Abstract
The invention relates to a manufacture process of an ultralight foam cement-based heat-insulation metal-surface sandwich board used in a light steel plant. The manufacture process comprises manufacture of a metal surface layer and manufacture of a heat-insulation core layer, and comprises the following specific steps: A. pressing a metal board to form a bottom board and two side boards, which are of an integrated structure, additionally selecting steel boards as two end boards, welding and positioning the two end boards with the side boards and the bottom board, thus forming the metal surface layer of a groove type structure; B. pouring ultralight foam cement in the groove type structure, and carrying out initial set, thus forming the heat-insulation core layer; and C. pouring waterproof rapid-hardening type cement mortar on the heat-insulation core layer to serve as a waterproof cement mortar upper cover of the groove type structure, and positioning the upper cover together with the two side board and the end boards so as to a closed shell, thereby solving the defects that the existing heat-insulation metal-surface sandwich board is non-fireproof, the problems that the metal-surface sandwich board is settled and contracted and has reduced volume and increased heat-conducting coefficient after being moistened and the problem that the heat-insulation capacity is reduced, the metal board surface is subjected to corrosion and the whole strength is reduced due to the introduction of damp air caused by hollowing of a raised part when the metal-surface sandwich is in a corrugated shape.
Description
Technical field
The invention belongs to building field; Relate to the manufacture craft of a kind of light Steel-Structure Factory with Steel with the metal covering insulation sandwich board, particularly a kind of ultralightization and have fabulous heat-insulating property based on the light Steel-Structure Factory with Steel of ultralight foam cement material manufacture craft with the metal covering insulation sandwich board.
Background technology
Metal skinned sandwich panel is a kind of New Building Materials that are used to build various factory buildings, workshop, lightly constructed and simply equipped building, board house, warehouse that rose gradually in recent years.Since its good performance, the high convenient application property, and good heat insulation property is accepted extensively and is widely applied by people gradually.But metal decking sandwiched plate in the market has metal covering organic plastics insulation sandwich board, like polystyrene, hard-foam polyurethane etc., and good heat insulating but do not reach national fire protection requirement; Though metal covering rock wool, mineral wool sandwiched plate etc. have reached fire protection requirement; Its rock wool, mineral wool sandwiched plate are domestic many with two dimensional method production; It meets moisture laden air and the easy sedimentation of water volume is shunk and metal decking breaks away from, heat-insulating property reduces; And cost is higher, though performance increases when producing with 3D approach, cost is just higher.More than two kinds of plates when metal covering is corrugated, metal covering play tympanic part position hollowing, will get into moisture laden air, reduce insulating power, cause the corrosion of metal sheet face, also unfavorable to the bulk strength of plate simultaneously.
Light Steel-Structure Factory with Steel is with metal covering ultralight foaming cement thermal insulation sandwiched plate; But serialization, mechanization production; Realized ultralight, ultra-thin, do not fire, waterproof and reach the requirement of national building energy conservation 65%, at present, its manufacture craft has been become the key issue that needs to be resolved hurrily.
Summary of the invention
The present invention is low for the fire-protection rating that solves metal decking sandwiched plate of the prior art, heat insulation effect is poor and cost high, ropy problem; Designed the manufacture craft of light Steel-Structure Factory with Steel with metal covering ultralight foaming cement thermal insulation sandwiched plate; Serialization, mechanization production have been realized; Above-mentioned technology prepared metal covering insulation sandwich board, realized ultralight, ultra-thin, do not fire, waterproof and reach the requirement of national building energy conservation 65%.
The technical scheme that the present invention adopts is: light Steel-Structure Factory with Steel is with the manufacture craft of metal covering ultralight foaming cement thermal insulation sandwiched plate, comprises preparing metal faced and preparing the heat preservation core layer step with ultralight foam cement mortar, and concrete steps are:
A, pressing metal plates formed have integral structure base plate with two side plates, alternative with steel plate as two end plates, with side plate and base plate stationary positioned, the formation trench structure is metal faced;
B, in trench structure cast ultralight foam cement material, form heat preservation core layer after the initial set;
C, on heat preservation core layer cast waterproof fast gravity die cement mortar, as the cement mortar waterproof loam cake of trench structure, is connected with end plate with two side plates and locatees the formation closure casing.
The invention has the beneficial effects as follows: replaced the organic plastics warming plate with this incombustible material of ultralight foam cement material, when having reached basic suitable coefficient of thermal conductivity, solved the nonfireproof shortcoming of metal covering organic plastics insulation sandwich board; Overcome metal covering rockwool sandwich board, metal covering mineral wool sandwiched plate and made moist that back sedimentation contraction, volume reduce, coefficient of thermal conductivity improves shortcoming; Metal covering organic plastics insulation sandwich board, metal covering rockwool sandwich board, metal covering mineral wool sandwiched plate have been overcome when metal decking is corrugated, bossing hollowing and cause that moisture laden air get into to reduce insulating power, causes the corrosion of metal sheet face and causes slab integral intensity to reduce problem; Insulation sandwich board cost of the present invention is low, intensity is high, good integrity; When the cement mortar waterproof loam cake of this metal covering foaming cement thermal insulation sandwiched plate can have specific (special) requirements as aspects such as facing decoration or waterproof as basal layer; Also the fast gravity die cement self-leveling mortar of waterproof surface layer is directly poured into a mould on the surface above that; No longer do secondary waterproof and finishing, alleviated the construction burden like this.
Description of drawings
Fig. 1 is the first embodiment of the invention structural representation.
Fig. 2 is the second embodiment of the invention structural representation.
In the accompanying drawing, the 1st, trench structure is metal faced, and the 2nd, heat preservation core layer, the 3rd, cement mortar waterproof loam cake, the 4th, netted cushion coat, the 5th, turnup structure, the 6th, strengthen braced structures.
The specific embodiment
Light Steel-Structure Factory with Steel is with the manufacture craft of metal covering ultralight foaming cement thermal insulation sandwiched plate, comprises preparing metal faced and preparing the heat preservation core layer step with ultralight foam cement mortar, and concrete steps are:
A, pressing metal plates formed have integral structure base plate with two side plates, alternative with steel plate as two end plates, with side plate and base plate stationary positioned, formation trench structure metal faced 1;
B, in trench structure cast ultralight foam cement material, form heat preservation core layer 2 after the initial set;
C, on heat preservation core layer 2 cast waterproof fast gravity die cement mortar, as the cement mortar waterproof loam cake 3 of trench structure, is connected with end plate with two side plates and locatees the formation closure casing.
When this metal covering ultralight foaming cement thermal insulation sandwiched plate has solved existing metal covering insulation sandwich board and has been corrugated, bossing hollowing and cause that moisture laden air gets into and reduce insulating power, cause the corrosion of metal sheet face and cause slab integral intensity to reduce problem.
