Plural penetration holes 3a are formed in the side wall of a base 3, and ends 6a, 7a of reinforcements 6, 7 of an RC pavement 2 laid around the light embedded area are inserted into the penetration holes 3a, and the peripheral edge of each penetration hole 3a and the ends 6a, 7a of the reinforcements 6, 7 are firmly fixed by welding. Since the ends 6a, 7a of the reinforcements 6, 7 of the RC pavement 2 and the base 3 are mutually fixed, the load applied to the inset light 1 from above is dispersed not only into the portion contacting with the lower side of the base 3 of the RC pavement 2, but also into the reinforcements 6, 7, and the sinking shearing resistance of the RC pavement 2 is extremely improved. Accordingly, if a heavy load of aircraft or the like is applied, the inset light capable of preventing sinking of the RC pavement in the lower part of the base is presented.
An embedded structure of an inset light, being an inset light comprising a cylindrical base embedded in a reinforced concrete pavement, and a lamp body held on top of said base for emitting light to outside of the pavement surface, wherein end portions of the reinforcement of said reinforced concrete pavement and said base are fixed such that a load applied to the inset light from above is dispersed among a lower side of the base and the reinforcement of said reinforced concrete pavement.
An embedded structure of an inset light, being an inset light comprising a cylindrical base embedded in a reinforced concrete pavement, and a lamp body held on top of said base for emitting light to outside of the pavement surface, wherein holes are formed in a side wall of said base, and end portions of said reinforcement of the reinforced concrete pavement are inserted in said holes, and fixed by welding the end portions of the reinforcement and a peripheral edge of the hole.
