Pulley bracket platform with large-column-grid and large-area grid structure and construction method thereof by utilizing pulley bracket method

Abstract

The invention relates to a pulley bracket platform with a large-column-grid and large-area grid structure and a construction method thereof by utilizing a pulley bracket method. A bracket body comprises a tower bracket, a suspended span bracket and a suspended overhang bracket; two longitudinal tower brackets are connected through a cross bracket; the bottoms and the tops of two traverse tower brackets are connected with the suspended span bracket; the top of the external side of the tower bracket is connected with the suspended overhang bracket; a steel pipe arranged on the bottom end of the tower bracket is sheathed on a pulley, and the axis of the steel pipe coincides to the axis of the pulley; the pulley is arranged on a guide rail; a sleeper is laid below the guide rail, and the sleeper and the guide rail are fixed in a spot welding mode; a pulley is arranged on the bottom surface of the pulley bracket platform; and the shift of a construction platform is realized by shifting the pulley. Compared with the traditional scaffold, the invention the advantages that the erecting amount and the dismantling of the scaffold can be reduced; the problems of overlarge deflection value and overlarge displacement deviation of a grid bracket to be erected because of overlarge integral settlement of a construction bracket are simultaneously avoided and can be widely applied to the installation and the construction of the large-column-grid and large-area grid structure.

Description

technical field [0001] The invention relates to a construction platform installed with a steel net frame, in particular to a sliding frame platform with a large column net and large area grid structure and a construction method of the sliding frame method. Background technique [0002] Usually, the grid construction adopts the construction methods such as the high-altitude bulk method, the hoisting method, the overall lifting method, and the grid sliding method. If the tonnage is too large, common quality problems such as excessive overall settlement of the support, excessive grid deflection, and large displacement deviation will often occur. Moreover, the above-mentioned methods often result in a relatively long construction period due to the long construction time of auxiliary construction facilities. long, resulting in high project cost.
