Abstract

PURPOSE:To prevent divergence in a joint part by forming a cavity by a pair of side walls and a joint wall on the jointed members having a same shape and forming an insertion part into both the cavities, on an L-figure-shaped corner member and taper-joining theses members on the outer edge side and inner edge side. CONSTITUTION:A cavity S is formed inside by joint walls 52 and 53 and a side wall 51 in pair with a stay 5, and a tapered surface 55 is formed closely to the outer edge 5a on the inside surface side of the side wall 51, and a tapered surface 56 is formed closely to the inner edge 5b, and a stay 6 is formed to the similar shape. Further, a corner member 7 is formed by arranging the insertion parts 7a and 7b in L-figure form into the cavity S, and the tapered surfaces 71a, 71b, 72a and 72b in parallel proximity are formed through a minute gap on the tapered surface 55 and 56, and after the corner member 7 is inserted into the stays 5 and 6, these members are tightened by bolts 8 and 9. Accordingly, firm jointing is carried out without generating divergence on the joint part through taper joint at two places.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a member joining structure that is applied when joining pipe-shaped members having internal cavities so as to be substantially perpendicular to each other.

[Prior art] Conventionally, as a structure in which pipe-shaped members are joined in an orthogonal state using bolts, an L-shaped corner fitting is interposed at the joining portion of both members, and the corner fitting and each member are connected with bolts. There are known devices that are connected in a tight manner.

[Problems to be Solved by the Invention] However, with just this, there is a problem in that misalignment occurs between the corner fittings and each member, and the joint portions are likely to sway. That is, commonly used mass-produced bolts are manufactured by rolling, so the outer diameter of the root of the head bone is smaller than the outer diameter of the threaded portion. Therefore, the darning bolt only has the function of fixing the corner fitting to the member by surface friction, and cannot play a role like a positioning pin. Therefore, when an external force acts on the joint portion, surface slippage between the corner fitting and each member is likely to occur, and the joint posture is likely to be distorted. Furthermore, when joining both members through corner fittings in this manner, it is difficult to press the joining end surfaces of the members into pressure contact with each other, and gaps often occur between the joining surfaces.

The first and second members each have a pipe shape with a cavity formed inside by a pair of side walls and a pair of connecting walls that connect these side walls, and the joint end faces are arranged in the longitudinal direction. An inwardly tapered outer edge surface that widens toward the inner edge is formed on the inner surface of the both side walls toward the outer edge, and an inner tapered surface is formed on the inner surface of the both side walls toward the inner edge. An inwardly tapered surface on the inner edge side that widens toward the edge side is provided. The corner member is L-shaped and integrally includes first and second insertion portions that are inserted into the cavities of the first and second members, and each insertion portion has a minute inwardly tapered surface on the outer edge side. An outer edge side outward tapered surface that approaches the outer edge side in parallel with a gap therebetween, an inner edge side outward tapered surface that closely contacts the inner edge side inward tapered surface, and a screw hole facing the outer edge side coupling wall are respectively provided. The first bolt passes through the outer edge side connecting wall of the first member and is screwed into the screw hole of the first insertion part of the corner member, and the second bolt passes through the outer edge side connecting wall of the first member. The edge connecting wall is passed through and screwed into the screw hole of the second insertion portion of the corner member. Then, the first insertion portion is pulled toward the outer edge side by the first bolt to bring the outer edge side outward tapered surface of the insertion portion into close contact with the outer edge side inward tapered surface of the first member, and the second insertion portion is pulled by the second bolt. The insertion portion is pulled toward the outer edge to bring the outer edge outwardly tapered surface of the insertion portion into close contact with the outer edge inwardly tapered surface of the second member.

When you want to make sure that the side wall deforms outward smoothly when inserting the outwardly tapered surface on the inner edge side between the inwardly tapered surfaces on the inner edge side using the traction force of the bolt, and that the deformation is not noticeable to the outside. It is recommended that both side walls be curved so that the center part bulges outward.

That is, when a tightening operation is applied to the first bolt, the first insertion portion of the corner member is pulled toward the outer edge of the first member, and the inner edge side outwardly tapered surface becomes the inner edge side inwardly tapered surface of the first member. It will become wedge-shaped in between. That is, in this case, the inner edge side outward tapered surface bites into the inner edge side inward tapered surface while deforming both side walls outward, and the first insertion portion moves toward the outer edge side joining wall while increasing the surface pressure. I will have to move. As a result, the outer edge side outwardly tapered surface also comes into close contact with the corresponding outer edge side inwardly tapered surface. Therefore, the first member and the corner member are connected via two tapered fitting parts,
This results in a strong connection with no wobbling at all. Similarly, when a tightening operation is applied to the second bolt, the inner edge side outward tapered surface of the second insertion portion bites into the inner edge side inward tapered surface while deforming both side walls of the second member outward. Therefore, the second insertion portion moves toward the outer edge side joining wall while increasing its surface pressure. As a result, the outer edge side outwardly tapered surface also comes into close contact with the corresponding outer edge side inwardly tapered surface. Therefore, the second member and the corner member are also connected via two tapered fitting parts,
This results in a strong connection with no wobbling at all.

In addition, with such a configuration, by tightening the first bolt, the first member is relatively drawn toward the corner member, and by tightening the second bolt, the second member is pulled toward the corner member. It will be relatively drawn towards the corner member. Therefore, by tightening both bolts, it becomes possible to press the joining end surfaces of the first and second members into pressure contact with each other, and it is possible to join both members without any gaps.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to accurately position and strongly connect the first and second members so that they do not loosen. It is possible to provide a member joining structure in which an excellent joining state with no gaps can be obtained by bringing joining surfaces into pressure contact with each other. In particular, in this joint structure, the first and second members and the corner member are
Since they are tapered together at two locations, one on the outer edge and one on the inner edge, even if torsional force or the like is applied to the first and second members, problems such as discrepancies in the joints may occur. can be effectively prevented.
