<p><P>PROBLEM TO BE SOLVED: To provide a structure installation frame, having high strength against both load and wind pressure, and decreasing the number of parts to lower the cost. <P>SOLUTION: When the whole of the structure installation frame 1 is seen, a mounting crosspiece 4, a longitudinal support 5 and a tension bar 6 are combined like a right-angled triangle. In this type of frame 1 formed like a right-angled triangle, even when force is applied to the mounting crosspiece 4 from any direction, the force can be dispersed to the mounting crosspiece 4, the longitudinal support 5 and the tension bar 6 and received by the same, so that the strength of the frame 1 is heightened. Moreover, the doubled inclined end face part 12a and tip part 4a of the tip style part 12 of the mounting crosspiece 4 are increased in strength as compared with that of a single layer part, and reinforced by a reinforcing member 13. Thus, even when the force applied to the mounting crosspiece 4 is concentrated on the tip part 4a, the tip part 4a can withstand this force. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
