Technical Field

[0001] The invention relates to the technical field of steel structures, and in particular to a reusable special-shaped steel structure assembly platform and a construction method thereof. Background Art

[0002] As the popularity of prefabricated buildings continues to increase, special-shaped steel structures have also been widely adopted. The assembly of steel structure components requires the use of an assembly platform to ensure assembly accuracy. The assembly of large and special-shaped components generally adopts the horizontal assembly method, that is, the center line, end position line, contour line and other reference lines of the component are drawn on the platform according to the drawings, and the assembly support frame is fixed at the corresponding position. Then, the elevation line is drawn on the assembly support frame to determine the height position of the corresponding node when the component is horizontal.

[0003] Since the shapes and sizes of special-shaped steel structure components are basically different, the support frame is welded and fixed on the platform. After each component is assembled, the support frame needs to be cut off and the platform needs to be polished. When assembling the components again, the support frame material needs to be reprocessed and the support platform needs to be built according to the layout drawings. After the component welding is completed, the support platform needs to be rebuilt for inspection. Summary of the invention

[0004] The present invention mainly solves the deficiencies existing in the prior art and provides a reusable special-shaped steel structure assembly platform and a construction method thereof, which has the advantages of compact structure, convenient disassembly and assembly, high structural strength and good structural stability. Bolt holes are pre-set on the platform, and the support seat is fixed to the corresponding position on the platform by bolts according to the component layout. The height of the support seat is adjusted to determine the height and position of the positioning component nodes and components. It has the function of repeated disassembly and assembly, and the height is adjusted by adjusting the bolts to achieve control of assembly accuracy and rapid positioning.

The long slot holes 15 and the bottom plate bolt through holes 13 are adjusted and connected and fixed by bolts and nuts. The bottom plate bolt through holes 13 and the pad bolt through holes 14 are both "cross" structures, which are convenient for moving and adjusting the horizontal position according to the layout position.

[0027] The support seat assembly 2 includes a support column 10, an adjustment screw 7 movably connected to the support column 10 is provided on the upper part of the support column 10, and a support plate 8 is provided on the upper end of the adjustment screw 7. An adjustment nut 9 threadedly connected to the adjustment screw 7 is provided on the upper end of the support column 10, and a bottom plate 12 welded and fixed to the support column 10 is provided at the lower end of the support column 10. Bottom plate bolt through holes 13 are provided on the four corners of the bottom plate 12 and are bolted and fixed to the platform threaded holes 6. Four rib plates 11 are arranged between the outer periphery of the lower part of the support column 10 and the bottom plate 12 and are distributed in an annular manner with equal spacing.

[0028] A construction method for a special-shaped steel structure assembly platform includes the following steps: Step 1: Position layout is performed on the operating platform 5 according to the support horizontal position requirements and support height position requirements of the special-shaped component 1 and the steel structure component 3.

[0029] Step 2: Place the support seat assembly 2 at the layout position, and use bolts and gaskets to connect and fix the bottom plate bolt through hole 13 on the bottom plate 12 and the platform threaded hole 6 to achieve horizontal position positioning adjustment. The bottom plate bolt through hole 13 is processed into a "cross" hole groove, and the support seat assembly 2 is adjusted for front, back, left, and right displacement according to the layout position.

[0030] When the displacement adjustment of the bottom plate bolt through hole 13 cannot match the platform threaded hole 6, a transition pad 4 is added between the support seat assembly 2 and the operating platform 5. The pad bolt through hole 14 on the transition pad 4 is connected and fixed with the platform threaded hole 6 by bolts and washers, and the bottom plate bolt through hole 13 is connected and fixed with the long slot hole 15 by bolts and nuts; the horizontal displacement adjustment capability is increased by the bottom plate bolt through hole 13, the pad bolt through hole 14 and the long slot hole 15.

[0031] Step 3: According to the support height position, the adjustment screw 7, the adjustment nut 9 and the support column 10 structure are used to adjust the height size of the adjustment screw 7 and the support column 10 by rotating the adjustment screw 7 on the adjustment nut 9 in the forward and reverse directions.

[0032] Step 4: hoist the special-shaped component 1 and the steel structure component 3 onto the support seat assembly 2 for assembly, and then complete the welding process.

[0033] After the assembly of the special-shaped component 1 and the steel structure component 3 is completed, and the components are assembled and welded back to the platform for inspection, it is only necessary to adjust the corresponding position of the support seat assembly 2 according to the layout drawing, which is convenient and fast, and also saves the cost of remaking the support seat assembly 2.

[0034] In summary, the reusable special-shaped steel structure assembly platform and its construction method have the advantages of compact structure, convenient assembly and disassembly, high structural strength and good structural stability. Bolt holes are pre-set on the platform, and the support seat is fixed to the corresponding position on the platform by bolts according to the component layout. The height of the support seat is adjusted to determine the height and position of the positioning component nodes and components. It has the function of repeated assembly and disassembly, and the height is adjusted by adjusting the bolts to control the assembly accuracy and quickly position.
