Description

Technical Field

[0001] This invention belongs to the technical field of large prefabricated roof panels in building engineering, and relates to a sealing treatment structure for splicing large prefabricated roof panels. Background Technology

[0002] Large precast roof panels refer to roof components that are precast in a factory and are relatively large in size (the area of ​​a single panel is usually ≥10 ㎡), and are assembled on-site to form the roof structure. Based on differences in materials and construction, they are mainly divided into: reinforced concrete precast roof panels, lightweight concrete precast roof panels, and composite material precast roof panels. Large precast roof panels are widely used due to their advantages such as high construction efficiency and low cost.

[0003] Chinese utility model patent CN215670568U discloses a fully prefabricated roof panel and its connection nodes, including a roof panel with a roof beam on its bottom surface, and the roof panel and the roof beam are prefabricated integrally. A first tongue-and-groove joint is provided at the joint of the roof panel, and a protruding reinforcing bar is embedded in the first tongue-and-groove joint. A ring beam is provided at the connection between the roof panel and the outer wall, and a second tongue-and-groove joint with a higher inner surface and a lower outer surface is provided at the bottom of the ring beam. When the fully prefabricated roof panels are spliced ​​together, a first connecting reinforcing bar is lapped between the protruding reinforcing bars of the spliced ​​fully prefabricated roof panels, and each first connecting reinforcing bar is tied to a second connecting reinforcing bar to form a whole, and the splice joint is filled with cast-in-place concrete. The fully prefabricated roof panel is connected to the wall through the tongue-and-groove joint, and a continuous reinforcing bar is provided between the fully prefabricated roof panel and the wall and filled with mortar. Chinese invention patent CN118087796A discloses a waterproof structure and construction method for prefabricated roof joints, including prefabricated roof panels and a waterproof sealing component disposed between two adjacent roof panels. One side of the roof panel has a positioning groove, and the other side of the roof panel has a positioning block corresponding to the positioning groove. The waterproof sealing component includes sealing strips spaced apart within the positioning groove, with a mating space formed between the two sealing strips. The bottom of the positioning block has a sealing block inserted into the mating space, and elastic elements are provided on both sides of the sealing block. When the sealing block enters the mating space, the elastic elements drive the sealing strips to fill the gap between the two roof panels. Chinese invention patent CN113293907A discloses a prefabricated pitched roof structure and its construction method, comprising two pitched roof bodies, the top ends of which are joined together to form a ridge; L-shaped beams are respectively provided at the upper and lower ends of the pitched roof bodies, the upper end of the L-shaped beams is fixed to the end of the pitched roof body, and the lower end extends vertically and is fixed to a column; wherein, the L-shaped beams at the top of the two pitched roof bodies are spliced ​​together to form a ridge beam, and the lower end of the ridge beam is fixedly connected to a first column through a prefabricated groove beam; the L-shaped beam at the lower end of the pitched roof body is fixedly connected to a second column; the invention provides L-shaped beams at both ends of the pitched roof body, the L-shaped beams at the upper ends of the two pitched roof bodies that are joined together to form a ridge beam, the ridge beam is fixed to a column through a prefabricated groove beam, and the L-shaped beam at the lower end is fixedly connected to a column; However, existing precast roof panels typically rely on the compression deformation of elastic sealing strips to fill the joints during use, and apply pre-tightening force through bolts and pressure plates to ensure that the sealing strips are tightly fitted to the roof panels. However, the installation process for precast roof panels with this structure is cumbersome, and it is difficult for two precast roof panels to generate compressive force between each other, resulting in poor sealing performance. Therefore, we propose a large precast roof panel splicing and sealing treatment structure. Summary of the Invention

[0004] To address the problems of cumbersome installation procedures and poor sealing caused by the difficulty in generating compressive force between two precast roof panels during use, this invention proposes a large precast roof panel splicing and sealing structure. This structure effectively solves the problems of cumbersome installation procedures and poor sealing caused by the difficulty in generating compressive force between two precast roof panels during use.

[0006] Furthermore, the connecting assembly includes a fixing bracket slidably connected within the mounting groove. The fixing bracket is C-shaped, and the mounting groove has a protrusion that contacts the inner side of the fixing bracket to prevent the fixing bracket from detaching from the mounting groove. Both ends of the fixing bracket extend out of the mounting groove, and two fixing heads are symmetrically arranged at both ends of the fixing bracket. The fixing heads are triangular, and the inclined surfaces of the fixing heads slope downwards away from the mounting groove. The fixing heads can slide into the connecting lock groove along with the fixing bracket. The front side of the roof panel body is provided with multiple sets of pushing components for pushing the fixing bracket to slide. The upper and lower sides of the connecting lock groove are symmetrically arranged with fixing components to prevent the fixing heads from moving within the connecting lock groove.

[0007] Furthermore, the pushing component includes a fixing lock groove formed on the front side of the roof panel body, the fixing lock groove is connected to the innermost end of the mounting groove, a fixing lock block is provided in the fixing lock groove, the side of the fixing lock block is an inclined surface from top to bottom, and the fixing lock block is a solid structure.

[0008] Furthermore, the fixing component includes a limiting lock groove formed on the upper and lower sides of the connecting lock groove, a limiting lock block is slidably connected in the limiting lock groove, one end of the limiting lock block extends into the connecting lock groove, the end of the limiting lock block in the connecting lock groove is an inclined surface opposite to the fixing block, and an elastic component is provided in the limiting lock groove to push the limiting lock block to move into the connecting lock groove.

[0009] Furthermore, the elastic component includes a plug-in post disposed in the limiting lock groove and a spring sleeved on the plug-in post. The side of the limiting lock block away from the connecting lock groove has a plug-in groove, in which the limiting post is inserted. The two ends of the spring abut against the inner side of the limiting lock groove and the rear side of the limiting lock block, respectively.

[0012] Furthermore, the roof panel body has two fixing frames on its side, one at the front and one at the back. The fixing frames are made of rubber and have a smooth surface.

[0013] Furthermore, the fixing frame is made of metal and is capable of elastic deformation, with the outer width of the fixing frame matching the inner width of the mounting groove.

[0014] Furthermore, the main body of the roof panel has a rectangular structure and is made of concrete.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] like Figures 1 to 4 As shown, a large prefabricated roof panel splicing and sealing structure includes a roof panel body 1. The roof panel body 1 has two mounting grooves 3 on its upper and right sides. The roof panel body 1 has two connecting slots 8 on its left and lower sides, corresponding to the positions of the mounting grooves 3. The roof panel body 1 has a connecting lock groove 9 that communicates with the connecting slots 8. The mounting grooves 3 are provided with connecting components that can be fixedly inserted into the connecting lock grooves 9.

[0020] In this embodiment, the connecting component includes a fixing frame 4 slidably connected in the mounting groove 3. The fixing frame 4 is "C-shaped". The mounting groove 3 has a protrusion that contacts the inner side of the fixing frame 4 so that the fixing frame 4 cannot be disengaged from the mounting groove 3. Both ends of the fixing frame 4 extend out of the mounting groove 3, and two fixing heads 5 are symmetrically arranged at both ends of the fixing frame 4. The fixing heads 5 are triangular, and the inclined surface of the fixing heads 5 is inclined downward in the direction away from the mounting groove 3. The fixing heads 5 can slide into the connecting locking groove 9 with the fixing frame 4. The front side of the roof panel body 1 is provided with multiple sets of pushing components for pushing the fixing frame 4 to slide.

[0021] In this embodiment, the pushing component includes a fixing groove 6 formed on the front side of the roof panel body 1. The fixing groove 6 is connected to the innermost end of the mounting groove 3. A fixing block 7 is provided in the fixing groove 6. The side of the fixing block 7 is an inclined surface that slopes from top to bottom, and the fixing block 7 is a solid structure.

[0022] In this embodiment, the roof panel body 1 is provided with two fixing frames on the side, front and back. The fixing frames are made of rubber material and have a smooth surface. The fixing frames 2, made of rubber material, can play a deformation role and can fill the gaps between the roof panel bodies 1 after being squeezed.

[0023] In this embodiment, the fixing frame 4 is made of metal and is capable of elastic deformation. The outer width of the fixing frame 4 is consistent with the inner width of the mounting groove 3. The fixing frame 4, which is made of metal, is not easily damaged.

[0024] In this embodiment, the roof panel body 1 is a rectangular structure, and the roof panel body 1 is made of concrete material, making the roof panel body 1 more robust and durable.

[0025] When using the above embodiments: Workers placed the first roof panel body 1 in the designated installation position and secured it. After the first roof panel body 1 was installed, workers placed the second roof panel body 1 to one side of the first roof panel body 1, aligning the fixing bracket 4 of the first roof panel body 1 with the connecting slot 8 of the second roof panel body 1. Then, workers pushed the second roof panel body 1 closer to fit against the first roof panel body 1, allowing the fixing head 5 of the first roof panel body 1 to be inserted into the connecting slot 8. Next, workers inserted the fixing locking block 7 into the fixing locking groove 6 and used a tool to tap the fixing locking block 7. When the fixing locking block 7 entered the fixing locking groove 6, the inclined surface of the fixing locking block 7 could... The fixing frame 4 is able to move towards the connecting lock groove 9. As the fixing frame 4 moves, it can drive the fixing head 5 to engage in the connecting lock groove 9. The worker continues to use tools to tap the fixing lock block 7 into the fixing lock groove 6. At this time, the fixing frame 4 can pull the second roof panel body 1 closer to the first roof panel body 1 under the action of the fixing head 5. At the same time, the fixing frame 2 between the two roof panel bodies 1 can deform and fill the gap, ensuring the seal between the two roof panel bodies 1. At this time, the installation is completed. This prefabricated roof panel splicing and sealing device with this structure not only simplifies the installation steps, but also allows the prefabricated roof panels to form mutual compressive force after splicing, thus improving the sealing effect.

[0026] Preferably, after the worker taps the locking block 7 into the locking groove 6, the worker can fill the gap between the locking block 7 and the locking groove 6 with sealant or expanding glue to seal and fix it. At the same time, the locking block 7 and the locking groove 6 can be connected and fixed by common fixing structures such as bolts to prevent the locking block 7 from falling out of the locking groove 6, thus ensuring the sealing effect and reliability of the device during use.

[0027] The above embodiment achieves rapid installation of adjacent roof panel bodies 1 through the setting of fixing frame 4, fixing head 5, fixing lock groove 6, fixing lock block 7, connecting slot 8 and connecting lock groove 9, which improves the convenience of workers when installing roof panel bodies 1. At the same time, the fixing frame 2 squeezes each other to fill the gap between two adjacent roof panel bodies 1, which improves the sealing effect between adjacent roof panel bodies 1.

[0028] Example 2 differs from Example 1 in that: like Figure 5As shown, in this embodiment, the upper and lower sides of the connecting lock groove 9 are symmetrically arranged with fixing components to prevent the fixing head 5 from moving within the connecting lock groove 9. The fixing components include limiting lock grooves 13 formed on the upper and lower sides of the connecting lock groove 9. A limiting lock block 14 is slidably connected within the limiting lock groove 13. One end of the limiting lock block 14 extends into the connecting lock groove 9. The end of the limiting lock block 14 located within the connecting lock groove 9 is an inclined surface opposite to the fixing block. An elastic component is provided within the limiting lock groove 13 to push the limiting lock block 14 to move towards the connecting lock groove 9. The elastic component includes a plug-in post 15 provided within the limiting lock groove 13 and a spring 16 sleeved on the plug-in post 15. A plug-in groove is formed on the side of the limiting lock block 14 away from the connecting lock groove 9. A limiting post is inserted into the plug-in groove. The two ends of the spring 16 abut against the inner side of the limiting lock groove 13 and the rear side of the limiting lock block 14, respectively. In the above embodiment, when the fixing head 5 moves into the connecting lock groove 9, the inclined surface of the fixing head 5 contacts the inclined surface of the limiting lock block 14. While moving, the fixing head 5 can push the limiting lock block 14 into the limiting lock groove 13. When the fixing head 5 is fully inserted into the connecting lock groove 9, the inclined surface of the fixing head 5 does not contact the inclined surface of the limiting lock block 14. Under the action of the spring 16, the limiting lock block 14 extends out of the fixing lock groove 6. At this time, the limiting lock block 14 contacts the opposite side of the fixing head 5, so that the fixing head 5 cannot move in the connecting lock groove 9, ensuring the connection effect of the two adjacent roof panel bodies 1, preventing the gap between the two adjacent roof panel bodies 1 from widening due to the loosening of the fixing lock block 7, and further ensuring the reliability and sealing of the connection between the two adjacent roof panel bodies 1.

[0029] Example 3 differs from Example 1 in that: like Figure 6 and Figure 7 As shown, in this embodiment, the left and right sides of the roof panel body 1 are respectively provided with fixing blocks 11 and fixing slots 10. The fixing blocks 11 can be inserted into the fixing slots 10 of the adjacent roof panel body 1. The fixing blocks 11 are hollow structures, and a grouting hole 12 is provided between the fixing blocks 11 and the fixing slots 10 for communication.

[0030] In this embodiment, the fixed insert 11 has multiple slurry outlet holes 17 through its side.

[0031] In use, when two adjacent roof panel bodies 1 are connected, the fixing block 11 of the first roof panel body 1 can be inserted into the fixing slot 10. Then, the workers can inject expanding sealant into the roof panel body 1 through the grouting hole 12 in the fixing hole. The expanding sealant can enter the fixing block 11 through the grouting hole 12 and overflow through the grout outlet hole 17 on the fixing block 11 to fill the gap between the fixing block 11 and the fixing slot 10, thereby improving the connection strength and sealing effect when the two adjacent roof panel bodies 1 are connected. Since the grouting hole 12 is connected to the fixing hole, when the worker injects grout into the grouting hole 12 of a roof panel body 1, the expanding sealant can flow through the connected grouting hole 12 to the fixing blocks 11 of a row of roof panel bodies 1, which improves the convenience of the worker when grouting and connecting adjacent roof panel bodies 1 and improves the work efficiency of the worker when fixing and installing the roof panel bodies 1.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
