また、本発明にかかる閉蓋固定構造では、連結ボルト挿通孔から圧接体上方に突出した連結ボルト及び連結ボルトに螺合締付けする締付けナットはいずれも上蓋ブロックに設けた上面通水孔から締め付け解除操作が可能となるような上面通水孔と相対する位置に配設したことを特徴とする。 Further, in the closed lid fixing structure according to the present invention, the connecting bolt protruding upward from the connecting bolt insertion hole and the tightening nut screwed and tightened to the connecting bolt are both released from the upper surface water passage hole provided in the upper lid block. It is characterized in that it is arranged at a position facing the upper surface water passage hole so that it can be operated.

請求項１に係る発明によれば、側溝ブロックの天端に蓋連結用の側溝用金具を埋設しその上面はブロック表面と面一で露出状態とし、上蓋ブロックの側縁底面に平板状の圧接体からなる上蓋用金具を埋設しその表面はブロック表面と面一で露出状態とし、側溝ブロックに上蓋ブロックを閉蓋した状態で側溝用金具の露出面と上蓋用金具の露出面とを上下当接接合状態になるように構成し、側溝用金具は、両金具を連結する連結ボルトと、連結ボルトの基部に設けた雄ネジ摺動体と、雄ネジ摺動体を収納して、雄ネジ摺動体に立設した連結ボルトを筒体長手方向の長手切欠部分を介してスライド可能とした雌ネジ筒体とより構成したことにより、上蓋用金具の平板状の圧接体に設けた連結ボルト挿通孔から上方に突出した連結ボルトの位置を変更したい時、すなわち、連結ボルトによる側溝ブロックと上蓋ブロックとの接合固定位置を変更したい時には連結ボルトを立設した略半円弧状の雄ネジ摺動体を雌ネジ筒体の連結ボルト摺動用溝部に沿ってスライドしながら位置変更することができる。 According to the invention according to claim 1, a side groove fitting for connecting a lid is embedded in the top end of the side groove block, the upper surface thereof is exposed flush with the block surface, and a flat plate-shaped pressure welding is performed on the bottom surface of the side edge of the upper lid block. The upper lid metal fittings made of the body are embedded and the surface is exposed flush with the block surface, and the exposed surface of the side groove metal fittings and the exposed surface of the upper lid metal fittings are vertically pressed with the upper lid block closed in the side groove block. The side groove fittings are configured to be in a tangential state, and the side groove fittings include a connecting bolt that connects both fittings, a male screw sliding body provided at the base of the connecting bolt, and a male screw sliding body. By constructing the connecting bolt erected in the above with a female screw cylinder that can slide through the longitudinal notch in the longitudinal direction of the cylinder, the connecting bolt insertion hole provided in the flat plate-shaped pressure welding body of the upper lid fitting can be used. When you want to change the position of the connecting bolt that protrudes upward, that is, when you want to change the joint fixing position between the side groove block and the top lid block by the connecting bolt, use a female screw with a substantially semi-arc-shaped male screw sliding body on which the connecting bolt is erected. The position can be changed while sliding along the sliding groove of the connecting bolt of the cylinder.

しかも、上蓋ブロックの上蓋用金具の圧接体を連結ボルトと締付けナットを介して側溝用金具に圧接すればするほど略半円弧状の雄ネジ摺動体は雌ネジ筒体の連結ボルト摺動用溝部内で互いのネジ溝を介して緊締な密着状態を生起し不用意に連結ボルト摺動用溝部内で位置ずれする虞を防止することができる。 Moreover, the more the pressure welding body of the upper lid metal fitting of the upper lid block is pressed against the side groove metal fitting via the connecting bolt and the tightening nut, the more the semi-arc-shaped male screw sliding body is inside the connecting bolt sliding groove of the female screw cylinder. It is possible to prevent a possibility that a tight close contact state is caused through the screw grooves of each other and the position is inadvertently displaced in the groove portion for sliding the connecting bolt.

しかも、連結ボルトの位置変更操作に際しては連結ボルトと締付けナットの弛緩により連結ボルト摺動用溝部内で略半円弧状の雄ネジ摺動体を容易にスライドすることができ両ブロックの連結ボルトの位置変更が可能となる効果がある。 Moreover, when changing the position of the connecting bolt, the loosening of the connecting bolt and the tightening nut allows the substantially semicircular male screw sliding body to easily slide in the groove for sliding the connecting bolt, and the position of the connecting bolt of both blocks can be changed. Has the effect of being possible.

また、請求項２に係る発明によれば、側溝用金具には側溝用アンカーを垂設し、上蓋用金具には蓋用アンカーを立設したことにより、各金具を各ブロック内に確実に埋設固定することができる効果がある。 Further, according to the second aspect of the present invention, the gutter anchor is vertically installed in the gutter metal fitting, and the lid anchor is erected in the upper lid metal fitting, so that each metal fitting is surely embedded in each block.

この発明の実施例を図面に基づき詳説する。図１は本発明の閉蓋固定構造を備えた側溝用ブロックと上蓋用ブロックの構成を示す全体斜視図、図２及び図３は側溝用ブロックの構成を示す斜視図及び平面図、図４及び図５は側溝用金具の構成を示す斜視図及びＡ－Ａ断面図、図６は上蓋用ブロックの構成を示す斜視図、図７及び図８は上蓋用ブロックの構成を示す拡大平面図及び拡大底面図、図９は上蓋用金具の構成を示す斜視図、図１０は側溝用金具と上蓋用金具との上下当接接合状態を示す模式的断面図である。 Examples of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall perspective view showing the configuration of a side groove block and an upper lid block provided with the lid closing structure of the present invention, and FIGS. 2 and 3 are a perspective view and a plan view showing the configuration of the side groove block, FIGS. 4 and 4. 5 is a perspective view and a sectional view showing the structure of the side groove fitting, FIG. 6 is a perspective view showing the structure of the upper lid block, and FIGS. 7 and 8 are an enlarged plan view and an enlarged view showing the structure of the upper lid block. A bottom view, FIG. 9 is a perspective view showing the configuration of the upper lid metal fitting, and FIG. 10 is a schematic cross-sectional view showing a vertical contact joint state between the side groove metal fitting and the upper lid metal fitting.

側溝用金具１０は、側溝ブロック１の金型成型時にブロック用金型にコンクリートを流入する時一体に埋設する。その際に側溝用金具上面１０ａは、図２及び図３に示すように側溝ブロック表面１ａと面一で露出するように埋設する。 The gutter metal fitting 10 is integrally embedded when concrete flows into the block mold when the gutter block 1 is molded. At that time, the upper surface 10a of the gutter metal fitting is embedded so as to be exposed flush with the gutter block surface 1a as shown in FIGS. 2 and 3.

側溝用金具１０は、図４に示すように雌ネジ筒体１１の少なくとも断面中央線Ｃよりも略上方部分を筒体長手方向に沿って切削し、この長手切削部分を連結ボルト摺動用溝部１２とすると共に、雌ネジ筒体１１中には略半円弧状の雄ネジ摺動体３０を位置調整自在に収納している。 As shown in FIG. 4, the side groove fitting 10 cuts at least a portion substantially above the center line C of the female screw cylinder 11 along the longitudinal direction of the cylinder, and the longitudinally cut portion is cut along the longitudinal direction of the cylinder, and the longitudinally cut portion is cut into the connecting bolt sliding groove portion 12. In addition, a male screw sliding body 30 having a substantially semi-arc shape is housed in the female screw cylinder 11 so that the position can be adjusted.

しかも、雄ネジ摺動体３０は、図４（ａ）及び図５に示すように雄ネジ本体を略半円弧状に切削した形状であるためにその半円弧周面にも雄ネジ溝１３ａが形成されている。 Moreover, since the male screw sliding body 30 has a shape in which the male screw body is cut into a substantially semicircular arc as shown in FIGS. 4A and 5, a male screw groove 13a is also formed on the peripheral surface of the semicircular arc. Has been done.

従って、雌ネジ筒体１１中には略半円弧状の雄ネジ摺動体３０を位置調整自在に収納すると雌ネジ筒体１１中の雌ネジ溝１１ａと雄ネジ摺動体３０外周面の雄ネジ溝３０ａとが、図４（ａ）及び図４（ｂ）に示すように後述する連結ボルト３１と締付けナット３２との螺合締付け操作によって互いのネジ溝１１ａ、３０ａが不規則に噛み合い強固な一体固定状態を現出する。 Therefore, when the male screw sliding body 30 having a substantially semi-arc shape is housed in the female screw cylinder 11 so that the position can be adjusted, the female screw groove 11a in the female screw cylinder 11 and the male screw groove on the outer peripheral surface of the male screw sliding body 30 are stored. As shown in FIGS. 4A and 4B, the screw grooves 11a and 30a are irregularly meshed with each other by the screw tightening operation of the connecting bolt 31 and the tightening nut 32 described later, and the 30a is firmly integrated. Reveals a fixed state.

一方で、連結ボルト３１と締付けナット３２との螺合締付けが弛緩した状態では雌ネジ筒体１１中で雄ネジ摺動体３０が容易にスライド可能となる。 On the other hand, in a state where the screw tightening between the connecting bolt 31 and the tightening nut 32 is loosened, the male screw sliding body 30 can be easily slid in the female screw cylinder 11.

雌ネジ筒体１１の前後端には前後開口部を閉塞して雄ネジ摺動体３０を規制する規制板体１６、１６’を設けている。なお、図４（ａ）中、符号１６ａ及び符号１１ｂは規制板体１６を雌ネジ筒体１１に固定するためのネジ孔である。 Restriction plates 16 and 16'are provided at the front and rear ends of the female screw cylinder 11 to close the front and rear openings to regulate the male screw sliding body 30. In FIG. 4A, reference numerals 16a and 11b are screw holes for fixing the regulation plate body 16 to the female screw cylinder body 11.

本発明は、かかる状態の雌ネジ筒体１１と略半円弧状の雄ネジ摺動体３０の収納関係状態を要旨とするものであり、互いにスライド可能に位置調整出来るが連結ボルト３１と締付けナット３２との螺合締付けにより雌ネジ筒体１１と略半円弧状の雄ネジ摺動体３０とを密着係合して強固な一体密着構造とすることができる。 The gist of the present invention is the storage-related state of the female screw cylinder 11 and the substantially semi-arc-shaped male screw sliding body 30 in such a state, and the positions can be adjusted so as to be slidable with each other, but the connecting bolt 31 and the tightening nut 32 are present.
