Description

本考案は、ねじ込み式バックボルトに関し、更に詳しくは、石材や複合板等の対象物に固装されて使用されるねじ込み式バックボルトに関する。   The present invention relates to a screw-type back bolt, and more particularly, to a screw-type back bolt used by being fixedly mounted on an object such as a stone or a composite board.

従来の石材等の対象物の固定に用いられる固定装置は、ねじ棒８０及びスリーブ９０を備える。ねじ棒８０はスリーブ９０中に貫設され、前記スリーブ９０は形状が同じであると共に対応しあう２つの治具ブロック９１で構成される。これら前記治具ブロック９１には外に向けて延伸されるストッパー９２が設けられ、且つ２つの治具ブロック９１には対応しあう表面にスレッド９１１が設けられ、前記スレッド９１１はねじ棒８０上のスレッドに相互に螺合される（図１参照）。   A conventional fixing device used for fixing an object such as a stone material includes a screw rod 80 and a sleeve 90. The threaded rod 80 is passed through a sleeve 90, and the sleeve 90 is constituted by two jig blocks 91 having the same shape and corresponding to each other. The jig blocks 91 are provided with stoppers 92 extending outward, and the two jig blocks 91 are provided with threads 911 on corresponding surfaces. The threads are screwed together (see FIG. 1).

図２に示されるように、使用に際しては、まず治具ブロック９１が対象物６０に予め設けられる穴７０中にそれぞれ装設され、ねじ棒８０が治具ブロック９１中に貫設され、治具ブロック９１のスレッド９１１がねじ棒８０上のスレッドに相互に螺合される。ねじ棒３０により治具ブロック９１が押されると外に向けて徐々に拡張され、ストッパー９２が穴７０の壁面に係合され、治具ブロック９１が穴７０中に固定される。   As shown in FIG. 2, in use, first, a jig block 91 is provided in each of holes 70 provided in advance in the object 60, and a screw rod 80 is provided through the jig block 91. The thread 911 of the block 91 is mutually screwed with the thread on the threaded rod 80. When the jig block 91 is pushed by the screw rod 30, the jig block 91 is gradually expanded outward, the stopper 92 is engaged with the wall surface of the hole 70, and the jig block 91 is fixed in the hole 70.

しかしながら、前述した従来の技術では、スリーブ９０が別々に分解される２つの板片体で構成されるため、対象物６０の体積が過大である場合、発生スリーブ９０が外に向けて拡張されるが末端が前記対象物６０の重量を支えきれず前記対象物が脱離しやすくなり、対象物６０が固定箇所から脱落してしまい、理想的とは言えなかった。   However, in the above-described conventional technique, since the sleeve 90 is composed of two plate pieces that are separately disassembled, when the volume of the object 60 is excessive, the generation sleeve 90 is expanded outward. However, the end cannot support the weight of the target object 60, and the target object is easily detached, and the target object 60 falls off from the fixed portion, which is not ideal.

そこで、本考案者は上記の欠点が改善可能と考え、鋭意検討を重ねた結果、合理的設計で上記の課題を効果的に改善する本考案の提案に至った。   Therefore, the present inventor considered that the above-mentioned drawbacks could be improved, and as a result of diligent studies, came to a proposal of the present invention that effectively improved the above-mentioned problems with a rational design.
