Product Description

Boyoun U girder has undergone gradual improvement and development to create Boyoun's unique product system. The U-girder formwork system can be opened and closed as a whole, and the overall hoisting is 50% higher than the traditional process. The design is straightforward and can be created in one go.

With the rapid development of urban rail transit projects, the U-Beam is widely used on viaduct roads. Currently, U girder is one of the most innovative viaducts used in urban rail transportation. It has the advantages of noise reduction, low building height, high space utilization, and good appearance. With the advancement of technology, construction methods have changed from cast-in-place to precast hoisting. Use either double crane lifting or gantry crane lifting to hoist the U girder.

Our key projects

Boyoun is a professional enterprise that designs and manufactures U-Beam formworks. The U-Beam has been successfully applied to Shanghai Urban Rail Transit, Qingdao Intercity Rail, Pakistan Light Rail, Dubai Light Rail, etc.

Specification

Precast U girder formwork structure: outer side formwork, inner formwork, bottom formwork, support lead screw, jack, work platform, Vibrator, crawling ladder, blanking plate, etc.

Advantages

1. The inner formwork is fixed by the cross beam and the external formwork. The upper part uses jackscrews to adjust and fix the position of the inner formwork. The inner formwork is retracted and supported as a whole through hydraulic cylinders. It has a high degree of automation, shortens the construction period, and improves construction efficiency.

2. The outer formwork is connected to the hinge axis on the ground. Through the shoulder top and the support screw device, the outer formwork can be opened and closed as a whole. The operation is simple and greatly protects the U-beam from being scratched when lifting it.

3. Rubber strips are used to seal the outer formwork, inner formwork, and bottom formwork to prevent any leaks of slurry.

4. The vibrators are arranged crosswise inside and outside to enhance the compactness and appearance quality of the concrete.

FAQ

Q1. What is the load-bearing capacity of precast U-beams?

Answer: The load-bearing capacity of precast U-beams is influenced by factors such as their size, production materials, and processes. Boyoun precast U-beams can withstand large weights and have good bending and shear resistance after precise calculations and testing.

Q2.What is the applicable span range for precast U beams?

Answer: The applicable span range of precast U-beams depends on actual needs and design requirements, but it is usually suitable for bridges and other structures with small to medium spans. The applicable span range needs to be evaluated and designed based on the actual situation.
