Bridge expansion joint A Suzhou 40 bridge expansion joint manufacturer bridge expansion joint consists of a long rubber sealing strip, a group of steel side beams and anchors. The anchors on the outer side of the steel side beam are welded with the embedded steel bars at the end of the beam, and then connected with the beam body after pouring the transition section of high strength concrete. GQF-Z80 bridge expansion joint has the characteristics of reliable connection, smooth connection with bridge deck, sealed water stop, flexible expansion, smooth driving and long service life. It is suitable for bridges with 40 mm, 60 mm and 80 mm expansion. Main materials: steel side beam: rolled by 16Mn steel, the profile is Z-shaped. Sealant strip: Made of chloroprene or ethylene propylene diene rubber, it has good aging resistance and flexural resistance. Anchors: There are three kinds of anchors, anchor rings and anchor plate structures. Bridge engineers can choose according to the design thickness of bridge deck. Our company can also specially design and manufacture GQF-Z80 bridge expansion joints, ZD-80 expansion joints, Z expansion joints, Z80 expansion joints, which are of high quality and low price. Bridge expansion joint like rubber strip is the expansion deformation of bridge deck caused by high elasticity of rubber to adapt to temperature change. The rubber strip for bridge expansion joint has the advantages of convenient installation, smooth driving, waterproof, dust-proof, low noise, light weight and low cost, and has been welcomed and praised by bridge engineering circles. The product is anti-aging, processed from wear-resistant rubber, can withstand repeated loads of vehicles, long service life. It can be used for replacement of old bridges and selection of new bridges. Bridge expansion joint rubber strip is specially designed for various types of bridge expansion joint matching products, specifications and models are all in accordance with the Ministry of Communications, Ministry of Railways standard production can be matched with C, E and F joints and other types of expansion joints. The 40-type bridge expansion joint is a new bridge expansion device designed by Zhongjiao Highway Planning and Design Institute. The product is suitable for highway, urban bridge, viaduct and interchange projects in large traffic areas. The 40-type expansion joint consists of a whole rubber sealing strip, a set of rigid side beams and anchors. The inner side of the steel side beam is provided with a groove which can fix the rubber sealing strip. Anchors soldered on the outside of steel girders are welded with embedded steel bars at the end of the girders. After pouring high-strength concrete, the connection with the girder body is reliable. It has the characteristics of smooth connection with the bridge deck, water sealing, flexible expansion, smooth driving and long service life. It is suitable for bridges with 0-40 mm expansion.
