The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to the tabula connecting structure of the Wavelike steel webplate compound beam that the utility model proposes, the vertical steel plate of H profile steel is Wavelike steel webplate, be fixed with plain plate in the relative inner position of described Wavelike steel webplate, between adjacent Wavelike steel webplate, be provided with transverse connection structure.
Further, the tabula connecting structure of aforesaid Wavelike steel webplate compound beam, described transverse connection structure includes two ends and arranges the screw thread rod iron of screw thread, major thread sleeve and minor thread sleeve respectively,
Described screw thread rod iron is symmetrical arranged between adjacent Wavelike steel webplate, is connected between two screw thread rod irons by major thread sleeve, and the screw thread rod iron other end is interspersed to be arranged on Wavelike steel webplate, and is fixed by minor thread sleeve.
Further, the tabula connecting structure of aforesaid Wavelike steel webplate compound beam, described Wavelike steel webplate is connected by studs with between plain plate, is respectively arranged with hex nut fixes at the two ends of described studs.
Further, the tabula connecting structure of aforesaid Wavelike steel webplate compound beam, the length of described major thread sleeve is the twice of minor thread length sleeve.
By technique scheme, the tabula connecting structure of Wavelike steel webplate compound beam of the present utility model at least has following advantages:
The utility model is compared with the tabula connecting structure of conventional composite beam, and Wavelike steel webplate can improve shear buckling intensity greatly, reduces the sensitiveness to geometrical defect, and more traditional web shear resistance can increase substantially; Wavelike steel webplate does not bear moment of flexure, there is not the web destabilization problems caused because of bending normal stresses, without the need to configuring longitudinal stiffener; And its shearing resistance buckling strength is comparatively large, only need less steel plate thickness to meet the demands, consideration corrugated sheet steel replaces flat web, and when bending rigidity is close, steel using amount can save about 30%.The combination of plain plate and Wavelike steel webplate further increases the lateral stiffness of web; Screw thread rod iron strengthens the horizontal restrain of compound beam, and the side direction non-deformability of compound beam and overall anti-torsion ability are significantly improved; Compare traditional angle steel to be welded to connect, adopt and to be threaded fixing rod iron, there is the advantages such as simple to operate, quick construction, mounting or dismounting are convenient.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
