Construction method of tire type gantry crane frame beam
The invention discloses a construction method of a tire type gantry crane frame beam. The method comprises the steps that firstly, pier top padstone is cast, and support bolt holes are reserved; before erecting is carried out, temporary supporting jacking blocks are placed on the two sides of the pier top padstone, and the top face elevation of the jacking blocks is adjusted to meet the design position of supports; after the supports are mounted on a girder field in advance, box girders are discharged out of the girder field, and when the box girders are transported to the site, gantry cranes are in place in advance; the box girders are transported to the site by a girder transporting vehicle, the box girders are lifted to the corresponding positions by two tire type gantry cranes to be in place, after the two box girders of a hole are erected, reserved reinforcing steel bars of the two box girders are temporarily connected, and stability and safety of the box girders are ensured; then, the gravity type grouting manner is adopted, gaps between the lower portions of the supports and bolts are grouted, after mortar reaches the strength, accessory components like support connecting plate are dismounted, support surrounding plates are mounted, the temporary supporting jacking blocks are dismounted, and the box girders of the hole are erected. The method can meet erection of the box girders of any span, and skip erection can be achieved according to the construction progress; and the method is high in construction speed, high in safety, high in efficiency, low in cost and good in economical performance.
