Description

Technical Field

[0001] This utility model belongs to the field of external wall protection railing technology, and more specifically, it relates to an external wall protection railing reinforcement device. Background Technology

[0002] Existing exterior wall guardrails are mostly fixed directly to the wall with expansion bolts. Over time, they are susceptible to aging of the connectors due to wind and rain erosion, temperature changes, and external impacts. Some older building guardrails lack additional reinforcement structures, resulting in insufficient stability after installation and a risk of detachment, jeopardizing personnel safety. Furthermore, traditional reinforcement methods are often localized repairs, lacking adaptability and being complex to implement, failing to fundamentally improve the overall load-bearing capacity of the guardrails.

[0003] Patent CN221761167U discloses a reinforcement device for exterior wall guardrails, including a wall post and a guardrail body detachably connected to the wall post. The guardrail body includes a horizontal bar, one end of which is fitted with an mounting plate. The mounting plate has mounting holes for inserting fixing bolts. A protective structure is provided on the horizontal bar to protect the fixing bolts. The protective structure includes two protective shells movably fitted onto the horizontal bar, each shell having two connecting rods. While the above patent solves the problem of a stable connection between the wall post and the guardrail, it only addresses the connection between the two sides of the guardrail and the wall post. The connection between the middle and the edge of the guardrail is relatively far, making it susceptible to movement under external force or strong winds. This movement can then affect the sides, potentially damaging the guardrail.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an external wall guardrail reinforcement device. Through the extension and retraction of the telescopic rod, it can adapt to the guardrail with different column spacing for reinforcement work. Moreover, it adopts a multi-point fixing form to reinforce the entire guardrail, making it more stable and solid.

[0006] The aforementioned external wall guardrail reinforcement device includes a concrete wall, which includes two columns and a guardrail fixed to the concrete wall. The guardrail has fixing mechanisms on both sides of the columns. Each fixing mechanism includes a central turntable, which is hollow in the middle. Four equidistant rotating shafts are fixedly connected to the hollow center. Connecting rods are rotatably connected to the rotating shafts. One end of each connecting rod has a hole for rotatable connection to the rotating shaft, and the other end has a groove. A telescopic rod is slidably connected within the groove. A spring is fixedly connected to one end of the telescopic rod, with one end of the spring abutting against the bottom of the groove. A cylinder is fixedly connected to one side of the other end of the telescopic rod, and a fixed bracket is slidably connected to the outside of the cylinder.

[0007] Preferably, multiple fixing plates are fixedly connected at equal intervals on both sides of the fixed bracket, and fixing bolts are screwed onto the fixing plates. The fixing bolts are screwed onto the column. The fixed bracket has a long groove in the length direction to facilitate the sliding of the cylinder, and multiple limiters are equidistantly provided on the outer side of the long groove.

[0008] Preferably, the internal space of the long groove is larger than the space at the opening, and the diameter of the end of the cylinder near the telescopic rod is the same as the distance at the opening of the long groove.

[0009] Preferably, the connecting rod is slidably connected to a slide frame, and a threaded post one is fixedly connected to one end of the slide frame near the guardrail. A threaded tube is screwed onto the outside of the threaded post one, and a rod is fixedly connected to the outside of the threaded tube. A threaded post two is screwed onto one end of the threaded tube. A fastening platform is fixedly connected to one end of the threaded post two, and the fastening platform abuts against the guardrail.

[0010] Preferably, the fastening platform is made of rubber material.

[0011] Preferably, two spliced ​​central fixing frames are fixedly connected to the middle pole of the guardrail. The central fixing frame includes a clamping frame around the middle pole of the guardrail. The clamping frame has a concave structure. At both ends of the protruding part of the clamping frame, a convex rail is fixedly connected to one end, and a groove is opened at the other end. The two clamping frames are connected in opposite directions and are clamped around the outer perimeter of the middle pole of the guardrail. A long column is fixedly connected to one side of the clamping frame. One end of the long column has two threaded holes.

[0012] Preferably, a threaded hole is provided at the geometric center of the central turntable.

[0013] Preferably, a long bolt is screwed into the first threaded hole, and the long bolt is screwed into the second threaded hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets a fixing mechanism on both sides of the traditional guardrail. The fixing mechanism is connected to the column. The sliding bracket is slidably connected to the connecting rod on both sides of the guardrail. After adjusting the position, the threaded tube is rotated to bring the fastening platform close to the guardrail and abut against the guardrail. The long bolt is used to screw the central fixing bracket nested in the middle of the guardrail through the central turntable in the middle of the fixing mechanism, so that the guardrail and the fixing are integrated into a whole, greatly increasing the firmness.

[0015] 2. The connecting rod of this utility model has a telescopic rod that slides inside. The reason for this design is that the distance between the two columns of different buildings is different. By extending and retracting the telescopic rod, it can be fixed to accommodate different column distances. A spring is set at one end of the telescopic rod so that the telescopic rod can abut against the limit on the fixed bracket. This can prevent the telescopic rod from moving after the length of the telescopic rod is adjusted. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figures 1 to 6 As shown, an external wall guardrail reinforcement device includes a concrete wall 1, which includes two posts 102 and a guardrail 101 fixed to the concrete wall 1. The guardrail 101 has fixing mechanisms 2 on both sides, which are fixed to the posts 102. Figures 2 to 3As shown, the fixing mechanism 2 includes a central turntable 202, which is hollow in the middle. Four equidistant rotating shafts 2022 are fixedly connected to the hollow part. Connecting rods 203 are rotatably connected to the rotating shafts 2022. One end of the connecting rod 203 along its length has a hole 2031 that rotatably connects to the rotating shaft 2022, allowing the connecting rod 203 to rotate freely on the rotating shaft 2022 to accommodate guardrails of different lengths. A groove 2032 is formed at the other end of the connecting rod 203, within which a telescopic rod 205 is slidably connected. A spring 2051 is fixedly connected to one end of the telescopic rod 205, with one end of the spring 2051 abutting against the bottom of the groove 2032. The telescopic rod 205 extends outwards due to the action of the spring. A cylinder 2052 is fixedly connected to one side of the other end of the telescopic rod 205, and a fixed bracket 206 is slidably connected to the outside of the cylinder 2052.

[0020] Multiple fixing plates 2061 are fixedly connected at equal intervals on both sides of the fixed bracket 206. Fixing bolts 2062 are screwed onto the fixing plates 2061 and connected to the column 102. The fixing plates 2061 and column 102 are fixedly connected by the fixing bolts 2062 through holes drilled in them. The fixed bracket 206 has a long groove 2063 along its length to facilitate the sliding of the cylinder 2052. Multiple limiters 2064 are equally spaced on the outer side of the long groove 2063. The main function of the limiters 2064 is to hold the cylinder 2052 in place, preventing the telescopic rod 205 from moving freely. The internal space of the long groove 2063 is larger than the space at its opening. The diameter of the end of the cylinder 2052 near the telescopic rod 205 is the same distance from the opening of the long groove 2063. This allows the cylinder 2052 to slide freely within the long groove 2063, but it cannot easily detach from it.

[0021] The connecting rod 203 is slidably connected to a slide 204. The slide 204 can slide freely on the connecting rod 203. The main reason is that the connecting rod 203 will rotate according to the length of the column 102. If the fastening table 208 connected to the slide 204 does not move, it may not always abut against the bar on the guardrail 101. It may be located between two bars. Therefore, when the slide 204 moves, the fastening table 208 moves to the position of the bar on the guardrail 101. Then, by rotating the threaded tube 207, the fastening table 208 abuts against the bar on the guardrail 101. A threaded post 2041 is fixedly connected to one end of the carriage 204 near the guardrail 101. A threaded tube 207 is threaded onto the outside of the threaded post 2041. A rod is fixedly connected to the outside of the threaded tube 207. A threaded post 2081 is threaded onto one end of the threaded tube 207. A fastening platform 208 is fixedly connected to one end of the threaded post 2081, and the fastening platform 208 abuts against the guardrail 101. The fastening platform 208 is made of rubber. The reason for using rubber is that it can clamp more tightly when in contact with the guardrail, the soft rubber is less likely to damage the guardrail, and it can increase friction and prevent movement.

[0022] Two interlocking central fixing frames 209 are fixedly connected to the middle pole of the guardrail 101. Each central fixing frame 209 includes a clamping frame 2093 around the middle pole of the guardrail 101. The clamping frame 2093 has a concave structure. At one end of the protruding part of the clamping frame 2093, a protruding rail 2091 is fixedly connected, and at the other end, a groove 2092 is formed. The two clamping frames 2093 are connected in opposite directions and interlock, locking onto the outer perimeter of the middle pole of the guardrail 101. Because the guardrail 101 has not only longitudinally arranged poles fixed to the concrete wall 1, but also laterally connected poles, it is designed as a separate unit. The central fixing frames 209 and the central turntable 202 are fixedly connected by the protruding rails 2091 and the grooves 2092. Then, long bolts 201 are used to fix the central fixing frames 209 and the central turntable 202. In this way, the fixing mechanisms 2 on both sides of the guardrail 101 both abut against the guardrail 101 and are fixedly connected to the posts 102, increasing the overall structural stability. A long column 2094 is fixedly connected to one side of the clamping frame 2093, and a threaded hole 2095 is located at one end of the long column 2094. A threaded hole 2021 is located at the geometric center of the central turntable 202. A long bolt 201 is screwed onto the threaded hole 2021, and the long bolt 201 is screwed into the threaded hole 2095.

[0023] Working process: First, drill holes in the column 102 of the concrete wall 1 according to the position of the fixing bolts 2062 on the fixing bracket 206. Then, fix the fixing bracket 206 in this fixing mechanism 2 close to the opening of the column 102 and fix it to the column 102 with the fixing bolts 2062. When fixing the fixing brackets 206 on both sides to the column 102, first adjust the position of the telescopic rod 205 on the long groove 2063 so that the cylinder 2052 is stuck in the limit 2064 to adapt to the distance between the two columns 102. Then slide the slide 204 so that the fastening platform 208 is located on one side of the guardrail 101. Rotate the threaded tube 207 so that the fastening platform 208 moves closer to the guardrail and abuts against it. Finally, move the two central fixing brackets 209 to both sides of the guardrail 101 and slide them together, so that the convex rails 2091 and grooves 2092 on the two central fixing brackets 209 engage with each other. Then, thread the long bolts 201 into the threaded holes 2021 on the central turntable 202 and 2095 on the long column 2094 respectively to fix them in place. Figure 1 As shown.

[0024] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
