Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in figures 1-6, an underground arched roof formwork support system comprises a plurality of truss type arch main supports 1, steel templates 2 with back ribs are paved at the tops of the truss type arch main supports 1, support bent frames 7 are connected to the two sides of the truss type arch main supports 1, windlass 5 is installed at the tops of the support bent frames 7, holes are formed in the two sides of a winding arch of the truss type arch main supports 1, steel strands 3 are arranged in the holes in a penetrating mode, plastic sleeves 8 are sleeved outside the steel strands 3, the other ends of the steel strands 3 are connected with the windlass 5, the diameter of the holes of the winding arch of the truss type arch main supports 1 is 5mm larger than that of the steel strands 3, and the steel strands 3 can conveniently penetrate through the holes. The ground is fixed with a ground anchor 6, and the winch 5 is connected to the ground anchor 6 through a steel strand 3. The truss type arch main support 1 comprises an upper chord 11 and a lower chord 12, and a plurality of web members 13 are connected between the upper chord 11 and the lower chord 12. The steel strand 3 and the upper chord 11 are connected by a screw pier 4. The supporting bent 7 is composed of several vertical bars 71 and longitudinal horizontal bars 72.
