Location	Pingzan Expressway Branch 8
Scope	定制 T 梁与下部结构模板 —— 独家供货
Material	Q235B 热轧钢板，面板 3–5 mm

Custom T-beam moulds supplied for the Pingzan Expressway branch. A T-beam is long and narrow, so straightness over the full length — not the panel thickness — is what decides whether the finished beam is acceptable.

针对平赞高速 8 标段，中编专为中交二公局设计并制作 T 梁与下部结构构件的定制钢模板，独家供货。

定制意味着从梁体图纸反向设计：面板排布、翼缘几何与脱模机构都按预制场的浇筑节奏来定，而不是从现成目录里改。

模具沿用工厂标准制造质量 —— Q235B 面板 3–5 mm、背筋全长满焊、尺寸公差 ±0.5 mm，发货前完成试拼。

常见问题 questions

What is the hardest part of building a T-beam mould?

Straightness over length. A T-beam section is long and narrow, so any bow in the panel shows as a visible line along the finished beam. The panels are jig-assembled and the casting face is checked against a straight edge rather than relying on the steel supplier tolerance.

Why specify steel rather than timber for T-beam work?

Repeat geometry and tolerance. A bridge contract casts the same T-beam section many times, and holding plus or minus 3 mm internal dimensions plus a consistent surface finish is difficult in timber beyond the first few casts.

What tolerance should I ask for on T-beam moulds?

Plus or minus 3 mm on internal dimensions is standard and is what most bridge specifications require. Squareness matters as much as side lengths, so specify diagonal tolerance as well — typically 4 mm across the section.
