technical parameter
● The short span of indoor support and hoisting is generally 1.5-3m. The mid-span of outdoor columns is generally 6m.
● The support and hanger configuration of the non-straight section should follow the following principles: When the width of the bridge is less than 300mm, a support and hanger should be installed on the side of the straight section 300-600m away from the junction of the non-straight section and the straight line. When the width of the bridge is ≥ 300mm, in addition to the following conditions, a support and hanger should be added in the middle of the non-linear section.
● The center distance between the layers is 200, 250, 300, 350mm when the bridge is set in multiple layers.
● Expansion joints 20-30mm (metal bridge) should be reserved for the straight section of the bridge every 50m.
