Technical Field
The invention belongs to the technical field of village and town buildings, and particularly relates to a composite floor slab suitable for the village and town buildings.
Background
At present, aiming at the current situations that the fire resistance of buildings in villages and small towns is poor and the loss is serious when a fire disaster occurs, the common method for improving the limit fire-resistant time is to adopt a non-combustible material on the building floor and paint fireproof paint, arrange an automatic water spraying fire extinguishing system in the building, arrange an automatic fire alarm system in the building and the like. The traditional fire prevention transformation technologies focus on inflaming retarding or fire source elimination, three most root causes of damage of village houses under the action of fire are ignored, the integrity of a floor slab is poor, lower-layer flame rapidly spreads to a roof through a floor slab gap to cause the fire of a house to be out of control, the back fire surface of the floor slab rapidly rises to ignite combustible materials above the floor slab to cause the fire to be out of control, and the ultimate bearing capacity of the structure under the fire is insufficient. And the manufacturing cost is very high, the technical means is complicated, and the popularization is inconvenient.
Through a large number of surveys and experiments, most of villages and small towns buildings in China are limited by conditions such as construction technology level, building material quality and the like, and the temperature of the back fire surface is rapidly increased in the early stage of a fire, so that other combustible substances which are not directly contacted with a fire source are ignited, and the fire intensity is increased. Another cause of significant loss is the collapse of the building as a whole due to the flame penetrating through the gaps of the wooden boards and igniting the combustible material on the back fire surface and other load-bearing members such as roof boards. Therefore, how to effectively improve the heating speed and the integrity of the back fire surface of the floor slab and the limit bearing capacity of the floor slab, and prolong the spreading time of flame and the collapse time of the floor slab is a key problem in the technical field of rural building fire prevention reconstruction.

2. The outer protection plate is made of wood plates, the reinforcing plate is made of thin steel plates, the formed multilayer composite plate is tightly connected with the wood keels, the ultimate bearing capacity of the floor slab is increased, meanwhile, the ultimate bearing capacity of the floor slab under the action of fire is also improved, and the original appearance of the village and town buildings is kept to the maximum extent due to the fact that the outer surfaces of the wood plates. The multilayer materials are tightly connected to form the composite floor, and the integrity, the heat insulation performance and the mechanical property of the floor are improved, so that the limit fire-resistant time of the village and town buildings under fire is prolonged, and time is won for rescue and escape. The method is economical and applicable, simple in technology, easy to master, convenient to construct, capable of utilizing waste, green and environment-friendly, and capable of being widely applied to houses in villages and small towns. Effectively improves the current situation that the fire resistance of the prior village and town buildings in China is insufficient, and leads the safety condition of the village and town buildings in China to be coordinated with the stably developed rural economy.
3. The thermal insulation and flame retardation layer is formed by filling plastic bottles filled with water into the keels, and filling thermal insulation materials into gaps among the plastic bottles and gaps between the plastic bottles and the reinforcing plate, so that the heating speed of a back fire surface is effectively slowed down, a large amount of water flows out when the plate is damaged, the fire behavior is lightened, precious time is won for rescue and escape, the fire resistance of the houses in villages and small towns is improved to the greatest extent on the basis of economy and practicality, and meanwhile, the waste utilization is energy-saving and environment-friendly, and meets the standards of green buildings.
4. The thin steel plate adopted by the invention ensures that the whole composite floor slab has no gap, ensures the integrity of the composite floor slab, prevents flame from running to the back fire surface of the slab, and avoids other combustible substances from being ignited; the ultimate bearing capacity of the floor plate under fire is improved, so that the ultimate fire-resistant time of the houses in villages and small towns is prolonged; meanwhile, due to the fact that the villages and the towns are inconvenient to communicate, the thin steel plates are adopted to facilitate transportation. The method has the advantages of economical and practical technology, simple technology, easy mastering, convenient construction and convenient material obtaining, retains the original appearance of the buildings in the villages and the towns to the maximum extent, and can be widely applied to the buildings in the villages and the towns.
