Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of bridge component construction, and more specifically, relates to a saddle cover and a construction method thereof. Background Art
[0002] The saddle cover of a suspension bridge is a protective device to protect the main cable saddle from external environmental interference. Since the saddle cover of the suspension bridge can ensure the tightness of the saddle chamber, the dehumidification system in the saddle chamber can operate effectively. At the same time, the landscape lights on the cable tower of the suspension bridge are usually installed on the saddle cover, which requires high quality and appearance of the saddle cover. Since the saddle cover is at the highest point of the cable tower and the construction is interfered by the main cable, the existing saddle covers mostly adopt casting molding and steel structure molding. For the saddle cover formed by casting, it is difficult to ensure the construction joints and the quality of concrete pouring due to the limited amount of concrete lifted each time, and it is extremely easy to appear cracks and honeycombed pitted surfaces, resulting in low aesthetics of the saddle cover. The steel structure saddle cover is divided into two types: integral hoisting or block hoisting. The integral hoisting has a large weight, difficult control of hoisting deformation, and high risk of high-altitude hoisting. The block hoisting needs to be assembled and welded at the top of the tower, and the on-site welding quality is not easy to guarantee. In addition, the durability of the steel structure is poor and it is easy to be corroded by rain, and the later maintenance workload is large. Summary of the Invention
[0003] Aiming at the above defects or improvement requirements of the prior art, the invention provides a saddle cover and a construction method thereof, aiming to reduce the structural self-weight of the saddle cover, reduce the hoisting difficulty, and at the same time ensure the sealing performance and durability of the saddle cover.

[0037] Please refer to Figures 1 to 5 As shown, the present invention provides a saddle cover 10, which includes a saddle cover sub-module 11, a flange connection structure 12, a fixed connection structure 13, a support structure 14, a waterproof member 15, and a cable outlet 161.
[0038] The saddle cover module 11 is prefabricated from high-performance concrete. It is not difficult to understand that due to the advantages of high strength, good impermeability and good durability of high-performance concrete, the prefabrication of the saddle cover module 11 with high-performance concrete can reduce the thickness of the saddle cover module 11 on the premise of ensuring strength, impermeability and durability, thereby reducing the mass of the saddle cover module 11 for easy transportation and hoisting. At the same time, high-performance concrete has good crack resistance, which enables the saddle cover module 11 to avoid cracking due to external factors and further prevent rainwater from entering the saddle 10 through the cracks. In addition, due to the high density and low unconnected porosity of high-performance concrete, the surface of the saddle cover module 11 prefabricated from high-performance concrete is delicate and textured, which can improve the aesthetics of the saddle cover module 11. Further, a plurality of saddle cover modules 11 are assembled to form the saddle 10. The advantage of this setting is that the mass of each saddle cover module 11 is light and the volume is small, which is convenient for hoisting the saddle cover module 11. At the same time, since the saddle cover module 11 is made of high-performance concrete, the saddle cover module 11 can be prefabricated in advance, thus avoiding the continuous pouring construction of the concrete 152 and affecting the construction period.
[0039] It should be noted that since the saddle 10 needs to protect the cable saddle from external factors, in this embodiment, the saddle 10 is in a semi-cylindrical ring shape. The cutting surface of the semi-cylindrical ring-shaped saddle 10 is connected to the surface of the cable tower 20. The cylindrical surface of the semi-cylindrical ring-shaped saddle 10 is in an arc shape outward. When it rains, rainwater can slide down from the top of the saddle 10 to avoid the influence on the cable saddle caused by the long-term accumulation of rainwater entering the saddle 10. The side arms of a plurality of saddle 10 sub-modules are spliced with each other to form the saddle 10, and the splicing direction of the plurality of saddle 10 sub-modules is the axial direction of the saddle 10. It is worth noting that the present invention is not limited thereto. In other embodiments, the saddle 10 can also be triangular prism-shaped, and the present invention does not make specific limitations here as long as the shape of the saddle 10 is convenient for drainage.
[0040] The flange connection structure 12 is provided on the side wall of the saddle cover module 11, and adjacent two saddle cover modules 11 are spliced through the flange connection structure 12. The advantage of this setting is that since adjacent saddle cover modules 11 are connected through the side wall and the flange connection structure 12 is directly provided on the side wall of the saddle cover module 11, compared with setting the flange connection structure 12 on the inner wall or outer wall of the saddle cover module 11, it can be realized that only a shorter flange connection structure 12 can connect two saddle cover modules 11. In this way, it can be avoided that the flange connection structure 12 is too long and easy to break, resulting in the damage of the connection part. At the same time, the flange connection structure 12 can be hidden after the adjacent two saddle cover modules 11 are spliced to ensure the integrity and aesthetics of the saddle 10.
[0041] The fixed connection structure 13 is provided on the bottom surface of the saddle cover module 11, and this fixed connection structure 13 is used to form a fixed connection with the cable tower 20. Specifically, since the saddle cover module 11 is prefabricated, it is difficult to connect the saddle cover module 11 with the cable tower 20. In contrast, by placing concrete 152 on the top of the cable tower 20 to connect the saddle cover module 11 with the top of the cable tower 20, the advantage of using the fixed connection structure 13 is that the connection can be achieved quickly, avoiding the time required for the concrete 152 to solidify. At the same time, using the fixed connection structure 13 can ensure that the connection between the saddle cover module 11 and the top of the cable tower 20 is relatively smooth and has a higher cleanliness. In addition, after the saddle cover module 11 is connected to the top of the cable tower 20, the fixed connection structure 13 can be hidden, thereby ensuring the integrity and aesthetics of the saddle 10.
[0042] The support structure 14 is provided inside the saddle cover module 11, and this support structure 14 is used to support the inner walls on both sides of the saddle cover module 11. It is not difficult to understand that since the saddle cover module 11 is in a semi-cylindrical ring shape, when the saddle cover module 11 is being hoisted, the two sides of the saddle cover module 11 are prone to relative vibration. By providing support to the two sides of the saddle cover module 11 through the support structure 14, it is possible to prevent the saddle cover module 11 from being damaged due to vibration during hoisting.
[0043] The waterproof member 15 is provided on the outer walls of the flange connection structure 12 and the fixed connection structure 13, and this waterproof member 15 is used to form a waterproof layer. It is not difficult to understand that at the flange connection structure 12 is the splicing part of two adjacent saddle cover modules 11, and at the fixed connection structure 13 is the connection part between the saddle cover module 11 and the cable tower 20. Both of the above two places are where there are gaps in the saddle 10. By forming a waterproof layer through the waterproof member 15 here, it is possible to prevent external factors such as rainwater from invading and corroding the saddle.
[0044] The cable outlet 161 is provided on the opposite sides of the saddle 10, and this cable outlet 161 is used for the suspension cable to extend in and out. Specifically, on one side of the cable outlet 161 on both sides of the saddle 10, the suspension cable extends in, and on the other side, the suspension cable extends out. It can be understood that setting the cable outlet 161 enables the suspension cable to enter the saddle 10, contact the saddle, and then come out of the saddle 10, so that the suspension cable can connect the suspension bridge in series.
[0045] It can be understood that the saddle cover 10 of the present application is formed by splicing saddle cover sub-modules 11 prefabricated with high-performance concrete, which can ensure a relatively light weight under the premise of the same strength, thus facilitating transportation and hoisting. At the same time, the saddle cover sub-modules 11 prefabricated with high-performance concrete have good weather resistance, crack resistance and aesthetics, which enables the saddle cover 10 to be used for a long time. The adjacent saddle cover sub-modules 11 are connected through the flange connection structure 12, the connection between the saddle cover sub-module 11 and the cable tower 20 is realized through the fixed connection structure 13, the saddle cover sub-module 11 is prevented from being damaged during transportation and hoisting through the support structure 14, the saddle cover 10 is waterproofed through the waterproof member 15, and the suspension cable is extended and retracted through the cable outlet 161. The saddle cover 10 of the present application is light in weight, convenient for hoisting and transportation, and has good sealing and durability.
[0046] In an embodiment, the flange connection structure 12 includes a steel plate 121 and an insertion rod 122. The steel plate 121 is embedded in the side wall of the saddle cover sub-module 11. The steel plate 121 is recessed with an insertion hole 1211 towards the inside of the saddle cover sub-module 11. The insertion rod 122 is used to be inserted into the insertion holes 1211 of two adjacent saddle cover sub-modules 11. A through threaded port 1212 is recessed on the inner side of the steel plate 121, and the threaded port 1212 can be screwed into by a bolt 123.
[0047] Specifically, since the side wall of the saddle cover sub-module 11 is provided with the steel plate 121, the two adjacent saddle cover sub-modules 11 can be attached through the steel plate 121, avoiding a large gap at the joint and preventing external factors such as rainwater from invading. Embedding the steel plate 121 into the saddle cover sub-module 11 can ensure the tightness of the connection between the steel plate 121 and the saddle cover sub-module 11. During actual operation, the steel plate 121 can be placed on both sides of the saddle cover sub-module 11 before the high-performance concrete used to manufacture the saddle cover sub-module 11 hardens. In this way, after the high-performance concrete hardens, the steel plate 121 and the saddle cover sub-module 11 can form an integral structure.
[0048] Furthermore, the steel plate 121 is provided with an insertion hole 1211 recessed toward the inside of the saddle cover submodule 11, and the insertion rod 122 is used to be inserted into the insertion holes 1211 of the two adjacent saddle cover submodules 11. That is to say, by inserting the insertion rod 122 into the insertion holes 1211 of the side walls of the two adjacent saddle cover submodules 11, the two saddle cover submodules 11 can be formed into an integral structure. Specifically, the insertion hole 1211 extends toward the inner side of the saddle cover submodule 11, and the insertion holes 1211 of the two adjacent saddle cover submodules 11 are correspondingly arranged. During actual installation, one end of the insertion rod 122 can be inserted into the insertion hole 1211 of one saddle cover submodule 11, and after the insertion, the other end of the insertion rod 122 can be inserted into the insertion hole 1211 of the other saddle cover submodule 11. It can be understood that by inserting an insertion rod 122 into two adjacent saddle cover sub-modules 11, it is possible to avoid the two adjacent saddle cover sub-modules 11 from being misaligned in the directions of the inside and outside of the saddle cover 10. At the same time, since the insertion rod 122 is inserted into the insertion hole 1211, this can prevent the insertion rod 122 from contacting external factors such as rainwater, and can prevent the insertion rod 122 from being corroded. In addition, after the two saddle cover sub-modules 11 are spliced together, the insertion rod 122 can be hidden, which can ensure the integrity and aesthetics of the saddle cover 10.
[0049] It should be noted that, in the present embodiment, the length of the insertion rod 122 is equal to the sum of the lengths of the two adjacent saddle cover 10 sub-modules. In this way, it is possible to avoid the insertion rod 122 from moving laterally from the insertion hole 1211 due to the shorter length of the insertion rod 122, and to avoid the insertion rod 122 being too long, so that the two adjacent saddle cover sub-modules 11 are supported by the insertion rod 122, resulting in the two steel plates 121 of the two adjacent saddle cover sub-modules 11 being unable to fit together.
[0050] Furthermore, a through threaded opening 1212 is recessed on the inner side of the steel plate 121 , and the threaded opening 1212 can be used for screwing the bolt 123 into. Among them, the inner side of the steel plate 121 refers to the inner side of the saddle cover 10. Specifically, the steel plate 121 extends from the side wall of the saddle cover sub-module 11 to the inner side of the saddle cover 10. Since the steel plates 121 of the two adjacent saddle cover sub-modules 11 are provided with a through threaded opening 1212, by passing the bolt 123 through the two threaded openings 1212 and then locking it with a nut, it is possible to prevent the two adjacent saddle cover sub-modules 11 from moving away from each other in the direction of the insertion rod 122, thereby causing the spliced saddle cover 10 to fall apart. Since the threaded opening 1212 is arranged on the inner side of the steel plate 121, the bolt 123 cannot be seen from the outer side of the saddle cover 10. While ensuring the connection, the integrity and aesthetics of the saddle cover 10 are improved. At the same time, since a dehumidification device is provided inside the saddle cover 10, the bolt 123 can be kept in a dry environment for a long time, thereby ensuring the long-term use of the bolt 123.
[0051] In one embodiment, the waterproof member 15 includes a waterproof glue 151. A filling groove 111 is recessed in the outer wall of the saddle cover module 11. The filling groove 111 extends towards the side of the steel plate 121 first, and the filling groove 111 is for filling the waterproof glue 151. Specifically, since the flange connection structure 12 is provided on the side wall of the saddle cover module 11, it is necessary for the waterproof glue 151 to cover the outer wall of the saddle cover module 11. When using the waterproof glue 151 to ensure the waterproof effect, due to its adhesiveness, the waterproof glue 151 is not easily detached. The provision of the filling groove 111 for filling the waterproof glue 151 can increase the contact area between the waterproof glue 151 and the saddle cover module 11 to ensure the connection strength and prevent the waterproof glue 151 from detaching. In addition, since the waterproof glue 151 is filled in the filling groove 111, when subjected to external forces such as strong wind or rain, the waterproof glue 151 will only be subjected to external forces perpendicular to the outer wall of the saddle cover module 11, and it can be prevented from detaching due to external forces parallel to the outer wall of the saddle cover module 11.
[0052] Furthermore, after the filling groove 111 is filled with the waterproof glue 151, it is flush with the waterproof groove. Specifically, the color of the waterproof glue 151 is the same as that of the high-performance concrete. Since the waterproof glue 151 is flush after filling the waterproof groove, the adjacent saddle cover modules 11 tend to be integrated. In this way, the aesthetics of the saddle cover 10 can be ensured.
[0053] In one embodiment, the fixed connection structure 13 includes a connecting plate 131 which is embedded in the bottom surface of the saddle cover module 11, and a mating plate 132 which is provided on the cable tower 20 and is in contact with the connecting plate 131. Specifically, the surfaces of the connecting plate 131 and the mating plate 132 are both smooth and flat. By making the connecting plate 131 in contact with the mating plate 132, compared with the direct connection between the surface of the saddle cover module 11 and the cable tower 20, it can be avoided that the unevenness of the surface of the saddle cover module 11 or the cable tower 20 affects the tightness of the connection, and further prevents rainwater from intruding from this place.
[0054] Further, a connection hole 1311 is recessed in the connection plate 131, and a mating hole 1321 is recessed in the mating plate 132. The fixed connection structure 13 includes a connecting rod 133, and the connecting rod 133 is used to be inserted into the connection hole 1311 and the mating hole 1321. Specifically, the connection hole 1311 is recessed inward from the surface of the connection plate 131, the mating hole 1321 is recessed inward from the surface of the mating plate 132, and the positions of the connection hole 1311 and the mating hole 1321 correspond. During actual connection, one end of the connecting rod 133 needs to be inserted into the mating hole 1321 of the mating plate 132 first, and then the connection hole 1311 on the connection plate 131 is aligned with the other end of the connecting rod 133 and inserted to achieve connection. The advantage of this setting is that it can prevent the saddle cover module 11 from bending inward or spreading outward from the saddle cover 10. At the same time, since the connecting rod 133 is inserted into the connection plate 131, it can prevent the connecting rod 133 from being eroded due to external factors, ensuring the long-term use of the saddle cover 10, and at the same time, the connecting rod 133 can be hidden to ensure the integrity and aesthetics of the structure.
[0055] It should be noted that, in this embodiment, the connection hole 1311 penetrates through the connection plate 131 and extends into the interior of the saddle cover module 11, the mating hole 1321 penetrates through the mating plate 132 and extends into the interior of the cable tower 20, and a relatively long connecting rod 133 is provided to ensure the tightness of the connection between the saddle cover module 11 and the cable tower 20.
[0056] Further, anti-disengagement holes 1312 are correspondingly recessed on one side of the connection plate 131 and the mating plate 132. The fixed connection structure 13 includes an anti-disengagement rod 134, and the anti-disengagement rod 134 is inserted into the cable tower 20 from the anti-disengagement hole 1312. Specifically, threads are formed by recessing in the anti-disengagement hole 1312, and threads are provided on the surface of the anti-disengagement rod 134. By screwing the anti-disengagement rod 134 into the anti-disengagement hole 1312 and fixing it with a nut, it can prevent the saddle cover module 11 and the cable tower 20 from separating vertically.
[0057] In one embodiment, the waterproof member 15 includes concrete 152. A groove 21 is recessed in the bottom surface of the cable tower 20, and the fixed connection structure is arranged on the bottom surface of the groove 21, and the groove 21 is for filling the concrete 152. Specifically, after the saddle cover module 11 and the cable tower 20 are connected, the saddle cover module 11 is located in the groove 21. In this case, filling the concrete 152 in the groove 21 can enclose the fixed connection structure in the concrete convex to prevent the fixed connection structure from being damaged or eroded. At the same time, it can also ensure the tightness of the connection between the saddle cover module 11 and the cable tower 20. In addition, external factors such as rainwater cannot enter the interior of the saddle cover 10.
[0058] In one embodiment, the support structure 14 includes a fitting plate 145 for fitting to the inner wall of the saddle cover module 11. Specifically, the fitting plate 145 is arc-shaped and has the same shape as the saddle cover module 11. After the fitting plate 145 is fitted to the inner wall of the saddle cover module 11, the contact area between the fitting plate 145 and the saddle cover module 11 is maximized at this time, thereby providing better support for the saddle cover module 11. It is not difficult to understand that since the saddle cover module 11 is prefabricated, it is necessary to transport the saddle cover module 11 from the prefabrication factory to the construction site. Using this fitting plate can not only provide support when the saddle cover module 11 is hoisted, but also provide support for the saddle cover module 11 during transportation.
[0059] Furthermore, for the convenience of fixing the saddle cover module 11 during transportation and facilitating hoisting, in this embodiment, lifting points 144 are provided on the fitting plate. Specifically, there are four lifting points 144. The four lifting points 144 are grouped in two, and the two groups are respectively provided on both sides of the fitting plate. The two lifting points 144 in one group are provided on the front and back sides of the fitting plate. It is not difficult to understand that this can ensure stability during hoisting or transportation.
[0060] Furthermore, the support structure 14 includes a cross brace 141, a vertical brace 142, and a diagonal brace 143. The cross brace 141 is connected to both sides of the arc-shaped support, the vertical brace 142 is connected to the top of the arc-shaped support, and the diagonal brace 143 connects the cross braces 141 to form a triangular fixing structure. Specifically, the cross brace 141 transversely connects both sides of the fitting plate, the vertical brace 142 is connected to the top of the fitting plate and is connected to the cross brace 141, and the diagonal brace 143 is obliquely connected between two adjacent cross braces 141. The advantage of such a setting is that the cross brace 141 fixes both sides of the fitting plate and provides a limit when the two sides of the fitting plate approach or move away from each other. The vertical brace 142 can prevent the fitting plate from receiving the support force, so that the fitting plate can lift the saddle cover module 11. The combination of the diagonal brace 143 and the cross brace 141 forms a triangular structure, which can improve the stability of the support structure 14.
[0061] In one embodiment, the cable outlet 161 is formed by stacking a plurality of masonry units 16. It can be understood that stacking the masonry units 16 facilitates controlling the shape and size of the cable outlet 161. During actual stacking, only by partially cutting each masonry unit 16 can the shape and size of the cable outlet 161 formed by the plurality of masonry units 16 be variable. At the same time, compared with the cable outlet 161 made of concrete 152, its construction period is shorter.
[0062] Further, the outer surface of the masonry 16 is smeared with mortar. Specifically, putty is filled in the gap between the cable outlet 161 and the suspension cable, and the entire outer surface of the masonry 16 is smeared with mortar, so as to prevent rainwater from invading from the cable outlet 161 or the gap of the masonry 16, thereby corroding the saddle.
[0063] Please refer to Figure 6 As shown, the present invention also provides a construction method based on the above saddle cover 10, and this construction method includes the following steps:
[0064] S100. Design the outer shape of the saddle cover 10 and divide the saddle cover 10 into multiple saddle cover sub-modules 11.
[0065] Among them, when designing the outer shape of the saddle cover 10, due to the requirement of rapid drainage, in this embodiment, a semi-cylindrical ring, a curved surface shape, is used for drainage. This design is compared with the design of a slope for drainage, such as a prism shape and a prism shape. Since the semi-cylindrical ring is a curved surface, its structure is more stress-resistant and can be used in the high-wind environment at the top of the suspension bridge. When dividing the saddle cover 10, it is divided along the axial direction of the semi-cylindrical ring. In this way, it is ensured that the shapes of each saddle cover sub-module 11 are the same, which is convenient for batch prefabrication. In terms of the division length, the width of each saddle cover sub-module 11 is controlled within 4m. It is not difficult to understand that since the saddle cover sub-module 11 is prefabricated by a prefabrication factory, and there is a distance interval between the prefabrication factory and the suspension bridge, the prefabricated saddle cover sub-module 11 needs to be transported by a transport vehicle or a transport ship, and the loading width of the transport vehicle or the transport ship is generally less than 4m. In this way, it is convenient for the transportation of the saddle cover sub-module 11.
[0066] S200. Prefabricate the saddle cover sub-module 11 with high-performance concrete.
[0067] Among them, using high-performance concrete has the characteristic of being light in mass under the same strength, which can meet the weight reduction requirement of the saddle cover 10. In actual prefabrication, since high-performance concrete solidifies and forms relatively quickly, it enables the prefabricated saddle cover sub-module 11 to be obtained in a relatively short time.
[0068] S300. Transport and hoist the saddle cover sub-module 11 by using the support structure 14.
[0069] Specifically, during transportation and lifting, the two sides of the arc-shaped saddle cover sub-module 11 will move closer to or farther away from each other due to shaking, which causes the two sides of the saddle cover sub-module 11 to move relative to the top of the saddle cover sub-module 11 and bend. During long-term movement, the connection between the two sides of the saddle cover sub-module 11 and the top will exceed the strain limit due to repeated bending, thereby causing the connection between the two sides of the saddle cover sub-module 11 and the top to break. The support structure 14 can prevent the two sides of the saddle cover sub-module 11 from moving closer to or farther away from each other due to shaking, thereby preventing the saddle cover sub-module 11 from breaking.
[0070] S300, connecting two adjacent saddle cover sub-modules 11 using a flange connection structure 12, and connecting the saddle cover sub-module 11 and the cable tower 20 using a fixed connection structure 13.
[0071] Specifically, during the actual connection, in order to ensure the tightness of the connection, the two adjacent saddle cover modules 11 are first connected to the tower 20, and then the flange connection structure 12 is used to connect the two adjacent saddle cover modules 11, that is, connect from bottom to top to ensure the tightness of the connection to the maximum extent.
[0072] S400 , the saddle cover 10 is waterproofed using concrete 152 and waterproof glue 151 .
[0073] Specifically, the filling grooves 111 of two adjacent saddle cover modules 11 are filled with waterproof glue 151. Since the waterproof glue 151 has a certain degree of adhesion, it can ensure waterproofness while also connecting the two saddle cover modules 11 to a certain extent. Furthermore, since the top of the cable tower 20 is at a higher position and is prone to encountering a larger airflow, concrete 152 is filled in the groove 21. In this way, after the concrete 152 solidifies, the saddle cover module 11 and the cable tower 20 are connected as a whole, which can ensure the long-term stability of the saddle cover module 11 and the cable tower 20.
