Example 1:
referring to fig. 1 to 3, an embodiment 1 of the steel floor slab with a polygonal net-shaped section according to the present invention includes: the profiled steel sheet 110 is at least one layer of hollow-structure profiled steel sheet stacked in the vertical direction, the profiled steel sheet 110 comprises a steel base plate 101 and structural bodies 102 which are arranged along the length direction of the base plate 101 and have rib groove cavities with polygonal cross sections, and each structural body 102 is formed by bending the base plate 101; a skin hoop shell structure enclosing plate 120 is provided to enclose the at least one layer of hollow structural profiled steel sheets 110.
The steel substrate is bent for multiple times to form the hollow profiled steel sheet, so that the superior section characteristic is obtained, the strength of the floor slab is guaranteed, the superior bearing capacity is provided, the requirements of sound insulation, heat insulation and fire prevention are met by respectively forming the closed net-shaped section hollow lattice inside the steel substrate and blocking air convection, the steel substrate can replace a concrete floor slab, a concrete wallboard and a roof panel, and the steel substrate is more environment-friendly, light in weight and more suitable for assembly type installation.
In this embodiment, the two hollow profiled steel sheets 110 are sequentially and fixedly connected along the horizontal direction, and the covering hoop-shell structure enclosing plate 120 is disposed to enclose the two hollow profiled steel sheets 110. In other embodiments, the hollow profiled steel sheets 110 may be arranged in one, three or more horizontal directions, and such structural changes still fall within the scope of the present invention.
Specifically, a second gap 1026 formed by the base plate 101 is provided above the structural body 102, and when the skin hoop shell structure enveloping plate 120 surrounds and presses the hollow structural profiled steel sheet, the second gap 1026 becomes smaller until the adjacent base plates 101 are attached to each other, and the rib groove cavities form respective closed states. Thus, the vertical pressure-bearing capacity of the hollow-structure profiled steel sheet 110 in a pressed state is increased, the vertical pressure is converted into the horizontal stress, and the vertical pressure is relieved through the horizontal elastic deformation of the hollow-structure profiled steel sheet.
The structural body 102 comprises a first structural body 1021 and a second structural body 1022 which are stacked in the vertical direction, the first structural body 1021 and the second structural body 1022 are formed by bending a substrate 101, and form a first rib-groove cavity 1023 and a second rib-groove cavity 1024 which are respectively arranged in the first structural body 1021 and the second structural body 1022, and the first rib-groove cavity 1023 and the second rib-groove cavity 1024 are communicated through the second gap 1026. By increasing the number of the structures, the pressure-bearing capacity in the vertical direction is improved.
Specifically, a first gap 1028 is provided between each adjacent first structure 1021 and a first gap 1028 is provided between each adjacent second structure 1022, and when the skin hoop and shell structure enveloping plate 120 surrounds and compresses the hollow profiled steel sheet 110, the first gap 1028 is reduced until at least partially abutting between the adjacent structures 102 and forming a closed first cavity 1027 above and below the abutting portion. Therefore, the pressure in the vertical direction is relieved through the elastic deformation of the structural bodies 102, and the pressure bearing capacity in the vertical direction is further ensured through the mutual close adhesion between the adjacent structural bodies 102.
Hollow structure profiled steel sheet 110 is four layers along vertical direction and piles up the setting, and two adjacent hollow structure profiled steel sheets 110 are the relative setting of mirror image, covering hoop shell structure enclosing plate 120 is and surrounds four layers of hollow structure profiled steel sheet 110 sets up. By stacking the hollow-structure profiled steel sheet 110 in four layers in the vertical direction, the hollow-structure profiled steel sheet 110 becomes more convenient for modular processing and assembly.
As a further optimization of this embodiment, the top end of the structural body 102 is provided with a tip, a groove is formed between the tips of the structural bodies 102, the hollow profiled steel sheets of adjacent layers are oppositely arranged, and the tip of each layer of the hollow profiled steel sheet is inserted into the groove of the hollow profiled steel sheet oppositely arranged.
Specifically, the first rib-groove cavity 1023 and the second rib-groove cavity 1024 are rhombic, and the rhombuses of the first rib-groove cavity 1023 and the second rib-groove cavity 1024 are arranged in the vertical direction. Therefore, the groove formed by the diamond-shaped edge is matched with the diamond-shaped vertex angle, the assembly efficiency is improved, and the edge can be used for supporting.
As a further optimization of this embodiment, a splicing rabbet (not shown) is prefabricated on a side surface of the skin structure enclosing plate 120, so that each steel floor slab with polygonal net-shaped cross section is spliced and installed through the splicing rabbet, and the steel floor slabs with polygonal net-shaped cross section can be spliced and installed quickly at a construction site.
Preferably, the upper and lower surfaces of the skin structure enclosing plate 120 are attached with decorative panels, and the panels are made of one or more of glass, aluminum plate, stainless steel plate, wood plate, plastic plate, stone plate and ceramic plate.
Example 2:
referring to fig. 4 and 5, in the present embodiment, unlike the previous embodiment, a hollow structural profiled steel sheet 210 has a one-layer structure in the vertical direction, and a rib groove cavity 203 in a structural body 202 has a rectangular cross section. A skin hoop shell structure enclosing plate 220 is disposed around the layer of hollow structural profiled steel sheets 210. The rectangular cross section enables each structure to have two vertical steel plates, further providing load bearing capacity in the vertical direction.
When the skin hoop shell structure surrounding plate surrounds the hollow profiled steel sheet and is compressed, the first gap 206 between adjacent rib groove cavities becomes smaller until adjacent structures 202 are at least partially attached to each other, so as to improve stability and increase pressure-bearing capacity. And the second gap 204 is correspondingly reduced so that the two substrates are close to each other until they are close to each other to provide load bearing capability.
Example 3
Referring to fig. 6 to 8, in the present embodiment, unlike embodiment 1, the first rib and groove cavity 3021 and the second rib and groove cavity section 3022 are regular hexagons. The structural body 302 further includes a third structural body 3023 formed by bending the same substrate 301, a third rib-groove cavity 3033 is correspondingly formed in the third structural body 3023, and the third rib-groove cavity 3033 and the second rib-groove cavity 3032 are communicated through a second gap 303.

The hollow structure profiled steel sheet 310 is a two-layer structure along the vertical direction, and the structure 302 is in relative setting, and the covering hoop shell structure surrounding plate 320 surrounds this two-layer hollow structure profiled steel sheet 310 setting. When the skin hoop shell structure enclosing plate 320 encloses the hollow profiled steel sheet and is pressed, the first gap 306 between the adjacent regular hexagonal rib groove cavities is reduced until the adjacent structural bodies 302 are completely attached, and closed first cavities 304 and 305 are formed between the upper part and the lower part of the attached part and the skin hoop shell structure enclosing plate 320, so that the stability is improved, and the pressure-bearing capacity is increased. And moreover, the bearing capacity in the vertical direction is further improved through the arrangement of the three layers of structural bodies.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the utility model and these are intended to be within the scope of the utility model.
