Fixing device for operation platform for shielding wall of AP1000 nuclear island

Abstract

The invention relates to a fixing device for an operation platform for a shielding wall of an AP1000 nuclear island. The device comprises a tail anchor bar. One end of the tail anchor bar is machined with a threaded section and the other end of the tail anchor bar is bent to some degree. The thread section of the tail anchor bar is fixedly connected with a sleeve. After the sleeve is connected with the tail anchor bar, the overall part is poured into the interior of the shielding wall. The other end of the sleeve is connected with a connecting rod, on which an installing plate is fixed. The installing plate is fixed with an operation platform framework. The fixing device for the operation platform for the shielding wall of the AP1000 nuclear island has following beneficial effects: due to the fact that the fixing device for the operation platform is fixedly installed into the interior of a poured wall, loads of the overall fixing device can be supported by the wall, thereby facilitating fixed installation of the operation platform and ensuring safety and stability of the operation platform; and conduction efficiency is improved and quality is ensured.

Description

technical field [0001] The invention relates to the technical field of auxiliary construction devices for nuclear island shielding walls, in particular to an AP1000 operating platform fixing device for nuclear island shielding walls. Background technique [0002] The construction operation platform used in the construction process of the existing nuclear island shielding wall mainly adopts the following structures and methods: [0003] Method 1: Set up scaffolding. For walls with small height (below 24m) and favorable construction environment, scaffolding is often used as the operating platform, and for walls with excessive height (24m and above) or walls with unfavorable construction environment, method 2 is often used. [0004] Method 2: Set up cantilevered scaffolding. For unfavorable construction environments such as large wall heights or potholes in wall accessories, the form of cantilevered steel beams is often used. The cantilevered steel beams are fixed on the cons...
