Currently, mast climbing is used in mid-to-high-rise construction work to prevent damage caused by tower cranes. When supporting the tower crane base A with the steel beam B, a base support beam C is used between them, and the tower crane base A and the base support beam C are fixed with bolts D and metal fittings E, both ends of which are screw type. The bolt D is time-consuming and dangerous, requiring scaffolding. Therefore, there was a drawback that the scaffolding had to be assembled and dismantled for each climbing.

When supporting a tower crane base with a steel beam, which is currently used in medium-to-high-rise construction work, the method of fixing the tower crane base and base support beam with bolts and metal fittings is time-consuming because it uses bolts with threads on both ends. This invention attempts to solve the problem that scaffolding is required because it is dangerous, and therefore the scaffolding must be assembled and dismantled every time a climb is performed.

In this invention, four brackets are provided at predetermined locations on the upper surfaces of two base support beams, a bearing for pivoting a one-end pin-type fixing bolt is fixed to the upper surface of the bracket, and one-end pin-type fixing bolt is attached to each bearing. While pivoting with a pin, insert the end of the tower crane base assembled in a cross shape between the opposing bolts, raise the bolt, insert a metal fitting into the upper end of the bolt through the hole, and tighten the nut onto the bolt. This problem was solved by screwing together and firmly fixing the tower crane base to the base support beam.

Four brackets 2 are provided at predetermined locations on the upper surfaces of the two base support beams 1, and a bearing 3 for pivoting a pin-type fixing bolt at one end is fixed to the upper surface of the brackets 2.
A pin-type fixing bolt 4 at one end is pivotally attached to each bearing 3 by a pin 5, and a metal fitting 7 and the bolt 4 are provided with a hole 6 having a distance between the opposing bolts 4.
It is made up of a nut 8 that is screwed together. With the above structure, the end of the tower crane base 9 assembled in a cross shape is inserted between the opposing bolts 4 of the bracket 2 provided on the upper surface of the base support beam 1, the bolts 4 are raised, and the upper end of the bolt 4 is inserted. Insert the metal fitting 7 through the hole 6 and screw the nut 8 onto the bolt 4 to attach the tower crane base 9.
is firmly fixed to the base support beam 1. As shown in FIG. 1, the tower crane 10 passes through a base 11 fixed to the upper part of the structure, and a support member 12 is fixed to the tower crane 10.
and the support member 12 are connected by a power jack 13, and are raised by the operation of the power jack 13.
