Description

Technical Field

[0001] This utility model relates to the field of safety fence technology, specifically a safety fence for construction projects. Background Technology

[0002] Safety is paramount during construction projects. Construction sites need to be clearly demarcated as hazardous areas to prevent unauthorized personnel from entering and to protect construction workers from potential safety threats. Safety fencing, as a common and important safety protection facility, is widely used on construction sites.

[0003] However, traditional safety fences used in construction still have certain shortcomings:

[0004] Construction sites are often affected by various external forces, such as wind, collisions with construction equipment and pedestrians. The support structure of many traditional fences is not stable enough and they are prone to tipping over when faced with these external forces, which cannot reliably guarantee construction safety. In order to fix them stably on the ground, crossbars are usually installed at the bottom of the two side posts. This setting makes it inconvenient to store and transport. Because of its fixed and large size, it requires a lot of storage space when not in use, and it also increases transportation costs and difficulties when it needs to be transported to a construction site.

[0005] Therefore, we propose a safety fence for construction projects to solve the problems mentioned above. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] The purpose of this utility model is to provide a safety fence for construction projects, so as to solve the problems currently found in the market as mentioned in the background.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, this utility model provides the following technical solution: a safety fence for construction engineering, comprising two side posts and a set of scissor-type telescopic frames. The two side posts are respectively arranged on the left and right sides of the scissor-type telescopic frames. Movable parts are installed on the upper part of the left and right sides of the scissor-type telescopic frames. The two movable parts are slidably installed on the left and right side posts respectively, and the movable parts are fixed on the side posts by fixing parts.

[0010] The front and rear sides of the lower end of the side column are fixed with a frame plate, and the frame plate is equipped with an auxiliary support. The upper end of the auxiliary support is connected to the lower end of the movable part. The movable part moves down to drive the auxiliary support to unfold, thereby expanding the support area of ​​the safety fence.

[0011] Furthermore, the movable component includes two movable plates, which are respectively disposed on the front and rear sides of the side column, and a movable rod is fixedly connected between the upper ends of the two movable plates, and a slider is fixed at the lower end of each of the two movable plates.

[0012] The above technical solution enables the movable plate, movable rod, and slider to move synchronously.

[0013] Furthermore, the scissor-type telescopic frame includes several first links and several second links, which are arranged in a scissor-like cross shape. The lower ends of the rightmost first link and the leftmost second link are rotatably connected to the left and right side columns, respectively. The upper ends of the leftmost first link and the rightmost second link are rotatably connected to the outside of the left and right movable rods, respectively.

[0014] The above technical solution enables the scissor-type telescopic frame to expand or retract when the movable rod moves up and down.

[0015] Furthermore, the slider is slidably mounted inside the frame plate.

[0016] The above technical solution ensures stable sliding of the moving parts.

[0017] Furthermore, the fastener includes a connecting screw, and also includes a connecting hole inside the movable plate and two through holes on the side of the side column. The connecting screw is threadedly connected to both the connecting hole and the through holes, and the two through holes are distributed vertically.

[0018] The above technical solution allows the movable part to be fixed on the side column after the connecting screw extends into the connecting hole and the through hole.

[0019] Furthermore, the auxiliary support includes a rotating rod rotatably mounted on the frame plate, and the auxiliary support also includes a support rod rotatably mounted in the middle of the slider, wherein the end of the rotating rod and the middle of the support rod are rotatably connected.

[0020] The above technical solution allows the support rod to rotate around the connection point with the slider after the slider moves down, under the action of the rotating rod, thereby expanding the support area of ​​the fence and improving its stability.

[0021] 3. Beneficial effects:

[0022] Compared with the prior art, the construction safety fence of this utility model, using the technical solution provided by this utility model, expands or retracts the scissor-type telescopic frame through the movement of movable parts for easy storage. Simultaneously, it expands the auxiliary support components, increasing the support area and improving stability. The specific details are as follows:

[0023] The scissor-type telescopic frame is composed of several first and second connecting rods. When the movable part moves on the side column, the connection between the movable part and the scissor-type telescopic frame drives the scissor-type telescopic frame to expand or contract, realizing the telescopic function of the safety fence. Thus, when the safety fence is not needed or is being transported, the area occupied by the safety fence can be reduced, so that the safety fence can be stored. When the movable part moves to the appropriate position, the connecting screw passes through the connecting hole and the through hole, and the movable part is fixed to the side column by the threaded connection, so that the safety fence is kept in the required telescopic state.

[0024] Furthermore, as the movable component moves downward, the slider moves downward as well, causing the support rod to rotate around its connection point with the slider. Simultaneously, the support rod causes the rotating rod to rotate around its connection point with the frame plate, thus unfolding the auxiliary support component. This ensures that the bottom of the support rod contacts the ground during use, expanding the support area of ​​the safety fence. A larger support area increases the fence's stability, allowing it to better withstand external forces such as wind and impacts during construction, effectively ensuring the safety of construction workers and those in the surrounding area. When the movable component moves upward, the auxiliary support component rotates in the opposite direction and retracts, further reducing its space occupation for easy storage.

[0035] Please see Figure 1-5A safety fence for construction projects includes two side posts 1 and a set of scissor-type telescopic frames 2. The two side posts 1 are respectively set on the left and right sides of the scissor-type telescopic frames 2. Movable parts 3 are installed on the upper part of the left and right sides of the scissor-type telescopic frames 2. The two movable parts 3 are slidably installed on the left and right side posts 1, and the movable parts 3 are fixed to the side posts 1 by fixing parts 4. The movable parts 3 include two movable plates 31, which are respectively set on the front and rear sides of the side posts 1. The upper ends of the two movable plates 31 are fixedly connected to a movable rod 32, and the lower ends of the two movable plates 31 are each fixed with a slider 33. The scissor-type telescopic frames 2 include a plurality of first connecting rods 21 and a plurality of second connecting rods 22. The rod 21 and several second connecting rods 22 form a scissor cross, and the lower end of the first connecting rod 21 on the far right and the lower end of the second connecting rod 22 on the far left are rotatably connected to the left and right side columns 1 respectively, and the upper end of the first connecting rod 21 on the far left and the upper end of the second connecting rod 22 on the far right are rotatably connected to the outside of the left and right movable rods 32 respectively; the slider 33 is slidably disposed inside the frame plate 5; the fixing member 4 includes a connecting screw 41, and the fixing member 4 also includes a connecting hole 42 opened inside the movable plate 31 and two through holes 43 opened on the side of the side column 1. The connecting screw 41 is threadedly connected to the connecting hole 42 and the through holes 43, and the two through holes 43 are distributed vertically;

[0036] When the movable part 3 moves on the side column 1, the upper end of the first connecting rod 21 on the far left and the upper end of the second connecting rod 22 on the far right are rotatably connected to the outside of the two movable rods 32 on the left and right respectively. The lower end of the first connecting rod 21 on the far right and the lower end of the second connecting rod 22 on the far left are rotatably connected to the two side columns 1 on the left and right respectively. Several first connecting rods 21 and second connecting rods 22 are cross-connected, which drives the scissor telescopic frame 2 to unfold or retract, realizing the telescopic function of the safety fence. Thus, when the safety fence is not needed or when the safety fence is not transported, the area occupied by the safety fence can be reduced so that the safety fence can be stored.

[0037] After the movable part 3 is moved to the appropriate position, the connecting screw 41 is passed through the connecting hole 42 and the through hole 43, and the movable part 3 is fixed to the side post 1 by means of threaded connection, so that the safety fence is kept in the required extension and retraction state.

[0038] The front and rear sides of the lower end of the side column 1 are fixed with frame plates 5, and auxiliary support members 6 are installed on the frame plates 5. The upper end of the auxiliary support member 6 is connected to the lower end of the movable member 3. The movable member 3 moves down to drive the auxiliary support member 6 to unfold, thereby expanding the support area of ​​the safety fence. The auxiliary support member 6 includes a rotating rod 61 rotatably installed on the frame plate 5, and the auxiliary support member 6 also includes a support rod 62 rotatably installed in the middle of the slider 33. The end of the rotating rod 61 and the middle of the support rod 62 are rotatably connected.

[0039] When movable part 3 moves downward, slider 33 moves downward accordingly, causing support rod 62 to rotate around its connection point with slider 33. Simultaneously, support rod 62 causes rotating rod 61 to rotate around its connection point with frame plate 5, thus unfolding auxiliary support part 6. During use, the bottom of support rod 62 contacts the ground, increasing the support area of ​​the safety fence. A larger support area increases the fence's stability, allowing it to better resist external forces such as wind and impacts during construction, effectively ensuring the safety of construction workers and those nearby. When movable part 3 moves upward, auxiliary support part 6 rotates in the opposite direction to retract, further reducing space occupation for easier storage.

[0040] Working principle: When using this construction safety fence, if... Figure 1-5 As shown, firstly, the connecting screw 41 is moved out of the upper through hole 43, and then the movable part 3 is moved downward. Using the connection between the movable part 3 and the scissor-type telescopic frame 2, the scissor-type telescopic frame 2 is unfolded. Then, the connecting screw 41 is rotated and inserted into the connecting hole 42 and the lower through hole 43 to fix the unfolded scissor-type telescopic frame 2. During the downward movement of the movable part 3, the auxiliary support 6 can be unfolded simultaneously to expand the support area of ​​the safety fence and improve stability. Then, the device is fixed in the required position using external fasteners. When it is not needed, the connecting screw 41 is removed again, and the operation is reversed to retract the scissor-type telescopic frame 2 and the auxiliary support 6, reducing the footprint of the safety fence for storage.
