Problems solved by technology
The steel bars at the joints of this kind are bound in the form of binding, which will greatly reduce the space at the joints, resulting in insufficient mortar or concrete filling, which will affect the shear resistance and durability of the studs; The force situation is very complicated, and the joint is the weakest link of the structure. The steel bar binding is also a weak connection. Even the mechanical performance and durability of the structure; the traditional jointing process is relatively complicated, which cannot effectively guarantee the durability and safety of the structure, and will affect the construction progress

The utility model relates to an assembly type steel-concrete composite beam joint structure with higher integrity. The assembly type steel-concrete composite beam joint structure comprises profile steel, a first composite beam, a second composite beam, a middle groove, shear nails, epoxy mortar, shear mortar and connecting parts, the first composite beam is arranged on the profile steel, the second composite beam is arranged on the first composite beam, a middle groove is formed in the first composite beam and the second composite beam, a shear nail is arranged on the middle groove, one end of the shear nail is fixedly connected with the profile steel, and epoxy mortar is used for connecting the first composite beam and the second composite beam. The shear mortar is used for filling the middle groove, and the connecting parts are arranged on the first composite beam and the second composite beam. The invention further provides a manufacturing method of the assembly type steel-concrete composite beam joint structure which is more integral. The overall performance of the structure is improved, the shear resistance of the composite beam structure can be improved, the stress condition of the joint is simplified, the durability of the joint is improved, and the construction efficiency is improved.
Description
Technical field [0001] The present invention belongs to the field of compositions bridge seam structure belonging to technical field, particularly relates to a more holistic Prefabricated steel-concrete structure of the seam and method of manufacture of composite beams. Background technique [0002] In recent years, steel concrete composite beam bridge construction bridge in our country occupies an important position in the production of steel-concrete composite beam structure, often using prefabricated factory, on-site installation method, wet joints are unavoidable. However, the prior art generally use concrete slab overlap the steel beam, the steel banding reservation, then the concrete slab and the steel beam with a cavity surrounded epoxy mortar or concrete to fill the high strength. The kinds of steel joints using banding form, make space seams greatly reduced, resulting in insufficient perfusion chamber mortar or concrete, the influence of shear studs performance and durab...
