Description

Technology Field

[0001] The present invention relates to a magazine piece that is mounted on a magazine drill and used, and in particular, it improves workability and allows the magazine piece to maintain the function of a double edge even when it is a single edge, while enabling it to be used for various purposes. Background Technology

[0002] Currently, when performing interior and remodeling work at construction sites, especially in indoor spaces, partition walls are typically installed or ceiling tiles are installed. In such cases, individual screws are mostly used to secure the partition walls or ceilings.

[0003] However, when using individual pieces in this way, workability is poor, so to improve this, a magazine piece in which individual pieces are continuously mounted on a plastic strip is mounted at the entrance of the magazine drill, and when the magazine drill is pushed forward and pressed, the piece fastening operation can be performed quickly and continuously.

[0004] However, the form of these pieces has remained almost unchanged from the early days to the present, with single-edged pieces used for ceilings and double-edged pieces used for walls.

[0005] For reference, the usage method of these pieces is classified into single-edged and double-edged depending on the thickness of the steel plate to be mounted. Typically, single-edged pieces are used for thin steel plates of about 0.45T in lightweight steel frames and can be used when joining ceiling tiles, while double-edged pieces serve to penetrate the steel plate when it is thick and are usually used at construction sites when mounting partition walls on stud steel frames of about 0.8T to 1.0T.

[0006] In addition, when selecting and using such pieces, single-edged pieces are commonly used for lightweight steel plates, such as those with a thickness of 0.45T or less. This is because if a double-edged piece with a thick tip is used on a thin sheet, the double-edged piece cannot enter the correct position and is pushed slightly, causing the steel plate to spread out and reducing usage efficiency.

[0007] In addition, these single-edged or double-edged pieces have the same effective diameter of the threaded section, so when drilling a steel plate, the diameters of the threaded sections at the tip and the rear end are almost identical, which causes difficulties during the initial entry into the drilling process. Furthermore, after joining, the threaded section and the tip have the same diameter in the ground part of the steel plate, which leads to a problem of reduced bonding strength. Prior art literature delete The problem to be solved

[0010] Therefore, in this invention, a double-edged function is provided to a single edge so that it can be used on both thin and thick steel plates with just one piece, and the bonding strength is excellent even after joining. means of solving the problem

[0011] To this end, the screw threads formed in multiple stages are provided at the rear end of the single blade provided at the tip of the screw portion of the piece and are repeatedly formed in low and high directions. In this state, the first and second threads located at the rear end of the single blade are provided with grooves of a certain depth on the same line or offset from each other, so that the single blade facilitates the grinding of steel plates, etc., during assembly through the grooves provided on the first and second threads.

[0012] At this time, the same effect can be produced even if the height of the threads provided on the screw part of the piece is made the same, while the parts with sheaths on the first and second threads are deviated from the same line.

[0013] In addition, the threaded portion of the piece is provided with vertical grooves to allow dust and other debris that may be generated as the piece is joined to the base material to be discharged.

[0014] In addition, the screw portion of the piece is provided with a stepped front portion equipped with a cutting edge and a rear portion equipped with a head portion, and the front portion is provided with a smaller effective diameter than the rear portion, thereby minimizing the initial resistance to joining when penetrating the steel plate, while also enhancing the joining strength after joining. Effects of the invention

[0015] Therefore, although it is a single-edged blade, it can perform the same function as a double-edged blade, resulting in excellent workability and ease of piece production.

[0016] In addition, by providing sheaths on the first and second threads of the screw section even though it is a single blade, it is possible to easily drill through the base material with little force in a 0.8T steel plate for walls without using a double-edged screw.

[0017] As a result, the manufacturing process for the pieces is reduced by one step, lowering costs; furthermore, from the worker's perspective, the distinction between ceiling and wall pieces is eliminated, making work easier and eliminating the burden of double inventory.

[0018] In addition, the threaded portion of this piece is provided with a vertical groove to facilitate the discharge of dust that may be generated while being ground by a sheath.

[0019] In addition, the front end, which is divided into a threaded section and a step section, has the advantage of minimizing entry resistance when penetrating the base material, while the rear end is combined with a relatively thick threaded section to provide a strong fixing force.

Specific details for implementing the invention

[0021] First, the terms used in the specification and claims of the present invention should not be interpreted as being limited to their dictionary meanings. Based on the principle that the inventor may appropriately define the concepts of the terms to best describe their invention, they should be interpreted in a meaning and concept consistent with the technical spirit of the present invention.

[0022] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing.

[0023] The present invention will be described in detail below based on the attached drawings.

[0024] As illustrated in FIGS. 1 to 4, the present invention is composed of a piece (100) comprising a head portion (110), a screw portion (120) having a certain length and having peaks (122) and valleys (123) at regular intervals, and a tip portion (130) that can be made of a single edge.

[0025] In the present invention, as shown in FIGS. 1 and 2, the continuously repeating ridges (121) and valleys (122) forming the screw portion that is formed in multiple stages at the rear end of the single blade (131) provided at the front end of the screw portion (120) of the piece are formed continuously with the first ridge (121a) being low and the second ridge (121b) being high. In this state, the first ridge (121a) and the second ridge (121b) located at the rear end of the single blade (1301) are provided with sheaths (123) so that they can grind iron plates, etc., either on the same line as shown in FIGS. 1a and 2a or staggered as shown in FIGS. 1b and 2b, thereby making it easy to grind when combined with the base material.

[0026] In addition, the same effect can be produced even if the height of the ridges (121) provided in the screw portion (120) is the same as in FIG. 1a and FIG. 2b, and the sheaths (123) are provided on the same line or staggered on the first and second ridges (121a, 121b).

[0027] At this time, the position of the above-mentioned sheath is best for cutting at the point where the angle of the screw thread (121) gradually rises and becomes horizontal.

[0028] In addition, the screw portion (120) of the piece (100) is provided with a step portion (140) to form a front portion (120a) equipped with a front blade portion (130) and a rear portion (120b) equipped with a head portion, and the front portion (120a) is provided with a smaller effective diameter of the piece (100) than the rear portion (102b), so that when the piece penetrates and joins a steel plate, the joining resistance is minimized at the initial stage of entry, and after joining, the friction surface is increased due to the rear portion (120b), which is relatively thicker than the front portion (120a), thereby increasing the joining force. Additionally, since a sheath (123) is formed on the first and second ridges (121a, 121b) of the front portion (120a), the entry of a thick steel plate is a single blade (131) without slipping, and the sheath allows for easy grinding and joining.

[0029] By using this step section (140), the stepped portion maintains a constant angle of inclination, thereby minimizing coupling resistance as it transitions from the front end (120a) to the rear end (102b).

[0030] In the present invention, the length of the front end (120a) is preferably shorter than the length of the rear end (120b), so as to facilitate penetration into the base material and to maintain strong support even when penetrating.

[0031] FIG. 2 shows that the step portion (140) separating the front portion (102a) and the rear portion (120b) of the screw portion (120) in the present invention is provided with an inclined width (a) at a certain angle, and screw threads (121) and grooves (122) can be provided at equal intervals along this inclined width (a).

[0032] As a result, the connection force between the front end (120a) and the rear end (120b) can be made excellent, and the slope width (a) of the step portion (140) allows for easy penetration even when penetrating the base material.

[0033] FIG. 3 shows that a groove (124) is formed vertically on the screw portion (120) of the present invention so that dust and other particles generated by grinding when joined to the base material can be easily discharged.

[0034] In the present invention, the depth of the cut (123) that is recessed and cut is preferably provided at a position higher than the bone diameter of the piece (100), preferably at a position lower than the outer diameter, and preferably at the same position as the effective diameter.

[0035] Although the present invention is described as enabling the function of a double edge while being composed of a single edge, by implementing the present invention on a double edge as well, it is possible to provide even superior bonding strength. Explanation of the symbols
