A connecting bar 4 is arranged between the high beam longitudinal reinforcement 1 and the low beam longitudinal reinforcement 2 located below. Both ends of the connecting bar 4 are fixedly connected to the high beam longitudinal reinforcement 1 and the low beam longitudinal reinforcement 2 through a connecting piece 5 respectively. By adopting the above technical solution, the high beam longitudinal reinforcements 1 and the low beam longitudinal reinforcements 2 extending into the support in the beam bodies on both sides can be connected to each other by the day-shaped stirrup 3, and at the same time, the high beam longitudinal reinforcement 1 and the low beam longitudinal reinforcement 2 at the bottom are connected to each other by the connecting bar 4 to form a stable steel bar framework, enhancing the stability and bearing capacity of the middle support and improving the overall safety of the structure.
[0031] In addition, a positioning member 31 and a limiting member 32 are fixedly arranged on the day-shaped stirrup 3. The high beam longitudinal reinforcement 1 and the low beam longitudinal reinforcement 2 located above are lapped on the limiting member 32, and the low beam longitudinal reinforcement 2 located below is clamped in the positioning member 31.

[0032] Refer to Figure 3, the rectangular stirrup 3 includes an outer stirrup 301, and a horizontal connecting bar 302 is fixedly arranged at a position below the outer stirrup 301. By adopting the above technical solution, the outer stirrup 301 can hoop all the high beam longitudinal bars 1 and the low beam longitudinal bars 2 at the upper part, and then cooperate with the horizontal connecting bar 302 to hoop the low beam longitudinal bars 2 at the lower part, so as to realize the connection between the high beam longitudinal bars 1 and the low beam longitudinal bars 2, which is beneficial to forming a stable steel bar framework.
[0033] Refer to Figure 4 , the high beam longitudinal bar 1 includes a first horizontal section 11, the end of the first horizontal section 11 is bent upwards by 90 degrees to form a vertical section 12, and the end of the vertical section 12 is bent to form a first end hook 13.

A third anti-slip groove 55 is formed in the clamping groove 53. By adopting the above technical solution, the fork heads 52 can respectively fix the steel bar structures on both sides, so as to realize the auxiliary fixed connection between the connecting bars 4 and the longitudinal bars 1 of the upper beam and the longitudinal bars 2 of the lower beam, which is convenient for the subsequent binding work with iron wires.
[0036] Working principle: When arranging steel bars, the longitudinal bars 1 of the upper beam and the longitudinal bars 2 of the lower beam extending into the bearing in the two side beams can be connected to each other by the U-shaped stirrups 3 in the shape of a "day".

At the same time, the connecting bars 4 connect the longitudinal bars 1 of the lower beam and the longitudinal bars 2 of the lower beam at the bottom. The above structural form can form a stable steel bar framework, enhance the stability and bearing capacity of the middle bearing, and improve the overall safety of the structure.
[0037] At the same time, during the process of arranging steel bars, when laying the longitudinal bars 2 of the lower beam, they are clamped between the clamping plates 311 of the positioning member 31, which is convenient for the positioning and fixing of this part of the longitudinal bars 2 of the lower beam, and improves the efficiency and quality of binding and fixing; moreover, the outer extension rod 321 of the limiting member 32 can suspend the longitudinal bars 1 of the upper beam and the longitudinal bars 2 of the lower beam, which is convenient for their positioning and fixing, and improves the efficiency and quality of binding and fixing; furthermore, the fork heads 52 of the connecting member 5 can respectively fix the steel bar structures on both sides, playing a role of auxiliary fixed connection. In summary, due to the existence of the positioning member 31, the limiting member 32 and the connecting member 5, it can assist in the positioning and fixing of steel bars to a certain extent, reduce the construction difficulty of steel bar laying and binding, and improve the work efficiency.
