Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figure 1, a vertical member replacement device for high-rise building floors includes an upper column-holding beam 2 arranged on a vertical member column 1 on the N+1 floor, an upper column beam 2 arranged on the N-1 floor The lower column-holding beam 3 on the vertical member column, the prestressed support column arranged between the upper column-holding beam and the lower column-holding beam, and the preset jack 5 arranged between the prestressed support column 4 and the upper column-holding beam . In the same vertical component replacement device: the upper column-holding beam and the lower column-holding beam are located on the same vertical component column of the building.

The prestressed supporting columns are vertically arranged. The lower end of the prestressed support column goes down through the floor slab of the Nth floor, and the lower end of the prestressed support column is provided with a horizontal lower connecting end plate 7 . The upper end of the prestressed support column goes upwards through the roof slab of the Nth floor, and the upper end of the prestressed support column is provided with a horizontal connecting end plate 8 .

A lower anchor bolt 6 is buried on the upper surface of the lower column-holding beam. The lower end of the prestressed support column is connected to the lower column-holding beam, specifically, the lower end of the prestressed support column is connected to the lower column-holding beam through the horizontal lower connection end plate and the lower anchor bolt, and the horizontal lower connection end plate and the lower anchor Bolt connected.
