Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and in particular to a safety enclosure for building construction. Background Art

[0002] As Chinese residents have an urgent need to improve their living environment, the construction industry has unilaterally pursued scale development and neglected safety management, resulting in occasional safety accidents. Therefore, before construction, the construction area must be safely isolated, so fencing devices will inevitably be used to distinguish them. However, the existing safety fencing used in construction still has certain problems in actual use.

[0003] The document of the prior art publication number CN217269306U, a safety fence for construction, is provided. The device includes a stabilizing bracket located above the ground, a positioning rod inserted into the ground is penetrated on the upper surface of the stabilizing bracket, a protective baffle is fixedly installed on the upper surface of the stabilizing bracket, and a connecting column is fixedly installed on the left side of the protective baffle. The safety protection device for the construction road foundation pit drives the pressing rod and the sliding bracket to press and stabilize the protective baffle under the action of the force rod and the elastic force of the buffer spring column through the connecting plate and the pushing bracket, and has a better pressing and fixing effect on the protective baffle, effectively ensuring the stability of the support of the protective baffle, and can more comprehensively support the protective baffle, avoiding the situation that the protective baffle in the foundation pit falls, effectively ensuring the life safety of the construction personnel in the foundation pit, and is conducive to improving the construction safety.

[0004] The above-mentioned equipment drives the pressing rod and the sliding bracket through the connecting plate and the pushing bracket to press and stabilize the protective baffle under the action of the elastic force of the force-bearing rod and the buffer spring column, and has a better pressing and fixing effect on the protective baffle, effectively ensuring the stability of the support for the protective baffle, and can support the protective baffle more comprehensively. However, the guardrail of the equipment is installed in a fixed manner. When the surface of the guardrail is collided, it is difficult for the guardrail to offset the impact force by other means. This results in the guardrail and the fixed structures on both sides needing to absorb most of the impact force after being hit. If things go on like this for a long time, the equipment will inevitably be damaged, which requires the staff to improve the equipment first. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that a safety fence guardrail for construction is difficult to offset the impact force, thereby causing damage to the guardrail, thereby providing a safety fence for construction.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A support column, wherein the inner wall of the support column is slidably connected to a fixed block, the inner wall of the fixed block is rotatably connected to a first connecting block, the inner wall of the first connecting block is slidably connected to a connecting rod, the surface of the connecting rod is slidably connected to a second connecting block, rotation grooves are provided on both sides of the second connecting block, a spring is provided on one side of the inner wall of the first connecting block, and the other side of the spring is provided on the inner wall of the second connecting block, and a damping mechanism is provided inside the spring.

[0009] As an optional technical solution, sliding grooves are provided on both sides of the support column, and the surface of the fixed block is slidably connected to the inner wall of the sliding groove.

[0010] As an optional technical solution, a slot is provided on the inner wall of the support column, and the bottom of the fixing block overlaps the top of the slot.

[0011] As an optional technical solution, the inner wall of the rotating groove is rotatably connected with a connecting component, and the inner wall of the connecting component is provided with a guardrail.

[0012] As an optional technical solution, a top cover is provided on the top of the support column, and blocks are provided on both sides of the support column.

[0013] As an optional technical solution, two sides of the top cover are rotatably connected with rotating blocks, and a threaded sleeve rod is provided at the bottom of the rotating block.

[0014] As an optional technical solution, the inner wall of the threaded sleeve is threadedly connected with a fixing bolt, and a fixing plate is arranged at the bottom of the fixing bolt.

[0015] As an optional technical solution, a base is provided at the bottom of the support column, and limit blocks are provided on both sides of the surface of the connecting rod.

[0016] The utility model technical solution has the following advantages:

[0017] 1. The utility model connects the first connecting block and the second connecting block through a connecting rod, so that the structure can move in a small range. When the two sides of the guardrail are fixed at different heights, the structure can automatically level the guardrail, and the structures are connected by springs. When the guardrail is collided, the guardrail can shake slightly through the springs in the connecting structures on both sides, and the force of the collision is offset by shaking.

[0018] 2. The utility model can install two sets of guardrails on both sides of the support column through the slide grooves on both sides of the support column. By repeating this step, the equipment can be extended to the required length, so that the equipment can be applied to more construction sites, effectively improving the practicability of the equipment.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment 1:

[0031] like Figures 1 to 6 As shown, a safety fence for construction includes: a support column 1, the inner wall of the support column 1 is slidably connected with a fixed block 2, the inner wall of the fixed block 2 is rotatably connected with a first connecting block 3, the inner wall of the first connecting block 3 is slidably connected with a connecting rod 4, the surface of the connecting rod 4 is slidably connected with a second connecting block 5, rotation grooves 6 are provided on both sides of the second connecting block 5, a spring 7 is provided on one side of the inner wall of the first connecting block 3, and the other side of the spring 7 is provided on the inner wall of the second connecting block 5, a damping mechanism is provided inside the spring 7, a base 18 is provided at the bottom of the support column 1, and limit blocks 19 are provided on both sides of the surface of the connecting rod 4.

[0032] When the guardrail 11 is hit, the guardrail 11 drives the connecting components 10 on both sides to shake up and down in a small range. The shaking of the connecting components 10 drives the extended second connecting block 5 to shake. The connecting rod 4 sliding on the inner wall of the second connecting block 5 limits the second connecting block 5 and the first connecting block 3. When the second connecting block 5 shakes, it drives the connecting rod 4 and the first connecting block 3 to shake. When the connecting structure shakes, the two sides of the spring 7 arranged on the inner wall of the connecting rod 4 push the inner walls of the first connecting block 3 and the second connecting block 5 to reset them, and this process is repeated to consume the impact force and the force generated during the collision.

[0033] As an optional technical solution, slide grooves 8 are opened on both sides of the support column 1, and the surface of the fixed block 2 is slidably connected to the inner wall of the slide groove 8, the inner wall of the support column 1 is provided with a card groove 9, and the bottom of the fixed block 2 overlaps the top of the card groove 9.

[0034] When it is necessary to expand the protection range of the equipment, the fixed block 2 is slid into the slide groove 8. The four groups of fixed blocks 2 are of different sizes, and the volume gradually decreases from top to bottom. Each fixed block 2 is inserted into the slot 9 in turn when sliding, so as to fix the fixed block 2. In this way, multiple groups of support columns 1 are connected and fixed through the connection of the fixed blocks 2, thereby expanding the protection range of the guardrail 11.

[0035] As an optional technical solution, the inner wall of the rotating groove 6 is rotatably connected with a connecting component 10, the inner wall of the connecting component 10 is provided with a guardrail 11, the top of the support column 1 is provided with a top cover 12, and the two sides of the support column 1 are provided with clamping blocks 13, the two sides of the top cover 12 are rotatably connected with rotating blocks 14, the bottom of the rotating block 14 is provided with a threaded sleeve 15, the inner wall of the threaded sleeve 15 is threadedly connected with a fixing bolt 16, and the bottom of the fixing bolt 16 is provided with a fixing plate 17.

[0036] After installing the guardrail 11, place the top cover 12 on the top of the support column 1, rotate the rotating block 14, place the fixing plate 17 at the bottom of the fixing bolt 16 to the bottom of the clamping block 13, and then rotate the fixing bolt 16. The fixing bolt 16 rotates on the inner wall of the threaded sleeve 15, so that the fixing bolt 16 is retracted into the threaded sleeve 15. The rise of the fixing bolt 16 drives the fixing plate 17 to rise, so that it is clamped at the bottom of the clamping block 13, thereby fixing the top cover 12.

[0037] Embodiment 2:

[0038] The above Figures 1 to 6 As shown, a safety fence for building construction includes:

[0039] When the guardrail 11 is hit, the guardrail 11 drives the connecting components 10 on both sides to vibrate up and down in a small range. The shaking of the connecting components 10 drives the extended second connecting block 5 to vibrate. The connecting rod 4 sliding on the inner wall of the second connecting block 5 limits the second connecting block 5 and the first connecting block 3. When the second connecting block 5 vibrates, it drives the connecting rod 4 and the first connecting block 3 to vibrate. When the connecting structure vibrates, the two sides of the spring 7 arranged on the inner wall of the connecting rod 4 push the inner walls of the first connecting block 3 and the second connecting block 5 to reset them. This is repeated to consume the impact force and the force generated by the collision. When it is necessary to expand the protection range of the equipment, the fixed block 2 is slid into the slide groove 8. The four groups of fixed blocks 2 are of different sizes. The volume gradually decreases from top to bottom, and each fixing block 2 is sequentially inserted into the card slot 9 when sliding, thereby fixing the fixing block 2. In this way, multiple groups of support columns 1 are connected and fixed through the connection of the fixing blocks 2, thereby expanding the protection range of the guardrail 11. After installing the guardrail 11, the top cover 12 is placed on the top of the support column 1, and the rotating block 14 is rotated to place the fixing plate 17 at the bottom of the fixing bolt 16 to the bottom of the card block 13, and then the fixing bolt 16 is rotated. The fixing bolt 16 is rotated on the inner wall of the threaded sleeve rod 15, so that the fixing bolt 16 is retracted into the threaded sleeve rod 15, and the rise of the fixing bolt 16 drives the fixing plate 17 to rise, so that it is stuck at the bottom of the card block 13, thereby fixing the top cover 12.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the utility model creation.
