Abstract
The invention discloses a non-bearing wall body by gypsum pouring formed by a plurality of hollow gypsum keels and the gypsum encapsulating the keels. The gypsum is obtained by situ casting of a gypsum slurry, wherein each material weight part of the gypsum slurry is: 80-95 parts of a semi-hydrated gypsum powder, 3-15 parts of a batch, 0.5-2.5 parts of an air-leading water-reducing agent, and a water-solid ratio is 0.5-0.7. The semi-hydrated gypsum powder is a semi-hydrated natural gyspsum, a semi-hydrated phospho gypsum or a semi-hydrated desulfurized gypsum. The batch is one, two or more than two of a fly ash, a blast furnace slag and a cement. The air-leading water-reducing agent is one, two or more than two of a triterpenoid saponim, a calcium lignosulphonate, sodium beta-naphthalene sulfonic. The gypsum keels are formed by a hollow straight tube (1) and a thin straight tube (2) with holes (3) arranged on both ends of the hollow straight tube. The invention has high construction efficiency and high quality of the wall body and can greatly reduce labor intensity and enjoy low cost.
Description
Technical field
The present invention relates to building materials field, relate in particular to non-bearing wall body.
Background technology
At present building field has non-bearing wall body miscellaneous, and selecting for use more is 240mm solid clay brick, structural clay tile, haydite hollow brick, concrete hollow block, cinder building-block and air-entrained concrete building block etc.Its construction technology is that traditional-handwork is built by laying bricks or stones, plastered basically, and labour intensity height, efficient are low, complex procedures, progress are slow, and all wet trade, particularly clay solid brick, has been subjected to the strictness restriction of policy.The present effect that adopts flyash hollow batten or gypsum lath construction is than high several times of building block, and floor space is little, but most batten exists the weakness that can't overcome: weight is big, transportation is inconvenient, breakage rate is high, the body of wall seam is easy to crack etc.Also has prefabricated three-in-one exterior wall plate in addition, it is with space enclosing structure layer (generally being steel concrete), insulation layer (polyphenyl plate or rock cotton board) and outside finish three unification, in factory's time processing moulding, directly installs to on-the-spot, but production technology more complicated, cost are too high.Adopt traditional gypsum plank to add the lightgage steel joist frame and make vertical partition wall, then exist not sound insulation, not durable, many shortcomings such as shock resistance is poor, moisture-sensitive cracking.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and a kind of efficiency of construction height is provided, wall quality is good, can alleviate labor strength and the low non-bearing wall body featuring plaster pouring of cost greatly.
Another object of the present invention also is to provide the preparation method of this non-bearing wall body featuring plaster pouring.
Non-bearing wall body featuring plaster pouring of the present invention, by some hollow gypsum studs and the parcel keel gypsum constitute, gypsum is that the calcium plaster cast-in-site gets; Wherein each parts by weight of raw materials of calcium plaster is: semi-hydrated gypsum powder 80-95 part; Batch 3-15 part; Gas tracting subtractive agent 0.5-2.5 part; The water-solid ratio value is 0.5-0.7.
Above-mentioned non-bearing wall body featuring plaster pouring, wherein: semi-hydrated gypsum powder is the half water plaster of paris, half water ardealite or half water desulfurated plaster.
Above-mentioned non-bearing wall body featuring plaster pouring, wherein: batch be in flyash, blast-furnace cinder, the cement a kind of, two or more.
Above-mentioned non-bearing wall body featuring plaster pouring, wherein: gas tracting subtractive agent be in triterpenoid saponin, calcium lignosulfonate, the sodium a kind of, two or more.
Above-mentioned non-bearing wall body featuring plaster pouring, wherein: gypsum stud constitutes one by hollow straight tube and the with holes thin straight tube of being located at the hollow straight tube two ends and forms.
The preparation method of non-bearing wall body featuring plaster pouring of the present invention may further comprise the steps:
(1) the molded work of body of wall: emit the body of wall position line in body of wall to be cast position, select engineering plastics plate or other light material thin plate according to body of wall shape to be cast and size then, assembly unit engineering plastics plate, couple together with the plate of gypsum stud body of wall mould two sides, the sprue gate is left at body of wall mould middle part, exhaust opening is left at the top, checks simultaneously whether sprue gate and exhaust opening be unobstructed;
(2) cast in: after treating that the molded work of body of wall finishes, be connected with the sprue gate of template with watering pump priming.The calcium plaster that stirs is poured in the grouting machine, and unlatching is watered pump priming and is poured into a mould, and when gypsum slurry is overflowed from exhaust opening, stops cast;
(3) dismounting body of wall mould: after treating that body of wall solidifies fully, engineering plastics plate or other light material thin plate are removed, order is removed gypsum stud two ends redundance from top to bottom, and Puttying gets final product on body of wall.
The present invention compared with prior art has tangible advantage and effect.By above technical scheme as can be known, be assembled into the body of wall mould, both satisfied the needs of the different-thickness of body of wall, also alternative plaster leveling layer by engineering plastics or other light material thin plate; Adopt gypsum stud, both regular worker's engineering plastics plate formed whole non with the gypsum of pouring into a mould again simultaneously.In the gypsum cast non-bearing wall body, after calcium plaster solidified, itself and gypsum stud formed complete one, and the surface of wall after the moulding is more smooth, need not at the plaster leveling layer, only needed Puttying to get final product.Batch can reduce water absorbing capacity, improves the moistureproof ability of gypsum wall; Improve the intensity of body of wall simultaneously, reduced wall crazing.Gas tracting subtractive agent can reduce the mixing water amount, is beneficial to improve strength of wall body and durability; Improve the mobile performance of calcium plaster simultaneously, need not make each corner that bobbing machine just can be filled into calcium plaster shell firm by ramming, in conveyance conduit, can not block because of gypsum sets.Thereby body of wall has protection against the tide, anti-be full of cracks, and sound insulation, heat insulation effect, and have higher intensity.Simultaneously, can adopt mechanized construction, the body of wall moulding is fast, and the demolition works plastics are fast, can alleviate labor strength greatly, thereby its efficiency of construction height, and wall quality is good, can alleviate labor strength greatly and cost is low
