Description

    TECHNICAL FIELD
  • The present invention relates to connecting metals suitable for wooden buildings.
  • BACKGROUND ART
  • The Great Hanshin-Awaji Earthquake has made us recognize the importance of connecting metals in wooden buildings as a means for securing the safety of wooden buildings, and has caused us to implement well-balanced installation of load-bearing walls. Resistance of the load-bearing walls is added up by column capitals and column bases provided alongside the load-bearing walls. For exertion of sufficient resistance of the load-bearing walls, joints with these column capitals and column bases are crucially important and require connecting metals that are suitable for the type and location of the load-bearing walls.
  • In order to secure horizontal diaphragm stiffness and strength performance at column-to-beam joints in a wooden building, the Applicant has proposed a connecting metal for use at a column-to-beam joint with a load-bearing wall, for example, as disclosed in PTL 1.
  • This connecting metal is composed of a steel plate and a steel tenon pipe that are integrated in a racket-like shape by welding or the like. The plate is inserted in a slit formed in each of an upper end and a lower end of a column, and joined with the column by drift pins inserted from a side surface of the column. The tenon pipe is inserted in a mortise formed in a beam, and is joined with a beam member by drift pins inserted from a side surface of the beam. This connecting metal can sufficiently absorb the energy of earthquakes against a pullout force exerted on the column at each side of the high-stiffness wall surface.

  • SUMMARY OF INVENTION Technical Problem
  • In the above-described configuration, each mortise in the beam is typically designed in the substantially same diameter as the tenon pipe, with almost no clearance between the mortise and the tenon pipe inserted therein, in order to secure the stiffness of the beam. At the same time, the connecting metal requires a weld leg length and a weld throat thickness having predetermined dimensions at a welded portion of the tenon pipe and the plate, in order to secure sufficient strength of the connecting metal. For the joint between thin plate materials like the plate and the tenon pipe, however, it is relatively difficult to secure the leg length and the throat thickness having predetermined dimensions. Even when the predetermined dimensions can be secured, weld reinforcement may protrude from a surface of the welded portion and may interfere with the internal surface of the mortise, thereby preventing insertion of the tenon pipe into the mortise or causing a crack in the mortise.
  • To cope with the case where weld reinforcement protrudes out of the outer periphery of the tenon pipe, the welded portion needs manual sanding to be level with the outer periphery of the tenon pipe so as not to interfere with the internal surface of the mortise. Such sanding requires additional manual labor, sacrifices production efficiency, and may even impair a required strength if an unskilled worker grinds the welded portion too much.
  • The present invention is made in view of these circumstances, and aims to provide a connecting metal that is configured to secure a required strength at a joint between the tenon pipe and the plate of the connecting metal where a considerable pullout resistance is required, and that is configured to prevent weld reinforcement at the joint from interfering with the mortise, thereby enhancing production efficiency and work efficiency.
  • Solution to Problem
  • As a means for realizing the above-mentioned object, the present invention provides a connecting metal that includes a tenon pipe having at least one through-hole for fixing the tenon pipe by a drift pin or a bolt, and a plate joined at an end of the tenon pipe and having at least one through-hole for fixing the plate by a drift pin or a bolt, the tenon pipe and the plate being joined with each other in a substantially racket-like shape, wherein a pair of slits for receiving the plate is formed at the end of the tenon pipe, each of the slits being defined by a first side edge and a second side edge that are bent inwardly, and the plate is inserted in the pair of slits and joined with the tenon pipe by welding, with no protrusion of weld reinforcement out of an outer periphery of the tenon pipe.
  • Since the first and second side edges of the slits in the tenon pipe are bent inwardly, this configuration enables welding of the tenon pipe and the plate while securing a weld leg length and a weld throat thickness having predetermined dimensions and preventing protrusion of weld reinforcement out of the outer periphery of the tenon pipe. This configuration can eventually enhance production efficiency of the connecting metal and work efficiency in joint work using the connecting metal.
  • Advantageous Effects of Invention
  • The connecting metal according to the present invention having the above-described configuration can have the tenon pipe and the plate welded together while securing a required strength at a joint therebetween and preventing weld reinforcement at the joint from interfering with the mortise. This connecting metal no longer requires manual sanding, and eventually enhances production efficiency and construction work efficiency.

  • FIG. 2 is a sectional view of the connecting metal, taken along the line A-A in FIG. 1 .
  • FIG. 3 illustrates a manner of joining a plate and a tenon pipe of the connecting metal.
  • FIG. 4 a is a top view of the tenon pipe, and FIG. 4 b is a side view of the tenon pipe.
  • FIG. 5 is a sectional view showing an example of a joint structure using the connecting metals according to the embodiment of the present invention.
  • DESCRIPTION OF EMBODIMENTS
  • A connecting metal according to an embodiment of the present invention is now described with reference to the drawings.
  • FIGS. 1 to 5 show the connecting metal according to the embodiment of the present invention. For clarity, cross sections of the members shown in FIG. 5 are illustrated without hatching.
  • The connecting metal 1 according to the embodiment includes a steel plate 12 and a steel tenon pipe 13. The plate 12 has an insertion piece 121 to be inserted in a first end of the tenon pipe 13. The plate 12 and the tenon pipe 13 are integrally joined in a racket-like shape by welding.
  • The plate 12 and the tenon pipe 13 have a plurality of through- holes 122, 132, respectively, for fixing the plate 12 and the tenon pipe 13 on a column and a beam by drift pins or bolts. In the illustrated embodiment, the plate 12 has two through-holes 122 that are formed side by side and adapted to be fixed by two drift pins. Likewise, the tenon pipe 13 has two through-holes 132 that are formed in the same penetration direction as the through-holes 122 in the plate 12.
  • As shown in FIG. 4 b , a pair of slits 131 for receiving the plate 12 is formed at the first end of the tenon pipe 13. The width of the slits 131 is substantially identical to the thickness of the plate. In the illustrated connecting metal 1, the plate thickness and the slit width are 3.2 mm each. The length of the slits corresponds to the length of the insertion piece 121 of the plate 12.
  • As shown in FIG. 4 a , side edges of the slits 131 are processed to bend inwardly toward an axis of the tenon pipe 13. The thus processed slit areas of the tenon pipe 13 provide channels that are indented relative to the outer periphery of the tenon pipe 13.
  • To form the connecting metal 1, the insertion piece 121 of the plate 12 is inserted in the slits 131 of the tenon pipe 13 and joined with the tenon pipe 13 by flare welding. Since the slits 131 are processed to bend inwardly, the slits 131 and the insertion piece 121 inserted therein can form substantially V-shaped grooves therebetween. Welded portions 133 between the plate 12 and the tenon pipe 13 allow weld metal to penetrate in these inwardly bent portions, while keeping a throat thickness of a predetermined dimension and preventing protrusion of weld reinforcement out of the outer periphery of the tenon pipe 13.
  • As also illustrated, a second end of the tenon pipe 13 is formed as a lap portion 14 having a semicircular cross section. An extremity of the tenon pipe 13 is halved to provide the lap portion 14. A flat plate member is welded on the lap portion 14, and the through-holes 132 are formed in this plate member. Welding of the lap portion 14 and the plate member are also performed with no protrusion of weld reinforcement out of the outer periphery of the tenon pipe 13. The resulting lap portion 14 can be overlapped on a lap portion 14 formed in a tenon pipe 13 of another connecting metal 1.
  • For the connecting metal 1 according to the present invention, the basic size of the plate 12 corresponds to a substantial square whose width is nearly equal to a side column, and the width of the plate 12 is preferably increased or decreased in accordance with the number of through-holes formed in the plate 12. Preferably, the length of the tenon pipe 13, the number of through-holes formed in the plate 12, and the number of through-holes formed in the tenon pipe 13 are set appropriately in accordance with a required pullout resistance. Additionally, instead of one tenon pipe 13, two tenon pipes 13 aligned in the same direction may be joined with the plate 12.
  • The connecting metals 1 having the above configuration may be used, for example, with column-to-beam joints as shown in FIG. 5 . In the illustrated embodiment, the plates 12 of the connecting metals 1 are inserted in slits 21 formed in column capitals and column bases of columns 2. The plates 12 are connected with the columns 2 by drift pins 5 inserted in the through-holes 122 from side surfaces of the columns 2. The tenon pipes 13 of the connecting metals 1 are inserted in mortises 31 formed in a beam 3, and are connected with the beam 3 by drift pins 5 inserted in the through-holes 132 from a side surface of the beam 3. The tenon pipes 13 can be smoothly inserted in the mortises 31 without interference. These connecting metals 1, each having a required strength, can achieve a structure that satisfies strength performance of the joints.
  • As described above, the connecting metal 1 according to the present invention can be manufactured by the welding of the plate 12 and the tenon pipe 13, while keeping a required strength at the welded portions 133 where it is relatively difficult to secure the leg length and the throat thickness having predetermined dimensions, with no protrusion of weld reinforcement out of the outer periphery of the tenon pipe 13. As a result, the connecting metal 1 no longer suffers from interference of weld reinforcement at the welded portions 133 with the mortise 31, and no longer requires manual sanding, thereby enhancing production efficiency and work efficiency.
  • The present invention can be embodied and practiced in other different forms without departing from the spirit and essential characteristics of the present invention. Therefore, the above-described embodiment is considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claim rather than by the foregoing description. All variations and modifications falling within the equivalency range of the appended claim are intended to be embraced therein.
  • INDUSTRIAL APPLICABILITY
  • The connecting metal according to the present invention is suitably used to satisfy strength performance at joints including connections of column capitals and column bases alongside high-stiffness load-bearing walls in a wooden building, and can accomplish an earthquake-resistant construction method by reinforcing a principal part for structural resistance.
