Conventionally, the length of the thick timber used in concrete formwork has been determined, and it has been impossible to change the length to suit the conditions of use. For this reason, it was necessary to prepare end pieces of various sizes depending on the usage conditions, which was uneconomical. In view of these circumstances, 2
Various types of connectors have been implemented in which a length-adjustable connecting portion is provided using book ends, but all of them have had problems in terms of workability and reliability of connection.

The connecting part of this invention is to wrap and connect two groove-shaped end members whose web surfaces are in contact with each other, and includes a rectangular cylindrical band-shaped metal fitting, and the band-like metal fitting and the end member. and a wedge installed between.
以下、この考案を図面に示す実施例に基づいて
説明する。図において符号１は端太材、２帯状金

This invention will be explained below based on embodiments shown in the drawings. In the figure, numeral 1 is a thick piece of material, 2 is a band-shaped metal fitting, and 3 is a wedge.

るものである。 The connecting part of this invention is made by standing up two thick end pieces made of groove-shaped steel, abutting each other's web surfaces, and then enclosing both thick end pieces with rectangular cylindrical band-shaped metal fittings 2. A wedge 3 is driven between the ends and the web surface of the thick end material is pressed against the inner surface of the band-shaped metal fitting, thereby fixing it.

る。 The band-shaped metal fitting 2 is formed from hollow steel having a square cross section or by processing a band-shaped steel plate into a square tube shape. That is, the metal band has a closed cross-sectional structure, has high rigidity, and has high resistance to external forces such as bending, compression, and tension, so that the plate thickness can be reduced. Therefore, it is possible to reduce the weight of the members and save on materials.

角形とした。 After wrapping the end pieces 1 and 1 with the band-shaped metal fitting 2 and adjusting the length of both end pieces to the required length, a wedge is installed between the band-like metal fitting 2 and the end piece 1, and the joint device is assembled. The installation work has been completed. The wedge is made of wood or hard resin to improve safety during work. In addition, the shape is rectangular on the plane and the bottom, and only the sides are triangular.

うな手順で取付ければ、作業を容易かつ確実に行
うことができる。 In the embodiment, the side surface is a scalene right triangle, but there is no need to be limited to this. However, the contact area can be increased by making the portion that contacts the end piece and the band-shaped metal fitting rectangular as in the embodiment. Also, the maximum thickness of the wedge must be slightly larger than the flange width of the end pieces to be joined. It will be easier to work if the length is about twice the length of the metal band. When installing the joint, lay the end piece down, insert it into the band-shaped metal fitting, drive a wedge, stand it upright, and tap the end of the wedge again. By following these steps, the work can be done easily and reliably.
第２図にこの考案の帯状金具を用いて施工した

きる。 Figure 2 shows a net formwork constructed using the band-shaped metal fittings of this invention. In this embodiment, the band-shaped metal fittings were used only for the pillars, but they can also be used for the horizontal ends.

The configuration of this invention is as described above, and according to this invention, two end pieces can be joined reliably and easily, and the length can be easily adjusted. Furthermore, if the band-shaped metal fittings of this invention are provided at the ends of the two groove-shaped end pieces, they can also be used as H-shaped end pieces.
