Description

Technical Field

[0001] This utility model relates to the field of structural reinforcement technology, and in particular to a bridge reinforcement structure. Background Technology

[0002] In existing technologies, many small bridges are experiencing insufficient load-bearing capacity as their service life increases and traffic loads continue to rise. Traditional reinforcement methods, such as thickening the bridge deck pavement or bonding steel plates, have drawbacks such as complex construction, high cost, and increased dead load. In addition, the clearance height under different bridges varies greatly, and there is a lack of a standardized reinforcement device that can flexibly adapt to different terrains and heights and can be installed quickly. Therefore, there is an urgent need for a general-purpose bridge bottom reinforcement structure that is structurally stable, has clear force transmission, and is height-adjustable.

[0003] A search revealed a utility model patent with Chinese patent publication number CN211420911U, which discloses a bridge reinforcement structure including a bridge body and reinforcement components. The reinforcement components are arranged in close contact with the bridge body. The bridge body has a downward-facing lower end face, and the reinforcement components have a reinforcement surface facing the lower end face. Multiple fixing holes are provided on the lower end face, and multiple fixing ribs protrude from the reinforcement surface. The fixing ribs are inserted into the fixing holes, and concrete is poured between the fixing holes and the fixing ribs. By providing multiple fixing holes on the lower end face of the bridge body, providing multiple fixing ribs protruding from the reinforcement surface of the reinforcement components, and arranging the reinforcement components in close contact with the bridge body, and by pouring concrete between the fixing holes and the fixing ribs, the reinforcement components can be securely fixed to the bridge body, while the fixing ribs are hidden inside the fixing holes. However, the aforementioned bridge reinforcement structure has the following shortcomings: Precise drilling is required in the bridge's bottom slab, followed by the insertion of reinforcing bars and the pouring of concrete. This process requires waiting for the concrete to cure and reach its strength, resulting in a long construction period, complex procedures, damage to the original bridge structure, and significant impact on construction quality from site conditions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reinforced bridge structure includes a bridge deck, with bridge feet fixedly connected to both ends of the bridge deck.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] A method for reinforcing bridge structures, such as Figure 1 As shown, the bridge deck 2 includes a bridge foot 1 fixedly connected to both ends of the bridge deck 2. Four fixed steel bars 3 are fixedly connected to the bottom of each of the two bridge feet 1. A truss assembly 4 is fixedly connected to the bottom of the bridge deck 2. Two load-bearing components 5 are fixedly connected to the bottom of the truss assembly 4, and a support component 6 is fixedly connected to the bottom of each of the two load-bearing components 5.

[0021] like Figure 1 and Figure 2 As shown, the truss assembly 4 includes fasteners 41, and three or more fasteners 41 are fixedly connected to the bottom sides of the bridge deck 2, and each of the three or more fasteners 41 is fixedly connected to a connector 42.

[0022] like Figure 1 and Figure 2 As shown, the truss assembly 4 also includes upper chords 46. Two upper chords 46 are fixed to the bottom sides of the bridge deck 2 by three or more connectors 42, and the bottom of each upper chord 46 is fixedly connected to three or more diagonal braces 44.

[0023] like Figure 1 and Figure 2 As shown, three or more of the diagonal bars 44 are connected as one unit by the lower chord bar 45. Four connecting rods 43 are fixedly connected to one side of the circumference of the lower chord bar 45, and two lower chord bars 45 are connected as one unit by the four connecting rods 43.

[0024] Truss assembly 4 is directly fixed to the bottom of bridge deck 2 and is the main load-bearing member. When bridge deck 2 is subjected to pressure and bends downward, the upper chord 46 bears the pressure and prevents bridge deck 2 from deflecting further. The local pressure on bridge deck 2 is converted into multiple points of action through connector 42. Diagonal members 44 connect the upper chord 46 and the lower chord 45, converting the pressure of the upper chord 46 and the tension of the lower chord 45 into their own pressure or tension. These diagonal members 44 divide truss assembly 4 into a series of triangles. By utilizing the stability of triangles, the entire truss undergoes only slight deformation after being compressed, avoiding direct collapse and thus greatly improving the rigidity of the structure.

[0025] like Figure 2 and Figure 3As shown, the load-bearing component 5 includes a first load-bearing rod 52, four first load-bearing rods 52 are fixedly connected to the connecting rod 43, and two second load-bearing rods 53 are fixedly connected to the two lower chord rods 45. Each pair of first load-bearing rods 52 and second load-bearing rods 53 are connected as one unit by a load-bearing ball 51 to concentrate the dispersed force.

[0026] The first load-bearing rod 52 and the second load-bearing rod 53 guide the force from the truss inward; while the key load-bearing ball 51 acts as a spherical junction point, converging the force of all the rods at one point and converting its direction to vertical downward.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, the support assembly 6 includes support rods 62, and two support rods 62 are fixedly connected to the bottom ends of two load-bearing balls 51. The support rods 62 have three or more positioning holes 61, and a sleeve rod 68 is fitted on the circumferential surface of the support rods 62. The top of the circumferential surface of the sleeve rod 68 has a thread 64, and a positioning groove is formed on the circumferential side of the sleeve rod 68 near the thread 64. A fixing hole with the same diameter as the positioning hole 61 is formed in the positioning groove.

[0028] like Figure 4 and Figure 5 As shown, the support assembly 6 also includes a fixing bolt 63, which is threaded into a fixing hole near the positioning groove. The sleeve rod 68 is connected to a fixing sleeve 66 via a thread 64. A support base 65 is fixedly connected to the bottom of the sleeve rod 68, and four support brackets 67 are fixedly connected to the bottom of the support base 65.

[0029] The telescopic sleeve composed of the support rod 62 and the sleeve rod 68 is the main body for height adjustment. By selecting different positioning holes 61 on the support rod 62 and inserting the fixing bolts 63, coarse adjustment can be performed and the sleeve rod 68 can be prevented from sinking. Subsequently, rotating the threaded fixing sleeve 66 to make it press against the bottom of the support rod 62 can achieve fine adjustment and form a friction lock, which, together with the fixing bolts 63, forms a double insurance. Finally, the support base 65 disperses pressure by increasing the contact area, and the support bracket 67 at its bottom ensures stable support of the base and transmits the pressure to the foundation.

[0030] Working principle: When the bridge is subjected to external loads, the load is transferred through the bridge deck 2 to the truss assembly 4 at its bottom. The truss assembly 4 effectively disperses and transfers the concentrated load through the synergistic action of the upper chord 46, diagonal members 44, lower chord 45 and connecting rods 43. The dispersed force then converges to the load-bearing ball 51 of the load-bearing assembly 5 through the first load-bearing member 52 and the second load-bearing member 53, thus integrating the force. Finally, the integrated force is transferred to the support base 65 through the support rod 62 and sleeve rod 68, and further dispersed by the support bracket 67 before being safely and stably transferred to the foundation.

[0031] The support assembly 6 achieves initial height adjustment by sliding the sleeve 68 on the support rod 62. It utilizes multiple positioning holes 61 and fixing bolts 63 to achieve initial positioning and anti-torsion. Finally, by tightening the fixing sleeve 66 and pressing it against the bottom of the support rod 62, a strong frictional force and mechanical stop are formed, thereby achieving height adjustment and rigid fixation. This design allows the structure to adapt to bridges of different heights, ensuring the versatility of the entire device and the convenience of on-site installation.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
