Description

本発明は、鋼製扉及び鋼製扉の製造方法に関するものである。 The present invention relates to a steel door and a method for manufacturing a steel door.

鋼製扉は、扉フレームに対して第1表面材及び第2表面材を固定することで形成される。第1表面材及び第2表面材を扉フレームに固定する際には、扉フレームに対して固定される表面材同士の位置調整を行う必要がある。通常、扉フレームは扉体の高さ方向に延びる複数本の中骨を備えており、中骨と表面材との固定には熱溶融性の接着剤を用いる手法、中骨と表面材を両面テープで接着する手法(特許文献1)がある。 The steel door is formed by fixing the first surface material and the second surface material to the door frame. When fixing the first surface material and the second surface material to the door frame, it is necessary to adjust the positions of the surface materials fixed to the door frame. Usually, the door frame has a plurality of central bones that extend in the height direction of the door body. A method using a heat-meltable adhesive is used to fix the central bone and the surface material. There is a technique of adhering with a tape (Patent Document 1).

前者の場合には、鋼製扉は、いわゆるホットプレス工法によって製造される。扉フレームを挟むように第1表面材及び第2表面材を設けた状態で、ホットプレスの熱で接着剤が溶融することで流動性を呈し、第1表面材及び第2表面材の位置調整が可能である。 In the former case, the steel door is manufactured by a so-called hot press method. With the first surface material and the second surface material provided so as to sandwich the door frame, the adhesive is melted by the heat of the hot press to exhibit fluidity and adjust the position of the first surface material and the second surface material. Is possible.

後者の場合には、鋼製扉は、いわゆる溶接工法によって製造される。先ず、第1表面材に扉フレームを位置決め固定し、扉フレームが固定された第1表面材に対して第2表面材を被せて位置決めし、第2表面材を位置決めした状態で、第2表面材が第1表面材に対して回動可能なように、第2表面材を第1表面材に対して部分的(戸尻側、戸先側のいずれか一辺)に仮溶接して、仮固定する。なお、扉フレームの一部が予め第2表面材に溶接されているような場合もある。仮固定された第2表面材を第1表面材に対して回動させて、扉フレームを露出させ、中骨の両面テープの保護フィルムを剥がして、第2表面材を扉フレームに再び被せるように回動させて、第2表面材と扉フレームを接着し、第1表面材と第2表面材を戸先側、戸尻側、上部において溶接する。 In the latter case, the steel door is manufactured by a so-called welding method. First, the door frame is positioned and fixed on the first surface material, the second surface material is placed on the first surface material to which the door frame is fixed, and the second surface material is positioned. Temporarily welding the second surface material partially to the first surface material (one side of the door butt side or the door tip side) so that the material can rotate relative to the first surface material. Fix it. In some cases, a part of the door frame is previously welded to the second surface material. The temporarily fixed second surface material is rotated with respect to the first surface material, the door frame is exposed, the protective film of the double-sided tape of the middle bone is peeled off, and the second surface material is covered again on the door frame. The second surface material and the door frame are bonded to each other, and the first surface material and the second surface material are welded at the door tip side, door bottom side, and upper part.

ここで、引戸用の鋼製扉においては、第1表面材の面部の下端及び第2表面材の面部の下端には、折り返し状の掛止片が形成されており、扉フレームの下側フレームを下向きコ字状に形成し、下側フレームの下端を前記掛止片に対向させて、第1表面材、第2表面材の下端側の熱変形による開きを防止している(特許文献2の図5参照)。このような引戸用の鋼製扉を上記溶接工法で製造しようとすると、表面材の下端の掛止片が下側フレームの下端に引っ掛かってしまうため、溶接工法を採用することができない。
特許第3845821号 特開2012−92650号
Here, in the steel door for sliding doors, folded-back hook pieces are formed on the lower end of the surface portion of the first surface material and the lower end of the surface portion of the second surface material, and the lower frame of the door frame Is formed in a downward U-shape, and the lower end of the lower frame is opposed to the retaining piece to prevent the first surface material and the second surface material from opening due to thermal deformation (Patent Document 2). FIG. 5). If such a steel door for sliding doors is to be manufactured by the above-described welding method, the latching piece at the lower end of the surface material will be caught by the lower end of the lower frame, so the welding method cannot be employed.

図6、7に示すように、第1表面材7の面部70の下端側、第2表面材8の面部80の下端側は、下側フレーム3の下面部30を越えて下方に延びており、本明細書において、かかる部位を「下側部位」という。第1表面材7の面部70の下側部位700の下端には、上述した下側折り曲げ片74及び立ち上がり片75が形成されている。第2表面材8の面部80の下側部位800の下端には、上述した下側折り曲げ片84及び立ち上がり片85が形成されている。 As shown in FIGS. 6 and 7, the lower end side of the surface portion 70 of the first surface material 7 and the lower end side of the surface portion 80 of the second surface material 8 extend downward beyond the lower surface portion 30 of the lower frame 3. In this specification, such a part is referred to as a “lower part”. The lower bent piece 74 and the rising piece 75 described above are formed at the lower end of the lower portion 700 of the surface portion 70 of the first surface material 7. The lower bent piece 84 and the rising piece 85 described above are formed at the lower end of the lower portion 800 of the surface portion 80 of the second surface material 8.

下側フレーム3の下面部30には、下側部位700、800間に位置して表面材開き防止用部材9が取り付けられている。表面材開き防止用部材9は、扉体1の幅方向に水平状に延びる長尺部材であって、下側フレーム3の下面部30に沿って延びる上面部90と、扉体1の一方の見付面に沿って上面部90から垂下する第1垂下片91と、他方の見付面に沿って上面部90から垂下する第2垂下片92と、から断面視コ字状に形成されている。 A surface material opening preventing member 9 is attached to the lower surface portion 30 of the lower frame 3 so as to be positioned between the lower portions 700 and 800. The surface material opening prevention member 9 is a long member extending horizontally in the width direction of the door body 1, and includes an upper surface portion 90 extending along the lower surface portion 30 of the lower frame 3, and one of the door bodies 1. A first hanging piece 91 that hangs down from the upper surface portion 90 along the finding surface and a second hanging piece 92 that hangs down from the upper surface portion 90 along the other finding surface are formed in a U-shape in cross-sectional view. Yes.

表面材開き防止用部材9の上面部90は、下側フレーム3の下面部30に当接しており、第1垂下片91は下側部位700に近接ないし接触しており、第2垂下片92は下側部位800に近接ないし接触している。図7に示すように、第1垂下片91の下端は、立ち上がり片75の上端よりも下方の高さ位置にあり、第1垂下片91の下端側と立ち上がり片75の上端側は対向している。第2垂下片92の下端は、立ち上がり片85の上端よりも下方の高さ位置にあり、第2垂下片92の下端側と立ち上がり片85の上端側は対向している。こうすることで、第1表面材7ないし第2表面材8の下端側が熱等により変形した場合、立ち上がり片75、85が、表面材開き防止用部材9の第1垂下片91、第垂下片92の下端部位に係止することで、第1表面材7ないし第2表面材8の下端側が開くことを防止する。 The upper surface portion 90 of the surface material opening preventing member 9 is in contact with the lower surface portion 30 of the lower frame 3, and the first hanging piece 91 is close to or in contact with the lower portion 700, and the second hanging piece 92.

The lower end of the second hanging piece 92 is at a lower position than the upper end of the rising piece 85, and the lower end side of the second hanging piece 92 and the upper end side of the rising piece 85 are opposed to each other. Thus, when the lower end side of the first surface material 7 or the second surface material 8 is deformed by heat or the like, the rising pieces 75 and 85 are the first hanging piece 91 and the first hanging piece of the surface material opening prevention member 9. By engaging with the lower end portion of 92, the lower end side of the first surface material 7 or the second surface material 8 is prevented from opening.

扉体1の下端部には、さらに、下側部位700、800(表面材開き用防止部材9の第1垂下片91と第2垂下片92)間に位置して、ガイドレール10が取り付けられている。ガイドレール10は、扉体1の幅方向に水平状に延びる長尺部材であって、下側フレーム3の下面部30(表面材開き防止部材9の上面部90)に沿って延びる上面部100と、扉体1の一方の見付面に沿って上面部100から垂下する第1垂下片101と、他方の見付面に沿って上面部100から垂下する第2垂下片102と、から断面視コ字状に形成されている。なお、振れ止めローラ17の径によっては、表面材開き防止部材9がガイドレールとして機能するように設計してもよい。 A guide rail 10 is attached to the lower end portion of the door body 1 so as to be positioned between the lower portions 700 and 800 (the first hanging piece 91 and the second hanging piece 92 of the surface material opening prevention member 9). ing. The guide rail 10 is a long member that extends horizontally in the width direction of the door body 1, and the upper surface portion 100 that extends along the lower surface portion 30 (the upper surface portion 90 of the surface material opening prevention member 9) of the lower frame 3. And a first hanging piece 101 that hangs down from the upper surface portion 100 along one finding surface of the door body 1 and a second hanging piece 102 that hangs down from the upper surface portion 100 along the other finding surface. It is formed in a U-shape. Depending on the diameter of the steadying roller 17, the surface material opening preventing member 9 may be designed to function as a guide rail.

表面材開き防止部材9、ガイドレール10は、上面部90、100において、下側フレーム3の下面部30に対して、扉体1の幅方向の複数個所で螺子Sで固定されている。螺子Sは扉体1の外部から見えないので意匠を損ねることがない。また、表面材開き防止部材9の第1垂下片91、第2垂下片92は、非固定状態で下端部位700、800の内面に近接ないし接触しているだけであり、下端部位700、800に如何なる固定手段も設けていないので、下端部位700、800の外観を損ねることがない。 The surface material opening prevention member 9 and the guide rail 10 are fixed to the lower surface portion 30 of the lower frame 3 with screws S at a plurality of positions in the width direction of the door body 1 on the upper surface portions 90 and 100. Since the screw S is not visible from the outside of the door body 1, the design is not impaired. Further, the first hanging piece 91 and the second hanging piece 92 of the surface material opening preventing member 9 are only close to or in contact with the inner surfaces of the lower end portions 700 and 800 in an unfixed state. Since no fixing means is provided, the appearance of the lower end portions 700 and 800 is not impaired.

図6に示すように、第1表面材7の戸尻側折り曲げ片73及び第2表面材8の戸尻側折り曲げ片83の下端は、下側フレーム3の下面部30の直ぐ上の高さに位置しており、第1表面材7の面部70の下端部位700、第2表面材8の面部80の下端部位800までは達していない。よって、扉体1の戸尻側端面の下方には、下側部位700、800間のスペースに連通する開口が形成されている。この開口は、後述するように、表面材開き防止部材9、ガイドレール10の取り付け時に必要となる。扉体1の戸尻側が戸袋部16内に引き込まれるタイプの引戸装置では、この開口を必ずしも隠蔽する必要はないが、扉体1の戸尻側が外部に露出するようなタイプの引戸装置では、この開口を閉塞することが望ましい。なお、本実施形態では、第2表面材8の戸先側折り曲げ片82の下端は下側部位700、800に対応して第1表面材7、第2表面材8の下端まで延びているが、第2表面材8の戸先側折り曲げ片82の下方部位を切り欠いて下側部位700、800間のスペースに連通する開口を形成してもよい。 As shown in FIG. 6, the lower ends of the door butt side bent piece 73 of the first surface material 7 and the door butt side bent piece 83 of the second surface material 8 are the height immediately above the lower surface portion 30 of the lower frame 3. The lower end portion 700 of the surface portion 70 of the first surface material 7 and the lower end portion 800 of the surface portion 80 of the second surface material 8 are not reached. Therefore, an opening communicating with the space between the lower portions 700 and 800 is formed below the door end side end surface of the door body 1. As will be described later, this opening is required when the surface material opening prevention member 9 and the guide rail 10 are attached. In the sliding door device of the type in which the door butt side of the door body 1 is drawn into the door pocket portion 16, it is not always necessary to conceal this opening, but in the type of sliding door device in which the door butt side of the door body 1 is exposed to the outside, It is desirable to close this opening. In the present embodiment, the lower end of the door-side bent piece 82 of the second surface material 8 extends to the lower ends of the first surface material 7 and the second surface material 8 corresponding to the lower portions 700 and 800. Further, an opening that communicates with the space between the lower portions 700 and 800 may be formed by notching a lower portion of the door-end side bent piece 82 of the second surface material 8.
