DE19802654A1 - Modular octagonal industrial unit as prefabricated unit with central supply systems and completed by optional extensions on one or more sides - Google Patents

Abstract

The octagonal unit can be completed by further modules set in planes one above the other and supported by supports (3). One or more modules can be added onto one or more sides of the octagonal unit. The modules are made from steel, steel concrete or prefabricated concrete parts. The unit can be serviced by central supply systems

Description

Subject of the invention

The invention relates to a new concept for industrial plants, which are designed from modules in octagon shape.

This construction concept enables industrial plants to be erected according to productivity or process requirements, from one or consist of several modules.

These possibilities bring great opportunities especially for chemical industrial plants Benefits.

The size (outside∅) of the octagonal modules is approx. 24 m. This order of magnitude results from past experience conventional industrial plants considering quantity, size and Equipment type.

State of the art

There are already different types of construction in industrial plant construction known.

The most implemented plant projects are grouped into the so-called refinery construction in an elongated rectangular shape alongside a supply unit (pipe bridge, pipe route) or the so-called factory construction in rectangular or square shape.  

That is for the construction of these conventional industrial plants Presence of optimal, that is straightforward and large-area base areas necessary.

On the other hand, the various trades such as construction, Steel construction, equipment, pipes, fittings, etc. in a complex manner Assembled part by part.

The increase in price and shortage of ideal building areas and the constraint to minimize costs due to the fierce competition in the Plant construction business makes it impossible to stick to the previous concepts to hold on.

Overview of the advantages of the invention

The aim of the invention is to offer technical and economic advantages to achieve the previously known designs.

Due to the modular design, considerably less floor space is required ( Fig. 8, 9), which means cost savings in property costs.

The modular design results in a more cost-effective construction (30-40%). On the one hand by less floor space, on the other hand by the one-off engineering activities as well as through series effects when producing several modules.

Due to the compact circular design, the Area of technical equipment due to shorter distances between the respective apparatus in piping, electrical, measuring technology, insulation and Painting area cost savings (15-20%).  

The modular design offers excellent opportunities for using asymmetrical terrain specifications. Specifically, this means realizing customer requests with regard to vacant lots in the existing factory premises or avoiding obstacles that cannot be removed ( Fig. 9, 11).

An industrial plant in modular design can be extended on almost every side of the module. If an industrial plant is already designed according to process stages in several modules ( Fig. 8, 9, 11), an extension of individual process stages can be implemented without problems.

Depending on requirements, industrial plants can be designed in modular construction in open-air or closed construction ( Fig. 1, 2, 3).

This modular design is equally cheap in steel construction, reinforced concrete or to be realized in prefabricated concrete.

Industrial plants in modular design enable faster and cheaper Assembly, since the modules are already in place before the base plate and Foundations can be made separately and then as Complete structure can be assembled.

This faster assembly progress saves construction costs and enables an earlier start of production.  

The modular form gives the plant operator advantages for maintenance and Repairs, since the shortest paths (for Cranes, scaffolding etc.) to the respective machine or Apparatus components result.

Description of the invention

Module 1 is the basis for the design of an industrial plant in modular design.

The determination of the size of module 1 results on the one hand from the available space, but essentially from the type and size of the industrial plant to be planned. It is therefore advisable to take the process steps of an industrial plant into account when considering the number of modules 1 in order to be able to carry out subsequent extensions or replacement of equipment without problems.

The module 1 , which is shown relatively schematically in FIGS. 1, 2, 8, 9, 10, 11, is clarified in more detail in FIGS. 4, 5 in order to better illustrate the construction. Due to the size of a module 1 with an outer diameter of approximately 24 m in octagon shape and the constructive design of such a construction, there are inevitably eight steel construction elements in a trapezoidal shape.

In order to convey a clearer picture, module 1 with its construction elements was shown in Fig. 4.

Module 1 is shown as a complete unit in FIG. 5.

The module is usually supported by supports 3 (steel or ready-mixed concrete). If a further level is required, the supports 3 are dimensioned accordingly, extended or placed on the module 1 .

The structural arrangement of the apparatus or other equipment on the module 1 is shown in detail III in FIG. 7.

Fig. 1, 2, 3, 8, 9 show the designed in modular construction industry systems 18 and 20. The essential thing here is that these designs are based on industrial systems 19 and 21 which have already been constructed and designed in a conventional manner.

With reference to Fig. 8, 9 can be seen, as is with respect to the compact design and considerably lower space requirements, the modular design advantage.

In the industrial system 20 designed in FIG. 9, the modules of a U-shaped arrangement were created.

According to the method steps, five modules 1 result as an industrial plant unit and one module 1 as a head building 17 . Because of the size of the industrial plant 20 , the head building 17 was designed as a full module 1 in order to enable the increased need for rooms for staff, laboratory, measuring and control center, switch rooms and storage areas. In this version, this industrial plant, built in modular construction, fulfills all requirements such as: B. shortest routes to the energy supplier (pipe bridge 18 ), compact design, less floor space, good expansion options on many sides, good disassembly and assembly options, etc.

8, 9, 10, 11 show a small overview of many planning options .

These opportunities are especially beneficial when new Production sites in vacant lots of existing factory premises or in asymmetrical construction areas are to be integrated.  

Useful side effects of module 1 result from opening 13 , which can be used in a variety of ways.

The head building 17 is expediently designed in a reinforced concrete construction and can be provided with the building cladding 12 in accordance with the climatic conditions.
