[0001] This invention relates to the field of prefabricated bridge construction, and more specifically to an assembled bridge module and its processing method. Background Technology

[0002] Prefabricated Bridge Element and System (PBES) refers to prefabricated bridge building elements manufactured in a factory, which can be quickly assembled into a complete bridge. PBES technology can significantly reduce construction time and costs, improve construction quality, and reduce traffic disruption. PBES also helps reduce environmental impact and minimize the impact of road construction on surrounding traffic. However, existing concrete bridge modules are connected only by concrete during installation, which results in poor connectivity between modules. Summary of the Invention

[0003] This invention provides a prefabricated bridge module and its processing method, with the aim of producing a more robust prefabricated bridge module with interconnected components.

[0004] The above objectives are achieved through the following technical solutions:

[0006] Step 1: Place the vertical and horizontal reinforcing bars into the processing mechanism;

[0007] Step 2: Drive the processing mechanism to process the vertical and horizontal steel bars into a steel mesh;

[0008] Step 3: Mix an appropriate amount of water, 10% cement, 40% sand and 50% gravel to form concrete;

[0009] Step 4: Pour concrete into the steel mesh.

[0010] It also includes vertical and horizontal reinforcing bars, each of which is fixed with wire, and each of which has bends in different directions at both ends.

[0011] The processing mechanism includes a support frame with two conveyor shafts rotatably connected to it. Both ends of the two conveyor shafts are connected by belts. Each conveyor shaft is equipped with multiple clamping wheels. The support frame is also rotatably connected to a rotating shaft with two turntables. Two insert rods are slidably connected between the two turntables.

[0012] The processing mechanism also includes two reversing shafts, each of which is rotatably connected to the bracket, and the two reversing shafts are connected by friction belt transmission.

[0013] The processing mechanism also includes two threaded rods, each of which is slidably connected to the bracket. A pull plate is fixedly connected to the front end of the two threaded rods, and multiple fixing piles are fixedly connected to the pull plate.

[0014] The processing mechanism also includes two first gears, which are fixedly connected to two reversing shafts respectively. Each first gear is rotatably connected to the bracket. Each first gear is meshed with a second gear, and each second gear is threadedly connected to a corresponding threaded rod. Attached Figure Description

They are only for the convenience of describing this invention 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 invention.

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1 A method for manufacturing prefabricated bridge modules includes the following steps:

[0030] Step 1: Place the vertical reinforcing bar 16 and the horizontal reinforcing bar 17 into the processing mechanism;

[0031] Step 2: Drive the processing mechanism to process the vertical steel bar 16 and the horizontal steel bar 17 into a steel mesh;

[0032] Step 3: Mix an appropriate amount of water, 10% cement, 40% sand and 50% gravel to form concrete;

[0033] Step 4: Pour concrete into the steel mesh.

[0034] like Figure 2 To achieve a more stable connection between modules;

[0035] A prefabricated bridge module includes vertical reinforcing bars 16 and horizontal reinforcing bars 17, each fixed together with wire. Both ends of each vertical reinforcing bar 16 and horizontal reinforcing bar 17 have bends in different directions. Adjacent horizontal reinforcing bars 17 are arranged in a crisscross pattern, thus ensuring a more stable connection with the vertical reinforcing bars 16 and preventing breakage between upper and lower modules. During bridge module installation, the vertical reinforcing bars 16 between every two modules are hooked together end-to-end, and adjacent horizontal reinforcing bars 17 are hooked together using bends. Concrete is then added to the connection points of each module, allowing the concrete at the connection points of adjacent modules to be supported by the hooked reinforcing bars, thereby increasing the stability of the connection between modules.

[0036] like Figure 3 and Figure 4 To achieve the purpose of bending both ends of the vertical reinforcing bars;

[0037] The processing mechanism includes a support 11, two conveyor shafts 101 are rotatably connected to the support 11, and both ends of the two conveyor shafts 101 are connected by belts. Each conveyor shaft 101 is provided with multiple clamping wheels. The support 11 has a rotating shaft 102 rotatably connected to the support 11. The rotating shaft 102 is provided with two turntables, and two insert rods 103 are slidably connected between the two turntables.

[0038] The vertical reinforcing bar 16 is clamped between the clamping wheels of two conveying shafts 101. A first motor is fixedly connected to one of the conveying shafts 101, driving the first motor to rotate, thereby moving the vertical reinforcing bar 16 forward. The bracket 11 has holes corresponding to the number of clamping wheels, and the clamping wheels drive the reinforcing bar through the holes to the turntable. A plug rod 103 is inserted into the turntable. A second motor is fixedly connected to the rotating shaft 102, driving the second motor to rotate 180°, thereby driving the rotating shaft 102 to rotate, and thus driving the turntable to rotate. The plug rod 103 rotates relative to the rotating shaft 102, thereby bending the front end of the vertical reinforcing bar 16 by 180°. Then the plug rod 103 is removed. When the vertical reinforcing bar 16 moves to the end, another plug rod 103 is inserted, and then the second motor is driven to rotate 180° in the opposite direction, thereby bending the end of the vertical reinforcing bar 16.

[0039] like Figure 4 and Figure 5 To achieve the purpose of making the two ends of the vertical steel bar 16 bend in different directions;

[0040] Two reversing shafts 104 are rotatably connected to the bracket 11, and the friction belt 105 is driven between the two reversing shafts 104.

[0041] The drive shaft 104 rotates, which in turn drives the friction belt 105 to rotate. The upper end of the friction belt 105 contacts the vertical steel bar 16. When the conveying shaft 101 drives the vertical steel bar 16 forward, the friction belt 105 rubs the vertical steel bar 16 to make it rotate, thereby changing the bending direction of the front end of the vertical steel bar 16 to the horizontal direction. This ensures that the bending directions of the front end and the rear end of the vertical steel bar 16 are different when bending the rear end of the vertical steel bar 16, thus enabling the first and second ends of the two vertical steel bars 16 to be hooked together, thereby increasing the stability of the module connection.

[0042] like Figure 6 To achieve the purpose of controlling the movement of the vertical steel bar 16 after the first bend;

[0043] Both threaded rods 202 are slidably connected to the bracket 11, and the pull plate 12 is fixedly connected to the front end of the two threaded rods 202. Multiple fixing piles 201 are fixedly connected to the pull plate 12.

[0044] When the friction band 105 rotates and drives the vertical steel bar 16 to rotate, the front end of the vertical steel bar 16 is blocked by the pull plate 12, which makes it become horizontal. Then the pull plate 12 is driven to move forward, which in turn drives the fixed pile 201 to move forward. When the fixed pile 201 is located at the bend of the vertical steel bar 16, it drives the vertical steel bar 16 to move forward.

[0045] like Figure 7 To ensure that the bend remains horizontal when the vertical reinforcing bar 16 moves;

[0046] The processing mechanism also includes two first gears 106, which are fixedly connected to two reversing shafts 104 respectively. Each first gear 106 is rotatably connected to the bracket 11. Each first gear 106 is meshed with a second gear 203, and each second gear 203 is threadedly connected to the corresponding threaded rod 202.

[0047] A third motor is fixedly connected to one of the reversing shafts 104. The third motor drives the reversing shaft 104 to rotate, which in turn drives the first gear 106 to rotate. The first gear 106 meshes with the second gear 203 to rotate, which in turn drives the threaded rod 202 to move forward. This ensures that the reversing shaft 104 is constantly rotating when the pull plate 12 moves forward. This causes the friction belt 105 to constantly rub against the vertical steel bar 16, thus avoiding the rotation caused by the vibration of the horizontal steel bar 17 bending during the movement of the vertical steel bar 16. This would prevent the bending direction of one end of the vertical steel bar 16 from being inconsistent, which would affect subsequent installation.

[0048] like Figure 8 and Figure 9 This is to achieve the purpose of bending one end of the horizontal steel bar;

[0049] The processing mechanism also includes a lifting platform 13, with a first bending disc 301 rotatably connected to the left end of the lifting platform 13. A metal column is fixed at the center and eccentric position of the first bending disc 301, and multiple limiting wheels 304 are rotatably connected to the lifting platform 13.

[0050] Initially, the metal column at the eccentric position of the first bending disc 301 is positioned above. The horizontal reinforcing bar 17 is inserted between the two metal columns. Then, the first turntable 301 is driven to rotate, thereby bending the end of the horizontal reinforcing bar 17. It then moves forward together with the vertical reinforcing bar 16. The bent end is separated from the two metal columns. At the same time, the limiting wheel 304 supports the horizontal reinforcing bar 17 upward to prevent it from tilting when it is inserted to the other end.

[0051] like Figure 9 and Figure 10 To achieve the purpose of alternating horizontal reinforcing bars with vertical reinforcing bars;

[0052] The processing mechanism also includes a second bending disc 302, which is rotatably connected to the right end of the lifting platform 13. A metal column is fixed at the eccentric position of the second bending disc 302, and two hydraulic cylinders 305 are fixed at the lower end of the lifting platform 13.

[0053] After a horizontal reinforcing bar 17 is tied to a vertical reinforcing bar 16, the hydraulic cylinder 305 is driven to retract. This causes the lifting platform 13 to descend, positioning the limit wheel 304 below the vertical reinforcing bar 16. The above method is then repeated, so that adjacent horizontal reinforcing bars 17 are alternately positioned on the vertical reinforcing bar 16.

[0054] like Figure 9 and Figure 10 This is for the purpose of bending the other end of the horizontal reinforcing bar;

[0055] The processing mechanism also includes a telescopic shaft 303, which is keyed to the second bending disc 302 and slidably connected to the lifting platform 13.

[0056] The other end of the horizontal reinforcing bar 17 is inserted between the telescopic shaft 303 and the second bending disc 302. A fourth rotary motor is fixedly connected to the telescopic shaft 303. The fourth rotary motor drives the second bending disc 302 to rotate. The metal column at the eccentric position of the second bending disc 302 then bends the other end of the horizontal reinforcing bar 17. At the same time, in order to prevent the telescopic shaft 303 from obstructing the movement of the horizontal reinforcing bar 17, the telescopic shaft 303 is driven to retract after bending, thereby ensuring that the horizontal reinforcing bar 17 can move forward.

[0057] like Figure 11 To achieve the purpose of binding the vertical and horizontal reinforcing bars together;

[0058] The processing mechanism also includes two chain wheels 15, both of which are keyed to the telescopic shaft 303. Each chain wheel 15 is engaged with a chain 501, and each chain 501 is engaged with multiple turning wheels 502. The lower chain wheel 15 and the turning wheels 502 are rotatably connected to the lifting platform 13, and the upper chain wheel 15 and the turning wheels 502 are rotatably connected to the bracket 11. A wire box 503 is fixedly attached to the bracket 11.

[0059] The twisting wheel 502 has two wire holes, and the wire box 503 has a through hole corresponding to the wire holes. The wire slides out of the wire box 503, passes through the upper twisting wheel 502, and falls into the lower twisting wheel 502. When the fourth rotary motor drives the telescopic shaft 303 to rotate, the telescopic shaft 303 drives the chain wheel 15 to rotate, which in turn drives the twisting wheel 502 to rotate through the chain 501. The upper and lower twisting wheels 502 twist the wire into a spiral shape by rotating, thereby binding the vertical steel bar 16 and the horizontal steel bar 17 together. Then the horizontal steel bar 17 moves forward with the vertical steel bar 16. After that, the new wire slides out of the wire box 503 and falls into the wire hole of the twisting wheel 502. The diameter of the chain wheel 15 should be 4-6 times the diameter of the twisting wheel 502, so that when the telescopic shaft 303 rotates and drives the second bending disc 302 to rotate 180 degrees, the wire can be fixed between the horizontal steel bar 17 and the vertical steel bar 16 to prevent it from falling off.
