Problems solved by technology

The method of cutting the single-girder web of the upper and lower H-bars into double-sided arches, welding the wing plates to make the H-bars, and marking and drilling holes on the superimposed surfaces respectively, because the single-beams of the H-bars welded by the plates are respectively arched , coupled with the unequal thickness and unequal width of the upper and lower flanges, the inevitable thermal deformation during the welding process, it is difficult to effectively ensure the flatness of the superimposed surface of the upper and lo...

Embodiment Construction

[0014] Embodiment: Referring to Figures 3, 4, and 5, each steel plate is cut according to the design requirements, wherein the web 1 of the upper beam H member is cut to form a straight side 1.3, and the other side is cut to be convex and set an arched side 1.1, and the lower beam H One side of the rod web 2 is cut to form a straight side 2.3, and the other side is cut into a concave shape to set an arched side 2.2, and the upper and lower sides of the two webs are respectively welded on the upper and lower sides of the two webs (welding small wing plates on the two superimposed surfaces) 3.1 and 3.2 , to get two H-shaped single girders with one side arched and one side straight. Then mark and drill holes on the straight small wing plate 3.2 of the upper H beam, and finally preassemble the upper and lower H-shaped single beams according to the plane (small wing plate), and use the hole of the upper beam as the drilling hole , with drilled lower beam winglet plate 3.2 connectin...

Abstract

The present invention relates to manufacture process of large span superposed beam of spliced plates. The present invention features that H-shaped monospars are first made through cutting one H-shaped web as the upper spar, cutting one other H-shaped web as the lower spar into the shape fitting to the upper spar, and welding wing plates to two webs to form two, one upper and one lower, H-shaped monospars, and then superposed and connected through fitting drilled holes. The present invention has high in-situ assembling efficiency and high product quality.

Description

technical field [0001] The invention relates to a method for preparing a large-span composite laminated girder assembled with panels, in particular to a method for preparing a composite laminated beam with large-span panels assembled with high flatness and 100% perforation. Background technique [0002] Composite stacked beams assembled with large-span load-bearing plates for steel structures (Figure 1), such as stacked beams for the roof of a large-capacity boiler frame, due to a large load such as 5000T, the span is as large as 30-45 meters, and the beam height is 5500mm~ according to the load-bearing design requirements About 8000mm, due to the limitation of transportation height, it is usually designed as two upper and lower H-shaped bar beams A, and then assembled on site, and the upper and lower H-bars and a wing plate are fixed and combined by bolts. In order to improve the bearing capacity of the stacked beams, the upper and lower H-shaped members are designed and ma...
