Multilayer crossing waveforms steel plate composite component and welding detection method thereof
Technical field
The present invention relates to a kind of composite construction and detection method of steel plate, particularly relate to multilayer crossing waveforms steel plate composite component and welding detection method thereof.
Background technology
Along with the development of Bridges in Our Country structure, new bridge construction form continues to bring out, and is first proposed by France and the world's seat of honour Wavelike steel webplate bridge built, this structure is introduced to Japan, develop, and optimize further, China also introduces this bridge type in eighties of last century.But common corrugated sheet generally adopts single layer structure, and form is more single.And by multi-layer corrugated plate each other veneer compound be a difficult problem always, effectively do not solved.
Summary of the invention
The present invention is cannot veneer compound etc. is not enough and proposes mutually for what solve that existing corrugated sheet has, aim to provide have can veneer compound multilayer crossing waveforms steel plate composite component and weld detection method.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Multilayer crossing waveforms steel plate composite component, comprise longitudinal corrugated sheet, horizontal corrugated sheet, peg, longitudinal corrugated sheet and horizontal corrugated sheet arranged in a crossed manner, the crest of the trough of longitudinal corrugated sheet or crest and horizontal corrugated sheet or trough is crossing contacts, corrugated sheet has hole, and the diameter of perforate is more than or equal to the bar footpath of peg.Corrugated sheet is intersected and places, and connect with welding of peg and be integrated, rigidity and the performance of integrated member can be improved, and corrugated sheet cost is lower, so reduce the cost of combined member.
As preferably, the clear length of peg is more than or equal to the thickness of perforate corrugated sheet.Corrugated sheet can pass in peg bar portion.
As preferably, peg is welded with the corrugated sheet peg machine of other direction by perforate.Longitudinal corrugated sheet and horizontal corrugated sheet improve welding of peg and are integrated, and integrally-built rigidity is guaranteed.
As preferably, the head of a nail of peg is positioned at the outside of perforate corrugated sheet, and contacts with perforate corrugated sheet inside the head of a nail, is provided with insulation cage ring between the peg head of a nail and perforate corrugated sheet.Both ensure that the bonding strength of peg and corrugated sheet, in turn ensure that carrying out smoothly of welding of peg.
As preferably, longitudinal corrugated sheet is crossing with horizontal corrugated sheet forms cross unit.Cross unit is for arranging peg position.
As preferably, the quantity being welded with peg in cross unit is more than one.According to the needs of actual conditions, the quantity of peg can be selected.
As preferably, the peg crossed-symmetrical welding in cross unit.Be symmetrically welded effective warpage preventing component.
As preferably, the position of perforate is positioned at longitudinal corrugated sheet and horizontal corrugated sheet contact surface scope.
The welding detection method of multilayer crossing waveforms steel plate composite component, comprises the following steps: a. welds the second peg of same diameter outward again at the head of a nail welding peg; B. welded section is cut off 3%-20%; C. drawing is carried out or/and crooked test to outside second peg.The second outside peg there will be the phenomenon of fracture at External Force Acting, if fracture cut-off part in stepb, then prove that welding of peg is qualified.If break at other positions, then prove welding of peg existing defects.
As preferably, detection method is sampling Detection.Sampling Detection compares and is applicable to Wavelike steel webplate.
According to technical scheme of the present invention, common corrugated sheet by simply arranged in a crossed manner, is formed combined member by multilayer crossing waveforms steel plate composite component.And corrugated sheet is welded and fixed with peg each other, ensure that integrally-built rigidity, make component have stable usability.In addition, the welding detection method of multilayer crossing waveforms steel plate composite component, is effectively detected by the mode being welded with the second peg, ensure that the weld strength of peg and corrugated sheet, ensure that the quality of integrated member simultaneously.Multilayer crossing waveforms steel plate composite component and welding detection method thereof solve corrugated sheet each other cannot the difficult problem of veneer compound, revolutionary breakthrough has been had in corrugated sheet application, the specific bellows-shaped of steel plate makes virtual thickness increase, the radius of gyration increases, rigidity increases thereupon, and multilayer crossing waveforms steel plate composite component has each rigidity to equilibrium, the present invention makes the scope of application of corrugated sheet be expanded.
