Method and apparatus for steel structure metal profiled sheet roof suction performance field detection

Abstract

The present invention discloses an apparatus for steel structure metal profiled sheet roof suction performance field detection. The apparatus comprises a main distribution beam, a primary distribution beam, a secondary distribution beam, pressing brackets, a pulling bracket, a magnetic absorber, an adjustment screw, a jack, a sensor, a displacement gauge, a strain gauge and a digital camera, wherein the lower portions of both ends of the main distribution beam are connected with the two pressing brackets, the jack is shelved on the middle position of the main distribution beam, the secondary distribution beam is connected on the primary distribution beam, the lower end of the pulling bracket is connected with the magnetic absorber, the magnetic absorber is arranged on a metal profiled sheet, the displacement gauge is arranged on the metal profiled sheet, and the sensor and the displacement gauge are connected through a conducting wire and the strain gauge. The present invention further discloses a method for steel structure metal profiled sheet roof suction performance field detection. The method and the apparatus of the present invention are mainly used in steel structure metal profiled sheet roof construction quality inspection, and can be used for steel structure metal profiled sheet roof structure safety identification.

Description

technical field [0001] The invention relates to a detection method and a device for a steel structure metal profiled plate, in particular to a method and a device for on-site detection of the roof suction performance of a steel structure metal profiled plate. Background technique [0002] With the rapid development of my country's economic construction, steel structure building systems are widely used in industrial and civil buildings. Since the 1980s, the emerging steel structure metal profiled plate roof enclosure structure with many advantages such as modern aesthetics, short construction period, light weight, energy saving and environmental protection has been widely used in industrial and civil buildings. With the use of metal profiled plate roofs in steel structures in engineering construction, my country's engineering circles have insufficient knowledge reserves for metal profiled plate roof design, construction, and inspection, resulting in a relatively lagging behin...

AI Technical Summary

Problems solved by technology

Under the action of wind, the roof often bears a large negative pressure, that is, suction. If the design load such as the self-weight of the metal profiled plate roof is not enough to resist this suction, the roof will be lifted and cause damage.

However, in the construction quality inspection of metal profiled plate roofs for steel structures, there is no on-site inspection of the suction performance of metal profiled plate roofs that involves design and on-site metal profiled roof construction and installation quality inspections, and the suction performance of metal profiled plate roofs On-the-spot detection method and device do not have so far

[0004] In recent years, the metal roofs of many steel structure buildings all over the country have been partly or completely lifted due to poor design considerations, unreasonable or on-site construction and installation quality problems, causing major economic losses and certain safety hazards
