Abstract
The hole forming hollow pipe is produced by mixing crushed high strength low-alkali cement, flyash, plant fiber, polyacrylic acid latex, high-efficiency water reducing agent, talcum powder, fine sand, light calcium carbonate, dispersant, sodium methyl silicate, methyl cellulose and water and other steps. It has simple production process, good concrete-bonding performance, light weight, high strength, high water absorption, high impact strength and fireproof performance, and may be used widely in building.
Description
Technical field:
The present invention relates to cassette ceiling production technical field for building, especially disclose a kind of hole forming hollow pipe specially for cast-in-situ steel reinforced concrete hollow plate.
Background technology:
At present, the cast-in-place reinforced concrete hollow slab of utilizing the pore-forming hollow section to make is to bury special non-core-drawing pore-creating hollow section before building on coagulation in advance underground, is one with concreting then, thereby forms cast-in-place reinforced concrete hollow slab.Have stress performance good, reduce floor height, save material, alleviate dead load, advantage such as quick construction.The pore-forming hollow section of cast-in-situ concrete hollow slab commonly used mainly contains ripple sheet steel pipe, paper tube, hard plastic tube etc., and the said goods uses the price comparison costliness, is difficult to be promoted the use of on engineering, has influenced this The Application of Technology.
Summary of the invention:
The problem to be solved in the present invention provides a kind of hole forming hollow pipe specially for cast-in-situ steel reinforced concrete hollow plate, greatly reduces the cost of production of hollow section, can be widely used in technical field of buildings.
Technical scheme of the present invention is to be raw material with inorganic coagulation material, flyash, string, high molecular polymer, fiber reinforced material, is mixed and made into by moulding process.
Concrete prescription following (by ratio of weight and the number of copies):
High-strength low alkali cement 1, flyash 0.1～0.8, string 0.1～0.8,
Polyacrylic acid latex 0～0.20, high efficiency water reducing agent 0.01, French chalk 0.1～0.4,
Fine sand 0.1～1.0, precipitated calcium carbonate 0～0.2, dispersing agent 0～0.01,
Sodium methyl silicate 0.005～0.02, methyl cellulose ether 0～0.005, water 0.3～0.8.
Production technology is as follows:
Take by weighing raw material according to the above ratio, be ground into 80 order fine powders, add the entry mixing and stirring, pave moulding in the cast hollow tube mode, precuring 2～4 hours, product is made in maintenance after the demoulding.
Good effect of the present invention is: production process is simple, product and concrete excellent bonding performance, light weight, intensity height have that water absorption rate is low, impact resistance and good characteristics of fireproof performance, the product cost of raw material is cheap, can extensively promote the use of in building field.
The specific embodiment:
Embodiment 1
Get high-strength low alkali cement 10kg, flyash 3kg, string (sawdust) 5kg, polyacrylic acid latex 2kg, high efficiency water reducing agent (UNF) 0.1kg, French chalk 4kg, fine sand 7kg, precipitated calcium carbonate 1KG, dispersing agent (NNO) 0.1kg, sodium methyl silicate 0.08kg, methyl cellulose ether 0.05 adds water 5kg mixing and stirring, build the filling mould, the moulding precuring, finished product is made in the demoulding maintenance.
Embodiment 2
With the high-strength low alkali cement of 100kg, 50kg flyash, 40kg string (powder of straw) polyacrylic acid latex 2kg, high efficiency water reducing agent (FDN) 1kg, French chalk 40kg, fine sand 80kg, precipitated calcium carbonate 10kg, dispersing agent (NNO) 1kg, sodium methyl silicate 1kg, methyl cellulose ether 0.5kg, water 50kg, stir after the mixing, injection molding, pave, moulding, precuring, demoulding, maintenance make finished product.
