Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a cantilevered corridor combination splicing structure. Background Technology

[0002] Currently, in the construction field, the construction of cantilevered corridors is a common structural component. Traditional construction methods typically involve erecting full-span scaffolding or pre-assembling components and then lifting them as a whole. However, both methods have limitations. First, full-span scaffolding occupies a large amount of space, which restricts other activity areas on the construction site, increases construction time, and is inconvenient for material transportation and personnel movement. Second, in the construction of cantilevered corridors in high-rise twin towers, due to the considerable height, full-span scaffolding is not only complex to erect but also hinders safe passage and working space for construction workers.

[0003] Pre-assembling the components and then lifting them as a whole also presents problems. In the context of high-rise twin towers, these components are often quite heavy, making them difficult to lift using simple mechanical methods. A single crane is insufficient, and coordinating multiple cranes simultaneously is inconvenient, easily leading to angular deviations during lifting and affecting construction efficiency. Furthermore, due to the combined factors of the component's weight and height, the safety of this process is difficult to guarantee, especially since potential accidents during the operation could have serious consequences.

[0004] Therefore, it is necessary to provide a high-rise twin-tower cantilevered corridor combination splicing structure that can effectively improve construction efficiency, reduce construction time and space occupation, and ensure safety and convenience. Utility Model Content

[0005] This utility model proposes a cantilevered corridor combination splicing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cantilevered corridor assembly structure includes two symmetrically spliced ​​corridor frames. Each corridor frame includes an upper chord and a lower chord with identical structure and orientation. The bottom sides of the upper chord are symmetrically provided with uprights and chord members one. The top sides of the lower chord are symmetrically provided with web members and chord members two. The top of the lower chord is provided perpendicular to the upright, and the middle of the web member is provided relative to the chord member. Connecting columns are provided on both sides of the lower end of the upright and on both sides of the lower oblique end of chord member one. The connecting columns are connected to the corresponding pressing spring locking structures.

[0008] Preferably, the push-type spring locking structure includes two lock bodies arranged opposite each other. The top of each lock body has a pressure groove that matches the shape of the connecting post. Two symmetrical locking slots are provided on opposite sides of each pressure groove. Each of the two locking slots contains a first locking block and a second locking block. A spring is provided at one end of each first locking block and the second locking block facing into its respective locking slot. The length of the first locking block and the second locking block is shorter than the depth of the locking slot, and the combined length of the first locking block and the second locking block after contact is longer than the width of the pressure groove.

[0009] Preferably, the pressure groove is provided with a U-shaped pressing block, and the bottom surface of the pressing block is provided with a second spring. The pressing block moves up and down in the pressure groove by the second spring. The upward extension ends on the left and right sides of the pressing block are baffles, and each baffle contacts and blocks the corresponding locking block one or locking block two on the opposite side. When the second spring is not compressed, the baffles on both sides of the pressing block block block the opening of the locking groove to prevent locking block one and locking block two from popping out. After the second spring block block is compressed, the height of the baffles on both sides of the pressing block block block is lower than the height of the locking groove, allowing locking block one and locking block two to pop out.

[0010] Preferably, the end of the first locking block facing the second locking block is provided with a rod, and the end of the second locking block facing the rod is provided with a slot. The rod is inserted into the slot. Limiting blocks are provided on both the upper and lower sides of the first locking block and the upper and lower sides of the second locking block near the first spring. Each locking groove has a limiting groove corresponding to the limiting block. The insertion of the rod into the slot improves the stability of the connection between the first and second locking blocks, and the sliding connection of the limiting blocks within the limiting grooves prevents either the first or second locking block from falling out of the locking groove.

[0011] Preferably, the upper and lower chord plates have identical structures, each including a first crossbeam. Each end of the first crossbeam is connected to a second crossbeam, and a cross-connecting reinforcing steel beam connects the two second crossbeams. Several reinforcing crossbeams are provided on the reinforcing steel beams and between the reinforcing steel beams and the second crossbeams. The reinforcing steel beams and reinforcing crossbeams improve the structural strength of the first and second crossbeams, and scaffolding can be directly erected on the reinforcing steel beams and reinforcing crossbeams.

[0012] Preferably, the upper end of the upright is fixed to both ends of the bottom surface of the first crossbeam of the upper chord, the lower end of the web member is fixed to the top of the second crossbeam of the lower chord, and the lock body is fixed to the left and right sides of the middle of the web member and the top surfaces of both ends of the first crossbeam of the lower chord.

[0013] Preferably, the top of the first and second crossbeams are provided with several lifting lugs, and each of the second crossbeams has an embedded plate at the end opposite to the first crossbeam, the end of the web member opposite to the upright, and the end of the second chord member opposite to the web member. The lifting lugs are used to lift the entire upper or lower chord piece by means of a lifting device. The embedded plates are used for connection and fixation to the external building structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention divides the pergola structure into two components, an upper chord and a lower chord, and employs a separate hoisting construction method. The upper and lower chords are first hoisted to their designed positions between the two high-rise towers, and then assembled. This significantly reduces the load requirements on the hoisting equipment, facilitates the coordination of the working angles of multiple hoisting devices, and avoids the need for traditional full-span scaffolding. This not only effectively shortens the construction period but also solves the problems of material transportation and personnel access difficulties caused by the excessive space occupied by full-span scaffolding. The upper and lower chords are positioned and connected using connecting columns and a press-type spring locking structure, achieving rapid and precise docking between the high-altitude towers. This reduces manual operation and assembly time while improving construction safety.

[0016] This utility model adopts a separate hoisting design for the upper and lower chord plates, reducing hoisting load and simplifying high-altitude assembly. Quick connection is achieved through connecting columns and a press-type spring locking structure, reducing scaffolding erection and improving construction efficiency and safety.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-5 A cantilevered corridor assembly structure includes two symmetrically spliced ​​corridor frames 1. Each corridor frame 1 includes an upper chord 21 and a lower chord 22 with identical structure and orientation. The bottom sides of the upper chord 21 are symmetrically provided with uprights 31 and chord 1 32. The top sides of the lower chord 22 are symmetrically provided with web members 33 and chord 222. The top of the lower chord 22 is perpendicular to the uprights 31, and the middle of the web members 33 is provided relative to chord 1 32. The lower ends of the uprights 31 and the lower diagonal ends of the chord 1 32 are provided with connecting columns 6. The connecting columns 6 are connected to the corresponding pressing spring locking structures 4.

[0025] The push-button spring locking structure 4 includes two lock bodies 41 arranged opposite each other. Each lock body 41 has a pressure groove 411 at its top that matches the shape of the connecting post 6. Two symmetrical locking slots 49 are located on opposite sides of each pressure groove 411. Each locking slot 49 contains a locking block 42 and a locking block 43. A spring 44 is provided at one end of each locking block 42 and locking block 43 facing into its respective locking slot 49. The length of locking block 42 and locking block 43 is shorter than the depth of the locking slot 49, and the combined length of locking block 42 and locking block 43 after contact is longer than the width of the pressure groove 411. The connecting post 6 is a semi-cylinder with a flat top. The curved surface faces the pressure groove 411 for easy positioning and insertion into the pressure groove 411, and the flat top prevents the connecting post 6 from rotating within the pressure groove 411.

[0026] A U-shaped pressing block 47 is provided within the pressing groove 411. A second spring 48 is provided on the lower surface of the pressing block 47. The pressing block 47 moves up and down within the pressing groove 411 via the second spring 48. The upward-extending ends on both sides of the pressing block 47 are baffles 471, each baffle 471 contacting and blocking a corresponding locking block 42 or locking block 43 on its side. When the second spring 48 is not compressed, the baffles on both sides of the pressing block 47 block the opening of the locking groove 49, preventing the first locking block 42 and the second locking block 43 from popping out. After the second spring 48 is compressed, the height of the baffles on both sides of the pressing block 47 is lower than the height of the locking groove 49, allowing the first locking block 42 and the second locking block 43 to pop out.

[0027] The locking block 42 has a rod 421 at its end facing the locking block 43, and a slot 431 at its end facing the rod 421. The rod 421 is inserted into the slot 431. Limiting blocks 46 are provided on the upper and lower sides of the locking block 42 near the spring 44, and on the upper and lower sides of the locking block 43 near the spring 44. Each locking groove 49 has a limiting groove 45 corresponding to each limiting block 46. The insertion of the rod 421 into the slot 431 improves the stability of the connection between the locking block 42 and the locking block 43. The sliding connection of the limiting blocks 46 within the limiting grooves 45 prevents either the locking block 42 or the locking block 43 from falling out of the locking grooves 49.

[0028] The upper chord plate 21 and the lower chord plate 22 have the same structure. Both the upper chord plate 21 and the lower chord plate 22 include a first crossbeam 23. Both ends of the first crossbeam 23 are connected to second crossbeams 24. A cross-connecting reinforcing steel beam 25 is connected between the two second crossbeams 24. Several reinforcing crossbeams 26 are provided on the reinforcing steel beams 25 and between the reinforcing steel beams 25 and the second crossbeams 24. The reinforcing steel beams 25 and the reinforcing crossbeams 26 improve the structural strength of the first crossbeam 23 and the second crossbeams 24, and scaffolding can be directly erected on the reinforcing steel beams 25 and the reinforcing crossbeams 26.

[0029] The upper end of the upright 31 is fixed to both ends of the bottom surface of the crossbeam 23 of the upper chord 21, the lower end of the web 33 is fixed to the top of the crossbeam 24 of the lower chord 22, and the lock body 41 is fixed to the left and right sides of the middle part of the web 33 and the top surfaces of both ends of the crossbeam 23 of the lower chord 22.

[0030] The tops of the first crossbeam 23 and the second crossbeam 24 are equipped with several lifting lugs. Each of the second crossbeams 24, opposite to the first crossbeam 23, the web member 33, opposite to the upright 31, and the chord member 222, opposite to the web member 33, has an embedded plate 5. The lifting lugs are used to lift the entire upper chord 21 or lower chord 22 using a lifting device. The embedded plates 5 are used for connection and fixation to the external building structure.

[0031] When using this utility model, the upper chord plate 21 and the lower chord plate 22 are assembled on the ground. The upright 31 and the first chord 32 are welded and fixed to the upper chord plate 21, and the web member 33 and the second chord 222 are fixed to the lower chord plate 22. The "horizontal method" is used for hoisting. The upper chord plate 21 and the lower chord plate 22 are lifted to 300mm above the ground for the first hoisting. At this time, the levelness of the upper chord plate 21 and the lower chord plate 22 is checked to see if they are straight. If they are not straight, they must be readjusted and hoisted again. If they are straight, they are lifted another 300mm and the levelness is checked again. If they are straight, they are lifted to the construction position. Then, adjust the positions of the upper chord plate 21 and the lower chord plate 22 as a whole, so that the upright rod 31 corresponds to the pressing spring locking structure 4 on the crossbeam 23 of the lower chord plate 22, and the chord rod 32 of the upper chord plate 21 corresponds to the pressing spring locking structure 4 on the web rod 33. The connecting post 6 on the chord rod 32 or the upright rod 31 is pressed into the groove 411 on the same side of the lock body 41. The connecting post 6 contacts the pressing block 47 and compresses the second spring 48, causing the pressing block 47 to move down in the groove 411. When the stop block is completely moved to the bottom of the groove of the lock slot 49, the spring 44 releases its elastic force to pop out the lock block 42 and the lock block 43. The lock block 42 and the lock block 43 are inserted into each other to fix the connecting column 6 in the pressure groove 411. Then, the workers weld the connection between the upright 31 and the crossbeam 23 of the lower chord 22, between the web member 33 and the chord member 32, and between each embedded plate 5 and the external structure. After cooling for 60 minutes after welding, the cantilevered corridor can be detached from the lifting lug to complete the combined connection.

[0032] This utility model adopts a separate hoisting design for the upper chord plate 21 and the lower chord plate 22, which reduces the hoisting load and simplifies high-altitude assembly. Quick connection is achieved through the connecting column 6 and the press-type spring locking structure 4, reducing scaffolding erection and improving construction efficiency and safety.
