Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stiffener member and a reinforcing member assembly including the stiffener member.

The present invention relates to a stiffener, and more particularly, to a stiffener and a stiffener assembly for reinforcing a tensile strength of a ground by one end being fixed to a reinforcing block and the other end being installed in a backfill soil.

A block-type retaining wall structure formed by stacking a plurality of blocks is constructed in order to prevent the soil from flowing down and collapsing at the banks, mountainside, and the like. In such a reinforced earth retaining wall, a reinforcing material for bonding the retaining wall block to the backing soil (reinforcing soil body) is generally used.

Geogrid, which is a kind of reinforcing material, is a geogrid in the form of a net. Recently, it has been known that a stiffener which is installed in a fitting groove formed on the upper surface of a retaining wall block assembled on the front surface of a reinforced earth retaining wall, Is used.

That is, in order to reinforce the tensile strength of the ground in a stacked block, a band-shaped fiber reinforcing material is installed. The fiber reinforcing material is fixed to a block at one end using an anchor or an anchor pin and the other end is buried long in the ground And forms a reinforcing body to resist an external force such as earth pressure.

In the case of supporting a block forming the retaining wall by using such a band-shaped fiber reinforcing member, a band-shaped fiber reinforcing member is hooked to a connecting ring protruding from the front end of the band-shaped fiber reinforcing member to the back surface of the block, The other end of the band-shaped fiber reinforcing member having one end hooked to the link is hooked on a support rod fixed to the front side, and the reinforcing soil is filled between the block and the support wall to form a retaining wall structure.

However, such a fiber reinforcing material has insufficient frictional resistance with soil, and in many cases, the length of the reinforcing material is increased more than necessary when the stability is examined. Of course, it is possible to increase the friction resistance by extending the length of the fiber reinforcing material, but this increases disadvantage in terms of workability and economical efficiency.

In addition, a technique for fixing a fiber reinforcing material is used in which a fiber reinforcing material is wound between blocks constituting a retaining wall so as to be pressed and fixed to the weight of the block. However, when the blocks are opened, the fiber reinforcing material easily escapes, There was also a problem to reduce.

In order to compensate for these drawbacks, non-conductive materials such as steel are sometimes used as reinforcing materials. The stiffener made of steel has a passive resistance at its rear end to increase the frictional resistance, and is advantageous in the passive resistance performance as compared with the fibrous reinforcement in terms of the characteristics of the steel.

However, the metal reinforcement material such as steel has a disadvantage in that the material cost is greatly increased and the workability is relatively low, for example, a manual resistor is required.

FIG. 1 is a cross-sectional view of a preferred embodiment of a stiffener assembly including a strip-shaped stiffener according to the present invention, and FIG. 2 is a plan view of the structure of an embodiment of the present invention.

As described above, the reinforcement block 100 installed on the entire surface of the reinforced earth retaining wall to be constructed forms the skeleton and the exterior of the reinforcement block assembly according to the present invention. The reinforcing block 100 is accumulated in front of the backbone soil B, and FIG. 1 shows one of the accumulated reinforcing blocks 100.

The block body 110 of the reinforcing block 100 may be formed in various shapes. In this embodiment, as shown in FIGS. 2 and 3, the block body 110 is formed to be bilaterally symmetrical. Of course, the cross-sectional surface of the block body 110 of the reinforcing block 100 may be formed in a polygonal shape such as a square, a hexagon, or a circular shape.

A storage space 130 is formed in the reinforcing block 100. The storage space 130 is formed at one side of the reinforcing block 100. The storage space 130 has a fixing piece 300 to be described later. The storage space 130 is formed in a shape corresponding to the stationary piece 300 so that the stationary piece 300 can be inserted into the storage space 130 without any clearance and thereby the stiffener 200, The stiffener 200 can be firmly fixed through the frictional resistance between the reinforcing block 100 and the reinforcing block 100.

As shown in FIGS. 2 and 3, the seating part 120 is formed to extend from one side of the storage space 130. The seating part 120 is formed on the upper surface of the reinforcing block 100 and the strip base 210 of the stiffener 200 to be described below is seated on the seating part 120.

The seating part 120 is provided with a locking boss 150. The latching boss 150 protrudes from the seating portion 120 and is a portion where one of the resistance means 250 of the band-shaped stiffener 200 to be described below is hooked. In this embodiment, the locking boss 150 may have a cylindrical shape, and various modifications may be made as long as the locking boss 150 protrudes from the seating portion 120.

In the present embodiment, the storage space 130, the seating portion 120, and the locking boss 150 are formed as a pair on the left and right sides of the reinforcing block 100, but the present invention is not limited thereto. The space 130, the seating part 120, and the locking boss 150 may be provided one by one or three or more. More precisely, the receiving space 130, the seating part 120, and the locking boss 150 may be formed in various numbers and shapes to correspond to the configuration of the band-shaped stiffener 200.

As shown in FIG. 1, a guide surface 180 is formed at the end of the seating part 120 corresponding to the rear edge of the reinforcing block 100. A portion of the strip base 210 of the band-shaped stiffener 200 to be described below is seated on the guide surface 180. The guide surface 180 is formed in a shape of a curved surface or an edge of the reinforcing block 100, .

Even if a shearing load is applied to a portion where the reinforcing block 100 contacts the belt-shaped stiffener 200 due to the sinking of the reinforcing soil or the like, the belt-shaped stiffener 200 is seated on the guide surface 180 formed of a curved surface or an inclined surface It is possible to prevent the belt-like stiffener 200 from being shearly fractured by the earth pressure and the edge portion of the reinforcing block 100.

The stiffener 200 extends rearward of the reinforcing block 100 and the reinforcing block 100. The stiffener 200 is installed in the backbone soil B and serves to reduce the earth pressure that the backbuffer soil B is required to transversely change through the friction force with the backbuffer soil B. [ More precisely, by reducing the earth pressure by the friction between the backfill soil B and the strip-like stiffener 200, the adhesion force and the internal friction angle of the backfill soil B are improved and the shear strength of the backfill soil B is improved So that a firm reinforcing soil can be obtained.

The band-shaped stiffener 200 is formed in a thin strip shape, and is basically made of a flexible material. In this embodiment, the band-shaped stiffener 200 is made of a fiber material. For example, the band-shaped stiffener 200 may be made of a polymer material, or may be formed by covering a high-strength polyester fiber or a polyethylene sheath. Of course, the band-shaped stiffener 200 need not be limited to a fiber material but may be made of various materials having high tensile strength.

The stiffener 200 is fixed to the seating part 120 of the reinforcing block 100 and can be easily fixed to the reinforcing block 100 through the fixing piece 300 to be described later. The fixing of the stiffener 200 will be described below.

Fig. 4 shows a first embodiment of the strip-shaped stiffener 200. Fig. As shown in the figure, the strip type stiffener 200 includes a strip base 210 extending in one direction and a resistance unit 250 provided in the strip base 210. The strip base 210 and the resistance means 250 are each made of a flexible material, and they may be the same material or different materials.

The strip base 210 has a flat strip shape and extends in one direction. In the first embodiment, the strip bases 210 are formed of a pair of spaced apart from each other. That is, the strip base 210 is composed of a first strip and a second strip.

The resistance unit 250 connected to the strip base 210 may protrude from either the upper surface or the lower surface of the strip base 210. In the embodiment shown in FIG. 4, . The resistance means 250 protrudes in a direction orthogonal to a direction in which the strip base 210 extends, thereby increasing the frictional resistance of the passive resistance between the body and the stiffener 200.

A plurality of resistance units 250 are provided along the longitudinal direction of the strip base 210, only a part of which is shown in FIG. A plurality of resistance means 250 are provided along the longitudinal direction of the strip base 210 to increase frictional resistance by the strip type stiffener 200.

The resistance means 250 further includes a pair of connection portions 252 connected to an outer surface of the strip base 210 and a resistance portion 255 positioned between the connection portions 252. The connection unit 252 connects the strip base 210 and the resistance unit 250 and is connected to the strip base 210 using a separate material such as an adhesive or a fastener 350, The connection portion 252 may be formed integrally with the strip base 210 to be naturally connected.

The resistor unit 255 is provided between the connection units 252 and protrudes from the strip base 210 to substantially increase the frictional resistance. As shown in FIG. 4, the resistive part 255 extends upward from the strip base 210 in an inclined direction. This is for maximizing the frictional resistance by the resistive part 255, more precisely the resistive part 255 is inclined upwardly toward the reinforcing block 100. Accordingly, in the process of pulling the strip-shaped stiffener 200 toward the reinforcing block 100 by the earth pressure or the like, the back-filling soil B is further inserted into the inside of the resistance portion 255 to increase the resistance.

In this embodiment, the resistance portion 255 is curved between the connection portions 252. More precisely, the resistance portion 255 is formed as a continuous curved surface extending from the center of the protrusion to the connection portion 252.

Next, referring to Fig. 5, a second embodiment of the strip-like stiffener 200 is shown in Fig. As described above, the strip base 210 constituting the strip-shaped stiffener 200 may be constituted by one flat member. That is, the strip base 210 is not formed as a pair, but is formed of a thin and flat member, and the connection portions 252 are connected to the left and right end portions of the strip base 210, respectively.

A plurality of resistors 255 are provided between the connection portions 252 along the longitudinal direction of the strip base 210. Although not shown, a plurality of penetrating portions may be provided at corresponding positions between the resistive portions 255 of the strip base 210 so that the gravel may pass through the resistive portions 255.

Fig. 6 shows a third embodiment of the strip-like stiffener 200. Fig. As described above, some of the resistor units 250 provided along the strip base 210 extend in a direction inclined toward one side of the resistor unit 255, and a part of the resistor unit 255 extends in the opposite direction Lt; / RTI >

Accordingly, the band-shaped stiffener 200 is configured to be symmetrical in both directions to have a non-directional structure. This enhances the resistance both in the direction toward the retaining wall and in the opposite direction, so that the band-shaped stiffener 200 can be applied to various environments and structures.

In this embodiment, the resistance unit 250 in which the resistance unit 255 extends in a direction inclined toward one side and the resistance unit 250 in which the resistance unit 255 extends in an inclined direction toward the other, Are sequentially provided one by one along the base 210 in a staggered manner. It is needless to say that the resistance means 250 having different directions are not necessarily provided one by one, but may be provided in plural.

Fig. 7 shows a fourth embodiment of the band-shaped stiffener 200. Fig. As shown in the figure, a resistance pocket (P) is formed in the resistance means (250) of the band-shaped stiffener (200). More precisely, a resistance pocket (P) opened in one direction is formed in the resistance portion (255) of the resistance means (250). The resistance pockets P may be formed by extending the resistive portions 255 above and below the strip base 210, respectively.

The resistance pockets P serve to increase the area of friction between the resistive part 255 and the gravel and consequently to increase the frictional force between the band-shaped stiffener 200 and the backfill soil B. In this embodiment, the resistance pockets P are elongated in the left and right direction. However, the resistance pockets P are not necessarily limited to this, and the resistor pockets P may extend relatively longer in the vertical direction.

8, the resistor unit 255 includes a first resistor pocket P1 opened in one direction parallel to the longitudinal direction of the strip base 210, and a second resistor pocket P1 opened in the other direction And a second resistance pocket P2 may be provided, respectively.

Accordingly, the band-shaped stiffener 200 is configured to be symmetrical in both directions to have a non-directional structure. This enhances the resistance both in the direction toward the retaining wall and in the opposite direction, so that the band-shaped stiffener 200 can be applied to various environments and structures.

Fig. 9 shows a sixth embodiment of the strip-shaped stiffener 200. Fig. As described above, the strip-shaped stiffener 200 is provided with a resistance portion 255 between the connection portions 252 at both ends thereof, and the resistance portion 255 is inclined to both sides with respect to the longitudinal direction of the strip- Respectively.

In this embodiment, the inclined surface of the resistance portion 255 increases the frictional force with the soil and is symmetrical in both directions, so that it has a non-directional structure.

Of course, as in the seventh embodiment shown in FIG. 10, one side of the resistor portion 255 may extend in a direction orthogonal to the strip base 210.

Fig. 11 shows an eighth embodiment of the strip-like stiffener 200. Fig. The strip type stiffener 200 includes a pair of strip bases 210, a connection portion 252 connected to the strip base 210, and a resistance portion 255 between the connection portions 252 .

The resistor unit 255 extends in a direction orthogonal to the strip base 210 and the connection unit 252 has a symmetrical shape extending on both sides of the longitudinal direction of the strip base 210 . Accordingly, the band-shaped stiffener 200 is configured to be symmetrical in both directions to have a non-directional structure.

Although not shown, three or more strip bases 210 constituting the strip-shaped stiffener 200 may be spaced apart from one another, and a part of the resistance means 250 provided in the strip- And some of them protrude downward.

12 shows the configuration of the stationary piece 300 constituting the embodiment of the present invention. As described above, the fixing piece 300 inserted into the receiving space 130 of the reinforcing block 100 is composed of a substantially hexahedral piece body. Of course, the piece body 310 is not limited to the hexahedron shape, and may have various shapes corresponding to the shape of the receiving space 130.

A fixing slot 320 is formed in the fixing piece 300. The fixing slot 320 is a portion into which a part of the band-shaped stiffener 200 is inserted, and a part of the fixing piece 300 is opened. That is, by inserting the strip base 210 of the strip-shaped stiffener 200 into the fixing slot 320, the strip-shaped stiffener 200 can be fixed to the fixed piece 300.

In this embodiment, the fixed slots 320 are formed of a first slot 330 and a second slot 340 spaced from each other. The first slot 330 and the second slot 340 are formed to penetrate the fixing piece 300 so that one end of the strip base 210 of the strip type stiffener 200 is inserted into the first slot 330, And then protrude in the opposite direction through the second slot 340 and be fixed.

1, a fastener 350 is inserted into the fixing piece 300 in a direction orthogonal to a direction in which the fixing slot 320 is opened. The fastener 350 is assembled to the fastening piece 300 to narrow the width of the fastening slot 320, thereby pressing one end of the inserted stiffener 200. Of course, two or more fasteners 350 may be provided on the fixing piece 300. Reference numeral 345 denotes a fastening hole into which the fastening tool 350 is inserted.

Hereinafter, a process of constructing the stiffener assembly including the strip-shaped stiffener according to the present invention will be described.

First, the worker picks up the ground surface of the place where the retaining wall is to be constructed, and then, places the reinforcing block 100 thereon. The reinforcing block 100 may be extended in one direction so that a plurality of the reinforcing blocks 100 are adjacent to each other. Backing soil B is installed on the backside of the reinforcing block 100.

Then, the worker installs the strip-shaped stiffener 200 prior to accumulating the reinforcing block 100. The stiffener 200 may be positioned between the reinforcing blocks 100 to be stored. In the present invention, the stiffener 200 is fixed to the reinforcing block 100 through the fixing pieces 300.

More precisely, the band-shaped stiffener 200 protrudes through the second slot 340 after one end of the band-shaped stiffener 200 is inserted into and passed through the first slot 330 of the fixing piece 300. A fastener 350 is assembled to the fixing piece 300 to narrow the width of the fixing slot 320. In this process, the band-shaped stiffener 200 is pressed and fixed in the fixing slot 320 .

In this state, the worker inserts the fixing piece 300 into the receiving space 130 of the reinforcing block 100. Since the storage space 130 is open at one side, the fixing piece 300 can be easily inserted into the fixing space 300, and one end of the fixing piece 300 and the strip-shaped stiffener 200 connected thereto is naturally fixed. Therefore, the worker does not need to wrap the reinforcing block 100 to fix the strip-shaped stiffener 200 to the reinforcing block 100.

At the same time, the band-shaped stiffener 200 is seated on the seating part 120 recessed on the upper part of the reinforcing block 100. The strip base 210 of the strip-shaped stiffener 200 is seated on the seating part 120 and extends in the direction of the backside soil B in the rear direction.

At this time, one of the resistance means 250 of the band-shaped stiffener 200 is hooked on the engagement boss 150 of the reinforcing block 100. 1 and 2, the resistance means 250 located relatively forward of the plurality of resistance means 250 provided on the band-shaped stiffener 200 is hooked on the engagement boss 150, .

Another reinforcing block 100 is accumulated on the upper portion of the reinforcing block 100 and a new backing soil B is installed on the backside of the reinforcing block 100 to cover the upper portion of the staple- .

Then, the above-described process is repeated to continue the construction of the stiffener assembly. As described above, according to the present invention, the operation of winding a part of the strip-shaped stiffener 200 on the structure is omitted, and the operation of inserting the stationary piece 300 having one end of the strip-shaped stiffener 200 fixed to the reinforcing block 100 The stiffener 200 can be easily installed.

Particularly, the strip-shaped stiffener 200 is improved in the pull-out resistance due to the presence of the resistance means 250, so that it is not necessary that one end of the strip-shaped stiffener 200 is installed in a staggered manner in the back- 200) itself is shortened, and the length of the backfill soil (B) and the amount of excavated soil are also decreased.

Thus, when the strip-shaped stiffener 200 is installed, the backfill soil B becomes a reinforcing soil, and the stability is improved. More precisely, the band-shaped stiffener 200 improves the adhesion force and the internal friction angle of the backbone soil B by reducing the earth pressure through friction with the backbone soil B by the material itself, 250) further increases the passive resistance frictional force.

That is, since the resistance means 250 is provided along the longitudinal direction of the strip-like stiffener 200, the passive resistance of the strip-shaped stiffener 200 and the pull-out resistance capability are largely formed, thereby improving the stability of the reinforced earth retaining wall.

For example, in the case where the earth pressure to which the backfill soil B is to be transversely changed due to a natural environment or a special external environment is greatly generated, the retaining wall formed by the reinforcing block 100 is subjected to an external force, The stiffener 200 connected to the reinforcing block 100 is also subjected to a force pulled outward.

However, the strip-shaped stiffener 200 according to the present invention is provided with the resistance means 250 and has a large frictional force with the backfill soil B, and this frictional force is generated by the stiffener 200 in the reinforcing block 100 The larger the force is received in the direction of the retaining wall. Accordingly, the pull-out resistance of the strip-shaped stiffener 200 is greatly improved, and the retaining wall can be stably maintained. Accordingly, the inclination angle of the retaining wall can also be designed to be relatively large.

Since the guide surface 180 is formed at a portion where the stiffener 200 and the reinforcing block 100 are in contact with each other, settlement of the reinforcing soil occurs and a shear load is applied to the portion where the stiffener 200 contacts the reinforcing block 100 The stiffener 200 is seated on the guide surface 180 formed by a curved surface or an inclined surface so that the stiffener 200 is prevented from being shearly broken by the reinforcing block 100.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
