Description

Technical Field

[0001] The invention relates to the technical field of roof floating board construction, and in particular to a casting method for prefabricated casting of roof floating boards. Background Art

[0002] During the construction of traditional roof floating panels, the following process is usually followed: first, the prefabricated floating panels are lifted to the designated installation location outside the floor slab using lifting equipment. Then, the pre-embedded steel bars of the floating panels are tied and connected with the steel bars of the floor slab. Finally, concrete is poured at the connection between the floor slab and the floating panels, as well as the steel bar covering layer on the upper surface of the floor slab, so that the floating panels and the floor slab form an integrated structure.

[0003] However, this construction process has significant flaws: after the floating panels are hoisted to the designated installation location, the panels remain suspended and lack reliable anchoring during the process of tying and connecting the pre-embedded reinforcement to the floor slab. In this state, the panels are susceptible to displacement due to factors such as wind, mechanical vibration, and human manipulation. This instability directly leads to misalignment of the reinforcement, resulting in incorrect final installation position for the floating panels, which in turn affects the quality of the installation. Summary of the Invention

[0004] The present invention aims to provide a casting method for prefabricated casting of roof floating panels, which can avoid displacement of the floating panels during construction, thereby ensuring the accuracy of the floating panel installation position and further ensuring construction quality.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] 1) A casting method for prefabricated casting of roof floating panels, comprising the following steps:

[0007] Step 1: Determine the installation position of the floating board according to the design requirements, use the lifting equipment to transport the prefabricated floating board to the designated installation position outside the floor slab, and use the second infrared sensor inside the bracket to detect whether the floating board has reached the designated installation position and send the arrival signal to the microprocessor;

[0008] Step 2: After receiving the in-position signal, the microprocessor commands the first sliding mechanism and the second sliding mechanism at the bottom of the bracket to move toward each other, and uses the first pressure sensor and the second pressure sensor to detect the pressure value of the contact with the floating plate and send it to the microprocessor. When the pressure value reaches the standard pressure value, the microprocessor determines that the first sliding mechanism and the second sliding mechanism are in contact with the floating plate and commands the first sliding mechanism and the second sliding mechanism to stop. At this time, the first spray plate and the second spray plate are located directly above the pouring area where the floating plate and the floor slab are connected. At the same time, the microprocessor activates the first support assembly and the second support assembly to support the bottom of the floating plate.

[0009] Step 3: The distance between the first vertical rod and the second vertical rod is measured by the distance sensor and sent to the microprocessor. The microprocessor compares the distance value with the total length of the first spray plate and the second spray plate, and activates the corresponding spray mode according to the comparison result:

[0010] When the distance value is greater than the total length of the first spray plate and the second spray plate, the microprocessor commands the first spray plate and the second spray plate to start swinging, and at the same time commands the first spray assembly and the second spray assembly to start spraying concrete;

[0011] When the distance value is equal to the total length of the first spraying plate and the second spraying plate, the microprocessor commands the first spraying assembly and the second spraying assembly to spray concrete vertically downward;

[0012] When the distance value is less than the total length of the first spray plate and the second spray plate, the first spray plate and the second spray plate have an overlapping portion. The microprocessor detects the overlapping area through the first infrared sensor array and intelligently adjusts the spraying area.

[0013] The microprocessor gradually turns off the first spray assemblies in order from near to far according to the number of triggered first infrared sensors. When n first infrared sensors are triggered (n≥1), the microprocessor will turn off the first n first spray assemblies closest to the second spray plate, while maintaining the normal spraying state of the remaining first spray assemblies and all second spray assemblies, thereby achieving precise adjustment of the spray coverage.

[0014] 2) A casting method for precasting and casting floating roof panels according to 1), wherein:

[0015] In step 2, the bracket includes a retractable crossbar, with a first vertical bar and a second vertical bar extending downwardly provided at both ends of the crossbar, a distance sensor being embedded in the side of the first vertical bar facing the second vertical bar, and a first spray plate and a second spray plate being elongated and swingable provided in the bracket, the first spray plate and the second spray plate being parallel to the crossbar, the first spray plate being higher than the second spray plate, a plurality of first spray assemblies for spraying concrete being uniformly distributed in the first spray plate along its length, and a plurality of second spray assemblies for spraying concrete being uniformly distributed in the second spray plate along its length;

[0016] Several first infrared sensors corresponding to the second spray components are provided on the upper surface of the second spray plate. The first infrared sensor is located on the side of the second spray component close to the first spray plate. The bottoms of the first vertical rod and the second vertical rod are respectively provided with a first sliding mechanism and a second sliding mechanism that can be embedded in the I-beam and slide toward or away from each other along its length direction. A first pressure sensor is provided on the inside of the first sliding mechanism, a second pressure sensor is provided on the inside of the second sliding mechanism, and a second infrared sensor is embedded in the inside of the first sliding mechanism. The first pressure sensor, the second pressure sensor, the first spray plate, the second spray plate, the first spray component, the second spray component, the first infrared sensor, the second infrared sensor and the distance sensor are respectively electrically connected to the microprocessor.

[0017] In this invention, an I-beam is pre-installed at the edge of the floor slab where the floating slab is to be installed. The I-beam consists of horizontally arranged upper and lower flanges, and a vertically connected web. The first and second sliding mechanisms utilize an embedded design that precisely fits into the gaps formed by the upper and lower flanges and web of the I-beam, respectively. This ensures that the first and second sliding mechanisms remain stable as they move along the length of the I-beam.

[0018] When the lifting equipment lifts the floating plate to the outside of the I-beam, the second infrared sensor detects the arrival signal in real time and sends it to the microprocessor. Upon receiving the signal, the microprocessor commands the first and second sliding mechanisms to move toward each other. During this movement, the first and second pressure sensors measure pressure in real time and transmit it to the microprocessor.

[0019] The microprocessor stores the standard pressure values ​​for the first and second sliding mechanisms, respectively, when they engage the sides of the floating panel. When the pressure values ​​sent by the first and second pressure sensors reach these standard pressure values, indicating that the first and second sliding mechanisms are fully engaged with the floating panel, the microprocessor instructs the first and second sliding mechanisms to stop moving. The floating panel is now in its correct position, and the first and second spray plates are positioned directly above the pouring area where the floating panel connects to the floor slab. This arrangement allows the floating panel to be immediately secured when it is in its correct position, achieving intelligent positioning and ensuring accurate installation.

[0020] The distance sensor model is TFmini-i. The distance sensor measures the distance between the first and second vertical poles in real time and sends it to the microprocessor. The microprocessor stores the total length of the first and second spray plates. After receiving the actual distance value detected by the distance sensor, the microprocessor compares it with the total length of the first and second spray plates. The comparison method is as follows:

[0021] When the actual distance value is greater than the total length of the first spray plate and the second spray plate, the microprocessor commands the first spray plate and the second spray plate to start swinging, and at the same time commands the first spray assembly and the second spray assembly to start spraying concrete to ensure that the concrete completely covers the pouring area;

[0022] When the actual distance value is equal to the total length of the first spraying plate and the second spraying plate, the microprocessor commands the first spraying assembly and the second spraying assembly to spray concrete directly vertically downward;

[0023] When the actual distance value is less than the total length of the first spray plate and the second spray plate, the first spray plate and the second spray plate have an overlapping portion. The microprocessor detects the overlapping area through the first infrared sensor array and intelligently adjusts the spraying area.

[0024] Intelligently adjust the spraying area as follows:

[0025] The microprocessor automatically switches off the first spray assemblies, from closest to farthest, based on the number of triggered first infrared sensors, achieving intelligent adjustment of spray length. When n first infrared sensors are triggered (n ≥ 1), the microprocessor switches off the first n first spray assemblies closest to the second spray plate, while maintaining the normal spraying status of the remaining first spray assemblies and all second spray assemblies, thereby achieving precise adjustment of spray coverage.

[0026] With this setup, once the floating slab is fixed in position, concrete is automatically poured at the joint between the floating slab and the floor slab. This approach not only improves construction efficiency but also avoids the risks of high-altitude work associated with manual pouring, significantly enhancing construction safety.

[0027] 3) A casting method for precasting and casting floating roof panels according to 2), wherein:

[0028] In step 2, the upper surfaces of the first spray plate and the second spray plate are fixedly connected to the cross bars respectively, and the cross bars include a first cross bar and a second cross bar, and a telescopic rod is provided between the first cross bar and the second cross bar, and the two ends of the telescopic rod are fixedly connected to the ends of the first cross bar and the second cross bar respectively, the other end of the first cross bar is fixedly connected to the top of the first vertical bar, and the other end of the second cross bar is fixedly connected to the top of the second vertical bar, the first spray plate is fixedly connected to the first cross bar, and the second spray plate is fixedly connected to the second cross bar.

[0029] In the present invention, when the microprocessor commands the first and second sliding mechanisms to move toward or away from each other, they drive the first and second vertical rods connected thereto to move accordingly, which in turn drives the first and second crossbars to move accordingly. The first and second crossbars are connected by a telescopic rod. The movement of the first and second crossbars toward or away from each other causes the telescopic rod to extend or shorten accordingly, thereby enabling the first and second crossbars to achieve coordinated movement toward or away from each other.

[0030] 4) A casting method for precasting and casting floating roof panels according to 3), wherein:

[0031] In step 2, the top of the first spray plate is rotatably connected to a short sleeve rod extending upward, and the top of the second spray plate is rotatably connected to a long sleeve rod extending upward. The top surface of the short sleeve rod is fixedly connected to the bottom surface of the first cross bar, and the interior of the short sleeve rod is hollow. The top surface of the long sleeve rod is fixedly connected to the bottom surface of the second cross bar, and the interior of the long sleeve rod is hollow.

[0032] In the present invention, a short sleeve rod extends downward and is fixed to the bottom surface of the first crossbar, providing stable support for the first spray plate and ensuring its reliable connection to the first crossbar. The end of the short sleeve rod is rotatably connected to the first spray plate, allowing the first spray plate to flexibly swing and adjust its angle to meet different spraying needs, enhancing flexibility.

[0033] The extended rod allows the first spray plate to be higher than the second spray plate, thus accommodating different spraying requirements. The pivoting connection between the end of the rod and the second spray plate allows the second spray plate to be flexibly adjusted to meet different spraying requirements and enhance flexibility.

[0034] 5) A casting method for precasting and casting floating roof panels according to 4), wherein:

[0035] In step 2, a first fixing block is provided on the upper surface of the first spray plate, and the first fixing block can be embedded in the short sleeve rod. A first rotating shaft is fixedly passed through the first fixing block and is arranged in parallel. The axis of the first rotating shaft is perpendicular to the axis of the first cross bar. Both ends of the first rotating shaft are respectively passed through the side walls of the short sleeve rod. One end of the first rotating shaft passing through the side wall of the short sleeve rod is connected to a first rotating motor. The first rotating motor is located on the outer wall of the short sleeve rod, and a gap is provided between the short sleeve rod and the first spray plate.

[0036] A second fixed block is provided on the upper surface of the second spray plate, and the second fixed block can be embedded in the long sleeve rod. A second rotating shaft arranged in parallel is fixedly passed through the second fixed block, and the axis of the second rotating shaft is perpendicular to the axis of the second cross bar. The two ends of the second rotating shaft are respectively passed through the side walls of the long sleeve rod, and the end of the second rotating shaft passing through the side wall of the long sleeve rod is connected to the second rotating motor, and the second rotating motor is located on the outer wall of the long sleeve rod. A gap is provided between the long sleeve rod and the second spray plate, and the first rotating motor and the second rotating motor are respectively electrically connected to the microprocessor.

[0037] In the present invention, when the distance sensor measures in real time that the distance between the first vertical rod and the second vertical rod is greater than the total length of the first spraying plate and the second spraying plate, the microprocessor commands the first spraying assembly and the second spraying assembly to start spraying concrete, and at the same time commands the first rotating motor and the second rotating motor to start, driving the first rotating shaft and the second rotating shaft to rotate, thereby driving the first spraying plate and the second spraying plate to swing, so that the concrete can completely cover the pouring area directly above the connection between the floating plate and the floor slab.

[0038] 6) A casting method for precasting and casting floating roof panels according to 1), wherein:

[0039] In step three, the first spray assembly includes a first storage chamber, the first storage chamber is uniformly distributed in the first spray plate along the length direction of the first spray plate, the bottom surface of the first spray plate is provided with a plurality of first spray ports corresponding one-to-one and connected to the first storage chambers, a first valve is provided in the first spray port, and the side surface of the first spray plate is provided with a plurality of first feed ports corresponding one-to-one and connected to the first storage chambers, the first feed ports are connected to a first pipeline, all the first pipelines are commonly connected to a first main pipeline, the first main pipeline is connected to a storage barrel, and the first main pipeline is provided with a first suction pump;

[0040] The second spray assembly includes a second storage chamber, which is evenly distributed in the second spray plate along the length direction of the second spray plate. The bottom surface of the second spray plate is provided with several second spray ports that correspond one-to-one and are connected to the second storage chambers. A second valve is provided in the second spray port. The side of the second spray plate is provided with several second feed ports that correspond one-to-one and are connected to the second storage chambers. The second feed ports are connected to a secondary pipeline, and all secondary pipelines are commonly connected to a second main pipeline. The second main pipeline is connected to the storage barrel. A second suction pump is provided on the second main pipeline. The first valve, the second valve, the first suction pump and the second suction pump are electrically connected to the microprocessor respectively.

[0041] In the present invention, when the distance sensor measures in real time that the distance between the first vertical rod and the second vertical rod is greater than or equal to the total length of the first spray plate and the second spray plate, the microprocessor commands the first suction pump and the second suction pump to start, and simultaneously commands the first valve and the second valve to open.

[0042] The first suction pump pumps the concrete in the storage barrel through the first main pipe to each primary pipe, then enters the first storage chamber, and finally sprays it through the first spraying port; the second suction pump pumps the concrete in the storage barrel through the second main pipe to each secondary pipe, then enters the second storage chamber, and finally sprays it through the second spraying port.

[0043] When the distance sensor measures in real time that the distance between the first vertical rod and the second vertical rod is less than the total length of the first spray plate and the second spray plate, the microprocessor gradually closes the first valve in order from near to far according to the number of first infrared sensors triggered, thereby realizing intelligent adjustment of the spraying length.

[0044] When n first infrared sensors are triggered (n≥1), the microprocessor will close the first n first valves closest to the second spray plate, while maintaining the normal spraying state of the remaining first valves and all second valves, thereby achieving precise adjustment of the spray coverage rate.

[0045] 7) A casting method for precasting and casting floating roof panels according to 1), wherein:

[0046] In step 2, the first sliding mechanism includes a first slider in an inverted U shape, the first slider is provided with a first roller assembly that can be embedded in the I-beam and roll along the axial direction thereof, the first slider includes a first transverse plate, the upper surface of the first transverse plate is fixedly connected to the bottom surface of the first vertical rod, and first side plates are respectively provided at both ends of the first transverse plate, the second infrared sensor is embedded in the side of one of the first side plates facing the second sliding mechanism, the second infrared sensor is used to detect the in-position signal of the floating plate, the first pressure sensor is located on the side of one of the first side plates facing the second sliding mechanism, the first pressure sensor is used to detect the fit state of the floating plate and the first sliding mechanism, the bottom of the first side plate is connected to a first fixed plate arranged in a transverse direction, the bottom surface of the first fixed plate is provided with a first liftable support assembly, and the first support assembly is used to support the floating plate;

[0047] The second sliding mechanism includes a second slider in an inverted U shape, a second rolling assembly that can be embedded in the I-beam and roll along its axial direction is provided in the second slider, the second slider includes a second transverse plate, the upper surface of the second transverse plate is fixedly connected to the bottom surface of the second vertical rod, and second side plates are respectively provided at both ends of the second transverse plate. The second pressure sensor is located on the side of one of the second side plates facing the first sliding mechanism, and the second pressure sensor is used to detect the fit state of the floating plate and the second sliding mechanism. The bottom of the second side plate is connected to a second fixed plate arranged in a transverse direction, and the bottom surface of the second fixed plate is provided with a liftable second support assembly, and the second support assembly is used to support the floating plate, and the first support assembly, the second support assembly, the first roller assembly and the second roller assembly are respectively electrically connected to the microprocessor.

[0048] In the present invention, when the lifting equipment lifts the floating plate to the outside of the I-beam, the second infrared sensor detects the floating plate's arrival signal in real time and sends a signal to the microprocessor. Upon receiving the signal, the microprocessor instructs the first and second roller assemblies to move toward each other, thereby driving the first and second slide blocks to move accordingly. During this process, the first and second pressure sensors detect pressure values ​​in real time and transmit them to the microprocessor.

[0049] The microprocessor stores standard pressure values ​​when the first sliding mechanism and the second sliding mechanism are respectively in contact with the side surfaces of the floating plate. When the pressure values ​​sent by the first pressure sensor and the second pressure sensor reach the standard pressure values, it indicates that the first sliding mechanism and the second sliding mechanism are respectively fully in contact with the floating plate. The microprocessor commands the first roller assembly and the second roller assembly to stop moving. At this time, the first spray plate and the second spray plate are located directly above the pouring area where the floating plate is connected to the floor slab.

[0050] The microprocessor then commands the synchronous rise of the first and second support assemblies to support the bottom of the floating slab. This support effectively distributes the weight of the floating slab and significantly reduces the load on the lifting equipment, thus achieving energy savings and lowering overall construction costs. The entire process is automated through an intelligent control system, ensuring the accuracy and reliability of the support.

[0051] 8) A casting method for precasting and casting floating roof panels according to 7), wherein:

[0052] The first roller assembly includes two first rollers corresponding to the first side plates one by one, the first rollers are located on the inner side of the first side plate, the axes of the first rollers are parallel to the first side plate, a first roller shaft is coaxially provided inside the first roller, the top surface of the first roller shaft is rotatably connected to the first transverse plate, the bottom surface of the first roller shaft is rotatably connected to the first fixed plate, the top surface of one of the first roller shafts is connected to a first micro motor, and the first micro motor is located on the lower surface of the transverse plate;

[0053] The first roller assembly includes two first rollers corresponding to the first side plates one by one, the first rollers are located on the inner side of the first side plate, the axes of the first rollers are parallel to the first side plate, a first roller shaft is coaxially provided inside the first roller, the top surface of the first roller shaft is rotatably connected to the first transverse plate, the bottom surface of the first roller shaft is rotatably connected to the first fixed plate, the top surface of one of the first roller shafts is connected to a first micro motor, and the first micro motor is located on the lower surface of the transverse plate;

[0054] In the present invention, when the lifting equipment hoists the floating plate to the outside of the I-beam, the second infrared sensor detects the floating plate's arrival signal in real time and sends a signal to the microprocessor. Upon receiving the signal, the microprocessor activates the first and second micromotors. The activation of the first micromotor rotates the first roller connected to it, which in turn drives the first roller connected to it to roll along the axis of the I-beam, thereby driving the first slider connected to it to move with it. The movement of the first slider also drives the other first roller within it to roll, ensuring smooth and continuous movement of the first slider.

[0055] Similarly, activation of the second micromotor drives the second roller connected to it to rotate, thereby driving the second roller connected to it to roll along the axis of the I-beam, thereby driving the second slider connected to it to move. The movement of the second slider drives the other first roller within it to roll, ensuring smooth and continuous movement of the second slider. The smooth movement of the first and second sliders drives the movement of the first and second vertical rods, thereby driving the smooth movement of the first and second spray plates.

[0056] 9) A casting method for precasting and casting floating roof panels according to 1), wherein:

[0057] In step 2, the first support assembly includes a first telescopic pump, the first telescopic pump is located on the bottom surface of one of the first fixed plates, the free end of the telescopic rod of the first telescopic pump is connected to an inclined first support rod, and the end of the first support rod extends obliquely upward;

[0058] The second support assembly includes a second telescopic pump, which is located on the bottom surface of one of its second fixed plates. The free end of the telescopic rod of the second telescopic pump is connected to a second support oblique rod that is arranged obliquely. The end of the second support oblique rod extends obliquely upward. The first telescopic pump and the second telescopic pump are respectively electrically connected to the microprocessor.

[0059] In the present invention, the microprocessor presets the lengths by which the telescopic rods of the first and second telescopic pumps must retract when the first and second supporting diagonal rods contact the bottom of the floating board. When the first and second sliding mechanisms are fully engaged with the floating board, the microprocessor commands the first and second telescopic pumps to activate simultaneously based on the preset retraction lengths. The telescopic rods of the first and second telescopic pumps retract by the preset retraction lengths, respectively driving the connected first and second supporting diagonal rods upward.

[0060] As the first and second diagonal support rods extend diagonally upward, their ends precisely contact the bottom of the floating slab, forming a stable support structure. This coordinated support effectively distributes the weight of the floating slab, significantly reducing the load on the lifting equipment, achieving energy savings and lowering overall construction costs. The entire process is automated through an intelligent control system, ensuring precise and reliable support.

[0061] Compared with the prior art, the present invention also has the following technical effects:

[0062] The present invention uses a microprocessor to control the movement of the first sliding mechanism and the second sliding mechanism, which can achieve precise positioning of the floating plate and ensure its accurate installation position. At the same time, the microprocessor works in conjunction with the distance sensor and the first infrared sensor to intelligently adjust the spraying mode of the first spray assembly and the second spray assembly. Compared with the existing technology, the present invention can automatically pour concrete at the connection between the floating plate and the floor slab after the position of the floating plate is fixed, which not only improves construction efficiency, but also avoids the high-altitude operation risks brought by manual pouring, and significantly improves construction safety. In addition, the bottom of the floating plate is supported by the first support assembly and the second support assembly, which effectively shares the weight of the floating plate, reduces the load on the lifting equipment, achieves energy saving effects and reduces overall construction costs.

[0068] The reference numerals in the drawings of the specification include: a first vertical rod 1, a second vertical rod 2, a distance sensor 3, a first spray plate 4, a second spray plate 5, a first infrared sensor 6, a first sliding mechanism 7, a second sliding mechanism 8, a first pressure sensor 9, a second pressure sensor 10, a first cross bar 11, a second cross bar 12, a telescopic rod 13, a short sleeve rod 14, a long sleeve rod 15, a first fixed block 16, a first rotating shaft 17, a first rotating motor 18, a second fixed block 19, a second rotating shaft 20, a second rotating motor 21, a first fixed block 1 A storage chamber 22, a first valve 23, a first pipeline 24, a first main pipeline 25, a storage barrel 26, a first suction pump 27, a second storage chamber 28, a second valve 29, a second pipeline 30, a second main pipeline 31, a second suction pump 32, a first horizontal plate 33, a first side plate 34, a first fixed plate 35, a first roller 36, a first roller 37, a first micromotor 38, a first telescopic pump 39, a first supporting diagonal rod 40, a second telescopic pump 41, a second supporting diagonal rod 42, and a second infrared sensor 43.

[0069] For example, see Figure 1 As shown, a casting method for prefabricated casting of roof floating panels in this embodiment includes the following steps:

[0070] Step 1: Determine the installation position of the floating board according to the design requirements, use the lifting equipment to transport the prefabricated floating board to the designated installation position outside the floor slab, and use the second infrared sensor inside the bracket to detect whether the floating board has reached the designated installation position and send the arrival signal to the microprocessor;

[0071] Step 2: After receiving the in-position signal, the microprocessor commands the first sliding mechanism and the second sliding mechanism at the bottom of the bracket to move toward each other, and uses the first pressure sensor and the second pressure sensor to detect the pressure value of the contact with the floating plate and send it to the microprocessor. When the pressure value reaches the standard pressure value, the microprocessor determines that the first sliding mechanism and the second sliding mechanism are in contact with the floating plate and commands the first sliding mechanism and the second sliding mechanism to stop. At this time, the first spray plate and the second spray plate are located directly above the pouring area where the floating plate and the floor slab are connected. At the same time, the microprocessor activates the first support assembly and the second support assembly to support the bottom of the floating plate.

[0072] Step 3: The distance between the first vertical rod and the second vertical rod is measured by the distance sensor and sent to the microprocessor. The microprocessor compares the distance value with the total length of the first spray plate and the second spray plate, and activates the corresponding spray mode according to the comparison result:

[0073] When the distance value is greater than the total length of the first spray plate and the second spray plate, the microprocessor commands the first spray plate and the second spray plate to start swinging, and at the same time commands the first spray assembly and the second spray assembly to start spraying concrete;

[0074] When the distance value is equal to the total length of the first spraying plate and the second spraying plate, the microprocessor commands the first spraying assembly and the second spraying assembly to spray concrete vertically downward;

[0075] When the distance value is less than the total length of the first spray plate and the second spray plate, the first spray plate and the second spray plate have an overlapping portion. The microprocessor detects the overlapping area through the first infrared sensor array and intelligently adjusts the spraying area.

[0076] The microprocessor gradually turns off the first spray assemblies in order from near to far according to the number of triggered first infrared sensors. When n first infrared sensors are triggered (n≥1), the microprocessor will turn off the first n first spray assemblies closest to the second spray plate, while maintaining the normal spraying state of the remaining first spray assemblies and all second spray assemblies, thereby achieving precise adjustment of the spray coverage.

[0077] See also Figure 2 As shown, in step 2, the bracket includes a retractable cross bar, and the two ends of the cross bar are respectively provided with a first vertical bar 1 and a second vertical bar 2 extending downward, and the first vertical bar 1 is embedded with a distance sensor 3 on the side facing the second vertical bar 2. The bracket is provided with a first spray plate 4 and a second spray plate 5 that are long and swingable. The first spray plate 4 and the second spray plate 5 are both parallel to the cross bar, and the first spray plate 4 is higher than the second spray plate 5. Four first spray assemblies for spraying concrete are evenly distributed in the first spray plate 4 along its length, and four second spray assemblies for spraying concrete are provided in the second spray plate 5 along its length.

[0078] Among them, the upper surface of the second spray plate 5 is provided with four first infrared sensors 6 corresponding one to one with the second spray assembly. The first infrared sensor 6 is located on the side of the second spray assembly close to the first spray plate 4. The bottoms of the first vertical rod 1 and the second vertical rod 2 are respectively provided with a first sliding mechanism 7 and a second sliding mechanism 8 that can be embedded in the I-beam and slide toward or away from each other along its length direction. A first pressure sensor 9 is provided on the inside of the first sliding mechanism 7, and a second pressure sensor 10 is provided on the inside of the second sliding mechanism 8. A second infrared sensor 43 is embedded on the inside of the first sliding mechanism 7. The first pressure sensor 9, the second pressure sensor 10, the first spray plate 4, the second spray plate 5, the first spray assembly, the second spray assembly, the first infrared sensor 6, the second infrared sensor 43 and the distance sensor 3 are respectively electrically connected to the microprocessor.

[0079] In this embodiment, an I-beam is pre-installed at the edge of the floor slab where the floating slab is to be installed. The I-beam consists of horizontally arranged upper and lower flanges, and a vertically connected web. The first and second sliding mechanisms 7 and 8 employ an embedded design, precisely fitting into the gaps formed by the upper and lower flanges and web of the I-beam, respectively. This ensures that the first and second sliding mechanisms 7 and 8 remain stable as they move along the length of the I-beam.

[0080] When the lifting equipment hoists the floating plate to the outside of the I-beam, the second infrared sensor 43 detects the floating plate's arrival signal in real time and sends a signal to the microprocessor. Upon receiving the signal, the microprocessor instructs the first and second sliding mechanisms 7 and 8 to move toward each other. During this movement, the first and second pressure sensors 9 and 10 measure the pressure in real time and transmit it to the microprocessor.

[0081] The microprocessor stores the standard pressure values ​​for the first and second sliding mechanisms 7 and 8, respectively, when they engage the sides of the floating panel. When the pressure values ​​sent by the first and second pressure sensors 9 and 10 reach these standard pressure values, indicating that the first and second sliding mechanisms 7 and 8 are fully engaged with the floating panel, the microprocessor commands the first and second sliding mechanisms 7 and 8 to stop moving. The floating panel is now in its correct position, and the first and second spray plates 4 and 5 are positioned directly above the pouring area where the floating panel connects to the floor slab. This arrangement allows the floating panel to be immediately secured when it is in its correct position, achieving intelligent positioning and ensuring accurate installation.

[0082] The distance sensor 3, model TFmini-i, measures the distance between the first vertical rod 1 and the second vertical rod 2 in real time and sends it to the microprocessor. The microprocessor stores the total length of the first spray plate 4 and the second spray plate 5. After receiving the actual distance value detected by the distance sensor 3, the microprocessor compares it with the total length of the first spray plate 4 and the second spray plate 5. The comparison method is as follows:

[0083] When the actual distance value is greater than the total length of the first spray plate 4 and the second spray plate 5, the microprocessor commands the first spray plate 4 and the second spray plate 5 to start swinging, and at the same time commands the first spray assembly and the second spray assembly to start spraying concrete to ensure that the concrete completely covers the pouring area;

[0084] When the actual distance value is equal to the total length of the first spraying plate 4 and the second spraying plate 5, the microprocessor commands the first spraying assembly and the second spraying assembly to spray concrete directly vertically downward;

[0085] When the actual distance value is less than the total length of the first spray plate 4 and the second spray plate 5, the first spray plate 4 and the second spray plate 5 have an overlapping portion. The microprocessor detects the overlapping area through the first infrared sensor 6 array and intelligently adjusts the spraying area.

[0086] Intelligently adjust the spraying area as follows:

[0087] The microprocessor gradually shuts down the first spray assemblies, from near to far, based on the number of triggered first infrared sensors 6, achieving intelligent adjustment of the spray length. When n first infrared sensors 6 are triggered (n ≥ 1), the microprocessor shuts down the first n first spray assemblies closest to the second spray plate 5, while maintaining the normal spraying state of the remaining first spray assemblies and all second spray assemblies, thereby achieving precise adjustment of the spray coverage.

[0088] With this setup, once the floating slab is fixed in position, concrete is automatically poured at the joint between the floating slab and the floor slab. This approach not only improves construction efficiency but also avoids the high-altitude work risks associated with manual pouring, significantly enhancing construction safety.

[0089] In step 2, the upper surfaces of the first spray plate 4 and the second spray plate 5 are respectively fixedly connected to the cross bars, which include a first cross bar 11 and a second cross bar 12. A telescopic rod 13 is provided between the first cross bar 11 and the second cross bar 12. The two ends of the telescopic rod 13 are respectively fixedly connected to the ends of the first cross bar 11 and the second cross bar 12. The other end of the first cross bar 11 is fixedly connected to the top of the first vertical bar 1, and the other end of the second cross bar 12 is fixedly connected to the top of the second vertical bar 2. The first spray plate 4 is fixedly connected to the first cross bar 11, and the second spray plate 5 is fixedly connected to the second cross bar 12.

[0090] In this embodiment, when the microprocessor commands the first sliding mechanism 7 and the second sliding mechanism 8 to move toward or away from each other, the first vertical rod 1 and the second vertical rod 2 connected thereto are driven to move accordingly, thereby driving the corresponding movement of the first crossbar 11 and the second crossbar 12. The first crossbar 11 and the second crossbar 12 are connected by a telescopic rod 13. The movement of the first crossbar 11 and the second crossbar 12 toward or away from each other causes the telescopic rod 13 to extend or shorten accordingly, thereby enabling the first crossbar 11 and the second crossbar 12 to achieve coordinated movement toward or away from each other.

[0091] In step 2, the top of the first spray plate 4 is rotatably connected to a short sleeve rod 14 extending upward, and the top of the second spray plate 5 is rotatably connected to a long sleeve rod 15 extending upward. The top surface of the short sleeve rod 14 is fixedly connected to the bottom surface of the first cross bar 11, and the interior of the short sleeve rod 14 is hollow. The top surface of the long sleeve rod 15 is fixedly connected to the bottom surface of the second cross bar 12, and the interior of the long sleeve rod 15 is hollow.

[0092] In this embodiment, the short sleeve rod 14 extends downward and is fixed to the bottom surface of the first crossbar 11, providing stable support for the first spray plate 4 and ensuring its reliable connection with the first crossbar 11. The end of the short sleeve rod 14 is rotatably connected to the first spray plate 4, allowing the first spray plate 4 to flexibly swing and adjust its angle to meet different spraying needs and enhance flexibility.

[0093] The long sleeve rod 15 is long, allowing the first spray plate 4 to be higher than the second spray plate 5, thereby adapting to different spraying needs. The rotatable connection between the end of the long sleeve rod 15 and the second spray plate 5 allows the second spray plate 5 to flexibly swing and adjust its angle to meet different spraying needs, enhancing flexibility.

[0094] In step 2, a first fixed block 16 is provided on the upper surface of the first spray plate 4, and the first fixed block 16 can be embedded in the short sleeve rod 14. A first rotating shaft 17 is fixedly penetrated in the first fixed block 16 in parallel. The axis of the first rotating shaft 17 is perpendicular to the axis of the first cross bar 11. The two ends of the first rotating shaft 17 are respectively passed through the side walls of the short sleeve rod 14. One end of the first rotating shaft 17 passing through the side wall of the short sleeve rod 14 is connected to the first rotating motor 18. The first rotating motor 18 is located on the outer wall of the short sleeve rod 14, and a gap is provided between the short sleeve rod 14 and the first spray plate 4.

[0095] Secondly, a second fixed block 19 is provided on the upper surface of the second spray plate 5, and the second fixed block 19 can be embedded in the long sleeve rod 15. A second rotating shaft 20 is fixedly penetrated in parallel in the second fixed block 19. The axis of the second rotating shaft 20 is perpendicular to the axis of the second cross bar 12. The two ends of the second rotating shaft 20 are respectively passed through the side walls of the long sleeve rod 15. The end of the second rotating shaft 20 passing through the side wall of the long sleeve rod 15 is connected to the second rotating motor 21. The second rotating motor 21 is located on the outer side wall of the long sleeve rod 15. A gap is provided between the long sleeve rod 15 and the second spray plate 5. The first rotating motor 18 and the second rotating motor 21 are respectively electrically connected to the microprocessor.

[0096] In this embodiment, when the distance sensor 3 measures in real time that the distance between the first vertical rod 1 and the second vertical rod 2 is greater than the total length of the first spraying plate 4 and the second spraying plate 5, the microprocessor commands the first spraying assembly and the second spraying assembly to start spraying concrete, and at the same time commands the first rotating motor 18 and the second rotating motor 21 to start, driving the first rotating shaft 17 and the second rotating shaft 20 to rotate, thereby driving the first spraying plate 4 and the second spraying plate 5 to swing, so that the concrete can completely cover the pouring area directly above the connection between the floating plate and the floor slab.

[0097] See also Figure 4As shown, in step three, the first spray assembly includes a first storage chamber 22, and the first storage chamber 22 is evenly distributed in the first spray plate 4 along the length direction of the first spray plate 4. The bottom surface of the first spray plate 4 is provided with several first spray ports corresponding one-to-one and connected to the first storage chamber 22, and a first valve 23 is provided in the first spray port.

The first valve 23, the second valve 29, the first suction pump 27 and the second suction pump 32 are respectively electrically connected to the microprocessor.

[0099] In this embodiment, when the distance sensor 3 measures in real time that the distance between the first vertical rod 1 and the second vertical rod 2 is greater than or equal to the total length of the first spray plate 4 and the second spray plate 5, the microprocessor commands the first suction pump 27 and the second suction pump 32 to start, and at the same time commands the first valve 23 and the second valve 29 to open.

[0100] The first suction pump 27 pumps the concrete in the storage barrel 26 into each primary pipe 24 through the first main pipe 25, then enters the first storage chamber 22, and is finally sprayed through the first spraying port; the second suction pump 32 pumps the concrete in the storage barrel 26 into each secondary pipe 30 through the second main pipe 31, then enters the second storage chamber 28, and is finally sprayed through the second spraying port.

[0101] When the distance sensor 3 measures in real time that the distance between the first vertical rod 1 and the second vertical rod 2 is less than the total length of the first spray plate 4 and the second spray plate 5, the microprocessor gradually closes the first valve 23 in order from near to far according to the number of first infrared sensors 6 triggered, thereby realizing intelligent adjustment of the spraying length.

[0102] When n first infrared sensors 6 are triggered (n≥1), the microprocessor will close the first n first valves 23 closest to the second spray plate 5, while maintaining the normal spraying state of the remaining first valves 23 and all second valves 29, thereby achieving precise adjustment of the spray coverage.

[0103] See also Figure 3 As shown, in step 2, the first sliding mechanism 7 includes a first slider in an inverted U shape, and the first slider is provided with a first roller assembly that can be embedded in the I-beam and roll along its axial direction. The first slider includes a first horizontal plate 33, and the upper surface of the first horizontal plate 33 is fixedly connected to the bottom surface of the first vertical rod 1. First side plates 34 are respectively provided at both ends of the first horizontal plate 33. The second infrared sensor 43 is embedded in the side of one of the first side plates 34 facing the second sliding mechanism 8. The second infrared sensor 43 is used to detect the in-position signal of the floating plate. The first pressure sensor 9 is located on the side of one of the first side plates 34 facing the second sliding mechanism 8. The first pressure sensor 9 is used to detect the fit state of the floating plate and the first sliding mechanism 7. The bottom of the first side plate 34 is connected to a first fixed plate 35 arranged horizontally. The bottom surface of the first fixed plate 35 is provided with a first support assembly that can be lifted and lowered. The first support assembly is used to support the floating plate.

[0104] Among them, the second sliding mechanism 8 includes a second slider in an inverted U shape, and a second rolling assembly that can be embedded in the I-beam and roll along its axial direction is provided in the second slider. The second slider includes a second horizontal plate, and the upper surface of the second horizontal plate is fixedly connected to the bottom surface of the second vertical rod 2. Second side plates are respectively provided at both ends of the second horizontal plate. The second pressure sensor 10 is located on the side of one of the second side plates facing the first sliding mechanism 7. The second pressure sensor 10 is used to detect the fitting state of the floating plate and the second sliding mechanism 8. The bottom of the second side plate is connected to a second fixed plate arranged in a horizontal direction, and the bottom surface of the second fixed plate is provided with a liftable second support assembly. The second support assembly is used to support the floating plate, and the first support assembly, the second support assembly, the first roller assembly and the second roller assembly are respectively electrically connected to the microprocessor.

[0105] In this embodiment, when the lifting equipment lifts the floating plate to the outside of the I-beam, the second infrared sensor 43 detects the floating plate arrival signal in real time and sends a signal to the microprocessor. Upon receiving the signal, the microprocessor instructs the first and second roller assemblies to move toward each other, thereby driving the first and second slide blocks to move accordingly. During this process, the first and second pressure sensors 9 and 10 detect pressure values ​​in real time and transmit them to the microprocessor.

[0106] The microprocessor stores the standard pressure values ​​when the first sliding mechanism 7 and the second sliding mechanism 8 are respectively in contact with the side surfaces of the floating plate. When the pressure values ​​sent by the first pressure sensor 9 and the second pressure sensor 10 reach the standard pressure values, it indicates that the first sliding mechanism 7 and the second sliding mechanism 8 are respectively fully in contact with the floating plate. The microprocessor instructs the first roller assembly and the second roller assembly to stop moving. At this time, the first spray plate 4 and the second spray plate 5 are located directly above the pouring area where the floating plate and the floor slab are connected.

[0107] The microprocessor then commands the synchronous rise of the first and second support assemblies to support the bottom of the floating slab. This support effectively distributes the weight of the floating slab and significantly reduces the load on the lifting equipment, thus achieving energy savings and lowering overall construction costs. The entire process is automated through an intelligent control system, ensuring the accuracy and reliability of the support.

[0108] The first roller assembly includes two first rollers 36 corresponding one to one with the first side plates 34. The first rollers 36 are located on the inner side of the first side plate 34. The axis of the first roller 36 is parallel to the first side plate 34. A first roller 37 is coaxially provided inside the first roller 36. The top surface of the first roller 37 is rotatably connected to the first transverse plate 33. The bottom surface of the first roller 37 is rotatably connected to the first fixed plate 35. The top surface of one of the first rollers 37 is connected to a first micro motor 38. The first micro motor 38 is located on the lower surface of the transverse plate.

[0109] Secondly, the second roller assembly includes two second rollers corresponding to the second side plates one by one, the second rollers are located on the inner side of the second side plate, the axis of the second rollers is parallel to the second side plate, and a second roller is coaxially provided inside the second roller. The top surface of the second roller is rotatably connected to the second transverse plate, and the bottom surface of the second roller is rotatably connected to the second fixed plate. The top surface of one of the second rollers is connected to a second micro motor, and the second micro motor is located on the lower surface of the transverse plate. The first micro motor 38 and the second micro motor are electrically connected to the microprocessor respectively.

[0110] In this embodiment, the micromotor model is 260. When the lifting equipment hoists the floating plate to the outside of the I-beam, the second infrared sensor 43 detects the floating plate arrival signal in real time and sends a signal to the microprocessor. Upon receiving the signal, the microprocessor activates the first micromotor 38 and the second micromotor. The activation of the first micromotor 38 rotates the first roller 37 connected to it, which in turn drives the first roller 36 connected to it to roll along the axis of the I-beam, thereby driving the first slider connected to it to move with it. The movement of the first slider also drives the other first roller 36 within it to roll, ensuring smooth and continuous movement of the first slider.

[0111] Similarly, activation of the second micromotor drives the second roller connected to it to rotate, thereby driving the second roller connected to it to roll along the axial direction of the I-beam, thereby driving the second slider connected to it to move accordingly. The movement of the second slider also drives the other first roller 36 within it to roll, ensuring smooth and continuous movement of the second slider. The smooth movement of the first and second sliders drives the movement of the first and second vertical rods 1 and 2, thereby driving the smooth movement of the first and second spray plates 4 and 5.

[0112] In step 2, the first support assembly includes a first telescopic pump 39, which is located on the bottom surface of one of the first fixed plates 35. The free end of the telescopic rod 13 of the first telescopic pump 39 is connected to the first support diagonal rod 40 which is arranged at an angle, and the end of the first support diagonal rod 40 extends diagonally upward.

[0113] Secondly, the second support assembly includes a second telescopic pump 41, which is located on the bottom surface of one of the second fixed plates. The free end of the telescopic rod 13 of the second telescopic pump 41 is connected to a second support diagonal rod 42 that is arranged at an angle. The end of the second support diagonal rod 42 extends diagonally upward. The first telescopic pump 39 and the second telescopic pump 41 are electrically connected to the microprocessor respectively.

[0114] In this embodiment, the microprocessor presets the retraction length required for the telescopic rods 13 of the first and second telescopic pumps 39, 41 to retract when the first and second diagonal support rods 40, 42 contact the bottom of the floating board. When the first and second sliding mechanisms 7, 8 are fully in contact with the floating board, the microprocessor commands the first and second telescopic pumps 39, 41 to activate simultaneously based on the preset retraction length. The telescopic rods 13 of the first and second telescopic pumps 39, 41 retract to the preset retraction length, respectively driving the connected first and second diagonal support rods 40, 42 upward.

[0115] As the first and second diagonal support rods 40 and 42 extend diagonally upward, their ends precisely contact the bottom of the floating slab, forming a stable support structure. This coordinated support effectively shares the weight of the floating slab, significantly reducing the load on the lifting equipment, achieving energy savings and lowering overall construction costs. The entire process is automated through an intelligent control system, ensuring precise and reliable support.

[0116] This embodiment uses a microprocessor to control the movement of the first sliding mechanism 7 and the second sliding mechanism 8, enabling precise positioning of the floating panel and ensuring its accurate installation position. Simultaneously, the microprocessor works in conjunction with the distance sensor 3 and the first infrared sensor 6 to intelligently adjust the spraying patterns of the first and second spray assemblies. Compared to the prior art, this embodiment automatically pours concrete at the connection between the floating panel and the floor slab after the floating panel is positioned. This improves construction efficiency while avoiding the high-altitude work risks associated with manual pouring, significantly enhancing construction safety. Furthermore, the first and second support assemblies support the bottom of the floating panel, effectively sharing its weight and reducing the load on the lifting equipment, achieving energy savings and reducing overall construction costs.
