Embodiment Construction

[0037] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] combine figure 1 As shown, when adopting the method for connecting the ring-hanging rail beam and the corbel of the present invention, when the ring-hanging rail beam and the corbel are fixedly connected, the following steps are specifically included:

[0039] Step S1, after completing the high-altitude fixed installation of the corbel, directly hoist the ring-hanging rail beam to the corbel, and perform assembly and position adjustment of the ring-hanging rail beam on the corbel. Among them, by adjusting the position of the assembled ring-hanging rail beam, all the connecting holes on the ring-hanging rail beam correspond to the corbels.

[0040] In addition, the corbel is a metal component and is fixedly connected to the containment steel-lined cylinder by welding. At the same time, the backing plate of the jack base for installi...

Abstract

The invention belongs to the technical field of nuclear power construction, and in particular relates to a construction method for connecting a ring-hanging rail bearing beam and a corbel. In order to solve the problems of low construction efficiency and low connection accuracy when using the prior art to connect the ring-hanging rail beam and the corbel, the invention discloses a method for connecting the ring-hanging rail beam and the corbel. The method includes, step S1, after completing the high-altitude fixed installation of the corbel, directly hoisting the ring-hanging rail beam to the corbel, and performing assembly and position adjustment of the ring-hanging rail beam on the corbel; step S2, according to the For the position of the connecting hole on the suspension rail beam, directly drill the corresponding bolt holes on the corbel; step S3, after completing the bolt hole matching drilling process on the corbel, directly use the bolts to carry out the ring-hanging rail beam and the corbel. The connection between them is fixed. The method of the invention is used to connect the ring suspension rail beam and the corbel, which can not only shorten the construction period, improve the construction efficiency, but also improve the precision of the connection.

Description

technical field [0001] The invention belongs to the technical field of nuclear power construction, and in particular relates to a construction method for connecting a ring-hanging rail bearing beam and a corbel. Background technique [0002] The reactor building of a nuclear power plant is generally a cylindrical building, and 36 supporting corbels are evenly arranged on the steel lining inside the cylindrical building, and a ring-shaped ring crane supporting rail beam for the rotating operation of the ring crane is laid on the corbel. Wherein, a connection hole is provided on the ring suspension rail beam, and a bolt hole is provided on the corbel, so that the two are connected and fixed by bolts. [0003] At present, the steps for connecting and fixing the ring-hanging rail beam and the corbel are as follows: firstly, the ring-hanging rail beam is assembled on the ground, and the positions of all the connection holes are measured for the assembled ring-hanging rail beam. ...
