[0030] Reference Figures 1-8 As shown, an integrated beam-slab assembly system of prestressed beams and prestressed slabs includes frame columns 1, prestressed main beams 2, prestressed secondary beams 3, precast base slabs 4, and connecting components 5. The frame columns 1 are vertically arranged. The prestressed main beams 2 are located between two adjacent frame columns 1. The prestressed secondary beams 3 are located on two opposing prestressed main beams 2. The precast base slab 4 is laid on the prestressed secondary beams 3 and connected to the prestressed main beams 2. The frame columns 1 are equipped with column caps 11 for supporting the prestressed main beams 2. The connecting components 5 are located between the prestressed main beams 2 and the prestressed slabs 3. Between the prestressed secondary beams 3, the connecting component 5 is provided with a thick steel plate 51, shear reinforcement 52, connecting groove 53, backing plate 54, thick pad plate 55, and mortar pad layer 56. The thick steel plate 51 is provided on both ends of the prestressed secondary beam 3. The shear reinforcement 52 extends into the prestressed secondary beam 3 and is perpendicularly connected to the thick steel plate 51. The connecting groove 53 is provided at the corresponding positions of the prestressed main beam 2 and the prestressed secondary beam 3. The backing plate 54 is provided in the connecting groove 53. The thick pad plate 55 is provided on the bottom surface of the backing plate 54. The mortar pad layer 56 is provided on the thick pad plate 55.

[0031] The frame column 1, prestressed main beam 2, prestressed secondary beam 3, and precast base slab 4 form the basic building structure. The connecting component 5 is connected to the prestressed secondary beam 3 by pressing with the connecting groove 53. The structural components are easy to manufacture and process, the structure is simple, the connection is strong, and the assembly and construction are simple. The rear steel plate and shear reinforcement 52 form good shear tensile strength and support force. The backing plate 54 and the thick pad plate 55 provide high-strength support. The mortar pad layer 56 plays a good leveling role and improves the stability of the entire structure.

[0032] Furthermore, the connecting groove 53 is provided with a tensile groove 57, the backing plate 54 matches the connecting groove 53 and the tensile groove 57, and the thick steel plate 51 is provided in the tensile groove 57.

[0033] The tensile groove 57 serves both a positioning function and a good tensile function, stabilizing the connection between the prestressed main beam 2 and the prestressed secondary beam 3, and improving the stability of the entire structure.

[0034] Furthermore, shear plates 58 are fixed at intervals on the shear reinforcement 52, and the shear plates 58 are arranged perpendicular to or at a certain angle to the shear reinforcement 52.

[0035] The shear plate 58 enhances the tensile strength of each shear reinforcement 52. The vertically positioned shear plate 58 has strong tensile strength, but it is easy for the shear plate 58 to detach from the shear reinforcement 52 and fail. The shear plate 58 positioned at a certain angle provides a certain pressure to the shear reinforcement 52, thereby enhancing the bonding force between the two. The included angle of the shear plate 58 on the same shear reinforcement 52 can be different or the same, and can be obtuse or acute. Similarly, the shear plate 58 on different shear reinforcements 52 can also be set in the same way, thereby enhancing the force in a certain direction or balancing the force in a certain direction.

[0036] Furthermore, the diameter of the shear reinforcement 52 is 20-30mm, the thickness of the thick steel plate 51 is 12-18mm, the thickness of the backing plate 54 is 3-7mm, the thickness of the thick pad plate 55 is 18-24mm, and the thickness of the mortar pad layer 56 is 8-12mm.

[0037] This parameter setting ensures the strength and stability of the entire frame while saving material costs.

[0038] Furthermore, at least one prestressed secondary beam 3 is provided between adjacent prestressed main beams 2. The upper end of the prestressed secondary beam 3 is provided with an I-beam stud 31. The precast base plate 4 is provided with a shear hole 41 corresponding to the I-beam stud 31. The I-beam stud 31 passes through the shear hole 41 and is connected to the precast base plate 4.

[0039] The I-beam stud 31 can improve the connection strength between the prestressed secondary beam 3 and the precast base plate 4.

[0040] Furthermore, the inner side of the prestressed main beam 2 is provided with a corbel 21, and the precast base plate 4 is supported on the corbel 21.

[0041] Furthermore, the thickness of the cow leg 21 is 50mm and the height is 100mm.

[0042] The corbel 21 provides excellent support for the precast base slab 4 and enhances the connection strength of the prestressed main beam 2.

[0043] Furthermore, the precast base slab 4 is provided with a reinforced concrete layer 42, truss reinforcement 43, steel pipe truss 44 and slab top reinforcement 45. The truss reinforcement 43 is wavy, and the lower half of the wavy truss reinforcement 43 is embedded in the reinforced concrete layer 42. The upper ends of adjacent truss reinforcement 43 are connected to the steel pipe truss 44. The slab top reinforcement 45 is vertically provided on the upper and lower sides of the steel pipe truss 44.

[0044] The precast base plate 4 allows for the installation of prestressed secondary beams 3 without the need for support, and reserves structural components such as upper truss reinforcement 43, steel pipe truss 44 and top reinforcement 45 for cast-in-place concrete, thereby improving the overall strength and stability of the structure.

[0045] Furthermore, the precast base plate 4 is provided with a negative bending bar 46, which is symmetrically arranged with the prestressed secondary beam 3; a negative bending bar 47 is provided between the precast base plate 4 and the prestressed main beam 2.

[0046] Negative bending reinforcement 46 and negative bending reinforcement 47 can provide good tensile resistance at the connection support point, preventing deformation or breakage.

[0047] Furthermore, the length of the first negative bending bar 46 is four times the width of the prestressed secondary beam 3, and the length of the second negative bending bar 47 is four times the width of the prestressed main beam 2.

[0048] The length setting ensures tensile strength.

[0049] During construction, frame column 1 is cast-in-place. The first step is to pour frame column 1 and column cap 11. After frame column 1 and column cap 11 reach 100% strength, the second step is to hoist the prestressed main beam 2 on site and place it on the column cap 11. The third step is to hoist the prestressed secondary beam 3 and place it at the connection groove 53 of the prestressed main beam 2. The fourth step is to hoist the precast base slab 4. The fifth step is to place the top reinforcement 45, negative bending reinforcement 1 46, negative bending reinforcement 2 47, and other structural components. The sixth step is to pour the cast-in-place layer. This formwork-free and support-free integrated beam and slab assembly system can achieve support-free spans in conventional projects, ensuring safety and reliability, reducing costs, reducing labor, and achieving rapid assembly. To a certain extent, it leverages the advantages of prefabricated buildings in terms of low cost, high efficiency, and high quality. Compared with steel structures, it saves steel; compared with concrete structures, it saves formwork and supports; and it utilizes a large amount of mechanization, saving labor.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
