Roof lift anchor for accommodating all force-transmitting parts used during installation of roof truss of house

摘要

The roof truss (3) can be installed on the base plate of the housing, whereby the supports are so fixed to the roof lift anchor that on lifting the roof truss they fold outwards or can slide in guide tubes and form parts of the building skeleton. The device is provided with accommodations for several crane hooks or hydraulic lifting devices, with which the complete structure can be raised. The simple housing skeleton comprises the roof truss (3), ridge purlin (2), steel profile structures (4) screwed to the foot purlins (1), screwed-on steel bearers (5) and two supports screwed to the bearers by means of welded-on hole plates.
