Description

세트 앵커 볼트 {Set anchor bolts}Set anchor bolts

본 발명은 세트 앵커 볼트에 관한 것으로 더욱 구체적으로는 확개부를 이중으로 형성함으로써 고정력을 향상시킬 수 있게 한 세트 앵커 볼트에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a set anchor bolt, and more particularly, to a set anchor bolt which is capable of improving fixing force by forming a double widening portion.

일반적으로 세트 앵커 볼트를 설치할 때에는 먼저 콘크리트 바닥이나 벽체와 같이 세트 앵커 볼트가 설치될 위치에 먼저 일정 깊이의 앵커설치공을 형성한 후 서로 나사 결합하는 볼트와 너트, 그리고 볼트와 너트 사이에 개입되어 볼트와 너트의 결합력에 의해 볼트 또는 너트에 구비된 경사돌편에 의해 확개되어 고정력을 발생시키는 소켓으로 구성되는 세트 앵커 볼트를 앵커설치공 내부에 투입하게 된다.
Generally, when installing the set anchor bolt, first, bolts and nuts which are screwed to each other after forming an anchor mounting hole of a predetermined depth at a position where the set anchor bolt is to be installed, such as a concrete floor or a wall, A set anchor bolt composed of a bolt or a socket which is widened by an inclined protrusion provided on the nut and generates a fixing force by a coupling force of the bolt and the nut is inserted into the anchor mounting hole.

이때, 볼트 또는 너트에 형성된 경사돌편은 앵커설치공 내부에 위치하게 하고, 앵커설치공 외부로 노출되는 볼트에는 피고정체의 결합부를 끼운 후, 볼트 너트를 서로 나사 결합함으로써 볼트와 너트의 체결력에 의해 볼트 또는 너트에 형성된 경사돌편이 소켓 내부로 투입되어 앵커설치공 내부에 투입된 소켓의 하단부를 확개시킴으로써 소켓의 확개부와, 앵커설치공 내주면 간의 강한 마찰력이 작용하여 견고한 고정력을 발생시키게 된다.
At this time, the oblique protrusions formed on the bolt or the nut are positioned inside the anchor mounting hole, and the bolts exposed to the outside of the anchor mounting hole are inserted into the bolts and the bolts are screwed to each other. The inclined stone piece formed on the bolt or nut is inserted into the socket and the lower end of the socket inserted in the anchor mounting hole is widened so that a strong frictional force acts between the enlarged portion of the socket and the inner circumferential surface of the anchor mounting hole.

그러나 위와 같은 종래의 세트 앵커 볼트는 볼트와 너트의 체결력에 의해 확개되는 소켓의 확개부가 소켓 하단부에만 위치함으로써 큰 고정력을 기대하기 어려운 문제점이 있었다.
However, in the conventional set anchor bolt as described above, it is difficult to expect a large fixing force because the widening portion of the socket, which is expanded by the fastening force of the bolt and the nut, is located only at the lower end of the socket.

또한, 세트 앵커 볼트를 설치하기 위하여 콘크리트 바닥이나 벽체에 앵커설치공을 형성하는 과정에서 앵커설치공의 내주면 일부가 파손되거나, 콘크리트의 양생 과정에서 생성된 기공에 의해 앵커설치공의 내주면에 홈이 생기는 경우도 있는데, 그와 같이 앵커설치공 내주면의 파손부 또는 홈부에 소켓의 확개부가 확개되는 경우에 소켓의 확개에도 불구하고, 확개된 소켓과 앵커설치공 내주면 간의 마찰력이 작용하지 않아서 고정력이 발생하지 않는 문제점도 빈번하였다.
In addition, in order to install the set anchor bolts, a part of the inner circumferential surface of the anchor mounting hole may be damaged in the process of forming the anchor mounting hole on the concrete floor or the wall, or a groove may be formed on the inner circumferential surface of the anchor mounting hole by the pore generated in the concrete curing process In this case, when the widening portion of the socket is expanded in the breakage portion or the groove portion of the inner circumferential surface of the anchor mounting hole, the frictional force between the widened socket and the inner circumferential surface of the anchor mounting hole does not act despite the expansion of the socket, The problem was not frequent.

첨부된 도면들 중에서 동일한 구성 요소들은 가능한 어느 도면에서든지 동일한 부호를 사용하고 있음을 유의해야 하며, 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 또는 공지 구성에 대한 상세한 설명은 생략하였음을 미리 밝혀두는 바이다.
It is to be noted that like elements in the accompanying drawings use the same reference numerals in any of the drawings, and detailed descriptions of well-known functions or known configurations that may unnecessarily obscure the gist of the present invention are omitted. Come on.

첨부도면에서 도시한 바와 같이 볼트(1)와 너트(2)는 서로 나사 결합하되, 볼트(1)의 몸통부(102)가 소켓(3)을 관통하도록 볼트(1)와 너트(2) 사이에 소켓(3)을 개입 설치하게 된다.The bolt 1 and the nut 2 are screwed to each other so that the body portion 102 of the bolt 1 passes through the socket 3 between the bolt 1 and the nut 2, So that the socket 3 can be installed.

이때, 너트(2)의 외경은 소켓(3)의 내경보다 크기 때문에 볼트(1)와 너트(2)의 결합력에 의해 소켓(3) 내부로 삽입되는 너트(2)의 외경에 의해 너트(2)가 삽입되는 소켓(3)의 일단부는 확개된다
Since the outer diameter of the nut 2 is larger than the inner diameter of the socket 3, the nut 2 is inserted into the socket 3 by the coupling force between the bolt 1 and the nut 2, The one end of the socket 3 into which the plug 3 is inserted is expanded

즉, 소켓(3)의 일단부에는 길이 방향으로 적어도 두 개 이상의 제1절개부(301)를 형성하여 제1절개부(301) 사이에 제1확개편(302)을 형성함으로써 첨부도면 도 3과 같이 앵커설치공(4)에 소켓(3)이 투입되도록 본 발명을 설치한 후, 피고정물(5)을 결합한 상태에서 너트(2)와 결합된 볼트(1)를 조이게 되면, 볼트(1)와 너트(2)의 결합력에 의해 너트(2)가 소켓(3)의 일단부로 삽입되면서 제1확개편(302)이 확개되어 앵커설치공(4)의 내주면에 강하게 밀착되면서 견고한 고정력을 발생하게 되는 것이다.
That is, at least one first cutout 301 is formed in the longitudinal direction at one end of the socket 3 to form the first cutout 302 between the first cutouts 301, When the bolts 1 engaged with the nuts 2 are fastened with the fixture 5 engaged after the present invention is installed so that the sockets 3 are inserted into the anchor mounting holes 4, The nut 2 is inserted into the one end of the socket 3 by the coupling force of the nut 2 and the first deformation piece 302 is expanded and tightly attached to the inner circumferential surface of the anchor mounting hole 4 to generate a firm fixing force It will be done.

한편, 볼트(1)와 너트(2)를 결합한 후 볼트(1)를 회전시키는 과정에서 소켓(3) 하단부에서 소켓(3) 내부로 삽입되면서 소켓(3)의 제1확개편(302)를 확개시키는 너트(2)의 외주면에는 상단부가 테이퍼진 경사돌편(201)을 방사형으로 형성하여, 그 경사돌편(201)이 소켓(3)의 제1절개부(301)로 투입되면서 볼트(1)와 너트(2)가 결합되도록 함으로써 제1확개편(302)의 확개를 위하여 볼트(1)를 조이는 과정에서 너트(2)가 볼트(1)와 함께 회전하는 것을 방지하여 제1확개편(302)의 확개가 원활히 이루어질 수 있게 된다.
After the bolts 1 and the nuts 2 are coupled with each other, the bolts 1 are inserted into the socket 3 from the lower end of the socket 3 while rotating the bolts 1, A slanting protrusion 201 having a tapered upper end is radially formed on an outer circumferential surface of the nut 2 to be widened so that the inclined protrusion 201 is inserted into the first cutout 301 of the socket 3, The nut 2 is prevented from rotating together with the bolt 1 in the course of tightening the bolt 1 for the purpose of widening the first deeper part 302 and the first deeper part 302 ) Can be smoothly performed.

아울러, 소켓(3)에 형성된 제1절개부(301)의 상단부에서 양측으로 분할되어 상향으로 제2절개부(303)를 형성하여 제2절개부(303) 사이에 제2확개편(304)을 형성함으로써 볼트(1)와 너트(2)의 결합에 의해 제1확개편(302)이 좌우로 확개된 상태에서도 볼트(1)를 계속 조이면 볼트(1)와 나사 결합된 너트(2)가 계속 상승함으로써 소켓(3)의 내경보다 큰 외경을 가진 너트(2)에 의해 제2확개편(304)도 확개되면서 앵커설치공(4)의 내주면에 밀착되어 더욱 견고한 고정력이 발생하게 된다.
The second cut 303 is divided into two portions at the upper end of the first cutout 301 formed in the socket 3 so that the second cutout 303 is formed between the second cutout 303 and the second cutout 304, The nut 2 that is threadedly engaged with the bolt 1 when the bolt 1 is continuously tightened even in the state where the first re-sculpted piece 302 is widened to the left and right by the engagement of the bolt 1 and the nut 2 The second expanded piece 304 is also expanded by the nut 2 having an outer diameter larger than the inner diameter of the socket 3 so as to be brought into close contact with the inner peripheral surface of the anchor mounting hole 4 to generate a more rigid fixing force.

또한, 제1확개편(302)과 제2확개편(304)은 평면에서 볼 때 방사형으로 형성함으로써 앵커설치공(4) 내부에 삽입 설치되는 소켓(4)이 방사형으로 고정력을 발생시키기 때문에 앵커설치공(4) 내주면이 매끄럽지 못하고, 손상된 상태에서도 더욱 견고한 고정력을 발생시킬 수 있게 되는 것이다.
The first deformation piece 302 and the second deformation piece 304 are formed in a radial shape when seen from the plane, so that the socket 4 inserted in the anchor mounting hole 4 generates a fixing force radially, The inner circumferential surface of the mounting hole 4 is not smooth, and a firm fixing force can be generated even in a damaged condition.

한편, 첨부도면 도 4는 본 발명의 또 다른 실시 예를 나타낸 것으로서, 도면에서 도시한 바와 같이 앵커설치공(4) 내부에 삽입되는 볼트(1a)의 머리부에 경사돌편(102)을 형성하여 볼트(1a)의 머리부를 앵커설치공(4) 내부로 투입한 상태로 본 발명을 설치한 후, 피고정물(5)을 결합한 상태에서 볼트(1a)와 결합된 볼트(2a)를 조이게 되면, 볼트(1a)와 너트(2a)의 결합력에 의해 볼트(1a)의 머리부가 소켓(3)의 일단부로 삽입되면서 제1확개편(302)과 제2확개편(304)를 확개시킴으로써 견고한 고정력이 발생하게 된다.
4 shows another embodiment of the present invention. As shown in the figure, the inclined protrusion 102 is formed on the head of the bolt 1a inserted into the anchor mounting hole 4 If the bolt 2a engaged with the bolt 1a is fastened while the head of the bolt 1a is inserted into the anchor mounting hole 4 and the fixture 5 is engaged after the present invention is installed, The first reshaped piece 302 and the second reshaped piece 304 are expanded by inserting the head of the bolt 1a into the one end of the socket 3 by the force of the bolt 1a and the nut 2a, .

아울러, 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시나 응용이 가능한 것은 물론이고, 이러한 변형 실시나 응용 예는 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해돼서는 안 될 것이다.
