Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as Figure 1~3 As shown, a device for testing the mechanical properties of portal scaffold components includes a portal reaction frame 1 and a frame body 3 arranged inside and outside. The portal reaction frame 1 is composed of uprights 12 on both sides and main beams 11 spanning between the uprights 12 on both sides to form a door-shaped frame, and the frame body 3 is vertically placed in the door-shaped frame. For the convenience of adjusting the installation height of the crossbeam 11, there are multiple groups of bolt holes 121 longitudinally arranged on the column 12, and each group of bolt holes 121 is two arranged side by side. 3 to apply force, so as to transmit the force to the door frame 10 to be tested placed on the frame body 3 for detection. The frame body 3 includes side beams 33 and upper beams 31 and lower beams 3...

The invention discloses a gantry scaffolding component mechanical property detecting device, which comprises a gantry reaction frame and a frame body, wherein an actuator for applying force to the frame body is arranged on the gantry reaction frame; the frame body comprises longitudinal beams on two sides, an upper beam and a lower beam; the actuator is opposite to the top surface of the upper beam, and the upper beam can move up and down relative to the longitudinal beams; close to ends, the upper beam and the lower beam are respectively provided with a supporting base; a plurality of supporting positions in which supporting legs of a gantry to be detected are inserted are arranged on the supporting bases side by side, and a clamping platform for pressing an upper transverse rod of the gantry to be detected is detachably connected with the two supporting bases of the upper beam. The detecting device is additionally provided with a measuring tool for detecting deformation quantity of the gantry to be detected and a holding rack of the measuring tool. The invention discloses a detecting method using the device. The detecting device disclosed by the invention is capable of firmly and conveniently clamping the gantry to be detected, and is high in universality; the detecting method using the device is convenient, and the detecting result is accurate.
Description
technical field [0001] The invention relates to a detection device for construction equipment, in particular to a detection device and a detection method for the mechanical performance of portal scaffolding components. Background technique [0002] Portal scaffolding is composed of portal frame, cross support, connecting rod, hanging buckle scaffolding board or horizontal frame, lock wall, etc., and then set horizontal reinforcement rod, scissors brace, sweeping rod, sealing rod, bracket and base, And it adopts a standardized steel pipe scaffolding that connects the wall parts to the main structure of the building. It is the most commonly used scaffolding in the construction field. The gantry is the main component of the gantry scaffolding. Its force-bearing members are welded steel pipes, which are welded by vertical bars, cross bars and reinforcing bars, etc., and undertake most of the vertical pressure applied to the gantry scaffolding. Therefore, the door The mechanical...
