Description

Technical Field

[0001] The invention relates to the technical field of steel tube arch rib installation, and in particular to a steel tube arch rib ectopically assembled integral transverse movement device, system and installation method. Background Art

[0002] In the field of bridge engineering, steel tube concrete arch bridges are increasingly widely used in my country's modern bridge engineering construction due to their stable and beautiful structure, good economic benefits and environmental protection, short construction period, wide applicability, and excellent wind and earthquake resistance.

[0003] Arch rib installation is a key process in the construction of steel tube concrete arch bridges. The accuracy of its construction will have a direct impact on the linear quality of the entire bridge. At present, most of the steel tube concrete arch bridges that have been built and are under construction in China use cable hoisting and assembly method, cantilever vertical rotation method, integral lifting method or car crane lifting method for arch rib construction. However, no matter which of the above construction methods is used, there are corresponding requirements for site conditions. It is impossible to lift the arch rib to the design axis at one time under specific environmental conditions. The specific reasons are as follows:

[0004] Cable hoisting cantilever assembly method: Although the existing technology can realize the lateral movement of the single arch rib hoisting weight, the lateral movement of the weight after hoisting further increases the complexity of the tower force, affects the cables inserted through the tower, and thus causes the elevation change of the installed segment. It raises new problems for the construction and construction control of the steel tube arch rib, and even has a negative impact on the line shape of the completed bridge.

[0005] Lifting method using automobile crane: This type of construction method is convenient and flexible, but it is more demanding on the entire construction site. During operation, additional river filling or hardening treatment is required in the inner field of the bridge site. At the same time, due to the limited lifting radius of ordinary cranes, higher-performance equipment must be rented when lifting large-tonnage arch ribs. Combined with site treatment, this type of construction method will dramatically increase the construction investment of the project.

[0006] Cantilever vertical rotation method / integral lifting method: Although this method simplifies the construction process, it can only adjust the elevation of the arch rib. Before implementation, the arch rib needs to be positioned to the design axis in advance, which is difficult to adapt to the needs of eccentric lifting conditions of the arch rib.

[0007] From the above, it can be seen that during the construction of traditional large-span steel tube concrete arch bridges, the arch ribs are hoisted and installed by multiple segments. For the hoisting and installation of the arch rib segments, if there is limited hoisting space at the arch bridge site, complex hoisting conditions, difficult cost control, cumbersome installation procedures and other factors, in such projects with relatively complex construction environments, it is often inevitable that the traditional car lifting or cable hoisting system cannot hoist the arch ribs to the design axis at one time due to limited site conditions, resulting in the arch ribs being unable to be hoisted and installed to the design position at one time, and the construction is complex and the period is long. If the hoisting space at the arch bridge site is limited and the hoisting conditions are complex, if the cable crane does not have the conditions to move laterally along the bridge with load, and when installing the middle arch rib segment of the arch rib, the arch rib segment to be installed needs to be located in the direction of the bridge axis, then when hoisting the arch rib segment to be installed, the arch rib segment to be installed and the installed segment will inevitably have a spatial position conflict in the vertical direction, and the hoisting channel of the arch rib segment to be installed will be blocked, affecting the construction and installation of the arch rib segment of the entire arch bridge.

[0008] Moreover, when the arch rib is moved laterally nowadays, the construction operation is rather arbitrary, and there is no unified and standardized transverse installation equipment and transverse movement method. In addition, the arch rib transverse movement segment is large in size and heavy in weight, so the entire transverse movement is difficult. In the transverse movement process, there will inevitably be problems such as complicated transverse movement process, unstable arch rib transverse movement segment, slow transverse movement speed, etc. Moreover, after the arch rib transverse movement is in place, the arch rib transverse movement segment is not easy to support, and the arch rib transverse movement segment will inevitably be deformed or even damaged during the removal process. Summary of the invention

[0096] Example 3

[0097] This embodiment provides a method for lateral installation of steel pipe arch ribs in situ assembly, including the following steps:

[0098] S1, hoisting the arch rib segment 11 to the same elevation on one side of the designed position of the arch rib segment 11, so that the lower chord tube of the arch rib segment 11 is located in the corresponding arch rib clamp base 6, and connecting the arch rib clamp base 6 through the arch rib clamp upper cover 7 so that the lower chord tube of the arch rib segment 11 is fixed; wherein, the arch rib clamp base 6 and the arch rib clamp upper cover 7 can make the lower chord tube adapt to the line shape of the arch rib segment 11 at the designed position of the arch rib segment 11;

[0099] S2, after all the arch rib segments 11 to be installed are hoisted to the same elevation on one side corresponding to the designed position of the arch rib segment 11 and meet the linear shape, the adjacent arch rib segments 11 to be installed are connected to form an arch rib as a whole, that is, the arch rib segments 11 are closed;

[0100] S3. Move the arch rib as a whole to the designed position of the arch rib. Figure 5 As shown, the lateral movement installation is completed.

[0101] The method for lateral installation of the steel tube arch rib in situ assembly is described in this embodiment. The arch rib segment 11 is hoisted to the same elevation on one side of the designed position of the arch rib segment 11. Figure 5 The left side and Figure 8 As shown, the arch rib hoop base 6 and the arch rib hoop upper cover 7 make the lower chord tube adapt to the line shape of the arch rib segment 11 at the design position of the arch rib segment 11, thereby ensuring that the line shape and elevation of the arch rib segment 11 are the same as the design before the lateral movement; then the adjacent arch rib segments 11 to be installed are connected to form an arch rib as a whole, so that the line shape and elevation of the arch rib as a whole are the same as the design; then the arch rib as a whole is lateral moved to the arch rib design position, as shown in FIG. Figure 7 and Figure 8As shown; complete the lateral installation, such as Figure 6 As shown; the arch rib installation is efficient, high quality, and less restricted by space.

[0102] The lateral installation of the arch ribs is performed by using the steel tube arch rib ectopic assembly integral lateral installation system described in Example 2;

[0103] Before step S1, the pre-processed bulk components are transported to the bridge site and installed from bottom to top. Specifically, after the installation of the transverse bracket 19 and the non-transverse assembly bracket 20 is completed, the transverse bottom beam 1 is hoisted and welded to the top of the transverse bracket 19; if the transverse distance is long, the transverse bottom beam extension bolts and node plate joints 14 can be used to connect a section of the transverse bottom beam 15 to ensure the continuity of the entire transverse process. Figure 7 and Figure 8 As shown, when an existing simply supported bridge such as a T-beam is transformed into an arch bridge, the non-transverse assembly bracket 20 can be supported above the existing T-beam, and the transverse bracket 19 can be partially supported on the existing T-beam, which can reduce the erection height.

[0104] Then, the transverse sliding beam 5, the arch rib clamp base 6, the reaction frame 2 and the pushing mechanism are hoisted onto the transverse bottom beam 1 and fixed respectively; wherein, the transverse sliding beam 5 and the transverse bottom beam 1 are fixedly connected by the sliding fixing bolts 3 passing through the top circular hole 18 of the transverse bottom beam and the bottom circular hole 17 of the transverse sliding beam; the arch rib clamp base 6 can make the lower chord tube adapt to the linear shape of the arch rib segment 11 at the corresponding design position of the arch rib segment 11; preferably, the arch rib clamp base 6 is welded to the transverse sliding beam 5 in advance and then hoisted together to ensure the linearity of the arch rib and reduce high-altitude operations; the pushing mechanism is an intelligent synchronous jack 4, and the reaction frame 2 is detachably connected to the transverse bottom beam 1 by bolts, and can be connected using the top circular hole 18 of the transverse bottom beam on the transverse bottom beam 1, which is shared with the sliding fixing bolts 3, which can reduce the need to open holes on the transverse bottom beam 1 and reduce the need to further strengthen the transverse bottom beam 1, thereby saving costs. After the transverse sliding beam 5 is installed, the transverse sliding beam anti-slip device 12 is installed, and the transverse sliding beam anti-slip device 12 is connected to the transverse sliding beam 5 by bolts. When the reaction frame 2 and the jacking mechanism are installed for the first time, the jacking mechanism is tested to check the synchronization of the jacking mechanism at each position to ensure that the displacement of each point of the arch rib can be kept synchronous when the arch rib moves horizontally as a whole.

[0105] The arch rib hoop base 6 is hoisted and fixed on the top of the non-transverse assembly bracket 20; the arch rib hoop base 6 can be fixed on the non-transverse assembly bracket 20 by welding, bolt connection or other connection methods.

[0106] After completing the assembly of the components of the above-mentioned transverse shifting device, check the integrity of each component to ensure that it can meet the linear and elevation requirements of the arch rib.

[0107] In step S1, the arch rib segment 11 is hoisted into the corresponding arch rib clamp base 6, and the arch rib clamp base 6 is connected through the arch rib clamp upper cover 7 to fix the lower chord tube of the arch rib segment 11, that is, the arch rib clamp upper cover 7 is buckled on the arch rib lower chord tube and fixed by the arch rib clamp fixing bolt 8; then the upper chord tube of the arch rib segment 11 and the transverse sliding beam 5 are connected through the reinforcement mechanism, that is, one end of the arch rib cable 10 is connected to the arch rib cable anchoring ear plate 9 on the transverse sliding beam 5, and the other end is connected to the upper chord tube of the arch rib segment 11, forming Figure 1 In the state shown, the fixation of the corresponding arch rib segment 11 is completed. After the fixation is completed, the installation hanging point of the arch rib segment 11 can be released.

[0108] In step S2, after all the arch rib segments 11 to be installed are hoisted to the same elevation on one side of the design position corresponding to the arch rib segment 11 and meet the linear shape, the adjacent arch rib segments 11 to be installed are connected on the non-transverse assembly bracket 20 and the transverse bracket 19 to form an arch rib as a whole, and then the arch rib hoop base 6 and the arch rib hoop upper cover 7 on the top of the non-transverse assembly bracket 20 are removed, wherein the arch rib hoop base 6 can be removed by cutting;

[0109] In step S3, the corresponding sliding fixing bolt 3 is loosened from the circular hole 17 at the bottom of the transverse sliding beam, and then the loosened sliding fixing bolt 3 is inserted into the waist circular hole 16 at the bottom of the transverse sliding beam and the circular hole 18 at the top of the transverse bottom beam, so that the sliding fixing bolt 3 can slide along the length direction of the corresponding waist circular hole 16 at the bottom of the transverse sliding beam; then the arch rib is pushed and displaced laterally by a stroke as a whole through the pushing mechanism above all the transverse brackets 19; then the sliding fixing bolt 3 is loosened from the corresponding circular hole 18 at the top of the transverse bottom beam and installed in the circular hole 18 at the top of the transverse bottom beam one stroke ahead in the transverse direction, and the reaction frame 2 and the pushing mechanism are moved forward one stroke and then installed, and the pushing operation of the pushing mechanism and the installation operation of the sliding fixing bolt 3, the reaction frame 2 and the pushing mechanism after moving forward one stroke are repeated until the arch rib as a whole reaches the designed position of the arch rib, and the transverse installation is completed.

[0110] In step S3, the single displacement stroke is 15cm. After each single displacement stroke, the reaction frame 2 and the intelligent synchronous jack 4 need to be re-adjusted. The process is continuously observed and verified by the total station to ensure that the arch ribs formed by all the arch rib segments currently moving synchronously move as a whole. During the process, the single intelligent synchronous jack 4 can be adjusted by moving horizontally. The sliding fixing bolt 3 on the waist round hole 16 at the bottom of the horizontal sliding beam needs to be loosened for each single horizontal displacement stroke, and then installed in the waist round hole 16 at the bottom of the horizontal sliding beam in the horizontal displacement direction in the previous stroke, that is, the position of the circular hole 18 at the top of the connected horizontal bottom beam needs to be changed to ensure that the sliding fixing bolt 3 always moves in the waist round hole 16 at the bottom of the horizontal sliding beam of the horizontal sliding beam 5 during the sliding process, and finally moves horizontally to a position with equal margins to the part to be installed or the arch rib design position. And when the sliding fixing bolt 3 moves in the waist round hole 16 at the bottom of the horizontal sliding beam, the sliding fixing bolt 3 can be slightly loosened to ensure the smoothness of sliding.

[0111] It is further explained that during the overall transverse movement of the arch rib, the transverse sliding beam anti-slip device and the sliding fixing bolt 3 located in the waist-round hole 16 at the bottom of the transverse sliding beam both play a role of limiting and guiding. During the movement of the transverse sliding beam 5, the spatial position of the sliding fixing bolt 3 needs to be continuously adjusted to ensure that it is always located in the waist-round hole 16 at the bottom of the transverse sliding beam and remains slightly loose until it is tightened after the transverse movement construction is completed.

[0112] In this embodiment, the above hoisting can be carried out by a crane or other lifting equipment. The lateral installation of the arch ribs is performed by using the steel pipe arch rib lateral assembly integral lateral installation system described in Example 2, which is safer and more efficient.

[0113] In projects with relatively complex construction environments, it is often inevitable that the traditional automobile lifting or cable lifting system cannot lift the arch rib to the design axis at one time due to limited site. For this reason, the present invention proposes a method for lateral assembly of steel tube arch ribs, and realizes the lateral assembly of arch ribs through the self-developed lateral assembly of steel tube arch ribs. After the arch rib segments 11 are lifted and installed to a suitable position, they are closed into an arch rib as a whole, and then transversely moved to a position with equal margins to the part to be installed or the design position of the arch rib, effectively solving the problems of limited site space, complex lifting conditions, high transverse movement costs, and simplifying the entire arch rib installation process. The lateral assembly of steel tube arch ribs and the lateral assembly of steel tube arch ribs are suitable for various environmental conditions. The site conditions required for the use of the equipment are not high, and the time required for the preliminary work preparation is relatively short, which can achieve the purpose of convenient and efficient transverse movement of arch ribs with low safety risks. A method for installing steel tube arch ribs by ectopic assembly and overall transverse movement, which comprises first hoisting the arch rib segments one by one to a temporary transverse movement support platform to complete the docking assembly, and then using a steel tube arch rib ectopic assembly and overall transverse movement device to push the arch ribs step by step to the design axis, thereby solving the problem of "under specific environmental constraints and the inability to lift the arch ribs to the design axis in a safe, efficient, time-compressed and economically efficient manner through existing hoisting technology".

[0114] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
