Description

Technical Field

[0001] This utility model relates to the field of precast concrete slab curing technology, and more specifically, to a modularly installed precast concrete slab spray curing device. Background Technology

[0002] To improve construction speed and efficiency while ensuring building quality, and to guarantee lightweight, standardized, and regulated buildings, precast concrete slabs are increasingly being used in building structures. Precast concrete slabs such as partition walls and hollow core slabs are widely used in modern architecture. Due to the inherent characteristics of concrete, these precast slabs require spray curing after pouring and solidification to meet specific standards before they can be used. The traditional method involves laying precast slab blanks evenly on a flat surface and then spraying them with water. However, laying multiple precast slabs flat on the ground occupies a significant amount of space, resulting in low space utilization. Furthermore, the slabs need to be flipped, leading to low work efficiency.

[0003] To address the aforementioned issues, Chinese Patent Application No. 202420804540.4 discloses a precast slab spray curing device. The key technical features are: a base and two support frames symmetrically arranged on the base; multiple spray blocks evenly spaced along the Z-axis on each support frame; a support block between adjacent spray blocks on each support frame; multiple nozzles evenly spaced along the X-axis on each spray block; and a driving component on each support frame that allows the spray blocks to move along the Y-axis.

[0004] While the above method saves space and allows for simultaneous spray curing of both sides of the precast slab, its vertically arranged multi-layer structure makes loading or unloading the precast slab inconvenient. Furthermore, its integrated design makes modular disassembly and assembly impossible, resulting in transportation difficulties.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a modularly installed spray curing device for precast concrete slabs, which can be disassembled into multiple modules for independent transportation and is easy to assemble on-site, thus offering good ease of use.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a modularly installed precast concrete slab spray curing device, comprising a vertically arranged support column, two symmetrically detachably connected connecting plates at both ends of the support column, and a spraying device mounted on the support column. Multiple radial slots are arranged in a circular array on the opposite surfaces of the two connecting plates. The precast concrete slab is inserted into the two corresponding radial slots. The spraying device includes a connecting sleeve slidably mounted on the support column and circumferentially distributed spray pipes. The spray pipes extend into the gap between two adjacent precast concrete slabs. Nozzles are provided on the spray pipes facing the surfaces of the two adjacent precast concrete slabs. A drive assembly for driving the longitudinal reciprocating motion of the spraying device is detachably connected between the connecting plates and the spraying device.

[0008] In one embodiment, the support column is provided with connectors at both ends. Each connector includes a limiting section fixed to the end of the support column and a threaded section fixed to the end of the limiting section. The connecting plate is provided with a limiting groove that is adapted to the limiting section. After the threaded section extends out of the limiting groove, it is threadedly connected to a locking nut. The connecting plate is clamped between the locking nut and the end of the support column.

[0009] In one embodiment, the drive assembly includes an electric telescopic rod and an internally threaded sleeve rotatably and longitudinally slidably connected to the output end of the electric telescopic rod. A threaded connection groove is provided longitudinally through the connecting plate. A threaded connection part is provided on the cylinder of the electric telescopic rod. The threaded connection part is threadedly connected to the threaded connection groove. A threaded post is fixed on the connecting sleeve. The end of the internally threaded sleeve away from the electric telescopic rod is threadedly connected to the threaded post.

[0010] In one embodiment, the spraying device further includes a water supply hose for supplying water to the spray pipes.

[0011] In one embodiment, each radial slot on the lower connecting plate is provided with a booster chute extending to the ground on one side.

[0012] In summary, this utility model has the following beneficial effects: By setting radial slots on the annular connecting plate, precast concrete slabs can be vertically inserted and arranged in a circular array along the circumference. Compared to the traditional flat laying method, this effectively reduces the floor space required. Furthermore, the precast concrete slabs can be directly inserted into or removed from the radial slots from the side, effectively improving operational safety and efficiency. Simultaneously, the spray pipe extends into the gap between adjacent precast slabs, and the bidirectional nozzles can simultaneously and evenly spray the surfaces of both precast concrete slabs, avoiding the cumbersome manual flipping required for traditional single-sided spraying. Moreover, the support column, connecting plate, and drive assembly are all detachably connected, allowing for disassembly into multiple modules for independent transport and easy on-site assembly, resulting in good usability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3 As shown, an embodiment of this application provides a modularly installed precast concrete slab spray curing device, including a vertically arranged support column 1, two symmetrically detachably connected connecting plates 2 at both ends of the support column 1, and a spraying device mounted on the support column 1. Multiple radial slots 3 are arranged in a circular array on the opposite surfaces of the two connecting plates 2, and the precast concrete slabs are inserted into the two corresponding radial slots 3. The spraying device includes a connecting sleeve 5 slidably fitted onto the support column 1 and circumferentially distributed spray pipes 6. The spray pipes 6 extend into the gap between two adjacent precast concrete slabs, and nozzles 61 are arranged on the surfaces of the spray pipes 6 facing the two adjacent precast concrete slabs. Multiple nozzles 61 on each side are arranged in an array along the length of the spray pipe 6. A drive assembly for driving the longitudinal reciprocating motion of the spraying device is detachably connected between the connecting plates 2 and the spraying device.

[0019] When using the above-mentioned spray curing device, first, the connecting sleeve 5 of the spraying device is fitted onto the support column 1. Then, two annular connecting discs 2 are symmetrically installed at both ends of the support column 1. Rotate the connecting sleeve 5 so that the spray pipe 6 is positioned between two adjacent radial slots 3. Connect the drive assembly to the upper connecting disc 2 and the spraying device. Insert the precast concrete slab into the corresponding upper and lower radial slots 3. The spraying device moves longitudinally back and forth to evenly spray curing liquid onto the surfaces of two adjacent precast concrete slabs. The curing liquid can specifically be water. It should be noted that the multiple nozzles 61 on each side have sufficient spraying distance. Therefore, the outermost nozzle 61 on that side can also normally spray the curing liquid onto the surface of the precast concrete slab. Of course, in another embodiment, the nozzles 61 can also be extended. The length of the nozzles 61 on that side decreases from the outermost end to the inner end, and each nozzle 61 is perpendicular to the precast concrete slab on that side, which makes the spraying of the curing liquid more uniform.

[0020] In the above method, the precast concrete slabs can be vertically inserted and distributed in a circular array along the circumference by setting the radial slots 3 of the annular connecting plate 2. Compared with the traditional flat laying method, this effectively reduces the floor space occupied. The precast concrete slabs can be directly inserted into or pulled out of the radial slots 3 from the side, which effectively improves the safety and efficiency of operation. At the same time, the spray pipe 6 extends into the gap between adjacent precast slabs, and the bidirectional nozzles 61 can spray evenly on the surface of the precast concrete slabs on both sides at the same time, avoiding the cumbersome operation of manually flipping the slabs required by the traditional single-sided spraying. Furthermore, the support column 1, the connecting plate 2, and the drive components are all detachably connected and can be disassembled into multiple modules for independent transportation. They are also easy to assemble quickly on site and have good ease of use.

[0021] In this embodiment, connectors are provided at both ends of the support column 1. Each connector includes a limiting section 10 fixed to the end of the support column 1 and a threaded section 11 fixed to the end of the limiting section 10. The limiting section 10 has a polygonal cross-section, which prevents the connecting plate 2 from rotating circumferentially relative to the support column 1 and allows for precise alignment of the radial slots 3 on the two connecting plates 2. A limiting groove 13 is provided on the connecting plate 2, which is adapted to the limiting section 10. After the threaded section 11 extends out of the limiting groove 13, it is threadedly connected to a locking nut 12. The connecting plate 2 is clamped between the locking nut 12 and the end of the support column 1.

[0022] In this embodiment, the drive assembly includes an electric telescopic rod 9 and an internally threaded sleeve 8 rotatably and longitudinally slidably connected to the output end of the electric telescopic rod 9. A limiting step is provided inside the internally threaded sleeve 8. The output end of the electric telescopic rod 9 is slidably connected to the internally threaded sleeve 8, and a limiting block is provided at the end of the output end to abut against the limiting step. Thus, when the lower end of the internally threaded sleeve 8 is connected to the threaded post 7, the upper end of the internally threaded sleeve 8 will not disconnect from the output end of the electric telescopic rod 9. The electric telescopic rod 9 can specifically be an electric cylinder or a pneumatic cylinder. A threaded connection groove is longitudinally provided on the connecting disc 2. A threaded connection part 91 is provided on the cylinder body of the electric telescopic rod 9, and the threaded connection part 91 is threadedly connected to the threaded connection groove. A threaded post 7 is fixed on the connecting sleeve 5, and the end of the internally threaded sleeve 8 away from the electric telescopic rod 9 is threadedly connected to the threaded post 7.

[0023] When installing the above-mentioned drive assembly, first connect the threaded connection part 91 of the electric telescopic rod 9 to the threaded connection groove of the connecting plate 2, and then tighten the internal threaded sleeve onto the threaded post 7. It has the advantages of simple structure and convenient and quick disassembly and assembly.

[0024] In this embodiment, the spraying device also includes a water supply hose for supplying water to the spray pipe 6.

[0025] In this embodiment, each radial slot 3 on the lower connecting plate 2 is provided with a pusher chute 4 extending to the ground on one side. With the help of the pusher chute 4, the precast concrete slab can be pushed from the ground into the radial chute.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
