Description

Technical Field

[0001] This invention relates to the field of building engineering, specifically to a new type of prefabricated panel that is easy to move and assemble. Background Technology

[0002] The most common type of floor slab in prefabricated concrete structures in the construction industry is the truss reinforced concrete composite slab. It is fixed to the support with steel bars, and finally concrete is poured in the space to be poured between the support and one or more spliced ​​composite slabs. Currently, prefabricated spliced ​​composite floor slabs are manufactured in the factory and transported to the installation site by transport vehicles. The floor slabs are then fixed and connected by cement pouring. Currently, the splicing between composite slabs is usually done by inserting and binding steel bars. This traditional connection method has low load-bearing strength at the connection point, is prone to sinking, and may even collapse. In addition, the traditional connection method is simple and the splicing is complicated.

[0003] A search revealed that Chinese patent number CN202021810847.3 discloses a novel prefabricated panel that is easy to move and assemble. Although this novel prefabricated panel is easy to transfer, reusable, and saves costs and social resources, and can be disassembled and re-laid when laid incorrectly, reducing the cost of errors, and improves the crack resistance of the novel prefabricated panel by setting a steel plate layer between the first and second impermeable concrete layers, its optimization is directed towards cast-in-place ground and cannot be applied to buildings. At the same time, the movement of this novel prefabricated panel is still not convenient enough, and it cannot be quickly and effectively transported to the transport vehicle, resulting in high transportation costs, which brings about the problem of device defects. Summary of the Invention

[0004] The purpose of this invention is to provide a new type of prefabricated panel that is easy to move and assemble.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel prefabricated panel that is easy to move and assemble, comprising a middle panel and side panels. Grooves are provided on the side walls of both the middle panel and the side panels. A turntable is rotatably fitted into the groove. A slot and an embedding groove are respectively provided on the top surface of the turntable. An embedding post is fitted into the embedding groove. A support frame is fixedly connected to the top surface of the embedding post. A crossbar is fitted onto the other end of the support frame. A roller is rotatably connected to the outer surface of the crossbar.

[0006] Preferably, the inner surface of the groove is provided with an internal thread, the outer surface of the insert post is fixedly connected with an external thread, the bottom wall of the support frame is slidably sleeved with a second locking post, and a spring is installed between the second locking post and the support frame.

[0007] The above solution achieves the following technical effects: it completely fixes the support frame to the turntable, and allows both the middle plate and the side plates to move via the rollers on the support frame, thus achieving the goal of convenient movement of the new type of prefabricated panel.

[0008] Preferably, the external thread and the internal thread are engaged, the second retaining post is engaged with the retaining groove, and the second retaining post and the retaining groove are symmetrically arranged about the central axis of the groove.

[0009] Preferably, the support frame is U-shaped, the turntable has a T-shaped cross-section, the length of the second locking post extending out of the support frame is equal to the pitch of the external thread, and a tie rod is fixedly connected to the top surface of the second locking post.

[0010] Preferably, connecting steel bars are fixedly connected to the side walls of the middle plate and the side plate, and guide grooves are opened on the same side of the middle plate and the side plate, and a guide rod is fixedly connected to the other side of the middle plate.

[0011] The above solution achieves the following technical effects: the guide groove on the side plate can be fitted onto the guide rod, and the connecting steel bar can be inserted into the predetermined position, so that the middle plate and the side plate can be spliced ​​together, achieving the purpose of simple splicing structure.

[0012] Preferably, both the guide groove and the guide rod have a T-shaped cross-section, and the guide rod is fitted into the guide groove.

[0013] Preferably, multiple intermediate plates are provided, and the intermediate plates and side plates are connected by guide grooves and guide rods.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This new type of prefabricated panel is connected by the engagement of the external thread on the insert post with the internal thread in the groove. During this process, the support frame spirals down. When the distance from the bottom surface of the insert post to the bottom surface of the groove is equal to the distance the second clamping post extends out of the support frame, the second clamping post will contact the turntable. As the support frame continues to spiral down, the second clamping post is squeezed and retracted into the support frame by the top surface of the turntable, compressing the spring. When the insert post is fully inserted into the groove, the second clamping post just moves to the groove, releasing the constraint of the second clamping post. Under the spring's rebound, it engages with the groove, achieving the purpose of the second clamping post cooperating with the groove to restrict the rotation of the support frame. This makes the support frame and the turntable completely fixed, allowing the middle panel and the side panels to move via the rollers on the support frame. This achieves the purpose of convenient movement of the new prefabricated panel, which can quickly and effectively transport the new prefabricated panel to the transport vehicle without the need for full-process hoisting, thus reducing transportation costs.

[0016] This new type of prefabricated panel uses a crane to transport the intermediate panel to a designated position, insert the connecting steel bars on the intermediate panel into predetermined positions, and grout them for fixation. Then, the pull rod on the support frame is pulled, causing the pull rod to retract the second locking column into the support frame, and the support frame is rotated in the opposite direction, causing the embedded column on the support frame to separate from the embedded groove, thus completing the dismantling of the support frame. Then, through the above steps, the side panel is transported to one side of the intermediate panel, so that the guide groove on the side panel is aligned with the guide rod on the intermediate panel, and it is slowly lowered, so that the guide groove on the side panel is fitted onto the guide rod, and the connecting steel bars are inserted into predetermined positions, so that the intermediate panel and the side panel are spliced ​​together, achieving the purpose of simple splicing structure and ensuring the splicing effect of the new prefabricated panel.

[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1 and Figure 3-4This invention provides a technical solution: a novel prefabricated panel that is easy to move and assemble, comprising a middle panel 1 and side panels 2. Grooves 6 are provided on the side walls of both the middle panel 1 and the side panels 2. A turntable 7 is rotatably fitted within the groove 6. The top surface of the turntable 7 is provided with a slot 8 and an embedding groove 9. An embedding post 11 is fitted into the embedding groove 9. A support frame 13 is fixedly connected to the top surface of the embedding post 11. A crossbar 14 is fitted onto the other end of the support frame 13. A roller 15 is rotatably connected to the outer surface of the crossbar 14. An internal thread 10 is provided on the inner surface of the embedding groove 9. The outer surface of column 11 is fixed with external thread 12. The bottom wall of support frame 13 is slidably sleeved with a second locking post 19. A spring 20 is installed between the second locking post 19 and support frame 13. The external thread 12 is engaged with the internal thread 10. The second locking post 19 is engaged with the locking groove 8. The second locking post 19 and the locking groove 8 are symmetrically arranged about the central axis of the groove 9. Support frame 13 is U-shaped. The cross-section of turntable 7 is T-shaped. The length of the second locking post 19 extending out of support frame 13 is equal to the pitch of external thread 12. A tie rod is fixed to the top surface of the second locking post 19.

[0025] Specifically, during the movement of the new prefabricated panel, the insert post 11 on the support frame 13 is aligned with the groove 9 on the turntable 7, and the external thread 12 on the insert post 11 engages with the internal thread 10 in the groove 9. During this process, the support frame 13 spirals down. When the distance from the bottom surface of the insert post 11 to the bottom surface of the groove 9 is equal to the distance the second locking post 19 extends out of the support frame 13, the second locking post 19 will contact the turntable 7. As the support frame 13 continues to spiral down, the second locking post 19 is compressed by the top surface of the turntable 7 and retracts into the support frame 13, compressing the spring 20. When the insert post 11 is fully inserted into the groove 9, the second locking post 19 moves to the groove 8, releasing the restraint of the second locking post 19. Under the rebound of the spring 20, it engages with the groove 8, achieving the purpose of the second locking post 19 cooperating with the groove 8 to restrict the rotation of the support frame 13. This makes the support frame 13 completely fixed to the turntable 7, allowing both the middle plate 1 and the side plate 2 to move via the rollers 15 on the support frame 13. This achieves the purpose of convenient movement of the new type of prefabricated plate, which can quickly and effectively transport the new type of prefabricated plate to the transport vehicle without the need for full hoisting, thus reducing transportation costs.

[0026] Example 2:

[0027] Please see Figure 1-2 The present invention provides a technical solution: a novel prefabricated panel that is easy to move and splice, wherein connecting steel bars 3 are fixedly connected to the side walls of the middle panel 1 and the side panel 2, and guide grooves 4 are opened on the same side of the middle panel 1 and the side panel 2, and guide rods 5 are fixedly connected to the other side of the middle panel 1. The cross-sections of the guide grooves 4 and the guide rods 5 are T-shaped, and the guide rods 5 are fitted and connected to the guide grooves 4. Multiple middle panels 1 are provided, and the middle panels 1 and the side panels 2 are connected through the guide grooves 4 and the guide rods 5.

[0028] Specifically, in the process of assembling the new prefabricated panel, the hook of the crane is directly connected to the crossbar 14 on the support frame 13. The intermediate panel 1 is then transported to the designated position by the crane, and the connecting steel bar 3 on the intermediate panel 1 is inserted into the predetermined position and grouted for fixation. Then, the pull rod on the support frame 13 is pulled, causing the pull rod to drive the second locking column 19 to retract into the support frame 13, and the support frame 13 is rotated in the opposite direction, so that the embedded column 11 on the support frame 13 is separated from the embedded groove 9, completing the dismantling of the support frame 13. Then, the side panel 2 is transported to one side of the intermediate panel 1 through the above steps, so that the guide groove 4 on the side panel 2 is aligned with the guide rod 5 on the intermediate panel 1, and it is slowly lowered, so that the guide groove 4 on the side panel 2 is fitted onto the guide rod 5, and the connecting steel bar 3 is inserted into the predetermined position, so that the intermediate panel 1 and the side panel 2 are spliced, achieving the purpose of simple splicing structure and ensuring the splicing effect of the new prefabricated panel.

[0029] Working principle: When transporting new prefabricated panels, the insert post 11 on the support frame 13 is aligned with the groove 9 on the turntable 7, and the external thread 12 on the insert post 11 engages with the internal thread 10 in the groove 9. During this process, the support frame 13 spirals down. When the distance from the bottom surface of the insert post 11 to the bottom surface of the groove 9 is equal to the distance the second locking post 19 extends out of the support frame 13, the second locking post 19 will contact the turntable 7. As the support frame 13 continues to spiral down, the second locking post 19 is compressed by the top surface of the turntable 7 and retracts into the support frame 13, compressing the spring 20. When the insert post 11 is fully inserted into the groove 9, the second locking post 19 moves to the groove 8, releasing the restraint of the second locking post 19 and engaging with the groove 8 under the rebound of the spring 20. This achieves the purpose of the second locking post 19 cooperating with the groove 8 to restrict the rotation of the support frame 13, thereby making the support frame 13 and the turntable 7 completely fixed. This allows both the middle plate 1 and the side plate 2 to move via the rollers 15 on the support frame 13, achieving the purpose of convenient movement of the new type of prefabricated plate. The new type of prefabricated plate can be quickly and effectively transported to the transport vehicle without the need for full hoisting, thus reducing transportation costs.

[0030] When it is necessary to assemble the new type of prefabricated panel, the hook of the crane is directly connected to the crossbar 14 on the support frame 13. Then, the intermediate panel 1 is moved to the designated position by the crane, and the connecting steel bar 3 on the intermediate panel 1 is inserted into the predetermined position and grouted for fixation. Then, the pull rod on the support frame 13 is pulled, so that the pull rod drives the second locking column 19 to retract into the support frame 13, and the support frame 13 is rotated in the opposite direction, so that the embedded column 11 on the support frame 13 is separated from the embedded groove 9, and the support frame 13 is dismantled. Then, the side panel 2 is moved to one side of the intermediate panel 1 through the above steps, so that the guide groove 4 on the side panel 2 is aligned with the guide rod 5 on the intermediate panel 1, and slowly lowered, so that the guide groove 4 on the side panel 2 is fitted onto the guide rod 5, and the connecting steel bar 3 is inserted into the predetermined position, so that the intermediate panel 1 and the side panel 2 are spliced, achieving the purpose of simple splicing structure, which can ensure the splicing effect of the new type of prefabricated panel, and the operation is completed.
