A cable protection pipe structure of a building bottom slab is provided to facilitate construction of an electric wire by minimizing movement of a protection pipe in casting concrete. Two protection pipe support plate(20) are formed by flat panels in pairs and include bolt holes(21) and semicircular grooves(22). The bolt holes are penetrated to both sides in a longitudinal direction. The semicircular grooves are formed at one side in a width direction. A protection pipe(12) is inserted and supported into a circular hole formed by closely adhering the pair of the protection pipe support plate each other. The protection pipe support plates are inserted into grooves of two guide units(35) of a support(30). The guide units are separated from a top surface of a rectangular body(31) and include the grooves inside. A suspension rod(40) is suspended to a reinforcing rod(15) by being bent in a U shape and bending both sides in a state of passing through a suspension rod hole of the lower protection support plate by bending suspension units(41) at both sides in a longitudinal direction to be rounded. Anchors(50) are vertically installed by passing through anchor holes(34) of the rectangular body of the support by passing through rectangular flange units(24) of the protection pipe support plates. |
