Abstract

PURPOSE:To prevent congesting works in a plant building from occurring by assembling well in advance pipings, IPBs, cable trays, supporting frames and so on of a thermal and a nuclear power systems at a place with good workability and safety, other than a final fixing place. CONSTITUTION:Pipings 2, IPBs 2, cable trays 3, supporting frames 4 and so on are assembled to a structural block at a place with good operability other than a final fixing place, and the block is fixed to holding parts provided on columns and beams of a plant building. In this occasion, congestion of works can be avoided by fixing equipments such as an electrical board 6 and so on which are arranged underneath the block, after the block is completely fixed. In this case, since a plurality of equipments are fixed after they are assembled to an integral block, shortening of work schedule resulted from an improvement of workability becomes possible and a good effect on safety aspect can be expected.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to piping for thermal power, nuclear couplants, etc.

This invention relates to a construction method suitable for installation work, especially in mixed and dense areas such as IPB.

[Conventional technology]

Until now, there has been no application that focuses on a block construction method using only permanently installed straight items such as piping, IPB, etc., and Japanese Patent Application Laid-Open No. 123087/1987 focuses on a block construction method that involves temporary construction.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the permanent product and the temporary product must be assembled together at a location other than the final installation location, and after assembly is completed, the temporary component must be moved to the final installation location, installed, and after the installation is completed, the temporary material that was necessary only during assembly must be removed. However, there were problems with stability, economy, and workability.

The purpose of the present invention is to improve safety by performing the installation work of long objects outside the plant building, where there are no restrictions on workability, by blocking only permanent parts without using any temporary parts. Economical efficiency 9 The objective is to improve work efficiency.

[Means to solve the problem]

The two-legged objective is achieved by synchronizing the block construction method design and the equipment design of Plan 1 to Building Architectural Design 2, and by moving and installing the blocks using a self-propelled lifting cart.

[Effect]

By synchronizing the block construction method design and the plant building architectural design 9 camera equipment design, the temporary supports 1 to 1 are not required, and the removal work of temporary items after the block installation is completed is not required.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. This figure shows how piping, IPB, cable trains, supports, etc. are assembled into blocks at a location other than the final installation location that is easy to operate, and then moved to the final installation location inside the plant building for installation.

Piping other than the final installation location 1. IPB2. Cape-Sitley 3. Assembling support 4 etc. into blocks Plan 1
-Move to the final installation position in the building and attach the block to the joints 5 provided on the pillars and beams of the plant building.

At this time, by installing equipment such as the electrical panel 6 located at the bottom of the block after the block installation is completed, it is possible to avoid a wide range of work.

Here, the structure of the block and its movement into the plant building will be explained with reference to FIG. The assembled block is placed on a movable self-propelled elevating cart 8 on a traveling rail 7'' provided within the plant site and moved to the bottom of the final installation position within the plant building.

Next, a method of setting blocks at the final setting position will be explained with reference to FIG. Final installation position] The block that has been moved to the bottom of 11 is moved to the final installation position by the lifting device of the self-propelled lifting cart 8, and the block is installed by attaching it to the joints 5 provided on the plant building pillars and beams. Complete.

In addition, when setting blocks, work efficiency is improved by connecting multiple blocks in advance at the final installation position, and after performing painting, heat insulation, etc., move to the final installation position 4 and attach it to the joint 5. This has the effect of shortening the construction period and improving safety.

〔Effect of the invention〕

According to the present invention, it is possible to prevent @light construction work inside the plant building, and since multiple devices can be assembled into a single block and then installed in a location with good workability, construction work associated with improved workability can be avoided. It is possible to shorten the period and has a large effect in terms of safety.
