  In addition, even if unexpected rainwater enters into the substantially sealed space 19 for some reason, the rainwater flows through the upper surface of the underfloor eaves top 20 and drains from the rainwater discharge port 91 of the underfloor eaves 20. After flowing into the body 92, it flows into the drain pipe 93 from the drain outlet 103 of the drainer 92 and is discharged.

  In addition, at the time of construction, for example, when the siding contractor installs the siding members 36, 37, 38 after completing the installation of the upper horizontally long base material 31, the lower horizontally long base material 32, the vertically long base material 33 and the like, It is not necessary to prepare an additional vertically long base material for position adjustment of the siding member 36 for construction at the construction site, and it is possible to attach the siding members 36, 37, 38 to appropriate positions using spacers 63, 73, etc. .

  And according to this building accessory 1, the rainwater intrusion prevention body 81 which prevents the intrusion of rainwater into the lower side of the floor portion 10 of the floor body 4 has one side on the building 2 side among the four sides of the floor portion 10. Since it is provided along the other three sides, rainwater can be prevented from entering the substantially sealed space 19 on the lower side of the floor 10. Therefore, for example, it is possible to prevent inconveniences such as rainwater accumulation in the substantially sealed space 19 and long-term rain dripping from the connecting portions of the eave roof materials 13 adjacent to each other.

  Further, even if unexpected rainwater enters the substantially sealed space 19 for some reason, the rainwater that has entered can be appropriately discharged to the outside through the drainage body 92 and the drain pipe 93, and the drainage body 92 Draining can be performed by the draining plate portion 98 of the above.

  Furthermore, the rainwater intrusion prevention body 81 provided along the three sides of the floor portion 10 includes a support plate portion 82 that supports the lower surface of the floor portion 10, and an upright plate portion 83 that is erected on the support plate portion 82. It is configured by an angle material having a substantially L-shaped cross section, so that rainwater can appropriately enter the space portion 19 on the lower side of the floor portion 10 despite the extremely simple and simple configuration. Can be prevented.

  On the other hand, unlike the conventional case, it is not necessary to adjust the position of the siding member 36 for the outer wall by using an additional vertically long base material, so that the siding contractor does not have to take time to install the siding members 36, 37, and 38. Therefore, the construction can be performed efficiently, and the workability can be improved.

  In addition, the upper and lower ends of the outer wall siding member 36 are attached to the upper and lower siding mounting convex portions 61 of the vertically long base material 33, and part of the horizontally long base materials 31 and 32 is inserted into the vertically long base material 33. By inserting into the concave portion 62, the outer wall siding member 36 and the horizontally long base materials 31 and 32 can be easily attached, and construction can be performed more efficiently.

  The building accessory 1 may be, for example, a balcony or a veranda without the staircase 7.

  Further, the floor 10 and the underfloor eaves 20 are not limited to those composed of a plurality of divided plates arranged adjacent to each other, and may be, for example, a single plate.

  Further, the siding members 22, 36, 37, and 38 may be of any type such as cement, ceramic, and metal. The material of the siding base materials 31, 32, 33 is preferably a metal material such as iron or aluminum.
