Description

Technical Field

[0001] The utility model relates to the technical field of wallboard detection equipment, in particular to a wallboard impact resistance test device. Background Art

[0002] Building wall panels are a main component commonly used in prefabricated buildings. There are building wall panels of various materials. Therefore, in order to improve the safety and quality of buildings, it is necessary to use an impact test detection device to intuitively detect the impact resistance of building wall panels. However, when it is necessary to measure concrete wall panels of different specifications, the required impact force is different. The operator is often required to remove the sandbag, replace the hanging rope with a suitable length according to the needs, install the sandbag on the hanging rope, and then install the hanging rope and sandbag on the support frame. After changing the length of the hanging rope, if the specifications of the wall panels used each time are different, the operator needs to repeat this operation each time, which increases the cumbersomeness of using the wall panel impact test device in this process; in addition, the existing building wall panel impact test device is not convenient for efficient clamping and positioning of various types of building wall panels. When conducting an impact test, the building wall panels are prone to offset or shaking, which affects the accuracy of the test results.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a wall panel impact test device [CN02113199.6], which includes a support frame, a first clamping rod, a second clamping rod and a sandbag, the support frame is vertically arranged, the first clamping rod and the second clamping rod are arranged in parallel, the support frame is fixedly provided with a hanging rope, one end of the hanging rope is fixedly connected to the sandbag, the top of the support frame is fixedly provided with a sliding rod, the length direction of the sliding rod is perpendicular to the length direction of the support frame, the hanging rope abuts against the sliding rod, and pulleys are arranged at both ends of the sliding rod, the pulley abuts against the hanging rope, and the support frame is provided with a storage assembly for storing the hanging rope, and the length of the hanging rope is adjusted according to the demand through the cooperation of the storage assembly, so that the distance between the sandbag and the ground is changed, thereby changing the impact force when the sandbag is straightened to the same height, which is convenient for operators to complete the experiment according to the demand, and improves the convenience of using the wall panel impact test device.

[0004] The above scheme solves the problem of cumbersome use of wall panel impact resistance testing equipment in the prior art to a certain extent, but the scheme still has many shortcomings, such as: it is not convenient to efficiently clamp and position various types of building wall panels, and the building wall panels are prone to displacement or shaking during impact resistance tests, which affects the accuracy of the test results.
