[0002] Frame beams, also known as grid beams, include anchored frame beams and cable-stayed frame beams. The grid of a frame beam consists of horizontal and vertical beams forming a square grid. They are used in the construction of highways in mountainous areas and are installed on landslide bodies such as road cut slopes to enhance the slope's resistance to erosion, improve the stability of the landslide body, and constrain slope deformation. The construction of frame beams involves processes such as foundation excavation, frame beam reinforcement fabrication and installation, frame beam formwork installation, frame beam concrete pouring, curing, and formwork removal. Alternatively, they can be prefabricated in a factory and then transported to the construction site for assembly.

[0003] When reinforcing slopes, frame beams are generally used. To improve construction speed, the frame beams are prefabricated and then assembled on site. In the prefabricated frame beam assembly technology, the slots on one side of one set of frame beams are connected to the blocks on the other side of another set of frame beams, and then bolts are used to lock them.

Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0045] like Figure 1-9 As shown in the figure, this application embodiment provides a prefabricated frame beam structure that can be assembled quickly. This prefabricated frame beam structure has the characteristics of simple and quick assembly, significantly improved assembly efficiency, and comprehensive functions. The prefabricated frame beam structure in this embodiment includes a frame beam structure body, which is fixedly installed on the outer surface of slope 1. Slope 1 is a slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. Because slope 1 has a certain slope, the slope surface of slope 1 will be damaged when encountering heavy rainfall. In order to prevent this from happening, frame beams 2 are generally installed on slope 1 to block the erosion of rainwater.

[0046] Specifically, the frame beam structure includes multiple frame beams 2, positioning columns 24, locking blocks 25, self-locking devices 3, and anchor bolts 4. Each frame beam 2 includes multiple first beams 21 extending along a first direction, spaced apart from adjacent beams 21, and multiple second beams 22 extending along a second direction, also spaced apart. The first beams 21 and second beams 22 are integrally formed. Anchor bolt holes 23 are provided at at least some of the junctions between the first beams 21 and second beams 22. The anchor bolts 4 pass through the anchor bolt holes 23 and extend into the slope 1, as shown in the figure. In this text, the second direction is perpendicular to the first direction. To increase structural stability, reinforcing ribs are also provided at the connections between the first beams 21 and second beams 22.

[0047] like Figure 1-3 As shown, the first beam 21 and the second beam 22 are arranged in a crisscross pattern. During installation, the first beam 21 is the horizontal beam of the frame beam 2, and the second beam 22 is the vertical beam of the frame beam 2. It should also be noted that the first beam 21 and the second beam 22 can be determined according to actual needs, so this article does not make specific limitations. In this embodiment, there are two first beams 21 and two beams 22 in a single frame beam 2, and multiple frame beams 2 are combined to form the frame beam structure body.

[0048] In addition, the positioning post 24 is located at one end of the first beam 21 and the second beam 22 along the length direction, and the height direction of the positioning post 24 extends to a predetermined depth along the thickness direction of the frame beam 2; the locking block 25 is located at the other end of the first beam 21 and the second beam 22 along the length direction, and the locking block 25 has a limiting hole. The locking block 25 is sleeved on the positioning post 24 through the limiting hole, and two adjacent frame beams 2 are connected by the positioning post 24 and the locking block 25; the self-locking device 3 is located on the upper part of the positioning post 24, and the self-locking device 3 can restrict the relative movement of the positioning post 24 and the locking block 25 after the locking block 25 is sleeved on the positioning post 24.

[0049] like Figure 4 As shown, in this embodiment, a stepped surface is provided at one end of the first beam 21 and the second beam 22 along the length direction. The positioning post 24 is integrally set on this stepped surface. When the locking block 25 of another frame beam 2 cooperates with the positioning post 24 on the stepped surface, the two connected frame beams 2 are basically flush, so they can be fixed by the self-locking device 3 to complete the installation. This connection method is stable and reliable and the assembly is faster, thereby greatly improving the overall assembly efficiency of the frame beams 2 and speeding up the construction progress.

[0050] like Figure 4-5 and Figure 9As shown, in one specific embodiment, the self-locking device 3 includes a beveled block 31 and a first spring 32. The beveled block 31 includes a first block 311 and a second block 312 arranged symmetrically. The sides of the first block 311 and the second block 312 that are opposite to each other have a sloping surface. The first spring 32 is disposed between the first block 311 and the second block 312. After the locking block 25 reaches the preset installation position, the sides of the first block 311 and the second block 312 relative to the locking block 25 are engaged with the locking block 25. A through groove is provided on the upper part of the positioning post 24, and the first block 311 and the second block 312 are installed in the installation groove.

[0051] In addition, the self-locking device 3 also includes a disassembly mechanism, which can press the first block 311 and the second block 312 to release the restriction of the first block 311 and the second block 312 on the locking block 25. The disassembly mechanism includes a connecting rod 33 and a rotating shell 34. The connecting rod 33 is fixedly disposed on the top of the first block 311 and the second block 312. The rotating shell 34 is movably sleeved on the circumferential outer wall of the connecting rod 33. The rotating shell 34 can rotate relative to the positioning post 24 and intermittently press the connecting rod 33. The top of the positioning post 24 is provided with a limiting block 35. The rotating shell 34 is movably connected to the positioning post 24 through the limiting block 35. The inner wall of the rotating shell 34 is provided with an elliptical groove 36. The short axis side of the elliptical groove 36 is provided with an outwardly extending locking groove 37.

[0052] When assembling the multiple frame beams 2 in this embodiment, the positioning post 24 at one end of one frame beam 2 is first connected to the locking block 25 at one end of another frame beam 2. When the outer slope surfaces of the first block 311 and the second block 312 on the positioning post 24 are compressed, relative movement occurs, that is, the first block 311 and the second block 312 will retract inward, and the first spring 32 will be compressed. After the locking block 25 reaches the preset installation position, the locking block 25 disengages from the first block 311 and the second block 312, and the first spring 32 resets, causing the first block 311 and the second block to unfold outward, thereby engaging the locking block 253, thus completing the assembly and fixation between the two frame beams 2.

[0053] When some frame beams 2 are damaged and cannot be used anymore and need to be replaced, the rotating shell 34 is rotated. The narrow arc surface inside the rotating shell 34 squeezes the connecting rod 33. The connecting rod 33 is squeezed inward and moves relative to the connecting rod, thereby driving the first block 311 and the second block to move. The movement of the inclined block 31 squeezes the first spring 32 and causes it to contract. When the two sets of connecting rods 33 contact the slot 37 inside the rotating shell 34, the connecting rods 33 and the rotating shell 34 are engaged. At this time, the first block 311 and the second block 312 retract, and the damaged frame beam 2 can be taken out and replaced. In this way, the prefabricated assembled frame beam 2 can be quickly assembled, which can speed up the construction efficiency of the slope 1 reinforcement project and enable the slope 1 to be put into use as soon as possible.

[0054] like Figure 2 and Figure 6-7 As shown, in one specific embodiment, the cross-sectional shape of the anchor bolt 4 hole 23 is an inverted trapezoid. A locking block 5 is provided inside the anchor bolt 4 hole 23. The locking block 5 has an internally threaded hole extending through it along the thickness direction. The upper part of the anchor bolt 4 is provided with an external thread, and the anchor bolt 4 is threadedly connected to the locking block 5. A hook 41 is provided at the end of the anchor bolt 4 away from the slope 1. The hook 41 is movably connected to the anchor bolt 4 through a telescopic mechanism. The telescopic mechanism can drive the hook 41 to move along the length direction of the anchor bolt 4, so as to retract into the anchor bolt 4 or protrude from the anchor bolt 4.

[0055] In addition, the telescopic mechanism includes a second spring 42, a first connecting block 43 and a second connecting block 44, and a hook 41 is disposed at the end of the second connecting block 44; the end of the anchor rod 4 is provided with an installation groove, and the second spring 42, the first connecting block 43 and the second connecting block 44 are sequentially disposed in the installation groove. The second connecting block 44 is rotatably connected to the first connecting block 43. The side wall of the second connecting block 44 is provided with a sliding block 45. The inner wall of the installation groove is provided with a vertical groove 46 and a horizontal groove 47. The sliding block 45 can slide along the vertical groove 46 and be locked in the horizontal groove 47.

[0056] When installing the frame beam 2, the anchor rod 4 needs to be pre-installed in the slope 1 first, and then the frame beam 2 is installed on the anchor rod 4. After the anchor rod 4 is connected to the frame beam 2, the locking block 5 is threaded to the anchor rod 4. When the anchor rod 4 contacts the tapered groove inside the frame beam 2, the connection between the frame beam 2 and the anchor rod 4 is completed, and the frame beam 2 will be unable to move. After slope 1 is laid, soil needs to be filled into the frame beam 2 and vegetation planted. To prevent the newly planted vegetation from being washed away by rainwater, a net needs to be installed for protection. By rotating the moving hook 41, the hook 41 drives the second connecting block 44 to rotate. The rotation of the second connecting block 44 drives the sliding block 45 to rotate inside the transverse groove 47. When the sliding block 45 disengages from the transverse groove 47, the second spring 42 resets, driving the first connecting block 43 to move. At this time, the sliding block 45 contacts the vertical groove 46, and the first connecting block 43 can move. After moving a certain distance, the sliding block 45 limits the second connecting block 44. At this time, the hook 41 disengages from the inside of the anchor rod 4, and the net can be hung on the hook 41 to protect the slope 1.

[0057] When the netting is not needed, the second connecting block 44 can be pushed to compress the second spring 42 to retract. When the second connecting block 44 cannot move, the second connecting block 44 can be rotated to drive the sliding block 45 into the transverse groove 47. At this time, the hook 41 can be stored inside the anchor rod 4 to prevent it from being damaged. In this way, the hook 41 of the prefabricated frame beam structure can be used to install the netting on the surface of the slope 1 to prevent the newly planted vegetation from being washed away by rainwater.

[0058] like Figure 1-3 and Figure 8 As shown, in one specific embodiment, the frame beam 2 further includes multiple drainage holes 6, which are located on the first beam 21 and / or the second beam 22. Drainage pipes 7 are installed within the drainage holes 6, and filter units are installed within the drainage pipes 7. The drainage pipes 7 are detachably connected to the drainage holes 6 via a limiting mechanism. The upper part of the drainage pipe 7 has a funnel-shaped structure. The filter unit includes a non-woven permeable geotextile 71, a wire mesh 72, and a sand and gravel layer 73. The non-woven permeable geotextile 71 is located at both ends of the drainage pipe 7, and two wire meshes 72 are installed between the two non-woven permeable geotextiles 71. The sand and gravel layer 73 is located between the two wire meshes 72.

[0059] In addition, the limiting mechanism includes a fixing block 74, a locking rod 75, a third spring 76, and a protective cover 77; the fixing block 74 is disposed on the outer wall of the drain pipe 7, the locking rod 75 is movably disposed in the drain hole 6, the locking rod 75 can rotate at a preset angle along the connection point to limit the fixing block 74, and the third spring 76 abuts against the locking rod 75 and the inner wall of the drain hole 6; one end of the protective cover 77 is hinged to the first beam 21 and / or the second beam 22, and the other end of the protective cover 77 is connected to the first beam 21 and / or the second beam 22 through a protrusion 78, the protrusion 78 being made of rubber.

[0060] During heavy rainfall, rainwater accumulates in the frame beams 2. If it cannot be drained in time, it will affect the structural strength of the slope 1. Due to the slope of the slope 1, the rainwater flows with the slope. Therefore, setting multiple drainage holes 6 along the slope to connect adjacent frame beams 2 can effectively drain the rainwater and prevent its accumulation. The filter unit in the drainage pipe 7 can prevent silt from entering the drainage pipe 7 with the rainwater. When the rainwater comes into contact with the non-woven permeable geotextile 71, it enters the interior of the drainage pipe 7. Under the barrier and filtration of the non-woven permeable geotextile 71, wire mesh 72, and sand and gravel layer 73, the silt in the rainwater is filtered out, preventing it from entering the drainage pipe 7 and clogging it. The rainwater is discharged through multiple drainage pipes 7, preventing a large amount of rainwater from accumulating in the frame beams 2.

[0061] When the filter unit inside the drainage pipe 7 is damaged, it needs to be replaced to ensure the drainage effect of the prefabricated frame beam structure. By rotating the protective cover 77, the protrusion 78 is moved, causing it to deform and detach from the frame beam 2, thus opening the protective cover 77. At this time, the locking rod 75 can be rotated, compressing the third spring 76 and causing it to disengage from the fixing block 74. The drainage pipe 7 can then be removed for replacement. The protective cover 77 prevents soil from entering the interior of the frame beam 2. The detachable design of the drainage pipe 7 and the filter unit allow for drainage of the frame beam structure, preventing rainwater from accumulating in the prefabricated frame beam structure and damaging the slope 1 structure.

[0062] In summary, when assembling the prefabricated frame beam structure onto slope 1, slope 1 is first leveled, then the installation holes for anchor rods 4 are drilled on slope 1, and the anchor rods 4 are installed into the installation holes. After installation, the prefabricated frame beams 2 are connected to the anchor rods 4. After connection, multiple sets of frame beams 2 are assembled. After assembly, soil is filled into the frame beams 2, and grass seeds are sown to reinforce slope 1, thus completing the assembly of the prefabricated frame beams 2. The entire prefabricated frame beam structure not only satisfies the requirements of quick assembly and improved construction efficiency, but also possesses rich functionality. These additional functions, such as the setting of hooks 41 and drainage pipes 7, are all detachable and replaceable, which increases the lifespan of the prefabricated frame beam structure while reducing future maintenance costs.

[0063] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
