Description

The subject of the present invention is essentially a process for

  realization of plans for the installation of industrial units, for example refining units,

distillation or the like.

  More specifically, it relates to a method of producing installation plans, based on a model of

  coenception of an industrial unit to be built.

  It is already known how to make industrial installation plans based on the layout of the various machines, isometric sketches of the piping lines, different diagrams and plans.

detail or the like.

  The layout of these installation plans required a high number of hours of office work and, moreover, did not make it possible to highlight and completely eliminate the errors of implantation of the space of different elements of the office. industrial unit, for example

piping lines.

  Moreover, from these installation plans, a construction model of the above-mentioned industrial unit was constructed. This model was mainly intended for the client and used by the latter either for the initiation of the staff or for the presentation of the installation. - Moreover, it should be noted that this model of realization brought substantially no information for the studies of detail, and generally did not make it possible to make the5 errors possible of imolantation

  that too late to avoid a major breakage.

  -CI Partially to overcome this last drawback, we now realize models of units design

  providing a three-dimensional study plan.

  Thus, this three-dimensional study plan makes it possible to visualize in an explicit manner and to optimize the implantation of equipment, piping and the like, as well as access for operations and maintenance.

of the industrial unit.

  This design model also allows during its development, to study the details and to highlight the non-existent implementation errors.

  revealed by the above-mentioned embodiment.

  It became very interesting from this

  tool, to be able to carry out installation plans

lation of the industrial unit.

  The main purpose of the present invention is to provide a solution to this problem by proposing a method for producing installation plans from a design model, making it possible to obtain such plans, in an operation requesting a number of hours of study desk work very reduced by

  in relation to the hours of work required to

  installation plans in accordance with the

  tional. In addition, these new installation plans allow, instantly, an excellent visualization

  different piping circuits, or the like.

  For this purpose, the subject of the invention is a process for producing plans for the installation of an industrial unit, such as, for example, a refining unit, distillation or the like, characterized in that it consists in constructing all first, a design model of said unit; and subsequently photographing at least a portion of said mock-up to obtain a photoplan resulting from the orthogonal projection of said mock-up portion on a determined projection plane and so as to obtain predetermined and controlled planimetric displacements on the photoplan. Thus, this method makes it possible to produce installation photoplanes having a predetermined and controlled low parallax defect, such that the plane

  obtained respects the different ratings.

  According to one characteristic of the invention, the model

  of aforementioned design is built in super-

  placed and dismountable, constituting as many predetermined predetermined rojection planes. According to another characteristic of the invention, it is vaterialized, advantageously on the aforementioned model,

  projection plans by a flat and transparent element.

  Thus, it is easy to isolate from the whole of the model, 1U the part corresponding to a predetermined projection plane, e to realize the photoplan of this part following the

- Process of the invention.

  According to yet another characteristic of the invention, partial photoplans of the recited unit are produced in order to obtain an installation plan for said unit. This allows, in the case where the design model has significant dimensions, to achieve a

  plan of installation or photo of said unit

  both the standards of planimetric displacements.

  Advantageously, these planimetric displacements corresponding to the parallax defect are smaller than a value fixed in advance which is a function of the number of photos constituting the assembly, and for example lower

about 2 mm.

  The present invention also relates to an installation photoplan of an industrial unit obtained by the

method of the invention.

  In addition, the present invention also relates to a model for implementing the method of the invention, characterized in that it is carried out in one or more transverse planes, for example parallel, in a removable manner, which planes are materialized by transparent elements for example plates of

plex-iglas or the like.

  Other features and advantages of the exhibition appear

  more clearly in the light of the explanatory description

  which will follow, made with reference to the accompanying schematic drawings given solely by way of example and in which: - Figure 1 is a perspective view illustrating an embodiment of a model of anuneunité unit, according to the invention; FIG. 2 is a view illustrating the installation plan or photoplan of the level 1 of the figure 1 obtained by the method of the invention; and FIG. 3 is a diagram showing planimetric displacement due to a reproduction

  To achieve installation plans, using the method of the invention, it is necessary to make a model A of an industrial unit, and to make a photographic reproduction of the model for

  get different plans for installation.

  We will now describe with reference to FIG. 1, the first step of the method according to the invention, in other words the realization of a

  model A - -: 'industrial unit.

  This Macquette A is a small scale representation, usually at 1 / D3 of the industrial unit

  as it will be built.

  This model can be developed as a final product as a result of the detailed studies and from the documents prepared for the construction of the facility. In this case this model is called

realization model.

  On the contrary, con-normment to the invention, the maque-tte (is' aDoree ncrn not a final; cduit final but as a working document, to study the details of in.staation. ee is then said

  Such a model is already carried out in the offices of% tud e and- Pcrmet to the various sections 7-- specialized, for e :: eg electricity (, civil e, engineering

  mechanics, control and regulation or the like, to be able to materialize as and when

  the progress of studies, the options taken.

  Moreover, the development of this model makes it possible to immediately spot implantation errors such as, for example: interference between metal frameworks and pipes, interferences between pipes themselves,

  - access to control devices and valves.

  As a result, it appears that this model can be used for many applications, especially for the capture of isometries, in other words the

  description of the path of the different lines of

pipes.

  According to the invention, another important application

  of this model is the realization of the plans of

photography.

  These installation plans are by definition orthogonal projections, on a reduced scale of horizontal slices or judiciously selected levels of the installation. For this purpose, the model A for the design of an industrial unit, illustrated in FIG. 1 and comprising, by way of example, two columns 1, storage or supply tanks 2 fixed on a support 3, and various pipes 4 assuring the flow of fluids between these different elements, is carried out in particular by the designers of the office

  piping study, in a manner known per se.

  According to the invention, this design model A is divided into horizontal slices of different levels It, 1tY, IV, V. According to the invention, these levels II, III, IV and V are carefully determined and divide an industrial unit. in horizontal slices chosen as indicated above. In other words, the levels or cutting planes of the model correspond to the projection planes on which, according to the conventional method, the plans would be made.

  installation of the industrial unit.

  According to the invention, these cutting planes or levels II, III, IV, V are materialized in n: in planar transparent elements 5 6 * a 6.b 7-a 7-b '8 by means of plates for example of plexiglass. The model part corresponding to a horizontal slice is fixed on

  the plexiglass plate, which serves as a support.

  According to the invention, the model is removable

  to isolate each horizontal slice and -

  to make a photographic reproduction of

this isolated horizontal slice.

  Moreover, it should be noted that the plans for

  projection of a horizontal slice, or level can -

  be constituted by several parallel planes offset vertically with respect to each other, as can be seen in FIG. 1 for the projection plane

  It is made up of plexiglass plates. 6a and 6b.

  In addition, it is advantageous to carry on the model information to facilitate its reading and also to facilitate reading of the installation plan made from it. This information is for example: - labeling of all piping lines - instrument numbering

  - the identification of different dimensions.

  Thus, the design model A shown in FIG. 1 and produced as described recently makes it possible to obtain the various installation plans of the industrial unit by photographic reproduction of the

  different horizontal tranches determined and materialized

on said model.

  The process of photographic reproduction and of realization of the installation plans, according to the invention, will now be described with reference to FIG. 2 and in accordance with the invention, with reference to FIG. 2 and FIG. , we will describe the realization zm, _r ad'ins tu in of the fixed horizontal slice 3_ It I

  optics - h is the height relative to a reference plane

  for which the deformations will be null.

  According to the invention, this planimetric displacement is controlled so as to obtain a displacement

  maximum planimetry less than 2 mm.

  As a result, the photoplanes thus obtained have dimension accuracy criteria that are substantially identical to the installation plans produced by the conventional method. Furthermore, in order to obtain a non-distorted and shaded photograph, it has therefore been necessary to develop and implement a

  optical bench of specific shooting.

  Thus, to avoid any perceptible distortions, it is advantageous to use a reproduction lens with a large focal length. This objective also makes it possible to have a quality of enlargement and reproduction of

clichés obtained excellent.

  In addition, it is advantageous from a technological point of view, to move the part of the model to Dhotographier in a perpendicular vertical plane

  to the horizontal axis of shooting, which is fixed to him.

  So to do this, we use a portB-model or a transparent vertical plate strictly perpendicular to the axis of view, and mobile-in relation to this

  last, in a horizontal or vertical direction.

  It is necessary to avoid any orthogonality defects

  between the axis of view and said platen.

  Thus, the method of the invention makes it possible to obtain quickly and precisely precise installation plans or photoplans and much more exploitable than

the classic drawing.

  By way of example, FIG. 2 illustrates the installation plan or photoplan B obtained by the method of the invention from model A, and representing

  the lower horizontal slice of this model.

  Furthermore, it is also possible by means of the method of the invention, elevational views of an industrial unit, without departing from the scope of the invention. Of course, the invention is not limited to the embodiment described and shown which has been given by way of example. Thus, the cutting of the mock-up in horizontal slices can intervene either during the design of lamnquette or after it, without departing from the scope of the invention. This means that the invention includes all the means constituting technical equivalents

  described means as well as their combinations if these
