Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a membrane structure prestressed graded tensioning device, including a main rod 1 for connecting various components. A non-slip handle 11 is fixedly connected to the bottom of the main rod 1, with anti-slip ridges on its exterior. An auxiliary handle 12 is fixedly connected to the rear side of the main rod 1 for user gripping. A locking block 13 is fixedly connected to the front side of the main rod 1, which can be locked onto one side of the membrane structure mounting frame, making it easier for the user to ensure a stable grip during tensioning. An obtuse-angled groove is provided on the front side of the locking block 13, allowing it to be locked onto support columns of different thicknesses. A rubber pad is fixedly connected inside the obtuse-angled groove for anti-slip purposes. A tensioning mechanism is installed on the upper part of the main rod 1, used for graded prestressing tensioning during membrane structure installation. The tensioning sections need to be loaded step-by-step to the design value. According to the design-required prestress value, the fixed component 3 is moved multiple times via the moving component 2, thereby gradually increasing the membrane tensioning distance and avoiding excessive stress in a single tensioning operation that could damage the membrane structure, ultimately achieving the designed prestress.

[0019] Furthermore, the tensioning mechanism includes a fixing component 3, which is used to fix the edge of the membrane to facilitate membrane tensioning. The fixing component 3 includes a vertical plate 31, which is used to connect various components. The front side of the vertical plate 31 has two sliding grooves 311, and the front side of the vertical plate 31 is provided with two clamping plates 33. The rear side of each clamping plate 33 is fixedly connected to a slider 331, which is slidably connected to the clamping plate 33. The connection between the vertical plate 31 and the clamping plate 33 can be realized through the mutual cooperation between the sliding grooves 311 and the sliders 331. The rear side of the vertical plate 31 is fixedly connected to an electric telescopic rod 32, which is used to provide power to the fixing component 3. The output end of the electric telescopic rod 32 passes through and is movably connected to the upright plate 31. A connecting block 36 is fixedly connected to the front side of the output end of the electric telescopic rod 32, which is used to connect various components. A support rod 37 is hinged between the connecting block 36 and the clamping plate 33, which is used to control the movement of the clamping plate 33. Limiting blocks 34 are fixedly connected to the sides of the two clamping plates 33 that are close to each other, which are used to limit the edge of the membrane. Anti-slip pads 35, which can be made of rubber, are fixedly connected to the sides of the two limiting blocks 34 that are close to each other. They are provided with anti-slip grooves. A hook 38 is fixedly connected to the lower front side of the upright plate 31, which can be used for limiting and tensioning membranes with annular openings.

[0020] Furthermore, the tensioning mechanism also includes a movable component 2, which is used to adjust the position of the fixed component 3 to prestress the membrane structure. The movable component 2 includes a housing 21, which is used to connect the various components. The housing 21 is fixedly connected to the top of the main rod 1. A motor 22 is fixedly connected to the rear side of the housing 21, which is used to drive the screw 23 to rotate. The output end of the motor 22 is fixedly connected to the screw 23 via a push rod coupling, which is used to adjust the position of the movable block 24. The screw 23 passes through and is rotatably connected to the housing 21. The movable block 24 is slidably connected inside the housing 21. The screw 23 passes through and is threadedly connected to the movable block 24. The upright plate 31 is fixedly connected to the movable block 24.

[0021] Working principle: During membrane structure installation, the installation method involves first aligning the center point and then expanding outwards. Once aligned, the membrane is pre-fixed to its designed position on the mounting frame. Based on the center reference point, a tensioning mechanism is used to temporarily tighten and position the membrane in different areas. When using the tensioning mechanism, the motor 22 controls the screw 23 to rotate, causing the moving block 24 to move the fixing component 3 to the front of the outer shell 21. Then, the clamping block 13 of the tensioning device is engaged on one side of the mounting frame column. Finally, the edge requiring tension is placed between the two limiting blocks 34. The electric telescopic rod 32 is then activated, causing the connecting block 3 to move accordingly. 6. Movement occurs. When the connecting block 36 moves, it will drive the support rod 37 connected to it. The support rod 37 will drive the two clamping plates 33 connected to it to move closer to each other. The limiting block 34 fixed to the clamping plate 33 will move accordingly, so that the two anti-slip pads 35 can clamp the edge of the membrane. If the membrane is provided with a ring hole, the ring hole can be directly hung on the hook 38. Then, the screw 23 is reversed by the motor 22. The screw 23 will drive the moving block 24 to move backward, thereby driving the vertical plate 31 fixed to it to move. The fixing component 3 will move as a whole, and drive the edge of the membrane held by it to be prestressed in stages until it is tensioned to a suitable degree, and the position of the membrane is fixed.

[0022] Additionally, it should be noted that components not described in detail in this article are existing technologies.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
