Lanzhou Zhongchuan International Airport Transportation Hub Project

By simply adjusting the relative position of the connector during connection, the track lines of the upper and lower threads of the butted reinforcement can be adjusted from non collinear to collinear

The strength of double screw sleeve is up to grade I, and the joint can be connected in the same plane. The reinforcement cage connection does not need to be staggered by 50%

Wulongxing double screw sleeve has the advantages of high strength, simple operation, fast construction speed and good mechanical properties

It has the characteristics of convenient, fast and simple connection, no power saving in construction, no obstruction in rain or wind, and all-weather construction
