The length and width of the portal steel structure building

Generally speaking, when laying the portal steel structure building, it should follow the principle of “length greater than the width”, which can reduce the amount of steel for the portal frame. At the same time can also reduce the wind load between the column support, thereby reducing the steel of the support system. For example, the size of the portal frame building is 60x50m, when the plant is arranged, 60m should be used as the length direction and 50m as the span direction.

Determine the reasonable span for the portal steel structure building

We will determine economic and reasonable spans based on the height of the house, and satisfying production technology and use functions. In general, when the height and the load are certain, if the span is increased, the amount of steel for the portal frame will not increase significantly. But it saves space, reduces the basic cost, and makes the comprehensive benefits more considerable. It is found by a large number of calculations that when the span exceeds 48m, it is suitable for using multiple spans. Its steel volume saves more than 40% compared to a single-span portal frame. Therefore, when designing the portal steel structure building, a more economical span should be selected according to specific requirements. K-HOME will provide more options for you.

column distance selection For portal steel structure building

The technology economy compares that the most economical portal steel structure building column spacing under standard load is 8-9m. When it exceeds 9m, the amount of steel in the roof bars and the wall frame system increases too much, and the comprehensive cost is not economical. The standard load here refers to: the roof is 0.3kn/㎡, and the basic wind pressure is 0.5kn/㎡. When the load is greater, the economic column distance should be reduced accordingly. For factories with more than 10 tons, the economic column distance should be 6-7m. K-HOME will perform scientific calculations based on the location of your project to ensure the security and firmness of the portal steel structure building.

portal steel structure building Roof Options

The roofs of prefabricated houses can be designed and manufactured with various construction materials and technologies. Here are some common types of prefabricated house roofs:

1) Color steel Roofing Sheet & FRP sheet

Color steel sheets, also known as colorful pressure tiles are color-coated steel plates, and they are bent coldly into various wave types. This material is light and durable, difficult to ignite, and anti-corrosion, while easy to install and maintain. Color steel sheets are widely used and are suitable for various types of buildings. It is mainly used in industrial factories, commercial buildings, civil housing, agricultural greenhouses, parking lots, stadiums, exhibition halls, and other construction fields.

FRP sheets are usually used for the top or walls of the building. They have high transparency and anti-ultraviolet ability and can provide sufficient natural light without using electric lights to save energy and environmental protection.

In architectural design, color steel sheet Roof and FRP sheet can be supplemented and cooperate with each other. For example, in the roof structure of the factory building, the FRP sheet can be used to cover the parts that can be permeated, such as channels, machines, or lanes to meet light transmission requirements and performance needs. At the same time, colored steel sheets can be used to cover other parts, such as walls and main roofs, and also play a role in heat insulation. This structural design not only meets the brightness and energy conservation needs of the building but also ensures the strength and stability of the building.

In short, the specific use of color steel sheet Roof and FRP sheet in architectural design can be adjusted and selected according to factors such as building use, climate environment, the characteristics of building materials, and building design needs.

2) ceiling + Sandwich Roof Panel

Sandwich roof panels are a type of roofing system that consists of two metal sheets that are bonded to a core material. The core material is usually made of insulation material such as polyurethane foam or rock wool. Sandwich roof panels have numerous benefits, including high thermal insulation, excellent fire resistance, and ease of installation.

1) Color Steel Sheet

The simplest wall treatment. Because there is no insulation layer, it is not suitable to use as a living place. It is common in garages, agricultural sheds, simple warehouses, factories, and other industries or agricultural buildings.

2) Sandwich wall Panel

The use of the core plate as the wall material has the following advantages:

Inquiring about thermal insulation performance: The insulation and thermal insulation performance of the sandwich board are very superior. The insulation material filled in the middle can effectively isolate the indoor temperature difference, greatly reducing the coefficient of heat transfer, and improving the energy-saving effect of the building.

Construction is convenient and fast: the transportation and installation of the sandwich board are easier and easy to move, which can greatly shorten the construction period.

Environmental protection and energy saving: The insulation materials and substrates used by the sandwiches are mostly environmentally friendly materials. A large amount of garbage will be generated during the construction process to reduce environmental pollution. At the same time, due to the good thermal insulation effect during use, it greatly reduces energy consumption and achieves realization. Energy saving and environmental protection.

Lightweight and high strength: The thickness of the sandwich plate is thinner, and the weight is lighter than the traditional wall material, but the intensity is very high, which can meet the building’s requirements for the wall material.

Good decorative effect: The surface materials of the sandwich board can be treated according to personal preference, such as stuck stone materials, tiles, paint coatings, and other decorative methods, bringing good decorative effects.

Frequently asked questions

Modular prefabricated houses have numerous advantages, including:

Speed of construction: Modular homes are constructed much faster than traditional homes because they are built in a factory setting where all aspects of the process are controlled.

Cost savings: Modular homes are generally less expensive than traditional homes because there is less waste, and they can be built more efficiently. Additionally, the cost of labor and materials can be reduced, as workers are not required to travel to and from the construction site.

Quality control: Because modular homes are built in a factory, quality control is much easier to manage. Prefabrication allows for standardization and consistency, which ensures that all materials and components are of high quality and meet strict building codes.

Energy efficiency: Modular homes are often designed to be energy-efficient, which can save homeowners money on utility bills. They often feature insulation that exceeds code requirements and energy-efficient windows and doors.

Customizability: Modular homes can be designed and built to fit a homeowner’s exact specifications. Modular construction allows for customization in size, layout, and finishes, allowing homeowners to create their dream homes.

Overall, modular prefabricated houses offer many advantages that make them an appealing option for those looking to build a new home.

Modular prefabricated houses have a lifespan that can be similar to traditionally-built homes. The materials used to construct modular homes are of high quality and designed to last, and the building process is highly controlled and precise.

Many modular homes come with warranties that cover the structure, materials, and workmanship for several years, ensuring that any issues that arise are taken care of.

The lifespan of a modular home also depends on how well it is maintained. Proper maintenance includes regular cleaning, inspections, and repairs when necessary. Following a regular maintenance routine can extend the life of a modular home and help it last for many decades.

In general, life depends on multiple factors, including the structure and the encirclement. In addition, it is also closely related to the construction design, construction process, use environment, maintenance, and other aspects. A well-maintained modular home can last upwards of 50-60 years, and some have been known to last even longer.
