本発明はガス圧接により棒鋼材を接続する際に使用する
接続器具に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device used for connecting steel bars by gas pressure welding.
従来、建築物等の構築に使用する棒鋼材の接続はガス圧
接法によりなされている。Conventionally, the connection of steel bars used in the construction of buildings, etc. has been made by gas pressure welding.
しかしながら、近来、橋梁や建築物が大型化するに従い
大径の棒鋼材が使用されるに至り、接続面が大きくなつ
た結果、小口径の棒鋼材とは異リ接続面間の隙間が増え
たり、加熱溶接時の時間が、増えたりするため当接面に
おいて酸化物が生成する等の支障が生じ、特に大径の棒
鋼材は大過重がかかるため災害防止重要な問題を生じ、
これに対処するため棒鋼材の接続の際に接続面にフラッ
クスを塗布することが行われている。However, in recent years, as bridges and buildings have become larger, large-diameter steel bars have been used, and as a result, the connection surfaces have become larger, which is different from small-diameter steel bars, and the gap between the connection surfaces has increased. , as the time during hot welding increases, problems such as the formation of oxides on the contact surfaces occur, and especially large diameter steel bars are subject to heavy overload, which causes important problems in preventing disasters.
To deal with this problem, flux is applied to the connection surfaces when connecting steel bars.
しかしながら、ガス圧接による棒鋼材の接続時・ にお

棒鋼材の接続は一ク部の有能な作業者が行え得るのみで
あり、この場合も接続強度を増すため接続部が膨出し、
あるいは多くの作業時間を費すこととなる。However, when connecting steel bars by gas pressure welding, the flux applied in advance is blown away by the high-pressure flame during heating because the joint surface of the steel bars is heated with a high-pressure burner, so the effect of flux is not sufficient. It is difficult to obtain a connection with high connection strength, and currently only a few competent workers can connect large diameter steel bars, and in this case too, it is necessary to increase the connection strength. Therefore, the connection part bulges,
Otherwise, it will take a lot of work time.
したがつて大型の建築物や橋梁の工事が中断し、あるい

てなされたものであり、ガス圧接による棒鋼材の接続の
際にフラックスの〜効果が充分で接続面に酸化物が生じ

鋼材接続器具を提供するものである。As a result, construction of large buildings and bridges has been suspended or delayed. 7 The present invention has been made in view of the above points, and the effect of flux is sufficient when connecting steel bars by gas pressure welding, and oxides are not generated on the connecting surfaces, and ordinary workers can easily do so. The present invention provides a steel bar connecting device that can perform connection work.

る。FIGS. 1 and 2 show an embodiment of the steel bar connecting device according to the present invention, and the connecting device 1 is made of the same material as the steel bar to be connected or a material with a low carbon content (for example, three-nine steel). ) is used to close one side of a cylinder with a diameter slightly larger than the diameter of the steel bar to be connected to form the cap 2, and at the same time, the open end is expanded and bent to form the stepped portion 3. , and a paste-like flux 4 is housed inside, and a cover 5 made of the same material as the cap 2, synthetic resin, paper, etc. is fitted and tightly attached to the stepped portion 3.

Next, the cover 5 of the connecting device 1 is removed, and the connecting ends of both steel bars 6 of the cap 2 are covered with the cap 2, as shown in FIG.

度を有する圧接を容易にすることができるものである。Then, the paste-like flux of this cap 2 closes the gap between this cap 2 and the steel bar 6. Then, as shown in FIG. 4, both steel bars 6 are brought into contact with each other via the cap 2 and are welded together by gas pressure. Unlike the conventional case, during gas pressure welding, the flux 4 is covered by the cap 2, so the flux will not be blown away by the force of the burner before the connection end of the steel stock 6 is heated. In addition, the cap 2 interposed between the two steel bars 6 melts and acts to connect the two steel bars 6, making it possible to easily connect the two. At this time, if the cap 2 is made of a high-purity steel material, oxidation during gas pressure welding can be further reduced and a stronger connection can be achieved. In addition, in this embodiment, the connecting device A is placed on both connecting ends of the steel bar 6, but it may be placed on only one side, or the two connecting devices are connected from the beginning as shown in Fig. 5. It is also possible to have such a configuration. Furthermore, when the cover 5 is made of paper, it is flammable and can be easily disposed of on site. Furthermore, when the flux 4 is in a dry state, it does not flow down when it is attached to the steel bar 6 and at the initial stage of pressure welding, and the work can be carried out more efficiently. In the above embodiment, the step 3 is formed in the cap 2, and the cover 5 is fitted into the step 3. However, the cover 5 is designed to prevent the flux 4 stored inside the cap 2 from flowing out. It may be configured to directly cover the open end of the cap 2, or may be omitted if a dry flux is used. Since the present invention has the above-mentioned configuration, the flux effect is sufficient, and the molten cap and the flux form a gap between the connecting surfaces of the steel bars that are pressed against each other, without producing a large amount of oxides on the connecting surfaces. Therefore, an ordinary worker can easily press-weld not only a steel bar of a normal diameter but also a steel bar of a large diameter with sufficient strength.
