Embodiment Construction

[0045] Examples see Figure 1-10As shown, this prefabricated variable steel truss platform is supported on the core tube 1 and is formed by fixed connection of steel trusses. The main truss 2 is composed of the main truss standard section 5 and the main truss shaft node standard section 7 through the gusset plate 6 with screw holes and bolts. The secondary truss 3 It is formed by detachable connection of the sub-truss standard sections 8 one by one, and the sub-stress truss 3 is detachably connected between two main stress trusses, and the struts 4 between the trusses are detachably connected in parallel Between two main truss standard sections, between two parallel secondary truss standard sections, and between parallel main truss standard sections and secondary truss standard sections.

[0046] see Figure 4-6 , the main truss standard section 5 includes a main truss upper chord 5.1 with a screw hole at the end, a main truss lower chord 5.2 with a screw hole at the end and...

Abstract

The invention relates to an assembly type variable steel girder platform, a distribution method and an assembly method thereof. The platform is supported on a core tube, and is formed by sectional steel grinders through being fixedly connected, and the sectional steel grinders mainly consist of main stress grinders, sub stress grinders and support rods between grinders, wherein the main stress grinders are formed by main grinder standard nodes and main grinder groined node standard nodes through being dismountably connected via node plates with bolt holes, end sealing plates with bolt holes and screw bolts, the sub stress grinders are formed by sections of sub grinder standard sections through being dismountably connected end to end, and in addition, the sub stress grinders are dismountably connected between two main stress grinders. The platform can be applied to template lifting construction of high and superhigh building core tube steel platforms, and can also be used as platforms for large-area spanning construction operation and construction machine pile carrying and placement, the construction is very easy, the work period of the construction is greatly accelerated, and the construction cost is reduced.

Description

technical field [0001] The invention relates to an assembled steel platform placed on a core tube of a high-rise or super high-rise building, and an arrangement method and an assembly method thereof. Background technique [0002] The existing high-rise and super-high-rise building core tube hoisting formwork construction platform is a space steel truss platform, which is welded and connected by section steel. The shape of the platform is designed according to the shape of the core tube of the building under construction. Hangers and The formwork can be used for stacking, placing construction machinery, and arranging walkways. Since the existing space steel truss platform is welded and connected by section steel, the welding process is cumbersome and complicated. It is welded and needs to be destructively disassembled after use. It cannot be reused and can only be discarded, so a lot of materials will be wasted and construction costs will be increased. Contents of the inve...
