Description

Technology Field

[0001] The present invention relates to a system channel comprising a channel and a coupling member, and more specifically, to a system channel in which a serrated projection of a certain length is formed on the surface where the channel and the coupling member meet to firmly fix the coupling member and prevent slipping. Background Technology

[0002] Generally, various pipes and cables are installed in underground utility tunnels where ceilings, walls, or telecommunication facilities are installed in buildings. These pipes and cables are arranged at a certain distance from the ground or walls through channels connected to walls or H-beams.

[0003] In other words, a channel is a metal member fixed to the exterior walls or ceilings of a building, with a cross-section shaped like a "U" with one side open. To secure an attachment to such a channel, a portion of the attachment must be inserted into the channel and screwed in using bolts and nuts. However, using bolts and nuts to secure attachments resulted in long working times and issues such as the nuts and bolts becoming detached from the channel during the process.

[0004] Accordingly, a technology has recently been developed that allows for shortening work time and facilitating work by using a separate coupling member consisting of a lower part inserted into the interior of the channel and an upper part fixed to the upper surface of the channel. FIG. 6 shows a channel fastening device (100) according to the prior art, which includes a channel (110) that is extended in the longitudinal direction as shown and has an upper surface having a coupling slit (111) formed on the upper side, and a fastening member (120) that is coupled to the upper surface of the channel.

[0005] The above-mentioned fastening member (120) includes a fixing plate portion (121) that is in close contact with the upper surface of the channel, a T-bolt (122) comprising a threaded portion penetrating the fixing plate portion and a header portion integrally formed with the threaded portion, a nut (123) coupled to the threaded portion of the T-bolt, and an elastic member (124) coupled between the nut and the fixing plate portion to ensure that the fixing plate portion and the header portion are in close contact with the upper surface of the channel. Additionally, a first compression portion is formed on the upper surface of the channel and the lower surface of the fixing plate portion, and a second compression portion is formed on the lower surface of the channel and the upper surface of the header portion.

[0006] However, the conventional fastening member (120) had a problem in that the T-bolt (122) and the nut (123) were separated from the fixing plate (121), so it took a long time to combine both the T-bolt and the nut, and the height between the fixing plate (121) and the header part (122B) of the T-bolt was low, so the durability against lateral force was reduced, and the production process of the channel became complicated because sawtooth-shaped protrusions had to be formed on both the upper and lower surfaces.

[0011] A channel that extends in the longitudinal direction and has a longitudinal joining slit formed in the center of the upper surface; and

[0012] A coupling member comprising: a nut portion having a screw hole formed therein that is inserted into the interior of the channel through the coupling slit and into which a fastening bolt is screwed; and a nut fixing portion integrally coupled to the upper part of the nut portion and attached to the upper surface of the channel; wherein

[0013] A connecting rail extending a certain length from both sides of the connecting slit toward the inside of the channel;

[0014] It is characterized by including a first interlocking part formed integrally with the lower surface of the coupling rail and a plurality of toothed protrusions, and a second interlocking part formed integrally with one side of the upper surface of the nut part and having a plurality of grooves formed so that the protrusions of the first interlocking part can be inserted when the coupling member is inserted into the interior of the channel through the coupling slit and rotated 90° in the horizontal direction.

[0015] In the present invention, the channel is formed with a rectangular cross-section including left and right sides, a bottom surface, and a top surface, and a plurality of coupling holes are formed at regular intervals on the left and right sides and the bottom surface in a size and shape through which the fastening bolt can pass, and a rim extending inwardly to the channel along the inner circumference of the coupling holes is integrally formed.

[0016] The above nut portion includes a nut plate that is inserted into the interior of the channel through the coupling slit, can rotate in the width direction within the channel, and can be in close contact with the lower surface of the coupling rail, wherein the nut plate is made of a rectangular metal plate having a major axis and a minor axis, has a screw hole formed in the center for screwing a fastening bolt, has a coupling protrusion integrally formed at both ends in the major axis direction extending downward by a certain length, and has inclined surfaces formed at both ends in the minor axis direction to allow for smooth rotation within the channel.

[0017] The above nut part is made of metal, and the above nut fixing part is made of a plastic injection molded part having a certain elasticity.

[0018] The above nut fixing part comprises a fixing plate that is in close contact with the upper surface of the channel and has a through hole formed in the center through which the fastening bolt passes;

[0019] A cylindrical part of a certain height integrally formed on the lower surface of the above-mentioned fixing plate and having a hollow formed therein through which the above-mentioned fastening bolt passes;

[0026] According to the system channel of the present invention, since the nut portion is integrally fixed to the lower end of the coupling member, the structure is simple and the fastening time can be shortened. Since a coupling rail is located between the nut portion and the fixing plate portion, the durability against lateral forces is improved, and since a sawtooth-shaped protrusion is formed only on the lower surface of the coupling protrusion, the production process of the channel is simplified.

[0027] In addition, the system channel of the present invention has the effect of forming a serrated projection on the surface where the connecting rail of the channel and the nut part of the connecting member meet, thereby strengthening the connection between the channel and the connecting member and preventing the connecting member from slipping.

[0031] However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms, and the embodiments provided are merely to complete the disclosure of the present invention and to inform those skilled in the art of the reproduction of the invention, and the scope of protection of the present invention will be defined by the description in the claims.

[0032] Meanwhile, the terms used in this specification are for describing the embodiments and are not intended to limit the invention. In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. As used in this specification, "comprising" and / or "comprising" does not exclude the presence or addition of one or more other components, steps, operations, and / or elements to the mentioned components, steps, operations, and / or elements.

[0033] Hereinafter, a preferred embodiment of the system channel according to the present invention will be described in detail with reference to the attached drawings.

[0034] First, FIG. 1 is a perspective view showing the configuration and coupling relationship of a system channel according to the present invention, FIG. 2 is a perspective view showing a preferred embodiment of the coupling member shown in FIG. 1, and FIG. 3 is a cross-sectional view showing the coupling relationship between the channel and the coupling member shown in FIG. 1.

[0035] As described above, the system channel (1) according to the present invention comprises a channel (10) and a connecting member (20) connected to the channel (10).

[0036] The above channel (10) is a metal member that extends in the longitudinal direction, and a connecting slit (11) that is open in the longitudinal direction is formed on the upper surface.

[0037] The above-mentioned connecting member (20) is detachably connected to the upper surface of the channel (10) through the connecting slit (11), and is structured so that a fastening bolt (40) can be screw-connected.

[0038] Preferably, various types of attachments to be fixed to the channel (10) can be attached to the fastening bolt (40).

[0039] The above channel (10) is a metal member attached to the wall or ceiling of a building and has a square cross-section, and a connecting slit (11) of a certain width is formed in the longitudinal direction in the center of the upper surface so that the whole is formed in a 'U' shape.

[0040] A connecting rail (12) is integrally formed in the longitudinal direction on both sides of the connecting slit (11). The connecting rail (12) is formed by bending the leading edge of the upper surface downward for a certain length, and is formed parallel to both sides along the connecting slit (11). The connecting rail (12) serves to reinforce the strength of the upper surface of the channel (10) and to more firmly secure the connecting member (20).

[0041] In particular, a first interlocking part (13) consisting of a plurality of tooth-shaped protrusions is formed at the bottom of the coupling rail (12). The first interlocking part (13) is intended to firmly fix the coupling member (20) by preventing it from sliding. The protrusions of the first interlocking part (13) are not limited to tooth-shaped protrusions but can be formed in various shapes such as rhombus shapes or uneven surfaces. Additionally, a second interlocking part (26) corresponding to the first interlocking part (13) may be formed on the coupling member (20).

[0042] In addition, a plurality of coupling holes (15) are formed at regular intervals on the left and right sides and the bottom surface of the channel (10). Preferably, the coupling holes (15) can be formed in a size and shape through which a fastening bolt can pass. Also, two coupling holes (15) formed on the left and right sides of the channel (10) can be formed at corresponding positions so that one fastening bolt can pass through.

[0043] In addition, a rim (16) may be integrally formed in the coupling hole (15) to protrude inward. The rim (16) functions to reinforce the strength of the side and bottom surfaces of the channel (10). Preferably, the rim (16) may be made of a burr created when drilling the coupling hole (15).

[0044] Next, as seen in FIGS. 1 and 2, the coupling member (20) is detachably fixed to the channel through the coupling slit (11) of the channel (10) and is mainly composed of a nut part (21) and a nut fixing part (31).

[0045] The nut portion (21) is a part where the fastening bolt (40) is screw-coupled, and is inserted into the interior of the channel (11) through the coupling slit (11). The nut fixing portion (31) is a part that fixes the nut portion (21) so that it does not detach, and is fixed to the channel by being in close contact with the upper surface of the channel (10).

[0046] Preferably, the nut portion (21) is made of metal and includes a nut plate (22) and a coupling protrusion (24) having a size and shape that can be inserted into the interior of the channel (10) through the coupling slit (11) and rotate in a horizontal direction while inserted into the interior of the channel (10).

[0047] The nut plate (22) may be made of a rectangular metal block having a major axis and a minor axis, and a screw hole (23) is formed vertically in the center to allow the fastening bolt (40) to be screwed in. Preferably, a rim may be formed on the upper side of the fastening hole (23) that extends upward along the inner surface for a certain length. The rim is formed in a size and shape that can be inserted into the hollow formed in the cylindrical part (33) of the fixing plate (32) described later. Accordingly, the upper surface of the nut plate (22) comes into contact with the lower surface of the coupling rail (12).

[0048] A connecting protrusion (24a) (24b) is integrally formed on the lower surface of the nut plate (22). The connecting protrusion (24a) (24b) may be formed by extending downward for a certain length from both ends in the direction of the long axis. Accordingly, the fastening hole (23) is formed between the connecting protrusions (24a) (24b).

[0049] Additionally, inclined surfaces (25) may be formed at both ends of the short axis direction of the nut plate (22). The inclined surfaces (25) allow the nut plate (22) to rotate without colliding with the channel (10) when rotating horizontally inside the channel (10).

[0050] And on the upper surface of the nut plate (22), a second interlocking part (26) corresponding to the first interlocking part (13) formed on the coupling rail (12) is formed. The second interlocking part (26) is formed as a groove corresponding to the protrusion of the first interlocking part (13), and is formed so that the protrusion of the first interlocking part (13) can be inserted when the nut plate (22) rotates horizontally inside the channel (10). For example, the second interlocking part (26) is formed at both ends in the direction of the long axis of the nut plate (22) and is formed to be arranged in a direction parallel to the protrusion of the first interlocking part (13) when the nut plate (22) rotates horizontally inside the channel (10).

[0051] Meanwhile, the nut fixing part (31) is a plastic injection molded part and includes a fixing plate (32), a cylindrical part (33), a hook part (34), a folding plate (35), and a handle part (36) so as to fix the nut part (21) while in close contact with the upper surface of the channel (10).

[0052] As seen in FIGS. 1 and 2, the fixing plate (32) is made of a plastic plate of a certain thickness and is sized so as not to pass through the connecting slit (11), and a through hole is formed in the center through which the fastening bolt (40) can pass. The cylindrical part (33) is integrally formed on the lower surface of the fixing plate (32) and extends downward for a certain length, and a hollow is formed in the center so that the fastening bolt (40) can pass through.

[0053] The above hook portion (34) is integrally formed at the lower part of the upper cylindrical portion (33) and is a portion that extends downward for a certain length and includes two hooks (34a) (34b) that connect the connecting protrusion (24) of the nut portion (21). The hook (34) extends downward to wrap the side of the connecting protrusion (24) and extends inward from the bottom for a certain length to wrap the lower surface of the connecting protrusion (24).

[0054] The above folding plate (35) is formed integrally on both ends of one side of the above fixing plate (32) and is made of a plate of a certain size that can be folded up and down. The handle portion (36) is a part formed integrally by extending downward from the outer surface of the above folding plate (35) and is formed in a shape that can be grasped with fingers when folding the above folding plate (35). Therefore, when inserting the above coupling member (20) into the channel (10) through the above coupling slit (11) or rotating the coupling member (20) inserted inside the channel (10) through the above coupling slit (11) in a horizontal direction, the above folding plate (35) can be folded by grasping the handle portion (36) with fingers. In this way, by installing the folding plate (35) on the fixing plate (32), the operation of grasping or inserting the above coupling member (20) becomes easy.

[0055] More preferably, the folding plate (35) is integrally formed at both ends of the fixed plate (32) in the short-axis direction, and a folding groove (37a) and a folding line (37b) are formed between the folding plate (35) and the fixed plate (32). As shown in FIG. 6, the folding groove (37a) penetrates in an arc shape along the outer side of the cylindrical part (33), and the folding line (37b) is formed as a straight groove of a certain depth extending outward from both ends of the folding groove (37a). The handle part (36) is formed integrally by being bent downward from the outer surface of the folding plate (35), and is made of a size that can be inserted into the coupling slit (11).

[0056] More preferably, the hook portion (34) may consist of a pair of hooks (34a) (34b) that are extended downward by a certain length so as to wrap around the outer surface of the coupling protrusion (24). The hooks (34a) (34b) may be formed by extending downward to wrap around the side and bottom surfaces of the coupling protrusions (24a) (24b), respectively, and then extending inward to form a ledge of a certain length. Preferably, the hooks (34a) (34b) may be detachably fixed to the coupling protrusion (24) of the nut portion (21) by the elastic force of the plastic material.

[0057] More preferably, the cylindrical part (33) is formed between the fixing plate (32) and the hook part (34), has a hollow formed inside through which the fastening bolt (40) passes, and its outer surface is made of a cylinder of a size and shape that can rotate smoothly while inserted between the coupling rails (12).

[0058] The assembly and operation of the system channel (1) according to the present invention will be described below.

[0059] FIG. 3 shows the state in which a coupling member (20) according to the present invention is inserted into the interior of a channel (10) through a coupling slit (11), FIG. 4 and FIG. 5 show the state in which a coupling member (20) according to the present invention is rotated in a horizontal direction after being inserted into a channel (10), and FIG. 6 shows the state in which a coupling member (20) according to the present invention is slid along a coupling slit (11) while inserted into a channel (10).

[0060] First, the channel (10) according to the present invention can be installed in a vertical and horizontal direction on a wall or ceiling of a building. In addition, a plurality of connecting members (20) can be installed on the channel (10). The connecting members (20) can be fixed by inserting a nut part (21) into the interior of the channel (10) through a connecting slit (11) and then rotating it 90 degrees in a horizontal direction.

[0061] That is, when the worker holds the handle portion (36) with their fingers and presses it inward, both folding plates (35) rotate around the folding groove (37a) and folding line (37b) and fold upward, causing them to stand upright. In this way, the connecting member (20) is held with fingers so that the long axis direction of the nut portion (21) faces the length direction of the connecting slit (11), and then inserted through the connecting slit (11) into the inside of the channel (10). Then, when the connecting member (20) is rotated 90 degrees horizontally while the nut portion (21) is inserted into the inside of the channel (10) through the connecting slit (11), the long axis direction of the nut portion (21) becomes perpendicular to the length direction of the connecting slit (11).

[0062] Subsequently, when the worker removes their hand from the handle portion (36), the fixing plate (32) comes into close contact with the upper surface of the channel (10), and at the same time, the nut portion (21) is pressed upward by the elastic force of the fixing plate (32), so that the upper surface of the nut plate (22) comes into contact with the lower surface of the coupling rail (24), and the first interlocking portion (13) formed on the lower surface of the coupling rail (24) and the second interlocking portion (26) formed on the upper surface of the nut plate (22) are joined together. In this state, the coupling member (20) does not slide along the channel (10), so it can be firmly fixed.

[0063] Meanwhile, when changing the position of the coupling member (20), if the handle portion (26) of the coupling member (20) is grasped and the coupling member (20) is pressed downward, the fixing plate (32) bends and the nut portion (21) moves downward, and then the second interlocking portion (26) formed on the upper surface of the nut portion (21) and the first interlocking portion (13) formed on the lower surface of the coupling rail (24) are separated and spaced apart from each other.

[0064] Therefore, in this state, if the coupling member (20) is pushed in the longitudinal direction of the coupling slit (11), the coupling member (20) can be easily slid to a desired position. Then, if the handle part (36) is released again at that position, the second interlocking part (26) of the nut part (21) and the first interlocking part (13) of the coupling rail (24) are interlocked and fixed by the elastic force of the fixing plate (32).

[0065] Meanwhile, when the above-mentioned connecting member (20) is fixed at a desired position on the channel (10), the fastening bolt (40) is fixed by screwing it into the screw hole (23) of the nut part (21), and then a binding part such as a nut, clamp, hanger, or U-band is attached to the fastening bolt (40), and various attachments such as pipes or cables can be freely fixed and installed through these binding parts.

[0066] As such, the system channel (1) according to the present invention is composed of a channel (10) and a coupling member (20), and an interlocking portion consisting of a sawtooth protrusion and a groove is formed on the surface where the channel (10) and the coupling member (20) meet, thereby firmly fixing the coupling member (20) to the channel (10) and preventing it from sliding.

[0067] In addition, the coupling member (20) according to the present invention has the effect of easily fixing the nut part (21) inserted inside the channel (10) through the fixing part (31) that is in close contact with the upper surface of the channel (10), so that the structure is simple and installation is easy, and the position of the coupling member (20) can be freely adjusted by sliding the coupling member (20) while it is inserted into the coupling slit (11) when necessary.

[0068] Although the present invention has been described with reference to one embodiment illustrated in the accompanying drawings, it will be understood by those skilled in the art that various modifications and other embodiments are possible. Explanation of the symbols
