withstanding uplift loads a very important factor in resisting hurricane force winds with the present invention no individual clip is left only to its own mounting screws to survive the entire u201c l u201d bracket is held down to the roof by a series of screws along the u201c l u201d bracket no one clip can be pulled up the entire u201c l u201d bracket with all its mounting screws would have to be moved at once in an upward direction against the holding force of all the screws the result is a substantially greater resistance to up lift forces is provided by the present invention the clips are held securely by the continuous clip of the present and its many mounting screws where the continuous clip is used with purlins and the mounting screws or other mounting attachment means make a rigid connection between the bracket and the purlins the bracket of the continuous clip prevents racking of the purlins because it forms a rigid box structure this feature strengthens the roof and the building against uplift and other loads the bracket may be rigidly attached to the purlins by using two or more screws welding riveting square pins or other rigid attachment means at each junction of the bracket and the purlins this rigid attachment prevents rotation of the brackets with respect to the purlins and this prevents purlin roll when the purlins roll they can be turned sideways where they may have no strength allowing them to be bent up due to uplift wind loads when this occurs the roof may be blown.
