Description

Technical Field

[0001] This application relates to the field of floor support technology in building structures, and in particular to an arc-shaped floor structure. Background Technology

[0002] Curved floor structures hold an important place in modern architecture, especially in large buildings such as shopping malls and office buildings. To meet both functional and aesthetic needs, these buildings are often designed as hollow structures in circular or elliptical shapes, with the hollow center being an open area surrounded by the building structure. Curved floor structures not only enhance the artistic appeal of buildings but also effectively utilize space, increasing the building's usability and playing a significant role in driving the development of modern architectural design.

[0003] In actual construction, to support the curved floor, a steel beam structure embedded deep within the floor and arranged in a crisscross pattern is typically used. To address the challenges of transportation and hoisting, the conventional approach is to break down a single long steel beam into multiple sub-beams and connect them on-site by welding.

[0004] However, in existing technologies, the central area of ​​the floor of a hollow building is suspended in the air. After the steel beams are segmented, they are connected by welding alone, which may result in insufficient connection strength between adjacent sub-beams, especially when subjected to large loads, which can easily lead to safety hazards. Utility Model Content

[0005] To improve the connection strength of the supporting structure, this application provides an arc-shaped floor structure.

[0006] This application provides an arc-shaped floor structure, which adopts the following technical solution:

[0007] An arc-shaped floor structure includes a first steel beam, a second steel beam, and a supporting ring frame. The first steel beam is transversely arranged on both sides of the supporting ring frame, and both ends of the first steel beam are fixedly connected to the floor structure. The second steel beam is longitudinally arranged on the other two sides of the supporting ring frame, and both ends of the second steel beam are fixedly connected to the first steel beam nearby. The first and second steel beams are curved to match the curvature of the floor. The first steel beam includes multiple sub-beams, with adjacent sub-beams welded together. Two reinforcing plates are arranged between adjacent sub-beams, clamping the webs of the adjacent sub-beams. Each reinforcing plate has multiple first reinforcing rods. Both the reinforcing plates and the webs of the sub-beams have through holes for the first reinforcing rods to pass through. The structure of the second steel beam is the same as that of the first steel beam.

[0008] By adopting the above technical solution, both the first and second steel beams are composed of multiple sub-beams. Adjacent sub-beams are connected by welding, and two reinforcing plates are installed to clamp the webs of adjacent sub-beams, improving the strength of the connection. Simultaneously, multiple first reinforcing rods are installed on the reinforcing plates and fixed through holes in the webs of the reinforcing plates and sub-beams, further enhancing the connection stability between adjacent sub-beams and effectively preventing connection failure due to insufficient welding strength, ensuring the overall stability and safety of the curved floor support structure. The support ring frame is used to pre-drill holes during the floor pouring process. These pre-drilled holes in the floor are used to install translucent panels, thereby increasing the building's natural lighting effect.

[0009] Optionally, a first limiting block is provided at one end of the first reinforcing rod, and a first limiting ring is threaded onto the other end of the first reinforcing rod.

[0010] By adopting the above technical solution, a first limiting block is provided at one end of the first reinforcing rod, which can effectively prevent the first reinforcing rod from coming out of the through hole and improve the connection stability. At the same time, after tightening the first limiting ring, the two reinforcing plates clamp the web of the sub-beam, thereby improving the connection strength between adjacent sub-beams.

[0011] Optionally, a second reinforcing rod is fixedly installed at both ends of the first reinforcing rod. One of the second reinforcing rods is inserted into a through hole on a sub-beam, and the other second reinforcing rod is inserted into a through hole on another sub-beam. Multiple first reinforcing rods are arranged sequentially from top to bottom, and the length of the multiple first reinforcing rods increases sequentially from top to bottom. The through holes are gradually lowered from one end to the other and are inclined. The inclination directions of two adjacent through holes are opposite. The second reinforcing rod is inserted from the high end of the through hole. The two second reinforcing rods at the bottom are threaded with second limiting rings. Between two adjacent first reinforcing rods, the lower first reinforcing rod presses against the second reinforcing rods at both ends of the upper first reinforcing rod.

[0012] By adopting the above technical solution, after the second reinforcing rod passes through the through hole, it is screwed into the lowest reinforcing rod using the second limiting ring, thus locking the entire structure. Because the lower first reinforcing rod compresses the second reinforcing rods at both ends of the upper first reinforcing rod, this step-by-step compression method ensures that each first reinforcing rod firmly presses the reinforcing plate onto the web of the sub-beam, thereby effectively enhancing the connection strength between adjacent sub-beams and ensuring the stability and reliability of the curved floor support structure.

[0013] Optionally, the first reinforcing rod has multiple protrusions fixedly installed circumferentially on its body, and the second reinforcing rod has multiple annular grooves on its body, with the multiple annular grooves spaced apart along the length of the second reinforcing rod.

[0014] By adopting the above technical solution, the interaction between the convex strip and the annular groove can significantly improve the friction between the first and second reinforcing rods. This design allows the entire structure to be locked more securely when the second limiting ring is screwed into the second reinforcing rod located at the bottom, thereby enhancing the stability and reliability of the connection between adjacent sub-beams.

[0015] Optionally, the reinforcing plate is fixedly installed to the web of the sub-beam by welding.

[0016] By adopting the above technical solution, the periphery of the reinforcing plate is fixedly installed to the web of the sub-beam by welding, which can further improve the connection strength between the reinforcing plate and the sub-beam, making the connection between adjacent sub-beams more stable, thereby improving the stability of the entire curved floor support structure.

[0017] Optionally, the reinforcing plate has multiple reinforcing openings, and the reinforcing plate is fixedly installed to the web of the sub-beam by welding along the edge of the reinforcing openings.

[0018] By adopting the above technical solution, the reinforcing plate is opened with multiple reinforcing openings, and is fixedly installed to the web of the sub-beam by welding along the edge of the reinforcing openings. This can increase the welding area between the reinforcing plate and the web of the sub-beam and improve the strength of the weld.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The connection strength between segmented steel beams is improved by welding them together and then connecting them with reinforcing plates and first reinforcing rods;

[0021] 2. Because the first reinforcing rod located below compresses the second reinforcing rods at both ends of the first reinforcing rod above, this step-by-step compression method ensures that each first reinforcing rod firmly presses the reinforcing plate onto the web of the sub-beam, thereby effectively enhancing the connection strength between adjacent sub-beams. At the same time, only the second limiting ring located on the lowest second reinforcing rod needs to be tightened, thereby speeding up the construction process. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses an arc-shaped floor structure.

[0030] Example 1

[0031] Reference Figure 1 An arc-shaped floor structure includes a first steel beam 3, a second steel beam 4, and a supporting ring frame 1. The first steel beam 3, the second steel beam 4, and the supporting ring frame 1 are all embedded within the arc-shaped floor. The arc-shaped floor forms openings at the locations of the supporting ring frame 1 for the later installation of skylights. In a hollow building, which has an open center and is surrounded by a multi-story structure, the arc-shaped floor is typically located on the top floor. By installing skylights on the arc-shaped floor, the lighting effect of the hollow building is improved. Simultaneously, the skylights are lighter than concrete, thus reducing the strength requirements of the supporting structure on the arc-shaped floor.

[0032] The first steel beam 3 and the second steel beam 4 are curved to match the floor slab, thereby improving the overall strength of the floor slab. The first steel beam 3 is arranged laterally on both sides of the support ring frame 1, and both ends of the first steel beam 3 are fixedly connected to the floor slab. The second steel beam 4 is arranged longitudinally on both sides of the support ring frame 1, and both ends of the second steel beam 4 are fixedly connected to the first steel beam 3 nearby.

[0033] Reference Figure 1 Multiple connecting beams 2 are provided around the periphery of the support ring frame 1, and the beam bodies of the connecting beams 2 are fixedly connected to the periphery of the support ring frame 1. One end of the connecting beam 2 is fixedly connected to the beam body of the first connecting beam 2, and the other end of the connecting beam 2 is fixedly connected to the beam body of the second steel beam 4. The first steel beam 3 and the second steel beam 4 are fixed to the support ring frame 1 through the connecting beams 2, thereby facilitating the installation of the support ring frame 1.

[0034] Reference Figure 2 , Figure 3The first steel beam 3 includes multiple sub-beams 31, which are welded together with each other. Two reinforcing plates 5 are provided between two adjacent sub-beams 31. The two reinforcing plates 5 are clamped to the web of the two adjacent sub-beams 31. Each reinforcing plate 5 is provided with multiple first reinforcing rods 6. Both the reinforcing plate 5 and the web of the sub-beam 31 have through holes 8 for the first reinforcing rods 6 to pass through.

[0035] One end of the first reinforcing rod 6 is provided with a first limiting block 9, and the other end of the first reinforcing rod 6 is threaded with a first limiting ring 10. After the first reinforcing rod 6 passes through the reinforcing plate 5, the web of the sub-beam 31 and the reinforcing plate 5 in sequence, it is locked with the first limiting ring 10, thereby improving the connection strength between two adjacent sub-beams 31.

[0036] The second steel beam 4 has the same structure as the first steel beam 3, and is also reinforced with reinforcing plates 5 and first reinforcing rods 6.

[0037] The implementation principle of an arc-shaped floor structure in this application embodiment is as follows: after the two sub-beams 31 are welded, they are connected by a reinforcing plate 5 and a first reinforcing rod 6, thereby improving the strength of the connection between the two adjacent sub-beams 31.

[0038] Example 2

[0039] Reference Figure 1 The difference between this embodiment of the curved floor structure and Embodiment 1 is that both ends of the first reinforcing rod 6 are fixedly installed with second reinforcing rods 7. One second reinforcing rod 7 is inserted into a through hole 8 on a sub-beam 31, and the other second reinforcing rod 7 is inserted into a through hole 8 on another sub-beam 31. Multiple first reinforcing rods 6 are arranged sequentially from top to bottom, and the length of the multiple first reinforcing rods 6 increases sequentially from top to bottom. The through holes 8 gradually decrease in height from one end to the other and are inclined. The inclination directions of two adjacent through holes 8 along the height direction are opposite, and the second reinforcing rod 7 is inserted from the high end of the through hole 8. The two lowest second reinforcing rods 7 are threaded with second limiting rings 11. Between two adjacent first reinforcing rods 6, the lower first reinforcing rod 6 presses against the second reinforcing rods 7 at both ends of the upper first reinforcing rod 6.

[0040] The first reinforcing rod 6 has multiple protruding strips 12 fixedly installed circumferentially on its body, and the second reinforcing rod 7 has multiple annular grooves 13 on its body, which are spaced apart along the length of the second reinforcing rod 7. The protruding strips 12 and the annular grooves 13 cooperate to increase the frictional force when the first reinforcing rod 6 presses against the second reinforcing rod 7, thereby facilitating the first reinforcing rod 6 to pull the second reinforcing rods 7 at both ends of the upper first reinforcing rod 6, and thus causing the upper first reinforcing rod 6 to press the reinforcing plate 5 tightly against the web of the sub-beam 31.

[0041] The reinforcing plate 5 has multiple reinforcing openings 14. The periphery of the reinforcing plate 5 and the edges of the reinforcing openings 14 are fixedly installed to the web of the sub-beam 31 by welding, thereby improving the connection strength between the reinforcing plate 5 and the web of the sub-beam 31.

[0042] The implementation principle of the arc-shaped floor structure in this application embodiment is as follows: each second reinforcing rod 7 passes through the through hole 8, and then the lowermost second reinforcing rod 7 is tightened using the second limiting ring 11. The lower first reinforcing rod 6 then presses against the second reinforcing rods 7 at both ends of the upper first reinforcing rod 6, causing each second reinforcing rod 7 to bend. This, in turn, causes the first reinforcing rod 6 to press the reinforcing plate 5 tightly against the web of the sub-beam 31. This application only requires tightening the second limiting ring 11 on the lowermost second reinforcing rod 7, thereby accelerating the construction speed.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
