Main Contents And Innovations

石家莊鐵道大學聯合河北慶維科技有限公司研發的公路橋梁單元式工字形鋼梳齒型伸縮裝置是國內首創新型伸縮裝置，是以工字形鋼為單元的一種伸縮裝置，由工字形鋼過梁、工字形鋼固定件、角鋼、圓鋼銷軸、圓鋼支承組成。伸縮裝置主材工字形鋼過梁順行車方向布置，外漏面不設置易損件，裝置主要特點為以梁為基結構創新、縱向安裝構造耐久、跨縫安裝適應重載、行車平順減振降噪、安裝簡潔便于維護。該裝置在多個工程中推廣應用，使用效果良好，得到了用戶及業內專家的認可。

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
