Description
Technical Field
The utility model relates to the technical field of building structures in civil engineering, in particular to a novel composite material fireproof integrated plate for a structure.
Background
The cold-bending thin-wall steel structure has the advantages of light weight, convenience in construction and assembly and the like, has better mechanical property, and can be used for bearing structure frameworks of low-rise civil or public buildings. The existing cold-formed thin-wall steel keel in a building structure has poor local stability of cold-formed thin-wall steel with an opening section, and particularly under a high-temperature environment caused by fire, the cold-formed thin-wall steel keel can lose the bearing capacity rapidly due to the softening of steel, so that the building structure is partially or wholly collapsed due to the failure of a vertical bearing member.
The bearing structure in the cold-formed thin-walled steel structure mainly comprises a cold-formed thin-walled steel bearing keel wall, a multi-ribbed beam floor system and a house truss, wherein in order to enhance the seismic performance of the bearing wall and the rigidity of the floor system, the cold-formed thin-walled keel or rib beam is often combined with a structural clad plate for use. The earthquake frequently occurs in China, the building structure needs to have certain earthquake-resistant performance, particularly for a cold-formed thin-walled steel keel wall, in order to resist horizontal force caused by earthquake action, besides adopting structures such as inclined struts, a cladding structure plate with better mechanical property and tensile strength is an earthquake-resistant structural component with simple structure and high efficiency, and meanwhile, the structural plate can also provide out-of-plane support for the cold-formed thin-walled steel keel so as to indirectly improve the ultimate bearing capacity of the keel. The clad plate commonly used in engineering is fiber cement board, oriented structure flakeboard (OSB), ALC board, gypsum board, magnesium plate, calcium silicate board and the like, wherein the fiber cement board and the OSB are commonly used as structural plates.
Among the above-mentioned planking, OSB board tensile strength is better, as the wooden veneer material, its heat-proof quality is limited, and the OSB board not treated with inflaming retarding is flammable material; the traditional fiber cement board has certain tensile property due to fiber reinforcement, and has relatively good heat resistance and heat insulation property, and the board thickness is usually large and the weight is heavier; the ALC board has low density and good fireproof performance, but has large board thickness and low tensile strength, and can not be used as a structural covering board for earthquake resistance particularly in high earthquake intensity areas; gypsum boards, magnesium boards, calcium silicate boards and the like are all fireproof boards with superior performance, have poor mechanical properties and cannot be used as structural covering panels; in addition, soft fire-proof materials such as rock wool boards can only be used as functional filling or sandwich materials for fire protection, heat insulation or sound insulation.
Therefore, when the facing plate is used for resisting earthquake, the structure of the facing plate of the current cold-formed thin-wall steel structure is complex, and the facing plate is usually composed of multiple layers of materials such as structural plates, fireproof cotton, fireproof plates and external decorative plates, and the multiple layers of plates are too thick in total thickness and too heavy in weight, and the connection structure between the multiple layers of plates and the wall keels of the cold-formed thin-wall steel is too complex, self-tapping screws are disordered, and the actual construction and connection reliability cannot be guaranteed.
