The protruding parts on both sides are called flanges (i.e., top plates), and the middle part is called beam ribs (i.e., bottom webs). The design concept of T-beam is to remove the concrete in the tensile zone of the rectangular beam that does not contribute to the bending strength, thereby saving concrete and reducing the deadweight of the component while maintaining the original rectangular bending strength, thereby improving the spanning capacity. T-beams are widely used in various building structures, especially in bridge engineering, where they are often used as the main load-bearing structure to form T-beam bridges.

[0077] Step 3, the first-level lifting device 2 drives the lifting plate to lift upward, so that the longitudinal ribs 30 on the conveying wheel 1 are cached in the first-level cache slot 3;

[0078] Step 4, repeating steps 1-3 until a set number of longitudinal ribs 30 are stored in the first-level cache slot 3;

[0081] Step 7, repeat steps 5-6 until all the longitudinal reinforcements 30 on the sides of the bottom web stirrups 20 are installed.

[0082] The bottom reinforcement method includes the following steps:

[0083] Step 1, the bottom longitudinal reinforcement frame 50 at the other end of the bottom web stirrup tire frame 10 transmits the bottom longitudinal reinforcement 30 to the roller 8. When the conveying wheel 1 completes the conveying of the longitudinal reinforcement 30 on the side of the bottom web stirrup 20, the transmission shaft 7 drives the roller 8 to reverse, so as to pass multiple first-section longitudinal reinforcements 30 to the bottom of the bottom web stirrup 20. After the first section of the longitudinal reinforcement 30 is conveyed to the specified position, the second section of the longitudinal reinforcement 30 is manually placed on the conveying wheel 1 of the bottom longitudinal reinforcement frame 50, and the first section of the longitudinal reinforcement 30 is connected to the second section of the longitudinal reinforcement 30; in this embodiment, the cutting of the bottom longitudinal reinforcement 30 can be carried out after the cutting, conveying and caching of the longitudinal reinforcement 30 in the side laying method are completed, thereby saving more time and facilitating the improvement of construction efficiency.

[0084] In this embodiment, a plurality of sections of bottom longitudinal bars 30 are arranged on the bottom longitudinal bar through-bar frame 50. The diameter of the bottom longitudinal bars 30 is larger than that of the side longitudinal bars 30. The bottom longitudinal bars 30 use thicker steel bars to ensure that the steel cage has sufficient strength. The bottom longitudinal bars 30 are extended by welding or mechanical connection.

[0085] In this embodiment, a plurality of conveying rollers 51 are rotatably arranged on the bottom longitudinal reinforcement threading frame 50, and a material storage platform 52 is arranged above the conveying rollers 51. The bottom longitudinal reinforcement 30 is temporarily stored on the material storage platform 52. After the conveying rollers 51 rotate to convey the first section of the bottom longitudinal reinforcement 30 to the set position of the roller 8, the second section of the bottom longitudinal reinforcement 30 on the material storage platform 52 is manually placed on the conveying rollers 51, and the first section of the bottom longitudinal reinforcement 30 is welded to the second section of the bottom longitudinal reinforcement 30. After that, the conveying rollers 51 rotate to convey the second section of the bottom plate longitudinal reinforcement 30 to the bottom of the stirrups, and the above process is repeated until the threading operation of all the bottom longitudinal reinforcements 30 is completed.

[0086] Step 2, when the first longitudinal reinforcement 30 is connected to the second longitudinal reinforcement 30, the unloading, conveying and caching of the longitudinal reinforcement 30 in the side material laying method are carried out synchronously; after the first longitudinal reinforcement 30 is connected to the second longitudinal reinforcement 30, the transmission shaft 7 drives the roller 8 to reverse, and continues to pass the second longitudinal reinforcement 30 to the bottom of the bottom web stirrup 20 until the second longitudinal reinforcement 30 is delivered to the right place;

[0087] Step 3, repeat steps 1-2 until all the bottom longitudinal reinforcements 30 are threaded.

[0088] In this embodiment, the process of threading the bottom longitudinal ribs 30 and the process of laying the side longitudinal ribs 30 can be staggered by utilizing the gap time between the transmissions of the two, so that the same transmission shaft 7 can simultaneously control the rotation of the conveying wheel 1 and the roller 8. The forward and reverse rotations of the transmission shaft 7 allow the conveying wheel 1 and the roller 8 to run in staggered positions, thereby optimizing the construction process of laying the side longitudinal ribs 30 and threading the bottom longitudinal ribs 30, thereby greatly improving construction efficiency and reducing construction costs.
