Description

Technical Field

[0001] This utility model relates to the field of building wall technology, and in particular to a thermal insulation and soundproof building wall. Background Technology

[0002] Prefabricated buildings refer to buildings assembled on-site from prefabricated components. They can be mainly divided into five types: block buildings, panel buildings, box-type buildings, frame panel buildings, and lift-slab / lift-floor buildings. Currently, to achieve green and energy-saving effects, lightweight building walls are prefabricated and then transported to designated locations for assembly. To ensure the thermal insulation and sound insulation performance of prefabricated building walls, insulation boards and sound insulation boards are correspondingly installed at the main structure of the building walls. During the assembly process, the thermal insulation and sound insulation effect at the edges of the building walls is relatively weak, or even nonexistent. This results in a large gap between the thermal insulation and sound insulation effect at the connection points of two adjacent walls and the thermal insulation and sound insulation effect at the main body of the building walls. Consequently, the overall thermal insulation and sound insulation performance of prefabricated building walls is uneven and difficult to avoid.

[0003] Chinese utility model patent CN218116849U discloses a building wall component with edge thermal insulation and sound insulation, relating to the technical field of building wall components. It includes a main building wall body, with L-shaped grooves on both sides along its length. A storage groove is formed on the inner wall of each L-shaped groove, and a movable thermal insulation and sound insulation panel is slidably installed on the inner wall of the storage groove. Both sides of the main building wall body along its length also have recessed grooves for use with the movable thermal insulation and sound insulation panels. This utility model utilizes the interplay between the main building wall body, L-shaped grooves, storage grooves, movable thermal insulation and sound insulation panels, recessed grooves, and fixed thermal insulation and sound insulation panels. Movable thermal insulation and sound insulation panels are installed at both ends of the main building wall body. By using two movable thermal insulation and sound insulation panels at the connection point of two main building wall bodies, thermal insulation and sound insulation are achieved, effectively improving the thermal insulation and sound insulation effect at the connection point of two main building wall bodies, thereby enhancing the overall thermal insulation and sound insulation performance of the prefabricated building wall.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In order to improve the thermal insulation and sound insulation effect at the connection point of two walls, the above-mentioned device pre-fixes the main body of two adjacent building walls by connecting the pre-positioning rod and the positioning groove, and drives the thermal insulation and sound insulation board to connect with the groove by pushing the push-pull seat. In actual use, due to tolerance issues, the connection between the thermal insulation and sound insulation board and the groove is prone to high tightness. At this time, simply pushing the push-pull seat is difficult to drive the thermal insulation and sound insulation board to connect with the groove, which easily leads to the thermal insulation and sound insulation board not being able to cover the groove, resulting in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a thermal insulation and soundproof building wall.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a thermal insulation and soundproof building wall, comprising a building wall body, a first mounting plate and a second mounting plate fixed on one side wall of the building wall body, a stabilizing plate fixed on the other side wall of the building wall body, a first T-shaped groove formed on the upper surface of the stabilizing plate, a second T-shaped groove formed on the upper surface of the building wall body, a first T-shaped rod slidably disposed in the first T-shaped groove, a fixing bolt installed on the side wall of the first mounting plate, a sliding groove formed on the side wall of the building wall body, a first thermal insulation and soundproof board slidably disposed in the sliding groove, a connecting groove matching the first thermal insulation and soundproof board formed on the side wall of the stabilizing plate, and a driving component for driving the first thermal insulation and soundproof board provided on the stabilizing plate.

[0007] By adopting the above technical solution, when workers need to connect two building wall structures, they need to align the width of the two adjacent building wall structures and move them closer to each other. This allows the stabilizing plate on one building wall structure to move between the first and second mounting plates on the other building wall structure, thus blocking the stabilizing plate. At this point, workers only need to connect the two ends of the first T-shaped rod to the first and second T-shaped grooves respectively to initially stabilize the two building wall structures.

[0008] Subsequently, the workers need to activate the drive assembly, which allows the first thermal insulation and soundproofing panel to connect with the connecting groove. This allows the first thermal insulation and soundproofing panel to shield the connection between the two building wall structures, thereby improving the thermal insulation effect at the connection and reducing the difficulty of installing the first thermal insulation and soundproofing panel. Next, the workers need to connect the fixing bolts with the first mounting plate, allowing the fixing bolts to penetrate the first mounting plate, the second mounting plate, the stabilizing plate, and the first thermal insulation and soundproofing panel, thus stabilizing the two building wall structures.

[0009] Furthermore, the driving assembly includes a second thermal insulation and sound insulation board slidably disposed in the connecting groove, a second T-shaped rod slidably connected to the upper surface of the second thermal insulation and sound insulation board, and a moving device disposed on the main body of the building wall for driving the second thermal insulation and sound insulation board. The upper surface of the first thermal insulation and sound insulation board is provided with a third T-shaped groove that matches the second T-shaped rod.

[0010] By adopting the above technical solution, when workers need to connect the first thermal insulation and soundproofing board to the connecting groove, they need to move the two main building wall structures closer together, so that the first and second thermal insulation and soundproofing boards can abut against each other. Then, workers need to connect the two ends of the second T-shaped rod to the third T-shaped groove and the second thermal insulation and soundproofing board respectively, so that the first and second thermal insulation and soundproofing boards are connected and stabilized. Subsequently, workers need to continue moving the two main building wall structures closer together, so that the stabilizing plate is pressed against one of the main building wall structures, thereby aligning the first T-shaped groove on one main building wall structure with the second T-shaped groove on the other. At this point, workers only need to connect the two ends of the first T-shaped rod to the first and second T-shaped grooves respectively to initially stabilize the two main building wall structures.

[0011] Furthermore, workers only need to activate the moving device to move the second thermal insulation and soundproofing panel closer to the connecting groove. This causes the first thermal insulation and soundproofing panel to move along with the second panel, ultimately bringing the second panel against the inner wall of the connecting groove. At this point, the first and second thermal insulation and soundproofing panels work together to provide thermal insulation and soundproofing at the connection between the two building walls.

[0012] Furthermore, a rotating groove is provided on the side wall of the main body of the building wall, and a receiving groove is provided on the inner wall of the rotating groove. The moving device includes a rotating rod rotatably disposed in the rotating groove and a steel wire rope with one end wound around the side wall of the rotating rod. The other end of the steel wire rope is fixed to the second thermal insulation and sound insulation board.

[0013] By adopting the above technical solution, when the two ends of the second T-shaped rod are respectively connected to the third T-shaped groove and the second thermal insulation and sound insulation board, and the two ends of the first T-shaped rod are respectively connected to the first T-shaped groove and the second T-shaped groove, the worker only needs to rotate the rotating rod to make the wire rope gradually wrap around the rotating rod, so that the second thermal insulation and sound insulation board and the first thermal insulation and sound insulation board move towards the rotating rod under the action of the wire rope, and then the second thermal insulation and sound insulation board finally presses against the inner wall of the connecting groove, thereby reducing the difficulty for the worker to connect the first thermal insulation and sound insulation board to the connecting groove.

[0014] Furthermore, a prismatic groove is provided on the side wall of the rotating rod, and a prismatic rod is slidably disposed in the prismatic groove. The end of the prismatic rod is fixed with a handle to reduce the difficulty for the operator to rotate the rotating rod.

[0015] By adopting the above technical solution, when the operator needs to rotate the rotating rod, the operator only needs to connect the prismatic rod and the prismatic groove and rotate the handle to make the rotating rod rotate with the handle, thereby reducing the difficulty for the operator to drive the second thermal insulation and sound insulation board.

[0016] Furthermore, a fixing groove is provided on the upper surface of the second thermal insulation and sound insulation board, and a blocking block is fixed on the inner top wall of the connecting groove, and the blocking block is connected to the fixing groove.

[0017] Furthermore, the cross-section of the blocking block is semi-circular.

[0018] By adopting the above technical solution, when workers need to connect two building wall structures, they must first ensure that the first and second thermal insulation and soundproofing panels form a single unit. To reduce the difficulty of connecting the first and second thermal insulation and soundproofing panels, workers must first move one end of the second thermal insulation and soundproofing panel outside the connecting groove. When the worker moves one end of the second thermal insulation and soundproofing panel outside the connecting groove, the blocking block connects with the fixing groove, thereby limiting the position of the second thermal insulation and soundproofing panel and reducing the probability that its position will change under external force. Subsequently, when the worker rotates the rotating rod, the force on the second thermal insulation and soundproofing panel exceeds the blocking capacity of the blocking block, and the second thermal insulation and soundproofing panel moves towards the rotating rod under the action of the steel wire rope.

[0019] Furthermore, a magnetic rod is installed on the side wall of the first thermal insulation and soundproofing board, and an iron sheet is fixed on the inner wall of the sliding groove.

[0020] By adopting the above technical solution, when the iron sheet presses against the magnetic rod, the magnetic rod and the iron sheet attract each other, thereby keeping the first thermal insulation and sound insulation board stable, thus reducing the probability of the first thermal insulation and sound insulation board separating from the sliding groove at this time.

[0021] Furthermore, the side wall of the rotating rod near the handle is flush with the side wall of the main building wall.

[0022] In summary, this utility model has the following beneficial effects: In this application, when workers need to connect two building wall bodies, they need to align the width of the two adjacent building wall bodies and move them closer to each other. This allows the stabilizing plate on one building wall body to move between the first and second mounting plates on the other building wall body, thus blocking the stabilizing plate. At this point, workers only need to connect the two ends of the first T-shaped rod to the first and second T-shaped grooves respectively to initially stabilize the two building wall bodies. Furthermore, the workers need to activate the drive assembly, which allows the first thermal insulation and soundproofing panel to connect with the connecting groove. This allows the first thermal insulation and soundproofing panel to shield the connection between the two main building walls, thereby improving the thermal insulation effect at the connection and reducing the difficulty of installing the first thermal insulation and soundproofing panel. Subsequently, the workers need to connect the fixing bolts with the first mounting plate, allowing the fixing bolts to penetrate the first mounting plate, the second mounting plate, the stabilizing plate, and the first thermal insulation and soundproofing panel, thus stabilizing the two main building walls. 2. In this application, when workers need to connect the first thermal insulation and soundproofing board to the connecting groove, they need to move the two main building wall structures closer together, so that the first and second thermal insulation and soundproofing boards abut against each other. Then, workers need to connect the two ends of the second T-shaped rod to the third T-shaped groove and the second thermal insulation and soundproofing board respectively, so that the first and second thermal insulation and soundproofing boards are connected and stabilized. Subsequently, workers need to continue moving the two main building wall structures closer together, so that the stabilizing plate abuts against one of the main building wall structures, thereby aligning the first T-shaped groove on one main building wall structure with the second T-shaped groove on the other. At this point, workers only need to connect the two ends of the first T-shaped rod to the first and second T-shaped grooves respectively to initially stabilize the two main building wall structures.

[0023] Furthermore, workers only need to activate the moving device to move the second thermal insulation and sound insulation board towards the connecting groove, causing the first thermal insulation and sound insulation board to move along with it, ultimately bringing the second thermal insulation and sound insulation board against the inner wall of the connecting groove. At this point, the first and second thermal insulation and sound insulation boards work together to provide thermal insulation and sound insulation at the connection between the two building wall structures. 3. In this application, when the two ends of the second T-shaped rod are respectively connected to the third T-shaped groove and the second thermal insulation and sound insulation board, and the two ends of the first T-shaped rod are respectively connected to the first T-shaped groove and the second T-shaped groove, the worker only needs to rotate the rotating rod to make the wire rope gradually wrap around the rotating rod, so that the second thermal insulation and sound insulation board and the first thermal insulation and sound insulation board move towards the rotating rod under the action of the wire rope, and then the second thermal insulation and sound insulation board finally presses against the inner wall of the connecting groove, thereby reducing the difficulty for the worker to connect the first thermal insulation and sound insulation board to the connecting groove.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-7As shown in the embodiment of this application, a thermal insulation and soundproof building wall is disclosed, including a building wall body 1, a first mounting plate 11, a second mounting plate 2, a stabilizing plate 21, a first T-shaped rod 4, a fixing bolt 41, a first thermal insulation and soundproofing plate 51, a driving assembly 6, a prismatic rod 81, a handle 82, a blocking block 84, a magnetic rod 85, and an iron sheet 9. The first mounting plate 11 and the second mounting plate 2 are both rectangular plate structures, and both are fixed to the side wall of one side of the building wall body 1. The stabilizing plate 21 is a rectangular plate structure, and is fixed to the side wall of the other side of the building wall body 1. The upper surface of the stabilizing plate 21 has a first T-shaped groove 3, and the upper surface of the building wall body 1 has a second T-shaped groove 31. The first T-shaped rod 4 is a rod structure with a T-shaped cross-section, and is slidably disposed within the first T-shaped groove 3. The fixing bolt 41 is installed on the side wall of the first mounting plate 11, and a sliding groove 5 is provided on the side wall of the main body of the building wall 1. The first thermal insulation and sound insulation board 51 is slidably installed in the sliding groove 5.

[0028] When the two ends of the second T-shaped rod 62 are respectively connected to the third T-shaped groove 63 and the second thermal insulation and sound insulation board 61, and the two ends of the first T-shaped rod 4 are respectively connected to the first T-shaped groove 3 and the second T-shaped groove 31, the workers only need to connect the fixing bolt 41 to the first mounting plate 11 to allow the fixing bolt 41 to penetrate the first mounting plate 11, the second mounting plate 2, the stabilizing plate 21 and the first thermal insulation and sound insulation board 51, thereby keeping the two building wall bodies 1 stable.

[0029] The side wall of the stabilizing plate 21 has a connecting groove 52 that matches the first thermal insulation and sound insulation plate 51. The driving assembly 6 is mounted on the stabilizing plate 21 and is used to drive the first thermal insulation and sound insulation plate 51. The driving assembly 6 includes a second thermal insulation and sound insulation plate 61, a second T-shaped rod 62, and a moving device 7. The second thermal insulation and sound insulation plate 61 has a plate-like structure and is slidably disposed in the connecting groove 52. The second T-shaped rod 62 has a rod-like structure with a T-shaped cross-section and is slidably connected to the upper surface of the second thermal insulation and sound insulation plate 61. The upper surface of the first thermal insulation and sound insulation plate 51 has a third T-shaped groove 63 that matches the second T-shaped rod 62.

[0030] When workers need to connect the first thermal insulation and soundproofing panel 51 to the connecting groove 52, they need to move the two building wall bodies 1 closer together, so that the first thermal insulation and soundproofing panel 51 and the second thermal insulation and soundproofing panel 61 can abut against each other. Then, workers need to connect the two ends of the second T-shaped rod 62 to the third T-shaped groove 63 and the second thermal insulation and soundproofing panel 61 respectively, so that the first thermal insulation and soundproofing panel 51 and the second thermal insulation and soundproofing panel 61 can be connected and stabilized. Next, workers need to continue moving the two building wall bodies 1 closer together, so that the stabilizing plate 21 abuts against one of the building wall bodies 1, so that the first T-shaped groove 3 on one building wall body 1 is aligned with the second T-shaped groove 31 on the other building wall body 1. At this point, workers only need to connect the two ends of the first T-shaped rod 4 to the first T-shaped groove 3 and the second T-shaped groove 31 respectively, so that the two building wall bodies 1 can be initially stabilized.

[0031] Furthermore, by simply activating the moving device 7, the second thermal insulation and soundproofing panel 61 can be moved closer to the connecting groove 52, causing the first thermal insulation and soundproofing panel 51 to follow the second thermal insulation and soundproofing panel 61, ultimately bringing the second thermal insulation and soundproofing panel 61 against the inner wall of the connecting groove 52. At this point, the first thermal insulation and soundproofing panel 51 and the second thermal insulation and soundproofing panel 61 cooperate with each other to provide thermal insulation and soundproofing at the connection between the two building wall bodies 1.

[0032] Both the first thermal insulation and sound insulation board 51 and the second thermal insulation and sound insulation board 61 are made by pressing together an insulation board and a sound insulation board. The insulation board can be made of inorganic thermal insulation materials such as foamed cement, foamed ceramics, rock wool, and traditional thermal insulation mortar, or it can be made of organic thermal insulation materials such as molded polystyrene board, extruded polystyrene board, phenolic foam, and rigid polyurethane foam, etc. The sound insulation board can be made of polyester fiber sound-absorbing cotton, which is available in the prior art.

[0033] A rotating groove 64 is formed on the side wall of the main building wall 1, and a receiving groove 65 is formed on the inner wall of the rotating groove 64. A moving device 7 is installed on the main building wall 1 to drive the second thermal insulation and soundproofing panel 61. The moving device 7 includes a rotating rod 71 and a steel wire rope 72. The rotating rod 71 is a round rod structure and is rotatably mounted in the rotating groove 64. One end of the steel wire rope 72 is wound around the side wall of the rotating rod 71, and the other end of the steel wire rope 72 is fixed to the second thermal insulation and soundproofing panel 61.

[0034] When the two ends of the second T-shaped rod 62 are respectively connected to the third T-shaped groove 63 and the second thermal insulation and sound insulation board 61, and the two ends of the first T-shaped rod 4 are respectively connected to the first T-shaped groove 3 and the second T-shaped groove 31, the worker only needs to rotate the rotating rod 71 to make the wire rope 72 gradually wrap around the rotating rod 71, so that the second thermal insulation and sound insulation board 61 and the first thermal insulation and sound insulation board 51 move closer to the rotating rod 71 under the action of the wire rope 72, and then make the second thermal insulation and sound insulation board 61 finally press against the inner wall of the connecting groove 52, thereby reducing the difficulty for the worker to connect the first thermal insulation and sound insulation board 51 and the connecting groove 52.

[0035] A prismatic groove 8 is provided on the side wall of the rotating rod 71. The prismatic rod 81 is a rod-shaped structure and is slidably disposed in the prismatic groove 8. A handle 82 is fixed to the end of the prismatic rod 81 to reduce the difficulty for the operator to rotate the rotating rod 71.

[0036] When the operator needs to rotate the rotating rod 71, the operator only needs to connect the prismatic rod 81 with the prismatic groove 8 and rotate the handle 82 to make the rotating rod 71 rotate with the handle 82, thereby reducing the difficulty for the operator to drive the second thermal insulation and sound insulation board 61.

[0037] The upper surface of the second thermal insulation and sound insulation board 61 is provided with a fixing groove 83. The blocking block 84 is a block structure with a semi-circular cross section. The blocking block 84 is fixed on the inner top wall of the connecting groove 52, and the blocking block 84 is connected to the fixing groove 83.

[0038] When workers need to connect two building wall structures 1, they must first ensure that the first thermal insulation and soundproofing panel 51 and the second thermal insulation and soundproofing panel 61 form a single unit. To reduce the difficulty of connecting the two panels, workers must first move one end of the second panel 61 outside the connecting groove 52. When this is done, the blocking block 84 connects to the fixing groove 83, thus limiting the position of the second panel 61 and reducing the probability of its position changing under external force. Subsequently, when the worker rotates the rotating rod 71, the force on the second panel 61 exceeds the blocking capacity of the blocking block 84, and the second panel 61 moves towards the rotating rod 71 under the action of the steel wire rope 72.

[0039] The magnet rod 85 is a rod-shaped structure and is installed on the side wall of the first thermal insulation and soundproofing plate 51. The iron sheet 9 is a sheet-shaped structure and is fixed to the inner wall of the sliding groove 5.

[0040] When the iron plate 9 presses against the magnet rod 85, the magnet rod 85 and the iron plate 9 attract each other, thereby stabilizing the first thermal insulation and sound insulation board 51 and reducing the probability of the first thermal insulation and sound insulation board 51 separating from the sliding groove 5 at this time.

[0041] To improve the stability of the rotating rod 71, the side wall of the rotating rod 71 near the handle 82 is flush with the side wall of the main body of the building wall 1.

[0042] The working principle of the thermal insulation and soundproof building wall in this embodiment is as follows: When workers need to connect two building wall bodies 1, they need to align the width of the two adjacent building wall bodies 1 and move them closer to each other. This allows the stabilizing plate 21 on one building wall body 1 to move between the first mounting plate 11 and the second mounting plate 2 on the other building wall body 1, thereby blocking the stabilizing plate 21. At this time, workers only need to connect the two ends of the first T-shaped rod 4 to the first T-shaped groove 3 and the second T-shaped groove 31 respectively to initially stabilize the two building wall bodies 1.

[0043] Furthermore, the operator needs to activate the drive assembly 6, which allows the first thermal insulation and soundproofing panel 51 to connect with the connecting groove 52 under the action of the drive assembly 6. This allows the first thermal insulation and soundproofing panel 51 to shield the connection between the two building wall bodies 1, thereby improving the thermal insulation effect at the connection between the two building wall bodies 1 and reducing the difficulty for the operator to install the first thermal insulation and soundproofing panel 51. Subsequently, the operator needs to connect the fixing bolt 41 with the first mounting plate 11, which allows the fixing bolt 41 to penetrate the first mounting plate 11, the second mounting plate 2, the stabilizing plate 21, and the first thermal insulation and soundproofing panel 51, thereby stabilizing the two building wall bodies 1.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
