Detailed Description

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a pre-buried nut according to an embodiment of the present invention; fig. 2 is a front view of a pre-buried nut according to an embodiment of the present invention; fig. 3 is a bottom view of the embedded nut according to the embodiment of the present invention.

As shown in fig. 1, 2, and 3, the nut may be embedded in a concrete structure, and is used for installing various external devices and brackets after the concrete is solidified.

The embedded nut comprises a nut body 1 and a fixing plate 2 arranged on the nut body 1. The nut body can select suitable nut according to the particular case of construction, and is firm for the later stage installing support, optional long nut.

The fixing plate 2 is made of a steel plate, and a through hole 3 is formed in the center of the fixing plate 2. The fixed plate evenly sets up in 1 outer wall of nut body along circumferencial direction's a week, and the quantity of fixed plate is two at least. In order to facilitate the central axis of the nut body to be vertical to the surface of concrete when being embedded, the central axis of the through hole is on the same plane and vertical to the central axis of the nut body. In this embodiment, the quantity of fixed plate is two, all penetrates positioning steel bar 7 in two fixed plates, seeks suitable position ligature positioning steel bar 7 in original reinforcing bar in concrete structure, decides the vertical position of nut body 1 well.

Evenly be provided with location nail 4 on the bottom surface of the one end of nut body 1, the quantity of location nail 4 can be four in this embodiment, and four location nails evenly set up on the bottom surface of nut body 1. The location nail 4 can adopt the round nail, and the head of a nail welded fastening of round nail is on the bottom surface of nut body 1, and the nail pole of round nail is perpendicular with the bottom surface of nut body 1, and the length of round nail is decided according to the particular case of construction, and the nail pole of round nail can adopt thinner nail pole. When the positioning steel bars 7 are bound with the original steel bars in the concrete structure, the tops of the positioning nails 4 are nailed into the template of the concrete structure, the transverse position of the nut body is well fixed, and the thin nail rod cannot damage the template. After the transverse vertical position of the nut body is fixed, concrete can be poured, the nut body cannot deviate in the pouring process, the embedded position is accurate, and the working efficiency is improved.

Fixed plate, spacer bar and staple not only can fix a position, have still increased the anchor length of nut body, and it is pre-buried more firm, the withdrawal resistance is strong.

The position of the fixed plate of the outer wall a week that is located the nut body is not restricted to a height, and the one week fixed plate can be located the outer wall of nut body and keep away from the one end of location nail, also can be located the outer wall middle part of nut body, and is decided according to concrete structure's original reinforcing bar.

In order to prevent concrete from entering the nut body 1 during the concrete pouring process, a cylindrical plug 5 may be plugged inside the nut body 1. The length of the plug 5 is the same as that of the nut body 1, and the outer diameter of the plug 5 is the same as that of the nut body 1. One end of the plug 5 is provided with a plug cap 6, the outer diameter of the plug cap 6 is larger than the inner diameter of the nut body 1, the plug cap can be used for preventing concrete from entering a gap between the thread of the nut body 1 and the plug 5, the plug cap 6 is convenient to pull out the plug in a later stage, and construction speed is accelerated. The plug can be a rubber plug.

In this embodiment, the vertical direction is the direction of nut body axis, and the horizontal direction is the direction perpendicular to the axis.

The embedded nut according to the present invention is described above by way of example with reference to the accompanying drawings.
