Field of the Invention The present invention relates to a joint attachment mechanism for pipes made of all kinds of materials such as steel pipes, aluminum metal pipes, and reinforced plastic pipes such as FRP. In detail, without using the welding means and the joining means such as flange joints that have been conventionally adopted,
Further, the present invention relates to a pipe joint mounting mechanism capable of performing safe and reliable joint mounting of pipes in a short time without requiring any special technique.

採用されていた。2. Description of the Related Art Conventionally, in a metal structure represented by a building, a bridge, a steel tower, a highway, etc., a large number of columnar steel pipes and prismatic steel pipes have been used as column members, and the joint portions of these column members are joined together. For attachment, a method of joining attachment by welding work or joining attachment by a flange joint was adopted at the enforcement site instead of at the factory for the reason of material transportation.

【発明が解決しようとする課題】しかるに、まず溶接作
業による接合取付けの方法には、つぎのような問題点が
あった。 この溶接作業は天候の影響を受け易いため、強風の日
や雨天の日には現場溶接が困難となることが多い。 溶接作業を行うには、フラックスの垂れ落ち等の理由
から下向き姿勢による溶接が最も良好な条件であるが、
現場溶接では必ずしもこの条件を確保することができ
ず、上向きや横向き等の無理な姿勢による溶接作業を余
儀なくされることが多かった。However, the method of joining and attaching by welding work has the following problems. Since this welding operation is easily affected by the weather, it is often difficult to perform on-site welding on a strong wind day or a rainy day. In order to perform welding work, welding in a downward position is the best condition for reasons such as dripping of flux, but
In-situ welding cannot always ensure this condition, and it is often necessary to perform welding work in an unreasonable posture such as facing up or sideways.

業に要する時間が多くかかり、そのことが工期に悪影響

あるが、溶接技術者を手配するのに苦労することが多か
った。After the welding work, a quality inspection of the welded portion was required by an experienced qualified person, but no one can perform this quality inspection, so it is difficult to arrange a qualified person. There was an occasion. Compared with the joining method by bolt joining, it takes much time for joining and mounting work, which adversely affects the construction period. It is necessary to secure a welding technician for each enforcement site, but it was often difficult to arrange a welding technician.
【０００５】さらに、高力ボルトを使用したフランジ継
手による接合取付けの方法にあっては、つぎのような問
題点があった。 フランジ継手では、フランジ部の板厚を母材の板厚の
３〜５倍程度必要とし、そのために鋼材の使用量が増
え、コスト増につながる。 高力ボルト接合するために、フランジ部が管体よりも
外側に大きく突出することになり、外観の体裁や仕上げ
材の取付けに際し不都合なことが多い。 施工に際しては、高力ボルト締結時の、軸力管理を行
う必要がある。 高力ボルトに繰り返し応力がかかるため、高力ボルト
の疲労破壊に対する配慮が必要となる。Further, the method of joining and mounting by the flange joint using the high strength bolt has the following problems. In a flange joint, the plate thickness of the flange portion is required to be about 3 to 5 times the plate thickness of the base material, which increases the amount of steel used and leads to an increase in cost. Since the high-strength bolts are joined, the flange portion protrudes to the outside more than the tubular body, which is often inconvenient for the appearance and mounting of the finishing material. At the time of construction, it is necessary to manage the axial force when fastening the high-strength bolt. Since high-strength bolts are repeatedly stressed, consideration must be given to fatigue failure of high-strength bolts.

のすべての問題点を解消しようとするものである。The present invention does not require welding work or joining work with a flange joint, which involves the above-mentioned problems, and simply and reliably joins and attaches pipes by using joint parts produced in advance in a factory. By doing so, it is intended to solve all the above problems.

ことを特徴とする管体の接合取付け機構である。Therefore, according to the present invention, a pair of joining members each having a projecting ridge portion similar to a screw thread on the outer surface thereof are provided at both joint end positions of a pipe body to be joined. A tubular meshing member, which is fixed or integrally formed and is in close contact with the convex mountain portion from the outer surface side of the joining member, is arranged on the outer surface side of the joining member. A cylinder that divides the member into at least two parts and has a concave trough on the inner surface thereof, and further forms an outer surface of the meshing member into a tapered surface so that the meshing member can be pressed into contact with the outer surface. The tubular jacket member is arranged on the outer surface side of the meshing member, and the inner surface of the tubular jacket member is formed into a tapered surface.

凸状山部に、噛合部材の内表面に形成した凹状谷部を噛

に分割してある噛合部材を突き合わせて、完全な筒状体
に組み立てる。According to the present invention, the convex crests formed on the outer surface of the joining member are pressed against each other while the concave troughs formed on the inner surface of the engaging member are engaged with each other. The divided mating members are butted and assembled into a complete tubular body.
【０００９】このため接合取付けの対象となる管体の両
接合端部に位置する接合部材は、凸状山部と凹状谷部と
を介して噛合部材により左右に分離不可能な状態に保持
される。For this reason, the joint members located at both joint ends of the pipe body to be jointed and attached are held in an inseparable left and right state by the meshing member via the convex peaks and concave troughs. It

はあるが一応筒状体に組み立てられており、このままで

状形状を安定保持させるために、その外表面側に押さえ
として筒状ジャケット部材を被せることになる。At this time, the engagement member itself is temporarily assembled into a tubular body, but the tubular body is easily collapsed as it is, so that the tubular shape is stably maintained. Therefore, the outer jacket side is covered with a tubular jacket member as a retainer.

面を圧接緊締された状態で安定的に保持される。Since the outer surface of the meshing member and the inner surface of the tubular jacket member are both tapered surfaces, when the tubular jacket is gradually brought into pressure contact with the meshing member from the side, finally, Both members are fixed so as not to loosen easily, and as a result, even if the meshing member is formed of a divided body, the outer surface of the meshing member is stably held with the outer surface pressed and tightened.
【００１２】このため、本発明の接合取付け機構は、簡

Fig. 3 is a side view of the same, Fig. 3 is an exploded perspective view, and reference numerals 1a and 1b are hollow tubular bodies having an appropriate shape such as a columnar shape or a prismatic shape. The joining members are provided at both joining end positions of the tubular bodies 1a and 1b. 2a, 2b
Are fixed or integrally formed. In the case of fixing, the joint between the joint end and the pipe body is fixed by welding means or the like, but since the work is carried out in the factory before the on-site delivery of the pipe body, the above-mentioned inconvenience does not occur. Reference numeral 3 is a backing necessary for welding work, and 4 is a welded portion.

The shape of the convex ridge portion 5 is one continuous spiral shape, Alternatively, it is possible to freely select a method of repeatedly forming a plurality of discontinuous protruding brackets.

ことができる。Next, a shape corresponding to the shape of the convex crest 5 is formed on the inner surface of the cylindrical engaging member 6 which is in a relationship of covering the convex crest 5 from the outer surface side of the joining members 2a and 2b. The concave valley portion 7 is recessed. If necessary, the convex crests 5 and the concave troughs 7 may have different pitch dimensions, so that the meshing relationship between the two can be gradually enhanced.

実に行うことができる。The meshing member 6 is divided into two parts (may be divided into three parts, four parts, etc.) at a horizontal cross-section position in the drawing, and they are joined in a split mold state in which they are divided. There is no problem in covering the member so as to apply it from the surroundings, whereby the convex crests and the concave troughs can be reliably engaged.
【００１７】さらにこの噛合部材６の外表面は、片勾配

するようにかぶせる。As described above, with the engagement member 6 securely covered with the joining members 2a, 2b, the tubular jacket member 8 previously inserted through the tube and loosely fitted is slid to the outer surface position of the engagement member. Then, the upper surface of the meshing member is covered so as to come into pressure contact therewith.

完了する。At this time, since the inner surface of the tubular jacket member is formed into the tapered surface 8a, when the end portion of the tubular jacket member 8 is tapped slowly, the tubular jacket member causes the meshing member to come from the outer surface side. Tightening is performed while press-fitting, and the attachment of the joint attachment mechanism of the present invention is completed.
