In the construction industry, the choice and quality of materials used in forming systems are crucial for ensuring structural integrity and durability. This article will delve into the precise material requirements for wood formwork, outlining specific guidelines and standards essential for effective construction practices.

1. Base Formwork Requirements

The base formwork constitutes the foundational support for concrete structures. For optimal performance, it is recommended that the base templates be constructed from high-quality softwood boards. Acceptable materials include pine boards, poplar boards, and eucalyptus boards, ensuring the thickness of the side panels is precisely 20mm.

2. Main Beam Bottom Formwork Specifications

The primary focus of the formwork system relies heavily on the main beam’s bottom template. This structural element should be crafted from softwood boards as well, with a minimum thickness of 40mm. In contrast, the column formwork and floor templates are preferred to be made from engineered wood formwork, specifically utilizing nine-layer plywood with a thickness of 12mm.

3. Support System Configuration

When it comes to the supporting system, it is essential to utilize cedar logs, recognized for their strength and reliability. The smaller diameter of the logs used should not be less than 70mm, ensuring sufficient support for the formwork. Additionally, the connection system must employ small square timber measuring 400x500mm. It is crucial to note that for the lower support system, steel pipe supports are mandatory.

4. Quality Considerations for Wood Materials

The integrity of the formwork system largely depends on the quality of wood selected. It is vital to avoid using wood that exhibits brittleness, severe warping, or moisture-induced deformation. Such defects can compromise the structural performance and lead to costly repairs or delays. Thus, ensuring all wood used in the formwork system is free from such flaws is paramount in achieving a successful overall construction plan.
