L-Shaped Wall Installation Process | Light Steel Formwork

Step 1: Site Preparation

Clean the foundation surface, ensure it is flat and level. Mark the exact L-shaped wall position according to the construction drawing.

Step 2: Place L-Shaped Corner Connector

Set the light steel corner angle at the right-angle turning position of the wall. Align it accurately with the marked line to ensure perfect 90° vertical angle.

Step 3: Install Wall Panels & Fix with Pins

Place the light steel formwork panels on both sides of the corner.
Align the panel holes with the holes on the corner connector.
Insert steel pins through the reserved holes to lock the panels and corner part tightly.

Step 4: Complete L-Shape Assembly

Repeat the pin-fixing method for all connection points.
The two-direction wall panels are firmly connected into a standard 90-degree L-shaped wall formwork system.

Step 5: Vertical Check & Reinforcement

Check verticality with a level tool.
All pin connections are double-checked to ensure no loose points before concrete pouring.

Step 6: Concrete Pouring & Formwork Stripping

Pour concrete evenly.
After concrete hardening (24–36 hours for wall), remove all pins and disassemble the light steel formwork for repeated use.

Zhuniu Plastic Formwork Integrated Construction Process for Beam & Slab

Zhuniu plastic concrete formwork supports one-piece integrated construction for floorslab and beam structures.

First, by handles use external corner connectors to splice the plastic panels to form the exact beam size and shape according to the construction drawing.

After the beam frame is fully shaped, use internal corner connectors to seamlessly connect the beam formwork with the floor slab formwork.

This integrated beam-and-slab connection method requires no cutting, no plywood splicing, greatly speeds up on-site assembly, ensures perfect structural integrity, and produces smoother concrete finished surfaces.

Super Easy Plastic Formwork Installation! Zhuniu plastic formwork measures 1500mm × 500mm and weighs only 10.25kg. One person can carry and install it easily, saving tons of time and labor on construction sites.
No heavy tools, no complicated steps! 3 simple installation steps for perfect concrete forming👇
Step 1: Splice Formwork to Required Size
Connect formwork panels with dedicated handles. Splice and adjust the panels to match your project’s required size for a neat, tight frame.
Step 2: Install Plastic Sleeves & Through-Wall Rods
Install plastic sleeves on the spliced formwork toprecisely control concrete thickness. Then thread through-wall rods through the sleeves to fix the formwork in place.
Step 3: Reinforce & Tighten
Reinforce the outer side with square steel pipes to resist concrete pressure and avoid deformation. Finally, tighten the nuts firmly. Done!
Why Choose Zhuniu plastic Formwork?
✅ Lightweight: 13.6kg/m², single-person operation
✅ Fast installation: 3 simple steps, high efficiency
✅ High accuracy: Consistent concrete thickness
✅ Stable & durable: Anti-deformation with steel pipe reinforcement
Ideal for all kinds of concrete construction projects! Upgrade your building formwork now.

This video shows the standard construction method for ditch concrete pouring using Zhuniu lightweight plastic formwork and beam clamps, simple, fast and high precision for channel and drainage ditch projects.

Step 1: Assemble and adjust the formwork height

First, assemble the plastic formwork panels according to the designed ditch depth. Adjust and fix the formwork height to ensure the overall flatness, verticality and dimension accuracy of the ditch formwork. Complete the whole ditch formwork enclosure as required before the next procedure.

Step 2: Install middle partition boards

Install fixed partition boards in the middle of the assembled formwork. The partition plates effectively support the formwork, prevent bulging and deformation during concrete pouring, and guarantee consistent internal width and regular ditch shape.

Step 3: Reinforce with two types of beam clamps

After formwork assembly and partition installation, use special beam clamps for overall reinforcement. We provide two optional fixing structures for different construction habits:

1. Screw-type beam clamp
Fixed by tightening bolts with an electric wrench. It features firm locking, adjustable tightness, reusable performance and strong overall stability, suitable for high-standard engineering projects.

2. Pin-type quick beam clamp
Fixed by inserting safety pins directly without tools. This type is ultra-fast to install and dismantle, greatly saves construction time and improves on-site working efficiency.

Both beam clamps perfectly cooperate with plastic formwork systems, effectively resist concrete lateral pressure, ensure no deformation, no leakage, and produce smooth finished ditch walls.
Noted: beam clamps usually used ditch height ＜600mm;
