Problems solved by technology

[0003] The disadvantages of the above-mentioned structure are: 1. When in use, the force acts on the aluminum plate surface of the stone honeycomb panel. Due to the low strength of the aluminum plate surface, the use of the above-mentioned structure is greatly limited; 2. The screw rod 20 has no Positioning can be relatively rotated, when the fastening nut 10 is screwed, the nut 10 will drive the screw rod 20 to rotate together, so that the installation between the stone honeycomb panel 40 and the pendant 50 is not firm

Embodiment Construction

[0037] Such as figure 1 , figure 2 and image 3 Shown is a preferred embodiment of the present invention, an embedded nut for a stone honeycomb panel, including a cylinder 2 with a base 1 and an anti-rotation ring 3 . The base 1 is connected with the inner end of the cylinder 2, and the cylinder 2 forms an internally threaded hole 21. The improvement of the present invention is that the anti-rotation ring 3 is sleeved on the cylinder 2 , the anti-rotation ring 3 is positioned on the base 1 , and an upturned angle 34 is formed on the anti-rotation ring 3 . The anti-rotation ring 3 of the present invention can be fixed in the stone honeycomb panel 8 together with the cylinder 2 and the base 1, and snapped into the honeycomb panel 82 by means of the upturned angle 34, effectively preventing the entire embedded nut from being stuck in the stone honeycomb panel 8 Rotate so that the present invention will not be driven to rotate together when screwing and cooperating with the f...

Abstract

The invention discloses an embedded nut used for a stone cellular board. The embedded nut comprises a cylinder provided with a base and an anti-rotation ring, wherein the base is connected with the inner end of the cylinder, an internal thread hole is formed on the cylinder, the anti-rotation ring is sleeved on the cylinder and located on the base, and an upwards warped angle is formed on the anti-rotation ring. According to the invention, rotation of the whole embedded nut in the stone cellular board can be effectively avoided, so that when the embedded nut is screwed and matched with a fastening bolt, the embedded nut cannot be driven to rotate, thus the installation between the stone cellular board and a pendant is quicker and firmer.

Description

technical field [0001] The invention belongs to the technical field of building fasteners, in particular to a pre-embedded nut for a stone honeycomb panel. Background technique [0002] In the prior art, the installation of the hanger 50 on the stone honeycomb panel 40 is realized by means of the nut 10 , the screw rod 20 and the expansion member 30 . Such as Figure 4 As shown, the outer end of the screw 20 has a threaded section 201 and the inner end has a bolt head 202; the expansion member 30 includes a flat pad 301 and an expansion tube 302, and the expansion tube 302 is provided with a slit that is conducive to expansion, and the expansion member 30 is sleeved on the On the screw rod 20 , the inner end of the expansion tube 302 is against the bolt head 202 ; the nut 10 is screwed on the threaded section 201 , and the nut 10 is against the flat washer 301 . During installation, drill a hole on the stone honeycomb panel 40, put the expansion member 30 on the screw rod 2...
