[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The outer arc surface of the longitudinal support steel bar 2 close to the herringbone steel bar frame 31 is fixedly connected with a transverse support steel bar 4 corresponding to the position of the herringbone steel bar frame 31, and the outer arc surface of the transverse support steel bar 4 is fixedly connected to the herringbone steel bar frame 31. The transverse support steel bar 4 is located on the outer arc surface of the longitudinal support steel bar 2 close to the herringbone steel bar frame 31, that is, the transverse support steel bar 4 is located on the upper part of the longitudinal support steel bar 2 to form a stable steel frame structure together, and the outer arc surface of the transverse support steel bar 4 is fixedly connected to the herringbone steel bar frame 31. The herringbone steel bar frame 31 and the transverse support steel bar 4 cooperate to form a triangular structure. The triangular structure makes the structure of the herringbone steel bar frame 31 more stable, enhances the structural strength of the composite plate, and thus enhances the durability of the composite plate, avoiding deformation of the supporting steel frame and causing safety hazards.

[0022] See also Figure 1 and Figure 3 A fireproof layer 6 is fixedly arranged on both sides of the bottom plate body 1. The bottom plate body 1 is usually made of multiple layers of wood or bamboo. Organic substances such as wood and paper are flammable materials. When a fire occurs, it is easy to cause the fire to spread and cause disasters. The setting of the fireproof layer 6 plays a fireproof role.

[0023] In addition, the fireproof layer 6 is a solvent-based coating composed of chlorinated rubber, paraffin and a variety of fireproof additives, which has good fire resistance. When encountering fire, it expands to produce foam and carbonizes into a protective layer to isolate the fire source.

The bottom plate body 1 is usually made of multiple layers of wood or bamboo materials, which is easily affected by moisture during use, causing the bottom plate body 1 to mold and deteriorate, and even rot in severe cases. The fireproof layer 6 plays a waterproof role.

[0025] In addition, the waterproof layer 7 is a higher fatty acid mortar waterproofing agent, which can not only ensure safe construction, but also achieve the effect of waterproofing the back surface.

[0026] The working principle and use process of the utility model are as follows: when in use, the herringbone steel bar frame 31 and the transverse extended steel bar 32 are an integrated structure, and the transverse extended steel bar 32 is located on the outer arc surface of the longitudinal support steel bar 2 away from the herringbone steel bar frame 31, that is, the longitudinal support steel bar 2 is located on the upper part of the transverse extended steel bar 32, and the transverse extended steel bar 32 can be positioned so that the truss steel bar member 3 can be more stably connected to the longitudinal support steel bar 2, instead of being fixed only by welding. The transverse support steel bar 4 is located on the outer arc surface of the longitudinal support steel bar 2 close to the herringbone steel bar frame 31, that is, the transverse support steel bar 4 is located on the upper part of the longitudinal support steel bar 2 to form a stable steel frame structure, and the outer arc surface of the transverse support steel bar 4 is fixedly connected to the herringbone steel bar frame 31, and the herringbone steel bar frame 31 and the transverse support steel bar 4 cooperate to form a triangular structure. The triangular structure makes the structure of the herringbone steel bar frame 31 more stable, enhances the structural strength of the composite plate, and thus enhances the durability of the composite plate, avoids deformation of the supporting steel bar frame, and causes safety hazards.
