Detailed ways

As shown in Figure 1, it is a schematic diagram of the overall structure of a turnable triangular support frame used for the support system of the shallow round warehouse overhanging board, including a cross bar 1, a vertical bar 2, a diagonal strut 3, a connecting reinforcement 4, The vertical pole positioning base 5, the bolts 6 and the embedded parts 7, the cross bar 1, the vertical pole 2 and the diagonal strut 3 are connected by the connecting reinforcement 4 and the bolt 6 to form a triangular support frame. The upper end of the horizontal bar 1 is welded with a vertical support. The rod positioning base 5 is used to support and position the upper end structure. The inner side of the vertical rod 2 is welded with an embedded part 7, which is used to connect and fix with the concrete of the shallow round warehouse. The structure of the embedded part 7 is vertical steel welding. Two sleeves, the spacing of the sleeves is 500mm.
