Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a prefabricated construction operation platform for the front end of a hanging basket in cantilever casting method. Background Technology

[0002] During the construction of cantilever box girders, the installation and removal of end formwork are crucial processes for ensuring the quality of the girder end forming, directly affecting the dimensional accuracy of the cantilever box girder ends. Concrete roughening removes surface laitance from the cantilever box girder ends, increasing the roughness of the interface between new and old concrete, ensuring the structural integrity of the connection. Prestressed tensioning and grouting apply prestress to give the cantilever box girder structure sufficient load-bearing capacity, improving its service life. These three processes are of great significance to construction quality.

[0003] Currently, during the above-mentioned construction processes, workers stand on the horizontal reinforcing bars or vertical ladders on the web of the cantilever box girder at the front end of the sliding beam inside the hanging basket. Because the horizontal reinforcing bars lack a stable support surface and the vertical ladders only provide a single climbing support, workers need to frequently adjust their body posture to complete actions such as formwork assembly / disassembly, roughening, and tensioning / grouting. This makes the operation difficult and inefficient. Furthermore, due to the lack of reliable protection and working platforms, workers are prone to slipping and falling from heights, and falling tools may also cause injury or death to people below, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated construction platform at the front end of the hanging basket for cantilever casting method, which is used to support workers and ensure their construction safety.

[0007] The connecting assembly includes two connecting vertical beams and multiple connecting horizontal beams. The two connecting vertical beams are spaced apart along a first direction, and the multiple connecting horizontal beams are spaced apart along a second direction. Both ends of each connecting horizontal beam are fixedly connected to the two connecting vertical beams. The top end of each connecting vertical beam can be fixedly connected to the front end of the inner sliding beam of the hanging basket. The bottom end of each connecting vertical beam is connected to a lifting component, and the other end of the lifting component abuts against the bottom plate of the hanging basket. The first direction is perpendicular to the second direction.

[0008] The support assembly includes a support plate and a limiting member. Each of the connecting vertical beams is fixedly connected to the limiting member. The support plate has a storage position and a working position. When the support plate is in the storage position, the support plate is attached to the connecting vertical beam. When the support plate is in the working position, the support plate is attached to the limiting member.

[0009] The aforementioned prefabricated construction platform for the hanging basket in the cantilever casting method further includes a telescopic inner tube and a telescopic outer tube. The telescopic outer tube is fixedly connected to the end of the bearing plate away from the limiting member, and the telescopic inner tube is slidably connected to the telescopic outer tube. The other end of the telescopic inner tube can be threaded through and fixed to the structure supporting the cantilever.

[0010] In the aforementioned prefabricated construction platform for the cantilever casting method, the bearing plate is rotatably connected to the limiting member; or, the bearing plate is rotatably connected to the connecting vertical beam.

[0012] The aforementioned prefabricated construction platform for the cantilever casting method includes a rotating shaft. The connecting plate has a first rotating hole, and the bearing plate has a second rotating hole. The rotating shaft can pass through the first rotating hole and the second rotating hole to allow the bearing plate to rotate relative to the connecting plate.

[0013] The aforementioned prefabricated construction platform for the cantilever casting method hanging basket front end has multiple limiting components spaced at intervals along the first direction for each connecting vertical beam, with adjacent limiting components spaced 2-2.5 meters apart.

[0014] In the aforementioned prefabricated construction platform for the cantilever casting method hanging basket, each connecting vertical beam is provided with two triangular limiting members spaced apart along the first direction. The supporting surface of the limiting member extends along a third direction, which is perpendicular to the plane formed by the first direction and the second direction. The supporting surface is used to limit and support the bearing plate.

[0015] The aforementioned prefabricated construction platform for the front end of the hanging basket in the cantilever casting method has a hook-shaped top end that can be attached to the front end of the inner sliding beam of the hanging basket.

[0016] The aforementioned prefabricated construction platform for the front end of the hanging basket in the cantilever casting method includes a lifting component comprising a fixed part, an abutting part, and an adjusting part.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This utility model provides a prefabricated construction platform at the front end of the hanging basket for cantilever casting, which can support workers, ensure their safety, and improve construction efficiency.

[0037] like Figures 1-5As shown, the prefabricated construction platform at the front end of the cantilever casting method hanging basket includes a connecting component 1 and a bearing component 3. The connecting component 1 includes two connecting vertical beams 11 and multiple connecting horizontal beams 12. The two connecting vertical beams 11 are spaced apart along a first direction, and the multiple connecting horizontal beams 12 are spaced apart along a second direction. Both ends of each connecting horizontal beam 12 are fixedly connected to the two connecting vertical beams 11. The top end of each connecting vertical beam 11 can be fixedly connected to the front end 110 of the inner sliding beam of the hanging basket 100. The bottom end of each connecting vertical beam 11 is connected to a lifting component 2, and the other end of the lifting component 2 abuts against the bottom plate 120 of the hanging basket 100. The first direction is perpendicular to the second direction. The bearing component 3 includes a bearing plate 31 and a limiting component 32. Each connecting vertical beam 11 is fixedly connected to the limiting component 32. The bearing plate 31 has a storage position and a working position. When the bearing plate 31 is in the storage position, the bearing plate 31 is attached to the connecting vertical beam 11. When the bearing plate 31 is in the working position, the bearing plate 31 is attached to the limiting component 32. First direction such as Figure 4 As shown in the X direction, the second direction is as follows: Figure 4 Shown in the Y direction.

[0038] The prefabricated construction platform for the cantilever casting method provided by this utility model has its top end fixedly connected to the front end 110 of the inner sliding beam of the hanging basket 100 during use. This securely connects the vertical beam 11 and the hanging basket 100. The bearing plate 31 can be adjusted to a supporting working position, allowing workers to stand on it and reducing the risk of falls. Simultaneously, any workpieces falling will land on the bearing plate 31, preventing injury to personnel below and further improving safety. After each cantilever box girder segment is completed, the bearing plate 31 can be retracted, reducing its space occupation and preventing spatial interference. This ensures the prefabricated construction platform can move forward with the hanging basket 100 without disassembling it, improving work efficiency.

[0039] This embodiment does not specifically limit the number of connecting beams 12. For example, there are two connecting beams 12. The two connecting beams 12 are fixed at intervals between the two connecting vertical beams 11 along the second direction to support the connecting vertical beams 11 and improve the stability of the overall structure.

[0040] In other embodiments, three connecting vertical beams 11 may also be provided to further improve stability.

[0041] To facilitate the connection between the vertical beam 11 and the hanging basket 100, in this embodiment, see... Figure 1 and Figure 4The top of the connecting vertical beam 11 is hook-shaped, allowing it to overlap the front end 110 of the inner sliding beam of the hanging basket 100. During installation, the connecting vertical beam 11 overlaps the front end 110 of the inner sliding beam of the hanging basket 100 to achieve initial positioning and reduce installation difficulty. After positioning, existing bolts can be used to reinforce the connection between the connecting vertical beam 11 and the front end 110 of the inner sliding beam of the hanging basket 100, improving connection stability.

[0042] The lifting component 2 is used to adjust the distance between the base plate 120 of the hanging basket 100 and the connecting vertical beam 11, thereby improving the support stability. The lifting component 2 can be an existing pneumatic cylinder or hydraulic cylinder, and the distance adjustment is achieved by the extension and retraction of the piston rod.

[0043] In this embodiment, see Figure 2 and Figure 3 The lifting component 2 includes a fixing part 21, an abutting part 22, and an adjusting part 23. The fixing part 21 can be fixedly connected to the bottom end of the connecting vertical beam 11. The abutting part 22 is fixedly connected to the bottom end of the adjusting part 23 and is used to abut against the base plate 120. The adjusting part 23 is threadedly connected to the fixing part 21. The threaded connection can be self-locking, which improves the support stability.

[0044] Specifically, the fixing part 21 has threads circumferentially and a threaded hole at its center, allowing it to be threadedly connected to the bottom end of the connecting vertical beam 11 for easy connection. The adjusting part 23 can be a screw that can be threadedly connected to the threaded hole of the fixing part 21. The abutting part 22 can be a circular plate, and it can be fixed to the adjusting part by welding, resulting in easy and strong connection.

[0045] In use, the rotating adjustment part 23 drives the abutment part 22 to move downwards until it abuts against the bottom plate 120 of the hanging basket 100. It should be noted that... (See also...) Figure 1 and Figure 2 The bottom plate 120 of the hanging basket 100 is inclined, so a lifting component 2 needs to be designed to change the distance between the bottom plate 120 of the hanging basket 100 and the connecting vertical beam 11, so as to ensure that the bottom plate 120 of the hanging basket 100 stably supports the connecting vertical beam 11.

[0046] Furthermore, a buffer pad is provided at the end of the contact part 22 away from the adjustment part 23. The buffer pad prevents the contact part 22 from rigidly contacting the bottom plate 120 of the hanging basket 100, thereby reducing impact and preventing damage.

[0047] Specifically, the cushioning pad can be made of existing rubber, and the rubber can be cut to a suitable shape according to the shape of the abutment part 22. The cushioning pad can be glued and fixed to the abutment part 22, making the connection convenient.

[0048] The support plate 31 is used to support the workers. The support plate 31 can be inserted into the connecting vertical beam 11 or rotatably connected to the connecting vertical beam 11. Optionally, the connecting vertical beam 11 has a working groove and a storage groove. When the support plate 31 is inserted into the working groove, the support plate 31 is in the working position; when the support plate 31 is inserted into the storage groove, the support plate 31 is in the storage position.

[0049] Optionally, the support plate 31 is rotatably connected to the limiting member 32; or, the support plate 31 is rotatably connected to the connecting vertical beam 11. The rotatable connection makes it more convenient to adjust the support plate 31 from the working position to the storage position, or from the storage position to the working position.

[0050] Specifically, see Figure 4 and Figure 5 The prefabricated construction platform at the front end of the cantilever casting method also includes a connecting plate 4, which is fixedly connected to the connecting vertical beam 11, and the bearing plate 31 is rotatably connected to the connecting plate 4. The bearing plate 31 is rotatably connected to the connecting plate 4, and the connecting plate 4 can be disassembled separately during maintenance, reducing maintenance costs.

[0051] The support plate 31 can be connected to the connecting plate 4 via a bearing or via a hole shaft. For example, see [link to example]. Figure 4 and Figure 5 The prefabricated construction platform at the front end of the cantilever casting method hanging basket also includes a rotating shaft 5. The connecting plate 4 has a first rotating hole 41, and the bearing plate 31 has a second rotating hole. The rotating shaft 5 can pass through the first rotating hole 41 and the second rotating hole to make the bearing plate 31 rotate relative to the connecting plate 4, which is convenient for processing and assembly.

[0052] During use, the rotating bearing plate 31 rotates away from the connecting vertical beam 11, and the end of the bearing plate 31 away from the connecting vertical beam 11 abuts against the limiting member 32. The limiting member 32 limits and supports the bearing plate 31, preventing it from swaying and ensuring that workers can stand stably on the bearing plate 31. When the rotating bearing plate 31 rotates closer to the connecting vertical beam 11, it can fit snugly against the connecting vertical beam 11, reducing space occupation, avoiding interference, and ensuring that the prefabricated construction platform at the front end of the cantilever casting method can move with the hanging basket 100, improving work efficiency.

[0053] Furthermore, each connecting vertical beam 11 is provided with multiple limiting members 32 at intervals along the first direction. The interval between two adjacent limiting members 32 is 2-2.5 meters. Multiple limiting members 32 can simultaneously limit and support multiple bearing plates 31, providing support positions at different heights. When workers are working at different heights, there is no need to reinstall the bearing plates 31, reducing installation time and improving work efficiency.

[0054] Specifically, the two adjacent limiting components 32 are spaced 2 meters apart.

[0055] Specifically, each connecting vertical beam 11 is provided with two triangular limiting members 32 spaced apart along the first direction. The supporting surface of the limiting member 32 extends along a third direction, which is perpendicular to the plane formed by the first and second directions. The supporting surface is used to limit and support the bearing plate 31. The triangle has stability, which can improve the support effect on the bearing plate 31 and prevent swaying. The third direction is as follows: Figure 4 As shown in the Z direction.

[0056] To further improve support stability, for example, the prefabricated construction platform at the front end of the cantilever casting method hanging basket also includes a telescopic inner tube and a telescopic outer tube. The telescopic outer tube is fixedly connected to the end of the bearing plate 31 away from the limiting member 32, and the telescopic inner tube is slidably connected to the telescopic outer tube. The other end of the telescopic inner tube can be threaded through and fixed to the structure supporting the cantilever box girder. Support structures are provided on both sides of the bearing plate 31. On the one hand, this can prevent the bearing plate 31 from overturning and improve support stability. On the other hand, it can evenly distribute the load and reduce local stress concentration.

[0057] It should be noted that a web is required during the casting of the cantilever box girder. The web is used to withstand the shear force, bending moment, and torque of the cantilever box girder. The main reinforcement of the web structure is used to ensure the load-bearing performance of the web. In this embodiment, the telescopic inner tube can be fixedly connected to the main reinforcement of the web.

[0058] When using the prefabricated construction platform for the cantilever casting method using a hanging basket, the connecting vertical beam 11 is first attached to the front end 110 of the inner sliding beam of the hanging basket 100 and reinforced with bolts. Then, the bearing plate 31 is rotated to the working position, and the telescopic inner tube is slid to fix the telescopic inner tube to the structure supporting the cantilever box girder. Then, the operator stands on the bearing plate 31 to perform the work. For different working heights, the operator can stand on the bearing plate 31 at different heights. Finally, the bearing plate 31 is adjusted to the storage position to facilitate the movement of the prefabricated construction platform for the cantilever casting method using a hanging basket along with the hanging basket 100.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
