Abstract
The present invention relates to a light wallboard which is made from cement, pearlite, gypsum, alumina, fireproofing materials, glass fibre and water, wherein the glass fibre is laid in a protecting layer. According to the different thickness of the wallboards, the present invention can be made into a hollow board thin wallboards with double-row holes and single-row holes, and the thin wallboard without holes. The present invention is especially suitable for tall frame buildings. Compared with the existing reinforced concrete prefabricated wallboard or the brick wall, the present invention has the characteristics of light weight, heat insulation, fire resistance, and noise absorption and has the advantages of cement and cement saving, simple manufacturing process, convenient construction, capable of being sawed capable of being planned, etc.
Description
Light trabs of the present invention, it relates to a kind of concrete composition, a kind of building unit that particularly utilizes the light weight of perlite, refractory material and glass fiber etc., characteristic such as heat insulation to make.
Along with developing rapidly of China's construction business, highrise building is more and more many, and for adapting to shockproof requirements, many high-rise buildings adopt frame construction to assemble the reinforced concrete prefabricated wallboard or the wall of laying bricks, reinforced concrete prefabricated wallboard needs great deal of steel and cement, and lifting construction is time-consuming, effort; The globality of brick wall and anti-seismic performance are all poor, and it is slow that progress is built at the scene by laying bricks or stones, need manpower many.
Be the weak point of avoiding above-mentioned prior art to exist, the invention provides a kind of light weight concrete construction of forming with cement, perlite, refractory material etc., and replace the Light trabs of reinforcing steel bar laying in topping with glass fiber.
The objective of the invention is to realize by following measure: Light trabs is made of topping, glass layer and intermediate layer.Glass layer adopts filament of glass fibers, is tiled in length and breadth between topping and the intermediate layer, plays tension shearing resistance effect, and its weight is 1～2% of wall board material.The other materials weight proportion that constitutes wallboard is: cement 20～25%; Perlite 20～25%; Gypsum 2～3%; Alumina 2～3%; Refractory material 5～8%(is Al wherein
2O
3Respectively account for 50% with white cash soil); Water 30～35%.When manufacturing, earlier lysed gypsum of cement, perlite, refractory material and water and alumina are put into mixer by weight ratio, once add water, after stirring, be poured into mould, and the moulding of vibrating.
Description of drawings is as follows:
Fig. 1 is a single row of holes hollow wall panel schematic diagram
1-topping among the figure, 2-glass layer, 3-intermediate layer.
Below in conjunction with drawings and Examples the present invention is further described: referring to Fig. 1, the present invention is a kind of Light trabs, and it is by topping (1), glass layer (2) and intermediate layer (3) formation.Glass layer (2) adopts filament of glass fibers, is tiled in length and breadth between topping (2) and intermediate layer (3), and it replaces the reinforcing bar in the existing reinforced concrete wall panel, plays tension shearing resistance effect, and its weight accounts for 1～2% of wall board material.Topping (1) and intermediate layer (3) are with cement 20～25%; Perlite 20～25%; Gypsum 2～3%; Alumina 2～3%; Refractory material 5～8%(is Al wherein
2O
3Respectively account for 50% with white cash soil); The light weight concrete construction that water 30～35% is formed.When manufacturing, lysed gypsum of cement, perlite, refractory material and water and alumina are put into mixer by weight ratio, once add water, after stirring, be poured into mould.
According to wallboard thickness, can implement dissimilar wallboards, and lay the glass fiber of the different numbers of plies.
A. double hole hollow wall panel is used for exterior wall, and thickness of slab is no more than 24cm, in the topping (being not less than 3cm) of two plate faces and respectively spread layer of glass between two rounds.
B. the single row of holes hollow wall panel is used for exterior wall or interior wall, and thickness of slab is no more than 12cm, respectively spreads layer of glass in two plate face toppings.
C. the atresia thin plate is used for interior wall, and thickness of slab is not less than 6cm, shop layer of glass in the middle of plate.
Wallboard is fastening with clamping plate with the framework junction up and down, and bolt connects.Adjacent wall board available water earth rubber bonding, glass fabric seals.
The wallboard of cast, initial set in 40 minutes, final set in 10 hours, the compressive strength after three days is 8.2mpa; Rupture strength is 9.4mpa; Water absorption rate reaches 13.1%.
The present invention compare with existing reinforced concrete prefabricated wallboard have light weight, the characteristic of insulation, fire prevention, sound absorption, and save cement, steel, manufacture technology is simple, easy construction can be sawed, and can dig etc. excellent The point. Compare with brick wall, except above advantage, it is strong also to have globality, and anti-seismic performance is good, human-saving, high efficient construction.
