Description

Technical Field

[0001] This application relates to the field of noise-reducing buildings, and in particular to a building structure based on a noise-reducing construction site environment. Background Technology

[0002] Construction workers often live in temporary housing on construction sites for convenience. These temporary houses are generally made of light steel frame with sandwich panels as the enclosure material, which can be easily and quickly assembled and disassembled. However, due to cost considerations, the panels are generally thin and the assembly is relatively loose. When working on the construction site 24 hours a day, this can affect the health and rest of the construction workers. Therefore, some temporary houses incorporate sound-absorbing cotton into the panels to improve the noise reduction and sound insulation effect and improve the living experience of the construction workers.

[0003] Chinese patent CN109629715A, published in the relevant technology, proposes a noise-reducing construction site building structure, including multiple wall panels and a vertical connecting assembly connecting the multiple wall panels in the vertical direction. Each wall panel includes an inner steel plate and a sound-insulating adhesive plate bonded to the outside of the inner steel plate. The middle of the inner steel plate is bent multiple times in the vertical direction to form a vertical connecting square groove in conjunction with the sound-insulating adhesive plate. The vertical connecting assembly includes a base plate, a vertical connecting square tube detachably connected above the base plate and passing through the multiple vertical connecting square grooves, and a vertical clamping plate installed at the upper end of the vertical connecting square tube. After the vertical connecting square tube passes through the multiple vertical connecting square grooves, the base plate and the vertical clamping plate work together to clamp the upper and lower ends of the vertical connecting square tube, fixing the multiple wall panels in the vertical direction. The multiple vertical connecting square tubes, fixed to the base plate, form a complete wall.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Currently, sound-absorbing cotton is mainly connected to steel plates by adhesive. However, in actual use, since the walls of temporary houses are mostly made up of multiple wall panels, moisture will more or less penetrate into the sound-absorbing cotton at the joints of the wall panels, filling the pores in the sound-absorbing cotton and thus greatly reducing the sound absorption and noise reduction effect of the wall panels. Furthermore, replacing the sound-absorbing cotton is quite complicated and easily leads to the waste of sound-absorbing wall panels. Summary of the Invention

[0005] To address the inconvenience of replacing sound-absorbing cotton in soundproof wall panels, this application provides a building structure based on a noise-reducing construction site environment.

[0006] The technical solution provided in this application for a building structure based on a noise-reducing construction site environment is as follows:

[0007] A building structure based on a noise reduction construction site environment includes a wall, the wall being assembled from multiple wall panels, each wall panel including a wall frame and a sound-absorbing cotton layer disposed in the cavity of the wall frame, the wall frame including a top wall frame with an opening at the bottom, multiple middle wall frames with openings at both ends, and a bottom wall frame with an opening at the top, which are assembled sequentially from top to bottom.

[0008] The top of the top wall frame has an installation opening, and the side wall of the bottom wall frame has a replacement opening;

[0009] An installation plate is provided in the cavity of the wall frame along the through direction of the opening of the middle wall frame. The lower end of the installation plate extends to the replacement port. A drive shaft is rotatably provided at both the upper and lower ends of the installation plate. A sprocket is coaxially fixed to the end of the drive shaft. A conveyor chain is pressed against and covered on the two sprockets on the same side. A fixing mechanism is provided on the conveyor chain for fixing the sound-absorbing cotton layer to the conveyor chain.

[0010] By adopting the above technical solution, when assembling temporary housing on the construction site, the bottom wall frame is first installed on the foundation, then multiple middle wall frames are assembled in sequence, and finally the top wall frame is assembled to complete the wall sealing work. After the wall frame is installed, the mounting plate is installed into the cavity of the wall frame through the mounting port. Then, the sound-absorbing cotton layer is installed onto the fixing mechanism through the replacement port. Then, the drive shaft at the lower end of the mounting plate is rotated, and the sound-absorbing cotton layer is driven by the transmission chain to bypass the gap between the mounting plate and the top of the top wall frame and then wrap around the other side of the mounting plate, and finally extend to the replacement port. This can achieve double-layer effective filling of the sound-absorbing cotton layer in the cavity of the wall frame, ensuring the effective sound insulation and noise reduction effect of the sound-absorbing cotton layer as much as possible.

[0011] When it is necessary to replace the damp sound-absorbing cotton layer, the fixing mechanism on the conveyor chain is moved to align with the replacement port, releasing the fixing mechanism from the damp sound-absorbing cotton layer. The damp sound-absorbing cotton layer is then removed from the replacement port, and a new sound-absorbing cotton layer is fixed to the conveyor chain by the fixing mechanism. Then, by rotating the drive shaft, the new sound-absorbing cotton layer can be reinstalled in the cavity of the wall frame. This achieves convenient replacement of the sound-absorbing cotton layer, which is conducive to the repeated turnover and reuse of wall panels and effectively saves energy.

[0012] Optionally, the bottom wall frame is provided with a partition plate at the replacement port. The partition plate extends to one side of the wall frame cavity, close to the outside of the conveyor chain, and the partition plate separates the replacement port into an upper cavity and a lower cavity.

[0013] By adopting the above technical solution, when replacing the sound-absorbing cotton, the moisture-absorbing cotton layer can be removed from the lower cavity, and the new sound-absorbing cotton layer can be inserted from the upper cavity at the same time. One end of the sound-absorbing cotton layer is fixed to the conveyor chain by the fixing mechanism. As the drive shaft rotates, the conveyor chain outputs the moisture-absorbing cotton layer from the lower cavity on the one hand, and at the same time transports the new sound-absorbing cotton layer from the upper cavity to the cavity of the wall frame for wrapping and filling on the other hand, which improves the replacement efficiency of the sound-absorbing cotton layer. In this process, the partition plate can also play a role in separating the new sound-absorbing cotton layer and the moisture-absorbing cotton layer, which can effectively prevent the moisture in the moisture-absorbing cotton from contaminating the new sound-absorbing cotton.

[0014] Optionally, the fixing mechanism includes a fixing pin fixed to the conveyor chain and a fixing plate for abutting the sound-absorbing cotton layer on the conveyor chain. A collar is sleeved on the fixing pin, a limiting ring is fixed to the free end of the fixing pin, a first elastic element is provided between the collar and the limiting ring, and the fixing plate is fixed to the collar.

[0015] By adopting the above technical solution, when fixing the sound-absorbing cotton layer, the fixing mechanism first slides the collar on the fixing pin to move it away from the conveyor chain. At this time, the first elastic element is compressed and deformed. Then, the sound-absorbing cotton layer is inserted between the fixing plate and the conveyor chain. Under the drive of the deformation force of the first elastic element, the fixing plate presses the sound-absorbing cotton layer onto the conveyor chain, thereby achieving a stable fixing effect of the fixing mechanism on the sound-absorbing cotton layer.

[0016] Optionally, the fixing plate includes a pressure plate arranged perpendicular to the axial direction of the fixing pin and a buckle plate arranged along the conveying direction of the conveyor chain, wherein the pressure plate and the buckle plate are integrally formed.

[0017] By adopting the above technical solution, the pressure plate presses the sound-absorbing cotton layer tightly onto the conveyor chain, and the buckles on both sides stably fasten the sound-absorbing cotton layer, which can achieve a more effective fixation effect on the sound-absorbing cotton layer.

[0018] Optionally, a lever is fixedly connected to one side of the collar near the middle of the mounting plate, a flexible connector is connected between the two levers on the two conveyor chains, and a scraper is fixedly connected to the free end of the partition plate. The scraper is located on the travel trajectory of the flexible connector and the sound-absorbing cotton layer.

[0019] By adopting the above technical solution, when it is necessary to replace the sound-absorbing cotton, simply rotate the drive shaft to the conveyor chain to transport the fixing mechanism to the partition plate. As the conveyor chain continues to transport, the scraper first abuts against the flexible connector, and then pulls the two levers at both ends of the flexible connector to flip in a direction away from each other. This causes the two collars and the fixing plates on them to flip in a direction away from each other on the fixing pins. At this time, the fixing mechanism automatically releases its fixing effect on the sound-absorbing cotton layer. As the conveyor chain continues to transport, the sound-absorbing cotton layer on it is peeled off from the conveyor chain under the action of the scraper and output from the lower cavity. Thus, the automatic peeling effect of the damp sound-absorbing cotton layer is achieved by the scraper on the partition plate, which does not require much operation by the operator and further improves the convenience of replacing the sound-absorbing cotton.

[0020] Optionally, the scraper has an arc surface on one side near the bottom wall of the bottom wall frame, and the scraper has a plurality of grooves on the arc surface that fit with the flexible connector, the groove depth being less than the outer diameter of the cross section of the flexible connector.

[0021] By adopting the above technical solution, after the fixing mechanism releases the fixing effect on the sound-absorbing cotton layer, the conveyor chain continues to transmit. The flexible connector is hooked into the groove on the inclined surface of the scraper, which can ensure that the flexible connector can stably pull the lever to release the fixing plate from the fixing effect on the sound-absorbing cotton layer. At the same time, the arc surface set on the scraper can allow the flexible connector to pass over the scraper under the guidance of the arc surface after the fixing plate passes over the partition plate, so that the fixing mechanism can fix the new sound-absorbing cotton layer.

[0022] Optionally, the partition plate is hinged to the bottom wall frame on the side near the replacement port, and the bottom wall frame is provided with a locking mechanism for locking the partition plate to maintain the state in which the free end of the partition plate is close to the outside of the conveyor chain.

[0023] By adopting the above technical solution, after the damp sound-absorbing cotton layer is replaced, the locking structure can be released from the partition plate, and the partition plate can be flipped to fit against the side wall of the bottom wall frame, which makes it easy for the sound-absorbing cotton layer to completely fill the cavity of the wall frame; when the sound-absorbing cotton needs to be replaced, the partition plate can be flipped and locked by the locking mechanism.

[0024] Optionally, the locking mechanism includes a locking gear ring and a locking gear meshing with it. The locking gear ring is fixedly connected to the side wall of the bottom wall frame, and a hinge shaft is fixedly connected to the partition plate, and the partition plate is hinged to the bottom wall frame through the hinge shaft.

[0025] The locking gear is slidably disposed on the hinge shaft along its axial direction, and the locking gear rotates in tandem with the hinge shaft.

[0026] By adopting the above technical solution, when it is necessary to flip the partition plate, the locking gear is slid on the hinge shaft to disengage it from the locking gear ring, at which point the partition plate can be rotated freely; when the partition plate is flipped from the designated position, the locking gear is slid again to engage with the locking gear ring, which can lock the partition plate, and the partition plate is generally kept in this state.

[0027] Optionally, a second elastic element is provided between the locking gear and the partition plate;

[0028] When the locking gear disengages from the locking gear ring, the second elastic element is in a compressed state.

[0029] By adopting the above technical solution, the second elastic element can ensure that the locking gear always meshes with the locking gear ring without external force, thereby ensuring a stable locking effect on the partition plate.

[0030] Optionally, the two inner sidewalls of the wall frame that are arranged opposite each other in the thickness direction are provided with sliding grooves that are adapted to slide with the sidewall of the mounting plate, and the lower end of the sliding groove does not completely penetrate the bottom wall frame;

[0031] Furthermore, when the mounting plate abuts against the lower end wall of the slide groove, gaps are reserved between the upper end of the mounting plate and the top wall of the top wall frame, and between the lower end of the mounting plate and the bottom wall of the bottom wall frame.

[0032] By adopting the above technical solution, the slide can stabilize and limit the mounting plate, so that the sound-absorbing cotton layer can be stably wrapped around the periphery of the mounting plate when the sound-absorbing cotton is replaced.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. When it is necessary to replace the damp sound-absorbing cotton layer, move the fixing mechanism on the conveyor chain to align with the replacement port, release the fixing mechanism from the damp sound-absorbing cotton layer, remove the damp sound-absorbing cotton layer from the replacement port, and at the same time fix the new sound-absorbing cotton layer on the conveyor chain through the fixing mechanism. Then rotate the drive shaft to reinstall the new sound-absorbing cotton layer in the cavity of the wall frame. This realizes the convenient replacement of the sound-absorbing cotton layer, which is conducive to the repeated turnover and reuse of the wall panel.

[0035] 2. After the partition plate is installed, when replacing the sound-absorbing cotton, the conveyor chain will output the damp sound-absorbing cotton layer from the lower cavity during the transmission process, and at the same time, it can transport the new sound-absorbing cotton layer from the upper cavity to the cavity of the wall frame for wrapping and filling, which improves the replacement efficiency of the sound-absorbing cotton layer; during this process, the partition plate can also separate the new sound-absorbing cotton layer from the damp sound-absorbing cotton layer, which can effectively prevent the moisture in the damp sound-absorbing cotton from contaminating the new sound-absorbing cotton.

[0036] 3. After the scraper is installed, when the sound-absorbing cotton needs to be replaced, the drive shaft is continuously rotated. The scraper first abuts against the flexible connector, and then pulls the two levers at both ends of the flexible connector to flip in a direction away from each other. At this time, the fixing mechanism automatically releases the fixing effect on the sound-absorbing cotton layer. As the conveyor chain continues to transmit, the sound-absorbing cotton layer on it is peeled off from the conveyor chain under the action of the scraper and output from the lower cavity. Thus, the automatic peeling effect of the damp sound-absorbing cotton layer is achieved by the scraper on the partition plate, which does not require much operation by the operator and further improves the convenience of replacing the sound-absorbing cotton.

[0051] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0052] This application discloses a building structure based on a noise-reducing construction site environment. (Refer to...) Figure 1 and Figure 2 The building structure based on noise reduction construction site environment includes walls, which are horizontally spliced ​​from multiple wall panels 1. During splicing, the multiple wall panels 1 are positioned by upper and lower beams with a "U" shaped cross-section. The upper and lower ends of the wall panels 1 are respectively inserted and fitted into the upper and lower beams. The wall panel 1 includes a wall frame and a sound-absorbing cotton layer 11 disposed in the cavity of the wall frame. The wall frame includes a top wall frame 2 with an opening at the bottom, multiple middle wall frames 3 with openings at both ends, and a bottom wall frame 4 with an opening at the top, which are spliced ​​from top to bottom. The wall panel 1 also includes two U-shaped vertical beams with opening directions opposite each other. The bottom wall frame 4, multiple middle wall frames 3 and the top wall frame 2 are sequentially embedded between the two vertical beams.

[0053] Specifically, refer to Figure 2 and Figure 3 The top of the top wall frame 2 has an installation opening 21, and the side wall of the bottom wall frame 4 has a replacement opening 41. A sealing plate 13 is hinged to the top wall frame 2 at the installation opening 21, and a sealing plate 13 is also hinged to the bottom wall frame 4 at the replacement opening 41. An installation plate 5 is provided in the cavity of the wall frame along the through direction of the opening of the middle wall frame 3. It should be noted that the two inner side walls of the wall frame that are arranged opposite each other in the thickness direction are provided with sliding grooves 12 that are adapted to slide with the side walls of the installation plate 5. The lower end of the sliding groove 12 does not completely penetrate the bottom wall frame 4. When the installation plate 5 is pressed against the lower end wall of the sliding groove 12, a gap is reserved between the upper end of the installation plate 5 and the top wall of the top wall frame 2, and between the lower end of the installation plate 5 and the bottom wall of the bottom wall frame 4. Meanwhile, both the upper and lower ends of the mounting plate 5 are rotatably equipped with drive shafts 51, and sprockets 52 are coaxially fixed to the ends of the drive shafts 51. The two sprockets 52 on the same side are together pressed against and covered by a conveyor chain 53. A fixing mechanism for fixing the sound-absorbing cotton layer 11 to the conveyor chain 53 is provided on the conveyor chain 53.

[0054] Therefore, when assembling temporary houses on the construction site, the lower beam is first installed on the foundation, and then multiple wall panels 1 are assembled in sequence inside the lower beam. The specific assembly method of the wall panel 1 is to first insert two vertical beams on the lower beam and fix them, then install the bottom wall frame 4 between the two vertical beams, and then assemble multiple middle wall frames 3 in sequence. Finally, the top wall frame 2 is assembled to complete the wall capping operation and form the wall frame.

[0055] After the wall frame is installed, the mounting plate 5 is inserted into the sliding groove 12 of the wall frame through the mounting port 21, so that the lower end of the mounting plate 5 is aligned with the replacement port 41. Then, the sound-absorbing cotton layer 11 is installed onto the fixing mechanism through the replacement port 41. Then, the drive shaft 51 at the lower end of the mounting plate 5 is rotated, and the sound-absorbing cotton layer 11 is driven by the transmission chain 53 to bypass the gap between the mounting plate 5 and the top of the top wall frame 2 and then wrap around the other side of the mounting plate 5, and finally extend to the replacement port 41. This can achieve double-layer effective filling of the sound-absorbing cotton layer 11 in the cavity of the wall frame, and ensure the effective sound insulation and noise reduction effect of the sound-absorbing cotton layer 11 as much as possible.

[0056] When it is necessary to replace the damp sound-absorbing cotton layer 11, the fixing mechanism on the conveyor chain 53 is moved to align with the replacement port 41, the fixing mechanism is released from the fixing effect of the damp sound-absorbing cotton layer 11, the damp sound-absorbing cotton layer 11 is taken out from the replacement port 41, and at the same time, the new sound-absorbing cotton layer 11 is fixed on the conveyor chain 53 by the fixing mechanism. Then, the drive shaft 51 is rotated, and the new sound-absorbing cotton layer 11 can be reinstalled in the cavity of the wall frame. This realizes the convenient replacement of the sound-absorbing cotton layer 11, which is conducive to the repeated turnover and reuse of the wall panel 1 and effectively saves energy.

[0057] To simplify the replacement process of sound-absorbing cotton, refer to Figure 2 and Figure 3 A partition plate 6 is provided at the replacement port 41 of the bottom wall frame 4. The partition plate 6 extends to one side of the wall frame cavity, close to the outside of the conveyor chain 53. The partition plate 6 divides the replacement port 41 into an upper cavity 411 and a lower cavity 412.

[0058] In this way, when replacing the sound-absorbing cotton, the moisture-absorbing cotton layer 11 can be taken out from the lower cavity 412, and the new sound-absorbing cotton layer 11 can be inserted from the upper cavity 411 at the same time. One end of the sound-absorbing cotton layer 11 is fixed to the conveyor chain 53 by the fixing mechanism. As the drive shaft 51 rotates, the conveyor chain 53 outputs the moisture-absorbing cotton layer 11 from the lower cavity 412 on the one hand, and at the same time transports the new sound-absorbing cotton layer 11 from the upper cavity 411 to the cavity of the wall frame for wrapping and filling on the other hand, which improves the replacement efficiency of the sound-absorbing cotton layer 11. During this process, the partition plate 6 can also play a role in separating the new sound-absorbing cotton layer 11 and the moisture-absorbing cotton layer 11, which can effectively prevent the moisture in the moisture-absorbing cotton from contaminating the new sound-absorbing cotton.

[0059] Considering that the sound-absorbing cotton layer 11 can be made into a long plate shape, in order to facilitate the fixation of the sound-absorbing cotton layer 11 onto the conveyor chain 53 by the fixing mechanism, refer to Figure 3 and Figure 4The fixing mechanism includes a fixing pin 71 fixed to the conveyor chain 53 and a fixing plate 72 for securing the sound-absorbing cotton layer 11 to the conveyor chain 53. A collar 73 is sleeved on the fixing pin 71, and a limiting ring 74 is fixed to the free end of the fixing pin 71. A first elastic element 75 is provided between the collar 73 and the limiting ring 74. In this embodiment, the first elastic element is a spring sleeved on the fixing pin 71. The fixing plate 72 is fixed to the periphery of the collar 73. More specifically, the fixing plate 72 includes a pressure plate 721 arranged perpendicular to the axial direction of the fixing pin 71 and a buckle plate 722 arranged along the conveying direction of the conveyor chain 53. The pressure plate 721 and the buckle plate 722 are integrally formed.

[0060] Thus, when fixing the sound-absorbing cotton layer 11, the fixing mechanism first slides the collar 73 on the fixing pin 71 away from the conveyor chain 53. At this time, the first elastic element 75 is compressed and deformed. Then, the sound-absorbing cotton layer 11 is inserted between the fixing plate 72 and the conveyor chain 53. Driven by the deformation force of the first elastic element 75, the fixing plate 72 presses the sound-absorbing cotton layer 11 tightly onto the conveyor chain 53, thereby achieving a stable fixing effect of the fixing mechanism on the sound-absorbing cotton layer 11.

[0061] In another feasible embodiment, Velcro hooks can be further installed on the outer side wall of the conveyor chain 53, so that the side of the sound-absorbing cotton layer 11 in the length direction can be attached to the conveyor chain 53 through the Velcro hooks, which further effectively ensures the synchronicity of the sound-absorbing cotton layer 11 as it moves with the conveyor chain 53 in the cavity of the wall frame.

[0062] However, when actually replacing the damp sound-absorbing cotton layer 11, due to its long service life and the large amount of moisture it has absorbed, manually peeling off the sound-absorbing cotton layer 11 is inconvenient. Therefore, referring to... Figure 3 and Figure 4 A lever 76 is fixedly connected to the side of the collar 73 near the middle of the mounting plate 5. A flexible connector 77 is connected between the two levers 76 on the two conveyor chains 53. The flexible connector 77 is set as a conventional rope or an elastic rope with a certain elasticity. In this embodiment, a conventional rope is selected. At the same time, a scraper 61 is fixedly connected to the free end of the partition plate 6. The scraper 61 is located on the travel trajectory of the flexible connector 77 and the sound-absorbing cotton layer 11. The length of the scraper 61 is less than the length of the partition plate 6 so that both ends of the partition plate 6 are reserved with space for the fixed plate 72 on one side to pass through without obstruction.

[0063] When the drive shaft 51 is rotated to the conveyor chain 53 to transport the fixing mechanism to the partition plate 6, as the conveyor chain 53 continues to transport, the scraper 61 first abuts against the flexible connector 77, and then pulls the two levers 76 at both ends of the flexible connector 77 to flip in a direction away from each other, thereby driving the two collars 73 and the fixing plates 72 on them to flip in a direction away from each other on the fixing pins 71. At this time, the fixing mechanism automatically releases the fixing effect on the sound-absorbing cotton layer 11. As the conveyor chain 53 continues to transport, the sound-absorbing cotton layer 11 on it is peeled off from the conveyor chain 53 under the action of the scraper 61 and output from the lower cavity 412. Thus, the scraper 61 on the partition plate 6 achieves the automatic peeling effect of the damp sound-absorbing cotton layer 11, without the need for excessive operation by the operator, further improving the convenience of replacing the sound-absorbing cotton.

[0064] Furthermore, refer to Figure 3 and Figure 4 The scraper 61 has an arc surface 611 on one side near the bottom wall of the bottom wall frame 4. Multiple grooves 612 are formed on the arc surface 611 of the scraper 61, which fit into the flexible connector 77. The depth of the grooves 612 is less than the outer diameter of the flexible connector 77. After the fixing mechanism releases the sound-absorbing cotton layer 11, the conveyor chain 53 continues to transmit. The flexible connector 77 hooks into the grooves 612 on the inclined surface of the scraper 61, ensuring that the flexible connector 77 can stably pull the lever 76 to release the fixing plate 72 from the sound-absorbing cotton layer 11. Simultaneously, the arc surface 611 on the scraper 61 allows the flexible connector 77 to also pass over the scraper 61 under the guidance of the arc surface 611 after the fixing plate 72 has passed the partition plate 6, so that the fixing mechanism can fix the new sound-absorbing cotton layer 11.

[0065] To facilitate the storage of the partition panel 6 and ensure that the sound-absorbing cotton layer 11 can fill the cavity of the wall frame as completely as possible, thus guaranteeing the sound insulation effect of the wall panel 1, refer to... Figure 2 and Figure 5 The partition plate 6 is hinged to the bottom wall frame 4 on the side near the replacement port 41. The bottom wall frame 4 is provided with a locking mechanism for locking the partition plate 6 and keeping the free end of the partition plate 6 close to the outside of the conveyor chain 53. The locking mechanism includes a locking gear ring 81 and a locking gear 82 that meshes with it. The locking gear ring 81 is fixed to the side wall of the bottom wall frame 4. A hinge shaft 83 is fixed to the partition plate 6 and the partition plate 6 is hinged to the bottom wall frame 4 through the hinge shaft 83.

[0066] Reference Figure 5A locking gear 82 is slidably mounted on the hinge shaft 83 along its axial direction. The locking gear 82 rotates in tandem with the hinge shaft 83. Specifically, a key block along its axial direction is fixed to the circumference of one end of the hinge shaft 83 near the locking gear ring 81. A keyway adapted to slide on the gear is provided. A second elastic element 84 is provided between the locking gear 82 and the partition plate 6. When the locking gear 82 disengages from the locking gear ring 81, the second elastic element 84 is in a compressed state.

[0067] When the partition plate 6 needs to be flipped, the locking gear 82 slides on the hinge shaft 83 to disengage it from the locking gear ring 81, allowing the partition plate 6 to rotate freely. When the partition plate 6 is flipped from the designated position, the locking gear 82 is slid back to engage with the locking gear ring 81, locking the partition plate 6. The partition plate 6 is generally held in this state. Furthermore, the second elastic element 84 ensures that the locking gear 82 remains engaged with the locking gear ring 81 without external force, thus guaranteeing a stable locking effect on the partition plate 6.

[0068] Furthermore, considering the limited space in wall panel 1, making it inconvenient to rotate the drive shaft 51, refer to... Figure 2 and Figure 5 A rotating shaft 91 is rotatably mounted on the lower side wall of the bottom wall frame 4. The rotating shaft 91 is positioned along the thickness direction of the bottom wall frame 4. A worm gear 92 is coaxially fixed to one end of the rotating shaft 91 located in the cavity of the wall frame. A worm wheel 93, which meshes with the worm gear 92, is rotatably connected to the bottom wall frame 4. When the mounting plate 5 is installed in place within the wall frame, the drive shaft 51 and the worm wheel 93 are coaxial. Furthermore, a drive pin is elastically slidably inserted at the end of the drive shaft 51 along its axial direction. The cross-section of the drive pin is non-circular; in this embodiment, the cross-section of the drive pin is square. A drive groove adapted to the insertion of the drive pin is opened at the center of the worm wheel 93 near the drive shaft 51. Moreover, a guide slope is provided on the side of the drive pin near the bottom wall of the bottom wall frame 4.

[0069] Thus, during the installation of mounting plate 5, as mounting plate 5 is inserted from sliding groove 12 until mounting plate 5 is installed in place, the axial side wall line of worm gear 93 pushes the transmission pin into the transmission shaft 51 through the guide slope on the transmission pin. When mounting plate 5 is installed in place, one end of transmission pin springs into the transmission groove of worm gear 93. At this time, worm gear 93 and transmission shaft 51 achieve synchronous transmission, so that rotating worm 92 can realize the rotation of transmission shaft 51.

[0070] Furthermore, refer to Figure 5 A circular groove 94 coaxial with the rotating shaft 91 is provided on the side wall of the bottom wall frame 4 in the thickness direction. One end of the rotating shaft 91 extends into the circular groove 94, and a handle 95 is hinged to the end of the rotating shaft 91. When the handle 95 is flipped, it can be accommodated in the circular groove 94. This can achieve a convenient driving effect for the transmission shaft 51 without having a significant impact on the external structure of the wall panel 1.

[0071] The implementation principle of a building structure based on a noise reduction construction site environment in this application embodiment is as follows: When the sound-absorbing cotton needs to be replaced, the transmission shaft 51 is continuously rotated. The scraper 61 first abuts against the flexible connector 77, and then pulls the two levers 76 at both ends of the flexible connector 77 to flip in a direction away from each other. At this time, the fixing mechanism automatically releases the fixing effect on the sound-absorbing cotton layer 11. As the conveyor chain 53 continues to transmit, the sound-absorbing cotton layer 11 on it is peeled off from the conveyor chain 53 under the action of the scraper 61 and output from the lower cavity 412. Thus, the automatic peeling effect of the damp sound-absorbing cotton layer 11 is achieved by the scraper 61 on the partition plate 6, without the need for excessive operation by the operator, further improving the convenience of replacing the sound-absorbing cotton.

[0072] 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.
