Description

Technical Field

[0001] This invention relates to the field of building technology, and more specifically to a building steel structure and its construction process. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of components such as beams, columns, and trusses made of steel sections and plates. As domestic buildings increasingly move towards high-rise and super high-rise structures, constructing rooftop gardens, greenhouses, or other facilities on the rooftops of high-rise or super high-rise buildings has become a viable option. Steel structures offer advantages such as easy assembly and disassembly, recyclability, and modular prefabrication in factories, making them a promising technology. However, if the top floor is subsequently modified, it becomes difficult to guarantee the accurate installation of the modified structure. Since top-floor buildings are prone to slight deformations over long-term use, this can lead to safety hazards in the modified structure. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a building steel structure and its construction process, which has the advantage of enabling safe and stable construction on the top of high-rise or super high-rise buildings.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A construction process for steel structures includes the following steps:

[0006] S1: Detect the top of the building under construction to determine the load-bearing location;

[0007] S2: Install the base frame at the top edge and load-bearing position of the building to be constructed;

[0008] S3: Install the bottom beam between the base frames and check the levelness of the bottom beam;

[0009] S4: Install the base plate and positioning components on the bottom beam to obtain the building base plate;

[0010] S5: Install steel structure components on the building's foundation slab to complete the assembly of the building's steel structure.

[0011] The detection method in step S1 is ultrasonic detection.

[0012] In step S2, the base frame includes a load-bearing base frame and an edge base frame.

[0013] In step S3, a level is installed in the middle of the bottom beam.

[0014] The steel structure components include modular structural components such as doors, windows, wall panels, and roofs.

[0015] The base frame includes a load-bearing column and four secondary load-bearing rings. The four secondary load-bearing rings are evenly arranged around the outside of the load-bearing column. Multiple support rods are slidably connected to the load-bearing column. The multiple support rods are divided into two corresponding groups, and each support rod is fixed to the corresponding secondary load-bearing ring. A load-bearing plate is fixed to the upper side of the load-bearing column, and a pressing plate is fixed to the upper side of the load-bearing plate. The bottom beam and positioning components are all arranged between the load-bearing plate and the pressing plate.

[0016] Each of the support rods is fixed with a positioning nut, and a buffer plate is fixed to the outside of the positioning nut. Each of the secondary load-bearing rings is provided with a through hole corresponding to the support rod. The side of the load-bearing column is provided with a sliding groove corresponding to the support rod, and the inside of the sliding groove is filled with filling foam.

[0017] A placement groove is provided on the upper side of the load-bearing column.

[0018] The positioning element includes a positioning strip and a positioning block.

[0019] A building steel structure includes multiple base frames, with a bottom beam installed between corresponding two base frames. A bottom plate and positioning components are installed on the upper side of the bottom beam, and steel structural components are installed on the bottom plate. Attached Figure Description

[0032] A construction process for steel structures includes the following steps:

[0033] S1: Detect the top of the building under construction to determine the load-bearing location;

[0034] S2: Install the base frame 000 at the top edge and load-bearing position of the building to be constructed;

[0035] S3: Install the bottom beam 010 between the base frames 000 and check the levelness of the bottom beam 010;

[0036] S4: Install the base plate 020 and positioning component 030 on the bottom beam 010 to obtain the building base plate;

[0037] S5: Install steel structure components on the building's foundation slab to complete the assembly of the building's steel structure.

[0038] Because the top of the building to be constructed is detected in advance during the assembly of the building steel structure, it can be ensured that the base frame 000 can be installed on the top edge and load-bearing position of the building to be constructed. This ensures that the building steel structure installed on the base frame 000 can bear the load through the load-bearing position, thereby improving the load-bearing capacity of the reconstructed building and enhancing its safety.

[0039] At the same time, since the bottom beam 010 can be leveled during installation, the resulting building base plate can be leveled, thus avoiding the construction steel structure from becoming skewed and causing safety hazards in the renovated building.

[0040] The detection method in step S1 is ultrasonic detection; thus, it can be ensured that the top of the building under construction is not damaged when it is detected, and the top floor of the building under construction is not damaged.

[0041] In step S2, the base frame 000 includes a load-bearing base frame and an edge base frame. The outer surface of the load-bearing base frame is cylindrical, and the outer surface of the edge base frame is flat. This allows the load-bearing capacity and resistance to deformation of the load-bearing base frame to be improved through its shape, thus preventing the load-bearing base frame from deforming due to the shift of the overall center of gravity of the building during the load-bearing process.

[0042] At the same time, the edge frame can ensure a certain resistance to deformation while allowing the flat part to fit snugly against the top edge of the building to be constructed, thereby avoiding gaps between the edge frame and the top edge of the building to be constructed.

[0043] like Figure 6-7 As shown:

[0044] In step S3, a level is installed in the middle of the bottom beam 010; thus, the levelness of the bottom beam 010 can be detected at any time during the construction of the building steel structure, thereby ensuring that the side surface of the installed building base is level, and thus ensuring that the center of gravity of the completed building steel structure does not tilt, further ensuring the safety of the renovated building.

[0045] The steel structure components include modular structural components such as doors, windows, wall panels, and roofs.

[0046] like Figure 8-10 As shown:

[0047] The base frame 000 includes a load-bearing column 110 and four secondary load-bearing rings 120. The four secondary load-bearing rings 120 are evenly arranged around the outside of the load-bearing column 110. Multiple support rods 130 are slidably connected to the load-bearing column 110. The multiple support rods 130 are divided into two corresponding groups, and each of the multiple support rods 130 is snapped onto the corresponding secondary load-bearing ring 120. A load-bearing plate 140 is threadedly connected to the upper side of the load-bearing column 110. A pressing plate 150 is threadedly connected to the upper side of the load-bearing plate 140. The bottom beam 010 and the positioning component 030 are both arranged between the load-bearing plate 140 and the pressing plate 150.

[0048] When installing the base frame 000 at the top edge or load-bearing location of the building under construction, the four secondary load-bearing rings 120 can be fixed in the installation position first. Then, the load-bearing column 110 is installed between the four secondary load-bearing rings 120. Next, the corresponding support rods 130 can be inserted into the secondary load-bearing rings 120. Then, the angle of the load-bearing column 110 can be adjusted, and all the support rods 130 can be fixed on the secondary load-bearing rings 120. Thus, the secondary load-bearing rings 120 and the support rods 130 can provide support for the load-bearing column 110. 0. Ensure the position of the load-bearing column 110 is fixed, then the load-bearing plate 140 can be installed on the load-bearing column 110, then the bottom beam 010 and the positioning component 030 can be installed at the corresponding positions on the load-bearing plate 140, then the pressing plate 150 can be installed on the upper side of the load-bearing plate 140, and then the bottom beam 010 can be limited by the pressing plate 150, thereby preventing the bottom beam 010 from sliding during the installation process. At the same time, the positioning component 030 can limit the pressing plate 150, preventing the pressing plate 150 from tilting due to uneven force.

[0049] Meanwhile, during the adjustment of the angle of the load-bearing column 110, the construction workers can install a level on the top of the load-bearing column 110 to adjust its position. This ensures that the adjusted load-bearing column 110 is vertically installed in its position, thus ensuring that the weight of the renovated building is fully distributed to the load-bearing position. This prevents high-rise or super high-rise buildings from being unable to support the weight of the renovated building, which could lead to safety hazards.

[0050] Further:

[0051] Each of the multiple support rods 130 is connected to a positioning nut 131 by a thread. A buffer plate 132 is glued to the outside of the positioning nut 131. Each of the secondary load-bearing rings 120 is provided with a through hole 121 corresponding to the support rod 130. The side of the load-bearing column 110 is provided with a sliding groove 111 corresponding to the support rod 130. The inner side of the sliding groove 111 is filled with filling foam 160.

[0052] When it is necessary to fix the support rod 130 on the secondary load-bearing ring 120, the support rod 130 can slide on the corresponding slide groove 111, so that the movable end of the support rod 130 can pass through the through hole 121. Then the support rod 130 can be pressed down and the positioning nut 131 can be adjusted to the corresponding position so that the outer side of the positioning nut 131 can fit with the inner side of the secondary load-bearing ring 120, thereby fixing the support rod 130 on the secondary load-bearing ring 120. Thus, the position fixing work of the load-bearing column 110 can be completed through multiple secondary load-bearing rings 120 and multiple support rods 130.

[0053] Meanwhile, when the center of gravity of the reconstructed building shifts, causing 100 to be subjected to tilting force, the positioning nut 131 can adhere to the inner side of the secondary load-bearing ring 120, allowing the secondary load-bearing ring 120 to provide support to the load-bearing column 110 through the support rod 130, thereby maintaining the stability of the position of the load-bearing column 110. At this time, the buffer plate 132 can buffer the positioning nut 131, thereby preventing the positioning nut 131 from causing damage to the secondary load-bearing ring 120, thereby extending the service life of the secondary load-bearing ring 120, and thus effectively improving the safety of the building steel structure during long-term use.

[0054] Meanwhile, the foam filling 160 can limit the position of the support rod 130 on the slide groove 111, preventing the support rod 130 from moving up and down after it is positioned, which would result in the support rod 130 and the secondary load-bearing ring 120 being unable to limit the position of the load-bearing column 110.

[0055] Further:

[0056] The upper side of the load-bearing column 110 is provided with a placement groove 112, so that a level can be placed inside the placement groove 112, thereby facilitating the adjustment of the position of the load-bearing column 110.

[0057] like Figure 5 As shown:

[0058] The positioning component 030 includes a positioning strip and a positioning block; thus, the positioning strip can be used to position the bottom beam 010, preventing the bottom beam 010 from overturning after being subjected to large and concentrated gravity. At the same time, the positioning block can be used to position the pressing sheet 150, thereby preventing the pressing sheet 150 from tilting after being subjected to large and concentrated gravity. Furthermore, the positioning strip and positioning block can be used to position the building base plate, thereby facilitating the overall stability of the building steel structure.

[0059] A building steel structure includes multiple base frames 000, a bottom beam 010 is installed between two corresponding base frames 000, a bottom plate 020 and positioning parts 030 are installed on the upper side of the bottom beam 010, and steel structure components are installed on the bottom plate 020.

[0060] This ensures that when installing or renovating a building on the top of a high-rise or super high-rise building, the base frame 000 can guarantee that the steel structure of the building can be installed at the load-bearing position on the top of the high-rise or super high-rise building, thereby ensuring that the weight of the steel structure of the building will not affect the high-rise or super high-rise building and cause safety hazards.

[0061] At the same time, the base frame 000 can ensure that the weight of the building steel structure can be transferred to the load-bearing position of the high-rise or super high-rise building through the base frame 000, thereby further preventing the building steel structure from affecting the top of the high-rise or super high-rise building.
