The supporting upright posts 1 are oppositely arranged in pairs, and one side template 3 along the linear direction is arranged at intervals of 50 cm. The bottom end of the supporting upright post 1 is provided with a pointed end 13 so as to be embedded into the hard soil body 7, and horizontal lateral displacement caused by the formwork supporting and pulling stabilizing device in the pouring process of the concrete 10 can be effectively avoided.

Two ends of the supporting flat rod 2 are respectively inserted into the corresponding socket notches 12. The support flat bar 2 is used for supporting the support upright post 1.

The side templates 3 are respectively arranged on the left side and the right side and are in a linear structure and used for maintaining the shape of the solidified concrete. The sideforms 3 are each confined between two opposing support uprights by square timber. The square wood keeps consistent with the linear structure trend. And reinforcing steel bars 9 are arranged between the side formworks, and as shown in fig. 5, the reinforcing steel bars 9 comprise main bars 91 and stirrups 92.

The split bolt 4 penetrates through a hole 14 reserved in the middle of the support upright post 1. The purpose of adjusting the tightness of the supporting upright post 1 can be realized by adjusting the split bolt 4. The split bolt 4 is a hexagon bolt with the specification and model number of M10, the nominal diameter is 9.78mm, two ends of the split bolt are provided with screw threads, and the length of the screw thread sleeve thread at each end is 150mm.

Referring to fig. 1 and 2, the square timber 5 includes an upper square timber 51 and a lower square timber 52, and is fixed to the upper and lower ends of the outer surface of the installed side formwork 3 by iron nails 6, and keeps the same direction with the side formwork 3. The square timber 5 can rapidly and evenly transmit the pulling force of the split bolt 4 acting on the supporting upright post 1 to the side template 3, so that the surface of the side template 3 is evenly stressed. In the process of pouring the concrete 10, because the side formworks 3 are subjected to the extrusion action of the lateral pressure of the concrete 10 in the horizontal direction, the side formworks 3 act on the supporting upright 1 through the square timbers 5 and maintain stress balance with the horizontal reaction force acting on the supporting upright 1.

As shown in fig. 2, the joints of the square timber 5 and the supporting columns are further provided with upper layer auxiliary square timber 53 and lower layer auxiliary square timber 54. The side edges of the auxiliary square timbers are respectively tightly attached to the outer side surfaces of the side templates, the upper layer square timbers or the lower layer square timbers and the supporting stand columns.

The cushion block 8 is a square body, a downward concave U-shaped groove 81 is formed in the upper surface of the cushion block 8, and the depth of the groove 81 is not more than one third of the thickness of the cushion block. The cushion block 8 is fixed on the stirrup 92 through the iron wire 82, so that the position of the steel bar 9 can be fixed, and the side template 3 is supported. And the supporting force generated by the supporting flat rod 2 and the cushion block 8 and the pulling force generated by the split bolt 4 for adjusting the tightness of the supporting upright post 1 maintain the stress balance, so that the device obtains a stable state, and further maintains the form of the concrete 10 after pouring.

In the embodiment, the length of the horizontal socket notch 12 is 50mm, the wall thickness is 3mm, and the outer dimension of the socket is 50mm × 50mm; the length of the vertical rectangular hollow aluminum alloy upright rod is 500mm, the wall thickness is 3mm, and the external dimension of the structure is 50mm multiplied by 30mm.
