Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings.
As shown in
Here, the first and second fastening protrusions 21 and 22 may be disposed to correspond to each other and protrude in mutually opposite directions, and the first and second fastening grooves 31 and 32 may be disposed to be misaligned with one another to be concave in mutually facing directions.
At this time, the first fastening groove 31 may be disposed to be adjacent to the first fastening protrusion 21, and the second fastening groove 32 may be disposed to be adjacent to the second fastening protrusion 22.
In addition, the first and second fastening protrusions 21 and 22 may be inserted and fastened to a first fastening groove or a second fastening groove of a different adjacent assembly block 1.
Further, the first and second fastening grooves 31 and 32 may have a first fastening protrusion or a second fastening protrusion of a different adjacent assembly block 1 inserted and fastened thereto.
Next, the area of the first side surface 11 of the body portion 10 where the first fastening protrusion 21 is formed may be the same as the area of the second side surface 12 of the body portion 10 where the second fastening protrusion 22 is formed.
However, the area of the first side surface 11 of the body portion 10 where the first fastening protrusion 21 is formed may be different from the area of the third side surface 13 of the body portion 10 where the first fastening groove 31 is formed, or may be different from the area of the fourth side surface 14 of the body portion 10 where the second fastening groove 32 is formed.
Here, the area of the first side 11 of the body 10 may be smaller than the area of the third side 13 or the fourth side 14 of the body 10.
The reason for this is that the assembly block 1 is formed in a straight shape so that the triangle unit assembly block can be easily assembled.
Therefore, the triangle unit assembly block does not easily deform or collapse when an external force due to an external impact is applied to the assembly, by dispersing the external force.
Further, the first fastening protrusion 21 may have first and second protrusion lines 21a and 21b formed on both sides thereof and the second fastening protrusion 22 may have third and fourth protrusion lines 22a and 22b formed on both sides thereof.
Here, the first and second protrusion lines 21a and 21b or the third and fourth protrusion lines 22a and 22b are formed from the upper surface 15 to the lower surface 16 of the body portion 10, and may protrude in a direction perpendicular to the third side surface 13 or the fourth side surface 14 of the body portion 10.
At this time, the first and second protrusion lines 21a and 21b or the third and fourth protrusion lines 22a and 22b may have a hemispherical cross section, but the present invention is not limited thereto, and it is possible to be made in various forms.
In addition, the first fastening groove 31 may have first and second groove lines 31a and 31b formed recessed to both inner side surfaces and the second fastening groove 32 may have third and fourth grooves lines 32a and 32b formed recessed to both inner side surfaces.
Here, the first and second groove lines 31a and 31b or the third and fourth groove lines 32a and 32b are formed from the upper surface 15 to the lower surface 16 of the body portion 10, and may be concave in a direction perpendicular to the first side surface 11 or the second side surface 12 of the body portion 10.
At this time, the first and second groove lines 31a and 31b or the third and fourth groove lines 32a and 32b may have a hemispherical cross section, but the present invention is not limited thereto, and it is possible to be made in various forms.
For example, the sectional shapes of the first and second groove lines 31a and 31b or the third and fourth groove lines 32a and 32b may be the same as those of the first and second protrusion lines 21a and 21b or the third and fourth protrusion lines 22a and 22b.
The reason for this is that the first and second groove lines 31a and 31b or the third and fourth groove lines 32a and 32b, and the first and second protrusion lines 21a and 21b or the third and fourth protrusion lines 22a and 22b, can be easily fastened to each other.
As described above, a groove line concave towards both inner side surfaces is formed on the first and second fastening grooves 31 and 32 respectively, and a protrusion line protruding towards both sides is formed on the first and second fastening protrusions 21 and 22 respectively, thereby the coupling force between the assembly blocks can be improved, and the coupling force can be greatly enhanced even in the triangular unit assembly.
Further, the areas of the first and second fastening grooves 31 and 32 may be larger than the areas of the first and second fastening protrusions 21 and 22.
The reason for this is so that the first and second fastening grooves 31 and 32 and the first and second fastening protrusions 21 and 22 are fastened together smoothly.
If the areas of the first and second fastening grooves 31 and 32 are smaller than or equal to the areas of the first and second fastening protrusions 21 and 22, the fastening of the first and second fastening grooves 31 and 32 with the first and second fastening protrusions 21, 22 may be difficult.
Therefore, the first and second fastening protrusions 21 and 22 can be easily fastened to the first fastening groove or the second fastening groove of the adjacent assembly block 1.
Next, a plurality of convex portions 40 may be formed on the upper surface 15 of the body portion 10.
Here, the plurality of convex portions 40 may be arranged at regular intervals.
The reason for this is that the assembly blocks 1 stacked on each other can have a water dripping passage by forming a certain space by the convex portions 40, and it is for the purpose of having water quickly drained between the assembly blocks 1 stacked on each other.
However, the convex portions 40 may be arranged at different intervals depending on the different cases.
For example, the gap between the convex portions 40 located in the central region of the upper surface 15 of the body portion 10 may be narrower than the gap between the convex portions 40 located on the edge region.
The reason for this is that the assembly blocks 1 stacked on each other can have a water dripping passage by forming a certain space by the convex portions 40, so that more water can be drained through the edge region than the central region of the assembly blocks stacked on each other.
In another case, the gap between the convex portions 40 located on the central region of the upper surface 15 of the body portion 10 may be wider than the distance between the convex portions 40 located on the edge region.
The reason for this is that the assembly blocks 1 stacked on each other can have a water dripping passage by having a certain space by the convex portions 40, so that more water can be drained through the central region than the edge region of the assembly blocks stacked on each other.
Further, a plurality of convex portions 40 are formed on the upper surface 15 of the body portion 10, and the lower surface 16 of the body portion 10 is a flat plane without the convex portions 40.
In another case, a plurality of convex portions 40 are formed on the upper surface 15 of the body portion 10, and the lower surface 16 of the body portion 10 is a flat planar surface.
Here, the flat lower surface 16 of the body portion 10 may be in contact with a plurality of convex portions 40 formed on the upper surface 15 of the body portion 10.
Further, the upper surface of the convex portion 40 may be a flat planar surface, and the side surface of the convex portion 40 may be an inclined surface.
Here, the angle between the side surface of the convex portion 40 and the upper surface 15 of the body portion 10 may be an obtuse angle.
In some cases, however, the angle between the side surface of the convex portion 40 and the upper surface 15 of the body portion 10 may be a right angle.
Next, first and second fastening grooves 31 and 32 may be disposed between adjacent convex portions 40.
That is, the plurality of convex portions 40 and the first and second coupling grooves 31 and 32 may be disposed misaligned with each other.
The reason for this is to secure a space in which the convex portion 40 can be formed on the upper surface 15 of the body portion 10.
As described above, the present invention provides a combined function single block with a connecting block function and a frame block function that can safely and easily combine a triangle unit assembly in a double row longitudinal, lateral, and vertical direction, thereby enabling work to be done easily even by a non-expert when building a landslide preventing draining retaining wall using an assembly block, and because foundation work is unnecessary, there's less influence from seasons and bending moments don't occur structurally and thereby the cost-efficiency is excellent and the stability is suitable to constructing a semi-permanent structure such as a landslide preventing retaining wall as an earthquake-proof assembly.
As shown in
Here, the first and second fastening protrusions 21 and 22 are arranged so as to correspond to each other and protrude in opposite directions to each other and the first and second fastening grooves 31 and 32 may be disposed so as to be misaligned with each other and convex in a direction mutually facing each other.
At this time, the first fastening groove 31 may be disposed adjacent to the first fastening protrusion 21, and the second fastening groove 32 may be disposed adjacent to the second fastening protrusion 22.
Further, the first fastening protrusion 21 may have first and second protrusion lines 21a and 21b formed on both sides thereof and the second fastening protrusion 22 may have third and fourth protrusion lines 22a, 22b formed on both sides thereof.
At this time, the first and second protrusion lines 21a and 21b or the third and fourth protrusion lines 22a and 22b may have a hemispherical cross section, but the present invention is not limited thereto, and it is possible to be made in various forms.
In addition, the first fastening groove 31 is formed with first and second groove lines 31a and 31b recessed in both inner side surfaces respectively and the second fastening groove 32 is formed with third and fourth grooves Lines 32a and 32b may be formed.
In addition, the first fastening groove 31 may have first and second groove lines 31a and 31b formed recessed to both inner side surfaces and the second fastening groove 32 may have third and fourth grooves lines 32a and 32b formed recessed to both inner side surfaces.
At this time, the first and second groove lines 31a and 31b or the third and fourth groove lines 32a and 32b may have a hemispherical cross section, but the present invention is not limited thereto, and it is possible to be made in various forms.
Next, a plurality of convex portions 40 may be formed on the upper surface 15 of the body portion 10.
Here, the upper surface of the convex portion 40 may be a flat planar surface, and the side surface 42 of the convex portion 40 may be an inclined surface.
Here, the angle between the side surface 42 of the convex portion 40 and the upper surface of the body portion 10 may be an obtuse angle.
In some cases, however, the angle between the side surface 42 of the convex portion 40 and the upper surface of the body portion 10 may be a right angle.
Further, the convex portions 40 according to a first exemplary embodiment of the present invention, as shown in
Here, the plurality of convex portions 40 may be arranged at regular intervals.
The reason for this is that the assembly blocks 1 stacked on each other can have a water dripping passage by forming a certain space by the convex portions 40, and it is for the purpose of having water quickly drained between the assembly blocks 1 stacked on each other.
However, the plurality of convex portions 40 may be arranged at different intervals depending on the different cases.
For example, the gap between the convex portions 40 located in the central region of the upper surface 15 of the body portion 10 may be narrower than the gap between the convex portions 40 located on the edge region.
The reason for this is that the assembly blocks 1 stacked on each other can have a water dripping passage by having a certain space by the convex portions 40, so that more water can be drained through the central region than the edge region of the assembly blocks stacked on each other.
As shown in
Here, at the center of the triangle unit assembly 100, a unit large space in which a large amount of water is rapidly drained is formed.
In addition, as shown in
For example, the first fastening protrusion of the first assembly block 1 may be inserted into the first fastening groove of the second assembly block 2, and the second fastening protrusion of the first assembly block 1 may inserted into the second fastening groove of the third assembly block 3.
In addition, the first fastening protrusion of the fourth assembly block 4 is inserted into the first fastening groove of the first assembly block 1 and the second fastening protrusion of a fifth assembly block 5 may be inserted into the second fastening groove of the first assembly block 1.
In this manner, the horizontal assembly 200 includes six unit large spaces 50 of each triangle unit assembly, and a hexagonal large space 60 is formed at the center of the horizontal assembly 200.
Next, the structure 300 may then be formed by stacking at least two horizontal assemblies 200 in a vertical direction.
Here, a plurality of horizontal assemblies 200 are further extended in the horizontal direction, and are stacked to be connected to each other in a vertical direction again, thereby enabling building a landslide prevention draining retaining wall.
That is, a plurality of horizontal assemblies 200 having six triangular unit large spaces 50 and one central hexagon-shaped large space 60 may be connected in the horizontal direction and the vertical direction.
Here, when at least two horizontal assemblies 200 are stacked in the vertical direction, the triangle unit assemblies 100 adjacent to each other can be stacked to be misaligned with each other.
The reason for this is that, by stacking the adjacent triangular unit assemblies 100 mutually adjacent to each other to be misaligned, there is an advantage that the fastening force between the assembly blocks 1 is large, so that even if an impact is applied in the horizontal direction, it can withstand.
Further, the structure 300 in which the triangular unit assemblies 100 are stacked to be misaligned can elastically disperse an external force when an external impact is present, even when elongation, shrinkage, differential settlement or the like occurs between the assembly blocks, so it cannot be easily deformed or collapsed.
In this case, when an external force such as a tidal wave, a storm, or an earthquake is applied to the structure by a supernatural disaster, the assembly blocks of the present invention can elastically disperse the external force, so with the strong support strength against external force, deformation can be prevented or the damage can be minimized.
As shown in
Then, at least two triangle unit assemblies are horizontally connected to form a horizontal assembly in step S13.
Next, at least two horizontal assemblies may be stacked in a vertical direction to form a structure in step S15.
Here, when stacking at least two horizontal assemblies in the vertical direction, mutually adjacent triangle unit assemblies can be stacked to be misaligned with each other.
Like this, since the present invention is a combined function single block with a connecting block function and a frame block function that can safely and easily combine a triangle unit assembly in a double row longitudinal, lateral, and vertical direction, work is enabled to be done easily even by a non-expert when building a landslide preventing draining retaining wall using an assembly block, and because foundation work is unnecessary, there's less influence from seasons and bending moments don't occur structurally and thereby it is suitable for constructing a semi-permanent structure such as a landslide preventing retaining wall as an earthquake-proof assembly and the cost-efficiency and stability are also excellent.
In addition, because the present invention is a triangle unit assembly, bending moments don't occur, so an earthquake-resistent retaining wall may be easily and simply built in a prefabricated manner, and can be utilized for various purposes such as a breakwater, a retaining wall, a shore protection, etc., by adjusting the size of the blocks in accordance with the site conditions, and because the present invention does not require foundation work, the structure can be firmly built even in mountainous areas and soft grounds.
Further, since the present invention does not perform concrete pouring work on site, it is advantageous in that the work in water or near the water is easy, and because finished products are used, the construction period can be shortened, and the assembling work is simple and easy to open and repair.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation in the scope of the appended claims. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims, and these modifications should not be understood individually from the technical idea or viewpoint of the present invention.
