The first prefabricated structure can be used as an outer formwork, the second prefabricated structure is used as an inner formwork, the inner formwork and the outer formwork are not needed in the construction process, and the construction period and the cost are shortened. The mortar protective layer is a high-performance mortar factory prefabricated plate, is made of inorganic materials together with concrete, and is bonded with wall concrete into a whole after the first prefabricated structure without the heat insulation layer is poured. The setting mode of the male connecting piece is that the connecting piece and the integrated plate are prefabricated together, so that the working procedure of installing the connecting piece on site is reduced; the setting of wire net and the mode of setting up of wire net and connecting piece are connected public spare and can be played the fastening effect to the wire net to improve the wholeness ability of integration board. The utility model has the function similar to a reinforcing rib through the design of the convex rib.

According to the utility model, through the ingenious design of the groove on the heat-insulating layer, the mortar can fill the groove after the mortar of the protective layer is poured, the mortar filled in the groove forms a rib to play a role similar to a reinforcing rib, the bonding area of the heat-insulating material and the mortar protective layer in the integrated plate can be improved, the breaking strength of the integrated plate is further improved, and the performances of the integrated plate in the aspects of transportation, hoisting crack resistance, pouring flatness and the like are ensured. According to the mould-disassembly-free heat-insulation-structure integrated plate provided by the utility model, the anchor rod penetrates to the outside of the heat insulation layer, so that the anchor rod can extend into the steel bar cage during construction, a wall body and the integrated plate are firmly combined, and the integrated plate is not easy to damage.

According to the mould-disassembly-free heat-insulation-structure integrated plate provided by the utility model, the transition zone is reserved at the edge of the heat insulation layer; optionally, the width of the transition zone is 20-30 mm. The setting of transition zone can reduce the concatenation seam, avoids the fissure of displacement, reduces follow-up rendering coat thickness. The reason is that the common integrated heat-insulating plate on the market is in rigid connection, the splicing seam is large, the staggered seam phenomenon can occur, the wall body needs to be made into a leveling layer, a plastering layer and a facing layer, and the total thickness of the outside mortar reaches about 15 mm. In addition, after the concrete wall is poured, the concrete can also enter the splicing seams to form a heat bridge, and the heat insulation effect is influenced. After the integrated plate is poured, the transition belt is reserved, the heat-preservation integrated plates are flexibly connected, plate seams are small or seamless splicing can be realized, staggered seams can not occur, and the finishing coat can be made only by treating the finishing mortar (with the glass fiber gridding cloth arranged inside) of about 5mm in the follow-up process. The reduction of the thickness of the mortar layer is beneficial to reducing the internal stress and reducing the cracking risk. The transition belt is made of flexible materials and is integrally adhered with the high-strength mortar layer, the outer side of the transition belt is reinforced by the mortar built-in glass fiber net, the surface of the whole wall is protected by plastering mortar, and risks such as falling and the like cannot occur.

According to the formwork-removal-free heat-insulation-structure integrated plate provided by the utility model, the mortar protective layer is prepared from protective-layer mortar with specific composition, the mortar has high compressive strength and high flexural strength (the compressive strength is more than or equal to 70MPa in 3 days, and the flexural strength is more than or equal to 15 MPA), the fluidity is good, namely the mortar is required to be self-leveling, and the mortar has low shrinkage (about 0.05%), so that cracking and warping are prevented. Based on the above requirements, in particular, in order to meet the compressive strength and the flexural strength of the mortar, the mixing amount of the cement needs to be increased; and the cement adopted by the mortar is double-rapid cement, so that the shrinkage rate of the mortar can be obviously reduced. According to the grading principle, technicians calculate through DESIGN EXPERT software, and select 20-40, 40-70 and 70-140 meshes of sand for grading through experimental verification, so that the compressive strength of the mortar is improved, and the fracture resistance of the mortar is guaranteed. In addition, for the application of the mortar, the compressive strength is only the second, and the most important is the flexural strength which is used as a template, the length of the mortar per se reaches more than 3m, the template is longer, and higher flexural strength is a necessary condition for being used as a non-dismantling template, so that the rubber powder is added at the same time, the flexibility of the mortar is improved to a great extent, and the flexural strength of the mortar in 3 days is more than or equal to 15 MPa.
