Description

Technical Field

[0001] This utility model relates to the field of bridge guardrail construction technology, specifically to a protective splicing guardrail that can be quickly assembled. Background Technology

[0002] Bridge railings, as crucial facilities for ensuring traffic safety, primarily function to prevent vehicles from crossing boundaries while also meeting the aesthetic requirements of bridges. Currently, the industry commonly uses welding or bolted connections for railing assembly. While this ensures structural strength, it reveals significant drawbacks in actual construction: Firstly, traditional welding requires specialized equipment and skilled workers, resulting in low construction efficiency and difficulty adapting to rapid construction demands. Secondly, although bolted assembly allows for disassembly, each connection point requires individual bolt tightening, leading to complex and time-consuming installation procedures. This is especially problematic in large-scale bridge projects, where thousands of connection points exponentially increase the construction period, severely impacting project progress.

[0003] Therefore, it is necessary to propose a protective interlocking guardrail that can be quickly assembled. Compared with existing technologies, it combines rapid assembly with structural reliability, greatly improving the assembly speed of the guardrail. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and propose a protective splicing guardrail that can be quickly assembled. Compared with the prior art, it has both rapid assembly and structural reliability, which greatly improves the assembly speed of the guardrail.

[0005] The purpose of this utility model is achieved through the following technical solution: a quick-assembly protective splicing guardrail, comprising several pillars and rain-wave beams, wherein at least one first anti-blocking block and at least one second anti-blocking block are provided on the pillars, and two outwardly extending support plates are provided on the side of the first anti-blocking block away from the pillar, and a snap-fit ​​interface is formed between the two support plates and the first anti-blocking block, and a C-shaped plate is provided on the second anti-blocking block, wherein the rain-wave beam and the C-shaped plate are installed on the second anti-blocking block by a first fixing bolt, and the rain-wave beam is detachably connected to the snap-fit ​​interface.

[0006] The two support plates are provided with a first snap-fit ​​protrusion on one side of each other, and the rain-wave beam plate is provided with a second snap-fit ​​protrusion that matches the number and position of the first snap-fit ​​protrusion.

[0007] The support includes 114 uprights, and the upper end of the 114 uprights is provided with 127 outer sleeves.

[0008] The first and second anti-blocking blocks have an arc surface on the side near the support column that matches the support column.

[0009] Both the first and second anti-blocking blocks are detachably connected to the support column.

[0010] Both the first and second anti-blocking blocks are connected to the support column by the second fixing bolt.

[0011] An anti-theft clamping nut A is provided on one end of the second fixing bolt, and a washer is provided between the anti-theft clamping nut A and the outer wall of the support column. An anti-theft clamping nut B is provided on the other end of the anti-theft clamping nut A.

[0012] The support column is provided with square connecting columns that match the position and number of the first and second anti-blocking blocks. The square connecting column is rotatably provided with a square head that matches its shape and size at the end away from the support column. The square head is provided with protruding blocks on its periphery. The first and second anti-blocking blocks are provided with square openings that match the shape, size and position of the square connecting columns on the side closer to the support column.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0018] A type of quick-assembly protective interlocking guardrail, reference Figures 1-5 It includes several support columns 1 and a rain-wave beam slab 2. The support column 1 includes a 140 column 21. A 152 sleeve 22 is provided at the upper end of the 140 column 21. A 127 outer sleeve 12 is provided at the upper end of the 152 sleeve 22. A first anti-blocking block 3 and a second anti-blocking block 4 are provided on the support column 1.

[0019] The first anti-blocking block 3 has outwardly extending support plates 5 at both its upper and lower front ends. The two support plates 5 and the front of the first anti-blocking block 3 form a snap-fit ​​interface 6 that can be detachably snapped into the rain-wave beam plate 2. A first snap-fit ​​protrusion 9 is provided on each adjacent side of the two support plates 5. The lower half of the rain-wave beam plate 2 has second snap-fit ​​protrusions 10 that correspond in shape, number, and position to the first snap-fit ​​protrusions 9. The upper half of the rain-wave beam plate 2 and the C-shaped plate 7 are connected to the second anti-blocking block 4 via a first fixing bolt 8.

[0020] The first anti-blocking block 3 and the second anti-blocking block 4 have an arc surface 13 on the side near the support column 1 that matches the support column 1. The first anti-blocking block 3 and the second anti-blocking block 4 are connected to the support column 1 by a second fixing bolt 14. The second fixing bolt 14 is threaded through the support column 1. One end of the second fixing bolt 14 is fitted with an anti-theft clamping nut A 15, a washer 16, and an anti-theft clamping nut B 17. The washer 16 is located between the anti-theft clamping nut A 15 and the outer wall of the support column 1. The anti-theft clamping nut A 15 has a clamping groove on the side away from the outer wall of the support column 1, and the anti-theft clamping nut B 17 is installed in the clamping groove.

[0021] After the operator installs the first anti-blocking block 3 and the second anti-blocking block 4 on the support column 1, the rain-wave beam plate 2 can be snapped into the locking interface 6 to pre-position the rain-wave beam plate 2. Finally, the C-shaped plate 7, the second anti-blocking block 4, and the rain-wave beam plate 2 are fixedly connected by the first fixing bolt 8. For those skilled in the art, the C-shaped plate 7 can also be snapped into the rain-wave beam plate 2. For those skilled in the art, it is not necessary for the first anti-blocking block 3 to be below and the second anti-blocking block 4 to be above on the support column 1; in some cases, the first anti-blocking block 3 can be above and the second anti-blocking block 4 below.

[0022] As a further improvement to this utility model, based on the above-mentioned cases, further extensions can be made to provide a variety of novel embodiments.

[0023] As a second embodiment of this utility model, based on embodiment 1, and referring to... Figure 6 The support column 1 may include 114 uprights 11. The upper end of the 114 uprights 11 is provided with an outer sleeve 12 12.

[0024] As a third embodiment of this utility model, based on embodiment 1 or 2, and referring to... Figure 7 The support column 1 is provided with square connecting columns 18, each corresponding to the position and number of the first anti-blocking block 3 and the second anti-blocking block 4. Each square connecting column 18 has a rotatable square head 19 of the same size and shape. Four protruding blocks 20 are evenly distributed around the square head 19. The first anti-blocking block 3 and the second anti-blocking block 4 have square openings on the side near the support column 1, corresponding to the size, shape, and position of the square connecting columns 18. Each square opening has a passageway around its perimeter, corresponding to the position, shape, and size of the protruding blocks 20.

[0025] When the first anti-blocking block 3 and the second anti-blocking block 4 need to be installed, rotate the square head 19 so that the protrusion 20 matches the position of the through hole. At this time, insert the anti-blocking block 4 into the square connecting post 18, and then rotate the square head 19 so that the protrusion 20 no longer matches the position of the through hole. At this time, the anti-blocking block cannot leave the square connecting post 18.

[0026] For those skilled in the art, the square head 19 and the square connecting post 18 can be modified to a threaded connection similar to that between a bottle cap and a bottle neck. When the square head 19 is tightened on the square connecting post 18, the protrusion 20 does not match the position of the opening. Alternatively, an anti-misoperation structure can be introduced into the connection structure between the square head 19 and the square connecting post 18, requiring a certain force to rotate the square head 19. Since the anti-misoperation structure is a very common structure in the art, it will not be described in detail here.
