Beijing-professional production of rubber expansion joints Yangqu County highway bridge expansion joints supplier factory

Beijing-professional production of rubber expansion joints Yangqu County highway bridge expansion joints supplier factory 18,230,181,118 joints means to prevent the building component temperature due to climate change (heat up, shrink), so that the structure cracks or damage along A construction site of houses in the longitudinal direction of the appropriate set of vertical slits. Bridge deck expansion joints to meet the requirements of the deformation, usually between two end of the beam, or set the position articulated joints on the bridge between the end of the beam and abutment. Expansion joints Type 1, galvanized sheet steel joints. This is an easy on joints, currently fabricated in small span girders bridge, when beam deformation often chosen within 20-40mm. 2, steel expansion joints. Steel expansion joints made of steel production, it can be directly subjected to vehicle load and size of the amount under the flexibility to adjust the thickness of steel plate, steel expansion joints are also appropriate for the bridge of the trial. Its structure is more complex, only on a larger temperature difference between regions or large span bridge was adopted. When the span is large, on the one hand to thick steel plate, and the need to adopt more sophisticated comb plate joints. 3, rubber expansion joints. It is a rubber band as a cross stitch material. This expansion joint structure is simple, easy to use, the effect is. A large amount of deformation in the larger span bridge, you can use a combination of rubber and steel joints. The company specializes in the production of two-component polysulfide sealant, rubber water stop, rubber seal, water swelling rubber seal, closed-cell polyethylene foam, inflatable mandrel, rubber bearings, expansion joints, two-component polyurethane sealants.
