It is a building structure composed of walls and floors. The load-bearing walls of the wall panel structure can be made of bricks, blocks, precast or cast-in-place concrete, and can be divided into three categories: mixed structure, prefabricated large panel structure, and cast-in-place wall panel structure according to different materials and construction methods;

[0003] For example, the Chinese patent with the application number 201620305853.0 discloses a honeycomb composite wall panel, which proposes that "it includes two panels, a honeycomb paper core is bonded between the two panels, a waterproof layer is provided between the honeycomb paper core and the panel, a sound insulation material is filled in the core cavity of the honeycomb paper core to form a sound insulation layer, and a flame-retardant layer is provided on the two panels". Although this kind of honeycomb wall panel has the advantages of light weight, low cost, good environmental protection, and strong integrity, it also has waterproof, fireproof performance and sound insulation effect. However, the strength of the wall panel is only supported by the outer panel, and its supporting ability is limited, resulting in insufficient strength of the wall panel. Therefore, the utility model proposes a composite structure of a flame-retardant paper honeycomb core wall panel to solve the above problems. Content of the Utility Model

[0007] Further improvement lies in that: a flame-retardant layer is arranged on the outer side of the outer layer, the material of the flame-retardant layer is set as wood grain paper, and a flame retardant is added inside the wood grain paper.

[0008] A further improvement lies in that sound insulation strips are provided inside the honeycomb paper core, the sound insulation strips are arranged in a diamond structure, and the sound insulation strips are made of sound insulation cotton.

[0009] A further improvement lies in that the side strip is arranged in a convex structure, the outer side of the side strip is snap-connected to one side of the outer layer board, and the material of the side strip is rubber.

[0017] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0018] According to Figures 1-4As shown in the figure, this embodiment proposes a flame-retardant paper honeycomb core wallboard composite structure, including a composite board body 1. Inside the composite board body 1, there is a honeycomb paper core 2. On both sides of the honeycomb paper core 2, outer panels 3 are symmetrically arranged. On both sides of the outer panels 3, side strips 4 are symmetrically arranged. Inside the outer panels 3, a plurality of support rings 7 are fixedly arranged at equal intervals. The material of the support rings 7 is set as elastic spring pieces, and the shape of the support rings 7 is set as an elliptical structure. The composite board body 1 is mainly composed of a honeycomb paper core 2, outer panels 3, and side strips 4. When the composite board body 1 is impacted, the support rings 7 inside the outer panels 3 will deform. Since the support rings 7 are elastic spring pieces, the elastic force generated by their deformation will offset part of the impact force to enhance the strength of the composite board body 1.

[0019] The material of the outer panel 3 is set as aluminum. On both sides of the honeycomb paper core 2, adhesive films 6 are symmetrically arranged. The honeycomb paper core 2 is bonded to the outer panel 3 through the adhesive films 6. The outer panel 3 is made of aluminum, and aluminum has a light weight, relatively high strength, and low cost, making it suitable as the outer board of the composite board body 1. Using the adhesive films 6 to bond the two on both sides of the honeycomb paper core 2 makes the honeycomb paper core 2 and the two outer panels 3 form a whole to complete the assembly of the composite board body 1.

[0020] On the outer side of the outer panel 3, there is a flame-retardant layer 5. The material of the flame-retardant layer 5 is set as wood grain paper, and a flame retardant is added inside the wood grain paper. Bonding the wood grain paper on the outer side of the outer panel 3 can improve the ornamental property of the composite board body 1. The flame retardant can persistently exist inside the wood grain paper and be fully combined with it, so as to play a flame-retardant role during the combustion process. At the same time, the outer panel (3) is a cement pressure board, which has good flame-retardant performance, and its combustion performance can reach A1 level.

[0021] Inside the honeycomb paper core 2, there is a sound insulation strip filled. The sound insulation strip is set as a diamond structure and is made of sound insulation cotton. Sound insulation cotton, such as polyester fiber cotton, centrifugal glass wool, rock wool, etc., contains a large number of tiny connected pores inside. These pores provide a complex channel network for sound waves, enabling sound waves to penetrate deep into the material during propagation. The sound waves will undergo reflections, mutual superpositions, and collisions of countless fibers. During this process, the energy of the sound waves is continuously dispersed and consumed to play a sound insulation role.

[0022] The shape of the side strip 4 is set as a convex structure. The outer side of the side strip 4 is snap-fitted with one side of the outer panel 3. The material of the side strip 4 is set as rubber. The rubber side strip 4 can seal both sides of the outer panel 3 to ensure the sealing of the composite board body 1, and rubber itself has elasticity and also has a shock-absorbing effect.

[0023] One side of the honeycomb paper core 2 is provided with a groove, and a heat insulation layer 8 is embedded inside the groove. The heat insulation layer 8 is made of phenolic foam, which usually has a low thermal conductivity, meaning that they can effectively block the conduction of heat and play a role in heat insulation.

[0024] The composite board body 1 is mainly composed of a honeycomb paper core 2, an outer layer board 3 and side strips 4. When the composite board body 1 is impacted, the support ring 7 inside the outer layer board 3 will deform. Since the support ring 7 is an elastic spring piece, the elastic force generated by its deformation will offset part of the impact force to improve the strength of the composite board body 1. Bonding the wood grain paper on the outside of the outer layer board 3 can improve the ornamental property of the composite board body 1. The flame retardant can persist inside the wood grain paper and be fully combined with it, so as to play a flame retardant role during the combustion process.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
