Embodiment 1

[0020] Multi-layer cross corrugated steel plate composite member, including longitudinal corrugated plate 1, transverse corrugated plate 2, peg 4, longitudinal corrugated plate 1 and transverse corrugated plate 2 intersected, the trough or crest of longitudinal corrugated plate 1 and the crest of transverse corrugated plate 2 Or the troughs intersect and contact each other, and there are holes on the corrugated plate, and the diameter of the holes is greater than or equal to the rod diameter of the peg 4 .

[0021] The net length of the peg 4 is greater than or equal to the thickness of the perforated corrugated plate.

[0022] The stud 4 is welded with a stud machine to the corrugated plate in the other direction through the opening.

[0023] The nail cap of the stud 4 is located outside the perforated corrugated plate, and the inner side of the cap is in contact with the perforated corrugated plate, and an insulating isolation ring 5 is provided between the stud cap and the ...

Embodiment 2

[0029] A welding detection method for a multi-layer cross corrugated steel plate composite member, comprising the following steps:

[0030] a. Weld the second stud 6 of the same diameter outside the cap of the welded stud 4;

[0031] b. Cut off the welding section by 3%-20%;

[0032] c. Perform a pull or / and bend test on the outer second peg 6 .

[0033] The detection method is sampling detection.

Abstract

The invention relates to a multi-layer crossed corrugated steel plate composite component. According to the multi-layer crossed corrugated steel plate composite component, ordinary corrugated plates simply cross to form the combined component, and are welded and fixed through studs, and therefore the rigidity of the whole structure is guaranteed, and the component is stable to use. Furthermore, a method for welding detection of the multi-layer crossed corrugated steel plate composite component can effectively detect the welding strength of the studs and the corrugated plates, and guarantees welding quality and the quality of the whole component. The multi-layer crossed corrugated steel plate composite component and the method for welding detection of the multi-layer crossed corrugated steel plate composite component solve the problem that corrugated plates can not be combined in a fitting mode, are revolutionary in the corrugated plate application field, and expand the using range of the corrugated plates.

Description

technical field [0001] The invention relates to a composite structure of steel plates and a detection method, in particular to a composite component of multi-layer cross corrugated steel plates and a welding detection method thereof. Background technique [0002] With the continuous development of bridge structures in our country, new bridge structure forms are constantly emerging, and the world's first corrugated steel web bridge, which was first proposed and built by France, was introduced to Japan for development and further optimization. The bridge type was introduced in the 19th century. However, ordinary corrugated plates generally adopt a single-layer structure, and the form is relatively simple. Moreover, it has always been a difficult problem to laminate multi-layer corrugated boards with each other, and has not been effectively solved. Contents of the invention [0003] The present invention is proposed to solve the shortcomings of the existing corrugated plate...
