Description

Technical Field

[0001] This application relates to the field of overhead panel technology, specifically an overhead panel. Background Technology

[0002] A raised, insulated roof refers to a roof structure where sintered clay bricks or precast reinforced concrete slabs are erected at a certain height above the waterproof layer, utilizing airflow to accelerate heat dissipation and achieve insulation. Before constructing the raised slabs, the waterproof layer must be inspected to ensure it is qualified, leak-free, and free of water accumulation. During construction, care should be taken to avoid damaging the waterproof layer during the transportation of bricks (piers) and slabs, especially for flexible waterproof layers, where effective protective measures are necessary. Before constructing the piers, the roof surface must be thoroughly cleaned, ensuring no mortar, broken bricks, or debris remain. Marking lines according to the raised slab dimensions is essential, and the base of the brick piers must be grouted or have a reinforcing insulating layer.

[0003] An existing patent (publication number: CN220414738U) discloses a prefabricated dry-construction sound insulation overhead panel, including a thermal insulation and sound insulation board. The side of the thermal insulation and sound insulation board has a first arc-shaped surface, which is slidably connected to a fixing block. The bottom end of the fixing block is connected to a height adjustment structure, and the top end of the fixing block has a threaded groove for threaded connection with a bolt. The end of the thermal insulation and sound insulation board near the fixing block has a second arc-shaped surface, and the top end of the first arc-shaped surface has a limit groove. The bottom end of the bolt is connected to a limit ring, which is slidably connected to the limit groove. By connecting the bolts to the fixing block, four thermal insulation and sound insulation boards are fixed in place. Aligning the limit ring with the limit groove strengthens the thermal insulation and sound insulation boards and also provides waterproofing, preventing water from entering through gaps and corroding the bolts and connecting structure, thus preventing the bolts from being difficult to remove. The height of the support plate can be adjusted by a hydraulic cylinder to meet different installation height requirements. This effectively strengthens the thermal insulation and sound insulation boards and prevents vertical movement. Waterproof rings can prevent water intrusion, prevent corrosion of bolts and connecting parts, and also provide a certain buffering effect.

[0004] While the above-mentioned device facilitates the fixed installation of four thermal insulation and soundproof panels and the adjustment of the height of the support plate, the hydraulic cylinder requires a hydraulic pump, pipelines and control system, resulting in a high overall cost. It also requires regular replacement of hydraulic oil and seals, and the construction site is prone to oil pollution and hydraulic system leaks. Long-term vibration or dusty environments may cause malfunctions. Therefore, an overhead panel is provided. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an overhead panel that can significantly reduce costs while avoiding the environmental pollution risks associated with hydraulic systems.

[0006] To achieve the above objectives, this application provides the following technical solution: an overhead panel, comprising a thermal insulation and sound insulation panel, a connecting frame, and a supporting mechanism. The connecting frame is disposed at the lower end of the thermal insulation and sound insulation panel, and the supporting mechanism is disposed at the lower end of the connecting frame. The supporting mechanism includes a housing, a rotating shaft rotatably connected to the side of the housing, a worm gear fixedly connected to the left end of the rotating shaft, a rotating cap fixedly connected to the right end of the rotating shaft, the left end of the worm gear rotatably connected inside the housing, a worm wheel meshing with the surface of the worm gear, the upper end of the worm wheel rotatably connected inside the housing, a threaded post disposed at the lower end of the worm wheel, a movable block disposed at the lower end of the threaded post, the threaded post being threadedly connected inside the movable block, and a mounting base fixedly connected to the lower end of the movable block.

[0007] The above solution, by setting up a support mechanism, allows workers to adjust the height of the support plate by rotating the rotating cap, which in turn drives the worm gear to rotate. With the cooperation of the worm gear and worm wheel, the support plate is moved up and down to the appropriate position, facilitating installation at different heights. By replacing the hydraulic cylinder with the worm gear and worm wheel, costs can be significantly reduced and reliability improved, while avoiding the environmental pollution risks of hydraulic systems. This solution is particularly suitable for prefabricated building scenarios that require frequent height adjustments or long-term exposure to dusty environments, aligning with the trends of green construction and industrialized building.

[0008] Furthermore, the support mechanism consists of four sets, arranged in a rectangular shape at the lower end of the thermal insulation and soundproofing board. The side of the housing is fixedly connected with a clip, which cooperates with the rotating shaft.

[0009] With the above scheme, the four support points are symmetrically distributed in a rectangle, which can evenly transfer the weight of the thermal insulation and sound insulation board to the foundation, reduce local stress concentration, and avoid structural deformation or cracking caused by single-point overload.

[0010] Furthermore, a support plate is fixedly connected to the upper surface of the housing, a fixing block is fixedly connected to the upper surface of the support plate, and a protrusion is connected to the side of the support plate, the protrusion being slidably connected to the side of the connecting frame.

[0011] With the above solution, the sliding connection is easy to install and disassemble. The protrusion on the side of the support plate matches the sliding groove of the connecting frame. During installation, it is only necessary to push it in along the slide, without the need for precision alignment tools, which reduces the difficulty of manual operation.

[0012] Furthermore, the active block has scale lines on its front side.

[0013] The above scheme provides intuitive displacement or angle indications, allowing operators to directly judge the amount of movement of the moving block by observing the scale values.

[0014] Furthermore, the thermal insulation and sound insulation board has a first arc-shaped surface on its side, which is slidably connected to a fixing block. A bolt is provided at the upper end of the fixing block, and a threaded groove is provided at the top of the fixing block to be threadedly connected to the bolt. The thermal insulation and sound insulation board has a second arc-shaped surface at one end near the fixing block.

[0015] With the above solution, the sliding connection between the first arc-shaped surface and the fixed block forms a self-guiding structure, enabling rapid alignment without additional tools during installation. During operation, simply push the fixed block along the arc-shaped trajectory to automatically correct horizontal and vertical deviations, reducing manual calibration time.

[0016] Furthermore, a limiting groove is formed at the top of the first arc-shaped surface, and a limiting ring is connected to the bottom of the bolt. The limiting ring is slidably connected to the limiting groove.

[0017] Through the above scheme, the sliding fit between the limiting ring and the limiting groove forms a mechanical guide track, ensuring that the bolt can only be screwed in along the preset path, avoiding thread mis-threading or stripping caused by angular deviation.

[0018] Furthermore, the upper part of the bolt is slidably connected to the second arc-shaped surface, the height of the fixing block is lower than that of the first arc-shaped surface, and a waterproof ring is connected to the bottom end of the bolt.

[0019] The above solution uses a waterproof ring to prevent water intrusion, thus preventing corrosion of the bolts and connecting parts, while also providing a certain buffering effect.

[0020] Furthermore, a rubber ring is connected to the top of the connecting frame, and the rubber ring is set at the upper end of the thermal insulation and soundproofing board.

[0021] The above solution allows the rubber ring to act as a buffer, reducing the vibration of the thermal insulation and soundproofing panel.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This type of overhead panel, through the setting of a support mechanism, allows workers to adjust the height of the support panel by rotating a rotating cap, which in turn drives a worm gear to rotate. With the cooperation of the worm gear and worm wheel, the support panel is moved up and down to the appropriate position, facilitating installation at different heights. By replacing hydraulic cylinders with worm gears and worm wheels, costs can be significantly reduced and reliability improved, while avoiding the environmental pollution risks of hydraulic systems. This solution is particularly suitable for prefabricated building scenarios that require frequent height adjustments or long-term exposure to dusty environments, aligning with the trends of green construction and industrialized building.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 3 and Figure 5In this embodiment, an overhead panel includes a thermal insulation and soundproof panel 1, a connecting frame 2, and a support mechanism 3. The connecting frame 2 is located at the lower end of the thermal insulation and soundproof panel 1, and the support mechanism 3 is located at the lower end of the connecting frame 2. The support mechanism 3 includes a housing 301, a rotating shaft 302 rotatably connected to the side of the housing 301, a worm gear 303 fixedly connected to the left end of the rotating shaft 302, and a rotating cap 305 fixedly connected to the right end of the rotating shaft 302. The left end of the worm gear 303 is rotatably connected inside the housing 301, and a worm wheel 304 is meshed on the surface of the worm gear 303. The upper end of the worm wheel 304 is rotatably connected inside the housing 301, and a threaded post 306 is provided at the lower end of the worm wheel 304. A movable block 307 is provided at the lower end of the threaded post 306. The threaded connection is inside the movable block 307, and the lower end of the movable block 307 is fixedly connected to the mounting base 309. By setting the support mechanism 3, when the staff needs to adjust the height of the support plate 4, the staff rotates the rotating cap 305, which in turn drives the worm gear 303 to rotate. With the cooperation of the worm gear 303 and the worm wheel 304, the support plate 4 is moved up and down to the appropriate position, which is convenient for the needs of different height installation. By replacing the hydraulic cylinder with the worm gear 303 and the worm wheel 304, the cost can be significantly reduced and the reliability can be improved. At the same time, the environmental pollution risk of the hydraulic system is avoided. This solution is especially suitable for prefabricated building scenarios that require frequent height adjustment or long-term exposure to dusty environments, which is in line with the trend of green construction and industrialized construction.

[0034] Please see Figure 1 , Figure 3 and Figure 4 The support mechanism 3 consists of four sets, arranged in a rectangular shape at the lower end of the thermal insulation and sound insulation board 1. A clamp 308 is fixedly connected to the side of the housing 301, cooperating with the rotating shaft 302. A support plate 4 is fixedly connected to the upper surface of the housing 301, and a fixing block 5 is fixedly connected to the upper surface of the support plate 4. A protrusion is connected to the side of the support plate 4, and the protrusion is slidably connected to the side of the connecting frame 2. A scale line 310 is provided on the front of the movable block 307. The four support points are symmetrically distributed in a rectangular shape, which can evenly transfer the weight of the thermal insulation and sound insulation board to the foundation, reducing local stress concentration and avoiding structural deformation or cracking caused by single-point overload. The sliding connection facilitates installation and disassembly. The protrusion on the side of the support plate 4 cooperates with the sliding groove of the connecting frame 2. During installation, it only needs to be pushed in along the slide, without the need for precision alignment tools, reducing the difficulty of manual operation. The scale line 310 provides intuitive displacement or angle indication, allowing the operator to directly judge the amount of movement of the movable block by observing the scale value.

[0035] Please see Figure 1 , Figure 5 and Figure 6The thermal insulation and sound insulation board 1 has a first arc-shaped surface 7 on its side, which is slidably connected to the fixing block 5. The fixing block 5 has a bolt 6 on its upper end, and a threaded groove on its top end that is threaded to the bolt 6. The thermal insulation and sound insulation board 1 has a second arc-shaped surface 9 near the fixing block 5. The top end of the first arc-shaped surface 7 has a limit groove 8. The bottom end of the bolt 6 is connected to a limit ring 601, which is slidably connected to the limit groove 8. The upper part of the bolt 6 is slidably connected to the second arc-shaped surface 9. The fixing block 5 is lower than the first arc-shaped surface 7. The bottom end of the bolt 6 is connected to a waterproof ring 602. The top end of the connecting frame 2 is connected to a rubber ring 10, which is located on the upper end of the thermal insulation and sound insulation board 1. The sliding connection between the first arc-shaped surface 7 and the fixing block 5 forms a self-guiding structure, which allows for quick alignment without additional tools during installation. During operation, simply push the fixing block 5 along the arc trajectory to automatically correct horizontal and vertical deviations, reducing manual calibration time. The sliding fit between the limiting ring 601 and the limiting groove 8 forms a mechanical guide track, ensuring that the bolt 6 can only be screwed in along the preset path, avoiding thread mis-threading or stripping due to angular deviation. The waterproof ring 602 can isolate water intrusion, preventing corrosion of the bolt 6 and the connecting parts, while also providing a certain buffering effect. The rubber ring 10 can also act as a buffer, reducing the vibration of the thermal insulation and sound insulation board 1.

[0036] In this embodiment, by setting up the support mechanism 3, when the staff needs to adjust the height of the support plate 4, the staff rotates the rotating cap 305, which in turn drives the worm gear 303 to rotate. With the cooperation of the worm gear 303 and the worm wheel 304, the support plate 4 is moved up and down to a suitable position, which is convenient for the needs of different height installations. By replacing the hydraulic cylinder with the worm gear 303 and the worm wheel 304, the cost can be significantly reduced and the reliability can be improved. At the same time, the environmental pollution risk of the hydraulic system is avoided. This solution is especially suitable for prefabricated building scenarios that require frequent height adjustments or long-term exposure to dusty environments, which is in line with the trend of green construction and industrialized construction.

[0037] The working principle of the above embodiment is as follows: When using this device, the four thermal insulation and sound insulation panels 1 are fixedly installed by connecting the bolts 6 to the fixing block 5. The limiting ring 601 corresponds to the limiting groove 8, which can strengthen the thermal insulation and sound insulation panels 1 and also play a role in waterproofing. The operator rotates the rotating cap 305, which in turn drives the worm gear 303 to rotate. With the cooperation of the worm gear 303 and the worm wheel 304, the support plate 4 is moved up and down to a suitable position to meet the needs of different height installations. The waterproof ring 602 can prevent water from entering and prevent corrosion of the bolts 6 and the connecting parts, while also playing a certain buffering role. The connecting frame 2 can strengthen the top thermal insulation and sound insulation panel 1. At the same time, when the height of the support plate 4 is adjusted, it can also keep the two opposite support plates 4 at the same height. The sliding connection also facilitates installation and disassembly. The rubber ring 10 can play a buffering role and reduce the vibration of the thermal insulation and sound insulation panel 1.
