Bridge expansion joints displacement control system, the elastic displacement control spring and its coordination in various movable beams and rubber sealing strip together to form a complete motion system (Figure 5-22). Control spring retractable path control of each unit within the gap, bridge expansion joints while elastic yield minus side of the decimal point its influence. Bridge expansion joint reaction force acting on the direction of displacement can be obtained by calculating the extreme. For the band-shaped sectional profile: compression 4KN / M, stretching 3KN / m; for the box-section type: compression 6KN / m, tensile 3KN / m. Nothing to do with the above limits the number of elements in the beam and stretching. Design engineers in the selection of the device can be determined based on the above principles notch size, specifies the value of recommendations, bridge expansion joints according to the standard for the new bridge expansion joint device slot reserved d80 without anchoring system design can also be spread installed after making an incision 120 Expansion Joints, when to replace the old bridge, there should be cleared of telescopic device, slot should be done as close to the standard slot size, steel bridge expansion joints should be cut transverse direction away, along the bridge can be retained to the reinforcement and vertical bars, bridge expansion joints but does not affect the placement should ensure cross stitch plate, and the bottom must be flat. Bridge expansion joints, seams in the form of the Duchy of multi-span bridge across a small bridge engineering works especially on the highway often used, which constitute a variety of forms. EPBC type bridge expansion, by Zhenjiang City, Jiangsu Province Highway Administration and Southeast University jointly developed the use of polymer composites as expansion joint filler bonding and structure, using less than 40mm below the bridge joints occasion bridge expansion joints of the product has received the exclusive right to the use of new countries in 1995. Highway Bridge Design in general specification stipulates that the temperature range of the bridge structure should be based on the temperature conditions of the bridge area may be, then determine the local maximum and minimum temperatures, reinforced and prestressed concrete structural steel can, generally based on the local monthly The average maximum and minimum temperatures OK. Production and sales of non-linear temperature gradient of temperature change specification by the majority of users enthusiastic praise. 120 MAURER expansion joints, expansion joints, ho-ho Rubber pass by Hengshui Rubber Company.
