Telescopic hanging lamp embedded assembly

Abstract

The invention provides a telescopic hanging lamp embedded assembly. The telescopic hanging lamp embedded assembly comprises a core mold, a sleeve and a hanging nail. The sleeve is arranged on the periphery of the neck and the tail of the hanging nail. An inner pore of the sleeve comprises a small end and a big end. The aperture of the big end of the inner pore of the sleeve is matched with the tail of the hanging nail. The length of the big end of the inner pore of the sleeve is greater than the axial size of the tail of the hanging nail. The hanging nail can axially move relative to the sleeve. The sleeve is internally provided with an inner pore shoulder. The inner pore shoulder is used for preventing the hanging nail from getting out from the sleeve in the direction far away from the center of a wallboard. The telescopic hanging lamp embedded assembly provides an axial expansion space for the hanging nail through the sleeve with a stepped hole; when the hanging nail extends out completely, the head of the hanging nail from which the core mold is removed extends out of the sidewall of the corresponding wallboard so as to facilitate connection between the head of the hanging nailand a lifting tool. Moreover, the hanging nail can be pulled out together with the core mold, and the core mold can also being pulled out along with the hanging nail and then is dismantled. The lifting tool is quite fast and convenient to connect, and the core mold is quite fast and convenient to dismantle. The telescopic hanging lamp embedded assembly has little influence on the quality and the structural strength of the prefabricated wallboard.

Description

technical field [0001] The invention relates to prefabricated component hoisting equipment in the construction field, in particular to a telescopic pre-embedded hanger assembly. Background technique [0002] In the production process of prefabricated wall panels, it is necessary to lift the flat prefabricated wall panels after pouring, so that the prefabricated wall panels can be rotated 90 degrees around the landing point to achieve vertical storage. Some prefabricated wall panels will install pre-embedded hanging nails near the side wall, and install a hemispherical mandrel around the head of the pre-embedded hanging nails. The straight surface of the hemispherical mandrel is flush with the side wall of the prefabricated wall panel. When removing the hemispherical mandrel to expose the head of the pre-embedded hanging nail, the hanger can be connected. In order to prevent interference with other prefabricated wall panels, the heads of the hanging nails of the existing pref...

Problems solved by technology

[0002] In the production process of prefabricated wall panels, it is necessary to lift the flat prefabricated wall panels after pouring, so that the prefabricated wall panels can be rotated 90 degrees around the landing point to achieve vertical storage. Some prefabricated wall panels will install pre-embedded hanging nails near the side wall, and install a hemispherical mandrel around the head of the pre-embedded hanging nails. The straight surface of the hemispherical mandrel is flush with the side wall of the prefabricated wall panel. When removing the hemispherical mandrel to expose the head of the pre-embedded hanging nail, the hanger can be connected. In order to prevent interference with other prefabricated wall panels, the heads of the hanging nails of the existing prefabricated wall panels are all lower than the side wall of the wall panel. In order to prevent the impact on the structural strength of the prefabricated wall panels, the volume of the hemispherical mandrel cannot be set too large, which makes the space around the hanging nails for installing lifting fixtures limited after the hemispherical mandrel is removed. It is inconvenient to connect the lifting fixture and the hanging nail, and the prefabricated wall panel is prone to chipping during the lifting process, which affects production efficiency and product quality

Chinese patent 201810555459.6 discloses a pre-embedded fixing structure for round-headed nails. This patent proposes a solution to facilitate the disassembly of the rubber mandrel. The rubber mandrel can be reused. problem with connection
