Problems solved by technology
In the traditional prefabricated shear wall structure, the vertical joint connection is mainly through the reserved steel bar of the prefabricated shear wall, which is connected with the longitudinally stressed steel bar at the vertical joint position, and then the formwork is erected and the concrete is poured afterwards. This vertical joint connection technology exists The following problems: the connection form is single, the steel bar conne

The invention provides a prestressed shear wall and vertical joint combining-connecting structure. The prestressed shear wall and vertical joint combining-connecting structure comprises at least two prestressed shear walls, two pieces of embedded profile steel and one fixing assembly. The embedded profile steel is embedded into the side walls of the prestressed shear walls, and the two pieces of embedded profile steel are arranged between the two prestressed shear walls and are fixed by the fixing assembly. The fixing assembly comprises two clamping plates, multiple hoop bars, multiple bolts and at least four longitudinal bars. The web plates of the two pieces of embedded profile steel are connected through the front clamping plate, the back clamping plate and the bolts. The four longitudinal bars are arranged along the connecting cross sections of the two pieces of embedded profile steel in a central symmetry mode, and the hoop bars are welded on the front clamping plate and the back clamping plate and are in bound connection with the longitudinal bars. The invention further provides a construction method of the prestressed shear wall and vertical joint combining-connecting structure. The prestressed shear wall and vertical joint combining-connecting structure is large in bearing capacity, good in anti-seismic property, superior in integrality, convenient to construct, good in construction quality and good in fireproof performance.
Description
technical field [0001] The invention relates to the technical field of prefabricated concrete structures in civil engineering, in particular to a prefabricated shear wall vertical joint connection structure and a construction method thereof. Background technique [0002] The traditional cast-in-place construction method has a low degree of industrialization, poor construction conditions, time-consuming and laborious, common quality problems are difficult to eradicate, and safety accidents occur from time to time, which is not conducive to energy conservation and environmental protection. The use of prefabricated structures can save energy, water, and materials, greatly reduce construction waste, reduce noise pollution, reduce labor consumption and intensity, effectively improve the construction environment, and improve project quality. The application of prefabricated concrete structures can achieve the goal of energy saving and emission reduction, improve the quality of lif...
