Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, and in particular to a prefabricated shear wall connection structure without reinforcement bars on four sides. Background Art

[0002] The prefabricated shear wall structure system has been widely used in residential civil buildings due to its fast construction speed, energy saving, water saving, electricity saving and environmental protection. The prefabricated shear wall components are connected with composite beams and composite slabs through cast-in-place concrete to form a structural system with good seismic performance.

[0003] Shear walls without reinforcement on all four sides refer to the structural reinforcement inside them no longer protruding from the concrete structure like traditional prefabricated shear wall panels, which can reduce the workload of architectural design, reduce mold costs, and improve the utilization rate of transportation space. However, since the panel surface no longer protrudes from the reinforcement structure, the connection structure for on-site assembly is not perfect enough. For example, this type of shear wall is connected layer by layer in a high-rise building, and is usually positioned with the help of a reinforcement structure that continues to extend upward. However, before the concrete is poured, the positioning relationship between this type of shear wall and the reinforcement is weak. Therefore, a prefabricated shear wall connection structure without reinforcement on all four sides is urgently needed to solve the above problems. Utility Model Content

In this process, the rubber sleeve 20 can prevent the concrete from gripping the upper end of the first connecting rib 4; when the floor slab 16 is After shaping, the lifting member 21 is pulled upward, and the lifting member 21 drives the sliding ball 24 through the connecting rod 23 and is stuck in the upper end of the lifting groove 25, and drives each extrusion rod 22 to leave the upper horizontal periphery of the first connecting rib 4 or the second connecting rib 15. As a result, the upper sleeve connection force between the rubber sleeve 20 and the first connecting rib 4 or the second connecting rib 15 is greatly weakened, and then the lifting member 21 can be continued to be pulled to conveniently pull the rubber sleeve 20 out of the hole 17 formed on the floor slab 16. After that, the sleeve 5 is inserted into the hole 17 and connected to the end of the first connecting rib 4 therein, and then another group of first connecting ribs 4 are connected thereto, and then the wall panel 1 of a higher layer can be installed.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
