Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an air-suspended steel corridor separation device and an air-suspended steel corridor. Background Art

[0002] As an important structural form in modern urban architecture, the steel corridor in the air has various functions. The steel corridor in the air plays an important role in alleviating traffic pressure, expanding urban development space, enhancing building functions and quality, strengthening seismic performance, and facilitating construction and maintenance. They are not only bridges connecting spaces and functions, but also essential elements for demonstrating building quality and creating a comfortable living environment. For example, in commercial buildings, steel structure corridors are often used to connect different functional areas such as shopping malls, office buildings, and hotels, providing convenient access and streamline organization, thereby reducing ground traffic flow and improving traffic efficiency.

[0003] In the design and implementation of steel corridors, especially those in the air, in order to effectively cope with the deformation of the main structure caused by environmental factors such as temperature changes and wind loads, as well as the deformation caused by long-term use, and at the same time ensure the safety and stability of the corridor structure itself, expansion joints are often set between the corridors in traditional designs to allow a certain degree of relative displacement and prevent the structure from being damaged due to excessive stress. Currently, many corridor construction plans tend to adopt the method of separating the lifting points, that is, each corridor component or section is lifted independently without interference. This method results in a long construction period because each component needs to be lifted and installed separately, making it difficult to ensure the accuracy and flatness during their aerial docking, difficult to control the overall flatness of the corridor, and a large amount of cantilever tooling brackets are used, increasing the construction cost and complexity. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the existing technology, such as the long construction period for separately lifting and installing multiple corridors, difficult control of the overall flatness of the corridor, and a large amount of cantilever tooling brackets used, the utility model provides an air-suspended steel corridor separation device.

[0005] The technical solution of the utility model is as follows:

[0006] An air-suspended steel corridor separation device is used for temporarily strengthening and connecting each corridor so that multiple corridors are connected into a whole. It includes an upper connecting plate, a reinforcing plate, and a lower connecting plate. The upper end of the reinforcing plate is fixedly connected to the lower surface of the upper connecting plate, and the lower end is fixedly connected to the upper surface of the lower connecting plate. The upper connecting plate and the lower connecting plate are arranged in parallel. The reinforcing plate is perpendicular to the upper connecting plate and the lower connecting plate. The upper and lower ends of the reinforcing plate are respectively located at the central positions of the upper connecting plate and the lower connecting plate. There is a serrated joint surface at the central position of the reinforcing plate in the vertical direction, and the reinforcing plate is divided into left and right parts by the serrated joint surface. Hollow holes are provided at the serrated edges. The long side of the hollow hole coincides with one tooth edge of the serration, and the wide side of the hollow hole coincides with the straight line where the two tooth edges connected to this tooth edge are located. From top to bottom, there are multiple hollow holes and they are arranged at intervals. The area of the opening of the hollow hole gradually increases.

[0007] Further, in one embodiment, the inclination angle of the hollow hole is 45 degrees.

[0008] Further, in one embodiment, the hollow hole is a quadrilateral hole.

[0009] Further, in one embodiment, the distance between the two long sides of the uppermost hollow hole is 3 mm, and the distance between the two long sides of the lowermost hollow hole is 25 mm.

[0010] Further, in one embodiment, both the upper connecting plate and the lower connecting plate are H-shaped steel, and the reinforcing plate is connected to the web of the H-shaped steel.

[0011] Further, in one embodiment, the thickness of the web of the H-shaped steel is 32 mm.

[0012] Further, in one embodiment, dividing lines are drawn on the surfaces of the reinforcing plate, the upper connecting plate, and the lower connecting plate. The dividing lines are the intersection lines of the surface that vertically and symmetrically divides the reinforcing plate and the surfaces of the upper connecting plate, the reinforcing plate, and the lower connecting plate. The dividing lines are used to indicate the gas cutting positions of the air-suspended steel corridor separation device after suspension.

[0013] Further, in one embodiment, the left side of the reinforcing plate is flush with the left sides of the upper connecting plate and the lower connecting plate, and the right side of the reinforcing plate is flush with the right sides of the upper connecting plate and the lower connecting plate.

[0014] In view of the above deficiencies, the present invention provides an air-suspended steel corridor separation device.

[0015] The technical solution is as follows:

[0016] An air-suspended steel connecting corridor includes a first connecting corridor and a second connecting corridor. There is an expansion joint between the first connecting corridor and the second connecting corridor. An air-suspended steel connecting corridor separation device as described above is provided at the position of the expansion joint. The left and right ends of the air-suspended steel connecting corridor separation device are welded to the first connecting corridor on one side and to the second connecting corridor on the other side, so that the first connecting corridor and the second connecting corridor are connected into a whole.

[0017] Further, in an embodiment, within the expansion joint, there are four air-suspended steel connecting corridor separation devices, which are respectively arranged at the four corner positions opposite to each other between the first connecting corridor and the second connecting corridor.

[0018] For the air-suspended steel connecting corridor separation device of the present utility model according to the above solution, its beneficial effect lies in that the reinforcing plate connects the upper connecting plate and the lower connecting plate, enabling the existence of the air-suspended steel connecting corridor separation device as a whole, which is convenient for the temporary reinforcement connection between two adjacent connecting corridors. Since the air-suspended steel connecting corridor separation device needs to be removed after the overall lifting of the steel connecting corridor is completed, so that the stress between the two connecting corridors can be slowly released. The reinforcing plate is divided into left and right parts by the serrated joint surface, and the opening area of the hollow hole gradually increases from top to bottom, thus avoiding uneven stress release on both sides of the connecting corridors during separation, and thus not generating a large stress mutation, reducing the risk of stress mutation.

[0019] The air-suspended steel connecting corridor of the present utility model uses the above air-suspended steel connecting corridor separation device to temporarily reinforce and connect two connecting corridors, enabling the two connecting corridors to be lifted as a whole for construction and installation, reducing the number of tooling suspension points set in the middle of the overhang, reducing material consumption, and helping to shorten the construction period. At the same time, the overall lifting ensures the flatness of the connecting corridor as a whole and improves the flatness quality control of the connecting corridor.

[0030] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] At present, aerial steel link corridors are increasingly used in super high-rise structures with more and more unique shapes. The steel link corridors are often installed by the construction method of integral lifting. During the construction stage, especially when the construction method of integral lifting and positioning is adopted, these scattered link corridor components need to be temporarily spliced into a whole so as to carry out the integral lifting operation uniformly and safely. This temporary splicing not only requires sufficient structural strength to withstand all the forces during the lifting process, but also needs to ensure that it can be easily separated after the lifting is completed so as to restore the function of the expansion joint without affecting the final use state of the link corridor.

[0032] As Figures 1-3 shown, an embodiment of an aerial cantilever steel link corridor separation device is used for temporarily strengthening and connecting each link corridor so that multiple link corridors are connected into a whole. The aerial cantilever steel link corridor separation device includes an upper connecting plate 100, a reinforcing plate 300 and a lower connecting plate 200. The upper end of the reinforcing plate 300 is fixedly connected to the lower surface of the upper connecting plate 100, and the lower end is fixedly connected to the upper surface of the lower connecting plate 200. The upper connecting plate 100 and the lower connecting plate 200 are arranged in parallel. The reinforcing plate 300 is perpendicular to the upper connecting plate 100 and the lower connecting plate 200. The reinforcing plate 300 is located at the central position between the upper connecting plate 100 and the lower connecting plate 200. The reinforcing plate 300 has saw teeth and is divided into left and right two parts by the saw teeth. A hollow hole 310 is provided at the edge of the saw teeth. The long side of the hollow hole 310 coincides with one tooth edge of the saw teeth, and the wide side of the hollow hole 310 coincides with the straight line where the two tooth edges connected to the tooth edge are located. The hollow holes 310 are multiple and arranged at intervals from top to bottom. The area of the opening of the hollow hole 310 gradually increases.

[0033] In this embodiment, the reinforcing plate 300 connects the upper connecting plate 100 and the lower connecting plate 200, making the whole aerial cantilever steel link corridor separation device exist, which is convenient for the temporary strengthening connection between two adjacent link corridors. Since the aerial cantilever steel link corridor separation device needs to be removed after the integral lifting of the steel link corridor is completed so that the stress between the two link corridors can be slowly released, the reinforcing plate 300 is divided into left and right two parts by the saw-tooth joint surface, and the opening area of the hollow hole 310 gradually increases from top to bottom, thus avoiding uneven stress release on both sides of the link corridors during the division, and thus not generating a large stress mutation and reducing the risk of stress mutation. It should be particularly noted that when the aerial cantilever steel link corridor separation device is in use, it is necessary to ensure that the opening area of the hollow hole 310 gradually increases from top to bottom, and the spatial position relationship between the upper connecting plate 100 and the lower connecting plate 200 cannot be changed.

[0034] In this embodiment, both the upper connecting plate 100 and the lower connecting plate 200 are H-shaped steel. The reinforcing plate 300 is connected to the web of the H-shaped steel. The web of the upper H-shaped steel is the upper connecting plate 100, and the web of the lower H-shaped steel is the lower connecting plate 200. Therefore, the web of the upper H-shaped steel connected to the reinforcing plate 300 is the upper connecting web 110, and the web of the lower H-shaped steel connected to the reinforcing plate 300 is the lower connecting web 210. H-shaped steel has the advantages of large section modulus, light weight, and metal saving, which can reduce the building structure weight by 30-40%. At the same time, it has low cost, high precision, and small residual stress, without the need for expensive welding materials and weld inspection, saving the production cost of steel structures. During the welding connection between two adjacent corridors, the welding cost can be effectively reduced.

[0035] As Figure 3 shown, in one embodiment, the inclination angle of the hollow hole 310 is 45 degrees, that is, the inclination angle of the serrated edge of the serrated cross-section is 45 degrees. Among them, the hollow hole 310 is a quadrilateral hole. In particular, the hollow hole 310 at the topmost layer is the vertical line segment part matching the serrated interface, and the hollow hole 310 at this place is a quadrilateral hole with two right angles. The hollow holes 310 below are all rectangular holes.

[0036] In one embodiment, the thickness of the web of the selected H-shaped steel is 32 mm. The distance between the two long sides of the hollow hole 310 at the topmost layer is 3 mm. The second hollow hole 310 from the top to the last hollow hole 310 are all rectangular holes, and the length of each rectangular hole is 71 mm. The widths of the rectangular holes in sequence downward are 6, 12, 15, 20, and 25 mm respectively. In other embodiments, according to actual production requirements, the specifications of the H-shaped steel and the length and width of the hollow holes 310 on the reinforcing plate 300 can be adjusted adaptively, so that the air-suspended steel corridor separation device meets the temporary reinforcement standard of the air-suspended steel corridor.

[0037] As Figure 1 shown, in one embodiment, dividing lines 400 are drawn on the surfaces of the reinforcing plate 300, the upper connecting plate 100, and the lower connecting plate 200. The dividing lines 400 are the intersection lines of the plane that is perpendicular to the reinforcing plate 300 and symmetrically divides the reinforcing plate 300 left and right with the surfaces of the upper connecting plate 100, the reinforcing plate 300, and the lower connecting plate 200. The dividing lines 400 are used to indicate the gas cutting positions of the air-suspended steel corridor separation device after suspension. The dividing lines 400 mark the positions for cutting the air-suspended steel corridor separation device, facilitating the removal of the air-suspended steel corridor separation device after the overall lifting of the air-suspended steel corridor. When the operator cuts, only need to cut along the dividing lines 400, without the need to estimate the cutting position, preventing the cutting position deviation that may be caused by the operator's unfamiliarity, and preventing the uneven stress release between the two adjacent corridors.

[0038] As Figure 4As shown, in one embodiment, the other structures are the same as those in the above embodiment. In this embodiment, the left side of the reinforcing plate 300 is flush with the left sides of the upper connecting plate 100 and the lower connecting plate 200, and the right side of the reinforcing plate 300 is flush with the right sides of the upper connecting plate 100 and the lower connecting plate 200. The connection length between the reinforcing plate 300 and the upper connecting plate 100 and the lower connecting plate 200 is increased to ensure the stability of the structure of the air-suspended steel corridor separation device, and it is not prone to deformation or damage when not in use.

[0039] As Figure 5 shown, in an embodiment of an air-suspended steel corridor, the air-suspended steel corridor includes a first corridor 1 connected to the A tower base 5 and a second corridor 2 connected to the B tower base 6. There is an expansion joint 3 between the first corridor 1 and the second corridor 2. An air-suspended steel corridor separation device 4 as in the above embodiment is provided at the position of the expansion joint 3. In this embodiment, there are four air-suspended steel corridor separation devices 4, which are respectively arranged at the four opposite corners of the first corridor 1 and the second corridor 2. The left and right ends of the air-suspended steel corridor separation device 4 are welded to the first corridor 1 on one side and welded to the second corridor 2 on the other side, so that the first corridor 1 and the second corridor 2 are connected into a whole, so that the first corridor 1 and the second corridor 2 form a whole on the ground. The corresponding positions are reinforced and connected by using the air-suspended steel corridor separation device 4, so that the steel corridors are temporarily connected into a whole to meet the lifting requirements, so as to realize the overall suspension and lifting installation of the corridors. Connecting the two corridors into a whole on the ground can effectively control the flatness of the overall corridor, make the flatness of the overall corridor easy to control, and can effectively reduce the usage amount of the cantilever tooling support, effectively reduce the use of auxiliary tools, reduce materials, and reduce costs. At the same time, the overall lifting is completed in one hoisting, which can significantly shorten the construction period.

[0040] When the first corridor 1 and the second corridor 2 are integrally suspended and lifted to the set position and are respectively suspended and connected and fixed to the A tower base 5 and the B tower base 6 on both sides, the air-suspended steel corridor separation device 4 can be gas-cut and segmented to gradually release the stress, avoid uneven stress release on both sides of the corridor, and avoid large vibrations caused by stress mutation.

[0041] In other embodiments, the positional relationship between pedestal A 5 and pedestal B 6 can change according to the actual occurrence position, and the shape or position of the connecting corridor will also change accordingly. The first connecting corridor 1 and the second connecting corridor 2 are the connecting corridor components of pedestal A 5 and pedestal B 6. When the shape or position of the connecting corridor changes, the shape and number of the connecting corridor components will also be adjusted as needed. When more than two connecting corridor components need to be connected, there are respective expansion joints 3 between the two connected connecting corridor components. The welding position of the aerial cantilever steel connecting corridor separation device 4 remains unchanged, which is also within the expansion joints 3 of two adjacent connecting corridors. Generally, it is welded to the four corner positions opposite to each other of the two connecting corridors, and multiple connecting corridor components are temporarily fixedly connected into a whole to facilitate overall hoisting and lifting, which is beneficial to shortening the construction period, increasing the overall flatness of the connecting corridor, and reducing the difficulty of lifting operations.

[0042] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of the present utility model.

[0043] The above has made an exemplary description of the patent of the present utility model in conjunction with the drawings. Obviously, the implementation of the patent of the present utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the patent of the present utility model, or the concept and technical solution of the patent of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
