Description
본 고안은 몰탈을 사용하지 아니하고 블록 벽체를 축조하므로서 시공성을 증대할 수 있는 건축용 중공(中空) 블록(Block) 및 그를 이용한 블록 벽체구조에 관한 것이다.The present invention relates to a building hollow block and a block wall structure using the same, which can increase workability by constructing a block wall without using mortar.
일반적으로 중공 블록은 전후면이 편평하게 형성되고, 그 상하면에는 중공부가 형성되어 있으며, 그 양 측면에는 반원형 홈이 형성되어 있다. 이러한 블록으로 블록 벽체를 축조할 할 경우에, 상하 좌우 블록 사이에 반드시 몰탈을 사용하여 축조하게 된다. 그리고 필요에 따라 중공부 속으로 철근을 삽입하여 벽체를 보강하게 되는 것이다.In general, the hollow block has a flat front and rear surface, a hollow portion is formed on the upper and lower surfaces thereof, and semicircular grooves are formed on both sides thereof. When the block wall is constructed by such a block, mortar is always used between the upper, lower, left, and right blocks. And reinforcing the wall by inserting reinforcing bars into the hollow as needed.
이와 같이 시공되는 종래의 블록은 몰탈을 사용하여 축조하므로서, 공사에 많은 제약을 받게 되는 문제가 있다. 즉, 몰탈은 어느 정도 경화되는 시간이 필요하므로 벽체를 어느 정도 쌓은 후, 몰탈이 경화될 때까지 기다려야 하므로 벽체를 하루 3단 내지 4단 이상을 쌓을 수 없다. 또한, 몰탈에는 수분이 함유되어 있으므로 추운 겨울철에는 몰탈이 얼 수 있기 때문에 공사를 진행할 수 없다. 더욱이 몰탈을 사용하게 되면 모래, 시멘트, 물 등의 재료를 현장으로 반입하고 혼합하는 불편이 수반될 뿐만 아니라, 블록 벽체를 쌓는 블록 기능공 등이 필요하므로 여러면에서 시공성이 떨어지는 문제가 있다.The conventional block constructed as described above has a problem of being constrained by the construction by using mortar. That is, since mortar needs a certain amount of time to harden, after stacking the wall to some extent, it is necessary to wait until the mortar hardens, so that the wall cannot be stacked three to four times a day. In addition, since the mortar contains water, construction cannot proceed because the mortar may freeze in the cold winter. Moreover, the use of mortar not only entails the inconvenience of bringing and mixing materials such as sand, cement, and water into the field, but also requires a block functional worker to stack the block walls, which causes problems in construction.
본 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 몰탈을 전혀 사용하지 않고 블록 벽체를 시공할 수 있으며, 특별한 기술이 없는 사람도 손쉽게 시공할 수 있는 건축용 중공 블록 및 그를 이용한 블록 벽체구조를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, it is possible to construct a block wall without using mortar at all, to provide a building hollow block and a block wall structure using the same that can be easily constructed even without a special technology. The purpose is.

본 고안에 따른 건축용 중공블록은 도면에서와 같이, 가운데 중공부(12)를 형성하고 양 측면에 반원형 홈을 형성하는 건축용 중공블록에 있어서, 블록 몸체부(11)의 상면에 돌부(13)를 형성하고, 블록 몸체부(11)의 하면에는 상기 돌부(13)의 형상이 결합될 수 있도록 홈부(14)를 형성하되, 상기 돌부(13) 및 홈부(14)를 상기 중공부(12)의 전후측 연장선상(L1)(L2) 내에 형성하는 것을 특징으로 한다.Building hollow block according to the present invention, as shown in the figure, in the building hollow block to form a hollow portion 12 and the semi-circular grooves on both sides, the protrusion 13 on the upper surface of the block body portion 11 And a groove 14 is formed on the bottom surface of the block body 11 so that the shape of the protrusion 13 may be coupled, and the protrusion 13 and the groove 14 may be formed in the hollow portion 12. It is formed in front-back side extension line L1 (L2), It is characterized by the above-mentioned.
여기서, 돌부(13)와 홈부(14)는 중공부(12)의 좌우측에 각각 하나씩 형성하고 있으나, 그 갯수는 블록의 형상에 따라 달라질 수 있으며, 그 형태나 모양도 달라질 수 있다. 또한, 돌부(13)와 홈부(14)는 중공부(12)의 전후측 연장선상(L1)(L2) 내에 형성하므로써 전단력을 증대시킬 수 있다(도3참조).Here, the protrusions 13 and the grooves 14 are each formed on the left and right sides of the hollow portion 12, but the number may vary depending on the shape of the block, the shape or shape may also vary. Further, the protrusions 13 and the grooves 14 can be formed in the front and rear extension lines L1 and L2 of the hollow portion 12 to increase the shear force (see Fig. 3).
상기 돌부(13)에는 블록 몸체부(11)의 길이방향으로 수평 보강재(40')를 배치할 수 있도록 배근홈(13a)을 형성하고 있다(도5참조). 또한, 상기 중공부(12)는 결속 핀(Pin)(30)을 용이하게 결속할 수 있도록 상부가 넓고 하부는 좁게 형성되는 것이 바람직하다(도5참조).The protrusion 13 is formed with a reinforcement groove 13a to arrange the horizontal reinforcement 40 'in the longitudinal direction of the block body portion 11 (see FIG. 5). In addition, the hollow portion 12 is preferably formed in the upper portion is wider and the lower portion is narrow so as to easily bind the binding pin (Pin 30) (see Fig. 5).
한편, 도면에 도시하지는 않았으나, 중공 블록(10)의 상면에 후방쪽으로 철근 결속용 홈을 형성할 수도 있다. 철근 결속용 홈은 중공부(12)에서 시작하여 중공 블록(10)의 배면까지 형성된다. 이는 블록 벽체 시공시 결속용 철근을 중공 블록(10)에 결속시켜 블록 벽체의 후방으로 연장시켜 지반 등에 지지할 수 있도록 하기 위함이다. 이 때 결속용 철근은 중공부(12)에 결속되는 결속 핀(30)에 결속할 수도 있다. 또한, 본 중공 블록(10)은 양 측면을 전측 또는 후측 방향으로 경사지게 형성할 수 있다. 이는 블록 벽체 시공시 블록 벽체의 코너(Corner) 구간 또는 곡선 구간을 유용하게 축조하기 위한 것이다.On the other hand, although not shown in the drawings, the groove for the reinforcing bar may be formed on the upper surface of the hollow block 10 toward the rear. Reinforcing bar grooves are formed starting from the hollow portion 12 to the rear surface of the hollow block 10. This is to bind the reinforcing bars to the hollow block 10 during construction of the block wall to extend to the rear of the block wall to support the ground and the like. At this time, the binding reinforcing bar may be bound to the binding pin 30 that is bound to the hollow portion 12. In addition, the present hollow block 10 may be formed to be inclined both sides in the front or rear direction. This is to usefully construct a corner section or a curved section of the block wall when constructing the block wall.
도4 내지 도7은 상기한 블록을 사용하여 블록 벽체를 시공한 예를 보여주는 것이다. 블록 벽체구조는 중공 블록(10)들의 각 상면과 하면에 형성된 돌부(13)와 홈부(14)를 서로 결합하여 적층한 블록 벽체(20)와, 상기 중공 블록(10)의 중공부(12)에 삽입하여 상하 적층되는 중공 블록(10)들을 서로 결속하는 결속핀(30)과, 상기 결속 핀(30)에 수직 및 수평 방향으로 각각 형성된 수직공(31) 및 수평공(32)을 통하여 상기 블록 벽체(20)를 보강하는 수직 보강재(40) 및 수평 보강재(40')를 포함하고 있다.4 to 7 show an example in which a block wall is constructed using the above-described block. The block wall structure includes a block wall 20 in which the protrusions 13 and the grooves 14 formed on the upper and lower surfaces of the hollow blocks 10 are laminated to each other, and the hollow part 12 of the hollow block 10. Inserting through the binding pins 30 to bind the hollow blocks 10 stacked up and down with each other, and through the vertical hole 31 and the horizontal hole 32 formed in the vertical and horizontal directions to the binding pin 30, respectively The vertical reinforcement 40 and the horizontal reinforcement 40 'which reinforce the block wall 20 are included.
즉, 본 고안의 블록 벽체구조는 상하 중공 블록(10)들 간에는 돌부(13)와 홈부(14)로 결합함과 동시에, 중공부(12)를 통하여 결속 핀(30)으로 결속하고 있다. 이 때 결속 핀(30)에 형성된 수직공(31) 및 수평공(32)을 통하여 수직 보강재(40)와 수평 보강재(40')를 보강하고 있다.That is, the block wall structure of the present invention is coupled to the protrusion 13 and the groove 14 between the upper and lower hollow blocks 10, and is bound by the binding pin 30 through the hollow 12. At this time, the vertical reinforcing material 40 and the horizontal reinforcing material 40 'are reinforced through the vertical hole 31 and the horizontal hole 32 formed in the binding pin 30.
블록 벽체(20)는 상하 중공 블록(10)들이 서로 어긋나게 적층되므로, 하부의 중공 블록 좌우측에 각각 상부의 중공 블록이 1개씩 적층된다. 이 때 상하 중공 블록(10)들의 돌부(13)와 홈부(14)가 서로 맞게 결합되도록 중공 블록(10)을 형성하는 것이 필요하다. 또한, 결속 핀(30)의 하부는, 하부에 설치되는 중공 블록(10)의 중공부(12)에 결속되고, 그 결속 핀(30)의 상부는, 상부에 설치되는 2개의 좌우측 중공 블록(10) 사이, 즉 블록의 측면에 형성된 반원형 홈이 합쳐져서 이루어진 중공부(12a)에 결속된다(도5참조).In the block wall 20, the upper and lower hollow blocks 10 are stacked to be offset from each other, and thus, the upper hollow blocks are stacked one by one on the left and right sides of the lower hollow blocks. At this time, it is necessary to form the hollow block 10 so that the protrusions 13 and the grooves 14 of the upper and lower hollow blocks 10 fit together. In addition, the lower part of the binding pin 30 is bound to the hollow part 12 of the hollow block 10 provided in the lower part, and the upper part of the binding pin 30 is provided with two left and right hollow blocks ( 10), that is, the semicircular grooves formed on the side of the block are bound to the hollow portion 12a formed by joining (see Fig. 5).
결속 핀(30)은 중공부(12)의 형상에 따라 그 형태와 모양이 바뀔 수 있다. 본 실시예에서는 상하부가 작고 가운데가 크게 형성된 오뚜기 형상으로 되어 있으며, 수직공(31)과 수평공(32)은 서로 엇갈리게 형성하고 있다.(도7참조). 수평 보강재(40')는 중공 블록(10)의 돌부(13)에 형성된 배근홈(13a)을 통과하면서 배치된다.The binding pin 30 may be changed in shape and shape according to the shape of the hollow part 12. In the present embodiment, the upper and lower portions have a small pentagonal shape with a large center, and the vertical holes 31 and the horizontal holes 32 are alternately formed (see Fig. 7). The horizontal reinforcement 40 'is disposed while passing through the reinforcement groove 13a formed in the protrusion 13 of the hollow block 10.
이상에서 설명한 바와 같이 본 고안에 의하면, 중공 블록의 상하면에 각각 형성된 돌부와 홈부를 결합하여 축조하며, 상하 블록을 결속 핀으로 결속함과 동시에 결속 핀에 형성된 수직공 및 수평공을 통하여 수직 보강재 및 수평 보강재를 보강하므로써, 몰탈을 사용하지 않고도 시공이 가능할 뿐만 아니라, 블록 기능공이 아닌 사람도 손쉽게 시공할 수 있는 효과를 갖는다.As described above, according to the present invention, the protrusions and the grooves respectively formed on the upper and lower surfaces of the hollow block are combined and constructed, and the upper and lower blocks are bound with the binding pins, and at the same time, the vertical reinforcement member is formed through the vertical and horizontal holes formed in the binding pins. By reinforcing the horizontal reinforcing material, not only can be installed without using mortar, but also has an effect that can be easily installed by non-block technicians.
