PROBLEM TO BE SOLVED: To provide a termite prevention agent spray device for a building and a termite prevention processing method capable of forming an effective termite prevention barrier layer to soil around the building, easily executing the restoration processing of a termite prevention effect reduced with time, and being easily executed not only to a newly constructed building but also to an existing building.SOLUTION: The termite prevention agent spray device includes first and second termite prevention agent spray pipes 10A, 10B, 10C, 10D, 10E, and 10F which have a supply port 12 for supplying a termite prevention agent R to the inside at one end 11a and a plurality of spray ports 13 for making the termite prevention agent R flow out to the outside on a peripheral wall 11c from the supply port 12 to the other end 11b, and for which the outflow amount of the termite prevention agent R flowing out from the plurality of spray ports 13 is reduced from the supply port 12 to the other end 11b. The first and second termite prevention agent spray pipes 10A, 10B, 10C, 10D, 10E, and 10F are arranged facing each other in parallel in such a state that the other end 11b of one is turned to the supply port 12 of the other and the other end 11b of the other is turned to the supply port 12 of one respectively.COPYRIGHT: (C)2012,JPO&INPIT【課題】建築物周囲の土壌に対し効果的な防蟻バリアー層を形成でき、経年減退した防蟻効果の復活処理を容易に行うことができ、新築時だけでなく既設の建築物に対しても容易に施工することができる建築物の防蟻剤散布装置及び防蟻処理方法を提供すること。【解決手段】一端11aに防蟻剤Rを内部に供給するための供給口12を、供給口12から他端11bに向かって周壁11cに防蟻剤Rを外部に流出させる複数の散布口13を有し、複数の散布口13から流出する防蟻剤Rの流出量が供給口12から他端11bに向かうに連れて減少する第1及び第2の防蟻剤散布パイプ10A、10B、10C、10D、10E、10Fを有する。第1及び第2の防蟻剤散布パイプ10A、10B、10C、10D、10E、10Fは、一方の他端11bが他方の供給口12に、他方の他端11bが一方の供給口12にそれぞれ向かった状態で、互いに並行に対向して配置されている。【選択図】図1
