The invention discloses a built-in vibrating device based on sleeve post-grouting construction. The device comprises a vibrating ring, a plurality of limiting supports and a vibration excitation device, wherein the vibration ring comprises a convex nozzle and a vibration main ring, the vibration excitation device comprises a clamping nozzle and an internal vibration excitation system, and the clamping nozzle is meshed with the convex nozzle to enable the vibration main ring to vibrate under the action of the internal vibration excitation system. The limiting support comprises a rectangular groove and a rubber limiting plug and is used for fixing the vibration ring. The device has the advantages of being convenient to install and easy to operate, the compactness of the grouting material forsleeve post-grouting construction can be effectively improved, and the connecting quality of components is guaranteed.
Description
technical field [0001] The invention belongs to the field of prefabricated node construction, and in particular relates to a built-in vibrating device based on post-sleeve grouting construction. Background technique [0002] In recent years, prefabricated buildings have attracted people's attention due to their green environmental protection, short construction period, and high comprehensive economic benefits, and have been vigorously developed with national support. The prefabrication of each component is completed in the factory, and the assembly is completed on site, so that the connection between various parts cannot be connected in the same way as the traditional cast-in-place structure. At present, the main connection method of components is the grouting sleeve connection, and its construction technology is divided into the first grouting method and the second grouting method. The grouting construction first refers to laying the grouting layer in advance, and then gro...
