Grid-type formwork supporting and operating platform for construction of water tank on top of inverted-cone water tower

Abstract

The invention relates to a construction device, in particular to a grid-type formwork supporting and operating platform for construction of a water tank on the top of an inverted-cone water tower. The grid-type formwork supporting and operating platform is characterized in that a steel-pipe derrick is erected at the center of a cylinder of the water tower, a girder of the derrick is 5 m higher than the top of the water tank of the water tower, an inverted-cone steel grid is mounted around a ring joist of the water tank, suspending ends of a main truss of the grid are connected with a ring beam outside the girder of the derrick through steel wire ropes, and thus, the stable and safe overhead cast-in-situ water tank formwork supporting system and operating platform are formed. By the grid-type formwork supporting and operating platform which is mainly used for construction of the water tank on the top of the inverted-cone water tower, difficulty in construction of the inverted-cone water tower is overcome, and problems of long construction period, low construction efficiency, high equipment investment cost and the like in the prior art are solved.

Description

Technical field [0001] The invention relates to a building construction device, in particular to a grid type formwork supporting operation platform for the construction of an inverted cone water tower top water tank. Background technique [0002] The reinforced concrete inverted cone water tower is composed of the water tower body and the inverted cone water tank on the top of the tower. Due to the high water tower, the diameter of the top water tank is much larger than the diameter of the part of the tower body, which exceeds the specification when using ordinary scaffolding Adequate erection height poses safety risks. The existing construction method is: first complete the construction of the water tower body, and then prefabricate the water tank on the ground, and then use hydraulic lifting technology to lift the water tank to the top of the tower and fix it in place. This construction method needs to wait for the prefabrication of the water tank to be completed, and then use...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of difficult construction of reinforced concrete water tower water tank, long construction period, high equipment investment and high cost, and provide a grid-type formwork support operation platform for the construction of the water tank on the top of the inverted conical water tower. In order to realize the direct cast-in-place construction of the water tank on the top of the water tower body, eliminating the need for overall lifting construction and simplifying the construction process
