Product Definition
Triangular Truss Single Side Wall Formwork refers to a complete forming system consisting of steel form panels and triangular truss supports.
Different from conventional double-sided wall formwork, this system only installs steel formwork and triangular truss supports on one side of the wall. The opposite side relies on retaining piles, original soil or permanent enclosure structures to resist concrete lateral pressure, requiring no double-side working space. It is a customized tool-type steel formwork specially designed for basement exterior walls and narrow adjacent walls.
Main Product Materials
| Main triangular truss | Q235B standard channel steel & punched angle steel, fully factory welded for strong bending resistance and anti-deformation performance. |
| Wall steel form panel | 3mm cold-rolled steel plate with 8# channel steel frame, integrally stamped for flat surface. |
| Adjustable base, pressure beam and embedded anchors | High-strength hot-rolled steel with high-load J-type anchor bolts. |
| Anti-corrosion surface treatment | High-temperature electrostatic plastic spraying / epoxy paint, rust-proof for outdoor construction and long-distance sea transportation. |
| Matching accessories | Hook lock parts, horizontal connecting steel pipes, safety guardrails, all standardized steel components. |
Competitive Advantages
Triangular Truss Single Side Wall Formwork 5 Core Competitive advantages
Excellent Waterproof Performance, Zero Leakage Risk
This rod-free formwork design creates intact concrete walls without tie rod holes, eliminating secondary hole sealing and waterproof treatment. It ensures superior water tightness for basements, metro and civil air defense projects and effectively reduces long-term leakage maintenance costs.
01
Stable Structural Performance, No Deformation
The self-balanced triangular truss with base embedded anchors reliably resists concrete lateral pressure and uplift force. It enables one-time pouring for 3–7.5m high walls without bulging, shifting or dislocation, delivering higher stability than traditional steel pipe bracing systems.
02
High Construction Efficiency, Labor and Cost Saving
Modular prefabricated steel units support integral tower crane lifting and fast bolt assembly. Full scaffolding and on-site timber processing are no longer required. It cuts assembly labor by 60%, shortens project schedules and reserves more on-site working space.
03
High Reusability, Low Overall Operation Cost
Full steel structure features high rigidity and anti-deformation performance, achieving over 50 construction cycles, much longer than traditional wood formwork. Durable anti-corrosion coating ensures easy cleaning and low maintenance, bringing excellent ROI for contractors and formwork rental enterprises.
04
Flexible Assembly & Customized Availability
Standard truss modules are freely splicable for wall heights of 3m–7.5m. The truss spacing is adjustable within 750–900mm according to actual pressure demands. Custom sizes and hot-dip galvanized finishes are available to fit various complex construction conditions.
05
Standard Construction Process
Triangular Truss Single Side Wall Formwork
Base Embedding: Pre-bury J-type anchor bolts and embedded steel plates during foundation slab pouring, matching the standard 800mm truss layout spacing.
Wall Line Setting & Leveling: Mark wall control lines, level the base with mortar and install sponge water-stop strips to prevent slurry leakage at the bottom.
Steel Bar Binding & Positioning: Install wall steel bars and thickness positioning bars; add water-stop rings to tie bars for waterproof exterior walls.
Integral Truss Lifting: Lift the complete unit of steel formwork + triangular truss by tower crane, lock the base with embedded anchor bolts.
Calibration & Reinforcement: Adjust verticality via base screw jacks; connect multiple trusses with horizontal steel pipes as an integrated whole, and install top locking bars to prevent outward expansion of the wall top.
Layered Concrete Pouring Control: Pour concrete in layers with each layer ≤500mm, control feeding speed and assign dedicated staff to monitor frame deformation in real time.
Form Stripping, Cleaning & Reuse: Remove anchor bolts and lift off the whole formwork once concrete reaches 50% design strength; clean concrete residues and apply release agent for cyclic use.
Core Application Scenarios
Basement and Civil Air Defense Exterior Walls
Foundation pit outer sides are equipped with retaining piles or underground continuous walls without external working space for double-sided formwork. Classified as standard building steel formwork with optimal waterproof performance.
Metro, Light Rail and Tunnel Lining Retaining Walls
Tall single-side concrete walls with high concrete lateral pressure, where simple steel pipe bracing fails to meet stability requirements.
Sewage Tank Walls and River Revetment Retaining Walls
Long-term water-contact structures with zero bolt holes to reduce water leakage risks.
Narrow Post-cast Strips, Long Corridor Side Walls & High-speed Railway Platform Single-side Walls
Limited site space requiring minimal occupation by support systems.
Special Reminder for High-risk Construction: Projects with wall height ≥4m require a special construction plan; customized extended truss segments are available for walls over 8m, with supporting technical documents for expert demonstration.

FAQ
Q1: Can Triangular Truss Single Side Wall Formwork be categorized as building steel formwork?
A: The complete set with steel panels and triangular trusses belongs to the building steel formwork category. If only triangular truss supports are purchased separately, they are classified as formwork support accessories.
Q2: Does this system have to match your factory's steel form panels?
A: It is compatible with standard steel frame wood formwork, aluminum formwork and full steel formwork from mainstream brands; truss supports can be sold separately.
Q3: How does the system resist concrete lateral pressure without wall tie rods?
A: The self-balanced triangular truss structure together with base embedded anchor bolts forms an anti-overturning force bearing system. Lateral pressure is transferred to foundation embedded components without through-wall tie rods.
Q4: How to handle rust prevention for sea freight transportation?
A: Extra thick anti-corrosion paint is applied before delivery; all steel components are wrapped with anti-rust film and fixed on wooden pallets to adapt to humid long-distance ocean shipping.
Q5: Do you accept small trial orders?
A: Trial orders starting from 20 truss sets are supported. Tiered discounts are available for long-term bulk purchases, together with complete supporting technical documents.
