【０００２】[0002]
住宅、倉庫、宿舎等のいわゆるスチ−ルハウスにおいては、スチ−ル製のフレ −ムを結合することにより建物の枠組を構成している。フレ−ムは、一般に板厚 が０．８〜１．５ｍｍ程度の鋼材が用いられ、基板部とこの基板部の両側縁から 立上がる立上り部を有して断面が略コ状に形成されている。そして、フレ−ムの 表面は防錆処理されている。 In a so-called steel house such as a house, a warehouse, or a dormitory, a frame of a building is constructed by connecting steel frames. The frame is generally made of a steel material having a plate thickness of 0.8 to 1.5 mm, and has a substantially U-shaped cross section with a substrate portion and rising portions rising from both side edges of the substrate portion. There is. The surface of the frame is rustproof.
【０００３】 前記スチ−ルハウスは、前記フレ−ム相互を接合して土台、柱、梁および棟等 を構築し、この骨組にスチ−ルパネルあるいは石膏ボ−ド等を張り合わせるなど して取り付け、壁、床、屋根等を構成している。In the steel house, the frames are joined to each other to construct a base, a pillar, a beam, a ridge, and the like, and a frame panel, a gypsum board, or the like is attached to the frame to attach the frame, It comprises walls, floors, roofs, etc.
【０００４】 ところで、前記フレ−ム相互を接合するには、従来、溶接、ボルト・ナット締 め等の連結手段が取られ、フレ−ム相互を直角または角度を持って連結すること により、骨組を構築している。By the way, in order to join the frames to each other, conventionally, a connecting means such as welding, bolting and nut tightening is taken, and the frames are connected to each other at a right angle or at an angle. Is building.
【０００５】[0005]
すなわち、スチ−ルハウス等の骨組の構築において、例えば、柱となる第１の フレ−ムと横桟となる第２のフレ−ムとを端部相互で直角に接合する場合、第１ のフレ−ムの立上り部と第２のフレ−ムの立上り部とを接合し、立上り部相互を ボルト・ナットによって締め付けるか、溶接によって結合している。 That is, in the construction of a frame such as a steel house, for example, when the first frame that serves as a pillar and the second frame that serves as a cross rail are joined at right angles to each other, the first frame is joined. -The rising portion of the frame and the rising portion of the second frame are joined, and the rising portions are fastened together by bolts and nuts or welded together.
【０００６】 しかし、第１のフレ−ムと第２のフレ−ムとをボルト・ナットにより締め付け て直角に結合するためにはフレ−ムにボルト孔を開け、第１のフレ−ムと第２の フレ−ムとを直角に位置決めした状態で、そのボルト孔にボルトを挿通してボル ト・ナットによって締め付ける現場作業が必要であり、フレ−ム相互を溶接する 上においても、第１のフレ−ムと第２のフレ−ムとを直角に位置決めした状態で 溶接する必要があり、その作業が煩雑となる。また、ボルト・ナットの締め付け により両フレ−ムを強固に結合すると、例えば地震等のときに振動を吸収するこ とができず、結合部に歪みが生じて亀裂が発生したり、変形、折損することがあ る。また、溶接の場合にも同様なことが言えると共に、フレ−ムに施された防錆 処理が劣化されて錆が発生しやすいという問題がある。However, in order to fasten the first frame and the second frame with bolts and nuts to connect them at a right angle, a bolt hole is opened in the frame, and the first frame and the second frame are connected. It is necessary to insert a bolt into the bolt hole and fasten it with a bolt and nut in a state where it is positioned at a right angle to the second frame, and even when welding the frames to each other, the first work is required. It is necessary to weld the frame and the second frame at right angles, which complicates the work. Also, if both frames are firmly joined by tightening the bolts and nuts, vibration cannot be absorbed, for example, in the event of an earthquake, etc., and the joint will be distorted and cracked, deformed or broken. There is something to do. In addition, the same can be said in the case of welding, and there is a problem that the rust preventive treatment applied to the frame is deteriorated and rust easily occurs.

【０００９】[0009]
以下、この考案の実施の形態を図面に基づいて説明する。 図１に示すように、フレ−ム構造は、第１のフレ−ム１と第２のフレ−ム２と から構成されている。第１および第２のフレ−ム１、２は、基本的に同一構造で あり、板厚が０．８〜１．５ｍｍ程度の鋼材、鉄材、鉄合金材、アルミニウム合 金材等によって基板部１ａ、２ａと、この基板部１ａ、２ａの両側縁から立上る 立上り部１ｂ、２ｂを有して断面が略コ字状に構成されている。そして、第１お よび第２のフレ−ム１、２の表面には防錆処理が施されている。 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the frame structure is composed of a first frame 1 and a second frame 2. The first and second frames 1 and 2 have basically the same structure, and are made of a steel material, an iron material, an iron alloy material, an aluminum alloy material or the like having a plate thickness of about 0.8 to 1.5 mm, which is a substrate portion. The cross section is formed in a substantially U-shape, having 1a and 2a and rising portions 1b and 2b rising from both side edges of the substrate portions 1a and 2a. The surfaces of the first and second frames 1 and 2 are anticorrosive.
【００１０】 第１のフレ−ム１の端部には基板部１ａを立上り部１ｂの端部より突出した基 板突出部３が設けられている。また、第２のフレ−ム２の端部には立上り部２ｂ を基板部２ａの端部より突出した立上り突出部４が設けられている。 また、第１のフレ−ム１の基板部１ａの端部および基板突出部３には後述する タッピングねじを挿通するための、それぞれ２個の下穴５、６が穿設されている 。さらに、第２のフレ−ム２の基板部２ａの端部および立上り突出部４には後述 するタッピングねじを挿通するための、それぞれ２個の下穴７、８が穿設されて いる。そして、第１のフレ−ム１の基板突出部３に穿設された下穴６は第２のフ レ−ム２の基端部２ａに穿設された下穴７と対応するように同一間隔に配置され ている。At the end of the first frame 1, there is provided a base plate projecting portion 3 which projects the substrate portion 1 a from the end of the rising portion 1 b. Further, a rising protrusion 4 is provided at the end of the second frame 2 so that the rising portion 2b protrudes from the end of the substrate 2a. Further, two pilot holes 5 and 6 for inserting tapping screws, which will be described later, are formed in the end portion of the board portion 1a of the first frame 1 and the board projecting portion 3. Further, two pilot holes 7 and 8 for inserting a tapping screw, which will be described later, are formed in the end portion of the base plate portion 2a of the second frame 2 and the rising protrusion portion 4, respectively. Then, the prepared hole 6 formed in the substrate projecting portion 3 of the first frame 1 is the same as the prepared hole 7 formed in the base end portion 2a of the second frame 2 so as to correspond. It is arranged at intervals.
【００１１】 次に、図２〜図５に基づいて例えば柱となる第１のフレ−ム１と例えば横桟と なる第２のフレ−ム２とを接合する手順を説明すると、まず、第１のフレ−ム１ の立上り部１ｂを第２のフレ−ム２の立上り部２ｂの内側に嵌入して立上り部１ ｂ、２ｂ相互を接合すると共に、第１のフレ−ム１の立上り部１ｂの端面を第２ のフレ−ム２の基板部２ａの内面に当接して第１のフレ−ム１と第２のフレ−ム ２とを直角に位置決めする。Next, a procedure for joining the first frame 1 which is, for example, a pillar and the second frame 2 which is, for example, a horizontal rail will be described with reference to FIGS. The rising portion 1b of the first frame 1 is fitted inside the rising portion 2b of the second frame 2 to join the rising portions 1b and 2b to each other, and the rising portion of the first frame 1 is joined. The end surface of 1b is brought into contact with the inner surface of the substrate portion 2a of the second frame 2 to position the first frame 1 and the second frame 2 at a right angle.
【００１２】 ついで、第１のフレ−ム１の基板突出部３を折り目線９に沿って折曲して第２ のフレ−ム２の基板部２ａの外側に接合すると共に、第２のフレ−ム２の立上り 突出部４を折り目線１０に沿って折曲して第１のフレ−ム１の基板部１ａの外側 に接合すると、第１のフレ−ム１の基板突出部３の下穴６と第２のフレ−ム２の 基板部２ａの下穴７とが対向し、第１のフレ−ム１の基板部１ａの下穴５と第２ のフレ−ム２の立上り突出部４の下穴８とが対向する。Next, the board protruding portion 3 of the first frame 1 is bent along the fold line 9 to be joined to the outside of the board portion 2a of the second frame 2, and the second frame -Rise of the frame 2 When the protruding portion 4 is bent along the crease line 10 and joined to the outside of the substrate portion 1a of the first frame 1, the lower portion of the substrate protruding portion 3 of the first frame 1 is The hole 6 and the pilot hole 7 of the base plate portion 2a of the second frame 2 face each other, and the pilot hole 5 of the base plate portion 1a of the first frame 1 and the rising protrusion of the second frame 2 The prepared hole 8 of 4 faces.
【００１３】 そこで、第１のフレ−ム１の基板突出部３の外側からタッピングねじ１１を下 穴６に挿入し、タッピングねじ１１を電動ドライバ等によってねじ込むと、下穴 ６および下穴７の内周面にタッピングねじ１１によってねじが立てられながら締 め付けられ、第１のフレ−ム１の基板突出部３と第２のフレ−ム２の基板部２ａ とが接合される。同様に、第２のフレ−ム２の立上り突出部４の外側からタッピ ングねじ１１を下穴８に挿入し、タッピングねじ１１を電動ドライバ等によって ねじ込むと、下穴８および下穴５の内周面にタッピングねじ１１によってねじが 立てられながら締め付けられ、第２のフレ−ム２の立上り突出部４と第１のフレ −ム１の基板部１ａとが接合される。この場合、タッピングねじ１１を完全に締 め付けることなく、タッピングねじ１１の頭部がフレ−ムに食い込まない程度で 締め付けを終わらせ、接合部に若干の遊びを持たせる。Therefore, when the tapping screw 11 is inserted into the pilot hole 6 from the outside of the board projecting portion 3 of the first frame 1 and the tapping screw 11 is screwed in with an electric screwdriver or the like, the pilot hole 6 and the pilot hole 7 are removed. The inner peripheral surface is tightened by a tapping screw 11 while being raised, and the substrate protruding portion 3 of the first frame 1 and the substrate portion 2a of the second frame 2 are joined. Similarly, when the tapping screw 11 is inserted into the pilot hole 8 from the outside of the rising protrusion 4 of the second frame 2 and the tapping screw 11 is screwed in by an electric screwdriver or the like, the inside of the pilot hole 8 and the pilot hole 5 is The peripheral surface is tightened while being raised by a tapping screw 11, and the rising protrusion 4 of the second frame 2 and the substrate portion 1a of the first frame 1 are joined. In this case, the tapping screw 11 is not completely tightened, and the tightening is finished without the head of the tapping screw 11 biting into the frame, so that the joint has some play.
【００１４】 したがって、第１のフレ−ム１の基板部１ａと第２のフレ−ム２の基板部２ａ とが直角に結合されて角部１２が形成される。このとき、タッピングねじ１１を 用いることにより、第１および第２のフレ−ム１、２にねじ穴を設ける必要がな く、下穴５〜８のみを穿設するだけでよく、前加工が容易である。またボルト・ ナットと異なり、タッピングねじ１１は締め付けてもフレ−ム相互を圧接する方 向に力が加わらず、ねじ部がフレ−ム自体に食い込むため、振動等によって緩み にくいという特徴があり、スチ−ルハウス等の骨組等の構築に有効である。Therefore, the substrate portion 1a of the first frame 1 and the substrate portion 2a of the second frame 2 are joined at a right angle to form a corner portion 12. At this time, by using the tapping screw 11, it is not necessary to form a screw hole in the first and second frames 1 and 2, and only the prepared holes 5 to 8 need to be drilled. It's easy. Also, unlike bolts and nuts, the tapping screw 11 does not exert a force in the direction in which the frames are pressed against each other even when tightened, and since the screw part bites into the frame itself, it is difficult to loosen due to vibration, etc. It is effective in constructing a framework such as a steel house.
【００１５】 さらに、第１のフレ−ム１と第２のフレ−ム２を接合部で強固に締め付けると 、地震等の振動が加わったとき、接合部で亀裂、変形、折損のおそれがあるが、 前述したように、タッピングねじ１１によって接合部に若干の遊びを持たせてお くことにより、地震等の振動が加わったとき、接合部で振動を吸収することがで き、接合部の亀裂、変形、折損を未然に防止でき、耐久性の向上を図ることがで きる。Furthermore, if the first frame 1 and the second frame 2 are firmly tightened at the joint, there is a risk of cracking, deformation, or breakage at the joint when vibration such as an earthquake is applied. However, as described above, the tapping screw 11 allows the joint to have some play, so that when the vibration such as an earthquake is applied, the vibration can be absorbed by the joint, and It is possible to prevent cracks, deformation, and breakage, and improve durability.
【００１６】 図６は他の実施形態を示し、ドリリングタッピングねじとしてのセルフタッピ ングねじ１３を用いて第１と第２のフレ−ム１、２を締め付けたものである。セ ルフタッピングねじ１３は、先端部が鋭利に形成され、下穴を開けることなく、 セルフタッピングねじ１３自身で第１および第２のフレ−ム１、２に下穴を開け ながらねじを立てて締め付けることができ、前記実施形態と同様に第１と第２の フレ−ム１、２を簡単に接合できる。また、ねじ部がフレ−ム自体に食い込むた め、振動等によって緩みにくいという特徴があり、スチ−ルハウス等の骨組等の 構築に有効である。FIG. 6 shows another embodiment, in which the first and second frames 1 and 2 are tightened by using a self-tapping screw 13 as a drilling tapping screw. The tip of the self-tapping screw 13 is sharply formed, and the self-tapping screw 13 itself is used to make a pilot hole while making a pilot hole in the first and second frames 1 and 2 without making a pilot hole. It can be tightened and the first and second frames 1 and 2 can be easily joined as in the above-described embodiment. In addition, since the screw part cuts into the frame itself, it is difficult to loosen due to vibrations, etc., which is effective for constructing frames such as steel houses.
【００１７】 なお、前記実施の形態によれば、第１のフレ−ム１と第２のフレ−ム２との一 端部相互を接合する場合について説明したが、他端部相互の接合においても同様 の構造によって接合することができる。また、タッピングねじ１１およびセルフ タッピングねじ１３の使用する本数もフレ−ムのサイズおよび使用場所によって 適宜変更可能である。さらに、スチ−ルハウスの柱と横桟の接合について説明し たが、スチ−ルハウスに限定されず、フェンス、バリケ−ド等の組立てにも適用 できる。In addition, according to the above-described embodiment, the case where one end portions of the first frame 1 and the second frame 2 are joined to each other has been described. Can be joined by similar structures. Also, the number of tapping screws 11 and self-tapping screws 13 used can be appropriately changed depending on the frame size and the place of use. Further, although the description has been given of the connection between the pillar and the cross rail of the steel house, the invention is not limited to the steel house, and can be applied to the assembly of fences, barricades and the like.
【００１８】[0018]
以上説明したように、この考案によれば、次の効果がある。 例えばスチ−ルハウス等の骨組の構築において、フレ−ム相互を施工現場にお いて簡単に接合でき、接合作業の煩雑さを解消でき、しかも接合部で振動を吸収 ですることができるため、地震等の振動が加わっても接合部の亀裂、変形、折損 を防止でき、耐久性の優れたフレ−ムの接合構造を提供できる。 また、タッピングねじを用いることにより、フレ−ムに下穴のみを設ければよ く、フレ−ムの前加工が容易であり、またタッピングねじは振動等によって緩み にくいという特徴があり、また溶接と異なり、接合部の腐蝕、疲労も少なく、さ らに分解も簡単であることから移動式ハウスなどの骨組等の構築にも有効である 。 As described above, this invention has the following effects. For example, in the construction of a frame such as a steel house, the frames can be easily joined at the construction site, the complexity of the joining work can be eliminated, and vibrations can be absorbed at the joints, so that the earthquake It is possible to prevent cracking, deformation, and breakage of the joint even when vibration such as the above is applied, and to provide a frame joint structure having excellent durability. Also, by using a tapping screw, it is only necessary to provide a pilot hole in the frame, the frame can be easily preprocessed, and the tapping screw is characterized by being difficult to loosen due to vibration and the like. Unlike the above, the joints are less likely to be corroded and fatigued, and the disassembling is easy, so it is also effective for constructing frames such as mobile houses.
