Abstract

PROBLEM TO BE SOLVED: To provide a joint bolt capable of providing expansion and a strong fastened state necessary when it is screwed on an old decayed bolt by inserting a component replacing a nut in a joint bolt body, and capable of adjusting the expansion and a fastening degree. SOLUTION: The joint bolt comprises a cylindrical joint bolt body with a male screw formed in an outer circumferential face, a female screw screwed onto an attachment object bolt such as the decayed bolt formed in an inner circumferential face, and a slit groove provided in one end part so the an inner diameter can be expanded, and a fastening band fit on the joint bolt body for maintaining an expansion limit of the inner diameter. The fastening band is a ring shape with one end opened as a fastening opening, protruding pieces are extended outward on both sides of the opening, through holes for a screw bolt are provided on both protruding pieces, and a fulcrum piece butting against one of the protruding pieces is formed in the other protruding piece so that a ring inner diameter can be reduced by fastening a nut and bringing both protruding pieces close.

2. Description of the Related Art For example, when renovating an old folded plate roof, this type of joint bolt leaves the existing rotten top bolts that stop the folded plate as it is, and adds a new joint bolt to it. By installing and using the connecting bolts, the new folding board roof is laid on the old folding board roof. The present applicant has already proposed a joint bolt used in this case (Japanese Patent Laid-Open No. 2000-2135).

The joint bolt described in the above publication is composed of a joint bolt main body and a nut. The joint bolt has a cylindrical shape, and a male screw is formed on the outer peripheral surface and a female screw is formed on the inner peripheral surface. One end of the joint bolt is formed. A pair of split grooves are formed diametrically so that they can be opened and expanded. For use, loosen the nut and screw it into the decay bolt from one end with the split groove.

In this case, since the joint bolt is allowed to open and expand in the gap between the screws due to the looseness of the nut, it is possible to screw it into the rotten bolt which is enormous due to rust, and the nut is fixed at the position of the split groove. Since expansion is blocked at the limit,
Stability is obtained by tightening the screws. Further, since the rusting is scraped off by the split groove, the resistance to screwing is reduced also in this respect.

However, since the split groove is formed by cutting and the edge of the screw thread is a sharp shape that is easily caught, when the nut is screwed into the joint bolt main body, it is apt to be caught, so that it cannot be manually turned. However, since the wrench is sometimes used because it cannot be screwed in, it is inconvenient for the mounting work for setting in advance.
In addition, the enormous state due to rust is divided by decay bolts, but the looseness of the nut is not dimensionally flexible, so
There was a problem that we could not deal with each situation.

The present invention has been made in view of the above circumstances.
By inserting a part that replaces the nut into the main body of the joint bolt, not only will the required expansion and firm tightening be obtained when it is screwed into an old decaying bolt, but also the degree of expansion and tightening. The purpose is to provide a joint bolt whose degree can be adjusted.

In view of the above situation, the present invention forms a male screw on the outer peripheral surface and a female screw on the inner peripheral surface to be screwed into a bolt to be attached such as a decaying bolt. In addition, it consists of a tubular joint bolt main body with a split groove at one end so that the inner diameter expands, and a tightening band inserted into the joint bolt main body to hold the expansion limit of the inner diameter. The band has a ring shape with one end open as a tightening hole, and outwardly extending protrusions are provided on both sides of the opening. The joint bolt is characterized in that a fulcrum piece that abuts the other projecting piece is formed at the tip of one projecting piece so that the inner diameter of the ring can be reduced by bringing the projecting pieces closer to each other.

Since the joint bolt is constructed as described above,
When screwing into the bolt to be attached, the tightening band is inserted into the position of the split groove in advance and assembled and set, but the screw bolt is loosely tightened so that it will not come off at that time. With this, the split groove of the joint bolt main body can be opened and expanded to a certain limit, but it is possible to cope with the rot and enormous amount of the bolt to be attached depending on the tightening condition of the screw bolt.

By this adjustment, not only can it be attached to any bolt to be attached which is in a rusty state in accordance with the situation at the site, but if necessary after the screwing operation, the screw bolt is operated again and the last screw is operated. Since tightening can be done depending on the rusting condition, a strong and stable installation is always possible. Further, when tightening the screw bolt, a fulcrum is set at a position where the fulcrum part piece abuts on the other projecting piece, and the tightening band is uniformly reduced.
