Bridge expansion joints sectional arrangement shown in Figure 5-11. Its series of specifications and dimensions parameters in Table 5-4 of the cases. Bridge expansion joints are generally applicable to a small stretch to close the seam that kind HZF140 bridge bridge expansion joints, the necessary conditions on the structure of formula beam length is shorter, the small amount of stretching their birdie also smaller, but do not worry bridge surface cracking or breakage of the bridge project. This seam is usually applied to the asphalt deck HZF180 bridge expansion joints, 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 of sawn groove joint material reserve bridge expansion joints, and by specialized companies with the proceeds of such special mix , it is difficult to get a general material and, therefore, only a small amount of use, but in general according to the situation before and after the construction of the bridge deck pavement be selected. 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, 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, 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 from the outside into the net heat HZF bridge expansion joints bearings, 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.
