Description

この発明は、直交する向きにある構造材相互を引き寄せ状態に組み付ける連結金物におけるボルト受け金物の改良に関し、当該構造材相互を一方の施工側のみで、容易かつ確実に行うことのできるボルト受け金物、及び、当該ボルト受け金物の取付方法の提供に関する。   TECHNICAL FIELD The present invention relates to an improvement of a bolt receiving metal in a connecting metal that assembles structural members that are orthogonal to each other in a drawn state, and the bolt receiving metal that can be easily and surely performed only on one construction side. , And the provision of a method for attaching the bolt receiving hardware.

近時、建築物における構造材相互を引き寄せ状態に接合する手段として各種の建築金物が用いられている。
かかる構造材の接合に用いられる建築金物は、典型的に、一方構造材を貫通するボルトを他方構造材に備えられる羽子板金物やホールダウン金物で受け、このボルトに螺合されるナットを締め付けて、当該羽子板金物やホールダウン金物の備えられている構造材を他方の構造材に引き寄せ、当該引き寄せ状態で接合をするようにしている。 Recently, various construction hardware has been used as means for joining structural materials in a building together.
Building hardware used for joining such structural materials typically receives a bolt that penetrates one structural material with a wing metal plate or hole-down hardware provided in the other structural material, and tightens a nut that is screwed into the bolt. The structural material provided with the metal sheet metal or the hole-down metal is drawn to the other structural material and joined in the drawn state.

しかしながら、かかる構造材の接合方法では、接合される構造材に前もってボルトを挿通用意し、あるいは、ボルトの挿通孔を穿設用意する必要があり、また、当該構造材の引き寄せ状態での接合処理を、構造材の接合側と、当該接合側と反対の側とから処理する必要があり、構造材の接合処理に各種の制約があった。   However, in such a method for joining structural materials, it is necessary to prepare for insertion of bolts in advance to the structural materials to be joined, or to prepare for drilling holes for bolts. Need to be processed from the bonding side of the structural material and the side opposite to the bonding side, and there are various restrictions on the bonding processing of the structural material.

かかる点から、接合される構造材の接合側における処理で、当該構造材相互を接合するボルト受け金物が提案されている（例えば、特開２００７−２０５０６４）。
特開２００７−２０５０６４ From such a point, a bolt receiving metal for joining the structural materials by a process on the joining side of the structural materials to be joined has been proposed (for example, Japanese Patent Application Laid-Open No. 2007-205064).
JP2007-205064

しかしながら、接合される接合材における接合処理側において構造材に装着されるボルト受け金物であって、外周面に当該ボルト受け金物を構造材にねじ入れる雄ねじを備えた円筒状軸部を備えるボルト受け金物は見受けられなかった。   However, a bolt receiver that is attached to the structural material on the bonding processing side of the bonding material to be bonded, and that has a cylindrical shaft portion with a male screw that screws the bolt receiver into the structural material on the outer peripheral surface. No hardware was found.

この特許文献１に示されるボルト受け金物は、コーチねじ状のボルト受け金物としてあって、頭部に備えられている角形断面をなす凹部の底面から軸部の先端側に向けて雌ねじ孔を備える構成としており、当該雌ねじ孔を備えるコーチねじ状のボルト受け金物としてある。   The bolt receiver shown in Patent Document 1 is a coach screw-like bolt receiver, and has a female screw hole from the bottom surface of a concave portion having a square cross section provided in the head portion toward the distal end side of the shaft portion. It is configured as a coach screw-shaped bolt receiver provided with the female screw hole.

すなわち、この特許文献１に示されるボルト受け金物は、軸部が、その先端側から頭部の側に向けて外周に雄ねじを設けたコーチねじ状をなし、かつ、頭部に備えられている角形断面をなす凹部の底面から軸部の先端側に向けて雌ねじ孔を備えた構成としてある。   That is, in the bolt receiving metal object shown in Patent Document 1, the shaft portion has a coach screw shape in which a male screw is provided on the outer periphery from the tip side toward the head side, and is provided on the head. A female screw hole is provided from the bottom surface of the concave portion having a square cross section toward the distal end side of the shaft portion.

かかる点から、備えられる雌ねじ孔は、これを設けるために工夫が必要であり、しかも、軸部の一定範囲に限定されることとなり、軸部の全幅にわたって雌ねじを設け得ないことから、素材コストが割高となり、要請される引っ張り耐力に対応するボルト受け金物として比較的重量がかさむ傾向にあった。   From this point, the provided female screw hole needs to be devised to provide this, and is limited to a certain range of the shaft portion, and since the female screw cannot be provided over the entire width of the shaft portion, the material cost is reduced. However, there was a tendency that the bolt receiving metal corresponding to the required tensile strength was relatively heavy.

かかる点から、構造材相互の引き寄せ接合に際して、引き寄せ接合される当該構造材における接合側のみで当該引き寄せ接合ができると共に、より軽量で取り扱い易く、割安で、しかも、構造材の接合に要請される引っ張り耐力を備えるボルト受け金物が求められていた。   From this point, when pulling and joining the structural materials, the pulling and joining can be performed only on the joining side of the structural materials to be attracted and joined, and it is required to be lighter, easier to handle, cheaper, and to join the structural materials. There has been a demand for a bolt receiving metal fitting having tensile strength.
