The frame handrail 7 is formed to be foldable with respect to the main body 5, and the support column 8 is also formed to be foldable or detachable with respect to the extendable body 6. This is intended to improve the workability when relocating the walkway 2 and transporting it.

The walkway connector 1 according to the present invention, which connects the side part of one walkway 2 configured as described above to the end of the other walkway 2, is as shown in FIGS. 2 to 4. , has a pressing member 11 that comes into contact with the upper surface of the side of one of the hallways, and a hook member 12 that is swingably disposed on the pressing member 11, and is adjacent to the side of one of the hallways 2. In order to effectively prevent the end of the other walkway 2 from swinging vertically with the side of one walkway 2 or separating from the side of one walkway 2. It is being formed.

The pressing member 11 has a fixing portion 13 that connects the pressing member 11 to the end bracket 2a of the walkway 2. This fixed part 13 has a bolt hole 13'.
is bored (see Fig. 3), and the bracket 2a is inserted into the bolt 14 inserted into the bolt hole 13' and tightened with a nut 15 to fix the pressing member 11 to the end of the walkway 2. It is something.

The body part 16 of the pressing member 11, which is connected to the fixed part 13 in the form of an arm, has a horizontally long hole 16' bored through its wall thickness. A bolt 17 with the hook member 12 interposed therebetween is inserted into the bolt 16', and
A fastening nut 18 is screwed onto the bolt 17 (see FIG. 3).

Since the lower surface of the main body 16 of the arm-shaped pressing member 11 is brought into contact with the upper surface of the side part of the walkway 2, in this embodiment, the pressing member 11 has an appropriate medium contact surface. The abutting portion 16a is formed as shown in FIG. Of course, may be omitted.

Further, in this embodiment, the tip of the main body portion 16 formed in an arm shape has a hook portion 19 hanging downwardly.
By bringing the inner surface into contact with the side rear surface of the connector, it functions to prevent separation of one of the aisles 2 to which the connector 1 is attached and the other aisle 2. , hook member 1 to be described later.
2, it goes without saying that the formation of the hook portion 19 may be omitted.

The hook member 12 has a horizontally elongated hole 16' formed in the main body 16 constituting the pressing member 11.
It is rotatably held by a bolt 17 inserted therein, and has a hook portion 20 at its lower end and a tension portion 21 at its upper end.

The hook portion 20 is adapted to be locked to the edge of the shaped steel constituting the walkway 2, and in this embodiment, an upwardly directed claw portion 20 is attached to the tip of the hook portion 20.
a is formed, but depending on the shape of the edge of the shaped steel constituting the walkway 2, the formation of the claw piece portion 20a may be omitted.
