が多く採用される。2. Description of the Related Art For example, in a stairwell, a high wall surface of a curtain wall system is sometimes supported by an upright pillar on the indoor side. If this pillar is made of one type of steel material, it becomes thick and heavy, and the atmosphere of the hall becomes heavy and heavy when viewed from the inside of the hole.However, if it is a truss marion, which is a flat truss structure combining thin steel materials, Can be configured to feel. In addition, a space truss structure is often used as a large-area lightweight roof structure having no support inside.

さの調節をできない構造となっている。[0003] Such a flat truss structure and a space truss structure are formed such that struts form oblique triangles between two steel members (long members) arranged in parallel or between a plurality of node members arranged in a space. Although they are combined into a single structural member, they are often assembled on site for transport reasons. However, in the conventional strut, a joint p for connecting to a long material or a node member is directly bolted to the rod q with a bolt r (FIG. 6), or a long female screw rod s inserted into the rod is attached to a bolt r. (FIG. 7), and the length cannot be adjusted originally.

で長さの調整を必要とする。In the structure shown in FIG. 6, a slight adjustment can be forcibly performed by adjusting the tightening amount of the bolt r. However, particularly when the rod q is formed of a relatively soft material such as an aluminum alloy, if the screwed portion is repeatedly rotated for adjustment at the time of assembling, the rod q is likely to be loosened. It is not preferable from the viewpoint of maintaining strength. In the configuration of FIG. 7, if a steel material is used for the female screw rod s, the problem on the material can be solved. However, this structure does not allow any length adjustment. The strut may be used alone as a brace or a bundle, and in such a case, the length must be adjusted on site.

If this is forcibly assembled, the truss structure member is twisted or the connection portion is easily broken, leaving internal stress in the long member, the strut, the node member, or the connecting portion of these members, thereby easily causing troubles.

挟めるようにフォーク形になっていることが多い。A joint, an adjusting member, a stud, and a rod are arranged along one central axis, and these are integrated into a strut by screw connection. The joint is a member that connects the adjusting member with the receiving member attached to the long member or the node member connected by the strut. One end has a connecting portion with the receiving member, and the other end has a cylindrical shape that receives the male screw portion of the adjusting member. Female thread. The connecting portion is often forked so that the receiving portion of the receiving material can be sandwiched from both sides.

The pitch of the male thread is greater than the pitch of the female thread and the direction of the threads is the same. The stud has an operating part in the center,
The male screw part protrudes on both sides. The male screw at one end is for screwing with the female screw of the adjusting bolt, and the male screw at the other end is for screwing with a female screw provided at the end of the rod. The pitch between the external threads on both sides and the direction of the threads may be the same or different. The rod is made of an extruded aluminum alloy and has an axial internal thread at least at one end. Most are cylindrical, but sometimes solid.

The outer shape of the part may be made to match the outer shape of the rod, and the strut made of these members may be made to have an appearance made of a single rod as a whole. That is, the members are unified so that the outer shape of the members is a single strut. In this manner, the strut has decorativeness, and is suitable for use as, for example, a truss marion component for supporting a curtain wall of a hall indoors.

And assemble. That is, at least at one end of the rod, one of the male threads of the stud is screwed into the female thread of the rod, and the stud is attached to the rod, and the male thread of the adjusting member is screwed into the female thread of the joint, A structure is provided in which the other male thread of the stud is screwed into the female thread of the adjusting member.

する。The struts are used as follows. By turning the adjusting member, the entire length of the strut is made to substantially correspond to the distance between the receiving members (fixed to the long member and the node member) to be attached. One end of the strut is attached to one receiving member via a joint, and the other end is similarly attached to the other receiving member. When attaching the other end, the adjusting member is rotated so that the joint of the joint and the receiving member almost completely coincides with each other. By rotating the adjusting member to adjust the length of the strut, the play between the both end connecting portions of the strut and the both-side receiving members is eliminated.

る。When the adjusting member is turned, the external thread portion on the outer surface is screwed into the female thread portion of the joint, and at the same time, the female thread portion comes off from the stud (when the thread direction is the same for all the thread portions). However, since the pitch of the male thread is larger than the pitch of the female thread, the length of the lattice member is reduced by the difference. The length of the adjustable length is mainly determined by the length of the external thread on the outer surface of the adjusting member. The directions of the threads of the male and female threads of the adjustment member may be different. In this case, when the adjusting member is rotated, the length of the strut expands and contracts by the sum of the pitch of the male screw portion and the pitch of the female screw portion.

様の説明となる。Further, the adjusting member 8 is attached and adjusted at the time of adjustment.
Is rotated, there is no relative movement between the rod 5 and the stud 9, which are often made of an aluminum alloy or the like, and there is no loosening from this part. In FIG. 1, reference numeral 26 denotes a set bolt, which is used to prevent loosening of each screw portion in a state where play between the strut 4 and the column 3 (a, b) is absorbed. In the above, the truss mullions of the plane truss structure using the struts between the two columns arranged side by side have been described. However, the description about the three-dimensional truss structure in which the nodal members arranged in the space are connected by the struts is almost the same.

部分的な破断を防止することができる。According to the structure of the first aspect, since the length of the strut can be adjusted, it is easy to assemble the flat or three-dimensional truss structural member. When the strut is used for bracing and bundling on site, the length can be adjusted, so it is easy to use. Since the length of the strut can be adjusted, the structural member using the strut can evenly disperse the internal stress and prevent torsion and partial breakage.

According to the configuration of the second and third aspects, it is possible to obtain a structural member free of twist and play. In addition, since the internal stress can be evenly dispersed, partial breakage does not occur after assembly.
