Description

Technical Field

[0001] The utility model relates to the field of stainless steel guardrail auxiliary components, in particular to a bridge deck stainless steel guardrail. Background Art

[0002] The bridge deck stainless steel guardrail is also called the bridge anti-collision guardrail, which refers to the guardrail installed on the side of the bridge. Its purpose is to prevent out-of-control vehicles from going over the bridge. At the same time, it has the function of preventing vehicles and pedestrians from breaking through, passing under, and climbing over the bridge, as well as beautifying the bridge structure.

[0003] According to different structural characteristics, bridge guardrails are mainly divided into three types: beam-column guardrails, reinforced concrete wall guardrails and combined guardrails. Among them, beam-column guardrails are the most commonly used, which are usually composed of beams and columns. At the same time, beam-column guardrails are divided into metal guardrails and concrete guardrails. Metal beam-column guardrails have been widely used due to their simple structure, easy construction, good protection effect and other characteristics. Therefore, bridge deck stainless steel guardrails are currently the most commonly used metal beam-column guardrails.

[0004] When designing a metal beam-column guardrail, it is usually composed of a number of beams and a row of columns for supporting and fixing the beams. The row of columns includes multiple columns that are arranged along the length of the guardrail and are all arranged upright. Since stainless steel products have high strength and hardness as well as good plasticity and toughness, most of the existing metal beam-column guardrails use stainless steel guardrails, and the columns used in stainless steel guardrails are also stainless steel columns.

[0005] However, when the current bridge deck stainless steel guardrails are specifically assembled and arranged, the stainless steel guardrail part and the stainless steel column part are usually fixedly connected by welding technology, which is difficult to construct on site and not easy to assemble quickly. At the same time, once the stainless steel guardrail part and the stainless steel column part are welded, the connection surface between the stainless steel guardrail part and the stainless steel column part cannot be replaced, resulting in poor flexibility in use. In addition, during subsequent use, when the stainless steel guardrail part is deformed and damaged due to accidental collision, it is often necessary to cut and re-weld it, which is very inconvenient to remove and replace.

[0020] The above-mentioned bridge deck stainless steel guardrail is adopted. Specifically, in the process of combining the guardrail beam body and the guardrail column body into a stainless steel guardrail, the guardrail beam body can be quickly limited and combined between the guardrail column bodies at both sides by means of the vertical sliding cooperation between the positioning block and the positioning groove. The combined arrangement method of the guardrail beam body and the guardrail column body is simple and easy to operate, which replaces the welding combination connection method of the guardrail beam body and the guardrail column body, and is convenient for quickly combining the guardrail beam body and the guardrail column body at the bridge deck construction site. Then, when multiple guardrail beam bodies are horizontally arranged by means of the vertical sliding cooperation between the positioning blocks at both ends and the positioning grooves at both sides. After being between the guardrail post bodies at the two side positions, the pressing block is installed on the top of the positioning groove by means of vertical sliding cooperation between the pressing block and the top of the positioning groove, and then the pressing block can be detachably fixed to the top of the positioning groove by holding the pull ring so that the locking rod can coaxially cooperate with the locking hole through the corresponding matching hole. The combined fixing method of the pressing block and the positioning groove is simple and easy to operate, and then the pressing block is used to block the top of the positioning groove to limit the multiple positioning blocks in the positioning groove from sliding out vertically, so that the guardrail crossbeam body can be detachably fixed between the guardrail post bodies at the two side positions to complete the installation, and then the guardrail post bodies can be detachably fixed to the top of the guardrail post bodies at the two side positions. The guardrail is fixed by driving bolts into the corresponding installation positions on the bridge surface through the anchor bolt holes of the base, and finally the plugs are installed on the top of the guardrail column bodies in turn for sealing. When the guardrail beam body needs to be removed between the guardrail column bodies at both sides later, the plugs are first removed from the top of the guardrail column body, and then the pull ring is simply held again to make the locking rods successively disengage from the locking holes and the matching holes, so that the pressure block can be slid out from the top of the positioning groove. The separation method of the pressure block and the positioning groove is simple and easy to operate. After the pressure block is removed from the top of the positioning groove, since the top of the positioning groove is open, the guardrail beam can be lifted up The method of the main body enables the positioning blocks to slide out from the top along the positioning grooves, so that the guardrail beam body can be detached from the guardrail post bodies at both sides by sliding the positioning blocks out from the top along the positioning grooves, which facilitates the subsequent replacement of the damaged guardrail beam body without the need for replacement operations by cutting and re-welding. It should be noted that when the multiple guardrail post bodies are disassembled, they should be disassembled in sequence from top to bottom, and when the multiple guardrail post bodies are combined, the multiple positioning blocks should be allowed to slide down from the top of the positioning grooves in sequence. Specifically, in the combination of the substrate on the outer surface of the guardrail post body, before the pressing block of the limit locking assembly is installed,The base plate can be detachably fixed to the outer surface of the guardrail post body by the way that the connecting piece passes through the mounting hole and is coaxially threadedly engaged with the connecting hole, and the base plate and the outer surface of the guardrail post body can be separated from each other by only making the connecting piece successively disengage from the connecting hole and the mounting hole. The combination and separation method of the base plate and the outer surface of the guardrail post body is simple and easy to operate, which is convenient for quickly combining the base plate on the outer surface of the guardrail post body for use, and is also convenient for quickly removing the base plate for replacement and maintenance at a later time, and replacing the corresponding outer surface of the base plate when it is installed around the guardrail post body. Specifically, when replacing the corresponding outer surface of the base plate when it is installed around the guardrail post body, since the outer surfaces around the guardrail post body are all provided with the connecting holes corresponding to the positions of the mounting holes of the base plate, the base plate can be installed on any outer surface around the guardrail post body by the way that the connecting piece passes through the mounting hole and is coaxially threadedly engaged with the connecting hole, thereby improving the convenience of the base plate in the guardrail The flexibility of the outer surface of the guardrail post body when used in combination makes it easy to realize the same-direction extension layout between the adjacent guardrail beam bodies on both sides by installing the substrate on the two non-adjacent outer surfaces of the guardrail post body, and at the same time, it is easy to realize the vertical extension layout between the adjacent guardrail beam bodies on both sides by installing the substrate on the two adjacent outer surfaces of the guardrail post body, enriching the layout application scenarios, and when the corresponding outer surface of the substrate is replaced when installed around the guardrail post body, since the outer surfaces around the guardrail post body are all provided with the locking holes corresponding to the matching holes at the top of the positioning groove, it is ensured that when the substrate is installed and combined on different outer surfaces of the guardrail post body, the locking rod can pass through the matching holes and coaxially cooperate with the locking holes on the corresponding outer surfaces, thereby ensuring that when the substrate is installed and combined on any outer surface around the guardrail post body, the pressing block can be detachably fixed and blocked at the top of the positioning groove to achieve the limit locking of the positioning block.

[0021] The beneficial effects are as follows: 1. The utility model can quickly limit and combine the guardrail beam body between the guardrail column bodies at both sides by means of the vertical sliding cooperation between the positioning block and the positioning groove. The combination layout of the guardrail beam body and the guardrail column body is simple and easy to operate, replacing the welding combination connection method of the guardrail beam body and the guardrail column body, which is convenient for quickly combining the guardrail beam body and the guardrail column body at the bridge deck construction site;

[0022] 2. After the guardrail beam body and the guardrail column body are combined together, the pressing block can be detachably fixed to the top of the positioning groove by means of vertical sliding cooperation between the pressing block and the top of the positioning groove and coaxial cooperation between the locking rod and the locking hole through the matching hole. The combined fixing method of the pressing block and the positioning groove is simple and easy to operate. Then, the pressing block blocks the top of the positioning groove to prevent multiple positioning blocks in the positioning groove from sliding out vertically, so that the guardrail beam body can be detachably fixed between the guardrail column bodies at both sides to complete the installation;

[0023] 3. The pressing block can be slid out of the top of the positioning groove only after the locking rod is disengaged from the locking hole and the matching hole. The separation method of the pressing block and the positioning groove is simple and easy to operate. After the pressing block is removed from the top of the positioning groove, the positioning blocks can slide out from the top along the positioning groove. Thus, the guardrail beam body can be detached from the guardrail column bodies at both sides by sliding the positioning blocks out from the top along the positioning groove, which is convenient for the later replacement of the damaged guardrail beam body separately without the need for replacement by cutting and re-welding.

[0024] 4. The base plate can be detachably fixed to the outer surface of the guardrail post body by the way that the connecting piece passes through the installation hole and is threaded with the connecting hole coaxially. The base plate and the outer surface of the guardrail post body can be separated from each other by only making the connecting piece disengage from the connecting hole and the installation hole in turn. The combination and separation method of the base plate and the outer surface of the guardrail post body is simple and easy to operate, which is convenient for quickly combining the base plate on the outer surface of the guardrail post body for use, and at the same time, it is convenient to quickly remove the base plate for replacement and maintenance at a later time and replace the corresponding outer surface of the base plate when it is installed around the guardrail post body;

[0025] 5. The outer surfaces around the guardrail column body are all provided with connection holes corresponding to the mounting holes of the substrate, and then the substrate can be installed on any outer surface around the guardrail column body by passing the connecting piece through the mounting hole and coaxially threaded with the connecting hole, which improves the flexibility of the substrate when used in combination with the outer surface of the guardrail column body, so that it is convenient to realize the same-direction extension layout between the adjacent guardrail beam bodies on both sides by installing the substrate on the two non-adjacent outer surfaces of the guardrail column body, and at the same time, it is convenient to realize the vertical extension layout between the adjacent guardrail beam bodies on both sides by installing the substrate on the two adjacent outer surfaces of the guardrail column body, which enriches the layout application scenarios;

[0026] 6. The outer surfaces around the guardrail column body are all provided with locking holes that correspond to the matching holes on the top of the positioning groove, thereby ensuring that when the base plate is installed and combined on different outer surfaces of the guardrail column body, the locking rod can pass through the matching hole and coaxially cooperate with the locking hole on the corresponding outer surface, thereby ensuring that when the base plate is installed on any outer surface combination around the guardrail column body, the pressure block can be detachably fixed and sealed on the top of the positioning groove to achieve limit locking of the positioning block.

[0042] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0043] See also Figure 1-Figure 12As shown, the utility model provides a bridge deck stainless steel guardrail, including a guardrail column body 2 and a guardrail beam body 3. The number of the guardrail column bodies 2 is multiple and all are vertically arranged, and multiple guardrail beam bodies 3 are horizontally arranged between adjacent guardrail column bodies 2 on both sides. Both ends of the guardrail beam body 3 are installed with combined connecting components 6, and the combined connecting components 6 can be detachably fixed on the outer surface of the guardrail post body 2, and the guardrail beam body 3 can be detachably combined with the adjacent guardrail post body 2 through the corresponding combined connecting components 6. Specifically, the combined connecting components 6 include a fixing sleeve 603 and a base plate 602, and both ends of the guardrail beam body 3 are coaxially fixed with a fixing sleeve 603, and the outer ends of the fixing sleeves 603 at both sides are vertically fixed with positioning blocks 605 away from each other. Preferably, the guardrail beam body 3 is a circular cross bar, and the guardrail beam body 3 and the corresponding fixing sleeve 603 are coaxially connected by threaded fit or transition fit, and the fixing sleeve 603 is welded to the outer end face of the corresponding positioning block 605, and the guardrail post body 2 is close to the guardrail post body 2. The outer surface near the outer end of the guardrail beam body 3 is detachably connected to the base plate 602 through the disassembly and assembly component 601, and the outer end surface of the base plate 602 near the end of the guardrail beam body 3 is vertically provided with a positioning groove 604, and the limit locking component 5 can be detachably installed at the top position of the corresponding positioning groove 604, and the positioning blocks 605 corresponding to the ends of the guardrail beam body 3 are vertically slidably matched with the adjacent positioning grooves 604. The purpose of this arrangement is to enable the guardrail beam body 3 to be quickly limited and combined between the guardrail column bodies 2 at the two side positions by vertically sliding with the positioning blocks 605 and the positioning grooves 604. At the same time, the guardrail beam body 3 can be disassembled from the guardrail column bodies 2 at the corresponding two side positions in turn by only sliding the positioning blocks 605 out of the top of the positioning grooves 604 in turn.

[0044] See also Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the disassembly assembly component 601 in the combined connected component 6 is specifically that the four corners of the outer surface of the guardrail column body 2 are vertically opened with connection holes 6012, the four corners of the base plate 602 are vertically opened with mounting holes 6013, and when the base plate 602 is attached to any outer surface of the guardrail column body 2, the mounting holes 6013 are coaxially matched with the connecting holes 6012 of the corresponding surface, and the mounting holes 6013 are coaxially matched with the connecting parts 6011, and the connecting parts 6011 are coaxially matched with the connecting holes 6012 of the corresponding outer surface in a detachable connection manner. The advantage is that the base plate 602 can be detachably fixed to the outer surface of the guardrail column body 2 by means of the connecting piece 6011 passing through the mounting hole 6013 and coaxially threadedly cooperating with the connecting hole 6012. The base plate 602 and the outer surface of the guardrail column body 2 can be separated from each other by only making the connecting piece 6011 successively disengage from the connecting hole 6012 and the mounting hole 6013, which makes it easy to quickly combine the base plate 602 with the outer surface of the guardrail column body 2 for use, and also makes it easy to quickly remove the base plate 602 for replacement and maintenance at a later time and replace the corresponding outer surface of the base plate 602 when it is installed around the guardrail column body 2.

[0045] See also Figure 1-Figure 6As shown, the top of the combined connected components 6 can be detachably connected to a limit locking component 5 for preventing the guardrail beam body 3 from being separated from the guardrail column bodies 2 adjacent on both sides. Specifically, the limit locking component 5 includes a locking hole 506 and a pressing block 502. The top middle position of the outer surface of the guardrail column body 2 is vertically opened with a locking hole 506, and the top inner wall of the positioning groove 604 is vertically opened with a matching hole 504. When the base plate 602 is attached to any outer surface around the guardrail column body 2, the matching hole 504 is aligned with the locking hole 506 on the corresponding surface. 06 coaxial comparison, the top of the positioning groove 604 is vertically slidably matched with a pressure block 502, and the pressure block 502 is vertically inserted with a locking rod 505 in a sliding matching manner, and the inner end of the locking rod 505 coaxially passes through the matching hole 504 and the locking hole 506 at the corresponding position in a detachable connection manner, and the outer end of the locking rod 505 is coaxially fixed with a connecting sleeve 507 for easy holding. The connecting sleeve 507 of the pull ring 501 is preferably welded or fused to the locking rod 505, so that the pull ring 501 can be stably and securely connected through the connecting sleeve 507 506, and the locking rod 505 is coaxially matched with the locking hole 506 through the matching hole 504, so that the pressing block 502 can be detachably fixed to the top of the positioning groove 604, and then the pressing block 502 blocks the top of the positioning groove 604 to limit the multiple positioning blocks 605 in the positioning groove 604 from sliding out vertically, thereby locking the guardrail beam body 3 and the guardrail column body 2 together. The body 3 can be detachably fixed between the guardrail column bodies 2 at both sides to complete the installation. When the pressure block 502 needs to be removed, the locking rod 505 only needs to be disengaged from the locking hole 506 and the matching hole 504 so that the pressure block 502 can slide out from the top of the positioning groove 604, and then the pressure block 502 can be removed from the top of the positioning groove 604 so that the positioning block 605 can slide out from the top along the positioning groove 604, so that the guardrail beam body 3 can be detached from between the guardrail column bodies 2 at both sides by sliding the positioning block 605 out from the top along the positioning groove 604.

[0046] See also Figure 1-Figure 4As shown, the guardrail column body 2 is optimized as follows: the guardrail column body 2 is a rectangular hollow column, and the horizontal cross-sectional shape of the guardrail column body 2 is a regular quadrilateral. This arrangement facilitates the shape and area specifications of the outer surfaces of the guardrail column body 2 to remain consistent, and then facilitates the regular opening of corresponding connection holes 6012 on the outer surfaces on the four sides, and at the same time facilitates the regular opening of corresponding locking holes 506 on the outer surfaces on the four sides, thereby ensuring that the substrate 602 can be successfully installed and fixed on any outer surface around the guardrail column body 2. The top of the guardrail post body 2 is coaxially fixed with a plug 1 for blocking the top, and the bottom end of the plug 1 is vertically extended and fixed with a tightening flange 101, and the outer periphery of the tightening flange 101 is tightly matched with the inner wall of the top of the guardrail post body 2. Preferably, the plug 1 and the tightening flange 101 are both plastic parts and the top extending out of the top of the guardrail post body 2 can be designed with different shapes. The purpose of this arrangement is that, firstly, the plug 1 can block and protect the top of the guardrail post body 2, and at the same time, the plug 1 can also have a certain aesthetic effect. Moreover, since the tightening flange 101 is a plastic part, and then the outer periphery of the tightening flange 101 is connected to the inner wall of the top of the guardrail post body 2 by a tightening fit, it is convenient to apply force later to separate the tightening flange 101 from the guardrail post body 2 and smoothly remove the plug 1.

[0047] At the same time, the bottom end of the guardrail column body 2 is horizontally extended and fixed with a base 4 for fixing it on the bridge deck. Preferably, the coverage area of ​​the base 4 extends beyond the four sides of the guardrail column body 2, and a plurality of anchor bolt holes 401 are vertically opened around the base 4. With such an arrangement, firstly, the contact area between the bottom end of the guardrail column body 2 and the bottom surface can be increased through the base 4. At the same time, after the guardrail column body 2 is placed at the corresponding layout position on the bridge deck, the guardrail column body 2 can be stably placed and fixed to the bridge deck by installing anchor bolts through the anchor bolt holes 401 of the base 4.

[0048] See also Figure 7-Figure 8 As shown, the disassembly assembly 601 of the combined connected assembly 6 is optimized as follows: the connecting parts 6011 are all bolt parts, and the connecting parts 6011 pass through the corresponding mounting holes 6013 and connecting holes 6012 in a threaded engagement manner. This arrangement makes it easy for the connecting parts 6011 to be smoothly tightened or loosened by twisting with a tool, thereby achieving rapid combination and disassembly of the connecting parts 6011 and the mounting holes 6013 and the connecting holes 6012.

[0049] See also Figure 3-Figure 6As shown, the limit locking assembly 5 is optimized as follows: the locking rod 505 is a screw rod, the matching hole 504 and the locking hole 506 are threaded through holes, and the locking rod 505 and the matching hole 504 and the locking hole 506 are coaxially detachably connected by threaded matching. This arrangement makes it easy to quickly combine and disassemble the locking rod 505, the matching hole 504 and the locking hole 506 by holding the pull ring 501 and applying force to twist it.

[0050] The locking rod 505 can also be selected to be a hard rubber rod, the matching hole 504 and the locking hole 506 are all smooth through holes, and the locking rod 505 and the matching hole 504 and the locking hole 506 are all coaxially detachably connected by a tension fit. Such an arrangement makes it easy to quickly combine and disassemble the locking rod 505, the matching hole 504 and the locking hole 506 by holding the pull ring 501 and applying force to press or pull.

[0051] See also Figure 1-Figure 8As shown, the combined connected component 6 and the limit locking component 5 are further optimized as follows: the top of the pressing block 502 is not lower than the top of the positioning groove 604 and the top is horizontally extended outward and fixed with a wing plate 503. The purpose of such a setting is to facilitate the holding of the pressing block 502 to slide into and out of the positioning groove 604 by setting the wing plate 503, and at the same time, the sliding direction of the pressing block 502 can be designed to prevent foolishness and limit the sliding direction of the pressing block 502 to ensure that the sliding direction of the pressing block 502 is correct. Specifically, with respect to the positioning groove 604, the top of the positioning groove 604 is open, and the horizontal cross-sectional shape of the positioning groove 604 is a T-shaped or dovetail-shaped one. Such a setting first facilitates the positioning block 605 and the pressing block 502 to have a good positioning guide design when sliding vertically along the positioning groove 604, and at the same time facilitates ensuring that the positioning block 605 and the pressing block 502 can only slide vertically along the positioning groove 604 and cannot slide out from other directions. Moreover, the positioning grooves 604 are all blind grooves in the vertical direction and are opened from top to bottom. The multiple positioning blocks 605 corresponding to the same positioning groove 604 are stacked and contacted with each other up and down. The top of the positioning block 605 at the highest position is in contact with the bottom of the corresponding pressing block 502, and the bottom of the positioning block 605 at the lowest position is in contact with the bottom of the corresponding positioning groove 604. This arrangement makes it easy for the multiple positioning blocks 605 to slide into place in the positioning groove 604, and can provide obvious prompts by stacking and contacting with each other up and down. At the same time, when the pressing block 502 slides vertically along the positioning groove 604, when the locking rod 5 of the pressing block 502 05 When the pressure block 502 slides down to be coaxial with the matching hole 504 and the locking hole 506, an obvious prompt can be given by the top of the positioning block 605 at the highest position being in contact with the bottom of the corresponding pressure block 502 and the bottom of the positioning block 605 at the lowest position being in contact with the bottom of the corresponding positioning groove 604. In addition, since multiple positioning blocks 605 are stacked and in contact with each other, and the top pressure block 502 is pressed on the top of the positioning block 605 at the top, this also avoids the situation where multiple positioning blocks 605 will slip and change their positions in the positioning groove 604 after the pressure block 502 is fixed.

[0052] By adopting the above structure, specifically in the process of combining the guardrail beam body 3 and the guardrail column body 2 into a stainless steel guardrail, the guardrail beam body 3 can be quickly limited and combined between the guardrail column bodies 2 at both sides by means of the vertical sliding cooperation between the positioning block 605 and the positioning groove 604. The combined arrangement method of the guardrail beam body 3 and the guardrail column body 2 is simple and easy to operate, replacing the welding combination connection method of the guardrail beam body 3 and the guardrail column body 2, which is convenient for quickly combining the guardrail beam body 3 and the guardrail column body 2 at the bridge deck construction site. Then, multiple guardrail beam bodies 3 are horizontally placed between the guardrail column bodies 2 at both sides by means of the vertical sliding cooperation between the positioning blocks 605 at both ends and the positioning grooves 604 at both sides. Finally, the pressing block 502 is installed on the top of the positioning groove 604 by means of vertical sliding cooperation between the pressing block 502 and the top of the positioning groove 604, and then the pressing block 502 can be detachably fixed to the top of the positioning groove 604 by holding the pull ring 501 to make the locking rod 505 pass through the corresponding matching hole 504 and coaxially cooperate with the locking hole 506. The combined fixing method of the pressing block 502 and the positioning groove 604 is simple and easy to operate, and then the pressing block 502 blocks the top of the positioning groove 604 to limit the multiple positioning blocks 605 in the positioning groove 604 from sliding out vertically, so that the guardrail beam body 3 can be detachably fixed between the guardrail column bodies 2 at the two sides to complete the installation, and then the guardrail column bodies 2 can be removed by passing through The anchor bolt holes 401 of the base 4 are fixed by driving bolts into the corresponding installation positions on the bridge surface, and finally the plugs 1 are installed on the tops of the guardrail column bodies 2 in turn for sealing. When the guardrail beam body 3 needs to be removed between the guardrail column bodies 2 on both sides later, the plugs 1 are first removed from the tops of the guardrail column bodies 2, and then the pull ring 501 is simply held again to make the locking rods 505 successively disengage from the locking holes 506 and the matching holes 504, so that the pressing block 502 can be slid out from the top of the positioning groove 604. The separation method of the pressing block 502 and the positioning groove 604 is simple and easy to operate. After the pressing block 502 is removed from the top of the positioning groove 604, since the top of the positioning groove 604 is open, the guardrail beam body can be lifted up 3, the positioning blocks 605 can all slide out from the top along the positioning grooves 604, so that the guardrail beam body 3 can be detached from the guardrail column bodies 2 at both sides by sliding the positioning blocks 605 out from the top along the positioning grooves 604, which is convenient for replacing the damaged guardrail beam body 3 separately in the later stage, without the need to replace it by cutting and re-welding. It should be noted that when multiple guardrail column bodies 2 are disassembled, they should be disassembled in sequence from top to bottom, and when multiple guardrail column bodies 2 are combined, multiple positioning blocks 605 should be allowed to slide downward from the top of the positioning grooves 604 in sequence. Specifically, in the combination of the base plate 602 on the outer surface of the guardrail column body 2, before the pressing block 502 of the upper limit locking assembly 5 is installed,The base plate 602 can be detachably fixed to the outer surface of the guardrail post body 2 by the connection piece 6011 passing through the installation hole 6013 and coaxially threadedly cooperating with the connection hole 6012, and the base plate 602 and the outer surface of the guardrail post body 2 can be separated from each other by only making the connection piece 6011 successively disengage from the connection hole 6012 and the installation hole 6013. The combination and separation method of the base plate 602 and the outer surface of the guardrail post body 2 is simple and easy to operate, which is convenient for quickly combining the base plate 602 on the outer surface of the guardrail post body 2 for use, and is also convenient for later removal. The base plate 602 can be quickly disassembled and replaced for maintenance and replacement of the corresponding outer surface of the base plate 602 when it is installed around the guardrail column body 2. Specifically, when replacing the corresponding outer surface of the base plate 602 when it is installed around the guardrail column body 2, since the outer surfaces around the guardrail column body 2 are all provided with connecting holes 6012 corresponding to the hole positions of the mounting holes 6013 of the base plate 602, the base plate 602 can then be installed on any outer surface around the guardrail column body 2 by passing the connecting piece 6011 through the mounting hole 6013 and then coaxially threadedly cooperating with the connecting hole 6012, thereby improving The flexibility of the substrate 602 when used in combination with the outer surface of the guardrail post body 2 is improved, so that it is convenient to install the substrate 602 on two non-adjacent outer surfaces of the guardrail post body 2 to realize the same-direction extension layout between the adjacent guardrail beam bodies 3 on both sides, and it is also convenient to install the substrate 602 on two adjacent outer surfaces of the guardrail post body 2 to realize the vertical extension layout between the adjacent guardrail beam bodies 3 on both sides, which enriches the layout application scenarios, and when the substrate 602 is replaced and installed around the corresponding outer surface of the guardrail post body 2, due to the guardrail The outer surfaces around the column body 2 are all provided with locking holes 506 that correspond to the matching holes 504 at the top of the positioning groove 604, thereby ensuring that when the base plate 602 is installed and assembled on different outer surfaces of the guardrail column body 2, the locking rod 505 can pass through the matching holes 504 and coaxially cooperate with the locking holes 506 on the corresponding outer surface, thereby ensuring that when the base plate 602 is assembled and assembled on any outer surface around the guardrail column body 2, the pressing block 502 can be detachably fixed and blocked on the top of the positioning groove 604 to achieve the limit locking of the positioning block 605.
