[0002] Floating slab refers to the part of the roof (floor) that protrudes from the outer wall, mainly for the purpose of facilitating drainage and protecting the outer wall. At present, if the main structure is concrete, the floating slab generally adopts cast-in-place concrete floating slab or steel structure floating slab. If the main structure is steel structure, the floating slab generally adopts aluminum plate floating slab or steel structure floating slab structure. When a building with a steel structure as the main body is provided with a floating slab structure, the floating slab structure is also a metal structure, that is, the structural form of the floating slab is relatively simple. The present application provides a concrete floating slab structure with a steel frame main body, which aims to solve the problem that the floating slab structure of a steel frame building cannot be provided with a concrete floating slab.

[0004] The utility model provides a concrete floating slab structure with a steel frame body, comprising a frame steel beam, a supporting steel beam, and a floating slab structure.

A second stiffening plate is provided along the length of the cantilever beam at its end proximate to the first support beam, and the second stiffening plate is detachably connected to the first stiffening plate of the first support beam, which is distal to the frame steel beam.

[0008] In some embodiments, the cantilever assembly further comprises a turnbuckle for adjusting the tightness of the inclined rope.

[0009] The inclined rope is connected to the cantilever beam via a turnbuckle. Alternatively, both ends of the turnbuckle are connected to the inclined rope.

[0010] In some embodiments, the supporting steel beam also includes a second supporting beam, one end of which is fixedly connected to the outer side of the frame steel beam, and multiple second supporting beams are spaced apart along the length direction of the frame steel beam, and the second supporting beam is located below the first supporting beam in the vertical direction.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0032] The following combination Figures 1 to 3 , describing a concrete floating slab structure with a steel frame main body according to an embodiment of the present utility model.

[0033] like Figure 1 As shown, the present invention provides a concrete floating slab structure 100 with a steel frame body, comprising a frame steel beam 12, a support steel beam 20, and a floating slab structure 30. One end of the support steel beam 20 is fixedly connected to the outer side of the frame steel beam 12. The floating slab structure 30 is a reinforced concrete structure and includes a connecting beam 31 and a floating slab platform 32. The connecting beam 31 is cast-connected to the support steel beam 20, and the floating slab platform 32 is connected to the side of the connecting beam 31 away from the frame steel beam 12.

[0034] In this way, by fixing the supporting steel beam 20 on the outside of the steel frame body of the frame steel beam 12, and casting (anchoring) the connecting beam 31 of the floating plate structure 30 to the supporting steel beam 20, the floating plate platform 32 of the reinforced concrete structure is stably connected to the outside of the frame steel beam 12 through the connecting beam 31 and the supporting steel beam 20, thereby stably setting a floating plate structure 30 of a concrete structure on the outside of the frame steel beam 12 to solve the problem that a concrete floating plate structure 30 cannot be set in a building with a steel frame body.

[0035] Furthermore, because the reinforced concrete floating slab structure 30 and the steel structure main body are two different structural forms, the floating slab structure 30 can be installed layer by layer after the steel structure main body is laid. Alternatively, the floating slab structure 30 can be installed layer by layer while the steel structure main body is being assembled. This allows for flexible and diverse construction methods.

[0036] In addition, by setting the concrete floating slab structure 100 of the above-mentioned steel frame main body, a floating slab of a concrete structure or a floating slab of a metal structure can be set correspondingly on the outer side of the steel frame building as needed, without limitation.

[0037] In some embodiments, as Figure 1 As shown, in the concrete floating slab structure 100 with a steel frame as the main body, the steel frame 10 may include frame columns 11, frame steel beams 12 and floor decking 13. The frame steel beams 12 are supported and connected between a plurality of frame columns 11, and the frame steel beams 12 support and connect the floor decking 13 to form a structural building with the steel frame 10 as the main body. Among them, the frame columns 11 can be flexibly arranged between the reinforced concrete columns and the steel structure columns as needed. Correspondingly, the floor decking 13 can also be a reinforced concrete floor decking or a steel truss floor slab, which is not limited.

[0038] In some embodiments, as Figure 1 As shown, the support steel beam 20 includes at least one of a first support beam 21 and a second support beam 22 , and the first support beam 21 is vertically located above the second support beam 22 as an example.

[0039] One end of the first support beam 21 is fixedly connected to the outside of the frame steel beam 12. Multiple first support beams 21 are spaced apart along the length of the frame steel beam 12, and are vertically positioned near the upper side of the connecting beam 31. By providing the outwardly cantilevered first support beams 21 and anchoring them to the upper portion of the connecting beam 31, the connecting beam 31 on the outside of the frame steel beam 12 is cantilevered, and a stable connection structure is formed between the connecting beam 31 and the frame steel beam 12 via the multiple first support beams 21.

[0040] One end of the second support beam 22 is also fixedly connected to the outside of the frame steel beam 12. Multiple second support beams 22 are spaced apart along the length of the frame steel beam 12, and the second support beams 22 are vertically located below the first support beam 21, that is, the second support beams 22 are vertically arranged near the lower side of the connecting beam 31. By providing the outwardly cantilevered second support beams 22 and anchoring them to the lower portion of the connecting beam 31, the connecting beam 31 on the outside of the frame steel beam 12 is cantilevered, and a stable connection structure is formed between the connecting beam 31 and the frame steel beam 12 through the multiple second support beams 22.

[0041] For example, along the length direction of the frame steel beam 12, the plurality of first support beams 21 are arranged at intervals of 1-2 meters, such as 1.5 meters. Correspondingly, the plurality of second support beams 22 are arranged at intervals of 1-2 meters, such as 1.5 meters.

[0042] In the embodiment of the present application, taking the frame column 11 as a steel structure as an example, the frame column 11 can be any structure of square steel, channel steel and I-beam.

[0043] It should be noted that, in this application, both I-beams and H-beams can be regarded as I-beam structures.

[0044] Correspondingly, the frame steel beam 12 and the support steel beam 20 (such as the first support beam 21 and the second support beam 22) can also be set to any structure of square steel, channel steel and I-beam as needed.

[0045] Among them, when the frame steel beam 12 is fixedly connected to the first support beam 21 and the second support beam 22, the connection can be fixed by bolts, or the two components can be fixedly connected by welding, which is not limited.

[0046] For example, Figure 2 As shown, the frame steel beam 12 is provided with a plurality of frame stiffening plates 121 corresponding to at least the connecting beam 31, and the plurality of frame stiffening plates 121 are spaced apart along the length direction of the frame steel beam 12. The provision of the plurality of frame stiffening plates 121 can improve the lateral tensile strength of the frame steel beam 12.

[0047] Among them, multiple frame stiffening plates 121 are arranged at intervals of 1-2 meters along the length direction of the frame steel beam 12. For example, the distance between two adjacent frame stiffening plates 121 is 1.5 meters, and a frame stiffening plate 121 is correspondingly connected to a first support beam 21 and a second support beam 22 and other support steel beams 20.

[0048] For example, the first support beam 21, the second support beam 22, and the frame steel beam 12 are all I-beam structures. The upper flange plate of the first support beam 21 is aligned with the upper flange plate of the frame steel beam 12 and welded to each other, and the web of the first support beam 21 is aligned with the upper area of ​​a frame stiffening plate 121 of the frame steel beam 12 and welded to each other. The lower flange plate of the second support beam 22 is aligned with the lower flange plate of the frame steel beam 12 and welded to each other, and the web of the second support beam 22 is aligned with the lower area of ​​a frame stiffening plate 121 of the frame steel beam 12 and welded to each other. This ensures that the frame steel beam 12 is stably connected to the connecting beam 31 through the first support beam 21 and the second support beam 22.

[0049] In some embodiments, as Figure 2 As shown, the frame steel beam 12 is an I-beam structure. Figure 1 ) in the longitudinal direction, a side sealing plate 122 is provided on the side of the frame steel beam 12 close to the connecting beam 31, and the side sealing plate 122 is fixedly connected to the frame stiffening plate 121 and the upper and lower flange plates of the frame steel beam 12, and the end of the supporting steel beam 20 close to the frame steel beam 12 is fixedly connected to the side sealing plate 122.

[0050] It should be noted that the frame stiffening plate 121 is arranged perpendicular to the length direction of the frame steel beam 12. Take the frame steel beam 12 as an I-beam structure as an example. The upper edge of the frame stiffening plate 121 is fixedly connected to the upper flange plate of the frame steel beam 12, and the lower edge of the frame stiffening plate 121 is fixedly connected to the lower flange plate of the frame steel beam 12. One side edge of the frame stiffening plate 121 is fixedly connected to the web of the frame steel beam 12, and the other side edge of the frame stiffening plate 121 is fixedly connected to the side sealing plate 122 on the side of the web of the frame steel beam 12 close to the connecting beam 31, that is, the frame stiffening plate 121 and the side sealing plate 122 are arranged as shear keys of the frame steel beam 12, thereby increasing the structural strength at the side sealing plate 122, and helping to improve the flexibility of the arrangement of the outer supporting steel beam 20 of the frame steel beam 12.

[0051] Based on this, when connecting and installing the first support beam 21 and the second support beam 22, the ends of the first support beam 21 and the second support beam 22 can be brought into contact with the side sealing plate 122, and the first support beam 21 and the side sealing plate 122 as well as the second support beam 22 and the side sealing plate 122 can be fixedly connected through a welding process, thereby improving the flexible arrangement of the first support beam 21 and the second support beam 22 on the outside of the frame steel beam 12.

[0052] In some embodiments, as Figure 1 and Figure 2 As shown, the steel frame concrete floating slab structure 100 further includes a cantilever assembly 40, which includes a cantilever beam 41 and a diagonal cable 42. One end of each cantilever beam 41 is detachably connected to one end of the first support beam 21 and the frame steel beam 12. The end of the cantilever beam 41 away from the first support beam 21 is connected to one end of the diagonal cable 42, and the other end of the diagonal cable 42 is connected above the cantilever beam 41.

[0053] By connecting the cantilever beam 41 and the diagonal cable 42, the end of the first support beam 21 (i.e., the end away from the frame steel beam 12) can be diagonally fixed, thereby improving the cantilever strength, load capacity, and bending strength of the first support beam 21 during the pouring and solidification process of the floating plate structure 30. This avoids the side effects caused by bending and deformation of the first support beam 21 during the pouring and solidification process between the connecting beam 31 and the floating plate platform 32, and helps to improve the stability of the connection between the floating plate structure 30 and the frame steel beam.

[0054] Furthermore, because the cantilever beam 41 is detachably connected to the first support beam 21, the cantilever beam 41 and the cantilever components 40, such as the diagonal and telescopic components, can be removed after the floating slab structure 30 is cast and solidified. While maintaining the structural strength of the floating slab structure 30, the detachable cantilever components 40 help reduce the construction cost of the reinforced concrete floating slab structure 30.

[0055] The outer end of the cantilever beam 41, away from the connecting beam 31, and the frame column 11 or frame steel beam 12 above the cantilever beam 41 are provided with fixing points, each of which is provided with a connecting end. The ends of the inclined rope 42 are connected to the two connecting ends, so that the steel frame 10 can stretch and fix the outer end of the first support beam 21 through the inclined rope 42 and the cantilever beam 41, thereby increasing the load on the outer end of the first support beam 21.

[0056] In some embodiments, as Figure 1 As shown, the cantilever assembly 40 further includes a turnbuckle 43 , and the arrangement of the turnbuckle 43 facilitates adjustment of the tightness of the inclined rope 42 .

[0057] For example, the inclined rope 42 is connected to the cantilever beam 41 via a turnbuckle 43. For example, the connecting end on the cantilever beam 41 is connected to one end of the turnbuckle 43, and the other end of the turnbuckle 43 is connected to the lower end of the inclined rope 42. In this way, by turning the turnbuckle 43 in different directions to tighten or loosen the inclined rope 42, the tension of the inclined rope 42 can be adjusted, thereby conveniently adjusting the lifting force of the cantilever assembly 40 on the first support beam 21.

[0058] Correspondingly, both ends of the turnbuckle 43 can be connected to the inclined rope 42. That is, the inclined rope 42 has a two-section structure, with the upper end of the first section connected to the upper connection end, and the lower end of the first section connected to the upper end of the turnbuckle 43. The upper end of the second section is connected to the lower end of the turnbuckle 43, and the lower end of the second section is connected to the connection end of the cantilever beam 41. The tightness of the inclined rope 43 can also be adjusted through the turnbuckle 43.

[0059] The inclined rope 42 may be a rod-shaped structure or a flexible rope structure, which is not limited.

[0060] For a cantilever beam 41, cantilever beams 41 of different lengths require different numbers of inclined ropes 42 for tensioning and fixing. For example, if the length of the cantilever beam 41 is less than or equal to 1.8m, only one inclined rope 42 is required. If the length of the cantilever beam 41 is greater than 1.8m and less than or equal to 3m, two inclined ropes 42 are required, that is, the lower ends of the two inclined ropes 42 can be connected to different connection ends of the cantilever beam 41, and the upper ends of the two inclined ropes 42 can be connected to one or more connection ends above. If the length of the cantilever beam 41 is greater than 3m and less than or equal to 5m, three inclined ropes 42 are required, that is, the lower ends of the three inclined ropes 42 can be connected to the three connection ends of the cantilever beam 41, and the upper ends of the three inclined ropes 42 can be connected to one or more connection ends above.

[0061] In some embodiments, as Figure 2and Figure 3 As shown, along the length direction of the first support beam 21, first stiffening plates 211 are connected to both ends of the first support beam 21. The inner end of the first support beam 21 close to the frame steel beam 12 is fixedly connected to the frame steel beam 12 via the first stiffening plates 211. Along the length direction of the cantilever beam 41, a second stiffening plate 411 is provided at one end of the cantilever beam 41 close to the first support beam 21. The second stiffening plate 411 is detachably connected to the first stiffening plate 211 at the outer end of the first support beam 21.

[0062] For example, if both the first support beam 21 and the cantilever beam 41 are I-beam structures, the first stiffening plates 211 are welded to the two flanges and the web of the first support beam 21, and are located on opposite sides of the web. The second stiffening plates 411 are welded to the two flanges and the web of the cantilever beam 41, and are similarly located on opposite sides of the web.

[0063] At this time, if Figure 3 and Figure 4 As shown, at the outer end of the first support beam 21, aligned connecting through holes can be opened on the first stiffening cover plate 211 and the second stiffening cover plate 411, and bolts can be inserted into the two aligned plug-in through holes. By screwing nuts into the bolts, the first stiffening cover plate 211 and the second stiffening cover plate 411 are connected and fixed, and the bolts can be removed to achieve a detachable connection between the first stiffening cover plate 211 and the second stiffening cover plate 411.

[0064] In addition, an additional snap-fit ​​structure may be provided at the first stiffening sealing plate 211 and the second stiffening sealing plate 411 to cooperate with the installation method of the connecting through holes and bolts to achieve a detachable connection between the two.

[0065] Correspondingly, such as Figure 3 As shown, at the inner end of the first support beam 21, the first stiffening cover plate 211 and the side cover plate 122 are also provided with aligned connecting through holes, and bolts are inserted into the two aligned connecting through holes to connect and fix the first stiffening cover plate 211 and the side cover plate 122, and the first support beam 21 and the frame steel beam 12 can be detachably connected by detachable bolts.

[0066] Among them, a third stiffening sealing plate can also be provided at the inner end of the second support beam 22, so that the second support beam 22 can be fixedly connected to the side sealing plate 122 through the third stiffening sealing plate and bolts.

[0067] For example, the frame stiffening plate 121, the side sealing plate 122, the first stiffening sealing plate 211, the second stiffening sealing plate 411 and the third stiffening sealing plate can be set to steel plates with a thickness of 10-15 mm, such as 12 mm thick alloy steel plates or carbon steel plates.

[0068] In the above embodiment, the first stiffening sealing plate 211 and the second stiffening sealing plate 411 are arranged perpendicular to the length direction of the first support beam 21. The third stiffening sealing plate is arranged perpendicular to the length direction of the second support beam 22.

[0069] In some embodiments, as Figure 1 and Figure 2 As shown, the concrete floating slab structure 100 of the steel frame body further includes an oblique tie bar 50 , one end of which is fixedly disposed on the floor deck 13 , and the other end of which is anchored in the connecting beam 31 .

[0070] Among them, the floor decking 13 can be a reinforced concrete floor slab. At this time, the end of the inclined tie bar 50 close to the floor decking 13 is tied or welded to the steel bars inside the floor decking 13, and the other end of the inclined tie bar 50 is anchored in the connecting beam 31 to further improve the connection strength between the connecting beam 31 and the frame steel beam 12.

[0071] Alternatively, the floor deck 13 may be a steel truss floor, and the diagonal bracing bars 50 are fixedly connected to the trusses in the floor deck 13. Similarly, the diagonal bracing bars 50 anchored in the connecting beam 31 may be used to improve the connection strength between the connecting beam 31 and the frame steel beam 12.

[0072] It should be noted that the oblique tie bars 50 are disposed vertically above the connecting beam 31 to enhance the tensile fixation of the connecting beam 31. For example, the oblique tie bars 50 may be threaded steel bars with a diameter of 12 mm and spaced 150 mm apart along the length of the connecting beam 31.

[0073] For example, the floating plate structure 30 is approximately L-shaped. The vertical section of the floating plate structure 30 is a connecting beam 31, which has a rectangular cross-section of a reinforced concrete beam structure. The horizontal section of the floating plate structure 30 is a floating plate platform 32, i.e., a reinforced concrete slab structure.

[0074] The upper side of the floating platform 32 is sloped so that the end of the floating platform 32, away from the connecting beam 31, along the length of the first support beam 21 is lower, facilitating drainage. A drip line is provided along the edge of the lower side of the floating platform 32 to prevent downwardly flowing water from seeping into the lower side of the floating platform 32.

[0075] It should be noted that in the embodiment of the present application, frame stiffening plates 121 can be provided on both the inner and outer sides of the frame steel beam 12 (i.e., the side facing the connecting beam 31) spaced apart along its length. The side sealing plates 122 only need to be provided on the outer side of the frame steel beam 12 near the connecting beam 31.

[0076] Based on this, during the construction process of the concrete floating slab structure 100 of the above-mentioned steel frame main body, the main structure of the steel frame 10 is first erected. Then, the floor decking 13 of the steel truss structure and the corresponding inclined tie bars 50 are laid at the corresponding frame steel beams 12, and the first support beam 21, the second support beam 22 of the first floor and the cantilever assembly 40 connected to the first support beam 21 are erected at the same time. Subsequently, the supporting formwork of the floating slab structure 30 is laid, and the steel bars are tied inside the supporting formwork at the same time. After completing the steel bar tying process, the supporting formwork is reinforced and concrete is poured. When the concrete solidifies and reaches the preset strength, the supporting formwork and the corresponding cantilever assembly are removed, thereby forming an integrated concrete floating slab structure on the outside of the building structure of the steel frame main body.

[0077] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
