(1) firstly, placing a wallboard on a bearing plate platform to enable the horizontal center point of the wallboard to be coincident with the center position of the bearing plate platform;
(2) opening the data processing device, rotating a down-turning nut on the sliding connecting rod, and enabling the whole detection platform to move downwards to a position which is 10mm less than the thickness of the wallboard from the platform of the bearing plate by observing a scale on the sliding connecting rod;
(3) and recording the reading of each extensometer to obtain the flatness of the plate surface.
The utility model has the advantages that: the utility model discloses easy and simple to handle, swift, measurement accuracy is high, and measuring area is big, can completely detect the roughness of taking notes monoblock panel each point, realizes that the surface roughness of many sizes building wallboard detects.
