Description

Technical Field

[0001] This utility model relates to the field of building technology testing, specifically to a pull-out test device for a snap-fit ​​type upright lock plate support. Background Technology

[0002] Currently, in the exterior decoration of large venues, exhibition halls, and other public buildings, roofs often use standing seam metal profiled sheets. These sheets are typically connected to their supports using interlocking or rolled-edge seam connections. With technological advancements and product updates, a type of interlocking standing seam sheet has become increasingly popular in engineering practice due to its larger interlocking area, stronger interlocking ability, and better waterproofing. However, the actual stress mechanism of this connection type of support remains unclear, lacking systematic theoretical results, making it impossible to roughly estimate its load-bearing capacity theoretically. Existing pull-out tests for various specimens are generally conducted using universal testing machines, but these machines lack suitable testing equipment for rolled-edge standing seam supports, rendering such tests impossible. Only overall wind uplift tests can be performed, but these are too costly and labor-intensive, making repeated testing unsuitable. Therefore, providing a direct testing method for the actual load-bearing capacity of interlocking standing seam sheet supports is crucial. Utility Model Content

[0003] This invention provides a snap-fit ​​type upright lock plate support pull-out test device. This device can effectively test the pull-out bearing capacity of the support, providing reliable design data for actual engineering. It has a simple structure and is easy to operate.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clamping type upright locking plate support pull-out test device, including a clamping member, with connecting members on both sides of the clamping member to cooperate with it, and a pull rod that cooperates with the test piece is detachably provided at the lower part between the connecting members.

[0005] Furthermore, the clamping component is T-shaped, comprising a horizontal section and a vertical section. Protruding mounting blocks are provided on both sides of the vertical section. The upper part of the connector has slots that mate with the mounting blocks, and the mounting blocks are equipped with detachable limiting rods. The horizontal section is used for clamping the upper chuck of the tensile testing machine. After the mounting blocks are inserted into the slots of the connectors on both sides, limiting rods are installed on the outer sides to achieve the installation of the clamping component and the connector.

[0006] Furthermore, the mounting block is provided with a limiting hole that is adapted to the limiting rod. The limiting hole is located in the middle of the mounting block, and the limiting rod is inserted into the limiting hole to realize the connection between the connector and the clamping member.

[0007] Furthermore, the distance between the two limiting holes should be consistent with the distance between the installed connectors, so that after the limiting rod is inserted into the limiting hole, the connector and the clamping part are locked together.

[0008] Furthermore, the lower part of the connector has a mounting hole for mounting the pull rod, and a limit screw is provided at the outer end of the pull rod located on the connector. The limit screw is installed in the mounting hole to limit the pull rod.

[0009] Furthermore, the distance between the limit screws on both sides is equal to the distance between the outer sides of the two connecting pieces.

[0010] Furthermore, the pull rod is a round bar that adapts to and engages with the hook of the test piece, and the mounting hole is a horizontal round hole. The diameter of the round bar is consistent with the diameter of the test piece to facilitate fastening and installation.

[0011] In summary, the pull-out testing device for a clamp-type upright lock-edge plate support provided by this utility model can test the strength of the clamp-type upright lock-edge plate support. It is equipped with clamping components, connecting components, and tie rods for convenient installation. The test results closely match actual engineering conditions and accurately reflect the actual pull-out bearing capacity of the support. Furthermore, different connecting components and tie rods can be selected according to the size of the specimen to test clamp-type upright lock-edge plate supports of different sizes. In addition, due to the presence of the clamping components, the entire testing device can be used on testing machines of different tonnages without changing the hydraulic chucks of the testing machine, enabling rapid testing. It is simple to operate and convenient to use. Attached Figure Description
