[0002] Prefabricated buildings are quick to construct and have low production costs, leading to their rapid global adoption. Early prefabricated buildings were often monotonous and lacked variety. Later, design improvements increased flexibility and diversity, enabling mass production and a wider range of styles. The combination of prefabricated slabs and cast-in-place layers is a key technology in prefabricated construction, with demands primarily focused on optimizing structural performance, improving construction efficiency, and functional adaptability. The prefabricated slabs, through the collaborative work of the prefabricated panels and cast-in-place layers, form an integrated load-bearing system, significantly improving the building's rigidity and seismic performance. The interface between the cast-in-place layer and the prefabricated slab needs to be roughened (with a depth ≥ 4mm), and an interface agent needs to be applied to the surface of the prefabricated slab to enhance adhesion. However, the current interface agent application process involves workers using hand-held rollers to apply the interface agent to various parts of the prefabricated slab surface. After each section is coated, workers need to repeatedly apply more interface agent with the rollers, a time-consuming and labor-intensive process that increases workload and reduces efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0019] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0020] A connection structure for composite slab construction includes a base 1, an electric telescopic rod 2 mounted on one top end of the base 1, a first adjusting seat 3 mounted on the top end of the electric telescopic rod 2, a storage box 5 mounted on the top end of the first adjusting seat 3, a connecting rod mounted on one end of the outer wall of the storage box 5, and a conveying brush mechanism mounted on the connecting rod and the storage box 5. The conveying brush mechanism includes an extension adjustment component, a roller brush component, and a conveying component. The extension adjustment component is used to adjust the position of the roller brush component, the conveying component is used to spray an interface agent onto the roller brush component, and the roller brush component is used to brush the interface agent onto the composite slab. In use, the position of the roller brush component can be adjusted by the extension adjustment component, the interface agent can be sprayed onto the roller brush component by the conveying component, and the interface agent can be brushed onto the composite slab by the roller brush component. The structure is simple and easy to operate, eliminating the need for workers to manually repeatedly dip and apply interface agent to various parts of the bonding surface, reducing the workload of workers and further improving work efficiency.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the conveying assembly includes a branch pipe 12 embedded inside the fixed cover 11. The branch pipe 12 has a Y-shaped cross-section. A corrugated pipe 13 extending into the storage tank 5 is installed at the top of the branch pipe 12. Electric nozzles 14 are installed at both ends of the bottom of the branch pipe 12. An observation window is embedded on one side of the outer wall of the storage tank 5. A filling hopper 15 is embedded at the top of the storage tank 5. A sealing cover is locked to the top of the filling hopper 15. First, the operator can unlock the locking device in advance to remove the sealing cover, and then fill the interface agent into the inside of the storage tank 5 through the filling hopper 15. The interface agent is poured into the inside of the branch pipe 12 along the corrugated pipe 13. When it is necessary to add interface agent, the electric nozzles 14 can be turned on to spray the interface agent onto the surface of the roller brush 20.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the extension adjustment assembly includes a second motor mounted on one end of a connecting rod. An extension seat 6 is mounted on one side of the second motor. The extension seat 6 has a T-shaped cross-section. A second adjustment groove is formed at one top end of the extension seat 6. A second threaded rod 7 is rotatably connected to the inner side of the second adjustment groove. The drive end of the second motor extends into the inner side of the second adjustment groove and is fixedly connected to one end of the second threaded rod 7. An extension frame 8 is threadedly connected to the outer side of the second threaded rod 7. The extension frame 8 is slidably connected to the second adjustment groove. Linkage plates 9 are rotatably connected to both ends of the bottom of the extension frame 8. A sliding groove is formed at the other end of the extension seat 6. Two sets of sliding rods 10 are slidably connected to the inner side of the sliding groove. One end of each sliding rod 10 is rotatably connected to one side of the linkage plate 9. The other end is equipped with a fixed cover 11. After the spraying is completed, the base 1 can be moved to the composite plate. Depending on the size of the interval between the truss steel bars on the composite plate of different specifications, the operator can start the second motor to rotate forward or backward to drive the second threaded rod 7 to rotate, so that the extension frame 8 slides inside the second adjustment groove, thereby pulling the two sets of linkage plates 9 and sliding rods 10 to deflect. When the angle of the linkage plate 9 changes, it will also pull the sliding rod 10 to slide inside the sliding groove, thereby driving the fixed cover 11 at its bottom to move, so that the two sets of roller brushes 20 adjust the coating position according to the size of the interval between the truss steel bars on the composite plate, and at the same time coat the area between two adjacent sets of truss steel bars on the composite plate.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the buffer roller brush assembly includes connecting frames 16 installed on both sides of the outer wall of the fixed cover 11. The connecting frame 16 has an L-shaped cross-section. One end of the connecting frame 16 has a synchronization groove. A synchronization rod 17 is slidably connected to the inner side of the synchronization groove. An avoidance spring 18 is installed between the outer wall of the synchronization rod 17 and the inner wall of the synchronization groove. Side plates 19 are installed at both ends of the synchronization rod 17. A roller brush 20 is rotatably connected between the two sets of side plates 19. Further, the electric telescopic rod 2 is then activated to drive the storage box 5 and the conveying brush wiping mechanism on the connecting rod to move downward, so that the roller brush 20 approaches the surface of the composite plate. When the electric telescopic rod 2 descends too quickly and too much, the roller brush 20 can drive the side plates 19 and the synchronization rod 17 to move upward after contacting the surface of the composite plate, so that the synchronization rod 17 squeezes the avoidance spring 18 inside the synchronization groove, thus preventing the roller brush 20 from colliding and squeezing with the composite plate when it descends too quickly and too much, causing deformation and damage to the components or the composite plate.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the top of the first adjusting seat 3 is provided with a first adjusting groove. The inner side of the first adjusting groove is rotatably connected to a first threaded rod 4. The outer side of the first threaded rod 4 is threadedly connected to a first adjusting block. The first adjusting block and the first adjusting groove are slidably connected. A first motor is installed at one end of the first adjusting seat 3. The drive end of the first motor extends to the inner side of the first adjusting groove and is fixedly connected to one end of the first threaded rod 4. Furthermore, when the first motor is started to rotate forward or reverse, it can drive the first threaded rod 4 to rotate, causing the first adjusting block to slide inside the first adjusting groove, thereby driving the connecting rod and the two sets of roller brushes 20 to perform coating and brushing operations. After the brushing is completed, the composite plate can be left to stand for one hour before being hoisted to the designated position, waiting for the workers to pour the cast-in-place layer.

[0025] The implementation principle of the connection structure for composite slab construction in this application embodiment is as follows: Workers can unfasten the lock and remove the sealing cap in advance, then pour the interface agent into the storage tank 5 through the filling hopper 15. The interface agent is poured into the branch pipe 12 along the corrugated pipe 13. When interface agent needs to be added, the electric spray head 14 can be turned on to spray the interface agent onto the surface of the roller brush 20. After spraying, the base 1 can be moved to the composite slab. Depending on the spacing between the truss steel bars on the composite slab of different specifications, the worker can start the second motor to rotate forward or backward, driving the second threaded rod 7 to rotate, causing the extension frame 8 to slide inside the second adjustment groove, thereby pulling the two sets of linkage plates 9 and sliding rods 10 to deflect. When the angle of the linkage plate 9 changes, it also pulls the sliding rod 10 to slide inside the sliding groove, thereby driving the fixed cover 11 at its bottom to move, so that the two sets of roller brushes 20 can be adjusted according to the spacing between the truss steel bars on the composite slab. The application position is adjusted by the interval size, and the area between two adjacent sets of truss steel bars on the composite slab is coated. Then, the electric telescopic rod 2 is activated to drive the storage box 5 and the conveying brush mechanism on the connecting rod to move down, so that the roller brush 20 is close to the surface of the composite slab. When the electric telescopic rod 2 descends too fast or too far, the roller brush 20 can drive the side plate 19 and the synchronous rod 17 to move up after contacting the surface of the composite slab. This causes the synchronous rod 17 to squeeze the avoidance spring 18 inside the synchronous groove, so as to avoid the roller brush 20 from colliding and squeezing with the composite slab when it descends too fast or too far, causing deformation or damage to the components or the composite slab. Then, the first motor is started to rotate forward or reverse, which can drive the first threaded rod 4 to rotate, so that the first adjusting block slides inside the first adjusting groove, thereby driving the connecting rod and the two sets of roller brushes 20 to perform the coating and brushing operation. After the brushing is completed, the composite slab can be left to stand for one hour before being hoisted to the designated position, waiting for the workers to pour the cast-in-place layer.

[0026] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
