Bridge expansion joints displacement control system bridge expansion joints displacement control system consists of a waterproof rubber band stretching and displacement control system. Bridge expansion joints with flexible control system, that is, between the beams and the beam has a pole elastic element, the displacement of the pole by turning the control of the beam, as shown in Figure 5-9. That is the use of a lever-type displacement control system, a set of beams by a lever connected, placed rubber elastic element leverage and bridge expansion joints between beams, while the middle beam telescopic joints beams longitudinal displacement angle d40 price, leverage and between the beams absorbed by the rubber elastic element supply d40 joints, levers to deliver the level of force and displacement through a connecting rod connected to the control box, there are rubber elements to absorb the connecting rod angle displacement of bridge expansion joints between the connecting rod and the control box, to achieve displacement control, to achieve Each seam uniform stretching. Bridge expansion joints are generally applicable to a small stretch to close the seam that kind of bridge, a necessary condition for its type in the structure beam length is shorter, the small amount of stretching their birdie also smaller, but do not worry about cracking or breakage Deck The bridge project. This seam is usually applied to the asphalt deck, and for the concrete bridge deck should generally be used with caution. The main reason is this type of bridge expansion joints and seams construction features is the use of asphalt mixes telescopic nature instead reserved sawn groove joint material, and when this mixture by a specialized company with a special tie in, it is difficult As a general material got, so only a small amount of use, while the situation before and after the bridge deck construction generally be selected according to the bridge. Bridge expansion joints on the following aspects of this joint has its own special requirements, the mixed material should be waterproof seams, waterproof seams when a wind of good material, and wall bonding and strong, can withstand repeated stretching, can cope with considerable variation large elongation and resilience of the material with a waterproof seam material is generally the best available room temperature, poured into the type of elastic joint material. According to foreign experience d40 joints, as shown in its general nature. Waterproof seams material in the construction must fully consider increasing their cohesiveness. Bridge expansion joints perpendicular to the sun's rays are most intense direct radiation in the summer and winter weakest, and subject to the transparency of the atmosphere. Part of the structure of the solar radiation is absorbed in part by the outside of the reflective structure. Solar heat is absorbed so that the bridge structure to avoid temperature rises, and gradually transferred to the internal structure of factory outlets d40 expansion joints, bridge expansion joints are also part of the heat and the ambient air due to the structure of the wall between the convective and radiative heat teach bad and made losses . Convective heat exchange with the surface of the structure in addition to the custom increases. During the day, the structure of the heat from the outside into the net, bridge expansion joints so that the temperature rise of the bridge structure, on the contrary, the heat in the night, storage and structure due to structural surface temperature above the ambient air temperature, the convective heat exchange and radiant heat exchange and thermal cooling.
