Description

Technical Field

[0001] The invention belongs to the technical field of spray curing, and in particular relates to a spray curing device and method for a prefabricated beam field. Background Art

[0002] The precast beam yard is where the precast concrete beams of bridges are produced. After the simple beams are produced on site, they are transported and erected on the bridge piers by beam transporters and beam erectors. Precast box beams are a common structural form for large-span bridges. After the precast box beams are demoulded, the top surface of the box beams needs to be covered with a permeable geotextile. The top plate is assisted by artificial watering to keep the geotextile in a moist state. The side of the box beam uses a sprinkler head to intermittently spray the inner and outer surfaces of the web and the bottom surface of the top plate every 10 to 15 minutes (the time is controlled according to the weather) to ensure that the beam body is in a moist state.

[0003] However, most of the existing box girder side spray curing equipment has atomizing nozzles equidistantly arranged laterally above the box girder side. Since the sprayed water is in an atomized state, the sprayed water mist can only contact the upper end of the box girder side, while the lower end of the box girder side needs to be soaked in the upper end surface before it can move downward along its surface. In this process, since the box girder surface is in a dry state, the water mist contacts the upper end of the box girder and gathers in the form of water droplets and moves downward, making it difficult for the water mist to contact the lower end of the box girder and soak the lower end of the box girder, thereby causing different humidity levels at the upper and lower ends of the box girder, which will affect the quality of box girder prefabrication. Therefore, a prefabricated beam field spray curing equipment is proposed. Summary of the invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a prefabricated beam yard spray curing equipment and method, wherein the box beam body is placed on the top of the support plate, and the operator pushes two limit plates toward the middle respectively, and the clamping plate slides outside the guide rod, so that the spacing between the limit plate and the side of the box beam body is 20 cm, and the position of the limit plate is fixed by rotating the fixing rod, and the butt pipe is connected to the water pump. The water pump injects water into the water injection pipe and is discharged through the atomizing nozzles equidistantly arranged on the water injection pipe. The sprayed water mist moves downward between the box beam body and the limit plate, and contacts with the upper end of the side of the box beam body, from The water mist can be in uniform contact with the side of the box girder body so that the surface humidity is consistent. At the same time, by increasing the distance between the limit plate and the box girder body, the contact between the water mist and the box girder body can be reduced, thereby controlling the humidity on the surface of the box girder body. This solves the problem that in the existing box girder spraying process, the sprayed water mist can only contact the upper end of the box girder side, while the lower end of the box girder side needs to be soaked in the upper end surface before it can move downward along its surface, resulting in difficulty for the water mist to contact the lower end of the box girder and difficulty in soaking the lower end of the box girder, thereby resulting in different humidity levels at the upper and lower ends of the box girder, which will affect the quality of the prefabrication of the box girder.

[0044] A gas injection assembly 400 connected to one side of the limiting plate 300, and an exhaust module 600 installed on the other side of the limiting plate 300;

[0045] The support assembly 500 includes a support plate 501, a guide rod 502 fixed to the top of the support plate 501, a clamping plate 504 fixed to the bottom of the limiting plate 300 and sliding outside the guide rod 502, and a fixing rod 503 fixed to the side of the limiting plate 300;

[0046] The spray assembly 200 includes a water injection pipe 201 installed on the top of the limiting plate 300, a connecting pipe 203 connected to the inside of the water injection pipe 201, and a butt pipe 202 installed at one end of the water injection pipe 201; the water injection pipe 201 is "U"-shaped and the transverse connection is a retractable bellows structure;

[0047] The box beam body 100 is placed on the top of the support plate 501, and the limit plate 300 is pushed. The clamping plate 504 slides outside the guide rod 502, and the distance between the limit plate 300 and the side of the box beam body 100 is adjusted to be 20 cm; atomizing nozzles are equidistantly arranged on the outside of the water injection pipe 201, and the docking pipe 202 is docked with the water pump. Water is injected into the water injection pipe 201 and sprayed out through the atomizing nozzle, and the water mist will enter between the limit plate 300 and the box beam body 100.

[0048] By placing the box beam body 100 on the top of the support plate 501, the clamping plate 504 slides on the outside of the guide rod 502, pushing the two limit plates 300 to move toward the middle, shortening the distance between the box beam body 100, and rotating the fixing rod 503 to make its bottom contact with the support plate 501, fixing the position of the limit plate 300, and compressing the corrugated pipe in the middle of the water injection pipe 201 during the movement of the two limit plates 300, so as to adapt to different spacings, docking the docking pipe 202 with the water pump, injecting water into the water injection pipe 201, and spraying water through the atomizing nozzle.

[0064] The second connecting rod 7027 moves in the opposite direction, driving the fixing plate 401 and the bellows 402 to compress the gas in the limiting plate 300 . The internal gas pushes the exhaust module 600 , blowing the water mist between the limiting plate 300 and the box beam body 100 to contact the box beam body 100 .

[0065] The second connecting rod 7027 moves toward one end to push the fixing plate 401 and stretch the bellows 402, thereby increasing the internal space of the limiting plate 300. During the increasing process, the external gas pushes the rubber pad 405, so that the air inlet pipe 403 is in an open state, and the external gas will enter the limiting plate 300.

[0066] At the same time, during the reverse movement of the second connecting rod 7027, the fixed plate 401 and the corrugated cover 402 are driven to compress the gas in the limit plate 300. The air pressure in the limit plate 300 increases, so that the rubber pad 405 fits with the support frame 404. The rubber pad 405 seals the air inlet pipe 403, and the gas is discharged to the surroundings through the exhaust module 600. During the discharge process, the water mist between the box beam body 100 and the limit plate 300 is blown, so that it contacts the side of the box beam body 100, and at the same time, dead angles can be avoided, thereby ensuring that the humidity on the side of the box beam body 100 remains consistent.

[0067] In another embodiment of the present invention, a method for curing a precast beam by spraying is provided:

[0068] First, place the box beam body 100 on the top of the support plate 501, and the operator pushes the two limit plates 300 toward the middle respectively, and the clamping plate 504 slides outside the guide rod 502, so that the distance between the limit plate 300 and the side of the box beam body 100 is 20 cm, and the fixing rod 503 is rotated to make its bottom contact with the support plate 501, and the position of the limit plate 300 is fixed. After the limit plate 300 is fixed, the docking pipe 202 is docked with the water pump, and the water pump will inject water into the water injection pipe 201 and discharge it through the atomizing nozzles equidistantly arranged on the water injection pipe 201. The sprayed water mist moves downward between the box beam body 100 and the limit plate 300, and contacts the upper end of the side of the box beam body 100, so that the water mist can evenly contact the side of the box beam body 100, so that the surface humidity is consistent;

[0069] Water enters the water storage pipe 7011 through the connecting pipe 203. The water storage pipe 7011 is in a high pressure state. Water enters the sleeve 7021 to push the sealing plate 7022 and the second connecting rod 7027 and stretch the second spring 7023. The fixing plate 401 is pushed by the second connecting rod 7027 to stretch the bellows 402, thereby increasing the internal space of the limit plate 300. During the increase process, the external gas pushes the rubber pad 405, so that the air inlet pipe 403 is in an open state, and the external gas will enter the limit plate 300.

[0070] The sealing plate 7022 drives the first connecting rod 7024 and the pushing plate 7025 during the movement. The pushing plate 7025 pushes the sealing ring 7028 during the movement to make it disengage from the limit of the clamping block 7013. Under the action of the water pressure in the water storage pipe 7011, the sealing ring 7028 is pushed to seal the sleeve 7021. At the same time, the sealing plate 7022 pushes the transmission rod 7034 and the movable plate 7032 during the movement, so that the sleeve 7021 and the drain pipe 7031 are in a connected state through the holes on the outside of the movable plate 7032. The water in the sleeve 7021 is discharged through the drain pipe 7031, and the second spring 7023 pulls the sealing plate 7022, the second connecting rod 7027 and the fixed plate 401 to move in opposite directions, and the sealing plate 7022 pushes the connecting plate 7033 and the movable plate 7032 to seal the sleeve 7021, and the first connecting rod 7024 drives the pushing plate 7025 to pull the sealing ring 7028 through the third spring 7026, so that it is separated from the sealing of one end of the sleeve 7021, and is limited by the clamping block 7013 and the first spring 7012;

[0071] During the reverse movement of the fixed plate 401 and the bellows 402, the gas in the limit plate 300 is squeezed by the fixed plate 401. At this time, the rubber pad 405 is subjected to air pressure to seal the air inlet pipe 403, and the exhaust module 600 is in an open state due to air pressure. The gas is discharged through the exhaust module 600. During the discharge process, the water mist between the limit plate 300 and the box beam body 100 is blown to make it evenly contact with the side of the box beam body 100. This reciprocating process makes the humidity on the side of the box beam body 100 more uniform.
