Abstract

The present invention provides a deployment-type sleeve, an anchor bolt, and a set anchor, wherein the deployment-type sleeve is formed to have, without using a pipe-shaped tool, concavo-convex protrusions formed on the inner wall and surrounding the anchor bolt so as to be deployed toward a concrete structure by a pressing head of the anchor bolt and is embedded and fixed in the side surface of an installation hole of the concrete structure due to the external force or nut fastening. The deployment-type sleeve includes an inner wall and an outer wall having the length and the outer diameter corresponding to the depth and the diameter of the installation hole perforated in the concrete structure. The concavo-convex protrusions are formed on the inner wall in the lengthwise direction of the anchor bolt and surround the anchor bolt, and thus, the deployment-type sleeve is deployed toward the concrete structure due to the pressing head of the anchor bolt and then is embedded and fixed in the side surface of the installation hole due to the external force or the nut fastening.

Description

전개형 슬리브, 앵커 볼트, 및 세트 앵커Deployable Sleeves, Anchor Bolts, and Set Anchors
본 발명은 앵커에 관한 것으로, 보다 상세하게는 콘크리트 또는 철근 콘크리트에 고정물을 고정하기 위한 시공에 사용되는 전개형 슬리브, 앵커 볼트, 및 세트 앵커에 관한 것이다.The present invention relates to anchors, and more particularly to deployable sleeves, anchor bolts, and set anchors used in construction for fixing fixtures to concrete or reinforced concrete.
일반적으로, 세트 앵커는 볼트, 파이프, 평와셔, 스프링 와셔 및 너트를 포함하여 구성된다.Generally, set anchors include bolts, pipes, flat washers, spring washers and nuts.
상기한, 세트 앵커는 벽이나 바닥에 구멍을 뚫은 후 볼트가 체결된 파이프를 구멍에 삽입하고 펀치로 파이프를 타격하여 시공하고, 파이프의 단부가 타격에 의해 구멍 내에서 벌어지면서 내진성(견디는 힘)을 갖는다.The set anchor described above is constructed by drilling a hole in a wall or floor, inserting a pipe fastened with a bolt into the hole, and hitting the pipe with a punch. have
이때, 볼트는 고정물의 두께를 고려하여 벽이나 바닥에서 일정 길이 노출되도록 시공된다.At this time, the bolt is constructed to be exposed to a certain length from the wall or floor in consideration of the thickness of the fixture.
그 후, 고정물이 자신의 관통공을 노출된 볼트가 관통하도록 배치되고, 너트가 볼트의 단부에 결합됨으로써 세트 앵커의 시공이 완료된다.Thereafter, the fixture is disposed so that the exposed bolt passes through its through hole, and the nut is coupled to the end of the bolt, thereby completing the construction of the set anchor.
일반적으로, 시공 현장에서 세트 앵커는 하나의 고정물을 설치하기 위하여 다수의 위치에 사용되는 것이 일반적이다. 그러므로, 세트 앵커는 벽이나 바닥에 노출된 볼트의 길이가 일정하도록 시공되어야 한다.In general, in a construction site, set anchors are generally used in multiple locations to install one fixture. Therefore, set anchors must be constructed so that the length of bolts exposed to the wall or floor is consistent.
그러나, 종래의 세트 앵커는 고정물의 두께를 고려하여 볼트의 노출된 길이가 균일하도록 시공하는 것이 어렵다. 그러므로, 종래의 세트 앵커는 시공성이 떨어지고 정교한 시공에 한계가 있다.However, it is difficult to construct the conventional set anchor so that the exposed length of the bolt is uniform in consideration of the thickness of the fixture. Therefore, conventional set anchors are poor in workability and have limitations in sophisticated construction.
또한, 종래의 세트 앵커는 노출된 볼트의 길이가 불균일함에 따라 고정물을 고정한 후 고정물 상에 위치 별로 남는 모양이 달라진다. 그러므로, 시공 후 노출되는 미감이 떨어진다.In addition, the conventional set anchor has a different shape remaining on the fixture for each position after fixing the fixture as the length of the exposed bolt is non-uniform. Therefore, the aesthetic sense exposed after construction is inferior.
그리고, 종래의 세트 앵커는 진동 등의 이유로 구멍이 넓어져서 체결 상태가 이완된 경우 재시공해야하는 어려움이 있다.In addition, the conventional set anchor has difficulty in re-construction when the hole is widened due to vibration or the like and the fastening state is relaxed.
그리고, 종래의 세트 앵커는 파이프가 벌어지면서 구멍의 하부와 결합되는 구조를 갖는다. 그러므로, 이와 같이 종래의 세트 앵커는 파이프의 벌어짐만 의존하는 내진성을 제공함으로써 고정물에 대한 충분한 내진성을 제공하는데 한계가 있다.And, the conventional set anchor has a structure in which the pipe is coupled to the lower part of the hole while being widened. Therefore, since the conventional set anchor provides seismic resistance that depends only on the opening of the pipe, there is a limit to providing sufficient seismic resistance to the fixture.
이와 같은 종래의 앵커세트는 도 8에 도시된 바와 같이 나사부를 가진 가지며 단부부위에 확장되는 테이퍼부가 형성된 볼트봉(110)과, 상기 볼트봉(110)에 끼워져 타격시에 상기 볼트봉(110)의 단부에 확장된 페이퍼부에 의해 그 지름이 확장 가능하도록 몸체 일부에 절개부(121)가 형성된 쐐기관(120)으로 구성되어 있다.As shown in FIG. 8, such a conventional anchor set includes a bolt rod 110 having a threaded portion and having a tapered portion extending at an end portion, and a bolt rod 110 inserted into the bolt rod 110 and hitting the bolt rod 110 It is composed of a wedge pipe 120 having an incision 121 formed in a part of the body so that its diameter can be expanded by the expanded paper portion at the end of the pipe.
이때, 앵커세트의 시공방법은 다음과 같다.At this time, the construction method of the anchor set is as follows.
먼저, 볼트봉(110)을 쐐기관(120)에 삽입하고, 쐐기관(120)에 삽입된 볼트봉(110)을 앵커공에 삽입한다. 볼트봉(110) 삽입후에는 파이프 형태로 된 공구를 이용하여 쐐기관(120)의 외측단부에 접하도록 한 다음, 공구를 타격한다. 이렇게 되면, 쐐기관(120)이 내측으로 삽입되면서 볼트봉(110)의 테이퍼부에 의해 쐐기관(120)의 절개부가 절개되면서 지름이 확장되게 되며, 확장된 쐐기관(120)이 앵커공에 고정되게 되며 이에 따라 볼트봉(110) 또한 쇄기관(120)과 함께 앵커공에 고정되게 되는 것이다.First, the bolt rod 110 is inserted into the wedge pipe 120, and the bolt rod 110 inserted into the wedge pipe 120 is inserted into the anchor hole. After the bolt bar 110 is inserted, a tool in the form of a pipe is used to contact the outer end of the wedge pipe 120, and then the tool is struck. In this case, while the wedge pipe 120 is inserted into the inside, the incision of the wedge pipe 120 is incised by the tapered portion of the bolt rod 110 and the diameter is expanded, and the expanded wedge pipe 120 is attached to the anchor hole. It is fixed, and accordingly, the bolt rod 110 is also fixed to the anchor ball together with the chain pipe 120.
이와 같은 작업으로 볼트봉(110)이 구조물에 고정되게 되면 볼트봉(110)의 나사부에 브라켓 등을 고정하여 각종 피착물을 고정하게 된다.When the bolt rod 110 is fixed to the structure by this operation, a bracket or the like is fixed to the threaded portion of the bolt rod 110 to fix various adherends.
상기와 같은 앵커세트를 구조물에 고정할 때 파이프 형태로 된 공구를 이용하여 쐐기관(120)의 외측단부에 접하도록 한 다음 공구를 타격하여 쐐기관(120)의 내측단부가 볼트봉(110)의 테이퍼부에 의해 벌려져 앵커공에 고정되기는 하지만, 쐐기관(120)의 내측단부가 앵커공에 고정되므로 고정력이 약하며, 별도 파이프 형태 공구를 이용하여야 하는 번거러움이 있다.When fixing the anchor set as described above to the structure, use a tool in the form of a pipe to bring it into contact with the outer end of the wedge pipe 120, and then hit the tool so that the inner end of the wedge pipe 120 is bolt rod 110 Although it is fixed to the anchor ball by being widened by the tapered part of the pipe, since the inner end of the wedge pipe 120 is fixed to the anchor ball, the fixing force is weak, and there is a hassle of using a separate pipe-shaped tool.

본 발명은 파이프 형태의 공구를 이용할 필요없이 내벽에 요철 돌기가 앵커 볼트를 감싸도록 형성되어 앵커 볼트의 가압 헤드에 의해 콘크리트 구조물 쪽으로 전개되며, 외력 또는 너트 조임에 의해 콘크리트 구조물의 설치공의 측면에 파고들어 고정되는 전개형 슬리브를 제공하는데 그 목적이 있다.In the present invention, concavo-convex protrusions are formed on the inner wall to surround anchor bolts without the need to use pipe-type tools, and are deployed toward the concrete structure by the pressing head of the anchor bolts, and by external force or nut tightening, on the side of the installation hole of the concrete structure. Its purpose is to provide a deployable sleeve that is dug in and fixed.
