TS-type bridge expansion joint device bridge expansion joints, Tianjin and the Tianjin Institute of Municipal Engineering Administration jointly developed highway, bridge expansion joints to adapt to the amount in the range of 80 ~ 800mm modulus Series products. The structure is mainly composed of the following components: a system of bridge expansion joints sealed waterproof neoprene sealing tape, layering and layering bolt structure, shown in Figure 5-7. 2, bridge expansion joints and anchoring systems side edge beam beams and anchoring system for the whole group, weldments, from the edge of the beam body, side beam anchors (anchor plate and anchor ring), the box (package box welded anchor extension bolts, single slit is no such member) components. 3, the intermediate beams and elastic support system supporting beam bridge expansion joint system consists of a rigid connection of the upper and lower bearing pads, control spring, namely the middle beam horizontal arrangement of the highway bridge expansion joints, each intermediate beam spacing of 1600mm fixed number of roots support beam (beam - Editor's note), and to ensure the stability of motion in the middle of the beam. Girder bridge expansion joints installed in the sliding elastic support mat. 4 lateral displacement control system bridge expansion joints lateral displacement control system consists of the guide sleeve, slide the middle of the beam axis and given their rings. The system is designed for the intermediate beam sports-oriented, while the middle beam transverse displacement, control its maximum displacement, keep the beam ends neatly arranged bridge expansion joints, sealing tape to ensure that each absorbed ± 50mm shift amount. According to the principle structure of TCS-filled thermoplastic elastomer bridge joints, and must strictly adhere to all the major aspects of construction, bridge expansion joints should generally use embedded squeeze good stiff presentation of processed gravel, bridge expansion joints for the main layer specifications 20-40mm, the surface layer of 5-10mm, and requested its value is not more than 30% crushed, flattened and elongated stone content should be less than 15% -20%, and must use special equipment for heating, the heating temperature should be controlled 100-150, bridge expansion joints dedicated RS composite rubber, the heating temperature in the 190-210, short of 230, the temperature shall not exceed 2h, should pay attention to more than three in the wind, temperature, weather conditions lower than 10, not construction, for a different amount of stretching the comb plate bridge expansion joints, which according to the material per meter of different slot sizes, bridge expansion joints thermoplastic elastomer material single slit-type bridge expansion joints, in fact, the construction process can be roughly in accordance with the grooving , clear tank, drying notch, painted adhesive, gravel heating, paving gravel, pouring RS line with rubber, leveling is complete. For ease of calculation analysis and practical application, accustomed to the temperature bridge structure changes due to the above causes is subdivided into two parts. Bridge expansion joints linear and nonlinear temperature changes temperature changes in the design of the bridge structure, should consider the effect of temperature, telescopic structure which accounted for bridge expansion joints linear temperature changes caused by stretching the entire bridge structure of the vast amount section. Analysis of the role of linear temperature variation of the bridge structure, shut-in to determine the temperature variation of the bridge structure, the highest value and the lowest effective temperature effective temperature values.
