Ikhtisar proyek

Client	China Communications No.2 Engineering Bureau
Location	Pingzan Expressway Branch 8
Scope	Bekisting balok T & substruktur custom — pasokan eksklusif
Material	Baja Q235B canai panas, panel 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.

Untuk Tol Pingzan seksi 8, Zhongbian merancang dan membangun bekisting baja custom khusus untuk balok T dan komponen substruktur, disuplai ke Biro Teknik Transportasi Tiongkok No.2.

Custom berarti dirancang mundur dari gambar balok: tata letak panel, geometri flens, dan mekanisme pelepasan disesuaikan dengan siklus pengecoran yard, bukan diadaptasi dari katalog.

Bekisting membawa standar pembuatan pabrik — panel Q235B 3–5 mm, sambungan las penuh, toleransi ±0.5 mm, dan perakitan uji sebelum pengiriman.

Pertanyaan yang sering diajukan 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.
