Description

Technical Field

[0001] This invention relates to the field of building materials, and in particular to a polygonal mesh cross-section steel floor slab. Background Technology

[0002] Currently, most prefabricated buildings use prefabricated components for assembly construction, which solves and avoids many of the difficulties faced by traditional construction sites.

[0003] However, the development and application of steel structure floor slabs in prefabricated building materials are currently lagging behind and insufficient. Steel structure panels are commonly used as roof panels, wall panels, and floor panels. Although steel structure panels are used in cladding components such as profiled sheets, sandwich panels, composite panels, and corrugated sheets, there are still unresolved issues regarding energy conservation, environmental protection, and fire resistance. The insufficient strength and sound and heat insulation problems of steel structure panels mean that reinforced concrete is mostly used as floor slabs in steel structure buildings.

[0004] Therefore, how to develop a steel structure building floor slab that is easy to process has become a technical problem that the industry urgently needs to solve. Summary of the Invention

[0005] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention aims to provide a solution to the difficulties in processing existing steel structure floor slabs.

[0006] Technical Solution: To achieve the above objectives, the polygonal mesh cross-section steel floor slab of the present invention is applied in the field of building materials. The technical solution includes:

[0007] A hollow structure profiled steel sheet is stacked in at least one layer along the vertical direction. The hollow structure profiled steel sheet includes a steel base plate and a structure with polygonal cross-section rib groove cavities arranged along the length of the base plate. Each structure is formed by bending the base plate.

[0008] A skin-like shell structure surrounding plate is provided to surround the at least one layer of hollow structural profiled steel sheet.

[0009] Furthermore, a first gap is provided between each adjacent structure. When the skin shell structure surrounds the hollow structure profiled steel sheet and is compressed, the first gap becomes smaller until the adjacent structures are at least partially pressed together, and a closed first cavity is formed above and / or below the pressed part.

[0010] Furthermore, a second gap consisting of a substrate is provided above the structure. When the skin-encased shell structure surrounds the hollow profiled steel sheet and is compressed, the second gap decreases until the adjacent substrates are pressed together, and the rib groove cavities form their own closed states.

[0011] Furthermore, there are at least two hollow profiled steel sheets that are fixedly connected in sequence along the horizontal direction, and the skin hoop structure surrounding plate is arranged to surround the at least two hollow profiled steel sheets.

[0012] Furthermore, the structure includes at least a first structure and a second structure stacked in a vertical direction. The first structure and the second structure are formed by bending a substrate and forming a first rib groove cavity and a second rib groove cavity respectively in the first structure and the second structure. The first rib groove cavity and the second rib groove cavity are connected to each other through the second gap.

[0013] Furthermore, the hollow profiled steel sheet is stacked in at least two layers along the vertical direction, and the skin hoop structure surrounding plate is arranged to surround the at least two layers of hollow profiled steel sheet.

[0014] Furthermore, the top of the structure is provided with a pointed tip, and a groove is formed between the pointed tips of each adjacent structure. The hollow structural profiled steel sheets of each adjacent layer are arranged opposite to each other, and the pointed tip of each layer of hollow structural profiled steel sheet is inserted into the groove of the oppositely arranged hollow structural profiled steel sheet.

[0015] Furthermore, the cross-sections of the first rib groove cavity and the second rib groove cavity are rhomboid or regular hexagonal, and the tips of the rhomboid or regular hexagonal shapes of the first rib groove cavity and the second rib groove cavity are oriented in the vertical direction.

[0016] Furthermore, the cross-sections of the first rib groove cavity and the second rib groove cavity are rectangular.

[0017] Furthermore, the structure also includes a third structure formed by bending the same substrate, and a third rib groove cavity is formed in the third structure. The third rib groove cavity and the second rib groove cavity are connected by a second gap.

[0018] Furthermore, the sides of the skin structure surrounding panel are prefabricated with splicing tenons, which are used to splice and install the polygonal mesh section steel floor slabs together through the splicing tenons.

[0019] Furthermore, the upper and / or lower surfaces of the skin structure surrounding panel are covered with decorative panels, which are made of one or more of glass, aluminum, stainless steel, wood, plastic, stone and ceramic.

[0020] Beneficial effects: The polygonal mesh cross-section steel floor slab of the present invention obtains superior cross-sectional properties by repeatedly bending the steel substrate to form a hollow structure profiled steel sheet. It not only ensures the strength of the floor slab and provides superior load-bearing capacity, but also blocks air convection with its internally formed closed mesh cross-section hollow structure, achieving the requirements of sound insulation, heat insulation and fire protection. It can replace concrete floor slabs, concrete wall panels and roof panels, is more green and environmentally friendly, and is lightweight, making it more suitable for prefabricated installation.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0031] Example 1:

[0032] See Figures 1 to 3 The embodiment 1 of the polygonal mesh cross-section steel floor slab of the present invention shown includes: at least one layer of hollow structural profiled steel sheet 110 stacked in the vertical direction, the hollow structural profiled steel sheet 110 including a steel base plate 101 and structural bodies 102 with polygonal cross-sections arranged along the length direction of the base plate 101, each of the structural bodies 102 being formed by bending the base plate 101; and a skin hoop structure surrounding plate 120 provided to surround the at least one layer of hollow structural profiled steel sheet 110.

[0033] By repeatedly bending steel substrates to form hollow profiled steel sheets, superior cross-sectional properties are achieved. This not only ensures the strength of the floor slab and provides excellent load-bearing capacity, but also blocks air convection with its internally formed closed mesh cross-section hollow structure, achieving the requirements of sound insulation, heat insulation and fireproofing. It can replace concrete floor slabs, concrete wall panels and roof panels, is more green and environmentally friendly, and is lightweight, making it more suitable for prefabricated installation.

[0034] In this embodiment, there are two hollow profiled steel sheets 110, which are fixedly connected sequentially along the horizontal direction, and the skin-like shell structure surrounding plate 120 is arranged to surround the two hollow profiled steel sheets 110. In other embodiments, the hollow profiled steel sheets 110 may also be arranged as one, three, or more along the horizontal direction, and such structural changes still fall within the protection scope of this invention.

[0035] Specifically, a second gap 1026, formed by a base plate 101, is provided above the structure 102. When the skin-like shell structure surrounding plate 120 surrounds the hollow profiled steel sheet and is under pressure, the second gap 1026 decreases until adjacent base plates 101 are pressed together, and the rib groove cavities form their own closed states. In this way, the vertical pressure-bearing capacity of the hollow profiled steel sheet 110 under pressure is increased, the vertical pressure is converted into horizontal stress, and the horizontal elastic deformation of the hollow profiled steel sheet relieves the vertical pressure.

[0036] The structure 102 includes a first structure 1021 and a second structure 1022 stacked vertically. The first structure 1021 and the second structure 1022 are formed by bending a single substrate 101 and respectively forming a first rib groove cavity 1023 and a second rib groove cavity 1024 within the first structure 1021 and the second structure 1022. The first rib groove cavity 1023 and the second rib groove cavity 1024 are connected by a second gap 1026. By increasing the number of structures, the load-bearing capacity in the vertical direction is improved.

[0037] Specifically, a first gap 1028 is provided between each adjacent first structure 1021, and a first gap 1028 is also provided between each adjacent second structure 1022. When the skin-like shell structure surrounding plate 120 surrounds the hollow structure profiled steel plate 110 and is subjected to pressure, the first gap 1028 decreases until the adjacent structures 102 are at least partially pressed together, forming a closed first cavity 1027 above and below the pressed portion. In this way, not only is the pressure in the vertical direction relieved by the elastic deformation of the structure 102, but the mutual pressing between the adjacent structures 102 further ensures the bearing capacity in the vertical direction.

[0038] The hollow profiled steel sheet 110 is arranged in four layers stacked vertically, with adjacent hollow profiled steel sheets 110 arranged in a mirror image. The skin-like shell structure surrounding plate 120 surrounds the four layers of hollow profiled steel sheets 110. By arranging the hollow profiled steel sheet 110 in four layers stacked vertically, the hollow profiled steel sheet 110 becomes more convenient for modular processing and assembly.

[0039] As a further optimization of this embodiment, the top of the structure 102 is provided with a tip, and a groove is formed between the tips of each adjacent structure 102. The hollow structural profiled steel plates of each adjacent layer are arranged opposite to each other, and the tip of each layer of hollow structural profiled steel plate is inserted into the groove of the oppositely arranged hollow structural profiled steel plate.

[0040] Specifically, the first rib groove cavity 1023 and the second rib groove cavity 1024 have a rhomboid cross-section, and the rhomboid shape of the first rib groove cavity 1023 and the second rib groove cavity 1024 is oriented vertically. In this way, the groove formed by the edges of the rhomboid fits with the apex of the rhomboid, which improves the assembly efficiency and allows the edges to be used for support.

[0041] As a further optimization of this embodiment, the side of the skin structure enclosure plate 120 is prefabricated with splicing tenons (not shown in the figure) to allow the polygonal mesh cross-section steel floor slabs to be spliced ​​and installed together through the splicing tenons, so as to facilitate the rapid splicing and installation of the polygonal mesh cross-section steel floor slabs on the construction site.

[0042] Preferably, the upper and lower surfaces of the skin structure enclosure panel 120 are covered with decorative panels, which are made of one or more of glass, aluminum plate, stainless steel plate, wood plate, plastic plate, stone plate and ceramic plate.

[0043] Example 2:

[0044] See Figure 4 and 5 As shown, in this embodiment, unlike the previous embodiment, the hollow profiled steel sheet 210 is a single layer along the vertical direction, and the cross-section of the rib cavity 203 inside the structure 202 is rectangular. A skin-like shell structure surrounding plate 220 surrounds this single layer of hollow profiled steel sheet 210. The rectangular cross-section ensures that each structure has two vertical steel plates, further providing load-bearing capacity in the vertical direction.

[0045] When the skin-like shell structure surrounds the hollow profiled steel sheet and is subjected to pressure, the first gap 206 between adjacent rib slot cavities decreases until adjacent structural members 202 are at least partially pressed together to improve stability and increase load-bearing capacity. Furthermore, the second gap 204 also decreases accordingly, causing the two substrates to approach each other until they are pressed together to provide load-bearing capacity.

[0046] Example 3

[0047] See Figures 6 to 8 As shown, in this embodiment, unlike Embodiment 1, the first rib groove cavity 3021 and the second rib groove cavity cross-section 3022 are regular hexagons. The structure 302 also includes a third structure 3023 formed by bending the same substrate 301. Correspondingly, a third rib groove cavity 3033 is formed in the third structure 3023. The third rib groove cavity 3033 and the second rib groove cavity 3032 are connected by a second gap 303. The cross-section of the third rib groove cavity 3033 is also regular hexagonal.

[0048] The hollow profiled steel sheet 310 has a two-layer structure along the vertical direction, with the structural bodies 302 arranged opposite each other. A skin-shell structure surrounding plate 320 surrounds the two layers of the hollow profiled steel sheet 310. When the skin-shell structure surrounding plate 320 surrounds the hollow profiled steel sheet and is subjected to pressure, the first gap 306 between adjacent hexagonal rib groove cavities decreases until adjacent structural bodies 302 are completely pressed together. Closed first cavities 304 and 305 are formed above and below the pressed portion between the steel sheet and the skin-shell structure surrounding plate 320, improving stability and increasing load-bearing capacity. Furthermore, the three-layer structure further enhances the load-bearing capacity in the vertical direction.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
