Application Scenarios of Formwork Support in Engineering Projects
Building Roof Slab and Floor Formwork
LVL timber is arranged below the formwork as secondary joists, evenly distributing the weight of the concrete. It is less prone to downward deflection and bending under stress, ensuring uniform thickness and a smooth, flat surface for the cast-in-place slab, reducing the need for subsequent grinding and repair work on the wall and top surfaces.
Shear Wall and Column Formwor
Vertically arranged as inner back joists for shear walls, square columns, and round columns, it provides stable rigidity and prevents lateral bending. When used with steel pipes and square steel for reinforcement, the timber deformation under concrete lateral pressure is minimal, effectively controlling formwork expansion and displacement, resulting in vertical and flat walls after pouring.
Basements and Garages
Underground garages, civil defense projects, and basement roof slabs bear heavy loads and have high pouring thicknesses, requiring stringent bending and load-bearing capacity of the joists. High-density LVL timber has stable overall strength and low bending attenuation in wet concrete environments, making it suitable for load-bearing joists in high-formwork areas.
Bridges, Culverts, and Water Conservancy Projects
For outdoor construction projects such as municipal roads, bridges, culverts, canals, and river embankments, exposed to wind and sun, LVL timber has a lower probability of cracking compared to ordinary solid wood. Its batch performance is consistent, facilitating material acceptance and standardized on-site layout for construction teams.
Core Performance Advantages
Made from select high-quality poplar veneer, high-pressure and high-temperature integrated molding, resulting in uniform density and a grain-fed load-bearing structure. Specifically designed for repeated use on construction sites:
High Bending Strength
All veneers are arranged with the grain, ensuring load distribution along the wood grain direction. This results in significantly higher bending strength than mixed timber of the same specifications, less deflection under the same span, and reduced bending during concrete pouring, effectively guaranteeing formwork accuracy.
No Large Knots
LVL is made by gluing and pressing veneers layer by layer, avoiding natural defects such as large knots, hollow centers, and diagonal grain that are common in solid wood. The entire timber has balanced strength, preventing breakage at localized weak points.
Precise and Uniform Dimensional Tolerances
Width and thickness errors are strictly controlled. Timber from the same batch is uniform in size and height, ensuring even spacing of the formwork on site. No need for on-site selection or planing, significantly improving formwork erection speed.
High Turnover Rate
The structure is stable and, during repeated demolding and re-molding cycles, it is less prone to end cracking, splitting, or bending. It can be reused multiple times, reducing the frequency of timber procurement and replenishment on construction sites, resulting in lower overall material costs for long-term projects.
Production Process and Specialized Workmanship for Engineered Timber
Focusing on four key indicators-high bending strength, minimal cracking, dimensional stability, and suitability for on-site turnover-a complete set of construction-grade production control procedures is implemented:
1. **Premium Veneer Selection:** Veneers are carefully selected from the main trunk sections, eliminating those with rot, wormholes, large areas of discoloration, or cracks. This ensures stable veneer properties from the source, laying a solid foundation for high-strength finished timber.
2. **Segmented Precision Drying for Even Moisture Content Control:** Veneers are dried in segments in a continuous drying kiln, maintaining a moisture content within the suitable range for construction materials. This ensures uniform drying throughout the veneer, preventing excessive internal stress and end cracking in the finished product.
3. **Uniform Grain-Oriented Stacking:** All veneers are stacked with the fiber direction aligned, ensuring the highest possible bending strength along the grain. This is the core technological difference between LVL (Laminated Veneer Wood) construction timber and plywood.
4. **Uniform Application of High-Strength Structural Adhesive:** Waterproof, construction-grade adhesive is used. The adhesive layer is highly resilient and has excellent water resistance. It prevents delamination and separation between layers in humid environments such as concrete curing, meeting the requirements of damp construction sites.
5. High-Tonnel Constant Temperature and High Pressure Hot Pressing: High-pressure compaction of the veneer removes excess air between layers, ensuring a tight bond and improving overall density and bending rigidity. This prevents separation of layers under stress.
6. Long-Term Constant Temperature Curing to Release Internal Stress: After hot pressing, the rough timber is placed in a constant temperature curing room for a sufficient duration to slowly release the internal stress generated during hot pressing, preventing spontaneous bending and deformation of the finished timber.
7. Precise Sanding on Four Sides, Standard Cutting, and End Waxing Protection: Sanding on four sides ensures precise width and thickness dimensions; cutting to the required length for the construction site; applying wax to both ends of the timber to lock in internal moisture, reducing rapid moisture loss during outdoor storage and lowering the probability of end splitting.
## Mechanical Testing and Project Acceptance Qualification
We offer comprehensive sampling and testing services for the mechanical properties of building materials, and can provide the necessary supporting documentation for project acceptance:
1. **Passing Sampling Inspections of Bending Strength and Modulus of Elasticity** Bending strength and modulus of elasticity tests are conducted on each batch of products. Mechanical indicators are stable, and test reports can be used for on-site high-formwork special scheme verification and project acceptance materials.
2. **Compliant Testing of Adhesion Strength and Water Resistance** Water-resistant adhesive tests are conducted to verify the water resistance of the adhesive, ensuring that the layers do not delaminate under humid conditions during concrete curing.
3. **Production Batch Quality Certificate, Traceable Batch Number** Each batch of products comes with a production certificate, and the production batch number is traceable, facilitating on-site material acceptance and inspection by supervisors and clients.
4. **IPPC Fumigation Treatment for Export Orders, with Supporting Customs Clearance Documents** For overseas infrastructure projects, IPPC fumigation stamps can be provided, along with fumigation certificates, certificates of origin, and other complete customs clearance documents to meet overseas customs inspection requirements.
