Detailed implementation mode

[0023] The following will further elaborate on this application in conjunction with the attached Figure 1-2 drawings.

[0024] The embodiment of this application discloses a prefabricated structural composite secondary beam.

[0025] Referring to Figure 1 and Figure 2 , a prefabricated structural composite secondary beam includes a secondary beam steel frame 1. The opposite ends of the secondary beam steel frame 1 are welded to two adjacent main structural beams 100 by welding, and the precast floor slab 101 is placed on the secondary beam steel frame 1 by hoisting. A receiving groove 11 is formed on one side of the secondary beam steel frame 1 close to the precast floor slab 101. The receiving groove 11 is provided with an opening facing upward where the precast floor slab 101 is located, and the precast floor slabs 101 are respectively arranged on opposite sides of the opening. Concrete is poured into the receiving groove 11 through the gap between the precast floor slabs 101 and the opening to form a floor slab panel 5 and a secondary beam body 4, so that the three processes of secondary beam construction, precast floor slab 101 construction, and surface layer pouring construction can be combined into one process, greatly improving the construction speed of prefabricated buildings, saving labor and time, and having high connection tightness among the secondary beam body 4, the precast floor slab 101, and the floor slab panel 5.

[0026] To enhance the strength of the secondary beam body 4, this embodiment further includes secondary beam reinforcement 2, which is arranged in the receiving groove 11 and between adjacent precast floor slabs 101. The secondary beam reinforcement 2 includes a first reinforcement 21 and a second reinforcement 22. The first reinforcement 21 is integrally in a U shape. Both ends of the first reinforcement 21 are arranged in the receiving groove 11, and a groove facing the bottom of the receiving groove 11 is provided at the middle position of the first reinforcement 21, and the groove is located in the gap between the two precast floor slabs 101. The second reinforcement 22 is laid on the bottom of the receiving groove 11, and the second reinforcement 22 is located between the first reinforcement 21 and the bottom of the receiving groove 11; at the same time, the second reinforcement 22 is laid on the bottom of the groove. By laying the first steel beam and the second steel beam, the concrete strength at the connection between the secondary beam body 4 and the floor slab panel 5 and the secondary beam body 4 can be improved.

Stud 23 includes a vertical portion and a horizontal portion arranged vertically, wherein the vertical portion is vertically arranged at the bottom of accommodation groove 11 and is located at the central position of the bottom of the groove, and the horizontal portion is located above the vertical portion away from the bottom of accommodation groove 11. The horizontal portion is located between two adjacent precast floor slabs 101 and below the bottom of the groove. By providing stud 23, the strength of secondary beam main body 4 can be further improved.

[0028] Above the precast floor slab 101 away from the secondary beam steel frame 1, a panel steel bar 3 is further laid, and the panel steel bar 3 is located within the floor slab 5, so as to enhance the strength of the floor slab 5 and play a role in preventing the floor slab 5 from cracking as much as possible.

[0029] The implementation principle of the assembled structure combined secondary beam in the embodiment of the present application is as follows: First, connect the secondary beam steel frame 1 to the main structural beam 100 of the assembled structure, and then lay the secondary beam steel bars 2; after laying, place the precast floor slab 101 on the opposite sides of the secondary beam steel frame 1 by hoisting; then, tie the panel steel bars 3; finally, pour concrete at one time through the gaps between the precast floor slabs 101 and pour the concrete into the accommodation groove 11 through the opening to form the floor slab 5 and the secondary beam main body 4, so that the three processes in the prior art can be combined into one process, greatly improving the construction speed of the assembled building.
