Experiment device applicable to spatial penetrated joints

Abstract

The invention discloses an experiment device applicable to spatial penetrated joints. The experiment device comprises two mutually vertical gantries, wherein the two gantries respectively are a gantry consist of main gantry box-shaped columns with lug plates and main gantry box-shaped cross beams, and a gantry consist of secondary gantry box-shaped columns with lug plates and secondary gantry cross beams, the tops and the bottoms of the two gantries are symmetrically provided with ring beams, the inner sides of the box-shaped columns with the lug plates of the two gantries are provided with box-shaped ring beams capable of vertically moving in the vertical direction of the box-shaped beams, the bottoms of the two gantries are provided with two mutually vertical main ground beams and secondary ground beams, inclined connecting beams are respectively arranged between the two mutually vertical adjacent ground beams, and upper flanges of the main ground beams, the secondary ground beams and the inclined connecting beams are respectively provided with equidistant screw bolt holes used for connecting experiment test element bases. The dismountable experiment device has the advantages that the transportation is convenient, high space adaptability is realized, and the experiment device can be used for the loading of any space angle.

Description

technical field [0001] The invention relates to a test device, in particular to a space intersecting node test device, which is suitable for static tests of arbitrary space intersecting nodes. Background technique [0002] With the sustained and rapid development of my country's national economy, large-span space steel structures have been more and more widely used in engineering. The space tube truss system is widely used in long-span steel structure engineering. The space tube truss is a space truss structure formed by intersecting steel pipes and steel pipes. Therefore, the node is the force transmission hub of the space tube truss, its structure is complex, there are many intersecting members, the welds are staggered, and the force is complicated. In order to ensure the safety of the structure, it is generally necessary to conduct experimental research on the joints of space tube trusses. [0003] The general practice is to manufacture a special test device for a spec...

Problems solved by technology

[0003] The general practice is to manufacture a special test device for a specific space node. This type of test device is often disposable or temporary, lacks versatility, and causes a lot of waste

Or simplify the space tube truss nodes into plane nodes, and then use a relatively simple gantry device to conduct experimental research on the simplified plane nodes, but the research on the plane nodes obtained by the simplified process can only reflect the original nodes to a certain extent. Practical mechanical properties, with great limitations
