Description

Retaining wall structure with easy angle adjustment {RETAINING WALL STRUCTURE EASY ANGLE ADJUSTMENT}

The present invention relates to a retaining wall structure with easy angle adjustment.

More specifically, it is installed on a boundary wall, snow land, cut-off site, or slope terrain to provide structural stability, and a plurality of blocks are combined so that prefabricated construction is possible. It relates to a retaining wall structure with easy angle adjustment that can be constructed in vertical or step-type construction of structures stacked with a block and can be constructed by adjusting the angle between blocks within a certain range.

In general, a retaining wall is a civil structure constructed to stabilize the slope by supporting the soil on the back side in the construction of roads, railways, industrial complexes, and rivers on the ground of cut soil.

These retaining walls are constructed in consideration of the topographical conditions and factors that act on the retaining wall after the construction of the retaining wall. Concrete retaining walls that are constructed by pouring and curing concrete and then filling the back surface of the concrete structure with earth and crushed stone or block retaining walls constructed by stacking concrete blocks made in advance on site in a factory have been widely constructed.

Concrete retaining walls effectively prevent the collapse of the ground due to the strength of the material and the weight of the concrete itself. However, there is a problem that habitats of animals disappear and natural ecosystems are destroyed.

In particular, the retaining wall stacked vertically on the shore or at the foot of a mountain has a problem in that animals cannot cross the retaining wall and thus block the movement path to isolate or cut off the animal ecosystem.

Recently, these environmental problems have been seriously recognized and a retaining wall structure in the form of an ecological block that harmonizes with the surrounding landscape is being constructed.

This block-type retaining wall structure consists of a structure in which a plurality of blocks are manufactured and then stacked by stacking each block in several stages up and down.

At this time, as a structure for a plurality of blocks to be coupled to each other in the left and right sides, a protrusion protruding outwardly in one block is formed, and a groove inwardly dug in the other block is formed so that the protrusion is inserted into the groove. It is configured to be combined in a form.

In addition, as a structure for a plurality of blocks to be coupled to each other up and down, grooves dug inward are formed on the upper and lower sides of each block, and between the grooves formed on the lower side of one block and the grooves formed on the upper side of the other block. By inserting the wedge, a plurality of blocks are firmly coupled up and down.

However, since the conventional retaining wall structure in the form of a block has to be coupled by inserting separate wedges in the process of being coupled up and down, the structure becomes complicated, and since a wedge mainly made of a concrete material must be additionally manufactured, the manufacturing cost is increased. have.

Furthermore, since the width of the wedge is made relatively smaller than the width of the block, the wedge cannot be placed between the blocks stacked on the upper and lower sides in the process of forming a structure by stacking multiple blocks up, down, left, and right When the construction of the structure is completed in this state, it is very difficult to detect the problem early because the wedge cannot be visually confirmed from the outside, and the problem of the collapse of the retaining wall constructed in a state where the bonding strength is lowered may occur.

Furthermore, when a wedge is provided between blocks in the process of stacking up and down, only a structure in which a plurality of blocks are stacked in a vertical form can be constructed, and thus, a stepped structure in which the upper and lower sides of the retaining wall structure are inclined. There is a problem of low usability because it is impossible to construct.

In addition, the conventional retaining wall structure made in the form of a block has a problem of low utilization because only planar construction is possible.

That is, in the process of stacking a plurality of blocks, it is impossible to construct an oblique or curved form, so only a flat construction is possible, so there is a very limited problem.

In order to solve this problem, a block device for a shaft and a retaining wall with easy angle adjustment was disclosed in Utility Model Registration No. 20-0255686.

However, the conventional easy block device for a shaft and retaining wall is configured to adjust the angle by separately installing a plurality of blocks and connecting rods between the blocks, then rotating both blocks based on the connecting rods to adjust the angle, but separate connecting rods must be installed together. There is a problem in that the cost increases, and further, if the angle of the block is adjusted, the aesthetics is impaired because the clearance space between the block and the connecting rod is exposed from the front side, and the problem that foreign substances are caught in the clearance space may occur. can

That is, by selectively combining and utilizing the block body 110 in the form of a block, it is possible to selectively form a structure in which an angle is deformed in a linear structure or a stepped structure or a planar structure EH.

The block body 110 is stacked in a plurality of top, bottom, left, and right to form a retaining wall structure, and is composed of a single body in the form of a block.

The block body 110 has a side protrusion 120, a side fitting groove 130, a vertical protrusion 140, a stacked fitting groove 150 and a stepped fitting groove 160 to be described later so that they can be engaged and coupled with each other. is formed, and a ring-forming groove 170 is provided so as to smoothly raise and transport the block body 110 .

At this time, when the block body 110 is described with reference to the accompanying drawings, the angle control inclined surface 111 may be formed on the left side or the right side, or each of the left and right sides.

The angle control inclined surface 111 is formed to have a tapered structure with a narrowing after rotation from the front to the rear side of the block body 110, so that the left and right widths are wider toward the front side of the block body 110, and the width increases toward the rear side. It should be made in a form that gradually narrows in width.

Accordingly, in the process in which a pair of block bodies 110 are constructed in a planar structure, the left end of one block body 110 is close to the right end of the other block body 110, so that the block body 110 from the front ) and the space between the block body 110 is not exposed.

In addition, since the angle adjustment inclined surface 111 is formed so that the left and right widths of the block body 110 become narrower from the front end to the rear end of the block body 110, a plurality of block bodies 110 have an oblique structure in which the angle is adjusted. to enable the construction of

As a space is formed between the block bodies 110 of the block body 110, the angle of the block body 110 can be adjusted through the space.

Furthermore, as shown in FIG. 4 , the block body 110 has an angle adjustment inclined surface 111 formed on the right side thereof to enable angle adjustment.

Furthermore, as shown in FIG. 5 , when the angle control inclined surface 111 is formed on each of the left and right sides of the block body 110 , one pair of block bodies 110 is angled with each other in the process of adjusting the angle. A free space is formed in the space between the angle adjustment inclined surface 111 formed on one side of the block body 110 and the angle adjustment inclined surface 111 formed on the other side of the other block body 110, so that the angle adjustment inclined surface facing each other ( 111) is adjusted, so that the angle can be easily adjusted and at the same time, the space between the pair of block bodies 110 is not exposed, thereby providing a beautiful appearance.

At this time, the angle adjustment inclined surface 111 may be formed in a shape inclined from about 3° to 10° from the side surface of the block body 110 .

Preferably, it may be formed in a shape inclined by about 5°.

This is, when the angle of the angle adjustment slope 111 is made less than 3°, it is not possible to secure a sufficient inclination angle of the block body 110 during construction of the retaining wall structure of the oblique (curved) structure, and the angle is made more than 10° On the ground, there is a problem in that durability is reduced due to a decrease in the contact area between the block bodies 110 in the process where the space between the block bodies 110 is expanded and the block bodies 110 are stacked up and down.

The side protrusion 120 is formed to protrude outwardly on one side of the block body 110 , and is formed to be elongated upward and downward, as shown in the accompanying drawings, and includes a hydraulic inclined surface 121 .

This side protrusion 120 is to be fitted into a side fitting groove 130 to be described later, so that a pair of block bodies 110 are engaged with each other and coupled.

The hydraulic inclined surface 121 is provided on the front and rear surfaces of the side protrusions 120 formed so that the width gradually becomes narrower toward the outside from the block body 110 .

The side fitting groove 130 is formed in a shape that is dug inward on the other side of the block body 110, is formed in a shape corresponding to the side protrusion 120, is formed to be elongated up and down, and includes a dark inclined surface 131. is composed by

The side fitting groove 130 provides a space in which the side protrusion 120 is fitted.

The female inclined surface 131 is formed in a shape corresponding to the male inclined surface 121 and is provided on the front and rear surfaces of the side fitting grooves 130 so that the width gradually increases toward the outside from the block body 110 .

As the female inclined surface 131 repeats the process of contacting or dropping off the male inclined surface 121 in the process of fitting the side protrusion 120 to the side fitting groove 130, the side fitting groove 130 has the side surface. It performs a function of guiding the protrusion 120 to be fitted in the correct position.

That is, the side protrusion 120 having a shape that is gradually narrowed toward the outside by the male inclined surface 121 is fitted into the side fitting groove 130 having a shape that is gradually narrowed toward the inside by the female inclined surface 131, so that a pair of the block body 110 to be firmly engaged with each other, it is possible to prevent in advance the problem that the block body 110 is coupled to each other eccentrically.

At this time, the size of the space in which the side fitting groove 130 is formed may be the same as or larger than the size of the side protrusion 120 .

Accordingly, in the process in which the side protrusion 120 formed in one block body 110 is fitted into the side fitting groove 130 formed in the other block body 110, sufficient formed by the side fitting groove 130 is sufficient. Since it is fitted into the space, even if the side protrusion 120 and the side fitting groove 130 are spaced apart by a predetermined distance by the angle adjustment inclined surface 111 formed on each of the pair of block bodies 110, the male inclined surface 121 and the arm Due to the inclined surface shape of the inclined surface 131 , the side protrusion 120 may be smoothly inserted into the side fitting groove 130 .

The vertical protrusion 140 is formed in a shape protruding outward from the upper side of the block body 110, and a stacked fitting groove 150 or a stepped fitting groove to be described later in the process in which the block body 110 is stacked up and down ( 160) is optionally inserted.

In addition, the vertical protrusion 140 may be formed in a cylindrical shape having a circular cross section, and may be formed in a downward beam shape in which the diameter gradually decreases from the lower side to the upper side.

Accordingly, in the process of selectively inserting the vertical protrusion 140 into the stacked fitting groove 150 or the stepped fitting groove 160 to be described later, the vertical protrusion 140 has a tapered surface in the inclined shape for the stacked fitting. In order to be easily inserted into the groove 150 or the stepped fitting groove 160, and further, the vertical protrusion 140 having a circular cross section is inserted into the stacked fitting groove 150 or the stepped fitting groove 160. The block body 110 located on the lower side and the block body 110 located on the upper side can be rotated in the horizontal direction, so that the angle can be easily adjusted.

The stacked fitting groove 150 is formed in a shape that is dug inward on the lower side of the block body 110, and is formed to communicate with the left and right sides in the middle between the front and back surfaces.

The stacked fitting groove 150 provides a space in which the vertical protrusion 140 of the block body 110 located at the lower side is inserted in the process in which a plurality of block bodies 110 are stacked up and down.

When described with reference to the accompanying drawings, the spacing maintaining unit 180 is formed in the form of a long cylinder upward and downward so as to be in close contact with the inclined angle adjustment inclined surface 111 formed on the side of the block body 110, , As in FIGS. 13 and 14, it is provided in a retaining wall structure constructed in a flat shape, or, as in FIGS. 15 and 16, in the process of angle adjustment and diagonal construction, the distance between a pair of block bodies 110 It may be provided when the spaced apart.

Preferably, the gap maintaining unit 180 is provided between the pair of block bodies 110, and the angle control inclined surface 111 formed on the left side or the right side or the left side and the right side of the block body 110, respectively. By being fitted into the space formed between the pair of block bodies 110, the adhesion between the plurality of block bodies 110 is improved so that the retaining wall structure is firmly constructed.

When explaining an example in which the spacing maintaining unit 180 is installed on the block body 110 in which the angle adjustment slope 111 is formed on each of the left and right sides with reference to the accompanying drawings, first, when the retaining wall structure is constructed in a flat shape , A gap maintaining part 180 is provided between a pair of block body 110, as shown in FIG. provided in space.

At this time, the outer circumferential surface of the gap maintaining unit 180 is in close contact with both the side protrusion 120 formed on one side of the block body 110 and the side fitting groove 130 formed on the other side of the block body 110 of the block body 110 . It prevents the angle from being deformed and allows the shape of the planar retaining wall structure to be maintained.

In addition, as shown in FIGS. 15 and 16 , when the retaining wall structure is constructed in an oblique shape, a gap maintaining unit 180 is provided between a pair of block bodies 110 for which angle adjustment is completed, and the gap is maintained. The part 180 is in close contact with the angle control inclined surface 111 of the block body 110 .

At this time, as shown in FIG. 15 , the gap maintaining unit 180 is a pair of block body 110 rear ends are farther away from each other due to the inclined shape of the angle control inclined surface 111 toward the front side of the block body 110 . Thus, it is possible to construct an oblique retaining wall structure having a gentle inclination angle.

As another example, as shown in FIG. 16 , the rear ends of the pair of block bodies 110 become adjacent to each other as the distance maintaining unit 180 moves toward the rear side of the block body 110 , and thus, as shown in FIG. It is possible to construct an oblique retaining wall structure with a relatively steeper inclination than the retaining wall structure.

That is, the gap maintaining unit 180 is provided between the pair of block bodies 110, so that flat construction is easy, and the distance between the block bodies 110 is adjusted in the process of diagonal construction. As a result, by limiting the angle of inclination at which the plurality of block bodies 110 are inclined, it is possible to perform constant construction.

According to this configuration, the retaining wall structure with easy angle adjustment according to the present invention is installed on a boundary wall, snow land, cut-off site, or slope terrain to provide structural stability, and a plurality of blocks are combined so that prefabricated construction is possible, Since the male and female fitting grooves are formed in two rows, vertical or step-type construction of selectively stacked structures is possible.

In addition, a plurality of blocks are stacked and composed of a structure in which the blocks and blocks are interlocked with each other, so that a separate wedge is not required, thereby minimizing the manufacturing cost and preventing a decrease in bonding strength due to the use of the wedge in advance. can

In addition, since the construction is possible by adjusting the angle between the blocks within a certain range, it is possible to construct not only a flat retaining wall structure but also a diagonal retaining wall structure inclined at various angles.

In the above description, various embodiments of the present invention have been presented and described, but the present invention is not necessarily limited thereto. It can be seen that branch substitutions, transformations and alterations are possible.
