Abstract

The invention discloses a girder drilled template tooling. The tooling comprises a rectangular overlay panel. Drilling sleeves arranged in rectangular arrays are arranged on the surface of the overlaypanel. A first reinforcing plate and a second reinforcing plate are fixed to the surface of the overlay panel. A first alignment groove, a second alignment groove, a third alignment groove, a fourthalignment groove, a fifth alignment groove, a sixth alignment groove and the second reinforcing plate are formed in or arranged on the four sides of the overlay panel correspondingly. The first alignment groove is located in a width side of the overlay panel. The second alignment groove is located in the other width side of the overlay panel. The third alignment groove and the fifth alignment groove are located in one length side of the overlay panel. The fourth alignment groove and the sixth alignment groove are located in the other length side of the overlay panel. By means of the girder drilled template tooling, requirements for manufacturing precision, hole group connecting precision and the like of curved steel bridges can be met.

Description

technical field [0001] The invention relates to the technical field of steel box combined beam hole making, in particular to a steel beam drilling model tooling and a steel box combined beam hole making method. Background technique [0002] At present, in the development of urban construction, urban steel bridges are generally built on rivers, roads and overpasses, overpasses and pedestrian bridges where roads cross highways and railways. It meets the needs of urban transportation and residents' travel, taking into account the requirements of aesthetics and flood control. [0003] Steel girder and steel cap beam technology of curved steel-concrete combined bridge. Steel girders are divided into two structural forms: steel box composite beam and steel plate composite beam. The alignment and structure of this type of steel bridge are extremely complex, and the cross-section is a variable cross-section structure. The bottom plate and web plate connection between the steel ma...
