Abstract

PURPOSE:To shorten construction period by deciding a fitting position of an equipment against a module frame from one point due to the origin of right/left and ahead/astern and the reference point in the up and down direction. CONSTITUTION:At fitting equipment 8, 12, 13, by being consistently due to the origin X of right/left and ahead/astern and reference points Y1, Y2 of up/ down, all equipments 8, 12, 13 and connecting parts 14 can be accurately positioned and fitted. Further, when a module frame 1 fitted with the equipments 8, 12, 13 is loaded on board a ship, the origins X of respective module frames placed on the bow side and the hull center side of an engine room of a ship are arranged in order so as to conform to the installation planning point of the ship, and hence accumulation of dimensional error of respective module frames 1 can be prevented. Hereby, position adjustment between module frames 1 and between the equipment 8, 12, 13 at loading on board the ship is eliminated, and construction period at loading on board the ship can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for attaching equipment to a module frame.

[Prior Art] In the engine room of a ship, a wide variety of equipment, piping, wiring, and other fittings are installed and fixed on the hull structure, and are usually installed after the deck of the hull structure is constructed. The equipment installed on the deck is carried into the engine room, installed and fixed.

However, in the conventional method described above, there is a large amount of onboard work such as installation, and the work is done in a place with a poor environment, resulting in low work efficiency and an extended construction period.
Furthermore, during the installation and fixing work inside the ship, there is a problem in that a large number of adjustments are required due to dimensional errors, which further reduces work efficiency.

A method to solve these problems is to divide the equipment into multiple blocks and attach them to the module frame in advance at a factory, etc., then transport the equipment together with the module frame onto the ship, and then install the equipment on board the ship. A mounting method is conceivable in which the module frames with attached module frames are carried in and the module frames and fittings are connected to each other.

This method has relatively high precision outside the ship (as the module frames that have been fabricated and fitted with the equipment are simply carried into the ship and connected, the work inside the ship is significantly reduced and the construction period is shortened). It is possible to shorten the time.

[Problem to be solved by the invention] However, even if the above-mentioned module frame can be constructed with relatively high precision in a factory, attaching fittings to the module frame is a laborious task, and requires a lot of work and time onboard the module frame. Depending on the positioning method used when mounting the module, dimensional errors may accumulate, requiring adjustment between module frames and fittings, and this adjustment requires a great deal of effort and time. It is conceivable that it would be difficult to implement in practice.

The present invention has been made in view of the above-mentioned points, and provides a module frame that allows for the attachment of external components to the module frame with high precision, and at the same time allows the mounting of the module frame inside a ship with high precision. The purpose is to provide a method for installing fittings to.

[Means for Solving the Problems] The present invention provides a module frame that is assembled to form an imaginary hexahedron, and a point on the module frame on the ridgeline formed by the bow side and the center side of the hull of the imaginary hexahedron. The origin of left and right, front and rear, and one of the top and bottom surfaces of the imaginary hexahedron.
This method involves positioning and mounting the fittings and their connecting parts using points as reference points in the vertical direction.

[Function] Since the mounting of the equipment to the module frame is determined from a single point based on the left, right, front, and rear origin points and the vertical reference point, the occurrence of dimensional errors within each module frame is minimized. It can be suppressed. Further, by positioning and mounting each module frame in the ship with reference to the origin, it is also possible to prevent dimensional errors of the module frames from accumulating.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the basic shape of the module frame l used in the method of the present invention. It includes a beam member 3 which is welded and fixed together in the direction, and an upper support 4 and a lower support 5 which are integrally welded and fixed vertically above and below the joint between the main girder 2 and the beam member 3.

A flange-shaped connecting fitting 6 is attached to each end of the module frame 1, and the outer surface (connecting surface) of the connecting fitting 6 forms an imaginary hexahedron as a whole.

In the figure, 7 is an auxiliary beam added to support equipment such as heavy equipment 8, and 3 is an auxiliary beam added to support fittings such as heavy equipment 8, and 3 is the module frame 1 that is attached to the hull structure of Figure 2 when the module frame 1 is installed inside the ship. (bulk head etc.) an extension part for connecting and restraining 9, 10

In addition to the equipment 8, various fittings such as piping 12 and wiring 13 are attached to the module frame l. I4

The module frame 1 is constructed by assembling the main girder 2, beam members 3, upper and lower supports 4.5, etc. into a frame shape by welding, and after removing welding distortion, connecting fittings 6 and each of the above-mentioned members 2 are precisely positioned and supported. , 3, 4.5 are connected by welding, thereby forming a highly accurate imaginary hexahedron.

When attaching the equipment 8, 12, 13 to the module frame 1, one point of the connecting fitting 6 is located on the ridgeline 18 formed by one end surface in the left and right direction and the side surface in the front and rear directions of the imaginary hexahedron. (for example, the center) is the left and right, front and rear origin X, and the above-mentioned equipment LI2, 13 is

When the module frame [with the above-mentioned equipment 8, 12, 13 attached] is installed in the ship, the ship 15 is installed as shown in Fig. 2.
By sequentially arranging each module frame 1 such that the origin X of each module frame 1, which is located on the bow side of the engine room 16 and the hull center 17 side, coincides with the planned installation point of the ship 15, each module frame 1
It is possible to prevent dimensional errors from accumulating.

Therefore, the space between the module frames 1 and lI when installed onboard the ship.
