Abstract
The invention discloses a method for demoulding concrete prefabricated member, which is mainly aimed at solving the problem that a concrete prefabricated member (6) is difficult to be demoulded under the action of vacuum adsorption force. The method is characterized in that a plurality of air holes (2) are arranged at the bottom plate of a concrete die (1), the air holes (2) are connected with an air compressor (4) by an air tube (3).Before concrete is poured, a pressurizing cover plate (5) are covered at an air hole (2) at the inner side of the die, when the concrete reaches a certain strength, demoulding can be carried out, the air compressor supplies air, air pressure under the pressurizing cover plate separates the prefabricated member (6) from the concrete die (1).
Description
(1), technical field
The present invention relates to building field, specifically a kind of method for demoulding concrete prefabricated member.
(2), background technology:
In present precast concrete was produced, the demoulding was adopted mechanical more.Exist main problem to be: to choose many, efficient is low, the mould number of turnover is few, the mold repair amount is big, the concrete component profile is difficult to be kept perfectly, even can damages concrete component in the knockout course.
(3), summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of precast concrete demoulding simple high efficiency method.The effect of each several part composition of the present invention and each several part is as follows:
1, air compressor: the existing market can be supplied, and uses the product of 1.2Mpa at least, and the source of the gas of certain pressure is provided.
2, tracheae: using withstand voltage tracheae, can be steel pipe, helix tube, rubber tube etc., feeds air under pressure.
3, pore: diameter is identical with the tracheae external diameter, is connected with tracheae and to the ventilation of the interface of mould and precast concrete in order to mould.
4, supercharging cover plate: diameter provides big pressure greater than the circular arc plate of pore.
5, mould: for the box of concrete formation.
6, prefabricated component: the member that concreting forms in mould.
(4), description of drawings
Accompanying drawing 1 is that pore is provided with vertical view;
Accompanying drawing 2 is that A-A is to the section structure schematic diagram;
Mark in the accompanying drawing is represented respectively; Mould 1, pore 2, tracheae 3, air compressor 4, supercharging cover plate 5, precast concrete 6.
Claims (2)
1. a method for demoulding concrete prefabricated member is characterized in that: before the precast concrete demoulding, form an airtight air pressure system by air compressor (4), tracheae (3), mould (1).
2. a kind of method for demoulding concrete prefabricated member according to claim 1, it is characterized in that air compressor (4) and tracheae (3) are tightly connected, on at the bottom of the mould, establish one or above pore (2), one end of tracheae (3) is connected with pore (2) flange on the mould (1), is stamped supercharging cover plate (5) on the pore (2).
