Loading device for static load test of steel structure frame body

Abstract

The invention discloses a loading device for a static load test of a steel structure frame body, and the device comprises force sensors located exactly under the steel structure frame body, and a loading mechanism installed on the steel structure frame body. The device is characterized in that the loading mechanism comprises a loading beam, a distribution beam, hydraulic jacks, active steel pull rods, limiting steel pull rods, a counter-force pedestal, a steel base plate, and a steel sleeve; the loading beam and the distribution beam are connected and fastened at an intersection node through a bolt, thereby enabling the upper part of the loading mechanism to form an integrated body; the loading beam is connected with the counter-force pedestal located at the lower part through four active steel pull rods located at four corners of the loading beam and four limiting steel pull rods located at the central part of the loading beam; a part, at which the loading beam is located, of each active steel pull rod is provided with one hydraulic jack; and the force sensors are respectively disposed under vertical columns at four corners of the steel structure frame body. The device can achieve the loading of a load, can accurately measure the actual loading force of each vertical column, is reliable in force bearing, is simple, is convenient to operate, and is safety in loading.

Description

technical field [0001] The invention belongs to the technical field of load test loading, and in particular relates to a loading device for a static load test of a steel structure frame. Background technique [0002] At present, in the experimental research in the field of civil engineering, many static loading tests are required. For vertical loading of the steel structure frame, the common loading method is to use hanging heavy objects or stacking heavy objects to realize the steel structure frame. However, when the added load is large, it is easy to cause the steel structure frame to become unstable, prone to danger, the risk factor is high, the loading accumulation time is long and the workload is heavy. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art. The present invention provides a static load test loading device for a steel structure frame. The loading device composed of force bearings is used for loading vert...
