Device for fixing dowel bar on concrete pavement and using method
The invention provides a device for fixing a dowel bar of a concrete pavement and a using method, the device comprises a fixing frame and an electromagnetic attraction assembly, the fixing frame is used for installing the electromagnetic attraction assembly on a road construction formwork, and the electromagnetic attraction assembly is used for magnetically attracting and fixing the dowel bar; the electromagnetic attraction assembly comprises a power supply device, an electromagnet and a mounting frame, the power supply device is electrically connected with the electromagnet, and the two ends of the mounting frame are connected with the fixing frame and the electromagnet respectively. The problems that in the concrete road construction process, due to concrete vibration and other external interference, the dowel bar deviates from the preset position, the arrangement precision of the dowel bar is reduced, but the effect of transmitting loads cannot be exerted, but the pavement joint is quickly damaged due to the difference of linear expansion coefficients of steel and concrete, and the service life of the dowel bar is prolonged can be effectively solved. And the service life of the concrete pavement is shortened.
本发明提供一种固定混凝土路面传力杆的装置及使用方法，所述装置包括固定架和电磁吸组件，所述固定架用以将所述电磁吸组件安装在道路施工模板上，所述电磁吸组件用以磁吸固定传力杆；所述电磁吸组件包括供电设备、电磁铁和安装架，所述供电设备电连接所述电磁铁，所述安装架的两端分别连接所述固定架和所述电磁铁。本发明可有效避免在混凝土道路施工过程中，因混凝土振捣及其他外界干扰导致传力杆偏离预设位置，使得传力杆布置精度降低，非但发挥不了传递荷载的作用，反而会由于钢材和混凝土的线胀系数差异而很快将路面接缝处顶坏，降低混凝土路面的使用年限的问题。
