Embodiment Construction
[0031] For the current traditional stud shear connectors, cylindrical head studs are used, and there are many unstressed sections, resulting in waste of materials, low bearing capacity and inability to prefabricate and assemble, which greatly affects the safety of the structure and the construction speed. The problem. The innovations of the novel shear connector disclosed by the present invention include the novel structure of the dumbbell-shaped studs and the ingenious arrangement of the studs, which overcome these two shortcomings, have good engineering value, and are worthy of vigorous promotion.
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0033] Such as Figure 1~Figure 7 The dumbbell-shaped stud shear ...

The invention relates to the technical field of bridges, and particularly relates to a dumbbell-shaped stud shear connector. The dumbbell-shaped stud shear connector comprises a steel beam, a prefabricated concrete bottom plate and studs, wherein the steel beam is I-shaped steel, the studs are arrayed on a flange plate of the steel beam in an m*n mode to form stud blocks, m and n are integers greater than 1, and the stud blocks are arranged at intervals; and the prefabricated concrete bottom plate is arranged on the steel beam, preformed holes are formed in the prefabricated concrete bottom plate, the preformed holes penetrate through the prefabricated concrete bottom plate, the positions and the sizes of the preformed holes correspond to those of the stud blocks, and mortar is poured intothe preformed holes. By means of the mode that the hole sites are reserved in the prefabricated concrete bottom plate, the fixing speed of the steel-concrete structure connecting piece is increased,the construction efficiency is improved, the studs are arranged according to the stud blocks, the shear capacity of the studs is improved, and the bearing capacity and safety of the structure are improved. The invention further provides a dumbbell-shaped stud shear connector construction method.
Description
technical field [0001] The invention relates to the technical field of bridges, in particular to a dumbbell-shaped stud shear connector and a construction method thereof. Background technique [0002] Stud connector is a form of shear connector that is widely used in steel-concrete composite structures. It is cheap and easy to construct, but it also has certain problems. The most notable problem is the shear resistance of the shear connector. Lower performance. The shear connector is an important part of the steel-concrete composite structure. The premise that the steel-concrete composite structure can play a structural load-bearing role is to connect the concrete slab and the steel beam as a whole through the shear connector, and coordinate the force. [0003] In the prior art, the traditional stud shear connectors use cylindrical head studs, which have many unstressed sections, resulting in waste of materials, low bearing capacity, and the inability to prefabricate and as...
