Description

Technical Field

[0001] The utility model belongs to the technical field of nail fastening, and in particular relates to an anti-rotation structural nail. Background Art

[0002] With the development of society and the continuous innovation of various industries, nail shooting has been more and more widely used in the field of building decoration. Among them, in order to facilitate construction, the ceiling nail structure composed of nails and fastening accessories has also emerged.

[0003] At present, there are many technologies related to ceiling nails. For example, the patent document with the announcement number CN209875668U discloses a nail, which includes a gunpowder nail and a steel frame (fastening accessory) fixed on the gunpowder nail. After the steel frame is fixed to the base by the gunpowder nail, the steel frame can be used to fix other components, so as to facilitate construction. The theoretical effect of this type of nail is: after the nail is fixed to the base, the nail cap applies pressure to the fastening accessory so that the fastening accessory is fixed to the base. However, in the actual construction process, due to the great differences in the strength of the base structure and the different shooting power of the nail shooter, when the nail is driven into the base using the nail shooter, some nails will not be able to fully enter the base, which results in the nail cap being unable to apply pressure to the fastening accessory. In addition, after the nail is fired, the nail will also expand the through hole of the fastening accessory. This causes the fastening accessory to be loose, that is, the fastening accessory can rotate around the nail rod, which in turn causes the fastening accessory to be unable to be positioned as required, affecting the construction. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned technical problems existing in the prior art and to provide an anti-rotation structural nail. The key improvement point of the utility model is that anti-rotation ribs are provided on the nail rod. Even if the nail is not completely fixed to the base, the anti-rotation ribs can effectively prevent the fastening accessories from rotating, thereby ensuring the effective positioning of the fastening accessories and the smooth progress of the construction.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An anti-rotation structural nail comprises a nail body and a fastening accessory. The nail rod of the nail body is evenly provided with anti-rotation ribs protruding from the surface. The anti-rotation ribs are straight ribs / oblique ribs arranged along the axial direction of the nail body, and the straight ribs / oblique ribs are parallel. The fastening accessory is interference fitted on the lower part of the nail rod. After the nail body is driven into a base, the rotation of the fastening accessory can be limited by the anti-rotation ribs.

[0007] The nail rod is a straight rod or a reduced diameter rod. When the nail rod is a straight rod, the fastening accessories are fixed on the anti-rotation ribs at the lower part of the nail rod; when the nail rod is a reduced diameter rod, a reduced diameter section is provided at the lower part of the nail rod, the anti-rotation ribs are located above the reduced diameter section, and the fastening accessories are fixed below the reduced diameter section.

[0008] The cross section of the anti-rotation rib is rectangular, triangular or arc-shaped.

[0009] The spacing between the anti-rotation ribs is 0.2-2 mm.

[0010] When the anti-rotation rib is an oblique rib, the angle between the oblique rib and the axis of the nail body is 1-20 degrees.

[0011] The advantages of adopting the utility model are:

[0012] 1. The key improvement of the utility model is that anti-rotation ribs are provided on the nail rod. According to the nails with anti-rotation ribs, during actual construction, even if the nails are not completely fixed to the base (that is, the distance between the nail cap and the base is greater than the thickness of the fastening accessory), the fastening accessory can be positioned and prevented from rotating under the limiting effect of the anti-rotation ribs, which is not only conducive to ensuring the effective positioning of the fastening accessory, but also conducive to ensuring the smooth progress of the construction.

[0013] 2. The utility model fixes the fastening attachments at different positions according to whether the nail rod is a straight rod or a reduced diameter rod, which has the advantage of facilitating good positioning of the anti-rotation structural nail and the nail shooter. Specifically, during fastening, the product can be well positioned with the base, so that the axis of the nail shooter and the axis of the nail body are perpendicular to the plane of the base, thereby improving the fastening success rate.

[0014] 3. The utility model sets the cross section of the anti-rotation rib to be rectangular, triangular or arc-shaped. The advantage is that after the nail is fastened to the base, under the action of power, the periphery of the through hole of the fastening accessory will form a cross-sectional shape opposite to the cross-sectional shape of the nail body and be embedded in the nail rod, thereby achieving an effective anti-rotation effect.

[0015] 4. The utility model sets the spacing between the anti-rotation ribs to 0.2-2 mm, which not only makes the anti-rotation ribs have a certain structural strength, but also enables multiple anti-rotation ribs to simultaneously play an anti-rotation role for the fastening accessories, which is beneficial to improving the anti-rotation effect.

[0016] 5. In the utility model, when the anti-rotation ribs are oblique ribs, the angle between the oblique ribs and the axis of the nail body is set to 1-20 degrees, which is conducive to obtaining a better anti-rotation effect.

[0017] 6. Since the utility model is provided with anti-rotation ribs on the nail body, the surface of the cement matrix is ​​less damaged during tightening. In addition, the ribs can also increase the contact area between the nail body and the cement matrix, thereby also improving the bonding force between the nail body and the matrix.
