Description
Technical Field
The utility model relates to a modified fire prevention heat preservation floor structure of homogeneity.
Background
In recent years, a huge amount of external thermal insulation systems for external walls are constructed in China, wherein organic thermal insulation materials are mainly used, and certain achievement is achieved in the aspect of building energy conservation. However, the successive fire breaks out the alarm clock, so that the fire protection problem of buildings, especially the fire protection problem of external wall external heat insulation, is highly regarded. In 2009, 9 months, ministry of public security, housing and urban and rural construction released regulations on exterior insulation systems and exterior wall decoration and fire prevention for civil buildings (No. 2009] 46). 14 days 3 and 2011, the fire department of the ministry of public security issues a notice about further clarifying the requirements of the fire-fighting supervision and management of the civil building heat-insulating material. The notification requires that "before the release of the new standard, the second regulation of the temporary regulations on external thermal insulation systems and external wall decoration fire prevention (official general characters 2009] 46) is strictly executed, and the external thermal insulation material for civil buildings is a material with combustion performance of class a".
The mandatory provision of these documents places great constraints on the use of organic insulating materials. Therefore, people begin to find and develop heat insulation materials capable of meeting the requirements of inorganic non-combustible performance on one hand, and people further develop and apply the outer wall outer heat insulation system which is applied in the past and can meet the A-grade non-combustible material on the other hand. In the former case, the rock wool board external thermal insulation system technology is in the process of production, and is rapidly applied in large quantities, and occupies a certain amount of market share. In the latter case, building thermal mortar exterior wall external thermal insulation systems, which have previously had a certain range of application and market share, are further applied, and the share of the occupied market rapidly increases.
In 2013, 20 months 1, the Ministry of housing and urban and rural construction issues a notice on the opinions of implementing the State Council on strengthening and improving fire-fighting works, and stipulates that the combustion performance of the external thermal insulation material for civil buildings is preferably grade A and should not be lower than grade B2. Thus, although the heat insulating material having a grade B2 in combustion performance has been applied to the exterior wall surface, fire departments in many places have not been released in the acceptance of completion, and thus the heat insulating material for the exterior wall, which can be a grade a non-combustible material, still has a large application market.
Meanwhile, the existing heat-insulating floor slab structure has the problems of water resistance, moisture resistance and insufficient heat-insulating effect because the design is not reasonable enough.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a modified fire prevention heat preservation floor structure of homogeneity solves current heat preservation floor structure because the design is reasonable inadequately, has that dampproofing and waterproofing performance is relatively poor, keeps warm the not good enough problem of effect simultaneously.
The utility model provides a technical scheme that its technical problem adopted is: a homogeneous modified fireproof heat-preservation floor slab structure comprises a reinforced concrete floor slab, wherein a group of heat-preservation units which are arranged in close proximity to each other are arranged on the upper surface of the reinforced concrete floor slab, and each heat-preservation unit comprises a leveling layer, a waterproof and moistureproof layer, a heat-preservation layer, a moistureproof layer, a protective layer, a plastering layer and a finishing layer which are sequentially arranged from bottom to top on the upper surface of the reinforced concrete floor slab; the leveling layer is composed of cement mortar, and the heat-insulating layer is composed of a fireproof heat-insulating plate.
Furthermore, the protective layer is composed of fine stone concrete and a steel wire mesh.
Furthermore, the waterproof and moistureproof layer is made of waterproof materials, and the heat preservation layer is made of homogeneous modified fireproof heat preservation plates.
Further, the rendering coat comprises rendering coat mortar, and the alkaline-resisting fiber screen cloth of a strenghthened type and the alkaline-resisting fiber screen cloth of a general type have been impressed in rendering coat mortar, and the alkaline-resisting fiber screen cloth of strenghthened type arranges in the alkaline-resisting fiber screen cloth of general type inboard, and rendering coat thickness is not less than 15mm, and the overlap joint length of the alkaline-resisting fiber screen cloth of general type is not less than 100mm, and the alkaline-resisting fiber screen cloth of strenghthened type butt joint.
Furthermore, an isolating layer is arranged between the moisture-proof layer and the protective layer.
The utility model has the advantages that: through screed-coat, dampproofing and waterproofing layer, heat preservation, dampproof course, protective layer, rendering coat, the finish coat that sets gradually, effectively improved the dampproofing and waterproofing performance and the thermal insulation performance of floor structure, effectively solved current insulation floor structure because the design is reasonable inadequately, it is relatively poor to have the dampproofing and waterproofing performance, the not good enough problem of heat preservation effect simultaneously.
