[0012] FIG. 1 illustrates an example of a flame-retardant fastener according to the present invention.

[0013] Referring to FIG. 1, the flame-retardant fastener comprises a disc-shaped contact head (11); an opening (13) formed inside the contact head (11); an insertion leg (14) extending from the contact head (11) in a hollow cylinder shape connected to the opening; and a fixing tip (15) formed at the end of the insertion leg (14), and at least the contact head (11) and the insertion leg (14) are made of flame-retardant polyethylene material.

[0014] The contact head (11) may have a disc shape overall, and an inlet (13) may be formed in the central part of the contact head (11). A circular separating band (12) is formed between the contact head (11) and the inlet (13) to ensure that the fastener is stably fixed in a predetermined position. A hollow cylindrical insertion leg (14) may be formed from the lower surface of the contact head (11), and the cylindrical shape inside the insertion leg (14) may be connected to the inlet. A fixing tip (15) in the shape of a truncated cone may be formed from the end of the insertion leg (14), and a guide path may be formed inside the fixing tip (15) along the longitudinal direction. The fastener may have the function of firmly joining and fixing a wall or similar plate material, and a fixing means such as a nail may be inserted through the inlet (13), and the fixing means may be located inside the insertion leg (14). In this state, pressure is applied to the fixing means with various compression guns, such as an air compression gun or a gunpowder gun, so that the front part of the fixing means protrudes outward through the fixing tip (15), and the fixing means can be fixed to a solid wall.

[0015] Building members secured by fasteners may be exposed to various forms of fire or combustion conditions, and it is advantageous for the fasteners to be non-combustible, semi-combustible, or flame-retardant. To this end, at least a portion of the fastener may include a flame-retardant material, for example, the contact head (11) and the insertion leg (14) may include a flame-retardant material. Alternatively, since the fastener is integrally molded, the entire fastener may include a flame-retardant material. The fastener may be made of a synthetic resin material, for example, polyethylene or a similar synthetic resin material. Specifically, the fastener may be made of a mixture of HDPE (High Density Polyethylene), LLDPE (Linear Low Density Polyethylene), and PE (polyethylene), or a similar PE material. LDPE may be used instead of LLDPE, but LLDPE may be used to improve the strength and gloss of the fastener. In the manufacturing process of the fastener, a flame-retardant material may be added to the PE masterbatch, and, for example, the flame-retardant material may be at least one selected from the group consisting of antimony trioxide, halogen compounds, phosphorus compounds, aluminum trioxide, and magnesium hydroxide. Alternatively, the flame-retardant material may include an inorganic clay nanoparticle material such as montmorillonite or a fluorine compound. The fastener may include various types of flame-retardant materials depending on the field of application. The flame-retardant material may be added to PE in an amount of 0.5 to 30 wt% of the total weight of PE, and may be added in an amount of 0.1 to 20 wt% of the total weight of the fastener formed from HDPE / LLDPE / PE, but is not limited thereto.

[0016] FIG. 2 illustrates an example of a uniform contact wing formed on a flame-retardant fastener according to the present invention.

[0017] Referring to FIG. 2, it further includes a plurality of uniform contact wings (23_1 to 23_L) formed along the circumferential surface of the inlet (13). A circular inlet (13) may be formed in the central part of the upper surface of the disc-shaped contact head (11), and a circular separation band (12) may be formed on the outside of the inlet (13). The inlet rim formed around the separation band (12) and the inlet (13) may be structured to protrude in a circular band shape from the upper surface of the contact head (11), and the inlet rim and the separation band (12) may be connected to each other by a protruding band (21_1 to 21_K) extending in the radial direction. A plurality of protruding bands (21_1 to 21_K) may be formed along a uniform circumferential angle, and a plurality of divided regions may be formed along the circumferential direction by the plurality of protruding bands (21_1 to 21_K). A fixing hole (22_1 to 22_M) may be formed in each divided area. A plurality of protrusions may be formed on the upper surface of the contact head (11), and the plurality of protrusions may be formed in various parts of the upper surface of the contact head (11) in a semi-spherical or similar shape. A plurality of uniform contact wings (23_1 to 23_L) may extend from the periphery of the inlet (13) toward the center of the inlet (13). Each uniform contact wing (23_1 to 23_L) may be in the shape of an arrow or a similar shape, and a through hole may be formed by the end portion of each uniform contact wing (23_1 to 23_L). Such uniform contact wings (23_1 to 23_L) prevent air leakage when the air compression gun is inserted, while simultaneously ensuring that the front portion of the air compression gun inserted into the interior of the inlet (13) remains aligned with the path formed inside the insertion leg. By this, fastening means such as nails are secured to the building member in a predetermined direction.Various structures can be formed to allow the fastener on the upper part of the contact head (11) to be stably connected, and the present invention is not limited thereto.

[0018] FIG. 3 illustrates an example of a fixing means insertion structure of a flame-retardant fastener according to the present invention.

[0019] Referring to FIG. 3, limiting wings (31_1 to 31_K) may be formed on the outer circumferential surface of the insertion leg (14) and the fixing tip (15), and a guide hole (32) may be formed along the interior of the fixing tip (15).

A certain portion of the fixing means (41) may be inserted into the interior of the insertion leg (14). The contact head (11) is attached to the surface of the insulation material (S), and an air gun (43) can be prepared. The air gun (43) can apply pressure to the fixing means (42) by discharging air at a constant pressure through the outlet. The air gun (43) can apply a constant pressure, for example, continuously, and in the case of a solid wall (W), it is difficult for the fixing means (42) to be inserted into the wall (W) at once, and in such cases, pressure can be applied to the fixing means by the air gun (43) continuously in 1 to 3 times. Referring to FIG. 4 (b), the fixing means (42) is inserted into the interior of the insertion leg (41), and air pressure at a constant pressure from the air gun (43) can be applied to the fixing means (42), thereby allowing the fixing means (42) to be inserted into the wall (W). As shown in FIG. 4 (c) and (d), the fixing means (42) can be fully inserted into the wall (W) so that the insulation material (S) can be stably bonded and fixed to the wall (W).The fastener according to the present invention is made of a flame-retardant material so that it does not burn even when the wall (W) or insulation material (S) is in a high-temperature state, thereby reducing the risk of fire. The fastener can fix the insulation material (S) to the wall (W) in various ways, and the present invention is not limited by this. Although the insulation material (S) is presented and described in the embodiment of FIG. 4, building members having various structures can be fixed to a wall, floor surface, or ceiling surface by the fastener according to the present invention.
