Definitions

  • the invention relates to the field of light steel construction, in particular to a three-dimensional light steel frame composed of a bidirectional continuous double beam for light steel construction.
  • Light steel buildings using light steel roof trusses have entered a period of rapid development in China and have been widely used in industrial buildings.
  • Light steel houses have become a new field and a new growth point for light steel structure applications.
  • the cost of light steel construction is generally higher than that of traditional concrete structures, but it has competitive advantages such as fast construction, energy saving and emission reduction.
  • More and more construction units have recognized the superiority of light steel structures and have gradually become the preferred structural form for industrial buildings, and have also been widely used in low-rise civil buildings.
  • Light steel construction using light steel roof trusses has significant improvements in terms of architectural design, structural design, and fabrication and installation techniques.
  • Currently used light steel roof truss structural beams, structural columns, etc. are generally connected by means of docking (such as fixed or hinged). Since a large number of structural beams, structural columns, and the like are used in the light steel roof truss of the present structure, the jointing method causes a complicated joining process and at the same time, a serious error accumulation occurs.
  • the patent still has the following deficiencies: the patent does not refer to the slab, roof, reinforced lightweight composite slab, anti-lateral force pull rod and other components, and cannot form a complete three-dimensional light steel structure, the continuous double beam is not clear The relationship to the continuous double beam, the three-dimensional frame assembly is difficult, and the individual components and the overall frame structure are insufficient.
  • the continuous double beam in this patent cannot meet the requirements of different sections in response to different stress conditions, resulting in waste of material use.
  • the continuous double beam cannot be used with different single beam combinations due to different needs.
  • the roof frame and roof truss are not flexible. The connection between the two ends is continuous double-beam overlapping, and the continuous double-beam connecting member is too long to cause difficulty in assembling the frame.
  • the two-way continuous double-beam overlapping combination causes waste of space and causes uneven stress on the column and beam joints.
  • the embedded bolt fixing connector is only fixed at one point of the bottom of the integrated positioning steel frame member, can not maintain vertical, and is easily loosened during construction. At the same time, the embedded bolt must be assembled and locked after the foundation concrete reaches a certain strength. Steel frame.
  • Square steel parts commonly used in the field of light steel construction are generally square steel tubes or butt welded with two C-shaped steels.
  • the bolt holes of the closed square steel pipe connected with other components can only be processed by drilling or flame cutting, and cannot be punched by punching, which leads to high processing cost; the closed square steel pipe cannot be joined with other components by using the locking high-tension bolt. Thereby greatly reducing the bearing capacity of the joint.
  • galvanization is generally performed after the processing of the square steel pipe is completed, which results in high production cost. For example, C-beam butt welding with two galvanized steel sheets is formed by rolling, and this processing method will destroy the rust-proof layer of the galvanized steel sheet.
