Technical Field

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

[0002] Prefabricated buildings are a type of construction that uses industrialized production methods to assemble standardized components on-site. Because prefabricated buildings have advantages such as fast construction speed, controllable quality, and environmental protection and energy saving, they are widely used in modern construction.

[0003] Some prefabricated building frame structures still have some problems. For example, some components may slide unexpectedly after assembly, making it inconvenient to fix the assembled components. Moreover, the fixing structure is relatively complex and can easily affect assembly efficiency.

[0004] Therefore, we propose a prefabricated building frame structure to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated building frame structure to solve the problems mentioned in the background art, such as the inconvenience of fixing the assembled components and the relatively complex fixing structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building frame structure, including support beams and crossbeams, with a crossbeam at the top between the support beams, connecting frames fixedly connected to the left and right sides of the crossbeams, support blocks fixedly connected to the top of the front and rear ends of the support beams, a protective shell fixedly connected to the top of the support beam near the outside, connecting plates at the front and rear ends inside the protective shell, a limit spring installed at the top between the connecting plates, a damper installed inside the limit spring, a limit rod fixedly connected to the end of the connecting plate near the outside, limit grooves respectively opened at the front and rear ends of the connecting frame near the outside, and a guide groove opened at the bottom of the inside of the protective shell.

[0007] As a further technical solution of this utility model, the support beam is arranged on the left and right sides of the crossbeam, and the connecting frame is clipped to the top of the support beam.

[0008] As a further technical solution of this utility model, the limiting rod is embedded inside the limiting groove, and the connecting frame is set at the top of the support block.

[0009] As a further technical solution of this utility model, reinforcing rods are provided on the left and right sides between the support beam and the crossbeam. The upper and lower ends of the reinforcing rods are fixedly connected to a second fixing frame and a first fixing frame. Fixing holes are respectively opened inside the first fixing frame and the support beam, and fixing bolts are provided inside the fixing holes.

[0010] As a further technical solution of this utility model, the first fixing frame and the second fixing frame are respectively clamped on the left and right sides of the outside of the support beam and the crossbeam, and the first fixing frame is fixed to the outside of the support beam through fixing holes and fixing bolts.

[0011] As a further technical solution of this utility model, a sliding groove is fixedly connected to the top of the inside of the support beam, and a slider is fixedly connected to the top of the connecting plate, and the slider slides back and forth inside the sliding groove.

[0012] As a further technical solution of this utility model, the front and rear ends of the bottom of the protective shell are respectively fixedly connected to a fixing block, and the fixing block is movably hinged to a hinge rod, and the front and rear ends of the bottom of the hinge rod are fixedly connected to a limit plate.

[0013] As a further technical solution of this utility model, the hinge rod rotates inside the fixed block, and the limiting plate is disposed at one end of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated building frame structure not only facilitates the limiting of the beams and increases the strength of the beams, but also facilitates the limiting of the connecting plates;

[0015] (1) By setting up a connecting plate, a limiting rod, a limiting groove, a limiting spring and a damper, the connecting frames on both sides of the crossbeam are placed at the top of the outside of the support beam. The support block supports the connecting frame. After it is placed, the hinge rod is rotated to make the connecting plate lose its fixation. The limiting spring uses its own elasticity to make the limiting rod embedded in the limiting groove, thereby limiting and fixing the connecting frame and preventing the crossbeam from sliding left and right outside the support beam.

[0016] (2) By setting a first fixing frame, fixing bolts, a second fixing frame, fixing holes and reinforcing rods, the first fixing frame is snapped onto the outside of the support beam so that the fixing holes on the first fixing frame and the fixing holes on the support beam are aligned. After the fixing holes are aligned, the fixing bolts are screwed into the fixing holes to install and fix the first fixing frame. When installing the first fixing frame, the second fixing frame is supported at the bottom of the outside of the crossbeam. The second fixing frame and the reinforcing rod can support the crossbeam, increase the strength of the crossbeam during use, and prevent the crossbeam from bending and being damaged.

[0017] (3) By setting a slider, a groove, a hinge rod, a fixing block and a limiting plate, the limiting plate is set at the end of the connecting plate near the outside, so as to limit the connecting plate and prevent the connecting plate from moving the limiting rod. When it is necessary to make the limiting rod embedded in the limiting groove, the hinge rod is rotated again, and the hinge rod drives the limiting plate to rotate downward, so that the limiting plate moves away from one end of the connecting plate, thereby making the connecting plate lose its fixation. When the connecting plate moves, the slider will slide inside the groove, and the groove can limit the connecting plate through the slider. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4This utility model provides an embodiment of a prefabricated building frame structure, including a support beam 1 and a crossbeam 6. A crossbeam 6 is provided at the top between the support beams 1. A connecting frame 5 is fixedly connected to the left and right sides of the crossbeam 6. A support block 4 is fixedly connected to the top of the front and rear ends of the support beam 1. A protective shell 11 is fixedly connected to the top of the support beam 1 near the outside. A connecting plate 9 is provided at the front and rear ends inside the protective shell 11. A limit spring 14 is installed at the top between the connecting plates 9. A damper 17 is provided inside the limit spring 14. A limit rod 12 is fixedly connected to the end of the connecting plate 9 near the outside. Limit grooves 13 are respectively opened at the front and rear ends of the connecting frame 5 near the outside. A guide groove 21 is opened at the bottom of the protective shell 11.

[0025] The support beam 1 is set on the left and right sides of the crossbeam 6, the connecting frame 5 is clipped on the top of the support beam 1, the limiting rod 12 is embedded in the limiting groove 13, and the connecting frame 5 is set on the top of the support block 4.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the connecting frames 5 on both sides of the crossbeam 6 are placed at the top outside the support beam 1. The support block 4 supports the connecting frames 5. After they are placed, the hinge rod 18 is rotated so that the connecting plate 9 is no longer fixed. The limiting spring 14 uses its own elasticity to make the limiting rod 12 embedded in the limiting groove 13, thereby limiting and fixing the connecting frame 5 and preventing the crossbeam 6 from sliding left and right outside the support beam 1.

[0027] Reinforcing rods 10 are provided on the left and right sides between the support beam 1 and the crossbeam 6. The upper and lower ends of the reinforcing rods 10 are fixedly connected to the second fixing frame 7 and the first fixing frame 2. The first fixing frame 2 and the support beam 1 are respectively provided with fixing holes 8. Fixing bolts 3 are provided inside the fixing holes 8. The first fixing frame 2 and the second fixing frame 7 are respectively locked on the left and right sides of the outside of the support beam 1 and the crossbeam 6. The first fixing frame 2 fixes the outside of the support beam 1 through the fixing holes 8 and the fixing bolts 3.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the first fixing bracket 2 is snapped onto the outside of the support beam 1 so that the fixing hole 8 on the first fixing bracket 2 is aligned with the fixing hole 8 on the support beam 1. After the fixing holes 8 are aligned, the fixing bolt 3 is screwed into the inside of the fixing hole 8 to install and fix the first fixing bracket 2. When installing the first fixing bracket 2, the second fixing bracket 7 is supported at the bottom of the outside of the crossbeam 6. The second fixing bracket 7 and the reinforcing rod 10 can support the crossbeam 6, increase the strength of the crossbeam 6 during use, and prevent the crossbeam 6 from bending and being damaged.

[0029] The top of the support beam 1 is fixedly connected to a slide groove 16, and the top of the connecting plate 9 is fixedly connected to a slider 15. The slider 15 slides back and forth inside the slide groove 16. The front and rear ends of the bottom of the protective shell 11 are fixedly connected to fixed blocks 19 respectively. The inside of the fixed block 19 is movably hinged to a hinge rod 18. The front and rear ends of the bottom of the hinge rod 18 are fixedly connected to limit plates 20. The hinge rod 18 rotates inside the fixed block 19. The limit plate 20 is set at one end of the connecting plate 9.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the limiting plate 20 is located at the end of the connecting plate 9 near the outside, thereby limiting the connecting plate 9 and preventing the connecting plate 9 from moving the limiting rod 12. When it is necessary to embed the limiting rod 12 inside the limiting groove 13, the hinge rod 18 is rotated again. The hinge rod 18 drives the limiting plate 20 to rotate downward, causing the limiting plate 20 to rotate away from one end of the connecting plate 9, thereby making the connecting plate 9 unfixed. When the connecting plate 9 moves, the slider 15 will slide inside the slide groove 16. The slide groove 16 can limit the connecting plate 9 through the slider 15.

[0031] Working principle: In use, pulling the connecting plate 9 causes it to compress the limiting spring 14. Rotating the hinge rod 18 causes the limiting plate 20 to rotate to the end of the connecting plate 9 closest to the outside, thus limiting the connecting plate 9 and preventing it from moving the limiting rod 12. The connecting frames 5 on both sides of the crossbeam 6 are placed at the top outside the support beam 1, with the support block 4 supporting the connecting frames 5. After placement, rotating the hinge rod 18 causes the limiting plate 20 to rotate downwards, moving it away from one end of the connecting plate 9. This allows the connecting plate 9 to lose its fixed position. The limiting spring 14, through its elasticity, causes the limiting rod 12 to embed inside the limiting groove 13, thus allowing... The connecting frame 5 is fixed to limit the movement of the crossbeam 6 outside the support beam 1. When the connecting plate 9 moves, the slider 15 will slide inside the slide groove 16. The slide groove 16 can limit the connecting plate 9 through the slider 15. The first fixing frame 2 is clamped outside the support beam 1 so that the fixing hole 8 on the first fixing frame 2 is aligned with the fixing hole 8 on the support beam 1. After the fixing hole 8 is aligned, the fixing bolt 3 is screwed into the fixing hole 8 to install and fix the first fixing frame 2. When the first fixing frame 2 is installed, the second fixing frame 7 is supported at the bottom outside the crossbeam 6. The second fixing frame 7 and the reinforcing rod 10 can support the crossbeam 6, increase the strength of the crossbeam 6 during use, and prevent the crossbeam 6 from bending and being damaged.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
