Description

Technical Field

[0001] The utility model relates to a cable saddle structure of a suspension bridge, in particular to a saddle groove protection structure which serves during a construction period after the main cable is erected or during a period from the construction period to the operation period. Background Art

[0002] In the structure of a suspension bridge, the main cable is the core load-bearing component that carries dynamic and static loads. In the construction of a suspension bridge, the main cable needs to be supported by a cable saddle structure including the main cable saddle and loose cable saddle, and then the cable clamp connection and bridge deck construction are carried out. The construction period is usually several years.

[0003] In the structure of a suspension bridge, in order to protect the saddle and the connection structure between the saddle and the main cable from erosion by corrosive substances (such as dust, rain, etc.) in the surrounding working environment, it is necessary to connect a saddle cover to the saddle to isolate the saddle and the connected structure from the surrounding working environment. For example, Chinese patent documents disclose technologies named "saddle cover for main saddle of suspension bridge", publication number CN205062661 U, publication date March 2, 2016, and "a cable-stayed bridge cable saddle", publication number CN203866706 U, publication date October 8, 2014. However, the protection of the saddle by the saddle cover is during the operation and service process after the suspension bridge is built, and does not include the construction period during construction.

[0004] Since the construction period of a suspension bridge is several years, the construction period from the completion of the erection of the main cable in the saddle to the completion of the construction of the entire bridge is usually more than one year. Moreover, during the construction of a suspension bridge, the surrounding working environment is worse than during the service period. In addition to erosion caused by dust, rain, etc., there are also erosion caused by various iron filings during construction, as well as trampling and bumping during construction. In addition, the saddle groove structure of the saddle is relatively narrow, and there are many blind spots for cleaning. This is especially prominent in the structure where the pull rod connected to the saddle body locks the main cable installed by filling zinc blocks, which increases the difficulty of cleaning visible solid or semi-solid erosion in the saddle groove. Therefore, during the construction period of a suspension bridge, it is even more necessary to shield and protect the saddle groove of the saddle to prevent erosion from entering the saddle groove and causing adverse effects on the connection structure between the saddle and the main cable.

[0005] As mentioned above, the currently mature saddle covers are used after the construction of suspension bridges is completed, and cannot be used to protect the saddles and saddle grooves during the construction period without hindering the construction work.

[0006] In the prior art known to the applicant, no effective technical means have been disclosed for protecting the saddles and grooves during the construction of suspension bridges. At the construction site, the saddles and grooves are usually protected by simply overlapping thin plates (such as iron sheets) or cloth (such as tarpaulins) and are randomly covered without forming a standardized arrangement and stably connected covering protection structure. Not only is the shielding and protection effect of the saddles and grooves poor, but there are also great safety hazards to construction workers stepping on them and passing nearby.

[0007] Therefore, in view of the particularity of the construction period of the above-mentioned suspension bridge and the shortcomings of the existing technology, it is necessary to design a protective structure that can be used during the construction period of the suspension bridge to stably shield and protect the saddle and saddle groove, so as to reduce the erosion of the inside of the saddle and saddle groove by corrosive materials during the construction period and ensure construction safety. Utility Model Content

[0008] The technical purpose of the utility model is to provide a protective structure that does not hinder the construction work and can stably shield and protect the saddle and saddle groove during the construction period, namely, a saddle and saddle groove protective structure, in view of the particularity of the construction period of the above-mentioned suspension bridge and the shortcomings of the existing technology.

[0009] The technical purpose of the utility model is achieved by the following technical solution: a cable saddle saddle groove protection structure, comprising a saddle body, wherein the saddle body has a saddle groove for passing a main cable;

[0010] During the construction of the suspension bridge, the main cable is installed in the saddle groove along the longitudinal direction of the saddle body and is locked by a plurality of tie rods installed in the transverse direction of the upper part of the saddle groove;

[0011] After the main cable is installed in the saddle groove of the saddle body, a cover plate capable of shielding the saddle groove in a top view of the saddle body is connected to the top of the saddle body in a detachable structure;

[0012] The covering plate shields and protects the saddle groove and the main cable installed therein in a top view of the saddle body, and the main cable installed in the saddle groove is located below the covering plate.

[0013] The saddle body is a main cable saddle or a loose cable saddle of a suspension bridge.

[0014] The above-mentioned technical measures are aimed at the particularities of the construction period of the above-mentioned suspension bridge. A covering plate that can stably cover the saddle groove is connected to the saddle during the construction period. The molded structure of the covering plate on the saddle does not hinder the normal progress of construction work, and can stably shield and protect the saddle groove of the saddle during the construction period, so as to reduce the erosion of the inside of the saddle groove by corrosive materials during the construction period and ensure construction safety.

[0015] As one of the preferred technical solutions, the side edges of the cover plate in the horizontal width direction are correspondingly located at the outer edges of the notches on both sides of the saddle groove;

[0016] Furthermore, the cover plate is formed in an arc-shaped structure along the contour trajectory of the upper notch of the saddle groove in the longitudinal direction.

[0017] Furthermore, the edge of the covering plate in the transverse width direction is connected to the outer edge of the corresponding notch of the saddle groove in a detachable structure through a plurality of connecting screws.

[0018] Furthermore, a rubber pad is provided at the outer edge of the notch of the saddle groove;

[0019] The side portion of the cover plate in the transverse width direction is seated on the outer edge of the corresponding notch of the saddle groove through the rubber pad.

[0020] The cover plate of the above technical measures has good matching with the outer edge of the saddle groove notch at the top of the saddle, and can form a stable and detachable connection between the cover plate and the top of the saddle without hindering normal construction. The connection structure of the cover plate at the top of the saddle is standardized and stable, with good shielding and protection effects, and is safe and stable. In addition, the rubber pad, on the one hand, plays a protective role of flexible separation for the connection structure between the cover plate and the saddle, so as to avoid unnecessary damage to the saddle due to direct contact between the cover plate and the saddle; on the other hand, it effectively improves the sealing effect of the connection between the cover plate and the saddle body, further reducing the intrusion of rainwater, dust, etc. into the saddle groove; on the third hand, after the construction period ends and the operation period begins, a breathable channel is reliably formed inside the saddle groove to reduce the volume increase and diffusion of the dry gas of the main cable inside the saddle cover, which is especially significant when the end cover shell and the cable sleeve are directly matched.

[0021] As one of the preferred technical solutions, the cover plate is a patterned steel plate structure.

[0022] Further, the cover plate is a single-side pattern structure, having a smooth side and a pattern side;

[0023] In the connection structure between the cover plate and the saddle body, the smooth side is used as a bonding surface for bonding with the top of the saddle body, and the patterned side is used as a bearing surface that can be stepped on during the construction process.

[0024] Furthermore, the minimum thickness of the cover plate is 6 mm.

[0025] The covering plate of the above technical measures can form a pedal force-bearing platform of the friction-enhancing structure while meeting the shielding and protection effect of the saddle groove, which is beneficial for construction workers to walk in an anti-slip manner and ensure safety during walking.

[0026] As one of the preferred technical solutions, the end of the cover plate in the longitudinal direction of the saddle body extends out of the end surface of the slot corresponding to the saddle groove. This technical measure is conducive to increasing the coverage of the cover plate on the saddle groove, improving the shielding and protection effect, and also conducive to increasing the support surface for construction and trampling.

[0027] Furthermore, at least one end of the saddle body in the longitudinal direction is connected with an end cover shell forming a U-shaped profile structure, which cooperates with the saddle groove in the longitudinal direction and cooperates with the cover plate in the up-down direction;

[0028] A main cable installation channel is formed between the end cover shell and the corresponding extended section of the cover plate.

[0029] Furthermore, the inner end of the end cover is connected to the corresponding notch end surface of the saddle body in a detachable structure through a plurality of connecting screws;

[0030] A rubber pad is arranged between the inner end of the end cover shell and the corresponding notch end surface.

[0031] Furthermore, the outer edges of the notches on both sides of the top of the end cover are connected to the corresponding extended sections of the cover plate in a detachable structure through a plurality of connecting bolts;

[0032] A rubber pad is arranged between the outer edge of the notch of the end cover shell and the corresponding extension section of the cover plate.

[0033] The above technical measures are based on the outer edge structure of the cover plate in the longitudinal direction of the saddle body, and the end cover of the U-shaped structure is connected at the corresponding end of the saddle body to extend the saddle groove in the longitudinal direction, so that the end cover plays a role of blocking transition in the protection of the saddle groove in the longitudinal direction, so as to improve the protection effect of the saddle groove. In addition, the longitudinal extension of the saddle groove by the end cover can also be used to directly connect the end of the cable sleeve at the saddle, so there is no need to connect the end of the cable sleeve at the saddle with the saddle cover in the traditional way, and the end cover is directly connected to the cable sleeve. The structure effectively reduces the volume increase and diffusion of the dry gas of the main cable inside the saddle cover, which is conducive to improving the technical effect and economy of the blast drying of the main cable.

[0034] As one of the preferred technical solutions, the edge of the cover plate in the horizontal width direction is flush with the outer edge of the outer edge of the corresponding side notch of the saddle groove. This technical measure can not only meet the shielding and protection effect of the saddle groove, but also reduce the position interference of the cover plate on the surrounding environment. After the construction of the suspension bridge is completed, it will not hinder the connection of the saddle cover, that is, before the saddle cover is connected, the cover plate can be removed or not.

[0035] The beneficial technical effect of the utility model is as follows: the above technical measures are aimed at the particularity of the construction period of the above suspension bridge, and a covering plate that can stably block the saddle groove is connected to the cable saddle during the construction period. The molding structure of the covering plate on the cable saddle does not hinder the normal development of the construction work, and can stably block and protect the cable saddle groove during the construction period, so as to reduce the erosion of the inside of the cable saddle groove by corrosive materials during the construction period, and ensure the safety of construction. In addition, the molding structure of the covering plate can form an anti-skid trampling force platform, which is conducive to the anti-skid trampling passage of construction personnel to ensure the safety of trampling passage.

[0044] The utility model relates to a cable saddle structure of a suspension bridge, specifically a saddle groove protection structure that is used during the construction period after the main cable is erected or during the construction period and the subsequent operation period. The main technical solution of the utility model is specifically described below in combination with multiple embodiments. Figure 1 , Figure 2 and Figure 3 The technical solution of the utility model is clearly and in detail explained; Example 2 is combined with the accompanying drawings of the specification - that is, Figure 4 , Figure 5 , Figure 6 and Figure 7 The technical solution of the utility model is clearly and in detail explained; although other embodiments are not separately drawn with drawings, their main structures can still refer to the drawings of embodiment 1 or embodiment 2.

[0045] It should be noted that the drawings of the present invention are schematic, and unnecessary details have been simplified to clarify the technical purpose of the present invention, so as to avoid blurring the technical solution of the present invention in the prior art. In addition, the expressions "approximately" and "substantially" in the following text regarding quantity or matching relationship mean that reasonable assembly errors and processing errors in the industry are allowed to exist, and do not literally express absolute quantity or matching relationship.

[0046] Example 1

[0047] See also Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a saddle groove protection structure used in the construction period of a suspension bridge, which includes a saddle body 1 and a covering plate 2.

[0048] Specifically, the saddle body 1 is a main cable saddle in a suspension bridge structure, and has a saddle groove 11 on its upper portion for passing a main cable.

[0049] During the construction of the suspension bridge, the main cable is installed in the saddle groove 11 along the longitudinal direction of the saddle body 1, and multiple tie rods installed in the tie rod holes 12 corresponding to each other in the transverse direction of the upper part of the saddle groove 11 are locked by multiple zinc blocks arranged in the saddle groove 11. Before the saddle cover is connected, the saddle groove 11 on the saddle body 1 and the main cable installed in the saddle groove 11 (including the structure for locking the main cable) are shielded and protected by the cover plate 2 to reduce the intrusion of corrosive substances into the saddle groove 11.

[0050] The cover plate 2 is a steel plate with a single-side pattern structure, that is, one side of the cover plate 2 is a smooth structure and the other side is a pattern structure. To ensure structural strength, the minimum thickness of the cover plate 2 (i.e. the thickness of the main part, excluding the height of the pattern protrusion) is about 6mm.

[0051] The dimension of the cover plate 2 in the transverse direction substantially matches the dimension between the outer edges of the notches on both sides of the saddle groove 11 in the transverse direction of the saddle body 1. The dimension of the cover plate 2 in the longitudinal direction is slightly larger than the dimension between the end faces of the notches on both ends of the saddle groove 11 in the longitudinal direction of the saddle body 1.

[0052] The cover plate 2 of the above structure has two side edges corresponding to the outer edges of the notches on both sides of the saddle groove 11 in the horizontal width direction, and the outer edges of the edges of the cover plate 2 are within the coverage range of the outer edges of the notches on the sides (at most, they are flush with the outer edges of the outer edges of the notches on the sides). Therefore, the cover plate 2 is an arc-shaped structure along the contour trajectory of the upper notch of the saddle groove 11 in the longitudinal direction. Of course, in order to ensure the stability of the combination of the cover plate 2 and the outer edges of the notches of the saddle groove 11, the cover plate 2 in the connection structure with the saddle body 1 should use the smooth side as the combination surface for combining with the top of the saddle body 1, and use the patterned side as the anti-slip bearing surface facing upwards and treadable during the construction process, which is opposite to the saddle body 1. After the cover plate 2 of the above structure is in place at the outer edges of the notches on both sides of the saddle groove 11 through the two side edges, the two ends in the longitudinal direction should extend out of the end faces of the notches on both ends of the saddle groove 11 to further increase the shielding and protection effect.

[0053] After the covering plate 2 of the above structure is seated in place at the outer edges of the grooves on both sides of the saddle groove 11 through the side edges, it is connected to the corresponding outer edges of the grooves of the saddle groove 11 in a detachable structure at the side edges in the horizontal width direction through multiple connecting screws 3.

[0054] In the connection structure between the cover plate 2 and the saddle body 1, in order to prevent the cover plate 2 from scratching the outer edges of the notches on both sides of the saddle groove 11 and improve the sealing effect of the joint, a rubber pad 4 with a thickness of about 3 mm is provided at the outer edges of the notches of the saddle groove 11, and the edges of the cover plate 2 in the horizontal width direction are seated on the outer edges of the corresponding notches of the saddle groove 11 through the corresponding rubber pads 4. Of course, the connection screws 3 connecting the cover plate 2 and the saddle body 1 should pass through the rubber pads 4.

[0055] Through the above structure, a covering plate 2 capable of shielding the saddle groove 11 (including the main cable threading structure in the saddle groove) in the top view direction of the saddle body 1 is connected to the top of the saddle body 1 in a detachable structure. The saddle groove 11 and the main cable threaded therein are shielded and protected by the covering plate 2 in the top view direction of the saddle body 1, and the main cable threaded therein is located below the covering plate 2.

[0056] Example 2

[0057] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the utility model is a saddle groove protection structure used in the construction period of a suspension bridge, which includes a saddle body 1, a covering plate 2 and two groups of end covers 5.

[0058] Specifically, the saddle body 1 is a main cable saddle in a suspension bridge structure, and has a saddle groove 11 on its upper portion for passing a main cable.

[0059] During the construction of the suspension bridge, the main cable is installed in the saddle groove 11 along the longitudinal direction of the saddle body 1, and multiple tie rods installed in the tie rod holes 12 corresponding to each other in the transverse direction of the upper part of the saddle groove 11 are locked by multiple zinc blocks arranged in the saddle groove 11. Before the saddle cover is connected, the saddle groove 11 on the saddle body 1 and the main cable installed in the saddle groove 11 (including the structure for locking the main cable) are shielded and protected by the cover plate 2 to reduce the intrusion of corrosive substances into the saddle groove 11.

[0060] The cover plate 2 is a steel plate with a pattern structure. To ensure structural strength, the minimum thickness of the cover plate 2 (i.e. the thickness of the main part, excluding the height of the pattern protrusion) is about 6 mm.

[0061] The dimension of the cover plate 2 in the transverse direction substantially matches the dimension between the outer edges of the notches on both sides of the saddle groove 11 in the transverse direction of the saddle body 1. The dimension of the cover plate 2 in the longitudinal direction is greater than the dimension between the end faces of the notches on both ends of the saddle groove 11 in the longitudinal direction of the saddle body 1.

[0062] The cover plate 2 of the above structure has two side edges corresponding to the outer edges of the notches on both sides of the saddle groove 11 in the horizontal width direction, and the outer edges of the side edges of the cover plate 2 are within the coverage range of the outer edges of the notches on the sides (at most, they are flush with the outer edges of the outer edges of the notches on the sides). Therefore, the cover plate 2 is an arc-shaped structure along the contour trajectory of the upper notch of the saddle groove 11 in the longitudinal direction. After the cover plate 2 of the above structure is seated in place at the outer edges of the notches on both sides of the saddle groove 11 through the two side edges, the two ends in the longitudinal direction should extend out of the end faces of the notches on both ends of the saddle groove 11 to further increase the shielding and protection effect.

[0063] After the covering plate 2 of the above structure is seated in place at the outer edges of the grooves on both sides of the saddle groove 11 through the side edges, it is connected to the corresponding outer edges of the grooves of the saddle groove 11 in a detachable structure at the side edges in the horizontal width direction through multiple connecting screws 3.

[0064] In the connection structure between the cover plate 2 and the saddle body 1, in order to prevent the cover plate 2 from scratching the outer edges of the notches on both sides of the saddle groove 11 and improve the sealing effect of the joint, a rubber pad 4 with a thickness of about 3 mm is provided at the outer edges of the notches of the saddle groove 11, and the edges of the cover plate 2 in the horizontal width direction are seated on the outer edges of the corresponding notches of the saddle groove 11 through the corresponding rubber pads 4. Of course, the connection screws 3 connecting the cover plate 2 and the saddle body 1 should pass through the rubber pads 4.

[0065] Through the above structure, a covering plate 2 capable of shielding the saddle groove 11 (including the main cable threading structure in the saddle groove) in the top view direction of the saddle body 1 is connected to the top of the saddle body 1 in a detachable structure. The saddle groove 11 and the main cable threaded therein are shielded and protected by the covering plate 2 in the top view direction of the saddle body 1, and the main cable threaded therein is located below the covering plate 2.

[0066] The two groups of end covers 5 have the same structure. They are disposed at both ends of the saddle body 1 in the longitudinal direction, that is, they are disposed corresponding to the end extension sections of the above-mentioned cover plate 2 at both ends of the saddle body 1 in the longitudinal direction.

[0067] The end cover 5 is a U-shaped cross-section structure formed by welding or rolling steel plates. The contour structure of its U-shaped groove basically matches the contour of the saddle groove 11 on the saddle body 1. Its inner end, as the docking part with the corresponding notch end face of the saddle body 1, has a flange edge formed by folding outwards, and multiple screw holes are arranged at intervals on the flange edge of the U-shaped track. The outer edges of the notches on both sides of its top serve as docking parts with the corresponding extension sections extending from the saddle body 1 of the cover plate 2, respectively, and have flange edges formed by folding outwards, and multiple bolt holes are arranged at intervals on the flange edge of the linear track.

[0068] The inner end of the end cover 5 is detachably connected to the corresponding notch end face of the saddle body 1 through a plurality of connecting screws 6. In order to prevent the end cover 5 from scratching the corresponding notch end face of the saddle body 1 and to improve the sealing effect of the joint, a rubber pad with a thickness of about 3 mm is provided between the inner end of the end cover 5 and the corresponding notch end face.

[0069] The outer edges of the notches on both sides of the top of the end cover 5 are connected to the corresponding extension sections of the above-mentioned cover plate 2 in a detachable structure through multiple connecting bolts 7, and the outer ends of the end cover 5 are basically flush with the ends of the corresponding extension sections of the cover plate 2. In order to improve the sealing effect of the joint, a rubber pad 4 with a thickness of about 3 mm is arranged between the outer edges of the notches of the end cover 5 and the corresponding extension sections of the cover plate 2.

[0070] In this way, the end covers 5 connected to the two ends of the saddle body 1 in the longitudinal direction respectively form a U-shaped profile extension structure at the corresponding ends of the saddle body 1 to match the saddle groove 11 in the longitudinal direction. A main cable installation channel is enclosed between each set of end covers 5 and the corresponding extension section of the cover plate 2.

[0071] Example 3

[0072] The utility model is a saddle groove protection structure used in the construction period of a suspension bridge, which comprises a saddle body and a covering plate.

[0073] Specifically, the saddle body is a main cable saddle in a suspension bridge structure, and the upper part of the saddle body has a saddle groove for passing the main cable.

[0074] During the construction of a suspension bridge, the main cable is installed in the saddle groove along the longitudinal direction of the saddle body, and multiple tie rods are installed in the tie rod holes corresponding to each other in the horizontal width direction of the upper part of the saddle groove, and are locked by multiple zinc blocks arranged in the saddle groove. Before the saddle cover is connected, the saddle groove on the saddle body and the main cable installed in the saddle groove (including the structure for locking the main cable) are shielded and protected by a covering plate to reduce the intrusion of corrosive substances into the saddle groove.

[0075] The covering plate is a steel plate with a pattern structure. To ensure the structural strength, the minimum thickness of the covering plate (i.e. the thickness of the main part, excluding the height of the pattern protrusion) is about 8mm.

[0076] The dimension of the covering plate in the transverse direction basically matches the dimension between the outer edges of the notches on both sides of the saddle groove of the saddle body in the transverse direction. The dimension of the covering plate in the longitudinal direction basically matches the dimension between the end faces of the notches on both ends of the saddle groove of the saddle body in the longitudinal direction.

[0077] The cover plate of the above structure has two side edges corresponding to the outer edges of the notches on both sides of the saddle groove in the horizontal width direction, and the outer edges of the edge of the cover plate are within the coverage range of the outer edges of the notches on the sides (at most flush with the outer edges of the outer edges of the notches on the sides), so the cover plate is an arc-shaped structure along the contour trajectory of the upper notch of the saddle groove in the longitudinal direction. After the cover plate of the above structure is seated in place at the outer edges of the notches on both sides of the saddle groove through the two side edges, the two ends in the longitudinal direction should be basically flush with the end faces of the notches on both ends of the saddle groove.

[0078] After the covering plate of the above structure is seated in place at the outer edges of the grooves on both sides of the saddle groove through the side edges, it is connected to the corresponding outer edges of the grooves of the saddle groove in a detachable structure at the side edges in the horizontal width direction through multiple connecting screws. The connecting screws adopt a countersunk structure, which requires the screw holes on the covering plate to adopt a countersunk structure.

[0079] In the above-mentioned connection structure between the cover plate and the saddle body, in order to prevent the cover plate from scratching the outer edges of the notches on both sides of the saddle groove and improve the sealing effect of the joint, a rubber pad with a thickness of about 3 mm is provided at the outer edges of the notches of the saddle groove, and the edges of the cover plate in the horizontal width direction are seated on the outer edges of the corresponding notches of the saddle groove through the corresponding rubber pads. Of course, the connection screws connecting the cover plate and the saddle body should pass through the rubber pads.

[0080] Through the above structure, a covering plate capable of shielding the saddle groove (including the main cable threading structure in the saddle groove) in the top view direction of the saddle body is connected to the top of the saddle body in a detachable structure. The saddle groove and the main cable threaded therein are shielded and protected in the top view direction of the saddle body by the covering plate, and the main cable threaded therein is located below the covering plate.

[0081] Example 4

[0082] The utility model is a saddle groove protection structure (or a temporary protection structure) used in the construction period of a suspension bridge, which comprises a saddle body and a covering plate.

[0083] Specifically, the saddle body is a main cable saddle in a suspension bridge structure, and the upper part of the saddle body has a saddle groove for passing the main cable.

[0084] During the construction of a suspension bridge, the main cable is installed in the saddle groove along the longitudinal direction of the saddle body, and multiple tie rods are installed in the tie rod holes corresponding to each other in the horizontal direction of the upper part of the saddle groove, and locked by multiple zinc blocks arranged in the saddle groove. Before the saddle cover is connected, the saddle groove on the saddle body and the main cable installed in the saddle groove (including the structure for locking the main cable) are shielded and protected by a covering plate to reduce the intrusion of corrosive substances into the saddle groove.

[0085] The cover plate is a steel plate with a single-sided pattern structure, that is, one side of the cover plate is a smooth structure and the other side is a pattern structure. To ensure structural strength, the minimum thickness of the cover plate (i.e. the thickness of the main part, excluding the height of the pattern protrusion) is about 7mm.

[0086] The dimension of the covering plate in the transverse direction substantially matches the dimension between the outer edges of the notches on both sides of the saddle groove of the saddle body in the transverse direction. The dimension of the covering plate in the longitudinal direction is greater than the dimension between the end faces of the notches on both ends of the saddle groove of the saddle body in the longitudinal direction.

[0087] The covering plate of the above structure has two side edges corresponding to the outer edges of the notches on both sides of the saddle groove in the horizontal width direction, and the outer edges of the side edges of the covering plate are within the coverage range of the outer edges of the notches on the sides (at most, they are flush with the outer edges of the outer edges of the notches on the sides). Therefore, the covering plate is an arc-shaped structure along the contour trajectory of the upper notch of the saddle groove in the longitudinal direction. Of course, in order to ensure the stability of the combination of the covering plate and the outer edges of the notches of the saddle groove, the smooth side of the covering plate in the connection structure with the saddle body should be used as the combination surface for the top of the saddle body, and the patterned side should be used as the anti-slip bearing surface facing upward, which is opposite to the saddle body and can be stepped on during construction. After the covering plate of the above structure is seated in place at the outer edges of the notches on both sides of the saddle groove through the two side edges, the two ends in the longitudinal direction should extend out of the notch end faces of the saddle groove to further increase the shielding and protection effect.

[0088] After the cover plate of the above structure is seated at the outer edges of the two side notches of the saddle groove through the two side edges, it is connected to the corresponding outer edges of the notches of the saddle groove in a detachable structure through multiple connecting screws at the two side edges in the horizontal width direction.

[0089] Through the above structure, a covering plate capable of shielding the saddle groove (including the main cable threading structure in the saddle groove) in the top view direction of the saddle body is connected to the top of the saddle body in a detachable structure. The saddle groove and the main cable threaded therein are shielded and protected in the top view direction of the saddle body by the covering plate, and the main cable threaded therein is located below the covering plate.

[0090] The above embodiments are only used to illustrate the present invention, but not to limit it.

[0091] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the above embodiments may still be modified, or some of the technical features may be replaced by equivalents. For example, the saddle body adopts a loose-cable saddle in a suspension bridge structure. Since the saddle groove of the loose-cable saddle is a gradually expanding structure in the longitudinal direction, the horizontal width of the cover plate in the longitudinal direction is also a gradually expanding structure that matches the structure. For example, the end cover shell is formed by an engineering plastic structure, etc. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the present invention.
