Description

Technical Field

[0001] This utility model relates to the technical field of protective railings for building construction, and in particular to a protective railing for building exterior wall construction. Background Technology

[0002] In recent years, with the rapid development of the construction industry, safety issues in high-altitude construction environments have become increasingly prominent. To ensure the safety of construction workers and the public, safety railings for building exterior walls are widely used as an important safety protection device. Their core function is to effectively prevent objects from falling, prevent worker injuries, and provide a stable support environment through scientifically designed structures and materials. At the same time, safety railings also possess aesthetic appeal and functionality, integrating seamlessly with the overall architectural style and enhancing the project's image.

[0003] During the construction of building exterior walls, existing guardrails are mostly fixed installations, making it difficult to adjust their height or width according to specific construction environments or design requirements. This inconvenience mainly stems from the relatively rigid structural design of existing guardrails, which cannot flexibly adapt to the needs of different scenarios.

[0004] In response to this technical problem, this application proposes a protective railing for the construction of building exterior walls. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction safety railing for building exterior walls. This railing flexibly adapts to different work surfaces, improves safety and construction efficiency, adapts to soft soil conditions, enhances safety, increases construction efficiency and material turnover, and significantly improves the pull-out stability of the main guardrail frame.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A construction safety railing for exterior walls includes a main railing frame, a wedge plate fixedly connected to the left end of the main railing frame, a docking shell fixedly connected to the right end of the main railing frame, a bottom plate fixedly connected to the bottom end of the main railing frame, a secondary railing frame connected to the inner wall of the main railing frame via a limiting component, a pressing plate slidably connected to the inner wall of the secondary railing frame, connecting shells fixedly connected to the bottom sides of both ends of the bottom plate, and rotating plates rotatably connected to the inner walls of both ends of the bottom plate, with insertion plates connected to the rotating plates via an installation component.

[0007] Furthermore, the limiting component includes a traction plate that rotates at both ends of the pressing plate, and a locking block is rotatably connected to one end of each traction plate opposite to the other.

[0008] Furthermore, rack plates are fixedly connected to both ends of the inner wall of the main guardrail, and the opposite end of the locking block is engaged with the opposite end of the rack plate.

[0009] Furthermore, each of the pressing plates is fixedly connected to a return spring at its top end, and the top end of the return spring is fixedly connected to the top end of the inner wall of the main guardrail frame.

[0010] Furthermore, the top of the docking shell is rotatably connected to a fixing bolt, and the bottom end of the fixing bolt is detachably connected to the top of the wedge plate.

[0011] Furthermore, the installation assembly includes a bidirectional screw fixedly connected to the bottom end of the rotating plate, the bottom end of the bidirectional screw being rotatably connected to the inner wall of the connecting shell, and a ground-breaking cone being fixedly connected to the bottom end of the connecting shell.

[0012] Furthermore, the upper and lower sides of the outer wall of the bidirectional screw are threaded with movable plates, and the opposite ends of the movable plates are rotatably connected with adapter plates.

[0013] Furthermore, each of the opposite ends of the bottom secondary guardrail frame is rotatably connected to a first insert plate, and the opposite ends of the second insert plate are rotatably connected to the outer wall of the top adapter plate. The outer walls of the second insert plate and the first insert plate are rotatably connected to the four sides of the outer wall of the connecting shell.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when widening the main guardrail frame is required during the construction of building exterior walls, the wedge-shaped plate is aligned with the connecting component, and the bolts are rotated and fixed to quickly complete the expansion. When adjusting the height, the pressing plate inside the secondary guardrail frame is pressed, causing the return spring to contract. This, through the traction plate, drives the locking block to disengage from the rack plate. After moving the secondary guardrail frame to the required height, it is released, and the locking block re-engages, achieving a stable limit. This design flexibly adapts to different working surfaces, improving safety and construction efficiency.

[0015] 2. In this utility model, during the construction of building exterior walls, to stabilize the main guardrail frame installed on the ground, the excavating cone and connecting shell are inserted into the soil as a whole. Rotating the rotating plate drives the bidirectional screw, which in turn moves the moving plate to unfold the adapter plate, forming a hook between the first and second insertion plates, significantly improving the pull-out stability of the main guardrail frame. Reverse rotation of the rotating plate can close the hook, facilitating damage-free recycling. This design is suitable for soft soil conditions, enhances safety, and improves construction efficiency and material turnover rate. Attached Figure Description

[0018] 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.

[0019] Reference Figure 1-3 This utility model provides an embodiment of a construction safety railing for building exterior walls, comprising a main railing frame 1, a wedge plate 4 fixedly connected to the left end of the main railing frame 1, a docking shell 2 fixedly connected to the right end of the main railing frame 1, a bottom plate 5 fixedly connected to the bottom end of the main railing frame 1, a secondary railing frame 8 connected to the inner wall of the main railing frame 1 via a limiting component, a pressing plate 10 slidably connected to the inner wall of the secondary railing frame 8, the limiting component including a traction plate 11 located at both ends of the pressing plate 10 and rotating, a locking block 12 rotatably connected to the opposite end of the traction plate 11, a rack plate 15 fixedly connected to both ends of the inner wall of the main railing frame 1, the opposite end of the locking block 12 engaging with the opposite end of the rack plate 15, a return spring 14 fixedly connected to the top of the pressing plate 10, the top of the return spring 14 fixedly connected to the top of the inner wall of the main railing frame 1, a 3 rotatably connected to the top of the docking shell 2, a fixing bolt 9 rotatably connected to the top of the 3, and the bottom end of the fixing bolt 9 detachably connected to the top of the wedge plate 4.

[0020] Specifically: During the construction of building exterior walls, when the guardrail system used needs to adapt to working surfaces or building protrusions of different widths, the main guardrail frame 1 can be flexibly widened. The specific method is as follows: precisely align another independent wedge plate 4 with the inner groove of the connecting member 3 already installed at the end of the main guardrail frame 1. Then rotate the connecting member 3 so that its sidewall fits tightly against the outer contour of the newly added wedge plate 4, forming a stable connection. At this time, tighten the fixing bolt 9 so that its threaded part is screwed into the corresponding pre-set screw hole of the wedge plate 4 and fully tightened. To ensure the safe and reliable expansion of the overall width of the guardrail and effectively meet the safety protection needs of different locations on the exterior wall, when the height of the construction floor changes or the guardrail protection height needs to be adjusted to adapt to the specific work location, the following steps can be taken: The operator located inside the sub-guardrail frame 8 presses the pressing plate 10 inside. This action overcomes the preload of the return spring 14, causing the return spring 14 to compress and deform. During the downward or inward displacement of the pressing plate 10, it will move together with the linkage plate 11 through a rigid connection such as a connecting rod or a slide. The movable plate 11 drives the connected locking block 12, forcing the locking block 12 to slide in a specific direction along the preset guide rail inside the secondary guardrail frame 8. This sliding action causes the locking block 12 to completely disengage from its original engaged locking position, i.e., from the toothed groove of the rack plate 15 fixed to the main guardrail frame 1 or standard section. Once the locking block 12 disengages from the rack plate 15, the secondary guardrail frame 8 is released from its vertical fixing constraint. At this time, the operator can adjust its height by pulling it up and down along the vertical guide rail of the main guardrail frame 1. After releasing the pressing plate 10... The compressed return spring 14 releases its elastic force, driving the pressing plate 10 to return to its original position upwards or outwards. This reset process synchronously drives the linkage plate 11 and the locking block 12 back to their original positions through the linkage mechanism, so that the locking block 12 automatically slides back under the action of the spring force and locks into the corresponding tooth groove of the rack plate 15 again, realizing the automatic locking of the adjusted height. At this time, the displacement of the secondary guardrail frame 8 is reliably limited. Thus, the adjustment of the working height required by the guardrail system is completed, ensuring that the height of the guardrail can accurately match the requirements of the current high-altitude operation conditions of the exterior wall construction.

[0021] Reference Figure 4 and Figure 5The bottom plate 5 has a connecting shell 6 fixedly connected to the bottom sides of both the left and right ends. The inner walls of both the left and right ends of the bottom plate 5 are rotatably connected to a rotating plate 7. The rotating plate 7 is connected to a second cutting plate 20 through an installation assembly. The installation assembly includes a bidirectional screw 16 fixedly connected to the bottom end of the rotating plate 7. The bottom end of the bidirectional screw 16 is rotatably connected to the inner wall of the connecting shell 6. The bottom end of the connecting shell 6 is fixedly connected to a ground-breaking cone 13. The upper and lower sides of the outer wall of the bidirectional screw 16 are threadedly connected to movable pieces 17. The opposite ends of the movable pieces 17 are rotatably connected to a transition plate 18. The opposite ends of the bottom auxiliary guardrail frame 8 are rotatably connected to a first cutting plate 19. The opposite ends of the second cutting plate 20 are rotatably connected to the outer wall of the top transition plate 18. The outer walls of the second cutting plate 20 and the first cutting plate 19 are rotatably connected to the four sides of the outer wall of the connecting shell 6.

[0022] Specifically: During the construction of the building's exterior walls, to enhance the stability of the main guardrail frame 1 installed on the ground, especially in backfill areas with loose soil, the bottom soil-breaking cone 13 and the connecting shell 6 encasing it are vertically inserted into the ground soil layer. Then, the rotating plate 7 above the connecting shell 6 is rotated. This operation drives the bidirectional screw 16, which meshes with the screw, to rotate. This causes the moving plates 17, threaded to both ends of the bidirectional screw 16, to move in opposite directions along the screw axis, thereby pushing the hinged adapter plate 18 outwards. Finally, the symmetrically arranged insert plates 19 and 20 open from the sides of the connecting shell 6 and embed themselves into the deep soil, forming a hook shape. The anchoring structure greatly enhances the pull-out resistance and overturning stability of the main guardrail frame 1 at the ground, ensuring the overall foundation of the high-altitude operation guardrail is solid. When the device needs to be retrieved after construction, the rotating plate 7 is rotated in the opposite direction, causing the bidirectional screw 16 to reverse and pull the moving plate 17 to move and retract in opposite directions. The linkage adapter plate 18 swings inward, completely closing the first insertion plate 19 and the second insertion plate 20 on the outer contour of the connecting shell 6, thereby eliminating soil resistance and facilitating the removal of the entire mechanism from the ground without damage for reuse. This design solves the problem of the difficulty of fixing traditional guardrails on non-hardened ground, and has the engineering advantages of efficient anchoring and convenient disassembly and assembly.

[0023] Working principle: When the main guardrail frame 1 is installed on the ground, the soil-breaking cone 13 and the connecting shell 6 are inserted into the soil as a whole. Then, the rotating plate 7 is rotated, which drives the bidirectional screw 16. The bidirectional screw 16 drives the two moving plates 17 to move. The moving plates 17 drive the adapter plate 18 to open the first insertion plate 19 and the second insertion plate 20 respectively, so that the second insertion plate 20 and the first insertion plate 19 form barbs, which improves the stability of the main guardrail frame 1 when it is installed on the ground. The rotating plate 7 rotates in the opposite direction, which closes the first insertion plate 19 and the second insertion plate 20 at the connecting shell 6, so as to recycle them. When the main guardrail frame 1 needs to be widened during use, another integral wedge plate 4 is connected to the inside of 3, and then 3 is rotated to fit against the wedge plate 4. The fixing bolt 9 is rotated to fix it to the wedge plate 4 through the thread, thus completing the overall widening. When the height needs to be adjusted, the pressing plate 10 inside the secondary guardrail frame 8 is pressed, causing the return spring 14 to contract. During the displacement process, the pressing plate 10 is pulled by the traction plate 11 to make the locking block 12 slide along the inner side of the secondary guardrail frame 8, and the locking block 12 is dislodged from the rack plate 15, so that the secondary guardrail frame 8 can move inside the main guardrail frame 1, thereby adjusting the height of the main guardrail frame 1. After releasing the pressing plate 10, the pressing plate 10 is reset and the locking block 12 is locked again at the rack plate 15, thus limiting the displacement of the secondary guardrail frame 8, thereby completing the height adjustment.
