Abstract

The invention discloses a plane rigid frame loading experiment device. One side of a lower cross beam is provided with a side beam; the side beam is provided with a horizontal loading device, which is simple and convenient; a side beam pull rod is installed between the side beam and the lower cross beam, so that the strength and rigidity of the side beam and the left section of the lower cross beam are increased; a horizontal loading force measuring and force displaying device consists of a crank handle, a chain wheel shaft, a chain wheel base, a chain wheel, a chain, a spiral jack, a length adjusting rod, a length adjusting rod base, a horizontal force measuring sensor, a sensor base and a force displaying instrument; the chain wheel base is fixed on the upper end of the side beam; a rigid frame and bearing component consists of a left vertical rod, a cross rod, a right vertical rod, a base cross, a pin shaft, an upper gasket, a lower gasket, a middle gasket, a roller shaft and gasket fixing bolts; the left vertical rod, the cross rod and the right vertical rod constitute a single-span or multi-span rigid frame structure; the rigid frame change, load change and the bearing form are relatively convenient; a lateral constraint component restricts the lateral movement of the rigid frame.

Description

technical field [0001] The invention relates to structural mechanics experimental equipment used in schools, in particular to a plane rigid frame experimental loading device suitable for teaching experiments of building structures used in civil engineering and construction engineering majors in engineering colleges and universities. Background technique [0002] At present, in the teaching of civil engineering and construction engineering majors in colleges and universities, in order to help students verify the theoretical knowledge of architectural structures they have learned, and to cultivate students' ability of actual measurement, comprehensive application and innovation, a planar rigid frame experiment is set up. project. In this experimental project, the problem of loading the tested rigid frame must first be solved. At present, temporary measures are mostly taken to solve the loading problem of the tested rigid frame, and experiments are also carried out on small co...
