Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a connection structure for a building construction safety railing. Background Technology

[0002] During construction, numerous safety hazards exist at construction sites, such as falls from heights and being struck by falling objects. Guardrails, as an important safety protection facility, effectively isolate dangerous areas, prevent personnel from accidentally entering them, and protect the lives and health of construction workers. They are also a crucial component of construction site safety management.

[0003] Chinese patent application number 202421606084.9 discloses a connection structure for construction safety railings, including a first set of posts and a second set of posts. The inner wall of the first set of posts is fixedly connected to the left safety railing post, and the inner wall of the second set of posts is fixedly connected to the right safety railing post. The structure also includes a connecting component located on one side of the first set of posts and fixedly connected to the side wall of the first set of posts, and an adjusting component located on one side of the second set of posts and fixedly connected to the side wall of the second set of posts. The connecting component includes a first connecting block located on one side of the first set of posts. This invention, by setting a connecting component, allows the two safety railings to be connected or disassembled, facilitating installation as needed. The adjusting component allows adjustment of the angle between the two safety railings, enabling placement in different positions and increasing the ease of use.

[0004] Although the aforementioned patent enables the connection and use of construction safety railings, the connection structure between the longitudinal guardrails has poor fixing effect, and it is inconvenient to adjust the angle between the longitudinal guardrails after fixing; the fixing effect between the longitudinal guardrails and the transverse guardrails is also poor, and it is inconvenient to disassemble them. After the guardrails are damaged, it is inconvenient to disassemble and repair them separately. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a connection structure for construction safety railings, which features better connection between longitudinal railings and better fixation between longitudinal and transverse railings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction safety railing connection structure, comprising a longitudinal safety railing one, a transverse safety railing one on the side of the longitudinal safety railing one, a longitudinal safety railing two at the other end of the transverse safety railing one, a longitudinal safety railing three on the side of the longitudinal safety railing two, a transverse safety railing two on the side of the longitudinal safety railing three, a longitudinal safety railing four at the other end of the transverse safety railing two, the longitudinal safety railing two and the longitudinal safety railing three being connected by a longitudinal safety railing connection mechanism, and the longitudinal safety railing one and the transverse safety railing one being fixedly connected by a transverse and longitudinal safety railing connection mechanism.

[0007] Preferably, the longitudinal guardrail connecting mechanism includes a bolt, a strip plate, an angle adjustment assembly, a rotating block, a rotating block, and a strip slot. Angle adjustment assemblies are provided on the sides of both the second and third longitudinal guardrails.

The rotating block is internally connected to the T-shaped insert, and the rotating block is internally provided with a T-shaped slot corresponding to the T-shaped insert. The strip plate is internally provided with a square hole corresponding to the T-shaped insert.

[0009] Preferably, the angle adjustment assembly includes a fastening nut, a rotating shaft, and a U-shaped plate. The sides of both the second and third longitudinal guardrails are fixed with U-shaped plates. The second rotating block is rotatably connected to the U-shaped plate via a rotating shaft. A set of rotating shafts are threaded with fastening nuts on their surfaces.

[0010] Preferably, the horizontal and vertical guardrail connecting mechanism includes two bolts, a support component, two square holes, two T-slots, and two T-blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates a longitudinal guardrail connection mechanism with an optimized bolt connection design, enabling rapid installation and stable connection between guardrail posts. Compared to traditional welding methods, bolt connections eliminate the need for on-site welding equipment, avoiding safety hazards and thermal damage to materials during welding. Furthermore, the bolt connection method allows for quick disassembly and reuse according to construction needs, significantly improving construction efficiency and material utilization. In addition, the uniform distribution of bolt tightening force effectively resists longitudinal external impacts, ensuring the vertical stability of the guardrail and providing reliable protection for construction workers.

[0014] 2. This utility model incorporates a horizontal and vertical guardrail connection mechanism. This mechanism, through bolt connections, achieves a tight fit between the horizontal and vertical guardrails, enhancing the overall structural strength and stability of the guardrail. The bolt connection method is not only easy to operate but also allows for flexible adjustment of the guardrail's layout and angle according to the actual needs of the construction site, improving the guardrail's versatility and adaptability. Furthermore, the bolt tightening force can be adjusted according to actual needs, ensuring the connection's firmness and effectively preventing the guardrail from loosening or deforming due to external impacts, further enhancing the safety of the construction site.
