Description
【０００１】[0001]
この考案は升蓋の取付構造に関し、特にはコンクリート内に埋設される受枠に 対し升蓋を開閉自在に取り付ける構造に関する。 The present invention relates to a mounting structure for a lid, and more particularly to a structure for mounting a lid on a receiving frame embedded in concrete so that the lid can be opened and closed.
【０００２】[0002]
従来より、側溝に設けられる下水や雨水などの集排水部を覆う升蓋は、所定の 蓋形状に形成された枠板と前記枠板内に掛けわたされる桟材よりなり、コンクリ ートなどの施工部に埋設された受枠に対して、点検ならびに清掃などの必要性か ら開閉自在に取り付けられている。 Conventionally, the box lid that covers the drainage and drainage section for sewage and rainwater provided in the gutter is composed of a frame plate formed in a predetermined lid shape and a crosspiece that is hung inside the frame plate. It is attached to the receiving frame buried in the construction section so that it can be opened and closed freely for inspection and cleaning.
【０００３】 図１０および図１１に、このような升蓋の取り付け構造の従来例が示される。 両図中の符号５０は升蓋、５１は前記升蓋５０の枠板で桟材５２（主部材５２ａ およびツイストバー５２ｂともいう）が図のような格子状に形成されている。受 枠５３は前記升蓋５０が嵌め外し可能な枠形状に形成されており、下面には前記 升蓋５０を受ける受板部５４、両側部外面にはアンカー部５５が設けられている 。この受枠５３は、あらかじめコンクリートなどの中に埋設しておく場合もある 。前記升蓋５０は、前記受枠５３内に落とし込み、四方をボルト５６などで当該 受枠５３に固定される。符号５７は前記ボルト５６が螺着されるねじ孔である。 その際、スパナやボルトの挿入など前記ボルト５６による固定作業がしやすいよ うに、前記枠板５１の所定位置には、図のように、桟材５２の一部を切除した切 欠部分５８が必要となる。FIG. 10 and FIG. 11 show a conventional example of such a lid attachment structure. In both figures, reference numeral 50 is a box lid, 51 is a frame plate of the box lid 50, and crosspieces 52 (also referred to as main members 52a and twist bars 52b) are formed in a lattice shape as shown. The receiving frame 53 is formed in a frame shape into which the box lid 50 can be fitted and removed, and a receiving plate portion 54 for receiving the box lid 50 is provided on the lower surface, and anchor portions 55 are provided on the outer surfaces of both side portions. The receiving frame 53 may be embedded in concrete or the like in advance. The box lid 50 is dropped into the receiving frame 53 and is fixed to the receiving frame 53 by bolts 56 or the like on all four sides. Reference numeral 57 is a screw hole into which the bolt 56 is screwed. At this time, as shown in the drawing, a notched portion 58 obtained by cutting off a part of the crosspiece 52 is provided at a predetermined position of the frame plate 51 so that the fixing work by the bolt 56 such as insertion of a spanner or a bolt can be easily performed. Will be needed.
【０００４】 しかしながら、このような構造にあっては、前記桟材５２の切欠部分５８にハ イヒールのかかとなどが嵌まるなどの歩行上の問題があり、またこの切欠部分５ ８に小石やゴミが詰まって開閉作業がしにくくなるなどの問題があった。そのた め、施行責任者である公共団体によっては、図１１のように、当該切欠部分５８ にキャップ５９を嵌めることを要求することもある。しかしながら、このような キャップ５９の装着はコスト的にも作業的にも不利であるばかりでなく、使用に つれ破損したりやがて外れて紛失したりして、効果的にも満足できるものではな かった。However, in such a structure, there is a walking problem such as the heel of the high heel being fitted in the cutout portion 58 of the crosspiece 52, and the cutout portion 58 has small stones and dust. There was a problem that it became difficult to open and close due to clogging. Therefore, depending on the public organization that is the person in charge of enforcement, as shown in FIG. 11, it may be required to fit a cap 59 on the cutout portion 58. However, the mounting of the cap 59 as described above is not only disadvantageous in terms of cost and work, but it is not always satisfactory because it is damaged or eventually comes off and is lost during use. It was
【０００５】 そこで、近年、升蓋を受枠に回動自在に取り付けることにより、開閉させる構 造が提案され実施されている。その一例として例えば実開平６−７１５８２号公 報に示されるように、升蓋の両側板の後部に第１軸孔および第２軸孔を形成し、 受枠には、その一方の側板には前記第１軸孔に対応する固定ピンを受枠内方へ突 設し、他方の側板には前記第２軸孔に対応して、スプリング受け部材に収納され たスプリングによって受枠内に出入り自在に構成された可動ピンを設けることに よって、前記固定ピンに升蓋の第１軸孔を嵌め、次いで可動ピンに第２軸孔を嵌 め合わせるものである。Therefore, in recent years, a structure in which a lid is rotatably attached to a receiving frame to open and close has been proposed and implemented. As one example, as disclosed in Japanese Utility Model Publication No. 6-71582, a first shaft hole and a second shaft hole are formed in the rear portions of both side plates of the box lid, and the receiving frame has one side plate with the above-mentioned holes. A fixing pin corresponding to the first shaft hole is projected inward of the receiving frame, and the other side plate is configured to be able to move in and out of the receiving frame by a spring housed in a spring receiving member corresponding to the second shaft hole. By providing the movable pin, the first shaft hole of the box lid is fitted to the fixed pin, and then the second shaft hole is fitted to the movable pin.
【０００６】 上記のような構造によれば、ボルトが不要であるので、そのためのキャップな ども不要となるが、受枠にスプリング受け部材に収納されたスプリングによって 受枠内に出入り自在に構成された可動ピンを設ける必要があり、構造が複雑で部 品や製作上のコスト的な問題があった。また、この可動ピンを出入り自在に保持 するスプリングおよびスプリング受け部材のために受枠に突出部が形成されるの で、受枠をコンクリート固定するためのより大きいスペースが必要とされる。According to the above-mentioned structure, since the bolt is unnecessary, a cap for the bolt is not necessary, but the spring housed in the spring receiving member of the receiving frame allows the movable structure configured to freely move in and out of the receiving frame. Since it was necessary to provide pins, the structure was complicated and there were problems in terms of parts and manufacturing costs. In addition, since a protrusion is formed on the receiving frame for the spring and the spring receiving member for holding the movable pin in and out, a larger space for fixing the receiving frame to concrete is required.
【０００７】[0007]
この考案は、このような問題点を解決するために提案されたものであって、極 めて簡単な構造で升蓋を開閉自在に容易かつ確実に取り付けることができ、しか もボルトなどを必要としない、作業性にも経済性にも優れた升蓋の取付構造を提 供しようとするものである。 The present invention was proposed in order to solve such a problem, and with a very simple structure, the box lid can be easily and securely attached so that it can be freely opened and closed. The purpose of the present invention is to provide a mounting structure for the lid which is excellent in workability and economy.

すなわち、この考案の升蓋の取付構造は、コンクリート内に埋設される受枠に 対し升蓋を開閉自在に取り付ける構造であって、前記升蓋の両側板の後部にはそ れぞれ外側へ突出する長筒部が形成されており、前記受枠の両側板の前記長筒部 に対応する位置には、該長筒部内に回動および移動自在に収容される突部がそれ ぞれ形成されていることを特徴とする。 That is, the mounting structure of the cell lid of the present invention is a structure in which the cell lid is openably and closably attached to the receiving frame embedded in the concrete, and the rear portions of the both side plates of the cell lid respectively project outward. Long tubular portions are formed, and protrusions that are rotatably and movably housed in the long tubular portions are formed at the positions corresponding to the long tubular portions on both side plates of the receiving frame. It is characterized by being

It is a figure.
【００１０】 図１および図２に示されるように、升蓋１０は両側板１１，１１および前板１ ３と後板１４とによって所定の蓋形状に形成され、その内側には複数本の主部材 １５が並べて架け渡されている。符号１６は前記升蓋１０の強度を補強するツイ ストバーで、前記升蓋１０の上面を前記主部材１５の架け渡し方向に直交して設 けられ、前記升蓋１０の表面を格子状となす。As shown in FIGS. 1 and 2, the box lid 10 is formed into a predetermined lid shape by the side plates 11, 11 and the front plate 13 and the rear plate 14, and a plurality of main plates are provided inside thereof. The members 15 are arranged side by side. Reference numeral 16 is a twist bar that reinforces the strength of the lid 10, and the upper surface of the lid 10 is provided orthogonally to the bridging direction of the main member 15, and the surface of the lid 10 has a lattice shape. .
【００１１】 前記升蓋１０の両側板１１，１１の後部には、それぞれ長筒部２２，２２が形 成されている。この長筒部２２は、前記両側板１１，１１から外側へ突出した側 面視長円形状の筒体であって、後記受枠３０の突部４０，４０がそれぞれ容易に 収容され、内部で充分に回動することができる直径および深さを有している。な お、この実施例の長筒部２２は前記両側板１１後部に溶接によって固定されてい る。Long tube portions 22, 22 are formed at the rear portions of both side plates 11, 11 of the lid 10, respectively. The long tube portion 22 is an oval-shaped tube body in a side view that protrudes outward from the both side plates 11, 11, and the projecting portions 40, 40 of a receiving frame 30, which will be described later, can be easily accommodated therein, respectively, and are sufficiently internal. It has a diameter and a depth that allow it to be rotated. The long tubular portion 22 of this embodiment is fixed to the rear portions of the side plates 11 by welding.
【００１２】 一方、受枠３０は両側板３１，３１および前板３２と後板３３によって前記升 蓋１０が嵌め外し可能な枠形状に形成され、図２のようにあらかじめコンクリー トＣ内に埋設しておくことができる。それによって、前記コンクリートＣが受枠 ３０と一体となって硬化し、その養生が確実に終了してから升蓋１０の取付を行 うことができる。符号３４は前記升蓋１０を受ける受板部、３５はアンカー部で ある。On the other hand, the receiving frame 30 is formed by the side plates 31, 31, the front plate 32, and the rear plate 33 into a frame shape into which the box lid 10 can be inserted and removed, and is embedded in the concrete C in advance as shown in FIG. Can be kept. As a result, the concrete C is hardened together with the receiving frame 30 and the curing of the concrete C is completed, and then the box lid 10 can be attached. Reference numeral 34 is a receiving plate portion for receiving the box lid 10, and 35 is an anchor portion.
【００１３】 前記受枠３０において、前記升蓋１０の両側板１１，１１と対応する両側板３ １，３１には、前記升蓋１０の長筒部２２，２２に対応する位置に突部４０，４ ０が設けられている。この突部４０は、前記受枠３０の側板３１から内側に向か って突設された突部であって、升蓋１０が受枠３０に取り付けられる際には、前 記長筒部２２内に回動および移動自在に収容される。この突部形状は前記長筒部 ２２内において回動および移動可能であれば特に限定はなく、適当な幅（または 直径）および高さの角柱状や円柱状などである。In the receiving frame 30, the side plates 31 and 31 corresponding to the side plates 11 and 11 of the box cover 10 are provided with protrusions 40, at positions corresponding to the long tube portions 22 and 22 of the box cover 10. 40 are provided. The protrusion 40 is a protrusion protruding inward from the side plate 31 of the receiving frame 30. When the box lid 10 is attached to the receiving frame 30, the protrusion 40 is provided inside the long tubular portion 22. It is rotatably and movably accommodated. The shape of the protrusion is not particularly limited as long as it can rotate and move within the long tubular portion 22, and may be a prism or a cylinder having an appropriate width (or diameter) and height.
【００１４】 上記構造を有する升蓋１０および受枠３０にあっては、升蓋１０が長筒部２２ 内に収容された受枠３０の突部４０によって支持されており、該突部４０の前記 長筒部２２内における自在な回動および移動によって升蓋１０が自在に開閉する ように構成されている。In the box lid 10 and the receiving frame 30 having the above structure, the box lid 10 is supported by the protrusion 40 of the receiving frame 30 housed in the long tubular portion 22, and the length of the protrusion 40 is increased. The lid 10 is configured to open and close freely by freely rotating and moving in the tubular portion 22.
【００１５】 たとえば、升蓋１０の開蓋時には、図４ないし図７に示すように、前記突部４ ０を軸として前記升蓋１０が突部４０の周りを矢印ＢからＣ、更にはＤへと受枠 ３０の後方側へ回動する。そして、その回動にともなって前記突部４０が長筒部 ２２内の４０Ａの位置から４０Ｂの位置へ、更には４０Ｃの位置から４０Ｄの位 置へと上方から下方に順次移動して、前記升蓋１０の回動軸を適宜ズラしながら 非常に小さい回動半径で開蓋させるのである。 逆に、升蓋１０の閉蓋時には、前記突部４０を軸として前記升蓋１０が受枠３ ０の前方側へ回動するとともに、該突部４０が長筒部２２内の下方位置から上方 位置へ移動することによって、升蓋１０を小さい回動半径で閉蓋させるのである 。For example, when the lid 10 is opened, as shown in FIGS. 4 to 7, the lid 10 moves around the protrusion 40 around the protrusion 40 as indicated by arrows B to C, and further D. To the rear side of the receiving frame 30. Along with the rotation, the protrusion 40 sequentially moves from the position of 40A to the position of 40B in the long tubular portion 22 and further from the position of 40C to the position of 40D from the upper side to the lower side. The lid 10 is opened with a very small turning radius while appropriately shifting the turning axis of the lid 10. On the contrary, when the lid 10 is closed, the lid 10 rotates around the protrusion 40 toward the front side of the receiving frame 30, and the protrusion 40 moves upward from a lower position in the long tubular portion 22. By moving to the position, the lid 10 is closed with a small turning radius.
【００１６】 なお、この実施例のように、この長筒部２２を後部側が上部となる傾斜状に形 成した場合には、図４ないし図７に示したように、前記突部４０の回動時におけ る移動方向に長筒部２２が存することとなるため、突部４０の長筒部２２内にお ける移動がよりスムーズとなり、升蓋１０の開閉がよりスピーディーかつ容易と なる。 また、この例では、受枠の突部４０が升蓋の長筒部２２内の最下部（図７に示 す４０Ｄの位置）に移動すると、突部４０が長筒部２２の内周面に当接するとと もに、升蓋の後板１４の上部１４ａが受枠の底板３４上面３４ａに当接すること によって、升蓋１０を一定角度Ｎ（この例では１１０°）に固定することができ るように構成されている。When the long tubular portion 22 is formed in an inclined shape with the rear side being the upper side as in this embodiment, as shown in FIG. 4 to FIG. Since the long tubular portion 22 exists in the moving direction during the movement, the movement of the protrusion 40 in the long tubular portion 22 becomes smoother, and the opening and closing of the box lid 10 becomes faster and easier. Further, in this example, when the projecting portion 40 of the receiving frame moves to the lowermost portion (position 40D shown in FIG. 7) in the long tubular portion 22 of the box lid, the projecting portion 40 moves to the inner peripheral surface of the long tubular portion 22. In addition to abutting, the upper portion 14a of the rear plate 14 of the box lid comes into contact with the upper surface 34a of the bottom plate 34 of the receiving frame, so that the box lid 10 can be fixed at a constant angle N (110 ° in this example). Is configured.
【００１７】 さらにまた、この実施例では、図８からよく理解されるように、前記受枠３０ の側板３１にそれぞれ孔部３２が設けられており、この孔部３２に鍔付きボス４ １を差込固定することによって内側に突設する突部４０が形成されている。なお 、この鍔付きボス４１は、前記受枠３０の側板３１内周面から突出させるために 、側板３１の厚さより長く形成される。 勿論、この突部４０は、前記受枠３０の両側板３１，３１をあらかじめプレス 加工等により形成することもできる。Further, in this embodiment, as is well understood from FIG. 8, side plates 31 of the receiving frame 30 are provided with holes 32, respectively, and the bosses 41 with flanges are inserted into the holes 32. A protrusion 40 is formed so as to protrude inwardly by being fixedly inserted. The flanged boss 41 is formed longer than the thickness of the side plate 31 in order to project from the inner peripheral surface of the side plate 31 of the receiving frame 30. Of course, the protrusion 40 can be formed by pressing the both side plates 31, 31 of the receiving frame 30 in advance.
【００１８】 次に、この考案の升蓋１０の取り付け方法について説明する。 先ず、図９に示すように、前もってコンクリートＣ内に埋設された受枠３０の 突部４０ａを升蓋１０の長筒部２２ａ内に収容した状態で、升蓋１０を受枠３０ の受板部３４，３４上に嵌め込む。この際、長筒部２２ａが側板１１ａから突出 して設けられているため、作業者が上方からでも該長筒部２２ａの存在位置を認 識し易く、その長筒部２２ａ内への突部４０ａの収容は容易かつ確実である。Next, a method of attaching the box lid 10 of the present invention will be described. First, as shown in FIG. 9, with the projecting portion 40a of the receiving frame 30 previously embedded in the concrete C being housed in the long tubular portion 22a of the box lid 10, the box lid 10 is placed on the receiving plate portion 34 of the receiving frame 30. , 34. At this time, since the long tubular portion 22a is provided so as to project from the side plate 11a, it is easy for the operator to recognize the existing position of the long tubular portion 22a even from above, and the protruding portion into the long tubular portion 22a. The accommodation of 40a is easy and reliable.
【００１９】 次に、前記升蓋１０を前記突部４０ａの逆方向にズラして受枠３０の他方の突 部４０ｂを升蓋１０の他方の側板１１ｂに設けられた長筒部２２ｂ内に収容する 。この収容により、図２に示すように、前記長筒部２２，２２内に前記受枠の突 部４０，４０がそれぞれ回動および移動自在に収容され、升蓋１０が受枠３０に 対して開閉自在に取り付けられる。Next, the box lid 10 is slid in the opposite direction of the projecting portion 40a so that the other projecting portion 40b of the receiving frame 30 is housed in the long tubular portion 22b provided on the other side plate 11b of the box lid 10. To do. With this accommodation, as shown in FIG. 2, the protrusions 40, 40 of the receiving frame are rotatably and movably accommodated in the long tubular portions 22, 22, respectively, and the box lid 10 can be opened and closed with respect to the receiving frame 30. Attached to.
【００２０】[0020]
以上図示し説明したように、この考案の升蓋の取付構造によれば、升蓋をボル トまたはスプリングなど特別な部材を要することなく、極めて簡単な構造で受枠 に開閉自在に取り付けることができる。 従って、升蓋にボルトのための切欠を設ける必要がなく、靴のかかとなどが嵌 まるおそれがないだけでなく、キャップなどの別部材の調製およびその取付作業 も不要で極めて経済的である。 さらに、スプリングやその受け部材も不要であるので、経済的にも取付スペー ス等の施行上にも極めて有利である。 As shown and described above, according to the mounting structure of the box lid of the present invention, the box lid can be attached to the receiving frame to be openable and closable with a very simple structure without requiring a special member such as a bolt or a spring. . Therefore, it is not necessary to provide a notch for a bolt on the lid, and there is no fear that the heel of the shoe will be fitted, and preparation of another member such as a cap and its attaching work are unnecessary, which is extremely economical. Further, since the spring and its receiving member are not required, it is extremely advantageous economically and in terms of mounting space.
【００２１】 また、升蓋の長筒部が升蓋の側板の外側に突出しているため、作業者が上方か ら該長筒部の存在位置を認識し易く、この長筒部内に受枠の突部を容易かつ確実 に収容することができるという利点もある。Further, since the long tubular portion of the cell lid projects to the outside of the side plate of the cell lid, it is easy for an operator to recognize the existing position of the long tubular portion from above, and the receiving frame is projected into the long tube portion. There is also an advantage that the parts can be easily and reliably stored.
