环境温度的变化直接影响着型架尺寸的准确性和协调性,对于有尺寸协调要求的较大型的型架,温差影响已经成为设计和工艺上不可忽视的重要因素之一。大型型架的结构梁多数是分段组装或组合而成的。分段数量和各段的长度,都是由型架设计员决定的,由于没有统一的科学的分段原则,从而造成即使有长度协调要求的几台型架,
The change of ambient temperature has a direct impact on the accuracy and coordination of the size of the frame, and the influence of the temperature difference on the large-sized frame that has the requirements of the size coordination has become one of the important factors that can not be neglected in the design and the process. Most of the large-scale structure beam structure is assembled or combined by sub-section. The number of sections and the length of each section are determined by the designer of the frame. Due to the lack of a uniform and scientific principle of sectioning, several types of frames are required even if the length coordination is required.
