In order to solve the technical problem, the inner mold supporting structure for forming the cup-shaped foundation cup opening comprises a steel plate cylinder, a transverse reinforcing angle steel frame, a vertical reinforcing angle steel frame and an angle steel inner support, wherein the transverse reinforcing angle steel frame and the vertical reinforcing angle steel frame are welded and then arranged in the steel plate cylinder to form a stress frame of the steel plate cylinder, the transverse reinforcing angle steel frame and the vertical reinforcing angle steel frame are respectively welded with the inner wall of the steel plate cylinder, and the angle steel inner support is welded on the inner wall of the steel plate cylinder in a polygonal shape.
Further, the steel plate cylinder is a rectangular cylinder, and the area of a lower opening of the rectangular cylinder is smaller than that of an upper opening.
Further, horizontal reinforcement angle steel frame includes follows the horizontal angle steel of rectangle barrel direction of height interval welding in each inner wall of rectangle barrel, vertical reinforcement angle steel frame includes follows the vertical angle steel of rectangle barrel direction of height welding in the rectangle barrel inner wall four corners, the both ends of horizontal angle steel respectively with adjacent vertical angle steel welding.
Furthermore, the angle steel inner support is welded on the inner wall of the rectangular cylinder in a quadrilateral shape and is arranged at intervals along the height direction of the rectangular cylinder.
The internal mold supporting structure for forming the cup-shaped foundation cup opening comprises a steel plate cylinder, a transverse reinforcing angle steel frame, a vertical reinforcing angle steel frame and an angle steel internal support, wherein the transverse reinforcing angle steel frame and the vertical reinforcing angle steel frame are welded and then arranged in the steel plate cylinder to form a stress frame of the steel plate cylinder, the transverse reinforcing angle steel frame and the vertical reinforcing angle steel frame are respectively welded with the inner wall of the steel plate cylinder, and the angle steel internal support is welded on the inner wall of the steel plate cylinder in a polygonal shape. The structure overcomes the defect of the traditional cup-shaped foundation inner mold erection, avoids the deformation and expansion of the mold plate, improves the binding force of the interface of the lower bearing platform foundation and the new and old concrete of the upper cup-shaped foundation, and ensures the appearance quality of the cup-shaped foundation after the pouring is finished.

The invention is described in further detail below with reference to the following figures and embodiments:
FIG. 1 is a schematic plan view of an internal mold supporting structure for cup-shaped base cup rim molding according to the present invention;
fig. 2 is a schematic elevation view of the supporting structure.
Detailed Description
The embodiment of the invention is shown in fig. 1 and fig. 2, the internal mold supporting structure for forming the cup-shaped foundation cup mouth comprises a steel plate cylinder 1, a transverse reinforcing angle steel frame 2, a vertical reinforcing angle steel frame 3 and an angle steel internal support 4, the transverse reinforcing angle steel frame 2 and the vertical reinforcing angle steel frame 3 are welded and then arranged in the steel plate cylinder 1 to form a stress frame of the steel plate cylinder 1, the transverse reinforcing angle steel frame 2 and the vertical reinforcing angle steel frame 3 are respectively welded with the inner wall of the steel plate cylinder 1, and the angle steel internal support 4 is welded on the inner wall of the steel plate cylinder 1 in a polygonal shape.
Preferably, the steel plate cylinder 1 is a rectangular cylinder, and the area of the lower opening of the rectangular cylinder is smaller than that of the upper opening.
Preferably, the transverse reinforcement angle steel frame 2 comprises transverse angle steel 21 welded on each inner wall of the rectangular cylinder at intervals along the height direction of the rectangular cylinder, the vertical reinforcement angle steel frame 3 comprises vertical angle steel 31 welded on four corners of the inner wall of the rectangular cylinder along the height direction of the rectangular cylinder, and two ends of the transverse angle steel 21 are respectively welded with the adjacent vertical angle steel 31.
