Composite aluminum alloy formwork and aluminum alloy mold for concrete curing
The invention discloses a one-way heat-preservation water-permeable membrane and a preparation method thereof, and further discloses a composite aluminum alloy formwork which comprises an aluminum alloy face plate, an aluminum alloy back plate and a plurality of end ribs. The aluminum alloy panel and the aluminum alloy back plate are arranged oppositely and are connected with each other; a plurality of drainage holes are formed in the aluminum alloy panel; the outer surface of the aluminum alloy panel is fully paved with a one-way heat-preservation water-permeable film, the one-way heat-preservation water-permeable film comprises a hydrophilic layer, a heat-preservation layer and a hydrophobic layer which are sequentially arranged, and the hydrophilic layer is attached to the outer surface of the aluminum alloy panel. The invention further discloses an aluminum alloy mold for concrete curing. The composite aluminum alloy formwork has the beneficial effects that the cavity is formed in the composite aluminum alloy formwork and covered with the one-way heat-preservation breathable film, water accumulated on the surface of the aluminum alloy face plate after pouring and vibrating is discharged, the water cement ratio of the concrete surface is reduced, the hydration reaction of components on the concrete surface is enhanced, meanwhile, apparent air holes of the concrete are reduced, and the concrete quality is improved. The concrete apparent quality is improved, and the rebound strength of a test piece is improved.
本发明公开了一种单向保温透水膜及其制备方法，还公开了一种复合式铝合金模板，包括铝合金面板、铝合金背板，以及多个端肋；所述铝合金面板与铝合金背板正对布置且相连；所述铝合金面板上开设有多个排水孔；所述铝合金面板的外表面满铺单向保温透水膜，单向保温透水膜包括依次设置的亲水层、保温层和疏水层，其中亲水层与铝合金面板的外表面贴合。本发明还公开了一种混凝土养护用铝合金模具。本发明的有益效果为：所述复合式铝合金模板内设置空腔，覆盖单向保温透气膜，将经浇筑振捣而聚集在铝合金面板表面的水份排出，降低了混凝土表面的水灰比，强化混凝土表面组分水化反应，同时降低了混凝土表观气孔，提高了混凝土表观质量，提升试件回弹强度。
