Abstract

PROBLEM TO BE SOLVED: To easily attach an additional bolt and nut to an intermediate portion of members after fastening the members by means of the bolt and nut, without detaching the fastened bolt and nut even when requirement of the fastening additionally occurs. SOLUTION: This device performs connection of members A and B such as extrusion mold by the use of a specific bolt 1 having a longitudinally long head 1a and an usual nut 2, or a usual bolt and a longitudinally long specific nut, and a rotation preventive means 3 which is U-shaped from side view. The first member A has an inner portion widening groove 4 in its longitudinal direction, while the second member B has a bolt shaft through-hole 8. After a head 1a of the specific bolt 1 or nut 2 is turned by a specified angle in the inner portion widening groove 4 of the first member A, the rotation preventive means 3 is fitted into the inner portion widening groove 4, for preventing counterrotation of the specific bolt head 1a or the nut 2.

題があった。However, in the conventional device for joining members using bolts and nuts, it is necessary to fit the hexagonal head of the bolt into the internal enlarged groove of each member from the end of each member. Therefore, for example, after two members are connected by a plurality of sets of bolts and nuts, when a new portion requiring fastening is generated in the middle of the members, the head of the additional bolt is no longer required inside the member intermediate portion. It is not possible to fit into the enlarged groove, and if it is absolutely necessary to add bolts and nuts, it is necessary to remove the bolts and nuts already fastened from the end of the member to the new required location and add bolts However, there is a problem that the connecting work of the members is troublesome and very troublesome.

置を提供しようとするにある。SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, since a fastening bolt / nut can be freely mounted at any position in the longitudinal direction of a member and has a function of stopping rotation. Therefore, even if the bolts and nuts are not disengaged, and therefore, for example, when a new part requiring fastening is formed after the fastening of two or three members by a plurality of sets of bolts and nuts, additional bolts and nuts can be used. The nut can be easily installed in the middle of the member,
Accordingly, it is an object of the present invention to provide a member connecting device using bolts and nuts, which does not require removing the bolts and nuts already fastened, and enables the members to be connected very easily and reliably.
