Tel: 13932863899 13323080510 Zhang Company website: www.hsshengri.com I Sheng date of the company, is located in Hengshui City, rubber base - Zhao Xin Economic Development Zone, covers an area of ??60,000 square meters, construction area of ??25,000 square meters, fixed assets of 80 million yuan, the annual output value of 200 million yuan, the product marketing. Our main products: pot bearings, rubber bearings, bridge expansion joints, rubber water stop, rubber dam, waterproof board, drainage board, geotextiles, geogrids, high-speed guardrail, tunnel fire retardant paint, and high-speed Fence other rubber products. Widely used in railway bridges, roads and bridges projects, tunnels and subway project; water conservancy, power generation and sewage treatment works. GQF-C-type bridge expansion joints, GQF-Z type, GQF-E type, GQF-F type, GQF-MZL type, all hot-rolled joints overall shape of the different type of steel designed to bridge expansion joint products. Which GQF-C type, GQF-Z type, GQF-L type, GQF-F type bridge expansion device for stretching the amount of 80mm below the bridge, GQF-MZL-type bridge expansion type is by the side beams, beams, beam Modular bridge expansion joint devices and interlocking institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges. joints [] refers to the expansion joint to accommodate expansion and contraction deformation material impact on the structure and in the structure Set gap. Also known as temperature seam joints, is a common term construction projects. Its main role is to prevent the housing cracks due to climate change. Its approach is: set aside a certain distance gaps, all disconnected from the building roof, walls, floors and other components above the ground at intervals along the longitudinal direction of the building, building the foundation for its buried by the temperature change is small, do not disconnected. Expansion joint width is generally 2 cm to 3 cm, inside seam fill insulation, two joints spacing structures are clearly defined in the specification. If the building plane size is too long, because the thermal expansion and contraction of the reason, may result in excessive temperature stress in the structure, the need to structure a certain length position with joints will be divided into several parts of the building, which is the temperature sewn seam. Different architecture, different distances between joints, our current standard "design of concrete structures" GB50010-2010 this special provisions.
