[0002] At present, the construction of building roof panels usually adopts the following steps: the columns, walls, beams and slabs of the roof layer are cast in one piece, and then the parapet, roof machine room, ventilation duct and other structures are built or concrete walls are constructed on the roof panel body. The construction joint is generally set at the bottom where the slab and the wall meet;

[0003] With this kind of separate construction, once the roof waterproofing layer is damaged, water may seep out from the parapet, causing the surface of the exterior wall to fall off. Water seeping around the ventilation duct may flow into the room, and water seeping from the bottom of the elevator room may enter the elevator pit.

[0004] In the prior art, a Chinese patent document with publication number CN107447903B, a cast-in-place thermal insulation integrated slope roof structure and construction method, raises the problem that the integrity, airtightness and mechanical strength of the traditional slope roof cannot be taken into account at the same time, completely solves the defects such as precipitation leakage and erosion, and has the advantages of being easy to install into an integrated slope roof ridge, simple and firm connection, etc., so as to be more suitable for people's requirements for the slope roof ridge to be firm and waterproof, load-bearing, integrated and beautiful and durable. However, consistent with the traditional method, due to the limitations of the vibration tool, especially in complex structures, it is difficult to fully cover all areas, especially the bottom and corners are often not vibrated enough, resulting in insufficient concrete density in these areas. At the bottom of the roof panel body, if the vibration is insufficient, a honeycomb structure may appear in the concrete, which will affect the overall bearing capacity and durability.

[0018] S1: Accurately lay out and position the roof panel, air duct room, machine room and parapet according to the design drawings to ensure the accuracy of subsequent construction;

[0019] S2: In the area where the lines have been laid out, tie the steel bars of the roof panel body, parapet, air duct room, and machine room as required to ensure that the position and density of the steel bars meet the design specifications;

[0020] S3: According to the design requirements, support the roof panel body, air duct guide wall, machine room guide wall and parapet formwork, embed the water inlet and steel casing with water stop ring, and install the inner and outer formwork;

[0021] S4: The installation component is set below or inside the inner formwork to support the inner formwork and the outer formwork.

[0026] S9: Carry out a roof drainage test to ensure that there is no leakage on the roof. If leakage is found, use the under-slab grouting method to repair the leakage until the leakage problem is solved. Then carry out a water storage test again until it passes the inspection.

[0027] Beneficial effects of the present invention:

[0028] 1. This kind of building roof panel integrated casting structure and casting process, by arranging a rotating rod and a cam in the vibrating assembly, the staggered cams can cover various areas of the inner template, avoiding dead corners during the vibration process, thereby ensuring the uniform density of the concrete in the template, secondly, because the rotational vibration of the cam is automatic and continuous, no human intervention is required, which greatly improves the construction efficiency and reduces the problem of uneven vibration caused by human operation. Finally, the mechanical transmission of the rotating rod and the cam is stable and reliable, and can maintain the stability of the vibration effect for a long time, thereby ensuring the overall quality of the concrete structure. Therefore, the combined design of the rotating rod and the cam not only improves the vibration effect, but also improves the degree of automation and construction quality of the construction.

[0029] 2. The integrated casting structure and casting process of the building roof panel are provided with a floating plate, a connecting rod, a first meshing gear and a second meshing gear in the vibrating assembly. The arc-shaped design of the floating plate enables it to sensitively respond to the flow of concrete, ensuring that it smoothly follows and triggers the vibration action during the rising process of the concrete. The connecting rod is connected to the floating plate. When the floating plate rises, the connecting rod transmits this movement to the lifting rod, thereby driving the meshing gear system at the bottom. The precise transmission of the meshing gear system enables the rotating rod to rotate continuously, driving the cams arranged in an interlaced manner above to continuously hit the inner template, forming a uniform vibration effect. This mechanical transmission design not only realizes the automation of vibration, but also ensures the uniform distribution of vibration, avoiding the dead angle problem in the traditional vibration method. At the same time, the coordinated use of the floating plate and the telescopic plate protects the key components from the intrusion of concrete through the design of the groove and the abutment block, ensuring the stable operation of the vibration system and the compactness of the overall structure. The comprehensive application of this structure significantly improves the quality and construction efficiency of concrete pouring.

[0030] 3. This type of building roof panel integrated casting structure and casting process is equipped with an installation component. The installation component is designed to slide through guide rails and walking wheels, so that the formwork system can be quickly installed and disassembled, greatly improving the construction efficiency. The hydraulic lifting column can accurately adjust the height of the inner formwork to ensure the precise positioning of the formwork and the construction surface, avoiding errors in manual operation. The support and connection of the first pair of tension screws and the second pair of tension screws further enhance the stability and positioning accuracy of the formwork system, effectively avoiding the displacement or loosening of the formwork during the casting process.

The installation assembly is used to support the formwork to ensure its stability during pouring. Then, cast the concrete of the roof panel body 1, parapet, air duct chamber 4 and machine room 6 as a whole. Start the vibrating assembly during the pouring process to ensure the density and uniformity of the concrete. After the concrete pouring is completed, carry out standard maintenance. After reaching the design strength, remove the formwork, and carry out the roof drainage test to ensure that there is no leakage. If there is leakage, use the under-plate grouting method to repair the leakage until it is confirmed that there is no leakage, and then re- A roof water storage test is carried out until it passes the inspection, wherein the parapet guide wall 3, the air duct guide wall 5, the machine room guide wall 7 and the roof panel body 1 are cast as one piece, and a water stop ring steel casing and an exhaust pipe are provided.

[0048] After fixing the guide rail 18 on the bottom layer or bottom surface, the mounting frame 19 is slidably installed above the guide rail 18 through a number of walking wheels 20, and two abutment plates 22 are set below the top of the inner formwork 15 to match the hydraulic lifting columns 21 of the mounting frame 19.

After completing the installation and positioning, the one-piece pouring operation of concrete is carried out. After the pouring is completed, the height of the formwork is adjusted by using the hydraulic lifting columns 21 to facilitate the disassembly of the inner formwork 15 and related components. Finally, the mounting frame 19 is slid out from the guide rail 18 to complete the dismantling of the entire formwork system.

[0049] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10As shown, the vibrating assembly includes a plurality of groups of mounting plates 25 fixedly mounted on the inner side of the inner template 15, each group of mounting plates 25 is provided with four, a rotating rod 26 is rotatably mounted below every two mounting plates 25, a plurality of cams 27 are arranged above the rotating rod 26, and the plurality of cams 27 are arranged in a staggered manner, a threaded hole 17 is provided on the outer surface of the connecting plate 16 or the inner template 15, a positioning ring 29 is provided below the inner part of the threaded hole 17, a threaded sleeve 30 is provided on the side of the positioning ring 29 close to the inner template 15, the threaded sleeve 30 is threadedly connected with the threaded hole 17, a vertical rod 31 is provided above the plurality of threaded holes 17, an internal thread groove 32 is provided at the bottom of the vertical rod 31 to match the threaded sleeve 30, and an internal thread groove 32 is provided at the bottom of the vertical rod 31 Matching with the threaded sleeve 30, both sides of the internal thread groove 32 are provided with a slide groove 33, and the interior of the internal thread groove 32 is movably installed with a lifting rod 35, the bottom end of the lifting rod 35 passes through the positioning ring 29, the side of the rotating rod 26 away from the positioning ring 29 is threadedly connected with the first meshing gear 28, the bottom of the lifting rod 35 is sleeved with a second meshing gear 36 meshing with the two first meshing gears 28, and the inner side of the slide groove 33 is provided with a telescopic plate 34, and the top of the lifting rod 35 is penetrated by a connecting hole 38, and the connecting hole 38 is provided with a thread, and both sides of the lifting rod 35 are provided with a floating plate 37, and the side of the floating plate 37 close to the lifting rod 35 is provided with a threaded rod 39 adapted to the connecting hole 38, and the top of the telescopic plate 34 is located below the threaded rod 39;

[0050] During the concrete pouring process, the inner formwork 15 and related components are first installed in place and fixed on the corresponding supporting structure. As the concrete is poured, the concrete begins to flow in the formwork and gradually rises. The plurality of floating plates 37 fixedly installed on the inner side of the inner formwork 15 will be pushed by the rising concrete and gradually float upward. The rise of the floating plates 37 directly pushes the connected lifting rods 35 to move upward. The upward movement of the lifting rods 35 drives the first meshing gear 28 at the bottom to start rotating. The first meshing gear 28 meshes with the second meshing gears 36 on both sides, thereby driving the rotating rods 26 on both sides to rotate. The rotating rods 26 are equipped with a plurality of staggered cams 27. As the rotating rods 26 rotate, the cams 27 will continuously hit the inner formwork. The inner surface of the plate 15, the vibration generated by the staggered impact is evenly distributed in various parts of the inner template 15, the entire vibration process is driven by the flow of concrete, automatically and continuously, without manual intervention, the structure of the threaded rod 39 and the threaded hole 17, the threaded sleeve 30, and the positioning ring 29 ensures the stability of the lifting rod 35 and the floating plate 37 during the movement, and the slide 33 and the telescopic plate 34 provide additional positioning support, so that the vibration action of the entire system is smooth and efficient, ensuring that the concrete is fully and evenly vibrated during the pouring process, ensuring the density and overall quality of the concrete structure, after the vibration is completed, as the concrete gradually solidifies, the system will stop vibrating and enter the next step of the concrete curing process;

[0051] The bottom of the floating plate 37 is arranged in an arc shape. A groove 40 is provided on one side of the floating plate 37 close to the telescopic plate 34. An abutment block 41 is slidably installed inside the groove 40. A return spring 42 is arranged between the abutment block 41 and the groove 40.

[0052] During the concrete pouring process, as the concrete gradually fills the formwork and begins to flow, the bottom arc surface of the floating plate 37 can smoothly contact and follow the rising concrete, and the abutment block 41 protects the telescopic position of the telescopic plate 34 from being poured by concrete, thereby ensuring the normal use of the telescopic plate 34. When the floating plate 37 rises, it will drive the telescopic plate 34 to rise synchronously to block both sides of the vertical rod 31 to ensure vibration.

[0053] The present application also discloses a building roof panel integrated casting process, which is applied to the above-mentioned building roof panel integrated casting structure, and includes the following steps:

[0054] S1: Accurately lay out and position the roof panel body 1, the air duct chamber 4, the machine room 6 and the parapet according to the design drawings to ensure the accuracy of subsequent construction;

[0055] S2: In the area where the lines have been laid out and positioned, tie the steel bars of the roof panel body 1, parapet, air duct room 4, and machine room 6 as required to ensure that the position and density of the steel bars meet the design specifications;

[0056] S3: According to the design requirements, the roof panel body 1, the air duct guide wall 5, the machine room guide wall 7 and the parapet formwork are supported, the water inlet 2 and the steel casing with the water stop ring are embedded, and the inner formwork 15 and the outer formwork are installed;

[0057] S4: The mounting assembly is arranged below or inside the inner template 15, and is used to support the inner template 15 and the outer template. After the guide rail 18 is fixed on the bottom layer or the bottom surface, it is slidably mounted above the guide rail 18 through the mounting frame 19, and the template height is adjusted by the hydraulic lifting column 21. The top of the template is connected by the first tension screw 23, and the two sides of the inner template 15 are supported by the second tension screw 24 to ensure the stability of the support system;

[0058] S5: Perform an integral pouring operation to integrally pour the concrete of the roof panel body 1, parapet, air duct chamber 4, and machine room 6. During the pouring process, start the vibrating assembly to ensure the density and uniformity of the concrete. The vibrating assembly interlacedly hits the inner surface of the inner template 15 through the cam 27 to generate uniform vibration to ensure that there is no gap in the concrete.

[0059] S6: The vibrating assembly is arranged on the outside of the inner formwork 15. As the concrete flows, the floating plate 37 and the lifting rod 35 rise accordingly, driving the rotating rod 26 to rotate, and then driving the cam 27 to hit the surface of the formwork to achieve automatic vibration. This process ensures the compactness of the concrete structure.

[0060] S7: After the concrete pouring is completed, standard curing is carried out until the concrete reaches the designed strength;

[0061] S8: After the concrete reaches the designed strength, the formwork is removed, and the height of the inner formwork 15 is adjusted by using the hydraulic lifting column 21 to facilitate the removal of the installation components, and the mounting frame 19 is slid out of the guide rail 18 to complete the removal of the entire formwork system;

[0062] S9: Carry out roof drainage test to ensure that there is no leakage on the roof. If leakage is found, use the under-slab grouting method to repair the leakage until the leakage problem is solved. Then carry out water storage test again until it passes the test;

[0063] Compared with the prior art, the automatic vibrating assembly introduced in the overall pouring process ensures the density and uniformity of the concrete in the inner formwork 15 through the staggered impact of the cam 27, especially for the bottom area that is difficult to reach, and effectively avoids the problems of vibration dead angle and uneven density in the traditional vibration method through self-vibration. The automated operation of the vibrating assembly not only improves the construction efficiency and reduces the necessity of manual intervention, but also cooperates with the external vibrating rod to further enhance the upper layer vibration effect of the concrete, ensuring the high quality of the entire pouring process.

6. A building roof panel integrated casting process, applied to the building roof panel integrated casting structure as claimed in claim 5, characterized in that: The following steps are involved: S1: Accurately lay out and position the roof panel body (1), the air duct chamber (4), the machine room (6) and the parapet according to the design drawings to ensure the accuracy of subsequent construction; S2: In the area where the lines have been laid out and positioned, tie the steel bars of the roof panel body (1), parapet, air duct chamber (4), and machine room (6) as required, ensuring that the position and density of the steel bars meet the design specifications; S3: According to the design requirements, the roof panel body (1), the air duct guide wall (5), the machine room guide wall (7) and the parapet formwork are supported, the water inlet (2) and the steel casing with a water stop ring are embedded, and the inner formwork (15) and the outer formwork are installed; S4: The mounting assembly is arranged below or inside the inner template (15) and is used to support the inner template (15) and the outer template. After the guide rail (18) is fixed on the bottom layer or the bottom surface, it is slidably mounted above the guide rail (18) through the mounting frame (19), and the template height is adjusted by using the hydraulic lifting column (21). The top of the template is connected by using the first tensioning screw rod (23), and the two sides of the inner template (15) are supported by the second tensioning screw rod (24) to ensure the stability of the support system; S5: Performing an integral pouring operation to integrally pour the concrete of the roof panel body (1), the parapet, the air duct chamber (4), and the machine room (6) in place. During the pouring process, the vibrating assembly is started to ensure the density and uniformity of the concrete. The vibrating assembly interlacedly strikes the inner surface of the inner template (15) through the cam (27) to generate uniform vibration to ensure that there are no gaps in the concrete. S6: The vibrating assembly is arranged on the outside of the inner formwork (15). As the concrete flows, the floating plate (37) and the lifting rod (35) rise accordingly, driving the rotating rod (26) to rotate, thereby driving the cam (27) to hit the surface of the formwork, thereby achieving automatic vibration. This process ensures the compactness of the concrete structure. S7: After the concrete pouring is completed, standard curing is carried out until the concrete reaches the designed strength; S8: After the concrete reaches the designed strength, the formwork is removed, and the height of the inner formwork (15) is adjusted using the hydraulic lifting column (21) to facilitate the removal of the installation components, and the installation frame (19) is slid out of the guide rail (18), thereby completing the removal of the entire formwork system; S9: Carry out a roof drainage test to ensure that there is no leakage on the roof. If leakage is found, use the under-slab grouting method to repair the leakage until the leakage problem is solved. Then carry out a water storage test again until it passes the inspection.
