PURPOSE: To make the survey convenient and to reduce the manhours for a dangerous high place work by fixing a suspender bed for holding a plurality of suspenders, to a roof body.
CONSTITUTION: A suspender bed 10 is to be formed from a long plate member having a connecting piece 11a. Next, both sides of the plate member are bend. Further, the end parts of the folded sides are bent outward, leading a gap in which slide suspenders 15 slide, so as to define a resilient retainer part. Then, holes 14 for fixing the suspender bed 10 to a roof body are formed at suitable intervals. Meanwhile, the center of the lower end part of the plate member is cut, and then the plate member is bent in opposite directions, and further is bent upward and inward so as to form bent parts. Next, several slide suspensors 15 are inserted from one end part of the suspender bed 10. In this case, the frictional force of the resilient retaining part of the suspender bed 10 and the bent part of each of the slide suspenders 15 prevents the slider suspender 15 from being positionally shifted. Then, the suspender bed 10 holding several slide suspenders 15 is secured to the roof body.
