In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-4In this embodiment of the present invention, a precast concrete composite box girder includes a fixing plate 1. The upper surface of the fixing plate 1 is provided with connecting holes 16. Each connecting hole 16 is fixedly connected to a support column 2. The top ends of the two support columns 2 are fixedly connected to a placement plate 3. The upper surface of the placement plate 3 is fixedly connected to two connecting plates 5. A clamping plate 7 is placed on the upper surface of the placement plate 3. Each clamping plate 7 has a connecting groove 10 on one side that is close to each other. A positioning plate 11 is slidably connected inside each connecting groove 10. The front and back sides of the positioning plate 11 are fixedly connected to the side that is close to each other of the connecting plate 5, respectively. Electric push rods 17 are fixedly installed on the front and back sides of the two connecting plates 5. The telescopic ends of the two electric push rods 17 are fixedly connected to the front and back sides of the clamping plate 7, respectively.

[0023] Two sets of support plates 4 are fixedly connected to the upper surface of the fixed plate 1. The top of each support plate 4 is fixedly connected to the bottom surface of the placement plate 3. The support plates 4 facilitate the support of the placement plate 3. Two sets of equidistant stabilizing plates 6 are fixedly connected to the upper surface of the placement plate 3. The side of each set of stabilizing plates 6 that is close to each other is fixedly connected to the side of the connecting plate 5 that is far away from each other. The stabilizing plates 6 facilitate the reinforcement of the connecting plate 5. Two sliding sleeves 8 are fixedly embedded on the side of the two connecting plates 5 that is far away from each other. The inner ring of each sliding sleeve 8 is slidably connected to a sliding rod 9. The side of the two sets of sliding rods 9 that is close to each other is fixedly connected to the side of the clamping plate 7 that is far away from each other. The cooperation of the sliding sleeves 8 and the sliding rods 9 facilitates the smoother sliding of the clamping plate 7.

[0024] Two guide grooves 12 are provided on the upper surface of the placement plate 3. Two guide blocks 13 are slidably connected inside each guide groove 12. The top of each guide block 13 is fixedly connected to the bottom surface of the clamping plate 7. The guide grooves 12 and guide blocks 13 make the clamping plate 7 more stable when sliding. A reinforcing ring 14 is fixedly connected to the outer surface of each support column 2. The upper surface of each reinforcing ring 14 is fixedly connected to the bottom surface of the fixing plate 1. The reinforcing ring 14 makes it easier to reinforce the support column 2. Two connecting strips 15 are fixedly connected to the upper surface of the fixing plate 1. The upper surface of each connecting strip 15 is fixedly connected to the bottom surface of the positioning plate 11. The front and back of the two connecting strips 15 are fixedly connected to the side of the connecting plate 5 that are close to each other. The connecting strips 15 make it easier to support the positioning plate 11.

[0025] The working principle of this utility model is as follows: In use, the electric push rod 17 is first connected to the power supply and controlled by the control switch. The support column 2 and the fixed plate 1 are used to support the placement plate 3. The support plate 4 is used to increase the stability of the placement plate 3. When adjusting the clamping plate 7, the electric push rod 17 is activated to bring the clamping plates 7 closer together to adjust their width. Since the sliding sleeve 8 is fixedly embedded at the connecting plate 5 and its inner ring is slidably connected to the sliding rod 9, the stability of the clamping plate 7 is increased. With the help of the guide groove 12 and the guide block 13, the clamping plate 7 can be limited, thereby achieving precise positioning of the concrete composite box girder. The concrete composite box girder can be placed by the cooperation of the connecting groove 10 and the positioning plate 11, thereby increasing the flexibility of the device.
