Abstract
본 발명은 옹벽을 지형조건에 따라 수직형이나 계단형으로 쌓을 수 있는 블록이다.The present invention is a block that can be stacked in a vertical or step shape depending on the topographic conditions.
원통형(Cylinder)의 원주면(圓周面)과 사각 성형체(星形體 Astroid)의 네벽이 원호(圓弧)로 된 호상면(弧狀面)을 결합시킨 외형을 갖춘 것으로 원통형 원주면과 사각 성형체 네벽의 호상면의 곡률(曲率)을 같게하여 줌으로서 조합하기에 따라 옹벽을 쉽고 견고하게 구축할 수 있으며 원통형과 사각 성형체에 관통된 구멍 양단부위에 대응시켜 요철형의 보스(boss)를 만들어 상하로 잘 끼워지게 함으로서 이들을 적층시 맞물려 결합시켜 쌓을 때 상하좌우로 토압(土壓)에 의하여 미끄러져 빠지거나 붕괴될 염려가 없으며 또한 원통형이나 사각 성형체의 관통된 각 구멍에는 토사를 채울수도 있어 물이 잘스며 나갈 수 있고 화초를 심어 조경미를 향상시킬 수 있는 등의 특징을 갖는 조경성이 탁월한 다양한 기능을 갖는 블록을 제공하는 것이다.Cylindrical circumferential surface of the cylinder and four walls of the square Astroid combine the arcuate arc surface with the cylindrical circumferential surface and the square molded body four walls. The retaining wall can be easily and firmly constructed by combining the same curvature of the arc surface of the torsion surface. The boss of the uneven shape is made up and down well in correspondence with both ends of the hole penetrated through the cylindrical and square moldings. When they are stacked together, they are interlocked and stacked so that they do not slip, collapse or collapse due to earth pressure when they are stacked. Also, each perforated hole of a cylindrical or square molded body can fill the soil. It is to provide a block having a variety of functions with excellent landscaping characteristics, such as being able to go out and planting flowers to improve the landscape beauty.
Description
본 발명은 옹벽, 울타리, 담장, 조경, 호안, 보도 등에 적용되는 다기능 블록에 관한 것으로, 어떠한 곡선 형태를 가진 지형이라도 곡선 그대로 자연스럽게 설치가 가능하면서, 식생또한 가능하여 조경미를 한층 돋보이게 할수있고, 동시에 조적시에는 상하전후좌우에 대하여 결착력을 크게 향상시키도록 한 것이다.The present invention relates to a multi-functional block applied to retaining walls, fences, fences, landscaping, lakes, footpaths, etc., and it is possible to naturally install any curved terrain as it is, while also allowing vegetation to enhance the beauty of the landscape. In the case of masonry, the binding force is greatly improved for up, down, left, and right.
이 기술분야에 속한 종래의 통상적인 축조방법중에서 옹벽 축조 방법을 대표적 예를 들어 설명하여 보면 구릉지를 수직으로 깎아 거푸집을 대고 콘크리트를 주입하여 형틀에 의하여 축석모양을 한 옹벽을 축조하는 방법이 보편화되어 있으나 이는 일률적으로 절벽같은 수직형의 옹벽으로 국한하여 단조롭기 때문에 블록으로 다양한 옹벽을 구축하려는 방안이 안출되왔다.Representative examples of the retaining wall construction method in the conventional conventional construction methods belonging to this technical field is a method of constructing a retaining wall shaped like a masonry by a mold by cutting a hill vertically and applying a formwork to the formwork. However, since this is monotonically limited to vertical retaining walls, such as cliffs, a plan has been devised to build various retaining walls with blocks.
그러나 대부분 옹벽축조용 블록은 조경성과 견실성을 고루 갖추지 못하였고 대부분 풀뿌리를 내릴 수 없는 토양을 봉쇄하는 밀폐형 옹벽이어서 자연을 훼손하는 옹벽축조가 통례였다. 또한 풀뿌리를 내리는 토양의 공간을 노출시킨 블록도 있으나 토압에 밀려 붕괴될 수 있는 취약한 구조로 되어있을 뿐이다.However, most retaining wall construction blocks are not well-equipped with landscaping and robustness, and most retaining wall constructions are damaging to nature because they are hermetic retaining walls that block soil that cannot be grassrooted. There is also a block that exposes the space of the grass that leaves the grassroots, but it has a fragile structure that can collapse under pressure.
본 발명의 블록은 자연의 경관을 훼손하지 않고 옹벽을 지형의 조건에 따라 알맞는 시공을 할수있게 하여 수직형은 물론 구릉지의 경사도에 따라 계단형으로 쌓을 수 있고 직선이 아닌 구릉지를 싸고 도는 곡선을 따라 구불구불 휘여진 옹벽을 자유자재로 쌓을 수 있는 다기능 블록을 안출하고자 하는데 있고 또한 블록의 구멍에 토사를 채워 화초를 심어 조경미를 향상시키는 동시에 축성된 블록이 토압에 의하여 밀려 빠져 붕괴되지 않도록 상하전후좌우로 완벽하게 결합하는 구조로 구성하는데 목적을 두고 있다.The block of the present invention allows the retaining wall to be appropriately constructed according to the terrain conditions without compromising the natural landscape, so that it can be stacked stepwise according to the slope of the hill as well as the vertical type. As a result, it is trying to create a multifunctional block that can freely stack a curved retaining wall, and it also fills soil in the hole of the block to plant flowers to improve the landscape and at the same time prevents the built-up block from being pushed down and collapsed by earth pressure. The purpose is to construct a structure that perfectly combines from side to side.

이하, 본 발명의 구성 및 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 평면구성은 제1도에서 보이는 바와같이 반지름(ℓ/2)이 동일한 원을 서로 외접되게 그리면 네 개의 원이 네 개의 점(a,b,c,d)에서 접하게 되고 이때 각원의 중심(O1,02,03,04)을 서로 연결시키면 기하학상 정사각형(O1,02,03,04)이 되는 것은 물론이고 각 접점(a,b,c,d)이 이루는 원호의 길이가 동일한 별모양의 성형체도 얻을 수 있게 된다.In the planar configuration of the present invention, as shown in FIG. 1, when a circle having the same radius (l / 2) is drawn outward from each other, four circles are in contact with four points (a, b, c, d), and the center of the circle is When (O 1 , 0 2 , 0 3 , 0 4 ) is connected to each other, it becomes a geometric square (O 1 , 0 2 , 0 3 , 0 4 ) and each contact (a, b, c, d) Star shaped bodies having the same arc length can also be obtained.
바로 여기에서 본 발명의 블록평면형상이 구성된 것인데, 즉 네 개의 원중에서 하나의 원을 선택하고서 선택된 원에다 성형체를 결합시킨 일체화 형상을 본 발명 블록의 평면형상으로 하고 있는 것이다. 다시 말하면 제2도에서와 같이 제1도에서 생긴 원형과 사각 성형체를 입체적으로 벽면을 형성하여 생긴 제2(a)도와 (b)도를 합친 제2(c)도의 형상이 본 발명이 창출한 블록의 외형인 것이다.Herein, the block plane shape of the present invention is configured, that is, the integrated shape in which one circle is selected from four circles and the molded body is bonded to the selected circle is used as the planar shape of the block of the present invention. In other words, as shown in FIG. 2, the shape of FIG. 2 (c), which combines the 2 (a) and (b) diagrams formed by forming the three-dimensional wall surface of the circular and square molded bodies formed in FIG. It is the appearance of the block.
이때 제2(a)도의 원통형의 원주면과 제2(b)도의 사각 성형체의 네 벽이 원호가 동일하기 때문에 360°원통형둘레의 어느 위치에도 사각 성형체를 결합시킬 수 있는 것이며 바로 이 원리가 제7도에서 보는 바와 같이 정원에 화단이나 작은 연못을 만들 때 정원에 블록의 곡선 배열이 자유자재로 연출할 수 있게 되는 것이다.At this time, since the four walls of the cylindrical circumferential surface of FIG. 2 (a) and the square shaped body of FIG. 2 (b) have the same arc, the rectangular shaped body can be combined at any position of the 360 ° cylindrical circumference. As you can see from the 7th degree, when you make a flower bed or a small pond in the garden, you can freely arrange the curvilinear arrangement of blocks in the garden.
이와 같은 설계에 의해서 입체를 이룬 상하면의 원과 사각 성형체 중앙에 각각 상하수직으로 제3(b)도와 같은 원통구멍과 제3(a)도와 같이 성형체의 중앙에 사각구멍을 형성시키면 제3(c)도와 같이 다기능 블록이 만들어지며 또한 원통형과 사각 성형체의 관통된 구멍의 상하의 양단 주연부에 대응시켜 요철형의 집합부를 만들어 잘 끼워지게 함으로서 이들을 상하측으로 결합시켰을 때 걸림구조가 확보되며 제6도의 블록의 평면배열에서도 알수있듯이 원통형의 원주면을 같은 곡률을 갖는 사각 성형체의 호상면이 꼭껴안아 서로 전후좌우로 빠져 나갈 수 없도록 결속된 구조로 구성되었기 때문에 옹벽을 축성하였을 때 토압에 의하여 상하전후좌우로 미끄러 빠져 붕괴될 수 없는 완벽한 결착력을 발휘하는 것이다.According to such a design, a cylindrical hole as shown in FIG. 3 (b) and a rectangular hole as shown in FIG. As shown in Fig. 6, the multi-functional block is made, and the upper and lower peripheral edges of the cylindrical holes and the rectangular molded body correspond to the periphery of the upper and lower ends to form a set of concave-convex shapes so as to fit well. As can be seen from the planar arrangement, the cylindrical circumferential surface of the rectangular shaped body having the same curvature is formed so that it is bound so that it can not escape to each other from side to side. It is a perfect binding that can not fall out and collapse.
제6도의 블록의 평면배열을 다시 관찰하면 원통의 원둘레를 사등분하여 요흠을 형성시켰고 또한 사각 성형체의 중공부분에도 요흠을 형성시켜 장마를 대비한 배수구를 만들었다.Observing the planar arrangement of the block of FIG. 6 again, the circular periphery of the cylinder was divided into quadrants to form recesses, and also the recesses were formed in the hollow portions of the rectangular molded body to make drainage holes for the rainy season.
제3도의 평면도와 사시도에서 보듯이 사각 형성체의 네 모서리의 예각을 적당히 짤라서 운반시 블록 꼬리의 두 모서리의 파손을 방지하였다. 제4도는 두 개의 본 발명블록을 합쳐 일체로 만든 쌍블록이며 제5도는 세 개의 블록을 합쳐 일체로 만든 복쌍블록이다.As shown in the plan view and perspective view of FIG. 3, the acute angles of the four corners of the quadrangular body were cut appropriately to prevent breakage of the two corners of the block tail during transportation. FIG. 4 is a double block made by combining two blocks of the present invention and FIG. 5 is a double block made by combining three blocks.
본 발명을 실시예를 들어 더 자세히 설명하면 다음과 같다.The present invention will be described in more detail with reference to Examples.
제8도과 같이 옹벽을 수직으로 축조를 하게 되면 옹벽면의 선은 파도형상으로 보이게 된다. 이때 옹벽을 조적할 때 첫 단계에서 본 발명 블록의 원통형쪽을 왼쪽방향으로, 사각 성형체쪽을 오른쪽방향으로 하여서 제품 마디마다 줄을 이어서 쌓고 그위의 둘째단계에서 쌓을때는 블록의 원통형쪽을 오른쪽방향으로 사각 성형체쪽을 왼쪽방향으로 바꾸어서 첫단계의 블록들이 접합되어 단절된 마디부분 위에 둘째단계 블록의 중앙이 위치하도록 덮어서 쌓고 그 위에 셋째 단계에서는 다시 블록의 방향을 첫째 단계와 같이 조적하면 정면에서 보이는 것과 같이 연결 부위가 상하 지그재그로 엇갈리도록 축조되어 견고한 옹벽을 구성하는 것이다. 가령 원통형과 사각 성형체를 각각 독립되게 분리하여서 제8도과 같이 옹벽을 쌓았다고 가정을 하였을 때 원통형은 원통형 기둥만을 이루고 사각 성형체는 사각 성형체기둥을 이루면서 분리되 쌓아질뿐 원통형과 사각 성형체들의 접합면에 생기는 틈새는 영원히 맞물릴 수 없는 간격이 되는 것이다. 바로 이 간격을 없애기 위해 위와 아래 단계에서 엇갈리게 접하도록하기 위하여 원통형과 사각 성형체를 묶어서 하나의 블록으로 창출한 것이 본 발명의 핵심요소중의 하나이다. 제9도와 같이 수직옹벽을 축조하면 원통의 원둘레가 윗단과 아랫단의 사각 성형체의 외부로 돌출되는데 이때 이 부분에 토사를 충만시켜 화초를 심어 조경성을 살렸다. 또한 제8도과 제10도에서와 같이 쌍블록 또는 복쌍블록을 이용하여 계단식으로 옹벽을 축조하여 화초를 심을 수 있게 하였는데 이 쌍블록과 복쌍블록은 옹벽축성의 견실성과 공사기간을 단축시키는데 아주 효과적이다. 또한 옹벽축성시 본 발명의 블록과 쌍블록을, 그리고 쌍블록과 복쌍블록을 각각 바꾸어서 혼용하면 뒷면에 돌출된 복쌍블록의 원통형 구멍과 사각 성형체 구멍 그리고 몸통의 굴곡된 곡선부위를 채워 다져진 골재와 흙이 맞물려 일체화 되기 때문에 토압에 더욱 견실성을 유지할 수 있다.As shown in FIG. 8, when the retaining wall is vertically constructed, the line of the retaining wall surface is shown as a wave shape. At this time, when laying the retaining wall, the cylindrical side of the block of the present invention in the first step in the left direction, the square molded body in the right direction in a row for every product segment, and when stacked in the second step above the cylindrical side of the block in the right direction By turning the rectangular molded body to the left side, the blocks of the first stage are joined and stacked so that the center of the second stage block is located on the disconnected node, and in the third stage, the direction of the block is again assembled as in the first stage, as seen from the front. The connecting parts are constructed to be staggered up and down to form a rigid retaining wall. For example, assuming that the cylindrical and square molded bodies are separately separated and retaining walls are stacked, as shown in FIG. The gap is a gap that cannot be interlocked forever. One of the key elements of the present invention is to create a single block by tying cylindrical and square molded bodies so as to be in contact with each other at the upper and lower stages to eliminate this gap. When the vertical retaining wall is constructed as shown in FIG. 9, the cylindrical circumference protrudes to the outside of the square molded body of the upper and lower ends. At this time, the soil is filled with soil to plant the landscape. In addition, as shown in FIGS. 8 and 10, double or double double blocks can be used to build retaining walls in a stepwise manner to plant flowers. These double blocks and double double blocks are effective for shortening the retaining wall construction and shortening the construction period. . In addition, when the retaining wall is constructed, the block and the double block of the present invention and the double block and the double block are mixed, respectively, and the aggregate and soil are filled by filling the cylindrical hole, the square molded hole, and the curved curved part of the body. Since the mesh is integrated, it is possible to maintain more robustness to earth pressure.
이제까지 대표적예로서 옹벽의 축조와 관련하여 설명하였으나 옹벽의 축조는 물론이고 호안, 울타리, 조경, 보도 등에 광범위하에 적용할 수 있음도 밝혀둔다.As a representative example, the construction of the retaining wall has been described as a representative example, but it is also revealed that the construction of the retaining wall can be applied to a wide range of fields such as shores, fences, landscaping, and sidewalks.
본 발명의 블록은 동일한 반경을 갖는 네 개의 원이 서로 외접된 상태에서 하나의 원과 사각성형체를 일체로 하고 있는 구조이므로 다양한 곡선형태로의 설치가 가능하여 구릉지의 원형을 훼손하지않고 축성하여 블록 중공부에 화초를 심을 수 있어 시각적으로 자연적인 조경미가 한층 돋보일뿐 아니라 사각 성형체와 원의 위치를 엇갈리게 축조하거나 사락 성형체를 토압을 받는 쪽으로 향하게 하면서 원의 위치와 서로 엇갈리게 축조하게 되면 구조물벽체로서의 결착력이 더한층 견고하게 되어 안전사고의 유발을 방지할 수 있는 유용한 발명인 것이다.In the block of the present invention, since four circles having the same radius are circumscribed to each other, one circle and a rectangular molded body are integrated so that various blocks can be installed in a curved form without damaging the original shape of hilly areas. The plant can be planted in the hollow to visually enhance the natural beauty of the landscape, as well as staggering the square and the circle positions, or facing the earth pressure, while forming the staggering force as the structure wall. This is a useful invention that can be more robust to prevent the occurrence of safety accidents.
