Practical clamp for mechanical property test of anti-seismic suspension and support connecting component and use method of practical clamp

Abstract

The invention discloses a practical clamp for a mechanical property test of an anti-seismic suspension and support connecting component and a using method of the practical clamp. The practical clamp comprises a fixed connecting mechanism and a bearing mechanism, and the fixed connecting mechanism is mainly composed of a high-strength bolt, a matched nut and a reinforcing plate, is connected with an opening part of the bearing mechanism and bears shearing force generated in the stretching process. One end of the bearing mechanism is provided with cylindrical steel with certain strength and used for being connected with a universal chuck of a universal testing machine, the other end of the bearing mechanism is an opening part capable of containing the mechanical property test fixing end of the anti-seismic support and hanger connecting piece, and the opening part meets the bearing requirement needed by the mechanical property test of the anti-seismic suspension and support connecting piece. The using method of the practical clamp comprises the following steps that the two ends of the anti-seismic suspension and support connecting component are fixedly connected with the practical clamp bearing mechanism through the fixed connecting mechanism; the practical clamp and a chuck of the universal testing machine for testing are connected in a matched mode and clamped; and test parameters are set according to a metal material mechanical property test standard.

Description

Technical field: [0001] The patent of the present invention relates to the field of construction, and in particular to a practical fixture for testing the mechanical properties of connected components of an anti-seismic support and hanger and a method for using the same. Background technique: [0002] HVAC, water supply and drainage, power, technology, electrical and other pipes, equipment, cables, etc. in buildings must be fixed and installed with brackets. Most of these installations are in various complex environments. In order to cope with various complex environments, ensure long-term The service life of the anti-seismic support and hanger must be strictly controlled. The quality directly affects the difficulty and cost of management and maintenance in the later stage of the building. It is one of the effective means to solve the problem to carry out various inspections on the anti-seismic support and hanger according to the specific situation. 2018 In 2018, the state p...

Problems solved by technology

[0004] The purpose of the present invention is to provide a practical fixture for the mechanical performance test of the seismic support and hanger connection member in order to solve the above problems. Through the adjustment device and the telescopic rod, it can effectively solve the above-mentioned problem when it needs to be detected. When the car is driven on the dynamometer, for the accuracy of the detection, the car needs to be parked in the middle of the detection structure. This requires multiple startups to adjust the vehicle, which increases the complexity of the detection and reduces the efficiency. The size of the current dynamometer Make it fixed, which makes it impossible for the dynamometer to detect models of different sizes. Different models of cars require different dynamometers for testing, which increases the cost of testing and increases the technical problems of tedious testing.
