 Tai'an City, Shandong steel joints GQF Hao-Hao-Oda offer customized 18812089123 2243337241 Phone 0318-2276600 QQ online QQ mailbox 2243337241@qq.com expansion joint construction features: the entire length of a rubber seal, a group of just qualitative edge beams and anchor components. The inside edge of steel beams can be fixed with a rubber seal groove. Solid welded steel beams at anchor outside, with embedded steel beam ends are welded, high-strength concrete pouring after the transition, with the beam connecting reliable, smooth engagement with the deck, sealing sealing, stretching flexible, smooth traffic, use long life characteristics. For stretching the amount of 0 ~ 80mm bridge. Installation and construction of roads and bridges bridge expansion joints is a very important building construction projects, installation quality directly affects the smooth ride and comfort, quality of service and the age of large bridges. RB modular multi-directional displacement bridge expansion is insufficient for our traditional style and comb modulus telescopic device exists, especially in the bridge, cable-stayed bridge bridge vertical, horizontal, multi-directional deflection torsion Function Deployment extensive research and practice, in a "safe, comfortable, economical, durable, easy," the purpose, successfully developed a new generation of bridge expansion devices, the technology in the international advanced level. Bridge expansion joints creep and shrinkage of concrete, reinforced concrete bridges and prestressed concrete bridge to consider its creep and shrinkage. Xu Liang variable by elastic deformation under the pre-stress creep coefficient multiplied ￠ = 2 is obtained. The amount of shrinkage in the temperature dropped to 20 ℃ conversion. Should consider when installing concrete creep and shrinkage of the completed part, for all the creep and shrinkage should be multiplied by the reduction factor, age creep is calculated time after prestressing, shrinkage is pouring After the concrete to be installed at all age calculation, prestressed after setting the telescopic device subject to applied. Bridge deflection caused by a variety of load, live load, dead load and other end of the bridge will take place angle change, leaving the telescopic device generates a vertical, horizontal and angular displacement. If the beam is relatively high, and accompanied by vibration of the case, should pay particular attention. RB modular multi-directional displacement bridge expansion no springs or elastic stretchable structure, there is no gap modulus concept, so there is no stretch of the beam is blocked or uneven gaps and other issues. Cross stitch plate means the end of the beam covering the whole gap, damping rubber plate is not directly pressed, telescopic devices and stainless steel slide close to seamless, not intrusion of impurities, garbage comb between the comb is sloping force launched and driving away, do not enter the beam end gaps. Sealing device from spam abuse, rainwater infiltration underside of the guide device structure sparse water flow, excellent water resistance, not easy to aging, damaged. Fall, our lungs is often more partial prosperous, then we must be less spicy food such as: garlic, leeks, onions, ginger, pepper, etc. then we have to eat some acidic foods, such as: apple, pomegranate, mango, hawthorn, grapefruit, water chestnuts and so on. More spur of the moment. In the fall comes, the weather, the temperature sometimes quite hot, so sometimes it can be some stuffy, so a lot of people will often eat summer fruit. Then in fall morning, we must To drink some porridge, porridge can make us fall porridge Spleen Stomach generally: Pear rice porridge, rice porridge hawthorn, almond rice porridge, rice porridge persimmon, white radish rice porridge.
