Description

Dummy structure for clamping steel strand

The present invention relates to a dummy structure used to shape a stranded wire bundle installed in a cable by tying it with a clamp in a cable bridge such as a cable-stayed bridge. It relates to a dummy structure for clamping a stranded wire that can significantly reduce costs due to replacement and maintenance by exerting a strong restraining force within the clamp even when applied.

In a cable bridge such as a cable-stayed bridge, the cable supporting the upper plate (bottom plate) of the bridge has a configuration in which strands made of a plurality of strands are arranged in a tense state in a stay pipe.

In addition, the stranded wire bundles disposed in the stay pipe are bundled and fixed through clamps to form a cross-sectional form (eg, a hexagonal cross-section) of a predetermined shape after being tensioned as a whole or individually.

In this case, the larger the diameter of the stay pipe forming the cable sheath, the larger the area to receive wind and accordingly the wind load transmitted by the cable increases. As the strength of the bridge increases, it is very unfavorable in terms of the structure of the entire bridge. Therefore, it is desirable to reduce the diameter of the stay pipe as much as possible if the same number of strands are arranged in the stay pipe.

On the other hand, when it is desired to reduce the diameter of the stay pipe in order to be less affected by the wind as described above, it is necessary to narrow the distance between the plurality of strands disposed inside the stay pipe.

In other words, it is necessary to bundle the stranded strands composed of multiple strands so that they are densely packed, but since it is possible to enter the stay pipe, the work of tying the stranded strands is essential. In this case, the stranded wire bundle is bundled together through a separate clamp to form a specific shape such as a hexagon in cross section.

However, since the number of strands installed in the cable can vary depending on the construction situation of the bridge, such as the installation location of cables, for example, when the number of strands installed is small, it is sometimes difficult to maintain the strand bundle in a specific shape. .

That is, when the number of installed strands of the strands installed in the cable is reduced, the inside of the clamp that binds the strands becomes loose, making it difficult to bundle the strands together in a specific shape.

For this reason, in the past, the strands of strands cut into short pieces remaining after use in the field were tied together with the strands through clamps and fixed to maintain the strands in a specific desired shape.

However, when the conventional method as described above is used, the rubber member attached and fixed to the inner surface of the clamp is hardened over a long time so that the strand bundle and the strand piece can be compressed and compressed, and the compression force is lowered, so that the inside of the clamp is loose. A situation of losing occurs, which causes the strands of strands caught in the clamp to be separated from the clamp by their own weight and slide downward along the inner space of the stay pipe. Accordingly, the gap between the strands tied through the clamp is widened again, making it difficult to maintain the shape, which may eventually cause a structural problem that is vulnerable to vibration.

In addition, in the case of a piece of strand that is tied and fixed together with a bundle of strands in a clamp, a bundle structure is formed in a state in which a plurality of strands are twisted together along the axial direction as in a conventional strand structure, and corrosion protection around the bundle of strands is prevented. A coating is applied for the hull, and a structure is formed in which an anticorrosive agent such as grease or wax is filled around the bundle of steel hulls in the coating. When the viscosity is lowered, the rust preventive agent filled around the steel hull of the strand manipulation flows downward by gravity and flows down to the cable anchorage located at the bottom, thereby contaminating the surrounding environment.

The present invention has been devised to solve the above problems, and the technical problem to be solved in the present invention is that vibration is continuously applied from the outside while the inside of the clamp member is loosened due to the hardening of the elastic material that wraps and compresses the stranded wire bundle. An object of the present invention is to provide a dummy structure structure for clamping a stranded wire that does not require a separate replacement operation or maintenance by allowing a strong binding force to be exerted within the clamp member.

Another technical problem to be solved in the present invention is to provide a dummy structure structure for clamping a strand that can prevent the contamination around the cable anchorage due to leakage of a rust preventive agent due to an external temperature change.

Another technical problem to be solved in the present invention relates to a dummy structure for clamping a strand that can reduce manufacturing cost and can be easily installed immediately on site to improve workability.

A dummy structure for clamping a strand according to the present invention for solving the above technical problem is located in a clamp member that wraps around a bundle of strands and binds them together, and the body is between the clamp member and the strand, or between the strand and strand It is characterized in that it is pressed and fixed together with the strand by the fastening force of the clamp member while filling the space of the.

Here, the body may be formed in a hollow tubular structure or a filled rod-shaped structure made of a synthetic resin or metal material.

And, the body may be provided with a locking means for suppressing the downward movement of the body caught on the clamp member or adjacent strands.

In this case, as the locking means, a bolt having a hook portion coupled to the upper surface of the body and supported by a hook portion hooked on the other side of the clamp member may be employed.

In addition, as the locking means, an eye bolt having a ring portion formed on one side and fastened to the upper surface of the body, and a binding member fixed by binding or hooking to a strand or clamp member portion in a state of being fitted to the ring portion of the eye bolt can be employed.

In addition, as the locking means, a through hole formed through the outer surface of the body and a binding member fixed to a strand or a clamp member portion while being fitted in the through hole may be employed.

In addition, as the locking means, an annular groove formed along the outer circumferential surface of the body, and a binding member fixed to a strand or a clamp member in a state fitted in the annular groove may be employed.

In addition, as the locking means, an annular groove formed along the outer circumferential surface of the body, and a ring member having a ring shape that is fitted into the annular groove to form a diameter larger than the diameter of the body may be employed. have.

In addition, as the locking means, an annular protrusion structure formed while forming a protruding structure around the outer circumferential surface of the body to form a diameter larger than the diameter of the body may be employed.

In addition, as the locking means, a tapered structure formed on the outer surface of the body in a shape in which the diameter is gradually reduced from the top to the bottom may be employed.

According to the structure of the dummy structure for clamping the strand of the present invention as described above, the clamp member or strand bundle portion adjacent to the body portion of the dummy structure is provided with a locking means capable of suppressing downward movement, so that it is attached to the inner surface of the clamp member. Even when vibration is continuously applied to the cable by applying an external force (for example, wind) in a state where the elastic material is hardened and the inside is loose, the dummy structure can exert a strong restraining force inside the clamp member, so the strand shape is disturbed. This phenomenon can be prevented, and since it is possible to prevent the dummy structure from being separated from the clamp member and falling downward, there is an advantage in that it is possible to reduce costs due to maintenance and replacement of the dummy structure.

In addition, since the dummy structure is formed in a light-weight synthetic resin or metal rod-like structure, it is easy to manufacture and has the advantage of low manufacturing cost, and the weight is relatively light compared to the existing strand-type dummy structure. Since it is less affected by gravity, it has the advantage that it is not easily separated from the clamp member even when a vibration load due to wind force is continuously applied to the cable. Since contamination does not occur, there is an advantage in that the cost of maintenance of the cable fixing part can be reduced.

In addition, since the dummy structure has a simple shape and structure, it is easy to manufacture and can reduce manufacturing costs, and since it can be easily installed immediately through a simple operation at the cable installation site, workability can be improved.

Hereinafter, preferred embodiments of a dummy structure for clamping a strand according to the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

And the terms to be described later are terms set in consideration of the function in the present invention, which may vary according to the intention or custom of the producer producing the product, so the definition may be made based on the content throughout this specification.

First, FIG. 1 is a cross-sectional view showing the configuration of the cable periphery in which the dummy structure for clamping the strand of the present invention is installed, and FIG. 2 is a perspective view showing the installation of a clamp member for tying a bundle of strands around the cable anchorage of the pylon part of the bridge am.

1 and 2 , in a cable bridge such as a cable-stayed bridge, a plurality of cables 30 for supporting the load of the upper plate 20 are installed between the pylon 10 and the upper plate 20 . The cable 30 is a stay pipe 34 made of a steel or synthetic resin material in which a stranded wire bundle 32 made of a plurality of stranded wires 31 is disposed so that one end is fixed to the upper plate 20 portion and the other One end is fixed to the pylon 10 through a tensile operation.

And, in the vicinity of the cable anchorage 60 located in the upper plate 20 and the cable anchorage 50 located in the pylon 10 part, the stranded wire bundle in the cable 30 fixed through each of the cable anchorages 50 and 60 ( 32) are gathered together and a clamp member 40 is installed to tie them together so as to maintain them in a predetermined shape.

The clamp member 40 is formed to have a cylindrical or polygonal shape of a predetermined length so as to wrap the outer periphery of the stranded wire bundle 32, and serves to bind the stranded wire bundle 32 together so that it has a predetermined shape.

That is, the clamp member 40 is formed in a form in which both sides of the two divided members are symmetrical, one side is hinged to each other and the other side is coupled with a fastener. It can be fixed by bundling the stranded wire bundle (32).

At this time, on the inner surface of the clamp member 40, an elastic member 42 made of an elastic material such as rubber is elastically closely adhered to the outer periphery of the stranded wire bundle 32 during the fastening process of the clamp member 40 to exert a firm fixing force. Attachment is fixed.

In addition, a damper 70 for attenuating vibration of the cable 30 when an external force such as wind power is applied to the cable 30 may be installed on one side of the cable 30 .

On the other hand, FIG. 3 shows the cross-sectional structure of part A-A of FIG. 2 , and shows an internal structure in which the stranded wire bundle 32 is bundled through the clamp member 40 .

As shown in FIG. 3 , the stranded wire bundle 32 disposed inside the stay pipe 34 forming the sheath of the cable 30 is bundled together with a plurality of dummy structures 100 through the clamp member 40 . is fixed

As shown in FIG. 3 , the conventional stranded wire 31 structure forms a bundle structure in which a plurality of steel wire bodies 31a are twisted with each other along the axial direction, and the steel wire body 31a prevents corrosion around the bundle. A coating 31b for have.

And, as described above, in the dummy structure 100, when the number of strands bitten in the clamp member 40 is small, it is difficult to bundle the strands 32 and keep them in a constant shape. It is a structure used to bind one or more dummy structures having a shape together with the stranded wire bundle 32 together with the clamp member 40 to maintain the external shape in a specific shape (a hexagonal shape in the embodiment).

Conventionally, a method of binding and fixing strands of strands used in the cable construction process together with a bundle of strands 32 with a clamp member 40 was mainly used, but these strands of strands are not uniform in length, so it is effective to securely tie them with a clamp member. As the elastic material attached to the inner surface of the clamp member hardens after a long time and vibration is continuously applied while the fixing force is lowered, a piece of heavy stranded wire is separated from the clamp member by its own weight and moves downward along the inside of the stay pipe. There was a problem of loss, and in addition, the viscosity of the rust preventive agent filled in the strands of the stranded wire in the summer when the temperature was high was lowered and flowed down, thereby contaminating the environment around the cable anchorage.

In order to improve such conventional problems, in the present invention, one or more dummy structures 100 having a diameter corresponding to the diameter of the strand 31 and having a hollow rod-shaped structure or a hollow tubular structure 100) is tied together with the stranded wire bundle 32 with the clamp member 40 so that the overall shape of the stranded wire bundle 32 can be maintained in a constant shape even when the number of strands of the stranded wire 31 is insufficient. The case of the dummy structure of the structure will be described as an example)

The dummy structure 100 has a body 110 formed of a light weight made of a light metal material such as a synthetic resin material or aluminum, which is the same as the covering material of the stranded wire 31, and is a part of the outer part of the stranded wire bundle 32 or the stranded wire bundle 32 ) is disposed in the space between the strands and is tied and fixed together with the strand bundle 32 through the clamp member 40 .

That is, in the clamp member 40 , the dummy structure 100 fills the space between the clamp member 40 and the strand 31 or the space between the strand 31 and the strand 31 , and the clamp member 40 . It is pressed together with the stranded wire bundle 32 by the fastening force of the and fixed.

In this case, the clamp member 40 for tying the stranded wire bundle 32 is located close to the cable anchorage port 50 of the pylon 10 part and the cable anchorage port 60 of the upper plate 20 part as shown in FIG. 1 . Since they are installed on each side, the dummy structure 100 structure as described above is applied to each clamp member 40 installed in each of these parts, so that the stranded wire bundle 32 can be gathered and fixed to have a specific cross-sectional shape.

4 is a list of various embodiments applicable to the actual field in the dummy structure 100 according to the present invention.

First, the dummy structure 100 of the form shown in (a) of FIG. 4 is formed to have a tapered shape in which the shape of the body 110 is gradually reduced in diameter from the top to the bottom.

That is, in the dummy structure 100 shown in (a) of FIG. 4 , a tapered portion 112 having a shape that is gradually reduced in diameter from the top to the bottom is formed on the outer surface of the body 110, as shown in FIG. As shown in the installation cross-sectional view shown in a), in the case where it is tied and fixed together with the clamp member 40 together with the stranded wire bundle 32, on the upper side of the clamp member 40, between the clamp member 40 and the stranded wire 31 It may be installed in such a way that the body 110 of the dummy structure 100 is press-fitted out of the gap space.

In this case, in the dummy structure 100 press-fitted into the clamp member 40 , the upper end of the body 110 having a large diameter is not press-fitted between the clamp member 40 and the strand 31 , and the clamp member 40 is The downward movement is suppressed by being caught between the upper end and the stranded wire 31 .

Therefore, the elastic member 42 such as rubber attached to the inner surface of the clamp member 40 to improve the fixing force is hardened after a long time, and even if vibration is continuously applied from the outside in a state in which the fixing force is lowered, the tapered body 110 ) The upper end of the clamp member 40 is caught between the upper end of the clamp member 40 and the strand 31 to suppress the downward movement of the dummy structure 100 , thereby preventing the dummy structure 100 from being separated from the clamp member 40 and falling downward. can do.

In addition, the shape of the dummy structure 100 shown in FIG. 4(b) is a modified example of the dummy structure 100 shown in FIG. The structure formed only in the upper part is shown.

That is, the body 110 portion of the dummy structure 100 that is closely fixed between the clamp member 40 and the stranded wire 31 is formed in a circular rod shape having the same diameter, and the clamp member 40 and the stranded wire 31 . The upper side of the body 110, which is not engaged therebetween, has a structure in which a tapered portion 112 having a diameter gradually expanding toward the upper portion is formed.

Accordingly, in a state in which the dummy structure 100 is installed as shown in FIG. 5B , even when vibration is continuously applied to the cable under the influence of wind, the gap between the clamp member 40 and the stranded wire 31 . Due to the shape of the tapered portion 112 on the upper portion of the body 110 having a larger area, the dummy structure 100 may be prevented from being moved downward and separated from the clamp member 40 .

And, in FIG. 4(c) , the structure of the dummy structure 100 in which a separate tapered structure is not formed on the outer surface of the body 110 is shown. In the dummy structure 100 according to the present invention, since the material of the body 110 is basically composed of a light plastic material such as a covering of the stranded wire 31 or a light light metal material such as aluminum, a separate engaging means on the outer surface of the body 110 Even if this is not provided, the downward movement of the dummy structure 100 can be suppressed to a certain level because the downward force by its own weight is smaller than the restraining force within the clamp member 40 .

That is, since the dummy structure 100 itself is made of a light-weight material, it is relatively less affected by gravity compared to the case of using a conventional strand piece having a large weight. When the binding force of 100 is maintained to some extent, the dummy structure 100 is not easily separated from the clamp member 40 even when vibration is applied.

Meanwhile, FIG. 6 shows another embodiment of the dummy structure 100 according to the present invention.

First, the dummy structure 100 of the form shown in (a) of FIG. 6 has a separate structure-type engaging means that can be caught on the upper end of the clamp member 40 on the upper end of the body 110 having a filled circular rod shape. It is a prepared form.

That is, the dummy structure 100 shown in (a) of FIG. 6 is a hook part 113 having a 'L'-shaped bent structure coupled to the upper surface of the body 110, and the hook part 113 ), a male screw part 113a is formed on one side and is coupled to the female screw part 111 formed on the upper surface of the body 110, and the other side 113b is extended outward of the body 110 to the upper end of the clamp member 40. It is configured to take

At this time, the hook part 113 can be managed as a separate part from the body 110 , and after fastening the hook part 113 with the body 110 at the construction site, it is tied together with the stranded wire bundle 32 and clamped. It can be fixed with the member 40 .

Therefore, as shown in the installation cross-sectional view shown in (a) of FIG. 7 , the dummy structure 100 is tied and fixed with the clamp member 40 together with the stranded wire bundle 32 in the outward direction of the body 110 . As one side 113b of the hook portion 113 extended to be supported by being caught on the upper end of the clamp member 40, even if vibration is continuously applied from the outside while the inside of the clamp member 40 is loosened, the dummy structure 100 is A stable binding force may be secured within the clamp member 40 .

In this case, the hook part 113 may be formed in various shapes as long as it has a structure that can be effectively caught on the upper end of the clamp member 40 in addition to the 'L' shape as described above.

And, the dummy structure 100 shown in (b) of FIG. 6 shows a form in which an eye bolt 114 is coupled to the upper surface of the body 110 as a locking means.

The eye bolt 114 has a structure in which a ring portion 114b is formed at the upper end and a male screw portion 114a is formed at the lower end. concatenated and joined.

At this time, a binding member 114d, such as a string or wire, is attached to the ring portion 114b of the eye bolt 114 to bind and fix the dummy structure 100 to the adjacent strand 31 or clamp member 40 portion. will be plugged in

Therefore, as shown in the installation cross-sectional view shown in (b) of FIG. 7, the ring part of the eye bolt 114 ( The binding member 114d, such as a string or wire, is inserted into the 114b) and wound around the adjacent strand 31 or stranded strand 32, or it can be tied to the clamp member 40 and fixed.

When the dummy structure 100 is fixed in this form, even if vibration is continuously applied from the outside in a state in which the inside of the clamp member 40 is loosened, the ring portion 114b of the eye bolt 114 and the stranded wire bundle 32 Alternatively, since the downward movement of the dummy structure 100 can be suppressed through the binding member 114d that binds between the clamp members 40, the stranded wire bundle 32 retains its original shape within the clamp member 40. By keeping it as it is, it is possible to maintain the binding state.

In addition, (c) of FIG. 6 shows the structure of the dummy structure 100 in which a through hole 115 through which a binding member 115a such as a string or wire can pass through is formed on the outer surface of the body 110 of the dummy structure 100. is showing

The dummy structure 100 having such a shape structure is a dummy structure 100 in which the dummy structure 100 is tied and fixed with a clamp member 40 together with the strand bundle 32 as shown in the installation cross-sectional view shown in FIG. By penetrating the binding member 115a through the through-hole 115 formed in the body of the dummy structure 100 in the state and fixing it to the adjacent stranded wire bundle 32 or clamp member 40 portion, the vibration applied from the outside Even if a force is applied to the dummy structure 100 to descend downward by the dummy structure 100, the dummy structure 100) is not separated from the clamp member 40, it is possible to secure a stable binding force.

In this case, one or more through-holes 115 formed in the body portion of the dummy structure 100 may be formed in the outer circumferential surface of the body 110 for convenience of installation work. In this case, when the through-holes 115 on one side formed in the body 110 of the dummy structure come into contact with the inner circumferential surface of the adjacent stranded wire 31 or the clamp member 40 to be covered, the through-holes 115 formed at a different position. By inserting the binding member 115a through the dummy structure 100 can be easily performed.

Meanwhile, FIGS. 8(a) to 8(c) list and show another embodiment of the dummy structure 100 of the present invention.

The dummy structure 100 of the form shown in FIGS. 8 (a) to (c) is an adjacent strand by hanging a binding member 116a such as a string or wire around the outer surface of the upper side of the body 110 in the form of a circular rod. (31) or an annular groove 116 is formed so as to be bound to the clamp member 40 portion.

At this time, the annular groove 116 is formed to have a circular cross-sectional shape as shown in FIG. can be

And, as shown in the installation cross-sectional view shown in FIG. 9 , the dummy structure 100 in which the annular groove 116 is formed is fixed by binding the dummy structure 100 together with the strand bundle 32 with a clamp member 40 . In this state, the downward movement of the dummy structure 100 can be suppressed by hooking the binding member 116a to the annular groove 116 and binding it to the adjacent strand bundle 32 or the clamp member 40 portion.

Alternatively, a cable tie used to bundle various cables in the annular groove 116 in a state in which the dummy structure 100 is bundled and fixed together with the stranded wire bundle 32 by a clamp member 40 (cable tie; not shown) ), the cable tie portion protruding out of the outer surface of the dummy structure 100 may be caught on the adjacent strand 31 or the clamp member 40 to suppress downward movement of the dummy structure 100 .

In addition, as described above, the dummy structure 100 is fixed by hooking the binding member 116a to the annular groove 116 portion of the dummy structure 100 to tie it to the adjacent strand bundle 32 or the clamp member 40 portion. Although it is possible to suppress the downward movement of, in addition to this, by coupling an elastically deformable ring member such as a rubber ring to the annular groove 116 portion, the portion to which the ring member (not shown) is coupled is a dummy structure By forming to have a larger diameter than the diameter of the body of 100, the ring member portion coupled to the annular groove 116 is between the strand 31 and the strand 31, or between the strand 31 and the clamp member ( 40) to forcibly suppress the downward movement of the dummy structure 100 .

Meanwhile, FIGS. 10 (a) and (b) show another embodiment of the dummy structure 100 according to the present invention, in which the annular protrusion 117 is integrally formed around the upper outer peripheral surface of the body 110. The formed structure is shown.

In this case, the annular protrusion 117 is integrally formed with the body 110 to have an expanded diameter greater than the body diameter of the dummy structure 100 .

In this case, the longitudinal cross-sectional shape of the annular protrusion 117 may have an outer surface formed in a circular shape as shown in FIG. It is not limited to the shape.

In this way, as the annular protrusion 117 having an expanded diameter is formed on the outer peripheral surface of the upper side of the body of the dummy structure 100, as seen in the installation cross-sectional view shown in FIG. 11 ,

An annular protrusion 117 formed on the upper side of the dummy structure 100 in a state in which the dummy structure 100 is tied and fixed together with the stranded wire bundle 32 by the clamp member 40 is adjacent to the upper end of the clamp member 40 and The downward movement of the dummy structure 100 is suppressed by being caught between the covered outer peripheral surfaces of the stranded wire 31 .

Therefore, even when the force to move downward is applied to the dummy structure 100 as a vibration is continuously applied from the outside while the elastic member in the clamp member 40 is hardened after a long time and the fixing force is loosened, the dummy structure 100 ), the annular protrusion 117 on the upper side is caught between the upper end of the clamp member 40 and the outer circumferential surface of the strand 31, so that downward movement of the dummy structure 100 can be forcibly suppressed, The dummy structure 100 can secure a stable binding force within the clamp member 40 , and thus, there is no replacement and maintenance cost due to separation and loss of the dummy structure 100 , thereby realizing cost savings.

In the above, preferred embodiments of the present invention have been described, but the scope of the present invention is not limited to such specific embodiments, and those of ordinary skill in the art may appropriately change within the scope described in the claims of the present invention.
