Problems solved by technology

[0002] The utility model patent application document with application number 200920306229.2 discloses a ceiling embedded part; in this technology, "the threaded hole is preset with a threaded plug", and the installation and removal of the threaded plug are very troublesome; concrete muddy water It is easy to immerse into the threaded plug and the gap of the threaded hole; in the rough construction environment of the construction site, the threaded plug is easily covered by concrete muddy water, and it is difficult to open the threaded plug after the concrete muddy water dries and solidifies
[0003] The invention patent application document with the application number: 202010051783.1 discloses a ceiling embedded part of the ceiling radiation system and its construction method; in its specification [0007], "the sealing device can also be made of foam filled in the embedded nut, The foam plastic can be filled into the nut by polyurethane foam, which prevents the concrete from entering the nut during the pouring process. Before installing the screw rod, the foam can be pulled out from the nut with a hook, or the easy compressibility of the foam can be used , directly install the screw in the nut, and squeeze the foam in it to the top of the nut"; the foam sticking into the threaded hole will become difficult to clean, and it is not easy to be completely squeezed to the top of the nut, inside the rotation groove of the threaded hole If any material or impurities are stuck, it is difficult to screw in the threaded rod without cleaning it. Even if it is forced to be screwed in, it is very laborious and the work efficiency is very low.
[0004] In the prior art, the screwed-in length of the threaded rod depends on how deep the threaded hole of the pre-embedded nut in the ceiling is; if the depth of the threaded hole is set shallow, the screwed-in depth of the threaded rod will be shallow, and the threaded rod is not suitable for short and shallow in ceiling construction. Screw in and out of the threaded hole to adjust up and down, the construction flexibility of the ceiling threaded rod is limited; the depth of the threaded hole is set deep, and the threaded hole tapping is more difficult and costly during the production process; the depth of the threaded hole is set deep, and the threaded rod is screwed in Increased difficulty

Embodiment approach 1

[0030] Other embodiment 1: the head of the threaded hole plug 5 with a head is designed to be non-circular, and the size of the head is larger than the major diameter of the internal thread of the threaded hole 3; the head of the threaded hole plug 5 with a head can completely cover the threaded hole 3; The lower end of the nut cylinder 2 and the template are pressed against the head of the headed threaded hole plug 5 to form a seal to the threaded hole 3 .

Embodiment approach 2

[0031] Other embodiment 2: the head of the threaded hole plug 5 with a head can be designed into a flat cylindrical shape, a cylindrical shape, a flat round head shape, a round head shape, a flat semi-round head shape, a semi-round head shape, a mushroom head shape, an umbrella shape, a conical shape, Flat square shapes, square shapes, flat hexagonal shapes, hexagonal shapes, and other obvious variations all serve the same purpose.

[0032] The 5 heads of threaded hole plugs with a head are designed into a flat semicircular shape, a semicircular shape, a mushroom head shape, an umbrella shape, a conical shape, etc. These threaded hole plugs with a head are the thickest in the middle part of the 5 heads, and gradually become thinner around the head. The effective extruded part is the plug head minus the part covering the threaded hole 3.

Embodiment approach 3

[0033] Other embodiment 3: The sealing ring 6 can be designed to surround the plug in a cylindrical shape, surround the plug in a semicircular shape, surround the plug in a conical shape, surround the plug in a triangular shape, surround the plug in a square shape, and surround the plug in a square shape, and the tail of the plug is conical Other obvious variations such as raised, semicircular raised at the end of the plug, bulged at the end of the plug, etc. all serve the same purpose.
