Description

Technical Field

[0001] This utility model relates to the field of reinforcement structure technology, specifically a highway bridge reinforcement structure. Background Technology

[0002] A bridge is a structure that spans rivers, lakes, oceans, and other bodies of water, providing convenience for vehicles and pedestrians. With the rapid development of the modern transportation industry, the definition of a bridge has also been expanded. Today, bridges are not only used to cross waterways, but also to cross mountain streams, areas with poor geological conditions, or to meet other transportation needs, making transportation more convenient. Bridge pile foundations are the key foundational component of highway bridges. Highway bridge pile foundation reinforcement structures are strengthening measures taken for highway bridge pile foundations, with the aim of improving the load-bearing capacity, stability, and durability of the pile foundations. When reinforcing the pile foundations of highway bridges, existing technologies typically use steel plate hoops to fix the pile foundations. However, this fixing method has some problems. The connection between the steel plate hoops and the pile foundations, especially the welds and bolt connections, are prone to stress concentration. During long-term use, these parts are prone to fatigue cracks, which leads to a gradual decrease in connection strength. Therefore, a highway bridge reinforcement structure is proposed to address the above problems. Utility Model Content

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A highway bridge reinforcement structure includes a foundation 1, pile foundation 2, and pre-embedded bolts 3. The pre-embedded bolts 3 are fixedly connected to a support assembly 5 via pressure caps 4. A fastening assembly 6 is inserted inside the support assembly 5. The support assembly 5 includes a fixed frame plate 51, with a top block 52 fixedly connected to the top of the fixed frame plate 51. The fixed frame plate 51 has a slot 53, an insertion hole 54, and a reserved screw hole 55 on its inner side. The fastening assembly 6 includes a support pressure plate 61, with an extension hole 62 and a dovetail groove 64 on its inner side. A stud 63 is inserted inside the extension hole 62. A spring 65 is fixedly connected to the support pressure plate 61 via the dovetail groove 64. A dovetail block 66 is fixedly connected to the upper end of the spring 65. An arc-shaped clamping plate 67 is fixedly connected to one side of the dovetail block 66. The dovetail block 66 is slidably connected inside the dovetail groove 64. The stud 63 is threadedly connected to the reserved screw hole 55 in the fixed frame plate 51.

[0017] As a further implementation of this scheme, a pre-embedded screw 3 is pre-embedded inside the foundation 1. The pre-embedded screw 3 is inserted into the inside of the insertion hole 54, and the pressure cap 4 is pressed and fixed on the upper end of the fixed frame plate 51. Through the above settings, the position of the fixed frame plate 51 is ensured to be stable during use, reducing the risk of displacement caused by external forces, thereby improving the structural strength and reliability of the entire device. As a further implementation of this scheme, an arc-shaped groove is provided at one end of the fixed frame plate 51, and the fixed frame plate 51 fits against the pile foundation 2. Through the above setting, it not only plays the role of supporting the lower end of the pile foundation 2, but also enables the precise positioning of the fixed frame plate 51. As a further implementation of this scheme, a gap is provided between the top block 52 and the pile foundation 2, and the top of the top block 52 is attached to the bottom of the dovetail block 66. Through the above setting, the position of the dovetail block 66 and the arc-shaped clamp 67 moving downward is limited, and the arc-shaped clamp 67 is facilitated to move towards the pile foundation 2. As a further implementation of this scheme, the support plate 61 is inserted into the slot 53. The end of the support plate 61 near the arc-shaped clamp 67 is inclined. The support plate 61 and the arc-shaped clamp 67 are in close contact. With the above arrangement, when the support plate 61 moves downward, it can squeeze the arc-shaped clamp 67, thereby achieving the effect of tightly adhering the arc-shaped clamp 67 to the pile foundation 2. As a further implementation of this scheme, the dovetail block 66 has an inclined structure, one end of the arc-shaped clamping plate 67 is tightly attached to the outside of the pile foundation 2, multiple arc-shaped clamping plates 67 are fitted together, and the spring 65 is embedded in the dovetail groove 64. A gap is set between the upper end of the dovetail block 66 and the upper end of the dovetail groove 64. Through the above settings, this design not only improves the uniformity of reinforcement, but also effectively prevents stress concentration, significantly reduces the risk of fatigue cracks caused by stress concentration during long-term use, and ensures the durability of reinforcement. The gap set between the upper end of the dovetail block 66 and the upper end of the dovetail groove 64 provides the necessary space for the movement and adjustment of components.

[0018] Workflow: During installation, first, the support component 5 is fixed to the foundation 1. The insertion hole 54 on the fixing plate 51 is aligned with the pre-embedded screw 3, and the pre-embedded screw 3 is inserted into the insertion hole 54. Simultaneously, the arc-shaped groove at one end of the fixing plate 51 fits against the outer side of the pile 2. This fit between the fixing plate 51 and the pile 2 not only provides support for the lower end of the pile 2 but also positions the fixing plate 51. The fixing is achieved by using the pressure cap 4 to secure the pre-embedded screw 3. The plate 51 acts as a clamping agent, and then the supporting plate 61 is inserted into the slot 53. Before this, the elastic tension of the spring 65 keeps the dovetail block 66 in the lower part of the dovetail groove 64. When the bottom end of the arc-shaped clamp 67 is attached to the top end of the top block 52, the supporting plate 61 is pressed down. The top block 52 limits the arc-shaped clamp 67, and the inclined side of the supporting plate 61 squeezes the arc-shaped clamp 67, causing the arc-shaped clamp 67 to move closer to the pile foundation 2. Although the arc-shaped clamp 67 and the top block 52 are still in contact, the supporting plate 67 and the top block 52 are still in contact. Some wear will occur during installation, but this wear does not affect the installation of the arc-shaped clamp 67. If it is difficult to press the support plate 61 downward, it can be tapped with a rubber mallet to move the support plate 61 downward again until the arc-shaped clamp 67 is tightly attached to the pile foundation 2. The stud 63 is inserted into the extension hole 62, and the stud 63 is threaded into the reserved screw hole 55 of the fixed frame plate 51. The support plate 61 and the fixed frame plate 51 are fixed by the stud 63. The support component 5 and the fastening component 6 are fixed in the same way. After installation, since the multiple arc-shaped clamps 67 are arc-shaped, the internal shape formed by the multiple arc-shaped clamps 67 matches the shape of the pile foundation 2. Based on the above principles, the device changes the traditional method of fixing the steel plate hoop to the pile foundation. This installation can prevent stress concentration, not only improving the uniformity of the support and reinforcement of the pile foundation 2, but also significantly reducing fatigue cracks caused by stress concentration during long-term use, ensuring the durability of the reinforcement of the pile foundation 2.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
