Abstract
Description
Technical Field
[0001] This application belongs to the field of construction technology, specifically relating to a construction safety railing. Background Technology
[0002] Construction guardrails are an important safety feature at construction sites, road maintenance sites, and bridge construction sites. They are used to isolate construction areas and serve as warnings.
[0003] In the existing technology, the posts of the construction guardrail are fixed with connecting plates, and the fence is also equipped with connecting plates. The connecting plates on the fence and the connecting plates on the posts have through holes that are aligned with each other. When the fence is installed on the posts, the connecting plates on the fence and the connecting plates on the posts are aligned, and the threaded ends of the bolts are passed through the two connecting plates. Then, the fixing purpose is achieved by the cooperation of the nuts and bolts. During construction, the posts are first fixed on the ground, and then the fence is fixed to the posts with bolts and nuts.
[0004] However, at least two sets of connecting plates are required on the side where the fence connects to the post. The above-mentioned method of fixing with bolts and nuts is cumbersome and inefficient during installation. Utility Model Content
[0005] This application provides a construction safety barrier, which aims to solve the problem of low installation efficiency of construction safety barriers in the prior art.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A construction safety railing is provided, comprising a plurality of posts and a plurality of railings, wherein each railing and its corresponding post are provided with a plurality of sets of connection structures along the height direction, and each set of connection structures includes: A connector is attached to the column; the connector has a receiving groove that connects the top of the connector and the side of the connector facing away from the column. A plug-in component is connected to the side of the fence; the plug-in component is plugged into the receiving groove, and the side wall of the plug-in component contacts the inner side wall of the receiving groove; the side of the fence contacts the side of the connector. A limiting frame is slidably disposed on the connector; the limiting frame, the connector, and the plug-in component have mutually aligned through holes, and the limiting frame has a pin that engages with the through holes; before the plug-in component is plugged into the receiving groove, the limiting frame is located on the connector at a position that avoids the plug-in component.
[0007] In one possible implementation, one side of the limiting frame has a through hole that engages with a pin, and the other side of the limiting frame has a blind hole that engages with a pin. The limiting frame is connected to an elastic band on one side of the through hole. The two ends of the elastic band are fixed to the limiting frame and cover the through hole on the limiting frame. After the pin is inserted into the blind hole of the limiting frame, the other end of the pin protrudes out of the limiting frame and abuts against the inner side of the elastic band.
[0008] In one possible implementation, the outer side of the connector has a positioning component, and when the end of the limiting frame contacts the positioning component, the through hole on the limiting frame aligns with the through hole on the connector.
[0009] In one possible implementation, the positioning component has a countersunk hole, the connector has a threaded hole aligned with the countersunk hole, and the positioning component and the connector are fixed together by bolts.
[0010] In one possible implementation, the limiting frame is provided with a push hole at the position of the blind hole, and the diameter of the push hole is smaller than the diameter of the pin. When the push rod is inserted into the push hole and pushes the push shaft in the opposite direction, the elastic band avoids the through hole of the limiting frame.
[0011] In one possible implementation, the through holes on the limiting frame, the connector, and the plug-in component are horizontally arranged, the bottom of the plug-in component contacts the bottom of the receiving groove, and the top of the plug-in component contacts the limiting frame to limit the plug-in component in the height direction.
[0012] In one possible implementation, four connectors on the column are spaced circumferentially along the same horizontal plane.
[0013] In one possible implementation, a warning light is connected to the top of the post, and the warning light is electrically connected to a power source; reflective stickers are affixed to the fence.
[0014] In one possible implementation, the column is a multi-layered hollow structure, consisting of a carbon steel pipe, a galvanized layer, a rust-proof primer layer, and an epoxy paint layer from the inside out.
[0015] In one possible implementation, the fence includes a frame and several support rods disposed within the frame, spaced apart along the height direction.
[0016] This application provides a construction safety barrier. Compared with the prior art, after the posts are fixed to the ground, several plug-in components on the barrier are placed above the corresponding connectors on the posts, and then the barrier is lowered so that the plug-in components and the corresponding connectors are plugged in. At this time, the connectors can support the plug-in components, which facilitates the initial positioning of the barrier. The limiting frame is slid to a position aligned with the through hole of the connector, and is plugged in with the limiting frame, connector, and plug-in components through a pin. This can limit the position of the limiting frame and keep it in the position after sliding, thereby limiting the height of the plug-in components. With the above-mentioned settings of this application, compared with the bolt and nut fixing method in the prior art, this application can improve the installation efficiency.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0020] Please refer to the following: Figures 1 to 5This application describes a construction safety railing. The construction safety railing includes several posts 1 and several fences 2. Each fence 2 and its corresponding post 1 are connected along the height direction by several sets of connection structures 3. Each set of connection structures 3 includes a connector 31, a plug-in component 32, and a limiting frame 33. The connector 31 is connected to the post 1. The connector 31 has a receiving groove 311, which connects the top of the connector 31 and the side of the connector 31 facing away from the post 1. The plug-in component 32 is connected to the side of the fence 2. The insertion component 32 is inserted into the receiving groove 311, and the side wall of the insertion component 32 contacts the inner side wall of the receiving groove 311; the side of the fence 2 contacts the side of the connector 31; the limiting frame 33 is slidably disposed on the connector 31; there are through holes that are aligned with each other between the limiting frame 33, the connector 31 and the insertion component 32, and the limiting frame 33 has a pin 34 that is inserted into the through hole; before the insertion component 32 is inserted into the receiving groove 311, the limiting frame 33 is located on the connector 31 in a position that can avoid the insertion component 32.
[0021] This application provides a construction safety barrier. Compared with the prior art, after fixing the post 1 to the ground, several plug-in components 32 on the fence 2 are placed above the corresponding connectors 31 on the post 1, and then the fence 2 is lowered so that the plug-in components 32 are plugged into the corresponding connectors 31. At this time, the connectors 31 can support the plug-in components 32, which facilitates the initial positioning of the fence 2. The limiting frame 33 is slid to a position aligned with the through hole of the connector 31, and is plugged into the limiting frame 33, connectors 31 and plug-in components 32 through the pin 34. This can limit the position of the limiting frame 33, keep the limiting frame 33 in the slid position, and thus allow the limiting frame 33 to limit the height of the plug-in components 32. With the above-mentioned settings of this application, compared with the bolt and nut fixing method in the prior art, this application can improve the installation efficiency.
[0022] A mounting plate 5 is fixedly installed at the bottom of the column 1. The mounting plate 5 has through holes. The mounting plate 5 is fixed to the ground by anchor bolts. After the mounting plate 5 is fixed to the ground, the column 1 can be fixed to the ground.
[0023] Taking the example of setting three sets of connectors 31 on the column 1 in the height direction, each set of connectors 31 has four positions and is evenly distributed along the circumference of the column 1; through the above arrangement, the installation of the fence 2 at the turning position can be met.
[0024] Because the side of the fence 2 contacts the side of the connector 31, the fence 2 can be laterally limited, reducing the possibility of the fence 2 sliding towards the post 1. Through the contact between the side wall of the insertion component 32 and the inner side wall of the receiving groove 311, the insertion component 32 can be longitudinally limited, reducing the possibility of the fence 2 sliding along the tangent of the post 1. Through the insertion and engagement of the pin 34 with the limiting frame 33, the connector 31, and the insertion component 32, the insertion component 32 can be height-limited, reducing the possibility of the fence 2 sliding up and down. Therefore, through the above-described configuration of this application, the fence 2 can be limited in six directions (front, back, left, right, up, and down), ensuring the connection between the fence 2 and the post 1.
[0025] In some embodiments, such as Figure 1 As shown, one side of the limiting frame 33 has a through hole for insertion and engagement with the pin 34, and the other side of the limiting frame 33 has a blind hole for insertion and engagement with the pin 34; wherein, an elastic band 35 is connected to one side of the limiting frame 33 with the through hole, and both ends of the elastic band 35 are fixed to the limiting frame 33, and the elastic band 35 covers the through hole on the limiting frame 33; after the pin 34 is inserted and engaged with the blind hole of the limiting frame 33, the other end of the pin 34 protrudes out of the limiting frame 33 and abuts against the inner side of the elastic band 35.
[0026] After the pin 34 passes through one side of the limiting frame 33, the protruding end of the pin 34 is engaged with the connector 31 and the insertion component 32, and finally engaged with the blind hole of the limiting frame 33. Through the above settings, the situation of the pin 34 sliding too far can be avoided, and the insertion position of the pin 34 is limited.
[0027] Because an elastic band 35 is provided on the limiting frame 33, after the pin 34 is inserted into place, the inner side of the elastic band 35 abuts against the outer end of the pin 34, which enables the elastic band 35 to provide an inward clamping force on the pin 34, reducing the possibility of the pin 34 separating from the connector 31.
[0028] It should be noted that before the pin 34 is inserted into the limiting frame 33, the operator should first pull the elastic band 35 up or down at the through hole position to expose the through hole on the limiting frame 33, so that the end of the pin 34 can pass through the limiting frame 33. After the pin 34 is inserted into place, the outer end of the pin 34 protrudes from the limiting frame 33. At this time, the operator should return the elastic band 35 to its original position and make the inner side of the elastic band 35 cover the pin 34. This allows the elastic band 35 to provide axial clamping force on the pin 34, reducing the possibility of the pin 34 separating from the limiting frame 33.
[0029] After the pin 34 is inserted into the blind hole of the limiting frame 33, the elastic band 35 provides a clamping force to the other end of the pin 34. Through the above arrangement, the blind hole serves to prevent the pin 34 from disengaging from the other side of the limiting frame 33 and to limit the insertion position of the pin 34. The elastic band 35 serves to improve the connection between the pin 34 and the limiting frame 33 and, in conjunction with the blind hole, prevent the pin 34 from separating from the limiting frame 33.
[0030] In some embodiments, such as Figure 1 As shown, the outer side of the connector 31 has a positioning component 36. When the end of the limiting frame 33 contacts the positioning component 36, the through hole on the limiting frame 33 is aligned with the through hole on the connector 31.
[0031] The receiving groove 311 has an opening at the top of the connector 31. The opening is close to the side wall of the column 1 and forms a clearance space 37 between the opening and the column 1. Before the fence 2 is installed, the limiting frame 33 slides to the clearance space 37, which can avoid the opening at the top of the receiving groove 311.
[0032] When it is necessary to install the fence 2 onto the post 1, first place the plug-in part 32 on the fence 2 above the connector 31, and then slide the fence 2 down so that the plug-in part 32 is plugged into the receiving groove 311 on the connector 31.
[0033] Since the limiting frame 33 is in the clearance space 37, the limiting frame 33 will not interfere with the insertion process of the plug-in component 32 during the insertion process of the plug-in component 32 and the connector 31. When the plug-in component 32 is inserted into place, it can achieve the purpose of initially limiting the fence 2. At this time, the fence 2 can be kept on the post 1 and will not easily detach from the post 1.
[0034] Slide the limiting frame 33 toward the fence 2. When the end of the limiting frame 33 contacts the positioning component 36, it means that the limiting frame 33 has slid into place. At this time, the through hole on the limiting frame 33 is aligned with the through holes on the connector 31 and the plug-in component 32. After the pin 34 is plugged into the limiting frame 33, the connector 31 and the plug-in component 32, it can limit the position of the limiting frame 33 and keep the limiting frame 33 in the position after sliding.
[0035] In some embodiments, such as Figure 1 As shown, the positioning component 36 has a countersunk hole, and the connecting component 31 has a threaded hole aligned with the countersunk hole. The positioning component 36 and the connecting component 31 are fixed together by bolts.
[0036] During the production of post 1, connector 31 is welded onto post 1, then limit frame 33 is fitted onto connector 31, and finally positioning component 36 is fixed onto connector 31 with bolts. The above structure is completed at the factory, so it will not affect the efficiency of the installation process when installing fence 2.
[0037] The positioning component 36 and the connecting component 31 can be fixed by welding. After the column 1 is produced, the connecting component 31 is fixed on the column 1, and the positioning component 36 is fixed on the connecting component 31. During the installation of the fence 2, there is no need to operate the positioning component 36. That is, the positioning component 36 is only set for the production process of the column 1. During the installation of the fence 2, the positioning component 36 will not affect the efficiency of the installation of the fence 2.
[0038] In some embodiments, such as Figure 1 As shown, the limiting frame 33 is provided with a push hole 331 at the blind hole position. The diameter of the push hole 331 is smaller than the diameter of the pin 34. When the push rod is inserted into the push hole 331 and pushes the pin 34 in the opposite direction, the elastic band 35 avoids the through hole of the limiting frame 33.
[0039] When dismantling the fence 2, the operator first pulls the elastic band 35 upward or downward so that the elastic band 35 is located on one side of the pin 34. At this time, by pulling the outer end of the pin 34, the pin 34 can be pulled out from the limit frame 33.
[0040] When it is difficult to pull the pin 34, the push rod is inserted into the push hole 331 and the push rod abuts against the inner end of the pin 34. Then, the push rod is pushed axially to provide axial thrust to the pin 34, which makes it easier to push the pin 34 out of the limit frame 33.
[0041] Specifically, a disc can be fixedly installed on the outer end of the push rod to increase the contact area and make it easier for the operator to apply a pushing force to the disc, thereby pushing the pin 34 out of the limiting frame 33.
[0042] The two ends of the elastic band 35 are fixed to the limiting frame 33. The middle part of the elastic band 35 can deform, so the operator can pull the middle part of the elastic band 35 up and down to expose the middle part of the elastic band 35 through the through hole on the limiting frame 33. After the pin 34 is inserted into place, the elastic force of the elastic band 35 provides axial force to the pin 34, thereby strengthening the connection between the pin 34 and the limiting frame 33 and reducing the possibility of the pin 34 separating from the limiting frame 33.
[0043] In some embodiments, such as Figure 1As shown, the through holes on the limiting frame 33, the connector 31 and the plug-in component 32 are horizontally arranged. The bottom of the plug-in component 32 contacts the bottom of the receiving groove 311, and the top of the plug-in component 32 contacts the limiting frame 33, so as to limit the plug-in component 32 in the height direction.
[0044] By contacting the top of the limiting frame 33 with the plug-in component 32, the limiting frame 33 can play a height limiting role for the plug-in component 32 after it slides into place; at this time, the pin 34 is used to position the limiting frame 33 and reduce the force on the pin 34 in the height direction; through the above-mentioned settings of this application, the stability between the fence 2 and the post 1 can be improved.
[0045] The through holes on the limiting frame 33, the connector 31, and the plug-in component 32 are set horizontally. Compared with the vertical setting, the horizontal setting means that the pin 34 will not move in the height direction, which can improve stability.
[0046] In some embodiments, such as Figure 1 As shown, a warning light 4 is connected to the top of the column 1, and the warning light 4 is electrically connected to the power supply; reflective stickers are affixed to the fence 2.
[0047] The power source can be solar power, which is an existing technology and will not be described in detail here; the warning light 4 is an infrared warning light 4, which can automatically detect changes in the surrounding environment through infrared sensing. When a vehicle or pedestrian is detected, the infrared warning light 4 will light up and emit a warning light to remind people around to pay attention to the construction area and enhance safety; the infrared warning light 4 is an existing technology and will not be described in detail here.
[0048] Reflective stickers are installed on the front and back sides of fence 2. Reflective stickers are a type of material that can improve the visibility of objects at night or in low light conditions. They utilize the principle of retroreflection to reflect incident light back along its original path, making it easier for people to observe. Reflective stickers are existing technology and will not be described in detail here.
[0049] The application of this invention includes the installation of reflective stickers on fence 2, which improves the visibility of fence 2, thereby giving personnel sufficient time and space to take measures to slow down or avoid it.
[0050] In some embodiments, such as Figure 1 As shown, column 1 has a multi-layer hollow structure. From the inside out, column 1 consists of carbon steel pipe 11, galvanized layer 12, anti-rust primer layer 13, and epoxy paint layer 14.
[0051] By setting up a double protection of anti-rust primer layer 13 and epoxy paint layer 14, the rust resistance of the outside of the post 1 can be improved; the above-mentioned anti-rust primer layer 13 and epoxy paint layer 14 have ultraviolet reflective ability, thus enhancing the anti-aging performance of the outside of the post 1; anti-rust primer and epoxy paint can also be applied to the fence 2.
[0052] A top plate 16 is fixedly installed on the top of the column 1, and an mounting plate 5 is fixedly installed on the bottom of the column 1. The top plate 16 and the mounting plate 5 can close the top and bottom of the column 1. The warning light 4 is installed on the top plate 16.
[0053] In some embodiments, such as Figure 1 As shown, the fence 2 includes a fence frame 21 and support rods 22 disposed within the fence frame 21. There are several support rods 22, which are spaced apart along the height direction.
[0054] The fence frame 21 is rectangular, with a vertical bar 23 connected to the middle of the fence frame 21 and a horizontal bar 22 as the support bar. Through the above arrangement, the overall strength of the fence 2 can be improved.
[0055] It should be noted that the size of fence 2 can be selected according to actual needs, and the spacing between posts 1 is determined according to actual needs.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
