What is Design Steel Structure Warehouse in China?

Design steel structure warehouse in China according to regulations and standards will be mentioned in this article. At the same time, we also explained a number of standards related to the design of the factory from the foundation to the roof.

What are the Types of the factory floor?

Depending on technology requirements and usage conditions, the factory floor comes into types:

• Cement floor
• Moreover, Reinforced concrete foundation
• Concrete foundation with impact resistant steel chips
• Similarly, Concrete foundation is resistant to acid and alkali corrosion
• Cement tiled floor
• Furthermore, Steel background
• Wood plank flooring, plastic
• In addition, asphalt concrete foundation

The design of the design steel structure warehouse in China at the locations good to use for loading and unloading bulk materials must be flat. The ground surface must have a hard lining to ensure quick drainage.

Factory foundation design standards

The design of the foundation and technical systems of the underground part of the building must be suitable with the physical and mechanical properties of the ground and the characteristics of the natural conditions in the area where the factory is built.

Depending on the hydrogeological characteristics, there are different types of foundations such as single foundation, pile foundation, ice foundation, raft foundation, etc.

Design a protective layer for the nail:

• Nails subjected to high temperatures must have a protective layer of heat-resistant materials.
• Foundations subject to corrosion must have appropriate anti-corrosion measures.

Current standards

• Design standards for pile foundations
• Similarly, Design standards for building foundations and buildings

Design standards for roofs and design steel structure warehouse in China

Design standard slope of factory roof depends on the material selected for roof

• Asbestos-cement roofing sheets: from 30% to 40%
• Moreover, Corrugated iron roof: from 15% to 20%
• Tiled roof: from 50% to 60%
• Roofing with reinforced concrete panels: from 5% to 8%. For this type of roof, when designing, it is necessary to create a heat gap in the waterproof reinforced concrete layer, the distance between the heat joints should be greater than 24m along the house.

Design standards for rainwater supply and drainage in steel structure works

• For multi-span design steel structure warehouse in Chinaroofs, depending on the roofing material. It is allowed to design internal or external drainage and connect to the common drainage system.
• If internal drainage is designed, a suspension system must be good to use or a water pipe must be good to use to drain water into the ditch in the workshop. Drainage ditches must have reinforced concrete covers, which can be easily removed.
• For single-span factory roofs, rainwater can flow down freely when the width is less than 24m, the height of the columns is less than 4.8m. In addition, when the column height is from 5.4m or more, it is mandatory to have a system of troughs leading to the ground.

If the height difference between the roof door and the leveling roof of design steel structure warehouse in China is greater than or equal to 2.4m. There must be a catcher and an outlet pipe. On the contrary, if it is less than 2.4m, water can flow freely, but measures should be taken to strengthen the roof below within the area of ​​the storm water.

The roof door must be fitted with fixed glass

The roof door must be fitted with fixed glass (the thickness of the glass must not be less than 3mm). The lower part is left open; the upper part has a racing roof. From latitude 18 degrees North and below, the glass part of the roof must be designed to prevent direct sunlight. There are also some special cases:

• In case of not making roof doors: one- or two-span workshops with natural lighting through the design steel structure warehouse in Chinastill meet the requirements and do not have heat, moisture or toxic devices.
• In the case of ventilation roof doors: the factory generates a lot of heat, moisture or toxins
• Moreover, in case the roof door is not glazed: the factory only requires ventilation and a roof to prevent rain, then there is no need to install glazing but only leave a gap (the height of the space is taken from 0.15 m to 0.3 m). m).

Above is the standard design of steel structure in the drainage slope.

Design standards for design steel structure warehouse in China

Depending on the type of factory, businesses will choose one of the following types of walls to build: load-bearing walls, self-loading walls and frame insert walls.

Design standards for skirting boards need to ensure:

• The base of the brick wall must have a rain-proof layer of bitumen or other material.
• The moisture-proof layer at the foot of the wall must be made of cement mortar grade 75, 20cm thick and placed horizontally at the height of the finished substrate.

Partitions can be made from materials such as reinforced concrete panels, concrete steel mesh, steel mesh with wooden or steel frames, plywood panels or plywood.

Design steel structure warehouse in China have span size less than or equal to 12m and the height of columns will be less than or equal to 6m.

Design standards for doors and windows

One of the design standards for steel structures in doors and windows that we need to follow.

Technical standards for doors:

• The door must open to the outside.
• Manufacturer’s doors: designed with a size larger than the size of trucks, at least 20cm in height and 50cm in width.

Specifications for windows:

• The height is less than or equal to 2.4m from the floor or higher.
• In case the window is over 2.4m high, it should be fixed to the frame and clamped to hold the door firmly.
• Moreover, a standard factory window should be designed with a mechanical opening and closing system.

Note: Factory design standards for doors and windows must ensure ventilation and optimize natural light sources. In addition, design steel structure warehouse in China must also ensure to meet the requirements of fire prevention and fighting.

Steel structure design standards

In recent years, there have been a series of foreign-invested projects in our country. Among those works, there are works that apply design steel structure warehouse in China standards of countries around the world. Such as European standards, USA (American Concrete Institute Code AISC), UK (British Standard BS)
