A cantilever unloading platform with a pull-out channel and its construction method

Abstract

The invention discloses an overhanging discharging platform with a drawing type channel and a construction method, and belongs to the technical field of building construction safety. The overhanging discharging platform with the drawing type channel comprises main beam channel steel, secondary beam channel steel assemblies and a fixed platform plate, wherein the main beam channel steel is fixed ona corresponding floor through embedded bolts, channel steel positioning clamps, hanging rings and steel wire ropes; the secondary beam channel steel assemblies are fixedly mounted on the side, far away from the floor, of the main beam channel steel; and the fixed platform plate is welded and fixed on the upper parts of the secondary beam channel steel assemblies. According to the overhanging discharging platform with the drawing type channel and the construction method, a platform framework is arranged to be of a drawing detachable splicing type structure, construction outer frame vertical rods can be avoided in the platform erecting process, and rapid mounting of the platform channel is realized; and compared with a traditional wood mold platform, the turnover efficiency of materials isgreatly improved, the loss of wood materials and dust and noise pollution generated in the machining process are reduced, and the advantages of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of construction safety, and in particular relates to a cantilever unloading platform with a pull-out channel and a construction method. Background technique [0002] At the building construction site, the vertical transportation of materials during the construction phase of the main structure is generally transferred by tower cranes, and the unloading platform is a transfer station for material transportation; the traditional unloading platform channel needs to cut templates, lay square timber, and nail it. Installation, The demolition operation is cumbersome and inefficient, and the platform channel is made of wooden molds and square logs, which need to be cut by machinery, causing dust and noise pollution, low turnover utilization rate, waste of materials and not energy-saving and environmentally friendly; in addition, the sides of the channel, the outer frame There are not small gaps between the platform ...

[0002] At the building construction site, the vertical transportation of materials during the construction phase of the main structure is generally transferred by tower cranes, and the unloading platform is a transfer station for material transportation; the traditional unloading platform channel needs to cut templates, lay square timber, and nail it. Installation, The demolition operation is cumbersome and inefficient, and the platform channel is made of wooden molds and square logs, which need to be cut by machinery, causing dust and noise pollution, low turnover utilization rate, waste of materials and not energy-saving and environmentally friendly; in addition, the sides of the channel, the outer frame There are not small gaps between the platform and the outer frame and the building. During the unloading operation, there is a safety hazard of falling from a height; and the existing assembled platform cannot solve the problem of the position of the unloading platform and the construction outer frame. interference problem
