Problems solved by technology

In order to solve this problem, it is necessary to arrange an appropriate amount of horizontal steel bars. These steel bars have a single function and are often not in the same plane as the distributed steel bars when binding, which is difficult to bind

Embodiment Construction

[0022] Below in conjunction with the embodiment shown in the accompanying drawings, the utility folding shape is further described.

[0023] The cutting track of the steel plate by the CNC machine tool is a centrally symmetrical figure, and after one cutting of the steel plate, two identical steel beam webs 1 with folded tooth-shaped shear connectors can be obtained. A rolling machine is used to alternately roll out shear connectors 2 with a certain kink angle toward the left and right sides. The shape of the shear connector 2 is changeable, and its bending angle facing out of the plane can be adjusted according to the actual situation.

[0024] figure 1 It is a schematic diagram of the shear connector in the present invention.

[0025] On the premise of ensuring the shear bearing capacity and ductility of the shear connectors, a folded toothed shear connection with better economic performance and more convenient construction has been developed. Main train of thought of th...

Abstract

The invention provides a steel-concrete shear connector and a preparation method thereof. The steel-concrete shear connector comprises a zigzag tooth-shaped shear connector (4) and shear reinforcements (5), the zigzag tooth-shaped shear connector (4) is located at the top of a steel beam web (6), and the zigzag tooth-shaped shear connector (4) is used for connecting a concrete slab (1) and a steelbeam; the zigzag tooth-shaped anti-shearing connecting pieces are alternately bent towards the left side and the right side by a certain angle so as to resist lifting between concrete and a steel beam. And the zigzag tooth-shaped shear connector (4) is obtained by cutting a steel plate by a numerical control machine tool and then alternately rolling folded angles towards the left side and the right side on a rolling machine. Compared with a traditional anti-shearing connecting piece, the steel-concrete shear connector has the advantages that the construction process is greatly simplified on the basis that effective anti-shearing connection of the steel concrete is guaranteed, and the steel-concrete shear connector has excellent economical efficiency.

Description

technical field [0001] The invention belongs to the field of bridge engineering in civil engineering, and relates to a shear-resistant connector. Background technique [0002] At present, the composite structure is widely used in the bridge structure. It makes full use of the advantages of the two materials, so that the structure obtains greater rigidity and bearing capacity. Shear connectors are generally effective in transferring shear forces between steel and concrete, enabling the two materials to work together. [0003] For a long time, people's concept of shear connectors is a third material independent of steel and concrete, mainly including studs, PBL shear connectors, and section steel. A common disadvantage of these connectors is that they complicate the construction process of the composite structure. For example, studs, which are the most widely used at present, require special equipment to weld them to steel beams during construction. Considering that the shea...
