Description

Technical Field

[0001] This utility model relates to the field of testing technology for the peel strength of roll joints, specifically a test device for peel strength of waterproof roll joints. Background Technology

[0002] Waterproof membrane is a widely used waterproofing material in construction projects. It is usually composed of polymer-modified asphalt and other materials. The peel strength and impermeability of the joints of the waterproof membrane are among the indicators for judging its quality. Before conducting the joint peel strength test, representative samples of the waterproof membrane layer should be selected. The samples should be undamaged and uncontaminated, and their dimensions should meet the test requirements. To ensure the accuracy of the test results, it is recommended to randomly select samples from different batches and different locations of the membrane.

[0003] The user cuts the selected waterproof membrane sample to the specified dimensions, ensuring the seams are flat and free of air bubbles. The sample is then fixed to the testing machine using clamps, ensuring the clamps are aligned and the clamping force is moderate to prevent slippage or damage during testing. The peel speed and peel length of the testing machine are set according to relevant standards, and the test begins. During the test, the peeling condition at the seams should be closely observed, and relevant data recorded. However, with the diversification of building structures, the angles of areas requiring waterproof membranes vary, causing the joints of the waterproof membrane to be in a twisted state. Currently, waterproof membrane joint peel strength testing equipment only tests the peel strength of two pieces of waterproof membrane at a vertical angle and 180 degrees. A device is needed that can test the peel strength of waterproof membrane joints in a twisted state. Utility Model Content

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The user cuts the selected roll waterproofing sample to the specified dimensions, ensuring the seams are smooth and free of air bubbles. Then, using clamps, secure the sample to the testing machine, ensuring the clamps are aligned and the clamping force is appropriate to prevent slippage or damage during testing. Set the peel speed and peel length of the testing machine according to relevant standards and begin the test. During the test, closely observe the peeling at the seams and record the relevant data.

[0030] In related technologies, with the diversification of building structures, the parts requiring waterproof membranes also exhibit diverse angles, causing the joints of the waterproof membranes to be in a twisted state. Currently, the peel strength testing equipment for waterproof membrane joints only tests the peel strength of two pieces of waterproof membrane at vertical angles and 180 degrees. There is a need for a device that can test the peel strength of waterproof membrane joints in a twisted state.

[0031] To address some of the problems in related technologies, this application provides a waterproof membrane seam peeling test device. When a seam peeling test under torsion is required, the user fixes both ends of the sample and turns on motor 211. A transmission wheel is fixedly mounted on the output end of motor 211 via a rotating shaft. Simultaneously, a disc 22 is rotatably mounted on L-shaped rod 21. A transmission wheel is mounted on the rotating shaft connecting disc 22 and L-shaped rod 21. The two transmission wheels are connected by a transmission belt. Therefore, motor 211 can control the disc 22 to rotate, causing L-shaped rod 21 to rotate. One end of the sample fixed on L-shaped rod 21 rotates while the other end of the sample is fixed, thus the entire sample is torsion. The user then controls L-shaped rod 21 to rise to perform the waterproof membrane seam peeling test under torsion.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-4This application provides a waterproof membrane seam peel test device, including an adjustment device 1; the adjustment device 1 includes: a housing 12 disposed on the top of a control console 11, a motor 13 disposed on the top of the housing 12, the output end of the motor 13 passing through the housing 12 and fixedly connected to a screw 14, a slider 15 threaded on the screw 14, the slider 15 being slidably connected to the housing 12; the adjustment device 1 is provided with a torsion device 2, the torsion device 2 including: an L-shaped rod 21 disposed on the slider 15, a motor 211 disposed on the L-shaped rod 21, the... An L-shaped rod 213 is provided on the housing 12; a disc 22 is rotatably mounted on the L-shaped rod 21 and the L-shaped rod 213; a transmission belt 212 is mounted on the transmission wheel connected to the output end of the motor 211 and the transmission wheel connected to the rotating shaft of the disc 22; a box 23 is mounted on the disc 22 and the L-shaped rod 213; a screw 231 is provided through the box 23; a slider 232 is threaded onto the screw 231, and the slider 232 and the box 23 are slidably connected; a clamping arm 235 is mounted on the slider 232; and a clamping arm 236 is mounted on the box 23.

[0034] When conducting a seam peel test on waterproof membrane, the user first cuts the selected waterproof membrane sample to the specified dimensions, ensuring the seam is flat and free of air bubbles. Then, the user controls the output of motor 13 to rotate clockwise via the wireless transmitter on control panel 11, causing screw 14 to rotate synchronously. The clockwise rotation of screw 14 lowers slider 15, which in turn lowers L-shaped rod 21. The user controls the descent height of L-shaped rod 21 according to the length of the membrane sample, ensuring the distance between L-shaped rod 21 and L-shaped rod 213 meets the length requirements of the membrane sample. The user then controls the rotation of screw 231 via knob 234 on box 23, causing slider 232 to move horizontally and move clamping arm 235. One end of the sample is placed between clamping arm 235 and clamping arm 236 on L-shaped rod 21. Knob 234 is then continuously rotated to reduce the distance between clamping arms 235 and 236 until one end of the sample is clamped. The other end of the sample is clamped by clamping arms 235 and 236 on L-shaped rod 213. The user then rotates the two nuts 233 clockwise. The screw 231 moves horizontally until it abuts against the box 23, restricting the rotation of the screw 231 and fixing the positions of clamping arms 235 and 236, thus securing both ends of the sample. The user then controls motor 13 to rotate counterclockwise, controlling slider 15 to drive L-shaped rod 21 upward to pull the sample. As the distance between L-shaped rod 21 and L-shaped rod 213 changes, the sample is peeled off. The user can record the test data. When a torsional seam peeling test is required, after securing both ends of the sample, the user turns on motor 211. The output end of motor 211 is fixed with a transmission wheel via a rotating shaft. At the same time, a disc 22 is rotatably mounted on L-shaped rod 21. The disc 22 and the rotating shaft rotatably connected to L-shaped rod 21 are equipped with transmission wheels. The two transmission wheels are connected by a transmission belt. Therefore, motor 211 can control the disc 22 to rotate, causing L-shaped rod 21 to rotate. One end of the sample fixed on L-shaped rod 21 rotates, while the other end of the sample is fixed. Thus, the entire sample is twisted. The user then controls L-shaped rod 21 to rise to conduct a peel test of the waterproof membrane seam under torsion.

[0035] In some embodiments, the bottom of the L-shaped rod 21 is symmetrically provided with sliders 24, which are slidably connected to the housing 12. Providing sliders 24 improves the stability and smoothness of the L-shaped rod 21 during movement.

[0036] In some embodiments, a knob 234 is provided at one end of the screw 231, which passes through the housing 23. The knob 234 provides a point of force and space for the user to control the rotation of the screw 231, thereby improving the accuracy of the user's control over the rotation of the screw 231.

[0037] In some embodiments, a nut 233 is threaded onto the second screw 231. When the user rotates the nut 233 clockwise, the nut 233 moves horizontally on the second screw 231 until it abuts against the housing 23, restricting the rotation of the second screw 231 and fixing the positions of the first clamping arm 235 and the second clamping arm 236.

[0038] In some embodiments, rubber pads are provided on the first clamping arm 235 and the second clamping arm 236. The rubber pads are soft and have a good coefficient of friction, which can improve the stability when clamping samples.

[0039] In some embodiments, the L-shaped rod 21 and the L-shaped rod 213 are of the same size. The identical size of the two L-shaped rods ensures that the sample is perpendicular to the horizontal plane when fixed, thus guaranteeing the accuracy of the test data.

[0040] In some embodiments, the slide groove on the housing 12 is provided with a dustproof strip. The dustproof strip consists of two automatically closing rubber strips. The dustproof strip opens when the slider slides and automatically closes after sliding to prevent excessive dust from entering the interior of the housing 12 and making it difficult to clean.

[0041] In some embodiments, signal transmitters are provided on the console 11 and the motor 13. After the remote control signal is decoded, a specific control signal is generated. This signal is processed by the circuit and ultimately switches the state of the power supply circuit through components such as relays or solid-state relays, thereby controlling the opening and closing of the power switch of the motor 13.
