The rigid member 32 is fixed. In order to adopt such a fixing method, in this embodiment, it is permitted to arrange the fastener 33 at an arbitrary position within the range of the elongated hole 32a. Further, a bent portion 32b is formed on one end side of the high-rigidity member 32, and the bent portion 32b has a structure that overlaps with the low-rigidity member 31.
なお、高剛性部材３２は、固定具２と昇降路壁５の間に比較的大きな間隙が存在し、片持ち状態の高剛性部材３２に乗り込み時の荷重がかかったとしても、高剛性部材３２の一端側が撓むことのない曲げ強度を確保できるように、鋼板などの高剛性の板材で形成されるのが好ましいが、要求される曲げ強度に応じてその素材や厚さを変更して良いことは言うまでもない。また、図２では、低剛性部材３１の板厚よりも高剛性部材３２の板厚を厚くしているが、剛性の大小が上述の関係にあれば、板厚の大小は図示する関係でなくても良い。
The high-rigidity member 32 has a relatively large gap between the fixture 2 and the hoistway wall 5, and even if a load is applied to the cantilevered high-rigidity member 32 when riding on the high-rigidity member 32, the high-rigidity member 32 It is preferably formed of a high-rigidity plate material such as a steel plate so that one end side of the surface can be secured without bending, but the material and thickness may be changed according to the required bending strength. Needless to say. Further, in FIG. 2, the plate thickness of the high-rigidity member 32 is made thicker than the plate thickness of the low-rigidity member 31, but if the magnitude of the rigidity has the above-mentioned relationship, the magnitude of the plate thickness is not shown. You may.
次に、図３を用いて、仕切板３の設置作業の手順を説明する。
Next, the procedure for installing the partition plate 3 will be described with reference to FIG.
まず、図３（ａ）に示すように、高剛性部材３２を昇降路壁５の上面に載置し、この状態で長孔３２ａに規制される範囲内で、高剛性部材３２を昇降路２１の奥行方向に移動させ、高剛性部材３２の奥行方向の位置を調整する。このとき高剛性部材３２の曲げ部３２ｂを昇降路壁５に固定された固定具２の側面に密着させる。これらの調整の完了後、締結具３３により高剛性部材３２を締結固定する。
First, as shown in FIG. 3A, the high-rigidity member 32 is placed on the upper surface of the hoistway wall 5, and in this state, the high-rigidity member 32 is placed in the hoistway 21 within the range regulated by the elongated hole 32a. The position of the high-rigidity member 32 in the depth direction is adjusted by moving the member in the depth direction. At this time, the bent portion 32b of the high-rigidity member 32 is brought into close contact with the side surface of the fixture 2 fixed to the hoistway wall 5. After the completion of these adjustments, the high-rigidity member 32 is fastened and fixed by the fastener 33.
次いで、図３（ｂ）に示すように、平板状の低剛性部材３１の一端側を固定具２の上面に載置した後、低剛性部材３１の上面に乗場敷居１を配置し、締結具６により乗場敷居１と固定具２で低剛性部材３１を挟み込むように共締め固定する。なお、このとき低剛性部材３１の一端側が乗場敷居１の側面より昇降路２１側に出張り、低剛性部材３１と乗りかご１１が接触することがないようにする。
Next, as shown in FIG. 3B, one end side of the flat plate-shaped low-rigidity member 31 is placed on the upper surface of the fixture 2, and then the landing sill 1 is arranged on the upper surface of the low-rigidity member 31, and the fastener is fastened. The low-rigidity member 31 is sandwiched and fixed together by the landing threshold 1 and the fixture 2 according to 6. At this time, one end side of the low-rigidity member 31 protrudes from the side surface of the landing threshold 1 toward the hoistway 21 side so that the low-rigidity member 31 and the car 11 do not come into contact with each other.
この後、図３（ｃ）に示すように、作業者は低剛性部材３１を折り曲げる。図３に例示するものは、床仕上げの厚さ寸法、つまりモルタル７の厚さ寸法Ｔ１が比較的小さいことから、低剛性部材３１と高剛性部材３２の重なり代が大きいので、作業者は低剛性部材３１を断面略クランク状に折り曲げることができる。すなわち、図３の低剛性部材３１には、高剛性部材３２の曲げ部３２ｂの上方に第１折り曲げ部３１ａが形成され、曲げ部３２ｂの下端に沿うように第２折り曲げ部３１ｂが形成される。
After that, as shown in FIG. 3C, the operator bends the low-rigidity member 31. In the example shown in FIG. 3, since the thickness dimension of the floor finish, that is, the thickness dimension T 1 of the mortar 7 is relatively small, the overlap margin between the low-rigidity member 31 and the high-rigidity member 32 is large. The low-rigidity member 31 can be bent into a substantially crank shape in cross section. That is, in the low-rigidity member 31 of FIG. 3, the first bent portion 31a is formed above the bent portion 32b of the high-rigidity member 32, and the second bent portion 31b is formed along the lower end of the bent portion 32b. ..
このようにして、乗場敷居１と昇降路壁５の間隙を塞ぐ仕切板３を設置した後、適量のモルタル７を流し込むことで、図２に示す乗場敷居装置Ａを完成させることができる。
In this way, after installing the partition plate 3 that closes the gap between the landing threshold 1 and the hoistway wall 5, the landing threshold device A shown in FIG. 2 can be completed by pouring an appropriate amount of mortar 7.
ここで、床仕上げの厚さ寸法が大きい場合の仕切板３の態様について、図４を用いて説明する。
Here, the mode of the partition plate 3 when the thickness dimension of the floor finish is large will be described with reference to FIG.
図４では、床仕上げの厚さ寸法、つまりモルタル７の厚さ寸法Ｔ２が比較的大きいことから、低剛性部材３１と高剛性部材３２の重なり代は小さく、低剛性部材３１に上述した第２折り曲げ部３１ｂを形成することができないため、低剛性部材３１は第１折り曲げ部３１ａのみが形成された、略Ｌ字状の断面形状となる。そして、低剛性部材３１の他端部を高剛性部材３２の曲げ部３２ｂと重なり合った状態とすることで、乗場敷居１と昇降路壁５の間隙を塞ぐ。このようにして仕切板３を据え付けた後、適量のモルタル７を流し込むことで、床仕上げの厚さ寸法が大きい場合であっても、適切な乗場敷居装置Ａを完成させることができる。
In FIG. 4, since the thickness dimension of the floor finish, that is, the thickness dimension T 2 of the mortar 7 is relatively large, the overlap margin between the low-rigidity member 31 and the high-rigidity member 32 is small, and the low-rigidity member 31 is described above. Since the two bent portions 31b cannot be formed, the low-rigidity member 31 has a substantially L-shaped cross-sectional shape in which only the first bent portion 31a is formed. Then, by setting the other end of the low-rigidity member 31 so as to overlap the bent portion 32b of the high-rigidity member 32, the gap between the landing threshold 1 and the hoistway wall 5 is closed. By pouring an appropriate amount of mortar 7 after installing the partition plate 3 in this way, an appropriate landing sill device A can be completed even when the floor finish has a large thickness.
以上説明したように本実施例の乗場敷居装置は、乗場開口の下縁に沿って配置され乗場ドア４の開閉動作を案内する乗場敷居１と、乗場敷居１が取り付けられる固定具２と、乗場敷居１と昇降路壁５の間の間隙を塞ぐことによって、乗場床の仕上げに用いられるモルタルが間隙から昇降路２１内に流入するのを阻止する仕切板３とを備え、仕切板３は、現地で折り曲げ可能な曲げ強度を有し、一端側が乗場敷居１と固定具２に挟まれるとともに、他端側が昇降路壁５側に延在する低剛性部材３１と、低剛性部材３１より高い所定の曲げ強度を有し、一端側が低剛性部材３１の他端側と重なり合うとともに、他端側が昇降路壁５の上面に固定される高剛性部材３２とからなる構成とした。
As described above, the landing sill device of the present embodiment is arranged along the lower edge of the landing opening to guide the opening / closing operation of the landing door 4, the landing sill 1, the fixture 2 to which the landing sill 1 is attached, and the landing. The partition plate 3 is provided with a partition plate 3 that prevents mortar used for finishing the landing floor from flowing into the hoistway 21 from the gap by closing the gap between the threshold 1 and the hoistway wall 5. A low-rigidity member 31 that has bending strength that allows it to be bent locally, one end of which is sandwiched between the landing sill 1 and the fixture 2, and the other end of which extends to the hoistway wall 5, and a predetermined value higher than that of the low-rigidity member 31. The configuration is such that one end side overlaps with the other end side of the low rigidity member 31 and the other end side is a high rigidity member 32 fixed to the upper surface of the hoistway wall 5.
このような構成によれば、仕切板３を低剛性部材３１と高剛性部材３２の分割構造とし、低剛性部材３１と高剛性部材３２の重なり代で高さ方向および昇降路２１の奥行き方向の調整を可能とすることで、高さ方向および昇降路２１の奥行き方向の建屋の寸法誤差が比較的大きい場合にも容易に対応することができるとともに、仕切板３が乗場敷居１の側面から昇降路２１側に出張ることを防ぐことができる。また、低剛性部材３１は現地で折り曲げ可能な曲げ強度のものであることから、特別な機器を要することなく所定形状に折り曲げて仕切板３の設置を行うことができる。
According to such a configuration, the partition plate 3 has a divided structure of the low-rigidity member 31 and the high-rigidity member 32, and the overlap margin of the low-rigidity member 31 and the high-rigidity member 32 is in the height direction and the depth direction of the hoistway 21. By making it possible to adjust, it is possible to easily cope with the case where the dimensional error of the building in the height direction and the depth direction of the hoistway 21 is relatively large, and the partition plate 3 moves up and down from the side surface of the landing threshold 1. It is possible to prevent a business trip to the road 21 side. Further, since the low-rigidity member 31 has a bending strength that allows it to be bent locally, the partition plate 3 can be installed by bending it into a predetermined shape without requiring special equipment.
また、本実施例の乗場敷居装置は上述の構成に加えて、高剛性部材３２は、締結具３３により昇降路壁５の上面に固定されるとともに、高剛性部材３２には、締結具３３の高剛性部材３２に対する昇降路２１の奥行き方向の位置変更を許容する長孔３２ａが形成される構成とした。
Further, in the landing sill device of the present embodiment, in addition to the above-described configuration, the high-rigidity member 32 is fixed to the upper surface of the hoistway wall 5 by the fastener 33, and the high-rigidity member 32 has the fastener 33. An elongated hole 32a that allows the position of the hoistway 21 to be changed in the depth direction with respect to the high-rigidity member 32 is formed.
このような構成によれば、昇降路２１の奥行き方向の寸法誤差が大きい場合も容易に対応することができる。
According to such a configuration, even when the dimensional error in the depth direction of the hoistway 21 is large, it can be easily dealt with.
次に、図５を用いて、本発明の実施例２に係る、エレベータの乗場敷居装置Ａを説明する。なお、実施例１との共通点は重複説明を省略する。
Next, the elevator landing threshold device A according to the second embodiment of the present invention will be described with reference to FIG. It should be noted that the common points with the first embodiment will be omitted.
実施例１では、床仕上げの厚さ寸法（モルタル７の厚さ寸法Ｔ１、Ｔ２）が比較的厚かったため、図２～図４のように、高剛性部材３２の曲げ部３２ｂを上向きにした状態で仕切板３を構成することができた。しかし、床仕上げの厚さ寸法（モルタル７の厚さ寸法）が薄くなると、曲げ部３２ｂの上端が固定具２の上面よりも高くなり、低剛性部材３１を設置できなくなる惧れがある。
In the first embodiment, since the floor finishing thickness dimensions (thickness dimensions T 1 and T 2 of the mortar 7) were relatively thick, the bent portion 32b of the high-rigidity member 32 was turned upward as shown in FIGS. 2 to 4. The partition plate 3 could be configured in this state. However, if the thickness dimension of the floor finish (thickness dimension of the mortar 7) becomes thin, the upper end of the bent portion 32b becomes higher than the upper surface of the fixture 2, and there is a possibility that the low-rigidity member 31 cannot be installed.
そこで、図５に示す本実施例のエレベータの乗場敷居装置Ａでは、床仕上げの厚さ寸法（モルタル７の厚さ寸法Ｔ３）が所定未満である場合、高剛性部材３２の曲げ部３２ｂを下向きに配置した。これにより、モルタル７の厚さ寸法Ｔ３が小さい場合であっても、乗場敷居１と昇降路壁５の間隙を塞ぐ仕切板３を形成することができる。
Therefore, in the elevator landing sill device A of the present embodiment shown in FIG. 5, when the floor finishing thickness dimension (thickness dimension T 3 of the mortar 7) is less than a predetermined value, the bent portion 32b of the high-rigidity member 32 is formed. Arranged downward. Thus, even when the thickness T 3 of the mortar 7 is small, it is possible to form the partition plate 3 which closes the gap between the landing sill 1 and the hoistway wall 5.
尚、本発明は、上述した実施例に限定するものではなく、様々な変形例が含まれる。例えば、上述した実施例は本発明を分かり易く説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定するものではない。またある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施例の構成に他の実施例の構成を加えることも可能である。また、各実施例の構成の一部について、他の構成の追加、削除、置換をすることが可能である。
