Abstract
The invention relates to a kind of thin concrete inner tube. It is made from in proportion 1 concrete, sand 1~3, water 0.3~0.7, short fiberglass shred or intermediary alkali shred 0.02~0.05, length of which is about 6~16mm.The method to make the thin concrete inner tube is as following: mix the material equably and then put them in the module. Put the module in rotating container that is fixed on the driving device and fix two boards at the position opposite to the two sides of the module. Rotate the rotating container for a certain time. Take out the module and get the finished product. The tube made by the above step is light and high intensity. Because it is simple using the invention can finish shaping with only one step so it can save the production time and the cost.
Description
Technical field
The present invention relates to a kind of cement thin-walled pipe and manufacture method thereof.
Background technology
Advantages such as cast-in-situ hollow floor plate is good from heavy and light, globality and continuity with it, construction is simple have been widely used in the various buildings.The construction method of cast-in-situ hollow floor plate is earlier steel bar framework to be arranged on floor location, places thin wall cement pipe, cast concrete then again in steel bar framework.Existing cement thin-walled pipe is to be made of cement, sand, water and grid cloth or glass layer.During making, the slip that will contain glass layer or grid cloth earlier is laid on the template, makes finished product through maintenance, the demoulding again.The problem that above-mentioned cement thin-walled pipe exists is that Heavy Weight, intensity are low, and the production process complexity, the production cycle is long, manufacturing cost is high.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of in light weight, intensity is high, but the simple one-shot forming of production process, the cement thin-walled pipe and the manufacture method thereof of with short production cycle, low cost of manufacture.
Consisting of of this cement thin-walled pipe: according to ratio of weight and number, basic composition is 1 part of cement, sand 1-3 part, water 0.3-0.7 part, the short chopping of alkali-resistant glass fibre or the short chopping 0.02-0.05 of medium-alkali glass fibre part, the length that said alkali-resistant glass fibre is lacked chopping or the short chopping of medium-alkali glass fibre is 6～16mm, and alkali-resistant glass fibre is lacked chopping or the short chopping of medium-alkali glass fibre is evenly distributed in this cement thin-walled pipe.
According to above-mentioned cement thin-walled pipe, also contain flyash 0.05-0.3 part.
A kind of manufacture method of cement thin-walled pipe is: get 1 part of cement according to ratio of weight and number, the short chopping of sand 1-3 part, water 0.3-0.7 part and alkali-resistant glass fibre or the short chopping 0.02-0.05 of medium-alkali glass fibre part, the length of short chopping of said alkali-resistant glass fibre or the short chopping of medium-alkali glass fibre is 6～16mm, and above-mentioned each component is mixed; Mixed slurry is contained in the cement thin-walled pipe formation die tool, again cement thin-walled pipe formation die tool is placed in the rotating cylinder, said rotating cylinder is installed on the rotating cylinder drive unit, and place and fixing closure plate through moulding in advance at corresponding cement thin-walled pipe formation die tool two ends in rotating cylinder, preestablish motor revolution and working time in the rotating cylinder drive unit, make the rotating cylinder rotation, after the scheduled time, make the rotating cylinder stall; Open rotating cylinder again, take out and open cement thin-walled pipe formation die tool, obtain this cement thin-walled pipe finished product.
According to the manufacture method of above-mentioned cement thin-walled pipe, in mixed slurry, also add flyash 0.05-0.3 part, to increase the opposite sex of closing of this cement thin-walled pipe, prevent that crackle from appearring in tube wall.
Advantage of the present invention is owing to adopt short chopping of alkali-resistant glass fibre or the short chopping of medium-alkali glass fibre, and short chopping of alkali-resistant glass fibre or the short chopping of medium-alkali glass fibre are evenly distributed with all directions in cement thin-walled pipe.Therefore, the cement thin-walled pipe that makes is in light weight, intensity is high.The manufacture method production process of this cement thin-walled pipe is simple, can make body and end plate one-shot forming, with short production cycle, low cost of manufacture, and can impel short chopping of alkali-resistant glass fibre or the short chopping of medium-alkali glass fibre more to be evenly distributed in the cement thin-walled pipe, to improve the intensity of cement thin-walled pipe.
