Description

Technical Field

[0001] This utility model relates to the field of height restriction frame technology, specifically a height restriction structure for roads and bridges. Background Technology

[0002] Height restriction barriers are generally divided into two types: fixed height restriction barriers and adjustable height restriction barriers. Height restriction barriers are mainly used as portal frames at the entrances of bridges, culverts, and tunnels. They are generally made of welded steel structures and serve to protect bridges, culverts, and tunnels. There are signs on the height restriction barriers indicating the height limit in meters to warn vehicles. The height restriction barrier is usually positioned at the length of one vehicle, which is the maximum length of a vehicle that the culvert is designed to pass through. The width is the same as the width of the culvert, and the height restriction is generally the culvert's net height minus 20 centimeters.

[0003] However, existing height-restricted structures for roads and bridges typically employ a double-frame structure to ensure structural stability. This type of structure consumes more steel, resulting in higher costs. Consequently, repair or replacement costs are also higher in the event of a collision. Furthermore, this type of structure is not easily deformed under impact, which can lead to greater impact on drivers and threaten their lives. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This height-limiting structure for roads and bridges enhances the stability of the overall structure through first and second triangular blocks, ensuring that the structure will not collapse. This height-limiting structure for roads and bridges, through the diagonal tension of the cables, ensures the front-to-back stability of the overall structure while reducing the number of structural components and lowering costs. Therefore, it will not cause excessive damage in the event of a vehicle collision. Furthermore, the cables, when the structure is subjected to a high-speed vehicle impact, will break or shift, causing the overall structure to deflect, thus preventing excessive impact forces on vehicle occupants and avoiding threats to their lives.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0021] A height-limiting structure for road bridges includes a support rod 101. A base plate 102 is fixedly installed at the bottom end of the support rod 101. A diagonal brace 103 is fixedly installed between the base plate 102 and the support rod 101. A fixing hole 104 is provided on the base plate 102. A first hanging ring 105 is fixedly installed on the side of the support rod 101 away from the base plate 102. A cable 106 is fixedly installed inside the first hanging ring 105. A second hanging ring 201 is fixedly installed on the side of the cable 106 away from the first hanging ring 105. A connecting mechanism 202 is provided on the side of the support rod 101 away from the hanging rings.

[0022] The above scheme allows for component support via support rods, and the base plate can be fixed via fixing holes, thus securing the support rods. Diagonal bracing plates create diagonal bracing at the connection points of the support rods, thereby improving the support stability of the support rods. Cables are connected within the first and second hanging rings, which can pull the support rods to maintain their front-to-back stability.

[0023] In this embodiment, preferably, the connecting mechanism 202 includes a connecting rod 203, which is fixedly installed between the support rods 101, and a vertical support rod 204 is fixedly installed between the connecting rods 203.

[0024] The above solution allows the connecting rods to support the support rods and restricts the passage of oversized vehicles. The vertical struts can increase the supporting force between the support rods, enabling the connecting rods to support each other.

[0025] In this embodiment, preferably, a first triangular block 205 is fixedly installed at the outer connection between the connecting rod 203 and the support rod 101, and a first fixing screw 206 is fixedly installed on the first triangular block 205.

[0026] The above solution allows the first triangular block to be fixed by the first fixing screw, thereby creating a diagonal brace between the support rod and the connecting rod, thus ensuring the stability of the connection between the support rod and the connecting rod.

[0027] In this embodiment, preferably, a first corner plate 301 is fixedly installed at the inner connection between the connecting rod 203 and the support rod 101, a first assembly screw 302 is fixedly installed at the connection between the first corner plate 301 and the connecting rod 203, and a first connecting screw 303 is fixedly installed at the connection between the first corner plate 301 and the support rod 101.

[0028] The above solution allows the first corner plate to be fixed at the connection between the connecting rod and the support rod using the first assembly screw and the first connecting screw. The first corner plate can improve the connection stability between the connecting rod and the support rod.

[0029] In this embodiment, preferably, a second triangular block 304 is fixedly installed at the outer connection between the connecting rod 203 and the vertical support rod 204, and a second fixing screw 305 is fixedly installed on the second triangular block 304.

[0030] With the above solution, the second triangular block can be fixed at the connection between the connecting rod and the vertical support rod by the second fixing screw. The second triangular block can generate a diagonal brace at the connection, thereby keeping the connection stable and preventing the connecting rods from swaying.

[0031] In this embodiment, preferably, a second corner connecting plate 306 is fixedly installed at the inner connection between the connecting rod 203 and the vertical support rod 204, a second assembly screw 401 is fixedly installed at the connection between the second corner connecting plate 306 and the connecting rod 203, and a second connecting screw 402 is fixedly installed at the connection between the second corner connecting plate 306 and the vertical support rod 204.

[0032] The above solution allows the second angle connecting plate to be fixed at the connection between the connecting rod and the vertical support rod by means of the second assembly screw and the second connecting screw, thereby improving the connection stability at the connection between the connecting rod and the vertical support rod.

[0033] In this embodiment, a height restriction structure for road bridges is used such that the user fixes the base plate 102 to the cement blocks on both sides of the road through the fixing holes 104, thus securing the entire structure. Then, the user fixes the second hanging ring 201 to another set of cement blocks and connects the first and second hanging ears with the cable 106, generating a pulling force. During this pulling, the structure experiences diagonal tension, ensuring front-to-back stability during height restriction. Meanwhile, the first triangular block 205 provides triangular support between the support rod 101 and the connecting rod 203, stabilizing the connection and thus maintaining lateral stability. Simultaneously, the second triangular block 304 provides support between the connecting rod 203 and the vertical support. The triangular support force generated between the rods 204 strengthens the connection, preventing deformation between the connecting rods 203 and thus preventing the overall structure from swaying left and right, thereby enhancing the overall lateral stability. Therefore, the structure will not collapse after assembly. Furthermore, the diagonal tension of the cable 106 ensures the front-to-back stability of the overall structure while reducing the number of structural components and lowering costs, thus preventing excessive damage in the event of a vehicle collision. Moreover, the cable 106 is fixed in place so that it may break or shift when the structure is subjected to a high-speed vehicle collision, allowing the overall structure to shift, thereby preventing excessive impact forces on vehicle occupants that could threaten their lives.
