1 桥面伸缩缝装置的作用与理想伸缩缝的 判别指标 为使车辆平稳通过桥面并满足桥面变形,需要在桥面伸缩缝处设置一定的伸缩装置。这种装置称为桥面伸缩缝装置。 对桥面伸缩缝的设计与施工,应全面考虑下述要求: α.能够适应桥梁温度变化所引起的伸缩 除了考虑年较差温度变化所引起的伸缩外,还必须考虑施工时的温度所需调整的量,以便在全部的预期温度范围内都能可靠地工作。
A role of bridge deck joints and the ideal expansion joints to determine the indicators In order to make the vehicle smoothly through the deck and bridge deck to meet the deformation, the bridge deck joints need to set a certain telescopic device. This device is called bridge expansion joint device. The design and construction of the bridge expansion joints should fully consider the following requirements: α. To adapt to bridge expansion caused by temperature changes In addition to taking into account the year-to-year differential temperature caused by the expansion and contraction, but also must consider the construction of the temperature required Adjust the amount so that it will work reliably over the entire expected temperature range.
