preparation example Construction

[0028] like figure 1 As shown, the preparation method of the filling material of the non-dismantling lightweight self-insulation cast-in-place wall provided by the invention may further comprise the steps:

[0029] Preparation of nano- or micro-scale microcellular foam;

[0030] The microporous foam is fused with the inorganic composite gel matrix containing silicate, expanded and foamed to form a microporous slurry, and nano- or micron-sized closed cells are formed in the microporous slurry to make a lightweight porous refractory inorganic framework ;

[0031] Then use organic lightweight aggregate to fill the lightweight porous refractory inorganic framework to make a mixed slurry;

[0032] The mixed slurry is solidified and formed.

[0033] Preferably, the silicate includes calcium silicate and aluminum silicate, as an inorganic composite gelling matrix, which has high strength after curing and is suitable for building materials.

[0034] Preferably, polystyrene foam pa...

Embodiment 1

[0045] The keel frame 1 adopts C-shaped steel keel with a steel structure of 13cm, the outer wall panel 21 adopts 10mm thick Ozon board, the inner wall panel 22 adopts 12mm thick paper-faced gypsum board, and the wire pipes and wire boxes are pre-installed on the outer wall panel 21 and the filling space of the inner wallboard 22, and then pouring mixed slurry in the filling space, the mold does not expand and does not leak, and the mixed slurry solidifies to form a self-insulating wall.

Embodiment 2

[0047] The keel frame 1 adopts a 16cm I-shaped steel keel, the outer wall panel 21 adopts an 80mm thick aerated panel, the inner wall panel 22 adopts a 12mm thick GRC board, and the wire pipes and wire boxes are preset in the filling space. Install a reinforcing rib at the center of the pouring, and then pour the mixed slurry in the filling space, without expansion and no leakage of the slurry, and the self-insulating wall will be formed after the mixed slurry solidifies.

Abstract

The invention discloses a light non-dismantling self-thermal-insulation cast-in-place wall and a preparation method of filling material thereof. The preparation of the filling materials comprises the steps that micro-scale or micron-scale microcellular foam is prepared; the microcellular foam and inorganic compound gelatinization matrixes containing silicate are blended, microcellular slurry is formed through puffing foaming, and a light porous fire-resistant inorganic framework is prepared; the light porous fire-resistant inorganic framework is filled with organic lightweight aggregate, and mixed slurry is made; and the mixed slurry is solidified and formed. The light non-dismantling self-insulation cast-in-place wall comprises a keel frame, a non-dismantling wall plate fixed to the keel frame and the filling material. According to the light non-dismantling self-thermal-insulation cast-in-place wall and the preparation method of the filling materials thereof, no additional mould is supported, a pipeline can be embedded, construction is simplified greatly, cost is reduced greatly; in the casting process, plate expanding, template bursting and hollowing do not occur; the fireproof and self-insulation purposes are achieved, and thus no external thermal insulation needs to be conducted; seamless connection is achieved, and thus amount of steel used is reduced; weather resistance, the freezing and thawing resistance cycle and no crack are achieved, so that the service life of the wall is the same with that of a building; and no corrosion occurs, and thus a rust-proof role is played on a steel structure, and the service life of the steel structure is prolonged.

Description

technical field [0001] The invention relates to a building wall, in particular to a demolition-free lightweight self-insulating cast-in-place wall. Background technique [0002] With the continuous improvement of the country's requirements for building energy conservation, the demand for low-energy houses and light-weight and warm houses is increasing. Using light-weight cast-in-place filling walls with non-demolition formwork is the solution with the lowest cost and the best thermal insulation and energy-saving effect to meet the above requirements. Difficulty, the main reason is that due to the low consistency, high density and large volume of the filling slurry, mold expansion and slurry leakage are prone to occur, and because of the large expansion and contraction after curing, it is very easy to separate from the non-demolition formwork. [0003] It can be seen that the current non-demolition formwork filling wall has the problems of easy expansion and separation from ...
