Description

本発明は、ドア枠と開口部枠材の固定構造及び方法に関するものである。 The present invention relates to a structure and method for fixing a door frame and an opening frame member.

一般に、ドア枠は、現場において、建物躯体側の構造体に固定されることで、ドアによって開閉される開口部を形成する。また、ドア枠は、当該ドア枠の背面に設けた要素(アンカーと称する場合がある)を建物躯体側の構造体に溶接することで固定される場合が多い(特許文献1)。 Generally, a door frame is fixed to a structure on the building frame side at a site, thereby forming an opening that can be opened and closed by a door. Moreover, a door frame is often fixed by welding an element (sometimes referred to as an anchor) provided on the back side of the door frame to a structure on the building frame side (Patent Document 1).

しかしながら、ドア枠を溶接によって固定するやり方は、火気作業ができない現場で採用することができず、また、溶接作業には熟練の技術が必要となるため、施工技術者の確保も問題となる。したがって、ドア枠を、溶接作業を用いずに、建物躯体側の構造体に固定したいというニーズがある。 However, fixing the door frame by welding cannot be used at sites where hot work is not possible, and since welding requires skilled techniques, there is also a problem in securing construction engineers. Therefore, there is a need to fix the door frame to the structure of the building frame without using welding work.

ドア枠は、建物躯体側の構造体に対して位置調整を行ってから当該構造体に固定される。例えば、特許文献2には、溶接作業を伴うことなく、鋼板製の枠体を建物駆体の開口部に装着する枠材の固定構造が開示されている。ここで、ドア枠の位置調整は、見付方向の位置調整に留まらない。例えば、ドア枠が取り付けられる躯体側の構造体が前後方向に傾いているような場合には、当該構造体に取り付けたドア枠も前後方向に傾いてしまうおそれがあり、ドア枠の姿勢調整(傾きないし倒れを調整して垂直姿勢とする)を行って固定する必要がある。 The door frame is fixed to the structure after adjusting its position with respect to the structure on the building frame side. For example, Patent Document 2 discloses a frame fixing structure in which a steel plate frame is attached to an opening of a building structure without welding. Here, the position adjustment of the door frame is not limited to position adjustment in the facing direction. For example, if the structure on the frame side to which the door frame is attached is tilted in the front-rear direction, there is a risk that the door frame attached to the structure will also tilt in the front-rear direction. It is necessary to fix it by adjusting the tilting or falling to a vertical position.

本発明の実施形態を図面に基づいて詳細に説明する。図1~図4は第1実施形態を示し、図5~図8は第2実施形態を示す。図1、図5は、それぞれ建物開口部に取り付けられたドア枠の正面図であって、仕上げの壁パネルW(図2参照)は省略されており、いわば、壁パネルWが取り付けられる前の状態を示している。本実施形態に係るドア枠は、上枠1と、左右の縦枠2と、からなる三方枠であり、三方枠であるドア枠と床面FLで囲まれた空間が建物開口部となっており、図示しないドアによって当該建物開口部が開閉されるようになっている。図示の態様のドア枠は、開き戸用であるが、ドアの種類は限定されない。 Embodiments of the present invention will be described in detail based on the drawings. 1 to 4 show a first embodiment, and FIGS. 5 to 8 show a second embodiment. 1 and 5 are front views of a door frame installed in a building opening, respectively, and the finished wall panel W (see FIG. 2) is omitted. It shows the condition. The door frame according to the present embodiment is a three-sided frame consisting of an upper frame 1 and left and right vertical frames 2, and the space surrounded by the door frame, which is the three-sided frame, and the floor surface FL serves as a building opening. The building opening is opened and closed by a door (not shown). Although the illustrated door frame is for a hinged door, the type of door is not limited.

三方枠であるドア枠は、工場において、左右の金属製(例えば、スチール製)の縦枠2の上端を金属製(例えば、スチール製)の上枠1の長さ方向両端にそれぞれ固定(溶接、螺子止め等)することで組み立てられる。すなわち、ドア枠は工場で組み立てられて、現場に搬入され、躯体側の構造体に固定される。本実施形態では、躯体側の構造体は、開口部枠材3と、開口部枠材3が固定されたスタッド4、ランナー4´から構成されており、ドア枠は開口部枠材3に取り付けられる。なお、三方枠のドア枠は例示であって、ドア枠は下枠(沓摺)を備えた四周枠であってもよい。 A three-sided door frame is manufactured by fixing (welding) the upper ends of left and right metal (e.g., steel) vertical frames 2 to the longitudinal ends of metal (e.g., steel) upper frames 1 at the factory. , screws, etc.). That is, the door frame is assembled at a factory, transported to the site, and fixed to the frame structure. In this embodiment, the structure on the frame side is composed of an opening frame material 3, studs 4 to which the opening frame material 3 is fixed, and runners 4', and the door frame is attached to the opening frame material 3. It will be done. Note that the door frame having a three-sided frame is an example, and the door frame may be a four-circumferential frame provided with a lower frame (slat).

ドア枠の構成について、主として縦枠2の構成に基づいて説明する。ドア枠の構成は、第1実施形態と第2実施形態で共通である。図2に示すように、左右の縦枠2は、高さ方向(垂直方向)に延びる長尺部材であって、第1見付面20と、第2見付面21と、第1見付面20と第2見付面21の内側端を接続する内側見込部22と、第1見付面20の外側端から見込方向に延びる第1外側見込辺23と、第2見付面21の外側端から見込方向に延びる第2外側見込辺24と、からなる。内側見込部22は、第1見付面20の内側端から見込方向に延びる第1内側見込面220と、第2見付面21の内側端から見込方向に延びる第2内側見込面221と、第1内側見込面220と第2内側見込面221の間に位置した凸状の中央見込部222と、からなる。縦枠2(特に、内側見込部22)の断面形状は限定されない。一方(戸尻側)の縦枠2の第1内側見込面220には、高さ方向に間隔を存して複数のヒンジ要素Hが設けてある。 The structure of the door frame will be explained mainly based on the structure of the vertical frame 2. The structure of the door frame is common between the first embodiment and the second embodiment. As shown in FIG. 2, the left and right vertical frames 2 are elongated members extending in the height direction (vertical direction), and have a first indexing surface 20, a second indexing surface 21, and a first indexing surface 20. An inner prospecting portion 22 connecting the inner end of the surface 20 and the second finding surface 21 , a first outer prospecting side 23 extending in the prospecting direction from the outer end of the first finding surface 20 , and a second finding surface 21 . It consists of a second outer prospect side 24 extending from the outer end in the prospect direction. The inner prospecting section 22 includes a first inner prospecting surface 220 extending in the prospecting direction from the inner end of the first finding surface 20, and a second inner prospecting surface 221 extending in the prospecting direction from the inner end of the second finding surface 21. It consists of a convex central prospecting portion 222 located between a first inner prospecting surface 220 and a second inner prospecting surface 221 . The cross-sectional shape of the vertical frame 2 (in particular, the inner prospective portion 22) is not limited. On the first inner facing surface 220 of the vertical frame 2 on one side (on the door end side), a plurality of hinge elements H are provided at intervals in the height direction.

図2、図9等に示すように、縦枠2において、第1外側見込辺23と第2外側見込辺24は離間しており、第1外側見込辺23と第2外側見込辺24の間には、縦枠2の高さ方向に間隔を存して複数の帯状見込片25が固定(溶接、螺子止め等)されており、縦枠2の強度を向上させている。帯状見込片25は、見込方向に延びる横長方形状の金属板であり、見込方向の中央部位には雌螺子としてのナット26が固定されている。帯状見込片25は、縦枠2を躯体側の構造体に取り付けるための取付手段の1つを構成している。 As shown in FIG. 2, FIG. 9, etc., in the vertical frame 2, the first outside expected side 23 and the second outside expected side 24 are spaced apart, and between the first outside expected side 23 and the second outside expected side 24. A plurality of strip-shaped prospective pieces 25 are fixed (welded, screwed, etc.) at intervals in the height direction of the vertical frame 2, thereby improving the strength of the vertical frame 2. The strip-like prospect piece 25 is a horizontally rectangular metal plate extending in the direction of the prospect, and a nut 26 as a female screw is fixed to the central portion in the direction of the prospect. The strip-like prospective piece 25 constitutes one of the attachment means for attaching the vertical frame 2 to the structure on the frame side.

上枠1は、開口幅方向(水平方向)に延びる長尺部材であって、本実施形態では、縦枠2と同一の断面形状を備えている。すなわち、縦枠2を、内側見込部22が下面となり、帯状見込片15が上側に位置して開口幅方向に延びるように向けた時の姿勢にしたがって上枠1を説明することができる。より具体的には、上枠1は、第1見付面10と、第2見付面11と、第1見付面10と第2見付面11の内側端(下端)を接続する内側見込部(下面部)12と、第1見付面10の外側端(上端)から見込方向に延びる第1外側(上側)見込辺13と、第2見付面11の外側端(上端)から見込方向に延びる第2外側(上側)見込辺14と、からなる(図9参照)。なお、上枠1の断面形状は、縦枠2と同様に限定されない。 The upper frame 1 is a long member extending in the opening width direction (horizontal direction), and has the same cross-sectional shape as the vertical frame 2 in this embodiment. That is, the upper frame 1 can be described according to the posture when the vertical frame 2 is oriented so that the inner prospective portion 22 is the lower surface, the band-like prospective piece 15 is located on the upper side, and extends in the opening width direction. More specifically, the upper frame 1 includes a first finding surface 10, a second finding surface 11, and an inner side connecting the inner ends (lower ends) of the first finding surface 10 and the second finding surface 11.

本実施形態に係る躯体側の構造体は、ドア枠が固定される開口部枠材(補強枠材と称される場合もある)3と、開口部枠材3が固定されている下地枠材と、から構成されている。下地枠材は、垂直方向に延びる左側のスタッド4と、右側のスタッド4の高さ方向の上側の所定部位間を水平に連結するランナー4´と、左右のスタッド4の下端部位を水平に連結するランナー(図示せず)と、を含む。典型的には、開口部枠材3、スタッド4、ランナーは金属製(例えば、スチール製)である。開口部枠材3、スタッド4の構成は、第1実施形態と第2実施形態で共通である。 The frame-side structure according to the present embodiment includes an opening frame material (sometimes referred to as a reinforcing frame material) 3 to which the door frame is fixed, and a base frame material to which the opening frame material 3 is fixed. It is composed of and. The base frame material horizontally connects the left stud 4 that extends vertically, a runner 4' that horizontally connects a predetermined portion above the right stud 4 in the height direction, and horizontally connects the lower end portions of the left and right studs 4. and a runner (not shown). Typically, the opening frame member 3, stud 4, and runner are made of metal (for example, steel). The configurations of the opening frame material 3 and the studs 4 are the same in the first embodiment and the second embodiment.

図4に示すように、スタッド4は、第1見付辺40、第2見付辺41、見込辺42とから断面視コ字形状を備え、高さ方向に延びる長尺部材であり、見込辺42を開口部側に位置させた垂直姿勢で設けてある。ランナー4´は、スタッド4と実質的に同じ断面形状を備え、水平方向に延びる長尺部材であり、見込辺を開口部側(下側)に位置させた向きで設けてある。 As shown in FIG. 4, the stud 4 is an elongated member that has a U-shape in cross section from a first found side 40, a second found side 41, and an expected side 42, and extends in the height direction. It is provided in a vertical position with the side 42 located on the opening side. The runner 4' is an elongated member that has substantially the same cross-sectional shape as the stud 4 and extends in the horizontal direction, and is provided with its prospective side positioned on the opening side (lower side).

図4に示すように、開口部枠材3は、第1見付辺30、第2見付辺31、見込辺32とから断面視コ字形状を備えた長尺部材である。開口部枠材3は、見込辺32を開口部側に位置させた垂直姿勢でスタッド4に固定され、見込辺32を開口部側(下側)に位置させた水平姿勢でランナー4´に固定される。より具体的には、開口部枠材3の第1見付辺30、第2見付辺31の先端は内側に折り曲げて折り曲げ片300、310が形成されており、開口部枠材3は、折り曲げ片300、310をスタッド4の見込辺42、ランナー4´の見込辺に当接させて固定されている。開口部枠材3の固定手段としては溶接が例示される。開口部枠材3を取り付ける段階では、火気作業が問題となるような可燃物が現場に存在しないため、溶接を用いることによる不具合は生じない。なお、開口部枠材3を螺子を用いてスタッド4、ランナー4´に固定してもよい。 As shown in FIG. 4, the opening frame member 3 is an elongated member having a U-shape in cross section including a first found side 30, a second found side 31, and an expected side 32.

More specifically, the tips of the first facing side 30 and the second facing side 31 of the opening frame material 3 are bent inward to form bent pieces 300 and 310, and the opening frame material 3 is The bent pieces 300 and 310 are fixed in contact with the expected side 42 of the stud 4 and the expected side of the runner 4'. Welding is exemplified as a means for fixing the opening frame member 3. At the stage of attaching the opening frame material 3, there are no combustible materials on site that would cause problems with hot work, so no problems will occur due to the use of welding. Note that the opening frame member 3 may be fixed to the stud 4 and runner 4' using screws.

このように、本実施形態では、建物躯体側の構造体は、開口部枠材3、スタッド4、ランナー4´から構成されており、ドア枠(上枠1と左右の縦枠2からなる三方枠)は、躯体側の構造体(開口部枠材3)に対して位置調整を行って位置決めした上で固定される。この位置調整には、開口部枠材3に対するドア枠の見付方向の位置調整が含まれる。ドア枠の見付方向の位置調整は、主として、図2、図6、図10、図11におけるX方向、Z方向の位置調整である。 As described above, in this embodiment, the structure on the building frame side is composed of the opening frame material 3, the studs 4, and the runners 4', and the door frame (three-sided structure consisting of the upper frame 1 and the left and right vertical frames 2). The frame) is fixed after being positioned by adjusting the position relative to the structure on the frame side (opening frame member 3). This position adjustment includes position adjustment of the door frame relative to the opening frame member 3 in the facing direction. The position adjustment of the door frame in the facing direction is mainly the position adjustment in the X direction and the Z direction in FIGS. 2, 6, 10, and 11.

図10、図11を参照しつつ、ドア枠の見付方向の位置調整について説明する。図10、図11は専らドア枠の見付方向の位置調整を説明するための図であり、図10、図11に示すドア枠(上枠1´、左右の縦枠2´)と開口部枠材3との固定構造は、本実施形態に係るドア枠の固定構造と異なる点に留意されたい。躯体側の構造体である開口部枠材3によって囲まれる縦長方形状の空間の寸法は、ドア枠(上枠1´、左右の縦枠2´)の外形寸法よりも少し大きく、ドア枠の背面側の見込面(第1外側見込辺23、第2外側見込辺24)と開口部枠材3の見込辺32とは隙間を介して離間対向するようになっている。この隙間の寸法(X方向の寸法、Z方向)を調整することによって、開口部枠材3に対するドア枠の見付方向の位置調整を行う。なお、開口部枠材3に対するドア枠の見込方向(Y方向)のおおまかな位置調整を行ってもよい。 Adjustment of the position of the door frame in the facing direction will be described with reference to FIGS. 10 and 11. 10 and 11 are diagrams exclusively for explaining the position adjustment of the door frame in the finding direction, and the door frame (upper frame 1', left and right vertical frames 2') and opening shown in FIGS. It should be noted that the fixing structure with the frame material 3 is different from the fixing structure of the door frame according to this embodiment. The dimensions of the vertical rectangular space surrounded by the opening frame material 3, which is the structure on the frame side, are slightly larger than the external dimensions of the door frame (upper frame 1', left and right vertical frames 2'), and The prospective surface on the back side (the first outer prospective side 23, the second outer prospective side 24) and the prospective side 32 of the opening frame member 3 are spaced apart from each other and face each other through a gap. By adjusting the dimensions of this gap (dimensions in the X direction, Z direction), the position of the door frame relative to the opening frame member 3 in the facing direction is adjusted. Note that the approximate position of the door frame relative to the opening frame member 3 in the expected direction (Y direction) may be adjusted.

具体的な調整手法としては、いわゆる楔Kを用いる手法を例示することができる。断面視直角三角形の楔Kを第1側及び第2側から見込方向に上記隙間に差し込み、2つの楔Kを傾斜面同士が重なるように組み合わせて(楔セット)、傾斜面の重なりの程度によって、楔セットの厚さが可変となっており、楔セットの厚さによってドア枠と開口部枠材との隙間を決定する。図示の楔Kは例示であって、楔の形状は断面視直角三角形に限定されず、また、隙間に挿入される楔の個数も限定されず、1個でも3個以上であってもよい。 As a specific adjustment method, a method using a so-called wedge K can be exemplified. Insert a wedge K with a right-angled triangular cross-sectional view into the gap from the first and second sides in the perspective direction, and combine the two wedges K so that their sloped surfaces overlap (wedge set), depending on the degree of overlap of the sloped surfaces. The thickness of the wedge set is variable, and the gap between the door frame and the opening frame material is determined by the thickness of the wedge set. The illustrated wedge K is an example, and the shape of the wedge is not limited to a right triangle in cross section, and the number of wedges inserted into the gap is not limited either, and may be one or three or more.

図10に示す例では、上枠1´の左右両端部位、左右の縦枠2´の上方部位及び下方部位、左右の縦枠2´の下端に楔セットを設けることで、ドア枠の見込方向の位置調整を行いつつ、ドア枠の位置(X方向の位置、Z方向の位置)を仮固定する。複数の楔セットを用いて仮固定されたドア枠を開口部枠材3に固定した後で、楔Kを取り外す。 In the example shown in FIG. 10, wedge sets are provided at both left and right end portions of the upper frame 1', at the upper and lower portions of the left and right vertical frames 2', and at the lower ends of the left and right vertical frames 2', so that the expected direction of the door frame is While adjusting the position of the door frame, temporarily fix the position of the door frame (position in the X direction and position in the Z direction). After the temporarily fixed door frame is fixed to the opening frame material 3 using a plurality of wedge sets, the wedges K are removed.

本実施形態においても、上枠1の左右両端部位、左右の縦枠2の上方部位及び下方部位に位置して、楔を挿入する隙間(楔挿入部K´)が形成されており(図1、図3、図5、図7参照)、楔を用いてドア枠の見付方向の位置調整を行うことができる。本実施形態では、さらに、楔を挿入する際に、ドア枠の見込方向(Y方向)の位置調整も行う。ここで、ドア枠の見込方向の位置調整には、ドア枠の前後方向の倒れの調整が含まれる。 In this embodiment as well, gaps (wedge insertion portions K') into which wedges are inserted are formed at both left and right end portions of the upper frame 1 and at upper and lower portions of the left and right vertical frames 2 (Fig. 1 , FIG. 3, FIG. 5, and FIG. 7), the position of the door frame in the facing direction can be adjusted using a wedge. In this embodiment, when inserting the wedge, the position of the door frame in the expected direction (Y direction) is also adjusted. Here, adjusting the position of the door frame in the expected direction includes adjusting the inclination of the door frame in the front-rear direction.
