PURPOSE:To easily transport a microwave repeater station shed and to change the internal volume of the shed so as to make construction works of a microwave repeater circuit easier, by using a freely expandable accordion system member and fitting the front wall equipped with a door to the main body of the shed by means of the member. CONSTITUTION:A front wall 2 equipped with a door 3 is fitted to the main body of a microwave repeater station shed, to the back wall of which communication appartuses are arranged, by means of an accordion system member 4 under an expansion-free condition. When the shed is transported, the member 4 and front door 2 are fixed by means of fittings 5 and, when the shed is brought to a construction site, the fixation between the front wall 2 and fittings 5 is released and the fittings 5 are turned around shafts 6. Then the member 4 is expanded and a working space is prepared. By changing the internal volume of the shed by expanding and contracting the member 4, transportation of the shed is made easier and, as a result, construction works of a repeater circuit including a microwave repeater station shed are made easier. |
