Description

Technical Field

[0001] This utility model relates to the field of building frame technology, specifically a prefabricated two-stage energy-consuming frame structure. Background Technology

[0002] Prefabricated two-stage energy-dissipating frame structure is a building structure that combines prefabricated assembly technology and energy-dissipating design concepts. It is typically used to improve the seismic performance and energy efficiency of buildings.

[0003] The existing technology has the following defects or problems: The existing technology, disclosed in CN204212274U, discloses a building frame structure belonging to the field of building structure engineering technology. It includes four columns and beams connecting adjacent columns; the columns are square steel tubes filled with concrete, and the beams are H-shaped steel beams; it also includes L-shaped plates symmetrically arranged on both sides of the web of the H-shaped steel beam and a support plate located below the H-shaped steel beam; one outer L-face of the L-shaped plate is welded to the square steel tube, and the other outer L-face is bolted to the web of the H-shaped steel beam; one end of the support plate is a convex insertion end, and the square steel tube has a matching insertion hole, which is inserted into the insertion hole and welded to the square steel tube; a vertical reinforcing plate is provided on the bottom surface of the support plate; the top surface of the support plate is bolted to the lower flange plate of the H-shaped steel beam.

[0004] During use, the above-mentioned equipment connects and supports the web of the H-beam by L-shaped plates welded to the square steel pipe. At the same time, the support plates inserted into the square steel pipe provide more stable support for the H-beam.

The overall frame is more stable, and the connectors used are easy to manufacture.

[0005] In practical use, the above-mentioned components cannot be quickly assembled into the building structure, and they lack multi-stage energy dissipation for earthquake resistance, resulting in poor stability. Therefore, it is necessary to propose a prefabricated two-stage energy dissipation frame structure.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figures 1-5 As shown, this utility model provides a technical solution: a prefabricated assembled two-stage energy-consuming frame structure, including a prefabricated floor base 1 and a prefabricated roof slab 2. Multiple prefabricated floor frames 101 are arranged between the prefabricated floor base 1 and the prefabricated roof slab 2. A prefabricated floor slab 102 is arranged between every two prefabricated floor frames 101. Each prefabricated floor frame 101 has symmetrically arranged mounting holes 103 inside. Each prefabricated floor slab 102 has symmetrically fixed connections to a first mounting hole 103 on its exterior. The steel connecting column 104, the precast floor base 1, and the precast floor slab 2 are all fixedly connected with second steel connecting columns 105 that are used to match the mounting holes 103. After the multiple precast floor frames 101 and precast floor slabs 102 are assembled, the two sides form first mounting grooves 3 symmetrically. After the multiple precast floor frames 101 and precast floor slabs 102 are assembled, the back forms a second mounting groove 11. The two first mounting grooves 3 are each equipped with a side shear wall panel 22. The second mounting groove 11 is equipped with a back shear wall panel 23.

[0028] In this embodiment, the prefabricated floor base 1 is hoisted to a designated point, and the prefabricated floor frame 101 is installed with the prefabricated floor base 1 through the mounting holes 103 inside the prefabricated floor frame 101 and the second steel column 105 on the top of the prefabricated floor base 1. Then, the first steel column 104 on the outside of the prefabricated floor slab 102 is connected to the prefabricated floor frame 101. Finally, the prefabricated building frame is completed by connecting the second steel column 105 at the bottom of the prefabricated roof slab 2 to the prefabricated floor frame 101. This facilitates on-site assembly and, compared with the traditional on-site pouring method, has higher construction efficiency, shorter construction period, and better quality control.

[0029] Example 2

[0030] like Figures 1-5 As shown, a prefabricated steel frame 24 is installed inside the first mounting groove 3. Horizontal fixed steel columns 5 are fixedly connected at equal intervals inside the prefabricated steel frame 24. Each horizontal fixed steel column 5 is symmetrically fixedly connected to a U-shaped fixed steel sleeve 6. Each U-shaped fixed steel sleeve 6 has a movable groove 7 inside. A first hydraulic cylinder 8 is rotatably connected inside each movable groove 7. A fixed sleeve 9 is fixedly connected to the telescopic end of each first hydraulic cylinder 8. A connecting anchor bolt 4 is rotatably connected inside each fixed sleeve 9. Each connecting anchor bolt 4 is connected to the prefabricated floor frame 101. A limit sleeve 10 is provided between each connecting anchor bolt 4 and the fixed sleeve 9. First anchor bolts 25 are symmetrically installed inside the prefabricated steel frame 24. The other end of each first anchor bolt 25 extends into the interior of the prefabricated floor frame 101. A first fastening nut 26 is threadedly connected to the outside of each first anchor bolt 25.

[0031] The second mounting slot 11 is symmetrically and fixedly connected with steel beams 12. A first longitudinal fixed steel column 13 and a second longitudinal fixed steel column 14 are fixedly connected between the two steel beams 12. First fixed steel sleeves 15 are equidistantly fixedly connected to the outside of the first longitudinal fixed steel column 13. Each first fixed steel sleeve 15 is symmetrically fixedly connected to the outside of a first steel block 16. A second hydraulic cylinder 17 is rotatably connected between every two first steel blocks 16. Second fixed steel sleeves 18 are equidistantly fixedly connected to the outside of the second longitudinal fixed steel column 14. Each second fixed steel sleeve 18... Each of the 8 is symmetrically fixed with a second steel block 19, and every two second steel blocks 19 are rotatably connected to the telescopic end of the corresponding second oil cylinder 17. Each first fixed steel sleeve 15 is symmetrically provided with a first fixed pin 20 on its exterior, and each second fixed steel sleeve 18 is symmetrically provided with a second fixed pin 21 on its exterior. Each steel beam 12 is symmetrically provided with a second anchor bolt 27 inside its interior. The other end of each second anchor bolt 27 extends into the interior of the precast floor frame 101, and each second anchor bolt 27 is threaded with a second fastening nut 28 on its exterior.

[0032] In this embodiment, the first anchor bolt 25 passes through the precast steel frame 24 and is connected to the precast floor frame 101. The first fastening nut 26 is then locked to achieve a quick connection between the steel beam 12 and the building. Subsequently, each connecting anchor bolt 4 passes through the fixing sleeve 9 and the limiting sleeve 10 and is connected to the precast floor frame 101. Side shear wall panels 22 are installed on the outside of the two first mounting slots 3 to improve aesthetics and seismic resistance. When vibration occurs, the building deforms due to external force majeure. When the building deforms, the connecting anchor bolt 4 drives the fixing sleeve 9, and the fixing sleeve 9 drives the first hydraulic cylinder 8 to perform piston movement, thereby reducing the vibration amplitude of the building and improving the stability of the building.

[0033] Two steel beams 12 are symmetrically installed inside the second mounting groove 11 using the second anchor bolt 27 and the second fastening nut 28, and connected to the precast floor base 1 and the precast roof slab 2. A back shear wall panel 23 is installed on the outside of the second mounting groove 11, which improves the seismic resistance and aesthetics. When the building sways from side to side due to external vibration, the first longitudinal fixed steel column 13 and the second longitudinal fixed steel column 14 between the two steel beams 12 deform, causing the second hydraulic cylinder 17 to move like a piston, which counteracts a certain amount of external force, thereby improving the stability of the building, increasing the frame's strength, reducing vibration, and improving safety. The cooperation of multiple first hydraulic cylinders 8 and second hydraulic cylinders 17 achieves secondary energy dissipation, reducing the building's response to vibration or other loads. It can deform and absorb energy under external force, reducing the direct impact on the building structure.

[0034] The working principle of this embodiment is as follows: During use, the installation steps are as follows: the precast floor base 1 is hoisted to the designated point, and the precast floor frame 101 is installed with the precast floor base 1 through the mounting holes 103 inside the precast floor frame 101 and the second steel column 105 on the top of the precast floor base 1. Then, the first steel column 104 on the outside of the precast floor slab 102 is connected to the precast floor frame 101. Finally, the precast assembly of the building frame is completed by connecting the second steel column 105 at the bottom of the precast floor slab 2 to the precast floor frame 101. This facilitates on-site assembly and, compared with the traditional on-site pouring method, has higher construction efficiency, shorter construction cycle, and better quality control.

[0035] Prefabricated steel frames 24 and steel beams 12 are prefabricated according to the specifications of the first installation groove 3 and the second installation groove 11 formed between different numbers of prefabricated floor frames 101 and prefabricated floor slabs 102. The steel frames 24 and prefabricated floor frames 101 are connected by first anchor bolts 25 passing through them and locked by first fastening nuts 26, thus achieving a quick connection between the steel beams 12 and the building. Subsequently, each connecting anchor bolt 4 is connected to the prefabricated floor frame 101 by passing through a fixing sleeve 9 and a limiting sleeve 10. Side shear wall panels 22 are installed on the outside of the two first installation grooves 3 to improve aesthetics and seismic resistance. When vibration occurs, the building deforms due to external force majeure. When the building deforms, the connecting anchor bolts 4 drive the fixing sleeve 9, and the fixing sleeve 9 drives the first hydraulic cylinder 8 to make piston movement, thereby reducing the vibration amplitude of the building and improving the stability of the building.

[0036] like Figure 5 As shown, the structural component between the two steel beams 12 is a prefabricated integral component. The two steel beams 12 are symmetrically installed inside the second mounting groove 11 by the second anchor bolt 27 and the second fastening nut 28, and connected to the prefabricated floor base 1 and the prefabricated roof slab 2. The back shear wall panel 23 is installed on the outside of the second mounting groove 11, which improves the seismic effect and also enhances the aesthetics. When the building is affected by external vibration and sways from side to side, the first longitudinal fixed steel column 13 and the second longitudinal fixed steel column 14 between the two steel beams 12 deform, causing the second hydraulic cylinder 17 to perform piston movement, which counteracts a certain external force, thereby improving the stability of the building, increasing the frame's robustness, reducing vibration, and improving safety. The cooperation of multiple first hydraulic cylinders 8 and second hydraulic cylinders 17 achieves secondary energy dissipation, reducing the building's response under vibration or other loads. It can deform and absorb energy under external force, reducing the direct impact on the building structure.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
