Preferably, the umbrella-shaped bracket includes a tubular first bracket, a plurality of mounting surfaces are evenly arranged on the outer circumferential wall of the first bracket, the second bracket is fixed on the installation surface, and an arc-shaped installation is fixed between adjacent second brackets The multi-segment arc-shaped mounting plate forms a circular ring-shaped mounting plate.

Preferably, the column standard section includes a tubular body, the upper and lower end surfaces of the tubular body are provided with annular connecting surfaces, and a reinforcing block is arranged between the tubular body and the annular connecting surface.

The second technical scheme of the present invention is: a construction method of a Bailey steel truss support device for shallow round warehouse construction, comprising the following steps:

1) A central support column is erected on the ground, and the bottom of the central support column is reinforced by a cable wind rope;

2) The tower crane is used to hoist the combined beret, the horizontal rod at one end of the combined beret is connected with the umbrella-shaped bracket of the central support column by bolts, and the installation part of the horizontal rod at the other end is placed in the hole in the warehouse wall; the combined beret There are a plurality of them, which are evenly wound between the center support column and the warehouse wall;

3) After the installation is completed, check the flatness of the combined beret and the verticality of the center support column.

The Bailey frame described in the present invention is also called "assembled highway steel bridge", formerly known as "321" highway steel bridge. Bailey frame is a steel frame that forms a certain unit, which can be spliced and assembled into many components and equipment.

The invention is used to build the roof of the shallow round warehouse, the central supporting column stands at the center of the shallow circular warehouse, the multiple combined berets are evenly installed around the central supporting column, and the horizontal rod at one end of the combined beret is fixed on the central supporting column The installation part of the horizontal rod on the other side is anchored into the warehouse wall, so as to complete the overall construction of the Bailey beam truss.

In the present invention, the beret originally used for the construction of bridge engineering is used in the construction of the roof of the shallow round warehouse. Quick, after use, it can be disassembled and turned around for reuse.
