Description

本発明は、階段の踏板や床等に手摺子を取り付ける手摺子の取付構造に関する。   The present invention relates to a handrail attachment structure for attaching a handrail to a tread or a floor of a staircase.

従来より、階段の踏板や床等に手摺を設ける場合、手摺子の根元部側面から取付面に向かって斜めにビス等を打ち込む構造が知られている。また、手摺子を取り付ける取付面の下方に設置された鉄板からビス等を螺合して、手摺子を取り付ける技術も提案されている（例えば、特許文献１参照）。
特開２００４−１６２５１８号公報 2. Description of the Related Art Conventionally, when handrails are provided on a step board or a floor of a staircase, a structure is known in which screws or the like are driven obliquely from a side surface of a root portion of a handrail toward an attachment surface. In addition, a technique for attaching a handrail by screwing a screw or the like from an iron plate installed below an attachment surface to which the handrail is attached has been proposed (for example, see Patent Document 1).
JP 2004-162518 A

しかしながら、手摺子の根元部側面から斜め下方にビス等を打ち込む構造では、ビス等の頭部が露出して美観を損なうという問題があった。また、床の下方に鉄板を設置する構造では、フローリングを張る前に手摺子を取り付ける必要があり、階段の踏板の下方に鉄板を設置する構造では、踏板に切欠を設けたり、踏板の下方からビス等を打ち込む必要があるため、両構造とも、施工が煩雑になる上に、急な設計の変更に対応できないという問題があった。   However, in the structure in which a screw or the like is driven obliquely downward from the side surface of the base portion of the handrail, there is a problem that the head of the screw or the like is exposed and the aesthetic appearance is impaired. In addition, in the structure where the iron plate is installed below the floor, it is necessary to attach a handrail before installing the flooring. In the structure where the iron plate is installed below the step board of the staircase, a notch is provided in the tread board, or from below the tread board. Since it is necessary to drive in a screw or the like, both structures have problems that the construction is complicated and that it is impossible to cope with a sudden design change.

本発明の課題は、手摺子の取付構造において、美観を損なうことなく、階段の踏板や床等を施工した後に手摺子を取り付けることである。   An object of the present invention is to attach a balustrade after constructing a stair tread or a floor without impairing the aesthetics in the balustrade attachment structure.

以上の課題を解決するため、請求項１に記載の発明は、例えば図１に示すように、階段の踏板や床等の取付面（例えば、踏板３、踊り場４）に手摺子２が取り付けられる手摺子の取付構造において、
前記手摺子２はその下端部に、下端面に開口する中空部２ａを有しており、
前記取付面（例えば、踏板３、踊り場４）には、取付金物６が取り付けられており、
前記手摺子２は、その中空部２ａに下方から前記取付金物６が嵌合されることによって、該取付金物６を介して前記取付面（例えば、踏板３、踊り場４）に取り付けられていることを特徴としている。 In order to solve the above problems, in the invention described in claim 1, as shown in FIG. 1, for example, a handrail 2 is attached to an attachment surface (for example, a tread 3, a landing 4) of a stair tread or a floor. In the mounting structure of the handrail,
The handrail 2 has a hollow portion 2a opened at the lower end surface at the lower end portion thereof,
An attachment hardware 6 is attached to the attachment surface (for example, the tread board 3 and the landing 4).
The handrail 2 is attached to the attachment surface (for example, the tread board 3 and the landing 4) via the attachment fitting 6 by fitting the attachment fitting 6 into the hollow portion 2a from below. It is characterized by.

Can do. Moreover, since the attachment metal fitting 6 is fitted into the hollow portion 2a of the handrail 2 and is not exposed, the handrail 2 can be attached without impairing the aesthetic appearance.

さらに、取付金物６と各踏板３及び踊り場４との間にプレート５が介在している。このプレート５がない場合は、手摺子２の下端面の縁部のみが各踏板３及び踊り場４に接するため、その縁部が手摺１及び手摺子２の荷重によって各踏板３及び踊り場４に食い込んで、手摺子２が傾斜して不安定となり、この場合、手摺子２の取り付けを補修する手間がかかるが、取付金物６と各踏板３及び踊り場４との間にプレート５を介在させることによって、手摺子２の下端面の縁部より、手摺１及び手摺子２の荷重をプレート５が受けることになる。このプレート５は、手摺子２の下端面の縁部に比して、各踏板３及び踊り場４に接する面積が大きいため、プレート５から各踏板３及び踊り場４に取り付けられた下地プレート９にかかる単位面積当りの荷重は小さくなる。従って、プレート５は踏板３及び踊り場４に食い込まなくなり、手摺子２を安定した状態で取り付けることができる。   Further, a plate 5 is interposed between the mounting hardware 6 and each of the treads 3 and the landing 4. Without this plate 5, only the edge of the lower end surface of the handrail 2 is in contact with each step board 3 and landing 4, so that the edge bites into each step 3 and landing 4 due to the load of the handrail 1 and handrail 2. Then, the handrail 2 is inclined and unstable, and in this case, it takes time to repair the attachment of the handrail 2, but by interposing the plate 5 between the mounting hardware 6, each step board 3, and the landing 4 The plate 5 receives the load of the handrail 1 and the handrail 2 from the edge of the lower end surface of the handrail 2. Since the plate 5 has a larger area in contact with each step board 3 and the landing 4 than the edge of the lower end surface of the handrail 2, the plate 5 covers the base plate 9 attached to each step 3 and the landing 4 from the plate 5. The load per unit area becomes smaller. Therefore, the plate 5 does not bite into the step board 3 and the landing 4 and the handrail 2 can be attached in a stable state.

また、プレート５は、手摺子２の下端面と略同じ平面形状を有するため、手摺子２の下端面と略同じ外周を有することになる。よって、プレート５は、手摺子２の下端面に過不足なく当接する。従って、手摺子２及びプレート５の外周面の境界部には不陸がなくなり、手摺子２が各踏板３及び踊り場４に直接取り付けられたような外観を呈するため、意匠的に優れた手摺子とすることができる。   Further, since the plate 5 has substantially the same planar shape as the lower end surface of the handrail 2, it has substantially the same outer periphery as the lower end surface of the handrail 2. Therefore, the plate 5 contacts the lower end surface of the handrail 2 without excess or deficiency. Therefore, the handrails 2 and the outer peripheral surface of the plate 5 are free from unevenness, and the handrails 2 have the appearance of being directly attached to the treads 3 and the landings 4. It can be.

取付金物６は、その取付部６ａが各踏板３及び踊り場４に取り付けられ、この取付部６ａの両端部には、一対の立設板部６ｂが対向して立設されている。これらの立設板部６ｂが手摺子２の中空部２ａの内壁面２ｂに当接した状態で、取付金物６が手摺子２の中空部２ａに嵌合されるため、各踏板３及び踊り場４に取り付けられた取付金物６に対して、手摺子２を所定の角度で正確に取り付けることができる。   The attachment hardware 6 has attachment portions 6a attached to the respective treads 3 and the landing 4 and a pair of upright plate portions 6b are erected on both ends of the attachment portion 6a. The mounting hardware 6 is fitted into the hollow portion 2a of the handrail 2 in a state where these standing plate portions 6b are in contact with the inner wall surface 2b of the hollow portion 2a of the handrail 2, so that each step board 3 and landing 4 The handrail 2 can be accurately attached at a predetermined angle with respect to the attachment hardware 6 attached to.

さらに、取付金物６の取付部６ａは、第１止着材７によって踏板３及び踊り場４に取り付けられ、手摺子２の下端部は、第２止着材８によって取付金物６の立設板部６ｂに取り付けられている。従って、取付部６ａを各踏板３及び踊り場４に、手摺子２を立設板部６ｂに、より強固に取り付けることができる。   Further, the attachment portion 6 a of the attachment hardware 6 is attached to the step board 3 and the landing 4 by the first fastening material 7, and the lower end portion of the handrail 2 is attached to the standing plate portion of the attachment hardware 6 by the second fastening material 8. It is attached to 6b. Therefore, the attachment portion 6a can be more firmly attached to each of the treads 3 and the landing 4 and the handrail 2 can be attached more firmly to the standing plate portion 6b.

また、踊り場４に取り付けられる下地プレート９に前もって下地プレート孔９ａを穿設し、これらの下地プレート孔９ａに手摺子２が取り付けられるため、手摺子２を取り付ける位置決め作業を容易に行うことができる。さらに、下地プレート９には化粧材１０が取り付けられるため、下地プレート９の露出を防ぐことができ、美観を損なうことなく手摺子２を取り付けることができる。   Moreover, since the base plate hole 9a is drilled in advance in the base plate 9 attached to the landing 4 and the handrail 2 is attached to these base plate holes 9a, the positioning operation for attaching the handrail 2 can be easily performed. . Furthermore, since the decorative material 10 is attached to the base plate 9, the exposure of the base plate 9 can be prevented, and the handrail 2 can be attached without impairing the aesthetic appearance.
