Retaining Wall Pressing Device capable of adjusting and fixing angles {Angle Adjustable and Fixed Retaining Wall Pressing Device}

The present invention relates to a retaining wall crimping device capable of adjusting and fixing the angle, and adjusts the bonding angle of the retaining wall in accordance with the installation angle of the tension member installed on the inclined surface of the cut, fixes it, and compresses the tensile material to a strong binding to the retaining wall. It is about.

In more detail, the retaining wall crimping device capable of adjusting and fixing the angle of the present invention is provided with a central tube body for receiving a tensile material in a precast panel installed as a retaining wall as a cut slope reinforcement member, and accommodates the central tube body in the center. The crimping section is provided with a backboard and is crimped and fixed to the precast panel, and a dome-shaped crimping dome is provided on the front surface of the crimping section to maintain a stable fixed bonding state by dispersing pressure, and at the same time, a crimping bonding hole and a dome in the form of a long hole formed in a number of domes A plurality of fastening coupling holes formed in the form of a long hole correspond to each other on the fastening portion that can move along the surface of the fastener, and can be fixed according to the rotational close movement of the pressing portion and the fastening portion even if the tension member and the center tube do not form a horizontal angle, When the tension material is an anchor, the anchor wire and the anchor wire Turning relates to a retaining wall, a compression bonding device capable of adjusting and fixing the angle, characterized in that it can proceed up to a tensile action, if at all affected.

In general, a retaining wall is used as a method of reinforcing a slope to prevent the collapse of a cut part during construction of a road, a building, or the like.

The method in which the retaining wall is installed is first, when a hole is formed using a drilling device on the inclined surface of the cut, an anchor composed of a nail such as a rock bolt, a rebar, or a steel wire is inserted into the hole to be used as a tensile material.

Subsequently, the grouting solution is injected into the perforation hole, so that the tensile material is firmly fixed in the inclined surface of the cut portion while undergoing a curing process.

At this time, the tensile material is generally inclined at a constant angle to the inclined surface of the cut portion and has a shape inclined at a predetermined angle without being level with the ground.

On the other hand, the retaining wall installed perpendicular to the ground has a form in which the connecting device coupled with the tension member is horizontal or has an angle close to horizontal.

In this case, when the retaining wall connecting device is horizontal, additional work is required to artificially change the angle of the tensile material, which increases the time and cost, as well as the strength and fixing force of the tensile material is significantly reduced, which can cause serious problems in safety. There is a great risk of deterioration in durability.

Accordingly, a retaining wall connecting device bent at a predetermined angle has been developed and used, but since it is manufactured at a factory and provided for construction in the field, the tensile material that is installed and inserted according to various field situations does not exactly match the angle, so it is a reinforcing bar that is a tensile material. It is deformed by applying an external force to the product, or the steel wire is bent and the design tensile force cannot be secured, and a gap occurs in the joint part, which greatly reduces the fixing force and durability between the tension member and the retaining wall, which greatly increases the risk of safety accidents. would.

In addition, once the construction is completed, it is very difficult to safely and quickly take action while maintaining the existing fixed condition even if additional conditions are needed to change the conditions of the site or re-tension the tension. The situation has a problem of labor and cost.

In particular, in the case of an anchor in which a wire of a stranded wire is used, there is a factor in which additional tension must be applied to re-tension the anchor after a certain period of time since construction. Despite this, the situation is causing inefficiencies and safety accidents that entail large-scale reinforcement work.

The retaining wall crimping device 10 capable of adjusting and fixing the angle according to an embodiment of the present invention includes a precast panel 100, a center tube 200, a crimping portion 300, a tightening portion 400, and an anchor portion ( 500) and an installation space part 600.

The precast panel 100 is composed of a unit that forms a retaining wall, and the precast panel 100, the crimping unit 300, and the central tube 200 are manufactured at a factory and supplied to the site while being combined.

In the central portion of the precast panel 100, an installation space portion 600 configured in the form of a recess is formed toward the center from one side.

The central tube 200 having a through hole formed therein may be provided in a shape that penetrates from the other side of the precast to the installation space part 600 and connects to the crimping part 300 located in the installation space part 600. .

The central tube 200 functions as a passage for receiving the tension member 20 such as a rock bolt, nail, anchor, etc., and may be formed to penetrate through the precast panel 100 at an angle.

This is because the retaining wall, which is inserted into the inclined surface of the cut portion, is installed in an inclined shape with a predetermined angle with the ground, such as a rock bolt, nail, anchor, etc., and the retaining wall that engages with the tension member 20 is perpendicular to the ground. to be.

The central tube 200 may be configured with a diameter that can sufficiently accommodate rock bolts, nails, anchors, etc., which are generally used in the construction of retaining walls.

This is a general recommendation criterion, even if the tensile material 20 is inserted into the cut surface of the cut, and the precast panel 100 and the center tube 200 are manufactured and supplied to the site accordingly, various construction conditions exist. This is because it is impossible to accurately match the inclined angle between the tension member 20 and the center tube 200.

Therefore, in accordance with the construction standards, the center tube 200 is inclined to be manufactured, but the diameter of the center tube 200 is tensioned so that the tensile material 20 constructed in the field can be sufficiently accommodated therein even though the angle is different from the center tube 200. 20) It can be made larger.

The central tube 200 may be exposed to the installation space part 600 and combined with the compression part 300.

A central hole 330 may be provided as a through hole formed such that the center tube 200 is in close contact with the center of the compression unit 300.

The crimping portion 300 serves to securely fix the central pipe 200 to the precast panel 100 within the installation space portion 600 while accommodating the central pipe 200 in the crimping central hole 330. .

To this end, the compression unit 300 may include a backboard 310, a compression dome 320, and a compression bonding hole 321.

The backboard 310 is a plate-shaped member contacting the inner surface of the precast panel 100, and a compression center hole 330 is formed in the center, while the center tube 200 is tightly received and accommodated in the precast panel 100. It functions as a strongly fixed area.

The crimping dome 320 is provided with a central portion protruding in the shape of a dome, and the rims excluding the protruding portions are in contact with the back board 310 as a plate shape.

That is, the back board 310 and the crimping dome 320 have a shape in which the rim is in contact with the rim, and the central portion of the crimping dome 320 has a convex shape.

Each center surface of the back board 310 and the crimping dome 320 is provided with a crimping center hole 330, and a space between the back board 310 and the crimping dome 320 is connected to the crimping center hole 330. Virtual passages can be constructed.

The center tube 200 may be connected to the center of the crimp portion 300 along the crimp central hole 330.

A crimping column 350 may be provided between the backboard 310 and the crimping dome 320 for fixing and supporting the central tube body 200.

The crimping column 350 is a through-hole tube connecting the center of the backboard 310 and the crimping dome 320, and is formed so that the center tube 200 is tightly accommodated on the inner circumferential surface.

Accordingly, a crimp space 340, which is an internal space excluding the backboard 310, the crimp dome 320, and the crimp column 350, may be formed inside the crimp section 300.

The crimping unit 300 compresses the precast panel 100 with the back board 310 provided on one side, thereby reducing and dispersing the tensile stress, and partially dividing the tensile stress transmitted to the precast panel 100 To reduce the harmful effects such as the occurrence of cracks in the precast panel 100, the fastening part 400 to be described later through the crimping dome 320 provided on the other side smoothly adjusts the binding angle with the tension member 20 to be combined Make it possible.

The crimping dome 320 may be provided with crimping coupling holes 321 that are formed in a long hole shape along the circumference of the dome.

The crimping hole 321 has a shape of a long hole that connects the outer side of the crimping dome 320 and the crimping space 340 inside the crimping portion 300.

The fixing bolt 360 provided in the compression bonding hole 321 may be provided to be movable along the compression bonding hole 321.

The fixing bolt 360 penetrates the crimp coupling hole 321 and is provided over the outside of the crimp space 340 and the crimp dome 320, and moves along the crimp coupling hole 321 to fasten the part 400 to be described later. It is bound.

The head of the fixing bolt 360 is located in the crimping space 340, so the fixing bolt 360 is not lost to the outside of the crimping portion 300 even when the fastening portion 400 is not bound, and the crimping coupling hole 321 ).

Since there is a crimping space 340 maintained as a space inside the crimping portion 300, the fixing bolt 360 adjusts for the bonding angle with the tensile material 20 at the time of initial construction and later of the tensile material 20 at the time of reinforcement construction. In any case, such as when adjusting the position for re-tension, it is possible to smoothly change the position and perform the role of binding and fixing.

On the other hand, a plurality of binding members 331 may be provided on the rim where the back board 310 and the crimping dome 320 come into contact with each other for fixing and fixing the state.

The binding member 331 can be manufactured so as not to be deformed by strongly binding the backboard 310 and the crimping dome 320 and being embedded in the precast panel 100 to fix its shape.

In the conventional retaining wall crimping device, since the backboard 310 is not provided as in the present invention, after a crimping device such as a crimping dome 320 is connected to the tension member 20, the crimping device and the tension member 20 The space was filled with solid materials such as concrete.

Therefore, in the conventional construction, once the tension member 20 is connected to the retaining wall crimping device and the fixing work with the fixing bolt 360 is completed, further adjustment work is impossible in the state filled with concrete.

This makes it very difficult to combine the tension member 20 and the retaining wall crimping device with the adjustment of the angle, and in some cases, an artificial external force is applied to the tension member 20 to cause the deformation of the angle, and thus the connection is forced. , As the strength of the tensile material 20 is lowered and acts as a factor inhibiting the durability of the retaining wall installation, it will have a risk in safety accidents.

On the other hand, the backboard 310 has a plate-shaped square shape, forms a backboard 310 and a crimping space 340, and the crimping dome 320 connected to the front is combined by matching the center portion in the shape of a dome. By dispersing the force and distributing the pressure properly, it can function to increase the robustness and durability of the retaining wall.

That is, the rectangular panel formed by the backboard 310 uniformly distributes the tensile stress corresponding to the pulling force of the tension member 20 to each direction of the back side of the compression unit 300, and the round surface formed by the female dome is the tension member 20 It can function to evenly distribute the pressure that is fixed to the retaining wall crimping device by pulling.

In this way, the crimping unit 300 corrects the misalignment angle between the tensile material 20 and the retaining wall crimping device accommodating the tensile material 20, naturally accommodates it and maintains a fixed state, and the tensile stress generated by the tensile material 20 Is distributed evenly over the entire retaining wall through a crimping device to significantly improve safety.

On the other hand, in the crimping portion 300, the back board 310 has a certain shape as a square plate shape, and the crimped dome 320 coupled thereto is formed in such a way that a portion formed round like a dome protrudes outward of the back board 310. It may be configured, or may be configured to be settled inward toward the backboard 310.

Through this, the retaining wall crimping device may be used to comprehensively consider the situation by site where the retaining wall is installed, the size of the retaining wall, and the load applied to the retaining wall, so that a suitable type of crimping unit 300 can be selected and constructed.

On the other hand, if the compression unit 300 is made to preferentially combine with the tensile material 20 by matching the angle between the tensile material 20 and the retaining wall crimping device 10 capable of adjusting and fixing the angle of the present invention, then the combined It is necessary to keep the angle tightly.

To this end, the retaining wall crimping device 10 capable of adjusting and fixing an angle according to an embodiment of the present invention may include a fastening part 400.

The fastening part 400 is configured to be in close contact with the surface of the crimping dome 320, and can be rotated along the surface of the crimping dome 320, and is fixed by a fixing bolt 360 provided in the crimping portion 300. It can be bound and fixed with the crimping dome 320.

Therefore, the fastening part 400 may include a fastening body 410, a fastening center hole 411, a fastening coupling hole 412, and a fixing nut 420.

The tightening body 410 is in close contact with the crimping dome 320 and performs a function of moving and joining.

One end of the tightening body 410 is directed toward the outer surface of the installation space portion 600, or may be configured in a plate-like shape or a central portion protruding stepwise.

The other end of the tightening body 410 is configured as a shape corresponding to the crimping dome 320, and the tightening body 410 along the surface of the crimping dome 320 may be provided to move as if sliding.

Therefore, when the crimped dome 320 is in the form of a protruding dome, the other end of the tightening body 410 has a settled form in the form of a dome, whereas, when the crimped dome 320 has a settled dome, The other end of the tightening body 410 has the shape of a protruding dome.

A fastening central hole 411 may be formed in the center of the fastening body 410 in the form of a through hole.

The fastening central hole 411 is configured to face the crimp central hole 330 and accommodate the tensile material 20, and may be provided to have a shape in which the tensile material 20 is in close contact with the inner circumferential surface.

As a result, the tension member 20 is coupled to the inside of the precast panel 100 while being drawn into the central tube 200, and the compression center hole 330 of the compression section 300 and the compression center hole 411 of the fastening section 400 ) To have a shape leading to the installation space 600.

The fastening coupling hole 412 may be provided as a number of long holes formed along the periphery of the fastening central hole 411.

The fastening coupling hole 412 overlaps the compression bonding hole 321 formed in the compression dome 320 to form an intersection, and can form a through hole penetrating the fastening part 400 and the compression dome 320.

At this time, the fixing bolt 360 penetrates the compression bonding hole 321 and the tightening coupling hole 412 and is coupled to the fixing nut 420 on the outer surface of the tightening coupling hole 412.

That is, the fixing bolt 360 is connected to the outside of the tightening body 410 from the pressing space 340 through the pressing dome 320, and the fixing nut 420 is fixed bolt on the outer surface of the tightening coupling hole 412 ( 360), it is possible to combine the tightening portion 400 and the pressing portion (300).

Therefore, the fastening part 400 is secured by the retaining wall crimping device of the present invention by strongly binding the tension member 20 accommodated and angled by the crimping part 300, thereby fixing and maintaining the set angle to improve the safety and durability of the retaining wall. It performs the function to enable securing.

On the other hand, unlike the compression unit 300, the fastening unit 400 is a component installed in the field, and construction is performed within the installation space unit 600.

Through the above bonding process, it is possible to adjust and fix the angle between the retaining wall crimping device of the present invention and the tension member 20, which will be described in detail as a specific example.

The compression bonding hole 321 provided on the protruding curved surface of the compression dome 320 may be formed as a long hole in the longitudinal direction from the center of the compression dome 320 toward the rim.

For example, when the crimping dome 320 is necked from the top, the crimping coupling hole 321 may be configured in a shape extending from the center of the crimping dome 320 to the outer surface in four directions of east, west, south, and north.

In other words, it can be formed in a shape that is elongated left and right in the east and west directions at the top, and elongated up and down in the south and north directions.

In this case, the fastening coupling hole 412 provided in the fastening body 410 coupled along the surface of the compression dome 320 may be provided in a direction perpendicular to the compression bonding hole 321.

Of course, at this time, the fastening coupling hole 412 is provided in a number that matches the compression bonding hole 321, the tightening coupling hole 412 and the compression bonding hole 321 are crossed to come into contact with each other, fixed with the fixing bolt 360 The nut 420 forms a single intersection.

Therefore, if the tightening body 410 moves clockwise or counterclockwise along the surface of the crimping dome 320, the crimping coupling hole 321 moves to the left and right while maintaining the fixed position. As a shape, an intersection is formed.

At this time, the position of the crossing point may be a shape that changes up and down in the crimp coupling hole 321, and in the case of the tightening coupling hole 412, changes to the left and right.

On the other hand, according to an embodiment of the present invention, the fixing process due to the joining process of the fastening part 400 and the squeezing part 300, and the intersection of the squeezing hole 321 and the fastening hole 412 are various. It can be extended and applied to tangible embodiments.

That is, as shown in FIG. 4, the crimp coupling hole 321 may be configured in a shape extending from the center of the crimp dome 320 to the outer surface, or the crimp central hole 330 in the center of the crimp dome 320. It may be configured to be formed along the periphery of.

In each case, the compression bonding hole 321 may be a straight line or may be configured to be bent at a predetermined angle.

Similarly, the shape of the fastening coupling hole 412 may also be configured in a straight line or a bent shape.

In any case, the crimping coupling hole 321 and the tightening coupling hole 412 should be provided in the same number, but must be configured in a range opposite to each other.

In addition, in order to convert the mutual position and thereby create the intersection, the direction of formation of the long hole should be configured in a mutually perpendicular form.

That is, if the compression bonding hole 321 is vertical, the tightening coupling hole 412 is composed of a horizontal type and is crossed, and conversely, when the compression coupling hole 321 is horizontal, the tightening coupling hole 412 becomes a vertical type.

As a result, through the rotational movement, the crimping coupling hole 321 and the tightening coupling hole 412 can continue to form a new intersection point, and the intersection point is combined with the fixing bolt 360 and the fixing nut 420, and the crimping portion ( 300) and the fastening part 400 can be strongly bound.

Through such a smooth and simple operation, the fastening part 400 is freely attached to the crimping part 300 freely without applying any external force to the tension member 20 to be strongly fixed and maintained.

In accordance with the specific situation of the construction site and the characteristics of each type of tension member 20 according to the selective mutual combination according to the shape of the compression bonding hole 321 and the shape of the tightening coupling hole 412, the bonding and fixing of the retaining wall crimping device is firmly performed. It can be achieved.

In the end, the tension member 20 is not limited by the installation angle, and passes through the compression center hole 330 along the central tube 200 to the installation space part 600, and then tightens the compression part 400 to the compression part 300. ), The angle of the tension member 20 and the position of the fastening center hole 411 can be combined as much as possible.

Basically, the tension member 20 is manufactured and installed with the intention of being horizontally coupled to the center tube body 200, but the tension member 20 is installed to the side from the inside of the center tube body 200 without precisely matching the angle during construction. It can be accommodated while being focused.

In this case, prior to mounting the tightening part 400 to the crimping part 300, the fastening center hole 411 is fitted to the tension member 20 and then the tightening part 400 is pressed against the crimping part 300, so that the tightening occurs naturally. The pregnant woman 400 is rotated and linearly moved from the center to the crimp portion 300 and completes the angle setting with the tension member 20.

Alternatively, the fastening part 400 may be artificially moved and fixed along the surface of the crimp dome 320 in a state in which the tension member 20 is accommodated.

Then, when the fastening is fastened by using the fixing bolt 360 and the fixing nut 420 at the intersection formed in the tightening coupling hole 412 and the compression coupling hole 321, the retaining wall compression device capable of adjusting and fixing the angle of the present invention The installation of (10) is completed.

Various embodiments as described above can be selectively implemented by being modified to suit the working environment according to various variables constructed in the field.

According to another embodiment of the retaining wall crimping device 10 capable of adjusting and fixing the angle of the present invention, the tension member 20 may be composed of a plurality of anchors 501.

A plurality of anchor socket 510 is attached to the tip of each of the anchor wires 502 exposed to the installation space part 600, and functions to support the anchor wires 502 in contact with the tightening body 410, and is conical As a result, it may be formed to be wider toward the tip of the anchor wire 502 and narrower as it comes into contact with the tightening body 410.

The anchor fixing member 520 functions to support, support and fix the anchor wire 510 in a state where the anchor wire 502 is strongly biting the anchor wire 502 at the tip of the anchor wire 502.

The anchor fixing member 520 has a plate shape and is formed in a shape corresponding to the fastening body 410 and may be formed to be in close contact with the surface of the fastening body 410.

In addition, the anchor fixing member 520 may be provided with a plurality of conical through holes having a shape corresponding to the anchor socket 510 at a position facing the anchor socket 510.

Accordingly, the anchor fixing member 520 may be formed to be supported on the surface of the fastening body 410 while being engaged with the anchor socket 510 in a state in which the anchor wire 502 is fastened.

The anchor capsule 530 may be provided in the shape of a cover that protects the anchor fixing member 520, the anchor wire 502, and the anchor socket 510.

The anchor capsule 530 is formed in the shape of a concavo-convex in which a space for protecting the anchor fixing member 520 and the like is formed on the inside, and is mounted on the surface of the fastening body 410, the anchor fixing member 520, the anchor wire 502 ) And the anchor socket 510.

On the other hand, the anchor wire 502 has a need to work for re-tension to maintain a taut state after a certain period of time elapses due to the nature of the wire.

In the case of the conventional retaining wall crimping device, a component such as the crimping portion 300 is fixed to the wall without a backboard 310, and the anchor wire 502 without a fixing device between the fastening portion 400 and the crimping portion 300 It is configured in a form in which the bonding angle is maintained by the tensile force.

Therefore, in the conventional retaining wall crimping device, when a tensioning operation for re-tensioning of the anchor wire 502 is performed, the position changes as the gap between the fastening part 400 and the crimping part 300 of the coupling relationship increases, and The angle between the set fastening part 400 and the crimping part 300 is distorted, so that the angle at which the anchor wire 502 has been optimally matched with the retaining wall is changed.

This is because the direction of the force acting on the anchor wire 502 is distorted, which is a factor that greatly increases the risk of a safety accident due to the damage of the mechanically designed tension force, and also creates a great disruption in durability.

However, in the present invention, the retaining wall crimping device 10 capable of adjusting and fixing the angle can be tensioned for re-tensioning the anchor wire 502 without affecting the set angle of the anchor wire 502 at all. have.

In other words, the central tube 200 in which the anchor wire 502 is accommodated, the crimping portion 300 having the back board 310 is strongly bound to the wall of the precast panel 100 and fixed by the binding member 331 It is maintained in this state, and the fastening part 400 moves in position on the surface of the crimp part 300 according to the state in which the coupling angle of the anchor wire 502 is adjusted, and mutual fixation is achieved.

As described above, since the crimping portion 300 and the clamping portion 400 for fixing and maintaining the angle of the anchor wire 502 are provided and fastened separately from each other, the crimping portion 300 even though the anchor fixing member 520 is tensioned ) And the engaging state of the fastening part 400 is not changed at all.

Therefore, in the present invention, in the process of tensioning the anchor fixing member 520 for retensioning of the anchor wire 502 and the insertion of the anchor wedge, the existing angle set in the anchor wire 502 can be stably performed without changing at all. Can be.
