Description

Technical Field

[0001] The invention belongs to the field of building construction, and in particular relates to a method for erecting a large-span steel structure high-altitude passage in the air. Background Art

[0002] As large buildings gradually increase, the number of floors and spans of high-altitude large-span connected structures in reinforced concrete high-rise buildings are increasing. These connected structures are connected to the towers on both sides at the height of the building, and steel structure corridors are set at the height of the air to achieve high-level conversion. The steel structure of the corridor has heavy self-weight, high height, large span, large construction load, high difficulty and danger, and high installation precision requirements.

[0003] Traditional skyways are mostly constructed by vertically hoisting between two buildings. After reaching the predetermined height, they need to remain suspended, and then install a support structure at the entrance of the passage. The support structure and both ends of the skyway are connected and fixed to complete the entire skyway operation. However, this makes the skyway unstable when suspended and prone to lateral deviation, which makes it impossible to accurately install the support structure, thus affecting the quality of the skyway installation. Summary of the invention

[0004] In order to solve the above technical problems, the inventors have obtained the technical solution of the present invention through practice and summary. The present invention adopts the following technical solution:

[0005] A method for erecting a large-span steel structure high-altitude passage in the air, the erection steps are as follows:

[0006] Step 1: Installation of hole support:

[0007] A support module is installed at the opening of the building passage, the support module includes an upper chord and a lower chord, the upper chord is fixed to the upper floor slab by anchor bolts, the lower chord is fixed to the lower floor slab by anchor bolts, a belly diagonal rod is installed between the upper chord and the lower chord, the length of one end of the support module exposed to the building passage opening is 30-50cm, and the end of the exposed end is provided with a support body arranged obliquely downward;

[0008] Step 2: Hanger assembly

[0009] A lifting rope and a hanger are passed through the bottom of the lifting equipment, and a driving wheel assembly is installed on the hanger. There are four driving wheel assemblies, two in a group, and two groups are distributed front and back. The four driving wheel assemblies are respectively located at both ends of the hanger near the side position, and the two driving wheel assemblies located on the same side of the hanger drive a wire rope together;

[0010] Each driving wheel assembly includes a driving wheel, a clamping wheel, and a driving motor. The driving motor is installed on the hanger and is used to drive the driving wheel to rotate. The clamping wheel is located on the top of the driving wheel and is used to clamp the steel wire rope between the two. Both ends of the steel wire rope are connected to a connecting frame, which is used to connect to the top of the aerial channel.

[0011] Step 3: Middle section module assembly

[0014] Step 4: Assemble the aerial channel

[0015] The hoisting equipment drives the hanger upward through the hoisting rope and the hook, and moves the middle section module and the assembly module upward together. After they move up to half the height, the driving motor drives the respective driving wheels to rotate, and all the driving wheels rotate in the same direction. The driving wheels and the clamping wheels adjust the distance between the two ends of the wire rope and the hanger to complete the tilt adjustment of the middle section module until the projection of the assembly module on the ground is located in the area between the projections of the two support modules on the ground.

[0016] The hanger continues to move upward until the height of the assembly module at the bottom is greater than the height of the supporting module;

[0017] The driving motor drives the respective driving wheels to rotate in opposite directions, and all the driving wheels rotate in the same direction. The driving wheels and the clamping wheels adjust the distance between the two ends of the wire rope and the hanger in opposite directions to complete the horizontal adjustment of the middle section module.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. The support module is installed in the reserved channel opening first, and then the middle section module is installed. When installing the middle section module, the posture is adjusted in the air to complete the upward movement, and it passes through the two support modules smoothly. After passing through, it is adjusted to a horizontal posture in the air, and then placed between the two support modules through vertical downward movement. The support module and the middle section module are paired to achieve precise installation, which is used to solve the problem that the existing vertical lifting technology cannot effectively achieve aerial assembly. At the same time, an auxiliary traction component is set on the ground to assist the hanger to always be in a stable state. Secondly, it ensures that the middle section module prevents the problem of swaying during the upward process, which can ensure the precise construction of the middle section module through the assembly module and the support module.

[0041] 2. In the past, most steel structures were assembled with high-strength bolts. However, bolts are connected in a shearing force, which is prone to fatigue and leads to poor durability of the structural connection. Therefore, in the assembly method, a lifting block is inserted into the positioning groove to achieve a mortise and tenon connection. At the same time, the lifting block can be lifted and adjusted by adjusting the screw rod, and the shear damage (poor shear resistance) caused by the relative displacement trend between the assembly module and the support module is converted into a pulling damage in the screw rod (strong tensile resistance), thereby improving the durability of the structure. Secondly, a one-way feeding method is adopted for the drive block, so that it can be fed in one direction. Through the joint action of the screw rod and the elastic locking body, the durability is further improved and the problem of thread fatigue is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0057] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0058] Embodiment 1, as Figures 1 to 4 As shown, a method for erecting a large-span steel structure high-altitude passage in the air, the erection steps are as follows:

[0059] Step 1: Installation of hole support:

[0060] A support module 10 is installed at the opening of the building passage. The support module 10 includes an upper chord 11 and a lower chord 12. The upper chord 11 is fixed to the upper floor slab by anchor bolts, and the lower chord 12 is fixed to the lower floor slab by anchor bolts. A diagonal rod 13 is installed between the upper chord 11 and the lower chord 12. The length of one end of the support module 10 exposed to the building passage opening is 30-50 cm, and the end of the exposed end is provided with a support body 14 arranged obliquely downward;

[0061] Step 2: Assemble the hanger 20

[0062] like Fig.11 As shown, at the bottom of the lifting equipment, a lifting rope 15 and a hanger 20 are passed through, and a driving wheel assembly is installed on the hanger 20. There are four driving wheel assemblies, which are arranged in groups of two, and the two groups are distributed front and back. The four driving wheel assemblies are respectively located at both ends of the hanger 20 near the side positions, and the two driving wheel assemblies located on the same side of the hanger 20 jointly drive a steel wire rope 21;

[0063] Each driving wheel assembly includes a driving wheel 22, a clamping wheel 23, and a driving motor 24. The driving motor 24 is mounted on the hanger 20 and is used to drive the driving wheel 22 to rotate. The clamping wheel 23 is located on the top of the driving wheel 22 and is used to clamp the steel wire rope 21 between the two. Both ends of the steel wire rope 21 are connected to a connecting frame 25, and the connecting frame 25 is used to be connected to the top of the aerial channel.

[0064] Step 3: Assemble the middle module 30

[0065] The middle section module 30 is assembled on the ground through a tire frame, and assembly modules 40 are provided at both ends, and the assembly modules 40 correspond to the support modules 10 in position;

[0066] Install the connecting frame 25 on the top of the middle section module 30;

[0067] Step 4: Assemble the aerial channel

[0068] The hoisting equipment drives the hanger 20 upward through the hoisting rope 15 and the hook, and moves the middle section module 30 and the assembly module 40 upward together. After ascending to half the height, the driving motor 24 drives the respective driving wheels 22 to rotate, and all the driving wheels 22 rotate in the same direction. The driving wheels 22 and the clamping wheels 23 adjust the distance between the two ends of the wire rope 21 and the hanger 20 to complete the tilt adjustment of the middle section module 30, until the projection of the assembly module 40 on the ground is located in the area between the projections of the two support modules 10 on the ground;

[0069] The hanger 20 continues to move upward until the height of the assembly module 40 at the bottom is greater than the height of the support module 10;

[0070] The driving motor 24 drives the respective driving wheels 22 to rotate in the opposite direction, and all the driving wheels 22 rotate in the same direction. The driving wheels 22 and the clamping wheels 23 adjust the distance between the two ends of the wire rope 21 and the hanger 20 in the opposite direction, completing the horizontal adjustment of the middle section module 30;

[0071] After the horizontal adjustment is completed, the hanger 20 moves downward, and the middle section module 30 and the assembly module 40 are vertically and smoothly lowered between the two support modules 10, and the aerial passage is obtained by assembling the assembly module 40 and the support module 10.

[0072] In this embodiment, the driving motor 24 drives the driving wheel 22 to rotate, thereby driving the wire rope 21 to move, adjust the distance between the connecting frame 25 and the hanger 20, and then stably adjust the inclination angle of the middle section module 30. The installation position of the connecting frame 25 is symmetrically distributed on both sides of the center of gravity of the middle section module 30 to ensure smooth operation during the adjustment process. The angle inclination adjustment is used to ensure smooth passage through the area between the two support modules 10. When falling, an aerial passage can be obtained by pairing the assembly module 40 and the support module 10.

[0073] Embodiment 2, as Figures 1 to 7 As shown, the following improvements are made on the basis of the above embodiment:

[0074] Since it is an aerial operation, only the top hoisting method is often used, which will cause shaking during the aerial assembly process. Therefore, an auxiliary assembly part is added, that is: a traction component is installed on the ground, and the traction component includes a traction rope 51 and a traction electric drum 52. One end of the traction rope 51 is wound around the traction electric drum 52, and the other end is installed on the middle section module 30. The speed of the traction electric drum 52 to retract and release the traction rope 51 is adaptively adjusted according to the change in the position of the traction rope 51 installation point on the middle section module 30 relative to the traction electric drum 52. The traction rope 51 and the lifting rope 15 pull the middle section module 30 to both sides so that the middle section module 30 always remains in a stable state.

[0075] Three arc-shaped steel belts 53 are arranged on the outside of the traction rope 51. The three arc-shaped steel belts 53 are wrapped around the outside of the traction rope 51. A female head 532 is arranged on one side of the three arc-shaped steel belts 53, and a male head 531 is arranged on the other side. The sides of two adjacent arc-shaped steel belts 53 are connected and matched through the female head 532 and the male head 531.

[0076] A storage box 54 is arranged on the periphery of the traction electric drum 52 , a spiral track groove 541 is arranged in the storage box 54 , one end of the arc-shaped steel belt 53 is connected to the end of the traction rope 51 , and a slider 542 is installed at the other end, and the slider 542 is installed in the spiral track groove 541 .

[0077] The traction electric roller 52 and the storage box 54 are installed on the frame 50, and the frame 50 is provided with a receiving opening 55, and a rolling roller 56 for adapting and separating the three arc-shaped steel belts 53 is installed at the receiving opening 55, and a groove for squeezing the male head 531 out of the female head 532 is provided on the rolling roller 56;

[0078] When extended outward, the rolling roller 56 adapts the male head 531 and the female head 532 of the three arc-shaped steel belts 53 to each other and surrounds them on the outside of the traction rope 51 to form a rigid structure. The three arc-shaped steel belts 53 still maintain a vertical posture when the male head 531 is separated from the groove for the first time, so the three arc-shaped steel belts 53 will maintain rigidity on the outside of the traction rope 51; when retracted, the rolling roller 56 separates the male head 531 and the female head 532 of the three arc-shaped steel belts 53 from each other and puts them into their respective storage boxes 54. The three arc-shaped steel belts are pulled by the belt traction electric roller 52 when the male head 531 is separated from the groove, and the male head 531 will be separated from the female head 532, thereby achieving separation.

[0079] The movable guide rail 57 is installed on the ground, and a walking mechanism is arranged at the bottom of the frame 50. The walking mechanism moves freely on the movable guide rail 57, and the movable guide rail 57 is arranged along the length direction of the middle section module 30. Since there is an angle adjustment operation during the upward process, the movable guide rail 57 and the walking mechanism are arranged at the bottom to achieve relative position adjustment to meet the position change change and ensure the stable posture of the middle section module 30. Due to the auxiliary operation structure assembled by the traction rope 51 and the outer rigid structure, the center of gravity position of the middle section module 30 can be ensured to be accurate, thereby ensuring the accurate assembly of the support module 10 and the assembly module 40, and ensuring the safe construction of the assembly operation of the support module 10 and the assembly module 40.

[0080] Embodiment 3, as Figures 1 to 10 As shown, the following improvements are made on the basis of the above embodiment:

[0081] Since most traditional connections are made with high-strength bolts, the bolts are bound to be subjected to large shear forces. Since the shear resistance of the bolts is much lower than their tensile resistance, they are bound to have poor durability. Therefore, an upwardly inclined assembly body 41 is provided at the end of the assembly module 40, and a positioning groove 42 is provided on the lower surface of the assembly body 41, and a lifting component for matching with the positioning groove 42 is installed on the support body 14.

[0082] The jacking assembly includes a screw rod 15 rotatably mounted on the support module 10 (lower chord 12), a driving block 16 is mounted on the end of the screw rod 15, and a jacking block 17 is arranged on the top of the driving block 16 and slides vertically relative to the support body 14. The jacking block 17 is driven to move vertically by adjusting the screw rod 15 through the driving block 16.

[0083] A one-way feed tooth 18 is provided at the bottom of the support module 10, and a horizontal guide groove 161 and a vertical guide groove 162 are provided inside the driving block 16. A moving block 163 that rotates with the end of the screw 15 is installed in the horizontal guide groove 161, and a guide pin 164 is installed on the moving block 163. A locking block 165 is installed in the vertical guide groove 162. The locking block 165 is provided with a lifting groove 167 that is obliquely downward, and the guide pin 164 is slidably fitted in the lifting groove 167. An elastic locking body that is adapted to the one-way feed tooth 18 is provided at the bottom of the locking block 165.

[0084] The elastic locking body includes a mounting groove installed at the bottom of the locking block 165 through a spring, a sliding body 168 is arranged in the mounting groove, the bottom of the sliding body 168 is exposed on the outside of the mounting groove, and a one-way ratchet is arranged at the bottom of the sliding body 168. The one-way ratchet and the one-way feed tooth are adapted to prevent the driving block 16 from retreating and prevent the lifting block 17 from falling.

[0085] The moving block 163 is driven by the feeding of the screw rod 15 to move horizontally along the horizontal guide groove 161, and then the locking block is moved downward through the guide pin 164 and the lifting groove 167. When the moving block 163 and the driving block 16 are relatively stationary, the two move together. During this period, the sliding body 168 at the bottom of the elastic locking body will be adapted through the one-way ratchet and the one-way feed teeth to prevent the driving block 16 from retreating. The driving block 16 pushes the lifting block 17 upward and enters the positioning groove 42 to realize the socket assembly fit, thereby ensuring the durability, structural strength and safety of the structure.

[0086] Embodiment 4, as Figures 1 to 14 As shown, the following improvements are made on the basis of the above embodiment:

[0087] A U-shaped member 301 is installed on the top of the middle section module 30, and a first arc groove 251 and a second arc groove 252 are provided on the upper side of the connecting frame 25. A first flip member 253 is matched in the first arc groove 251, and a second flip member 254 is matched in the second arc groove 252. The first flip member 253 is located at the top of the second flip member 254 and one end is hinged to the second flip member 254, and a torsion spring is installed at the hinge point. One end of the first flip member 253 away from the second flip member 254 is matched with the first arc groove 251, and one end of the second flip member 254 away from the first flip member 253 is matched with the second arc groove 252. Guide grooves are provided on the side walls of the first arc groove 251 and the second arc groove 252, and a guide body is matched in the guide groove, and the guide body is installed on the side of the corresponding flip member.

[0088] When in use, the outer bottom of the second flip member 254 is set obliquely upward along the side close to the side of the connecting frame 25. The second flip member 254 is flipped downward, or the gravity of the entire connecting frame 25 is used to force the second flip member 254 to flip outward to open the space between the first flip member 253. After the U-shaped member 301 enters, the second flip member 254 is reset under the action of the torsion spring and enters the second arc groove 252 to form an enclosed hooking area. The inner bottom of the second flip member 254 is set obliquely downward along the side close to the side of the connecting frame 25. After assembly, the connecting frame 25 moves downward relative to the air channel, the first flip member 253 is forced to flip outward, the top of the hooking area is opened, and the U-shaped member 301 is separated from the hooking area. After separation, the first flip member 253 is reset under the action of the torsion spring and re-enters the first arc groove 251. The top of the first flip member 253 is set obliquely downward along the side away from the connecting frame 25.

[0089] In summary, the above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. The replacement may be a replacement of a part of the structure, device, method step, or a complete technical solution. Any equivalent replacement or change according to the technical solution and the inventive concept of the present invention shall be covered within the protection scope of the present invention.
