Square tube is widely used in the construction field, mainly including the following aspects:
1. structural support
Building frame: in some multi-storey or high-rise buildings, square tubes can be used to build the main frame of the building. It has high strength and stability, and can bear the self weight of buildings, wind load, seismic load and other external forces. Compared with the traditional round pipe, the square pipe has clear edges and corners, which is convenient for connection and installation, and can make the building structure more regular.
Roof support: for some large-span roof structures, such as gymnasiums and exhibition halls, square tubes are often used to make truss or grid structures to provide strong support and ensure the stability and safety of the roof. The structure composed of square tubes can be flexibly arranged according to the shape of the roof and the design requirements to achieve a variety of unique architectural shapes.
2. door and window frames
Door and window frame: square tube has good rigidity and straightness, which is an ideal material for making door and window frames. It can be processed into door and window frames of various sizes and shapes by cutting, welding and other processes to meet different architectural styles and use requirements. Square tube door and window frames are not only beautiful and generous, but also have good sealing and sound insulation performance, which can effectively improve the thermal insulation effect of buildings.
Curtain wall structure: in the curtain wall design of some large commercial buildings and high-rise buildings, square tubes are also widely used in the keel structure of curtain walls. The square tube keel can provide reliable support for the curtain wall panel, and its simple appearance can be matched with glass, stone and other curtain wall panels to create a modern and simple architectural appearance.
3. decoration
Partition: square tube can be used to make indoor partition and divide the space reasonably. Through different arrangements and combinations, various styles of partitions can be designed, such as simple modern style, Chinese style, etc. The square tube partition not only has certain permeability, but also can play the role of separating the space, increasing the sense of hierarchy and interest of the space.
Decorative lines: in the indoor and outdoor decoration of buildings, square tubes are often used as decorative lines to outline the outline of doors and windows, wall corners, ceilings and other parts. It can enhance the architectural sense of line and three-dimensional, and make the architectural appearance more exquisite and beautiful. In addition, the square tube can also have different colors and luster through surface treatment, such as spraying, electroplating, etc., to meet different decorative needs.
4. ventilation and water supply and drainage
Ventilation duct: in the ventilation system of buildings, square pipes are often used as ventilation ducts. It has a large ventilation cross-sectional area, which can effectively transport air and meet the ventilation requirements in buildings. The square pipe ventilation duct is easy to install, which can be flexibly arranged according to the layout of the building space, and can reduce heat loss and noise transmission through thermal insulation treatment.
Water supply and drainage pipes: square pipes are also used in water supply and drainage systems of some buildings. Especially in places with high space requirements, such as toilets, kitchens, etc., square pipes can be used as drainage pipes, and their square shape can better fit the corner or other building structures, saving space. At the same time, the square pipe has good corrosion resistance, which can ensure the normal operation of the water supply and drainage system.
