The utility model further improves and is that described girder comprises three H shaped steel that weld together side by side, and the model of described H shaped steel is H650*300*12*18.
The utility model further improves and is that described secondary beam adopts No. 22 channel-section steels.
The utility model further improves and is, the two ends of described secondary beam connect steel plate by one respectively and fixedly connected with described girder, one side and the described Main Girder Welding of described connection steel plate are fixed, the opposite side of described connection steel plate is corresponding with the two ends of described secondary beam to offer plural bolt hole, is connected and fixed by bolt.
The utility model further improves and is that the two ends, bottom of described girder are respectively equipped with a pressure-bearing steel plate.
The utility model is owing to adopted above technical scheme, make it have following beneficial effect to be: by between reinforced concrete floor and large-scale crawler crane, a subgrade case being set, deadweight and the maximum of large-scale crawler crane are lifted by crane load by being delivered to earlier on the subgrade case, be delivered on the floor frame beam by subgrade case again, slow down the load that floor bears, subgrade case adopts the connected mode of girder and secondary beam, the back-up coat working space is big, little to the construction activities influence, the flooring reinforcement cost is low, and have easy construction, safe.
