Description

Technical Field

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

[0002] Precast insulated wall panels are a high-efficiency and environmentally friendly building insulation material, boasting advantages such as high production precision, fast construction speed, good durability, and significant thermal insulation effect. They are suitable for the thermal insulation needs of various buildings and are an important component of prefabricated buildings. Precast insulated wall panels typically consist of inner leaf walls, insulation boards and connectors, and outer leaf walls, forming a sandwich-like structural form.

[0003] Chinese patent CN220768604U discloses a precast insulated sandwich wall panel. This utility model connects the outer wall panel and inner wall panel with the insulation board through the setting of structures such as inserts and slots. The connection is enhanced by the setting of structures such as slots, receiving grooves, springs, limiting blocks, traction ropes, rotating shafts and rotating wheels, which facilitates the installation and disassembly of the outer wall panel and inner wall panel with the insulation board, improves the efficiency of disassembly and assembly, and reduces labor intensity.

[0004] However, the device still has shortcomings: the rotating wheel of the device is located on the side of the inner wall panel, and it can only be operated from the side. After the insulation wall panels are spliced, the gap between two adjacent insulation wall panels is very small, which is not enough to provide enough space for the driving wheel. As a result, the device cannot quickly and independently disassemble the outer wall panel and inner wall panel at any position. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a prefabricated insulated wall panel.

[0006] The technical solution of this utility model is as follows: a prefabricated insulated wall panel, including an inner wall panel, a groove is provided on the inner wall panel, a limiting frame is provided in the groove, two sets of insertion holes are symmetrically provided on the limiting frame, and a sliding groove is provided on the limiting frame.

[0007] The slider consists of two sets of sliders symmetrically and slidably arranged in the groove. Wedge-shaped blocks are set on the sliders, and each wedge-shaped block is inserted into the corresponding side of the insertion hole. A rack is set on the side of the two sliders that are close to each other.

[0008] The spline shaft is rotatably mounted on the limit frame. The spline shaft is coaxially connected to the gear, which is located between the racks on both sides and meshes with both racks.

[0009] A movable plate, one end of which is inserted into the spline shaft and slides radially therein, and the end of the movable plate extending out of the spline shaft is connected to a disc. The end of the disc away from the movable plate is offset from its axis and a positioning pin is set thereoff. A tensioning component for tensioning the movable plate is set inside the spline shaft.

[0010] The exterior wall panel is provided with several plug rods that are adapted to each plug hole. The plug rods are provided with slots that are adapted to wedge-shaped blocks. A turntable is rotatably provided on the exterior wall panel. A circular groove is provided on the turntable. The turntable is inserted into the circular groove and rotates coaxially with it. A positioning groove communicating with the circular groove is provided on the turntable.

[0011] Preferably, a support groove is provided on the inner wall panel, and a sealing ring adapted to the support groove is provided on the outer wall panel.

[0012] Preferably, an annular groove is provided between the outer wall of the limiting frame and the side wall of the groove, and an annular sound insulation plate is provided in the annular groove, with the annular sound insulation plate attached to the outer wall panel.

[0013] Preferably, a plurality of slide rods A are provided in the groove, the slide rods A penetrate vertically through the slider and are slidably connected to it, and springs A are sleeved on the slide rods A, with the two ends of the springs A abutting against the sliders on both sides respectively.

[0014] Preferably, a vertical groove A is provided inside the spline shaft, a fixed plate is provided inside the opening of the vertical groove A, a vertical groove B is provided on the movable plate, and the fixed plate is located inside the vertical groove B and is slidably connected to its inner wall.

[0015] Preferably, the tensioning assembly includes a slide bar B and a spring B. The two ends of the slide bar B are connected to the bottom surface of the vertical groove A and the lower end surface of the fixing plate, respectively. The spring B is sleeved on the slide bar B, and the two ends of the spring B abut against the fixing block and the bottom surface of the vertical groove B, respectively.

[0016] Preferably, an iron plate is placed on the disc.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By designing separate inner and outer wall panels, the outer wall panel can be replaced individually after damage, reducing costs. The outer and inner wall panels are connected by wedge-shaped clips and insert rods, facilitating the fixation of the outer wall panel. A mechanism involving gears, racks, splined shafts, movable plates, tensioning components, discs, and positioning pins allows rotation of the disc to drive the splined shaft, causing the rack to retract the slider and disengage the wedge-shaped clips from the slots on the insert rods. Simultaneously, a turntable on the outer wall panel features circular grooves and positioning slots. Initially, both the disc and positioning pin are located in the circular grooves, with the positioning pin aligned but not yet inserted. However, attaching a magnet to the turntable attracts the disc, causing the positioning pin to insert into the positioning slot. Rotating the turntable then rotates the disc, retracting the wedge-shaped clips. This connection structure allows for the individual disassembly of any outer wall panel, making operation simple and convenient. Attached Figure Description

[0025] Example 1

[0026] like Figures 1-5As shown, this utility model proposes a prefabricated insulated wall panel, including an inner wall panel 1, sliders 4, a spline shaft 9, a movable plate 11, and an outer wall panel 16. The inner wall panel 1 has a groove 101 and a support groove 102. A limiting frame 2 is installed within the groove 101, and two sets of insertion holes 201 are symmetrically arranged on the limiting frame 2, with a sliding groove 202 also provided. Two sets of sliders 4 are symmetrically and slidably arranged within the sliding groove 202. Wedge-shaped blocks 5 are installed on the sliders 4, each wedge-shaped block 5 being inserted into the corresponding insertion hole 201. A rack 8 is installed on the side of the sliders 4 that is close to each other. Several sliding rods A6 are installed within the groove 101, with each sliding rod A6 vertically penetrating the slider 4 and slidably connected to it. Springs A7 are sleeved on the sliding rods A6, with both ends of the springs A7 abutting against the sliders 4 on both sides. The spline shaft 9 is rotatably mounted on the limit frame 2. The spline shaft 9 is coaxially connected to the gear 10, which is located between and meshes with the racks 8 on both sides. A vertical groove A91 is provided inside the spline shaft 9, and a fixed plate is provided inside the opening of the vertical groove A91. One end of the movable plate 11 is inserted into the spline shaft 9 and slides radially therein. A vertical groove B111 is provided on the movable plate 11, and the fixed plate is located in the vertical groove B111 and is slidably connected to its inner wall. One end of the movable plate 11 extending out of the spline shaft 9 is connected to a disc 14. An iron plate or magnet is provided on the disc 14. A positioning pin 15 is provided off-center from the axis at the end of the disc 14 away from the movable plate 11, and a tensioning component for tensioning the movable plate 11 is provided inside the spline shaft 9. The tensioning assembly includes a slide bar B12 and a spring B13. The two ends of the slide bar B12 are connected to the bottom surface of the vertical groove A91 and the lower end surface of the fixing plate, respectively. The spring B13 is sleeved on the slide bar B12, and the two ends of the spring B13 abut against the bottom surface of the fixing block and the vertical groove B111, respectively. Both the exterior wall panel 16 and the interior wall panel 1 are precast panels made of thermal insulation material. The exterior wall panel 16 is provided with a sealing ring 161 that matches the support groove 102. The exterior wall panel 16 is provided with several insertion rods 17 that match each insertion hole 201. The insertion rods 17 are provided with slots 171 that match the wedge-shaped locking block 5. A turntable 18 is rotatably provided on the exterior wall panel 16. The turntable 18 is provided with a circular groove 181 that matches the disc 14. The turntable 18 is also provided with a positioning groove 182 that communicates with the circular groove 181. When the interior wall panel 1 and the exterior wall panel 16 are tightly connected, the disc 14 and the positioning pin 15 are both located in the circular groove 181. The positioning pin 15 is aligned with the positioning groove 182, but the positioning pin 15 has not yet been inserted into the positioning groove 182. At the same time, the turntable 18 is provided with an indicator arrow to indicate the position of the positioning groove 182.

[0027] In this embodiment, during installation, the inner wall panel 1 is first fixed to the wall. Then, the circular groove 181 on the outer wall panel 16 is aligned with the disc 14 and snapped onto the inner wall panel 1. During this process, each insert rod 17 on the outer wall panel 16 is inserted into the corresponding side insertion hole 201, and each wedge-shaped locking block 5 adaptively extends and retracts and snaps into the corresponding side insertion rod 17's slot 171. When it is necessary to remove and replace the outer wall panel 16 at any position, first rotate the turntable 18 until the indicator arrow points towards the positioning pin 15 (the initial position of the positioning pin 15 is the same). Then, attach the magnet to the turntable 18 and attach the suction cup. Use the magnet to attract the disc 14, and the disc 14 slides and makes the positioning pin 14 slide. Pin 15 is inserted into positioning groove 182. At this time, rotating turntable 18 can drive gear 10 to rotate through positioning pin 15, disc 14, movable plate 11 and spline shaft 9. The rotation of gear 10 drives the racks 9 on both sides to slide, so that the sliders 4 on both sides move closer together and the wedge-shaped block 5 is disengaged from the slot 171. The outer wall panel 16 can be removed by suction cup. After the outer wall panel 16 is removed, spring A7 and spring B13 release potential energy, slider 4 returns to its original position, and movable plate 11 returns to its original position. After the new outer wall panel 16 is installed in place, disc 14 and positioning pin 15 are both located in circular groove 181, and positioning pin 15 is aligned with positioning groove 182, but positioning pin 15 has not yet been inserted into positioning groove 182.

[0028] Example 2

[0029] like Figure 2 and Figure 5 As shown, the prefabricated insulated wall panel proposed in this utility model, compared with the first embodiment, has an annular groove between the outer wall of the limiting frame 2 and the side wall of the groove 101, and an annular sound insulation board 3 is provided in the annular groove, and the annular sound insulation board 3 is attached to the outer wall panel 16.

[0030] In this embodiment, by adding sound insulation cotton in the annular groove, the sound insulation performance of the thermal insulation wall panel can be improved. The sound insulation cotton also has a certain thermal insulation performance. When used in conjunction with the thermal insulation characteristics of the outer wall panel 16 and the inner wall panel 1, the thermal insulation performance of the wall panel can be enhanced.
