Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a detachable staggered stacked steel structure module system and a construction method thereof. Background Art

[0002] The steel structure module system has attracted attention from the construction industry because of its fast construction speed, high integration, green environmental protection, disassembly and recycling, and conformity with the new trend of building industrialization. Conventional steel structure modules have significantly more beam and column components than conventional steel structure systems, resulting in a large amount of steel. In order to reduce the amount of steel used, in recent years, some researchers have proposed the use of staggered stacked steel structure modules, which can effectively reduce the amount of steel used in beams and columns.

[0003] Chinese patent document CN117005548A discloses a steel structure module staggered stacking structure system, comprising a plurality of steel structure module units, a first prefabricated floor slab and load-bearing columns; a plurality of the steel structure module units are staggered and stacked to form a multi-layer rectangular main structure, and the odd-numbered floors of the main structure have one more steel structure module unit than the even-numbered floors; when the total number of floors of the main structure is odd, the load-bearing columns are arranged between each adjacent two of the steel structure module units on both sides of the main structure, and the load-bearing columns are arranged between each adjacent two of the steel structure module units on the top and bottom floors of the main structure. The first prefabricated floor is set; when the total number of floors of the main structure is an even number, the load-bearing columns are set above the steel structure module units on both sides of the main structure, the first prefabricated floor is set between each two adjacent steel structure module units on the top and bottom floors of the main structure, and the first prefabricated floor is set between the load-bearing columns on the top floor and the adjacent steel structure module units; wherein, the steel structure module units, the first prefabricated floor and the load-bearing columns are all provided with connecting units, and two adjacent connecting units can be plugged in, and a grouting space is formed after the two connecting units are plugged in. The defects and shortcomings of the staggered stacking structure system of steel structure modules are: in order to improve the integrity of the structure, the staggered stacking structure system of steel structure modules needs to be provided with connecting units in the steel structure module units, the first prefabricated floor and the load-bearing columns, and two adjacent connecting units can be plugged in, and a grouting space is formed after the two connecting units are plugged in, and slurry is injected into the grouting space, and the two connecting units are tightly connected after the grouting solidifies. That is to say, the staggered stacking structural system of the steel structure modules adopts a wet connection that is poured on site, which not only complicates the on-site construction operation, but also makes the structural system difficult to disassemble at a later stage. Summary of the invention

[0004] 1. Technical issues to be resolved

[0052] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is used as a reference.

[0053] Embodiment 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, a fastening assembly 3, a hidden component 4 and a plurality of steel structure module units 5.

[0055] A plurality of steel structure module units 5 are stacked in an interlaced manner to form a multi-layer main structure, a module top plate 1 is fixedly arranged 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 arranged on the bottom of the steel structure module unit 5 located in the upper layer of the main structure;

[0056] The module top plates 1 and module bottom plates 2 of the adjacent upper and lower steel structure module units 5 are detachably connected via fastening components 3 , and a gap between the two is formed by a concealing member 4 to conceal the fastening components 3 .

[0057] The detachable staggered steel structure module system of this embodiment, through the dry connection of the module top plate 1, the module bottom plate 2, and the fastening assembly 3, compared with the existing grouting wet connection, not only realizes the coordinated force between the building structure floors of the staggered steel structure module system, 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 11, and a first ear plate 12 is arranged on the side of the first reinforced concrete floor 11. The module bottom plate 2 includes a second reinforced concrete floor 21, and a second ear plate 22 is arranged on the side of the second reinforced concrete floor 21. Through holes are opened on the first ear plate 12 and the second ear plate 22.

[0059] The fastening assembly 3 includes a high-strength screw 31 and a high-strength nut 32. The through holes on the first ear plates 12 and the second ear plates 22 on the opposite sides of the adjacent first reinforced concrete floor slabs 11 and the second reinforced concrete floor slabs 21 are coaxially arranged, so that one high-strength screw 31 can pass through all the coaxial first ear plates 12 and the second ear plates 22. Two high-strength nuts 32 are arranged on the high-strength screw 31 corresponding to each first ear plate 12 and the second ear plate 22. The two high-strength nuts 32 are respectively abutted against the front side and the rear side of the first ear plate 12 or the second ear plate 22, 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 washer 33 is provided to protect the surface of the ear plate from being scratched by the high-strength nut 32 and to disperse the pressure of the high-strength nut 32 on the ear plate.

[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 high-strength screw 31 to be inserted into the first ear plate 12 and the second ear plate 22. In other words, the allowable error of the connection structure is 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 bolt 15. The first edge thin steel plates 13 are respectively arranged on the left and right sides of the first reinforced concrete floor 11, and the first ear plates 12 are symmetrically welded to the middle of the outer side surfaces of the two first edge thin steel plates 13, the inner side 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 side 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, and the first bolt 15 is also welded to the inner side surfaces of the two first edge thin steel plates 13, and the first tie bar 14 and the first bolt 15 are pre-buried inside the first reinforced concrete floor 11. It should be noted that the first ear plate 12 corresponds to the central axis of the first tie bar 14, so that the horizontal load on the first ear plate 12 can 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 bolt 15 are first connected into one by welding, and then formed into a whole with the first reinforced concrete floor slab 11 by pouring concrete.

[0064] The module bottom plate 2 of this embodiment also includes a second edge thin steel plate 23, a second tie bar 24 and a second bolt 25. The second edge thin steel plates 23 are respectively arranged on the left and right sides of the second reinforced concrete floor 21, and the second ear plates 22 are symmetrically welded to the middle of the outer side surfaces of the two second edge thin steel plates 23, the inner side 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 second ear plate 22 installation area, and the inner side surface of the other of the two second edge thin steel plates 23 is welded to the other end of the second tie bar 24 corresponding to the second ear plate 22 installation area, and the second bolt 25 is also welded to the inner side surfaces of the two second edge thin steel plates 23, and the second tie bar 24 and the second bolt 25 are pre-embedded in the second reinforced concrete floor 21. It should be noted that the second ear plate 22 corresponds to the central axis of the second tie bar 24, so that the horizontal load on the second ear plate 22 can be directly transferred to the second tie bar 24.

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

[0066] Combination Figure 7 and Figure 8As shown, the concealed member 4 of this embodiment includes a C-shaped covering member 41 and a square filling block 42. A groove for accommodating the first ear plate 12, the second ear plate 22 and the fastening assembly 3 is provided at the bottom of the C-shaped covering member 41, so that the C-shaped covering member 41 can be arranged around the first ear plate 12, the second ear plate 22 and the fastening assembly 3, and the square filling blocks 42 are respectively arranged on the front and rear sides of the C-shaped covering member 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 foam or other sealants to enhance the waterproof, heat-insulating and sound-insulating properties of the structural building.

[0071] Furthermore, the upper surfaces of the module top corner piece 55 and the module column 51 are provided with protrusions, and the lower surfaces of the module 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.
