Embodiment Construction
[0026] Examples see figure 1 As shown, a frame for concrete-filled steel tube high-throw pouring includes a tool-type steel platform 1 and a tool-type curb 2, and the tool-type steel platform and tool-type curb are used to pour concrete-filled steel tubes. The outer frame structure of the main building of this project adopts steel pipe concrete columns from the 5th floor. The inside of the steel pipe columns is self-compacting concrete. The platform and the horseway are poured with concrete filled steel tubes by hydraulic distributors.
[0027] Examples see figure 2 and image 3 As shown, the tool-type steel platform is shaped and processed. The steel platform skeleton 11 is composed of platform steel beams 13 welded by [16a channel steel and L63×5.0 angle steel. Protective railing 31 is set, and protective railing 31 adopts around 60×3.5mm and 40×3mm round steel welded, 1.5m high, protective railing 31 covered with 30×30×3.5mm steel wire mesh 32. Four lifting rings a...

The invention belongs to the field of construction equipment, in particular to a construction frame body for the high-dropping construction of a concrete filled steel tube and an application method of the frame body. The frame body comprises a tool type steel platform and a tool type packway which are distributed according to construction requirements. The method comprises the following steps: firstly, mounting steel pipe columns and correcting steel columns; secondly, mounting steel beams; thirdly, performing inspection and acceptance on the steel pipe columns and the steel beams; fourthly, mounting the tool type steel platform and the tool type packway; fifthly, performing inspection and acceptance on the tool type steel platform and the tool type packway; sixthly, mounting a hydraulic distributing machine; seventhly, casing self-compacting concrete; eighthly, dismounting the tool type steel platform and the tool type packway. By adoption of the construction frame body, trepanning and repairing welding do not need to be performed on the steel pipe columns, the construction period is shortened, labor force is saved, the construction cost is reduced, the requirement on structure construction quality can be met, and the frame body is particularly applied to construction of super high-rise concrete filled steel tubular columns.
Description
technical field [0001] The invention belongs to the field of building construction equipment, and in particular relates to a construction frame used in high throw construction of steel pipe concrete and a method for using the frame. Background technique [0002] In the construction of construction projects, the application of steel pipe concrete is more and more extensive. The traditional method of pouring steel pipe concrete mostly uses the conduit method, the pumping jacking method and the tower crane throwing method. The construction efficiency of the conduit method, the pumping jacking method and the high-throwing method of the tower crane are low, and the work tasks are heavy, and the safety of the construction personnel cannot be guaranteed. Especially in the construction process of super high-rise buildings, the outer frame structure floor is not constructed when the steel tube concrete is poured. Moreover, the tower crane cannot meet the pouring requirements. The tra...
