Embodiment 1

[0035] a. Take by weight percentage 44 kilograms of known Sorel (Sorel) cement, 31.5 kilograms of fly ash, 19.8 kilograms of light aggregate, 2.2 kilograms of reinforcing materials, and 2.5 kilograms of stabilizers. Among them, the fly ash should meet the technical requirements of GB1596 for Class III fly ash; the light aggregate can be a combination of EPS particles, rice husks, sawdust, light volcanic ash, water-increased perlite, and plant fibers (straw, wheat straw, etc.) one or several kinds; the reinforcing material is ordinary glass fiber or chopped polypropylene fiber; the stabilizer is sulfuric acid or oxalic acid, and the weighed raw materials are placed in a concrete mixer and stirred evenly; of course, the currently disclosed light, High-strength base material;

[0036] b. Inject the uniformly stirred material into the mould, tap it firmly and flatten it to form the substrate 1 blank;

[0037] c. Place the thermal insulation partition 3 on the substrate 1 blank, t...

Embodiment 2

[0041] a. take by weight percentage 41 kilograms of known Sorel (Sorel) cement, 25.5 kilograms of fly ash, 25 kilograms of light aggregate (wherein sawdust 15 kilograms, increase water perlite 10 kilograms), glass fiber 2.2 kilograms, 1.8 kilograms of sulfuric acid, the weighed raw materials are placed in a concrete mixer and stirred evenly;

[0042] b. Inject the uniformly stirred material into the mould, tap it firmly and flatten it to form the substrate 1 blank;

[0043] c. Place the insulation partition 3 on the substrate 1 blank, use Figure 4 The shown diameter is 25 ~ 35mm, and the cylindrical hard miscellaneous wood reinforcing rib 5 with grooves 7 on the left and right sides of the upper and lower ends passes through the hole 4 on the insulation partition 3, and its end and the groove 7 at the lower end are inserted into the base plate 1 In the blank, the centerlines of the grooves 7 on the left and right sides are preferably not on the same straight line, and the th...

Embodiment 3

[0047] a. Weigh 42 kilograms of known Sorel cement, 33.2 kilograms of fly ash, 20.8 kilograms of light aggregate (including 0.8 kilograms of EPS particles and 10 kilograms of rice husks), 2.0 kilograms of glass fiber, and 3.5 kilograms of oxalic acid by weight percentage. kg, put the weighed raw materials in a concrete mixer and stir evenly;

[0048] b. Pour the evenly stirred material into the mold. The mold is composed of a side mold and an end mold. There is a mold hole for inserting the core tube on the end mold. The side mold and the end mold are connected by bolts, and they are pressed firmly to form a thickness of 110-150mm. Base plate 1 blank, ribs 5 can be set according to the area of ​​base plate 1, generally 6-8 can be set;

[0049] c. Place the insulation partition 3 on the substrate 1 blank, use Figure 4 The cylindrical reinforcing rib 5 with a diameter of 25-35mm and grooves 7 on the left and right sides of the upper and lower ends passes through the hole 4 on ...

Abstract

The present invention discloses a precast light insulation composite wall panel comprising light substrate (1), (2), a heat preservation separation panel (3) is arranged between the light substrate (1), (2), a hole (4) vertical to the panel is arranged on the heat preservation separation panel (3), the center of the strengthening rib (5) passes through the hole (4), and the two end surfaces are separately arranged on the light substrate (1), (2). The structure design of precast and having strengthening rib can improve the bonding force between the substrate and the heat preservation panel, such that the thickness of the substrate can be 110-150mm, the conductive ratio of production is small (to be 0.674w / m.k by detection), which can be used on heat preservation of outer wall, and the problem of secondary operation to carry out 'heat preservation technique of outer wall', which can save manpower, material resources and time.

Description

Technical field: [0001] The invention relates to a thermal insulation composite wallboard, in particular to a prefabricated lightweight composite wallboard suitable for external wall thermal insulation. Background technique: [0002] At present, in order to reduce the thermal conductivity of the wall and meet the requirements of building energy saving, people have invented a variety of wall insulation materials and methods, but there are different shortcomings in the specific implementation. [0003] The patent application document with the patent application number 021100965.6 discloses a "light heat insulation, high strength, sound insulation, wear-resistant composite wall material", which is composed of coated glass fiber reinforced cement material board and high molecular polymer through adhesive compound It is made, that is, two coated glass fiber reinforced cement material boards are first made, and then polystyrene foam is sandwiched between the two boards with epoxy ...
