[0107] The pressing part 424 includes:

[0108] The pressing plate 4241 is arranged on the outer side of the mounting plate 421.

[0110] Finally, the pouring frame 1 is further provided with an automatic material distributing machine for pouring concrete into the steel mold 2 and a vibrating rod for vibrating after the pouring of the material distributing machine.

[0111] Working principle: ​

[0112] Step one: through the lifting equipment to hoist the steel column body 8 to the pouring frame 1 front and rear two ends on the erection groove 72 of the alignment block 71;

[0113] Step two: the lower two groups of steel columns in the four groups of steel molds 2 move to the middle under the action of the two lateral moving assemblies, thereby fitting the lower half of the steel column body 8, and the positions of the two ends of the steel column are calibrated by the calibration assembly 7 during the movement of the two lateral moving assemblies and clamped;

[0114] Step three: the sealing unit 4 in the former group seals the gap between the two adjacent steel molds 2 located at the lower end of the steel column body 8 and the connecting plate 3 passing through the through groove 21, and the sealing unit 4 in the latter group seals the gap between the steel column body 8 and the steel mold 2, wherein the steel column body 8 at the latter sealing unit 4 is directly provided with two half-rectangular frame type sealing rubber pads 41 due to the simple shape of the connecting plate 3 at this position, and the sealing is installed manually;

[0115] Step four: the first pouring is performed by the automatic material distribution machine, and the first pouring height is the lowest horizontal height of the through groove 21 of the adaptive connecting plate 3 at the lower end, and the first vibration is performed by the vibrating plate. The purpose of this is to prevent one-time pouring. Due to the high pouring position and the rectangular ring shape of the pouring body, the bubbles in the lower concrete are not easy to discharge. If the vibration force is too large, the concrete is easy to flow out from the gap of the sealing rubber pad 41, although it has been sealed;

[0116] Step five: the two groups of steel column bodies 8 at the upper end are clamped by the connecting plate 3 of the two groups of steel columns at the lower end of the upper end steel mold moving assembly 6 and the steel column body 8, and then the connecting gap is sealed by the two sealing units 4 on the two sides of the former group, and the gap at the front and rear ends is sealed by the two half-rectangular ring-shaped sealing rubber pads 41. Then a pouring opening is left above the two groups of steel column bodies 8 at the upper end, and the second pouring is performed from the pouring opening by the automatic material distribution machine, and the second vibration is performed. The pouring opening can be provided in multiple and large openings to facilitate pouring and bubble discharge. The pouring opening can also be provided in a full opening type as shown in the figure to facilitate pouring; Figure 1

[0117] It should be noted that before calibration, release agent needs to be applied to the inner wall of the steel mold 2 to facilitate separation of the steel mold 2 and the poured concrete after solidification.
