Wholesale Q235B long-span light steel structure multi-storey prefabricated steel frame construction
Multilayer steel structure is an advanced building structure form, which has many advantages and characteristics.| item | Parameter range or common specifications | Instructions |
| Column spacing | 6-9 meters | The economic column distance is generally in this range, when more than 9 meters of roof purlin and wall frame system of steel increased more, the comprehensive cost may not be economic; When the load is large, the column spacing should be reduced accordingly |
| span | 6-12 m or so (frame beam span) | The economic span of the multi-storey steel frame is generally 6-8 meters, and when the basement parking space is considered in the office hotel, the column distance (beam span) is generally about 8.4-9 meters |
| Steel beam specification | H-beam, box beam, such as H200×200×8×12, etc | H200×200×8×12 "means that the height of the steel beam is 200 mm, the width is 200 mm, the thickness of the web is 8 mm, and the thickness of the flange is 12 mm, and the specific specifications are selected according to the span and load |
| Steel column specification | H-shaped steel column, box column, such as HW300×300×10×15, etc | Similar to the expression of steel beam specifications, the specific steel column specifications are determined according to the height, load, seismic requirements of the building |
| Floor thickness | 100-150 mm | Common cast-in-place monolithic concrete floor thickness range, precast concrete composite floor, steel skeleton light floor thickness also has the corresponding common specification range |
| Steel material | Q235, Q345, etc | Q235 is an ordinary carbon structural steel, and Q345 is a low-alloy high-strength structural steel, which is selected according to the mechanical requirements of the structure and the use environment |
| Weld grade | Level one, level two, level three | The weld grade is determined according to the importance of the structure and the stress of the weld, and the important connection parts generally require a higher weld grade |
| Antiseptic treatment | Hot dip zinc, spray anticorrosive paint, etc | According to the use environment and design requirements of the steel anti-corrosion treatment, in order to extend the service life of the steel structure |
| Fire rating | Determined according to architectural design requirements | Multi-storey steel structure buildings need to meet certain fire grade requirements, and the fire resistance of steel structure can be improved by spraying fire retardant coatings and wrapping fire retardant materials |
