The invention relates to a field pull-out testing device for a metal roof board, comprising a pull rod, a measuring and connecting device, a gantry support and an operating table, wherein the operating table parallel to the tested metal roof board is paved on the tested metal roof board; the gantry support is fixed in the middle of the operating table; one end of the pull rod penetrates through the gantry support, and the other end of the pull rod is connected with the tested metal roof board via the measuring and connecting device; and the pull rod moves upwards to realize pull-out of the tested metal roof board. The field pull-out testing device disclosed by the invention is used for detecting the connection and fixation conditions of buckled compressive metal plates and engaged compressive metal plates, and preventing the phenomenon that the metal roof board is blown away by wind due to insufficient connection strengths of the parts; and the experimental device can be used for conveniently performing field pull-out detection, and verifying whether the connection strengths of the key components of the metal roof board achieve design requirements.
Description
technical field [0001] The invention relates to an on-site pull-out test device for a metal roof panel, in particular to an on-site test device for the pull-out resistance of a snap-fit type and an occlusion-type press-type metal roof panel. Background technique [0002] At present, metal profiled plates are widely used in building enclosure systems, especially snap-fit and occlusal type profiled metal plates. After these metal plates are installed, it is difficult to determine their connection and fixing conditions, especially for wind resistance Performance, because the construction technology and quality are not in place, the connection between these metal plates and the fixed bracket and the connection between the fixed bracket and other connections are prone to quality problems. In recent years, many metal roofs have been blown away by the wind, which is caused by these quality problems. Therefore, the development of this experimental device can facilitate on-site p...
