PRECAST CONCRETE PANEL FOR PAVING ROAD AND METHOD FOR QUICKLY PAVING ON ROAD OF DOWNTOWN AREA

摘要

The present invention relates to a precast concrete panel and a rapid repair and pavement method using the precast concrete panel. The present invention relates to a precast concrete panel, a method of assembling a plurality of precast concrete panels in a prefabricated manner to pack roads (urban roads, airports, ports, It is easy to work, and a solid connection is possible, and the connection part is not exposed to the road surface and the flatness of the road surface is maintained. A precast concrete panel according to the present invention comprises: a first panel (10) having a plurality of well bars (12) protruding from a periphery; And a second panel (20) having a grooved connection portion (22) formed in a block - out shape opened to the lower portion in the periphery, wherein the first and second panels are alternately and repeatedly applied so that the dowel bars The first panel is formed by placing a concrete into a first panel body (11) having a plate shape, and a second panel body And a plurality of dowel bars (12) protruding from the periphery of the first panel body toward the lateral direction of the first panel body. The second panel comprises a plate-like second panel body (21) 2, a plurality of reinforcing bars 23 are formed in a block-out shape which is opened toward the bottom, leaving the upper finish layer 25 so that grouting is performed along with the ground while the dowel bars are inserted into all the circumferential portions of the panel main body. And a grouting hole (26) formed through the grouting connection part (22), which is vertically penetrated through the upper end of the grouting connection part, to fill the grouting part with the grouting material and the overeat hole (27). The precast concrete panel of the present invention comprises: a plate-like panel body 110 formed by pouring concrete; A plurality of dowel bars (120) protruding from a periphery of the panel body toward the lateral direction of the panel body; A grouting connection part 130 formed in a block-out shape opened to the bottom so as to be grouted together with the ground while the dowel bar is inserted into the remaining circumferential part of the panel body, and a plurality of reinforcing bars are arranged; A grouting hole formed in the upper portion of the upper portion of the grouting connection portion so as to fill the grouting portion with the grouting material, and an overit hole, wherein a plurality of the grouting holes are arranged in a plurality of rows and columns, And is grooved and packed so as not to be exposed to the top.
