Embodiment

[0034] Example: such as Figure 1-6 As shown, the steel structure roof integrated with bifurcated column and curved surface grid and its installation method include the following steps:

[0035] Step 1: Define the middle area of ​​the steel structure roof as Area A, one side of Area A is followed by Area B and Area C, the other side of Area A is Area D, and the lotus valley column component 4 is located in Area A and Area B The connection is the E area;

[0036] Step 2: Prepare the layout of the lifting bracket 1 in area A, and then assemble and lift the supporting column assembly 3 in area A. The connection support of grid frame 2. Two adjacent bifurcated columns 8 are supported by connecting rods 7 with staggered teeth.

[0037] Step 3: Lift the surrounding roof grid 2 for the first time by lifting the bracket 1 to the height of the bifurcated column 8, and connect the surrounding roof grid 2 and the bifurcated column 8 through the support column edge-sealing truss 6 Com...

Abstract

The invention relates to a forked column and curved surface grid integrated steel structure roof and an installation method thereof, and belongs to the technical field of steel structures. The steel structure roof comprises a plurality of lotus grain column assemblies which are distributed in a rectangular array at equal intervals; the lotus grain column assemblies are arranged on one sides of the lotus grain column assemblies; peripheral roof net racks are arranged between the lotus grain column assemblies and between the lotus grain column assemblies and the lotus grain column assemblies; each lotus grain column assembly comprises a supporting column; a plurality of forked columns are arranged between the two ends of the supporting column and the peripheral roof net racks; supporting column edge sealing trusses are arranged between the forked columns and the peripheral roof net racks; each lotus grain column assembly comprises a lotus grain column; and lotus grain column edge sealing trusses are arranged between the lotus grain columns and the peripheral roof net racks. The forked column and curved surface grid integrated steel structure roof has the characteristics of good structural stability, short construction period and high efficiency. Therefore, construction potential safety hazards are reduced, and installation convenience is improved.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a steel structure roof integrated with bifurcated columns and curved grids and an installation method thereof. Background technique [0002] With the continuous emergence of grid structures with large spans, large areas, and more complex shapes, traditional construction methods have gradually been unable to meet the existing construction needs in terms of construction cost, construction safety, and construction efficiency. Therefore, constantly seeking more advanced construction methods and keeping pace with the times has always been an important goal that cannot be changed in the construction industry. [0003] A certain roof adopts the structural system of curved surface welded ball net truss + truss, its maximum length is about 468.8m, its maximum span is about 310m, the total projected area of ​​the roof is about 115,000 square meters, and the elevation of the highes...
