Embodiment 1

[0050] As shown in the figure, a light-weight, fast-hardening and form-removing-free structural fireproof and thermal insulation prefabricated panel can be directly used as the external formwork of cast-in-place concrete structural engineering, and can be integrally formed into concrete without formwork removal. The surface layer of the structural engineering, including the thermal insulation core layer 3, the lightweight rapid-hardening fireproof layer 4 and at least three layers of reinforced rapid-hardening structure 5, the enhanced rapid-hardening structure 5 includes a reinforcement mesh 6 and a rapid-hardening adhesive mortar layer 7; The enhanced rapid-hardening structure 5 is arranged between the thermal insulation core layer 3 and the light-weight rapid-hardening fireproof layer 4 .

[0051] The inner surface of the thermal insulation core layer 3 is uniformly provided with first grooves 1 along the length direction, and the outer surface of the thermal insulation core...

Embodiment 2

[0070] As shown in the figure, other structures are the same as those in Embodiment 1, and the enhancement network is improved as follows.

[0071] The first rapid-hardening reinforcement structure 10 includes a first reinforcement net 10.1 and a first rapid-hardening adhesive mortar layer 10.2, the first reinforcement net 10.1 is a three-dimensional net 11, and the three-dimensional net 11 includes a bottom line net 12 and an upper line Net 13, the nodes of the bottom line net 12 and the surface line net 13 are fixedly connected with vertical ribs 14. The three-dimensional net 11 can be a net woven with high-strength engineering plastic fiber bundles, and the vertical ribs 14 have a certain rigidity and can support the space of the required three-dimensional net so as to fill the rapid-hardening adhesive mortar layer. The bottom line net 12 is located on the inner surface of the heat preservation core layer 3; the surface line net 13 is 3-6mm away from the outer surface of th...

Embodiment 3

[0085] The upper and lower surfaces of the thermal insulation core layer 3 are bonded and fixed with aluminum foil 17, and the aluminum foil 17 also passes through and covers the inner surface of the second groove. The thickness of the aluminum foil 17 is preferably 0.5-2 mm, because the second groove The groove is in a concave shape with a large inside and a small outside, which enables the insulation board with aluminum foil and the reinforced rapid hardening structure to be integrated with high strength. At the same time, the fireproof performance of the thermal insulation board is greatly enhanced, and the thermal conductivity is also greatly reduced. The thermal conductivity of the light-weight, fast-hardening and form-removing-free structural fireproof and thermal insulation prefabricated panel is as low as 0.01W / (m·K).

[0086] Further, at least one layer of fiber prepreg is bonded and fixed on the outside of the aluminum foil; the fiber prepreg is bidirectional carbon f...

Abstract

Provided is a lightweight rapid-hardening structural fireproofing thermal-insulation prefabricated slab free of formwork removing. The structural fireproofing thermal-insulation prefabricated slab can be directly used as an exterior formwork of cast-in-situ concrete structural engineering, is free of formwork removing, and can be integrally formed to be a surface layer of the concrete structural engineering. The structural fireproofing thermal-insulation prefabricated slab comprises a thermal-insulation core layer (3), a lightweight rapid-hardening fireproofing layer (4) and at least three layers of strengthening and rapid-hardening structures (5). The strengthening and rapid-hardening structures comprise strengthening nets (6) and rapid-hardening bonding mortar layers (7); first grooves (1) are formed in the inner surface of the thermal-insulation core layer at intervals in the length direction, and second grooves (2) are formed in the outer surface of the thermal-insulation core layer at intervals in the length direction; and reinforcing rib bundles (18) are arranged in at least parts of the first grooves and the second grooves, and mortar of the corresponding rapid-hardening bonding mortar layers enters the first grooves and the second grooves in a compacted mode to form rapid-hardening reinforcing ribs (16) which are integrally solidified with the strengthening and rapid-hardening structures. According to the structural fireproofing thermal-insulation prefabricated slab, the thermal insulation function and the formwork function are combined to be a whole, the production efficiency is improved by 3-4 times, the weight of the same thickness is lowered by 40-50%, and the durability is obviously improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to a lightweight, quick-hardening and formwork-free structural thermal insulation and fireproof prefabricated board and a manufacturing method thereof. Background technique [0002] The external wall insulation board is composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials. And other functions in one. Factory production, on-site bonding construction, is the preferred material to meet the current energy-saving needs of housing construction, improve the thermal insulation level of industrial and civil building exterior walls, and is also the preferred material for energy-saving renovation of existing buildings. The wall insulation materials commonly used in my country are extremely flammable. How to combine the high efficiency and energy saving of insulation materials with ...
