Detailed Implementation

[0037] This utility model provides a delineator bracket and a beam-column guardrail structure. By using the delineator bracket in this application, the connection between the delineator and the guardrail can be achieved without drilling holes in the beam-column guardrail structure.

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0040] Road delineators are traffic safety facilities installed along the edges of roads to display road boundaries, guide vehicles, and have retroreflective properties. Commonly available road delineators are connected to beam-and-column guardrail structures by drilling holes. Drilling holes in the guardrail structure directly damages the base material, especially for guardrails treated with hot-dip galvanizing or other anti-corrosion methods. The damaged anti-corrosion layer at the drilling point loses its protective function, allowing moisture and oxygen to easily penetrate and accelerate the rusting process. Rust not only reduces the strength of the guardrail structure, affecting its protective performance, but also causes the connection between the bracket and the guardrail structure to loosen, leading to unstable installation of the road delineator and posing a safety hazard.

[0041] Furthermore, since the spacing between posts in a beam-and-column structure is generally fixed, delineator brackets on the market cannot flexibly adjust the installation distance when installing delineators on these posts.

[0042] Please refer to Figures 1 to 3 , Figure 1 This is a top view of the annular clamp in an embodiment of this utility model; Figure 2 yes Figure 1 Axonometric view; Figure 3 This is one of the structural schematic diagrams of a beam-column guardrail structure; Figure 3 This is the second structural diagram of a beam-column guardrail structure.

[0043] This application provides a contour marker 5 bracket, which includes an annular clamp 21 and a locking member 3 for locking the annular clamp 21. The annular clamp 21 forms a receiving cavity 21b, which is used to pass through the crossbeam 1 of the beam-column guardrail structure.

[0044] The annular clamp 21 can be circular, elliptical, flat elliptical, polygonal, etc. The annular clamp 21 is provided with an opening 21a-2, which is locked by a locking member 3. The locking member 3 can be a bolt and nut, a quick clamp, a ratchet mechanism, a cam locking mechanism, or a wedge locking mechanism, etc., which can be selected by those skilled in the art as needed.

[0045] By using a ring-shaped clamp 21 type of outline marker 5 bracket to connect the outline marker 5 to the beam 1 of the beam-column guardrail structure, drilling holes in the beam 1 is avoided, which would damage the structure of the beam 1. This ensures the integrity of the beam 1, avoids negative impacts on the strength and service life of the beam-column guardrail structure, and also reduces installation costs and construction difficulty.

[0046] Furthermore, by connecting the outline marker 5 bracket in this application to the crossbeam 1 of the beam-column guardrail structure, the installation distance of the outline marker 5 can be flexibly adjusted.

[0047] In such Figures 1 to 3 In this example, as an illustration, the receiving cavity 21b enclosed by the annular clamp 21 is configured to conform to the cross section of the beam 1. Thus, the annular clamp 21 can fit tightly against the outer wall of the beam 1 of the beam-column guardrail. This close fit reduces the gap between the delineator 5 bracket and the beam 1, preventing the delineator 5 bracket from wobbling and ensuring the installation accuracy and indicating effect of the delineator 5.

[0048] Of course, in addition to conforming to the cross-section of the beam 1, the cross-section of the ring clamp 21 can also be different from that of the beam 1, thereby increasing the compatibility of the ring clamp 21 with different types of beams 1.

[0049] In such Figure 3 In the example shown, the cross-section of the receiving cavity 21b is a flattened ellipse and fits against the beam 1, which has a vertical cross-section of a flattened ellipse. The major axis s1 of the cross-section of the beam 1 coincides with the horizontal direction.

[0050] The annular clamp 21 has two opposing straight wall sections 21c and an arc-shaped wall section 21a connecting the two straight wall sections 21c. After the annular clamp 21 is installed on the crossbeam 1, the two straight wall sections 21c extend along... Figure 3 The two arc-shaped wall segments 21a are vertically distributed and relatively vertically, with the two segments along the direction of the arc. Figure 3 The front and back are relative in the horizontal direction.

[0051] As an alternative example, one arc-shaped wall segment 21a is used to directly or indirectly connect the delineator 5, and the opening 21a-2 is provided in another arc-shaped wall segment 21a. This ensures the reflective angle of the delineator 5.

[0052] To adjust the installation distance between the delineator 5 and the crossbeam 1, the delineator 5 bracket also includes an adapter 4 for connection to the annular clamp 21. The adapter 4 is used to connect the delineator 5. The surface of the adapter 4 that contacts the delineator 5 is 41b. This improves the compatibility between the adapter 4 and the delineator.

[0053] like Figure 3 and Figure 4 As shown, adapter 4 can be adapted to Figure 3 The trapezoidal outline marker 5 in the text can also be adapted to Figure 4 The plate-shaped outline marker 5 in the text can also be adapted to other outline markers 5 with flat connecting surfaces.

[0054] As an alternative example, the adapter 4 includes a support 41 for fixing the outline 5 and a connecting part 42 that is angled to the support 41. The connecting part 42 is bent to form a bending region 42a that is tangent to the outer wall of the annular clamp 21.

[0055] Further reference Figure 1 and Figure 2In the structure shown, the support portion 41 extends along its short side and is spaced apart from the arcuate wall segment 21a along its long side. Connecting portions 42 are provided at both ends of the support portion 41, located between the arcuate wall segment 21a and the support portion 41. The two connecting portions 42 extend towards the center of the support portion 41 at an acute angle to it. The end of the connecting portion 42 furthest from the support portion 41 extends in the opposite direction towards the support portion 41 to form a protruding ridge, which serves as a bending region 42a.

[0056] exist Figure 1 In the middle, the convex ridge extends along the direction perpendicular to the straight surface, in Figure 2 In the middle, the convex ridge is tangent to the arc wall segment 21a along a line.

[0057] The design of bending area 42a being tangent to the outer wall of the clamp allows the stress of the adapter 4 to smoothly transition along the contact surface and deform when under force; in addition, by setting the bent connection part 42, the structural strength of the outline 5 bracket and its ability to resist loads (wind loads, impact loads) are increased.

[0058] In order to drive the adapter 4 in the embodiment of this application to deform and adjust the distance between the outline 5 and the crossbeam 1.

[0059] The outline marker 5 bracket is also equipped with threaded fasteners (not shown in the figure), and the adapter 4 is connected to the annular clamp 21 via the threaded fasteners. This allows adjustment of the connection strength between the adapter 4 and the annular clamp 21 via the threaded fasteners, control of the deformation of the adapter 4, and adjustment of the distance between the outline marker 5 and the crossbeam 1.

[0060] Specifically, the support part 41 has a first hole 41a, and the annular clamp 21 has a second hole 21a-1 that matches the first hole 41a; the second hole 21a-1 is located in the arc wall section 21a, and the first hole 41a and the second hole 21a-1 are used to insert the screw. Locking nuts are provided at both ends of the screw, so that a preload can be applied to the support part 41 through the locking nuts to drive the adapter 4 to deform.

[0061] The deformation of the adapter 4 and the distance between the support part 41 and the outer wall of the annular clamp 21 can be adjusted by inserting a screw into the first hole 41a and the second hole 21a-1 and engaging with the locking nut.

[0062] In the example shown, the first hole 41a is located at the center of the support portion 41. The support portion 41 is a rectangular plate, and the center of the support portion 41 is located at the intersection of the two diagonals of the rectangular support portion 41.

[0063] The screw passes through the first hole 41a at the center of the support part 41 and the second hole 21a-1 set in the annular clamp 21. By adjusting the axial preload through the locking nut, the bending stiffness of the adapter 4 can be continuously adjusted to ensure that the adjustment force is applied symmetrically and to avoid the additional bending moment caused by eccentric load.

[0064] The extensions of the first hole 41a and the second hole 21a-1 pass through the center of the annular clamp 21. The second hole 21a-1 and the opening 21a-2 of the annular clamp 21 are opposite each other along the long axis s1. This ensures coaxiality during installation with the crossbeam 1.

[0065] During the adjustment process, the screw passes through the center hole of the clamp, so that the adjustment force is symmetrically distributed along the structural axis, avoiding the generation of additional bending moment.

[0066] The annular clamp 21 has a center, which is located at the intersection of the major axis s1 and the minor axis s2 of the receiving cavity 21b. The extension lines of the first hole 41a and the second hole 21a-1 pass through the center of the annular clamp 21, so that the force can be evenly distributed on the annular clamp 21 during the tightening of the adapter 4, avoiding stress concentration.

[0067] In the aforementioned embodiments, the outline marker 5 bracket is made of zinc-aluminum-magnesium high-strength steel.

[0068] Zinc-aluminum-magnesium high-strength steel has high strength and high toughness, and can withstand large external forces, such as the impact of vehicle collisions and strong wind loads, to ensure the structural stability of the outline marker 5 bracket in harsh environments and prevent the outline marker 5 from falling off due to deformation or breakage of the outline marker 5 bracket.

[0069] This application also provides a beam-column guardrail structure, including a plurality of horizontal beams 1. The cross-section of the horizontal beams 1 along the vertical direction is a flat ellipse, and the major axis s1 of the cross-section of the horizontal beams 1 coincides with the horizontal direction. This not only ensures a high impact resistance level of the guardrail structure, but also improves the ventilation rate of the guardrail structure.

[0070] The beam-column guardrail structure also includes a contour marker 5 bracket fitted onto the crossbeam 1, which is the aforementioned contour marker 5 bracket.

[0071] This avoids drilling holes in the crossbeam 1 during the installation of the outline marker 5 bracket, which would damage the structure of the crossbeam 1, ensuring the integrity of the crossbeam 1, avoiding negative impacts on the strength and service life of the beam-column guardrail structure, and also reducing installation costs and construction difficulty.

[0072] Furthermore, by connecting the outline marker 5 bracket in this application to the crossbeam 1 of the beam-column guardrail structure, the installation distance of the outline marker 5 can be flexibly adjusted.

[0073] In the aforementioned implementation, the impact resistance level of the beam-column guardrail structure is SA level.

[0074] Avoiding drilling into beam-column guardrail structures ensures their high impact resistance.

[0075] After the outline marker 5 structure and the crossbeam 1 are installed, the central axis of the annular clamp 21 coincides with the central axis of the crossbeam 1. During installation, the coaxiality of the two can be adjusted by setting washers or other methods.

[0076] In such Figure 3 In the example shown, the beam-column guardrail structure also includes a first horizontal beam 1, a second horizontal beam 1, and a third horizontal beam 1 distributed vertically at intervals. The second horizontal beam 1 is located between the first horizontal beam 1 and the third horizontal beam 1. The delineator 5 bracket is set on the second horizontal beam 1. By setting it on the second horizontal beam 1, the reflective angle of the delineator 5 can be reasonably set.

[0077] In practical use, the opening 21a-2 of the annular clamp 21 can be opened and fitted onto the crossbeam 1. Alternatively, the annular clamp 21 can be fitted onto the crossbeam 1 before it is connected to the column. The size of the opening 21a-2 of the annular clamp 21 can be changed using the locking element 3, thereby adjusting the inner diameter of the annular clamp 21. The locking element 3 ensures a tight fit between the annular clamp 21 and the outer wall of the crossbeam 1. At this time, the central axis of the annular clamp 21 coincides with the central axis of the crossbeam 1. If there is a certain deviation between them, shims can be added during installation to adjust their coaxiality.

[0078] The advantages of this application are:

[0079] First, installation without drilling: The outline marker 5 bracket adopts a ring clamp 21 structure, which tightens and fixes the guardrail by adjusting the inner diameter of the ring clamp 21, eliminating the need to drill holes in the guardrail. This avoids damage to the guardrail's anti-corrosion layer and base material caused by drilling, maintains the integrity of the guardrail, and extends its service life. At the same time, the installation process does not require the use of large tools, greatly improving installation efficiency and reducing installation costs.

[0080] Secondly, the ring clamp 21 can fit tightly against the outer wall of the beam 1 of the beam-column guardrail. The tight fit reduces the gap between the outline marker 5 bracket and the beam 1, preventing the outline marker 5 bracket from shaking and ensuring the installation accuracy and indication effect of the outline marker 5.

[0081] Third, zinc-aluminum-magnesium high-strength steel possesses high strength and toughness, enabling it to withstand significant external forces, such as the impact of vehicle collisions and strong wind loads. This ensures the structural stability of the delineator 5 bracket in harsh environments, preventing the delineator 5 from falling off due to deformation or breakage. Its excellent corrosion resistance allows for long-term use in humid, saline, and acid rain-prone environments, reducing maintenance and replacement frequency and lowering maintenance costs. Compared to ordinary carbon steel and aluminum alloys, zinc-aluminum-magnesium high-strength steel has significant advantages in strength and corrosion resistance, better meeting the requirements of outdoor transportation facilities.

[0082] Fourth, the distance between the crossbeam 1 and the outline 5 can be adjusted using threaded fasteners.

[0083] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
