Description

  The present invention relates to a joint between steel plates, for example, a steel frame which is provided at a joint portion between members at the time of processing or assembling, and can easily and firmly join members, and is made of a shape steel, a steel pipe, or the like. The members can be joined together.

  When processing and assembling steel materials, welding and joining bolts are used for joining steel members. As a method of joining steel members by welding, for example, Patent Document 1 discloses an invention of a steel column joint system, and as a method using a joining bolt, for example, Patent Document 2 discloses a method of connecting a column / beam joint of a rigid frame. The invention is disclosed.

  However, the method of joining steel members by welding has problems such as the welding accuracy being greatly affected by the skill and weather of the welder. On the other hand, in bolt joining, bolt hole drilling and bolt nut tightening Since there is work, and torque management of the bolts and nuts is necessary, there are problems such as the work being very troublesome and troublesome.

  The present invention has been made to solve the above problems, and can easily and firmly join members during processing and assembly, and also enables joining of steel members made of shaped steel or steel pipes. The object is to provide a joint between steel plates.

  The present invention is a polygonal steel plate butted against each other, a plurality of steel clips attached to the edge of the steel plate and sandwiching the edge of the steel plate in the direction of the steel plate, A steel fixing ring that is continuously attached to the outer side of the clip in the circumferential direction of the steel plate and fixes each of the clips is provided.

  Here, the steel plate is, for example, a joint end plate attached to each end portion of members to be joined to each other during processing or assembly, and the joint end plate is a quadrangle, hexagon, octagon, or the like. It is formed in a polygonal plate shape, and the joint end plates can be securely and firmly joined to each other by sandwiching the edge portion of the joint end plate with a steel clip. Steel members can be securely and firmly joined to each other.

  In particular, the joint end plates can be securely and firmly joined to each other by attaching each clip in close contact with the straight portion of the joint end plate edge and increasing or decreasing the number of clips as necessary.

  In addition, each steel clip is formed in a groove shape that opens to the side so that it can be attached to the edge of the joint end plate from the lateral direction, and the joint end is formed on the contact surface between the joint end plate and each clip. By providing a taper that is inclined (tapered) in the direction of the tip of the plate, the clip can be easily attached and the edge portion of the joint end plate can be more firmly sandwiched and connected.

  The steel fixing ring has an inner diameter that can be circumscribed on the outer surface of each clip attached to the edge of the joint end plate, and is formed into a ring shape having the same polygon as the joint end plate. A plurality of clips can be firmly restrained and fixed by a single fixing ring.

  Note that the fixing ring can be easily attached to the outside of each clip by sliding the outside of each clip in the abutting direction of the steel plate (joint end plate) (slide in the direction of the arrow in FIG. 1 (a)). At that time, by providing a taper that extends outward of the fixing ring at the inner edge of the fixing ring (see FIG. 1C), the positioning of the fixing ring is facilitated.

  According to the present invention, the steel plate attached to the end of each member to be joined is formed in a polygonal shape such as an octagon, so that the clip that sandwiches the steel plates is attached to the straight portion of the edge of the steel plate. The members can be attached in close contact with each other, so that the members can be securely joined together, and the steel members made of a shape steel, a steel pipe, or the like can be joined firmly.

  Further, by sandwiching the edge portions of the steel plates with a plurality of clips, the steel plates can be joined together more easily and firmly than by welding or bolt joining.

FIG. 1 (a) is a longitudinal sectional view and FIG. 1 (b) is a view in FIG. 1 (a), illustrating a joint between joint end plates provided at a joint between a steel member and a steel member to be joined. Fig. 1 (c) is a cross-sectional view taken along the line of Fig. 1 (b).

  1 (a) to 1 (c) show an embodiment of the present invention, which illustrates a joint between steel plates provided at a joint between steel members. In the figure, joint end plates 3 and 4 are attached to ends of a steel member 1 and a steel member 2, respectively.

  The joint end plates 3 and 4 are formed in a regular octagonal plate shape having the same diameter and the same thickness, the joint end plate 3 is at the end of the steel member 1 in the axial direction, and the joint end plate 4 is the material of the steel member 2. Each is attached to the end in the axial direction by welding.

  Further, the joint end plate 3 and the joint end plate 4 are abutted against each other in the material axis direction of the steel members 1 and 2, and the joint end plate 3 and the joint end plate 3 A steel clip 5 is connected between the joint end plates 3 and 4 with the edge portion of the joint 4 sandwiched between the joint end plate 3 and the joint end plate 4 in the abutting direction (the material axis direction of the steel members 1 and 2). A plurality are attached at intervals in the direction.

  The clip 5 is formed in a groove shape in a side view so as to be attached from the side to the edge portions of the joint end plates 3 and 4 which are abutted. Further, a plurality of clips 5 are attached to the respective straight portions of the edge portions of the joint end plates 3 and 4 at intervals in the circumferential direction of the joint end plates 3 and 4. A fixing ring 6 for restraining and fixing each clip 5 is attached to the outside of the clip 5.

  In addition, a taper is formed on the lower surface 3a of the joint end plate 3 and the upper surface 4a of the joint end plate 4 so as to be inclined (tapered) toward the distal end of the joint end plates 3 and 4, and the taper corresponding to this taper is applied to each clip. 5 are formed on the inner upper surface 5a and the lower surface 5b, respectively, so that the edge portions of the joint end plate 3 and the joint end plate 4 can be sandwiched more firmly (FIG. 1 (c)).

  The fixing ring 6 is formed of a rigid material such as a metal, is formed in the same octagonal ring shape as the joint end plates 3 and 4, and each clip is attached to the edge of the joint end plates 3 and 4. 5 is formed in an octagonal ring shape having an inner diameter that can be circumscribed.

  Since the fixing ring 6 is attached in a state of circumscribing the outside of the clip 5, each clip 5 is strongly pressed against the edge of the joint end plates 3 and 4, whereby the edge of the joint end plates 3 and 4. Never leave.

  The fixing ring 6 can be attached to the outside of each clip 5 by sliding the outside of each clip 5 in the direction of the material axis of the steel members 1 and 2 (in the direction of the arrow in FIG. 1 (a)). Further, by forming a taper 6a that is inclined outwardly on the inner side of the lower end portion of the fixing ring 6, the positioning of the fixing ring 6 is facilitated and attachment is facilitated.

  The present invention can join members easily and firmly at the time of processing and assembly, and can also join steel members made of shaped steel, steel pipes, etc., and has a wide range of application.
