Main Contents And Innovations

石家庄铁道大学联合河北庆维科技有限公司研发的公路桥梁单元式工字形钢梳齿型伸缩装置是国内首创新型伸缩装置，是以工字形钢为单元的一种伸缩装置，由工字形钢过梁、工字形钢固定件、角钢、圆钢销轴、圆钢支承组成。伸缩装置主材工字形钢过梁顺行车方向布置，外漏面不设置易损件，装置主要特点为以梁为基结构创新、纵向安装构造耐久、跨缝安装适应重载、行车平顺减振降噪、安装简洁便于维护。该装置在多个工程中推广应用，使用效果良好，得到了用户及业内专家的认可。

Unit I-Beam Sparse Plate Expansion Joint for Highway Bridge developed by Shijiazhuang Tiedao University in conjunction with Hebei Qingwei Technology Co., Ltd. is the first new expansion device in China. It is an expansion device with I-Beam as the unit, which is composed of I-Beam lintel, I-Beam fastener, angle steel, round steel pin shaft and round steel support. The main material of the expansion device, I-Beam lintel, is arranged along the traveling direction, and the exposed surface is not equipped with wearing parts. The main features of the device are the innovative longitudinal installation based on the I-beam structure, durable cross-joint installation, suitable for heavy traffic smooth vibration and noise reduction, simple installation and easy maintenance. The device has been popularized and applied in many projects with good application effect, and has been recognized by users and industry experts
