Embodiment 1

[0080] This embodiment provides a formwork-free insulation integrated board, such as figure 1 or 2, comprising: a first prefabricated structure and a second prefabricated structure, the first prefabricated structure comprising:

[0081] The mortar protective layer 3 is provided with several ribs 2 on one side, and the number of ribs in this embodiment is 2;

[0082] Steel wire mesh 4 is arranged inside the mortar protective layer 3;

[0083] Several connecting male parts 5, including the first anchor plate 6 and the first anchor rod 7, the first anchor plate 6 is located on the side of the steel wire mesh 4 away from the rib 2, the first anchor rod 7 penetrates to the mortar protection layer 3 external;

[0084] The second prefabricated structure includes a prefabricated thermal insulation module 10, and several connecting female parts 11 used in conjunction with the connecting male parts.

[0085] Optionally, the number of the ribs 2 can be 2-3, in this embodiment, the num...

Embodiment 2

[0108] This embodiment provides a formwork-free thermal insulation integrated board, including: the structure and preparation method of the integrated board are the same as in Embodiment 1, the difference is that the composition of the powder for preparing the mortar protective layer is different, specifically, in In the present embodiment, the composition of described powder is:

[0109] 400kg of high belite anti-cracking double fast cement; 590kg of sand, including 110kg of 20-40 mesh sand, 320kg of 40-70 mesh sand, 160kg of 70-100 mesh sand; 4.1kg of admixture, including, water reducer ( FOX-C900 model) 2kg, retarder (sodium citrate) 1.2kg, lithium carbonate 0.5kg, Wenlun glue 0.1kg, expansion agent (402 expansion agent produced by Chongqing Yuyuan Building Materials Co., Ltd.) 0.3kg; Dispersible latex powder (5010N) 10kg.

Embodiment 3

[0111] This embodiment provides a formwork-free thermal insulation integrated board. Compared with Embodiment 1, the difference is that the first prefabricated structure also includes a thermal insulation layer 1, and the thermal insulation layer 1 is provided with several grooves. Used to accommodate the rib 2 . The edge of the thermal insulation layer 1 is also provided with a transition zone 9, the width of the transition zone is 30mm, the number of ribs is 3, the height of the ribs is 35mm, and the width is 35mm; the number of the connectors is 6 pcs / square meter.

[0112] The material of the insulation layer can be rock wool board and its composite board, graphite polystyrene board, perlite board, graphite extruded board, extruded board, foam glass, etc. The thickness of the insulation layer can be determined according to the heat transfer coefficient of the wall. To adjust, in this embodiment the material of the insulation layer is a rock wool composite board with a thi...

Abstract

The invention belongs to the technical field of building material preparation, and particularly relates to a de-molding-free heat preservation structure integrated plate and a preparation method and a construction method thereof. A first prefabricated structure can be used as an outer formwork, a prefabricated heat preservation module in a second prefabricated structure is used as an inner formwork, the inner formwork and the outer formwork are not needed in the construction process, the construction period is shortened, and the construction cost is reduced. According to the setting mode of a connecting male part in the first prefabricated structure, the connecting male part and the integrated plate are prefabricated together, and the procedure of installing a connecting piece on site is reduced; and through the arrangement of a steel wire mesh and the arrangement mode of the steel wire mesh and the connecting piece, the connecting male part can play a role in fastening the steel wire mesh, so that the overall performance of the integrated plate is improved.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a formwork-free thermal insulation structure integrated board, a preparation method and a construction method thereof. Background technique [0002] The thermal insulation structure integration technology solves the problem of the risk of insulation layer falling off from the construction point of view, but there are safety hazards such as cracking, water absorption, and falling off of the leveling layer caused by excessive thickness of the leveling layer, uneven leveling mortar quality and construction technology level. [0003] The main reason for the above problems is that the large-scale thermal insulation board technology is adopted in the external cast-in-place system of thermal insulation structure integration, and the strength of the inorganic mortar protective layer of the large thermal insulation board is low. This will lead to cracking...
