Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a roadbed baffle. Background Technology

[0002] In the construction of concrete pavements, retaining walls are an indispensable tool. They effectively restrict the flow of concrete, thereby ensuring that the smoothness and shape of the pavement meet design requirements. Traditional retaining walls are generally made of channel steel or wooden planks; however, in practical applications, these traditional retaining walls have many problems.

[0003] On the one hand, the connection methods are cumbersome; traditional barriers are usually connected by bolts or welding, which requires a lot of time and effort during assembly and disassembly. This not only increases the labor intensity of construction workers but also seriously affects construction efficiency, leading to project delays. On the other hand, the support stability is insufficient; ordinary barriers lack reliable support leg structures, and during concrete pouring, the concrete will exert lateral pressure on the barriers. Due to the lack of effective support, the barriers are prone to displacement or deformation under lateral pressure, which will affect the construction quality of the road surface and may even lead to unevenness or non-compliant shapes, posing potential risks to subsequent project acceptance and use. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a roadbed baffle, comprising a baffle body having a vertical flat surface, a support leg structure and a pin structure disposed on the back of the flat surface of the baffle body; multiple support leg structures are evenly arranged along the extension direction of the baffle body; the support leg structures fix the baffle body to the ground and maintain the vertical state of the flat surface; the pin structure includes a male head structure fixed to one end of the baffle body and a female head structure fixed to the other end of the baffle body and cooperating with the male head structure; when two baffle bodies are joined end to end, the male head structure at the joining end can be inserted into the corresponding female head structure to fix the two adjacent baffle bodies together.

[0006] By adopting the above structure, the support legs effectively fix the baffle body to the ground, preventing it from shifting during construction and thus improving the structural stability. The pin mechanism allows for rapid assembly by inserting the male end of one baffle body into the female end of an adjacent baffle body, significantly reducing assembly and disassembly time, improving construction efficiency, and reducing the workload of construction workers.

[0007] Preferably, the baffle body is a channel steel structure with a flat convex surface. One side of the channel steel is placed flush with the ground, and the support leg structure and the pin structure are both fixed in the groove of the channel steel. This structural design gives the channel steel structure high strength and stability, enabling it to withstand significant lateral pressure from concrete. Furthermore, placing the support leg structure and the pin structure in the groove not only saves space but also protects the structure and extends its service life.

[0008] Preferably, the baffle body has reinforcing ribs spaced at intervals on the back of its flat surface, with the ribs arranged vertically. This structural design further enhances the structural strength of the baffle body, improves its resistance to deformation, and ensures that the baffle maintains a stable shape during construction.

[0011] Preferably, the support leg includes interconnected horizontal and diagonal support legs, and anchor holes located at the intersection of the horizontal and diagonal support legs. The other end of the horizontal support leg is fixed to the bottom of the rotating shaft, with its axis perpendicular to the central axis of the rotating shaft. The other end of the diagonal support leg is fixed to the top of the rotating shaft, forming a right-angled triangle structure with the rotating shaft and the horizontal and diagonal support legs. This right-angled triangle structure provides high stability and effectively secures the baffle body to the ground. The anchor holes facilitate further securing of the support leg using ground anchors or similar methods, improving the reliability of the support. By inserting anchor rods into the anchor holes, the support leg is fixed to the ground, preventing movement.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] The orientations mentioned in this specification are based on the orientation of the roadbed baffle of this utility model when it is working normally, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0020] like Figure 1 and Figure 2 As shown, a roadbed baffle includes a baffle body 1 having a vertical flat surface 11, a support leg structure 2 and a pin structure 3 disposed on the back of the flat surface 11 on the baffle body 1.

[0021] The baffle body 1 is a channel steel structure, with a flat surface 11 on the convex side of the channel steel, which contacts the concrete. One side of the channel steel is placed close to the ground to increase the contact area and ensure the stability of the baffle body 1. The support leg structure 2 and the pin structure 3 are both fixed in the grooves of the channel steel. The channel steel structure has high strength and stability, and can withstand large lateral pressure from the concrete; at the same time, placing the support leg structure 2 and the pin structure 3 in the grooves not only saves space but also protects the structure and extends its service life.

[0022] The baffle body 1 has reinforcing ribs 12 spaced at intervals on the back of the flat surface 11. The reinforcing ribs 12 are vertically arranged. The reinforcing ribs 12 further enhance the structural strength of the baffle body 1, improve its resistance to deformation, and ensure that the baffle can maintain a stable shape during construction.

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, multiple support leg structures 2 are evenly arranged along the extension direction of the baffle body 1; in this embodiment, three are provided; their function is to fix the baffle body 1 on the ground and keep the flat surface 11 vertical; thereby providing stable support for the baffle and preventing displacement or deformation under the action of concrete lateral pressure.

[0024] The support leg structure 2 can be a fixed structure, which is welded to the baffle body 1. In this embodiment, for easy storage, the support leg structure 2 is horizontally rotatably mounted on the baffle body 1. By rotating the support leg structure 2, it can achieve both folded and unfolded states. This foldable design makes the baffle more convenient to transport and store, and reduces the space occupied.

[0025] Furthermore, a limiting device 4 is provided between the baffle body 1 and the support leg structure 2, which ensures that the support leg structure 2 is in a specific state. Specifically, a rotating seat 13 is fixed on the baffle body 1 and welded to the baffle body 1. The rotating seat 13 is provided with a rotating hole; the support leg structure 2 includes a rotating shaft 21 rotatably installed in the rotating hole and a support leg 22 fixedly installed on the rotating shaft 21. Limiting rings are provided at the upper and lower ends of the rotating shaft 21, thereby restricting the rotating shaft 21 to rotate only within the rotating hole and preventing it from moving up and down. The limiting device 4 includes an elastic pin 41 slidably installed on the side wall of the rotating seat 13 and an ejector spring 42 clamped between the elastic pin 41 and the rotating seat 13 and driving the elastic pin 41 into the rotating hole.

[0026] The installation method of the elastic pin 41: A through hole is provided on the side wall of the rotating seat 13, which connects the rotating hole to the outside. The elastic pin 41 is slidably installed in the through hole, and the inner end of the elastic pin 41 can be inserted into the rotating hole. The diameter of one end of the elastic pin 41 is smaller than the diameter of the through hole, and a plug is fixedly installed on the outer end of the through hole. The plug has a small hole for the outer end of the elastic pin 41 to extend out of the rotating seat 13. The ejector spring 42 is sleeved on one end of the outer end of the elastic pin 41 and clamped between the inner end of the elastic pin 41 and the plug. Under the action of the ejector spring 42, the inner end of the elastic pin 41 is inserted into the rotating hole. The rotating shaft 21 is provided with a positioning hole 43 for the elastic pin 41 to be inserted. The positioning hole 43 is set according to the folded or unfolded state of the support leg structure 2. When the elastic pin 41 is inserted into a positioning hole 43, the rotating shaft 21 is locked in that position. When it is necessary to unlock, the inner end of the elastic pin 41 is disengaged from the positioning hole 43 by pulling the outer end of the elastic pin 41, and the leg structure 2 can be rotated to complete the unlocking.

[0027] To allow the leg structure 2 to rotate in either direction when folded, two positioning holes 43 are provided in the folded state, located on opposite sides of the pivot 21. This limiting device 4 ensures that the leg structure 2 remains stable in both unfolded and folded states, preventing it from rotating arbitrarily.

[0028] The support leg 22 includes a horizontal support leg 221 and an oblique support leg 222 connected to each other, and an anchor hole 223 located at the intersection of the horizontal support leg 221 and the oblique support leg 222. The other end of the horizontal support leg 221 is fixed to the bottom of the rotating shaft 21, with its axis perpendicular to the central axis of the rotating shaft 21. The other end of the oblique support leg 222 is fixed to the top of the rotating shaft 21. The rotating shaft 21, the horizontal support leg 221, and the oblique support leg 222 form a right-angled triangle structure. This right-angled triangle structure of the support leg 22 provides high stability and effectively fixes the baffle body 1 to the ground. The anchor hole 223 facilitates further fixing of the support leg 22 by means of ground anchors, improving the reliability of the support. By inserting anchor rods into the anchor holes, the support leg 22 is fixed to the ground, preventing its movement.

[0029] like Figure 2 , Figure 6 and Figure 7 As shown, the pin structure 3 includes a male connector 31 fixed to one end of the baffle body 1 and a female connector 32 fixed to the other end of the baffle body 1 and mating with the male connector 31. When two baffle bodies 1 are joined end to end, the male connector 31 at the joining end can be inserted into the corresponding female connector 32, fixing the two adjacent baffle bodies 1 together. This pin-type connection method is simple and quick, greatly improving the efficiency of baffle assembly and disassembly and reducing construction time.

[0030] The male connector structure 31 includes a fixing box 311 fixed to the baffle body 1 and a plug 312 slidably installed within the fixing box 311. The fixing box 311 is tightly attached to the baffle body 1 and is welded to the baffle body 1. A limiting hole 313 is provided on the side wall of the fixing box 311. The limiting hole 313 is a horizontally arranged elongated hole. A limiting post 314 is provided on the plug 312. The limiting post 314 extends out of the limiting hole 313 and slides along the limiting hole 313. By manually moving the limiting post 314, the limiting post 314 can be controlled to slide horizontally along the limiting hole 313, thereby controlling the plug 312 to extend or retract into the fixing box 311. The plug 312 has a cuboid structure, and its protruding end is provided with a guide bevel, which facilitates its insertion into the female connector structure 32.

[0031] The female connector structure 32 includes a socket fixed to the baffle body 1. The socket is closely attached to the baffle body 1 and is welded to the baffle body 1. The socket is provided with a socket 321 for inserting the plug 312. When the plug 312 extends out of the fixing box 311, the plug 312 is inserted into the socket 321.

[0032] To prevent the plug 312 from detaching unnecessarily, downward-bent arc-shaped holes 315 are provided at both ends of the limiting hole 313; the limiting post 314 is slidably mounted on the plug 312. Specifically, the plug 312 has a vertically opening sliding hole 316, and the limiting post 314 is slidably mounted within the sliding hole 316. The cooperation between the arc-shaped hole 315 and the sliding hole 316 limits the positioning of the limiting post 314. When the limiting post 314 is located within the arc-shaped hole 315, the plug 312 is in a stable state, preventing the plug 312 from accidentally retracting or extending during connection, thus improving the reliability of the connection.

[0033] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
