Precast concrete shear wall fabricated type connection joint

Abstract

The invention belongs to the technical field of fabricated type concrete shear walls, and relates to a precast concrete shear wall fabricated type connection joint. An outwardly extended connecting steel plate is pre-embedded at the bottom end of an upper precast concrete shear wall, an outwardly extended connecting steel plate is pre-embedded at the top end of a lower precast concrete shear wall,the upper and lower precast concrete shear wall connecting steel plates are connected with each other through high-strength bolts, and the outsides of the connecting steel plates are wrapped with concrete. The upper and lower precast concrete shear walls are connected with each other by adopting high-strength bolts, the construction is simple, force transferring is reliable; the quality of connection is convenient to inspect, the finished product quality is controllable; and the construction installation is rapid, the efficiency is high, and the requirement of fabricated type buildings is met.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete shear wall assembly, and relates to a prefabricated concrete shear wall assembly connection node. Background technique [0002] Prefabricated building is a construction method in which prefabricated beams, slabs, columns, walls and other building components are produced in the factory, and after maintenance and acceptance, they are transported to the site for installation and construction. The prefabricated building has the characteristics of standardized design of building components, factory processing, and prefabricated construction, which is conducive to reducing environmental pollution caused by construction, shortening the construction period, and saving manpower and material resources. [0003] In building structures, shear walls mainly bear horizontal and vertical loads caused by wind loads or earthquakes. In the prefabricated concrete structure, the horizontal connection o...

Problems solved by technology

However, in practical application, there are many shortcomings in the grouting sleeve connection technology. First, the precast concrete shear wall has a large amount of reinforcement, and it is difficult to connect the sleeve and the steel bar during construction; It is difficult to guarantee the construction quality due to slurry and void phenomenon; the third is that the sleeve process is complicated and the cost is high, which increases the overall cost of prefabricated concrete buildings

Patent CN107460969A discloses a new type of assembly method for prefabricated concrete shear walls. This connection method eliminates the grouting sleeve, and the construction quality can be guaranteed. However, it is still necessary to bind steel bars and pour concrete on site during construction, and the site workload is large; patent CN207079756U discloses A dry-type connection method for concrete shear walls and walls. This method adopts the dry operation method without grouting on site, but there are still a lot of docking problems between the steel bars and sleeves during the construction process, and the construction is difficult.
