Description

Technical Field

[0001] This application relates to the technical field of building engineering, and in particular to a prefabricated inverted roof structure. Background Technology

[0002] To extend the service life of the waterproof layer, the existing roof structure places the water-repellent insulation layer on top of the waterproof layer. The inverted roof structure consists of an insulation layer, a waterproof layer, and a structural layer from top to bottom.

[0003] Compared to the traditional large-area inverted roof construction method, in order to improve construction speed and reduce construction costs, there is now a prefabricated roof structure. This involves manufacturing roof panels in a factory and then transporting them to the roof of the building at the construction site for installation. Therefore, using reliable connection methods for assembly is an important factor in ensuring the stability of the roof structure.

[0004] In the existing precast roof panels, reinforcing bars are pre-embedded on the side of the roof panel during the manufacturing process. One end of the reinforcing bar abuts against the side of the adjacent roof panel, and then concrete is poured into the gap between the two adjacent roof panels to achieve connection. The reinforcing bar can improve the strength of the roof panel connection structure to a certain extent by bearing the force. However, its shear and tensile resistance is not good. The connection is prone to cracks or even misalignment of the two roof panels due to external forces. Summary of the Invention

[0005] In order to improve the poor shear and tensile resistance of prefabricated roof panels, this application provides a prefabricated inverted roof structure.

[0006] This application provides a prefabricated inverted roof structure, which adopts the following technical solution:

[0007] A prefabricated inverted roof structure, comprising:

[0008] Several support frames are arranged parallel to each other at intervals;

[0009] A plurality of connecting mechanisms are arranged parallel to each other and spaced apart along the length of the support frame. Each pair of adjacent connecting mechanisms is connected to two adjacent support frames to form a support frame. Each connecting mechanism includes a fixed frame, a plurality of connecting members, and a pushing member. One end of the fixed frame is fixedly connected to the support frame. The connecting members are movably connected to the fixed frame. Each connecting member includes a connecting plate connected to the fixed frame and a reinforcing plate perpendicular to the connecting plate. The pushing member is movably connected to the fixed frame.

[0010] The roof panel has a connecting groove on its side;

[0011] The connecting mechanism has a positioning state and an installation state. When it is in the positioning state, the connector is closed on the side wall of the fixing frame, and the roof panel can enter the supporting frame. When it is in the installation state, the jacking member drives the reinforcing plate into the connecting groove, and the gap between the connecting mechanism and the roof panel is filled with concrete.

[0012] By adopting the above technical solution, during construction, the support frame is first installed on the roof, and then the connecting mechanism is installed on the support frame to form a support frame. At this time, the connector closes, allowing the roof panel to enter into the support frame. Subsequently, the jacking component acts to push the reinforcing plate into the connecting groove. Finally, concrete is poured into the gap between the roof panel and the connecting mechanism, thereby tightly joining two adjacent roof panels together. The connecting plate and reinforcing plate, which are embedded in the roof panel and perpendicular to each other, can enhance the shear and tensile resistance of the connection. Moreover, by placing the roof panel with the support frame, it can restrict the four sides of the roof panel, thereby reducing the relative sliding of each structural layer in the inverted roof panel, making the overall roof structure more stable, improving safety performance, and enhancing the thermal insulation and waterproofing performance of the building.

[0013] Optionally, the connecting mechanism further includes a movable frame slidably disposed within the fixed frame, and the pushing member is a pushing block disposed on the side wall of the movable frame; the connecting member is hinged to the side wall of the fixed frame, and the side of the connecting member facing the movable frame is set as an inclined surface; when the movable frame slides towards the end where the fixed frame is connected to the support frame, the pushing block abuts against the inclined surface and gradually drives the connecting member to rotate away from the fixed frame.

[0014] By adopting the above technical solution, the jacking component is specifically set on the movable frame. After the roof panel is placed in the support frame, the movable frame can be pushed from one end of the fixed frame. The reinforcing plate can be rotated and pushed into the connecting groove by the cooperation of the inclined surfaces on the jacking component and the connector, making the construction more convenient and faster.

[0015] Optionally, the roof panel has pre-embedded reinforcing bars in the connecting groove, and when the connector is in the installation state, the side of the reinforcing plate facing the movable frame abuts against the reinforcing bars.

[0016] By adopting the above technical solutions, the reinforcement bars and reinforcing plates inside the roof panels can be connected in a way that further improves the tensile strength of the roof panel connections, making the prefabricated inverted roof structure more stable.

[0017] Optionally, the connector is connected to a first elastic element that causes the connector to close against the side wall of the fixing frame.

[0018] By adopting the above technical solution, the first elastic element can restrict the connector from unfolding away from the fixed frame, thereby making the connecting mechanism stably positioned, facilitating the roof panel to enter the supporting frame, and reducing the possibility of reduced construction efficiency due to the connector possibly unfolding.

[0019] Optionally, the connecting mechanism further includes a driving member, which is threadedly connected to the end of the fixed frame away from the end connected to the support frame, and the driving member abuts against the movable frame.

[0020] By adopting the above technical solution, the drive component that is threaded to the inner wall of one end of the fixed frame can not only restrict the movable frame from detaching from the fixed frame, but also push the movable frame to slide when the drive component is rotated to move into the fixed frame, thereby unfolding the connecting component through the pusher component and making the connecting mechanism into the installation state.

[0021] Optionally, the driving component is fitted with a rotating component, the two ends of which abut against the end face of the fixed frame and the side face of the support frame, respectively. A limit strip is provided at the end of the driving component away from the fixed frame, and a limit groove is provided on the inner wall of the rotating component for the limit strip to slide.

[0022] By adopting the above technical solution, the support frame structure can be made more stable by having one end of the fixed frame and one end of the rotating component abut against two adjacent support frames respectively. In addition, when the rotating component is rotated, the limiting strip that is engaged in the limiting groove can drive the driving component to rotate. The other end of the driving component is threadedly connected to the fixed frame, so it can move along the length direction of the fixed frame and finally unfold the connecting component.

[0023] Optionally, the movable frame is connected to a second elastic element that drives the movable frame to slide in the direction of the driving member.

[0024] By adopting the above technical solution, the second elastic member can press the movable frame against the driving member, reducing the possibility of the movable frame sliding in the fixed frame before the roof panel is placed.

[0025] Optionally, the support frame has a water channel along its length, the movable frame has a water inlet hole communicating with the water channel, the top surface of the fixed frame is provided with a water outlet pipe, and the movable frame has a water outlet hole corresponding to the position of the water outlet pipe when in the installation state.

[0026] By adopting the above technical solution, the support frame and the movable frame are connected to a water supply channel. Water flows from inside the support frame into the movable frame and then sprays out through the water outlet pipe on the fixed frame, which can clean the roof panels without people having to climb onto the roof to clean them, making the operation more convenient and safer.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. During construction, the support frame and connecting mechanism are first installed to form a support frame for pre-positioning the roof panel. The roof panel is placed in the support frame. Then, the rotating part is rotated to drive the connecting part into the connecting groove. Finally, concrete is poured into the gap between the roof panel and the connecting mechanism to tightly join the two adjacent roof panels together. The construction is convenient and quick.

[0029] 2. By using connecting plates and reinforcing plates embedded in the roof panel and perpendicular to each other, as well as the rebar embedded in the roof panel and abutting against the reinforcing plate, the shear and tensile resistance of the connection can be enhanced, making the prefabricated inverted roof structure more stable.

[0030] 3. The support frame formed by the installation of the support frame and connecting mechanism can restrict the four sides of the roof panel, thereby reducing the relative sliding of each structural layer in the inverted roof panel, making the overall roof structure more stable, improving safety performance, and enhancing the thermal insulation and waterproofing performance of the house.

[0031] 4. Water flows through the support frame into the movable frame, and then sprays out through the water outlet pipe on the fixed frame, which can clean the roof panels without people having to climb onto the roof to clean them, making the operation more convenient and safer.

[0043] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0044] Example 1:

[0045] Reference Figure 1 This application discloses a prefabricated inverted roof structure, including a roof panel 3, a plurality of support frames 1 arranged in parallel and spaced apart, and a plurality of connecting mechanisms 2 arranged in parallel and spaced apart along the length of the support frames 1; the two ends of two adjacent connecting mechanisms 2 are respectively connected to the two opposite sides of two adjacent support frames 1 to form a support frame 4, the roof panel 3 is installed in the support frame 4, and the gap between the support frame 4 and the roof panel 3 is filled with concrete for reinforcement.

[0046] The roof panel 3 is a prefabricated inverted roof panel 3. The roof panel 3 has a layered structure from bottom to top, consisting of a structural layer, a slope-finding layer, a leveling layer, a waterproof layer, a thermal insulation layer, and a protective layer. The materials of each layer are manufactured in accordance with existing building design standards and specifications, which are well-known technologies, so they will not be described in detail.

[0047] Reference Figure 2 and Figure 3The bottom surface of the support frame 1 extends into support portions 101 on both sides; the connecting mechanism 2 includes a fixing frame 5, one end of which rests on the support portion 101 and can be fixedly connected to the support frame 1 by bolts. The fixing frame 5 can be cylindrical or square column-shaped, and in this embodiment, it is preferably square column-shaped. The bottom surface of the fixing frame 5 extends into support edges 52 on both sides along the length direction. The bottom surface of the roof panel 3 has strip grooves on the four sides that are adapted to the support portion 101 and the support edges 52 so that the roof panel 3 can be pre-placed on the support frame 4.

[0048] Reference Figures 4 to 6 After the roof panel 3 is pre-placed on the supporting frame 4, it needs to be fixedly connected. Several connectors 6 and pushing members 7 are movably connected to the fixing frame 5. The connectors 6 include a connecting plate 61 connected to the fixing frame 5 and a reinforcing plate 62 perpendicular to the connecting plate 61 to improve the shear and tensile resistance of the connection structure. The roof panel 3 has a connecting groove 31 on its side. It should be noted that the connecting mechanism 2 has a positioning state and an installation state. In the positioning state, the connectors 6 are closed within the side wall of the fixing frame 5, and the roof panel 3 can enter and be erected within the supporting frame 4. In the installation state, the pushing member 7 drives the reinforcing plate 62 into the connecting groove 31, and concrete fills the gap between the connecting mechanism 2 and the roof panel 3.

[0049] Specifically, the fixing frame 5 has a cylindrical movable groove, as shown in the figure. Figure 6 and Figure 7 The connecting mechanism 2 also includes a movable frame 8 slidably disposed within the movable slot, and a pushing member 7, which is a pushing block disposed on the side wall of the movable frame 8; the connecting member 6 is hinged to the side wall of the fixed frame 5 via a pivot, and the side of the connecting member 6 facing the movable frame 8 is configured as an inclined surface 63. A limiting part can be provided between the fixed frame 5 and the movable frame 8 to restrict the rotation of the movable frame 8, thereby enabling the pushing member 7 to stably push the connecting member 6. The fixed frame 5 can be configured as a structure of being spliced ​​in half along its length to facilitate the installation of the internal movable frame 8.

[0050] When in the positioning state, the connector 6 is closed on the side wall of the fixed frame 5. In order to make the connecting mechanism 2 stably in the positioning state so that the roof panel 3 can enter the support frame 4, the connector 6 is also connected to a first elastic element 9 that drives the connector 6 to close on the side wall of the fixed frame 5. The first elastic element 9 is a torsion spring sleeved on the rotating shaft. When changing from the positioning state to the installation state, the movable frame 8 is slid towards the end where the fixed frame 5 is connected to the support frame 1. The push block abuts against the inclined surface 63 and gradually drives the connector 6 to rotate away from the fixed frame 5. The bottom of the inclined surface 63 extends out to form a plane to increase the contact area with the push block, so that the connector 6 can be stably in the installation state when pouring concrete later.

[0051] Reference Figure 8In order to further improve the tensile strength of the roof panel 3 connection, the roof panel 3 has embedded rebars 32 in the upper and lower groove walls of the connecting groove 31. A gap is left between the two rebars 32 for the connecting plate 61 to pass through. When the connector 6 is in the installation state, the side of the reinforcing plate 62 facing the movable frame 8 abuts against the rebars 32.

[0052] Furthermore, refer to Figure 9 The connecting mechanism 2 also includes a drive assembly for pushing the movable frame 8. The drive assembly includes a drive member 10 connected within the fixed frame 5 and a rotating member 12 sleeved outside the drive member 10. It should be noted that, in order to facilitate the operation of the drive assembly and thus control the movable frame 8, the length of the fixed frame 5 is less than the distance between two adjacent support frames 1, and the two ends of the rotating member 12 abut against the end face of the fixed frame 5 away from the support frame 1 and the side face of the support frame 1, respectively.

[0053] The outer surface of the driving component 10 is provided with external threads, and the inner wall of the fixed frame 5 is provided with internal threads that mate with the external threads. The driving component 10 is threadedly connected to the fixed frame 5, and one end of the driving component 10 extending into the fixed frame 5 abuts against the movable frame 8. A limit strip 11 is provided at the end of the driving component 10 away from the fixed frame 5, and a limit groove 121 is provided on the inner wall of the rotating component 12 for the limit strip 11 to slide. Several insertion holes for inserting tools can be provided on the outer surface of the rotating component 12, so that the construction personnel can operate the tools to form a lever to rotate the rotating component 12, which is more labor-saving. When the rotating component 12 is rotated, the limit strip 11, which is engaged in the limit groove 121, can drive the driving component 10 to rotate. The other end of the driving component 10 is threadedly connected to the fixed frame 5, so it can move along the length of the fixed frame 5, and finally push the connecting component 6 to unfold.

[0054] In a preferred embodiment, the movable frame 8 is connected to a second elastic member 13 that drives the movable frame 8 to slide towards the driving member 10. The second elastic member 13 can be configured as a spring or a rubber pad. The second elastic member 13 presses the movable frame 8 against the driving member 10, thereby reducing the possibility that the movable frame 8 will slide within the fixed frame 5 and cause the connecting member 6 to unfold before the roof panel 3 is placed.

[0055] Additionally, refer to Figure 3Because the roof is located on the top of the building, it easily accumulates dust and other dirt, so it is necessary to facilitate roof cleaning. A water channel 102 is also provided along the length of the support frame 1, and a branch channel 103 is provided at the connection between the support frame 1 and the rotating component 12. The rotating component 12, the driving component 10, and the movable frame 8 are all hollow. The movable frame 8 has a water inlet hole, and the branch channel 103 connects to the water inlet hole through the rotating component 12 and the driving component 10. A water outlet pipe 51 is provided on the top surface of the fixed frame 5, and a water outlet hole 81 corresponding to the position of the water outlet pipe 51 is provided on the movable frame 8 when it is in the installed state. A nozzle 14 is connected to the water outlet pipe 51, and an external water pipe is connected to the water channel 102 of the support frame 1. Finally, water is sprayed from the nozzle 14 to clean the surface of the roof panel 3. Sealing gaskets are provided at all pipe connections to prevent leakage.

[0056] Optional but not limited, a water outlet pipe 51 can be pre-embedded in the insulation layer of the roof panel 3. The water outlet pipe 51 is connected to the movable frame 8 through an adapter pipe, which can drain water from the inside of the roof panel 3, improve the service life of the insulation layer, and recycle the drained water for cleaning the roof, making it more environmentally friendly.

[0057] The implementation principle of Embodiment 1 of this application is as follows:

[0058] During construction, the support frame 1 is first installed on the roof, and then the connecting mechanism 2 is installed on the support frame 1 to form a support frame 4. At this time, the connecting piece 6 is driven to close by the first elastic member 9, allowing the roof panel 3 to enter the support frame 4. Then, the rotating member 12 is rotated to drive the driving member 10 to rotate. The other end of the driving member 10 is threadedly connected to the fixed frame 5, so that it can move along the length direction of the fixed frame 5. The driving member 10 pushes the movable frame 8, and the pushing member 7 on the movable frame 8 abuts against the inclined surface 63 of the connecting piece 6, finally unfolding the connecting piece 6 into the connecting groove 31. Finally, concrete is poured into the gap between the roof panel 3 and the connecting mechanism 2, so that the two adjacent roof panels 3 are tightly joined together.

[0059] Example 2:

[0060] Reference Figure 10 The difference between this embodiment and embodiment 1 lies in the structural arrangement of the pusher 7 and the connector 6, as well as the connection structure between the pusher 7 and the connector 6. The pusher 7 is a pusher block disposed on the movable frame 8. A rack 71 is disposed along the length direction of the movable frame 8 on the surface of the pusher block. A gear 64 that meshes with the rack 71 is disposed at the end of the connector 6 that is hinged to the mounting frame.

[0061] The implementation principle of Embodiment 2 of this application is as follows:

[0062] When the movable frame 8 slides, the connector 6 can be unfolded into the connecting groove 31 of the roof panel 3 through the cooperation of the rack 71 and the gear 64.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
