ものとなり、これが施工能率低下の原因の一つとなって
いた。Conventionally, when joining a beam and a joist, a bolt or nut is used, the bolt is inserted through the flange of the beam and the flange of the joist, and then the nut is screwed onto the insertion bolt. However, inserting bolts and threading and tightening nuts into a large number of joists requires a lot of effort, and this reduces construction efficiency. This was one of the causes.

更に、振動等によりナツトが弛み、快適居住性を阻害す
る床鳴り（キシミ音）の原因ともなっていた。Furthermore, the nuts loosen due to vibrations, etc., causing floor rumbling (squeaking noise) that impairs comfortable living.

とはできない。Furthermore, as a joining means that does not use bolts as described above, as shown in Japanese Utility Model Publication No. 57-60408, a coupling tool having elastic protrusions protruding from the inner surfaces of three opposing pieces of a clamping piece is used. A technique is also known in which the framework is joined by sandwiching it between the overlapping parts of parallel beams and purlins that overlap vertically, but this conventional technique cannot connect the overlapping parts of orthogonal beams and joists.

本考案は、かかる実情に鑑みて、直交する姿勢で重合す

床鳴りを発生させない確実な接合の強度を保持する接合
用金具を提供せんとするものである。In view of these circumstances, the present invention allows for quick and easy joining of beams and joists that overlap in orthogonal positions, and
It is an object of the present invention to provide a joining metal fitting that maintains reliable joining strength that does not cause floor noise.

特徴とする特 これによれば、直交する梁と根太の対接面フランジ部の
重合部に対して、この金具を弾性抵抗に抗して打込むだ
けの極めて簡単な作業で根太と梁とを接合できる。The metal fitting for joining a joist to a beam according to the present invention has a clamping piece that presses the flange of the beam from the bottom side, a clamping piece that presses the flange of the joist from the top side, and a clamping piece that connects both clamping pieces. It is composed of a member formed into a U-shape or almost a U-shape when viewed from the side by three opposing pieces and a web part, and further, the clamping piece that presses the flange part of the joist has the U-shape. or projecting outward in the left and right direction from the left and right side edges of the web portion of the substantially U-shaped member. On the other hand, the joists and beams can be joined by an extremely simple operation of driving this metal fitting against elastic resistance.

従って、多数個所での接合作業全体を、従来の場合に比
し、遥かに迅速・容易に行なえる。Therefore, the entire joining operation at multiple locations can be performed much more quickly and easily than in the conventional case.

又この接合状態において、両フランジ部を弾性挾持して
いるので、振動を受けても、根太と梁との接合強度を保
持させることができ、従って床鳴りの発生を確実に防止
できる。In addition, in this joined state, since both flanges are elastically clamped, the joint strength between the joist and the beam can be maintained even when subjected to vibrations, and therefore the occurrence of floor noise can be reliably prevented.

もって接合作業の施工能率を極めて向上させることがで
きる。As a result, the efficiency of the joining work can be greatly improved.

その他、この金具は全体が一体物であるため、互いに別
体のボルト・ナツトに比し、取扱いおよび管理が楽であ
るといった利点もある。In addition, since this metal fitting is a single piece, it has the advantage that it is easier to handle and manage than separate bolts and nuts.

以下、本考案の実施例を図面に基づいて説明する。Hereinafter, embodiments of the present invention will be described based on the drawings.

る。First, both upper clamping pieces IB and IB are inserted into the opening 5B from below, and then the posture of the whole is changed by 90 degrees in each of the two dimensional directions, so that the posture of the metal fitting A is changed to the upper clamping piece 1B. be in a horizontal position along the longitudinal direction of the joist 5.

このとき、下方挾持片１Ａは開口部５Ｂよりも下方に位
置する。At this time, the lower holding piece 1A is located below the opening 5B.

この状態で、金具Ａを梁フランジ部４Ａ側に打込み移動

ランジ部４Ａ、５Ａ、５Ａは挾持固定される。That is, during driving, the lower clamping piece 1A and the upper clamping piece I
B and IB are forcibly expanded in a state that resists elasticity,
Due to the elastic restoring force exerted based on this, both the upper and lower flange portions 4A, 5A, 5A are clamped and fixed.

金具Ａは、パツキン材２を介して根太５に接合されるた
め振動が作用しても不測に脱落するおそれはない。Since the metal fitting A is joined to the joist 5 through the packing material 2, there is no risk of it falling off unexpectedly even if vibrations are applied.
