Description

목재용 앵커 볼트{Anchor Bolt for Wood}Anchor bolt for wood {Anchor Bolt for Wood}

본 발명은 목재용 앵커 볼트에 관한 것으로, 보다 상세하게는 앵커 몸체가 목재를 뚫고 들어가서 견고하게 고정되도록 선단에 드릴 날을 형성하고, 주연부에 뾰족한 나사산을 형성한 목재용 앵커 볼트에 관한 것이다.The present invention relates to an anchor bolt for wood, and more particularly, to an anchor bolt for wood in which a drill bit is formed at the tip of the anchor body so as to penetrate through the wood and firmly fixed thereto, and a sharp thread is formed in the periphery.

일반적으로 조립식 가구 혹은 목재 도어의 경우 조립과 분해를 용이하게 함과 아울러 그 결합력을 우수하게 유지시키기 위해 앵커와 앵커 볼트를 이용하고 있다.In general, for prefabricated furniture or wooden doors, anchors and anchor bolts are used to facilitate assembly and disassembly as well as to maintain their bonding strength.

종래 앵커는 도 1 및 도 2에서와 같이 내부로 조립볼트(20)가 삽입되어 나사 체결되도록 관통구멍(31)이 형성되고, 관통구멍(31)의 선단에는 조립볼트(20)의 조임 작업에 의하여 외주연에 돌기 형상으로 다수 돌출된 걸림편(33)이 조립구멍 내벽에서 강하게 압착될 수 있도록 절개부(32)가 트여지는 구조로 이루어져 있으며, 이러한 종래의 앵커는 그 자체로 목재를 뚫을 수 있는 수단이 없어서 앵커를 사용하기 위해서는 우선 목재에 앵커가 투입된 구멍을 우선 천공하고, 그 구멍 내부로 앵커를 삽입시킨 후 조립볼트(20)를 조립하도록 되어 있다.1 and 2, a conventional anchor has a through hole 31 formed therein so that an assembly bolt 20 is inserted and screwed in. An end of the through hole 31 is fastened to a fastening operation of an assembly bolt 20 The cutout 32 is formed so that a plurality of protruding hooks 33 protruding from the outer periphery of the hole can be strongly pressed on the inner wall of the hole. The conventional anchor can pierce the wood itself In order to use the anchor, there is no means to drill the hole. First, the hole into which the anchor is inserted is first drilled in the wood, and the anchor is inserted into the hole, and then the assembly bolt 20 is assembled.

그러나, 상기한 바와 같이 미리 구멍을 천공하는 경우 앵커의 지름보다 크게구멍을 천공하여야만 앵커를 삽입할 수 있고 이로 인하여 조립볼트로 조립하여 앵커의 선단 직경이 확장되더라도 걸림편이 목재로 투입되는 치수가 작아서 목재와의 결합력이 약하게 되고, 이와 같이 결합력이 약해지면 목재로 이루어진 가구 혹은 문의 사용시에 상기 결합부위에 유격이 발생하면서 문이 처지거나 가구가 삐걱되는 등의 문제점이 발생되었다. However, in the case of perforating the hole in advance, it is necessary to drill a hole larger than the diameter of the anchor so that the anchor can be inserted. Therefore, even if the diameter of the tip of the anchor is enlarged by assembling with the assembly bolt, When the bonding strength is weakened, the joining force with the wood becomes weak, and when the furniture or the door made of wood is used when the joining force is weakened, a gap is formed at the joining portion, and the door is sagged or the furniture is squeezed.

또한, 구멍을 앵커직경보다 작게 천공하는 경우에는 앵커의 투입이 불가능하므로 새롭게 구멍을 뚫어야 하고 이로 인하여 작업이 번거로운 문제점이 있었다.Further, when the hole is drilled smaller than the diameter of the anchor, it is impossible to insert the anchor. Therefore, there is a problem that the hole must be newly drilled and the operation is troublesome.

본 발명은 상기한 문제점을 해결하기 위한 것으로, 드릴날과 뾰족한 나사산을 형성하여 앵커 몸체가 목재를 뚫고 들어가서 견고하게 고정되도록 함으로서, 조립시에 별도의 구멍천공작업이 요구되지 않도록 하여 체결과정이 용이하도록 하는 데 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a drill bit and a sharp thread to form an anchor body to penetrate and firmly fix the wood, The purpose is to make.

또한, 상기한 바와 같이 목재와 앵커가 견고하게 고정되면서 긴밀하게 밀착되므로 사용 중 앵커와 목재 사이에 유격이 발생하지 않아서 가구나 문의 결합력이 약해지지 않도록 하는 데 다른 목적이 있다.In addition, as described above, since the wood and the anchor are firmly fixed and tightly adhered to each other, there is another purpose of preventing the joint between the anchor and the wood from weakening due to the absence of clearance between the anchor and the wood during use.

상기한 목적을 달성하기 위한 본 발명의 특징은, 중심에 나사부이 형성된 체결홈이 축방향으로 형성되고, 외주연에 뾰족한 나사산이 형성되며, 원추형으로 형성된 선단 외주에 드릴 날이 형성되고, 선단은 텐션을 갖도록 축방향으로 절개부이 형성된 앵커몸체; 상기 앵커몸체 내부로 나사결합되는 결합 조립볼트;로 구성되어 앵커몸체가 직접 목재를 뚫고 들어가면서 긴밀하게 고정되는 목재용 앵커 볼트에 있다.According to an aspect of the present invention for achieving the above object, there is provided a drill according to the first aspect of the present invention, wherein a fastening groove formed with a threaded portion in the center is formed in the axial direction, a sharp thread is formed on the outer circumference, a drill is formed on the outer periphery of the conical tip, An anchor body formed in the axial direction so as to have an incision; And an engaging assembly bolt threaded into the anchor body, wherein the anchor body is anchored in the wood anchor bolt that is directly tightened while penetrating the wood.

상기에서 앵커 몸체의 외주에는 나사산과 드릴 날 사이에 고정력을 강화하도록 선단측으로 경사면을 갖는 고정돌기가 더 돌출형성되어 앵커볼트의 후진을 방지한다.In this case, a fixing protrusion having an inclined surface is further protruded on the outer periphery of the anchor body to reinforce the fixing force between the thread and the drill blade, thereby preventing the anchor bolt from moving backward.

상기한 바와 같은 구성을 갖는 본 발명에 의하면 드릴날과 외주연에 형성된 나사산에 의하여 앵커몸체가 목재를 뚫고 전진할 수 있게 되어 별도의 구멍천공작업 없이도 목재에 앵커몸체를 고정할 수 있게 되므로 조립작업이 간편한 효과가 있고, 종래 구멍 천공작업 중 구멍치수 불량으로 인한 앵커의 결합력 약화가 본 발명에서는 발생되지 않고 오히려 앵커몸체 외주면과 목재가 긴밀하게 밀착되므로 목재와 앵커볼트의 결합력 약화가 발생하지 않게 된다.According to the present invention having the above-described structure, since the anchor body can advance through the wood by the screw thread formed on the drill bit and the outer circumferential edge, the anchor body can be fixed to the wood without drilling another hole, The weakening of the anchor bonding force due to the hole size defect in the conventional hole drilling operation is not generated in the present invention but rather the outer peripheral surface of the anchor body is tightly adhered to the wood so that the bonding strength between the wood and the anchor bolt does not occur .

이로 인하여 목재나 가구 등은 최초 체결상태를 계속해서 유지할 수 있게 되어 종래와 같이 오랜 사용으로 인하여 삐걱거림이나 삐뚤어지는 등의 문제점이 발생하지 않게 된다.As a result, the first fastening state of the wood or the furniture can be continuously maintained, and problems such as squeaking and creasing due to the long use are prevented.

또한, 상기한 고정돌기가 앵커의 후진을 방지하므로 앵커와 목재의 결합력을 보다 강화할 수 있게 되는 효과가 있다. In addition, since the fixing protrusion prevents the back of the anchor, the coupling force between the anchor and the wood can be further enhanced.

3 and 4 are views showing an anchor bolt of the present invention

이하 본 발명의 실시예를 첨부한 도면을 참조하여 살펴본다.
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 3 및 도 4는 본 발명에 따른 앵커볼트를 나타내는 단면도로서, 크게 앵커몸체(110)와 조립볼트(120)로 구성된다.
3 and 4 are cross-sectional views illustrating an anchor bolt according to the present invention. The anchor bolt 120 includes an anchor body 110 and an assembly bolt 120.

상기에서 앵커 몸체(110)는 나사부(112a)이 형성된 체결홈(112)이 축방향으로 형성되고, 외주연에 뾰족한 나사산(114)이 형성되며, 원추형으로 형성된 선단 외주에 드릴 날(116)이 형성되고, 선단은 텐션을 갖도록 축방향으로 절개부(118)이 형성된다.The anchor body 110 is formed with an engagement groove 112 formed with a screw portion 112a in the axial direction and a sharp thread 114 formed on the outer periphery of the anchor body 110. A drill blade 116 is formed on the outer periphery of the conical tip, And the tip is formed with an incision 118 in the axial direction so as to have a tension.

상기에서 외주연에 형성된 나사산(114)은 목재와의 결합을 위하여 그 돌출정도를 최소 2mm이상으로 한다.The screw thread 114 formed on the outer circumferential edge in this case has a protruding degree of at least 2 mm for joining with the wood.

또한, 상기한 절개부(118)은 체결홈(112)과 서로 연통될 수 있는 치수로 형성한다.
In addition, the incision portion 118 is formed to have a dimension that can communicate with the engaging groove 112.

한편, 상기 앵커 몸체(110)의 외주에는 나사산(114)과 드릴 날(116) 사이에 고정력을 강화하도록 선단측으로 경사면을 갖는 고정돌기(119)가 더 돌출형성되어 앵커 볼트의 후진을 방지한다.
On the outer circumference of the anchor body 110, a fixing protrusion 119 having an inclined surface toward the tip side is further protruded to reinforce the fixing force between the thread 114 and the drill blade 116 to prevent the anchor bolt from moving backward.

그리고 상기 조립볼트(120)는 외주연에 나사부가 형성되어 앵커몸체(110)의 체결홈(112) 내부로 나사결합된다.
The assembly bolts 120 are screwed into the fastening grooves 112 of the anchor body 110 with threaded portions formed on the outer periphery thereof.

이와 같은 구성을 갖는 본 발명의 목재용 앵커 볼트의 실시예를 살펴보면, 우선 목재에 앵커 몸체(110)를 회전시켜 드릴 날(116)이 목재에 구멍을 뚫으면서 나사산(114)에 의하여 앵커몸체(110)가 전진되도록 하여 목재(130)에 앵커몸체(110)를 고정한다.In the embodiment of the present invention, the anchor body 110 is rotated on the wood, and the drill blade 116 is drilled in the wood, and the anchor body 114 110 are advanced so that the anchor body 110 is fixed to the wood 130.

이 후 조립볼트(120)를 앵커몸체(110)의 체결홈(112)으로 조립하면 조립볼트(120)는 전진하면서 앵커몸체(110)의 절개부(118)를 도 4에 나타내는 바와 같이 확장하게 되고 이로 인하여 고정돌기(119)가 목재(130)에 막히면서 앵커몸체(110)의 체결상태를 보다 견고하게 한다.The assembling bolt 120 is assembled into the engaging groove 112 of the anchor body 110. When the assembling bolt 120 is advanced, the incision portion 118 of the anchor body 110 is expanded as shown in FIG. 4 The fixing protrusion 119 is clogged with the wood 130 and the anchor body 110 is further tightened.
