Description
Technical Field
The invention belongs to the field of constructional engineering, and particularly relates to an MF heat-insulating sound-insulating fabricated concrete laminated slab.
Background
With the rapid development of the construction industry in China, the nation actively promotes the transformation and the upgrade of the construction industry, and the fabricated building is rapidly developed with good economic, environmental and social benefits. The proportion of building energy consumption in total energy consumption is increased from 10% in 1978 to 38% at present, and the vigorous development of energy-saving buildings is a consensus. With the continuous improvement of the requirements on energy conservation and environmental protection of buildings, the heat preservation technology of building structures is increasingly strengthened, particularly, the heat preservation and sound insulation technology of floor slabs is rapidly developed and becomes an important building energy conservation technology in China.
In the main design specifications of the fabricated concrete structure in China, the concepts of green buildings and sponge cities are compulsorily stipulated. All require heat preservation, fire prevention, sound insulation and other functions to be embodied in the design of the prefabricated part. At present, in engineering practice, the heat preservation and sound insulation technology of a building maintenance structure only stays on an outer wall system, and the most extensive prefabricated composite floor slab still performs secondary heat preservation and sound insulation.
The bottom ribs of at least one direction of the composite slab extend into the laminated layers of the peripheral members to improve the connecting performance and the integrity of the prefabricated composite slab and the structure. However, a large amount of steel bars are usually reserved on the peripheral components of the prefabricated composite slab, and bottom ribs extending out of the side edges of the prefabricated composite slab interfere with the peripheral components in the installation and in-place process of the prefabricated composite slab, so that the installation difficulty of the bottom die of the post-cast strip of the prefabricated composite slab is greatly improved, the construction efficiency is reduced, and the utilization efficiency is low.
Along with the progress of building material technology, MF (mineral wool) insulation boards are greatly developed in the aspect of novel materials, are all called as MF insulation disassembly-free templates, are made of mineral wool and vitrified micro bubbles serving as main raw materials, added with functional additives and processed by a special process, have excellent performances such as ultrahigh strength, high toughness, high impermeability, high corrosion resistance and the like, and are expected to become basic materials for the construction of next-generation infrastructure. The cast-in-place concrete formwork has the function of permanently avoiding formwork disassembly in the construction of a cast-in-place concrete structure (post-cast strip), and is a multifunctional integrated building product integrating the four functions of formwork, heat preservation, sound insulation and fire prevention. However, because the laminated board post-cast strip adopts a secondary formwork, the cast-in-place operation is relatively less. The initial cost of thermal, acoustic and fire protection in floors is extremely high and is less used in fabricated building structures.
Due to the characteristics of the MF insulation board and the advantages of the assembled concrete building structure template, the MF insulation board and the assembled concrete building structure template can be combined to exert the advantages of the MF insulation board and the assembled concrete building structure template to the greatest extent, and related disadvantages are avoided. The demand of combining the heat preservation of the precast concrete laminated bottom plate with the formwork and improving the construction efficiency can be effectively solved through the mode of increasing and combining the MF heat preservation plate and the precast laminated slab, and the invention is provided for the demand.

(4) assembling and combining a plurality of MF heat-insulating small plates by adopting H-shaped grooves according to the drawing size of a component, splicing and flatly laying a combined body of the MF heat-insulating plates and a laminated slab into a mould, binding reinforcing steel bars at the bottom of the laminated slab on the combined body of the MF heat-insulating plates, binding truss reinforcing steel bar meshes, and binding and fixing exposed thread teeth parts of the MF special self-tapping anchor bolts and the bottom reinforcing steel bars by adopting binding wires to form a reliable whole;
(5) if an embedded part or a hole reinforcing steel bar exists, checking a drawing, and pouring concrete after the acceptance of a hidden project is finished; automatically vibrating on a vibration platform, and roughening the top surface;
(6) and finally, entering a curing kiln for steam curing.
