How to stipulate the size of a single storey plant? What are the design points of a single storey pl

The size of the single-storey plant is specified as follows:

The rack structure of the single-storey plant is the basic structural form of the single-storey plant at present. Its span can exceed 30m, the height can reach 20 30m or more, and the crane tonnage can reach more than 150 tons. Gantry rigid frame is generally suitable for metalworking, machine repair, assembly and other workshops or warehouses with a crane lifting capacity of no more than 10 tons and a span of no more than 16-34m.

Rack structure: As the name suggests, one row at a time. It is mainly used for single-storey workshops, which are composed of roof trusses, columns and foundations to form a transverse plane rack, which is the main load-bearing system of the plant, and then connect the plane racks through longitudinal components such as roof panels, crane beams, and supports to form an overall spatial structure.

The row frame is composed of roof trusses (or roof beams), columns and foundations, and the columns are hinged with the roof truss and just connected to the foundation. It is the basic structural form of single-storey plant structure.

The standard height of an industrial plant is usually 5m-6m. If it is a single-storey steel structure workshop, it must be more than 6m.

Industrial plants can be divided into three types, General production plants: production plants in normal environments. ** and fire hazard production plants:

Factories that normally produce or store ** and fire hazards. Production plants in harsh environments: dusty, humid, high temperatures, or production plants with steam, vibration, smoke, and radioactive substances.

The difference between a standard workshop and a non-standard workshop:

1. Standard workshop:

A standard industrial plant is a property that is widely used for production industrial purposes.

2. Advantages of standard industrial plants

The standard industrial plant has good compatibility, suitable for the development of liquid synthetic sheets, and the property forms are mainly single-layer, multi-layer, townhouse and superimposed.

Companies can quickly get into production and reduce the time it takes to build a new plant.

Long-term leasing of factory buildings is actually a kind of financing behavior, which can save the initial investment, bring several times the capital of the enterprise, and facilitate the expansion of the enterprise.

3. Non-standard customized workshop:

Non-standard custom-built factories are tailor-made industrial properties for users, and after completion, they are generally leased to users for 5 to 10 years. This kind of product form is still in the stage of exploration and practice in China, mainly to meet the specific requirements of customers, and the service objects are mostly multinational companies.

4. Advantages of customizing and renting out the plant:

The developer provides a one-stop service to reduce the tedious procedures involved in building a factory, and the user does not need to set up a dedicated infrastructure team for a project.

Developers are actually providing a financial means to reduce the one-time investment of users.

It is beneficial for users to lock in business risks, reduce the risk of holding properties, and reduce short-term rental risks.

Provide opportunities for users to exit the industry and reduce the burden on users' assets. <>

In the single-storey plant, the production line is generally arranged in the horizontal direction. This kind of plant structure is simple, and can adopt large span and large depth; It is convenient to use heavy lifting and transportation equipment, and heavy equipment can be installed on the ground; You can use skylights for lighting and ventilation. The single-storey plant is highly adaptable, which can be used to produce both heavy and light products; It can be built with a large span and a large area, as well as a small span and a small area.

However, the large footprint increases the length of outdoor roads, pipelines and transportation lines.

It can be a single-span or multi-span (double-span) plane, and each span is arranged in parallel, and there can also be vertical spans. The plant is mostly rectangular, and some hot processing workshops often adopt shape, shape. The living room and auxiliary room are mostly arranged along the edge of the column or the dead corner of the crane, and can also be built near the plant or around the plant, but not too much, so as not to hinder the lighting and ventilation of the plant.

The column spacing of the single-storey plant is more than 6 meters, and sometimes the use of meters, etc., and the span is also used to 3 meters as the basic parameter, so as to facilitate the finalization of the components. The height of each span of the multi-span plant is different, and it should be appropriately adjusted to simplify the processing of components and structures, and improve the lighting and ventilation effect.

The single-storey plant structure usually uses a reinforced concrete frame system, and the steel structure system can be used for special tall or vibrating plants. When heavy cranes or large suspended transportation equipment are not required, large spatial structures such as thin shells, grids, and suspension cables (see Suspended Structure Construction) can also be used to expand the column network and increase flexibility.

The common structural forms of single-storey workshops include row frame structure and rigid frame structure.

1. Row frame structure.

A row frame structure consists of roof trusses or roof beams, columns, and foundations. Normally, the row frame columns are hinged with the roof truss or roof beams, and are rigidly knotted with the underlying foundation. According to the different production process and use requirements of the plant, the rack structure can be designed as a single span or multiple spans, contour or unequal height.

2. Rigid frame structure.

Rigid frame structures usually consist of reinforced concrete beams, columns, and foundations. The rigid frame column and the beam are just connected, and the foundation is often hinged to check the hidden dan. According to the different forms of beams, the rigid frame structure is divided into a polygonal portal rigid frame and an arched portal rigid frame.

The advantages of the rigid frame structure are the integral combination of beams and columns, the types of components are few, the production is simple, and the material is saved compared with the reinforced concrete row frame structure when the span and height are small. However, its disadvantage is that the turning point of the beam and column is easy to produce cracks due to the large bending moment; At the same time, under the action of the pure force of the beam, the rigid frame column will produce a relative displacement, which will change the span of the plant.
