Claims (1)

[Claims for Utility Model Registration] A heat insulating board for a floor that is fitted between adjacent joists 2, 2, in which the upper surface 3 can be brought into substantially close contact with the lower surface 6 of the floor board 5, and the central portion 3a of the upper surface is formed to have a raised height. One of the opposing edge portions of the rectangular plate-shaped main body 7 is provided with a cutout groove 19, and the other side is provided with a cutout protrusion 20 that can fit into the cutout groove 19, and When the floor heat insulating boards are connected to each other by the fitting between the slit protrusion 20 and the slit groove 19, the opposing surfaces 25 of the slit protrusion 20 and the slit groove 19
, 26, between opposing surfaces 31, 32, opposing surfaces 33, 3
Waterway gaps g1, g2, g3 communicating with each other are formed between the main body upper surface 3, and the waterway gaps g1, g2, g3 are formed so that the communicating waterway gaps serve as a bent drainage channel 39 for draining rainwater flowing down the main body upper surface 3.
The end surface 27 on the side of the slit protrusion and the end surface 29 on the side of the slit groove are in contact with each other with the protrusion 30 for forming a channel gap, which is integral with the main body 7, interposed therebetween, and the lower surface 22 of the slit protrusion and the end surface 29 of the slit groove The upper surface 23 is defined by the protrusion 20
Alternatively, a heat insulating board for a floor is characterized in that it comes into contact with either one of the defined grooves 19 with a protrusion 21 for forming a channel gap interposed therebetween.
