Description
Technical field
The utility model relates to a kind of concrete prefabricated element, especially a kind of fire-resistant concrete prefabricated element.
Background technique
Concrete refers to the general designation of the cementing integral engineered composite material of aggregate by cementitious material.The coagulation usually said
A native word, which refers to, makees cementitious material, sand, masonry aggregate with cement；Match by a certain percentage with water (additive and admixture can be contained)
Close, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in civil engineering, cement, lime, gypsum
Equal inorganic coagulation materials and water, which mix and stir, makes concrete mix have plasticity；And then it is condensed by chemically and physically chemical action
It hardens and generates intensity.It is, in general, that drinking water can all meet the requirement of concrete mixing water.Excessive acid, alkali, salt in water
With organic matter can all harmful influence be generated on concrete.Aggregate not only has filling effect, but also to the bulk density of concrete, intensity
It is had a major impact with properties such as deformations.Existing refractory concrete be by aggregate, cementing agent, additive three parts by a certain percentage
Special concrete made of mixture is directly poured is made, fire resistance depends primarily on its material, this body structure does not have
Stronger fire resistance.
Utility model content
The utility model provides a kind of refractory concrete prefabricated components, reasonable in design, and inside is filled with carbon dioxide
Gas, when encountering fire, EVA hot-melt adhesive can gradually melt, and internal carbon dioxide gas is released, to play fire extinguishing
Effect.
In order to meet function described above, the utility model provides the following technical solution:
A kind of refractory concrete prefabricated components of the utility model, including the first concrete layer, in first concrete layer
It is provided with the second concrete layer, gas accumulation layer is provided in second concrete layer, is arranged in first concrete layer
There are several air ducts, air duct extends in the gas accumulation layer of the second concrete layer from the surface of the first concrete layer.
As a kind of optimal technical scheme of the utility model, EVA hot-melt adhesive is filled in the air duct.
As a kind of optimal technical scheme of the utility model, carbon dioxide gas is filled in the gas accumulation layer.
As a kind of optimal technical scheme of the utility model, the second concrete layer table is coated with concrete curing
Agent.
The utility model beneficial effect achieved is: it is compact that the structure design of the utility model is reasonable, fills in air duct
There is EVA hot-melt adhesive, air duct is sealed, and the softening point of EVA hot-melt adhesive, when encountering fire, is produced at 100 DEG C or so around fire
Raw temperature can be higher than 100 DEG C, and the EVA hot-melt adhesive in the refractory concrete prefabricated components air duct, which encounters high temperature, at this time to melt
Change, after the hot melt adhesive in air duct is melted, air duct is divulged information, and the gas accumulation layer inside the second concrete layer is in communication with the outside, gas
Carbon dioxide in accumulation layer will be discharged from air duct, and single refractory concrete prefabricated components carbon dioxide content is limited,
But when multiple concrete prefabricated element composition fire prevention systems, more carbon dioxide can be generated in the short time, because of the burning of fire
Need to consume a large amount of oxygen, the release of carbon dioxide at this time can effectively reduce the occupation rate of oxygen in air, limitation fire
The burning in source, to reach the effect of fire resisting fireproof.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the utility model schematic diagram of internal structure；
In figure: 1, the first concrete layer；2, gas accumulation layer；3, the second concrete layer；4, EVA hot-melt adhesive；5, air duct.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figure 1, including the first concrete layer 1, the second coagulation is provided in first concrete layer 1
Soil layer 3 is provided with gas accumulation layer 2 in second concrete layer 3, is provided with several air ducts in first concrete layer 1
5, air duct 5 is in the gas accumulation layer 2 that the surface of the first concrete layer 1 extends to the second concrete layer 3.
In order to keep this kind of refractory concrete prefabricated components easy to use, EVA hot-melt adhesive 4 is filled in the air duct 5, it is described
Carbon dioxide gas is filled in gas accumulation layer 2,3 table of the second concrete layer is coated with concrete curing agent.
The structure design of the utility model is reasonable, and EVA hot-melt adhesive 4 is filled in air duct 5, air duct 5 is sealed, and EVA is warm
The softening point of melten gel 4 is at 100 DEG C or so, and when encountering fire, the temperature generated around fire can be higher than 100 DEG C, this is resistance at this time
EVA hot-melt adhesive 4 in fiery concrete prefabricated element air duct 5, which encounters high temperature, to melt, after the EVA hot-melt adhesive 4 in air duct is melted,
Air duct 5 is divulged information, and the gas accumulation layer 2 inside the second concrete layer 3 is in communication with the outside, and the carbon dioxide in gas accumulation layer 2 is just
It can be discharged from air duct 5, single refractory concrete prefabricated components carbon dioxide content is limited, but multiple concrete prefabricated elements
Fire prevention system is formed, when encountering fire source, a large amount of carbon dioxide is released in gas accumulation layer 2 in the short time, because fire
Burning needs to consume a large amount of oxygen, and the release of carbon dioxide at this time can effectively reduce the occupation rate of oxygen in air, limit
The burning of fire source processed, to reach the effect of fire resisting fireproof.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
