Abstract
The present invention relates to light heat-insulation wall body material which is formed by using cement expanded perlite concrete as a main body and respectively compounding one layer of foaming polystyrene concrete coating layer on the inner and the outer surfaces or mixing the expanded perlite, foaming polystyrene concrete, etc. The material can be made into wall body members with special structures. After a wall body is built on the spot, horizontal and vertical hole channels, which are mutually communicated, are formed in the inner part. Liquid concrete is poured in the hole channels on the wall which face an opening, and a building board can also be simultaneously poured to naturally form a building entirety of a lattice type. The light heat-insulation wall body material has the characteristics of energy saving, shock resistance, light weight, no use of red bricks, high construction speed, wide application range, etc., and is especially suitable for the hot climate of the south and the cold climate of the north.
Description
The present invention relates to construction material.
At present, the body of wall of domestic building construction is to use clay solid brick to build by laying bricks or stones substantially, has not only damaged a large amount of farmlands, and production energy consumption and building heating energy consumption are bigger.Therefore, greatly develop energy-conservation, save land, sharp useless, heat insulation novel wall material, accelerate the materials for wall innovation, advancing building energy conservation work is an instant major issue.In recent years through the practice of materials for wall innovation and building energy conservation, develop some novel walls, structural clay tile body of wall, various concrete holllow building block wall are wherein arranged, and aerated concrete wall is with brick and rock wool is compound or brick and polystyrene board compound combined wall.The unit weight and the heat-insulating property of structural clay tile body of wall are better than clay solid brick, and its production energy consumption is also lower, bake bricks but still will ruin the field, and can't satisfy degree-days of heating period in geographic building energy conservation requirement more than 4500 with the thick hollow brick wall of 49cm.Various concrete holllow building block walls, it is wide to have a material source, and technology is simple, advantages such as easy construction, but degree-days of heating period adopts the single concrete holllow building block wall of 50cm to be difficult to satisfy energy-conservation requirement in area more than 4500.It is low that aerated concrete wall has unit weight, and advantages such as workability and good heat preservation performance are applicable to the wide geographic area from south to north, but to degree-days of heating period at the severe cold area more than 4500, note frost damage, and decorate bad processing outward that operation is also complicated.The combined wall good heat insulating can reach energy-conservation requirement, but the combined wall that has still will adopt clay brick, constructs bad processing simultaneously, poor seismic behavior.
The object of the present invention is to provide a kind of thermal conductivity low, the materials for wall of sufficient intensity, weather resistance, workability and the adhesive power of plastering is arranged, its performance satisfies the requirement of lattice texture building system or other building system non-bearing wall bodies.
In order to achieve the above object, technical solution of the present invention realizes as follows.Light heat-insulation wall material of the present invention is based on the cement expanded perlite concrete, within it, the compound one deck foamed polystyrene concrete of outside surface cladding.
Expanded perlite concrete is made up of pearlstone and cement, the two weight percent is a pearlstone 56～59, cement 41～44 adds water, water weight 0.5% water-holding agent, cement weight 0.02% air entrapment agent and cement weight 2% setting accelerator of cement weight 220～250% again.
Foamed polystyrene concrete is an aggregate with the polystyrene foamed particle, adding cement and flyash forms, the weight percent of each composition is a polystyrene foamed aggregate 5.5～5.7, cement 67～68, flyash 26～27, the water that adds cement and flyash gross weight 57% again, cement weight 0.25% water reducer, cement weight 0.02% air entrapment agent and cement weight 2% setting accelerator.
Characteristics such as pearlstone and concrete thereof have the heat-insulating property height, and the wide and cost in source is low, but the high poor adhesion with motar of water-intake rate, so, fail to become the material of main part of body of wall always.The foamed polystyrene concrete water-intake rate is low, and the frost resistance height has the enough toughness and the adhesive power of motar.The different characteristics that technical solution of the present invention is based on two kinds of materials is the materials for wall main body with the expanded perlite concrete, and its two sides cladding foamed polystyrene concrete forms.This composite wall body material had both had lower thermal conductivity, also had heat-insulating property preferably, had improved the water-absorbent of materials for wall again, frost resistance, and with the adhesive power of motar, also can reduce the breakage rate of wall body construction in transportation and installation process.
The expanded perlite concrete water-intake rate is up to 110～130%, being converted to the volume water absorption rate is 38～46%, but it has the heat-insulating property height, the source is wide, characteristics such as cost is low are widely used in the thermal insulation of industrial thermal apparatus and the insulation of building roof, in this occasion because of waterproof layer is arranged, frost resistance is not done requirement, but must satisfy the requirement of heat-insulating property and anti-freezing property as materials for wall.
The proportioning that proposes by the present invention after stirring by forced mixer, when reaching certain intensity, then has good frost resistance, and freeze-thaw cycle can reach 25 times.To further improve with the compound frost resistance afterwards of foamed polystyrene concrete, and can reach more than 25 times, water-intake rate reduces to 42%, and being converted to the volume water absorption rate is 22%, and as considering the waterproof action of surface of wall waterproof mortar, water-intake rate also will descend.
Materials for wall after the present invention is compound between two kinds of concrete interfaces, and all has quite high cohesive strength between foamed polystyrene concrete cladding and the plastering sand etc., the globality that still remains intact through 25 times freeze-thaw cycle.
Materials for wall of the present invention has the following advantages:
1, has excellent insulating performance and anti-freezing property.With the thick body of wall of 38cm (the load-bearing reinforced concrete member that comprises heat-insulating property difference in the body of wall) is example, and average thermal resistance reaches 2.181m
2K/w is equivalent to the thick clay brick wall heat resistance of 1m (1.44m
2K/w) 1.7 times, and freeze proof label reaches 25 times.Therefore materials for wall of the present invention can reduce the heating power consumption, is fit to the high subtropical zone of severe cold area and temperature and uses.Materials for wall performance of the present invention and body of wall under different thickness heat transfer coefficient and thermal resistance shown in table 1, table 2.
