Description of the Related Art For example, buildings such as buildings, factories, stores, and station yards have long lengths called raceways (dimensions smaller than a predetermined value) or ducts (dimensions larger than a predetermined value). A lip grooved steel (hereinafter collectively referred to as a duct) is provided. That is, as shown in FIG. 14, a duct 1 is disposed along a ceiling or a wall surface along a ceiling or a wall surface by a support member (for example, a hanging metal fitting 2). The cord is wired in the duct 1. (Note that in FIG. 14, 3 is the duct 1

ダクトに干渉しない。For this purpose, both ends of the fitting in the longitudinal direction are inserted into ducts each having a lip edge, and screws are attached to the screw holes from the inside of the bottom plate, and the bottom plate of the duct is pressed with the tips of the screws to join the duct. Fix the two ducts by contacting the upper ends of both side plates of the metal fitting to the inside of the lip edge of the duct,
By holding the two ducts thus fixed in hand and applying a force to bend the intermediate portion of the bottom plate of the duct fitting in the longitudinal direction to a desired angle, each bottom plate of the two ducts can have a desired angle. Thus, the two ducts can be connected to each other so that the two ducts can be easily connected at a desired angle without cutting or welding. Further, since the corner of one side plate is formed in an arc shape, the angle of the side plate does not protrude at the time of bending and does not interfere with the duct.

いる。According to a third aspect of the present invention, the longitudinal direction of the bottom plate, the side plates provided on both sides in the width direction of the bottom plate, and the longitudinal middle portion of the one side plate can be bent. A notch provided at a middle part in the longitudinal direction of the other side plate from a middle part of the other side plate, one duct is connected to each of both ends in the longitudinal direction, and a middle part in the longitudinal direction of the one side plate is provided. And a duct fitting for connecting the two ducts so that each side plate of the two ducts has an arbitrary angle by bending the duct, wherein an intermediate portion of the one side plate is separated by the notch. When the bottom plate and the other side plate are bent in a direction approaching each other,
In order to prevent the bottom plates from interfering with each other, a stepped plate is provided on one of the bottom plates separated by the notch, screw holes are provided on both ends in the longitudinal direction of the bottom plate, respectively, inside the duct made of lip channel steel. By inserting the end portions of the bottom plate and both side plates and pressing the bottom plate of the duct with the tip of a screw screwed into the screw hole, the both side plates are pressed inside the lip edge of the duct to form a duct. I am trying to fix it.
