(2) core that will be used to form described cavity then is arranged in the mould, and with mesh reinforcements separately

(3) pouring liquid compound in mould afterwards promotes mesh reinforcements one segment distance simultaneously;

(4) more thread reinforcing material is joined in the compound, and in the space between the core;

(5) make the liquid pourable compound sclerosis that is arranged in mould;

(6) core is withdrawn from from mould;

(7) demoulding.

Between step (1) and step (2), between core, reach the core upper surface and arrange thread reinforcing material; Between step (2) and (3), thread reinforcing material is set in mould.

The method that promotes mesh reinforcements in the above-mentioned steps (3) is: wedge block is set below mesh reinforcements, makes its wedge angle be close to the mould bottom surface forward and slide, thereby mesh reinforcements is added in the compound.

In step (3) before, the adiabator layer of link joint can be set on core, in step (6), core is withdrawn from from mould, makes core be retained in the compound of sclerosis; The shape of adiabator layer is corresponding with the shape of core, and adiabator layer be positioned at core above or below.

Core and adiabator layer are chimeric mutually at vertical direction, have draw-in groove such as core two upper lateral parts, and inside, adiabator layer both sides has projection, and projection can snap in the draw-in groove when resilient adiabator layer fell.

Core is withdrawn from from mould in the process, at first core and adiabator layer are thrown off, withdraw from core then, make adiabator layer be retained in the compound of sclerosis.

Adopt said method, owing to used mesh reinforcements at bottom, and in the process of cast, promote it, solve the air bubble problem that adheres to of bottom fiber net dexterously, made disposal pouring become possibility, obviously, because what adopt is disposal pouring, make that all parts of wallboard all are to solidify simultaneously, its interior tissue uniformity and high conformity, the performance and the mass ratio of product are higher; Also have simultaneously production efficiency height, cost low etc. advantage;
