BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the general field of construction structures, and mainly relates to a joining element for joining a space truss structure and a base material surrounding the outer periphery thereof for mounting a finishing material.

[0002]

2. Description of the Related Art A three-dimensional truss structure composed of nodal members, chords and diagonal members is excellent in strength for its light weight, and has a large span structure and various curved surface constructions, and can be used for roofs and tensions of buildings. Used as a structure to support walls. When surrounding the outer periphery of this space truss structure with a finishing material, all the base materials for attaching the finishing material must be joined on the node members of the space truss structure, however, the node member depends on the manufacturer who manufactures it. In addition to having different shapes, there are various types even within the same manufacturer, depending on the loads that the nodes bear and the shapes of the constituent surfaces. Further, the base material is selected in various shapes depending on the required strength and the method of attaching the finishing material. Therefore, the joining element that joins the nodal member and the base material for mounting the finishing material must be designed and manufactured each time if either one of them is different, and the base material for the curved surface is the nodal part. Requires subtle angle adjustment,
The number of joining parts has increased and the joining work has required a lot of labor and cost.

[0003]

In view of the above, the present invention has been made in view of the above problems.
Provides a joining element that has a simple structure and can be used to join various node members to the base material for mounting the finishing material, and that can adjust the angle and position of the base material at the nodes even when forming a curved surface. To do.

According to the joining element of the present invention, a guide groove of a bolt head is formed in the outer peripheral portion of a disk body having a required diameter and a required thickness, and the guide element is communicated with the guide groove and opened to the outer peripheral surface. A joint formed by arranging a screw shaft guide groove laterally in a T shape, connecting the bolt head insertion hole to the bolt head guide groove, and vertically installing a through hole for bolt insertion in the central portion. With the bracket body,
The fastener includes one surface having a through hole connected to the outer peripheral surface of the joining metal body and the other surface having a through hole joined at a right angle to the one surface. Here, the fastener is one in which one surface is flat, and one in which a washer having a bonding surface having the same curvature as the outer peripheral surface of the metal fitting body is interposed in the one surface, and one surface and the other surface are integrally bonded. From those that are joined, those that are joined to each other so as to be swingable about a horizontal axis are also included.

[0005]

[Operation] The guide groove of the bolt head and the screw shaft guide groove of the joining metal fitting body guides the bolt shaft center to an arbitrary position on the outer peripheral surface, and the through hole vertically provided in the center allows the fitting metal fitting body to be adjusted vertically as a nodal member. A bolt for coupling to the fastener is inserted and guided, and a through hole formed in one surface of the fastener is inserted into a bolt that swingably couples the fastener to the joining metal fitting body in a direction orthogonal to the longitudinal direction of the base material. The through-holes formed through the other surface allow bolts that connect the fastener to the base material so that the fastener can be swung up and down in the longitudinal direction of the base material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment. As shown in FIG. 2, the fitting main body 1 has a recessed hole 2 formed in the center of a disk body having a required diameter and a required thickness. A through hole 3 is vertically provided at the center of 2, and a bolt 17 is horizontal on the peripheral wall 4 and the screw shaft shaft end is projected from the outer peripheral surface to form 360 °.
A guide groove 5 of the bolt head for guiding and a screw shaft guide groove 6 communicating with the guide groove 5 and opening to the outer peripheral surface are provided around the guide groove 5 of the bolt head from the side of the recessed hole 2. It is formed by connecting the through holes 7 of the bolt head, while the fastener 8
As shown in FIG. 3, one surface 9 is
The other longitudinally long vertical surface 10 is integrally joined to one end portion in the front-rear direction, and a through hole 11 is provided in the horizontal direction at the center of the upper portion of each of the both surfaces. On the joining side, the joining surface 12 has the same curvature surface as the outer peripheral surface of the joining fitting body 1, and a washer 13 having a through hole 11 arranged in the horizontal direction is interposed in the central portion.

As shown in FIG. 1, the joint element thus constructed is a nodal member 14 of a space truss structure as an example.
The joining metal fitting body 1 is joined to the top of the nut 1, that is, the nut 15 is attached from above and below the through hole 3 to the bolt 15 standing on the top, as indicated by the phantom line in FIG.
6 is used to join the joining metal body 1 so that the height thereof can be freely adjusted.

As shown in FIG. 1, the required number of bolts 17 (as many as the number of base materials 19) are inserted through the insertion holes 7 of the bolt head into the joining metal fitting body 1 joined to the nodal members 14 in this manner. While guiding the bolt head to the guide groove 5 of the bolt head, the screw shaft of the bolt 17 is guided to the screw shaft guide groove 6
Position the bolt 17 at the required position by projecting further,
In this state, one surface 9 of the fastener 8 is fastened to each bolt 17 with the nut 18 with the washer 13 interposed. Next, each base material 19 is joined to the other surface 10 of each fastener 8 through the through hole 11 with a bolt and a nut.

Therefore, even if the number of base materials 19 increases or decreases, it is possible to respond promptly by increasing or decreasing the numbers of fasteners 8 and bolts 17, and no matter what angle the mounting crossing angle θ of the base materials 19 intersects. By moving the bolts 17 on the joining metal fitting body 1, the positioning of the fastener 8 can be easily adjusted immediately to the joining position of the target base material 19, and the fastener can be prevented from tilting vertically in the longitudinal direction of the base material 19. Other side 1 of 8
The joining posture is adjusted at the screw shaft of the bolt inserted into the through hole 11 at 0, and further, with respect to the inclination of the base material 19 in the direction orthogonal to the longitudinal direction, the fastener 8 is inserted into the through hole 11 on the one surface 9 of the fastener 8. The joint posture is adjusted at the screw shaft of the bolt 17, and the height of the entire base material 19 is adjusted by adjusting the height position of the joint metal body 1 with the nut 16 with respect to the bolt 15 standing on the node member 14. To be done.

In the fastener 8 of the present invention, as shown in FIG. 4, one surface 9 to be joined to the fitting main body 1 is a front surface and the other surface 10 to which the base material 19 is joined is a horizontal surface. There is also provided one that is swingably engaged to the left and right via a more drooping leg 20.

[0011]

[Effects of the Invention] As described above, the joining element of the present invention, when joining a node member and a base material for mounting a finishing material in a three-dimensional truss structure, increases or decreases the number of base materials and follows the crossing angle of the base material. Since the height of the entire base material can be adjusted, the vertical inclination of each base material can be adjusted in the longitudinal direction, the vertical inclination of the base material can be adjusted in the direction orthogonal to the longitudinal direction, and the structure is simple, a skilled worker can be used. There is an effect that the welding work can be extremely labor-saving without requiring it.
