A tray structure of an electric cable for a building is provided to facilitate construction by inserting the electric cable into a groove in state of installing a lower block, a meddle block, an upper block, and a cover plate on a base plate. A base plate(20) is fixed on a lower surface of a concrete slab by an anchor pin(30) and includes a U-shaped plate unit(21), a plurality of parallel plate units(22), a bent plate unit(23), a plurality of vertical holes, and an insertion groove(25). An upper block(40) includes a plate body unit(41), guide grooves(42), and a plurality of semicircular grooves(43). The guide grooves are inserted and closely adhered to the top parallel plate of the U-shaped plate unit and formed on both sides of the plate body unit in a U-shaped. The plurality of semicircular grooves is formed on top and bottom surfaces of the plate body unit. A middle block(50) is positioned on a lower surface of the upper block and includes a plate body unit(51), a guide groove(52) and a plurality of semicircular grooves(53). The guide grooves are formed on both sides of the plate body unit in a U-shaped and inserted and closely adhered to the parallel plate unit. The plurality of semicircular grooves is formed on a top surface of the plate body unit. A lower block(60) is closely adhered on the lowest bottom surface of the U-shaped plate unit of the base plate and includes a body(61) and a plurality of cable circular holes(62). A cover plate(70) includes a plate body unit(71), vertical projection units(72), and a plurality of semicircular grooves(73). The vertical projection units are inserted and received into/on the insertion groove and projected on a bottom surface of the plate body unit. The plurality of semicircular grooves is formed between the vertical projection units. |
