Static loading device and method for anti-slip test of inclined supporting joint

Abstract

The invention discloses a static loading device and method for an anti-slip test of an inclined supporting joint. A ground beam is horizontally and fixedly arranged on a test bed, counterforce beams are arranged on the upper part of the ground beam in parallel, and a first side column and a second side column are arranged between the counterforce beams and the ground beam in parallel; the upper end of the first side column is hinged to one end of the counterforce beams, the lower end of the second side column is fixedly connected with the other end of the ground beam, a pressure gauge is arranged between the second side column and a jack, and the upper end of the jack tightly abuts against the other end of the counterforce beams; the lower part of an inclined supporting joint test piece isconnected with the ground beam, and the upper part of the inclined supporting joint test piece is hinged to the counterforce beams; a hinged rotation center between the inclined supporting joint testpiece and the counterforce beams, a hinged rotation center between the first side column and the counterforce beams and the top surface position of the jack are arranged in line. The static loading device is low in manufacturing cost, high in reliability, simple to install, capable of achieving self-balance, simple in operation method in the static loading process, and low in test condition requirement.

Description

technical field [0001] The invention belongs to the technical field of load test loading, in particular to a static loading device and a loading method for an anti-slip test of a diagonal support node. Background technique [0002] As a key part of the prefabricated steel structure building, the node plays a key role in the installation and use stage of the prefabricated building. With the continuous updating of prefabricated steel structure building forms, the connection forms of nodes are also constantly enriched and developed. However, the existing loading devices for testing the mechanical properties of nodes show certain limitations, such as the high price of servo loading devices, complex functions, and difficult operation. The shortcomings of cumbersome, bulky, inconvenient installation, and inability to automatically balance make the node test subject to various restrictions.

With the continuous updating of prefabricated steel structure building forms, the connection forms of nodes are also constantly enriched and developed. However, the existing loading devices for testing the mechanical properties of nodes show certain limitations, such as the high price of servo loading devices, complex functions, and difficult operation. The disadvantages of cumbersome, large size, inconvenient installation and inability to automatically balance make the node test subject to various restrictions
