Description
TECHNICAL FIELD
[0001] The utility model belongs to cast-in-situ continuous beam maintenance technical field, and mainly relates to a kind of cantilever continuous beam automatic spraying maintenance system. BACKGROUND
[0002] Cantilever continuous beam needs maintenance, mainly based on the following important reasons:
[0003] The strength development of concrete needs suitable temperature and humidity conditions. Maintenance can provide a relatively stable environment for concrete, allowing cement to fully hydrate, thereby promoting the normal growth of concrete strength. In the large structure of cantilever continuous beam, the normal development of concrete strength is crucial for bearing the weight of the structure itself and the load during subsequent construction and use.
[0004] During the drying process of concrete, water will gradually evaporate, causing volume shrinkage. If maintenance is not timely, the surface water of concrete evaporates too quickly, and the internal water cannot be replenished in time, which will cause tensile stress on the surface. When the tensile stress exceeds the tensile strength of concrete, dry shrinkage cracks will occur.
[0005] A large amount of heat is generated during the hydration of cement, causing the internal temperature of concrete to rise. In the large volume concrete structure of cantilever continuous beam, internal heat is not easily dissipated, and the temperature difference between inside and outside is large, which will generate temperature stress. Through maintenance, appropriate temperature control measures such as covering insulation materials can be taken to reduce the temperature difference between inside and outside, reduce temperature stress and prevent the occurrence of temperature cracks.
[0006] Good maintenance can make the microstructure of concrete more dense, reduce pores and cracks, and thus improve the durability indicators such as impermeability and frost resistance of concrete. For the structure of cantilever continuous beam which is exposed to natural environment for a long time, the improvement of durability can prolong its service life and reduce maintenance cost.
[0007] Cantilever continuous beam is a whole structure, and the performance of concrete at each part is related to each other. Through comprehensive and standardized maintenance, the performance of concrete at each part is uniform, so that the structure can work cooperatively when under stress, thereby ensuring the integrity and stability of the whole structure.
[0008] However, the existing cantilever cast-in-situ continuous beam maintenance method is to sprinkle water on the continuous beam, but a large amount of water will fall from the continuous beam to the ground, so that the water cannot be fully used for the maintenance of the continuous beam, causing water waste. UTILITY MODEL CONTENTS
[0009] The utility model provides a kind of cantilever continuous beam automatic spraying maintenance system to solve the problem of water waste caused by cantilever cast-in-situ continuous beam maintenance method in prior art.
[0010] To solve the above problems, the present invention adopts the following technical solution:
[0011] An automatic sprinkler curing system for a cantilever continuous beam includes a truss mounted on the continuous beam, water pipes mounted on the truss, and a water tank connected to the water pipes. The truss includes an outer formwork truss slidably mounted on the outside of the continuous beam and an inner formwork truss slidably mounted on the inside of the continuous beam. The water pipes are equipped with multiple nozzles for sprinkling water. The water pipes are mounted on both the outer and inner formwork trusses so that the water pipes can spray water to cure the outside and inside of the continuous beam.
[0012] The outer formwork truss is equipped with a recovery component located on the lower side of the continuous beam. The recovery component has a recovery trough inside, so that water used to maintain the outer side of the continuous beam falls into the recovery trough.
[0013] A scraper is fixedly mounted on the inner formwork truss. The scraper moves with the inner formwork truss to scrape off the water at the bottom of the inner side of the continuous beam so that the water falls into the recycling tank.
[0014] The opening of the recycling tank has a filter plate for filtering out impurities. The outer formwork truss is equipped with a recycling pipe. One end of the recycling pipe passes through the filter plate and is inserted into the recycling tank. The other end of the recycling pipe is connected to a water tank. A recycling pump is installed on the recycling pipe to draw water from the recycling tank and return it to the water tank.
[0015] It has the following beneficial effects: During the maintenance of continuous beams, the water falling from the continuous beams will fall into the recycling tank. The filter plate filters the water after maintenance, and then the recycling pump will transport the filtered water in the recycling tank back to the water tank, realizing the reuse of maintenance water and reducing water waste.
[0016] Furthermore, the bottom of the recycling tank is a downward-concave arc shape.
[0017] It has the following beneficial effects: the downward-concave arc-shaped bottom of the tank allows the water falling into the recycling tank to collect in the middle, making it easier for the recycling pipe to recycle the water.
[0018] Furthermore, one end of the recycling pipe is located at the lowest point of the bottom of the arc-shaped recycling tank.
[0019] It has the following beneficial effects: the recovery pipe is located at the lowest point, which can fully recover the water in the recovery tank and reduce the water residue in the recovery tank.
[0020] Furthermore, the filter plate can be detachably assembled onto the recycling component, and an annular support seat is provided on the wall of the recycling tank, with the filter plate fixed to the annular support seat by bolts.
[0021] Furthermore, the outer formwork truss includes a left truss for erecting on the left side of the continuous beam and a right truss for erecting on the right side of the continuous beam. The recyclable component is located between the left truss and the right truss. The left truss partially encloses the left wing plate, left wall and lower side of the continuous beam, and the right truss partially includes the right wing plate and right wall of the continuous beam.
[0022] The water pipe includes a first branch pipe, a second branch pipe, and a third branch pipe. The nozzle includes a first nozzle, a second nozzle, and a third nozzle. The first branch pipe is located on the left truss and has multiple first nozzles to spray water on the left wing plate, left side wall, and lower side of the continuous beam. The second branch pipe is located on the inner formwork truss and has multiple second nozzles to spray water on the inner side wall of the continuous beam. The third branch pipe is located on the right truss and has multiple third nozzles to spray water on the right wing plate and right side wall of the continuous beam.
[0023] It has the following beneficial effects: By designing a truss, the first, second, and third branch pipes are all arranged on the truss, and each nozzle sprays water towards the continuous beam for curing. At the same time, the truss is slidably assembled on the continuous beam. When one section of the continuous beam has been cured, each branch pipe is removed from the water tank, the truss is pushed to move to the lower section of the continuous beam, and then each branch pipe is connected to the water tank to spray water for curing the lower section of the continuous beam. This avoids the problem of multiple relocations of the spray curing system due to the advance of the cast-in-place concrete stage, which leads to complicated curing procedures. It also avoids the problems of low efficiency and high labor costs of manual watering curing.
[0024] Furthermore, gate valves are provided on the first, second, and third branch pipes to control the spraying of the corresponding branch pipes.
[0025] It has the following beneficial effects: the flow of water spray in each branch pipe can be controlled by the corresponding gate valve, so that the amount of water sprayed at each location can be determined according to the maintenance status of each location of the continuous beam.
[0026] Furthermore, the left truss, right truss, and inner formwork truss are all equipped with mounting rods, which cantilever out toward the rear side of the continuous beam, and the first nozzle, second nozzle, and third nozzle are mounted on the corresponding mounting rods.
[0027] It has the following beneficial effects: the mounting rod cantilevered out toward the rear side of the continuous beam, enabling the first, second, and third nozzles to spray deep into the cavity of the continuous beam.
[0028] Furthermore, a first guide seat is provided on both the left and right side walls of the continuous beam, and the left truss and the right truss are slidably assembled on the first guide seat on the corresponding side;
[0029] The continuous beam is provided with a second guide seat on its inner side, and the inner formwork truss is slidably assembled on the second guide seat on the corresponding side.
[0030] It has the following beneficial effects: the first guide seat and the second guide seat play a guiding role, allowing the left truss, the right truss and the inner formwork truss to slide on the continuous beam according to the maintenance position.
[0031] Furthermore, a first roller is rotatably mounted on the left truss, and the first roller is in contact with the top surface of the continuous beam so that the left truss can move on the continuous beam;
[0032] A second roller is rotatably mounted on the right truss, and the second roller is in contact with the top surface of the continuous beam so that the right truss can move on the continuous beam.
[0033] It has the following beneficial effects: the first and second rollers are in contact with the top surface of the continuous beam, which plays a role in supporting the truss and also facilitates the movement of the truss.
[0034] Furthermore, the first branch pipe, the second branch pipe, and the third branch pipe are each connected to a water pump, and the water pumps are connected to a water tank to supply water to the corresponding branch pipe.
[0035] It has the following beneficial effects: the water pump draws water from the water tank, and the drawn water is sprayed to each maintenance location through the first branch pipe, the second branch pipe and the third branch pipe respectively. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0041] The following describes various non-limiting embodiments of this utility model. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0042] This embodiment describes an automatic spray curing system for cantilever continuous beams, applied to cantilever cast-in-place continuous beams. The cantilever cast-in-place continuous beam in this embodiment includes a main body 1 and left wing plates 2 and right wing plates 3 respectively arranged on the left and right sides of the main body 1. The top surfaces of the left wing plates 2 and right wing plates 3 are flush with the top surface of the main body 1. The continuous beam has left and right walls and a lower side, and also contains a cavity 4. The continuous beam is a concrete structure, cast using cement, aggregate, steel, and other raw materials. After casting, it is promptly covered and watered for curing. The curing time is determined based on the type of concrete and environmental conditions, generally not less than 7 days.
[0043] Continuous beams require maintenance, primarily due to the following important reasons:
[0044] I. Ensuring Concrete Strength Growth
[0045] Concrete strength development requires suitable temperature and humidity conditions. Curing provides a relatively stable environment for concrete, allowing cement to fully hydrate and thus promoting normal strength growth. In large structures like cantilever continuous beams, proper concrete strength development is crucial for bearing the structure's own weight and the loads during subsequent construction and use.
[0046] II. Preventing concrete cracks
[0047] Drying shrinkage cracks: During the drying process, concrete gradually loses moisture, causing volume shrinkage. If curing is not timely, the surface moisture evaporates too quickly, and the internal moisture cannot be replenished in time, which will cause tensile stress on the surface. When the tensile stress exceeds the tensile strength of the concrete, drying shrinkage cracks will appear.
[0048] Temperature cracks: The hydration process of cement generates a large amount of heat, causing the internal temperature of the concrete to rise. In large-volume concrete structures such as cantilever continuous beams, this internal heat is not easily dissipated, resulting in a large temperature difference between the inside and outside, which can lead to temperature stress. Through proper curing and the adoption of appropriate temperature control measures, such as covering with insulation materials, the temperature difference between the inside and outside can be reduced, temperature stress can be lowered, and the formation of temperature cracks can be prevented.
[0049] III. Improving Concrete Durability
[0050] Proper curing can make the microstructure of concrete denser, reducing porosity and cracks, thereby improving the concrete's durability indicators such as impermeability and frost resistance. For structures like cantilever continuous beams that are exposed to the natural environment for extended periods, improved durability can extend their service life and reduce maintenance costs.
[0051] IV. Ensure the integrity and stability of the structure
[0052] A cantilever continuous beam is a monolithic structure, and the concrete properties of its various parts are interconnected. Comprehensive and standardized curing ensures uniform concrete performance across all parts, enabling the structure to work collaboratively under load, thereby guaranteeing the overall integrity and stability of the structure.
[0053] like Figure 1 As shown, in this embodiment, an automatic spraying maintenance system for a cantilever continuous beam includes a truss mounted on the continuous beam, water pipes mounted on the truss, and a water tank 5 connected to the water pipes. The water tank 5 is arranged on the top surface of the continuous beam and is connected to the truss. The truss includes an outer formwork truss slidably assembled on the outside of the continuous beam and an inner formwork truss 7 slidably assembled in the cavity 4 of the continuous beam. The outer formwork truss includes a left truss 6 for mounting on the left side of the continuous beam and a right truss 8 for mounting on the right side of the continuous beam. The left truss 6 partially encloses the left wing plate 2, left side wall, and lower side of the continuous beam, and the right truss 8 partially includes the right wing plate 3 and right side wall of the continuous beam. The left truss 6, right truss 8, and inner formwork truss 7 are all connected to the water tank 5.
[0054] In this embodiment, the water pipes include a first branch pipe 9, a second branch pipe 10, and a third branch pipe 11, all connected to the water tank 5. The first branch pipe 9 is located on the left truss 6 and has multiple first nozzles 12, which correspond to the left wing plate 2, the left side wall, and the lower side of the continuous beam, respectively, to spray water on the left wing plate 2, the left side wall, and the lower side of the continuous beam. The second branch pipe 10 is located on the inner formwork truss 7 and has multiple second nozzles 13, which correspond to the inner side wall, respectively, to spray water on the inner side wall of the continuous beam. The third branch pipe 11 is located on the right truss 8 and has multiple third nozzles 14, which correspond to the right wing plate 3 and the right side wall, respectively, to spray water on the right wing plate 3 and the right side wall of the continuous beam.
[0055] A recovery unit is provided between the left truss 6 and the right truss 8. The recovery unit is located on the lower side of the continuous beam and has a recovery trough 19 inside. The opening of the recovery trough 19 faces the lower side of the continuous beam so that water used for curing the outer side of the continuous beam falls into the recovery trough 19. A scraper 21 is fixedly mounted on the inner formwork truss 7. The scraper 21 moves with the inner formwork truss 7 to scrape water from the bottom of the inner side of the continuous beam so that the water falls into the recovery trough 19. In this embodiment, the movement of the inner formwork truss 7 can be done manually or by equipment. The opening of the recovery trough 19 has a filter plate 20 for filtering impurities. A recovery pipe 22 is provided on the left truss 6. One end of the recovery pipe 22 passes through the filter plate 20 and is inserted into the recovery trough 19. The other end of the recovery pipe 22 is connected to a water tank 5. A recovery pump is provided on the recovery pipe 22 to draw water from the recovery trough 19 back to the water tank 5.
[0056] During the maintenance of the continuous beam, the water falling from the continuous beam will fall into the recycling tank 19. The filter plate 20 filters the water after maintenance. Then the recycling pump will send the filtered water in the recycling tank 19 back to the water tank 5, realizing the reuse of maintenance water and reducing water waste.
[0057] This embodiment designs a truss on which the first branch pipe 9, the second branch pipe 10, and the third branch pipe 11 are arranged. The first nozzle 12, the second nozzle 13, and the third nozzle 14 spray water onto the continuous beam for curing. The truss is slidably assembled onto the continuous beam. When one section of the continuous beam has been cured, the branch pipes are removed from the water tank 5, the truss is moved to the lower section of the continuous beam, and then the branch pipes are reconnected to the water tank 5 to spray water onto the lower section of the continuous beam for curing. This avoids the problem of multiple relocations of the spray curing system due to the advance of the cast-in-place concrete stage, which would cause complex curing procedures. It also avoids the problems of low efficiency and high labor costs associated with manual watering curing.
[0058] In this embodiment, the bottom of the recycling tank 19 is a downward-concave arc shape. The downward-concave arc shape of the bottom of the tank allows the water falling into the recycling tank 19 to collect in the middle, making it easier for the recycling pipe 22 to recycle the water.
[0059] One end of the recovery pipe 22 is located at the lowest point of the bottom of the arc-shaped recovery tank 19. The fact that the recovery pipe 22 is located at the lowest point allows for the full recovery of water in the recovery tank 19, reducing the amount of water remaining in the recovery tank 19.
[0060] The filter plate 20 can be detachably assembled onto the recycling component. The recycling tank 19 has an annular support seat on its tank wall, and the filter plate 20 is fixed to the annular support seat by bolts.
[0061] In this embodiment, the recyclable component can be constructed using a waterproof tarpaulin. The edges of this tarpaulin are fixed to the left truss 6 and the right truss 8. After fixing, the horizontal width of the tarpaulin's cross-section is greater than the horizontal width of the lower side of the continuous beam. The edges of the tarpaulin can be directly fixed to the left truss 6 and the right truss 8, or they can be fixed to the left truss 6 and the right truss 8 using multiple ropes.
[0062] In this embodiment, the left truss 6, the right truss 8, and the inner formwork truss 7 all have mounting rods. These mounting rods extend horizontally and cantilever towards the rear of the continuous beam. The first nozzle 12, the second nozzle 13, and the third nozzle 14 are mounted on their respective mounting rods. The cantilevered extension of the mounting rods towards the rear of the continuous beam allows the first nozzle 12, the second nozzle 13, and the third nozzle 14 to spray deep into the cavity 4 of the continuous beam. In this embodiment, the rear of the continuous beam refers to the area where concrete has already been poured; the area where concrete has not been poured (or where concrete will be poured) is the front.
[0063] In this embodiment, the rear side of the mounting rod is overhanging by at least two meters to ensure that the cavity 4 of the continuous beam can be more thoroughly watered for curing. The first nozzle 12, the second nozzle 13, and the third nozzle 14 are all equipped with a spray diameter of four meters to ensure full coverage of the continuous beam and guarantee the quality of curing.
[0064] The continuous beam is provided with first guide seats 15 on both the left and right side walls. The left truss 6 and the right truss 8 are slidably assembled on the first guide seats 15 on the corresponding sides. When the maintenance position changes, the left truss 6 and the right truss 8 can slide along the first guide seats 15 to change the maintenance position and avoid the relocation and modification of the spray maintenance system.
[0065] The cavity 4 of the continuous beam is provided with a second guide seat 17. The inner formwork truss 7 is slidably assembled on the second guide seat 17 on the corresponding side. When the curing position changes, the inner formwork truss 7 can slide along the second guide seat 17, thereby changing the curing position, avoiding the relocation and modification of the spray curing system, and saving labor.
[0066] The first guide seat 15 and the second guide seat 17 serve as guides, enabling the left truss 6, the right truss 8 and the inner formwork truss 7 to slide on the continuous beam according to their maintenance positions.
[0067] To enable the left truss 6 to move more easily on the continuous beam, a first roller 18 is rotatably mounted on the left truss 6. The first roller 18 is in contact with the top surface of the continuous beam so that the left truss 6 can move on the continuous beam. At the same time, the first roller 18 plays a supporting role, supporting the left truss 6 on the continuous beam.
[0068] To facilitate easier movement of the right truss 8 on the continuous beam, a second roller 16 is rotatably mounted on the right truss 8. The second roller 16 is in contact with the top surface of the continuous beam to allow the right truss 8 to move on the continuous beam. At the same time, the second roller 16 serves as a support, supporting the right truss 8 on the continuous beam.
[0069] The first roller 18 and the second roller 16 are in contact with the top surface of the continuous beam, which serves to support the truss and also facilitates the movement of the truss.
[0070] In this embodiment, gate valves are provided on the first branch pipe 9, the second branch pipe 10, and the third branch pipe 11. By opening and closing the gate valves on the corresponding branch pipes, the spraying of that branch pipe is controlled, thereby controlling the water spraying maintenance system for the continuous beam. The flow of spraying in each branch pipe can be controlled by the corresponding gate valves, so that the amount of water sprayed at each location can be determined according to the maintenance status at each location of the continuous beam.
[0071] The first branch pipe 9, the second branch pipe 10, and the third branch pipe 11 are each connected to a water pump. These three water pumps are connected to a water tank 5 to supply water to their respective branch pipes. The water pumps draw water from the water tank 5, and the drawn water is sprayed through the first branch pipe 9, the second branch pipe 10, and the third branch pipe 11 to the designated maintenance locations. Simultaneously, the water tank 5 is connected to a water supply device that can supply water into the tank 5 to prevent it from running dry.
[0072] Each water pump is electrically connected to a controller, and each gate valve is also electrically connected to a controller, enabling the controller to control the operation of the corresponding gate valve and water pump. By controlling the operation of the gate valves and water pumps through the controller, the amount of water sprayed during maintenance can be controlled.
[0073] Temperature and humidity sensors are installed on the left truss 6, right truss 8, and inner mold truss 7 to detect the temperature and humidity at their respective locations. The temperature and humidity sensors are electrically connected to the controller to feed back their detected information, which is then used by the controller to adjust the operation of the corresponding water pumps and gate valves.
