Description

{Interlock Block For Wall Construction And Its Construction Method}

The present invention relates to an interlock block for constructing a retaining wall to prevent collapse due to soil loss on a slope of a fill or cut land of a road or river, etc. due to civil engineering work, and more particularly, to an interlock block for constructing a retaining wall having an interlock structure that allows the block body to rotate freely within a predetermined angle range on both the left and right sides, and an anti-slip structure that allows it to be used selectively depending on the surrounding environment.

In general, a retaining wall for a cut site is a wall structure that resists the earth pressure caused by heavy rain and prevents the cut site from collapsing due to soil runoff. These retaining walls can be broadly classified into a monolithic type that is constructed as an integral part of the cut site using materials such as concrete, and a masonry type that is constructed using materials such as blocks.

Recently, block masonry retaining walls are being constructed because of the advantages of being relatively easy to construct using standardized blocks mass-produced and being able to create a variety of exposed appearances. The technology for constructing retaining walls using such blocks is disclosed in the following patent documents.

According to the 'natural retaining wall block' of 'Patent Document 1', 'it has multiple spaces penetrated vertically inside, and on both sides, concave-convex inserts that correspond to each other are formed, and on the rear end, it has a detachment prevention fixing jaw to prevent detachment from the embankment, and on the front, upper and lower surfaces, a vegetation space or a fishing gear for various animals or fish to enter and exit is formed, and when each retaining wall block is constructed closely, each insert is inserted into each other, so that the retaining wall block can be installed firmly, and since a vegetation opening or a fishing gear is formed between any retaining wall block and another retaining wall block adjacent vertically, when plants grow through this, it not only firmly supports the space between each retaining wall block, but also can implement a nature-friendly retaining wall, and can also serve as a resting place, spawning place, and shelter for small animals such as aquatic insects, amphibians, reptiles, and fish, thereby restoring or improving the natural ecosystem. 'It can be maintained.'

According to the 'reinforced soil retaining wall block' of 'Patent Document 2', 'the reinforced soil retaining wall block has a block body that is vertically stacked by having a drainage space section filled with gravel or crushed stone penetrated vertically and a laminated support assembly section formed on the outside of the drainage space section, and a laminated support pin section that is connected to the laminated support assembly section of one of the block bodies and inserted into the drainage space section and the laminated support assembly section of another block body that is laminated to one of the block bodies, thereby enabling the block bodies to be stacked in a row or stacked inwardly and overlappingly, thereby enabling the stacking form of the block bodies to be implemented in various ways, and the inward stacking distance of the block bodies can be easily adjusted.'

The 'vegetation block for building a retaining wall' of 'Patent Document 3' is 'a main body having a centrally formed hole with a predetermined width for inserting a fixed foot, and a connecting projection protruding from the bottom surface to a predetermined height so that the fixed foot can be installed, and a left and right step formed on the left and right of the connecting projection to prevent left-right shaking of the fixed foot, and a connecting groove formed on the lower part of the corresponding fixed foot to form a connecting means for bolt-connecting each other; left and right sides having the same inclination angle so that the front of the main body is longer than the rear, and an engaging projection having an arc-shaped contact surface is vertically formed on one side thereof, and an engaging groove having an arc-shaped contact surface is vertically formed on the other side; And, the main body of the vegetation block and the fixed feet to support the main body are separated to facilitate storage and movement, and at the same time, they can be easily combined on site to enable the construction of a stable retaining wall.'

In addition, the 'vegetation retaining wall block' of 'Patent Document 4' 'has a fan-shaped front part of the body of the block, a concave part symmetrical to the right side on the left side, a convex part symmetrical to the left side on the right side, a body protrusion formed on the upper surface of the front part of the body to prevent the blocks from sliding and soil runoff, two protrusions formed on the left and right rear surfaces of the upper surface of the body to prevent the blocks from sliding, a crescent-shaped space penetrating vertically in the front and a rectangular space in the rear are formed on the inside of the body, and a central groove is formed to connect the crescent-shaped space in the front and the rectangular space in the rear, thereby securing the integration of the blocks vertically, leftward, and rightward, thereby enhancing the stability of the slope and enabling rapid construction.'

According to the above prior arts, it can be seen that the structure is formed as a single whole in all directions, vertically, horizontally, and horizontally by interlocking the blocks, thereby actively preventing soil runoff from a cut or fill slope (or slope).

However, when the earth pressure generated by unexpected heavy rain is continuously applied to the blocks that make up the retaining wall, there is a problem of shearing or sliding between the weak blocks in the interlocking portion of the retaining wall. This problem causes rapid collapse of the retaining wall without any time to evacuate, resulting in human or material damage.

Therefore, there is an urgent need to develop retaining wall blocks that can minimize human or material damage by ensuring sufficient evacuation time by preventing sudden collapse when soil pressure is applied due to heavy rain.

KR Publication Number 10-2007-0017567 KR Registration No. 10-2485466 KR Registration No. 20-0371374 KR Publication Number 20-2011-0005277

The present invention is an improvement made to solve the problems of the above-mentioned prior art, and has an interlock structure that enables free rotation within a predetermined angle range on both the left and right sides of the block body, and a double anti-slip structure, thereby preventing sudden collapse when earth pressure is applied due to heavy rain, thereby securing evacuation time and thereby minimizing human or material damage, and providing stability. The purpose of the present invention is to provide an interlock block for constructing a retaining wall.

The purpose of the present invention is to provide an interlock block for constructing a retaining wall, which has a structure in which the upper and lower surfaces of the block body have different widths, thereby naturally forming a slope that is friendly to the surrounding environment during construction of the block.

The above object is achieved by an interlock block for constructing a retaining wall provided according to the present invention.

According to one aspect of the present invention, an interlock block for constructing a retaining wall comprises: a block body having a predetermined shape, which provides a reinforced soil-filled space with only the upper and lower portions open internally by front and rear walls and left and right walls that close all sides; an arch portion formed on the inner side of a rear wall portion of the block body positioned to be in contact with a slope of a cut site and forming a reinforcing structure that resists earth pressure; an inclined surface portion in which the upper surface area of the block body is made narrower than the lower surface area when forming the block body, and an inclination angle is formed at the front surface of the front wall portion as much as the angle narrows toward the upper portion of the block body, so that when constructing a retaining wall using the block body, a natural incline is formed over the entire height of the front portion of the retaining wall; An interlock rotation connection section formed on the left and right walls of the block body to interlock and connect adjacent block bodies, while connecting the interlocked block bodies to rotate within a predetermined angular range so that when earth pressure is applied, the interlock separation of the block bodies is delayed by the rotation time while suppressing it; and a sliding prevention section installed on the upper surface of the block body to support a portion of the stacked block bodies in a manner that catches them, thereby fixing and supporting the block bodies so that they do not slide forward in addition to delaying the separation of the block bodies by the interlock rotation connection section when earth pressure is applied.

The above interlock rotational connection includes a trapezoidal recessed portion as viewed from above provided by an angled protrusion formed across the entire height of one of the left and right walls of the block body, and an angled protrusion wall portion formed corresponding to the angled protrusion, the angled protrusion becoming narrower toward the inside and wider toward the outside, and the protrusion is characterized in that the rotation proceeds within the trapezoidal angular range of the recessed portion, but the rotation of the protrusion proceeds in a state in which it is restrained by the angle of the protrusion wall portion.

The above-mentioned anti-slip portion includes one or two fixing holes installed on both sides of the front and rear portions of the block body, and an anti-slip pin that is inserted so as to protrude from the fixing holes and fixes and supports the block body to be stacked by the protruding portion, and the anti-slip pin is characterized in that it fixes and supports only the inside of the rear lower portion of the reinforced soil filling space of the block body to be stacked, or fixes and supports the inside of the rear lower portion of the reinforced soil filling space of the block body and the lower front portion of the block body so as not to slide.

The above anti-push pin is characterized by being formed into a circular or square shape with a metal material and being inserted separately into the fixing hole.

The above block body is characterized by having a trapezoidal structure that is wide at the front and narrows toward the rear when viewed from above, and a rock decoration part is formed on the front surface of the front wall part and a drainage groove is formed in the center of the upper surface of the rear wall part.

According to the following embodiment of the present invention, the collapse of blocks is delayed when soil pressure is applied due to heavy rain, thereby providing an effect of securing sufficient evacuation time to minimize human or material damage.

In addition, the block according to the present invention provides the effect of forming a natural slope that is in harmony with the surrounding environment without wasting manpower and time.

Hereinafter, a preferred embodiment of the keyboard structure of an electronic keyboard musical instrument according to the present invention will be described in detail with reference to the attached drawings.

The present invention is susceptible to various modifications and may have various embodiments, and specific embodiments will be described in detail in the detailed description.

However, this is not intended to limit the present invention to specific embodiments, but should be understood to include all modifications, equivalents, or substitutes included in the spirit and technical scope of the present invention.

And in explaining the present invention, if it is judged that a detailed description of a related known technology may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, the terms described below are terms defined in consideration of their functions in the present invention, and thus may vary depending on the intention or custom of the user or operator, and therefore, the definitions should be made based on the contents of the entire specification explaining the present invention.

As shown in FIGS. 1(a)(b) to 4, an interlock block (100) for constructing a retaining wall according to the present invention includes a block body (110) formed of concrete that provides a reinforced soil filling space (112) with only the upper and lower parts open inside by front and rear wall parts (111-1, 111-2) and left and right wall parts (113-1, 113-2) that close all sides, and the block body (110) has a trapezoidal structure that is wide at the front when viewed from above and narrows toward the rear, so that a rock decoration part (114) that blends well with the surrounding natural environment is formed on the front surface of the front wall part, and a drainage groove (115) for drainage is formed in the center of the upper surface of the rear wall part (111-2). The reason why the above block body (110) is formed in a trapezoidal shape when viewed from above is to secure a fill space (S) between blocks (100) and blocks (100) when constructing a retaining wall by connecting the blocks as shown in FIG. 5 and FIG. 7(a) described below, and to further strengthen the support structure for fixing the blocks by cooperating with the reinforcing soil filled into the interior of the reinforcing soil fill space (112).

As shown in the drawing, an arch section (116) (see FIG. 2) extending to the adjacent left and right walls is formed on the inside of the rear wall section (111-2) positioned to be in contact with the cut slope of the block body (110) to form a reinforcing structure that is not easily damaged by the earth pressure that directly acts on the rear wall section (111-2) of each block (100) of the retaining wall constructed during heavy rain.

As shown in the drawings (Figs. 3 and 4), when the block body (110) is made of concrete, the upper surface area (W') is made narrower than the lower cross-sectional area (W), so that the front surface of the front wall portion (111-1) is formed with an angle of inclination (θ) that is as narrow as the upper surface of the block body (110). As shown in Fig. 6, when constructing a retaining wall using the block body (110), a natural slope portion (140) is formed over the entire height of the front surface of the retaining wall.

As shown in the drawing, an interlock rotational connection (120) is formed on the left and right walls (113-1, 113-2) of the block body (110) so as to interlock adjacent block bodies (110) and, when earth pressure is applied, the mutually connected block bodies (110) are rotated within a predetermined angle range so as to prevent or delay separation of the block bodies (110) from each other. This interlock rotational connection (120) includes an angled protrusion (121) formed over the entire height of one wall (113-1) among the left and right walls (113-1, 113-2) of the block body (110), and a trapezoidal recessed portion (122) formed on the other wall (113-2) corresponding to the angled protrusion (121) and becoming narrower toward the inside and wider toward the outside when viewed from above, and this recessed portion (122) is provided by the angled protrusion wall portion (123).

The interlock rotational connection (120) of this configuration allows the projection (121) to rotate freely within the angular range of the trapezoidal grooved portion (122), as shown in FIG. 7(a)(b) described below. However, the square projection (121) encounters the angled projection wall portion (123) while rotating in the grooved portion (122) (see FIG. 7(b)), and the rotation is temporarily prevented by the projection wall portion (123) and the angled projection (121) is delayed from easily detaching from the grooved portion (122).

As shown in the drawings (see FIGS. 1(a)(b) and 4), fixed holes (131) are installed in the front and rear sides of the upper surface of the block body (110), and anti-slip pins (132) are respectively installed to protrude in the fixed holes (131) to support the stacked block bodies (110) so that, in addition to preventing separation of the block bodies (110) by the interlock rotating connection (120) when earth pressure is applied, the block bodies (110) can be fixedly supported so that they do not slide forward (see FIG. 5). The fixed holes (131) and anti-slip pins (132) function as anti-slip members (130) that exert a fixed supporting force to prevent the stacked block bodies (110) from being easily separated and pushed due to earth pressure, as shown in FIG. 5 described below. The above protruding pin (132) is formed into a circular or square shape with a metal material that maintains strength that is not easily broken or bent, and is inserted separately into the fixing hole (131).

In the drawing, two fixing holes are installed on each side of the front of the upper surface of the block body (110) and one fixing hole is installed on each side of the rear, but two may be installed on the rear and one may be installed on the front, and if the strength of the block body is secured, two fixing holes may be installed on each side of the front and rear.

An example of the construction of an interlock block (100) for constructing a retaining wall according to the present invention configured in this manner is described with reference to Fig. 5. Fig. 5 is a drawing showing a portion of a retaining wall constructed using an interlock block for constructing a retaining wall according to the present invention as viewed from the front.

As shown in the drawing, when constructing a retaining wall by stacking blocks (100) of the present invention from the foundation of a cut site, the blocks (100) that are adjacently arranged to be stacked are connected in a state where the interlock rotational connection parts (120) of the left and right wall parts (113-1, 113-2) of the block body (110) are loosely fitted into the trapezoidal grooved part (122), thereby interlocking the block bodies (110) and causing the protrusions (121) to rotate within the groove angle range of the trapezoidal grooved part (122) when earth pressure is applied, for example, due to heavy rain, so that rapid separation of the block bodies (110) can be prevented or delayed.

An example of the working day for this is shown in Fig. 7(a)(b), respectively. Fig. 7(a)(b) is a drawing showing the working state between interlock blocks when earth pressure acts on a retaining wall constructed using interlock blocks for retaining wall construction according to the present invention.

As shown in the drawing, the block (100) of the present invention is connected so that the adjacent block bodies (110) are interlocked by loosely fitting the square protrusions (121) into the trapezoidal grooves (122) having the square protrusions (123) so that the block bodies (110) are interlocked, but the square protrusions (121) are connected so as to rotate within the groove angle range of the trapezoidal grooves (122). By means of the interlock rotational connection (120) (see Fig. 7(a)), when the earth pressure is applied, the interlocked block bodies (110) are interlocked so that the square protrusions (121) rotate by an amount corresponding to the width range of the grooves with the trapezoidal grooves (122) as the support point, and further, when the rotation progresses, the square protrusions (121) By forming a structure that suppresses and delays the rotation speed by making it hooked on the angled protrusion wall portion (123) that provides the groove portion (122), the interlocked block body (110) has the effect of suppressing and delaying easy separation.

The resistance to earth pressure of these blocks (100) is also aided by the reinforcing structure of the arch portion (116) that extends to the inner side of the rear wall portion (111-2) positioned in contact with the cut slope of the block body (110) and the adjacent left and right walls.

Therefore, it minimizes human or material damage due to sudden separation when earth pressure is applied to a block in the past (see FIGS. 9(a)(b)(c)). FIGS. 9(a)(b)(c) are drawings showing examples of block action when earth pressure is applied to an existing retaining wall in the past (including special documents 1 and 2). Looking at this block (10), the interlock part (20) only has an interlock structure without providing a rotation angle, so there is a concern that when earth pressure is applied, the interlock part (20) may separate at a high speed, causing a lot of damage. However, the present invention provides the benefit of resolving this problem.

In addition, the stacking of blocks of the present invention can be installed in a state where the block bodies (110) in which both ends of the stacked blocks (100) are interlocked with each other in a bridge shape are caught on the protruding pin (132) on the rear side forming the anti-slip part (130), as shown in FIG. 5.

The reason for installing in this way is that the protruding pin (132) protruding from the upper surface of the block body (110) is positioned so as to be caught by the lower inner side of the reinforcing soil filling space (112) of the stacked block body (110), thereby forming a structure in which the stacked block bodies (110) are connected to each other as one piece, thereby reinforcing the resistance to earth pressure, like the interlock rotational connection (120) (see FIG. 7(a)).

In addition, when the block bodies (110) to be laminated are laminated in a state where they are caught by the protruding pin (132) installed on the rear side protruding from the upper surface of the block bodies (110) arranged at the bottom, the front wall portion (111-1) forming the angle of inclination (θ) as shown in Fig. 4 is laminated in a state where it naturally matches, thereby naturally forming an inclined surface portion (140) over the entire height of the front portion of the retaining wall, thereby showing that it is possible to achieve natural harmony with the surrounding natural environment.

Fig. 8 is a drawing showing another example of the construction of a retaining wall constructed using an interlock block for constructing a retaining wall according to the present invention. Parts identical to those in the above embodiment are indicated by the same reference numerals to avoid duplicate explanation.

As shown in the drawing, unlike the embodiment of the above-described FIG. 5, in this embodiment, the inside of the rear lower portion of the reinforced soil filling space (112) of the stacked block bodies (110) is fixedly supported by being caught by anti-slip pins (132) protruding from the block bodies (110) already arranged on the lower side, and also the front portions on both sides of the lower portion of the stacked block bodies (110) are fixedly supported by being caught and stopped by anti-slip pins (132) protruding from the upper front surface of the block bodies (110) already arranged on the lower side so as not to be pushed forward. This means that the stacked block bodies (110) are fixedly supported in a state of being caught from both the front and rear sides so as not to be pushed due to the earth pressure of the constructed retaining wall blocks, thereby providing a double reinforcement structure. Since the other configurations and functions are all the same as the above-described embodiment, a separate description is omitted.

Although the present invention has been described in detail through specific embodiments, this is only for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and all simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be made clear by the appended claims.

A retaining wall constructed using blocks according to the present invention can minimize damage to life or property by eliminating the risk of sudden collapse even in heavy rain.
