Abstract

PURPOSE:To mutually connect pipings accurately and easily by forming a piping to be fitted extending over two faces opposing in parallel of a module frame in minus accuracy against a distance between the two faces, and providing a bent pipe in the other module frame. CONSTITUTION:When a piping 11 arranged extending over between faces A, B opposing in parallel of a module frame 1 forming an imaginary hexahedron is outfitted to the module frame 1, the piping 11 is cut so as to be same as the length L1 of the imaginary hexahedron or a little short length L2, and fitted. Meanwhile, the other module frame 1' connecting to the module frame 1 in the lengthwise direction of the piping 11, is provided with a bent pipe 14, for example, bent in the 90 deg. direction against the lengthwise direction of the piping 11. In this way, mutual connection of pipings of the module frames is prevented to become impossible, dimensional error between the piping and the module frame can be absorbed by bending of the bent pipe, and hence loading work of the module frame on board a ship is facilitated and construction period is remarkably shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of manufacturing a piping part to a module frame.

[Prior Art] In the engine room of a ship, a wide variety of rattan products such as equipment, piping, wiring, etc. are installed and fixed on the hull structure, and usually after the deck of the hull structure is constructed, The rattan products to be installed on the deck are carried onto the hull structure or into the engine room and installed.
I'm trying to fix it.

However, with the above conventional method, there is a large amount of work to be done on the ship, such as installation and adjustment, and the work is done in a bad environment, resulting in low work efficiency and lengthening of the construction period. Installation and fixing operations involve a large number of adjustments due to dimensional errors, which further reduces work efficiency.

One way to solve these problems is to divide the rattan products into multiple blocks and attach them to module frames in advance at a factory, then transport the module frames together with the rattan products onto the ship, install them, and then add other rattan products. A possible mounting method would be to transport the installed module frame and connect the module frames and the rattan products.

With this method, the monoyl frame, which is manufactured with relative precision outside the ship and fitted with rattan products, is simply carried onto the ship and connected, which significantly reduces the amount of work required on board and shortens the construction period. can be achieved.

[Problem to be solved by the invention] However, even if the monoyl frame described above can be constructed with relatively high precision in a factory, it is difficult to attach the rattan product to the module frame and to transport the module frame into the ship. Depending on how the module is positioned during installation, dimensional errors may accumulate, requiring adjustment between the module frames and between the maintenance parts, and this adjustment requires a great deal of effort and time. It is conceivable that implementation would be difficult in practice.

In particular, if the straight pipe section of the pipe has a length spanning multiple module frames, variations in the accuracy of individual module frames and errors in the machining dimensions of the pipes will accumulate.
It is conceivable that a large gap may be created at the connecting portion due to the d-resistance, or that the connection becomes completely impossible due to the length.

In such cases, the conventional practice has been to use dowel pipes to absorb the errors, but this requires a large number of dowel pipes and increases the amount of adjustment work required onboard the ship. There is a problem that the efficiency of the project will decrease and the construction period will be extended.

The present invention was made by focusing on the above-mentioned conventional problems.
It is an object of the present invention to provide a method for manufacturing pipe rattan into a module frame, which allows pipes to be easily and precisely connected to each other without using conventional mating pipes.

[Means for Solving the Problems] The present invention forms piping to be attached between two parallel opposing sides of a module frame forming an imaginary hexahedron with a precision minus the distance between the two sides. , and at least one of the other module frames connected and arranged with respect to the module frame in the longitudinal direction of the piping is provided with a bent pipe that is bent with respect to the longitudinal direction of the piping, and the dimensional error of the piping is reduced. The present invention relates to a method for manufacturing piping rattan for a module frame, which is characterized in that the absorption is achieved by bending the target pipe.

[Function] Since the piping provided between the two parallel opposing sides of the imaginary hexahedron formed by the module frame is formed with minus precision, it is possible to prevent the piping of the module frame from becoming impossible to connect with each other and always ensure In addition, dimensional errors between the piping and the module frame can be absorbed by bending the bent pipe.

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

FIG. 4 shows an example of the basic shape of a module frame l for carrying out the method of the present invention. A beam member 3 that is integrally welded and fixed in the front and rear direction, and a beam member 1 that is integrally welded and fixed vertically below t of the joint between the main girder 2 and the beam member 3.
- section support 4 and lower support support 5.

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 allows the left side A, the right side B, the front side C1, the rear side D, and the top side E1.
An imaginary hexahedron consisting of a lower surface F is formed.

In the figure, 7 indicates an auxiliary beam added to support rattan products such as heavy equipment 8, and 3 indicates that the module frame 1 is attached to a ship's hull structure (bulkhead, etc.) when the module frame 1 is installed inside the ship. 9 is a reinforcing rib;
1o indicates a reinforcing bracket.

In addition to the equipment 8, various rattan products such as piping 11 and wiring 12 are attached to the module frame l. 13
indicates a connection portion such as a flange provided at the end of the pipe 11 for connection.

The above module frame l is constructed by assembling the main girder 2, beam members 3, upper and lower supports 4, 5, etc. into a frame shape by welding, removing welding distortion, and then accurately positioning and supporting the connecting fittings 6 and each of the above-mentioned members 2. , 3.4.5 are connected by welding, thereby making it possible to form a highly accurate imaginary hexahedron.

When the piping 11 and wiring 12 are made of rattan in the module frame 1, the wiring 12 is relatively flexible, so it is possible to easily adjust and connect the module frames 1 together. Or, in the case of straight piping [1], if it is not machined with high precision, gaps may be created or connections may become impossible.

For this reason, when taking the parallel opposing faces A, B, and C of the module frame 1 forming an imaginary hexahedron, and installing the pipes 11 that were once placed on E and F on the module frame 1, As shown in Figure 1.2, the length L is equal to or slightly shorter than the length (distance) Ll of the imaginary hexahedron.
2, the pipe 11 is cut and installed with a negative precision of, for example, 0 to -2111111.

This prevents the module frames 1 from becoming impossible to connect with each other.

On the other hand, another module frame 1° connected to the module frame 1 in the longitudinal direction of the piping 11 is bent, for example, at 90° with respect to the longitudinal direction of the piping 11, as shown in FIG. A tube 14 is provided.

When the module frame 1' having the above-mentioned bent pipe 14 is provided, even if there is an accumulation of dimensional errors due to the connection of the straight pipe 11, the above-mentioned dimension will not be corrected as shown by the solid line and broken line in FIG. Errors can be easily absorbed by bending the bent pipe 14.

It should be noted that the method of manufacturing piping rattan for a module frame according to the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

[Effects of the Invention] As explained above, the method for making piping into a module frame according to the present invention allows the piping installed in a large size between two parallel opposing faces of an imaginary hexahedron formed by the module frame to be formed with minus precision. This prevents the pipes from being impossible to connect to each other in the module frame, making it possible to connect the pipes together, and also allows dimensional errors between the pipes and the module frame to be absorbed by the bending of the bent pipe. Therefore, it becomes easier to install the module frame with the pipes installed inside the ship, and the construction period can be significantly shortened, which is an excellent effect.
