Description

Roof truss load test detection platform Technical Field The utility model relates to the technical field of building structure detection, in particular to a roof truss load test detection platform. Background With the rapid development of the building industry, modular buildings are gradually increased, wherein roof trusses are taken as important components of building structures, the bearing capacity and the safety of the roof trusses are directly related to the overall stability of the building, at present, the detection technology of the roof truss structures mainly comprises static load tests, dynamic load tests, nondestructive detection and other methods, in the detection process, the roof trusses are vertically placed on bottom support columns and lifting columns through cranes, two sides of the roof trusses are kept in a vertical state by the support columns, firstly, concrete slabs are weighed by weighing plates firstly through a tower crane, then the deflection value of the tower crane when the concrete slabs are lifted and placed on the roof trusses is changed, and deflection measuring instruments respectively measure the load performance at two ends and the middle part of the bottom of the roof trusses.
