DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 3 As shown:

[0029] Embodiment 1: The present invention provides a prestressed mesh steel bar truss composite plate, comprising concrete 1, a prestressed steel bar mechanism 2 and a mesh truss mechanism 3;

[0030] The mesh truss mechanism 3 includes a plurality of sets of frame components 31 arranged in parallel, a plurality of sets of connecting components 32 are welded in parallel inside the plurality of frame components 31, and the frame components 31 and the connecting components 32 are fixed in a grid shape;

[0031] The prestressed steel bar mechanism 2 is completely cast and fixed in the concrete 1 , and the mesh truss mechanism 3 is partially cast and fixed on the upper side of the concrete 1 .

[0032] As can be seen from the above, the prestressed steel bar 2 plays a role in increasing the strength and rigidity of the composite plate. By tensioning the prestressed steel bar 2, prestress can be generated before concrete pouring to enhance the bearing capacity of the composite plate. The prestressed steel bar 2 can significantly improve the crack resistance and durability of the composite plate, reduce the occurrence of cracks, and optimize the stress performance of the composite plate.

[0033] The mesh truss mechanism 3 forms a stable mesh structure through the connection of the skeleton component 31 and the connecting component 32, providing effective structural support for the composite plate.

[0034] like Figures 3 to 7 As shown:

[0035] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the skeleton assembly 31 includes a reinforcing steel bar 1 311, a reinforcing steel bar 2 312 and a connecting rib 313;

[0036] The reinforcing steel bar 1 311 and the reinforcing steel bar 2 312 are arranged in parallel, and the diameter of the reinforcing steel bar 1 311 is larger than that of the reinforcing steel bar 2 312. The reinforcing steel bar 1 311 and the reinforcing steel bar 2 312 are connected to each other through a connecting rib 313. The connecting rib 313 is slidably embedded in a group of reinforcing steel bars 1 311 and reinforcing steel bars 2 312 and then connected by welding.

[0037] Specifically, the connecting rib member 313 includes a group of connecting rib bodies 3131, one end of each group of connecting rib bodies 3131 is fixedly connected to a first steel pipe sleeve 3132, and the other end of each group of connecting rib bodies 3131 is fixedly connected to a second steel pipe sleeve 3133;

[0038] The steel pipe sleeve 1 3132 is limitedly slid on the reinforcing steel bar 2 312, a group of steel pipe sleeve 2 3133 is limitedly slid on the reinforcing steel bar 1 311, the steel pipe sleeve 1 3132 and the reinforcing steel bar 2 312 are welded and fixed, and a group of steel pipe sleeve 2 3133 and the reinforcing steel bar 1 311 are welded and fixed.

[0039] Specifically, the connecting component 32 includes a connecting rib 1 321, a connecting rib 2 322 and a vertical rib 323. The connecting rib 1 321 and the connecting rib 2 322 are arranged parallel to each other. The diameter of the connecting rib 2 322 is larger than that of the connecting rib 1 321. The lower end of the vertical rib 323 is vertically welded and fixed to the connecting rib 1 321, and the upper end of the vertical rib 323 is vertically welded and fixed to the connecting rib 2 322.

[0040] Specifically, the connecting bar 1 321 is vertically welded and fixed to a position where a group of connecting bar bodies 3131 are connected, and the connecting bar 2 322 is vertically welded and fixed to the bottom of the reinforcing steel bar 1 311 .

[0041] As can be seen from the above, the parallel arrangement of the first reinforcing steel bar 311 and the second reinforcing steel bar 312: provides structural stability, ensuring that the entire frame can withstand the expected load; the parallel arrangement simplifies the installation process, making the frame components easier to align and fix;

[0042] The diameter of the reinforcing steel bar 1 311 is larger than that of the reinforcing steel bar 2 312: a more optimized load distribution is achieved by combining steel bars of different diameters; the thicker steel bars provide additional strength support, especially in areas that need to bear greater loads.

[0043] Use of connecting rib 313: The connecting rib effectively connects reinforcing steel bar 1 and reinforcing steel bar 2 together, thereby enhancing the integrity and stability of the skeleton; the connection is made by sliding snap-in and welding, thereby facilitating installation while ensuring the firmness and durability of the connection point; the design of steel pipe sleeve 1 3132 and steel pipe sleeve 2 3133 makes the connection process more flexible and reliable, while providing additional strength support.

[0044] The parallel arrangement of the first connecting rib 321 and the second connecting rib 322 provides structural continuity and ensures a smooth transition between the skeleton components; the parallel arrangement simplifies the connection process and makes the connection components easier to install and align.

[0045] Vertical welding of the vertical ribs 323: The vertical ribs 323 serve as a supporting structure, which enhances the stability and strength of the connecting assembly 32; the vertical welding ensures a firm connection between the vertical ribs 323 and the connecting ribs 1 321 and 2 322, thereby improving the overall stability of the structure.

[0046] like Figure 2 As shown:

[0047] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the prestressed steel bar mechanism 2 includes a plurality of parallel transverse bars 21, a plurality of longitudinal bars 22 are welded in parallel to the upper sides of the transverse bars 21, and a grid is formed between the transverse bars 21 and the longitudinal bars 22.

[0048] From the above, it can be seen that the parallel arrangement of the transverse reinforcement 21: a number of transverse reinforcements are arranged in parallel to form the main transverse support structure of the prestressed reinforcement mechanism; the parallel arrangement ensures the uniform spacing between the transverse reinforcements, thereby improving the stability and bearing capacity of the entire prestressed reinforcement mechanism.

[0049] Parallel welding of longitudinal reinforcement 22: A plurality of longitudinal reinforcements are welded in parallel on the upper side of the transverse reinforcements, forming a grid structure with the transverse reinforcements; the addition of longitudinal reinforcements enhances the longitudinal support capacity of the prestressed reinforcement structure, enabling it to withstand greater loads.

[0050] Grid structure: The transverse and longitudinal bars are arranged in a grid shape. This structural form makes the prestressed steel bar structure stronger and more stable. The grid structure also improves the shear and torsion resistance of the prestressed steel bar structure, enabling it to maintain stable performance under various load conditions.

[0051] Welding connection: The transverse reinforcement and longitudinal reinforcement are connected by welding, which ensures the firmness and durability of the connection point; the welding connection also improves the integrity and rigidity of the prestressed steel bar structure, enabling it to better exert the prestressing effect.
