Description

Technical Field

[0001] The utility model relates to the technical field of load test equipment, and more specifically, to a load performance test device for an anti-seismic connecting component. Background Art

[0002] Building seismic supports and hangers are seismic support facilities used in drainage, heating, ventilation, and air conditioning, electrical, gas, and fire protection systems. They are non-structural components that are primarily loaded by seismic forces and provide a secure connection to the building structure. They primarily consist of anchors, reinforcement hangers, seismic connection members, and seismic braces. Seismic connection members are used individually or in combination to connect seismic braces.

[0003] According to the requirements of the "General Technical Requirements for Seismic Supports and Hangers for Buildings" (GB / T 37267-2018) and the "General Technical Requirements for Seismic Supports and Hangers for Mechanical and Electrical Equipment in Buildings" (CJ / T 476-2015), seismic connection components must be tested for their load resistance. This means that seismic connection components should not experience significant deformation or damage under a certain load. The specifications specify that the direction of the test load for seismic connection components should be based on the angle of use. The "Code for Seismic Design of Building Mechanical and Electrical Engineering" (GB 50981-2014) stipulates that the vertical angle of the diagonal braces for lateral and longitudinal seismic supports and hangers should be 45° and not less than 30°. Accordingly, the direction of the test load for seismic connection components is also the same. In actual work, due to the complex and changing actual on-site environment, the design angles of the diagonal braces for seismic supports and hangers vary. However, the test angle of existing detection devices is difficult to adjust, and is often only targeted at common angles such as 30°, 45°, and 60°, which is obviously difficult to meet the actual detection work; for this reason, we propose a new load performance test device for seismic connection components.

[0020] In this embodiment, if Figure 1-2 As shown, the clamping assembly 2 is mainly composed of a clamping frame 21, a connecting rod 22, an adjusting sleeve 23, and two clamping blocks 24, wherein the clamping frame 21 is a U-shaped clamping frame 21; when working, it is used to drive the adjusting sleeve 23 to move upward on the upper seat of the clamping frame 21 by rotating the adjusting handle 26, and then push the two clamping blocks 24 on both sides of the installation groove to move upward along the inclined surface synchronously, thereby realizing the clamping and fixing operation of the seismic connecting component to be tested; the structure is stable and easy to install.
