Description

本発明は、地震、台風等により木造建築物に強度の振動が付加されても崩壊しないように、交差して接続されている建築構造材の接合部に取り付けて補強する耐震補強金具及びその係止部材に関する。 The present invention relates to a seismic reinforcing metal fitting that is attached and reinforced to a joint portion of a building structure material that is connected in a crosswise manner so as not to collapse even if strong vibration is added to a wooden building due to an earthquake, a typhoon, or the like. It relates to a stop member.

従来、木造建築物の構造材の接合部を補強する方法としては、筋交いや火打梁を設けたり、鎹、Ｌ型金具を取り付ける等、種々の方法が採用されている。
しかし、このような方法では、地震、台風等により強度の振動が付加された場合の補強効果は十分ではなく、接合部で構造材が簡単に離反したり、破損したりして、木造建築物がその接合部において破損したり、酷い場合には倒壊してしまうこともあった。 Conventionally, as a method for reinforcing a joint portion of a structural member of a wooden building, various methods such as providing braces, a struck beam, or attaching a gutter or an L-shaped bracket have been adopted.
However, with such a method, the reinforcement effect when strong vibration is added due to earthquakes, typhoons, etc. is not sufficient, and structural materials can be easily separated or damaged at joints, resulting in wooden buildings However, it may be damaged at the joint, or in a severe case, it may collapse.

そこで、垂直方向及び水平方向の振動等を吸収し、地震、台風等により木造建築物に強度の振動が付加されても崩壊しないように、鋼板材をＬ字状に折曲してなる第一部材と、この第一部材の折曲基底部に固定される補強部材と、第一部材の両端部に固定される第二部材とから構成され、交差する建築構造材の相互間に跨って取り付けられる耐震補強金具が提案されている（特許文献１参照。）。 Therefore, the first steel plate is bent in an L shape so that it absorbs vertical and horizontal vibrations and does not collapse even if strong vibrations are applied to the wooden building due to earthquakes, typhoons, etc. It consists of a member, a reinforcing member that is fixed to the bent base of the first member, and a second member that is fixed to both ends of the first member. A seismic reinforcing bracket is proposed (see Patent Document 1).

しかし、前記耐震補強金具では、設定前にあっては、第一部材、第二部材及び補強部材は分離しているので、保管時又は運搬時に、各部材の取扱いが面倒であると共に、分離して紛失しかねない状況であった。 However, since the first member, the second member, and the reinforcing member are separated before setting, the handling of each member is troublesome during storage or transportation and is separated. It was a situation that could be lost.

又、前記耐震補強金具を取り付けるには、各部材を互いに当接させ、互いの挿通孔を合わせてボルト等を挿通し、各部材が分離しないよう押さえながら取り付けていたので、設置作業も面倒であった。 Also, in order to attach the seismic reinforcement metal fittings, the members are brought into contact with each other, the bolts are inserted through the respective insertion holes, and the members are attached so as not to separate, so installation work is troublesome. there were.

本発明は、かかる問題点に鑑みて為されたものであり、複数の部材からなる耐震補強金具において、保管時又は運搬時に、各部材の取扱いを容易とし、分離して紛失しないようにすると共に、耐震補強金具の設置作業をも容易にする耐震補強金具を提供することを目的とする。 The present invention has been made in view of such problems, and in a seismic reinforcing metal fitting made of a plurality of members, it is easy to handle each member at the time of storage or transportation, so as not to be separated and lost. An object of the present invention is to provide a seismic reinforcement bracket that facilitates the installation work of the seismic reinforcement bracket.

上記目的を達成するために、本発明の耐震補強金具は、各部材の当接部分の挿通孔に、合成樹脂製であって、鍔状部、ニ本の脚状部、嵌合部から構成され、前記脚状部の先端部には爪状部を形成した係止部材を嵌着させたことを特徴とする。 In order to achieve the above object, the seismic reinforcing metal fitting of the present invention is made of synthetic resin in the insertion hole of the contact portion of each member, and is composed of a bowl-shaped portion, two leg-shaped portions, and a fitting portion. In addition, a locking member having a claw-shaped portion is fitted to the distal end portion of the leg-shaped portion.

BEST MODE FOR CARRYING OUT THE INVENTION

以下、本発明の耐震補強金具の好適な実施形態について、図面を参照しつつ具体的に説明する。
図１は、本発明の耐震補強金具の一実施例を示す斜視図であり、図２は、係止部材の（Ａ）は左側面図、（Ｂ）は正面図、（Ｃ）は右側面図、（Ｄ）は縦断面図である。 Hereinafter, preferred embodiments of the seismic reinforcing metal fitting of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of the seismic reinforcing metal fitting according to the present invention. FIG. 2 is a left side view, (B) is a front view, and (C) is a right side view of a locking member. FIG. 4D is a longitudinal sectional view.

本発明の耐震補強金具１は、図１に示すように、鋼板材をＬ字状に折曲してなる第一部材２と、この第一部材の折曲基底部に固定される補強部材４と、第一部材の両端部に固定される第二部材３とから構成され、各部材の当接部分の挿通孔２ａ，３ａ，４ａに、図２に示すような係止部材１１を嵌着させて成るものである。 As shown in FIG. 1, a seismic reinforcing metal fitting 1 of the present invention includes a first member 2 formed by bending a steel plate material into an L shape, and a reinforcing member 4 fixed to a bent base portion of the first member. And a second member 3 fixed to both ends of the first member, and a locking member 11 as shown in FIG. 2 is fitted into the insertion holes 2a, 3a, 4a of the contact portions of the members. It is made up of.

係止部材１１は、合成樹脂製であって、鍔状部１２、ニ本の脚状部１３，１３、嵌合部１４，１４から構成され、脚状部１３の先端部には爪状部１３ａを形成してある。 The locking member 11 is made of a synthetic resin, and includes a hook-shaped portion 12, two leg-shaped portions 13 and 13, and fitting portions 14 and 14. A claw-shaped portion is formed at the tip of the leg-shaped portion 13. 13a is formed.

鍔状部１２の外径は、耐震補強金具１の挿通孔２ａ，３ａ，４ａより若干大とし、脚状部１３の長さは、各部材の当接部分において、挿通孔２ａ，３ａ，４ａより爪状部１３ａが若干突出する長さとする。 The outer diameter of the bowl-shaped portion 12 is slightly larger than the insertion holes 2a, 3a, 4a of the seismic reinforcement bracket 1, and the length of the leg-shaped portion 13 is the insertion holes 2a, 3a, 4a at the contact portions of the respective members. The length is such that the claw-like portion 13a protrudes slightly.

各部材の当接部分の挿通孔２ａ，３ａ，４ａに係止部材１１を嵌着させた時、嵌合部１４，１４は挿通孔２ａ，３ａ，４ａに嵌合し、鍔状部１２は各部材の上面に位置し、脚状部１３，１３は挿通孔２ａ，３ａ，４ａを貫通して、爪状部１３ａ，１３ａが各部材の下面から若干突出する。 When the locking member 11 is fitted in the insertion holes 2a, 3a, 4a of the contact portions of the respective members, the fitting portions 14, 14 are fitted into the insertion holes 2a, 3a, 4a, and the hook-shaped portion 12 is Located on the upper surface of each member, the leg portions 13 and 13 pass through the insertion holes 2a, 3a and 4a, and the claw portions 13a and 13a slightly protrude from the lower surface of each member.

本発明の耐震補強金具１によれば、設定前にあっても、第一部材２、第二部材３及び補強部材４は係止部材１１によって接合されているので、保管時又は運搬時に、各部材の取扱いは容易であり、分離して紛失することはない。 According to the seismic reinforcing metal fitting 1 of the present invention, the first member 2, the second member 3, and the reinforcing member 4 are joined by the locking member 11 even before setting. The members are easy to handle and will not be separated and lost.

又、前記耐震補強金具１を設置する時、第一部材２、第二部材３及び補強部材４は係止部材１１によって接合されているので、ボルト等を挿通する際に各部材が分離しないよう押さえる必要はないから、設置作業も極めて容易となる。 Further, when the seismic reinforcement metal fitting 1 is installed, the first member 2, the second member 3 and the reinforcing member 4 are joined by the locking member 11, so that each member is not separated when a bolt or the like is inserted. Since it is not necessary to hold down, installation work is extremely easy.

さらに、係止部材１１は合成樹脂製であるから、係止部材１１を嵌着させたまま、ボルト等を挿通することができ、この点でも設置作業は容易となる。 Furthermore, since the locking member 11 is made of a synthetic resin, a bolt or the like can be inserted while the locking member 11 is fitted, and installation work is also facilitated in this respect.
