Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a detachable staggered stacked steel structure module system and its construction method. Background Technology

[0002] Modular steel structure systems have gained attention in the construction industry due to their rapid construction, high integration, environmental friendliness, and recyclability, aligning with the new trend of industrialized construction. However, conventional modular steel structures consume significantly more steel because they have a much larger number of beams and columns. To reduce steel consumption, researchers have recently proposed using staggered stacking of modular steel structures, which effectively reduces the amount of steel used in beams and columns.

[0003] Chinese patent document CN117005548A discloses a steel structure module staggered stacking structure system, including multiple steel structure module units, a first precast floor slab, and load-bearing columns; the multiple steel structure module units are staggered to form a multi-layer rectangular main structure, wherein the number of steel structure module units in the odd-numbered floors of the main structure is one more than the number of steel structure module units in the even-numbered floors; when the total number of floors of the main structure is odd, the load-bearing column is provided between every two adjacent steel structure module units on both sides of the main structure, and a load-bearing column is provided between every two adjacent steel structure module units on the top and bottom sides of the main structure. A first precast floor slab is placed; when the total number of floors in the main structure is even, load-bearing columns are set above the steel structure module units on both sides of the main structure, and the first precast floor slab is set between every two adjacent steel structure module units on the top and bottom floors of the main structure, and the first precast floor slab is set between the load-bearing column on the top floor and the adjacent steel structure module unit; wherein, each steel structure module unit, the first precast floor slab, and the load-bearing column is provided with a connecting unit, and two adjacent connecting units can be inserted into each other, forming a grouting space after the two connecting units are inserted. The defects and deficiencies of this staggered stacked steel structure module structure system are: in order to improve the overall structure, this staggered stacked steel structure module structure system needs to provide connecting units in the steel structure module units, the first precast floor slab, and the load-bearing columns, and two adjacent connecting units can be inserted into each other, forming a grouting space after the two connecting units are inserted, and grout is injected into the grouting space, and after the grout solidifies, the two connecting units are tightly connected. In other words, the steel structure module staggered stacking structure system adopts a wet connection of on-site post-casting, which not only makes on-site construction operations complicated, but also makes the structure system difficult to disassemble later. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a detachable staggered stacked steel structure module system and its construction method, which solves the technical problem that the existing staggered stacked steel structure module system uses grouting wet connection between the floor slabs of adjacent modules, which makes the structure system difficult to disassemble in the later stage.

[0028] S2.

[0031] (III) Beneficial Effects

[0032] The beneficial effects of this invention are as follows: The detachable staggered stacked steel structure module system of this invention includes a module top plate, a module bottom plate, fastening components, concealed components, and multiple steel structure module units. These multiple steel structure module units are staggered to form a multi-layer main structure. The top plate of the steel structure module unit located in the lower layer of the main structure is fixedly installed, and the bottom plate of the steel structure module unit located in the upper layer of the main structure is fixedly installed. The top and bottom plates of adjacent upper and lower layer steel structure module units are detachably connected by fastening components, and the gap between them is filled with concealed components to hide the fastening components. Compared with existing staggered stacked steel structure module systems, the detachable staggered stacked steel structure module system of this invention uses a dry connection for the module top plate, module bottom plate, and fastening components, eliminating the need for on-site concrete pouring, reducing on-site wet work, and this dry connection structure is easy to install and disassemble, simplifying the construction process, and preventing conflicts between components. Furthermore, the use of detachable concealed components not only conceals the connection structure between floor slabs but also reduces the difficulty of later disassembly.

[0033] The detachable staggered stacked steel structure modular system of the present invention has a clear force transmission method in its connection structure. The horizontal tensile force on the first ear plate and the second ear plate can be directly transmitted to the first tie bar and the second tie bar, avoiding the concrete floor slab from cracking. The force transmission effect is more efficient. Therefore, it has greater connection (tie) stiffness and connection (tie) strength, which improves the continuity of the floor slab between modules and the seismic performance of the structure.

[0052] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably. Figure 1 The orientation is used as a reference.

[0053] Example 1:

[0054] Reference Figure 1 and Figure 2 This embodiment provides a detachable staggered stacked steel structure module system, including a module top plate 1, a module bottom plate 2, fastening components 3, concealed components 4, and multiple steel structure module units 5.

[0055] Multiple steel structure module units 5 are stacked in an alternating manner to form a multi-layer main structure. A module top plate 1 is fixedly installed on the top of the steel structure module unit 5 located in the lower layer of the main structure, and a module bottom plate 2 is fixedly installed on the bottom of the steel structure module unit 5 located in the upper layer of the main structure.

[0056] The module top plate 1 and module bottom plate 2 of the adjacent upper and lower steel structure module units 5 are detachably connected by fastening components 3, and the gap between them is concealed by concealing components 4 to conceal fastening components 3.

[0057] The detachable staggered stacked steel structure module system of this embodiment, through the dry connection of the module top plate 1, module bottom plate 2, and fastening component 3, not only realizes the coordinated force between the building structure floor slabs of the staggered stacked steel structure module system compared with the existing grouting wet connection, but also facilitates the later disassembly.

[0058] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the module top plate 1 includes a first reinforced concrete floor slab 11, and a first ear plate 12 is provided on the side of the first reinforced concrete floor slab 11. The module bottom plate 2 includes a second reinforced concrete floor slab 21, and a second ear plate 22 is provided on the side of the second reinforced concrete floor slab 21. Both the first ear plate 12 and the second ear plate 22 are provided with through holes.

[0059] The fastening assembly 3 includes a high-strength screw 31 and a high-strength nut 32. The through holes on the opposing sides of the first ear plate 12 and the second ear plate 22 in the adjacent first reinforced concrete floor slab 11 and the second reinforced concrete floor slab 21 are coaxially arranged, so that a high-strength screw 31 can pass through all the coaxial first ear plates 12 and second ear plates 22. Two high-strength nuts 32 are provided on the high-strength screw 31 corresponding to each first ear plate 12 and second ear plate 22. The two high-strength nuts 32 abut against the front side and the rear side of the first ear plate 12 or the second ear plate 22 respectively, thereby clamping the first ear plate 12 or the second ear plate 22.

[0060] Preferably, a washer 33 is provided between the high-strength nut 32 and the side of the first ear plate 12 or the second ear plate 22. The function of the washer 33 is to protect the surface of the ear plate from being scratched by the high-strength nut 32 and to distribute the pressure of the high-strength nut 32 on the ear plate. It should be noted that the high-strength screw 31, the high-strength nut 32 and the washer 33 are commercially available components that conform to national standards GB / T 1228-2006 and GB / T 1231-2024.

[0061] Preferably, the diameter of the through hole is slightly larger than the diameter of the high-strength screw 31, which provides a certain tolerance for the insertion of the high-strength screw 31 into the first ear plate 12 and the second ear plate 22. In other words, the allowable error of this connection structure is relatively large, reducing the production precision requirements.

[0062] Furthermore, the module top plate 1 also includes a first edge thin steel plate 13, a first tie bar 14, and a first stud 15. The first edge thin steel plate 13 is respectively provided on the left and right sides of the first reinforced concrete floor slab 11. First ear plates 12 are symmetrically welded to the middle of the outer surfaces of the two first edge thin steel plates 13. The inner surface of one of the two first edge thin steel plates 13 is welded to one end of the first tie bar 14 corresponding to the installation area of ​​the first ear plate 12, and the inner surface of the other of the two first edge thin steel plates 13 is welded to the other end of the first tie bar 14 corresponding to the installation area of ​​the first ear plate 12. First studs 15 are also welded to the inner surfaces of the two first edge thin steel plates 13. The first tie bar 14 and the first studs 15 are pre-embedded inside the first reinforced concrete floor slab 11. It should be noted that the central axis of the first ear plate 12 corresponds to that of the first tie bar 14, which allows the horizontal load on the first ear plate 12 to be directly transferred to the first tie bar 14.

[0063] It should be noted that during the factory prefabrication process, the first ear plate 12, the first edge thin steel plate 13, the first tie bar 14 and the first stud 15 are first connected into one piece by welding, and then formed into a whole with the first reinforced concrete floor slab 11 by pouring concrete.

[0064] The module base plate 2 in this embodiment also includes a second edge thin steel plate 23, a second tie bar 24, and a second stud 25. Second edge thin steel plates 23 are respectively provided on the left and right sides of the second reinforced concrete floor slab 21. Second ear plates 22 are symmetrically welded to the middle of the outer surfaces of the two second edge thin steel plates 23. One inner surface of one of the two second edge thin steel plates 23 is welded to one end of the second tie bar 24 corresponding to the installation area of ​​the second ear plate 22, and the other inner surface of the other second edge thin steel plate 23 is welded to the other end of the second tie bar 24 corresponding to the installation area of ​​the second ear plate 22. Second studs 25 are also welded to the inner surfaces of the two second edge thin steel plates 23. The second tie bar 24 and the second stud 25 are embedded inside the second reinforced concrete floor slab 21. It should be noted that the second ear plate 22 corresponds to the central axis of the second tie bar 24, which allows the horizontal load on the second ear plate 22 to be directly transferred to the second tie bar 24.

[0065] It should be noted that the manufacturing process of module base plate 2 and module top plate 1 is the same, and will not be described again here.

[0066] Combination Figure 7 and Figure 8As shown, the concealing component 4 in this embodiment includes a C-shaped covering component 41 and a square filling block 42. The bottom of the C-shaped covering component 41 has a groove for accommodating the first ear plate 12, the second ear plate 22 and the fastening component 3, so that the C-shaped covering component 41 can cover the periphery of the first ear plate 12, the second ear plate 22 and the fastening component 3. Square filling blocks 42 are respectively provided on the front and rear sides of the C-shaped covering component 41, and the square filling blocks 42 are used to fill the gap between the module top plate 1 and the module bottom plate 2.

[0067] Preferably, after the concealed component 4 is assembled in place, the gaps between the C-shaped covering component 41, the square filling block 42, the module top plate 1 and the module bottom plate 2 are filled with expanding foam or other sealant to enhance the waterproof, heat insulation and sound insulation performance of the structure.

[0068] See Figure 9 The steel structure module unit 5 includes module column 51, module bottom beam 52, module top beam 53, module bottom corner piece 54 and module top corner piece 55.

[0069] A bottom corner piece 54 is provided in the corner area of ​​the bottom beam 52 of the module, and a top corner piece 55 is provided in the corner area of ​​the top beam 53 of the module. The bottom corner piece 54 and the top corner piece 55 of the module are connected by a module column 51.

[0070] The bottom corner piece 54 of the upper steel structure module unit 5 can be placed on the module column 51 of the lower steel structure module unit 5, and part of the lower end face of the module column 51 of the upper steel structure module unit 5 can be placed on the bottom corner piece 54 of the lower steel structure module unit 5, so that the upper surface of the module top beam 53 of the lower steel structure module unit 5 is flush with the upper surface of the module bottom beam 52 of the upper steel structure module unit 5.

[0071] Furthermore, the upper surfaces of the top corner piece 55 and the module column 51 are provided with protrusions, and the lower surfaces of the bottom corner piece 54 and the module column 51 are provided with slots. When the upper steel structure module unit 5 is placed on the lower steel structure module unit 5, the protrusions are inserted into the slots one by one, so that the upper steel structure module unit 5 and the lower steel structure module unit 5 are nested together.

[0072] It should be noted that the module column 51, module bottom beam 52, module top beam 53, module bottom corner piece 54, and module top corner piece 55 are integrated by welding or high-strength bolts. The overall shape of the steel structure module unit 5 is a cuboid, with a length ranging from 3 to 14m, a width ranging from 2 to 4.5m, and a height ranging from 2 to 4.5m.

[0073] Furthermore, the number of first ear plates 12 is even, and an even number of first ear plates 12 are fixedly installed on the first reinforced concrete floor slab 11 at equal intervals; the number of second ear plates 22 is odd, and an odd number of second ear plates 22 are fixedly installed on the second reinforced concrete floor slab 21. When the first reinforced concrete floor slab 11 and the second reinforced concrete floor slab 21 are close and aligned, the second ear plates 22 are inserted one-to-one between two first ear plates 12, and the distance between them is 0.05-1m. Alternatively, the number of first ear plates 12 is odd, the number of second ear plates 22 is even, and the first ear plates 12 are inserted one-to-one between two second ear plates 22.

[0074] Furthermore, the module top plate 1 is disposed on top of the module top beam 53 and is supported by the module top beam 53; the module bottom plate 2 is disposed on top of the module bottom beam 52 and is supported by the module bottom beam 52. Preferably, the module top plate 1 and the module bottom plate 2 can be stably connected to the module beam of the steel structure module unit 5 by means of a third stud connection.

Specifically, the modular top plate 1 is fixed to the modular top beam 53 by a third bolt, and the modular bottom plate 2 is fixed to the modular bottom beam 52 by a third bolt. Furthermore, the bottom of the lowest steel structure modular unit 5 may or may not have a modular bottom plate 2; the top of the highest steel structure modular unit 5 may or may not have a modular top plate 1.

[0078] S2. Assembly of Steel Structure Module Unit 5: At the construction site, first, two steel structure module units 5 are hoisted and lowered to the preset positions, with a gap between them. Then, a third steel structure module unit 5 is hoisted and lowered to the upper side between the two steel structure module units 5, so that the two lower steel structure module units 5 and the third upper steel structure module unit 5 are nested together. Specifically, the bottom corner piece 54 of the upper steel structure module unit 5 rests on the module column 51 of the lower steel structure module unit 5, and part of the lower end face of the module column 51 of the upper steel structure module unit 5 rests on the bottom corner piece 54 of the lower steel structure module unit 5, thereby making the upper and lower surfaces of the module top plate 1 and the module bottom plate 2 flush.

[0079] S3. Fastening components 3 are installed between the top plate 1 and bottom plate 2 of two adjacent steel structure module units 5 to form a detachable connection. Specifically, high-strength screws 31, high-strength nuts 32 and washers 33 are provided at the first ear plate 12 and the second ear plate 22 between the top plate 1 and the bottom plate 2, and the high-strength nuts 32 are tightened to form an effective connection.

[0080] S4. After completing the assembly of fastening component 3, first install concealed component 4 in the gap between module top plate 1 and module bottom plate 2, and then fill the gap between concealed component 4 and module top plate 1 and module bottom plate 2 with sealant, thereby concealing the horizontal connection structure of the floor between modules and reducing the impact on subsequent decoration.
