Description
Technical Field
[0001] This utility model relates to the technical field of sandwich steel plate splicing mechanisms, specifically to a rapid splicing mechanism for prefabricated sandwich steel plate partition walls. Background Technology
[0002] Prefabricated sandwich panels consist of two layers of thin steel plates (panels) and a lightweight core material (such as rock wool, polyurethane, paper honeycomb, etc.) filled in between. The core of the rapid splicing of two steel plates is the use of male and female tenon joints. Usually, on the left and right edges of the wall panel, one side is designed as the male tenon and the other side as the female tenon. The male tenon of one wall panel is aligned with the female tenon of the other wall panel. Using the guide bevel of the male tenon, it is inserted into the groove of the female tenon. Through a simple mechanical action (such as knocking, rotating, or pushing in a wedge-shaped locking key), the snap-fit or elastic structure inside the male and female tenons engages, achieving longitudinal (perpendicular to the ground) and lateral (perpendicular to the panel surface) constraints. The upper and lower ends of a wall panel are usually fixed to the building structure (floor slab, ground) by connectors, while the connection between the panels relies entirely on this side splicing mechanism.
[0003] Traditional methods achieve quick alignment and initial connection of wall panels using simple male and female tenon joints and built-in rubber strips. However, this method cannot fully solve the problems caused by excessive tolerances in the male and female tenon joints, which result in wide, unsightly, and reduced sound insulation performance. Conversely, excessive tolerances can lead to installation difficulties or even failure to insert the panels, resulting in damage to the panels and sealing strips due to forceful impacts.
[0004] Therefore, it is necessary to invent a prefabricated sandwich panel partition wall quick splicing mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a quick-assembly mechanism for prefabricated sandwich steel panel partition walls. By using a rubber block inside the female tenon, even with minor tolerances during assembly with the male tenon, the deformation of the elastic body can compress the male tenon, achieving an "interference fit, self-guiding, and tolerance compensation" effect, and compensating for thermal expansion and contraction. Based on a simple insertion structure, an independent locking structure is added. After installation, a dedicated hexagonal screwdriver is used to tighten the hexagonal screw, which, in conjunction with the insertion of the moving sleeve, drives four wedge-shaped blocks outward, causing the connecting blocks to engage with the slots for rigid locking. This secondary locking action ensures that the connection structure will not loosen under vibration and long-term use, greatly improving the strength and reliability of the connection. This addresses the problems in existing technologies where excessive tolerances in the male and female tenon fit lead to wide, unsightly, and reduced sound insulation performance, while insufficient tolerances result in difficult installation or even inability to insert, leading to damage to the panels and sealing strips from forceful impacts.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated sandwich steel panel partition wall quick-assembly mechanism, comprising a sandwich steel panel body, on both sides of which a male and female tenon are detachably installed, respectively; symmetrical sealing strips are fixed to the outer side of the female tenon; rubber blocks are fixed to the top and bottom walls inside the female tenon; locking structures are movably inserted through the top and bottom of the female tenon; multiple locking structures are provided, with two connected locking structures symmetrically distributed about the top or bottom of the female tenon; each locking structure includes a shell, on which a hexagonal screw is threaded. The hexagonal screw is threaded with a movable sleeve located inside the outer shell. Guide blocks are fixedly connected to both sides of the movable sleeve. Guide grooves matching the guide blocks are opened on both sides of the inner wall of the outer shell. Wedge-shaped blocks located below the movable sleeve are slidably installed on both sides and the front and rear sides of the inner wall of the outer shell. Springs are fixedly connected between the wedge-shaped blocks and the inner wall of the outer shell. A locking block is fixedly connected to the outer side of the wedge-shaped blocks. Positioning grooves matching the outer shell are symmetrically opened on the top and bottom of the male falcon. A locking groove communicating with the positioning groove is opened on the inner wall of the male falcon. The locking groove cooperates with the locking block.
[0007] Preferably, both the male and female falcons have symmetrically fixed protrusions on the side that is in close contact with the sandwich steel plate, and both sides of the sandwich steel plate are symmetrically provided with grooves that match the protrusions.
[0008] Preferably, fastening screws are symmetrically inserted between the top and bottom of the protrusion and the groove, and the fastening screws are threadedly connected to the sandwich steel plate body.
[0009] Preferably, the top and bottom of the female falcon are provided with sound-absorbing channels that penetrate the sealing strip.
[0010] Preferably, the sealing strip has equally spaced glue injection holes, which are connected to the noise reduction channel.
[0011] Preferably, a pipeline channel is provided at the bottom of the sandwich steel plate.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By using the rubber block inside the female falcon, even with minor tolerances during assembly and splicing with the male falcon, the deformation of the elastomer can compress the male falcon, achieving the effects of "interference fit, self-guiding, and tolerance compensation," and compensating for thermal expansion and contraction. In addition to the simple insertion structure, an independent locking structure is added. After installation, a special hex screwdriver is used to turn the hex screw, which, together with the insertion of the moving sleeve, drives the four wedge blocks outward, so that the connecting blocks engage with the slots to achieve rigid locking. The secondary locking action ensures that the connection structure will not loosen under vibration and long-term use, which greatly improves the strength and reliability of the connection. By designing a sound-absorbing channel extending into the female falcon at the joint where the male and female falcons are spliced, the duration of noise staying in the sound-absorbing channel is effectively increased. Furthermore, an injection hole is reserved between the splicing mechanism and the sound-absorbing channel. If extremely high sound insulation is required, or if a certain area of insufficient sealing is detected, foamed sealant can be injected into the joint through this hole to form a seamless and permanent sealing layer, which greatly improves the sealing performance.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figure 1-6The prefabricated sandwich steel panel partition wall quick splicing mechanism shown includes a sandwich steel panel body 1. Male tenon 2 and female tenon 3 are detachably installed on both sides of the sandwich steel panel body 1. A sealing strip 4 is symmetrically fixed on the outer side of the female tenon 3. The sealing strip 4 cooperates with the sound-absorbing channel 19 and the glue injection hole 20 to improve the sealing effect between the male tenon 2 and the female tenon 3. Rubber blocks 5 are fixed to the top and bottom walls of the female falcon 3. The elastic deformation of the rubber blocks 5 presses the male falcon 2 in the female falcon 3 to achieve the effect of "interference fit" and at the same time compensate for thermal expansion and contraction. Locking structures 6 are movable through the top and bottom of the mother falcon 3. Multiple locking structures 6 are provided, with two connected locking structures 6 symmetrically distributed about the top or bottom of the mother falcon 3. Each locking structure 6 includes a housing 601, with a hexagonal screw 7 threaded through it. A movable sleeve 8 located inside the housing 601 is threaded onto the hexagonal screw 7. Guide blocks 9 are fixedly connected to both sides of the movable sleeve 8. Guide grooves 10 matching the guide blocks 9 are provided on both sides of the inner wall of the housing 601. Wedge-shaped blocks 11 located below the movable sleeve 8 are slidably installed on both sides and the front and rear sides of the inner wall of the housing 601. Springs 12 are fixedly connected between the wedge-shaped blocks 11 and the inner wall of the housing 601. A locking block is fixedly connected to the outer side of the wedge-shaped blocks 11. 13. The top and bottom of the male tenon 2 are symmetrically provided with positioning grooves 14 that match the outer shell 601. The inner wall of the male tenon 2 is provided with a slot 15 that communicates with the positioning groove 14. The slot 15 cooperates with the locking block 13. When the hexagonal screw 7 is rotated and the guide block 9 is guided to slide along the guide groove 10, the auxiliary moving sleeve 8 can be limited to move linearly along the hexagonal screw 7. When it moves into the outer shell 601, the spherical structure at the bottom of the moving sleeve 8 will squeeze the four wedge blocks 11. The four wedge blocks 11 are subjected to force and slide outwards together, which will drive the locking block 13 to engage with the slot 15 in the positioning groove 14 to achieve rigid locking. The secondary locking action is used to ensure that the connection structure will not loosen under vibration and long-term use, which greatly improves the strength and reliability of the connection.
[0018] Both male tenon 2 and female tenon 3 have symmetrically fixed protrusions 16 on the side that is in close contact with the sandwich steel plate 1. Both sides of the sandwich steel plate 1 have symmetrically opened grooves 17 that match the protrusions 16. Designing male tenon 2 and female tenon 3 as independent, detachable aluminum alloy bodies, and fixing the protrusions 16 and grooves 17 with fastening screws 18, connects them to the sandwich steel plate 1. If damaged, only this profile needs to be replaced, without scrapping the entire wall panel.
[0019] Fastening screws 18 are symmetrically inserted between the top and bottom of the protrusion 16 and the groove 17, and the fastening screws 18 are threadedly connected to the sandwich steel plate 1.
[0020] The top and bottom of the mother falcon 3 are provided with noise reduction channels 19 that pass through the sealing strip 4. The noise reduction channels 19 can effectively increase the time that noise stays inside and gradually dissipate, thereby achieving noise elimination.
[0021] The sealing strip 4 has equally spaced injection holes 20, which are connected to the sound-absorbing channel 19. The injection holes 20 are reserved between the splicing mechanism and the sound-absorbing channel 19 so that if there are extremely high requirements for sound insulation, or if a certain area is found to be insufficiently sealed, foamed sealant can be injected into the joint through this hole to form a seamless and permanent sealing layer, which greatly improves the sealing performance.
[0022] The bottom of the sandwich steel plate body 1 is provided with a pipeline channel 21. The pipeline channel 21 has space inside to arrange electrical wires and low-voltage lines, which realizes the integration of structure and function.
[0023] The working principle of this practical application is as follows: Before use, the male tenon 2 and female tenon 3 can be fixedly connected to the sandwich steel plate 1 by tightening screws 18. Then, two adjacent sandwich steel plates 1 are joined by the male tenon 2 and female tenon 3. A special hex screwdriver is used to turn the hex screw 7, which, together with the inward movement of the moving sleeve 8, drives the four wedge blocks 11 outward, so that the connecting block 13 and the slot 15 are locked together to achieve rigid locking. By designing a sound-absorbing channel 19 extending into the female tenon 3 at the joint of the male tenon 2 and female tenon 3, the duration of noise staying in the sound-absorbing channel 19 is effectively increased. In addition, an injection hole 20 is reserved between the splicing mechanism and the sound-absorbing channel 19, so that if there are extremely high requirements for sound insulation, or if a certain sealing is insufficient, foamed sealant can be injected into the joint through this hole to form a seamless and permanent sealing layer.
[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
