Description

Technical Field [0001] The present invention relates to a continuous sequential multi-layer concrete panel manufacturing apparatus,

The present invention relates to an apparatus for manufacturing a multilayer concrete panel comprising an outer panel (2) and a charging body (1), wherein vertical conveyor vertical belts (20) are in close contact with both sides of the horizontal belt A plurality of nozzles are provided on the upper side of the belt 10 so that the outer plate 2 and the charging body 1 are formed by ejecting the concrete in a state where the horizontal belt 10 and the vertical belt 20 are circulated.

As shown in Fig. 1, the multilayer concrete panel in which the outer panel 2 covers both sides of the charging body 1 made of a light and heat insulating material is easy to secure the heat insulation and lightweight, has excellent structural rigidity and durability, And is widely utilized as a sheet member and a finishing material in various construction work as well as an exterior material.

In such a multi-layered concrete panel, foam concrete is used as the filler 1, and quick-setting cement or crude steel cement is used as the sheathing 2. Usually, curing is carried out in a rectangular mold, Layered concrete panel is put in such a manner that the outer plate 2 in the form of a finished plate is inserted and the filler 1 is laid thereon or once the outer plate 2 is poured and cured, .

In other words, conventional multi-layered concrete panel manufacturing method is a discontinuous manufacturing method in which a mold is indispensable, and since a process including mold building, casting, curing and demolding is performed step by step, there is a limit to securing productivity.

Accordingly, in the manufacture of the multi-layered concrete panel, the mold is excluded and the concrete panel is continuously extruded while pouring the concrete directly into the circulating conveyor, and then the concrete panel is cut according to the desired standard to complete the multi- Multilayer concrete panel manufacturing equipment has been developed, which can dramatically improve the productivity of multilayer concrete panels.

The continuous multi-layer concrete panel manufacturing apparatus of No. 1570090 is installed in a state where a pair of standing conveyor belts are slightly spaced from each other and a concrete is laid between the pair of conveyors to manufacture a panel. However, since the concrete pouring and curing proceed between the standing conveyor, there is a problem in that the material constituting the concrete panel must be separated and biased.

That is, in the conventional continuous multi-layer concrete panel manufacturing apparatus of Patent No. 1570090, the concrete is not placed and cured in a state in which the concrete panel is horizontally seated, but the concrete panel is vertically erected, The depth of the material is inevitably formed deep in the fluidized state or during the curing process. As a result, the heavy material in the charged material is precipitated to the lower side of the manufacturing apparatus and the lightweight material is separated from the material floating upward , Which may lead to bias in the degree of compactness in the finished panel structure, resulting in poor overall quality such as uniformity, strength and durability of the panel.
