Description

Honeycomb core tunnel composite fireproof plate

Technical Field

The utility model belongs to the technical field of the PLASTIC LAMINATED, especially, relate to a compound PLASTIC LAMINATED in honeycomb core tunnel.

Background

The fireproof plate is called high-pressure decorative plate or fireproof plate. Kraft paper is soaked in resin, and is subjected to high-temperature and high-pressure treatment to finally form a surface material for building interior decoration, and generally, the fireproof plate is used for desk walls, cabinets, wall cupboards and the like. With the development of modern technology, more and more fireproof boards are used in the construction field, in various forms, such as wood grain imitation, stone imitation, and metal finish appearing in recent times. In the current day that the awareness of building environmental protection is gradually strong, the use of wood and stone has been limited, but the appearance imitation function of the fireproof board undoubtedly well meets the visual requirement of people. However, the quality of the fireproof board is the most important in engineering construction regardless of changes. The fire-proof plate (fire-proof plate) is made of raw paper through processing melamine resin and phenolic resin, and the main physical properties are shown by the resin characteristics. The phenolic resin has the properties of heat resistance, hardness and the like after thermosetting molding. After the two resins are combined, the fire-proof plate (fire-proof plate) has the performance of both.

Tunnels are a common type of engineering in modern traffic systems. The structure of a tunnel is generally built from reinforced concrete. When the temperature of the concrete reaches 600 ℃, the strength loss of the concrete reaches more than 50 percent. In the environment of 600 ℃, the yield stress of the steel is generally reduced to below 1/3 at the normal temperature. When a fire breaks out in the tunnel, the temperature is generally over 1000 ℃ due to the special structural environment, and the concrete is difficult to bear the high temperature. The high temperature of thousands of degrees can cause the stones inside and outside the tunnel to fly and collapse the severe local arch slabs, which causes serious consequences. The fire protection method for the tunnel concrete structure mainly comprises the steps of spraying fire-proof paint and laying a fire-proof plate. The fireproof coating layer is easy to crack and the material performance is reduced due to factors such as tunnel structure deformation and water leakage, so that the fireproof effect and the service life are influenced, the fireproof protection can be carried out on the concrete structure in the tunnel by laying the fireproof plates on the top surface and the side surface of the concrete structure in the tunnel and the surface of the smoke exhaust pipeline, the fireproof plate can be used as a sacrificial product to improve the fireproof limit of the bearing concrete structure in case of fire, and the fireproof plate has good decorative performance and durability. According to statistics, more than 95% of the urban street-crossing tunnels prepared, constructed and finished at present are planned to be or are protected from fire by using tunnel fire-proof plates, so that the research on the tunnel fire-proof plates is the hot topic in the field of fire-proof building materials at present. At present, the tunnel fireproof plate mainly comprises two main types, namely a silicate inorganic tunnel fireproof plate and a tunnel composite fireproof plate. Although the silicate inorganic tunnel fireproof plate meets certain deformation requirements, the abutted seams and the metal fasteners transfer partial heat to the surface of the structure, so that the surface structure is damaged, and the construction and subsequent maintenance are inconvenient. The tunnel composite fireproof plate is in a flexible installation mode of the metal keel, can effectively absorb harmful factors such as tunnel expansion and contraction, settlement and deformation, so that a fireproof structure attached to the tunnel composite fireproof plate cannot be damaged, the matching surface plate has excellent impact strength and breaking damage resistance load, and can effectively absorb positive and negative pressure shock waves generated when vehicles pass in and out at high speed and meet, and the seam of the surface layer plate is filled with high-temperature-resistant inorganic adhesive, so that the whole fireproof component has no weak point, and the tunnel fireproof grade is more easily improved on the basis of the existing structure. Therefore, the domestic research on the tunnel fireproof plate mainly takes the composite tunnel fireproof plate as a main part.

The tunnel engineering fire protection is the system engineering, and the fire protection design and the quality of the fire protection material are the most critical. The fireproof material suitable for the tunnel engineering at present is an integrated application technology which has various comprehensive effects and is developed only by considering the fireproof performance from the past. The tunnel composite fireproof plate is a product which is researched only in recent years, so that compared with other fireproof plates, the product yield and the production manufacturer are less, but the tunnel composite fireproof plate has an obvious protection effect on a tunnel structure and is suitable for a novel fireproof plate at the current economic development level of China, plays an active role in preventing tunnel fire and improving the fire resistance limit of the tunnel structure when used, and can generate potential and huge economic and social benefits in the aspects of reducing loss caused by external fire and reducing repair cost. Because of tragic training of Chinese and foreign tunnel fires, fire prevention of tunnel structures has attracted high attention of relevant departments at home and abroad, and the requirements of all departments on using tunnel fire-proof plates as the fire protection of the tunnel structures are increasing day by day, the research, production, popularization and application of tunnel composite fire-proof plates are gradually trendy. At present, a plurality of manufacturers and research units in China are actively working on the research and application of the tunnel composite fireproof plate, and with the progress of the work, more and better tunnel composite fireproof plate products can be made out to meet the needs of the society, so that the development of the tunnel composite fireproof plate and the development of a high-performance fireproof auxiliary agent can be promoted, and the tunnel composite fireproof plate can be moved to a good development track.

In a honeycomb structure, the primary function of the honeycomb is to separate the upper and lower panels and to carry transverse shear forces and transfer loads between the panels. According to the molding process of the structure, the molding method of the honeycomb sandwich structure can be divided into a co-curing method and a secondary gluing method, and a gluing co-curing or step-by-step curing molding method can be adopted for the sandwich structure with a complex shape.

The honeycomb core in the middle of the honeycomb structure is mainly shaped like an equilateral triangle, a rhombus, a regular hexagon, a sine curve, a rectangle and the like. The hexagonal honeycomb is simple and convenient to manufacture, saves most materials, and has high structural efficiency, so that the hexagonal honeycomb is most widely applied. The manufacturing method of the regular hexagon honeycomb core mainly comprises two methods of forming and stretching.

Compared with the traditional structure, the honeycomb sandwich structure has the advantages of light weight, high strength, high rigidity, good stability, good fatigue resistance and the like. Under the action of fatigue alternating load, the rigidity, the strength and the service life of the metal structure are rapidly reduced, and the mechanical property and the fatigue property of the honeycomb sandwich structure with the same size are greatly improved. For a structure with a complex stress state, a honeycomb sandwich structure with better fatigue resistance performance is adopted to ensure the reliability and safety of the structure.

Therefore, it is necessary to provide a honeycomb core tunnel composite fireproof plate with good fire blast impact resistance and remarkable fireproof and heat insulation effects.
