In the prior art, the ballast retaining walls and partition walls are usually cast by first casting the beam body, and then separately building brackets and vertical formwork to cast the ballast retaining walls and partition walls. This method is relatively complicated to operate. For example, the patent with application number 202222944589.3 discloses an integrated crash barrier prefabricated platform.

This structure requires the beam body to be cast and solidified before the ballast retaining wall or partition wall can be cast. It has gradually become unsuitable for modern fast-paced construction needs. Utility Model Content

In addition, the horizontal bracket 600 is two back-to-back opposite channel steels, which can be connected and fixed by connecting bolts or other structures. The adjusting screw 701 is installed in the two back-to-back opposite channel steels, and the upper and lower ends are clamped and fixed to the channel steels by mounting plates and nuts. By adjusting the horizontal position of the adjusting screw 701 on the channel steel, the horizontal position of the vertical wall formwork 200 can be adjusted.

[0044] In order to ensure the stability of the vertical wall formwork 200, a support rod (support rod group 800) is connected between two adjacent vertical wall formworks 200 or between the vertical wall formwork 200 and the front support leg 300 or the rear support leg 400. There is no need to drill holes in advance on the vertical wall formwork 200 to reserve tie rod installation holes, and there is no need to install tie rods, which reduces the construction steps; the setting method of the support rod ensures the stability of the vertical wall formwork. In the prior art, tie rods are generally used to connect the two end formworks or to connect by installing fixed mounting seats on the solidified beam body.

[0046] 1. Install the integral formwork of the beam body (beam body mold 500) and the vertical wall formwork 200, and fix the vertical wall formwork 200 to the integral formwork;

[0047] 2. Adjust the vertical wall template 200 to the specified position;

[0048] 3. The vertical wall formwork 200 is erected by using a support rod (support rod group 800) and the like;

[0049] 4. Cast the beam;

[0050] 5. Cast the partition wall directly without waiting for the beam to solidify;

[0051] 6. Demoulding.
