Description

本願は、起伏ゲートに関する。 The present application relates to undulating gates.

従来より、洪水や津波による浸水を防止するための起伏ゲートが知られている。例えば特許文献１に開示の起伏ゲートは、浸水時に水の浮力によって起立する扉体を備えている。そして、起立時の扉体の高さは、想定される水位よりも高くなるように設計されている。つまり、この起伏ゲートでは、扉体の両側部および底部の３方に水密ゴムを設ける方式（３方水密方式）が採用されている。 Conventionally, undulating gates for preventing inundation due to floods and tsunamis have been known. For example, the undulating gate disclosed in Patent Document 1 includes a door body that stands up by the buoyancy of water when flooded. The height of the door body when standing up is designed to be higher than the assumed water level. That is, in this undulating gate, a method (three-way watertight method) in which watertight rubber is provided on both sides and the bottom of the door body is adopted.

特開２０１２－２４１４４９号公報Japanese Unexamined Patent Publication No. 2012-241449

一方、地域によっては、大津波を想定した防潮堤の建設が計画されている。このような防潮堤を建設した場合、防潮堤の内外を行き来したいという要望がある。このような要望に対し、防潮堤の一部に車両等が通行可能な開口部を設け、その開口部に起伏ゲートを設置することが考えられる。その場合、水密構造として、扉体の両側部、底部および上部の４方を水密する方式（４方水密方式）を採用する必要がある。しかしながら、倒伏時には扉体の上面を車両が通行するような起伏ゲートにおいては、扉体の上部に水密ゴムを設けると、車両の通行によって扉体上部の水密ゴムが損傷する虞がある。 On the other hand, depending on the area, construction of a seawall is planned in anticipation of a large tsunami. When such a seawall is constructed, there is a desire to go back and forth inside and outside the seawall. In response to such a request, it is conceivable to provide an opening through which vehicles and the like can pass in a part of the seawall, and to install an undulating gate in the opening. In that case, as a watertight structure, it is necessary to adopt a method (four-way watertight method) in which both sides, the bottom and the upper part of the door body are watertight. However, in an undulating gate where a vehicle passes through the upper surface of the door body when lying down, if a watertight rubber is provided on the upper part of the door body, the watertight rubber on the upper part of the door body may be damaged by the passage of the vehicle.

本願に開示の技術は、かかる事情に鑑みてなされたものであり、その目的は、倒伏時に車両等の通行に起因する上部水密ゴムの損傷を防止しつつ、扉体の上部水密を確保することができる起伏ゲートを提供することにある。 The technique disclosed in the present application has been made in view of such circumstances, and the purpose thereof is to secure the upper watertightness of the door body while preventing damage to the upper watertight rubber due to the passage of vehicles or the like when lying down. The purpose is to provide an undulating gate that can be used.

本願の起伏ゲートは、扉体と、側部戸当りおよび上部戸当りと、側部水密ゴムと、上部水密ゴムとを備えている。前記扉体は、基端側を中心に回動して起立するものである。前記側部水密ゴムは、前記扉体の幅方向両端部に取り付けられ、前記側部戸当りと接するものである。前記上部水密ゴムは、前記上部戸当りに取り付けられ、前記扉体が起立した際に、前記扉体の倒伏時の上面と同じ平面上に位置する前記扉体の先端が接するものである。 The undulating gate of the present application includes a door body, a side door stop and an upper door stop, a side watertight rubber, and an upper watertight rubber. The door body rotates around the base end side and stands up. The side watertight rubber is attached to both ends in the width direction of the door body and is in contact with the side door contact. The upper watertight rubber is attached to the upper door contact, and when the door body stands up, the tip of the door body located on the same plane as the upper surface of the door body when the door body is laid down is in contact with the upper watertight rubber.

そして、前記側部水密ゴムは、前記扉体の先端の位置まで取り付けられると共に、前記扉体の先端側の端部が、前記上面と面一となるように取り付けられている。前記上部水密ゴムの前記扉体の幅方向における両端部は、前記扉体が起立した際に、前記側部水密ゴムにおける前記扉体の先端側の端部と接するように構成されている。 The side watertight rubber is attached to the position of the tip of the door body, and the end of the door body on the tip end side is attached so as to be flush with the upper surface. Both ends of the upper watertight rubber in the width direction of the door body are configured to be in contact with the end portions of the side watertight rubber on the tip end side of the door body when the door body stands up.

本願の起伏ゲートによれば、倒伏時に車両等の通行に起因する上部水密ゴムの損傷を防止しつつ、扉体の上部水密を確保することができる。 According to the undulating gate of the present application, it is possible to secure the upper watertightness of the door body while preventing damage to the upper watertight rubber due to the passage of a vehicle or the like at the time of lodging.

以下、本願の実施形態について図面を参照しながら説明する。なお、以下の実施形態は、本質的に好ましい例示であって、本願に開示の技術、その適用物、あるいはその用途の範囲を制限することを意図するものではない。 Hereinafter, embodiments of the present application will be described with reference to the drawings. It should be noted that the following embodiments are essentially preferred examples and are not intended to limit the scope of the techniques disclosed in this application, their applications, or their uses.

本実施形態の起伏ゲート１は、例えば防潮堤に設けられたトンネル状の開口部の路面Ｒに設置され、津波による水の浸入を防止するものである。上記開口部は、略矩形に形成され、防潮堤の内外を車両等が行き来するためのものである。起伏ゲート１は、浸入しようとする水を利用して自動的に起立動作および倒伏動作を行う、浮体式の起伏ゲートである。 The undulating gate 1 of the present embodiment is installed on the road surface R of a tunnel-shaped opening provided in a seawall, for example, to prevent water from entering due to a tsunami. The opening is formed in a substantially rectangular shape, and is for vehicles and the like to move in and out of the seawall. The undulating gate 1 is a floating undulating gate that automatically performs an upright operation and an undulating operation by using water to be infiltrated.

図１および図２に示すように、起伏ゲート１は、扉体１０と、戸当り（側部戸当り２１、上部戸当り２２）と、格納部２３と、水密ゴム（側部水密ゴム３０、底部水密ゴム（図示省略）、上部水密ゴム４０）とを備えている。なお、図２において水は右側から浸入するものとする。また、以降で記載する「上流側」および「下流側」とは、水の浸入方向における上流側（図２において右側）および下流側（図２において左側）を意図する。 As shown in FIGS. 1 and 2, the undulating gate 1 includes a door body 10, a door stop (21 side door stop, 22 upper door stop), a storage portion 23, and a watertight rubber (side watertight rubber 30, 30). It is provided with a bottom watertight rubber (not shown) and a top watertight rubber 40). In addition, in FIG. 2, it is assumed that water infiltrates from the right side. Further, the "upstream side" and "downstream side" described below are intended to be the upstream side (right side in FIG. 2) and the downstream side (left side in FIG. 2) in the water infiltration direction.

扉体１０は、やや扁平な略矩形体に形成されており、基端側を中心に回動して起立する。具体的に、扉体１０は、基端側に回動軸１３を有しており、回動軸１３を中心として回動自在に設けられている。扉体１０は、図２において左回りに回動することで起立動作を行い、図２において右回りに回動することで倒伏動作を行う。扉体１０は、通常時は倒伏した状態（図１に示す状態）になっており、非常時（即ち、水が浸入してきたとき）には浸入水の浮力によって倒伏状態から回動し起立するように構成されている。つまり、扉体１０は浸入水を利用して起立動作を開始する。 The door body 10 is formed in a slightly flat and substantially rectangular body, and rotates around the proximal end side to stand up. Specifically, the door body 10 has a rotation shaft 13 on the base end side, and is rotatably provided around the rotation shaft 13. The door body 10 performs an upright operation by rotating counterclockwise in FIG. 2, and performs a lodging operation by rotating clockwise in FIG. 2. The door body 10 is normally in an inverted state (the state shown in FIG. 1), and in an emergency (that is, when water infiltrates), the door body 10 rotates from the inverted state due to the buoyancy of the infiltrated water and stands up. It is configured as follows. That is, the door body 10 starts the standing operation by using the infiltrated water.

格納部２３は、路面Ｒに凹状に形成されている。格納部２３は、平面視で扉体１０よりも大きい矩形に形成されており、倒伏した扉体１０が格納される。扉体１０が格納部２３に格納された状態、即ち扉体１０が倒伏した状態では、扉体１０（本体１１）の上面１１と路面Ｒとが略面一となる。また、扉体１０は、基端側が下流側に位置し先端１４が上流側に位置した状態で格納される。通常時は、路面Ｒを通行する車両や人は扉体１０の上面１１を通行することになる。本願の請求項に係る「扉体の上面」とは、倒伏時（倒伏状態）の扉体１０の上面１１を意図する。扉体１０の上面１１は、略平坦な面である。 The storage portion 23 is formed in a concave shape on the road surface R. The storage unit 23 is formed in a rectangular shape larger than the door body 10 in a plan view, and the collapsed door body 10 is stored. When the door body 10 is stored in the storage unit 23, that is, when the door body 10 is laid down, the upper surface 11 of the door body 10 (main body 11) and the road surface R are substantially flush with each other. Further, the door body 10 is stored in a state where the base end side is located on the downstream side and the tip end 14 is located on the upstream side. Normally, a vehicle or a person passing through the road surface R will pass through the upper surface 11 of the door body 10. The "upper surface of the door body" according to the claim of the present application is intended to be the upper surface 11 of the door body 10 at the time of lying down (downturned state). The upper surface 11 of the door body 10 is a substantially flat surface.

側部戸当り２１は、扉体１０の両側方、即ち上述した開口部の左右の側壁に設けられている。上部戸当り２２は、扉体１０の上方、即ち開口部の天井壁に設けられている。側部戸当り２１は鉛直方向に延びており、上部戸当り２２は水平方向（即ち、図１における左右方向、扉体１０の幅方向）に延びている。 The side door stops 21 are provided on both sides of the door body 10, that is, on the left and right side walls of the above-mentioned opening. The upper door stop 22 is provided above the door body 10, that is, on the ceiling wall of the opening. The side door stop 21 extends in the vertical direction, and the upper door stop 22 extends in the horizontal direction (that is, the left-right direction in FIG. 1, the width direction of the door body 10).

水密ゴム（側部水密ゴム３０、底部水密ゴム３８、上部水密ゴム４０）は、扉体１０と戸当りとの間を水密する。 The watertight rubber (side watertight rubber 30, bottom watertight rubber 38, upper watertight rubber 40) is watertight between the door body 10 and the door stop.

図３および図４にも示すように、側部水密ゴム３０は、扉体１０の倒伏時の上面１１における扉体１０の幅方向両端部に取り付けられている。側部水密ゴム３０は、扉体１０の上面１１において幅方向と直交する方向（以下、高さ方向とも言う。）における略全域に取り付けられている。つまり、側部水密ゴム３０は、扉体１０の基端側から先端１４の位置まで取り付けられている。側部水密ゴム３０は、上から押さえ板３５によって扉体１０の上面１１に押し付けられている。側部水密ゴム３０は、扉体１０の幅方向両端から突出して設けられ、側部戸当り２１と接する（図５等参照）。 As shown in FIGS. 3 and 4, the side watertight rubber 30 is attached to both ends of the door body 10 in the width direction on the upper surface 11 when the door body 10 is laid down. The side watertight rubber 30 is attached to substantially the entire area of the upper surface 11 of the door body 10 in a direction orthogonal to the width direction (hereinafter, also referred to as a height direction). That is, the side watertight rubber 30 is attached from the base end side of the door body 10 to the position of the tip 14. The side watertight rubber 30 is pressed from above against the upper surface 11 of the door body 10 by the pressing plate 35. The side watertight rubber 30 is provided so as to project from both ends in the width direction of the door body 10 and is in contact with the side door contact 21 (see FIG. 5 and the like).

側部水密ゴム３０は、扉体１０の高さ方向の位置によって、断面形状（扉体１０の幅方向に切断した断面形状）が異なる。さらに、側部水密ゴム３０は、扉体１０の高さ方向における扉体１０の先端１４側の端部が、扉体１０の上面１１と面一となるように取り付けられている。 The cross-sectional shape (cross-sectional shape cut in the width direction of the door body 10) of the side watertight rubber 30 differs depending on the position in the height direction of the door body 10. Further, the side watertight rubber 30 is attached so that the end portion of the door body 10 on the tip 14 side in the height direction of the door body 10 is flush with the upper surface 11 of the door body 10.

具体的に、側部水密ゴム３０は、湾曲部３２と平部３３からなっている。なお、湾曲部３２および平部３３は互いに連続して形成されている。側部水密ゴム３０は、扉体１０の高さ方向において５つの区間Ｗ１～Ｗ５に区分される。湾曲部３２は区間Ｗ１～Ｗ４に位置し、平部３３は区間Ｗ５に位置している。なお、ここでは、側部水密ゴム３０のうち基端側に位置する底部水密ゴムとの取り合い部分については説明を省略する。 Specifically, the side watertight rubber 30 is composed of a curved portion 32 and a flat portion 33. The curved portion 32 and the flat portion 33 are continuously formed. The side watertight rubber 30 is divided into five sections W1 to W5 in the height direction of the door body 10. The curved portion 32 is located in the sections W1 to W4, and the flat portion 33 is located in the section W5. Here, the description of the portion of the side watertight rubber 30 that is connected to the bottom watertight rubber located on the base end side will be omitted.

平部３３は、断面形状が厚さ一定の平板状に形成されている（図７参照）。ただし、平部３３は、側部戸当り２１と接する先端が凸型の円弧状に形成されている。湾曲部３２は、側部戸当り２１と接する先端部が湾曲している（図５等参照）。湾曲部３２は、外見上、板状部材を折り曲げたような形状となっており、例えば型枠成形によって製作される。 The flat portion 33 is formed in a flat plate shape having a constant cross-sectional shape (see FIG. 7). However, the flat portion 33 is formed in a convex arc shape at the tip in contact with the side door stop 21. The curved portion 32 has a curved tip portion in contact with the side door stop 21 (see FIG. 5 and the like). The curved portion 32 is apparently shaped like a bent plate-shaped member, and is manufactured by, for example, formwork forming.

図５に示すように、区間Ｗ１では、扉体１０の上面１１に、順に、湾曲部３２（側部水密ゴム３０）および押さえ板３５が設けられている。そして、湾曲部３２は側部戸当り２１と接するようになっている。図６～図８に示すように、区間Ｗ３～Ｗ５では、扉体１０の上面１１における扉体１０の幅方向両端部に凹んだ段差部１５が設けられている。つまり、扉体１０の上面１１において側部水密ゴム３０が取り付けられる部分が凹んでいる。区間Ｗ３～Ｗ５では、段差部１５の深さは一定である。なお、区間Ｗ２は、扉体１０の先端１４側へいくに従って段差部１５の深さが大きくなる区間である。 As shown in FIG. 5, in the section W1, curved portions 32 (side watertight rubber 30) and holding plates 35 are sequentially provided on the upper surface 11 of the door body 10. The curved portion 32 is in contact with the side door stop 21. As shown in FIGS. 6 to 8, in the sections W3 to W5, recessed step portions 15 are provided at both ends of the door body 10 in the width direction on the upper surface 11 of the door body 10. That is, the portion of the upper surface 11 of the door body 10 to which the side watertight rubber 30 is attached is recessed. In the sections W3 to W5, the depth of the step portion 15 is constant. The section W2 is a section in which the depth of the step portion 15 increases toward the tip 14 side of the door body 10.

図６に示すように、区間Ｗ３では、扉体１０の段差部１５に湾曲部３２（側部水密ゴム３０）が取り付けられ、その上に押さえ板３５が設けられている。湾曲部３２は、段差部１５に取り付けられた部分が扉体１０の上面１１と面一となっている。区間Ｗ４の湾曲部３２では、先端部の大きさが、扉体１０の先端１４側にいくに従って小さくなり、平部３３と繋がる。 As shown in FIG. 6, in the section W3, the curved portion 32 (side watertight rubber 30) is attached to the stepped portion 15 of the door body 10, and the holding plate 35 is provided on the curved portion 32. In the curved portion 32, the portion attached to the step portion 15 is flush with the upper surface 11 of the door body 10. In the curved portion 32 of the section W4, the size of the tip portion decreases toward the tip 14 side of the door body 10 and is connected to the flat portion 33.

図７および図８に示すように、区間Ｗ５では、扉体１０の段差部１５に平部３３（側部水密ゴム３０）が取り付けられ、その上に押さえ板３５が設けられている。平部３３は、上面が扉体１０の上面１１と面一となっている。こうして、側部水密ゴム３０における扉体１０の先端１４側の端部（平部３３）が、扉体１０の上面１１と面一となるように取り付けられる。また、側部水密ゴム３０は、扉体１０の先端１４側の端部（平部３３）以外の少なくとも一部が、扉体１０の上面１１に取り付けられる。 As shown in FIGS. 7 and 8, in the section W5, the flat portion 33 (side watertight rubber 30) is attached to the stepped portion 15 of the door body 10, and the holding plate 35 is provided on the flat portion 33. The upper surface of the flat portion 33 is flush with the upper surface 11 of the door body 10. In this way, the end portion (flat portion 33) of the side watertight rubber 30 on the tip 14 side of the door body 10 is attached so as to be flush with the upper surface 11 of the door body 10. Further, at least a part of the side watertight rubber 30 other than the end portion (flat portion 33) on the tip 14 side of the door body 10 is attached to the upper surface 11 of the door body 10.

上部水密ゴム４０は、上部戸当り２２の下面に取り付けられており、扉体１０の幅方向に延びている。上部水密ゴム４０は、扉体１０の幅方向における両端部がゴム接触部４２となっており、その間の部分が扉体接触部４１となっている。 The upper watertight rubber 40 is attached to the lower surface of the upper door stop 22 and extends in the width direction of the door body 10. In the upper watertight rubber 40, both ends of the door body 10 in the width direction are rubber contact portions 42, and the portions between them are door body contact portions 41.

図９～図１１に示すように、扉体接触部４１は、凸型に形成されており、上下流方向両側が押さえ板４５，４６によって固定されている。扉体接触部４１は、扉体１０が起立した際に、扉体１０の先端１４が接する部分である。扉体１０の先端１４は、扉体１０の上面１１と同じ平面上に位置している。ゴム接触部４２は、扉体１０が起立した際に、側部水密ゴム３０における扉体１０の先端１４側の端部３４（平部３３の端部３４）と接する部分である。 As shown in FIGS. 9 to 11, the door body contact portion 41 is formed in a convex shape, and both sides in the upstream and downstream directions are fixed by holding plates 45 and 46. The door body contact portion 41 is a portion where the tip 14 of the door body 10 comes into contact with the door body 10 when the door body 10 stands up.
