The angled plate 2 and the transverse rib 4 are provided with screw holes 5, and the bottom of the plastic plate 6 is provided with a screw groove matching the positions of the screw holes 5 on the angled plate 2 and the transverse rib 4, through which the countersunk screws penetrate The plastic plate 6 is connected with the steel frame 1 through the threaded hole 5 and embedded in the steel frame 1 .

The vertical ribs 3 and the transverse ribs 4 are made of channel steel, angle steel or "Z" shaped steel.

The plastic plate 6 is made of modified reinforced polypropylene composite plate.

There are multiple protrusions 8 and grooves 9 on the outer wall of the formwork unit, and the positions of the protrusions 8 and the grooves 9 on the outer wall of adjacent formwork units cooperate with each other.

The utility model has the following advantages:

1. The template frame is welded by frame steel, and the formed steel frame 1 is provided with reinforcing ribs made of channel steel, angle steel or "Z" shaped steel, because channel steel, angle steel and "Z" shaped steel are rolled Made of profile, good rigidity, high strength, small deformation during use, small adhesion between plastic plate and concrete, easy demoulding, smooth surface of poured concrete wall, high molding quality;

2. The plastic plate in the formwork is made of modified reinforced polypropylene composite plate, which is waterproof, moisture-proof and flame-retardant, with high strength, good safety and long service life;

3. The plastic formwork is installed on the corner plates or transverse ribs at the four corners of the steel frame through countersunk screws, and the combination is firm and reliable;

4. Hinges are installed on the side walls between the adjacent steel frames of each formwork unit, so that the formwork unit can be folded for easy transportation.

5. Every two adjacent formworks are combined into a formwork unit, and the outer walls of the adjacent formwork units are combined and connected through the mutually matched protrusions 8 and grooves 9, so as to ensure that the formwork can be kept straight when installed.
