一致させる必要があり、施工性に難点がある。 The above-mentioned conventional problems are due to the use of exterior material as the joint member, so an inner member is used as the joint member, and the inner joint member is pressed and spread to tightly join it to the pipe material. The invention described in JP-A-53-53118, U.S. Pat.
The idea described in the publication has been proposed, but
The invention described in JP-A-53118 has a problem in workability because it is necessary to match the bolt hole of the joint member and the bolt hole of the joint end of the pipe material during construction.

であるパイプ材の接合構造にある。(Configuration for Achieving the Purpose) The present invention uses an inner member as a joint member, and when the inner joint member is pressed and expanded to tightly join with a pipe material, it is possible to use an insert member as a bolt insertion part of the joint member. By using a slit opening, problems with workability are solved, and the joint member of the pipe member is tightened by the interaction between the bolt member and the internal nut, while the inner joint member is pressed and spread to fit tightly with the pipe material. It is a structure in which a pair of pipe materials 2, 2 are joined in the longitudinal direction or the pipe material 2 is joined perpendicularly to the support 1, and the joint end of the pipe material 2 is It consists of a joint member 3 that is inserted into the pipe member 2 and an external bolt member 4 that fixes the member to the pipe member 2. The joint member 3 has a cylindrical portion that is inserted into the pipe member 2, and extends over its entire length in the longitudinal direction. The bolt member 4 has a slit opening 31, and the tip of the bolt member 4 is inserted into the pipe member through the lower bolt hole 21 or the like.
An internal nut 5 extending in the width direction of the slit opening 31 is screwed inside the joint member through the slit opening 31 of the joint member 3, and the bolt member 4 is threaded so that its tip is inserted into the joint member. 3 and press the joint member 3 against the inner surface of the pipe material 2. At the same time, the internal nut 5 screwed into the bolt member is screwed back to press the vicinity of the slit opening 31 of the joint member 3. This is a joining structure for pipe materials that can be joined by pushing the joint member 3 into close contact with the pipe material 2 by pushing it apart.

ないように行われる。 Specifically, as shown in FIG.
When joining them in the longitudinal direction, as shown in Fig. 1, the bottom part of a pipe material of a similar shape that can be inserted into the square or circular pipe material 2 is cut out over the entire length, and a slit is formed as the joint member 3. As shown in FIG.
1 is inserted between the nut 5 and the inner surface of the pipe material 2, and when the bolt 4 is tightened as shown in FIG. While abutting and pressing the joint member 3 against the inner surface of the pipe material 2, the nut 5 screwed onto the bolt is screwed back and abuts near the full-length opening 31 of the joint member 3, enlarging the opening 31. The joint member 3 is a pipe material 2
This allows the pipe materials to be joined without blur.

ましい。 The pipe material 2 may be provided with a notched groove at the joint end instead of having the bolt hole 21 formed therein. In this case, if a hexagon socket head bolt is used as the bolt 4, the pipe material 2 can be inserted through the notch groove and opening 31.
The design can be improved by housing the bolt head inside. Further, it is preferable to use a taper nut as the nut 5 so that the tapered surface thereof comes into contact with the inner surface near the opening 31 of the joint member 3 because it is easier to enlarge the opening 31 of the joint member 3.

には同一番号を付して説明を省略する。 On the other hand, as shown in FIG. 5, when joining the pipe material 2 orthogonally to the support 1, the joint member 3 is a pipe material having an opening 31 as shown in FIGS. 6 and 7. 2 corresponding shape portion 32
Abutment part 33 with the pillar hanging perpendicularly from one end
Use a member with In this case, in order to spread out the ends 34 forming the opening 31, it is necessary to separate the ends 34 from the abutting portion 33. The manner of joining is similar to the joining of pipe materials shown in FIG. 3, so the same parts are given the same numbers and the explanation will be omitted.

ト締め強度を得ることができる。(Operation and Effect of the Invention) As is clear from the above explanation, according to the present invention, when joining a pair of pipe materials 2, 2 in the longitudinal direction or joining the pipe material 2 to the support 1 in the orthogonal direction, the pipe material 2 is used as the joint member, and bolts and nuts are installed through the opening 31 that extends over the entire length of the joint member, so the dimensional accuracy in construction is improved by matching the bolt holes as in the conventional method. This improves workability as it can be installed without the need for bolts, and most, if necessary, all of the bolts and nuts can be housed within the pipe material, so bolt tightening strength can be obtained without compromising the design. I can do it.

ことができる。 Moreover, the tip of the bolt 4 is brought into contact with the upper inner surface of the joint member 3, and the joint member 3 is pressed against the inner surface of the pipe material 2, while the nut 5 screwed onto the bolt is inserted into the full-length opening 3 of the joint member 3.
1 and enlarged, and the joint member 3 is brought into close contact with the pipe material 2 and joined, so that the joint member 3 can be firmly joined without wobbling at the joined part.
