Novel grouting sleeve assembly and prefabricated part steel bar connecting structure
The invention belongs to the technical field of fabricated buildings, and particularly relates to a novel grouting sleeve assembly. The novel grouting sleeve assembly aims to overcome the defects thatan existing grouting sleeve adopts shear keys to ensure firm connection, the number of the shear keys needs to be large, and the size of the sleeve is large. According to the technical scheme, the novel grouting sleeve assembly comprises a first sleeve, a second sleeve and a connecting sleeve, wherein the first sleeve is provided with a plurality of first threaded holes which are distributed in the circumferential direction and are equal in diameter, and the center distances between the first threaded holes and the first sleeve are different; the second sleeve is provided with second threadedholes, and the diameters of first external threads are equal to the diameters of second external threads; and the connecting sleeve is provided with internal threads matched with the first external threads and the second external threads. The novel grouting sleeve assembly has the beneficial effects that the requirement of large positioning errors of an existing prefabricated part steel bar is met, firm connection of steel bars with different positioning errors is realized, the operation is simple, and the connection is firm.
本发明属于装配式建筑技术领域，具体涉及一种新型灌浆套筒组件。针对现有灌浆套筒采用剪力键保证牢固连接，剪力键的数量需要较多，使得套筒尺寸较大的不足，本发明采用如下技术方案：一种新型灌浆套筒组件，所述灌浆套筒组件包括：第一套筒，所述第一套筒具有周向分布的多个等径的第一螺纹孔，多个所述第一螺纹孔与所述第一套筒间的中心距不同；第二套筒，所述第二套筒具有第二螺纹孔，所述第一外螺纹和所述第二外螺纹等径；连接套筒，所述连接套筒具有与所述第一外螺纹和所述第二外螺纹配合的内螺纹。本发明的有益效果是：满足现有预制构件钢筋较大定位误差的要求，实现不同定位误差的钢筋的牢固连接，操作简单，连接牢固。
