Description

Technical Field

[0001] This utility model relates to the field of insulation board anchorage force testing technology, specifically to a device for testing the anchorage force of building exterior wall insulation boards. Background Technology

[0002] Currently, in the field of anchorage force testing of building exterior wall insulation boards, commonly used testing devices typically include core components such as a mounting base, clamping components, nuts, and a hydraulic cylinder for a pulling machine. During use, the operator first aligns the clamping components with the rivets or riveted reinforcing bars to be tested on the insulation board, adjusts the position of the clamping components to clamp the target component, and then secures the clamping components with the nuts threaded onto them. Simultaneously, the position of the nuts is adjusted according to the testing requirements to control the advance and retreat of the hydraulic cylinder for the pulling machine. Finally, the hydraulic cylinder for the pulling machine, installed on the side of the mounting base, is activated. The hydraulic cylinder pushes the clamping components away from the insulation board, causing the rivets or reinforcing bars to move synchronously. The anchorage force is tested through the output force of the hydraulic cylinder.

[0003] However, existing testing devices have significant shortcomings in practical applications: most rely solely on the clamping force of the clamping components on the rivets and reinforcing bars, or simple mechanical contact, to maintain the position of the mounting base, lacking a dedicated stabilizing structure. During pull-out testing, the mounting base is prone to displacement or loosening due to the continuous pull-out force, causing relative positional shifts between the clamping components and the rivets and reinforcing bars being tested. This prevents the pull-out force from being applied stably and evenly to the anchoring structure. This unstable stress state directly leads to deviations in the test data, making it difficult to accurately reflect the true value of the insulation board's anchoring force. This poses a potential threat to the safety performance assessment of building exterior wall insulation systems and fails to meet the actual needs of accurate testing. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a device for testing the anchoring force of building exterior wall insulation boards. When the adsorption and stabilization component of this utility model is working, pressing the piston can expel the gas in the suction cup. The spring reset drives the piston to move, creating a negative pressure inside the suction cup, which can stably fix the mounting base on the insulation board, avoiding displacement or loosening of the device during the pull-out test, and ensuring that the pull-out force can be stably applied to the rivet or steel bar to be tested, thereby effectively improving the accuracy of the anchoring force test data.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a device for detecting the anchoring force of building exterior wall insulation board, including a mounting base, a clamping component, a nut and a pulling machine hydraulic cylinder. The pulling machine hydraulic cylinder is installed on the side of the mounting base, the clamping component slides inside the pulling machine hydraulic cylinder, and the nut is threadedly connected to the clamping component. It also includes an adsorption and stabilization component, which is used to adsorb and fix the insulation board, and assists in detecting the anchoring force of the insulation board.

[0006] More preferably, the clamping assembly is used to perform pull-out tests on the rivets or riveted reinforcing bars on the insulation board.

[0007] More preferably, the nut is used to secure the clamping assembly and the position of the nut can be adjusted to regulate the advance and deflection of the hydraulic cylinder of the drawing machine.

[0008] More preferably, the adsorption stabilization component includes a fixing tube, a suction cup, a piston, a spring, and an air leakage notch. The symmetrically arranged fixing tubes are installed on the mounting base, and several suction cups are respectively connected to the ends of the corresponding fixing tubes. Each fixing tube has a piston that is slidably connected inside, and each piston is connected to the mounting base with a spring. The symmetrically arranged air leakage notch is opened on the mounting base near the washing plate.

[0009] More preferably, the piston component is made of a soft material.

[0010] More preferably, it also includes a lifting handle, which is symmetrically arranged and fixed to the mounting base.

[0011] Compared with the prior art, the advantages of this utility model are: when the adsorption stabilizing component of this utility model is working, pressing the piston can discharge the gas in the suction cup, and the spring reset drives the piston to move, so that a negative pressure is formed inside the suction cup, which can stably fix the mounting base on the insulation board, avoid the device from shifting or loosening during the pull-out test, and ensure that the pull-out force can be stably applied to the rivet or steel bar to be tested, thereby effectively improving the accuracy of the anchoring force test data.

[0012] The nut, threaded onto the clamping assembly, can further secure the clamping assembly and enhance its clamping stability with the rivet or rebar. On the other hand, it can adjust the infeed and outfeed of the hydraulic cylinder of the drawing machine. It can accurately set the initial working state of the hydraulic cylinder according to the actual specifications of the rivet or rebar to be tested and the testing requirements, so that the testing parameters meet the corresponding testing standards and improve the accuracy of the testing process.

[0013] After the test is completed, the air leakage notch on the mounting base near the suction cup can be used to quickly allow outside air to enter the suction cup to balance the air pressure, so that the adsorption force between the suction cup and the insulation board disappears. The device can be removed by pulling the handle without strong operation, without damaging the surface of the insulation board, ensuring that the insulation board can still maintain a good appearance after the test.

[0022] Example: As shown in the attached figure, a device for testing the anchoring force of building exterior wall insulation board includes a mounting base 1, a clamping assembly 2, a nut 3, and a pull-out hydraulic cylinder 4. The pull-out hydraulic cylinder 4 is mounted on the side of the mounting base 1. The clamping assembly 2 slides inside the pull-out hydraulic cylinder 4. The clamping assembly 2 is used to perform pull-out tests on rivets or riveted steel bars on the insulation board. When the pull-out hydraulic cylinder 4 is activated, it pushes the clamping assembly 2 to move away from the insulation board. The nut 3 is threadedly connected to the clamping assembly 2. The nut 3 is used to fix the clamping assembly 2 and can adjust the infeed / outfeed amount of the pull-out hydraulic cylinder 4 by adjusting the position of the nut 3. The device also includes an adsorption stabilizing assembly, which is used to adsorb and fix the insulation board, assisting in the detection of the anchoring force of the insulation board.

[0023] Both the clamping assembly 2 and the hydraulic cylinder 4 of the drawing machine are existing technologies, and their detailed working principles and internal structures will not be described in detail here.

[0024] In this embodiment, the adsorption stabilization component specifically includes a fixing tube 5, suction cups 6, pistons 7, springs 8, and air leakage notches 10. The symmetrically arranged fixing tubes 5 are mounted on the mounting base 1. Several suction cups 6 are respectively connected to the ends of corresponding fixing tubes 5. The suction cups 6 are used to adsorb the insulation board and fix it to the mounting base 1. Each fixing tube 5 has a piston 7 slidably connected inside. The end of the piston 7 is made of a soft material. Each piston 7 is connected to the mounting base 1 by a spring 8. The symmetrically arranged air leakage notches 10 are located on the mounting base 1 near the washing plate. Furthermore, it also includes a lifting handle 9, which is symmetrically arranged and fixed to the mounting base 1. The lifting handle facilitates the removal of the entire device.

[0025] Workers can lift the entire building exterior wall insulation board anchorage force testing device through the lifting handle 9 fixed to the mounting base 1. First, align the clamping component 2 with the protruding rivets or riveted steel bars on the insulation board, adjust the position of the clamping component 2 so that the clamping component 2 firmly clamps these rivets or riveted steel bars, and ensure that the force can be stably transmitted to the anchorage structure to be tested during the subsequent pull-out process, so as to avoid deviations in the test data due to insecure clamping.

[0026] Next, the mounting base 1 is placed on the clamping assembly 2, which has already clamped the rivets or reinforcing bars, so that the suction cup 6 in the adsorption and stabilization assembly on the mounting base 1 is in contact with the surface of the insulation board. Then, the piston 7 is pressed, and the piston 7 slides towards the insulation board inside the fixing tube 5. During this process, the gas in the suction cup 6 is gradually discharged, and at the same time, the piston 7 compresses the spring 8 connecting it to the mounting base 1, and the spring 8 stores elastic potential energy. When the pressing of the piston 7 is stopped, the spring 8 releases the elastic potential energy and pushes the piston 7 to slide in the opposite direction in the fixing tube 5, that is, to move away from the insulation board. At this time, the internal space of the suction cup 6 increases and the gas cannot be replenished in time, thus forming a negative pressure. Under the action of the negative pressure, the suction cup 6 is tightly adsorbed on the surface of the insulation board, thereby stably fixing the mounting base 1 to the insulation board and preventing the mounting base 1 from shifting or loosening during subsequent testing, thus providing a stable foundation for anchoring force testing.

[0027] Next, the hydraulic cylinder 4 of the drawing machine is installed on the side of the mounting base 1. During installation, it is necessary to ensure that the position of the hydraulic cylinder 4 of the drawing machine corresponds to that of the clamping component 2, so that the hydraulic cylinder 4 of the drawing machine can smoothly push the clamping component 2 after starting, and avoid the deviation of the drawing force direction due to the installation position deviation, which would affect the test results. Then, the nut 3 is threadedly connected to the clamping component 2. By rotating the nut 3, the clamping component 2 can be further fixed, which can enhance the clamping stability between the clamping component 2 and the rivet or rebar. On the other hand, the infeed and outfeed of the hydraulic cylinder 4 of the drawing machine can be controlled by adjusting the position of the nut 3. The initial working state of the hydraulic cylinder 4 of the drawing machine can be accurately set according to the specifications of the rivet or rebar to be tested and the actual testing requirements, so that the test parameters meet the corresponding test standards.

[0028] When the hydraulic cylinder 4 of the drawing machine is started, the hydraulic cylinder 4 will push the clamping assembly 2 to move away from the insulation board. The clamping assembly 2 will drive the clamped rivets or steel bars to move synchronously. At this time, the anchoring force between the rivets or steel bars and the insulation board can be detected by the output force of the hydraulic cylinder 4 of the drawing machine.

[0029] After the test is completed, the staff can use the air leakage notch 10 on the mounting base 1 near the suction cup 6 to allow outside air to enter the suction cup 6 and balance the air pressure inside and outside the suction cup 6. At this time, the spring 8 returns to its original state and pushes the piston 7 to reset in the fixed tube 5. The adsorption force between the suction cup 6 and the insulation board disappears. Then, the entire device can be easily removed from the insulation board by using the lifting handle 9. The operation is convenient and will not damage the surface of the insulation board, ensuring that the insulation board can still maintain a good appearance after the test.

[0030] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
