Description

本発明は、出入口の床面に埋設された、収納凹部体の開口を閉塞する倒伏位置から前記出入口を閉塞する起立位置に回動させるようにした防水扉装置に関する。 The present invention relates to a waterproof door device that is embedded in a floor surface of an entrance / exit and is rotated from a lying position that closes an opening of a storage recess to an upright position that closes the entrance / exit.

従来、地下空間等への水侵入可能な出入口の床面に配設されており、前記出入口の床面に収納凹部体を埋設し、防水扉を前記収納凹部体の開口を閉塞する倒伏位置から前記出入口を閉塞する起立位置に回動させるようにした防水扉装置として、特許文献１のものが知られている。この防水扉装置は、防水扉の下面に曲がり防止用の複数本のリブを備え、収納凹部体には、前記リブを支持するための支持壁がモルタルによって設けられている。防水扉を前記倒伏位置とした状態では、前記リブが支持壁に当接して防水板の上に自動車等の重量物が通過して大きな荷重が作用しても荷重を支えられるようになっている。
特開２００５−１３３２９０号公報 Conventionally, it is arranged on the floor surface of the entrance / exit where water can enter into the underground space, etc. Patent Document 1 discloses a waterproof door device that is rotated to an upright position that closes the doorway. This waterproof door device includes a plurality of ribs for preventing bending on the lower surface of the waterproof door, and a support wall for supporting the ribs is provided by mortar in the housing recess.

JP 2005-133290 A

しかしながら、特許文献１に記載の防水扉装置は、防水扉を倒伏位置とした状態で防水扉と収納凹部体との隙間の調整ができない構造となっていた。即ち、倒伏位置でリブと支持壁との隙間の調整ができず、リブと支持壁間に隙間ができたり、防水扉が床面より上がってしまっていた。そのため隙間ができると、防水扉を倒伏位置とした状態で防水扉と収納凹部体との間にがたつきが発生することがあった。また、従来の防水扉装置では、上記の隙間によって防水扉の耐荷重が減少し、大型車両通過の際には数ｍｍの隙間により振動が発生し防水扉装置の部品の故障の原因となったり、部品の緩みを引き起こす有害な振動を発生させるという問題があった。したがって、リブを太くする等して防水扉の強度を高める必要があり、防水扉が重くなる問題があった。
そこで、本発明の課題は、上記問題点に鑑みなされたものであって、防水扉を倒伏位置とした状態において、防水扉と収納凹部体との間に支持装置を設け、支持装置を介して防水扉を支持することで隙間を防止でき、防水扉が軽く耐荷重が大きな防水扉装置を提供することを目的とする。 However, the waterproof door device described in Patent Document 1 has a structure in which the clearance between the waterproof door and the housing recess cannot be adjusted in a state where the waterproof door is in the lying down position. That is, the gap between the rib and the support wall cannot be adjusted at the lying position, and a gap is formed between the rib and the support wall, or the waterproof door is raised from the floor surface. For this reason, if there is a gap, rattling may occur between the waterproof door and the housing recess in the state where the waterproof door is in the lying down position. Also, in the conventional waterproof door device, the load resistance of the waterproof door decreases due to the above-mentioned gap, and vibration occurs due to a gap of several mm when passing through a large vehicle, which may cause a failure of the waterproof door device parts. There has been a problem of generating harmful vibrations that cause loosening of parts. Therefore, it is necessary to increase the strength of the waterproof door by increasing the thickness of the ribs, and there is a problem that the waterproof door becomes heavy.
Then, the subject of this invention was made in view of the said problem, Comprising: In the state which made the waterproof door the fall position, a support apparatus was provided between the waterproof door and the accommodation recessed part, and the support apparatus was interposed. It is an object of the present invention to provide a waterproof door device that can prevent a gap by supporting the waterproof door and is light in weight and heavy in load resistance.

Then, the waterproof door 3 in the standing position B is pressed against the door frame 6 by the lock device 8. The waterproof door 3 is raised at the standing position B and pressed against the door frame 6 to prevent water from entering and exiting.

次に、防水扉装置１の防水扉３と収納凹部体２との間の調整作業について説明する。防水扉３は通常の状態では、収納凹部体２の開口を閉塞する倒伏位置Ａにある。この防水扉３が倒伏位置Ａにある状態で、防水扉３は、支持装置２３により、防水扉３の上面と床面Ｆとが段差が無くなるようにに調整されると共に防水扉３と収納凹部体２との間に隙間ができず防水扉３が支持されるように調整される。このために防水扉３が倒伏位置Ａにある状態で、防水扉３の下面と支持本体２４の距離が調整される。先ず、操作部２６の蓋用ボルト４０を外してボルト３１をボス部材３０から抜脱する。このときパッキン部材３２もボルト３１と一体にボス部材３０の大径孔２８ａから離脱される。 Next, an adjustment operation between the waterproof door 3 and the housing recess 2 of the waterproof door device 1 will be described. In a normal state, the waterproof door 3 is in a lying position A that closes the opening of the housing recess 2. With the waterproof door 3 in the lying position A, the waterproof door 3 is adjusted by the support device 23 so that there is no step between the upper surface of the waterproof door 3 and the floor surface F, and the waterproof door 3 and the storage recess. Adjustment is made so that there is no gap between the body 2 and the waterproof door 3 is supported. For this reason, the distance between the lower surface of the waterproof door 3 and the support body 24 is adjusted in a state where the waterproof door 3 is in the lying position A. First, the lid bolt 40 of the operation unit 26 is removed, and the bolt 31 is removed from the boss member 30. At this time, the packing member 32 is also detached from the large-diameter hole 28 a of the boss member 30 together with the bolt 31.

そして、操作孔２８上方向から工具を挿通する。工具は例えばレンチである。その工具によりネジ部材３５を回動させるとネジ部材３５は防水扉３から下方向に伸びて、ネジ部材３５の先端を支持本体２４の上面に当接させる。そして、更にネジ部材３５を回動させて防水扉３の上面と床面Ｆとを略同一面とする。このとき、防水扉３を倒伏位置Ａとした状態で防水扉３を収納凹部体２に当接する調整作業が行えるので、調整作業が容易となり、かつ短時間で行うことができる。また、ネジ部材３５を操作して支持本体２４に当接して防水扉３と収納凹部体２の隙間の調整作業が可能なので、隙間調整を精度よく行うことができる。次に、その状態で防水扉３を起立位置Ｂとしてナット３６を締め付けてネジ部材３５をロックする。そして、座金３７の舌３７ａを折り曲げてナット３６の外面に隣接させてナット３６が緩まないようにする。その後、再び防水扉３を倒伏位置Ａとして操作孔２８にボルト３１とパッキン部材３２を装着して水密としているので、洪水時に防水扉３を起立位置Ｂとしても操作孔２８からの浸水を防げる。この調整のとき、防水扉３の倒伏位置Ａと起立位置Ｂとの移動は１回ですむ。また、長年の使用によりネジ部材３５と支持本体２４との間に隙間ができたとしても再度調整することができる。この場合、防水扉３を起立位置Ｂとして座金３７の舌３７ａをナット３６の外面から離れるように折り曲げてナット３６を緩め、防水扉３が倒伏位置Ａに位置する状態で再度ネジ部材３５を防水扉３の上面から回動することでネジ部材３５を支持本体２４に当接できる。そして、前記と同様にナット３６を締め付けた後に座金３７の舌３７ａを折り曲げてネジ部材３５が緩まないようする。調整後は、再び操作孔２８にボルト３１を螺合し、操作孔２８を水密にする。 Then, the tool is inserted from above the operation hole 28. The tool is, for example, a wrench. When the screw member 35 is rotated by the tool, the screw member 35 extends downward from the waterproof door 3, and the tip of the screw member 35 is brought into contact with the upper surface of the support body 24. Then, the screw member 35 is further rotated to make the upper surface of the waterproof door 3 and the floor surface F substantially the same surface. At this time, since the adjustment work for bringing the waterproof door 3 into contact with the housing recess body 2 can be performed in the state where the waterproof door 3 is set to the lying position A, the adjustment work is facilitated and can be performed in a short time. Moreover, since the adjustment operation of the clearance gap between the waterproof door 3 and the accommodation recessed part 2 is possible by operating the screw member 35 and contact | abutting to the support main body 24, clearance gap adjustment can be performed accurately. Next, in this state, the waterproof door 3 is set to the standing position B, and the nut 36 is tightened to lock the screw member 35. Then, the tongue 37a of the washer 37 is bent so as to be adjacent to the outer surface of the nut 36 so that the nut 36 is not loosened. After that, the waterproof door 3 is again set to the fall position A, and the bolt 31 and the packing member 32 are attached to the operation hole 28 to make it watertight. At the time of this adjustment, the movement of the waterproof door 3 between the lying position A and the standing position B is only required once. Further, even if a gap is formed between the screw member 35 and the support body 24 due to long-term use, it can be adjusted again. In this case, the tongue 37a of the washer 37 is bent away from the outer surface of the nut 36 with the waterproof door 3 in the standing position B, the nut 36 is loosened, and the screw member 35 is waterproofed again in a state where the waterproof door 3 is in the lying position A. The screw member 35 can be brought into contact with the support body 24 by rotating from the upper surface of the door 3. Then, after tightening the nut 36 in the same manner as described above, the tongue 37a of the washer 37 is bent so that the screw member 35 is not loosened. After the adjustment, the bolt 31 is screwed into the operation hole 28 again to make the operation hole 28 watertight.

以上より、防水扉３の上面を床面Ｆと略同一面とすることができるので、防水扉３と床面Ｆとに段差をなくすことができて自動車等が通過したときに防水扉３の一部に荷重が集中することがない。また、昇降当接部２７が支持本体２４に当接して防水扉３と収納凹部体２との間に隙間ができないので、大型車両が防水扉３の上面を通過しても、従来のような隙間のためのガタツキが防止され部品の緩みを引き起こす有害な振動を発生させるという問題がなくなる。また、前記支持装置２３を多数配置することにより、耐荷重を増すことが可能となる。したがって、防水扉３のリブ２２を太くする必要や多数設ける必要が無くなり構造簡易で軽量にすることができ、防水扉３をより少ない力で操作することができる。尚、当該形態は、上記の例に限定されない。防水扉の下面に支持本体を設け、収納凹部体に調整機構を設けても良い。防水扉に設けた支持本体に工具を通す操作孔を設ける。その操作孔は、調整機構に備えられたネジ部材の直径より小さく工具を操作可能な直径に形成されている。調整する場合には、前記と同様に防水扉を倒伏位置とした状態で操作孔から栓部材を取外し、操作孔から工具を挿通してネジ部材を回動し、ネジ部材の上端を防水扉に設けた支持本体の下面に当接して防水扉と収納凹部体間の隙間を無くし、防水扉の上面と床面とを略同一面とすることができる。 As described above, since the upper surface of the waterproof door 3 can be made substantially flush with the floor surface F, the level difference between the waterproof door 3 and the floor surface F can be eliminated, and when the automobile or the like passes, The load does not concentrate on some parts. Further, since the elevating contact portion 27 contacts the support main body 24 and there is no gap between the waterproof door 3 and the housing recess 2, even if a large vehicle passes through the upper surface of the waterproof door 3, The problem of rattling due to gaps and the generation of harmful vibrations that cause loosening of parts is eliminated. In addition, the load resistance can be increased by arranging a large number of the support devices 23. Therefore, it is not necessary to make the ribs 22 of the waterproof door 3 thick or to provide a large number of them, the structure can be simplified and the weight can be reduced, and the waterproof door 3 can be operated with less force. In addition, the said form is not limited to said example. A support body may be provided on the lower surface of the waterproof door, and an adjustment mechanism may be provided in the storage recess. An operation hole through which the tool passes is provided in the support body provided in the waterproof door. The operation hole is formed to have a diameter smaller than the diameter of the screw member provided in the adjustment mechanism and capable of operating the tool. When adjusting, remove the plug member from the operation hole with the waterproof door in the fall position as described above, insert the tool through the operation hole, rotate the screw member, and attach the upper end of the screw member to the waterproof door. The clearance between the waterproof door and the housing recess can be eliminated by abutting against the lower surface of the provided support body, and the upper surface and the floor surface of the waterproof door can be made substantially flush with each other.
