However, actual concrete is a "surface load," and single-point contact loading can lead to significant deviations between the stress on the support system and the actual working conditions. Furthermore, there are various types of formwork, including irregularly shaped formwork and temporarily repaired old formwork. The top surfaces of these formworks are uneven, and if a fixed-length pressing structure is used, some parts will be suspended, resulting in uneven transmission of pressing force and even misjudging the stability of the support. Therefore, there is an urgent need for a formwork support stability testing device to solve these problems. Utility Model Content

[0014] 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.

[0015] Please see Figures 1-7 This utility model provides a stability testing device for building formwork support, including a testing frame 4, a support plate 5 inside the testing frame 4, and the support plate 5 being movably connected to the testing frame 4. A guide rod 3 is fixed on the top surface of the support plate 5 and passes through the top surface of the testing frame 4. A hydraulic rod 2 is fixed on the top surface of the testing frame 4 and its output end is fixedly connected to the top surface of the support plate 5. Movable grooves 15 are arrayed on the top surface of the support plate 5 and pass through the support plate 5 respectively. It also includes a support component 1, which is set in the movable grooves 15 to enhance the stability during building formwork testing. Specifically, before testing, the support component 1 will first make contact with the top surface of the building formwork for positioning, and then apply downward pressure under the action of the hydraulic rod 2. During the pressure application process, there are multiple stable contact points between the support component 1 and the building surface, and the pressure between each contact point is the same. These designs enable the device to perform support stability testing on various types of building formwork, enhance the adaptability of the device, and make the downward pressure distribution during testing more uniform, thereby improving the accuracy of the device's testing. Specifically, driven by the hydraulic rod 2, the support plate 5 can move downward with the support assembly 1 to contact the building template, and the guide rod 3 makes the movement of the support plate 5 more stable. The support assembly 1 includes a movable plate, and the movable rod 102 is movably connected to the movable groove 15. The top and bottom ends of the movable rod 102 are respectively fixed with limit blocks 101. The surface of the movable rod 102 is provided with a return spring 103, and the two ends of the return spring 103 are respectively fixedly connected to the limit block 101 and the support plate 5. Specifically, when the support component 1 moves downward and contacts the building template, the limiting blocks 101 at the bottom of all the movable rods 102 need to contact the building template. During the contact process, because the top surface of the building template is uneven, the positions of the movable rods 102 in the movable groove 15 are different. However, under the action of the return spring 103, the limiting blocks 101 at the bottom of the movable rods 102 can all contact the top surface of the building template. A pressure sensor 104 is fixed on the bottom surface of the limiting block 101. A fixed seat 105 is provided on the bottom surface of the pressure sensor 104. A first rotating groove 110 and a second rotating groove 111 are respectively opened on the surface of the fixed seat 105. A first rotating shaft 106 and a second rotating shaft 107 are respectively provided in the first rotating groove 110 and the second rotating groove 111. A first support frame 108 is fixed on the surface of the first rotating shaft 106, and a second support frame 109 is fixed on the surface of the second rotating shaft 107. Specifically, during the descent of the support component 1, both the first support frame 108 and the second support frame 109 can rotate along the first rotation axis 106 and the second rotation axis 107, so each support component 1 has at least two positions in contact with the building template. The inner wall of the movable groove 15 is inlaid with anti-slip pads 11. The side of the support plate 5 is provided with a movable bracket 13, which passes through the side of the movable groove 15 and is movably connected to the support plate 5. Locking pads 12 are fixed at both ends of the movable bracket 13. The anti-slip pads 11 and locking pads 12 are made of rubber thermoplastic. A locking motor 10 is fixed on the surface of the movable bracket 13. A locking screw 14 is fixed at the output end of the locking motor 10 and is threadedly connected to the support plate 5. Specifically, when the support plate 5 and the support component 1 are in contact with the building template, under the drive of the locking motor 10, the locking screw 14 moves with the movable bracket 13 in the support plate 5, and then the locking pad 12 moves towards the anti-slip pad 11 to clamp the movable rod 102, thereby fixing the position of the support component 1. The inner side of the detection frame 4 is provided with a telescopic groove 7, and the telescopic groove 7 is axially symmetrical about the detection frame 4. An adjusting threaded rod 6 is provided in the telescopic groove 7, and the adjusting threaded rod 6 passes through the side of the detection frame 4. The adjusting threaded rod 6 is threadedly connected to the detection frame 4. A displacement sensor 8 is fixed at one end of the adjusting threaded rod 6. A ball 9 is provided at one end of the displacement sensor 8, and the ball 9 is movably connected to the displacement sensor 8. Specifically, before inspecting the building formwork, the building formwork is placed inside the inspection frame 4. Then, the adjusting threaded rods 6 on both sides are rotated so that the displacement sensor 8 in the expansion groove 7 protrudes and contacts the building formwork. When the building formwork moves under pressure, the displacement sensor 8 can detect the movement signal. The ball bearing 9 facilitates the detection of the movement state of the building formwork in different directions.

[0016] Working principle: Driven by the hydraulic rod 2, the support plate 5 can move downward with the support assembly 1 to contact the building template. The guide rod 3 makes the movement of the support plate 5 more stable. When the support assembly 1 moves downward to contact the building template, the limiting blocks 101 at the bottom of all the movable rods 102 need to contact the building template. During the contact process, due to the unevenness of the top surface of the building template, the positions of the movable rods 102 in the movable groove 15 are different. However, under the action of the return spring 103, the limiting blocks 101 at the bottom of the movable rods 102 can all contact the top surface of the building template. During the descent of the support assembly 1, the first support frame 108 and the second support frame 109 can rotate along the first rotation axis 106 and the second rotation axis 107. Therefore, each support assembly 1 has at least two positions in contact with the building template. When the support plate 5 and the support assembly 1 are in contact with the building template, the locking screw 14 moves with the movable bracket 13 in the support plate 5 under the drive of the locking motor 10. Then the locking pad 12 moves towards the anti-slip pad 11 to clamp the movable rod 102, thus fixing the position of the support assembly 1. Before inspecting the building template, the building template is placed in the inspection frame 4. Then the adjusting screw rods 6 on both sides are rotated so that the displacement sensor 8 in the expansion groove 7 protrudes and contacts the building template. When the building template moves under pressure, the displacement sensor 8 can detect the movement signal. The ball bearing 9 facilitates the detection of the movement state of the building template in different directions. Before testing, the support component 1 will first make contact with the top surface of the building formwork for positioning. Then, under the action of the hydraulic rod 2, it will be loaded and pressed downward. During the pressing process, there are multiple stable contact points between the support component 1 and the building surface, and the pressure between each contact point is the same. These designs enable the device to perform support stability testing on various types of building formwork, enhance the adaptability of the device, and make the downward pressure distribution during testing more uniform, thereby improving the accuracy of the device's testing.
