Detailed description of the invention
As figures 2-6, one builds large-span concrete beam combined type Bailey bracket bearing bent frame, comprise combined type Bailey bracket beam 3, steel pipe framed bent 4, support system 5, at least two combined type Bailey bracket beam 3 two ends be parallel to each other are seated on the steel box-girder 52 of the support system 5 being fixed on the upright body of wall 1 of concrete that twice are parallel to each other respectively, combined type Bailey bracket beam 3 evenly, is vertically provided with many i iron bases 6 different in size, to be parallel to each other, i iron base 6 is erected with steel pipe framed bent 4.
Described support system 5 is made up of multiple load-bearing steel corbel 51 and steel box-girder 52, and load-bearing steel corbel 51 is fixedly connected with the many embedded anchor cones 53 that the upright body of wall 1 of concrete is arranged, and steel box-girder 52 is erected on the end face of load-bearing steel corbel 51.
Described combined type Bailey bracket beam 3 is be compound beam that is square or rectangle by the section that multiple Bailey bracket is vertically assembled.
Many described i iron bases 6 are fixedly connected on the upper chord at combined type Bailey bracket beam 3 top by many channel-section steel pressing plates 7 and bolt 8, and i iron base 6 is welded with many reinforcing bar suspension columns 9.
Described steel pipe framed bent 4 is combined by steel pipe post 41 and level connection joint steel pipe 42, is provided with oblique bridging 43, is provided with horizontal cross brace 44 between level connection joint steel pipe 42 between steel pipe post 41.
The top of described steel pipe framed bent 4 is provided with concrete beam mould board 21.
Making of the present invention and installation process as follows:
