Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] As can be seen from the accompanying drawings, the outer surface of the mold 1 is rolled with a plastic film 2 that can be used repeatedly. The mold 1 can be a round tube, a square tube or any geometry. The diameter and length of the mold 1 can be any size. Spread the cement slurry 3 on the woven cloth 4, and scrape it flat with a scraper, compact it, and finally place the mold 1 that is rolled with the plastic film 2 on the woven cloth 4 that has been spread the cement slurry, and place the mold 1 that has been rolled with the cement slurry The woven cloth 4 is rolled up to obtain an ultra-thin cement core pipe for the wall; then, after curing, the cement slurry is solidified, the mold and the plastic film are pulled out, the two ends of the cement pipe are cut, and the end caps are sealed.

Abstract
The invention provides an ultra-thin cement core pipe for the wall body and the manufacture method. The invention is mainly characterized in that after an end cover is prefabricated, a cement slurry material is paved on a knitting cloth and is scraped and compactly pressed by a scraper; a layer of plastic membrane which can be repeatedly used is coiled on the circumference of a die; the die coiling the plastic die is arranged and coiled on the knitting cloth where the cement slurry material is paved till the cement slurry material is concreted; the die is pumped out, both ends of the cement pipe are cut, the end cover is sealed, and the forming process is implemented. The external surface of the die is coiled with a layer of reusable plastic membrane. The invention has the advantages of saving a plurality of raw material, low labor intensity, simple and feasible method, high production efficiency, reduction in the cost of products, no cracks of the made wall body, high economic benefit and obvious social benefit.
Description
technical field [0001] The invention relates to a cement core pipe for building components and a manufacturing method thereof, in particular to an ultra-thin cement core pipe for walls and a manufacturing method thereof. technical background [0002] At present, there are two methods for manufacturing cement core pipes, one is internal mode, and the other is external mode. The cement pipe cores manufactured by this method are all over 5mm in thickness and heavy in weight. Most of the tube core diameters used for the wall are below 90mm, so the length of the core tubes manufactured by these two methods is limited, and there are great disadvantages. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the above-mentioned technologies, and to provide an ultra-thin cement core pipe for walls with simple operation, various diameters, various shapes, and arbitrary lengths and a manufacturing method thereof. [0004] The obje...
