Description
本考案は、開き戸、引き戸等の鋼製扉の製作に関し、より詳細には、金属板を曲げ加工して作られた前後両面の表面板と扉心材によって構成されて、建造物の壁面開口部に取り付けられる鋼製扉の扉小口面ネジ組み立て型金属製扉に関するものである。 The present invention relates to the production of steel doors such as hinged doors and sliding doors. More specifically, the present invention is composed of front and rear surface plates made by bending a metal plate and a door core material. This invention relates to a metal door with a small face screw assembled type of a steel door attached to the door.
例えば、ビル用の鋼製ドアとして、縦横に框組みされた金属製芯材の前後両面に、金属板材よりなるパネルを接合し、さらに金属板材周縁の小口部を溶接接合し、扉に剛性を持たせている金属製扉が広く知られている。上述した金属製扉一式は、溶接接合することで、比較的、簡単に組み立てることが可能であるが、サンダー掛け、パテ処理等の仕上げ工程の手間や鋼板のメッキ層を削り落とすことによる錆びの発生等の問題を抱えている。 For example, as a steel door for buildings, panels made of metal plates are joined to both the front and rear surfaces of a metal core that is vertically and horizontally braided. Metal doors are widely known. The set of metal doors described above can be assembled relatively easily by welding. However, it takes time to finish the sanding process, putty processing, etc. Have problems such as outbreaks.
そこで、製扉に対する軽量性をもって剛性を高めるため、左右両縁の木製芯材に金属製補強材を組み合わせてなるフラッシュドアが提案されている。
金属製補強材は、例えば、断面溝形に形成されて木製芯材の内側に嵌め被せられており、また、該金属製補強材に横方向の芯材や桟材等が接合されている(下記特許文献1、2参照)。
Therefore, in order to increase rigidity with light weight with respect to the door, a flash door is proposed in which a metal reinforcing material is combined with a wooden core on both left and right edges.
The metal reinforcing material is, for example, formed in a cross-sectional groove shape and fitted inside a wooden core material, and a horizontal core material, a crosspiece, or the like is joined to the metal reinforcing material ( See Patent Documents 1 and 2 below).
しかしながら、このフラッシュドアの場合、木製芯材と金属製補強材とを組み合わせるため、その分だけ部品点数が増えてコストアップにつながる上、組立に手間が掛かり、廃棄時にも両者の分離が困難であるという問題があった。また、従来のフラッシュドアの場合、芯材の前後各面に1枚物のパネルを貼り付けたものであったため、ドアの表面形態が一様となり、デザイン性に欠けるきらいがあった。 However, in the case of this flush door, the combination of a wooden core material and a metal reinforcing material increases the number of parts, which leads to increased costs, takes time for assembly, and makes it difficult to separate the two at the time of disposal. There was a problem that there was. Further, in the case of a conventional flash door, since a single panel is attached to each of the front and rear surfaces of the core material, the surface form of the door is uniform and there is a tendency that the design is lacking.
部品点数が少なく、反りや捻れに対する高い剛性が得られ、組立作業や廃棄時の異種材料毎の分離作業で容易なドアを提供するために、ドアは、木質板材よりなる前後2枚のパネルと、金属形材または樹脂形材よりなりかつ前後パネルを保持する左右1対の垂直なフレームとを備え、左フレームは、前後パネル内面の左縁部間に介在される芯部と、芯部に連なってその前後両側に設けられかつ前後パネルの左縁部がそれぞれ嵌め入れられる断面溝形の2つのパネル受け部とを有し、右フレームは、前後パネル内面の右縁部間に介在される芯部と、芯部に連なってその前後両側に設けられかつ前後パネルの右縁部がそれぞれ嵌め入れられる断面溝形の2つのパネル受け部を有しているものが提案されている(特許文献3参照)。 In order to provide a door with a small number of parts, high rigidity against warping and twisting, and easy separation by dissimilar materials during assembly work or disposal, the door is made up of two panels made of wood board A left and right pair of vertical frames made of a metal shape or a resin shape and holding the front and rear panels, and the left frame includes a core portion interposed between the left edges of the inner surfaces of the front and rear panels; And two panel receiving portions each having a groove shape that is provided on both the front and rear sides of the front and rear panels and into which the left edge portions of the front and rear panels are respectively fitted. The right frame is interposed between the right edge portions of the inner surfaces of the front and rear panels. There has been proposed a core portion and two panel receiving portions that are provided on both the front and rear sides of the core portion and into which the right edge of the front and rear panel is respectively fitted (Patent Literature). 3).
壁面垂直方向の荷重に対する壁板や扉板のたわみ剛性を向上させるために、壁面や扉面の2つの対角線上を結ぶ直線部に補強部材を壁面に接合し、その交点部分に中央部材を設け、中央部材を直線部の補強部材と壁面の両者に接合する構造とすることで、壁面のたわみ剛性を向上することが提案されている(特許文献4参照)。 In order to improve the deflection rigidity of the wall plate and door plate against the load in the vertical direction of the wall surface, a reinforcing member is joined to the wall surface at a straight line connecting two diagonal lines of the wall surface and door surface, and a central member is provided at the intersection In addition, it has been proposed to improve the deflection rigidity of the wall surface by joining the central member to both the reinforcing member and the wall surface of the straight portion (see Patent Document 4).
扉枠の組立てにおいて、溶接作業を行わずに、低コスト化とともに、予め表面を化粧した金属板の使用を可能にした扉枠を提供として、2本の縦枠と、1本の上枠と、1本の下枠とからなり、前記上枠の両端部を前記左右の縦枠の上端部に結合し、前記下枠の両端部を前記左右の縦枠の下端部に結合して扉枠を構成し、この扉枠に扉を収容するようにした扉枠において、前記各結合部におけるいずれか一方の端面部に係止舌片を形成し、前記各結合部におけるいずれか他方の側面部又は上面部に係止孔を形成し、この係止舌片を、係止孔に嵌め込み折り曲げ、取付け孔側から固定部材としての固定ねじを差し込み、さらに、取付け孔に捩じ込むことで固定してなる扉枠が提案されている(特許文献5参照)。 In assembling the door frame, it is possible to provide a door frame that enables the use of a metal plate whose surface has been pre-decorated as well as cost reduction without performing welding work. The door frame is composed of one lower frame, the both ends of the upper frame are coupled to the upper ends of the left and right vertical frames, and the both ends of the lower frame are coupled to the lower ends of the left and right vertical frames. In the door frame in which the door is accommodated in the door frame, a locking tongue piece is formed on any one end surface portion in each coupling portion, and the other side surface portion in each coupling portion Alternatively, a locking hole is formed in the upper surface, and this locking tongue piece is fitted into the locking hole and bent, and a fixing screw as a fixing member is inserted from the mounting hole side, and further fixed by screwing into the mounting hole. A door frame is proposed (see Patent Document 5).
棒状金属建材の側面に溝を付け,ツメを付けた建材をはめ込み溶接する接合方法で,化粧版でカバーすることを前提にして,溶接による汚れを研磨する工程を省くことができる工法が提案されている(特許文献6参照)。 It is a joining method in which a groove is formed on the side of a bar-shaped metal building material, and the building material with a claw is fitted and welded. A construction method that eliminates the process of polishing dirt from welding on the assumption that it is covered with a decorative plate is proposed. (See Patent Document 6).
従来,金属建材の接合は,溶接によることが多く、その場合、溶接ビートは表しのままとなっているが、建具となると溶接ビード部をそのままにして仕上げ塗装をすることは出来ない。その為、溶接部は溶接していない部分と同じ凹凸になるまで、サンダー等で仕上げていて、仕上げに多くの時間を費やし、扉完成までの時間短縮の最大のネックとなっている。そこで、溶接組み立てと同じ剛性を持ち、溶接に変わる早い固着方法が望まれている。 Conventionally, joining of metal building materials is often performed by welding, and in that case, the welding beat remains as it is, but when it becomes a joinery, it is not possible to finish paint with the weld bead portion as it is. For this reason, the welded part is finished with a sander or the like until it has the same unevenness as the unwelded part, and it takes a lot of time to finish, which is the biggest bottleneck in shortening the time to complete the door. Therefore, there is a demand for a fast fixing method that has the same rigidity as the welding assembly and changes to welding.
前記前後の表面板の小口突合せ接合部をネジ止めで固定する方法を採用し、この方法は,前記前後の2枚の表面板材を接合していない為、扉の剛性力を高めることが必要になる。扉の心材の部材配置及び接合位置などを変え、使用吊り金具に適応した心材を組み立て、剛性力を高めている。 Adopting a method to fix the front and rear surface plate butt joints with screws, and this method does not join the two front and rear surface plates, so it is necessary to increase the rigidity of the door Become. By changing the arrangement and joining position of the core material of the door, the core material suitable for the hanging bracket used is assembled to increase the rigidity.
一般的に、扉の組み立て方法は、片方の表面板に力骨、中骨を所定の数、所定の位置に構造用粘着テープを利用し、配設後、骨同士の突合せ部を溶接接合し、他方の表面板を被せて、表面板の小口突合せ部を溶接接合することが多い。しかし、この方法では、組み立てられた扉の小口を全長に渡り、サンダー仕上げが必要になり、又錆止め塗装工程前にパテ処理も必要になり、扉の組み立て時間を短縮できないという課題を残している。詳しくは、扉の小口面において、曲げ誤差に依る突合せ部のずれ、溶接接合に依るビードの凸部など、表面形状の変形を平らにする研磨が必要になり、その上、研磨に依るメッキ層の削り剥がれが耐候性を落とすという課題も残している。 In general, the door is assembled by using a predetermined number of strength bones and central bones on one surface plate and a structural adhesive tape at a predetermined position. In many cases, the other face plate is covered and the small edge butt portion of the face plate is welded. However, this method requires a sander finish over the entire length of the assembled door, and also requires putty treatment before the rust-prevention coating process, leaving the problem that the door assembly time cannot be shortened. . Specifically, on the small edge of the door, it is necessary to polish to flatten the deformation of the surface shape, such as deviation of the butt part due to bending error, bead convex part due to welding joint, and plating layer depending on polishing There is also a problem that the shaving off of the steel deteriorates the weather resistance.
本考案は、2枚の表面板と心材を組み立てて製造する扉において、3面もしくは4面の扉小口面の接合をネジ部材の利用により、組み立て作業を行い、作業工程の簡素化による低コスト化、めっき鋼板の防錆性能の維持を目的とするものである。表面板を一体化しないことに依る扉の剛性力の低下が懸念される為、扉の重心の位置と使用される吊り金具を考慮して、扉の心材の配置及び当接部の固着方法を変える課題が新たに出てくる。目的は、作業工程の簡素化、反りや捻れに対する剛性の維持、組立作業や廃棄時の異種材料毎の分離作業が容易である扉を提供することにある。また、他の目的は、表面形態の多様化が可能であって、デザイン性に優れた扉などドア一式を簡単に組み立てることにある。 The present invention is a door manufactured by assembling two face plates and a core material, and the assembly work is performed by using a screw member to join the three or four door facets. The purpose is to maintain the rust prevention performance of the steel plate. Because there is a concern about the reduction in the rigidity of the door due to the fact that the surface plate is not integrated, the position of the center of the door and the fixing method of the abutting part should be considered in consideration of the position of the center of gravity of the door and the hanging bracket used. New challenges will emerge. The object is to provide a door that simplifies the work process, maintains rigidity against warping and twisting, and facilitates separation work for different materials during assembly work and disposal. Another object is to easily assemble a set of doors such as a door that can be diversified in surface form and has excellent design.
