Large displacement modular expansion/single-group expansion joint
High-displacement modular telescopic device
The large displacement modulus expansion device is the upgrading and upgrading of the market in the 1990s, and the domestic hot rolled profile steel and the sealing rubber band are assembled from the main materials. Its reasonable structure, long service life, convenient installation and maintenance, is superior to plate rubber expansion joint. The large displacement modular expansion device is divided into two forms: the single-group expansion joint and the multi-group expansion joint.
Single- group expansion joint
Requirements for installation site
The single-ancestor joint consists of section steel, anchor member and sealing rubber band, allowing the displacement to be 0-120 mm, and the main type is type GQF-C-40, 60, 80, type XF (SSFB)-80, type SD-80,100,120, single-group sewing is common. See the following figure for section steel and sealing strip for use.
