Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a prefabricated steel structure for high-rise buildings. Background Technology

[0002] High-rise steel structures generally refer to structures with six or more floors, which are mainly constructed by connecting or welding structural steel sections and plates into components, and then connecting and welding them together.

[0003] Chinese patent CN219863303U describes a prefabricated steel structure for high-rise buildings, including columns, longitudinal beams, and transverse beams. First connecting seats are fixedly connected to both sides of the outer wall of the columns, and second connecting seats are fixedly connected to both sides of the inner wall of the columns. Connecting long bolts are inserted into both sides of the columns. This invention, through the first and second connecting seats, respectively supporting and limiting the longitudinal and transverse beams, allows the downward pressure of the longitudinal and transverse beams to be vertically transmitted to the columns, enabling the columns to bear vertical downward pressure. This, in turn, transfers stress to the foundation, preventing tensile deformation of the columns. Simultaneously, the pre-reserved gaps between the longitudinal and transverse beams and the columns, as well as the spacing between the first connecting bolts, connecting long bolts, and the first and second connecting strip holes, accommodate the expansion and contraction of the longitudinal and transverse beams, preventing the expansion and contraction forces of the longitudinal and transverse beams from being applied to the columns, thus improving safety.

[0004] However, in actual use, the aforementioned patent requires the assembly of the column, crossbeam, and longitudinal beam with ten bolts, which necessitates drilling multiple mounting holes in the column. This not only affects the column's support performance but also causes inconvenience to the installation work. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a prefabricated steel structure for high-rise buildings.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

[0007] A prefabricated steel structure for high-rise buildings includes columns and four bolts. The columns have crossbeams on both the front and rear sides, and longitudinal beams movably connected to both the left and right sides. A first groove is formed at the top of the column, and a connecting strip is movably inserted into the inner cavity of the first groove. Two fixing blocks are fixedly connected to both the left and right sides of the connecting strip. The fixing blocks are snapped onto the outer side of the column and movably inserted into the inner sides of the crossbeams and longitudinal beams. Four first through holes are formed on both the front and rear sides of the column, and two second through holes are formed on both the front and rear sides of the fixing blocks. Four fixing plates are fixedly connected to the inner side of the crossbeams, and two third through holes are formed on the fixing plates.

[0008] Preferably, each end of the longitudinal beam is provided with four second grooves, which are matched with the column.

[0009] Preferably, the cross-sections of the fixing block and the connecting strip are both U-shaped.

[0010] Preferably, the bolt moves through adjacent first through hole, second through hole and third through hole, and the bolt is matched with the first through hole, second through hole and third through hole respectively.

[0011] Preferably, the four fixing plates are located near the front and rear sides of the crossbeam, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model relates to a prefabricated steel structure for high-rise buildings. When assembling columns, beams, and longitudinal beams, the device only requires the installation of the connecting strip and four fixing blocks as a whole. Then, the beams and longitudinal beams are moved to the designated positions and finally fixed with four bolts. The operation is simple, and the device uses fewer bolts, so there is no need to open multiple mounting holes on the columns, which greatly improves the support performance of the columns and facilitates the installation work.

[0014] 2. This utility model provides a prefabricated steel structure for high-rise buildings. The device does not require mounting holes on the crossbeams. It is connected to the crossbeams by fixing plates and bolts. The fixing plates not only facilitate the installation work, but also enhance the support performance of the crossbeams.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a prefabricated steel structure for high-rise buildings, including a column 1 and four bolts 8. The column 1 is provided with a crossbeam 3 on both the front and rear sides, and a longitudinal beam 2 is movably inserted into the left and right sides of the column 1. The longitudinal beam 2 is provided with four second grooves 13 at both ends. The second grooves 13 match the column 1. The top of the column 1 is provided with a first groove 4, and a connecting strip 5 is movably inserted into the inner cavity of the first groove 4.

[0028] Two fixing blocks 6 are fixedly connected to both the left and right sides of the connecting strip 5. The fixing blocks 6 are snapped onto the outside of the column 1. The cross-section of both the fixing blocks 6 and the connecting strip 5 is U-shaped. The fixing blocks 6 are movably inserted into the inside of the crossbeam 3 and the longitudinal beam 2. Four first through holes 9 are opened on both the front and rear sides of the column 1. Two second through holes 10 are opened on both the front and rear sides of the fixing blocks 6. Four fixing plates 7 are fixedly connected to the inside of the crossbeam 3. The four fixing plates 7 are close to the front and rear sides of the crossbeam 3 respectively. Two third through holes 11 are opened on the fixing plates 7. Bolts 8 movably pass through the adjacent first through holes 9, second through holes 10 and third through holes 11. Bolts 8 are matched with the first through holes 9, second through holes 10 and third through holes 11 respectively.

[0029] Working principle: This utility model relates to a prefabricated steel structure for high-rise buildings. During use, the connecting strip 5 and the four fixing blocks 6 are moved as a whole to directly above the column 1, and then moved downwards. The connecting strip 5 moves into the inner cavity of the first groove 4, and the fixing blocks 6 are then engaged with the side wall of the column 1. Figure 2 As shown, then move the longitudinal beam 2 and insert it between two adjacent fixing blocks 6, so that the longitudinal beam 2 is inserted into the inner side of the column 1. Then move the crossbeam 3 until it is inserted between two adjacent fixing blocks 6. At this time, the fixing plate 7 corresponds to the adjacent fixing block 6. Then move the bolt 8 and pass the bolt 8 through the first through hole 9, the second through hole 10 and the third through hole 11. Then tighten the bolt 8.

[0030] When assembling the column 1, crossbeam 3 and longitudinal beam 2, the device only requires the first installation of the connecting strip 5 and four fixing blocks 6 as a whole. Then, the crossbeam 3 and longitudinal beam 2 are moved to the designated position and finally fixed with four bolts 8. The operation is simple and the device uses few bolts, so there is no need to open multiple mounting holes on the column 1, which greatly improves the support performance of the column 1 and facilitates the installation work.

[0031] In addition, the device does not require mounting holes on the crossbeam 3. It is connected to the bolts 8 via the fixing plate 7. The fixing plate 7 not only facilitates the installation work, but also enhances the support performance of the crossbeam 3.
