Description

Sintered and foamed building block

The invention belongs to building material technical field, relate to a kind of sintered and foamed building block that is fit to as body of wall and roofing.

Body of wall and roofing are to use maximum a kind of construction materials in the building, with existing two history in more than thousand year of the production application of clay firing brick-and tile, the title of " Qin brick and Han tile " are arranged.But development so far, and clay tile still accounts for 90% of China's body of wall and roofing total amount, not only takes up an area of every year to ruin the field, and destroy ecology, contaminated environment, waste energy, thereby the reform of body of wall and roofing is a demands of social development.

Books such as " novel wall material " that " New Building Materials construction handbook " that China Construction Industry Press published in 1994 and Anhui Science Press publish in September, 1999, " glass pottery ornament materials ", the situation of having introduced China's present novel wall roofing glass pottery ornament materials development more all sidedly and having used.In the book novel wall material is divided into bulk, tabular, the composite wall three major types, the new type roof material is divided into the corrugated tile two big classes of air entrained concrete roof boarding and various materials, and glass pottery ornament materials is mainly used in the decoration on interior wall face, ground, and existing content is done wants brief introduction as follows:

One, block materials for wall mainly contains structural clay tile and non-burnedc lay brick, concrete or air-entrained concrete building block, non-clay bricks such as fly ash silicate.Though the block materials for wall of this class is compared with conventional clay, few with or without clay, reduced destruction, but still be manually to build a wall and interior exterior wall is wiped one's face the soil, it is time-consuming to build the house.

Two, tabular materials for wall mainly contains Thistle board and hollow lath, cement or gypsum particle board, glass curtain wall, glass fiber reinforced cement board, calcium silicate board with microporous, metal crimp template, composited aluminum and plastic decking, honeycomb sandwich panels etc.Though every of the tabular materials for wall of this class is wide about 1.2 meters, long about 3 meters, need not build a wall, great majority need site preparation that keel are installed, and block-by-block cuts off assembling, the whole construction course complexity.The tabular walling material of this class humidity resistance is relatively poor, and most only suitable as nonweight-bearing indoor partition wall, its comprehensive cost mostly is higher than common brick wall.

Three, main polystyrene of composite wall body material or polyurethane foaming sandwich composite plate, concrete rock wool compound external wall panel, steel wire foamed plastics wallboard, kinds such as SP pre-stress hollow wallboard.Composite wall body material adopts the material of each tool speciality, its Rational structure is composited, it is high-strength to have light weight, heat preservation and soundproof, but the structure of its MULTILAYER COMPOSITE makes production technology complicated, wide 1.2 meters more, and the size of long 7-12 rice still needs on-the-spot block-by-block to cut off the back assembling when construction, higher price and operating expenses are unfavorable for the large-scale popularization application.

Four, corrugated tile mainly contains asbestos cement ripple watt, and fiberglass ripple watt, plastics ripple watt and sheet metal ripple watt, the big ripple of this class watt are compared with clay shingle, and sun-proof, insulation, wind resistance are relatively poor, is mainly used in the non-thermal-insulating type pitched roof of factory building, storage shed or temporary building.

Five, air entrained concrete mainly contains steam pressurized and prestressing force air entrained concrete roof boarding, the wide 590-890 millimeter of this roof boarding, long 1800-6000 millimeter lifts according to roofing area block-by-block, and then do insulation room and watertight composition, be mainly used in industry and civil buildings flat roof deck.

Six, glass pottery ornament materials is mainly used in the decoration of building inside and outside wall face, needs block-by-block to paste assembling and installs.

Seven, the foam glass plate has the excellent insulating sound insulation value, but based on a large amount of cullet bits, and can not make large-scale plate.
