Problems solved by technology
The stud connection is mainly to directly weld the shear studs and the steel frame beams together, set the alveolar at the precast concrete shear wall, and use the alveolar anastomosis studs to connect. High precision requirements in the docking process, which is not conducive to on-site construction
The existing bolt connections are mainly steel plate connectors. In this way, the steel plate connectors and steel beams are welded together, and the embedded steel plates in the precast concrete shear walls are connected horizontally with high-strength bolts. Many bolt holes require high processing and installation precision, and the installation of horizontal bolt connections is unfavorable due to the influence of the self-weight of steel beams and shear walls

Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with embodiment.
[0026] combine Figure 1 ~ Figure 3 As shown, a connector for the connection between an assembled prefabricated concrete shear wall and a steel beam, including: I-shaped steel frame beam 1, bolt 2, T-shaped steel plate connector 3, steel plate 4, concrete shear wall 5; in the factory , the flange 31 of the T-shaped steel plate connector is fixed to the bottom of the I-shaped steel frame beam 1 through a plurality of 10.9-grade high-strength bolts, and the number of high-strength bolts can be determined according to the actual bearing capacity requirements. For the T-shaped steel plate connector 3 and The I-shaped steel frame beam 1 is fastened to meet the needs of use, and the lower part of the steel plate 4 is pre-embedded in the concrete shear wall 5; at the construction site, the lower part of the beam rib 32 of the T-shaped steel plate connector and the upper part of th...

The invention discloses a connecting piece between a fabricated precast concrete shear wall and a steel beam. The connecting piece comprises a steel frame beam, a bolt, a T-shaped steel plate connector, a steel plate and a concrete shear wall, wherein a flange of the T-shaped steel plate connector is fixedly connected to the lower side of the steel frame beam, the lower portion of the steel plate is pre-buried in the body of the concrete shear wall, and the lower portion of a beam rib of the T-shaped steel plate connector is fixedly connected with the upper portion of the steep plate; a good synergistic effect can by generated by the steel frame beam and precast concrete arranged inside, and connection is more reliable; a definite force transferring route is obtained, horizontal shear force is transmitted to the pre-buried steel plate of the concrete shear wall by the steel frame beam through the T-shaped steel plate connector, so that the integrity of connection between the fabricated precast concrete shear wall and the steel frame beam is guaranteed; installation is convenient and quick, bolt connection is adopted, construction quality can be guaranteed, the construction speed can be increased, field wet construction is reduced, industrial production is easy to achieve, and construction progress is accelerated; ductility, anti-seismic property and repairability are high.
Description
[0001] Technical field: [0002] The invention relates to the technical field of building structure connectors, in particular to a connector for connecting an assembled prefabricated concrete shear wall to a steel beam. [0003] Background technique: [0004] With the continuous advancement of the new urbanization process, vigorously developing green buildings and promoting construction industrialization have become an important direction for the development of the current construction industry. Due to the advantages of high material strength and recyclability, steel structures are in line with the development trend of green, energy saving and environmental protection. [0005] The steel frame structure has the advantages of large space, flexible structure layout, good seismic performance, short construction period, small structure weight, recyclable steel, easy reconstruction and demolition, etc. It is currently the most widely used structural form in multi-story buildings.
