Embodiment Construction
[0018] Combine below Figure 1-3 The present invention will be described in detail. Such as figure 1 As shown, the present invention provides a shear connector for wood-concrete composite members, which is composed of a PZ type composite pin shear connector 1 and a tooth plate 2, and the tooth plate 2 is fixed on the PZ type composite pin shear connector. Bottom of connector 1.
[0019] PZ type composite dowel shear connector (Puzzle shape composite dowel) is a kind of composite dowel, this type of composite dowel can be produced by single wire cutting, with high production efficiency and good static and fatigue properties. Under the condition of the same structural size, the PZ type composite pin shear connector has better performance than other types of composite pin shear connectors, and can better meet the structural construction and force requirements. This application combines the PZ type combined pin shear connector and tooth plate together to form a new shear connec...

The invention discloses a shear connector for wood-concrete composite member. The shear connector for wood-concrete composite member is composed of a PZ-type composite pin shearing connector and a toothed plate, wherein the toothed plate is fixed on the bottom of the PZ-type composite pin shearing connector, a plurality of perforations are arranged on the toothed plate, and each perforation corresponds to a tooth for pressing the shearing connector into the wood. In a wooden structure of a concrete composite member, a plurality of the teeth are arranged in order to form the toothed plate. A PZ-type composite pin shear connector and a toothed plate are combined together to form a new shear connector, the shear connector has excellent static bearing capacity, slip resistance, pullout resistance and fatigue performance, and can transfer the shear force between the wood slab and the concrete composite member, prevent the concrete slab from being lifted, and meet the stress requirements ofthe structure.
Description
technical field [0001] The invention relates to the technical field of engineering structure connectors, in particular to a shear connector for wood-concrete composite components. Background technique [0002] Compared with traditional timber structures, the flexural bearing capacity and stiffness of timber-concrete composite components are greatly improved, and the fire performance is better. The wood-concrete composite member is a structural system in which wood and concrete members are combined by shear connectors and then jointly stressed. The shear connector is a key element in the wood-concrete composite member, which transmits the longitudinal shear force on the interface of the two materials and resists the relative displacement between the two material interfaces, so that the concrete is under compression while the wood member is in tension. form a combination. [0003] Commonly used MCL composite pin shear connectors, PBL shear connectors and other connectors are...
