Method for pore forming in building member by using self-pressurized expansible mold and mold release

Abstract

A method for pore forming in a building member by using a self-pressurized expansible mold and mold release comprises the following steps of pressing a push rod of the mold into a hard housing till a piston arrives at a lower-portion extreme position, remarkably compressing a spring, inserting a positioning pin into a positioning groove, and locking the position of the push rod; turning on a water inlet valve and a water outlet valve of the mold, filling water into a cavity and an expansion cavity through a water inlet pipe, meanwhile discharging air through a water outlet pipe, turning off the water outlet valve after the cavity and the expansion cavity are full of the water, enabling a soft casing to expand under the water pressure effect, and turning off the water inlet valve after water pressure in the mold and water pressure of a water source are balanced, wherein the soft casing is kept in an expanding state under the effect of water pressure in the mold. Therefore, technicians in the field provide multiple schemes for solving the problems. However, the disclosed methods have certain advantages.

Description

technical field [0001] The invention relates to a production process of a building component with holes, in particular to a method for making holes on a building component by using a self-pressurizing expansion mold and demoulding. Background technique [0002] Prefabricated elements manufactured in the construction sector have many structures with holes. When making prefabricated components, metal materials are generally used as hole molds for the formation of holes. When the concrete is solidified to a certain strength, the hole mold needs to be manually rotated or twitched to separate the hole mold from the concrete, which is convenient for smooth demoulding. When the strength reaches a higher level, the hole die is pulled out. The disadvantage of this method of forming holes is that: in the process of making prefabricated parts, it is necessary to manually rotate or twitch the mold one by one, which takes up a lot of human resources, the labor intensity of the workers i...

AI Technical Summary

Problems solved by technology

The disadvantage of this method of forming holes is that: in the process of making prefabricated parts, it is necessary to manually rotate or twitch the mold one by one, which takes up a lot of human resources, the labor intensity of the workers is high, and the production efficiency is low; the degree of solidification of the prefabricated materials needs to be accurately grasped. If the timing is not grasped, it is easy to cause damage to the solidified material, making it difficult to guarantee the quality of the hole. If the manual operation is not timely, the mold will not be able to be demoulded.

However, although these disclosed methods have certain advantages, they are complex in structure and complex in operation, which still cannot solve the above problems, and have not been applied in industrialized production so far.
