Parameter:

The Lattice girder welding machines produce standard lattice girders, thrust girders and wall girders.

Lattice girder applications: Often used in permanent precast concrete formwork to in-situ slabs, lattice girders provide rigidity to the unit and acts as a mechanical fixing between the precast formwork and the in-situ concrete.

Characteristic:

1. Layout plan: Line wire pay-off → Line wire straightening unit → rod bending unit → welding system → cutting system → truss girder collector

2. Only need one operator to control, it has been widely applied in the area of high speed railway and building structure, etc.

3. Controlled by servo motor and PLC, which can promise the machine work stable and high accuracy.

4. It is full auto collected and produced, no need many workers, and it is high efficiency.

5. Apply famous brand elements and parts, can service for long time and work stable.

Truss or Lattice girders are known as cubical reinforcing elements and are used for the production of prefab slabs, joist slabs and double walls in various forms.

Lattice girder applications: Often used in permanent precast concrete formwork to in-situ slabs, lattice girders provide rigidity to the unit and acts as a mechanical fixing between the precast formwork and the in-situ concrete.

Lattice girder floors or half-slabs comprise a thin reinforced precast concrete slab with cast in lattice girders and which are provided with an in-situ concrete topping. This most frequently used reinforced floor type is used for all applications in residential and commercial construction. The fundamental benefits are amongst other things a high-quality product at a reasonable price, extreme dimensioning versatility and rapid on installation.

Zig-zag wire	Hot rolled steel HPB235, cold rolled steel 550, 650grade

Application of Triangular lattice girders

Truss girder applied in high-speed railway double block track sleeper: in order to adapt to the development ofChina's high-speed railway demands, our country has introduced the RHEDA2000 double block without frantic jumble rail technology. Radar 2000 type without frantic jumble structure system applies embedded track connected by truss girder, double block type sleeper installed according to the regular distance, each group of sleeper has two truss girders to support, pouring concrete after the sleepers installed in correct location, and the track sleeper connects to the loading layer of the track.
