 3 using the construction platform includes: installing multiple jacks 4 to the preset positions on the pier top, controlling the multiple jacks 4 to simultaneously lift the continuous beam 3 through the pump station 5 until the top steel plate of the temporary support 6 can be pulled out, and locking the multiple jacks 4; dismantling the temporary support 6 in sequence and unloading the multiple jacks 4 simultaneously, so that the continuous beam 3 can be smoothly placed on the permanent support 7; and moving the multiple jacks 4 out and hoisting them onto the bridge deck of the continuous beam 3.

[0031] Specifically, during the construction of the continuous beam system conversion, the first pulley 122 is used to drive the electric hoist 123 to slide, and the multiple jacks 4 on the bridge deck of the continuous beam 3 are lowered and transported to the bottom basket platform 14. Then, the second pulley 142 is used to suspend the multiple jacks 4 and drive them to slide to the right side of the second slide rail 141, i.e., the side of the pier top. Then, the flatbed trolley 22 drives the multiple jacks 4 to slide to the right along the length of the third slide rail 21 to the installation position of the jacks 4, so that the multiple jacks 4 can be gradually installed to the preset position on the pier top. The pump station 5 is used to control the multiple jacks 4 to synchronously and slowly lift the continuous beam 3 until the top steel plate of the temporary support 6 can be pulled out, and then the mechanical locks of the multiple jacks 4 are locked. Then, the lifting lugs 15 at the bottom of the bottom basket platform 14 are used in conjunction with the guide chain. The hoist sequentially removes the temporary support 6, slowly and synchronously unloading multiple jacks 4, allowing the continuous beam 3 to smoothly fall onto the permanent support 7. Finally, the unloaded multiple jacks 4 are placed on the flatbed trolley 22, which then slides the multiple jacks 4 along the length of the third slide rail 21 to the left to the position of the second pulley 142. The jacks 4 on the flatbed trolley 22 are then transferred to the second pulley 142. The jacks 4 are then hoisted onto the bridge deck of the continuous beam 3 by the sliding of the second pulley 142, the lifting of the electric hoist 123, and the sliding of the first pulley 122. After the system conversion of this pier is completed, a winch is used to pull the top truss 12 on the bridge deck to move the two operating platforms 1 forward to the next pier. The above process is repeated until the system conversion construction of the entire continuous beam is completed.
