The connection terminal portion 372 includes a connection portion 3721 having a substantially rectangular plane shape, a lightning conductor lead insertion portion 3722 having a cylindrical cross-sectional shape, and a gradient portion 3723 located therebetween. The connecting portion 3721 is joined to the iron plate thin plate portion 371 by a screw 371a. The lightning conductor lead insertion portion 3722 has the tip of the second lightning conductor inserted in the cylinder. The gradient portion 3723 is converted from a connection portion 3721 having a substantially rectangular planar shape into a lightning conductor insertion portion 3722 having a cylindrical cross section. The flat plate portion 373 has a screw hole (not shown) in which the outer peripheral portion thereof is brazed 3731 with brass and screwed into the screw 371 so as to overlap the substantially central portion of the iron plate thin plate portion 371.

以下、鉄筋用接続端子３７の施工方法について説明する。先ず、避雷導線挿入部３７２２の円筒内へ第二避雷導線３６の先端部を挿入したのちに避雷導線挿入部３７２２に付属するネジ３７２ａで固定する。次に、第二避雷導線３６と避雷導線挿入部３７２２の内壁間に生じた空隙にハンダを充填することによって接続端子３７２と第二避雷導線３６とを接合する。上記接続端子３７２と第二避雷導線３６との接合作業と並行して、平板部３７３を鉄板薄板部３７１の一方の平面部に取付ける。その鉄板薄板部３７１及び平板部３７３にネジ３７１を螺着させるネジ穴（図示せず）を加工する。 Hereinafter, the construction method of the connecting terminal 37 for reinforcing bars will be described. First, after inserting the tip part of the second lightning conductor 36 into the cylinder of the lightning conductor insertion part 3722, it is fixed with a screw 372a attached to the lightning conductor insertion part 3722. Next, the connection terminal 372 and the second lightning conductor 36 are joined by filling the gap formed between the second lightning conductor 36 and the inner wall of the lightning conductor insertion portion 3722 with solder.

Thereby, the reinforcing bar connection terminal 37 is joined to the reinforcing bar 32 constituting the reinforced concrete.

この技術はすでに商品化されており、周知の事実となっている。従来の文献としては引用すべきものは見当たらなかったが、建造物の地下室の外周に設けられる地下外壁面から浸透した水分が避雷導線を伝わって、地下内壁面への浸入するのを防止するようにした導線接続用水切り端子がある（例えば、特許文献１参照）。
特開２００１−４５６４３号公報（第１−３頁、第１図） This technology has already been commercialized and is a well-known fact. Although there was nothing that should be cited as a conventional document, water that permeated from the outer wall surface of the basement around the basement of the building was prevented from passing through the lightning conductor and entering the inner wall surface. There is a drain terminal for conducting wire connection (see, for example, Patent Document 1).

しかし、従来の水切り端子３５は型枠に穴を開け、その穴に帯板部３５１を挿入し番線で型枠に緊結されるため取付け精度を一定に保持することが困難であった。また、帯板部３５１はコンクリート打設前には型枠の表面から、コンクリート打設後にはコンクリート躯体から突出する為、施工時に於ける災害、例えば、突出した帯板部３５１による蹴躓き、眼球への突き刺さりを防止するために、受雷部３１と水切り端子３５を第一避雷導線３４によって接合する避雷設備工事に取り掛かるまでの間は壁側に折り曲げられている。しかし、その避雷設備工事の際に折り曲げられていた帯板部３５１を元に戻すと金属疲労によって帯板部３５１が切断されてしまい、避雷設備としての機能を果たし得ないばかりでなく、手直しの大きな要因となっていた。 However, since the conventional draining terminal 35 has a hole in the mold, and a band plate portion 351 is inserted into the hole and is tightly connected to the mold by a wire, it is difficult to keep the mounting accuracy constant. Further, since the band plate portion 351 protrudes from the surface of the formwork before the concrete is placed and from the concrete frame after the concrete is placed, a disaster during construction, for example, kicking by the protruding band plate portion 351, eyeball In order to prevent piercing, the lightning protection part 31 and the drainage terminal 35 are bent to the wall side until the lightning arrester construction for joining by the first lightning conductor 34 is started. However, if the band plate part 351 bent at the time of the lightning arrester construction is returned to the original state, the band plate part 351 is cut by metal fatigue, and not only can the function as a lightning arrester be performed, It was a big factor.
