Embodiment Construction

[0027] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0028] figure 1 Shown:

[0029] It includes a steel web 1, and a streamlined zigzag shear connector 2 is cut from the top of the steel web by a CNC machine tool. The cutting of the steel web can be completed in a factory, which is simple and convenient.

[0030] Including the zigzag shear connector 2, the zigzag shear connector 2 is located on the steel web 1, and its basic shape is figure 2 Streamlined as shown, the shape can also be stretched lengthwise. At the same time, the basic shape of the zigzag shear connector 2 is a centrally symmetrical figure, that is, two identical steel webs 1 with the zigzag shear connector 2 can be obtained in one cut.

[0031] Including the shear reinforcement 3, the shear reinforcement 3 is arranged between the zigzag shear connectors 2, and one or more shear reinforcements can be arranged at each interva...

Abstract

The invention provides a serrated steel-concrete shear connector, and belongs to the field of civil engineering structural engineering. The serrated steel-concrete shear connector comprises a steel web, and streamline-shaped serrated shear connectors are formed by cutting operation at the top end of the steel web through a numerical control machine tool. The serrated steel-concrete shear connector comprises the serrated shear connectors, the serrated shear connectors are located on the steel web, and the serrated shear connectors are basically respectively of a streamline shape. The serrated steel-concrete shear connector comprises shear reinforcements which are arranged between the adjacent serrated shear connectors, one or more shear reinforcements can be arranged at the interval between every two adjacent serrated shear connectors, and the shear reinforcements are vertically located at inflection points of cutting lines. The serrated steel-concrete shear connector comprises concrete, the concrete is poured in a closed space formed by formworks and the steel web, and the shear reinforcements and the serrated shear connectors need to be poured into the concrete. The serrated shear connectors are innovatively directly arranged on the steel web, the machining, manufacturing and construction processes of traditional shear connectors are omitted, construction is convenient and quick, and connecting transmission between steel and concrete is reliable and effective.

Description

technical field [0001] The invention belongs to the field of civil engineering structure engineering, and in particular relates to a shear-resistant connector. Background technique [0002] Composite structures are widely used in building structures. It makes full use of the advantages of steel and concrete—steel bears tensile stress, and concrete bears compressive stress, so that the structure obtains greater rigidity and bearing capacity. In order for the two materials to work together, steel and concrete require shear-resistant connections to transmit the shear forces between the two materials. [0003] At present, there are many forms of shear connectors, which can be divided into rigid connectors and flexible connectors according to the deformation capacity. Rigid connectors include square steel, T-shaped steel, horseshoe steel, etc.; flexible shear connectors include studs, bending bars, and PBL shear connectors. Relatively speaking, rigid connectors have large rigid...
