Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the utility model and not to limit the scope of the utility model.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, the large-span light space steel truss comprises a truss 1 and a support frame 2;
the support frame 2 comprises a support column 22, a reinforcing cross beam 26, a top connecting seat 21 and a base 24;
the top of each support column 22 is connected with a top connecting seat 21, a reinforcing cross beam 26 is arranged between every two adjacent support columns 22, a base 24 is arranged at the bottom of each support column 22, and the bases 24 are fixed through foundation bolts 23;
the truss 1 is in a hollow structure;
the support frame 2 is connected with the truss 1 through a top connecting seat 21.
Further, the support frame 2 is a triangular support frame.
