That is why an important process, transport of unit module, is added in this technique. However, it is not easy to transport a unit module that is high prefabrication ratio （prefab. ratio） （70-90%）, since the walls and interior and exterior materials installed in it can become broken when the unit module is fixed using general fixation tools, including ropes and fixing belts. When the external wall, windows, etc. are damaged during the transportation, the efficiency of unit modular method is deteriorated. Taking this into account, the purpose of this study is to develop an improved fixation device that is convenient for fixing a unit module with a high prefab, ratio to a vehicle and securing the safety while running. The L-type adapter block proposed in this study was evaluated the structural safety through simulation method. The result of the simulation is that it seems desirable to set the working load of the L-type adapter block as 15 kN for Case 1 and 30 kN for Case 2. Therefore, when the L-type adapter block is utilized under the conditions in which the same load is applied as in Case 2, it is expected that safety will be improved.展开更多
