Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a steel floor slab with an arc-shaped mesh cross-section. Background Art

[0002] At present, prefabricated buildings mostly use prefabricated parts for assembly construction, which solves and avoids many difficulties faced by current traditional construction sites. However, the development and application of steel structure floor slabs in prefabricated building materials are obviously backward and insufficient. Steel structure plates are usually used as roof panels, wall panels, and floor panels. Although steel structure plates are used in enclosure panels such as corrugated panels, sandwich panels, composite panels, and tile rib panels, there are still problems to be solved in terms of energy saving, environmental protection, and fire prevention. Due to the lack of strength and sound insulation and heat insulation problems of steel structure plates, most floor panels of steel structure buildings use reinforced concrete as floor slabs. Therefore, how to propose a steel structure building floor slab that can be easily processed has become a technical problem that the industry urgently needs to solve. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention aims to provide a solution to the difficulties in processing existing steel structure floor slabs.

[0004] Technical solution: To achieve the above-mentioned purpose, the arc-shaped mesh-section steel floor slab of the present invention is applied to the field of building materials. The technical solution includes: hollow structural corrugated steel plates stacked in at least one layer along the vertical direction, the hollow structural corrugated steel plates including a steel base plate and a structure arranged along the length direction of the base plate and having a cross-section including at least one arc-shaped rib groove cavity, each of the structures being formed by bending the base plate; a skin hoop shell structure enclosing plate arranged to enclose the at least one layer of hollow structural corrugated steel plates.

[0005] Furthermore, the structure includes two arc substrates formed by bending a substrate and arranged opposite to each other.

[0006] Furthermore, a first gap is provided between each adjacent structure. When the skin hoop structure surrounding plate surrounds the hollow structural corrugated steel plate 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.

[0007] Furthermore, a second gap formed by a base plate is provided above the structure. When the skin hoop structure surrounding plate surrounds the hollow structural corrugated steel plate and is compressed, the second gap becomes smaller until the adjacent base plates are pressed against each other, and the rib groove cavities form their own closed state.

[0008] Furthermore, there are at least two hollow structural corrugated steel plates which are fixedly connected in sequence along the horizontal direction, and the skin hoop shell structure surrounding plate is arranged to surround the at least two hollow structural corrugated steel plates.

[0009] 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 arranged in the first structure and the second structure, and the first rib groove cavity and the second rib groove cavity are connected through the second gap.

[0010] Furthermore, the hollow structural corrugated steel plates are stacked in at least two layers along the vertical direction, and the skin hoop shell structure surrounding plates are arranged to surround the at least two layers of hollow structural corrugated steel plates.

[0011] Furthermore, a tip is provided at the top of the second structure, and a groove is formed between the tips of adjacent second structures. The adjacent layers of hollow structural corrugated steel plates are arranged relative to each other, and the tip of each layer of hollow structural corrugated steel plates is inserted into the groove of the relatively arranged hollow structural corrugated steel plates.

[0012] Furthermore, the structure also includes a third structure formed by bending the same substrate. Correspondingly, a third rib groove cavity is formed in the third structure, and the third rib groove cavity is connected to the second rib groove cavity via a second gap.

[0013] Furthermore, the side surfaces of the skin structure enclosure panels are prefabricated with joints for connecting and installing the arc-shaped mesh-section steel floor panels. Furthermore, the upper and / or lower surfaces of the skin structure enclosure panels are paved with decorative panels, which are made of one or more of glass, aluminum, stainless steel, wood, plastic, stone, and ceramic.

[0014] Beneficial effects:

[0015] The arc-shaped mesh cross-section steel floor slab of the present invention is formed by bending the steel base plate multiple times into a hollow structural corrugated steel plate with an arc-shaped cross-section, and utilizing the elastic effect of the arc-shaped steel plate to obtain excellent cross-sectional characteristics. It not only ensures the strength of the floor slab and provides excellent load-bearing capacity, but also uses the closed mesh cross-section hollow structure formed inside to block air convection and meet the requirements of sound insulation, heat insulation and fire prevention. It can replace concrete floor slabs, concrete wall panels and roof panels, is more green and environmentally friendly, and is lightweight and more suitable for prefabricated installation.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] It should be noted that the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0021] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] See also Figures 1 to 3 The embodiment 1 of the circular arc mesh section steel floor slab of the present invention shown includes: hollow structural corrugated steel plates 10 stacked in at least one layer along the vertical direction, the hollow structural corrugated steel plates 10 including a steel base plate 1 and a structure 2 arranged along the length direction of the base plate 1 and having a cross-section including at least one circular arc rib groove cavity, each of the structures 2 being formed by bending the base plate 1; and a skin hoop shell structure enclosing plate 3 provided to enclose the at least one layer of hollow structural corrugated steel plates 10.

[0023] By bending the steel base plate 1 multiple times to form a hollow structural corrugated steel plate 10, the elastic effect of the arc-shaped steel plate is utilized to obtain excellent cross-sectional characteristics, which not only ensures the strength of the floor slab and provides excellent load-bearing capacity, but also uses the closed mesh cross-sectional hollow structure formed inside to block air convection and meet the requirements of sound insulation, heat insulation and fire prevention. It can replace concrete floor slabs, concrete wall panels and roof panels, is more green and environmentally friendly, and is lightweight and more suitable for prefabricated installation.

[0024] In this embodiment, the structure 2 comprises two opposing arc-shaped substrates formed by bending the substrate 1. When subjected to pressure, the two opposing arc-shaped substrates expand outward, forming elastic deformation, thereby alleviating vertical pressure through elastic force, thereby exponentially increasing the load-bearing capacity.

[0025] Specifically, a first gap 26 is defined between adjacent structures 2. When the skin hoop shell structure enclosing plate 3 surrounds the hollow structural corrugated steel sheet 10 and is subjected to pressure, the first gap 26 decreases until the adjacent structures 2 are at least partially in contact with each other, forming a closed first cavity above and / or below the contacted portion. When the structures 2 are in contact, vertical pressure can be transferred horizontally, thereby improving the vertical load-bearing capacity.

[0026] A second gap 25 formed by the base plate 1 is provided above the structure 2. When the skin hoop shell structure enclosing plate 3 surrounds the hollow structural corrugated steel sheet 10 and is compressed, the second gap 25 decreases until adjacent base plates 1 abut against each other, and the rib groove cavities are each closed. Under pressure, the closed rib groove cavities expand outward to form a nearly circular shape, which is the optimal load-bearing shape, further improving the load-bearing effect.

[0027] In this embodiment, the hollow structural corrugated steel plate 10 is set as one in the horizontal direction. In other embodiments, the hollow structural corrugated steel plate 10 can be set as two, three or even more in the horizontal direction, and fixed in sequence by bolts or welding, snapping, etc. The skin hoop shell structure enclosing plate 3 is set to surround multiple hollow structural corrugated steel plates 10. Such structural changes still fall within the scope of protection of the present invention.

[0028] In this embodiment, the structure 2 includes a first structure 21 and a second structure 22 stacked in a vertical direction. The first structure 21 and the second structure 22 are formed by bending a substrate 1 and respectively forming a first rib groove cavity 23 and a second rib groove cavity 24 arranged in the first structure 21 and the second structure 22. The first rib groove cavity 23 and the second rib groove cavity 24 are connected by the second gap 25.

[0029] A plurality of structures 2 are provided in the vertical direction, thereby further improving the bearing capacity in the vertical direction.

[0030] In this embodiment, the hollow structural corrugated steel plates 10 are stacked in two layers along the vertical direction, and the skin hoop shell structure surrounding plates 3 are arranged to surround the two layers of hollow structural corrugated steel plates 10 .

[0031] The hollow structural corrugated steel plates 10 may also be arranged in three, four or more layers along the vertical direction, with each adjacent hollow structural corrugated steel plate 10 arranged in a mirror image. Such structural changes still fall within the scope of protection of the present invention.

[0032] As a further optimization of this embodiment, a tip is provided at the top of the second structure 22, and a groove is formed between the tips of each adjacent second structure 22. The adjacent layers of the hollow structural corrugated steel plates 10 are arranged relative to each other, and the tip of each layer of the hollow structural corrugated steel plates 10 is inserted into the groove of the relatively arranged hollow structural corrugated steel plates 10.

[0033] To achieve faster on-site assembly and improve assembly efficiency. As a further optimization of this embodiment, the structure 2 also includes a third structure formed by bending the same substrate 1. Correspondingly, a third rib groove cavity is formed in the third structure 2. The third rib groove cavity and the second rib groove cavity 24 are connected by a second gap 25. In other embodiments, more layers of stacked structures 2 may also be provided, and such structural changes still fall within the scope of protection of the present invention.

[0034] As a further optimization of this embodiment, the side surfaces of the skin structure surrounding panels are prefabricated with splicing mortises (not shown in the figure) so as to enable the arc-shaped mesh-section steel floor panels to be spliced ​​and installed through the splicing mortise and tenon.

[0035] To improve on-site construction and assembly efficiency. As a further optimization of this embodiment, the upper and / or lower surfaces of the skin structure surrounding the plate are paved with decorative panels (not shown), and the panels are made of one or more of glass, aluminum, stainless steel, wood, plastic, stone, and ceramic.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
