[0010] Reference Figure 1 Figure 2 Figure 3 Figure 4 The aforementioned prefabricated reinforced concrete support beam connection structure includes a support device 1, a concrete block 2, connecting devices 3, locking nuts 4, supporting bridge columns 5, diagonal reinforcing bars 6, and pre-embedded reinforcing bars 7. Its characteristic is that: a concrete block 2 is inserted into the middle of the upper surface of the support device 1; several connecting devices 3 are evenly distributed and inserted into the middle of the front and rear surfaces and horizontally of the concrete block 2; a locking nut 4 is inserted into the outer edge of the side surface of each connecting device 3; and a supporting bridge column 5 is connected to the middle of the lower surface of the support device 1. The supporting bridge column 5 has diagonal reinforcing bars 6 symmetrically connected at the middle of the upper part of its left and right side surfaces. Several pre-embedded reinforcing bars 7 are evenly distributed on the lower surface of the supporting bridge column 5. The supporting device 1 includes a base plate 1-1, anti-slip textures 1-2, side plates 1-3, and notches 1-4. Several anti-slip textures 1-2 are provided at the middle of the upper surface of the base plate 1-1. Side plates 1-3 are symmetrically connected at the middle of the front and rear edges of the upper surface of the base plate 1-1. Several notches 1-4 are evenly distributed in a horizontal row at the upper edge of the outer surface of the side plates 1-3. Plate 1-1 is connected to the middle of the upper surface of the supporting bridge column 5. The lower surface of the inner part of the notch 1-4 is arc-shaped. The concrete block 2 includes bridge 2-1, sheet metal 2-2, steel column 2-3, and insert pipe 2-4. Sheet metal 2-2 is connected to the middle of the front and rear surfaces and the upper surface of bridge 2-1. Several steel columns 2-3 are evenly distributed horizontally in the middle of the upper surface of bridge 2-1. Several insert pipes 2-4 are evenly distributed horizontally in the lower part of the front and rear surfaces of bridge 2-1. Bridge 2-1 is inserted into two... Between the side plates 1-3, the connecting device 3 includes a threaded post 3-1, a chuck 3-2, a spring 3-3, and a retaining ring 3-4. The chuck 3-2 is fixedly inserted into the inner side surface of the threaded post 3-1, and the spring 3-3 is connected to the center of the outer side surface of the chuck 3-2. The retaining ring 3-4 is inserted into the outer side surface of the threaded post 3-1. The retaining ring 3-4 is concave in shape. The threaded post 3-1 penetrates the notch 1-4 and is tightened into the insertion tube 2-4. The locking nut 4 is inserted into the threaded post 3-1.

[0011] In use, the workers first place the supporting bridge column 5 on the ground and insert the pre-embedded steel bar 7 into the concrete. Then, the threaded post 3-1 on the connecting device 3 is tightened into the insertion tube 2-4 on the concrete square 2. Next, the workers use a crane to lift the bridge 2-1 and insert it between the side plates 1-3 on the two lifting devices 1, placing it on the upper surface of the base plate 1-1. At the same time, the threaded post 3-1 is inserted into the notch 1-4, and the threaded post 3-1 and the notch 1-4 are aligned. The bridge 2-1 position can be positioned, and the anti-slip texture 1-2 increases the friction between the bridge 2-1 and the base plate 1-1. Then, the retaining ring 3-4 is inserted between the side plate 1-3 and the bridge 2-1 and installed on the threaded post 3-1. At the same time, the inner surface of the retaining ring 3-4 contacts the spring 3-3 and the other side contacts the side plate 1-3. Then, the locking nut 4 is tightened on the outer end of the threaded post 3-1 and fixed to the side plate 1-3. Finally, the bridge deck is placed on the bridge 2-1 and installed on the steel post 2-3.

[0012] The locking nut 4 is T-shaped. The locking nut 4 can squeeze the retaining ring 3-3 and compress the spring 3-3 to better reinforce the bridge 2-1. The elastic force of the spring 3-3 can be calculated based on the weight of the bridge.
