The application discloses a shear connector, a steel-concrete composite beam containing the shear connector and a construction method of the steel-concrete composite beam. The shear connector comprises an inverted truncated cone type cylinder (7), a stiffener, a cover plate, a penetrating steel bar (8) and a high-strength bolt (21); the stiffener comprises an integrally formed stiffener bottom plate (13) and a stiffener side plate (14), the size of the stiffener bottom plate is consistent with the size of the lower opening of the cylinder, and the stiffener bottom plate is attached to the lower opening of the cylinder; the stiffener bottom plate is provided with a second connecting hole for connecting the high-strength bolt; the stiffener side plate is arranged around the stiffener bottom plate and is attached to the inner wall of the cylinder; the height of the stiffener side plate is lower than that of the first connecting hole; the cover plate covers the upper opening of the cylinder; the penetrating steel bar transversely passes through the cylinder through the first connecting hole and leaves a connecting section on each side of the cylinder; and the high-strength bolt connects the stiffener bottom plate through the second connecting hole. The application realizes the disassembly and replacement of each component of the shear connector and the prefabricated bridge deck; and the structure form and stress performance of the shear connector are optimized.

This application provides a pipe connection structure and frame. The pipe connection structure includes a first pipe, a second pipe, and a connector. The first pipe defines a first flow path and at least one first mounting hole; the second pipe defines a second flow path and at least one second mounting hole; the connector passes through the first and second mounting holes sequentially, and the connector defines a hollow channel that communicates with the first and second flow paths respectively. By using a connector that passes through the first and second mounting holes sequentially to connect the first and second pipes, thermal stress caused by thermal expansion and contraction at the weld joint of the first and second pipes can be avoided. This ensures that the connection between the first and second pipes remains structurally stable even under high-temperature operating environments, extending the service life of the pipe connection structure.

This invention provides a multicolor light source based on an anisotropic conductive film, comprising: a plurality of light-emitting panel packages, wherein each light-emitting panel package includes: a light-emitting panel configured to emit light; a lens holder configured to support a coupling lens and having a window, wherein each window is aligned with at least one light-emitting panel; and a coupling lens disposed on the lens holder and configured to transmit light emitted by the light-emitting panel; a circuit board configured to electrically connect the light-emitting panel to a motherboard; and a motherboard bonded to and electrically connected to the circuit board via the anisotropic conductive film. This invention allows the use of multiple monochromatic light-emitting panels to provide a mixed-color light source, such as a white light source, while also reducing the size of the light source or display.
