Abstract
The utility model patent discloses the combined I-shaped steel of pin-connected panel cold bending thin wall, it is characterized in that: combined I-shaped steel cross section is formed by the Combined concrete of cold bending thin wall i iron and its inside, has twice stiffening rib in the i iron web after combination; Cold bending thin wall combined I-shaped steel web place is provided with twice stiffening rib, effectively can improve the cripling phenomenon of web place steel plate, improves the supporting capacity in cross section; Due to the existence of combined I-shaped steel edge of a wing place stiffening rib, light gauge cold-formed steel shape and inner constructional materials of filling are retrained mutually, improves the supporting capacity in cross section further; Employing forming mill processes, and work flow is easy, and simultaneously have can as the template of building for light gauge cold-formed steel shape crust, shortens process time and product quality is easy to control.This combined I-shaped steel can be widely used in pressurized in construction work and flexural member.
Description
Technical field:
Patent of the present invention relates to a kind of shaped steel, the combined I-shaped steel of cold bending thin wall used in especially a kind of building structure.
Background technology:
Quality is light, intensity is high, process the advantages such as easy because it has for light gauge cold-formed steel shape, obtains in recent years and use widely in building structure.Traditional i iron cross section is back-to-back assembled by two C-type steel.When the bearing capacity of light gauge cold-formed steel shape component increases, but due to the restriction of architectural design, when can not change cross sectional appearance size, bearing capacity can only be increased by the mode increasing steel plate thickness.Meanwhile, traditional light gauge cold-formed steel shape buckling problem is comparatively outstanding, becomes the principal element considered in bearing capacity and stability Design process.
Therefore, propose a kind ofly can delay light gauge cold-formed steel shape flexing and the combined member improving its bearing capacity seems necessary.
Summary of the invention:
The object of the utility model patent is to provide the combined I-shaped steel of pin-connected panel cold bending thin wall, for improving the buckling problem of traditional cold bending thin wall i iron, can improve the bearing capacity in cross section, and have good stress performance and economy.
Splice after the utility model Patent design employing forming mill machined steel sheet metal forming, Hollow H-shaped steel is connected to form by welding or bolt, again to the combined I-shaped steel beam column of hollow interior joints cement mortar or light weight aggregate concrete, it is characterized in that: Hollow H-shaped steel cross section is assembled by the T-shaped cold bending thin wall cross section of two identical band stiffening ribs, the i iron edge of a wing after assembled and web are hollow, and have twice stiffening rib in web.
Patent of the present invention is compared with existing i iron cross section, and advantage is:
1. i iron section form is steel-cement mortar or Steel-Concrete Composite Sections, and due to the existence of cement mortar or light weight aggregate concrete, the supporting capacity in cross section is improved;
2. cold bending thin wall i iron web place is provided with twice stiffening rib, effectively can improve the cripling phenomenon of web place steel plate, improves the supporting capacity in cross section;
3., due to the existence of combined I-shaped steel edge of a wing place stiffening rib, light gauge cold-formed steel shape and inner constructional materials of filling are retrained mutually, improves the supporting capacity in cross section further;
4. adopt forming mill to process, work flow is easy, and simultaneously light gauge cold-formed steel shape crust has the template can built as cement mortar or light weight aggregate concrete, shortens process time and product quality is easy to control.
Accompanying drawing illustrates:
Fig. 1 ~ Fig. 4 is the combined I-shaped steel schematic cross-section of pin-connected panel cold bending thin wall, and wherein Fig. 1 and Fig. 2 adopts the connected mode of welding; Fig. 3 and Fig. 4 adopts the connected mode of high-strength bolt.Label in Fig. 1, Fig. 2: 1 weld seam, 3 when be weld seam, 2 on T-shaped cross section being assembled is hollow flange, 4 be hollow web, 5 be web stiffening rib, 6 be wing plate stiffening rib.Label in Fig. 3, Fig. 4: 1 bolt, 3 when be bolt, 2 on T-shaped cross section being assembled is hollow flange, 4 be hollow web, 5 be web stiffening rib, 6 be wing plate stiffening rib.
Detailed description of the invention:
As depicted in figs. 1 and 2, the thickness of steel product forming the combined I-shaped steel cross section of pin-connected panel cold bending thin wall is 2mm ~ 6mm, is processed into similar T-shaped cross section through forming mill; The mode that the T-shaped cross section processed two subsequently carries out adopting welding (Fig. 1) or bolt to connect (Fig. 2) respectively connects, and the edge of a wing forms stiffening rib, web forms stiffening rib; Then, undertaken assembled by two T-shaped cross sections, the mode adopting welding (Fig. 1) or bolt to connect (Fig. 2) equally connects, and the edge of a wing of formation and web are hollow, and web place is with twice stiffening rib.Finally, at hollow position joints cement mortar or light weight aggregate concrete.
The height in the combined I-shaped steel cross section of cold bending thin wall is 90 ~ 350mm, and width is 60 ~ 150mm, and edge of a wing height is 10 ~ 25mm, and edge of a wing stiffening rib is of a size of (10 ~ 15) mm × (10 ~ 15) mm.
