본 발명과 관련된 종래기술로는 본 출원인의 특허 제0632966호의 옹벽 축조용 코너 블록이 개시되어 있는데, 이는 좌우로 인접하는 블록 사이에 상호 요철결합이 이루어지도록 좌우 측면을 갖는 일반 블록만을 사용하여 옹벽을 축조할 때 코너부에서 지반의 부등침하 또는 보강토체의 수평변위 발생시 엇쌓기식으로 축조된 블록에 전단력이 집중되어 파손이 발생하거나 블록간 틈새가 크게 벌어지는 현상을 방지함과 아울러 최소한의 공간에서 직각으로 코너부를 축조할 수 있도록 함으로써 공간활용도를 높이고 소요자재의 절감을 도모할 수 있도록 하기 위한 것으로, 이는 도 1에 도시된 바와 같이 코너 블록(A) 좌우의 측면에는 각각 직각으로 축조되는 블록(B)의 측부가 각각 끼워지는 수용홈(12)이 상호 직각이 되게 형성되고, 상면에는 후방으로 보강재 또는 앵커의 선단부가 끼워지는 보강재 삽입홈이 형성되며, 이 보강재 삽입홈에는 상하로 축조되는 블록간의 결합을 위한 연결핀이 끼워지는 연결핀 삽입구멍이 형성된 구조로 이루어져 있다.The related art of the present invention discloses a retaining wall construction corner block of the applicant's patent No. 0632966, which uses only a general block having left and right sides so that mutual concavities and convexities are formed between adjacent blocks from side to side. In case of construction, in case of uneven settlement of ground or horizontal displacement of reinforcement soil at the corner, shear force is concentrated on the stacked blocks to prevent breakage or large gaps between blocks, and at the right angle in the minimum space. In order to increase the space utilization and to reduce the required materials by allowing the corner portion to be constructed, this is a block (B) which is constructed at right angles to the left and right sides of the corner block (A), as shown in FIG. 1. Receiving grooves 12 to which the sides of the) are fitted so as to be perpendicular to each other, the reinforcement to the rear on the upper surface Alternatively, a reinforcing member insertion groove is formed in which the tip portion of the anchor is fitted, and the reinforcing member insertion groove has a structure in which a connection pin insertion hole is formed in which a connection pin for fitting between blocks constructed up and down is inserted.
상술한 특허 제0632966호의 코너 블록은 옹벽 선형 중 직각으로 돌출되는 부위에만 적용이 가능한 문제가 있었으며, 직각으로 만입되는 부위에 있어서는 도 2에 도시된 바와 같이 코너 블록(A)은 사용하지 못하고, 대신 일반 블록(B)과 반블록(C)만을 조합하여 축조하였기 때문에 코너부가 직각을 이루지 못하고 대각선으로 형성되는 문제점이 있었을 뿐만 아니라 일반 블록(B)과 반블록(C)간의 결합력도 떨어져 블록 사이의 틈새가 벌어지는 등의 하자가 빈번하게 발생하는 문제점이 있었고, 기타 다양한 각도의 선형으로 이루어지는 옹벽 부위에서는 사용할 수 없다는 한계가 있었다.The above-described corner block of Patent No. 0632966 has a problem that can be applied only to a portion projecting at right angles in the retaining wall linear, and the corner block A is not used as shown in FIG. Since only the general block (B) and the half block (C) are constructed, the corners are not formed at right angles and are formed diagonally, and the coupling force between the general block (B) and the half block (C) is also lowered. There was a problem that defects such as gaps occur frequently, and there is a limit that can not be used in the retaining wall portion formed of a linear of various angles.
또, 도 1 및 도 2에 도시된 코너 블록을 사용하여 코너 옹벽을 축조할 경우에는 별도의 반블록(C)을 추가로 사용하여야 했었으므로 재료의 추가 구입에 따른 원가상승의 요인이 되기도 하였고, 반 블록은 인접하는 블록 및 보강토체와의 결합력이 떨어져 이 부분이 쉽게 빠져나오거나 간격이 벌어져 토사가 유출되는 원인이 되기도 하였다.In addition, when constructing the corner retaining wall using the corner blocks shown in FIGS. 1 and 2, an additional half block (C) had to be additionally used, which may cause a cost increase due to additional purchase of materials. The half block has a weak coupling force between adjacent blocks and reinforcement soils, and this part easily escapes or opens a gap, causing soil leakage.
한편, 본 출원인의 선등록실용신안 제0412264호의 보강토 옹벽 축조용 블록은 상기한 문제점을 해결할 수 있도록 좌,우로 인접하는 블록 간에는 직선 또는 다양한 곡선 형태로 결합될 수 있도록 하여 지형에 따른 선형을 갖는 옹벽을 축조할 수 있도록 하였는데, 이는 도 3 내지 도 5에 도시된 바와 같이 옹벽 면을 형성하는 전면과 이 전면에 대응되는 후면, 좌·우 측면 및 상·하면을 가지며, 내부에는 상·하로 관통공이 형성된 옹벽 축조용 블록에 있어서; 상기 상면의 후부 양측에는 상·하로 적층되는 블록 간의 인터록킹을 위한 결합돌기(52,54)가 돌출형성되고, 이 결합돌기(52,54)의 전방과 내측부 후방으로는 보강재 삽입홈이 형성되며, 상기 하면의 후부 양측에는 상기 결합돌기(52,54)가 끼워지도록 끼움홈(62,64)이 형성된 구조로 이루어져 있다.On the other hand, the reinforcement soil retaining wall construction block of the applicant's prior application model No. 0412264 can be combined between the left and right adjacent blocks in a straight line or various curved forms so as to solve the above problems, the retaining wall having a linear according to the terrain 3 to 5, which has a front surface forming a retaining wall surface and a rear surface corresponding to the front surface, a left side, a right side surface, and a top surface and a bottom surface. In the retaining wall construction block formed; Coupling protrusions 52 and 54 for interlocking between blocks stacked up and down are formed on both sides of the rear portion of the upper surface, and reinforcement insert grooves are formed at the front and the inner side of the coupling protrusions 52 and 54, respectively. On both sides of the rear surface of the lower surface, fitting grooves 52 and 54 are formed to have fitting grooves 62 and 64 formed therein.
상기한 실용신안등록 제0412264호는 다양한 선형의 옹벽을 축조하는 데는 적합하나, 직각으로 돌출되거나 직각으로 만입된 코너 옹벽의 축조시에는 도 5에 도시된 바와 같이 곡률반경이 커지게 되고, 소요자재의 낭비를 초래하게 되는 단점이 있었다.The above-mentioned Utility Model Registration No. 0412264 is suitable for constructing various linear retaining walls, but when constructing corner retaining walls protruding at right angles or indented at right angles, the radius of curvature increases as shown in FIG. There was a disadvantage that causes wasted.
또, 도 6 및 도 7에 도시된 종래의 일반 블록(B)으로 곡선형의 옹벽을 축조할 경우에는 옹벽 전면에 상,하 블록 사이의 단차(돌출 및 만입부)가 발생하여 미관상 보기에 좋지 않을 뿐만 아니라 상,하 블록 간의 접지면적이 작아져 부등침하에 따른 전단응력을 받을 경우 옹벽의 선형이 뒤틀리게 되거나 응력이 집중된 블록이 쉽게 파손될 우려가 있었다.In addition, when constructing a curved retaining wall with the conventional general block (B) shown in Figs. 6 and 7, a step (protrusion and indentation) between the upper and lower blocks occurs on the front of the retaining wall, which is good for aesthetic appearance. Not only that, the ground area between the upper and lower blocks is small, so that the linear stress of the retaining wall may be distorted or the stress concentrated block may be easily damaged when the shear stress is caused by the differential settlement.
또한, 기존의 블록으로 곡선부 옹벽을 축조할 경우에는 블록 상하면이 맞닿은 상태에서 축조됨으로써 부등침하 및 방사상으로 작용하는 보강토체의 수평변위(토압)에 의해 곡선부의 블록이 파손되는 현상이 빈번하였다.In addition, when the curved retaining wall is constructed by the existing block, the curved block is frequently damaged by the horizontal displacement (earth pressure) of the reinforcing soil acting inevitably and radially because the upper and lower surfaces of the block are in contact with each other.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 직각으로 돌출되거나 만입된 직각 옹벽은 물론 좌우로 인접하는 블록 사이에 다양한 각도로 결합이 가능하도록 함으로써 지형에 어울리는 다양한 선형 즉, 직선형은 물론 다양한 곡률반경을 갖는 곡선형 옹벽을 경제적으로 축조할 수 있으면서도 구조적으로도 견고한 상태를 유지할 수 있는 옹벽 축조용 코너 블록 및 이 블록을 사용하여 옹벽의 코너부를 제공하는 데 있다.The present invention has been made to solve the above problems, the object of the present invention is to allow a variety of linear to match the terrain by allowing the coupling at various angles between the right and left right wall as well as the right angle retaining wall protruding at right angles. In addition, a retaining wall construction corner block capable of economically constructing a curved retaining wall having a straight line shape and various curvature radii while maintaining a structurally robust state, and using the block, provides a corner portion of the retaining wall.
상기한 목적을 달성하기 위하여 본 발명은 옹벽의 외면을 형성하는 전면, 보강토체에 접하는 후면, 좌우로 인접하는 블록 사이에 접촉하는 좌,우 측면 및 상하로 인접하는 블록 사이에 접촉하는 상,하면을 가지는 옹벽 축조용 블록에 있어서; 상기 좌,우 측면 중의 어느 일측은 측방으로 돌출된 하나의 결합부를 가지며, 타측은 상기 일측의 결합부가 임의의 각도로 결합가능하도록 상기 블록의 전면에서부터 후면에 이르기까지 동일 반경으로 복수의 결합부가 방사상으로 형성되어 좌,우로 인접하는 블록 사이의 각도를 조절해 줄 수 있도록 된 옹벽축조용 코너 블록을 제공한다.In order to achieve the above object, the present invention provides a top surface and a bottom surface contacting between left and right sides and top and bottom adjacent blocks contacting between the front and rear surfaces of the retaining wall, the rear surface contacting the reinforcement soil, and the adjacent blocks from side to side. In the retaining wall construction block having a; One side of the left and right sides has one coupling portion protruding to the side, the other side is a plurality of coupling portions radially from the front to the rear of the block from the front side of the block so that the coupling portion of the one side can be coupled at any angle It is formed to provide a retaining wall building corner block to adjust the angle between the adjacent blocks to the left, right.
본 발명에서 상기 방사상 결합부가 형성된 일 측면의 상부는 상면의 높이보다 낮게 단차를 형성하여 상하로 적층되는 블록 사이가 이격된 상태를 유지하도록 함으로써 전단력을 받더라도 응력집중에 의한 파손을 방지할 수 있도록 한다.In the present invention, the upper portion of one side of the radial coupling portion is formed to have a step lower than the height of the upper surface to maintain a spaced state between the blocks stacked up and down to prevent breakage due to stress concentration even under shear force. .
본 발명은 또, 소정의 각도로 이루어진 돌출형 코너부나 만입형 코너부의 옹벽을 축조하는 방법으로; 좌우로 인접하는 블록 사이에 상호 요철결합이 이루어지도록 좌우 측면을 갖는 일반 블록과 상기 코너 블록의 좌,우 측면을 상기 코너부의 좌우로 소정의 각도를 이루도록 맞대고 그 상부에는 다시 반대 방향으로 코너 블록과 일반 블록의 좌,우 측면을 소정의 각도를 이루도록 맞대서 축조하는 과정을 반복하는 것에 의해 코너부의 옹벽을 축조하는 방법을 제공한다.The present invention also relates to a method for constructing a retaining wall of a protruding corner portion or an indented corner portion formed at a predetermined angle; The general block having left and right sides and the left and right sides of the corner block are faced to form a predetermined angle to the left and right sides of the corner part so that mutual unevenness is formed between adjacent blocks from left and right, and the upper corner corner block Provided is a method for constructing a retaining wall of a corner by repeating a process of constructing the left and right sides of a general block in a predetermined angle to each other.
본 발명은 블록의 일 측면에 방사상으로 결합부가 형성되어 있으므로 인접하는 블록 사이의 연결각도를 돌출형 직각 코너부에서부터 만입형 직각 코너부까지 임의의 각도로 축조할 수 있으므로 최소한의 부지와 재료를 사용하여 지형에 적합하거나 토지소유주가 요구로 하는 옹벽을 축조할 수 있으며, 전단응력에도 강한 축조상태를 이룸으로써 시공하자가 발생할 우려도 적은 유용한 효과를 갖는다.In the present invention, since the coupling portion is formed radially on one side of the block, the connection angle between adjacent blocks can be constructed at any angle from the protruding right angle corner to the indented right angle corner. Therefore, it is possible to construct retaining walls that are suitable for the terrain or required by landowners, and by forming a strong construction state in shear stress, there is little risk of construction defects.

이하, 본 발명을 한정하지 않는 바람직한 실시 예들을 첨부된 도면에 의하여 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.
도 8은 본 발명의 제1실시 예에 의한 옹벽 축조용 코너 블록을 도시한 것으로, 2가지 타입의 코너 블록 2개가 함께 도시되어 있는데, 이는 좌,우 측면의 형태만이 뒤바뀐 타입이며, 이하의 설명에서는 좌,우 측면에 대하여 부호를 표기할 경우에는 편의상 도면에 도시된 상태의 좌,우측을 기준으로 설명하기로 한다.FIG. 8 illustrates a retaining wall building corner block according to a first embodiment of the present invention, and two types of corner blocks are shown together, which is a type in which only the left and right sides are inverted. In the description, when a reference numeral is written for left and right sides, it will be described with reference to the left and right sides of the state shown in the drawings for convenience.
도 8에 도시된 바와 같이 본 실시 예의 코너 블록(B)은 옹벽의 외면을 형성하는 전면(101), 보강토체에 접하는 후면(102), 좌우로 인접하는 블록 사이에 접촉하는 좌,우 측면(103,104) 및 상하로 인접하는 블록 사이에 접촉하는 상,하면(105,106)을 가지며, 상기 상면(105)에는 후면(102) 측으로 보강재가 연결되는 보강재 삽입홈(107)이 형성되고, 상,하 블록 간의 인터록킹을 위한 연결핀 삽입홈(108)이 형성되어 있으며; 상기 좌,우 측면(103,104) 중의 어느 일측은 측방으로 돌출된 하나의 결합부(104a)를 가지며, 타측은 상기 일측의 결합부(104a)가 임의의 각도로 결합가능하도록 상기 블록의 전면(101)에서부터 후면(102)에 이르기까지 동일 반경으로 복수의 결합부(103a)가 방사상으로 형성되어 좌,우로 인접하는 블록 사이의 각도를 임의의 각도로 조절하여 축조할 수 있도록 되어 있다.As shown in FIG. 8, the corner block B of the present embodiment has a front surface 101 forming an outer surface of the retaining wall, a rear surface 102 in contact with the reinforcement soil, and left and right side surfaces contacting between adjacent blocks left and right ( 103 and 104 and the upper and lower surfaces 105 and 106 in contact between the upper and lower adjacent blocks, the upper surface 105 is formed with a reinforcement insertion groove 107 is connected to the reinforcement toward the rear surface 102, upper and lower blocks Connecting pin insertion grooves 108 for interlocking therebetween are formed; One of the left and right sides 103 and 104 has one coupling portion 104a protruding laterally, and the other side of the block front side 101 is such that the coupling portion 104a of the one side can be coupled at an arbitrary angle. A plurality of engaging portions 103a are radially formed at the same radius from the back surface 102 to the rear surface 102 so that the angle between the adjacent blocks to the left and right sides can be adjusted to an arbitrary angle.
본 발명에서 상기 방사상의 결합부(103a)가 형성된 일 측면(103)의 상부는 상면(105)의 높이보다 낮게, 약 5mm내외의 단차를 이루도록 외력흡수홈(109)이 형성되어 있어 이 부분에서 상하로 적층되는 블록 사이가 밀착되지 않고 이격된 상태를 유지하도록 함으로써 부등침하에 의한 전단력을 받게 되더라도 응력집중에 의한 블록의 파손을 방지할 수 있도록 되어 있다.In the present invention, the upper portion of the side surface 103 formed with the radial coupling portion 103a is lower than the height of the upper surface 105, and the external force absorbing groove 109 is formed to form a step of about 5 mm. By maintaining the spaced apart state without close contact between the blocks stacked up and down, it is possible to prevent breakage of the block due to stress concentration even if the shear force is caused by the uneven settlement.
본 발명에서 상기 블록의 외형 즉, 블록에서 외형의 형태가 두드러지게 표현되는 전면(101)과 후면(102)의 형태는 특별히 제한하지 않으며 전면(101)은 도 8에 도시된 제1실시 예에서와 같은 직선형 스플릿타입으로 형성하거나 주름 또는 빗살무늬를 형성한 형태 등 다양한 형태로 성형할 수 있으며, 후면(102)의 형태 또한 도 8에 도시된 바와 같이 좌우측이 후방으로 돌출된 형태에 한정되지 않고 다양한 형태로 제작할 수 있음은 물론이다.In the present invention, the shape of the front face, that is, the shape of the front face 101 and the back face 102 in the block is not particularly limited and the front face 101 is the first embodiment shown in FIG. It can be formed in a variety of forms, such as the form of a straight split type, or the form of wrinkles or comb pattern, the shape of the back 102 is not limited to the shape in which the left and right sides protrude backward as shown in FIG. Of course, it can be produced in various forms.
도면 중 부호 110은 상,하면을 관통하는 관통공으로, 이 관통공(110)은 블록의 경량화 및 운반시의 편의를 위하여 설계된 사항이다.In the drawing, reference numeral 110 denotes a through hole penetrating the upper and lower surfaces, and the through hole 110 is a matter that is designed for light weight of the block and for convenience during transportation.
본 발명의 특징적인 구조인 블록의 좌,우 측면(103,104)의 형태는 위에서 설명한 바와 같이 좌,우 비대칭의 형태로 이루어져 있다는 점에 있는데, 이는 일 측면(104)의 결합부(104a)는 하나만 형성되어 있고, 타 측면(103)에는 블록(B)의 전면(101)에서부터 후면(102)까지 동일 반경으로 여러 개의 결합부(103a)가 형성된 점에 특징이 있다.The left and right sides 103 and 104 of the block, which is a characteristic structure of the present invention, are formed in the form of left and right asymmetry as described above, which means that only one coupling portion 104a of one side 104 is formed. The other side 103 is characterized in that a plurality of coupling portions 103a are formed at the same radius from the front surface 101 to the rear surface 102 of the block B.
상기 결합부(103a,104a)는 좌우로 인접하는 블록 사이의 측면이 맞닿으면서 블록 후방의 보강토체가 전면으로 노출되거나 유출되지 않도록 하기 위한 것으로, 일측의 결합부(104a)는 말 그대로 하나의 요부(104a-1)와 하나의 철부(104a-2)가 인접되게 형성되어 있고, 타측의 결합부(103a)는 마치 스퍼 기어와 같이 요부(103a-1)와 철부(103a-2)가 동심원을 이루면서 방사상으로 교대로 형성되어 있어 인접하는 블록의 결합부(104a)가 어느 위치의 결합부와 맞물리는가에 따라서 옹벽의 축조각도가 결정되도록 되어 있다.The coupling portions 103a and 104a are for preventing the reinforcement soils behind the blocks from being exposed or spilled to the front side while the side surfaces between adjacent blocks abut on the left and right sides, and the coupling portion 104a on one side is literally one main portion. 104a-1 and one convex portion 104a-2 are formed adjacent to each other, and the engaging portion 103a on the other side is concentric with the concave portion 103a-1 and the convex portion 103a-2 like a spur gear. In addition, they are radially formed alternately, and the axial angle of the retaining wall is determined depending on which position the engaging portion 104a of the adjacent block is engaged with.
이하에서는 상기한 실시 예의 블록과 일반 블록을 사용하여 축조되는 옹벽의 다양한 형태와 그 축조방법에 대하여 설명하기로 한다.Hereinafter, various forms of the retaining wall constructed using the block and the general block of the above-described embodiment and a method of constructing the same will be described.
도 9 및 도 10은 돌출형 직각 옹벽의 코너부를 도시한 것으로, 돌출형 직각 코너부에 좌우로 일반 블록(B1)과 코너 블록(B)의 좌,우 측면(103,104)을 직각이 되도록 맞대고 그 상부에는 다시 반대 방향으로 코너 블록(B)과 일반 블록(B1)의 좌,우 측면(103,104)을 직각이 되도록 맞대서 축조하는 과정을 반복하는 것에 의해 축조가 가능하게 되며, 보강토체의 내부로 매립되는 보강재는 코너 블록(B)을 기준으로 좌측의 옹벽과 우측의 옹벽에의 연결시 같은 위치에서 교차되지 않도록 블록 하나의 높이에 해당하는 단차를 두로 교대로 설치하는 것이 바람직하다.9 and 10 illustrate corner portions of the protruding rectangular retaining wall, and the left and right sides 103 and 104 of the general block B1 and the corner block B are arranged at right angles to the left and right corners of the protruding rectangular right wall. In the upper part again, the construction of the corner block B and the left and right side surfaces 103 and 104 of the general block B1 in the opposite direction is repeated, so that the construction can be performed by repeating the construction. The reinforcement to be embedded is preferably alternately provided with a step corresponding to the height of one block so as not to intersect at the same position when connecting the retaining wall on the left side and the retaining wall on the right side with respect to the corner block B.
본 발명에서는 보강재가 옹벽 전면에 대하여 직각을 이루도록 배치할 수 있으므로 보강토체의 침하나 기타 외력의 발생이 있더라도 보강재가 옹벽을 이루는 블록을 지지하는 힘이 균일하여 옹벽면의 변형이 발생하지 않는 장점이 있다.In the present invention, since the reinforcement may be disposed at right angles to the front surface of the retaining wall, even if there is sedimentation of the reinforcement body or other external force, the force supporting the block forming the retaining wall is uniform so that the deformation of the retaining wall does not occur. have.
한편, 코너부의 상,하 블록 사이는 외력흡수홈(109)에 의해 5mm정도 이격된 상태를 유지하며, 부등침하발생시 코너부에 응력이 집중하게 되어 코너블록에 전단력이 가해지는 것에 대하여 능동적으로 대비할 수 있다. 따라서 하자의 발생을 없앨 수 있다.On the other hand, between the upper and lower blocks of the corner portion is maintained by about 5mm spaced apart by the external force absorbing groove 109, the stress is concentrated in the corner portion when the differential settlement occurs to actively prepare for the shear force applied to the corner block Can be. Thus, the occurrence of defects can be eliminated.
본 실시 예에 의하면 소요부지와 재료의 최소화가 가능하면서 구조적으로도 견고한 돌출형 직각 옹벽의 시공이 가능하다.According to the present embodiment, it is possible to minimize the required site and material and to construct a structurally rigid projecting rectangular retaining wall.
도 11 및 도 12는 돌출형 45°(135°)옹벽의 코너부를 도시한 것으로, 이때에는 코너 블록(B) 일 측면의 결합부(103a)와 일반 블록(B1) 일측의 결합부(104a)를 옹벽의 전면을 이루는 직선과 45°를 이루는 위치에 일치되도록 상호 맞물려주면 되며, 자연스러운 45°코너부를 축조할 수 있다.11 and 12 illustrate corner portions of the protruding 45 ° (135 °) retaining walls, in which a coupling portion 103a on one side of the corner block B and a coupling portion 104a on one side of the general block B1 are illustrated. It is possible to interlock with each other to coincide with the straight line forming the front surface of the retaining wall to form a 45 ° position, it is possible to build a natural 45 ° corner portion.
도 13은 돌출형 옹벽의 다양한 각도 변화를 도시한 것으로, 본 실시 예의 코너 블록(B)은 블록 일 측면의 결합부(103a)가 블록의 전면에서 후면에 이르기까지 동일 반경 내에서 방사상으로 복수개가 형성되어 있으므로 인접하는 일반 블록(B1)의 결합부(104a)가 상기 결합부(103a)에 결합되는 위치를 선택하는 것에 의해 다양한 각도의 돌출형 코너부를 축조할 수 있음을 보여주고 있다.FIG. 13 illustrates various angle changes of the protruding retaining wall. The corner block B of the present embodiment has a plurality of radial portions within the same radius from the front side to the rear side of the block 103a. Since the formed portion 104a of the adjacent general block B1 is formed, it is shown that the projected corner portion of various angles can be constructed by selecting the position where the coupling portion 104a is coupled to the coupling portion 103a.
