[0020] Reference Figure 1-2 As shown, this embodiment provides a temporary fixing device for vertical pump pipes in high-rise buildings, the fixing device is used between two adjacent upper and lower floor slabs 1, the upper floor slab 1 and the lower floor slab 1 are both provided with steel pads 2, a circular hole is penetrated through the middle of the steel pad 2, the pump pipe 7 passes through the circular hole to connect the upper and lower floor slabs 1, the fixing device includes four groups of support frame uprights 6 and a transverse tie rod group, the four groups of support frame uprights 6 are vertically supported on the upper and lower groups of steel pads 2, and the four groups of support frame uprights 6 are distributed in a rectangular shape around the pump pipe 7, and the transverse tie rod group is connected to the four groups of support frame uprights 6 through vertical fasteners 10.

[0021] By arranging support frame uprights 6 around the pump pipe 7 and arranging a transverse tie rod group on the support frame uprights 6, the overall transverse stiffness of the support frame uprights 6 is enhanced, and the pump pipe 7 is also limited at the same time, that is, the displacement of the pump pipe 7 due to vibration during the pouring process is limited, thereby preventing the floor 1 from colliding with the pump pipe 7 and being damaged during the process of pumping concrete.

[0022] Furthermore, the tops of the four groups of support frame uprights 6 are internally threadedly connected with telescopic rods 5 .
