CONSTRUCTION METHOD OF ROOF STRUCTURAL BODY

摘要

PURPOSE:To shorten a construction period and remarkably reduce a construction cost by eliminating the need for a support or a jack or the like at the tip of this support and its preparation work as well and reducing the frequency of using a wrecker. CONSTITUTION:An outer roof structural body 6 is constructed in a skeleton 5 of an athletic field 1 in such a fashion that it may face the inside of the field 1. The outer end of an inner roof block 13 is pin-jointed with an inner peripheral part of this outer structural body 6. The inner roof block 13 is erected by an erection means and then adjacent inner roof blocks 43 are connected to each other with an inner truss member, thereby constructing an inner roof structural body 7. The whole inner roof structural body 7 is fastened (jacked down) with the erection means.
