It contained danger. Furthermore, in the case where a pin is provided at the end of the scaffolding frame pipe, handling is inconvenient because it is necessary to twist the scaffolding frame pipe when inserting the pin. Since this structure is simply inserted, there is a possibility that the scaffolding frame pipe may come off.

らず、取扱に便利である。(Function) In the present invention, the bolts 8 and 9 screwed into the support ring 5 so as to be able to move forward and backward are inserted into the support members 3 and 4 inserted into the support ring 5.
When the bolts 8 and 9 are rotated to move the support members 3 and 4 closer together or apart, the outer surfaces of the support members 3 and 4 are connected to the scaffold frame pipes 1 and 2.
can be easily connected or separated by simply rotating the bolts 8 and 9.Furthermore, since the bolts 8 and 9 are provided on each of the supports 3 and 4, the supports 3 and 4 are pressed against the inner surfaces of the scaffolding frame pipes 1 and 2, respectively, to ensure a secure connection.
Since the locking protrusions 16, 17, 18, 19 are protrudingly provided at positions corresponding to the locking holes 12, 13, 14, 15 drilled in the locking holes 12, 13, 14, 15 and are removably provided, the locking protrusions 16,
17, 18, 19 are locking holes 12, 13, 14, 1
5, the supporting members 3, 4 and the scaffolding frame pipe 1,
2 can be reliably connected to the connecting pipes 1, 2, and the locking protrusions 16, 17, 18, 19 can be connected to the locking holes 12, 13, 1 with the support members 3, 4 joined to the connection pipes 1, 2.
4 and 15, it is securely engaged and does not come off inadvertently, making it possible to connect extremely reliably.
Moreover, since the end of one support member 4 is bent so that when the support members 3 and 4 are brought close to each other, it abuts on the inner surface of the other support member 3, so that the support members 3 and 4 are brought closer to each other. Since the supporting members 3 and 4 can be brought into contact and fixed so that they do not shift, the supporting members 3 and 4 do not come apart and are convenient to handle.

4 are screwed into the bolts 8, 9 and threaded parts 10, 11, so the supports 3, 4 are in contact with the inner surfaces of the scaffolding frame pipes 1, 2, and the engagement provided on the supports 3, 4 is The locking protrusions 16, 17, 18, 19 are provided in the locking holes 12, 13, 14, 15 of the scaffolding frame pipes 1, 2 (the locking holes 13, 15 are drilled at symmetrical positions with 12, 14 in FIG. 5). ) and a complete connection is made. At this time, since the supporting members 3 and 4 have a shape that contacts the inner peripheral surface, they reliably contact the scaffolding frame pipes 1 and 2, and the locking protrusions engage with the locking holes, and the scaffolding frame pipes 1 and 2 can be firmly connected.

近づくように構成されている。 The supporting members 3 and 4 are formed in a curved shape so as to have surfaces of the same shape as the inner circumferential surfaces of the scaffold frame pipes 1 and 2 to be connected, and the central axis of the curved shape side is formed near both ends of the supporting members 3 and 4. Locking protrusions 16, 17, 18, 1 on top
9 is fixed by welding or other methods and erected,
The screw portions 10, 11 are screwed into the middle points between the locking projections 16, 17, 18, 19 (a nut may be fixed). In addition, the outer surfaces of the arc-shaped plate-shaped supports 3 and 4 are formed in a shape that overlaps with the inner surfaces of the scaffold frame pipes 1 and 2, so that they are opposed to each other so as to match the shapes of the scaffold frame pipes 1 and 2. It is inserted into the support ring 5. The threaded portions 10 and 11 formed in the support members 3 and 4 have the tips of bolts 8 and 9 inserted into holes 6 and 7 bored at positions facing each other in the circumferential direction of the support ring 5. They are screwed together. When the bolts 8 and 9 are rotated, the threaded portions 10 and 11 of the supports 3 and 4 are engaged in different positions, so that the supports 3 and 4 approach the inner surface of the support ring 5.

邪魔に成らずに挿入出来る必要がある。 In the embodiment, one of the supporting members 3 and 4 is
As shown in FIG. 4, the bolt 8,
When the support member 4 is moved inward by rotating the support member 9, the end portion of one support member 4 brought close to the other support member 3 is prevented from coming into contact with the inner surface of the other support member 3 and falling apart. This prevents the other supporting members 3 and 4 from becoming a hindrance and making inward movement difficult. In addition, the sizes of the locking protrusions 16, 17, 18, 19 are the same as those of the locking holes 12, 1 of the scaffold frame pipes 1, 2.
3, 14, 15, and is of a size that can be locked to the scaffolding frame pipes 1, 2 and does not get in the way when the supporting members 3, 4 are moved inward when inserting the scaffolding frame pipes 1, 2 into the scaffolding frame pipe fitting. It must be possible to insert the
また、支持材3,4を湾曲状としたのは実施例

状にしたものを用いることはいうまでもない。 Moreover, the support members 3 and 4 are curved because the scaffold frame pipes 1 and 2 used in the example are circular pipes, and when square pipes are used, the support members 3 and 4 are curved. Needless to say, a material whose outer surface is shaped so that it can overlap with the inner surface of the square pipe is used.
次に足場枠用パイプ継ぎ金具と足場枠用パイプ
1,2の結合手順について述べる。 Next, the procedure for connecting the scaffolding frame pipe fittings and the scaffolding frame pipes 1 and 2 will be described.

す状態になる。 By rotating the bolts 8 and 9, the supports 3 and 4 are moved inward to the state shown in FIG. In this state, insert the supports 3 and 4 into the scaffolding frame pipes 1 and 2, tighten the bolts 8 and 9, and move the supports 3 and 4 as shown in Fig. 5. The locking projections 16, 17, 18, 19 are locked in the locking holes 12, 13, 14, 15 of the scaffold frame pipes 1, 2 (see FIG. 6). At this time, the supports 3 and 4 are fixed to the support ring 5 with bolts 8 and 9, so the supports 3 and 4 are fixed to the support ring 5 with bolts 8 and 9.
Both ends of the scaffolding frame pipes 1 and 2 come into contact with the inner surfaces of the scaffolding frame pipes 1 and 2, and the scaffolding frame pipe fittings and the scaffolding frame pipes 1 and 2 are completely joined. The scaffolding frame pipe fittings and the scaffolding frame pipes 1 and 2 can be separated by performing the joining operation in the reverse order, resulting in the state shown in FIG. 4.
