Abstract

PURPOSE:To provide the lighter and simpler partition between a turbine building and other building and to improve the ease of maintenance thereof by adopting a moving partition by a stationary panel and moving panel system to the above- mentioned partition. CONSTITUTION:The stationary panel 8 is constituted of a member such as lightweight plastic and is supported by the outside wall and concrete wall 7a of the turbine building or the other building. The moving panel 9a is disposed in a moving section of crane and turbine parts. A monorail 10 is mounted to the lower side of a roof truss 4 as the moving mechanism of this panel 9a and, therefore, there is no increase in the building height. Moving of the panel 9a to open and close the same is enabled by the moving force of the overhead crane 3 when the crane 3 moves to the other building. The lighter and simpler partition is thus obtd. and the restrictions on the tentative placement of the turbine parts are decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a power plant building structure related to an improvement of a partition structure between a turbine building and a heteronomic layer.

(Prior Art) A power plant building structure will be described with reference to FIGS. 5 to 7, taking as an example a conventional partition structure between a turbine building and other buildings.

A turbine/generator 2 is housed in a turbine building 1, and an overhead crane 3 is installed below a roof truss 4.

Since the overhead crane 3 moves the turbine disassembled parts to the heteronomous layer 5, crane rails 6 are installed in the turbine building 1 and the heteronomous layer 5. As for the partition structure between the turbine building 1 and the heteronomous layer 5, the passage area for the overhead crane 3 and moving parts is divided into movable upper and lower parts 737b, and the lower part of the upper and lower doors 7b is partitioned by a fixed concrete wall, a fixed panel, etc. ing.

The purpose of the partition here is to prevent dust and debris from flowing into the heteronomous layer 5 from the turbine building 1, and in the case of an atomic coupler, to prevent the inflow of radioactive dust and debris. Prevent 1. The purpose is also to avoid the spread of radioactive contamination.

By the way, since the upper and lower doors 7b require hydraulic jacks or the like to open and close, they require frequent maintenance, have a complicated opening/closing mechanism, and are not easy to maintain since they are installed at a high location.

Further, since the fixed panel 8 installed at the lower part of the upper and lower doors 7b is fixed by the supporting member 9c, the supporting member 90 cannot be effectively used as a temporary storage place for the turbine disassembled parts.

(Problems to be Solved by the Invention) As described above, in conventional partition structures, the maintainability of partition members is poor, and in open/close type partitions, the structure is complicated and expensive.

Further, the support member attached to support the fixed partition imposes restrictions on the temporary placement of turbine components.

The present invention has been made in consideration of these points, and aims to provide a power plant building structure that simplifies the partition structure and improves maintainability, economy, and periodic turbine inspection. purpose.

[Structure of the invention] (Means for solving problems) In order to achieve the objectives set forth in the following, the present invention:

An overhead crane rail for turbine disassembly will be installed from the turbine building to the adjacent building, and the partition in the range of crane operation and shipping movement between this turbine building and the adjacent building will be a movable partition, and the openings in other areas will be fixed. The rooms are divided by ceremonial partitions.

Provides a power plant building structure characterized by:

(Function) In the power plant building structure configured in this way, the movable partitions using fixed panels and movable panels can be used to partition the turbine building and other buildings, making the partitions lighter and simpler. This makes it possible to improve maintainability.6 Furthermore, for temporary placement of turbine parts,
Restrictions from the partition structure can be eliminated.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIGS. 1 and 2 are diagrams showing an embodiment between a turbine building and another building according to the present invention.

Note that the same members as those in the conventional device are given the same reference numerals and detailed explanations will be omitted.

The concrete wall 7a is installed for the purpose of supporting the fixed panel 8 and for the purpose of protecting workers in other buildings from radiation from the turbine 2, and its height is approximately 5 m higher than the height of the turbine.

The fixed panel 8 is made of a material such as light and warm plastic, and is supported by the outer wall of the turbine building or another building and the concrete wall 7a.The movable panel 9a is arranged in the moving part of the crane/turbine parts. . As a moving mechanism for this moving panel 9a, a mole rail 10 is attached under the roof truss 4, so there is no increase in the height of the building.

When the overhead crane 3 moves to another building, the moving force of the overhead crane 3 allows the moving panel 9a to be moved and opened/closed.

3 and 4 show other embodiments in which the movable panel 9b is moved on the crane rail 6.
The moving panel in Figures 2 and 2 can be used to delete the blind mall. Furthermore, a support member 9c is installed on the movable panel 9b to prevent it from wobbling and falling.

With the above structure, the partition can be made lightweight and simple, and restrictions on temporary placement of turbine components can be reduced.

〔Effect of the invention〕

According to the power plant building structure according to the present invention, the structure of the partition can be made lightweight and simple, there is no need for supporting members for fixed panels, the maintainability of the movable partition can be improved, its opening and closing speed can be increased, and it is inexpensive. It can be made into a partition structure.

Moreover, from the above, it is possible to eliminate restrictions on the temporary placement of turbine components.
