Special-shaped steel expansion joint replacement and installation/comb-shaped steel plate expansion joint manufacturer quotation
Company landline
Hengshui Guangrun Engineering Rubber Co., Ltd. specializes in the production of special-shaped steel expansion joints and provides you with new special-shaped steel expansion joints Quotation, special-shaped steel expansion joint construction plan, etc., call the manufacturer for direct supply, wide range of products
Special-shaped steel expansion joints are placed and welded using a crane or manually to place the expansion joint device into the slot, please note The left and right front and rear positions must be accurate. If there is interference with the embedded steel bars, you can bend them appropriately, and then use an aluminum alloy ruler and feeler gauge to adjust the height of the top surface of the expansion joint device from the middle to both ends until the top surface is lower than the asphalt road surface. At this time, if the expansion joint device The gap width just meets the installation temperature requirements, and the embedded steel bars can be pulled to the anchor ring of the expansion joint device nearby for welding. The sequence is to spot weld from the middle to both ends, then check and retest. When the requirements are met, repair welding from the middle to both ends. To ensure firm welding, there should be at least two welds per meter on each side, and the length of each weld should not be less than 100 mm. After the welding is completed, the fixed door frame can be cut off in time. If the gap width of the expansion joint device does not meet the installation temperature requirements, you can use the above method to first weld and fix a side beam and the embedded steel bars, then gradually cut off the fixed door frame from the middle to both ends, adjust the gap and height before welding .
After all the special-shaped steel expansion joints and bridge expansion joints are assembled according to the design requirements, they will be transported to the construction site by the manufacturer or user. If its length exceeds the allowable limit for transportation or cannot be transported as a whole due to other reasons, it can be transported by splitting. . After the bridge expansion joints arrive at the construction site, they should be stored as close to the installation location as possible and placed on supports at least higher than the ground. , the same excellent bridge expansion joints, different installation quality, use effect and durability will be significantly different.
The code designation of special-shaped steel expansion joints indicates that the code designation method of bridge expansion joints is consistent with the transportation industry standard expression method of the People's Republic of China. Taking the , , , and type bridge expansion joints as examples, among them are the bridge expansion joint devices stipulated in the transportation industry standards. Code, type code straight beam connecting rod chain type (,,,,) indicates the shape of the special-shaped steel, and the number indicates the displacement of the telescopic device. and etc. indicate the type of rubber, indicate natural rubber, indicate chloroprene, and indicate EPDM rubber
Special-shaped steel expansion joint transportation and packaging The expansion joint device should be packaged in a complete set according to the classification, specification and freight weight. Different types can be used. Packing. No matter what packaging method is used, the packaging should be flat, firm and reliable. If there are special requirements, the manufacturer can negotiate with the user to determine. The product name, specifications, volume, weight and precautions for storage and transportation should be marked outside the packaging box. The product certificate should be attached inside the box. Technical documents must be bagged and sealed with plastic film.
Special-shaped steel expansion joint strips are products specially designed for various types of bridge expansion joints. All specifications and models are produced in accordance with the standards of the Ministry of Communications and the Ministry of Railways. It can be used with type, type, and type joints and other types of expansion joints Supporting the use of. Rubber expansion joints use the high elasticity of rubber to adapt to the expansion and contraction deformation of the bridge deck when temperature changes. Rubber expansion joints have the advantages of easy installation, smooth driving, waterproof, dustproof, low noise, light weight and low cost, and have been welcomed and praised by the bridge engineering community. and indicates the type of rubber, which indicates natural rubber, and indicates the applicable range of chloroprene rubber material. The expansion joint device using chloroprene rubber is suitable for areas with a temperature of +, and the expansion joint device using natural rubber is suitable for areas with a temperature of +
