Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to an aerial corridor construction platform. BACKGROUND

[0002] In high-rise building projects, the construction of large-span, large-cantilever concrete aerial corridors faces many technical problems. Taking a high-rise residential project as an example, a 5-meter-high concrete aerial corridor needs to be built at the 28th floor (95 meters high from the ground) between two super high-rise residential buildings. The construction scene has the following outstanding technical problems: first, traditional steel structure corridor construction methods such as overall lifting or aerial scattered assembly process cannot meet the construction requirements of concrete structures; second, the height of the corridor far exceeds the applicable height range of the conventional landing formwork support frame (usually only applicable to heights below 50 meters); third, the specific corridor design has a large cantilever structure, such as a cantilever length of 5-7 meters on the north and south sides, which has exceeded the bearing limit of the conventional I-beam cantilever support system (usually only applicable to cantilevers within 4 meters). The root cause of these technical problems lies in the essential differences between the self-weight characteristics of concrete structures and steel structures, the higher stability requirements of the support system in high-altitude operation environment, and the significant increase in bending moment effect of large cantilever structures. Existing construction techniques are difficult to meet the multiple technical requirements of high-altitude operation safety, large-span support reliability, and concrete pouring process requirements.

Detailed Implementation

[0032] The technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0033] As shown in Figures 1 to 13 The preferred embodiment of the present application proposes an air corridor construction platform arranged between two independent main body structures 10 spaced left and right, and divided into a cantilever area A located at the front side and the rear side of the two main body structures 10 and a gable area B located between the opposite wall sides of the two main body structures 10 according to the platform design area.

[0034] The aerial corridor construction platform comprises a cantilever area support foundation, a gable area support foundation 30, a Bailey frame 40, a profile steel 50 and a patterned steel plate 60. The cantilever area support foundation comprises two symmetrical steel platform supports 20 arranged on two main structures 10, the steel platform support 20 comprising a steel beam 21, a first steel diagonal brace 22 and a second steel diagonal brace 23, the steel beam 21 being arranged in a floor of the main structure 10 and having two ends respectively extending from front and back sides of the main structure 10 to form a cantilever beam structure; the upper end of the first steel diagonal brace 22 is fixedly connected with the bottom of the front end of the steel beam 21, and the lower end of the first steel diagonal brace 22 is fixedly connected with a front side outer wall column 11 (such as a south side outer wall column) of a floor below the main structure 10; the upper end of the second steel diagonal brace 23 is fixedly connected with the bottom of the rear end of the steel beam 21, and the lower end is fixedly connected with a rear side outer wall column 12 (such as a north side outer wall column) of a floor below the main structure 10; the steel beam 21 is suspended on the same floor slab under the support of the first steel diagonal brace 22 and the second steel diagonal brace 23; the front and rear ends of the steel beam 21 are respectively provided with a raised support 24. The gable area support foundation 30 comprises a steel corbel 31 fixedly arranged on opposite wall side outer wall columns 13 (such as east side outer wall columns of one main structure and west side outer wall columns of the other main structure) of the two main structures 10 and a reverse ridge 32 cast on a structural beam of the opposite wall side of the two main structures 10; the top surface of the steel corbel 31, the top surface of the reverse ridge 32 and the top surface of the raised support 24 are flush. A plurality of Bailey frames 40 extend along the left and right directions of the platform and are arranged along the front and back directions of the platform, wherein the Bailey frames 40 located in the cantilever area A are arranged on the raised supports 24, and the two ends thereof respectively extend into the adjacent main structures 10, the two ends of the Bailey frames 40 located in the gable area B are arranged on the steel corbel 31, and the two ends of the other Bailey frames 40 located in the gable area B are arranged on the reverse ridge 32. A plurality of profile steels 50 extend along the front and back directions of the platform and are arranged at intervals along the left and right directions of the platform and are arranged on the top surface of the Bailey frame 40. The patterned steel plate 60 is arranged on the profile steel 50.

[0035] It can be understood that the steel beam 21 refers to the main component bearing the cantilever load, which can be implemented by a box-shaped steel, and its length can be adjusted according to the span in the front and rear directions of the corridor. The first steel inclined support 22 refers to the front side inclined support component, which can be implemented by a welded square steel, and the inclination angle can be controlled within the range of 30-60 degrees to optimize the stress. The second steel inclined support 23 refers to the rear side balance support component, which can be implemented by a welded square steel, and the inclination angle can be controlled within the range of 30-60 degrees to optimize the stress, and together with the first steel inclined support 22, it forms a two-way stable triangular support system. The raised support 24 refers to the elevation adjusting device arranged at the end of the steel beam 21, which can be implemented by a steel structure with a ribbed plate. The steel corbel 31 refers to the bearing component fixed to the relative wall side outer wall column 13, which can be implemented by a box-shaped structure with top plate, bottom plate and vertical plate welded. The counter ridge 32 refers to the concrete reinforcing body poured on the structure beam, which can be formed as a whole by embedding steel bars with the structure beam. The bailey frame 40 refers to the modular steel truss system, which constitutes the main beam of the platform, and can be assembled into a continuous support beam by standard bailey pieces. The profiled steel plate 60 refers to the steel plate laid on the parallelly arranged profiled steel 50 and has protruding patterns on the surface, which constitutes the pavement plate or walkway plate of the platform, and the protruding patterns can be diamond-shaped, flat bean-shaped, round bean-shaped or combined patterns, which mainly play the role of anti-skid.

[0036] Specifically, when the steel beam 21 is arranged on the floor of the main structure 10, the front and rear cantilever ends are rigidly connected with the lower outer wall column through the steel inclined support, effectively dispersing the cantilever bending moment. The elevation control of the steel corbel 31 and the counter ridge 32 makes the bailey frame 40 in the gable area form a continuous support surface, which together with the bailey frame 40 in the cantilever area constitutes the overall platform base. The profiled steel 50 is arranged transversely to form a secondary bearing layer, and the profiled steel plate 60 is used as the working surface layer to realize uniform load distribution. During construction, the embedded installation of the steel platform support 20 is synchronized with the construction of the main structure 10, and the multiple bailey frames 40 are installed on the raised supports 24, steel corbels 31 and reinforced counter ridges 32 with the same elevation by using the whole lifting method.

[0037] Therefore, the embodiment of the present application processes the stress characteristics of the cantilever area A and the gable area B respectively by the partition support design, which adapts to the mechanical requirements of different areas. The combination of the steel beam 21, the steel inclined support and the embedded parts (such as embedded steel plate and steel support column) significantly improves the stability of the high-altitude structure. The bailey frame 40 system realizes the rapid construction of large-span structures, and the composite arrangement of the bailey frame 40 and the profiled steel 50 forms a spatial grid structure with better bending stiffness and bearing redundancy. The platform system not only ensures the stability of the structure, but also realizes the standard modular application of construction materials, providing reliable technical support for the construction of high-altitude concrete corridors, thereby effectively solving the support problem of high-altitude concrete corridor construction.

[0038] Exemplarily, the steel beam 21 is composed of multiple sections of box-shaped steel; the front and rear ends of the steel beam 21 are respectively provided with multiple first vertical rib plates 211 arranged along the length direction of the steel beam 21; of the multiple first vertical rib plates 211, at least two first vertical rib plates 211 are arranged in the connecting region of the steel beam 21 and the first steel diagonal brace 22, and at least two first vertical rib plates 211 are arranged in the connecting region of the steel beam 21 and the second steel diagonal brace 23; the raised support 24 is provided with multiple second vertical rib plates 241 arranged along the length direction of the raised support 24; the number of the second vertical rib plates 241 is greater than the number of the first vertical rib plates 211; of the multiple second vertical rib plates 241, the positions of some second vertical rib plates 241 correspond to the positions of the first vertical rib plates 211 one by one.

[0039] It can be understood that the steel beam 21 is composed of multiple sections of box-shaped steel, which can realize modular hoisting in the high-altitude working environment. The first vertical rib plates 211 are densely arranged in the steel diagonal brace connecting region, which effectively prevents the web plate of the steel beam 21 from local buckling under the action of load force. The number of the second vertical rib plates 241 of the raised support 24 is increased by about 50% compared with the number of the rib plates of the steel beam 21, and through the position correspondence relationship with the rib plates of the steel beam, a continuous force transmission path is formed to uniformly transmit the load of the Bailey truss 40 to the steel beam 21. Through the above technical scheme, the stress concentration problem of the key node of the high-altitude large-span construction platform is effectively solved, the difficulty of high-altitude hoisting is reduced through the sectional structure, the stiffness of the connecting node is enhanced by using the multi-stage rib plate system, and the structural safety of the construction platform when bearing the concrete pouring load at 95 meters high is ensured.

[0040] Exemplarily, the first steel diagonal brace 22 and the second steel diagonal brace 23 are both square steel; the overhanging area support foundation further comprises a first embedded steel plate 25 and a second embedded steel plate 26; the first embedded steel plate 25 is embedded on the front side outer wall column 11 of the main structure 10, the first embedded steel plate 25 comprises a first steel plate 251 welded with the lower end of the first steel diagonal brace 22 and a first steel bar 252 extending to the inside of the front side outer wall column 11 of the main structure 10, the outer surface of the first steel plate 251 is flush with the surface of the front side outer wall column 11 of the main structure 10, a plurality of first through holes 253 are arranged in an array on the first steel plate 251, the number of the first steel bars 252 corresponds to the number of the first through holes 253, the outer ends of the first steel bars 252 are arranged in the first through holes 253 and welded with the first steel plate 251; the second embedded steel plate 26 is embedded on the rear side outer wall column 12 of the main structure 10, the second embedded steel plate 26 comprises a second steel plate 261 welded with the lower end of the second steel diagonal brace 23 and a second steel bar 262 extending to the inside of the rear side outer wall column 12 of the main structure 10, the outer surface of the second steel plate 261 is flush with the surface of the rear side outer wall column 12 of the main structure 10; a plurality of second through holes 263 are arranged in an array on the second steel plate 261, the number of the second steel bars 262 corresponds to the number of the second through holes 263, the outer ends of the second steel bars 262 are arranged in the second through holes 263 and welded with the second steel plate 261.

[0041] It can be understood that the first embedded steel plate 25 and the second embedded steel plate 26 are pre-positioned and embedded when the main structure 10 is poured. The first steel bars 252 are arranged in the array through holes of the first steel plate 251, the steel bars are welded with the steel plate at the ends and extend to the inside of the outer wall column, forming a three-dimensional anchoring system. The second steel plate 261 forms a combined anchoring structure with the second steel bars 262 in the same way. When the lower end of the steel diagonal brace is welded with the embedded steel plate, the square steel section is in surface contact with the steel plate, and the arrayed steel bar group can effectively disperse the welding stress. The structure makes the connection joint of the steel diagonal brace and the main structure 10 have multiple force transmission paths, which can adapt to the complex stress state of wind load and construction load in high-altitude environment. Through the above technical scheme, the reliable connection problem of the high-altitude large overhanging construction platform support system and the main structure 10 is effectively solved. The combined anchoring mode of the embedded steel plate and the arrayed steel bar can ensure that the steel diagonal brace remains stable when bearing dynamic construction load, and the cooperation of the square steel member and the multiple welded joints makes the support system have sufficient bending resistance and fatigue resistance, meeting the construction requirements of the large-span concrete corridor in 95-meter high-altitude environment.

[0042] Exemplarily, the gable area supporting foundation 30 further comprises a third embedded steel plate 33, a fourth embedded steel plate 34, a fifth embedded steel plate 35 and steel supports 36; the third embedded steel plate 33 is embedded on the outer side of the outer wall column 13 of the two main body structures 10, and the steel corbel 31 is welded on the third embedded steel plate 33; the fourth embedded steel plate 34 is embedded on the inner side of the outer wall column 13 of the two main body structures 10; the fifth embedded steel plate 35 is embedded on the surface of the inner wall column 14 inside the main body structure 10 and horizontally opposite to the fourth embedded steel plate 34; and the steel supports 36 are arranged in the adjacent floors of the steel corbel 31 respectively, at least one steel support 36 is welded on the bottom surface of the steel beam 21, one end of the steel support 36 is welded with the fourth embedded steel plate 34, and the other end of the steel support 36 is welded with the fifth embedded steel plate 35.

[0043] It can be understood that the steel support 36 can be realized by I-shaped steel or square steel, and the bending resistance of the I-shaped steel section can reduce the deformation of the structure. The third embedded steel plate 33 is embedded on the outer side of the outer wall column as the mounting base of the steel corbel 31, and the steel corbel 31 bears the vertical load of the Bailey bracket 40 after welding. The fourth embedded steel plate 34 and the fifth embedded steel plate 35 form corresponding anchoring points between the outer wall column 13 and the inner wall column 14, the steel support 36 is connected with the two through double V-groove welding, forming a horizontal force transmission path across the inner and outer walls, and dispersing the construction load transmitted by the Bailey bracket 40 to the inside of the building main body structure 10. When the steel corbel 31 bears the load, part of the force is transmitted to the inner wall column 14 of the main body structure 10 through the steel support 36, and the remaining force is dispersed through the outer wall column itself. The steel support 36 located at the bottom of the steel beam 21 can directly resist the lateral load and vertical load of the cantilever beam and disperse to the inside of the building main body structure 10, effectively controlling the deflection of the cantilever end. Through the above technical scheme, the embodiment of the present application realizes the reliable connection of the high-altitude large cantilever construction platform and the building main body structure 10, the steel support 36 system effectively transmits the local load to the bearing structure inside the building, ensures the stability of the gable area Bailey bracket 40 in the concrete pouring process, and solves the safety problem of the support system of the large-span corridor construction under the 95-meter high-altitude environment.

[0044] Exemplarily, the steel corbel 31 is centrally arranged in the middle part of the third embedded steel plate 33, the steel corbel 31 comprises a top plate 311, a bottom plate 312 and a plurality of vertical plates 313, the top plate 311 and the bottom plate 312 are arranged in parallel, the plurality of vertical plates 313 are arranged at intervals between the top plate 311 and the bottom plate 312, and the upper end of the vertical plate 313 is welded with the top plate 311, and the lower end of the vertical plate 313 is welded with the bottom plate 312; the top plate 311, the bottom plate 312 and the vertical plate 313 are welded with the third embedded steel plate 33 respectively.

[0045] It can be understood that the plurality of vertical plates 313 form a grid-shaped support system between the top plate 311 and the bottom plate 312, and the cavity structure formed by welding can effectively improve the bending stiffness and torsional performance. The interval arrangement of the vertical plates 313 reduces the self weight of the component while ensuring the structural strength, and the interval distance can be adjusted according to the load calculation result. The parallel arrangement of the top plate 311 and the bottom plate 312 ensures uniform stress, and the overall structure formed by welding with the vertical plate 313 can adapt to wind vibration load and construction dynamic load under high-altitude environment. When the steel bracket 31 is installed, the end edges of the top plate 311, the bottom plate 312 and the vertical plate 313 are in contact with the surface of the third embedded steel plate 33. By welding the end edges of each plate member with the embedded steel plate, a continuous force transmission path is formed. The end of the top plate 311, which serves as the bearing surface of the Bailey frame 40, is welded to ensure that the vertical load is effectively transmitted to the main structure 10. The vertical plate 313 forms a stable box section after welding, which can withstand the bending moment transmitted by the Bailey frame 40. The welding of the bottom plate 312 enhances the overall bending stiffness of the bracket and prevents local deformation. The weld between the end of each plate member and the embedded steel plate forms a closed force transmission ring, avoiding stress concentration.

[0046] For example, the third embedded steel plate 33 includes a third steel plate 331 welded with the steel bracket 31 and a third steel bar 332 extending into the interior of the outer wall column 13 on the opposite wall side of the two main structures 10. The outer surface of the third steel plate 331 is flush with the outer side of the outer wall column 13 on the opposite wall side of the two main structures 10. A plurality of third through holes 333 are arranged in an array on the third steel plate 331. The number of third steel bars 332 corresponds to the third through holes 333. One end of the third steel bar 332 is arranged in the third through hole 333 and welded with the third steel plate 331. The fourth embedded steel plate 34 includes a fourth steel plate 341 welded with the steel support 36 and a fourth steel bar 342 extending into the interior of the outer wall column 13 on the opposite wall side of the two main structures 10. The outer surface of the fourth steel plate 341 is flush with the inner side of the outer wall column 13 on the opposite wall side of the two main structures 10. A plurality of fourth through holes 343 are arranged in an array on the fourth steel plate 341. The number of fourth steel bars 342 corresponds to the fourth through holes 343. One end of the fourth steel bar 342 is arranged in the fourth through hole 343 and welded with the fourth steel plate 341. The fifth embedded steel plate 35 includes a fifth steel plate 351 welded with the steel support 36 and a fifth steel bar 352 extending into the interior of the inner wall column 14 of the main structure 10. The outer surface of the fifth steel plate 351 is flush with the surface of the inner wall column 14 of the main structure 10. A plurality of fifth through holes 353 are arranged in an array on the fifth steel plate 351. The number of fifth steel bars 352 corresponds to the fifth through holes 353. One end of the fifth steel bar 352 is arranged in the fifth through hole 353 and welded with the fifth steel plate 351.

[0047] It can be understood that, in the main structure 10 construction stage, the third steel plate 331 is integrally anchored with the outer wall column 13 concrete through the third steel bar 332, and the steel corbel 31 is welded on the surface of the third steel plate 331 to realize reliable connection; the adjacent structure surface is respectively embedded with the fourth and fifth steel plates, and the steel support 36 is connected with the two steel plates through welding at both ends to form a complete force transmission path. In terms of structure, the third steel bar 332 is welded with the steel plate after passing through the third through hole 333, and the fourth and fifth steel bars are also welded with the steel plate after passing through the corresponding through hole, so that the embedded steel plate and the structure constitute an integral stress system. The core of this structure is to form a three-dimensional anchoring system of the embedded steel plate and the main structure 10 through the through hole array and the steel bar welding structure: the steel bar is welded with the steel plate after passing through the hole to form mechanical interlocking, and multiple anchoring mechanisms are formed in cooperation with the concrete gripping effect, which significantly improves the reliability of the node connection. Compared with the conventional single-sided welded embedded part, this structure can effectively improve the shear bearing capacity of the connection node of the steel corbel 31 and the steel support 36, avoid the risk of instability of the support system in high-altitude operation; at the same time, the reliable connection of the steel support 36 and the embedded steel plate ensures the stability of the force transmission path, guarantees the overall stiffness of the gable area support system, prevents the displacement of the steel corbel 31 under dynamic load, and provides safety protection for high-altitude concrete corridor construction.

[0048] Exemplarily, the aerial corridor construction platform of the embodiment of the present application further comprises a reinforcing steel plate 37, which is embedded in the inner side of the opposite wall side outer wall column 13 of the two main structures 10 and horizontally opposite to the third steel plate 331. The outer surface of the reinforcing steel plate 37 is flush with the inner side of the opposite wall side outer wall column 13 of the two main structures 10, and a plurality of arrayed connection through holes are formed on the reinforcing steel plate 37. The number of the connection through holes corresponds to the third steel bar 332, and the end of the third steel bar 332 away from the third steel plate 331 is embedded in the connection through hole and welded with the reinforcing steel plate 37.

[0049] It can be understood that during the construction stage of the main structure 10, the third steel plate 331 is embedded on the outer side of the outer wall column 13, and the reinforcing steel plate 37 is embedded on the inner side of the outer wall column 13 in a horizontal alignment manner. After the third steel bar 332 penetrates into the inner part of the outer wall column 13 from the third steel plate 331, it continues to extend to the position of the reinforcing steel plate 37 and penetrates through the connecting through hole, and finally is fixed with the reinforcing steel plate 37 through welding. The double-steel-plate clamping structure formed thereby can effectively constrain the shear deformation of the outer wall column 13 when bearing the load of the steel corbel 31. For example, when the steel corbel 31 bears the construction load transmitted by the bailey truss 40, the third steel plate 331 and the reinforcing steel plate 37 form a cooperative force through the third steel bar 332, converting the local concentrated load into stress distributed along the outer wall column section, avoiding cracks caused by stress concentration in the concrete structure. Thus, through the cooperative action of the inner and outer steel plates and the penetrating steel bars, the embodiment of the application forms a spatial force system, optimizes the load transmission path from single-side anchoring to bidirectional constraint, significantly improves the shear performance and durability of the embedded joint, ensures the stability of the steel corbel 31 when bearing dynamic construction load, avoids deformation of the support system caused by single-side anchoring failure, and provides reliable structural protection for high-altitude concrete corridor construction.

[0050] Exemplarily, the part of the Bailey frame 40 erected on the cushion support 24 and extending into the main body structure 10 corresponds to the bottom of the lower floor 15, and a protective support structure 70 is arranged at the bottom of the lower floor 15; the protective support structure 70 comprises a support ridge 71, a sixth embedded steel plate 72, a seventh embedded steel plate 73, a third steel diagonal brace 74 and a protective seat cushion 75; the support ridge 71 is cast in the space surrounded by the floor 15, the outer structural beam 16 and the inner structural beam 17, and the support ridge 71 is arranged in length, and the two ends of the length direction of the support ridge 71 are connected with the outer structural beam 16 and the inner structural beam 17 respectively; the bottom surface of the support ridge 71 is flush with the bottom surface of the inner structural beam 17; the sixth embedded steel plate 72 is embedded at the bottom of the support ridge 71; the seventh embedded steel plate 73 is embedded on the structural wall column below the inner structural beam 17; the upper end of the third steel diagonal brace 74 is welded with the sixth embedded steel plate 72, and the lower end of the third steel diagonal brace 74 is welded with the seventh embedded steel plate 73. Among them, the sixth embedded steel plate 72 comprises a sixth steel plate 721 welded with the third steel diagonal brace 74 and a sixth steel bar 722 extending to the inside of the support ridge 71, a plurality of sixth through holes 723 are arranged in array on the sixth steel plate 721, the number of the sixth steel bars 722 corresponds to the number of the sixth through holes 723, and one end of the sixth steel bar 722 is arranged in the sixth through hole 723 and welded with the sixth steel plate 721. The seventh embedded steel plate 73 comprises a seventh steel plate 731 welded with the third steel diagonal brace 74 and a seventh steel bar 732 extending to the inside of the structural wall column below the inner structural beam 17, a plurality of seventh through holes 733 are arranged in array on the seventh steel plate 731, the number of the seventh steel bars 732 corresponds to the number of the seventh through holes 733, and one end of the seventh steel bar 732 is arranged in the seventh through hole 733 and welded with the seventh steel plate 731; the protective seat cushion 75 is arranged between the bottom surface of the Bailey frame 40 and the top surface of the floor 15.

[0051] It can be understood that the protective seat pad 75 refers to a protective pad layer arranged between the falsework 40 and the top surface of the floor 15, which can be realized by a wooden board. When the falsework 40 extends into the main structure 10, the floor 15 below it needs to bear a local concentrated load, and the arrangement of the protective seat pad 75 can disperse the concentrated load transmitted by the falsework 40 through elastic deformation and absorb construction vibration, thereby reducing the impact of the impact force on the floor 15. The support counter 71 refers to a concrete reinforcing structure poured in the enclosed area of the floor 15 and the structure beam, and the purpose of the continuous arrangement is to form a continuous support belt, thereby ensuring the integrity of the load transmission path between it and the structure beam. When pouring the support counter 71, the installation height of the formwork is controlled to make the bottom surface completely aligned with the bottom of the inner structure beam 17, and the horizontal continuous support surface formed thereby can uniformly disperse the load transmitted by the falsework 40 to the contact area of the structure beam and the support counter 71, thereby avoiding stress concentration in the local area of the structure beam due to the misalignment of the bottom surface. The sixth embedded steel plate 72 is embedded in the bottom of the support counter 71, and the sixth through hole 723 is welded with the sixth steel bar 722 to form an upper end anchorage node for connecting the third steel diagonal brace 74. The seventh embedded steel plate 73 is embedded in the lower structure wall column, and the sixth through hole 723 is welded with the seventh steel bar 732 to form a lower end anchorage node for connecting the third steel diagonal brace 74. The third steel diagonal brace 74 connects the sixth embedded steel plate 72 and the seventh embedded steel plate 73 at an inclined angle, forming an inclined force transmission path from the support counter 71 to the lower wall, effectively sharing the vertical load borne by the floor 15. Thus, the combination of the protective seat pad 75, the support counter 71, the embedded steel plate and the third steel diagonal brace 74 in the embodiment of the application achieves multiple technical effects: the protective seat pad 75 can alleviate the impact of concentrated load on the floor 15 and reduce the influence of construction vibration; the counter and the embedded steel plate system enhance the local bearing capacity, and the steel diagonal brace structure establishes a three-dimensional force transmission network, so that the load is reasonably dispersed along the inclined path to the lower bearing wall, thereby avoiding cracks in the floor 15 due to local overload. The above technical solution accurately solves the problem of insufficient bearing pressure of the floor 15 at the support part of the falsework 40 in the construction of the high-altitude corridor, ensures the safety and precision of the high-altitude cantilever construction, and avoids the risk of structural damage caused by traditional temporary support.

[0052] For example, the steel beam 21 is provided with overlapping segments staggered with the opposite wall side outer wall columns 13 of the two main structures 10, and the lower part of the overlapping segments is provided with a steel support column 80 embedded in the opposite wall side outer wall columns 13 of the two main structures 10 and supported on the bottom surface of the steel beam 21; the outer periphery of the steel support column 80 is uniformly distributed with a plurality of studs 81.

[0053] It can be understood that the coinciding section of the steel beam 21 and the outer wall column 13 refers to the area where the steel beam 21 crosses the outer wall column 13 in space when passing through the main structure 10, which can be determined by three-dimensional modeling to realize the position relationship between the arrangement path of the steel beam 21 and the outer wall column 13. The coinciding section of the steel beam 21 is realized by pre-buried method during the construction stage of the main structure 10, which can ensure the stress continuity of the steel beam 21 when passing through the structure. The steel support 80 refers to a vertically arranged steel support member pre-buried in the inner part of the outer wall column 13 during the construction stage of the main structure 10, which can be realized by a steel pipe concrete column, and the downward extension length is not less than 2 meters, and the top end directly supports the bottom surface of the steel beam 21, which can share the concentrated load of the steel beam 21 in the coinciding area. The stud 81 refers to a cylindrical shear connector welded on the surface of the steel member, which can be uniformly arranged at an interval of 200 mm by using a stud 81 with a diameter of 19 mm and a height of 10 mm, and the grip force between the steel support 80 and the concrete outer wall column 13 is enhanced to prevent relative sliding between the two. Therefore, the pre-buried steel support 80 and stud 81 of the embodiment of the present application can realize the connection between the steel beam 21 and the main structure 10 with higher reliability and durability, and are particularly suitable for the construction of large-span corridors of super high-rise buildings.

[0054] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, several improvements and replacements can be made, and these improvements and replacements should be considered as the protection scope of the present application.
