Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, in particular to a prefabricated steel structure floor. Background Art

[0002] The floor slab is a kind of load-bearing component, the load-bearing part in the floor slab layer, which divides the house into several layers in the vertical direction, and transmits the vertical loads such as people and furniture and the self-weight of the floor slab to the foundation through walls, beams or columns. With the continuous improvement of people's living standards, people's requirements for the construction speed, construction cost, construction quality, energy conservation and environmental protection of residential and other construction industries are also constantly increasing. In order to save resources and energy, reduce construction pollution, improve labor productivity and quality safety level, develop green buildings and advanced construction methods, prefabricated building materials are gradually entering the market. Prefabricated buildings have been a hot spot for research and development practice in various scientific research institutions and construction enterprises in recent years. Various prefabricated components are rich in forms and types. New, high-quality, and prefabricated component products with different performances have developed rapidly and are widely used. They can realize standardized design, factory-based or even productized production, assembly construction, integrated decoration, information management, and intelligent application, effectively improving construction efficiency, reducing costs, saving energy and resources, reducing construction waste and adverse effects on the environment, etc., improving technical level and engineering quality, and promoting the transformation and upgrading of the construction industry.

[0003] The Chinese patent with publication number CN117166661A discloses a steel structure and an assembled steel structure floor. The device uses a pull ring, a pull rod, a U-shaped pallet and other components in coordination. By pulling the pull ring, the pull rod and the U-shaped pallet rise inside the adjustment groove, so that the U-shaped pallet releases the lock on the T-shaped lock block, which facilitates the rapid disassembly of the steel truss, avoids the need for timely replacement of the steel truss due to external force impact or other damage during construction, and improves the convenience of disassembly of the steel truss.

[0004] However, in actual use of the above structure, due to the large number of slots in the main frame and the complexity of internal parts, the bearing strength of the main frame will be reduced, thus posing certain safety hazards.

[0005] The Chinese patent with publication number CN219080704U discloses an assembled steel structure floor, which connects adjacent floor slabs through connecting plates, and does not require reserved space for floor movement during assembly, which reduces the difficulty of installation and improves installation efficiency. In addition, the steel keel body, the top of the transverse steel bar support frame and the top of the connecting plate are set to the same plane to ensure the flatness of the floor slab after splicing.

[0006] However, the traditional floor slab is connected to the cross beam by screws. This connection method requires pre - reserved threaded holes on the cross beam, which not only reduces the strength of the cross beam, but also requires strict control over the precision of the threaded holes. Undoubtedly, it increases the labor intensity of workers and the installation difficulty of the floor slab. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the present invention provides a prefabricated steel structure floor slab, which solves the problems put forward in the background technology.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: A prefabricated steel structure floor slab includes a rigid frame and also includes a floor slab member. The floor slab member includes an assembled floor slab, and reinforcing steel pipes are evenly embedded in the assembled floor slab. Both ends of the reinforcing steel pipes penetrate through the assembled floor slab and are provided with insertion cavities; The floor slab member also includes a sound insulation layer disposed on the upper surface of the assembled floor slab and a lower - layer concrete disposed on the lower surface of the assembled floor slab. A heat - insulation layer is provided on the upper surface of the sound insulation layer, and an upper - layer concrete is provided on the upper surface of the heat - insulation layer; Both ends of the floor slab member are each installed with a first outer frame, a limiting frame is installed on the outside of the first outer frame, and rigid insertion columns are evenly provided on the limiting frame. The rigid insertion columns penetrate through the first outer frame and are inserted into the insertion cavities; Both ends of the other two ends of the floor slab member are each installed with a second outer frame, and limiting insertion holes are opened at both ends of the second outer frame. The limiting insertion holes are inserted and connected with both ends of the limiting frame.

[0009] Further, the rigid frame is composed of a support steel frame and columns. The support steel frame includes support steel profiles. There are two support steel profiles in total. The inner sides of the two support steel profiles are fixedly connected to both ends of the floor slab member, and cross beams are symmetrically installed between the two support steel profiles; The columns are disposed at the connection of the cross beam and the support steel profile, and a carrying step for lapping with the cross beam and the support steel profile is opened at the upper end of the column. A second reinforcing angle steel that abuts against the lower surface of the support steel profile is fixed on the outside of the column, and a first reinforcing angle steel that abuts against the lower surface of the cross beam is also fixed on the outside of the column.

[0010] Further, a second fastening bolt penetrating through the column is provided between the second reinforcing angle steel and the first reinforcing angle steel on the same column. A third fastening bolt is provided between the first reinforcing angle steel and the cross beam, and a fourth fastening bolt is provided between the second reinforcing angle steel and the support steel profile.

[0011] Further, the limiting frame is of a "U" - shaped structure, and a first fastening bolt is provided at the connection of the limiting frame and the limiting insertion hole.

[0012] Further, side plates are provided at the lower ends of the first outer frame and the second outer frame, and the side plates abut against the lower surface of the floor slab member.

[0013] Furthermore, the supporting steel is an "L"-shaped structure, and a gap between the supporting steel and the limiting frame forms a concrete pouring layer, in which concrete is poured for limiting the rigid plug column.

[0014] Furthermore, corrugated steel plates are installed in the gaps between the floor slabs and between the floor slabs and the cross beams, and both ends of the corrugated steel plates are respectively fixed on two supporting steel sections.

[0015] Furthermore, the sound insulation layer is a rectangular structure, and side sound insulation boards are provided on both sides of the sound insulation layer, and the side sound insulation boards extend to the gap between the second outer frame and the assembly floor.

[0016] Furthermore, the thermal insulation layer is a glass wool board, and the thermal insulation layer is connected to the sound insulation layer and the upper concrete layer by gluing.

[0017] Furthermore, ribs perpendicular to the reinforcing steel pipes are arranged at equal intervals inside the assembled floor slab, and the ribs are connected to the reinforcing steel pipes by bundling.

[0018] The present invention has the following beneficial effects:

[0019] (1) The prefabricated steel structure floor can protect the side of the floor by the first outer frame and the second outer frame, so as to extend the service life of the floor and facilitate the installation of the floor. By strengthening the connection between the insertion cavity on the steel pipe and the rigid insertion column, the first outer frame and the second outer frame are set to form an outer skeleton of the floor, which is conducive to the later installation of the floor. In addition, by plugging the limit frame with the limit insertion hole on the second outer frame, the limit frame and the floor can be connected, which is conducive to the extension of the outer edge of the floor, so as to facilitate the later installation of the floor. By plugging the rigid insertion column and the insertion cavity, the connection strength between the limit frame and the floor is improved, which is conducive to improving the stability of the floor after installation. By pouring concrete at the concrete pouring layer, the limit of the steel pipe is strengthened, which is conducive to the fixation of the floor, so as to facilitate the installation of the floor, avoid the use of bolts on a large scale to reduce the strength of the supporting steel, and facilitate the construction of workers.

[0020] (2) The prefabricated steel structure floor improves the thermal insulation effect of the floor components by setting a thermal insulation layer, improves the sound insulation effect of the floor components by setting a sound insulation layer, and improves the strength of the floor components by setting a reinforced steel pipe. The prefabricated floor 81 can be protected by setting an upper layer of concrete and a lower layer of concrete, thereby extending the service life of the prefabricated floor.

[0021] (3) The prefabricated steel structure floor can realize the rapid construction of the rigid frame through the arrangement of columns, supporting steel and beams, thereby reducing the construction difficulty and accelerating the project cycle. The mounting step at the upper end of the column is conducive to the mounting of the supporting steel. With the arrangement of the second reinforcing angle steel, the supporting steel is fixed and the supporting strength of the supporting steel is improved. With the arrangement of the first reinforcing angle steel, the beam is supported and fixed, thereby facilitating the improvement of the overall structural strength and stability of the rigid frame. In addition, with the arrangement of the second fastening bolts, the second reinforcing angle steel, the first reinforcing angle steel and the column are tightly connected, thereby improving the stability of the second reinforcing angle steel and the first reinforcing angle steel after installation.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0038] See also Figure 1 - Fig.12 The embodiment of the present invention provides a technical solution: an assembled steel structure floor, including a rigid frame and a floor member 8, wherein the floor member 8 includes an assembled floor 81, and reinforcing steel pipes 82 are evenly buried in the assembled floor 81. The bearing strength of the floor member 8 is improved by the arrangement of the reinforcing steel pipes 82. In addition, both ends of the reinforcing steel pipes 82 penetrate the assembled floor 81 and are provided with insertion cavities to facilitate the later installation of the floor member 8. Preferably, the outer diameter of the reinforcing steel pipe 82 is 1 / 2-2 / 3 of the thickness of the assembled floor 81, and the inner diameter of the insertion cavities at both ends of the reinforcing steel pipe 82 is 1 / 2 of the outer diameter of the reinforcing steel pipe 82.

[0039] In this embodiment, the interior of the reinforcing steel pipe 82 can be either a hollow structure or a solid structure. The hollow structure reduces the weight of the entire floor member 8, and the solid structure can improve the overall bearing capacity of the floor member 8. In order to improve the connection strength between the reinforcing steel pipe 82 and the assembled floor 81, a threaded groove can be opened on the surface of the reinforcing steel pipe 82 to increase the contact area between the assembled floor 81 and the reinforcing steel pipe 82, thereby improving the stability of the reinforcing steel pipe 82 after installation.

[0040] In addition, the floor slab 8 also includes a sound insulation layer 83 placed on the upper surface of the assembled floor slab 81 and a lower layer of concrete 86 arranged on the lower surface of the assembled floor slab 81. The upper surface of the sound insulation layer 83 is provided with an insulation layer 84, and the upper surface of the insulation layer 84 is provided with an upper layer of concrete 85. Through the arrangement of the upper layer of concrete 85 and the lower layer of concrete 86, the assembled floor slab 81 can be protected, thereby extending the service life of the assembled floor slab 81.

[0041] In this embodiment, the thermal insulation layer 84 can be a component made of glass wool or rock wool. The thermal insulation effect of the floor component 8 is improved by setting the thermal insulation layer 84. The sound insulation layer 83 is a porous plate structure to achieve a soundproofing effect. The sound insulation effect of the floor component 8 is improved by setting the sound insulation layer 83, thereby improving the practicability of the equipment.

[0042] To facilitate the installation of the floor slab member 8, a first outer frame 11 is installed at both ends of the floor slab member 8, and a limiting frame 10 is installed on the outer side of the first outer frame 11. Rigid columns 13 are evenly arranged on the limiting frame 10. The rigid columns 13 pass through the first outer frame 11 and are inserted into the insertion cavity. Preferably, the length of the insertion cavity is 1 / 4 of the reinforcing steel pipe 82 to improve the stability of the rigid columns 13 after installation. In addition, when the reinforcing steel pipe 82 is a hollow pipe, the rigid columns 13 can be inserted to 1 / 2 of the reinforcing steel pipe 82, thereby improving the structural strength of the reinforcing steel pipe 82; second outer frames 12 are installed at the other two ends of the floor slab member 8, and limiting holes 14 are provided at both ends of the second outer frame 12, and the limiting holes 14 are connected to the two ends of the limiting frame 10.

[0043] In this solution, it is preferred that the first outer frame 11 and the second outer frame 12 are both members of a rigid material, and the first outer frame 11 and the second outer frame 12 are tightly connected to the outer wall of the floor slab 8 to improve the strength of the floor slab 8, which is beneficial to the protection of the outer edge of the floor slab 8, so as to facilitate the transportation of the floor slab 8, avoid damage to the floor slab 8 during transportation, and improve the service life of the floor slab 8. In addition, the first outer frame 11 and the second outer frame 12 are provided to form an outer skeleton of the floor slab 8, which is beneficial to the later installation of the floor slab 8. In addition, the limit frame 10 By plugging into the limiting socket 14 on the second outer frame 12, the connection between the limiting frame 10 and the floor member 8 can be achieved, which is beneficial to the extension of the outer edge of the floor member 8, thereby facilitating the later loading of the floor member 8, so as to facilitate the later installation of the floor member 8, avoid excessive use of bolts and cause the structural strength of the supporting steel 3 to decrease, and can reduce the difficulty of operation for workers, facilitate the rapid installation of the floor member 8, and improve the connection strength between the limiting frame 10 and the floor member 8 through the plug-in between the rigid plug column 13 and the plug cavity, which is beneficial to improve the stability of the floor member 8 after installation.

[0044] It should be noted that bolts are usually used to connect the traditional floor slabs and steel frames for fixing the floor slabs during installation. However, this method inevitably requires the opening of reserved holes on the steel frame, which not only requires precise control of the accuracy of the reserved holes, but also reduces the strength of the steel frame, causing the structural performance of the steel frame to decline. Therefore, this solution changes the connection method between the floor slab member 8 and the supporting steel 3 and adopts a connection method combined with concrete to avoid opening installation holes on the supporting steel 3, thereby ensuring the structural strength of the supporting steel 3 and improving its bearing effect during support.

[0045] like Figure 1 - Figure 3 As shown, the rigid frame provided in this embodiment is composed of a supporting steel frame and a column 1. The supporting steel frame includes supporting steel sections 3. There are two supporting steel sections 3. The inner sides of the two supporting steel sections 3 are fixedly connected to the two ends of the floor slab member 8 for fixing the two ends of the floor slab member 8, and a crossbeam 2 is symmetrically installed between the two supporting steel sections 3. The crossbeam 2 is used to limit the edge of the plane floor. It is preferred that a cavity is provided inside the crossbeam 2 to reduce the weight of the crossbeam 2 without reducing the quality of the crossbeam 2, thereby helping to reduce the material consumption. In addition, the crossbeam 2 can also be made of I-beams. When I-beams are used, the edge of the floor slab member 8 can be placed on the inner side of the I-beam to improve the stability of the floor slab member 8 after installation.

[0046] The support rails 3 are provided with a plurality of support rails 1 and a plurality of support rails 2, and the plurality of support rails 3 are provided with plurality of support rails 1 and a plurality of support rails 2 are provided on the support rails 3.

[0047] In this embodiment, with the provision of the second reinforcing angle steel 5, the supporting steel 3 is fixed and the supporting strength of the supporting steel 3 is improved, and with the provision of the first reinforcing angle steel 4, the crossbeam 2 is supported and fixed, which is beneficial to improving the overall structural strength and stability of the rigid frame.

[0048] like Figure 1 - Figure 3As shown in the figure, to improve the stability of the first reinforcing angle steel 4 and the second reinforcing angle steel 5 after installation, a second fastening bolt passing through the column 1 is provided between the second reinforcing angle steel 5 and the first reinforcing angle steel 4 on the same column 1. Through the setting of the second fastening bolt, the second reinforcing angle steel 5, the first reinforcing angle steel 4 and the column 1 are tightly connected, thereby improving the stability of the second reinforcing angle steel 5 and the first reinforcing angle steel 4 after installation. It should be noted that anti-slip pads are installed on the outer sides of the second reinforcing angle steel 5 and the first reinforcing angle steel 4. The anti-slip pads are made of rigid materials to improve the stability of the second fastening bolt after installation. In addition, to fix the cross beam 2, a third fastening bolt is provided between the first reinforcing angle steel 4 and the cross beam 2 to facilitate the fixation of the cross beam 2 after installation. To fix the support section steel 3, a fourth fastening bolt is provided between the second reinforcing angle steel 5 and the support section steel 3 to facilitate the fixation of the support section steel 3 after installation.

[0049] As Fig. 9 - Fig.12 As shown in the figure, to realize the installation and fixation of the limit frame 10, the limit frame 10 provided in this embodiment has a "U" - shaped structure to facilitate the insertion of both ends of the limit frame 10 into the limit jack 14. And a first fastening bolt is provided at the connection between the limit frame 10 and the limit jack 14 for fixing the limit frame 10 after it is inserted into the limit jack 14. To increase the contact area between the limit jack 14 and the limit frame 10, the widths of both ends of the second outer frame 12 can be increased so that the limit jack 14 and the limit frame 10 are adapted. To improve the stability of the connection between the limit frame 10 and the limit jack 14, an anti - slip pad can also be installed at the connection between the limit frame 10 and the limit jack 14. The anti - slip pad is a rigid component to prevent the first fastening bolt from loosening and improve the stability of the first fastening bolt after installation.

[0050] As Fig.10 - Fig.12 As shown in the figure, to facilitate the fixation of the floor slab member 8, side plates are provided at the lower ends of both the first outer frame 11 and the second outer frame 12. The side plates are integrally formed with the first outer frame 11 and the second outer frame 12 by casting respectively, and the side plates are in contact with the lower surface of the floor slab member 8, thereby realizing the installation and placement of the floor slab member 8 and improving the stability of the floor slab member 8 after installation.

[0051] As Figure 5 and Figure 6 As shown in the figure, the support section steel 3 provided in this embodiment has an "L" - shaped structure to facilitate the loading of the floor slab member 8. And a concrete pouring layer 9 is formed in the gap between the support section steel 3 and the limit frame 10. Concrete is poured in the concrete pouring layer 9 for the limit of the rigid insertion column 13.

[0052] In this solution, it is preferred to provide a bearing plate on the supporting steel 3 that overlaps the rigid plug column 13. The bearing plate and the supporting steel 3 can be connected by welding, fixed by glue, or installed in a non-fixed manner, which facilitates the position adjustment of the bearing plate on the supporting steel 3 and is used for temporary fixing and limiting of the rigid plug column 13. After the concrete is poured in the later stage, the bearing plate and the rigid plug column 13 can be fixed.

[0053] In this embodiment, the width of the concrete pouring layer 9 is preferably not less than the width of the limit frame 10. By pouring concrete in the concrete pouring layer 9, the rigid columns 13 are fixed inside the concrete, thereby improving the stability of the rigid columns 13 after installation, and then improving the stability of the floor slab 8 after installation. Through the cooperation between the rigid columns 13 and the concrete, it is possible to avoid using bolts to fix the floor slab 8, thereby improving the fixing effect of the floor slab 8, facilitating the installation of the floor slab 8, avoiding the large-scale use of bolts to reduce the strength of the supporting steel 3, and facilitating construction by workers.

[0054] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in order to prevent the gap between two adjacent floor slabs 8 from affecting the floor effect, a corrugated steel plate 7 is installed at the gap between the floor slabs 8 and the floor slabs 8 and between the floor slabs 8 and the crossbeam 2. The two ends of the corrugated steel plate 7 are respectively fixed on two supporting steel profiles 3. Through the arrangement of the corrugated steel plate 7, it is possible to prevent the gap between two adjacent floor slabs 8 from affecting the floor effect. Optionally, rubber plates are provided on both sides of the corrugated steel plate 7. The rubber plates can be tightly connected to the floor slabs 8 by gluing to improve the waterproof effect between the two adjacent floor slabs 8.

[0055] In this embodiment, both ends of the corrugated steel plate 7 are preferably arranged inside the concrete pouring layer 9. The two ends of the corrugated steel plate 7 can be fixed to the supporting steel 3 by welding, and the fixing effect of the two ends of the corrugated steel plate 7 can be improved after concrete pouring. In addition, the corrugated steel plate 7 can be an inverted "T" structure, and its lower end is against the two adjacent second outer frames 12 to assist in bearing the mass of the second outer frames 12. In addition, the second outer frame 12 can be connected to the corrugated steel plate 7 by bolts to improve the overall performance of the second outer frame 12 and the corrugated steel plate 7, thereby improving the stability of the floor slab 8 after installation.

[0056] like Fig.12 As shown, the above-mentioned sound insulation layer 83 is a rectangular structure, which has completely covered the upper surface of the assembly floor 81, and side sound insulation boards are provided on both sides of the sound insulation layer 83, and the side sound insulation boards extend to the gap between the second outer frame 12 and the assembly floor 81, thereby improving the sound insulation effect of the floor member 8 and improving the practicality of the present equipment.

[0057] like Fig.12 As shown, the insulation layer 84 provided in this embodiment is a glass wool board, which is used for insulation of the floor slab 8 to improve the insulation effect of the equipment, and the insulation layer 84 is connected to the sound insulation layer 83 and the upper concrete 85 by gluing to fix the insulation layer 84.

[0058] In order to improve the service strength of the assembly floor 81, ribs perpendicular to the reinforcing steel pipes 82 are arranged at equal intervals inside the assembly floor 81. The ribs and the reinforcing steel pipes 82 are connected by bundling, thereby improving the tensile and compressive properties of the assembly floor 81.

[0059] When in use (working), the first reinforcing angle steel 4 and the second reinforcing angle steel 5 are installed on the column 1, and the second reinforcing angle steel 5, the first reinforcing angle steel 4 and the column 1 are tightly connected by the second fastening bolt, thereby improving the stability of the second reinforcing angle steel 5 and the first reinforcing angle steel 4 after installation, and the supporting steel 3 is mounted on the mounting step 6, and the supporting steel 3 is fixed by the fourth fastening bolt, and the crossbeam 2 is installed between the two supporting steels 3, and the crossbeam 2 is fixed by the third fastening bolt, thereby realizing the construction of the rigid frame.

[0060] The first outer frame 11 and the second outer frame 12 are installed on the outside of the floor member 8, and the rigid plug column 13 on the limit frame 10 is inserted into the insertion cavity to realize the preliminary connection between the floor member 8 and the first outer frame 11 and the second outer frame 12. The stability of the limit frame 10 after installation is improved by plugging the limit frame 10 into the limit socket 14. The limit frame 10 and the limit socket 14 are fixed by the first fastening bolt, so that the floor member 8, the first outer frame 11, the second outer frame 12 and the limit frame 10 form an integral structure.

[0061] The floor slab member 8 is hoisted between the two supporting steel sections 3. The rigid plug columns 13 are set to facilitate the hoisting of the floor slab member 8. After the floor slab member 8 is hoisted to the specified position, the corrugated steel plate 7 is installed to fill the gap between the two adjacent floor slab members 8. At this time, the limit frame 10 is mounted on the supporting steel sections 3. By pouring concrete at the concrete pouring layer 9, the rigid plug columns 13 on the limit frame 10 and the corrugated steel plate 7 are fixed, thereby realizing the installation of the floor slab member 8, avoiding the use of too many bolts to reduce the structural strength of the supporting steel sections 3, and can reduce the difficulty of operation for workers, which is convenient for the rapid installation of the floor slab member 8.

[0062] It should be noted that the thermal insulation effect of the floor slab 8 is improved by providing the thermal insulation layer 84 , and the sound insulation effect of the floor slab 8 is improved by providing the sound insulation layer 83 .
