[0002] Traditional reinforced concrete platforms are usually constructed on-site, that is, most of the work is done manually on the construction site, from erecting scaffolding, supporting formwork, tying steel bars to pouring concrete. Among them, cast-in-place platform floor slabs have high rigidity, good integrity, good earthquake resistance and impact resistance, and are easy to open.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0057] In the description of the embodiments of the present application, the meanings of "multiple" and "several" are more than two (including two), unless otherwise clearly and specifically defined.

[0058] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0059] According to some embodiments of the present application, referring to Figures 1 to 18 The assembled steel frame platform structure system of the embodiment of the present application includes a steel beam module 100, a plate module 200 and a plurality of platform column modules 300; the plate module 200 includes a composite plate 210, the composite plate 210 includes a plurality of prefabricated plates 211 and a cast-in-place layer 212, the plurality of prefabricated plates 211 are laid on the steel beam module 100, and a steel truss 211a is arranged on the prefabricated plate 211 (refer to Fig.13), the cast-in-place layer 212 is arranged on the prefabricated plate 211, and the steel truss 211a is buried in the cast-in-place layer 212; the platform column module 300 includes a concrete column 310 and a steel pipe column 320, the bottom end of the concrete column 310 is fixedly connected to the ground, one end of the steel pipe column 320 is connected to the plate module 200, and the other end is connected to the concrete column 310, and the steel beam module 100 is connected to the steel pipe column 320. The steel pipe column 320 includes a steel pipe 321, the lower end of the steel pipe 321 is inserted into the concrete column 310, the steel pipe 321 includes a bottom plate 321a, a concrete column anchor bolt 311 is pre-embedded in the concrete column 310, and the bottom plate 321a is connected to the concrete column anchor bolt 311.

[0060] Among them, the concrete column 310 is made of concrete poured on site, and a concrete column anchor 311 is pre-buried at the top of the concrete column 310. The concrete column anchor 311 is connected to the bottom plate 321a of the steel pipe 321 in the steel pipe column 320 at the construction site, so that the platform column module 300 can be built on site. The steel beam module 100 and the steel pipe column 320 in the assembled steel frame platform structure system in this application are processed in the factory and connected and assembled on site. It can improve the assembly speed, shorten the construction period, and ensure the quality of the project. The same prefabricated panel 211 can also be prefabricated and processed in the factory, which can save the work of on-site formwork, realize modular manufacturing and simple on-site assembly, and good floor slab stress performance. After laying the prefabricated panel 211, a cast-in-place layer 212 is formed by cast-in-place concrete to improve the overall strength of the panel module 200.

[0061] In addition, reference Figure 5 The concrete column 310 also includes a support 312, a plurality of concrete studs 313, annular stirrups 314 and concrete column reinforcement 315; the support 312 is arranged along the extension direction of the concrete column 310, and the plurality of concrete studs 313 are arranged along the extension direction of the steel pipe 321, and are arranged at intervals in the circumference of the steel pipe 321, and are buried in the concrete column 310 as the concrete column 310 is poured, so as to strengthen the structure. The annular stirrups 314 are arranged in the circumference of the concrete column anchor bolt 311, and are used to tighten the concrete column anchor bolt 311. In addition, a concrete column reinforcement 315 is also arranged in the concrete column 310, which can also improve the structural performance of the concrete column 310.

[0062] refer to Figure 3 , Figure 4 and Fig.10 In other embodiments, the steel pipe column 320 includes a plurality of outer ring plates 322 and a plurality of steel column stiffening plates 323. The plurality of outer ring plates 322 are sleeved on the upper end of the steel pipe 321 at intervals along the extension direction of the steel pipe 321 to form a connecting end 324 matching the cross-section of the steel beam module 100. The plurality of steel column stiffening plates 323 are arranged at intervals along the circumference of the steel pipe 321 and connected to the outer ring plates 322.

[0063] Specifically, the outer ring plate 322 is prefabricated in the factory, and after being sleeved on the upper end of the steel pipe 321 on site, it is further welded and connected on site to prevent the outer ring plate 322 from sliding relative to the steel pipe 321. Similarly, the steel column stiffening plate 323 is also welded and connected to the outer ring plate 322 and the steel pipe 321 on site. Since the outer ring plate 322 and the steel column stiffening plate 323 can form a mesh structure around the steel pipe 321, the bending resistance and bearing capacity of the steel pipe column 320 can be enhanced. At the same time, the spacing between the outer ring plates 322 can be set according to the cross-sectional size of the steel beam module 100 to form a connection end 324 that matches the cross-sectional size of the steel beam module 100.

[0064] refer to Figure 6 , wherein the steel beam module 100 includes a plurality of longitudinal beams 110, a plurality of transverse beams 120, a plurality of cantilever beams 130 and a plurality of edge beams 140, and the edge beams 140 are used to seal the edges of the entire structure. In some embodiments, when the overall structure is a rectangle with four sides, there are four edge beams 140. The plurality of longitudinal beams 110 and the plurality of transverse beams 120 are staggered and connected; two edge beams 140 are respectively arranged on the outside of the two outermost longitudinal beams 110 and the two edge beams 140 are arranged in parallel, the cantilever beam 130 is arranged in the extension direction of the transverse beam 120, one end of the cantilever beam 130 is connected to the longitudinal beam 110, and the other end is connected to the edge beam 140. The longitudinal beam 110 includes an H-shaped steel longitudinal beam 111 and a box beam 112. In the extension direction of the longitudinal beam 110, two adjacent steel pipe columns 320 are connected by the H-shaped steel longitudinal beam 111 or the box beam 112. The cross beam 120 includes an H-shaped steel cross beam 121 and an H-shaped steel secondary beam 122. In the extension direction of the cross beam 120, the H-shaped steel cross beam 121 connects two adjacent steel pipe columns 320, and H-shaped steel secondary beams 122 are arranged parallel and at intervals between adjacent H-shaped steel cross beams 121, and the two ends of the H-shaped steel secondary beam 122 are respectively connected to the two adjacent longitudinal beams 110.

[0065] Specifically, in the selection of the longitudinal beam 110, when the span between two adjacent steel pipe columns 320 in the extension direction of the longitudinal beam 110 is large, the box beam 112 is preferred; when the span between two adjacent steel pipe columns 320 in the extension direction of the longitudinal beam 110 is small, the H-shaped steel longitudinal beam 111 is preferred. This is because the box beam 112 has better torsion resistance in a large-span structure, and the H-shaped steel longitudinal beam 111 has a lighter deadweight for a small-span structure, which can reduce manufacturing costs and deadweight. The specific selection also needs to consider factors such as calculated loads.

[0066] like Figures 6 to 12As shown, the cantilever beam 130 is welded to the edge beam 140; the H-shaped steel longitudinal beam 111 includes a short beam 111a and a steel beam stiffening plate 111b, the short beam 111a is welded to the beam body of the H-shaped steel longitudinal beam 111, the steel beam stiffening plate 111b is connected to the short beam 111a, and is welded to the H-shaped steel longitudinal beam 111; the steel beam module 100 also includes a plurality of first connecting plates 150 and a plurality of second connecting plates 160, the short beam 111a and the H-shaped steel secondary beam 122 are both provided with bolt holes, the first connecting plate 150 is provided with a first bolt hole 151 corresponding to the bolt hole, and the bolt passes through the first bolt hole 151 and is threaded The first bolt hole 151 is connected to fix the first connecting plate 150, the short beam 111a and the H-shaped steel secondary beam 122, and the beam ends of the short beam 111a and the H-shaped steel secondary beam 122 are welded; bolt holes are provided on both sides of one end where the H-shaped steel longitudinal beam 111 and the steel pipe column 320 are connected, and the second connecting plate 160 is provided with a second bolt hole 161 corresponding to the bolt hole, and the bolt passes through the second bolt hole 161 and is threadedly connected to the second bolt hole 161 to fix the second connecting plate 160, the H-shaped steel longitudinal beam 111 and the steel pipe column 320, and the connecting end 324 of the H-shaped steel longitudinal beam 111 and the steel pipe column 320 is welded.

[0067] The cantilever beam 130 is connected to the edge beam 140 by welding; however, for the connection between the longitudinal beam 110 and the cross beam 120 that needs to bear more load, bolt welding is used. Specifically, a short beam 111a is welded on the beam body of the H-steel longitudinal beam 111, and the steel beam stiffening plate 111b is connected to the short beam 111a and welded to the H-steel longitudinal beam 111. Because the cross section of the cross beam 120 is smaller than the cross section of the H-steel longitudinal beam 111, the short beam 111a can be easily connected to the H-steel longitudinal beam 111. A first bolt hole 151 is provided on the first connecting plate 150, and the short beam 111a and the H-steel secondary beam 122 are connected through the first connecting plate 150 and connected by high-strength bolts. At the same time, the beam ends of the short beam 111a and the H-steel secondary beam 122 are welded and connected, and the short beam 111a and the web connection of the H-steel secondary beam 122 are welded to improve the shear resistance of the short beam 111a and the H-steel secondary beam 122, and further strengthen the connection effect. Similarly, since the box beam 112 is also a type of longitudinal beam 110, the short beam 111a can also be welded at the beam body of the box beam 112, and mixed with the H-steel secondary beam 122 in the same way. However, it should be noted that since the cross-sections of the box beam 112 and the H-steel longitudinal beam 111 are different, the applicable short beams 111a are also different. Specifically, the short beam 111a welded at the beam body of the box beam 112 is a variable cross-section short beam, and the short beam 111a welded on the beam body of the H-steel longitudinal beam 111 is an I-beam short beam.

[0068] In addition, the second connecting plate 160 is provided with a second bolt hole 161. Since the cross-sectional area of ​​the H-shaped steel longitudinal beam 111 and the steel pipe column 320 is large, it is not possible to achieve a good effect if only the second connecting plate 160 is used for connection. Therefore, the two sides of the connection end 324 of the H-shaped steel longitudinal beam 111 and the steel pipe column 320 are connected by high-strength bolts through the second connecting plate 160. At the same time, the connection end 324 of the H-shaped steel longitudinal beam 111 and the steel pipe column 320 is welded. The construction method of bolting and welding can not only meet the convenience of on-site bolt connection, but also increase the welding connection method, which can further consolidate the connection effect and improve the strength of the beam and column at the node.

[0069] It should be noted that the second connecting plate 160 includes three sizes, which are respectively used for connecting the H-shaped steel longitudinal beam 111, the box beam 112 and the H-shaped steel cross beam 121. Since the cross-sectional areas of the H-shaped steel longitudinal beam 111, the box beam 112 and the H-shaped steel cross beam 121 are different, the corresponding sizes of the second connecting plate 160 and the number of the second bolt holes 161 on the second connecting plate 160 are different. Generally, the larger the cross-sectional area of ​​the corresponding required connecting beam, the larger the size of the selected second connecting plate 160, and the more the number of the second bolt holes 161 on the corresponding second connecting plate 160.

[0070] In some embodiments, reference Figures 13 to 16 , a wet joint 211b is set between multiple precast panels 211, a stud 170 is set on the steel beam module 100 at the wet joint 211b, the steel truss 211a in the precast panel 211 extends out of the precast panel 211, and the stud 170 is arranged alternately with the steel truss 211a of the precast panel 211; a wet joint 211b is set between multiple precast panels 211, and multiple embedded longitudinal bars are set along the extension direction of the wet joint 211b. The panel module 200 includes a post-cast strip 220, which is set in the wet joint 211b, and the post-cast strip 220 uses non-shrinkage concrete. The surface steel bar 230 is laid on the cast-in-place layer 212 and the post-cast strip 220, and a slope layer 231 is set on the surface steel bar 230, and the surface steel bar 230 is buried in the slope layer 231.

[0071] By setting wet joints 211b between multiple precast panels 211, the overall area of ​​the panel module 200 can be divided into multiple panels, each of which corresponds to a precast panel 211. The size of the precast panel 211 can be selected according to the actual working conditions, so as to facilitate prefabrication in the factory in advance. The bolts 170 are set on the steel beam module 100 at the wet joints 211b, which can play a role in limiting the precast panel 211, preventing the laid precast panel 211 from moving, and improving the connection performance between the panel module 200 and the steel beam module 100. The bolts 170 are arranged alternately with the steel trusses 211a of the precast panels 211, and the steel trusses 211a in the precast panels 211 extend out of the precast panels 211. When concrete is poured in the wet joints 211b to form the post-cast strips 220, the post-cast strips 220 and the steel trusses 211a extending out of the precast panels 211 are engaged with each other to form a more compact whole, which can enhance the integrity and strength of the panel module. At the same time, multiple embedded longitudinal bars are arranged along the extension direction of the wet joint 211b, which can enhance the bending strength of the wet joint. The cast-in-place layer 212 is formed by pouring concrete on the precast panel 211 on site, and the cast-in-place layer 212, the precast panel 211, and the post-cast strip 220 form a whole. However, since the three are actually composed of different structures, the surface steel bars 230 are laid on the cast-in-place layer 212 and the post-cast strip 220, and low-grade concrete is poured on the surface steel bars 230 to form a slope layer 231.
