Cross-under has connecting screw rod on a word pier of a described word pier side end member, in order to be fixedly connected with described L shaped baffle component.
Base top surface in the described word pier side end member is downward-sloping from inside to outside slope.
The antiskid that is provided with downward grafting usefulness at the base of a described word pier side end member moves the steel axle.
Lower edge at described L shaped baffle component is provided with connecting bolt.
Suppressed on the whole the ballast member at described cross column foot.
Be respectively arranged with to peg graft at described cross pier side end member and interface between the described word pier side end member and cooperate the shear key of usefulness.Shear key comprises convex shear key and matrix shear key.
The utility model is by two kinds of assembly groups with the pier member, under the cross-under and prestressed stretch-draw effect of prestressing force drawing steel stranded wire, it is whole to consist of a cross column foot, by symmetrically arranged L shaped baffle component being fixedly connected with in cross column foot overall peripheral, can piece together the body structure that forms four right angle types, to wherein filling the mass such as soil, sand or rubble and after the top of column foot integral body suppression ballast member, namely consisting of a kind of criss-cross prestressing force Flapper type assembly unit prefabricated reinforced concrete tower crane.
The utility model is to be formed by a cross pier side end member, some word pier side end members and eight L shaped baffle component assembly groups, from heavy and light, is convenient to making, dismounting and transportation; And when dismounting, filler is landing voluntarily, need not artificial removing, has saved the man power and material.The just cross framework of symmetry centered by this tower crane, built-in concavo-convex shear key improves anti-shearing force, adopts without bonding underrelaxation steel strand tension and is assembled into column foot integral body, and anti-basic slippage ability is strong, the resistance to capsizing isotropism; The stability of tower crane and highly versatile, rigidity is large, and high life has effectively overcome the shortcoming on existing assembling tower crane basis, applicable to polytype tower crane.
