GB7386.287
This standard is applicable to the structural dimensions and component positioning required in the dimension coordination of ship accommodation plans. This standard is formulated with reference to S03827/1-1977 "Shipbuilding-Dimension Coordination of Ship Accommodation Cabins-Part 1: Principles of Dimension Coordination" and S03827/V-1.977 "Shipbuilding-Dimension Coordination of Ship Accommodation Cabins-Part 4: Control Dimensions". This standard recommends a dimension structure system as the basis for deriving the coordinated dimensions of components. Control datum system
According to needs, several known control lines are marked in the structural system, and the bottom surface represented by these control lines divides the structural system into several usable spaces (such as cabin interiors) and areas. The main dimensions of these areas and usable spaces can be controlled, and the control dimension should be based on the standard modulus shown in the table in GB7386.1, and its modulus series should also be controlled to provide a limited size series.
1.1 Control lines and reference planes
t.1.1 Control lines
Control lines are used to indicate the position of items such as panels, ceilings, walls, etc., as shown in Figure 1.99
1.1.2 Upper reference plane
The upper reference plane is a two-dimensional surface shown on half-planar drawings, end views, etc. 1.1.2.1 The upper reference plane is a two-dimensional surface related to bulkheads, linings, room enclosures, etc. Figure 2

1.1.2.2 Horizontal principal datum planes
Horizontal principal datum planes are non-linear planes related to horizontal surfaces such as floors, decks, ceilings, etc., as shown in Figure 3. Figure
t.2 Areas and spaces
The purpose of drawing principal datum planes in a structural system is to divide the structural system into several areas and available spaces. If the main dimensions of these areas and available spaces are modulo-coordinated, a modular datum system is obtained, in which modular components can be arranged. 1.2.1 Controlled areas
Controlled areas are spaces with coordinated dimensions that are used for assembling components but are not necessarily filled. In principle, facing layers, insulation, thermal insulation, and water and electricity pipelines and their accessories are usually placed in this area, as shown in Figure 4.09
1.2.2 Available spaces
The available space is bounded in the vertical direction by the complete floor and ceiling surfaces above, and in the horizontal direction by the horizontal surface of the floor and ceiling. For a cubicle, the complete surface of the bulkhead or lining is the limit, as shown in Figure 5.
.1.2.3 Control Dimensions
GB 7386.2-87
The control dimension should be the main dimension of the coordinated cubicle, and its value should be selected according to CB7386.111, as shown in Figure 69bZxz.net
Determination of Control Lines
When the control basis is used for cabin design, there are many methods to determine the control line. 2.1 Control Line Located on the Area Limit (First Method)0
The control line is marked on the area limit, that is, on both (surfaces) of the area, as shown in Figure 7. Figure 7
W.GB 7386.2-87
This method is most suitable for use in the initial cabin area, especially in those cabins where the equipment arranged is repeated. For example, similar living cabins.
The control line is set on the area limit, and its angle is measured on the area interface, so that the available space for arranging components is directly related to the control size, and has nothing to do with the size of the wind zone. In practical application, this method can locate components with similar dimensions to those of adjacent walls, linings, etc. within the available space, without the need to configure additional accessories or fillers to compensate for changes in the width of the area, including structures such as shelters, as shown in Figure 8: 2.2 Control line located on the center line of the area (second method) Figure 8
The control line is generally marked on the center line of the area, as shown in Figure 9, but it can also be placed at any position in the area. Figure
This method can be used to locate the area. If the width of the area changes due to structural reasons such as cabin walls and linings, it is necessary to configure special accessories or fillers to apply modular components. 2.3 The above two methods can be combined and used as needed to maximize the use of modular components. 3 Determination of Controlling Dimensions
The design of the midship and accommodation cabins of the ship can be used to derive the coordinated dimensions of the components, which can serve as a guide for the coordinated dimensions of the selected components.
When selecting the controlling dimensions, reference should be made to the relevant national or international standards or regulations to ensure the requirements for the specific ship. 3.1 Vertical Controlling Dimensions
The vertical controlling dimensions refer to the vertical distance from the plate to the ceiling and the connection between the components or assemblies, as shown in Figures 1 and 11.
GB7386.2—87
In order to make full use of the coordinated components, it is best to use a half-surface structure, that is, a flat deck, and eliminate the deck and (or) beam arch as much as possible. When there is a glare and (or) a beam arch, its influence on the height of the ceiling and other aspects should be considered to achieve the maximum modular coordination. 3.1.1 The control octave of the deck to the height of the dog board is the net height between the cut lines on the boundary of the finished floor to the ceiling area (that is, the vertical distance from the upper surface of the finished floor to the ceiling or the lower edge of the accessories such as pipelines), as shown in Figure 10. The preferred dimension of the height 4 from the board to the large board is 2100mm, and other height values that are integer multiples of 100mm or 50mm can also be selected. When determining the height of the modular deck ceiling, the deck height H should be fully considered according to actual conditions, and the height of the deck structure, finishing layer, pipeline accessories and ceiling areas should be reserved to ensure that the height from the deck to the ceiling meets the coordinated dimensions. 3.1.2 The vertical control dimensions of the upper edges of windows, glazing windows, door frames, and the lower edges of windows and windows refer to the vertical control dimensions of the finished deck. The height above the horizontal control surface of the floor, as shown in Figure 11. For windows and glazings, these dimensions will determine the door opening position of the window frame installed on the lining, rather than the position of the window itself.
The preferred height of the control line at the lower edge of the window or glazing frame should be 1000mm. The preferred height of the control line at the upper edge of the window or window frame should be 2000mm. b.
The preferred height of the control line at the upper edge of the door frame should be 2000mm. .c.
When another choice is made for the control line height of the above items, it should be selected according to the integer multiple of the standard module 100mm specified in GB7386.1.
3.2 Horizontal control dimensions
Horizontal control dimensions refer to the width and spacing of the control area including structural compartments, linings, etc., and also refer to the spacing of the middle area of the compartment opening, as shown in Figure 2.
W.GB 7386.287
3.2.1 In order to fully utilize the coordinated elements in terms of dimensions, a box-shaped structure shall be adopted. The inclined and (or) curved front wall, side wall and side plate of the cabin shall be avoided as much as possible, or eliminated on the inside. If there is a bend and (or) tilt, its influence shall be taken into account to obtain the minimum modular coordination.
3.2.2 The underwater dimension of the control area refers to the dimension within the limit of this area, as shown in Figure 13. The width dimension of the control area includes the dimensions of the space required for the components installed therein (such as soft reinforcement materials) and the accessories of the cable, the chain parts, the insulation layer and the village board.
The dimensions of the control area shall be taken as integer multiples of 50mm. 3.2.3 The intermediate area is suitable for arranging non-modular size elements, such as bulkheads. Their size can be determined based on the actual size of the bulkhead plate and its supporting parts, plus the top size of the facing layer and fixings, but the size of the decorations is not taken into account. 3.2.4 The control dimension values for the area spacing should be selected according to Table 1.

Integer multiple of 0 (maximum)
The positioning of components in the coordination space can be done in a directional manner, but the positioning in the vertical and horizontal directions should be distinguished. 4.1 Vertical positioning
The vertical positioning of components only requires a dimension from the component to the surface of the finished floor, as shown in Figure 14. The vertical positioning dimension should be selected according to Article 3.1.
4.2 Horizontal half positioning
The horizontal positioning zone of the component should have two dimensions. For this purpose, grid positioning should be adopted as shown in Figure 15. The horizontal half positioning dimension should be selected according to Article 3.2.
.4.8 Grid
GB7386.2—87
The use of a grid on a drawing provides a practical reference system for determining the size and position of modular components. 4.3.1 Grid size
The basic modular grid, i.e. a grid with a line spacing of 100 mm, is generally used in drawings with a scale of 50 and 1:20, as shown in Figure 16. Figure 16
The 300 mm grid is often used in general layout drawings. On this grid, the component strips are deviated from the grid lines, as shown in Figure 17.
Note: In actual application, in order to keep the drawing clear, grid lines may not be drawn in the dense graphics area if necessary. 14
Generally used for scales of 1:200 and 1:100
W.GB7886.2—87
4,3,2 Application of grid
When applying the grid to the layout of ship accommodation cabins, the relationship between the grid and the area will depend on the size of the grid, the area width, the method of selecting the area spacing, and the intersection of continuous or discontinuous grids. Discontinuous grid: For the convenience of detailed design, it is recommended to use a discontinuous grid to adapt to the changing width of the city. The control line is located on the interface (surface) of the area under the area
, and the area spacing is multiple modules, as shown in Figure 18. This method can ensure that the available space is fully modular. Its advantage is that it can make full use of the coordination elements.
Continuous grid, it is more convenient to use a continuous grid when conducting preliminary design of cabin plans, as shown in Figure 19. b
In this case, the change relationship between the grid writing area is more obvious. Therefore, attention should be paid to ensure the allowable width of the middle area in a specific layout.

4.4 Limits
4.4.1 Limit conditions
The coordination space series specified by the control line should be the preferred series. However, it is sometimes inevitable that the components in the coordination space will exceed or fall short of the main reference plane of the adjacent area. This relationship between the main reference plane that determines the limit of the control area and the base plane that determines the coordination space limit of the optical component or assembly is called the limit condition, as shown in Figure 20.
W.GB7386.2-87
4.4.2rE Negative limit conditions
When the limit of the coordination space exceeds the upper reference plane, its limit condition is positive, as shown in Figure 21. When the limit of the coordination space does not reach the upper reference plane, its limit condition is negative, as shown in Figure 22. Figure 21
4.4.3 Zero limit condition
When the limit of the coordination space coincides with the upper reference plane, its limit condition is zero, as shown in Figure 23. 4.4.4 Insertion depth
When the limit of the coordination space needs to exceed the upper reference plane of the determined area due to functional requirements, the insertion depth can be used to solve Figure 24. The insertion depth value should be selected according to Article 3.1 of GB7386.1 to ensure the modularization of components. Figure 24
WGB7386.2-87
By adding or subtracting the boundary conditions from the preferred coordination space (i.e. the case where the limit condition is zero), there may be a series of coordination spaces under various conditions. However, in order to standardize components, the limit conditions should be limited to zero as much as possible. 4.4.5 Filler
If the final coordination space derived from the preferred series and limit conditions in the grid is non-modular, modular components and "filler" can generally be used to fill the space during the layout and assembly, as shown in Figure 25. The use of "filler" will increase the flexibility of the limited series of modular components, so that it can meet a wider series of coordination spaces.
