Description

Technical Field

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

[0002] During construction, to ensure safety, protective railings are often installed at the edges of floors and along both sides of construction passages to prevent people or materials from falling accidentally.

[0003] Existing construction safety barriers are mostly fixed-length structures. Their working principle is to directly fix them in designated positions through pre-set installation components to form a protective barrier. However, in front-line work sites, fixed-length safety barriers are difficult to flexibly adapt to different protection distances. If the protection range is long, multiple barriers need to be spliced ​​together, which is not only cumbersome to operate, but may also affect the protective effect due to gaps at the splicing points. Secondly, the existing installation and fixing methods of protective railings are relatively simple, mostly relying on direct bolt fixing or heavy load ballast. Heavy load ballast on the outer edge of the building makes it difficult to form a firm connection, and it is easy to loosen due to external impact. Direct bolt connection will damage the original wall and pose a safety hazard. In order to solve the above problems, we propose a protective railing for building engineering. Utility Model Content

[0004] The main purpose of this utility model is to provide a protective railing for building construction, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A protective railing for construction projects includes a main protective railing body, a secondary protective railing body slidably connected to the inner side of the main protective railing body, and clamping components provided at opposite ends of both the main and secondary protective railing bodies. A limiting component is provided at the front end of the main protective railing body, the limiting component including a limiting outer shell, and the limiting outer shell being fixedly installed on the main protective railing. At the front end of the main body, a limiting post is slidably connected to the inner side of the limiting outer shell. Multiple limiting holes corresponding to the limiting posts are opened at the front end of the protective railing body, and one end of the limiting post is located inside the limiting hole.

[0006] Preferably, the clamping assembly includes an upper clamping plate, which is fixedly connected to the corresponding main guardrail body and secondary guardrail body. Two upright plates are fixedly connected to the lower end of the upper clamping plate, and a lower clamping plate is slidably connected between the two upright plates. Anti-slip grooves are provided at the adjacent ends of the upper clamping plate and the lower clamping plate.

[0007] Preferably, a bidirectional lead screw is rotatably connected between the two upright plates. One end of the bidirectional lead screw is provided with a drive motor. The drive motor is fixedly installed on the outside of one of the upright plates, and the output end of the drive motor is fixedly connected to the bidirectional lead screw. Threaded blocks are provided on both the forward and reverse threaded sections of the bidirectional lead screw. Rotating frames are rotatably connected to the outside of the two threaded blocks. A rotating seat is rotatably connected to the lower end of the rotating frame. The rotating seat is fixedly installed on the upper end of the lower clamping plate.

[0008] Preferably, both ends of the lower clamping plate are fixedly connected to guide rails, and the two adjacent ends of the upright plates are provided with guide grooves corresponding to the guide rails, and the guide rails are slidably connected to the inner side of the guide grooves.

[0009] Preferably, a mounting bracket is fixedly connected to the lower end of the main protective guardrail body, a gear is rotatably connected to the inner side of the mounting bracket, a rack is fixedly connected to the lower end of the secondary protective guardrail body, the gear meshes with the rack, a knob is fixedly connected to one end of the gear, and the knob is located on the outer side of the mounting bracket.

[0010] Preferably, the limiting component further includes a sliding plate, which is slidably connected to the inner side of the limiting housing. One end of the sliding plate is fixedly connected to a spring, and the other end of the spring is fixedly connected to the limiting housing. The spring is sleeved on the outer side of the limiting post, and one end of the limiting post is fixedly connected to a pull ring, which is located on the outer side of the limiting housing.

[0011] Preferably, one end of the limiting post has a slope, which is adapted to the limiting hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of protective railing for construction projects, when needing to adapt to different protection distances, drives the gear to rotate by turning the knob, and drives the rack to slide from the protective railing body relative to the main protective railing body. During the adjustment process, the limit post will automatically embed into the corresponding limit hole under the action of the spring to complete the fixation. There is no need to splice multiple railings, which simplifies the operation process and avoids the protection hazards caused by splicing gaps, effectively solving the problem that traditional fixed length railings are difficult to adapt to different protection distances.

[0013] 2. This type of protective railing for building construction uses a drive motor to rotate a bidirectional lead screw. The lower clamping plate and the upper clamping plate are driven by a threaded block and a rotating frame to achieve a stable clamping of the outer edge of the floor. It does not rely on bolt fixing or heavy loads, and it will not damage the wall structure. It can also form a firm connection in special scenarios such as the outer edge of the floor, reducing the risk of loosening caused by external force collisions and making it safer.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-6 As shown, a protective railing for a building project includes a main protective railing body 1, a secondary protective railing body 2 slidably connected to the inner side of the main protective railing body 1, and clamping components 3 provided at the ends of both the main protective railing body 1 and the secondary protective railing body 2 that are far apart from each other. A limiting component 4 is provided at the front end of the main protective railing body 1. The limiting component 4 includes a limiting shell 41, which is fixedly installed at the front end of the main protective railing body 1. A limiting post 44 is slidably connected to the inner side of the limiting shell 41. A plurality of limiting holes 5 corresponding to the limiting posts 44 are opened at the front end of the secondary protective railing body 2. One end of the limiting post 44 is located inside the limiting hole 5.

[0018] In this embodiment, the clamping assembly 3 includes an upper clamping plate 31, which is fixedly connected to the corresponding main guardrail body 1 and secondary guardrail body 2. Two upright plates 32 are fixedly connected to the lower end of the upper clamping plate 31, and a lower clamping plate 38 is slidably connected between the two upright plates 32. Anti-slip grooves are provided at the close ends of the upper clamping plate 31 and the lower clamping plate 38.

[0019] Specifically, by sliding the lower clamping plate 38, the upper clamping plate 31 can be used to clamp and fix the ground at the outer edge of the floor. The anti-slip grooves on the upper clamping plate 31 and the lower clamping plate 38 can enhance the stability of the clamping.

[0020] In this embodiment, a bidirectional lead screw 34 is rotatably connected between the two upright plates 32. A drive motor 33 is mounted at one end of the bidirectional lead screw 34. The drive motor 33 is fixedly installed on the outside of one of the upright plates 32. The output end of the drive motor 33 is fixedly connected to the bidirectional lead screw 34. Threaded blocks 35 are provided on both the forward and reverse threaded sections of the bidirectional lead screw 34. Rotating frames 36 are rotatably connected to the outer sides of the two threaded blocks 35. Rotating seats 37 are rotatably connected to the lower end of the rotating frames 36. Rotating seats 37 are fixedly installed on the upper end of the lower clamping plate 38. Guide rails 39 are fixedly connected to both ends of the lower clamping plate 38. Guide grooves 310 corresponding to guide rails 39 are opened at the close ends of the two vertical plates 32. The guide rails 39 are slidably connected to the inner side of the guide grooves 310.

[0021] Specifically, when installing and fixing this protective railing, the drive motor 33 can drive the bidirectional lead screw 34 to rotate, causing the two threaded blocks 35 to move in opposite directions on the bidirectional lead screw 34. Then, through the rotating frame 36 and the rotating seat 37, the lower clamping plate 38 can slide along the guide groove 310 on the inner side of the upright plate 32 and the guide rails 39 at both ends of the lower clamping plate 38. With the cooperation of the upper clamping plate 31, the ground at the outer edge of the floor can be clamped and fixed.

[0022] More specifically, the drive motor 33 in this solution is a device that can be purchased commercially by those skilled in the art. No structural modifications have been made to this device, and those skilled in the art are familiar with its working principle and can apply it proficiently based on their professional knowledge. Therefore, this paper will not elaborate further. Furthermore, this solution aims to protect the physical structure, not the circuitry or software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0023] In this embodiment, a mounting bracket 6 is fixedly connected to the lower end of the main protective guardrail body 1, a gear 8 is rotatably connected to the inner side of the mounting bracket 6, a rack 9 is fixedly connected to the lower end of the protective guardrail body 2, the gear 8 meshes with the rack 9, a knob 7 is fixedly connected to one end of the gear 8, and the knob 7 is located on the outer side of the mounting bracket 6.

[0024] Specifically, when using this protective railing to protect the outer edge of a floor plan, the user can adjust the length of the protective railing according to the required distance. During the adjustment process, turning the knob 7 can drive the gear 8 to rotate, which in turn drives the rack 9 to slide from the protective railing body 2 relative to the main protective railing body 1, thereby achieving the adjustment of the distance.

[0025] In this embodiment, the limiting component 4 further includes a sliding plate 42, which is slidably connected to the inner side of the limiting housing 41. One end of the sliding plate 42 is fixedly connected to a spring 43, and the other end of the spring 43 is fixedly connected to the limiting housing 41. The spring 43 is sleeved on the outer side of the limiting post 44. One end of the limiting post 44 is fixedly connected to a pull ring 46, which is located on the outer side of the limiting housing 41. One side end of the limiting post 44 has a slope 45, which is adapted to the limiting hole 5.

[0026] Specifically, after adjustment to the appropriate length, the limiting post 44 in the limiting component 4 is embedded in the limiting hole 5 corresponding to the front end of the guardrail body 2 under the elastic force of the spring 43, thereby fixing the guardrail body 2 by limiting it. The slope 45 at the end of the limiting post 44 facilitates the automatic retraction of the limiting post 44 during adjustment. Conversely, the limiting post 44 can be pulled out of the limiting hole 5 by pulling the pull ring 46 for readjustment.

[0027] It should be noted that this utility model is a protective railing for construction projects, and users should use it... When this protective railing protects the outer edge of a floor plan, its length can be adjusted according to the required distance. During adjustment, rotating the knob 7 drives the gear 8 to rotate, which in turn drives the sliding of the secondary railing body 2 relative to the main railing body 1 via the rack 9. When the appropriate length is reached, the limiting post 44 in the limiting component 4, under the elastic force of the spring 43, is embedded in the corresponding limiting hole 5 at the front end of the secondary railing body 2, thus fixing the secondary railing body 2. The slope 45 at the end of the limiting post 44 facilitates automatic retraction of the limiting post 44 during adjustment. Conversely, pulling the pull ring 46 can pull the limiting post 44 out of the limiting hole 5 for readjustment. When installing and fixing this protective railing, the drive motor 33 can drive the bidirectional lead screw 34 to rotate, causing the two threaded blocks 35 to move in opposite directions on the bidirectional lead screw 34. Then, through the rotating frame 36 and the rotating seat 37, the lower clamping plate 38 can slide along the guide groove 310 on the inner side of the upright plate 32 and the guide rails 39 at both ends of the lower clamping plate 38. With the cooperation of the upper clamping plate 31, the ground outside the floor can be clamped and fixed. The anti-slip grooves on the upper clamping plate 31 and the lower clamping plate 38 can enhance the stability of the clamping, which is quite practical.
