Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a curing system and mobile formwork for cast-in-place box girders. Background Technology

[0002] Mobile formwork is a type of construction machinery that uses its own formwork and supports piers or abutments to cast concrete for bridges on-site. Concrete curing plays a crucial role in the quality of cast-in-place box girders. Currently, the main method involves installing vertical sprinklers on the mobile formwork atop the box girder for spray curing. However, the spraying range of vertical sprinklers is limited, and the spray volume differs significantly between the center and the outer edge, resulting in uneven curing. This often leads to inadequate curing of the concrete in the cast-in-place box girder by the mobile formwork, which can negatively impact the quality of the box girder and pose safety hazards. Utility Model Content

[0003] The first aspect of this utility model provides a curing system for cast-in-place box girders to solve the defects of inadequate curing in the prior art. By setting multiple rotating nozzles in a fixed spraying device and making them swing and spray the upper surface of the un-demolded box girder from the side, the curing blind spots can be effectively reduced, ensuring that every corner of the surface of the un-demolded box girder is fully sprayed, thus avoiding the problem of inadequate concrete curing.

[0004] The second aspect of this utility model provides a movable mold frame.

[0005] The present invention provides a curing system for cast-in-place box girders, used for spray curing of box girders, including both demolded and undemolded box girders. The curing system for cast-in-place box girders includes:

[0006] Mobile spraying equipment is used for spraying and curing demolded box girders;

[0007] A fixed spraying device includes a water source, a first spraying pipeline, and multiple rotating nozzles. One end of the first spraying pipeline is connected to the water source, and the other end is connected to the rotating nozzles. The rotating nozzles are used to perform oscillating spraying on the upper surface of the undemolded box girder from the side.

[0008] According to the curing system for cast-in-place box girders provided by this utility model, the first spray pipe is arranged in a rectangular structure, the rotating nozzles are arranged at intervals along the rectangular structure, and the shape of the rectangular structure matches the shape of the undemolded box girder.

[0014] According to the curing system for cast-in-place box girders provided by this utility model, the spraying component includes:

[0015] A boom is provided on at least one side of the water storage trolley, and the shape of the boom is adapted to the outer contour of the demolded box girder;

[0016] The second spray pipe is installed along the boom and connected to the water storage trolley;

[0017] Multiple nozzles are spaced apart along the boom and connected to the second spray pipeline.

[0018] According to the curing system for cast-in-place box girders provided by this utility model, there are two mobile spraying devices, which are symmetrically arranged along the center line of the demolded box girder. The spraying component of each set of mobile spraying devices is only located on the side of the water storage trolley away from the center line of the demolded box girder.

[0023] The cast-in-place box girder curing system provided by this utility model, by setting up a mobile spraying device and a fixed spraying device, can carry out targeted spraying curing on both demolded and non-demolded box girders, achieving comprehensive and uniform spraying curing. This ensures that all parts of the cast-in-place box girder receive sufficient curing and maintains suitable moisture conditions during the hardening process, thereby improving the strength and durability of the box girder.

[0024] Compared to the vertical spraying in existing technologies, this invention sets up multiple rotating nozzles in a fixed spraying device, which then perform oscillating spraying on the upper surface of the un-demolded box girder from the side. This effectively reduces blind spots in curing, ensures that every corner of the un-demolded box girder surface is adequately sprayed, improves curing quality, guarantees spray uniformity, avoids problems of inadequate concrete curing, and thus improves the quality of the box girder structure and reduces safety hazards.

[0036] Figure 1 This is a schematic diagram of the installation of the curing system for cast-in-place box girders provided in an embodiment of this utility model from one perspective; Figure 2 This is an installation schematic diagram of the curing system for cast-in-place box girders provided in this embodiment of the utility model from another perspective; Figure 3 yes Figure 1A schematic diagram of the cross-sectional structure at point AA along the middle.

[0037] See Figures 1 to 3 The first aspect of this utility model provides a curing system for cast-in-place beams. This system is used for spray curing cast-in-place box girders, which include demolded box girders 10 and undemolded box girders 20. The undemolded box girder 20 refers to a box girder still encased in a moving formwork, as shown in area A of the figure. The demolded box girder 10 can be referred to... Figure 1 For details regarding the box girder at point B, specifically the demolded box girder 10 and the undemolded box girder 20, please refer to existing technologies; these details will not be repeated here.

[0038] The curing system for cast-in-place beams includes a mobile spraying device 100 and a fixed spraying device 200. The mobile spraying device 100 is used to spray and cure the demolded box beam 10; the fixed spraying device 200 is used to spray and cure the undemolded box beam 20. The fixed spraying device 200 includes a water source 210, a first spraying pipe 220 and multiple rotating nozzles 230. One end of the first spraying pipe 220 is connected to the water source 210 and the other end is connected to the rotating nozzles 230. The rotating nozzles 230 are located above the undemolded box beam 20 and to the side of the undemolded box beam 20. The rotating nozzles 230 are used to perform oscillating spraying on the upper surface of the undemolded box beam 20 from the side of the undemolded box beam 20.

[0039] See Figures 1 to 3 It is understood that the cast-in-place box girder curing system provided in this embodiment of the present invention, by setting up a mobile spraying device 100 and a fixed spraying device 200, can carry out targeted spraying curing on the demolded box girder 10 and the undemolded box girder 20 respectively, so as to achieve comprehensive and uniform spraying curing, ensuring that all parts of the cast-in-place box girder can be fully cured, and ensuring that the cast-in-place box girder maintains suitable moisture conditions during the hardening process, thereby improving the strength and durability of the box girder.

[0040] Compared to the vertical spraying in the prior art, this embodiment of the utility model sets up multiple rotating nozzles 230 in the fixed spraying device 200, and makes them swing to spray the upper surface of the undemolded box girder 20 from the side. In this way, the curing blind spots can be effectively reduced, ensuring that every corner of the surface of the undemolded box girder 20 is fully sprayed, improving the curing quality, ensuring the uniformity of spraying, avoiding the problem of inadequate concrete curing, and thus improving the quality of the box girder and reducing safety hazards.

[0041] Continue reading Figure 2 In an optional embodiment of this utility model, the rotating nozzles 230 are spaced apart along a rectangular structure, the shape of which matches the shape of the undemolded box girder 20. Figure 2For example, six rotating nozzles 230 are respectively set at the diagonal and center of the long side of the rectangular structure. The rotating coverage areas of any two adjacent rotating nozzles 230 are adjacent and overlap each other. The sum of the rotating coverage areas of the six rotating nozzles 230 is greater than or equal to the area of ​​the rectangular structure. In other words, the sum of the rotating coverage areas of the six rotating nozzles 230 is greater than or equal to the upper surface area of ​​the undemolded box girder 20.

[0042] See Figure 2 It is understandable that by setting up a rectangular structure that matches the shape of the undemolded box girder 20, and setting multiple rotating nozzles 230 on the rectangular structure, when the rotating nozzles 230 are in operation, the spraying area of ​​the rotating nozzles 230 can be uniformly overlapped with the upper surface of the undemolded box girder 20. This design helps to ensure the uniformity and coverage of the spraying, avoids some areas being over-sprayed while other areas are under-sprayed, and can also improve the accuracy and efficiency of spraying maintenance, reduce water waste, and conform to the concept of green construction.

[0043] Continue reading Figure 2 and Figure 3 In an optional embodiment of this utility model, the curing system for cast-in-place box girder also includes a control system. Correspondingly, the water source 210 includes a pressurized water source. The mobile spraying device 100, the pressurized water source 210, and the rotating nozzle 230 are electrically connected to the control system. The control system is used to control the operation of the mobile spraying device 100. The control system is also used to control the operation of the pressurized water source and the rotating nozzle 230.

[0044] Specifically, control commands can be preset in the control system, such as the oscillation speed of the nozzle, the spray volume of the nozzle, and the water pressure of the pressurized water source. During actual operation, the pressurized water source can operate according to the predetermined maintenance process according to the preset command program in the control system, providing a stable and continuous high-pressure water flow to the rotating nozzle 230. Correspondingly, the rotating nozzle 230 can also operate according to the predetermined maintenance process according to the preset rotation trajectory and oscillation speed in the control system, thereby realizing oscillating spraying.

[0045] In an optional embodiment of this utility model, the control system can also be directly controlled by on-site construction personnel. Specifically, it can be adapted to the actual situation.

[0046] It is understood that in the cast-in-place box girder maintenance system provided by this embodiment of the invention, by setting up a control system and a pressurized water source, the control system acts as the central hub of the entire maintenance system. Through electrical connections, it works closely in coordination with the water source 210 (especially the pressurized water source), the mobile spraying device 100, and the rotating nozzle 230. This means that manual adjustment of the operating parameters of each device, such as water pressure, spraying speed, and movement path, is no longer required. Instead, the control system automatically completes these adjustments according to a preset program. This highly integrated automated control not only improves work efficiency but also reduces uneven maintenance or resource waste caused by human error. From an automation perspective, the cast-in-place box girder maintenance system, with the introduction of the control system, achieves full automation of the spraying maintenance process. This significantly improves maintenance efficiency and accuracy while reducing the complexity and risk of manual operation, providing a more efficient and intelligent maintenance solution for bridge and road construction.

[0047] In an optional embodiment of this invention, an intelligent identification module can be set in the control system. This allows the system to automatically adjust the water pressure according to the needs of the current maintenance task, enabling automated control of the pressurized water source. For example, when dealing with box girders of different materials or at different maintenance stages, the control system can intelligently identify and adjust to the most suitable water pressure, ensuring that the water mist can penetrate deeply without excessive scouring, thereby achieving the best maintenance effect.

[0048] In an optional embodiment of this invention, a navigation system and sensors can be incorporated into the control system. This allows the control system to automatically plan and execute the spraying path based on the actual position and dimensions of the box girder, relying on the built-in navigation system and sensors. This precise automatic positioning and movement capability ensures that the surface of the demolded box girder 10 receives uniform and sufficient spraying curing.

[0049] In an optional embodiment of this invention, a fault detection module and an alarm function module can be set in the control system. This way, once a component in the system malfunctions or becomes abnormal, the control system will immediately activate the alarm program, promptly alerting operators to handle the issue through audible and visual signals or remote notifications. This automated fault detection and alarm mechanism effectively reduces the risk of maintenance interruptions due to equipment failure, ensuring the continuity and stability of maintenance operations.

[0050] Figure 4 yes Figure 1 A schematic diagram of the cross-sectional structure at the middle edge BB.

[0051] In an optional embodiment of this utility model, the mobile spraying device 100 includes a track 110, a water storage trolley 120, and a spraying component 130. The track 110 is disposed on the upper surface of the demolded box girder 10, the water storage trolley 120 is disposed on the track 110 and slides in cooperation with the track 110, and the water storage trolley 120 is adapted to reciprocate along the track 110; the spraying component 130 is disposed on at least one side of the water storage trolley 120, and the shape of the spraying component 130 is adapted to the outer contour of the demolded box girder 10.

[0052] See Figure 1 and Figure 4 It is understandable that by setting a spraying component 130 that is adapted to the outer contour of the demolded box girder 10, the spraying accuracy can be improved during the curing process of the demolded box girder 10. This ensures that the water mist can be evenly covered on all surfaces of the demolded box girder 10, avoiding water waste and uneven spraying. Based on the cooperation with the track 110 and the water storage trolley 120, the spraying component 130 can achieve comprehensive spraying curing of the entire demolded box girder 10, ensuring the curing quality of the cast-in-place box girder curing system for the undemolded box girder 20.

[0053] Continue reading Figure 4 In an optional embodiment of this utility model, the spraying component 130 includes a boom 131, a second spraying pipe, and multiple nozzles 133. The boom 131 is disposed on at least one side of the water storage trolley 120, and the shape of the boom 131 is adapted to the outer contour of the demolded box beam 10. Specifically, the boom 131 includes a straight section and a curved section. The straight section is used to connect with the water storage trolley 120, and the bending direction of the curved section is adapted to the outer contour of the undemolded box beam 20. The second spraying pipe is disposed along the boom 131 and connected to the water storage trolley 120. The second spraying pipe can be tied to the boom 131 with cable ties. When the boom 131 is a pipe, the second spraying pipe can also be disposed in the inner cavity of the pipe. Multiple nozzles 133 are disposed at intervals along the boom 131 and connected to the second spraying pipe. The spray range of any two adjacent nozzles 133 overlaps with each other to ensure that the water mist fully covers the undemolded box beam 20.

[0054] It is understandable that separating the boom 131 and the second spray pipe can facilitate the manufacturing and design of the spray component 130, reduce the manufacturing difficulty of the boom 131, and ensure that the functionality of the other part is not affected when one part of the boom 131 and the second spray pipe fails, thus reducing the maintenance difficulty of the spray component 130.

[0055] Continue reading Figure 4In an optional embodiment of this utility model, two mobile spraying devices 100 are provided, symmetrically arranged along the centerline of the demolded box girder 10. The spraying component 130 of each set of mobile spraying devices 100 is only located on the side of the water storage trolley 120 away from the centerline of the demolded box girder 10. This arrangement allows both mobile spraying devices 100 to work simultaneously during spraying, significantly shortening the curing time. Furthermore, the space between the two mobile spraying devices 100 can serve as a walking space for the operator, avoiding interference between the mobile spraying devices 100 and the operator's walking path, thus preventing restrictions on the operator's work and providing convenience for the operator.

[0056] Continue reading Figure 4 In an optional embodiment of this utility model, the spraying component 130 further includes a top spray nozzle 134. The top spray nozzle 134 is located at the top of the boom 131 and connected to the second spraying pipeline. The top spray nozzle 134 is positioned towards the centerline of the demolded box beam 10. It can be understood that by setting the top spray nozzle 134, spraying and curing of the upper surface of the demolded box beam 10 can be ensured, and the comprehensiveness of the cast-in-place beam curing system can be further improved.

[0057] Continue reading Figure 4 In an optional embodiment of this utility model, the spraying component 130 further includes a counterweight 135, which is suspended from the lower end of the boom 131. It is understood that during spraying, the boom 131 and nozzle 133 may experience impact forces due to the water flow, causing the spraying component 130 to sway or shift. The presence of the counterweight 135, through its gravity, effectively counteracts these impact forces, allowing the spraying component 130 to maintain a relatively stable position, thereby ensuring the accuracy and uniformity of the spraying.

[0058] Secondly, the counterweight 135 also helps to balance the center of gravity of the spray component 130. By reasonably setting the weight and position of the counterweight 135, the center of gravity of the spray component 130 can be made closer to the center line of the track 110, thereby reducing the extra energy consumption and wear caused by the center of gravity shift during the spraying process, and improving the operating efficiency and life of the device.

[0059] In addition, the addition of counterweight 135 enhances the wind resistance of the spray component 130. In outdoor environments, wind is an important factor. If the spray component 130 is not stable enough, it is easy to sway or tilt under strong winds, which will affect the spraying effect. The presence of counterweight 135 effectively improves the wind resistance of the spray component 130 by increasing its weight and stability, so that the spray component 130 can maintain a stable spraying effect under various weather conditions.

[0060] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the mobile spraying device 100 further includes a water tank 140, which is located at the end of the track 110. The water tank 140 is adapted to the water inlet of the water storage trolley 120. The water tank 140 is used for automatic water filling of the water filling trolley. The water tank 140 and the water storage trolley 120 can be connected to the aforementioned control system to realize the automatic water filling of the water storage trolley 120.

[0061] Understandably, the introduction of water tank 140 greatly simplifies the water replenishment process of water storage trolley 120. In traditional maintenance systems, water storage trolley 120 needs to frequently return to a fixed location for manual water replenishment during spraying operations. This not only consumes a lot of time and manpower but may also lead to interruptions in spraying operations due to untimely water replenishment, affecting the maintenance effect. However, the setting of water tank 140 allows water storage trolley 120 to operate continuously on track 110 without interrupting the spraying process to return for water replenishment, thereby greatly improving the continuity and efficiency of maintenance operations.

[0062] Secondly, the automatic water filling design between the water tank 140 and the water storage trolley 120 realizes the automation and intelligence of the water replenishment process. When the water level in the water storage trolley 120 drops to a certain level, the control system will automatically trigger the water replenishment mechanism to guide the water storage trolley 120 to the water tank 140 for water replenishment. This process does not require manual intervention, reducing human error and inconvenience, and improving the stability and reliability of the system.

[0063] See Figure 1 and Figure 4 In an optional embodiment of this utility model, the fixed spraying device 200 further includes an in-box spraying pipeline, which is connected to a water source 210 and enters the interior space of the demolded box beam 10 through a beam hole channel. The pipeline runs along the bottom of the interior space and is equipped with multiple in-box spray nozzles. The in-box spray nozzles are used to spray and cure the interior space of the demolded box beam 10. Specifically, the existing technology can be consulted for adaptive settings.

[0064] The second aspect of this utility model provides a movable formwork, which includes the curing system for cast-in-place box girders described in any of the foregoing embodiments. It is understood that the movable formwork provided in this embodiment, because it includes the aforementioned curing system for cast-in-place box girders, also has the technical effects of the curing system for cast-in-place box girders described in any of the foregoing embodiments.

[0065] It should be noted that the technical solutions in the various embodiments of this utility model can be combined with each other, but the basis for such combination is that they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this utility model.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
