Description

Technical Field

[0002] The construction of subway stations is an important part of subway lines. The traditional all-concrete cast-in-place method can no longer meet the current requirements of efficient construction.

DETAILED DESCRIPTION

[0031] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0032] This embodiment provides a composite station construction system suitable for assembling composite subway stations, which can improve construction efficiency and shorten the construction period. The system can assemble single-story stations, double-story stations, three-story stations, four-story stations, etc.

[0033] A composite subway station consists of side walls, central columns, longitudinal beams, and a roof slab. The side walls and central columns are vertically distributed on both sides of the station, the longitudinal beams are located between two adjacent central columns, and the roof slab is located between the side walls and longitudinal beams.

[0034] For stations with two or more floors, the roof is divided into the middle roof located on the lower floor and the roof located on the upper floor; the longitudinal beams are divided into the middle longitudinal beams located on the lower floor and the top longitudinal beams located on the upper floor.

[0035] Figure 1 The figure shows a double-deck station. The superimposed subway station includes: side wall blocks 91, center columns 92, center top plates 93, top plates 94, center longitudinal beams 95, top longitudinal beams 96, and bottom plates 97. During the construction process, the bottom plate 97 of the platform and the bottom longitudinal beam 98 located in the middle of the bottom plate 97 are cast first. The longitudinal direction is the length of the platform and also the direction of travel. Along the longitudinal direction, multiple side wall blocks 91 are spliced in sequence to form the side walls, multiple center columns 92 are arranged at intervals, and multiple center longitudinal beams 95 are spliced in sequence, and the center longitudinal beams 95 are overlapped on two adjacent center columns 92. The center top plates 93 are overlapped between the side wall blocks 91 and the center longitudinal beams 95 in the transverse direction, and multiple center top plates 93 are spliced in sequence in the longitudinal direction. The above-mentioned side wall blocks 91, center columns 92, center longitudinal beams 95, and center top plates 93 constitute the lower structure of the station. After the construction of the lower structure is completed, the upper structure of the station begins to be built.

[0036] In the station's upper structure, upper center columns 92 are spaced longitudinally above the center longitudinal beams 95, and top longitudinal beams 96 are installed between adjacent upper center columns 92. Upper side wall blocks 91 are sequentially arranged on top of the lower side wall blocks 91, and top panels 94 are installed between the upper side wall blocks 91 and the top longitudinal beams 96. The top panels 94 are sequentially spliced longitudinally.

[0037] Figure 2 The station shown here is a three-story station. Similar to a two-story station, the station is divided into a top structure, a middle structure, and a bottom structure. The bottom structure is the same as the lower structure in a two-story station, while the middle and top structures refer to the upper structures in a two-story station, respectively.

[0038] like Figure 3 As shown, the assembly trolley 10 is used to construct the lower structure. After the construction is completed or after the construction meets certain conditions, the assembly trolley 10 is used to construct the upper structure.

[0039] The construction system includes a first assembly trolley, a second assembly trolley and a center column mounting frame.

[0040] In the above description, the bottom longitudinal beams 98 divide the platform floor 97 into two platform areas (referred to as station areas). A track extending longitudinally along the floor 97 of each station area is provided. A first assembly trolley and a second assembly trolley are installed in each station area and can travel along the track. The first and second assembly trolleys are used to assemble the side wall blocks, longitudinal beams, and roof panels in the two station areas, respectively.

[0042] The first assembly trolley and the second assembly trolley may adopt the same structure, or they may be slightly different according to needs.

[0043] The first assembly trolley includes a frame, a wheel-rail running gear, a sidewall mounting device, a longitudinal beam mounting device, and a roof mounting device. The wheel-rail running gear is located at the bottom of the first assembly trolley and is installed on a track in an area on one side of the station floor (i.e., a station area), and can travel longitudinally along the track. The sidewall mounting device is used to carry sidewall blocks and sequentially connect the sidewall blocks to form the side wall of the station. The roof mounting device is used to carry roof panels and overlap them between the sidewall blocks and the longitudinal beams. Multiple roof panels are arranged in sequence along the longitudinal direction.

[0044] The second assembly trolley includes: a frame, a wheel-rail running device, a side wall mounting device, a longitudinal beam mounting device, and a roof mounting device; the wheel-rail running device is located at the bottom of the second assembly trolley and is installed on the track in the area on the other side of the station floor (i.e., the other station area), and can travel longitudinally along the track; the side wall mounting device is used to carry the side wall blocks and sequentially splice the side wall blocks to the other side of the station to form the side wall; the roof mounting device is used to carry the roof panels and overlap the roof panels between the side wall blocks and the longitudinal beams; multiple roof panels are arranged in sequence along the longitudinal direction; At least one of the first assembly trolley and the second assembly trolley is provided with a longitudinal beam installation device, which is used to carry the longitudinal beam and overlap the longitudinal beam between two adjacent central columns.

[0045] The technical solution provided in this embodiment adopts the cooperation of the first assembly trolley, the second assembly trolley and the center column mounting frame to realize the assembly of the side wall blocks, center columns, longitudinal beams and top plate of the station; wherein, the bottom of the center column mounting frame is provided with running wheels, which can walk on the station floor; the center column mounting frame is used to carry the center column and install the center column to the target position; each center column is arranged in the middle of the station along the longitudinal interval; the first assembly trolley includes: a frame, a wheel-rail running device, a side wall mounting device, a longitudinal beam mounting device and a top plate mounting device; the wheel-rail running device is located at the bottom of the first assembly trolley, and is set on the track in the area on one side of the station floor, and can walk longitudinally along the track; the side wall mounting device is used to carry the side wall blocks, and splice the side wall blocks to one side of the station in sequence to form a side wall; the top plate mounting device The device is used to carry the top plate and overlap the top plate between the side wall blocks and the longitudinal beams; multiple top plates are arranged in sequence along the longitudinal direction; the second assembly trolley includes: a frame, a wheel-rail running device, a side wall mounting device, a longitudinal beam mounting device and a top plate mounting device; the wheel-rail running device is located at the bottom of the second assembly trolley, and is set on the track in the area on the other side of the station floor, and can move longitudinally along the track; the side wall mounting device is used to carry the side wall blocks, and splice the side wall blocks in sequence to the other side of the station to form a side wall; the top plate mounting device is used to carry the top plate and overlap the top plate between the side wall blocks and the longitudinal beams; multiple top plates are arranged in sequence along the longitudinal direction; at least one of the first assembly trolley and the second assembly trolley is provided with a longitudinal beam mounting device, and the longitudinal beam mounting device is used to carry the longitudinal beam and overlap the longitudinal beam between two adjacent center columns. The above scheme realizes the assembly of the composite station, and the first assembly trolley and the second assembly trolley are used to assemble the two station areas respectively, working in parallel, which can multiply the construction efficiency.

[0046] The construction system provided in this embodiment is particularly suitable for scenarios with steel temporary beams. The presence of these beams precludes the use of gantry cranes for assembling the various structures. An open-air opening is provided at one end of the steel temporary beam, through which components are hoisted onto a trolley using a gantry crane. The trolley then allows the various structures to be transported and assembled autonomously beneath the steel temporary beam.

[0047] Based on the above technical solution, in this embodiment, the first assembly trolley and the second assembly trolley can adopt the same structure, and their frame, wheel-rail running device, side wall mounting device, longitudinal beam mounting device and top plate mounting device adopt the same structure.

[0048] Alternatively, the first assembly trolley and the second assembly trolley use the same frame, wheel-rail running device, side wall mounting device and top plate mounting device, and at least one of the first assembly trolley and the second assembly trolley is provided with a longitudinal beam mounting device, which is used to carry the longitudinal beam and overlap the longitudinal beam between two adjacent center columns.

[0049] This embodiment also provides specific implementation methods: like Figures 4 to 11 As shown, after the station floor 97 is formed, temporary tracks are laid on both sides of the bottom longitudinal beams 98 on the floor 97, extending longitudinally. A wheel-rail running gear 1 runs along the tracks on the floor 97, allowing the trolley to be moved longitudinally and assembled step by step. A frame 2 is mounted above the wheel-rail running gear 1 and serves as the main framework of the trolley. All trolley components are mounted on the frame 2.

[0050] The side wall mounting device 3 is mounted on the vehicle frame 2. A gantry crane is used to hoist the side wall blocks 91 onto the side wall mounting device 3 from an open-air opening. The side wall mounting device 3 secures the side wall blocks 91 and moves them to their mounting positions for assembly. In this embodiment, the platform side walls comprise multiple side wall blocks 91, which are arranged longitudinally to form the station's side walls. During construction, the trolley travels longitudinally, assembling the side wall blocks 91 one by one.

[0051] The roof panel installation device 5 is mounted on the vehicle frame 2 and is used to support the roof panel and move it to the target location for assembly. A gantry crane hoists the longitudinal beams from an open-air opening onto a trolley, which then travels along tracks to carry the beams to the target location for assembly. During construction, the trolley travels longitudinally, assembling the longitudinal beams one by one.

[0052] The longitudinal beam mounting device 4, mounted on the vehicle frame 2, is used to secure the longitudinal beams and move them to the target location for assembly. A gantry crane hoists the longitudinal beams from an open-air opening onto a trolley, which then travels along tracks to carry the beams to the target location for assembly. During construction, the trolley moves longitudinally, assembling the longitudinal beams one by one.

[0053] Based on the above technical solution, this embodiment provides an implementation of a side wall mounting device 3: like Figure 5 As shown, the side wall installation device 3 includes a side wall support mechanism 31, a side wall installation mechanism 32, and a side wall fine-adjustment mechanism 33. The side wall support mechanism 31 is located below the vehicle frame 2 and extends toward one side of the vehicle frame 2, specifically toward the direction of the side wall to be assembled. A gantry crane hoists the side wall block 91 onto the side wall support mechanism 31, which supports the side wall block 91 from below.

[0054] The side wall mounting mechanism 32 is provided on the top of the vehicle frame 2. When the gantry crane lifts the side wall block 91 onto the side wall supporting mechanism 31, the side wall mounting mechanism 32 is connected to the side wall block 91. The side wall mounting mechanism 32 is used to apply a driving force to the side wall block 91 to move the side wall block 91 for assembly.

[0055] The side wall fine adjustment mechanism 33 is disposed at the lower portion of the vehicle frame 2 and is used to apply a force to the lower portion of the side wall block 91 to finely adjust the pitch angle of the side wall block 91 .

[0056] The above scheme supports the side wall blocks through the side wall supporting mechanism, and the side wall installation mechanism applies a driving force to the side wall blocks to move the side wall blocks for assembly. The side wall fine-adjustment mechanism is used to finely adjust the pitch angle of the side wall blocks, which can ensure the stable installation of the side wall blocks and improve the accuracy, thereby improving the assembly quality.

[0057] Based on the above technical solution, the side wall mounting device 3 further includes a side wall clamping mechanism 34. The side wall clamping mechanism 34 is arranged in the middle of the vehicle frame 2, extending from both sides of the side wall block 91 to the side of the side wall block 91 facing away from the trolley, and applies a clamping force to the side wall block 91 to prevent the side wall block 91 from tipping over during movement.

[0058] This embodiment provides an implementation method in which the side wall mounting device 3 is located on one side of the vehicle frame 2, specifically, near the side wall to be assembled. A side wall block 91 is hoisted onto the side wall mounting device 3 by a gantry crane. The side wall mounting mechanism 32 is then moved laterally, longitudinally, and vertically into position for assembly.

[0059] For the side wall supporting mechanism 31, this embodiment provides a specific example: Figure 7 As shown, the side wall support mechanism 31 includes at least two side wall support beams 311 extending in the transverse direction. The at least two side wall support beams 311 are spaced apart in the longitudinal direction. The side wall blocks 91 are placed on each of the side wall support beams 311, and each of the side wall support beams 311 supports the side wall blocks 91.

[0060] The side wall supporting beam 311 may be a steel beam with a U-shaped cross section, an I-shaped steel beam, or a steel beam of other shapes.

[0061] Furthermore, the upper surface of the side wall supporting beam 311 is flat, and the upper surfaces of the side wall supporting beams 311 are at the same height to adapt to the bottom shape of the side wall block 91 .

[0062] The above scheme of using at least two side wall supporting beams 311 to be spaced apart leaves a gap between two adjacent side wall supporting beams 311 for easy observation and operation. Of course, in addition to the above scheme, supporting plates can also be used to replace the above side wall supporting beams 311.

[0063] For the side wall clamping mechanism 34 , this embodiment provides a specific example: the side wall clamping mechanism includes: at least one pair of claws 341 and at least one claw driver 342 , and one claw driver 342 is connected to one claw 341 for driving the claw 341 to move.

[0064] Specifically, one pair of claws 341, two pairs of claws 341, or three pairs of claws 341 may be used. When a pair of claws 341 is used, the claws 341 are located in the middle of the side wall block 91. When two or three pairs of claws 341 are used, the claws 341 are arranged vertically at intervals. This embodiment uses only one pair of claws 341 as an example.

[0065] The two claws 341 in a pair are spaced apart in the longitudinal direction, have the same height, and have space between them to accommodate the side wall block 91. The inner side of the claws 341 is provided with a groove for the side surface of the side wall block 91 to be embedded.

[0066] One end of the gripper actuator 342 is connected to one gripper 341, and the other end is fixed to the vehicle frame 2. The gripper actuator 342 is used to drive the grippers 341 to swing, moving the two grippers 341 toward or away from each other. When the two grippers 341 approach each other, they grip the side wall block 91 from both sides; when the two grippers 341 move away from each other, they release the side wall block 91. The gripper actuator 342 can be a drive mechanism such as a pneumatic cylinder, a hydraulic cylinder, or a motor.

[0067] This embodiment provides a method for fine-adjusting the side wall 33. The mechanism 33 includes a fine-adjusting connector 331 and a fine-adjusting actuator 332. One end of the fine-adjusting actuator 332 is connected to the vehicle frame 2, and the other end is connected to the fine-adjusting connector 331. The fine-adjusting connector 331 is connected to the side wall block 91. The fine-adjusting actuator 332 is used to drive the fine-adjusting connector 331 to move laterally, acting on the lower portion of the side wall block 91, thereby finely adjusting the pitch angle of the side wall block 91 to meet the requirements of side wall assembly.

[0068] Fine-adjustment actuator 332 can be a pneumatic cylinder, hydraulic cylinder, or other actuator. In this embodiment, a hydraulic cylinder is used as an example. The end of fine-adjustment connector 331 is bolted to sidewall block 91. Two sidewall fine-adjustment mechanisms 33 are spaced apart and work together to fine-tune sidewall block 91, front to back, and left to right. The H-shaped steel at the bottom of sidewall block 91 aligns with the groove in the base plate. Once aligned, sidewall block 91 is lowered into the groove.

[0069] On the basis of the above technical solution, the side wall mounting device 3 further comprises: a side wall mounting frame 35, which is arranged on one side of the vehicle frame 2. The side wall mounting frame 35 is a hollow structure, which is formed by connecting vertical beams, longitudinal beams and transverse beams to form a hollow frame structure.

[0070] The side wall fine adjustment mechanism 33 is located within the interior space of the side wall mounting frame 35. The fine adjustment driver 332 in the side wall fine adjustment mechanism 33 can be fixed to the side wall mounting frame 35 or to the vehicle frame 2. The side wall fine adjustment mechanism 33 extends laterally and can be extended or retracted from the interior space of the side wall mounting frame 35.

[0071] The side wall supporting mechanism 31 is located below the side wall mounting frame 35 and extends out of the side wall mounting frame 35. One side surface of the side wall block 91 is in contact with the side wall mounting frame 35. The side wall holding mechanism 34 is located above the side wall mounting frame 35, and the holding claw 341 extends out of the side wall mounting frame 35 to hold the side wall block 91.

[0072] On the basis of the above technical solution, this embodiment provides an implementation method of a side wall mounting mechanism 32: Figure 8 As shown, the side wall installation mechanism includes: a side wall longitudinal moving frame 321, a side wall lifting frame 322, a side wall transverse moving frame 323, a transverse moving arm 324, a longitudinal moving driver 325, a vertical driver 326 and a transverse moving driver 327.

[0073] The sidewall longitudinal shift frame 321 is mounted on the vehicle frame 2 and extends longitudinally. The sidewall lifting frame 322 is slidably mounted on the sidewall longitudinal shift frame 321 and is movable longitudinally relative to the sidewall longitudinal shift frame 321. A longitudinal shift driver 325 is mounted on the sidewall longitudinal shift frame and connected to the sidewall lifting frame 322 to provide a driving force for longitudinal movement.

[0074] The side wall traverse frame 323 is slidably mounted on the side wall lifting frame 322 and is movable vertically relative to the side wall lifting frame 322. The vertical actuator 326 is mounted on the side wall lifting frame 322 and is connected to the side wall traverse frame 323 to provide vertical driving force to the side wall traverse frame 323.

[0075] The traverse arm 324 is mounted on the sidewall traverse frame 323 and is slidable laterally relative to the sidewall traverse frame 323. A traverse driver 327 is mounted on the sidewall traverse frame 323 and connected to the traverse arm 324, providing lateral driving force to the traverse arm 324. The end of the traverse arm 324 is connected to the sidewall block 91. Through the coordinated action of these components, the sidewall block 91 is driven to move longitudinally, transversely, and vertically.

[0076] The side wall block 91 is placed on the side wall supporting mechanism 31, and the side wall holding mechanism 34 holds the side wall block 91 tightly. The trolley can drive the side wall block 91 to move longitudinally to realize the carrying. After moving into position, the side wall holding mechanism 34 releases the side wall block 91, and the side wall installation mechanism 32 drives the side wall block 91 to move horizontally, longitudinally and vertically to the assembly position for assembly. During this process, the position of the side wall block 91 can be finely adjusted by the side wall fine adjustment mechanism 33 so that the bottom end of the side wall block 91 is aligned with the assembly interface 20 (such as Figure 12 ).

[0077] After the side wall block 91 is installed, an adjustment rod for the ground-connected wall is installed on the top of the side wall block 91 to connect and fix the side wall 91 to the ground. Concrete can be poured between the side wall block 91 and the ground-connected wall.

[0078] Based on the above solution, the side wall lifting frame 322 can specifically include a lifting top plate 3221 and lifting legs 3222 disposed at the bottom of the lifting top plate 3221. There are four lifting legs 3222, with two lifting legs 3222 forming a set. A gap is left between the two sets of lifting legs 3222 to accommodate the side wall longitudinal displacement frame 321. The two sets of lifting legs 3222 are arranged on either side of the side wall longitudinal displacement frame 321. The gap between the lifting legs 3222 and the side wall longitudinal displacement frame 321 is only sufficient for relative sliding movement between the two. This solution improves the stability of the side wall mounting mechanism 32 and prevents it from tipping over.

[0079] The sidewall transverse frame 323 specifically includes a lifting slide beam 3231 and a transverse beam 3232. The lifting slide beam 3231 extends vertically and is telescopically disposed within the interior space of a lifting leg 3222. The transverse beam 3232 is connected to the top of each lifting slide beam 3231 and extends laterally. The transverse arm 324 is telescopically disposed within the interior space of the transverse beam 3232.

[0080] For structures with steel purlins or concrete waist beams on the side walls, the gantry crane cannot directly lift the side wall block 91 vertically downward onto the trolley due to the obstruction of the steel purlins or concrete waist beams. To address this problem, the trolley is further optimized in this embodiment, and the frame 2 can move laterally relative to the wheel-rail running device 1, which can supplement the lateral travel of the side wall block 91.

[0081] Figure 13 In the figure, two assembling trolleys are used to assemble the side wall blocks on both sides of the platform. In this embodiment, the positions of these two trolleys are used to assemble the concrete waist beam. Figure 13 As shown, the frame 2 moves about 1.5 m in the direction away from the side wall, and the side wall block 91 is lifted downwards onto the trolley by the gantry crane (as shown in FIG. Figure 13 The right trolley in the figure) During this process, the side wall block 91 can avoid the concrete waist beam 30. Specifically, the side wall block 91 is placed on the side wall support mechanism 31 and is clamped by the side wall clamping mechanism 34. At this time, the height of the side wall block 91 is lower than the concrete waist beam 30, and the gantry crane is withdrawn. The frame 2 then moves horizontally about 1.5m relative to the wheel-rail running device, close to the side wall (such as Figure 13 The right trolley in the middle continues to move about 1m to the right), and then the side wall blocks 91 are assembled through the side wall installation mechanism 32, which can solve the problem of the concrete waist beam being blocked. The trolley on the left is in the state of completing the splicing of the wall blocks on one side.

[0082] If it is a steel purlin, the frame moves 1 m in the horizontal direction, so that the side wall block 91 can be hoisted away from the steel purlin.

[0083] Based on the above scheme, two trolleys can be used to assemble the side walls on both sides of the bottom longitudinal beam 98 at the same time, which can greatly improve efficiency. After the lower station is spliced, the trolley moves up to splice the upper station.

[0084] Based on the above technical solution, this embodiment further optimizes the trolley for scenarios where steel beams are present. The longitudinal beam installation device 4 is capable of carrying and assembling the middle longitudinal beam 95 and the top longitudinal beam 96. In this embodiment, the longitudinal beams mentioned below are described using the middle longitudinal beam 95 as an example. Those skilled in the art can apply the solution of this embodiment to the splicing of the top longitudinal beam 96.

[0085] like Figures 14 to 16 As shown, the longitudinal beam installation device 4 includes: a mobile platform 41 and a hanging frame 42. The mobile platform 41 is arranged on the top of the vehicle frame 2 and can move laterally relative to the vehicle frame.

[0086] The hoisting frame 42 is installed above the mobile platform 41, with space between the two platforms to accommodate the longitudinal beams. The outer ends of the hoisting frame 42 are equipped with at least two connectors for temporarily connecting the longitudinal beams. At an open-air opening, a gantry crane lifts the longitudinal beam (for example, the center longitudinal beam 95) and moves it to the area between the mobile platform 41 and the hoisting frame 42. The connectors on the hoisting frame 42 are then connected to the center longitudinal beam 95. Once the connection is complete, the gantry crane is removed. A trolley, using a wheel-rail running system, travels along tracks to carry the center longitudinal beam 95.

[0087] When moving to the target position, the mobile platform 41 extends horizontally toward the direction of assembling the middle longitudinal beam 95. After reaching the correct position, the middle longitudinal beam 95 is lowered and overlapped between two adjacent middle columns 92. The connection between the connecting part of the lifting frame 42 and the middle longitudinal beam 95 is removed to complete the assembly of the middle longitudinal beam 95.

[0088] Based on the above technical solution, the longitudinal beam installation device 4 further includes a longitudinal beam support frame 43. The longitudinal beam support frame 43 is arranged above the mobile platform 41 and extends vertically. A space for accommodating the longitudinal beam is left between the top of the longitudinal beam support frame 43 and the connection portion on the hanging frame 42.

[0089] Considering that the trolley travels a long distance, in order to reduce the risks in the lifting and traveling process, the longitudinal beam can be placed on the longitudinal beam support frame 43, and the longitudinal beam is supported by the longitudinal beam support frame 43.

[0090] The longitudinal beam support frame 43 can be formed by multiple rod-shaped mechanisms, which are arranged vertically, horizontally and along the longitudinal beam and connected to each other. It can support the weight of the longitudinal beam and ensure the stability of the longitudinal beam during the travel of the trolley.

[0091] Furthermore, the hanging frame 42 can move laterally relative to the mobile platform 41. When the lateral movement of the mobile platform 41 is limited, the hanging frame 42 can be further moved laterally to increase the movable travel of the longitudinal beam, thereby meeting the assembly requirements of the longitudinal beam.

[0092] The hanging frame 42 can also move vertically relative to the mobile platform 41 to accommodate longitudinal beams of varying thicknesses. For example, a vertical support 44 is vertically mounted on the mobile platform 41 or on the vehicle frame 2, and the hanging frame 42 is mounted on top of the vertical support 44. The hanging frame 42 can move up and down relative to the vertical support 44.

[0093] Regarding the hoisting frame 42, this embodiment provides an implementation method: the hoisting frame 42 includes a hoisting arm 421 and two auxiliary arms 422. The two auxiliary arms 422 are arranged parallel and side by side, extending in the horizontal direction and spaced apart in the longitudinal direction. The hoisting arm 421 is connected between the outer ends of the two auxiliary arms 422. The hoisting arm 421 is provided with a connecting portion 423 for connecting to the longitudinal beam. Specifically, the hoisting arm 421 and the two auxiliary arms 422 are connected to form a rectangular frame with one side open, and the open end is away from the location where the longitudinal beam is to be assembled. The hoisting arm 421 is close to the location where the longitudinal beam is to be assembled.

[0094] Based on the above solution, a sliding guide structure is provided between the auxiliary arm 422 and the top of the mobile platform 41, allowing the auxiliary arm 422 to move laterally relative to the mobile platform 41 via the sliding guide structure. The sliding guide structure can be installed at the top of the vertical support 44 and can be a slider and slide rail, or a slider and slide groove. A driving mechanism such as a hydraulic cylinder is used to provide lateral driving force to the auxiliary arm 422.

[0095] The connection portion 423 on the hoisting frame 42 can be a lifting ring, and at least two lifting rings are spaced apart along the length direction (i.e., longitudinal direction) of the hoisting arm 421 to meet the hoisting requirements of the longitudinal beam. The lifting rings can be connected to the longitudinal beam through ropes.

[0096] Alternatively, the connecting portion 423 may be a hook that is hooked on a ring at the top of the longitudinal beam.

[0097] The above technical solution enables the hoisting of longitudinal beams. During construction, a trolley is first used to assemble the central column 92 in the middle of the station. Multiple central columns 92 are arranged in a longitudinally spaced sequence. The trolley is then used to carry the central longitudinal beam 95 to a position between two adjacent central columns 92. The central longitudinal beam 95 is hoisted using the hoisting frame 42 and moved horizontally between and above the two central columns 92. Once in position, the central longitudinal beam 95 is lowered and connected between the two adjacent central columns 92. A longitudinal tightening force is then applied to the central columns 92 to tighten the central longitudinal beam 95 longitudinally, completing the assembly of the longitudinal beams.

[0098] In the above scheme, all the center columns can be installed before assembling the center longitudinal beams; or one center longitudinal beam can be assembled after each two adjacent center columns are installed.

[0099] On the basis of the above technical solution, the longitudinal beam installation device 4 can also cooperate with the center column 92 to lift, transport and install. Specifically, a structure such as a lifting ring can be set on the top of the center column 92 and connected to the connection part on the lifting frame 42 to realize the lifting of the center column 92.

[0100] Furthermore, the mobile platform 41 is optimized so that the mobile platform 41 can support and fix the center column 92. Figure 9 As shown, the mobile platform 41 includes two parallel and side-by-side movable platforms 411 extending laterally. A space is left between the two movable platforms 411 to accommodate the center column 92. The center column 92 is placed between the two movable platforms 411. The movable platforms 411 are used to temporarily secure and transport the center column 92.

[0101] In one specific embodiment, the cross-sections of the center column 92 and the top of the center column 92 are both rectangular, with the center cross-section length being shorter than the top cross-section length. The distance between the two movable platforms 411 is shorter than the top cross-section length of the center column 92, but longer than the center cross-section length of the center column 92. The center of the center column 92 then enters the gap between the two movable platforms 411 and becomes lodged between them, preventing it from falling downward. Thus, the two movable platforms 411 secure and support the center column 92.

[0102] Furthermore, a locking member 412 is provided at the outer end of the movable platform 411. A locking rod 413, longer than the distance between the two movable platforms, is employed, with its ends removably connected to the locking members 412 on the two movable platforms 411. The locking rod 413 prevents the center column 92 from moving outward, further improving reliability during transport and preventing the center column 92 from falling out of the gap between the two movable platforms 411.

[0103] In addition, a center column support surface can be provided on the upper surface of the end portion of the wheel-rail running device 1 corresponding to the longitudinal beam mounting device 4, and the bottom end of the center column 92 abuts against the center column support surface. The center column support surface can be concave to position the center column 92 and improve its stability.

[0104] On the basis of the above technical solution, this embodiment further provides a method for assembling a center column, using the above center column mounting bracket 6 .

[0105] like Figure 22 and Figure 23As shown, the bottom of the center column mounting frame 6 is provided with running wheels, which can walk on the station floor. The top of the center column mounting frame 6 is provided with an opening that can accommodate the middle part of the center column 92, and the opening size is larger than the middle size of the center column 92 and smaller than the top size of the center column 92.

[0106] At the open-air opening, the gantry crane lifts the center column 92 and enters the center column mounting frame 6 from the opening. Since the top size of the center column 92 is large, it can be stuck on the center column mounting frame 6. The center column mounting frame 6 supports the center column 92 and can walk on the station floor to the installation position for installation.

[0107] In one embodiment, the center column mounting frame 6 includes two detachably connected center column brackets 61. Each center column bracket 61 is equipped with running wheels at its base, allowing each center column bracket 61 to travel on the floor. The center column brackets 61 are steel-frame structures composed of multiple connected steel beams. The tops of the two center column brackets 61 are detachably connected and form an opening.

[0108] During construction, a gantry crane hoists the center column 92 between the two center column brackets 61 at the open-air opening. The two center column brackets 61 are then brought close together and connected to form an opening, and the center column brackets 61 are locked into the opening. The center column mounting frame 6 then travels entirely on the baseplate, with the two center column brackets 61 positioned on either side of the bottom longitudinal beam to align the center column 92 with its installation position on the bottom longitudinal beam. Once the center column 92 is installed, the two center column brackets 61 are separated, each traveling on the baseplate and returning to the open-air opening to await the hoisting of the next center column 92.

[0109] The solution of providing two center column brackets 61 can reduce the difficulty of the center column entering the opening of the center column mounting frame 6, thereby improving efficiency. Moreover, the detachable connection of the two center column brackets 61 can adapt to center columns of different sizes, thereby meeting the needs of different stations and improving applicability.

[0110] A specific implementation method: The distance between the lower parts of the two center column brackets 61 is greater than the width of the bottom longitudinal beam of the station. The two center column brackets 61 can be symmetrically located on both sides of the bottom longitudinal beam, so that the center column is exactly aligned with the installation position, shortening the time for aligning the center column during construction, thereby improving construction efficiency.

[0111] Furthermore, a support platform 62 is provided on top of the center column bracket 61. A space is left between the support platforms 62 of the two center column brackets 61 to accommodate the center portion of the center column. Two center column stopper assemblies 63 are connected between the two support platforms 62. The two center column stopper assemblies 63 are spaced apart and form an opening with the two support platforms 62.

[0112] The center column limit assembly 63 may include a connecting rod and a connecting piece. A vertical connecting plate is provided on the supporting platform 62, and a hole is formed in the connecting plate. The end of the connecting rod is provided with an external thread, which passes through the hole in the connecting plate and is threadedly connected to the connecting piece.

[0113] On the basis of the above technical solution, Figures 17 to 21 As shown, this embodiment also provides an implementation method of a roof installation device 5 , which includes a roof lifting frame 51 , a roof supporting frame 52 and a roof lifting drive mechanism 53 .

[0114] Among them, the top plate lifting frame 51 is set at the top of the frame 2. It can adopt multiple strip beams arranged in the horizontal, longitudinal and vertical directions to connect into a hollow frame structure, which can be welded to the top of the frame 2.

[0115] The roof support bracket 52 is mounted on the top of the roof lift 51 and is movable vertically relative to the roof lift 51. The roof support bracket 52 supports the roof. The roof panels mentioned below are described using the middle roof panel 93 as an example. Those skilled in the art can apply the technical solutions provided in this embodiment to assemble the roof panel 94.

[0116] The top plate lifting drive mechanism 53 is arranged between the top plate lifting frame 51 and the top plate supporting frame 52, and is used to provide a driving force for the vertical movement of the top plate.

[0117] During the construction process, the middle top plate 93 is hoisted onto the top plate support bracket 52 at the open-air opening at one end of the steel temporary beam by a gantry crane. The top plate support bracket 52 then supports the middle top plate 93. The trolley then moves along the track to the installation position. The top plate lifting drive mechanism 53 adjusts the height of the top plate support bracket 52 so that the middle top plate 93 above the top plate support bracket 52 is higher than the side wall blocks 91 and the middle longitudinal beam 95 on both sides. The trolley then continues to move toward the installed middle top plate 93 until it reaches the target position. The top plate lifting drive mechanism 53 is then activated to lower the top plate support bracket 52 and the middle top plate 93 until the ends of the middle top plate 93 overlap the side wall blocks 91 and the middle longitudinal beam 95, completing the assembly of the middle top plate 93.

[0118] Based on the above technical solution, this embodiment provides an implementation of a roof support bracket 52: the roof support bracket 52 includes two roof support beams 521. The two roof support beams 521 are arranged parallel and side by side, respectively, on either side of the roof lifting frame 51. The distance between the two roof support beams 521 is less than the length of the roof. The roof is placed on the two roof support beams 521, with the length of the roof perpendicular to the roof support beams 521.

[0119] Furthermore, the top plate lifting frame 51 can also move laterally relative to the vehicle frame 2 . During the assembly process, the top plate lifting frame 51 moves laterally to adjust the lateral position of the middle top plate 93 .

[0120] Furthermore, by installing an extrusion fixture 54 on the upper surface of the middle portion of the roof support beam 521, the extrusion fixture 54 can move relative to the roof support beam 521. An extrusion driver is installed on the roof support beam 521 and connected to the extrusion fixture 54 to apply a longitudinal driving force to the extrusion fixture 54. During the transport process, the middle roof panel 93 is placed on the extrusion fixture 54. During the assembly process, after the middle roof panel 93 is overlapped with the side wall blocks 91 and the middle longitudinal beam 95, the extrusion driver is activated, driving the extrusion fixture 54 to apply a longitudinal extrusion force to the middle roof panel 93, thereby compacting the newly assembled middle roof panel 93.

[0121] Sealing strips are embedded in the side surfaces of the middle top plates 93. When a longitudinal extrusion force is applied to the middle top plates 93, the sealing strips are tightly pressed between adjacent middle top plates 93, thereby improving the waterproof effect.
